Patented Aug. 15, 1933 19922@052 UNITED STATES PATENT OFFICE 1,922,052 GARP4ENT PRESS Jaines C. Le,,@,better, N. '17., assignor, by r@'lesne ass to The Prosper',ty Com,nany, Syraciise, N.-Y., a corporation of New Yc;rk Appli,@ation Apr5l 26, 1921. Serial No. 709,147 2,0 01,11T.-.is. This invention relates to p,-esses and particularly to garrreiib presses aiid iroriii.- machiiiery. A main object of the inventioii is to prnduce a press capable of being closed by hatid follo,7@ed by application o-f high pressure and ,vhicii does not have the usual wide open-ing 4aws or high lifting head wi-th consequen' . dange-r to the hands of the operator, but at the stm,- time rny improvement provides -@ea,,er visibility of -oressiiar@ surface upon which the Nvork is spre,,td th,,@n roodern pressing machines now in use, and i-s @-o constri,icted that, in opc-.ain.- up, the pressii-ig members or iaws do not uiadergo the usual angu1--ar jaw action but slip apart lateraily and 4:o16 gether olit of and L-ito overla,.oling posi@@-lon out at aiiy time perr@littin,- the operator to get hi-s fingers in betvT,,e-.-i the pressing merrbers because in fact my pressing rieinbers p-.rt o-.@ ouen into exposed positi-on to permit the rem.@val anc','- 20 repiaceme-Tit of the wo-,k upoii a fully visible I)u,,@k prefera'@-)Iy viithout allowin,- any Trore than st,,intially a fraction of an inch clearan-le between the head and bu-,k, a--id so an o-oc@"ato--ca,Tinot possibly -et his fingers in between such 25 swall jaiit clearance as this. Fui,thermo,.-e, an object is to simpli-fy the constru-.t-iol-.,, of pressina machines and I acco--@np.Lish this ii or.Le w,.ty by e'iiminat-il'lg sue.L-. frequently us(-,d parts a@@ the toggle, counterbal@a@ice w-lig',It, 30 aid press !-ever yoke. i\,Iy ii@-proved pressi@ng chip-e possesses a press head which itself is the counterbalance weight because i eiaiploy the principle of an inverted peidulu-ni aiid so pivotally mount the press head in the frame 1-lhat it stai?,d-, -5 iii po4sed overbalaiieed posi-tion acted on by @rq-v@ity and ever ready to th,@.,ow itself bodily off the bup-k when the cow..-oressioT-i i-s released. By elirf.- inatin.- the uarts named the press l@?ss w-aterial and is lighter in weight and smaller in 40 size. By rneai-is of a compouiid motion of o-ae or both pressiiig merilbers rriounted on a compolnd-motion pivot whereby they unde-@-go slighf vertic2@l sepai-ating clearance rpovement automatielly fol45 low--d by a rapid rectilinear or Igteral travel, the press is caused to open wide for accees to and visibility of the work on the buci,,, and yet at the same tiiyie the pressing meinb@-rs are not permi-tted to onen up by seoarat-lon and tlierefore the op50 ei,,,itor cannbt possibly get hi-s fingers pire'aed iii the prcss; and there@Loi,e iny pressitig i-@iachine i-s safe; i.ts pressing buck is not partly covered by ar, angulal-ly poised press head standing iii the oderator's way above the buck as iii t-he A-.idree 55 Patent 1,379,601; and I find no need of e..apicy(Cl. 68-9) ing coinplicated "main or stipplemeiitary controllinr.-ieans" w-th an effort to make a press s,-,fe as ii-, the Benjamiii & Carroll Pateiit 1,489,227 because my press is inherei-itly safe. The characteristic compouiid r@iotion (latera;i and vertical) for the press head is atta-ned by a co-n-ipoundmotion pivot carr-led in the fraine, the pi.vot being capable of a rotary -@nd up ap-d down ,iiotion; and the pivot is p-laced scbstentially in a vertical plan,- passing th-,-,ough the press blick. 65 The accompa.-iying drav,7ing ilustrates one practical. f orin of the construction, and it, i-S unders4loo@l how cha-7i.-es both as to structure and mode of ma . y be made witl-iout departing from the pr@,ncii3le of the invet-ition. 70 !Pi @yul,c 1 is @- side vie-.,v of the machine; and liligLIre 2 is a fro-(it vi,-v,7 therebf with the exception that a part of Figure 2 is developed on the 2--2 of Figure I to remove the motor to expose rdore essential parl@-S in @the froht view. 75 F,' @gure 3 shows a sectio-,ial vie@v on the line 3-3 of Figur-, I i-liu@,trating ar- adilistable lever formi-la part ol the motor power rneans operatii@g to br,@'ii g the pressing members tbgether and separatin-, them by imparting @vert-',cal niotion to one 80 or both of the pressin.- -nembers. Ref err-iil," no-,li @,.iore paz@uicularly to the drawino.