sucx STEAM VALVE OPERATING ATTACHMENT FOR GARMENT PRESSING MACHINES Filed May 29, 1950 INVENTOR. HARRY KOLKER BY Li/Mau Patented Mar. 3, 1953 UNITED STATES PATENT OFFICE BUCK STEAM VALVE OPERATING AT- TACH1VIENT FOR GARMENT PRESS- ING MACHINES 9 Claims.

This invention relates in general to garment pressing machines and, more particularly, to certain new and useful improvements in a buck steam valve operating attachment therefor.

Garment pressing machines now generally in use are operated with steam fed to the head which is accomplished by manipulating a hand lever for opening the head steam valve after the head has been lowered into pressing position by means of a main foot lever. These machines are ordinarily equipped with a separate pedal or foot lever for actuating the buck steam valve should the user desire to present steam to the buck. However, since this operation would require the simultaneous utilization of both of the operators feet, it is readily seen that such is highly awkward and, hence, most seldom performed. Furthermore, since bucks are relatively heavily padded, having numerous thicknesses of felt and similar material, a substantially large amount of steam is required for penetration thereof which is relatively uneconomical. For these reasons, steam feeding the buck has not been generally practiced heretofore.

Therefore, it is the primary object of the present invention to provide an attachment for garment pressing machines whereby steam will be fed to the buck upon operation of the main foot lever, obviating the contemporaneous actuation of a second foot lever.

It is a further object of the present invention to provide an attachment for garment pressing machines of the character stated which is readily adjustable for controlling the amount of steam fed to the buck.

It is an additional object of the present invention to provide an attachment for garment pressing machines of the character stated which may be readily mounted upon currently used pressing machines.

It is a still further object of the present invention to provide an attachment for garment pressing machines of the character stated which, having a simplicity of parts, is economical to manufacture and durable and reliable in usage.

With the above and other objects in view, my invention resides in the novel features of form, construction, arrangement, and combination of parts presently described and pointed out in the claims.

In the accompanying drawing,

3 Figure 1 is an elevational view of a conventional type garment pressing machine incorporating a buck steam valve operating attachment constructed in accordance with and embodying the present invention;

Figure 2 is a front view of the frame and buck of the pressing machine;

Figure 3 is an enlarged side view of the attachment taken substantially along line 33 of Figure 2;

Figure 4 is a transverse sectional view taken along line 4-4 of Figure 3; and

Figure 5 is a fragmentary transverse sectional View taken along line 55 of Figure 1.

Referring now by reference characters to the drawing which illustrates a preferred embodiment of the present invention, A designates a conventional type garment pressing machine having a frame I, a table 2 mounted thereon, and a pedestal 3 upon which is mounted a buck or stationary pressing form 4. The rear portion of the frame I extends upwardly and pivotally supports a pressing lever 5 having disposed on its forward end a head or movable pressing form 6 for co-operation with the buck 4, and on its opposite end a counterweight l. Operatively connected to the pressing lever 5 by conventional toggle mechanisms generally designated B is a main lever 8 having an integrally formed pedal portion 9 on its outer end which projects forwardly through a central opening H3 in the frame I. Depression of the lever 8, which is normally biased upwardly, will cause the head 6 to be rocked downwardly into pressing position upon the buck 4. Said buck 4 is adapted for receiving steam having a steam inlet pipe ll connected to a source of steam (not shown) and a steam return line I2.

Mounted by bolts [3 upon one side of the main lever 8, adjacent its inner end, which is just inwardly of the forward face of the frame I, is

an angle bracket 14 having an aperture l5 drilled in its horizontally extending section It for receiving the depending threaded stem ll of an upwardly opening socket-forming member 13, said stem ll having a nut l9 secured thereon. Fitted within the socket-forming member l8 for rocking movement therein is a ball 28 rigidly fixed, as by welding, upon the lower end of an upwardly extending rod 2|, the upper portion of which projects into a tube 22. Said tube 22 is provided substantially throughout its length with a relatively narrow elongated aperture 23 for exposing the aligned portion of the rod 2| in which is tapped a plurality of vertically spaced, relatively shallow bores 24 for selectedly receiving a stop screw 25. It will thus be seen that the extent of downward sliding movement of the rod 2| within the tube 22 will be determined by the selected position of the stop screw 25 within the bores 24, as such movement will be terminated by detaining abutment of the screw against the lower margin of the aperture 23.

