This invention relates to pressingA machines, and particularly to power pressing machines -for garment pressingv and laundry;y

pressin work.

an improved garment pressing.machine h av ing high power ressing mechanism enabling zfa garment to e pressed with great pressiirewithout l on the operators part. y. v ,A further object is to produce an ini- .proved Combination pressing machine pos-` sessing both matically turns on its power to produce final pressure without undue etlort on the'part of the operator, and which machine subscquently opens by power.,

20 springs to lift the press head.

A further and important object is to pro; -Vide an improved press adjustment means whereby the relative' position of the press jaw members, and hence the degree of )aw compression, is conveniently placed under the control of the operator so he. may regul late the pressure on the work, -the ad'ustment means being placed at the front o the press and pressure ress operatingmechanism which isremote .vlfirom the operator. In the accompanying drawings,

50. ress hea 6 is carried on the forward erid Said press lmanual and Apower pressing mechanism, being'a machine which manu;l ally closed by the operator and which auto-v thereby renderingunnecessary the use ofcounterweights or i tut-ing extending to and connecting with ,.other. regulating means included in the Figure illustrates the pressing machine in side elethe press vjawsorhead 6 and -buck 5 l 'provide cooperating press members or jaws l i Anoject of the inventionfis to produce which open. and close in movable relation for purpose of pressing garments.

l Suitable'steamsheating and steam-spra ingthorouglily treated andf'gmeansmay be, provided for either or b members. 5 and 6 for treating the arments.' @A hand-hold' piece, or handle 9,

1a providedvby which the operator manually oth closes the head 6 down upon the buck 5.

The press lever 7 maybe provided'on the rearA endthereof with a counterweight 10 which balances the p ressl head 6 thereby 'prefe'rablyggau'sing the press lever 7 tostand poised atan particular place, which enables the'oper' :to quickly close the head 6 asV down upon hebuck 5. This particular constructionfand mode of operation constipressing machine of this character to be produced without necessarilyemploying springs or over-,balancing weights to lift thehead 6 or open the press after the pressing operation is completed, and thus* I have described the preferred construction as being` so arranged that the counterweight 10 and head 6Hsubstantially balance vo iie with the yA main operating toggle constituting pivotally joined links 12 and 13 is pivoted at its upper end at 14 to the press lever 7 and at its lower end upon eccentric means such as al cam 15 supported in the frame.` The cam is fixed 'to a shaft 16, roller bearing 1 7 -being interposed-between cam 15 and hiiblS made a part ofthe lower-- toggle link 13. A power `andt e tggle link 13 and arm'19 constitute a power .operated bell crank swingable on the camas a pivot.`

'apart of my invention enables a :s so;

The shaft 16 has a worm wheel20 fixed thereto and a worm pinion 21 engages the wheel 20.. A reach rod 22 provided with a hand wheel 23 is fixed to the worm 21,4thereby enabling the operator standing at the front of the machine to rotate the worm 21, which shift-s the cam eccentric element 15 um v of the toggle 12 and 13; and this movement when the machine is o adjustably y pressing members or jaws and 6 thereby rendering the'machine most ellicient -in operation for the various kinds and thicknesses of `,garment pressing work. By turning the hand wheel 23, the cam l15 'may be elevated` or rotated in either direction to= bring the cam upto its higher or lower positionto adapt the press to thinner or thickerfgarmentsf Y A power cylinder is mounted over the forward end of the ower arm 19 and lmay be anchored to the rame 4; and the cylinder carries therein va freely float-ingv unattached piston 26. A substantially soft coil compressionl spring 27 is interposed between the piston and lower en d of the cylinder and functions to return the piston 26 to' its uppermost position. A Vpush rod v29'is pivoterl at 30 to the power arm and has a contact head 31v which is engaged by the piston 26 erati'ng under power. The piston 26 is usua y held in aposition slightly abovethe push rod head, for in designing this pressing machine improvement I have soconstructed it that the manual 33 is connected wit -end of thecylinder vemployed to operate the motor 25--26 may` v operation involved inI closing the head 6l down'upon the buck is carried out-without moving the pistons in the one `or more cylvinde'rs employed,v the object thereof being l to reduce friction of moving parts, thereby rendering the. pressing machine lmore easily closed. Thelower end of the c linder 25 is provided with an open head w ich ermits the ush rod 29 to freely move up an down i in t e cylinder when the operator manually closes the press b pulling downwardly on the handle 9.

