holder, by means of which the buck cover is held taut; and

Figure 12 is a view of thekey by means of which the buck cover holder of Figure 11 may be manipulated as during installing and replacing the buck cover.

Referring now to Figure l, the buck generally designated' is supported by base casting 11 on its support plate 12 by cap screws 13. Plate 12 is in turn supported by angle members 14 attached to a mounting plate 15 which is secured to the frame of a pressing machine in any conventional manner.

The pressing machine, with which this buck is used,

forms no part of this invention per se and consequently An exemplary form of pressing machine with which this buckmay be used is disclosed in our co-pending application, Ser. No. 307,456, as aforesaid. The base casting 11 of the spatulate buck 10 has a flange at 16 and is hollow inside except for an angularly disposed Web 17 which connects the side Walls. It is to this base casting 11 that the plates 18 of the spatulate form are attached bypins 19' passed through apertured washers 19A. Referring to Figure6, it is seen that these plates 18 are generally flat but are curved toward each other at the front edges 18A. The rear edges 18B of these plates are welded into longitudinal. grooves at 18C which are milled in a heavy Walled steel tube 20. The attachment of the edges 18B to the steel'tube 20 may be by welding, copper brazing or other suitable fastening means, the only essential being that the fastening be mechanically strong and capable of ready transmission of heat from the tube 20 to the plates 18.

The plates 18 are attached to the base casting by means of pins 19, and are separated by washers 19A. Plates 18 serve as supports for the tube or pipe 20. The pipe 20 is plugged at its upper end by plug 21 1 and has its lower end adjacent the lower edge of the plates 18 bent at 22 so as to extend down through the hollow base casting 11, through the hole back of web 17 therein. The pipe 20 is again bent at 23 so as to extend down between the flanges 14 as at 24 of Figure 1 so as to allow steam and condensate water connections to be made thereto.

Referring to Figure 9, it will be noted that pipe 20 extends down to a Y-connection at 25. To one branch of the Y-connection is screwed the nipple '26 which has attached to it a smaller diameter tube 28, preferably of copper, which extends all the way up the pipe 20 and terminates adjacent the plug 21 at the upper end of the pipe 20. To the nipple 26, there is attached a coupling 29, which is in turn attached to a steam connection pipe, not shown. To the other branch of the Y-conuection 25 there is attached a nipple which is connected to a suitable condensate water return, not shown. The introduction of the steam at the top of the pipe 20 adjacent the plug 21 insures that a full steam supply is made to the entire interior surface of the pipe 20fand the condensate is returned quickly and efficiently out of theipipe.

of the plates 18 are attached together by a top casting 32 which is held in place by screws 33. The construction of one type of top casting is described in our copending application, Ser. No. 145,258, now Patent No. 2,687,241. The top casting may be of any desired type as to facilitate the sleeving of a tubular form onto the spatulate buck, and forms no part of this application per se.

While this invention has been described with reference to a vertically positioned buck for use With tubular garment sections, it is to be understood that it may likewise be used with reference to a horizontally positioned buck for tubular garment sections or to horizontally or vertically positioned bucks for use with other, garment sections.

Referring to Figure 8, it Will be noted that by milling the groove 18C to approximately the thickness of the plate 18 a smooth outer surface is produced at the junction of the plates 18 and the tube 20, plates 18 being easily ground off and polished, if desired. Upon the smooth exterior surface thus formed by the two plates 18-18 and the tube 20, there is mounted a suitable buck padding of one or more layers 31 and 34. The layer 31 is preferably made of cloth knitted from rust resistant Wire, such as Monel metal, or the like, the pad being composed of a plurality of plies of such fabric. Upon such resistant woven metallic pad 31 is preferably laid a pad 34 comprised of one or more layers of flannel and over this there is tightly stretched the exterior buck cover 35. Experience has shown that for the average surface encountered in presses of this type, that the buck cover 35 should best be made with very tough fabric, such as nylon fabric.

