This invention relates to brakes, especially but not necessarily, those intended for use on vehicles such as automobiles, and'is illustrated as embodied in a set of such brakes whicli operate differently when the vehicle is roundinz a corner tha@ when the vehicle is run@ ning straight ahead. One manner of! increasing the effect of br.tlces for automobiles and other vehicles, 10 to provide for properly controlling these vehicles in spite of the constant increase in weight and speed,, is by providing brakes on all four of the wbeels. When this is done,, howei,er, at least by t-he -Lise of most of the '@ve are familiar, there is 15 bral@es with which c,reatly increased danger of sIKidding due to loelcing the f rontwheels, which may at times b.e very dangerous in roundin(r a cor I ner. This is for the reason that it i 20 steer the vehicle unless the are actuaII3, tiirniiig, and th wheels are locked the vehicle may skid straight. aliead instead of roundilng the @orner, especially if the road be slippery with ice 25 or by reasoii of a wet avement. In order to avoicl Is da-nger by making sure that at least one wheel wi'[1 ilways be turnincr in rounding a corner, our inventioil conteit@plates the iise of brakes on the steer30 ing wlieels so arranged that one or both *ill be po-,itively disconnected from the brake ee s in ially adva ain s which ha and 35 successful use on the d but wliieh would otherwise ted to exert a coinparatively small retarding force on the front wheel.'s. That is to say, wit,h our invention it is not necessary to ad40 tist the front wheel brakes to apply less reiarding force than the rear wheef brakes, as would other-,vise be necessary to avoid skiddiiig as f,,ir as possible, in aiclaptin(,r for ii-c oii the froiit wbeels n-iost of the types of 45 I)rakes ivliieh are in use for the rear wheels. One form of brake o-Derating connections wllicli is espe@ially usef ill on the front wheels of a vehicle in se@uring the above explained object in@ludes a bralce-operatin(, part and a 50 driver-coiitrolled part which are automatically connected and disconnected simultaneOLISIV with swivellino, movement of the wheel on -,Which the brake acts. Preferably these parts are provided with 6ooperating clutch members arranged to be engaged and disen- 55 gaged by this swivelling movem6nt of the wbeel and which are arranged to engage one another automatically in a predetermined initial position when the brakes are released. One modification of the -invention com- 60 prises a universally jointed brake operating connection supported by the chassis frame, thiis reducing to a minimuin the weight of the iiirisprung parts. This connection includes relative,iy movable clutch members 05 controlled by swivelling movement of the wheel, as for example by a member carried by the kniiekle of the wheel and arrange.d to be moved by swivell' ing movement of the knuckle to wedge the clutch members apart 70 to disconnect the brake when rounding a corner. In the embodiment' illustrated in the drawings this meniber is in the form of a semi-circular slotted cam having a lower portion which permits the clutch members tO 75 on which wedges to disconcorre turn?onding Iii another modification selected for illus- so tration, the driver controred part is mountI ed on t-he axle, and is shown' as being a sieeve slidingly receiving a brake operating shaft the other end of which is supported at one side of the swivelling axis of the wheel, so 85 that swivelling m ve-ment of the w . heel im0 parts an axial component of motion to the shaft. Preferably t-here is a clutch for connectin g and disconnect-ing the shaft and sleeve according to the axial position of the 00 shaft. In the form shown in' the drawings this clutch is in the form of a free wheel ball or roller clutch which normally connects the shaft and sleeve but which in one axial position of the shaft registers -with an internal 95 groov e in the sleeve so t-hat the shaft and sleeve are disconnected. Th e above and other objects and features of the invention, including various novel combinatio ns of parts and desirable particular 100 constr uctions, will be apparent from the following description of two illu'strative embodim ents of the invention shown in the ac'-, compa nying drawings, in w@hich: Figu re 1 is a top plan view. of part of the 105 chassis of an automobi e equil ' )ped with brakes according to the first modification of the.in. vention;

