This invention - relates to pressing machines, and pai.-ticularly to power pressing machines f6r garment pressing and laundry pressi.no, -@vork. 9 An object of the invention'is to p,roduce an impr6ved g'arment pressino'machine havina Iiiah power pressin6,, meeliani@m enqblino, I zn ,,.a -arme-ut to be thor6uglily treated . ana pressed -%@ith great pressiire without strain. .10 on the operat or's part. A fltrther object is to produce an improved @on-ibination pressing machine pos-. sessing both m@Dual and power pressing meellanisii-i,.being a machin'e which is manu15 ally closed by the operator ancl which.automati6ally turns on its power to produce final pressure witboiit Lindue effort on the'part bf the operator, and which maelline subse20 unnecessary the use of counterweights o.r sprin,-gys to lift the press head. A furtlier ,ind important object is to pro@vide an improved pr@s@ adjustment means wber,eb the relative- position of the press 'Y In rs jaw embe and hence the del 'ree of j'aw p compression, is conveniently aced under the control of the operator so he. may regulate the pi-essure on the work, ithe adjustment ii-leans bein(y placed at the fro-nt oi the press aiad extendin- to and connectino, with' pressure regulatirti nleaiis fneluded '@in the pre . ss operatino, ine@hanism which is remote irom the operator.

A 50 press head 6 is carried on the forward eiid of a press lever', 7 which is pivoted at 8 on the frame 4 and it is observed how the press jaws or head 6 ancl buck 'provid,e, coopetittiiig press membei@s or jaws which open, And close in movable r,-Ia- 55 tion f6r tb@e purpose of pi,essin(y 0-arments.

The pi@e@@ l@ver 7 may be provided on the rear end theteof with a counterweight 10 which bal,%nqi@s tli6 pi,ess bead 6 thereby 65 '@referab l@,,@a@siiio, the press lever 7 to stand @arr - ]poi@ed di ielll,,ir place, which enables th6 op6tatoi b quickly close the head 6 struction .'a@7,ad mode of operation consti- 0 tut-ing a l@@tt of. my invention -einabl e s a pressing maebine of this character to be produeed without necessarily employing springs or over@balancing m,eigbts to lift the head 6 qliently opens by po-wer thereby rendering@ down up6n, the buck 5. This particular eonor open the pr6ss after the pressing oper- 5 ation is coinpleted, @tnd thus I have desetibed the preferred construction as being so arranged that the counterweicrht 10 and head 6 substantiallv balance oi@7e with the other.' 50@ A main oporatinc, toggle c6nstituting pivotally joined links 12 and 13 is pivoted at its upp6r end at 14 to the press lever 7 and at its lower end upon eccentric means sueb as a cam 15 suppotted in the frame. The cam is 85 fixed to a shaft 16 roller b@aiing 11 being c -nd bub 18 made interpo ed between ani 15 a a part of tlie lower to(ygle link 13. A po-wer arm 19 i$ integral w@ih the togole link 13 "and project8 forwaral@'.-@rom the hub 18; go and. the t6ggle link 13 and anu 19 constitute a poiver.operat@d bell crank swingable o . n tl-ie cam as a pivot.