The attachment of the nylon cover 35 is accomplished in the following way: The nylon cover has its opposite edges sewed so as to form headings 38 and 39 in which there are placed thin, flat, comparatively narrow steel rods 40 and 41. At the upper and lower ends of the space between the steel side plates 18 there are provided brackets 42 which have holes 43 longitudinally therethrough which serve as sliding supports for rods 44. At the rear ends of the rods 44, there are washers 45 held in place by'the cotter pins 46. To the front ends of each of the rods 44, there is attached a T-shaped head 48 having a hole 49 therein. The spring 50 is pressed between the bracket 42 and the washer 45 and tends to draw the rod 44 back in the direction of the arrow 51, as shown best in Figure 10. The T-shaped heads 48 have a thickness such that when they are turned so that the head lies parallel with the plate 18 the shoulders 52 and 53 will be disengaged from the ends of rods 40 and 41. In order to place the buck cover on the buck padding, the fabric 35 is pulled as tautly as possible by, hand over the buck padding and the two rods 40 and 41'are then tucked back It was found by lengthy experiments that thcheating of I the pipe 20 with high pressure steam provides adequate heat for the elimination of Water from the buck pads even at high rates of ironing production and with damp shirts, it was found also that by having theplates 18 welded or otherwise firmly connected to the-pipe 20, that Th'eiupperuendsa long shank 54, a turned over end-55 and a handle 56.

The shank 54 is inserted into the space between the front edges of the buck padding and the plates 18 until the hook end 55 can be'engaged in the hole 49 of the T-shaped head 48. The head is then drawn forward until it clears I the rods 40 and 41 and is then turned so that the shoul the heat is conducted adequately throughout the area of the plates 18 and hence given off on the surface ofthe' ders 52 and 53 engage grooves in the ends of rods 40 and 41, respectively. Then the T-shaped head 48 is permitted to be retracted under the influence of spring 50 and this throws a tensioning pressure on the rods 40 and 41, which accordingly draw the nylon fabric 35 closely and tautly over the buck padding.

It will be noted, from Figure 10, that over the front edges18A of each of the buck plates, there is a small member generally designated 58 which has a flange 59 also toembrace the front curved-in tip 18A of'the plate 18. The member 58 is a light stainless metal and is curved to fit the front bend 18A of the plate 18. Howing thereof.

arm 69 and alower crank, arm 70. Bellcrank lever 68 is pivoted at the pivot 71 for arcuate movement. This bell-icrank lever. arm 69. which extends; upwardly 1 between the plates. 18 andthespatulatebuckstructure, has spaced members and carries .pivot 66.. upon which the'slotte'd lug 64 is hung. The lever arm 69 extends down between the plates 1818 and is bent so as to operate within the front opening in the base casing 11 and then extends downwardly to the pivot 71 whence it extends V forwardly at the portion 70. This forward portion 70 said co-pending divisional application. Since such adjustment rod and the wing structure form no part of this invention per se, they will not be described in greater 'detail. The pivotal mounting of the bell-crank lever arm 68 upon pivot '71 and the provision of pivot 75A allows attachment to pivot 75 of a link not shown which may be operated to propel the buck-wing outwardly (leftwardly with reference to Figure 3). The provision of operator actuable rod 76 likewise allows this to be done selectively at the operators discretion.

It will be noted from Figure 1 that the upper end of the buck is narrower than the lower end and that the upper end is cut square whereas the lower end of the buck, corresponding in the illustration of the shoulder seam of a shirt sleeve is at an angle. Thus, referring to Figure 1, the buck, generally designated 10, has a smaller front to back dimension at its upper end than at its lower end and the padding is at substantially right angles to the longitudinal axis of the buck at the upper end A .but is shaped at the angle along the lower end 10B. It will be understood, however, that the shape of the buck may be varied to accommodate the pressing of difierent shapes of garment elements. A.

As many widely diifering embodiments of this in'vention may be made without departing from the spirit and scope thereof, it is to be. understood that we do not specifically limit ourselves to the embodiments disclosed herein.
