Patented Apr. 16, 1940 2@1979446 UNITED STATES@ PATENT OFFICE 21197,446 DOG P.ACING LURE APPARATUS ROY H. Alldritt, Miami, Fla. Application Aug-ust 13, 1936, serial No. 95,896 4 Claims. My invelition relates to dog racing lure apparatus, andparticularly to @a device of this character i .ntended and adapted to carry and move a rabbit, or other dog racing lure along or over the course of a dog racing track, and to actuate and control the lure. An obj-'ect is to provide a device of this character with which the lure is carried and is moved in a relation to urge the dogs aiong the length 10 of the ra,eing course, and is then removed from the position adjacent to the race course, substantia'lly at the end of the course, to thus remove the urge or incentive for the dogs to continue past the end of the race course. 15 Another object is to provide means to carry a rabbit or other lure in a most attractive and enticing position and relation over and along the racing course of the dog track, which means is movable to permit retraction to remove the rabbit 20 or lure entirely from the race course and frorn a position over or immediately adjacent to the track. Still another object is to provide means within the control of an operator by which the rabbit or 25 lure is moved to the inoperative or non-luring position. A further object is to so construct and mount the parts that when the racing lure has been carried to a predetermined point, and the operator 30 or person in control has set the retraction control, the lure will be substantially instantaneously withdrawn or removed from over the dog racing track, and will be brought to a position out of the line of vision of the racing dogs. 35 Yet another object and purpose is to so construct the retracting means that the lure may be normally carried and moved at a point somewhat ex'tep-ded laterally from the supporting car or carriage, and when the parts are retracted the 40 lure end supporting parts therefor are also retracted toward the car or carriage to thus relieve the overbalancing effect and weight. With the above and other objects in view, which will be appareiit to those skilled in the art, 45 and will appear from the drawings and specification, my invention includes certain novel features of construction and combinations a,nd arrangements and assemblies of parts which will now be described Vith reference to the drawings, 50 and will then be pointed out in the claims.

Fig. 9 is a view similar to Fig. 8 showing the lure carrying arm extended. 20 Mg. 10 is a fragmentary detail view showing the means for holding the lure carrying arm in the extended or operative position. Fig. 11 is a fragmentary detail view of an electricall y energized trip means suitable for use m 25 trippin g the parts as shown in Fig. 10. Wit h the adaptation illustrated in Figs. I throug h 61 the track rails I and 2 are mounted on any suitable support structure, as illustrated at 3, which supporting structure can be carried by 30 posts 4, or other suitable members or structure. The dog racmg course or dog track will be made of any desired size and form, and the track rails I and 2 will be mounted in substantially parallel relatio n to one side of the dog racing track or 35 cours e, to substantially follow the contour of the cours e. A carriage 5 is mounted on flanged wheels 6 and 7, which flanged wheels travel on the track rails I and 2. This carriage 5 may contain or 40 suppo rt an electric motor, or other suitable driving means, by which oi-ie or both sets of wheels 6 and 7 can be rotated to cause the carriage or car structure to travel along the length of the track rails I and 2. As shown in Fig. 6, trolley 45 wires or contact rails 8, 9 and,i 0 can be provided on the track rails I and 2, and contact shoes I 1, 12 and 13 can be provided on the carriage of car 5 to bear against the respective trolley wires or rails. As electrically propelled carriages or cars 50 are well known to those skilled in the art, no attempt is here made to illustrate in detail any partic ular motor arrangement and driving connectio n. However, as three trolley wires or rails are shown it will be appreciated that a current S5

2 2,197,446 control can be accomplished for forward and reverse operation of the carriage or car, and also that electri-cally actuated or other brake mechanism and meaiis can be provided for the carriage or car and can be cont-rolled through one of the trolley circuits as described. Electrically actuated and controlled brake means are common, and also control switches and control circuit arran@ements are well known, in view of which no 1( particwar structure or adaptation is here illustrated. The carriage or car 5 has mounted thereon and carried thereby a supporting case 14, which supporting case at one end has a pivot pin 15, on 15 @vhich a I'Lire carrying arm 16 is swingably mounted. This lure carrying arm is adapted to be swung to a position