PRE'ssING-MACHINE.

To all whom it may concern:

Be it known that I, SHAIN E. BAITARY, a citizen of the United States, residing at Baltimore, State of Maryland, have invented certain new and useful Improvements in Pressing-Machines, of which the following is a description, reference being had to the accompanying drawings, forming a part hereof.

Myy invention relates to pressing machines such as are used for pressing garments and in whichthe garment is subjected to action of steam and pressure, the steam acting to slightly moisten the material of the garment as well as to heat the pressing means. Machines of this class generally comprise an upper and a lower pressing head or buck the two being arranged to be brought together to press the garment between them, the lower buck being usually stationary and the uppier buck being movable. The upper buck is made hollow to form a chamber to receive steam under pressure and its pressing face is formed with numerous perforations to permit the Asteam to pass through into the material of the garment and the lowerbuck usually has its pressing face also formed with numerous perforations leading to a chamber beneath the face connected with exhausting means by which steam discharged from the upper buck is drawn through the material of the garment. In the use of such pressing machines there is a great waste of steam and the escaping steam loads the atmosphere of the room in ywhich the pressing machine is located with moisture to the discomfort of the operator and to the detriment of his health as well as to the detriment of everything in the room which is capable of being injured by excess of moisture. This escape of steam is in large measure due, if there is strong exhaust from the lower buck, to the fact that usually the garment or the portion of it to be pressed does not cover the entire area of the pressing faces of the bucks and leaves,l usually, a considerable portion of the face of the upper buck with nothing but space between it and the face of the lower buck into which the.

steam has practically freek escape, the suction from the lower buck having little effect to dispose of the steaml so escaping through lthe perforations of the face of the upper buck which are notin contact with the material of the garment being pressed. In order to dispose of even a portion of the steam so Specification of Letters Patent.

Application led January 6, 1920. Serial No. 349,769.

escaping the exhaust must be very strongV if it is to draw steam throughthe material of the garment.

It is the object of my invention to provide a construction of the upper presser head or buck which will prevent the escape of steam not needed' for the pressingoperation and will permit steam to be discharged only through such portions of the pressing face as are in direct contact with the material of the garment or portion of the garment to be pressed.

A further object of my invention is to provide a' construction by which, if desired, a constant pressure of steam may be mainaiipd in the steam chamber of'tlie upper With the -objects above explained and land combination of elements hereinafter described and claimed.

Referring tothe drawings;

Figure l is an end view partly in setion of a pressing machine having' an upper buck embodying my invention,

Fig. 2 is a detail cross sectional view of a portion of the upper buck, y

Fig. 3 is a plan view, partly broken away, of the underside or pressing face of the upper buck,

Fig. 4 is a top plan View of one of the lower valves,

Fig. 5 is a bottom plan View of the valve shown in Fig. 4 and Fig. 6 is a detail cross sectional view on an enlarged scale showing the construction of the valves.

In the drawings 1 indicates the upper pressing head or buck and 2 indicates the lower pressing head or buck here shown as stationary though it may be arranged yto be movable if desired. This lower or stationary buck may be of any usual or desired c0nstruction as it forms no part of'my invention. As shown it comprises a suitable cast iron'frame hollowed out onits upper face as shown at 4 with the usual perforated plate so as to be brought down onto the garment to be pressed which is laid in the usual way on the pressing face of the lower buck. The upper buck comprises an upper plate 11 and a lower plate 12 spaced apart a suflicient distance to form between them a steam chamber 13 to which steam is supplied by a steam pipe 14. The lower plate 12'is relatively thick and is provided with a series of openings 15 through it having valve seats 16 at their upper ends and valve seats 17 at their lower ends. In each opening 15 is arranged a valve rod 18 having at its upper end a valve -19 fitting the valve seat 16 and at its lower end a valve 20 fitting the valve seat 17. The valve rod 18 is of such length that the valves 19 and 20 are a distance apart greater than the thickness of the plate 12. Springs 22 carried on the valve rods serve to press the valves 20 downward away from their seats and to hold the valves 19 against their seats so as to prevent steam from passing through the openings 15. The valves 20 are provided with perforations 23 and preferably also with edge grooves 24. The valves 20 are not strictly valves in the sense of serving to close the openings when they are seated as the perforations through them permit free passage of steam but when seated they serve to fill the lower ends of ,the openings 15 so as to present a. substantially smooth surface for the pressing face. Over the lower faces of these valves 20 'a cloth 25 is preferably stretched.

When the upper buck is in raised position the valves19 are all held against their seats 16 by the springs 22 as well as by the pressure of the steam in the steam chamber 13, if steam has been turned on, the valves 20 being extended below the lower face of the plate 12 as shown in Fig. 1. After the garment to be pressed has been placed onthe I upper face of the lower buck 2 in the usual way the upper buck is brought down swings. mg on the center 10, the steam being, of

course, turned on, if there is not already steam pressure in the steam chamber .13. If the garment to be pressed covers the whole upper surface of the lower buck the contact of the valves 20 throughout the entire surface of the upper buck with the material of the garment through the cloth 25 will cause all of the valves 19 to be lifted from their seats permitting the steam to pass into the openings 15 and escape through the perforations 23 and grooves 24 to permeate the material of the garment and pass through the cloth 6 and perforated plate 5 and be carried away by the exhaust without any of the steam escaping. This action would be the same with the ordinary construction of upper buck when the garment to be pressed covers the entire surface of the throughout an area corresponding to the area of the garment or portion of garment will there be any escape of steam and the steam so permitted to escape will be to a great extent taken up by its action on the material of the garment and the excess will be carried off by the exhaust. Loss of steam is thus avoided lessening the expense of maintaining the steam pressure necessary for operation and the damage due to the moisture from escaping steam will be prevented.

The upper buck constructed as described may be made of any size or shape desired and may be readily adapted to be substituted in pressing machines now in use for their upper bucks.

I do not desire to be limited to the particular construction of valves or means for closing them shown as various changes in details of construction may be made without departing from the spirit of the invention.

. Having thus described my invention what I claim is: v

1. An upper buck for a pressing machine having a steam chamber formed therein and comprising a plate having openings therein communicating with the steam chamber, valves normally closing thel openings and means adapted to be operated by the garment to be pressed for opening the valves.

2. An upper buck for a pressing machine having a steam chamber formed therein and pressing surface of the buck in position to`v be operated by the garment to be pressed and springs acting to close the valves.

In testimony whereof I ali-ix my signature this 5th day of January, 1920.
