A TT ORNE Y5 Patented Feb. 14, 1933 UNITED STATES PATENT OFFICE ERNEST DAVIS, OF SYRAGU SE, NEW YORK, ASSIGNOR TO THE PROSPERITY COMPANY, INC., 03 SYRACUSE, NEW YORK, A CORPORATION OF NEW YORK PRESSING MACHINE Application filed April 19, 1926, Serial No. 102,872. Renewed May 2, 1930.

This invention relates to pressing machines and has for its object a pressing machine, which is particularly simple and compact in its construction particularly in regard to its 5 frame and the actuating mechanism for the head, and which is also highly eficient and durable in use and can be placed on a bench or other support and hence does not require afspecial table built as an integral part there- The invention consists in the novel features and ,in the combinations and constructions hereinafter set forth and claimed. g

In describing this invention reference is 15 had to the accompanying drawings in which like characters represents corresponding parts in all the views.

Figures 9, 10 and 11 are sectional views taken respectively on lines A-A, B-B and CG of Figures 6 and 7 Figures 12, 13 and 14 are, respectively, a plan view, a side elevation and a front elevation of the casing for the base.

This pressing machine comprises generally a base in the form of a housing, the base having an upright rising therefrom. a buck mounted on the base, a head movable toward and from the buck, a lever for supporting the head pivoted to said upright and having an arm extending lengthwise of the upright into the base, and mechanism for actuating the lever connected to the lower end thereof, said mechanism being located within the base. The base is of such form that it can be readily mounted on a table or bench and house 50 the actuating mechanism for the press head,

and also act as a support for such actuating mechanism.

The base 1 comprises a lengthwise central portion 2, having an upright standard 3 at its rear end, the lenghtwise portion 2 being in the form of a box. The base also includes laterally extending portions 4 upon which the bracket or goose neck is mounted which supports the buck. As here shownthe base is made up of right and left halves which are welded or otherwise secured together and the uprights of said halves when assembled form a channel which is open at its rear side.

5 is the buck mounted on a goose neck 6, which in turn is mounted upon the base 1 or the laterally extending portions 4 thereof.

'A. head 7 is movable toward and from the buck 5 and is carried by the upper arm of a lever 8 supported between its end on a shaft 9 mounted in bearings 10 at the upper end of 70 the upright 3, the lever having its lower arm 11 located in the upright standard 3 and extending into the base.

The lever is double and in the form of a letter C so that the end of the upper arm"? which carries the head '7 overhangs the buck, and the end of the lower arm 11 extends downwardly and forwardly into the base, in open press position. The base is mounted upon a suitable table 12. The lever 8 is in the form of a frame or yoke as seen in Figure 2.

The actuating mechanism for the lever is for the most part located within the base and 7 that here shown comprises a cylinder arranged horizontally in the base and preferably extended forwardly and rearwardly in the lengthwise portion 2 of the base.

13 designates the cylinder and 15 the piston and piston rod movable in the cylinder, the piston having a sleeve 16 connected to the outer end of its rod, which sleeve telescopes with the cylinder so that the cylinder acts as a-guide for the sleeve 16 and the sleeve serves as a cross head. The sleeve or cross head 16 is connected to the lower end of the lever 11 by any suitable means as links 17 pivoted at 18 to opposite sides of the sleeve or cross head 16 and at 19 to the lower end of the lever 11.

The piston 15 may be actuated in the cyl- 1 inder by any suitable means, and in the illustrated embodiment of this machine; it is shown as operated by a fluid under pressure which is supplied thereto by a pedal device,

5 conveniently located and connected to the cylinder.

The device here shown is a pump having a piston 23 which is operated by a pedal 21. The pump is here shown as including a bell0 lows 21a located within the suitable housing or cylinder 22, the bellows having the head or piston 23 at its lower end which is connected by a connecting rod 24 to an angular or rock arm 25 mounted on the shaft 26, the l latter being actuated by the pedal 21. These parts are all suitably mounted as a unit in a frame 27. The bellows chamber or cylinder 22 is connected by a pipe 28 to an inlet cham ber 29 for the cylinder 13. This inlet cham- 20 her is provided with a suitable valve 30 which is pressed toward thegport or seat 31 by the pressure generated in the pedal device 20 and is provided with a handle 32 by meansof which it can be manually tripped to release 25 the pressure in the cylinder. The handle 32 may be raised manually to close the port 31. The chamber 29 is also formed with an air vent 33 to prevent the chamber from becoming air bound. The pump or bellows chamber 21a forms also a second reservoir for providing fluid to the cylinder 13 and particularly fluid under pressure.

In operation the operator may close the press by pulling down on the handle on the 35 head 7 and thereafter stepping on the pedal 21 to apply final pressure. When so closing the press by hand the piston 15 moves towards the outer end of the cylinder 13 and the oil flows from the chamber 29 through the port 31, into the cylinder so that the cylinder is filled with oil. Hence upon the depressing of the pedal 21 to apply final pressure, such pressure will be applied through the cylinder 22, pipe 28 and cylinder 13, the pressure in the pipe 28 first closing the valve 30 against its seat 31.

In pressing clothes, the operator varies the pressure to suit the conditions in pressing diiferent portions of the garment. In my machine, the pressure can be varied to any degree. For full pressure, the operator pulls down the head to close the press before stepping on the pedal 21 and the oil during the pulling down of the head follows behind the iston from the chamber 29 so that the cylin- Ser 13 is full as is also the bellows 21a and when the head is closed a full throw or leverage of the pedal 21 can be given directly against the oil which completely fills the cylinder 13 and the bellows 21a. For less degrees of pressure, the operator pulls down on the head and before the head is completely closed also steps on the pedal 21 thus closing oif the flow of oil from the reservoir 29 to the cylinder 13 so that the oil feeding behind the The head 7 is caused to open by a counterbalancing spring 35 suitably arranged to turn a reel or barrel 36 on which winds a cable 37 which is connected to the lever arm 11. During the closing of the press the spring is tensioned and when the pressure tending to hold the press closed is released thespring acts as a counterbalancing weight to actuate the lever 11 to raise the press head 7.

The base may be covered by a suitable cover or finishing plate 38 stamped of sheet metal and having portions 39 to cover the standard as well as portions to cover the base proper, this cover plate being held in position in any suitable manner. The cover is stamped from sheet metal and the parts thereof riveted or otherwise held together and the function of the cover is merely to serve as a finish for the base.