L' '.35 , ][@n the x-odification shoi-vn in -Figui-es I to 4 there is an axle 10 supporting a chassis fraine 12 thro-uo-h the mediuin of springs 14, and to which are swivelled a pair of knucldes 16 oi-i -which are rotatably mounted wheels 18,- eacli 40 of which is provided witli a brake drum 20. Each knuckle .16 carries a supportiiag plate 2@?,, shoivn as beinc- welded thereto, and which supports 9, brake device wliieh may be, and which is shown as beiiio,, an external band 24 45 arrano'ed. to be"contracted aild expanded by a (lei7i.ce operated by rocking an arm 26 conno,oted by t Iiiik 28 to an operating arin 30. The ariii 30 is integral with or secured to the forked end of a sllaft 32 journaled iii a 50 bushiiig 34 carried by the plate 22, the shaft 32 cai,i,ving an outer disk 36 coniiected to the btisl--,in- 34 by a torsioii spring 38 wllicli also @Rrves as a - compressioii spi-ing urgiii,the disl@ 36 toward the left in Figure 2 to liold 55 !he sliaft 32 yieldingly I)tit fii-,nily in place. The idle position of sliaft 32, W'hen the brakes are released, is determined by a finger turned dowii from the disk 36 into an aretiate iiotch in the edge of'the bushing 34. The shaft' 60 32 is connected by a universal joint 40, which is in alinement with the swivelling axis of the knuckle 16, to a sleeve or socket 42 which slidingly receives a shaft 44, the head of which is formed into a ball 46 received in C5 a socket-48 carried by the chassis frame 12. In this manner the shaft 44 is universally supported by the frame 12. The parts described above, @xcept as hereinbefore idoted, may be, and are shown as being, as the same const ' ruction as those de- 70 scribed and claimed in an application of F. A. Bower, Ser. No. 677,001 'for 'vehicle btakes" filed November 26, 1923 and in a pat. ent to C A.. Boom 1,557,969 for "motor veIiieles" dated October 20, 19-95, and whicli -5 are assigned to ti.ic assignee of this applica. tion. , Accoi@ding to tllc present invention the sleeve 42 is foriiied at its end as one iiic@iiiber of a clutch, the otlier mei-nber of wlii(,@li is so forined on the end of a sleeve 50 slid,,ibly mounted on the shaft 44. The sleeve 50 is, constantly urged toward the left in Figiii-es 2 and 3 t;@ a coil spi-in(r 52 engaging a collar or waslier 54 lield by t-he ball end 46 of the s5 shaft 44. An arni 56 integral Nvith or securecl to the sleeve 50 is shown as bein-a slotted to receive the end of a link 58 coiin@cted in in3, suitable iiianner to the bral@e pedal or to any eqtiivtlent cli-iver-controlled device. 90 In order to control tl-ie eng,,igement ati(I disengaueineiit of the eltitch - ineillr)ers 42 in(I liO iccordiiig to the angti ai@- position of the l@nuelde 16, plate 22 is provicied with . a pq.ii, oT f orked lu s 60 connected by horizoiatal 95 9 I)ivots 62 to a semi-eircul,.ir cam member 64 slotted tlaroughout rnos@t of its length -lo striddle the sl-iaft 44 ancl liaving a low oi, tliin poi--Lion sho-wn at the bottai-n in Figure 3 which permits engagemeiit of the cititeli mciii- loo bers and a high or wedging I)ortion shown @it the top in Figure 3 wliieh is thick enough to wed@ze the cluteli inembei,s apart against tlio, resi.@iance of the spring 52. , The horizontrl pivots 62 permit the cain member 64 to swiiig iu5 tip ,ind down -",hen the bral@ie connections inove up and down to I-ollow the i-elatin,e movement, of the cliassis frame 12 anci tl)e axle 10 due to the spi-ing@] 14, but foi,ce tli.e c,@iin to accompany the knuel@le in its i,, @j siviveilin movements dtie to manipulatioii I 9 of the steering wlieel. Thus in the particiil:ir arran(,einent slioivii in the drawings, an.d as.,3uming lat the brtl@e pedal has been depressed, the band 24 will iij be contracted into frictional engageiiient i@-itli the drum 20 as long as tlle vehicie is mol,iii,, sti-,ii-lit ahead or wlien it@is tui-nin(r to the left (Fi-ures 2 and 3), that is when the ivlleel, illustrated iii Fi(rures 2 ind 3 is' the iiiiier l@-,) wlieel. If, however, the steerinwheel is 1-nanipulated wliile the pedal is still depressed to turn the veliiele to the right, the cam iileinber 64, which has its center substantially in the swivelling axis of the knuckle 16, will accompany the knuckle in its movement alid will wedge the clutch ii-iembers 42 and 50 apart so that tlle bral@e'will automatically @)e released. At tllis tirne the wheel shown in Figures 2 and- 3 is the outer wheel. By this 1 -@j

