end of the press lever 11 and isA adapted to be y. l closed on the work after it is spread upon k This invention relates to pressing machines.

and more particularly to steam power presses operated by Huid pressure and which is adapted for use in garment pressing and laundry ironing work and for other purposes.

Anobject of the invention to produce a. i'

` `The preing head 13 as well as the buck power.]aw'for presses, `a jaw simple indesign and construction and embodying a diaphragm-type power producing motor meansV 10 operated by steam or otherluid pressure.

A further object is to produce a novel power jaw ywith fluid-pressure motor -means placed within the jaw together with an autov matic throttle valve which is actuated by the operating means used to open and close the press, the result being to automatlcally start the-operation of the motor means after the jaws f a press. j l g Other objects of the invention will be understood from af consideration of the accompanying drawings and following description.

Changes may be made without departing from the principle of the invention.

Figure 4 illustrates a longitudinal section-v al view of the pressing member or power jaw in which is incorporated the improved power and the pressure producing motor means.

' Referring now tothe drawings fora furl ther description of the invent-ion,v there is shown la press frame 10 on which is mounted press lever 11 pivoted at 12 on the frame and a press head jaw 13 is carried on the forward 14-15 'are usually steam heated and when this type of press is used, the steam isV conveyed to the press through a'steam feed ipe 15 `and the same steam which is availab e to heat the press is also usedfor operating the compression motor meanswhich'makes for economy in heating andpower operating the pres because one and` the same medium is A Referring further to thel improved construction of one of the jaws, as for example the buck or lower jaw,l there is shown a stationary aw plate, support or mounting plate 14 anchored to the framell'f) and thereupon. is mounted a rigid and relatively movable compression plate 17. The two members 14 and 17 together constitute the lower press jawl and one part thereof is movably relatively to and on the other to producey jaw compression for high pressure laundry ironing work or for pressing seams and the like in the manufacture of garments. Within the composite jaw structure there is mounted a simple disk diaphragm expansion motor to perform all the work incident to producing high jaw compression. The com ression plate 17 may be made hollowif desired for the purpose'of receiving the steam intoa steamheating chamber 16 to heat the compression plate and for other use if desired.

The compression plate-may be made with aI depending marginal flange 18 having clearance from and between a corresponding upturned flange 419 made integral on the stationary jaw plate 14. The anges 18 and 19 or other means guide the compression plate 17` up and down in relationto the stationary jaw plate 14 and clearance is leftbetween the guide yflanges 18 and 19 to permit the compression plate 17 to undergo a slight oscillating or wobbling motion on, about, or in relation/to the .other plate 14 in order that its front or rear edge may travel'more i 2o f and a small amount of steam 1s therefore or less, than its other. edge thereby accom# modating itself to unevenness and irregularity of seams or other work to be pressed beconstruction.

One or more upstanding ribs -or flanges 21 are made in one of the jaw members, in this instance inthe stationary -aw late'14, and a fiat type corrugated exib e disk. dlaphragm 22 has its outer edge mounted on the rib 21 and sealed in.` by a ring 23 or other `suitable means. In this way a diaphragm steam receiving expansion chamber 24 is formed ressure tight between the 'corruf 'gated disli diaphragm 22 and the-wall of the stationary jawv late 14. f i

Itis noted t t the diaphragm 22 forms one-head of the steam expansion vchamber 24- and the solid wall of the plate 14 forms the other head of the steam expansion chamber and that the circular rib defines the wall of the steam expansion chamber. This chamber 24 possesses a small volumetric capacity uired to fill it. l

n the drawings there is shown a pressing jaw or buck provided with several, in this instance two, spaced corrugated disk diaphragmS, one being mounted in the jaw toward each end thereof, or lany suitable numi fber of ll'uid diaphragms areused for ordinary ironingand pressing operations. Tlre size or area of the press jaws and the compression required 'determines the number of and thel diameter of the disks incorporated into the press jaw. 'v

The outer edge of the corrugated disk diaphragm is hermetically sealed on one ofthe jaw members, in this instance on the stationary jaw'pl'ate 14, and the center of the disk diaphragm normally rests in contact with the compression plate 17. The expansion of the disk therefore lifts upwardly on the compression plate with great force to press it against the head and thus produce jaw compression.