to extend laterally, substantially as shown in Fig. 1, in which position the rabbit 17, or other lure, is supported and is car20 ried at a distance laterally from the track rails I and 2, and the arm 16 is swingable to a second position in which the arm extends substantially rearwardly from the car or calriage 5 and the lure or rabbit 17 is disposedsubstantially over 25 and above the track rails I ind 2. The arm ID has at its outer end a harness IS, or ot-Tier means by which a rabbit or other lure can be mounfed and will be carried, and the car or carrage 5 is preferably provided 'with a stop or 30 button I 9 which will limit inward swinging movement of the arm 6 and will take up the shock as this arm is swvng inwardly. If desired, this stop or blittbn 19 can be made of rubber or other cushion or spring material, to absorb and relieve 35 iw-pact shocks. The arm fS is preferably curved rearwardly and then laterally, as is best shown in Mgure 1, a.nd a leaf spring 20 is mounted on the carriage and has one end extending to bear against the 4o forward side of the arm 16. A spring latch 21 is provided tb releasably engage in notches 22 and 23 provided on the bearing portion of the arm 16 adjacent to the swinging mounting on pin f5, and this spring latch 21 wiH engag6 in the groove 45 or notch 22 to hold the arm 16 in the extended pgsition, and will engage in notch or groove 23 to retain the @rm in the retracted or rearwardly extending and trailing position. This latch means is so formed that it will resist ofdinary operative 60 forces tending to swing the arni I 6, but that any greater force will readily release the latch so that it can swing upon its mounting on pin 15, A cross supporting shaft 24 is mounted to exterd from one of the posts 4, or from any other 55 suitable support, at a point along the length of the track rails I and 2 corresponding substantially to the end of the racing course of the dog racing track or course, and this supporting shaft is elevated to permit passage of the carriage S. 60 Aii aim 25 is swingably mounted upon the shaft 24 and has a supporting rod 26 telescopically fitted in an elongated opening 27 therein, a spring 28 being provided to urge said supporting rbd 26 outwardly and to cushion shocks due to sudden 65 inw.ard movement of this supporting rod. The supporting rod 26 is bifurcated at its outer end, as at 29, and is provided with bearing portions to revolubly mount a contact wheel 30. A spring 31 is associated with the arm 25 in such manner 70 that it will exert resilient force to normally swing this arm to slibstantially the position shown in Fig. 4, wb.ere the wheel 30 is raised above the elevation of the path of travel of the arm 16 and the spring 20. 75 An electromagnet 32 is mounted adjacent to the swinging end of the arm 25, and this arm has an armature 33 thereon to be attracted by the electromagnet 32 so that the arm 28 will be swung to substantially the position shown in Fig. 5, wlaere the wheel 30 is disposed in position to engage the spring 20 and trip and swing back the arrr. 16, when the electromagnet has been energized. A suitable circuit connection, similar to that indicated at 34, can be employed to sup.ply current from any suitable electric current source, and switch 35 can be included in this circuit to thus permit manual control of the circuit to energize and de-energize the electromagnet 32. The supporting case structure 14 has an elongated opening 36 therein and a plunger rod 37 slidably fitted in this opening 36 urged by spring 38 into contact with the hub portion 39 of the arm 16, where this arm is swingably mounted on the pin 15. 'n-ie hub portion 39 can be pro- 20 vided with a cam formation 40, and thus as the wheel 30 engages spring 20 sufclcient excess pressure will be exerted against arm I 6 to cause spring latch 21 to be disengaged from the notch or groove 22, in consequence uf which the arm 16 25 will swing rearwardly as indicated in Fig. 2. As the arm swings a sufficient distance to bring the cam portion 40 past the end of plunger rod 37, this rod will engage with the cam formation to force the arm 16 to its full rearward position 3u and to the relation in which the latch 21 engages in notch or groove 23. This spring pressed plunger rod 37 serves and acts to aid in holding the arm I 6 in each of its positions for use. As stated above, the trolley wires and con- 35 tact shoes provide means through which the electric motor propelling the carria,e . or car 5 can be supplied with current for eie@er forward or reverse travel of the carriage or car, and also it will be appreciated that this circuit arrangement 4@ii permits provision for relay or electromagnetically operated brake means, or other form of brake mechanism, several of which are well known. In some uses it may be found desirable to provide for extension or lengthening and shortening of that part of the arm 16 which carries the harness 