By turning the liand -%i@l-ieel 23, the cam 15'may be elevated or rotated in either direction to'; bring the 1 (1- cam up. to its higher or lower position,to adapt tlie @ress to tliinnei@ or thicker,, garments. A power cylinder 25 is mounted over the forward end of the pow6r arm 19 and may 15 be anchored to the frame 4; aiid the cylinder carries therein a freely floating unhttiched p;ston 26. A stibstintially soft coil coinpress, on spring, 27 is interposed betweeii the pi@ton and lower e-nd of the cylinder and 20 fitiactions to i-eturn th6 piston 26 t6 its uppermost position. A push rod 29 is pivoted at 30 to the power ai-m and has L contact head 9)1 Nvhich is -engaged by the piston 26 when the machine is operatino, under power. 25 The piston 26 is usually beld in a.position slightly above the push rod liead, for in designin@ this pressin(y machine improvement I have so.- constructed it thit the manual operation involved in closing th6 head 6. 3'3 dowia-upon the buck is carried out without moving the pistons in the one or more cylinders employed, the ob .ject ther6of being to reduce friction of moving pdrts, thereby rendering the pressina machin@ more easily @5 closed. The lower end of the cylinder 25 is provided with an open head which permits the push rod 29 to freely move up and down i-n the cylinder when ihe operator manually closes the press by pulling do-@vnwardl@ on .4C the handle 9. A p.ower press opening cylinder or motor 33 is conbected with a pipe 34 to the upper end of the'eylinder 25 whereby ihe steani e:mployed . to operate the motor 25--26 m,,iy 45 be discharged or exhausted therefrom to the cylinder 33 for breaking the toggle and raising the he,ad by force of the exhaust from the cylinder 25. The press head lifting motor 3@ is fitt-ed. with a piston 35 which car56 ries a valve stem 36 as an integral part tbereof. The stem 36 works back and forth through a cylinder head. 37 during the moven-ient of the pistod 35 in the cylinder 33. A soft coil sprin- 38,,@-'s confiiied betweeii the piston 35 and @@lin@aer head 37 for the pui-p6se of retur-nino, the piston 35 to its hormal Position ne@'r the forward end -of the cylinder 33 to save the operator moving 60 the piston durino, the manual -closin o, stroke and after . the press head has been.Tifted to' its uppermost position by the action of the piston 35, the spring 38 r@t-urns it to the other end of the cylinder 33. Thp, motor 33 is fitted with a connecting rocl in the nattire of a push rod 39 and @ivotal connecting link 45 which bas one end pivotally connected at 40 to the toa-le 12-13 an'd the otber end 44 xe@sts in en(racreme-.nt. with the outer end pf the piston stem 36 of the pis- 70 ton 35 thereby closin(y and sealin(y a piston exhaust p:@issa,@,e 41 ;Tit out loss of steam pressure when the piston is pushing against the push rod 89 to lift the he,,id 6.

A power c6ntrol 0 elriino, pedal 52 is pivoted o the frame p n aiid conr)ects with an exhaust valve 53, iil'cluded in tli@6 exhaust pipe 34, and this pediil controls tb.e pi-.ess opening actioii. A spring 10 54 holds the valve 53 normally closed a;nd meaias conliects the pedal 52 and exliaust valve 53 by which the@ latter is opeiied by th6 operator to exhaiist the presstire from the cylnder 25. In operation, the pres@ jaws are closed by hand power onto the garnient spread upon the buck, ind by e tin-ie the head and buck are in c ontact the pull spring 49 is under .20 sufficient tension to quickly open the valvc@, 47 which permits steam to flo-%v to the cylin-cler 25 aDd drive the Tiston 26 down to overtake' the push ro 29 which actign automatically, completes the eration of CIP 25 straiLThtenin(-y the toggle 12-13 to produce@ extreme he@d and ouck pressure. A,t the same time this movemeiit of parts occurs, the othe'r piish rod 39 takes u@ a position in-contact wiili the valve stem '0'0 as hereinbefore 30 described and as sliowii iii Fi(ytire 3 Haviiig t@- pressed, steamed, and dried ihe garmeilt on the buck, the opetatot now depresses the pedal 52 which dischai@g4e@ the pressure from the cylind6r 25 into the c3,linder 33 thereby quickly o 6ning the press by the pow6r of p the exhaiist froin the power cylinder and liftincy the liead without springs or weights or manual effort. In order to avoid tindue sl,,i'mihing of parts 40 or too qiiiekly opening the press, the power opening,motor 33-35 is'provided with an air cushion d--shpot in eitect alreadydescribed. This dashpot consists of th6 cylinder head 37, touether with the @iston 35 and 45 valve stem 36 Whicli produces an air lock between the parts 37 and 35 When tlie pistoil valve st6m 36 moves into sliding fit with the head 37, thus confining air therebetween under pressure which increases rapidly until 50 tl-ie inovement of parts is stopped a(rainst the .tir cushion. At this time the ports 42 are uncovered to vent both cylinders 25 and 33 which permits botl-i pistons to. move av@,ay froin the pusl-i rocls to the tipper and front 55 ends of the-cylinders freeing the press of any piston or eylinder coli@6ctioiis and tlius seiting the. machine for the next opei,,ttion.