- L'or a det,,),iled description of the iiivention, there is shovm- a m. -achine frarne 10 upon w'@,iieh one of the pressi.ng jaixr members, as the buck 11, 8,5 iray).)e rigidly supported. i A press head 12 coacts with the bucic 11 to produce jaw compression th,-rebetween o,.a the work; and the head 12 13ossesses a compound. or double motion in that th-. said head 12 firs@ ri es through a very short go u s dista-ice, as for ejample, about ore-eighth of an inch,of-,L the N@Tork, ap-d thereafter tlle said head throws itself backwardly off of the buck 11 to t,-Tie dotted line position shovin ;@n Figure I whereby the buck 11 is uncovered to fully expose the 9,5 surfgce of the bucir- @uo give access to the worl@: the,,-,eor, as v7e!l ,),s ext,@,nded visib,ility. By noting the dotl@-ed line posi.tion 12 of the head, it will be apprec-lated how, in my present machine imrrovements, the head is not left in an angular loo posi-tioyi above the buck in the way of the operatoi: as preseiit-day so-called modern type large s,,irface wide opening pressing mochines, but the licad is re-moved eiitirely from the region of the buck; and it will be u-@iderstood later on just how 105 this irrproved -,'eature contributes to safety as ,,7e!l as to visibility of the v,7ork. The pressing members 11 -)nd 12 are heated electrically or by steam or any ol@ the kriown approved me.ans. An upri.-ht pull Iiilk 14 is anchored to the top ]@ip

2@ 1,922,052 of the head 12 and curves rearwardly around the back board 15 of the pressing machine table 16 and rearwardly of the bucl,, 11 extends downwardly throu.-h the frame underneath the buck 11. T-Iiis s-vvin-able-uDright head-catrying frame link 14 may in fact be constructed by employiiig two of the links mounted in spaced parallel relation, as shown in Figure 2, in order that the head 12 be attached to the swing element 14 at two 10 separated poiiits so as to provide a well balanced and gli-ided movement as to the operation of the head. The upper e-,ld of each spaced swing link 14 is anchored, as at 17, to the head 12 and thus it will be noted how the head is held in slidable 1,5 alignment so as to slip back and for'uh in very close relation to the buck 11 without disarranging the work on the buck ' The lower end of the upright swing Iiilks 14 cooperate w-ith or are pivotally connected to@ a co20 operating means or power lever 19 made, in one form, with pa-i:allel spaced and rigidly connected parts in the nature o@@' @l bifurcated lever as@shown in Figure 3, and a p;in 20 pivotally joins the lower end of the upright swing l,.nk 14 with the said 25 lever 19. The head 12 is therefore pivotally suDported to swiiig about the point 20, and in the present disclosure of my inveii'Lion, i have showii the pressing metnbers 11 and 12 as having coacting arcuate pressing surfaces 13 which may 30 be made eacb. conce--,Itric with the axis of the co,-npound-motion pivot 20 4uhereby permitting the head !2 to slip easily and naturally into overlapping position with the buck 11. However, the curvatiire 13 of the meetiiig p.,cess surfaces is 35 itnmaterial a-,id the -,oressi-pg or ironing faces of the two members LI a-nd 12 may be flat or curved 'uo any degree desired, Th-- lever 19 in having spaced and rigidly conrected parl@s, insures a more accurate aligiipient of the head aid buck when 40, they con,,e togetl-ie-,@-- for pressing engagement. u ' the power bil'urcated lever 19 The fron' end o.L is adju8tably si-lpported on the fra@-.ie 10 for thb purpose of adjusti3ig the cor.- @pound fulcrum point 20 up and.down throu,@h a short distance to 45 increase or decrease the clearance sdace b--tween @he pressi-,ig mei-@ibers. To tliiis end a shaft 22 is journaled to rotate on each eild thereof in the fra-(ne 10 as at 23. The sliaft 22 carries integral oT fixed cams 24 ro'uatcbj'.y mou-.q'-b.-d in the 50 front ends of the. lever 19, and the arrar..@eme-@it is such that when an adjustment crank 25, w ch is integral wi-th the shafl@- 22, ;@s swun,a ,ibout its center, the said cams 21 are rotated to depress or ele-vate this end of the lev@Ir 19 which corre55 spoiadi,,igly moves the fulcrum pin 20 tl-iereby raising or IoNvering the press head 12 in relotion to the buck 11 so as to adjus@@ or regulate the clearance betweer@ the pressing su,2faces. A handle 26 is made oT-i the crank 25 and the handle 60 is-provided with I a 16ek pin 27 wl-i-ich goes in and out a perforated lock plate 28 en-rried on the frame 10 ' The lock pl-,Lte 28 is provided with a plurality of lo@,k adjustment holes 29 in whi@-h the pin 27 engages by shovin.