18, to thus permit adjustment and movement of the rabbit or lure 17 to be carried a greater or less distance laterally from the trackways I and 2. V,7hen the arm 16 is swang back the rabbit or lure 17 will be carried substantially over these tracks I and 2, and thus the lure will have substantially disappeared from proximity to the race course, theretoy a,voiding continuation of the lur- 5 ing of the dogs. If desired, a curtain, housing, or other shield can be provided, as at 4 1, in a position interposed to hide the lure when the arm 16isswungtotheinwardposition. Bythisconstruction and arrangement, the rabbit can be 60 thrown to disappear from its extended side position, and thereby avoid the continuation of racing of the dogs. With this arrangement and construction the dogs will not be lured to continue beyond the end of the racing course, and 65 thus likelihood of the dogs being hurt by racing beyond the end of the course, or by coming in coiitact with an extending lure or lure carrying arm, after the lure moving carriage has been stopped, is avoided. With the riodified construction illustrated in Mgs. 7 to 11 inclusive, the supporting frame 42 is adapted to be fitted upon and supported and moved by a carriage or carrier sti-ucture traveling on a track, or otherwise moved along the ex- 75

2,197,446 3 tel'it of a dog racing course, and this supporting fraii'le i-@iight conveniently be mounted upon and c,.trried by a carriage struc@uure similar to the ca,rriage 5, moudted and traveling as hereinbe-5 fore described. This supporting frame 42 has thereon a pivot pin or standard 43, and a lure carrying arm 44 is pivotally and swingably mounted on the bearing pin or standard 43 so that it can be swung to a position to extend lat10 erally from the carriage, substantially os inliicated by the dotted hnes at 45, or can be swung to a position extending substantially rearwardly or trail,',ng from the supporting frame 42 as this is supported on the traveling carriage. 15 This luxe carrying arm 44 is preferably made up as two or niore tubular sections, 46 and 47, telescopically al'id slidably fitted together, and a spring 48 is connected between these two telescopically fitted ti-lbular sections 46 and 47 in suel-i 20 relation that tl-.ie sprii,.lg normally exerts pulling . ,ce to retra-et the section 47 slidably within the .LO @ sectioi,i 46. The tlibular extension section 47 may have a spline groove 49 '(,Iierein, and P- screw or other member 50 is carried by the arm section 25 46 ard is received in this splin.e groove 49 to keep the extension portion 47 from rotati ig with@n the ti.ibular arm section 4f). At the outer end of the extension seet',ion 47 a lure carrier harness or other suppo.-tin,@ means can be provided, as here30 inbefore described or of any other type. The spring 48 n@rmally exerts resilient pulling force to telesccp-Lcslly slide tne extension section 47 into the arm section 46, and a cushion spring 51 is preferably provided within the section 46 3-5 adjacent to the pivot or mounting pin or standard 43 so that as the extensioli section 47 is drawn inwardly sharply under the impetuj of the spring 43, inward movei-.ient will be stopped and will be c@ashioned by this spring 51. 40 As the spring 48 normally tends to retract or telescod.cally slide the extension section 47 into -1 the arm section 46, it is necessary and desirable that means be provided to hold tlae retractable arm port4@on or extens4@On 47 in the extended posi45 tion, wlien the device is in use. Referring to Fig. 9, a catch or latch member 52 is pivotally mounted on the arm portion 46 with its latch end movable through an opening in this arm member 46 to a position to catch against the inrer end 50 of the retractable arm portion 47 and hold this arm portion 47 extended against the resilient retracting force exerted by spring 48. A substantially U-shaped lihk or arm structure 53 is associated with the latch member 52 after the man5.5 ner of a bell crank, and a spririg 54 is prbvided to pull upon the bell cralik lever and urge the latch member 52 into the latching position. Asubstantially U-shaped link portion 55 is s-vvingably mounted on the arm member or laortion 60 46, .),nd has an extension lever 56 projecting beyond the swinging or pivot mounting. A rod or cable 57 is connected with this arm at one end, and at its otl-ier end is connected witl-i the bell crank arm 53 so that as the substantially 65 U-shaped link or lever portion 55 is svtun@.r to exert drawing force u-oon the rod or cable 57, the latch member 52 will be raised to release from its engagement with the inner end of the extension arm portion 47. 