Within the upper or movable die -I Ifl'fie M is also formed a semi-cylindrical seat l9 into which is fitted a correspondingly shaped pressing die 20. The upper pressing die 20 is also formed with a flat plate member 2| having semi-circular arms 22. The upper pressing die 20 is freely mounted for rotation within its die holder Ill so that it can. readily assume different positions therein. However, the extent of movement of the pressing die 29 within its die holder I0 is limited by means of a screw 23 which passes through a slot 24in the top of the die holder II].

On the opposite side of the stationary die holder 9 from that which carries the pivot pin ii, there are provided bearings 25 for a cam shaft 26. As

clearly shown in Fig. III, the cam shaft 23 is connected at the rear of the machine to the crank arm 8 to which the previously described treadle mechanism is attached. The upper or movable die holder III is provided with a laterally projecting portion 21 formed with an interior curved cam surface as indicated at 28 in Fig. VIII. The surface 28 is so curved that with rotation of the cam shaft 25 the movable die holder I9 is forced A downward. Thus when the cam shaft is rotated in a counter-clockwisedirection, its cam 29 engages first the smoothly curved cam surface 28, and then the sharply rounded extremity 39, causing the movable die holder Ill to be forced downward gradually against the resistance of the fabric to be pressed toward the stationary die holder 9. 0n the other hand, when the cam shaft 25 is rotated in a clockwise direction, an additional cam 53 on thecam shaft 25, clearly shown in Fig. III, engages a block 64 on the projecting portion 21 of the movable die holder l0, .causing the separation of .the die holders in an obvious manner. Thus when the foot treadle 5 is pressed, the movabledie holder Ill closes upon the stationary die holder 9, but with release of pressure on the foot treadle 5, through the action of the spring 6, the cam shaft 29 is rotated in the opposite direction separating the movabledie holder II! from the stationary die holder 9.

Attached to. one of the depending arms I! of th lower pressing die 13, there is ashort link 3|. The 5 link 3| has at its upper end a slot 32 in which a pin 33 on the upper or movable die 20 is engaged. The link 3| causes the upper or movable die 20 to -be maintained in substantially Parallel relation with the lower or stationary die I3, at the limit of the separating movement. When the movable die holder III is urged downward by rotation of the cam shaft 26, its die 20 will tend to partake of the same angular movement about the pivot pin II, but will be free to adjust itself to the fabric tobe pressed. Moreover, when the movable die holder lilris raised, its pressing die 20 will tend to partakev of the angular movement of the die holder, but will be'restrained by action of. the link 3| and caused to: assume a horizontalposition. While the slot 32 of the link 3| is shown to be of elongated form, giving to the freely mounted die 29 a limited amount of play, it will be observed that at either limit of its movement the die 29 will assume a. strictly parallel relation with the opposing die l3. r

. The lower or stationary die i3 presents a flat face 34 to the companion die. 0n the flat face .34 there are depressed areas 39 shaped to the form of collar points. At the edges between the depressed areas 39 and the adjacent raised areas 36, there are right angular surfaces 35, as shown Fig. VII. The upper or freely mounted die 20 is formed with complementary raised surfaces 1 3]; adapted to fit snugly upon the corresponding depressed surfaces 39 of the lower die I 3. Thus the upper and lower dies 29 and I3 define between them a mold of the shape of two collar points. Preferably this mold is further provided with a thin flat plate 38, which in the example shown is riveted to the depressed surfaces 39 of the lower die, but which does not quite extend to the edges of the depressed surfaces 39 and hence forms recessed areas at the margins of the collar points when a collar fabric such as shown at 40 is inserted in the pressing machine. The recess'ed areas afford spaces for the accommodation .of-the extra thickness of material, as indicated at, at the margins of the collar points, so

blade or form 3, shown in Fig. I, is inserted. The

blade or form 3 is shaped to the form of the collar 49, to be pressed and fits nicelyinto the depressed areas 39 of the lower die l3. As shown in Fig.I,the blade or form 3 is adjustably supported on a metal strip which has thereon a handle portion 43, and which is bent beneath the handle portion and there joined to the guide member 4. As shown in Figs. I and V, the guide member 4 has a slotted end 44 through which bolts 45 are inserted as a means of attaching the guide member 4 to the blade carrying strip 42. By the above described connection, the vertical position of the blade or form 3 may be adjusted to suit the convenience of the operator. The guide member 4 slides withina'slot 45 at the base of the pressing machine, and at the base of the machine there is also providedan extension,

41 having a similar aligned slot for the adequate support of the guide member 4. The guide member 4 passes through the pressing machine to the rear thereof and there terminates in an upturned end 43 which carries a shock absorbing spring 49. Attached to the upturned end 48 of the guide member 4, there is a depending bracket 50 to which is connected one end of a spring 5|. The opposite end of the spring 5| is secured to the underside of the inclined table 2, as indicated at 52. 1

, It will be apparent that when the blade or form 3 is moved into the pressing machine proper I, the spring 5| is placed under tension, so that when the handle portion 43 is released the blade or form 3 will be automatically retractedv to its original position. The shock absorbing spring 49 prevents any jarring of the machine when the blade or form 3 is retracted.

As shown in Fig. H, the cam shaft 26 is provided at the front end of themachine with an additional cam 53. The cam 53 operates upon one end of a lever 54 pivoted at 55. The inner end of the lever 54 engages a pin 56 which is affixed to a movable cutter 51. The inner end of the lever 54 is attached to the end of a spring 59, the other end of which is secured to the base of the pressing machine. The cutter 51, in the example shown, is of substantially rectangular outline and is slidable vertically within a correspondingly shaped groove, clearly indicated at 59 in Fig. VI. At the top of the cutter 51 there are two projections 60 which have sharp flat cutting edges 6I which penetrate through openings 52 in the face 34 of the bottom die l3. When a collar such as shown at 40 is inserted in the pressing machine, and the movable die I9 is operated to perform the pressing operation, rotation- Gil atrthemmshaftllthronghtheactionof the lslr-allpoauseszupward invariant of the cutter llvmthecmltincedgm ii otthe'proiectinns munceaaed to the fabric and to animate These cuts or perforations are dh'eetlons of the dot-and-dash lineman: and v.

The operation of the pressing machine will be apparent from the above description. It will be especially noted, however, that the mutually opposing pressing dies I3, assume a parallel relation to each otherboth when closed and when fully separated. Accordingly, the insertion and removal of the form I which carries the fabric is facilitated, and the fabric is smoothly pressed. In operation it is not necessary that the form 3 remain between the pressing elements of the machine during the pressing operation. The operator may first apply the collar fabric to the form I, then push the form to a position between the upper and lower dies ",20. Then the operator may release his grip on the handle 43, permitting the form to be automatically retracted through action of the spring 5|. Subsequently, the operator actuates the foot treadle 5, causing the freely mounted die 2| to move downward to efiect the pressing of the fabric. At the same time the operator may use his handsto apply a new article to the form 3. Finally the operator removes the pressed article and repeats the operation on the second article.

While I have described in some details one particular example of a machine embodying my invention, it will be apparent that many changes may be made in the form of the various instrumentalities specifically shown and described herein, without departing from the spirit of the invention as defined in the annexed claims.
