PRESSING MACHINE.

Application filed June 18, 1927. Serial No. 199,821.

This inventionrelates to pressing machines as garment and laundry presses, and particularly to presses in which the press head is carried by a lever and has for its object a particularly simple and. efficient arrangement of the lever carrying the press head by which a wide opening movement of the press is provided and by which the actuating mechanism 'does not project to the rear-of the frame or the vertical plane of the rearmost part of the frame.

The invention consists in the novel features and-in the combinations and constructions hereinafter set forth and claimed.

had to the accompanying drawings in which like characters designate corresponding parts in all the views.

Figure 1 is a side elevation of a machine embodying my invention.

- Figure 2 is a front view thereof, parts being omitted.

Figure 3 is a rear elevation of the rear leg and parts associated therewith.

'Heretofore in pressing machines of this type, the head has beencarrie'd by a, lever pivoted between its ends so that 'the rear arm of the lever projects rearwardly and pro- 'vision must be made to prevent persons coming in contact with the'movable parts in the rear of the machine.

This machine comprises a construction by which the movable parts are so located that they do not project beyond the rear of the I frame and also so that compression in contradistinction to tension is transferred to the frame at the point the lever carrying the press head is pivoted.

This machine comprises generally a frame, a buck mounted on the frame, a head movable toward and from the buck, a lever carrying the head at its front end and pivoted to the frame, and actuating mechanism connected i310 t(l11e lever between its pivot and the press The frame 1, may be of any suitable form, size or construction and preferablyincludes a. single rear leg 2 having an upwardly and rearwardly extending standard or bracket 3. The leg is in the form of a channel with its channel opening rearwardly.

4 is a buck mounted on thegooseneck 5 which in turn is mounted on the frame 1. 6 is the head movable toward and from the buck; and 7 is the lever which carries the Indescribing this invention, reference is,

heavy pressure to be app head at its front end, the'lever 7 being pivoted at 8 atits rear end to the upper end of the bracket 3.. The lever 7 is actuated by any suitable mechanism connected thereto between the pivot 8 and the head 6. The mechanism here shownincludes a link 9 pivoted atits upper end at 10 to the lever 7 and at its lower end at 11 to a link 12, which link is also pivoted to the frame or to the rear leg in the channel thereof. The link 11 is connected to an actuator as a cylinder 13 having a single acting piston movable therein, the rod 14: of which is pivoted to the front end of the pull link 15. The link 9 has a yoke or fork 16 at its lower end whichembraces the ends of the link 12 and link 15. The link 15 is guided in its movement by a stationary cam 17 carried by the frame, the cam having a slot 18 therein, in which works a follower 19 on the link 15. This cam slot has an upper portion which inclines downwardly and forwardly and a lower upright portion. The follower 19 is initially at the upper rear end of the cam slot and during the initial movement thereof under the action of the piston in the cylinder 13, moves downwardly and forwardly in the upper-portion of the cam slot 18 so that the link 15 acts to move from the dotted line position into the full line position, Figure 1. When the follower 19 reaches the angle in the cam slot 18 the link 15 is moved forwardly at a slower rate but upon a nearly full movement of the piston. The cam slotcauses the head to be closed upon a small movementof the piston and final lied upon a long movement of the piston. The link is bifurcated and the cam extends between the branches thereof and has a follower 19 on opposite sides thereof working in the slots of the two cams.

The links 9 and 12 extend into the channel portionof the rear leg and the link 9 extends through a passage 21 to in front of the bracket which curves upwardly and rearwardly. The motive fluid as air to and from the cylinder is controlled in any suitable manner.

The press is opened by means acting on the lever 7 in front of its pivot 8, this means being here shown as a compression spring 22. The spring is arranged between spring abutments 23 and 24 which are pivoted respectively to the lever 7 and to the frame. These abutments have telescoping portions, that is, the abutment 23 has a rod which slides in a tubular portion 25 on the abutment 24. The spring 22 encircles the rod and the tube. The link 15 is also acted upon by a return spring 26. The construction of the actuating mechanism forms no part of this invention.

Qwing to the arrangement of the lever 7 and the actuating mechanism therefor, the

press head can have a wider opening movement than in the machines heretofore used or Where the yoke lever is pivoted between its ends. Also owing to the arrangement for the actuating mechanism of the link 9, compression is applied to the rear leg instead of strain and hence a lighter rear leg can be used especially when the rear leg is cast iron.

What I claim is:

A pressing machine comprising a frame having an upwardly extending standard, a

buck mounted on the frame in front of the standard, a head movable toward and from the buck, a yoke lever pivoted at its rear end to the standard, means for actuating the lever to close the head on the buck including a depending link connected to the lever between its pivot and the head and springs acting on the lever in opposition to the link to open the head, the springs being interposed between the lever and the frame and acting on the lever between the pivot of the lever and the pivot connecting the link and the lever.

In testimony whereof, I have hereunto signed my name at Syracuse, in the county of Onondaga and State of New York, this 3rd day of June, 1927 I LESTER CHARLES KIENZLE.