70 An arcuate supporting trackway or rest 58 is provided on the supporting member 42 to extend substantially in an are having as its center the pivot pin or standard 43 and serve as a rest for the portion 4ri of the arm, and at its rear end 75 this track or support portion 58 has a hook-like stop portion 53, a lateli 60 being -provided at the throat of this hook-like stop portion to fun4ctioii somewhat after the manner of a snap hook to retain the arm 46 in the rearwardly extending or trailing position. This latch portion 60 can be released manually when it is desired to swing the arm striicture 44 to the laterally extending position as iildicated at 45, and a spring 61 is preferably provided on the pivot pin or standard 43 to exerd force upon the arm structure 44 to lo@ nor-mally swing this arm to the full line positioii as shown in Fig. 7. At the forward end of the arcuate and concentrin. Ily arrpnged or disposed supporting trackway 58, I provide a latch structure to liold the ILre carrying arm in the extended position. This latch structiire consists of a stibstantially Ush,,i,,)ed member 62 which is snvingably mounted on its lower side, as at 63, upon the supporting member (i2. This member 62 is pi,,,otally or @6: swingably mounted at 63 so that the open end thereof is disposed to receive the arm. structure 44 when this arm structure is swung to the position indicated at 45, and a latch portion 64 is provided on the member 62 to engage with a latch pl,@te 6N on the arm member 46. A spring 66 norwally swings the latch member 62 to a position to engage and hold upon the latch plate 65. A rod or pl-Linger 67 is slidably mounted in a silitable bearlng with its rearwardly disposed headed c-iid 68 di,-Po-@ed to be engaged by the arm structure 44 when this arrn structure is swun,- to the position at 45, aiid a spring 69 is provided on the rod 67 to exert resilient pressure to initiate rearward swinging movement of the arm structure 4,4 immediately the latch 64 is released from the latch plate 65, the spring 61 carrying through t-he full movement of the arm structure 44 from the operative to the inoperative positions. The substantially U-shaped latch member 62 has a cam or track portion 70 carried on its 40 upper arm in si-ich relation that a stop or wheel 7 I engaging therewith will depress this cam or track portion 70 and in consequence will swing the latch portion 64 of the member 62 downvvardly against the pressure of spring 66 to re- 45 lease this latch end 64 from the latch plate 65. In Fig. 11 I have illustrated a @convenient means for moving the trip wheel 71 into and out of the tripping position. As here shovrn, the wheel 71 is revolubly mounted at one end of a lever or r)O arm 72 which is swingably mounted at bearing 73. A spring 74 normally exerts pulling force on the arm 72 to raise the trip wheel 71 above a position where it will engage with the cam or trackwa y 70 ' This tripping structure can be 55 mounted at aiiy desired point along the trackway on which tb-e carriage supporting e supporting plate 42 is mounted to travel and the arm 72 can be manipulated to bring the tripping wheel 71 into the tripping position by any suit- 60 able means. Iii the 'Dresent disclosure I have shovtn an electroinagnet 75 adjacent to and above the oliter swinging end of arm 72, which electromagnet can be connected in any desired circuit 65 energize d from any source and controlled by any suitable switcll or other means. An armature 76 is mounted on t-he arm 72 in Position to be attracte d by the eleetromagnet 75, when energized, and consequently the arm 72 will be swung 70 against the resilient force of spring 74 and the trip wheel 71 will be lowered or swung down to a Position where it will come into tripping engageme nt with the cam or trackway portion 70. -vvhen the wheel 71 trips the latch member 62 75

4@ 2,197,446 to release the latch,portion 64 from the latch plate 65, the spting 69 exerts pushing pressure on, the plunger rod 67 to bring the head 68 forced fully against the arm structure 44 and initiate S. rear swinging movement of this arm, the spring 61 carrying through the movement. in the rearward swinging or retracting movement of the arm structure 44, it is desirable that the latch 52 be released so the extension arm 10 portion 47 will be retracted by spring 43 telescopically into the tubular arm portion 46. With this in mind, I provide a roller 77 on the substantially U-shaped link portion 55, and mount a cam track 78 on the arcuate supporting track 15 portion 58 in such position that as the arm structure 44 swings rearwardly this roller 77 will come into contact with the cam portion 78 and the lever 56 will be rocked to exert pulling force on rod or cable 57 to swing arm 53 and raise or 20- release the latch 52. V,7hile I have hereiii shown and described only certaiii specific embodiinents of my inirention and have suggested only certain possible modifications and changes and adaptations, it will be 25-, apprecia-ted that many ebanp@es and variations can be made in the form, construction, arrangement, assembly, and association of the parts, and in the manner of use, without departing from the spirit and scope of my invention. 30 I
