Claims. 1

The invention relates to novel and improved operating means for a garment press for finishdry-cleaned garments such as suits and the Presses of this general type have heretofore been disclosed wherein a movable press head is brought into operating contact with a stationary buck either with a light pressure controlled by means of a manually manipulatable handle or lever, or with a heavy pressure by means of a foot treadle.

Anobject of the present invention-is to provide mechanism of the general character just described, but wherein the operating and control ling elements have been improved, and rendered more efiicient than those previously known in the art.

A further object of the invention is to provide mechanism of the type defined in the last preceding paragraph, and wherein the operator-operatable controlling elements are more easily manipulated and less bulky and obtrusive than those previously known.

A further object of the invention is to provide a novel and improved leverage arrangement for foot treadle operation whereby to facilitate such operation with less muscular effort than heretofore possible.

Other objects and advantages will be apparent from a study of the accompanying drawing which shows one example of a garment press embodying my invention, the drawing being a side elevational view with parts broken away or in section to show normally concealed operating parts. In the drawing certain conventional elements, such as steam supply and control parts, have not been shown, since not essential to an understanding of the invention.

The press comprises a fixed buck or bed It] carried on frame legs H, I la braced by cross members I2 and I3, the lower frame part, below the table top 9, being surrounded by a housing 14. The movable head I5 is carried on the front end of a head lever l6 which, at an intermediate point is pivoted at IT on a post l8. The head lever is operated by means of a-bellcrank havingv arms l9 and 20, the crank being freely swingable on a cross shaft 2| which extends transversely between the rear legs H of the frame. The upwardly extending arm 20 is pivotally connected at 24 to a link 25, which in turn is pivoted to head lever I6 at 26. The head lever is biased towards the head-open broken line position by a spring 21 extending between pivot points 2| and 26.

The press head 15 could be manually lowered 2 to light operating contact with the buck [0, although the usual mode of obtaining initial contact is by means of a lever or handle 28, movement of which handle, through intermediate valve devices to be later described, admits fluid pressure to a fluid motor cylinder 29. This motor is pivotally carried at 3% on a bracket 3|, which is fixed to a channel 32 extending transversely of the frame. Admission of fluid power to the upper end of motor 29 moves connecting rod 33 downwardly, and since rod 33 is pivotally attached at 34 to arm IS the said arm swings counterclockwise and applies a relatively light pressure of the head I5 against the buck.

The fluid power apparatus, and the fluid flow control system, is arranged as follows.

Handle 28 is pivotally mounted at 3? on head lever I6, and the end of the handle remote from the operator is normally biased in the direction indicated by dot-dash lines by a spring'38 so that in idle position an abutment lug 2806 on the handle is out of operating contact with the tip of a plunger 39 of a combination valve 49. This valve 40 is normally closed, but when the plunger 39 is moved upwardly it permits flow of fluid power, such as compressed air, from a pressure source (not shown) through pipes M and 42, valve 40, and pipe 13 to a diaphragm servomotor 44, which in turn acts as a relay to open master valve 45 so as to admit fluid power through pipe 4!, valve 45, and pipe 46 to the pressure head of motor 29. The tandem valve arrangement amounts to a relay system. The small valve 40 is operated by a very light touch, and its operation by handle 28 does not tire the operator. In addition, the air exhausted from cylinder 29 does not have to travel all the way back to and through valve 40, but only to valve 45 where it exhausts at 45a. The exhaust from diaphragm 44 travels rearwardly through pipe 43, and leaves valve 40 at 40c. In some. prior presses of this general type, the partcorresponding to the present lever arm l9 extended forwardly and projected out through the front of the machine. It was providedwith a foot treadle portion which the operator could operate by stepping thereon, but such construction had a number of disadvantages including the fact that it necessarily had a wide arc of swing in moving between idle and operating positions, and, being disposed in the zone of operator movement, it continually obstructed such movement.

I have devised a novel and improved structure which permits arm ill to execute its wide arc of swing within the housing, there being additional operating means outside the housing and effective upon said arm I 9, said operating means not having a wide arc of swing, and being positioned near the floor where it does not materially obstruct the operators movement. This means will now be described.

A main operating lever 49 is swingably freely mounted on shaft 2|, and is upwardly biased by a spring 50 suspended between a bracket 51 on the frame, and an eye 52 on the lever 49. An auxiliary treadle lever 53 is pivoted at 54 on main lever 49, and its end remote from the treadle part 53a has a pivoted link 55 which is operatively connected to finger member or hook 55,

the hook being pivoted at 51 on main operating lever 49.

In operation, the operator, by means of the handle 28 as heretofore described, causes the bell crank lever arm l9 to be moved downwardly from the broken line position to the full line position, which represents a relatively light pressing engagement ofthe head- IS with the buck Hi. If heavier pressure is-desired the operator now steps on treadle 53a which swings hook from the full line to the broken line position where itcomes into engagement with the operating tip end of lever arm I9 and exerts'a degree of further downward pressure on arm I9 proportionate to the force applied by the operator. By reason ofthe positioning of the treadle lever 53:, and the operating arrangement of the, linkv 55 and the hook 56, the treadle portion 53a swings through only a small arc while exerting a very heavy pressure downward" on armg'lfii. As soon as the operators footis withdrawn from? treadle portion 53a, the light spring 59 withdraws the hook 56 and releases arm l'9' of the bell crank, whereupon spring 2.1: returns the head" lever 16, the link 25, and the bell crank I9, 20 to thebroken line position. The treadle lever 53, the main lever 49, and the hook 56 are returned to the full line position by

springs

59 and 59.

Operation of the head, in the patting operation familiar to those skilled in the art, became tires'omewith prior constructions, especially since the operator had to stand clear of the protruding foot pedal. In the present construction a very light touch on handle 28 is effective to give adequate pressure for light pressing operations, without tiring the operator. The treadle in the present construction remains always at a. low point while the operator is patting the work by means of the handle 28.