A feature of "this power ress is that the motor means operates off o the same fluid pressure. steam, as used to heat the press jaws, The center of the diaphragm disk may if desired be sealed onto the inside wall of the compression plate 17 by any suitable means as for example, by a-nut 26. In the present instance, the nut 26 may to advantage be made hollow and is screwed into a steam passage leading to the heating cham ber 16 to permit steam to circulate through the heating chamber. The nut 26secures the center of the disk diaphragm 22 to one` jaw member and the perimeter thereof being secured to the other 'aw forms the steam ti ht expansion cham er 24 aforesaid into w 'ch steam is received to force upwardly on the flexible diaphragm during the press-I ing operation thereby moving the pressing plate 14 upwardly with great force. f

The flexible plate or disk type diaphragms 22, one or more thereof being used, in one or both jaws, possesses sullicient flexibility inherent therein as to rmit considerable ilexure or distortion in ltsnwall. The lexure `in the diaphragm is increased somewhat by the circular concentric corrugations spun 'into the disk 22 and when steam is turned into the compression chamber 24, a substantial pressure is exerted upwardly on the diaphragm 22 and steam at the same time flows through the `passage 28 to heat the pressing plate 17 heretofore mentioned. l

It is significant that this power press' jaw is compact, that the motor means 22 is placed adjacent and directly in contact with the rigid compression plate 17, and there are no intervening parts between the rigid press plate and steam motor means.

Steam pipes 30 transmit steam to one or more compression chambers 24 anda feed pipe 31 connects the pipes `30 with the steam supply pipe 15 heretofore mentioned. Automatic valve control means Vmay be used to open the steam into the diaphragm chambers 24v ifl desired so that when the press head1?) is closed,the diaphragms 22 automatically expand to produce jaw compression.

.A steam valve 33 is mounted in the pipe 31 and is preferably spring closed and embodies a valve stem 34 which closes upwardly7 against or in line with a valve push rod plunger 35, the upper end of which is pivotally connected' at 36 to the press lever 11.

As the press lever 11 moves downwardly, the,

valve plunger 35, held vertically by a parallel motion arm 37, impinges the valve stem 34 and opens the valve 33 thereby permitting steam to flow into the pipe 31 and hence to the one or more steam expansion chambers.

A steamexhaust valve 39 is mounted in v pipe line 31 and a control handle 40 is connected to the exhaust valve 39 which is normally held open as by a spring 41 ory other suitable means so that said valve is always open as shown in Figure 2 -in order that steam may ilowpast the valve 33 through the ex haust valve 39 and directly to the one or p more lcompression chambers 24 immediately the head13 has reached lowermost' position in contact with the workon the compression plate 17. The spring 41 therefore holds the valve 39 open as shown, with the waste or exhaust pipe 50 closed, the result of which is to leave free both hands of the operator so that he may quickly adjustthe work and draw the head 13 down thereuponl and instantly the throttle valve automatically opens to permit a flow of steam t9 the diaphragm expansion chamber which produces' instant jaw compression which continues c until the operator turns the exhaust valve 39 to permit discharge of steam from one or .more expansion chambers through exhaust pipe to atmosphere. whereupon the expansive force of the disk diaphragm subsides 10 and jaw pressure is released.v

The fact that a fiat type corrugated tiexible disk diaphragm is used makes for economy in structure and economy in steam. The steam expansion chamber 2l is relatively small.

Furthermore, the movement of the compression plate 17 is very little, just sufficient to compress the work. This is dueto the fact that the operator physically brings the'head 13 down in close engagement with the com- 20 pression plate 17 and'thework thereon before they diaphragm is acted on by steam. The

` compression plate 17 therefore moves upwardly a dista-nce substantiallv'equal to the compressional and contractional ability of the work which is verv little in actual niovement or travel of the plate 17 on the other plate 14. Therefore the movement ofthe diaphragm,

i. e., its flexure is exceedingly limited which isfan ideal working condition conducive tol long life ofthis improved motor means.

i It is`to be noted that the diaphragm 22 per-A forms a triple function in that it atfordsa compensated wobbling motion of the compres-'- sion plate 17 in relation to the, stationary buck plate 14 and hence the'compression plate 17 is mobile and adjusts itself in function when under pressure to unevenness in the work as to seams and other irregularities in the work to be pressed;` likewise the diaphragm with 40 its passage 28 aiords a flexible connection of a new kind between the two fluid chambers 16 and 24 and 'it is. evident that there are no moving parts other than the lexure of the diaphragm itself; and finally there is the .mo-

4,51 `tor-means function of the diaphragm in that it produces the necessary power to press the work under high jaw compression between the head 13 and press-buck plate 17. Hence is explainedgthe triple functions of the dia- 56 phragm. e,

is eliminated movable parts suchas stuling.

boxes and the like usually employed to con-l 'Vey fluid presure from a stationary part to a movable part. At'f; the same time the dia- 60 phragmadmits of inobility and' adjustment l of the compressionplate to accommodate unevenness met with in the work as already eX- plained. The simple motor means shown performs all three functions separately or together and the construction is of the simplest secured in service position on a frame, means y for loosely maintaining the rigid compression plate on the mounting plate during the relative motion, and motor means within the jaw to execute with great force the relative motion aforesaid.