Fixed to the upper end of the tube 22, as by welding, is a ball 26 which is fitted into a downwardly opening socket-forming member 2'! integrally having an upwardly presented stem 28 projecting through an aperture 29 in the inner end of a rocker arm 30, said stem 28 being secured by a nut 3|. The rocker arm 30 extends forwardly through an opening 32 in the outwardly presented face of the frame I, the outer end of the rocker arm 30 being enlarged and drilled for rigidly securing same, as by keying, upon a transverse cross shaft 33 disposed spacedly beneath the forward portion of the table 2. Said cross shaft 33 is journaled at its ends in bearing members 34, 35, mounted upon the under face of the table 2. The ends of the cross shaft 33 extend beyond the planes of the side faces of the frame I. Inwardly of one end of the shaft 33, in outwardly spaced relation to the adjacent side face of the frame I, there is fixed upon the shaft 33, for rocking movement therewith, the base of an inwardly opening clevis 36 through the mouth of which freely projects a vertically disposed valve rod 31, said clevis 36 being perforated at its ends to receive a pin 38 extending therebetween to prevent inexpedient displacement of the clevis 36 with relation to the valve rod 31. under face, the clevis 36 abuts against the upper surface of a collar 39 fixed upon the valve rod 31. At its lower end, said valve rod 31 projects loosely through a suitable aperture in the horizontal section 40 of an angle bracket 4| secured to the adjacent side wall of the frame Encirclingly disposed about the valve rod 31 is a spiral spring 42 which bears at its lower end against the upper face of the horizontal section 40 of the bracket 4| and at its upper end against the under face of a collar 43 rigidly secured upon the valve rod 31 in downwardly spaced relation to the collar 39. Coupled to the valve rod 31 at its upper end is a buck steam valve 44 which is disposed within the base portion of the buck 4 for controlling the admission of steam therethrough from the steam inlet pipe I I.

It is apparent that the machine A may be provided with a system for feeding steam to the head 6, the valve for which may be either operated manually or by actuation of a foot pedal such as 45. Said machine A may also be provided with a customary vent valve and vacuum valve actuated by foot levers 46, 41, respectively.

In usage, upon depression of the main lever 8, in order to lower the head 6 into pressing position, the rod 2| will be carried downwardly with its upper portion sliding freely in the tube 22, said tube 22 being normally stationary since the cross shaft 33 is prevented from unauthorized rocking movement by the upward pressure of the collar 39 upon the clevis 36 through bias of the spring 42. When the stop screw 25 comes into detaining abutment against the lower margin of the aperture 23, the tube 22 will be carried downwardly by continued downward movement of the rod 2| through further depression of the main lever 8 whereupon the rocker arm 30 will be rocked downwardly causing the cross shaft 33 to be rocked commensurately. A corresponding rocking movement will be imparted to the clevis 36 causing same to drivingly engage the collar 39 to move the valve rod 31 downwardly against the tension of the spring 42. The downward travel of the valve rod 31 will cause the valve 44 to be Upon its lowered into open position, permitting the entry of steam into the buck 4 for pressing purposes. Release of the main lever 8 by the operator's foot will move the valve 44 to closed position with the simultaneous upward swinging of the head 6.

It will thus be seen that the amount of steam admitted to the buck 4 can be regulated by the positionment of the stop screw 25 within the bores 24 of the rod 2|. For example, if a maximum amount of steam is desired, the stop screw 25 will be inserted in the lowest bore 24 whereupon the sliding movement of the rod 2| will be minimal prior to abutment of the stop screw 25 against the lower margin of the aperture 23 so that the tube 22 will be moved downwardly during substantially the entire course of the act of depressing the main lever 8. Hence, a maximum rocking effect will cause the shaft 33 with a corresponding downward thrust upon the collar 39 by the clevis 36 to cause the valve rod 31 to be lowered for disposing the valve 44 in maximum open position. Conversely, if a minimal amount of steam is desired to be fed to the buck 4 the stop screw 25 will be positioned in the uppermost of the threaded bores 24 so that downward movement of the tube 22 will not be effected until approximately immediately before the completion of the depression of the main lever B. This will cause a minimum rocking of the shaft 33 so that the valve 44 will be moved into minimum open position. Clearly, any desired gradations in amount of steam between maximum and minimum may be effected by positioning the stop screw in the other threaded bores 24.

It is to be noted that the rod 2| and tube 22 will be maintained along an axis substantially perpendicular to the floor by free rocking of the

balls

20, 26, within their respective sockets |8, 21. Furthermore, the spring 42 will remain serviceable throughout extensive periods of operation since it is not subjected to any torque but solely to an axially directed force.

By the practice of the above described invention, it has been discovered that the buck 4 may be substantially stripped of padding and be supplied with but a single surface layer. This feature assures maximum economic utilization of the steam fed to the buck 4 and, additionally it has been found that such will cause a most attractive finish to be imparted to the garments, a finish which has not heretofore been accomplished by feeding steam to'the head.

It is apparent that the invention herein described could be readily mounted upon the various types of garment pressing machines in current use without requiring other than relatively simple mechanical adjustments.

It should be understood that changes and modifications in the form, construction, arrangement, and combination of the several parts of the buck steam valve operating attachment may be made and substituted for those herein shown and described without departing from the nature and principle of the present invention.
