DALY, OF SYRACUSE, NEW YORK, ASSIGNOR TO THE PROSPERITY COMPANY INC., OF SYRACUSE, NEW YORK, A CORPORATION OF NEW YORK GARMENT OR IRONIN G PRESS Application filed July 9, 1926, Serial No. 121,366. Renewed May 6, 1931.

This invention relates to pressing machines, such as garment and laundrypresslng or ironing'machines and has for its object a particularly simple and efficient power actuating mechanism to actuate one of the press jaws, and more particularly a power mechanism embodying a reciprocating actuator, as the piston rod of a piston movable in'a cylinder: it further has for its object a particularly simple and efficient means for controlling the flow of motive fluid to the cylinder in such a way that the movable pressing element or head must be preliminarily closed by hand before the motive fluid can be admitted to the cylinder, and the preliminary closing movement of the head is independent of the actuator, and does not move the actuator so that the full power stroke of the piston is utilized in applying pressure. 1

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

In describing this invention reference is had to the accompanying drawings in which 1 like characters represent corresponding parts in all the views.

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

Figure 2 is a detail sectional view of the manual control valve shown in open-press position.

Figure 3 is a detail sectional view of the cut off valve automatically operated by a movable part of the machine.

Figure 4 is a detail fragmentary view of the cylinder'and piston movable therein.

Figure 5 is a sectional view of the press frame on line 55, Figure 1, parts being omitted.

I have here illustrated my invention as embodied in a conventional type of garment and laundry pressing machine comprising press jaws such as a buck 1 and a head 2 movable toward and from the buck, the buck being carried by a goose neck 3, which in turn is mounted on a frame 4. The head 2 is carried by a yoke or lever 5 pivoted at 6 be tween its ends to a standard 7 rising from the frame, and said lever carries the head 2 at itsfront end, and is connected at its rear to open-the crating movement.

end to the actuatin mechanism. A suitable handle 8 is mounte on'the front of the yoke by means of which the head 2 is preliminarily closed by hand, a counter weight 9 tending press being mounted on the rear end thereof.

10 is the cylinder and 11 the piston movable in the cylinder and having a rod 12, the piston and its rod constituting a reciprocating actuator. The cylinder is mounted in the rear leg 13 of the machine of which the standard 7 is an upward extension and is pivoted at 12a therein so as to have an op- The rear leg is in the form of a channel. It' will be understood that the frame has but a single rear leg centrally located.

The motion transmitting mechanism. be-

. tween the actuator 12 and the yoke lever 5,

as here shown, includes a part with which the actuator or rollers 14 at its ends has sliding connection, this part being a lever 15 pivoted between its ends at 16 to the frame, and having one arm pivoted at 17 to the lower end of a link 18, the upper end of which is pivoted at 19 to the yoke lever, the other arm of the lever 15 coacting with the rollers 14 which rollers slide or move lengthwise of the lever from its axis toward the outer end of the lever during the power stroke.

Each of the rollers 14 is guided in its movement by a cam slot 20 formed in the tively to the slot, so that a long movement of the piston is transferred'into a short movement of the lever 15, and finally as the roller approaches the end of the arm 15, it takes an abrupt rearward movement to apply the final pressure due to a rearward deflection 22 at the lower end of the slot 20. Owing to the sliding connection between the reciprocating actuator or piston rod 12 and the part or lever 15, the head can be preliminarily closed without requiring any movement of the actuator 12 so that the full throw of the actuator 12 is utilized in applying the final heavy pressure, and the long throw of the actuator is converted into power or a short movement of the lever 15 due to the movement of the actuator 12 or its follower l4 lengthwise of the lever.

Motive fluid as steam or air is supplied to the cylinder from a suitable source of supply through a ipe 23 and is controlled in its flow to and rom the cylinder 10 by a valve 24 having a. manually operated handle 25. The piston here shown is double acting and in operation the motive fluid enters the pipe 23 and past an automatic safety means comprising a cut out valve 26 to be presently described, then through a pipe 27 to'the intake port 28 in the valve casing of a valve 24:, thence through the passage 29 of the core or movable member 30 of said .valve, through port 31 and a pipe 32 to the upper end of the cylinder so that the piston is depressed to the full end of its throw. During such movement of the piston the fluid exhausts from the lower end of the cylinder through pipe 33, port 34 of the exhaust valve 21, valve passage 35 of the valve 30 and out through the exhaust port 36. To open the press, the

valve member 30 is moved by the handle 25 into the position shown in Figure 2 so that the air enters the bottom of the cylinder through pipe 37 port 38, passage 35, out through port 34, and at the same time the air exhausts from the top of the cylinder through the pipe 32, port 31, valve passage 29 and exhaust passage 38.

The safety valve means 26 shown in Figure 3 is a one way valve normally in closed position when the press is open, and arranged so that its passage is brought into alignment with the pipes 23 and 27 only after the head 2 has been preliminarily closed so that ordinarily the motive fluid from feed pipe 23 cannot be led into the cylinder unless the head has been preliminarily closed. The valve 26 is a rotary valve, the rotatable part of which has a rock arm 40 thereon which is connected by a link 41 to the rear arm of yoke lever 5; thus power can be ,applied to the head only after it has been brought down to preliminary closed position by hand. The head can be opened at any time by operating the control valve handle 25 so as to permit the air to exhaust from the upper end of the cylinder, and enter the lower end through the pipe 37. The press head is opened as the piston moves upwardly in the cylinder by the counterweight 9 and countersprings.

This machine is particularly advantageous in that it provides a way by which in a machine operated by a cylinder the head must be preliminarily closed by hand, and another Also the full stroke of the piston is utilized to apply pressure and no part of the stroke utilized to preliminarily close the ,press.

It is therefore seen that an ironing press is produced which is safe in operation in that a safety valve means 26 functions to render the control handle 25 ineffective until after the press head has reached safe position on the buck. The valve 26 may be a one-way valve means, as shown in the illustrated example of the invention, and thru which a flow of air takes place toward the frontof the press to the valve and handle means 24-25. to render the latter effective to produce heavy pressure between the jaws 1 and 2 only. after the press has closed. The one-way safetyvalve means 26 may be operatively connected with the press lever 5 and automatically opened thereby after the head reaches the buck.

Thus the press head 2 is capable of being closed or moved toward the buck without in any way being under the driving force of the heavy pressure cylinder 10. The one-way safety'valve means 26 cuts out the power cylinder 10 until it is safe to admit air pressure to the motor means 10. What I claim is .1.
