(0.384 -17) the head and fabric during pressing engagement, which causes the fabric to be lifted away from the buck upon elevation of the head. -In additionfcertain' prior art pressing-machine devices permitted condensation of steam to cause water spots and stains on=the fabric being pressed. i a

Accordingly, ity is an object ofthe present invention to provide a highly advantageous improvement, for use 2,973,594 Patented Mar. 7, 196! Fig. 4 is a sectional elevational view similar to Figs. 2 and 3, showing the head of the pressing machine completely removed from its pressing relation with the buck.

Referring now more particularly to the drawings, and specifically toFig. '4 thereof, a pressing-machine frame is there designated 10, and includes a conventional upwardly facing, fixed buck 11. Rearward of, the buck 11, the frame 10 is provided with an upstanding journal support 12. An arm 13 is pivotally connected to the upstanding journal support 12 by a journal pin or shaft 14;;and-the arm 13 extends generally forward and upward from its journal 14 as seen in Fig. 4. However, the arm 13 is swingable relative to the frame 10 about the axis of the journal pin 14.

In Fig. 1 it may be observed that the arm 13 includes a pair of forward-end extensions or furcations 15, to the underside of Whichis'fixedly secured an elongate head 16,

as by fasteners 17. As seen in Fig. 1, the head 16 is of laterally elongate configuration, in the conventional manner; and thebuck 11 is also laterally elongate in' the -conventional manner. Suitable manually actuable operating controls 18 may be-provided on the upper side in pressing machines, which overcomes the above-mentioned difliculties, eliminating scraping and lifting of. the fabric being pressed by the head, and consequent wrinkles and distortion of the fabric, and which effectively prevents condensation of steam likely to cause water spots and stains. f e 7 It is-a further object of the present invention to providea devicehaving the advantageous characteristics cally manufactured and installed for sale at a reasonable I i mentioned in the preceding paragraphs, which is adapted ing relation of the head 16.

As thus far described, the structure is that of a conventional pressing machine, wherein the head -16-is mounted for swinging movement with the arm downward toward the buck 11 into pressing relation therewith, and upward movement away from the buck and out of pressing relation.

The improvement of the present invention is generally designated 20 and includes a plate 21 of heat-conductive material, such as aluminum, interposed between the buck 11 and head 16 for conforming sandwiched engagement therebetween upon movement of the head into pressing relation with the buck, as seen in Fig. 2. The plate 21 is preferably perforated or formed with apertures 22 for the passage therethrough of steam. An upstanding peripheral wall or flange .23 is preferably provided extending completely about the plate 21 conformable to and receiving the head 16 when the latter is in its press The flange 23 may advantageously .be formed integrally with the plate 21 of aluminum or other suitable'heat-conductive material.

. On the rearward: side of the head 16, at spaced locations therealong, are provided a pair of hinges 25, each having one hinge plate fixed to the adjacent region of i the plate flange 23, and having its other hinge plate Other objects of the present invention will become material part' of this disclosure. a

apparent 'upon reading the following specification and referring to the accompanying drawings, which form a construction, combinations of elements, and arrangements of parts, whichwill be exemplified in the'construction hereinafter described, and of which the sco pe will be indicated by the appended claim. 1

In the drawings:

Fig. 1 is a partial top plan view showing a pressing machine employing a device constructed. in accordance fixed to the rearward side of the head 16 by an extension or. bracket 26. The hinges 25, and their brackets 26, are advantageously fabricated of heat-conductive material for transmitting heat from the heated head 16 to the plate 21. The pivotal axes of the hinges 25 are in substantial alignment with each other so as to mount the plate 21 for swinging movement relative to the head.

Specifically, the plate 21- is swingable about the aligned position of Fig. 4 spaced below and away from the underside of'the head.

On the forward side of the head 16, at laterally-spaced locations. therealong, are means designated 28 connecting the forward side of the head to the forward region of the plate and limiting swinging movement of the latter away from the head about the axes of hinges 25. In particular, each of the connecting means 28 may include an angle bracket 29 fixed to the forward portion of plate flange 23 and extending upward therefrom; Carried by the upper end of each bracket 29 and projecting upward therefrom is a headed bolt or pin 30,- which may be fixed relative to the bracket 29. An additional angle bracket 31 may be fixed to the forward side of the head 16 adjacent to each bracket 29 and provided with a forwardly extending portion loosely receiving the pin 39 for sliding movement of the latter through the bracket 31. Resilient means, in the form of a coil compression spring 32, is circumposed about each pin 30 and has its opposite ends in bearing engagement with thebrackets 29 and 31, respectively, and compressed therebetween to resiliently urge the pin 30 downward to the position limited by engagement of the head of the pin 30 with the bracket 31. This condition is illustrated in Fig. 4. The plate 21 is swingable toward the head 16 to the position of Fig. 2 by compression of the spring 32.

From the condition of Fig. 2, wherein is seen a fabric or piece 34 being pressed, it will be noted that the plate 21 is sandwiched between the head 16 and buck 11, in pressing engagement with the fabric 34. Upon cessation of the pressing operation of Fig. 2, the head 16 is elevated, in the direction of the arrow 35 of Fig. 3, which simultaneously elevates the rearward side of the plate 21, the latter being directly hinged to the head. Thus, the plate 21 is raised from pressing engagement with the fabric 34 initially at its rearward side and progressively forward, the forward side of the plate 21 remaining in pressing relation with the piece 34 appreciably after upward movement of the head 16 has been initiated. Of course, continued upward movement of the head 16 raises the entire plate 21, including the forward region thereof from the buck 11 and fabric 34, the condition illustrated in Fig. 4.

During this above-described upwardly movement of the head 16 and removal of the plate 21 from its pressing engagement with the fabric 34, air is gradually permitted to enter between the plate 21 and fabric 34 from the rearward side to prevent or destroy any vacuum or suction therebetween. However, the plate 21 remains quite hot, although being spaced from the heated head 16, by means of heat conduction from the head to the rearward region of the plate, as through the hinges 25 and brackets 26, so that steam will not be condensed and water spots and stains will be eliminated.

Relative movement of the forward region of the plate 21 with respect to the buck 11 during the initial upward movement of the head 16 is negligible, so that no scraping or creasing of the fabric occurs. If desired, the aligned axes of hinges 25 may be located relative to the axis of journal pin 14 to obtain a substantially stationary position of the forward plate edge relative to the buck 11 during the initial upward movement of the buck, as by locating the journal pin 14 such that the head 16 and hinges 25 swing upward and-slightly forward at the inception of upward head movement.

From the foregoing, it is seen that a pressing-machine apparatus is provided which fully accomplishes its intended objects and is well adapted to meet practical conditions of manufacture and use.

Although the present invention has been described in some detail by way of illustration and example for purposes of clarity of understanding, it is understood that certain changes and modifications may be made within the spirit of the invention and scope of the appended claims.
