Patented Get. 28, 1930 UNITED STATES PATENT OFFICE LOREN C. TUCKER, vOF SYRACUSE, NEW YORK, ASSIGNOR TO THE PROSPERITY COM- PANY, INC., OF SYRACUSE, NEW YORK, A CORPORATION OF NEW YORK i PRESSURE MEMBER FOR PRESSING MACHINES Application led July 11, 1927, Serial No. 204,720. Renewedugust 30, 1929.

This invention relates to pressing machines as garment and laundry pressing ma.- chines and has for its object a particularly simple, etlicient and economical pressure member by which the pressure is delivered equally throughout the pressure face and by which inequalities in thicknesses of the article being pressed or inequalitiesdue to inaccuracies in the pressing machines are automatically compensated for.

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

In describing thls invention, reference 1s had to thel accompanying drawings in whichA like characters designate 'corresponding parts in all the views. l

Figure 1 1s a vertical lengthwise sectional view of this pressing member, the contiguous parts of the pressing elements as the head and buck of a pressing machine being shown.

Figure 2 is a plan View of this pressure member.

Although this vpressure member is intended primarily for garment and laundry pressing machines, it will be understood that it is applicable to other forms of pressing machines.

In the illustrated embodiment ot my invention, this pressure member is shown as applied to the lower element or buck 1 ofa. garment or `laundry pressing machine in which the head 2 moves toward and from the buck by any suitable mechanism. It will be understood however, that the head 2 does .not apply pressure'hut merely has an opening and closing movement for the purpose of permitting theoperator to arrange the garment or other article on the pressure I member and for removing the same therewhich constitute the presser face of the pressure member and means as hydraulic means for applying pressure to the inner ends of said plungers.

rlhe pressure member here illustrated comprises a hollow body 3 divided by an expansible element as a flexible or resilient diaphragm 4 into upper and lower chambers 5 and 6.

7 designates the plungers which are vmovable through guide openings 8 in the upper Wall of the body with their lower en ds engaging the diaphragm 4. These plungers are preferably spaced as close together as possible so that their end faces 9 constitute a substantially continuous presser face.

The body 3 is placed upon the buck and the chamber 6 below the diaphragm' filled with a Huid as water or oil andv connected by a pipe l() ext-ending through the buck to a suitable source of' supply of a pressure as compressed air or water pressure to apply pressure to the fluid in the chamber 6'. The application of pressure to the fluid in the chamber 6 is controlled in any suitable manner. The faces S) of the plungers are also usually covered with a suitable padding 1l.

In operation, utter the garment has been placed on the padding ll and the head 2 brought down and locked in closed position, the pressure is applied through the liquid in thevhydraulic chauiber (i expanding the diaphragm 4 causing it to push the plungers 2 upwardly and apply pressure. Those plungers underlying the Athicker portions of the garment as seams, buttons etc., will obviously not be depressed as'much as the other plungers but the pressure will be equalized through the hydraulic fluid.

Also, if the operators hand for any rcasro becomes caught between the head l and the garment, the plungers underlying thc hand Will be depressed inwardly 'farther than the other plungers without gripping or injuring the hand. -The hand may be burned as the head 2 is usually formed hollow and heated but no injury will result because of the pressure. in pressing machines now used, the hands of the operatorare not only vburned but also crushed.

This pressing machine element is particularly advantageous in that pressure can be applied to pressing machines in a simple and economical manner without more or less complicated mechanical motion transmitting means and motors etc., and in fact, Water pressure can be used to apply pressure to the fluid in the chamber 6.

' lVhat I claim is:

1. A pressing machine comprising cooperating pressing elements, one of which is movable toward and from the other, one of said elements being formed hollow and provided with a diaphragm therein dividing the saine into two compartments, one of said compartments being a pressure chamber and the other compartment being provided with a plurality of closely arranged plungers movable therethrough, the inner ends of the plungers engaging the diaphragm, the outer end surfaces of the plungers constituting the pressure face of said element.

2. A pressure member for pressing machines comprising a hollow body having a diaphragm dividing the same into two compartments,fone compartment being a pressure chamber and the other compartment having a plurality of sliding plungers guided therein and coacting at their inner ends With the diaphragm and having their outer ends located outside of the chamber for transferring the movement of the diaphragm.

3. A pressure member for pressing machines comprising a hollow body having a diaphragm dividing the same into two compartments, one compartment being a pressure chamber and the other compartment having a plurality of sliding plungers guided therein and coacting at their inner ends with the diaphragm and having their outer ends located outside of the chamber for transferring the movement of the diaphragm, said plungers being located close together and the end faces thereof forming the pressure face of said member.

4. A pressin machine member comprising a body, a plura ity of closely s aced plungers slidable through a wall of the body, the outer ends of said plungers constituting the pressure face of said member and power means within the body acting on the inner ends of the plungers and common to all of the same and servin to equalize the pressure on the plungers w en some are depressed more than others.

5. A pressing machine member comprising a body, a-plurality of closely spaced plungers extending through a wall of the body, the outer ends of said lungers constituting the pressure face of said member and hydraulic means within the body acting on the inner ends of the plungers, said pressure means being common to all the plungers whereby there is an equalizing action between the plungers.

6. A pressing machine member 'comprising `comprising an expansible element in the body foi-ming a pressure chamberv for a hydraulic fluid.

8. A pressing machine element comprising a hollow body provided with a diaphragm, the

body on one side of the diaphragm being a pressure chamber and a plurality of pressure delivering parts mounted on the other side of the diaphragm and having portions spaced apart from the diaphragm and forming a supporting surface for the article to be pressed.

9. A pressing machine comprising cooperating pressing elements, one of which is movable toward and from the other, one of said elements being formed hollow and provided with a diaphragm forming a pressure chamber on one side of the diaphragm and pressure delivering parts on the other side of the diaphragm having their inner ends pressing against the diaphragm and having outer portions spaced apart from the diaphragm, the outer portions normally forming an even supporting surface for the article to be pressed.

10. A pressing machine member comprising a plate, a plurality of closely spaced plungers slidable through said plate, theV upper ends of said plungers providing the pressing surface of the pressing machine member, pressure producing means acting on the inner ends of the plungers and a fluid pressurechamber having a flexible top in contact with the inner-ends of the plungers for, exerting pressure upon said plungers.

1l. A pressing machine member comprising a plate, a plurality of closely spaced plungers slidable throughl said plate, the upper ends of said lungers providing the pressing surface of t e pressing machine member, and a common pressure producin means acting on the inner end of each of t e lun'gers.

In testimony whereof, I have ereunto signed m name, at Syracuse, in the county of Onon aga and in the State of New York,