A power press o ening cylinder or motor a pipe 34 to the upper 25 whereby the steam be discharged or exhausted therefrom lto the cylinder 33 for breaking the toggle and raising-the head by force of the exhaust from the cylinder 25. The press head liftin motor-33 is fitted. with a piston 35 whic car' ries a valve stem 36 as van integral partA thereof. The stem 36v works back and forth through a cylinder head 37 during the movement of the piston 35'in the cylinder 33.

A soft coil spring BSS confined between the piston 35 and cylin purpose of returning the normal position near the istonv 35 to its 33 is fitted with a-connecting rod in the navaries the relative position of thel er head 37 for the orward4 end -of the cylinder 33 to save the operator moving the piston during the manual closmgistrokm een 1 masa ture of a push rod 39 and pivotal connecting link 45 which has one end pivot-ally connected at '40 the toggle 12-13 and the other end 44 rests in engagement. with the outer endv of theipiston stem 36 of the piston' 35 t-herebyclosing'and sealing a piston exhaust passage 41 without loss of steam pressure when ,thel piston is ushing against the push rod 39-to-lift the 'ead 6.

-However, after the `piston 35v passes beyond certain provided auxiliary exhaust ports 42 in the cylinder, the pressure of steam acting on the piston is' dissipated sufticiently to permit the spring 38 to react forwardly on the piston thereby moving the I iston valve. stem 36` away 'from' the ball eaded end 44 of the push rod 39 which un,- covers the exhaust passagevv 41 and ermits the piston to quickly return to the orward orright hand end of K so w en it comes time .to close the press, the piston v35 has already passed out ofA the Way of all manually operating parts thus saving the operatorseforts, and permitting the push rod 39 to travel through the cyl-` inder head 37 and approach the frontend of the cylinder 33 where the ball valve 4.4 of the rod 39 takes up a position over the the cylinder 33; and

end of the valve stem 36'closing-the exhaust passage 41 'to again make ready for another power o ening operation.

Acus ion sprin forward end of t e cylinder 33? against whichthe piston 35 comes to rest in a manner designed to closely fit the lpush rod head 44 overv the piston valve exhaust passage 41 Wlenl the pressing machine closes, andth'us seal the exhaust 41 so that steam or air n nder. reure entering the motor 33 will positiv y act against the piston 35 to force. the

43 is provide-d atl-the same rearwardly to actuate the push rod '39 U to break the toggle 12-13 to open. the'press jaws. The push rod head 44 performs the' double function of sealing the passage 4.1 and taking the thrust of the piston 35, and the head 44 passesfreely ithrough a central opening made inthe cylinder head 37. It is to be a preciated that this press is manually closed y the o erator only, and no pressing is actual] diene by him, for bythe time the push ro 39 and piston 35 reach the spring cushion 43, the power cylinder 25 will have been automatically turned on to perform thereal work of pressing as will be described.

A steam or air pressure supply main 46 not only supplies steam to the pressing jaw members 5'and 6 but conveys steam to the cylinder 25 as well; and a valve 47 cuts o' and'turns on the steam to operate the motor 25-26. The operation ofthe valve 47 is automatically accomplished" through the agency of a control rod- 48 pivotally connected at its lower end to the power arm 19.