- inwardly on the 65 handle 26. The handle 26 with its lock pin 27 and plate 28 permits an operator to quickly alter the position of the cams 24 in order that more or less clearance be had between the pressi-ng memb.Irs 70 11 and 12. Tt is seldom necessary to alter the adjustmenlu in ironing machines inasmuch as they are usually devoted to the pressiii.- of wash goods whibh do nbt vary greatly i-ii thickness, and therefore af@@er th@- povjer lever 19 is on,.e properly 75 adjusted to provide about oiie-eighth of an inch clearance between the pressilig members, it follo,,vs that the machine will be used to a large extent without changing the pressing surface clearance space. The rear end 30 of this adjustable power press lever 19 cooperates with 80 motor power riieans for imposin- high jaw. compression between the head and buck as will be seen. A spri-ng 31 has. one end thereof supported on the frame with the upper end placed uilderneath the free end of 'uhe lever 19 thereby exert- 35 ing a continual upward thrust on the swing link 14 to hold the press head 12 in upwardly lim-ited position away fi:om and slightly clearin.- the pressing surface of the buck 11. l@Iowever, the spring 31 readily go-,s down under the ap,,olica- 0,0 ti-on of final py.-ssure by the motor means, yet always returns the lever 19 to its normally upivard position at the end of the corf-,i)ression and r8lease stroke of the head. Any suitable motor power means is applied gri to the outer free end of the -cower lever 19 for moving it downwardly under great force through a short distance; and in the. present instance I have shoivn an electrical motor and gear train employed 'Lo actuate the power lever 19, but it is 100 understood that this particular motor means is Mployed only for illustrating my invention@ A cam 33 is carried on, a shaft 34 which is motor driven, and the cam-33 bears up and down on the i-,ar end 30 of the power lever; and when the i Ci5 cam is do-wn, the spring 31 compresses, but@when the cam. 33 goes up the spring 31 expands to lift he press head 12 and hold the lever 19 in contact ,vitil the rbtating cam. A worm wheel 35 is a.,ichbred to the power shaft 34 and is driven by 110 2. woi7i2i pinion@ 36 connected directly to a motor 37, aiid a fly vjheel. 38 is usually carried on the rdotor shaft 40 to impart momentum and produce '-@, st--ady continuous drive with an even flow of -oower to the cam 33. The gear transmission 35 115 and 36 and other parts related therewith are carried in a housing 41. The requiremet-its of garment pressing aild laundry ironing machines are such that the pressin.- period varies. It is desirable therefore that 120 me,-ns be provided for stopping and starting the -am 33 in order that the heed 12 be compressed Liporr the buck for a period depending iipon the will of the operator ' In some cases a stop and. ,tart --'n-@tOr 37 is employed whereby the motor 125 is sv,7itched on to, rtin until the carn 33 rotates 131-1 degrees to produce- final pressure or relieve it, a@nd 'hereafter the motor is usually cut off automatically thereby leaving the pressing members under high pressure. But in the present 130 disclosure, I have illustrated a continuously running motbr 37 with an automatic clutch and re"-easing mechanism o-f any approved design whereby the cam 33 is turned one-half revolution and th.-n automatically comes to a stop. For example, 135 a clutch disc 42 is mounted to reciprocate back and forth on the shaft 34 to engage and disengage the continuously running worm gear 35. Inasmuch as the gear 35 is journaled ireely on the shaft 34, the said cam 33 is not rotated until @IC the clutch 42 is thrust toward the worm wheel 35 to engage the driving pins 43 with the worm wheel 35. A clutch lever 44 is pivoted at 45 in the housin., 41, and when the clutch 44 is swung to the righ'Ll, observing Figure 2, the clutch functions to st,-,rt the shaft 34 and after the cam 33 is driven oi-ie-half revolution the clutch automatically releases perrnitting the cam to stop under high com@ pression as shown in Figure 1.

