PEEssING MACHINE.,y

This invention rela-tes to garment pressing machinery, and more particularly to im*- provements in high lpressure presses; and has as its primary object that of producing a pressing machine operated, as by foot power, to produce a high degree of compression upon the article being pressed and treated.

i In garment manufacturing plants it is the usual practice to employ high powered pressing machines to shape garments and finish heavy and thick garment seams; and for this work power pressin machines have been devised, as for examp e the machines shown in Patents 1,379,601, 1,386,665 and 1,291,222. These high powered pressing machines utilize electricity, air pressure, or steam, for developing the necessary power for operating the machines at high pressure, and such machines are expensive to manu facture, and entail an operating and upkeep cost which is one of the purposes of our invention to eliminate. Another Patent 1,069,232 shows a pressing machine employing double means for working the pressing members, and it is a manually operated machine, but the arrangement of operating means is such as to not provide a smooth, easy, quiet foot power machine which a press operator can rapidly work by foot power.

It is fitting, therefore, vthat the primary object of our invention is to provide improvements in arment pressing machines to the end that igh pressure is obtained by an operator operation so as to dispense with the use of electric and steam power; and it is also an object to produce a machine simple inconstruction, comparatively inex- 'pensive fto manufacture, one having few working parts, and a machine' which is unlikely to get -out of Workin'g order.

It is also an object to produce an improved pressing machine which has a closing means and high pressure producing means, each of which may be adjusted relatively to the other so as to equally divide, if desirable,

` the total effort of the operator, between the two said means; and to produce a press which opens quietly without jar or strain;

and to produce a press capable of two uses,

namely, edge and seam heavy pressing Aan light finish pressing work.

A A. pressing machine constructed in accordance with the plans of this invention embodies -an arrangement of double pedals with a closing toggle and a power toggle, one pedal being employed to close the press to produce) inltial pressure, and the other pedal bcmg used to produce final heavy pressure on.the garment edge or other object belng pressed and finished; and'in addition, there are improvements in the arrangement of the operating parts, and the provision of features to make the press quietly open and close without undue effort and strain either on the operator or the machine.

The accompanying drawings illustrate one y embodiment of our invention, and though there'is shown one preferredform of construction and mode of operation, we claim a right of protection as to such changes as l obviously come within the scope of the invention.

In the drawings, Figure 1 illustrates a s1de view of a pressing machine embodying the principles. of this invention, the nearV side of the frame being removed to expose the worklng parts. The press is in closed position under initial or light pressure;l

but the press head is shown in dotted lines as being open.

Figure 2 illustrates the press in side elevation, closed under final pressure, with both operating pedals in downwardlyY limited position.

Figure 3 shows a cross-sectional view taken on the line 3-3 of Figure 2; and Figure 4 shows a sectional view taken on the line 4--4 of Figure 2 l Referring now more in particular to the drawings. for a detailed description, there is shown a frame 8 with rear upstanding brackets 9. The frame comprises two spaced frame webs 8 Within which the operating parts are installed to produce a comact machine of refined appearance. The rame supports a work support or buck 10,

and a press lever 11 is fulcrumed at 12 between the frame brackets 9, and on the front end of the press lever there is mounted ,a pressing head 13. Af pair of pedals or levers is employed for swingmg the press lever 11 to close the head 13, followed by d the production of high compression between the head and buck; and the arrangement of the two pedals with link and ,toggle con1 nections -with thepress lever permits an operator to produce extremely high compression upon the work support.

-motion isimparted to the straightened verti- Vvcal toggle 16-f17 by swin ing rearwardly the long vertical arm o bell crank, and

this action produces final high pressure onv the work support 10 Vsubsequently to closing the head 13 on the buck 10. The top link preferably is provided with an adjusting ead or nut 14 which, when turned, varies the overall length of the vertical toggle, to

increase or decrease the closing initial pressure ofthe press head 13 on the work support; and the effort required to push vdown the closing edal is variable in accordance with the setting oradjustment of the nut 14.

A closing toggle comprising links 23 and 24 has its rear end' ivoted 'to the vertical toggle at 25, and its ront end pivotally anchored to the frame on the pin 26; and the arran ement of this toggle is such that when straig tened there is imparted to the vertical ltoggle a straightening action so that the toggles 16-.17 and 23-24 approach av substantially transverse position one to the other. A closing or initial pressure pedal 27 is pivoted in the frame on a pin 28, and the pedal has a foot piece 29 by which the operator depresses it. This pedal is connected to the closing toggle 23-24 by a link 30. Thus by depressing the pedal 27 both sets of toggles, as aforesaid,'are straightened .to close the head onto the buck.

A high pressure toggle is employed to actuate the bell crank 20, and consists of links 32 and 33, having their adjacent ends pivoted together. The rear link 32 is connected to the bell crank at 34, andthe front link 33 is pivotally anchored to the frame as order that the position of t on the pin 26. The 'link 32 is adjustable, and is constructed in the form of a threaded rod which may be rotated to slightly vary the overall length of the toggle 3,2;33, in

e bell crank may be slightly altered to vary the final conmpression between the Lhead and buck.