1,711,011 arrangement there is never any braldng ac- are disc6nnected. Th6 outward movement of tion on the outer wheel on a turn and there'is the balls or rollers in this position, as shown practically no chance that this wheel will, in Figure 8, is limited by stops 174. stop turning and- allow the vehicle to skid straight ahead instead of safely rounding the turia. In the particular form of the clutch shown in the drawin,-seach member 42 and 50 has teeth 66 arrati-ed to seat in corresponding de10 pressions 68 in the other member. , As the arm 56 never moves as mucli as 90', after the clutch inembei-s are disengaged they Nv@ill remain di--engaged with t]@@ teeth. riding on the ends of the teeth of the opposite clutcli member, until such time as the brake pedal is released, when the spring 38 and the usual return spring on t,he p6dal will return'All the parts to their initial positions with the teeth 66 seated in tlie. depressions 68 ( @uialess cam 64.) In the modificitio-@i -,Iibwn in Figures 5 to 9 the knuckle 16 carries a plate 122, c6r@esponding to the plate 22, which supports a 25 pair of internal expanding shoes 124 operated @y a cam 126 cai-ried by a short sbaft 132 lournaled in a blishin g i34 carried by plate 122. . In this case, however, the sh@ft 132 does not intersect the swivelling - axis of the -30 knuck)-e .16, btit, as will be apparent from Figures 6 and 7, is spaced -,v short di@tance ahead of this axis. The shaft 132 is formed in its nearest end with a pair of arms cmbracing a universal joint 140, the axis of 35 which is normauy directly ahead of the swivelling axis of the knuckle 16 as sliown in Figure 6. The joiint member 140 is forked to embrace a roiinded projection from a rock shaft 144 to which it is connected by a hori40 zontal pivot pin 146 in such a manni@r as to form, for all purposes of manipul-ation of the brake a second u'niversal joint. The sbaft 144 is slidably received in a sleeve 150 beld in a bearin'ct'- formed, in the 45 upper end of an arm 149 secured to the axle 10. The sleeve 150 is connected by an arm 156 and i link 158 to the bral@e pedal or an equivalent driver-controlled device. In the normal position sitown in Figures ,ind 9, ti-ie shaft 144 is clutched to the 50 5, 6 , sleeve 150, in stich a ii-iainner as to be operated tlierebv, bv iiieans of btills or rollers 166 lield in w,ecit-re'.@liipe(I depre,-zsions 168 formed in tlie. sliaft 144 in sticli a manner as to constitute 53 a "free wliecl," or "Horton" clutch. The balls or rollers 166 are wedged outwardly into clutchin,,,@ en,,a-ement with the sleeve, 150 by their springs 170 in the manner usual with eltitebes of thi8 type. When the shaft 144 is 60 moved axially by the swivelling of its wlieel on the outer side of a turn, as shown in Figure 7, the balls or rollers 166 are, howev er, moved into positioiis whero they register with an internal o-roove 172 formed in the sleeve f),5 150 so that the shaft 144 and the sleeve 150 I n the operation of this modification manipul ation of the brake pedal when the 'wheel 70 is in the position in Figures 5 -6, and 9 will apply the brake by reason of ile' fact that in this position the sleeve 150 is clutched to the shaft 144 -by the balls or rollers 16oo. If, howeve,r, the steering wheel is manipulated to 75 move the wheel to the position shown in Figure 7, the balls or rollers 166 are moved, by the axial motion of shaft 144 due to the forward offset position 6f shaft 132, into registration with the groove 172 to release the -shaft 144 80 and therefore to release the brake. If the steeri ng wheel is again manipulated to return the wheel to the po@ition shown in Figures 5, 6 tnd 9 before the brake pedal is released, the. one'anot her in a new position of relative angular adjustment, so that, if the brake pedal ig further depressed the two front wheel brakes will ?perate differently. When the brake pedal is released, however, due to the 90 "free wheel" constriietion. all of the parts return to their,initial position with the shafts 144 again clutched to the sleeves 150 in their origin al positions of relative angular adjust4 ment. 95 Whi le, two illustrative embodiments of our. inv@n tion have been explained above it is not our intention to limit its scope to these embodimen ts or otherwise than by the terms of the appended claims. i(fo We