Any ;@,,a;@ta,ble pe-,7ier clutch --,neans, or stop and start .motor, may be emrloyed to rotate the cam 33. I The link 14 may be pro-,7--lded with a cross @oie bar @9 -@7,Ti-th a buinper sprin.- 50 anchored to 1.5 the -rear thereof and a comoressing automatic bi,.,,,o@v-off spr-l.np@ 52 Lnehored to bhe frop-t side o-f the bar 49. The s-ori--,ag 50 acts to seat back agq-inc@t a stop 53 whe--,,i the -oress is opened to pr-vent r-,oise -iiid ja@.-ring o-f the machine. The 20 coiiqpressioii 52 noves forwardly agairist a buffer 54 -,nchored on the front of the frame 11 ,,). Tie sp-,-iiig 52 -is relativel@y short and hi.-hly co.iii-cressible so that it only resists lightly the c'lo,,zing motion of the head. As the operator 25 draws the head 12 forwardly, the spri-ng 52 finnlly n,ieets the face o-f the bui-ier 54 and as the head 12 is l@ulled further forward the sprit-ig 52 becor,,,es coiiipressed. just as soon as the operator dt-presses the power --pplyinp,, handle 46, ,the r i n - Q_ 52 beco@rI7,e:,3 @lyieficetii7e to open the press be caiise the press s tightly closed.

Tt is to be noted that the fulcrum -ooint 20 is preferably "@n vertical aligiament, or approximately so, wi-th the mean center of the pressing members, aiid thqt the swing link 14 is pivoted s7Libstanti-fl!ly in a v,-rtical position with the v,7eight of the head 12 poised above all the other part@, o-c the pressing machine, vvhi@-h cor@stitutes a st@@uctui:e iiot uiilll@,e an inverted pendullim having its ce-,il,er of gravity high above the pivotal po-int, the--reby produci,.ig a Dress hen-d -,,i7hich is s-@,,7ing,).bly qustqired on a pivot disposed unde,.L'he bu,-k 11 a,.)-d the head easily moves back aiid orth ov.-r the bue,- and no counter balaT-ici3.1-g --eaqs is real-ly iieedecl to balan@ -e the head. The 7 'he pivot 20, whether it is towaid the posi@ bil.n of u - ii.,--nt or rear of the press, deter,-.uiiies the balanciiig cha3:acteristi-cs of the head ,,,i-id the uD@@,@ht II,,!, or head supportin.- frame 1,1. Ho@i,,ever, the curved pos-L of the sv@ing link passil?g ba@-k of the tq-b'ie throws the center. of gravity slightly off-center and so the head may 't.,e re@terred to 9,s slightly over-balarced be-@w@ise i may prefer it this way so as to obtain , quick o,oen-ing movemer-t. Because the swing link 14 cirves around to the rear of the press jailis to clear the tpble --nd the other parts, as aforesaid, it folilows that T have placed the center of gravity sl@ightly to the rear of the head 12 thereby settit-ig Tip a co,,itiruously exerted backiliard pull on the head of the p.-ess. This over-balai-.cing -fa-eto-,, ca,,ises the head 12 to q-Liiekly execute a ,@earward motion when compression is release d ,,,nd it therelore is not always necessary to employ the throw-off spring 52. It will therefore be a,,opreciated that this press-ing machine is constructed witholit w.-igl-its or toggles to open the press@ The press head 12 itself perforins the funct-lon of the counter-balance weight which is so prevalent in the art as well as elir.,iinating the no.-essity o.E springs, so iaeither the weight or spring is required.