The-upper end of` the rod connects through 'a pull spring 49 with a valve han' dle 50 designed to operate the valve47- with aquick snap closed and snap opened action when tlie power arm is manually worked up and down', respectively. A power control opening pedal. 52 is pivoted on the -frame and connects with an exhaust valve 53, 'ineluded in thev exhaust pipe 34, and this pedal controls the press opening action. Aspring 54 holds the valve 53 normally closed an the pedal 52 up. A link 51 or other suitable means connects the pedal 52 and exhaust valve 53 by which thelatter is opened by the operator to exhaust the pressure from the cylinder 25.

In operation, the press jaws are closed hand power onto the garment spread upon the buck, and by the time the head and buck are in contact, tlievpull s ring 49 is under s'ulicient tension to quic y open the'valve 47 which permits steam to ow to the cylinder 25 and' drive the overtake"-the push ro 29 which action automatically completes ,the operation of` straightening the toggle 12-13 to produce extreme head and buck pressure. A t the same time this movement of parts occurs, the other push rod 39 takes up' a position incontact with the valve stem 36 as hereinbefore described and as shown in Figure 3. Having pressed, steamed,-and dried the garment on the buck, the operator now depresses the pedal 52which discharges the pressure from the cylinder 25 into thecylinder 33 thereby A uickly opening the press by the power of t e exhaust from the power cylinder Aand lifting thehead without springs or weights or manualeort.

In order to avoid undue slammin of parts or too quickly opening the press, t e power opening motor 33-35 isprovided wlth `an air cushion dash ot in effect already l described.l This das pot consists of the cylinder head 37, together with the piston 35 and valve stem 36 which produces an air lock vbetween the parts 37 and 35 when .the piston valve stem'36 moves into sliding fit with the head 37, thus `confining air therebetween under pressurewhich increases rapidl until the movement of parts is stopped against the air cushion. .At this time the uncovered to vent both cylinders 25 and 33 which permits both pistons tomove away from the push rods to the upper and front ends of thee linders freeing the press of any piston or cy inder connections and thussetting the machine -for the next operation. dashpot regulating valve 55 is placed inthe dashpot end of the motor 33 for the purpose of regulating the escape 'of compressed air to quietly bring the head, press lever`l and other parts. to rest in press openedposition.

.It is Idesirable to make power presses opcrate manuallyY as far as closing the press 1s concerned for 1f the closing stroke 1s exv dpiston 2.6 down to.v

ecuted by power, there is dangerof an accident for the operator may by chance get his hands between the jaws of the press. This danger is'always avoided when the operator is compelled. to bringhis hands up to the' handle 9 tofclose the press. The closing o -eration is very easily accomplished for tie press lever is balanced, and there exists minimum ricti'onotmovmg parts. v

The front control hand device 23 for adjnsting the lcompression regulating eccentric means l5 affords an easily `operated press begthe jaw compression' on the work can ,bef-quickly ehangedfa'nd tested and made (more or less at the will of the operator with- -out his moving about or going to 4the rear of the press and without Iinding itnecessary to secure a wrench for' making the adjustment. `The design and-(construction of the mechanism is such that it turns easily from the handle 23. l f

It is seen'that the press operating and presi sure produeing'means 9, 7, 124-13, 19, 2 5- 26 and other parts, include the movable member 13 operatively connectedwith a press jaw and said movable member -13His pivotally carried on the eccentric'pivot support means 15, and that the latter'isshifte a high or low position'in thehub 18 bythe regulating deviceshown here-"by'way of example to comprise'a rod and vhand wheel 23 which easily turn from the front "of the ma.- chine to move the eccentric 15 ,tol a higher or lower position'as desired.- '1i-' In the example of press chosen'toillustrate the principle of theinventio the eccentric .means 15 is disposed at he rear y lower part of thel machine but this elcfeentric is reached by Athe rod 22 which is fitted on the lower end with suitable means to'fifotatably shift and adjust tlie eccentric T15 to finely vary the elev'ation\ ofthe movable member 13. However, theadjustable slip;

port 15 and movable membr\13 carried. thereon, may be disposed at any other co venient location in the press frame.
