PRESS Original Filed Jan. 28, 1929 5 Sheets-Sheet 3 I ATTORN Patented June 25, 1935 UNITED STATES PATIENT OFFIoE PRESS James Camrod Ledbetter, Jackson Heights, Long Island, N. Y., ass'ignor to The Prosperity Cornpany, Inc., Syracuse, N. Y.,v a corporation of v New York Application January 28, 1929, Serial No. 335,476 Renewed October 3, 1933 produce pressure on the work placed therebetween.

. Among other things, I have produced a'single force applying means for separating or moving one jaw straight away from the other, say the press head from the buck, and also for laterally swinging said head to or from the buck to close and open the press; and as an example of the force applying means there is shown a weight which acts vertically downwardly to separate the press jaws and pulls laterally to impart either a closing or counterbalancing force and movement to the press head and operating means connected therewith. Other force applying or counter-balancing 'means such as springs or the like may be employed if desired.

The accompanying drawings show an example of the invention wherein;

Figure 1 shows side view of the press in open position. I

FigureZ shows a side view of the press in closed or partially closed position with the head just above the buck and ready to be moved vertically into contact therewith.

Figure 3 shows a side elevation of the press head closedover and under compression against the buck.

Referring to the drawings, there is shown a. frame 5 on Whicha, buck 6 is supported and a press head I is adapted to coaot with the buck to press or iron the work placed therebetween. The pressing members or jaws 6 and 1 may be heated in any approved manner, and for both garment pressing and laundry ironing work it is usually the practice to pad the buck 6, while for garment pressing alone the head 1 is coveredwith 'a press cloth to avoid shining woolens; and for 'is' connected with the operating means to aid the latter to undergo a smooth back and forth action to open and close the press which occurs (01. 68-9) when the head is lifted and then carried laterally away from the buck or toward it. A swingable upright 9 has its upper end attached tothe press head. i and in this instance reaches around: the

rear of the jaws for that purpose and its lower end is directed intoothe frame and is pivotally mounted below or under the buck on pins on a cross shaft Iii. A handle I I maybe extended from the upright '51 over thepress head! in convenient reach of the operator in front of thepress to either draw the head forwardly over the work or throw the head rearwardly as the case may be, depending somewhaton the type gof pressconstructed and depending on the characteristics of the counterbalancing or force-applying meansi,

The upstanding swingable jaw carrying memher 9 may be constructed in one single piece or made in pairs and then spaced in parallel relation to each other to guide the relatively long movable jaw back and forth in relation to and from the buck. The movable supporting pivot l inreality possesses a compound motion in that it either rotates or the upright 9 rotates thereon tov swing the head open and closed and the pivot I0 also moves vertically to release the jaw compression. The pivot ID is carried by an operating member or movable supporting means 1'7 under or below the jaws to operatively support the head I and upright 9. V

'-As suggested, a movable supporting member or means 11 is operatively mounted in the press frame, say on a frame pivot l3, and consists of any suitable motoror pedal actuating'means to produce jaw compression. In this example of the invention, the prime mover is a pedal 14 made on a lever arm I5. An upstanding link or armv I6 is attached or integrally joined to the pedaland projects upwardly toward the buck. In fact a bell crank [-16 is formed as the'prime mover or motive means to actuate the press, and an. arm I! is integral with the bell. crank and by, which the latter is pivotally mounted in'the frame for bodily up-and-down and swinging motion. The

arm "affords a compound pivotal or'swinging and Lip-and-down movement, or a two in one motion for swingable upright 9 and'jaw I. Hence the juncture of the bell crank arms l5 and Hi,v defined by the pivot H7 or the upright 9; possesses the bodily two-in-One motion action in question. The bell crank with the arm I! and pivots l0 and I3 form pivot means which carries the upright 9 for pivotal and vertical bodily'movement.

A substantially vertically mounted link His pivotally suspended from the frame on agcross shaft or pin!!! and the lower end is pivotally' con-- upright 9.

hence opening the press.

nected at 2| to the upper end of the arm [6. The parts l6 and I9 constitute an upright toggle conveniently disposed in the frame where it is out of the way and pressure from any source applied to the power arm l causes the bell crank l5-l6 to pivot in the frame and causes the fulcrum pin 10 to move downwardly to compress the head 1 against the buck. The toggle I6-l9 straightens with a powerful force transmitting movement and locks the head down onto the buck. The toggle is, therefore, locking means for holding the head 'in closed position.

The frame pivot l3 and upright pivot ID are spaced apart for the purposes just described and to afford vertical movement for the fulcrum point It! to attain vertical jaw separation or movement.

