GARMENT PRESS.

Application filed February 18, 1920, Serial No. 358,924. Renewed December 16, 1921.

To all whom it may concern:

Be it known that I, ARTHUR E. Sxow, a citizen of the United States, residing at Norwood, in the county of Hamilton and State of Ohio, haveinvented certain new and useful Improvements in Garment Presses, of which the following is a specification.

This invention relates to pressing machines. The object of the invention is to provide improved mechanism for actuating the relatively movable pressing members and particularly to provide improved means for producing final heavy pressure between the pressing members additional to what is ordinarily obtained by actuation of the foot treadle.

A further object of the invention is to simplify and improve the controlling means for the power mechanism to enable said mechanism to be controlled in a simple manner and by motion of the same foot treadle which actuates the pressing members.

Further objects of the invention are in part obvious and in part will appear more in detail hereinafter.

The invention comprises the construction and arrangement of parts hereinafter described and claimed.

In the drawings, which represent one suitable embodiment of the invention, Fig. 1 is a side elevation showing the press closed; Fig. 2 is a sectional plan view on the line 22, Fig. 1; Fig. 3 is a detail sectional elevation through the pressure cylinder on the line 3-3, Fig. 2; and Fig. 4 is a detail sectional elevation through the controlling valve mechanism on the line 4-4, Fig.2.

The invention may be applied, to any form of pressing machine, but for convenience of illustration the drawings show a pressing machine of the same general form illustrated in the Patent N 0. 1,311,311, ranted July 29, 1919, to Charles L. Braley, for pressing machine. This machine comprises a suitable frame 1 having a support 2 for the stationary pressing member or garment support 3 and a pillar 4 in which is pivoted a swinging lever 5 carrying the up per pressing member or head 6 provided with an operating handle 7. Either or both of the pressing members may be provided with steam or other heating means, and with means for supplying steam for moistening Serial No. 522,954.

the garment, as is usual. 8 indicates a rearwardly extending arm of the lever 5 provided with a counterweight 9 and a depending cam arm 10 having the cam surface 11 for co operation with an antifriction member or roller 12 on one arm of an intermediate lever 13 pivoted at 14 in the stationary frame. The forward arm 15 of said intermediate lever is curved and shaped to provide a cam surface or surfaces 16 for co-operation with an antifriction member or roller 17 on the foot treadle l8 pivoted at 19 in a. support on the stationary frame. So far as described to this point the mechanism is identical with that illustrated in said prior patent to Charles L. Braley. The power operating mechanism for the press is as follows.

20 indicates a pressure cylinder, the pis ton 21 in which is normally held downward by a compression spring 22 and has a piston rod 23 extending upwardly from the cylinder. When the press is closed, as shown in Fig. 1, this piston rod lies directly beneath or registers with an abutment 24 rigidly secured, as by the bolt 25, to the lower end of the depending arm 10, said abutment having a. concave socket 26 to receive the convex upper end 27 of the iston rod. When pressure is supplied to t e chamber beneath the piston 21 the piston rod is elevated into engagement with the abutment 24 and its additional motion raises the rear end of the lever 5 and applies heavy pressure to the pressing members. The flow of pressure to and from the c linder 20 is con trolled by mechanism as fbllows:

28 indicates a valve casing in which is a supply chamber 29 supplied with fluid pressure, such as compressed air or steam, from a pipe 30 by way of an adjustable needle valve 31. The pressure supplied to said chamber flows by way of a port 32 to a chamber 33 which communicates by the pipe 34- with the piston chamber. The flow of pressure through port 32 is controlled by a valve 35 having a valve stem 36. Chamber 33 communicates by way of a port 37 with a discharge chamber 38 opening to the atmosphere through a pipe 39. The flow of pressure through said port 37 is controlled by a valve 40 having a valve stem 41. Valve stems 36 and 41 are connected to opposite arms of a lever 42 pivoted at 43 in a suitable support, one arm of said lever being pivotconnected to a swivel block 44 sliding on a rod 45 between two compression springs 46, the ressure of which may be adjusted by the 100i nuts 47. Rod 45 is pivotally connected at its forward end to an arm 48 pivotally mounted on a shaft 49 and provided with a finger 50. Said arm 48 is connected by a tension spring 51 to a second arm 52 fast upon the shaft 49 which is provided with an arm 54 a portion 55 of which lies beneath the pressure treadle l8. 56'represents a release treadle fast upon a shaft 57 provided with an arm 58 lying beneath the finger 50.

The operation is as follows:

Fig. 1 shows the press in closed position with the power pressure effective in the cylinder 20. If the release treadle 56 is depressed the arm 58 raises the finger and tilts the arm 48 backwardly. This motion, through the rod 45, compresses forward spring 46 and suddenly shifts the lever 42 so as to close the inlet valve 35 and open the outlet valve 40, thereby cutting off the flow of pressure to the cylinder and opening communication between said cylinder and the exhaust. Spring 22 thereupon moves downwardly the piston 21, and the counterweight 9 (or a suitable tension spring connected to the lever 5) depresses the rear end of said lever and raises the pressing head away from the bed. The abutment 24 therefore moves downwardly and forwardly out of range of the piston 23. The motion of lever 5 turns lever 13 and elevates the foot treadle 18, moving said treadle away from the lever 54 and allowing said lever to rise and the spring 51 to pull over the arm 52. The press is then in position for another operation. Depression of the foot treadle first moves the head down into pressing engagement with the bed and at the same time brings the abutment 24 into registering relation with and above the piston 23. The final downward motion of treadle 1S depresses the arm 54, moves the arm 52 forwardly and stretches the tension spring 51 until the tension of said spring is sufficient to pull over the arm 48 and turn lever 42 to shift the valves to the position shown in Fig. 1. In this position fluid pressure flows to the cylinder which rises and produces heavy pressure between the pressing members without further depression of the treadle 18. The same operation elevates the release treadle ready for the release operation.