.A -high pressure lever or pedal 36 with foot piece 29 is ivoted inthe frame,.as on the pin 28; andl 'a link 37 connects this pedal with the high pressure toggle 32-33. When thisv pedal is thrust downwardly the toggle is straightened to force rearwardly the 4long arm of 'the bell crank which lifts the vertical toggle "through a short distance to im ose additional force upon the press lever and head to increase 'the compression between the pressing members 10 and 13.

Thus it is seen how the first pedal 27 is depressed to brin the pressing head into engagement with t e buck; and b pushing the other pedal 36 to downward y `limited position, the press lever 11 is moved slightly on the` fulcrum pin 12 to impose additional high pressure on the buck 10. The link 37 may be turned to adjust the relation between a pedal and its respective toggle, so that When the edal .is in downwardly limited position, t e toggle will have reached a straight line and lockedposition so as to maintain this place under pressure.

A release or kick-off device in the form of a pedal 39 is pivoted at 40 on the frame Vand has a rear li ting end embodying a high contact surface 41 and an adjacent low contact surface 42. The rear end of the pedal v39 is disposed directlyvunderneath the edals `asimilar u ward thrust thereon; and it is seen, there ore, how, when the operator steps on the release pedal 39, the two operating pedal levers are, one at a time, forced upwardly. And in this arrangement, the lhigh compression is first'y spent or dissipated, followed immediately by the lifting of the head 13. It is desirable to thus arrange the kick-ofiI pedal 39 so that the stored up energy .and pressure is gradually spent or dissipated las, distinguished from llfting the press head 13 before the press gains relief from the high pressure.

A pressing machine of this type which works under abnormally high pressure necessarily requires' means for absorbing the shock of the moving parts in order that the machine, will not be.- subjected to strain when coming from under high pressure; and to accomplish this purpose, an air cushion device is employed which comprises a dash pot 44 pivotally anchored at 45 to the fra-me; and a connecting rod 46, with a piston confined in the cylinder, is attached to the high pressure pedal 36.- The compression of the air confined inthe cylinder imposes yielding resistance to th`e upward thrust of the pedal and thus absorbs the shock of the suddenly moving parts, so that the release of the machine from high pressure isV accomplished quietly and smoothly without noise or damage to the mechanism. A coil spring 47 is applied to each pedaLto lift and support it 41n uppermost position;` andto this end the object tobe pressed, over the surface of the' buck, and then thrusts ldownwardly the closing pedal 27. This action bringsboth togi` 1,669,633 a l 3l gles 23-24 and 16-17 into straight line position which swings the press lever 11 and engages the head 13 onto the garmentunder initial closingpressure. T pushes downwardly the high pressure pedal 36 which straightens the toggle 32-33 andy forces rearwardly thebell crank arm 20 to lift upwardly the vertical toggle, and this action imposes additional pressurefon the head 13 to produce a high degree 4of compression against the object being treated andv pressed. To open the press, the pedal 39 isv thrust downwardly, which .first kicks off the pedal 36 to break the high pressure toggle 32-33/ and thus slightly lower the vertical toggle 16-17, which action releases the machine from high pressure. `The dash pot 44 absorbs the shock and strain as the pedal 36 swings upwardly. As the kick-oil pedal 39 is forced further downwardly, the pedal 37 rises'to break the closing toggle 23-24 which swings the lever 11 and lifts the head off the work.

Inasmuch as two pedals are rovided for producing the extraordinary 'high pressure, it follows that the effort or work done by the operator may be beneficially and equally divided between both pedals so that one pedal operates under about the samerexerted effort as the other. If desirable, the operator can adjust the initial closing pressure by turning the nut 14 so as to make the head 13 close very easil and thereafter it is necessary .to rotate t e adjustable link 32 untilthe high pressure toggle is made considerably longer l in order that the bell crank arm 20 may be forced further out to the rear to lift the vertical toggle somewhat higher to impose off the garment and impart to the fabric a refined nap raised finish. It is common ractice to employ two presses for this work so that the heavy edge pressin is done upon one type of machine and the finish pressing is done on another machine. A particular advantage of the present invention is that it provides a two purpose press which can be used for both aforesaid purposes; and to this end the operator ma use both pedals to do heavy edge work, an thereafter use the closing pedal to do light finish pressing Work.

This machine embodies specific advantages over various other types of high powered edge presses in that it produces as much he operator next pressure as motor and steam operated machines without the cost of upkeep and power:

and without the great fcost .of manufacture of motor driven and steaml powered pressesA` In additionto the above, this pressing ma' chine is simple to operate and is unlikely'tol getfout'of working order because lof the absence of-eleotric controlmechanism, or steam.