The pivot includes adjustment meansto vertically alter the position of the pivot III in relation to the frame or press jaws to regulate the degree of head pressure on the buck. To this end the shaft 20 is made on or carries a cam 23. The shaft-20 is journaled in the press frame and when turned by a wrench placed in a notched wheel 24 which is anchored'to the cam 23 and shaft, the cam 23 is of course rotated, and the 'togglelink l9 being suspended from the cam, it

follows that the toggle 15-! 6 is raised or lowered an amount equalto the throw of the'cam. Therefore the compound motion fulcrum in 'or the toggle formed by the links I6 and I9, is-adjustably set to effect the proper jaw compression to be exerted by a'downward pull through the Alocking pawl 25 is pivoted at 26 on the frame and has a spring 21 to keep its head seated in the notched wheel to hold the adjustment.

Theupright 9 is weighted above by the head 7 and hence is top heavy and once started will fall rapidly to the rear and carry the head with it,

Moreover, the rear wardly and upper arched portion 9 of the upright 9 is off center to the rear of the pivot 10 and center of gravity of the head 6 and therefore the weight of the arm portion 9 introduces a rearward gravitational force which initiates-or starts the rearward travel of the head. Balancing, -co'unterbalancing or overbalancing means may therefore be introduced to compensate for the unbalanced condition set up by the weight of the head land the arm portion 9, as dejsired.

In the present instance the portion 9* may'remain predominant so as to open the press by gravity when'compression is released.

A' weight suspension support arm or lever 30 is pivoted in-the frame at 3| and has a loose motion pivotal connection 32 with the toggle IG-l9 say at the pivot 2| of the latter and is adapted to transmit or exert a vertical force or lift upwardly on the toggle and hence on the pivot :IO and on the upright '9 and press head 1 to separate the jaws'after the pressing or ironing operation. A pendulum-like weight 33 is fixed to a pendulum rod or link 34 and this pendulum counter-balancing weight 33-34 is suspended at '35 from the lever 30. Hence the dead weight ="of the pendulum pulls upwardly on the toggle pivot 2| to correspondingly lift the head I and remove jaw compression as the toggle l6-l9 breaks from its straight line locked pressure position. Thisvertica'lly applied force is exerted against the vertically disposed links l6 and I9.

Also there is' provided a substantially horizontal link or connecting means 36 between pivot connecting pins 31 and 38 operatively joining the upright'9' to the pendulum balancing means 33-34.

This link 36 imparts a lateral force to the press head 1 and to its supporting arm or frame 9 to either thrust the head rearwardly from the buck or introduce a balancing factor so that the head I will easily draw forwardly to closed position over the buck. It is seen in Figure 1 when in press open position, that the pendulum weight 33-34 is pulling on the head tending to draw it forwardly, but the force exerted by the weight of the head and off-set or arched portion 9 is a little greater than that of the weight 33 so that the press remains open against the tendency of the pendulum counterbalance 33-34 to return to vertical to restore the press to closed position.

The operator lightly pulls on the handle I I to add just enough force to that being exerted by the weight 33 to overcome the inertia of the press head and any unbalanced weight of the head 1 and upright 9 and start it forwardly, whereupon the operating means I5 is then depressed by foot power or otherwise to straighten the toggle IG-I 9 and lock the jaws together under compression.

Having completed the period of pressure on the work, kick-off means is actuated to break the toggle which is accomplished by sliding the pin 2| in the slot 32 and in this wayv the lever30 is connected to the toggle without hampering the free operation of either the toggle or the lever 30. A kick-off arm 40 is pivoted on the cam shaft 20 and has a side lug 4| which impinges the front edge of the toggle link I9 to thrust it rearwardly. A vertical connecting link 44 extends downwardly and a pin 42 connects each end with its operating elements 40 and 43, the latter beinga kickoif pedal 43. The kick-off pedal 43 is in a low position convenient to an operator and thus works the highly located kick-off arm 40 placed where each other, originate in the one means 33, but

perform different purposes as' is well understood and there is no interference in the applicationof the two forces.

Preferably the pendulum 33-34 never quite reaches the vertical as noted in Figures 2 and 3 because it is desired that a lateral forward pull be exerted on the head even after the head reaches overlapping position with the'buck because that action assures the operator that the head is at its forwardly limited position before he applies the necessary force on the operating member 15 to draw the head down and lift the weight 3 3. The weight of the pendulum 33 is just suflicient to overbalance and lift the head to relieve the pressure between the jaws.

toggle breaks and allows it to straighten to proper position and each end of the slot 32 is a stop for the pin-2|. No other stop is required;

It is significant that the head and upright constitutes an inverted pendulum 1-9 and the force applying means 33-34 is a simple pendulum. The two pendulums are connected together so that they pull against and counterbalance each other. The pendulum suspension points l0 and The length of the 1 slot 32 limits the distance through which the other above its suspended moors-pet are'correspondingly located,"oiie*under and the weight.
