I To all whom 'it may concern:

Be it known that I, JAMES K. P. PINE, a citizen of the United States, and a resident of Troy, in the county of Rensselaer and State of New York, have invented. certain new and useful Improvements in Machinesv for Bending Collars and the Like, of which the following is a specification.

My invention relates to a machine for bending starched articles, and more particularly a machine for folding or bending the corner of a collar, cuff or similar article. Mens linen collars of the wing or wingpoint form are ordinarily laundried flat, and the win or corner is'afterward bent outward. n account of the stiffening of the collar by the starch therein, the material is very likely to crack along the line of fold.

My device is a novel machine for bending starched articles such as wings of collars and it also provides novel means for dampening the collar to a sufficient extent before or as it is folded, and means for adjustment so that collars of different sizes and patterns may be folded on the same machine.

In the drawings, Figure 1 is a plan view of a machine embodying my invention. Figs. 2 and 3 are side elevations o1 the opposite sides thereof. Fig. 4 is a partial end elevation showing the fold producing device. F ig. 5 is an end elevation of the part shown in Fig. 4. Figs. 6, 7 and 8 are partial end elevations on an enlarged scale of the fold-producing portion of the device,

showing its different positions. Fig. 9 is a partial end elevation showing the support for the article to be folded. Fig. 10 is a planv view `of the same. Fig. 11 is a similar Fig. 12 is a partial detail plan View of a heating device. Fig. 13 is a partial diagrammatic plan view showing the gage portion of the device.

I will rst describe a particular form of machine constituting one embodiment of my invention and will afterward point out the novel features in the claims.

4Broadly speakingmy machine for producing a bend in starched fabric articles contemplates first a member having an edge over which the article may be bent, said edge' corresponding withgthe line of the bend. Second, a bending device for coper- `ating with said edged member upon both sides of the edge of the latter, preferably comprising for example a pair of rollers, one of which may pass on one side and the other on the other side of the edge when an article is being bent. Third, a mechanism for producing relative movement between said first and second elements so that on their relative approach the fabric may be bent about the edged member and on thc separation or relative movement from each other, the article maybe released to permit its removal and the insertion of a new one; this mechanism acting preferably upon the bending device only so as to cause it to approach and recede from the edged member. In connection with the above principal elements, I also preferably provide heating means such as passages for steam circulation by which the edged member or the bending device may be maintained in highly heated condition, which would be important in bending the wings of wing collars. Also an apparatus by which the starch of the starched article may be moistened so as to break the starch along the apex of the edged member previously to its bending; and the action thereof should be such that the moistening ceases as or immediately before the bending takes place in order that the bending may be in the nature of an ironing action and leave the finished article without any moisture. To this end my invention in its preferred form contemplates also such an apparatus that the starch breaking medium or steam can be intermittently applied along the edge to be bent, and this intermittent action 1s secured automatically in the specific form of machine illustrated in the drawings, through the agency of appropriate mechanical connections. Other preferred features or details will appear in the following detailed description, which as previously stated discloses but one of many forms which my improvements may assume.

1 designates the base of the machine, from which rise standards 11, 12, 13 and 14. The standards 1l are provided with suitable bearings 15 for a shaft 16, on which is a pulley 17 connected by a belt 18 to any source of power. Mounted on the shaft 16 is a cam wheel 2, on one side of Which is an approximately triangular cam groove 21 and a cam 22, (see Fig. 2), and on the other side of which is a cam groove 23 and a cam surface 24, to be hereafter described, (see Fig. 3). Suitably supported on the base 1 is a support 3 for the article to be folded. This is shown as a hollow chamber flared at its top and having an edge 31 formed with a slot 32 (see Fig. 10), or in the modified form shown in Fig. 11, formed with. a plurality of apertures 33. To the chamber of the support 3 leads a pipe 34 which is connected with a supply of steam or other suitable dampening medium. In the pipe 34 `(see Fig. 3), is a valve 35 having a handle lever 36 pivotally secured to a block 37, which is apertured to slide freely on a rod 33. On the rod 38 are set collars 39, one at each side of the block 37 .Y One end of the rod 38 is pivoted at 310 to a lever 311 pivoted at 312 to the standard 14. vAt the other end of the lever 311 is a pin 313 which may advantageously be provided with a roller, and which moves on the cam surface 24 on the cam wheel 2. As shown, the support 3 is provided at its upper corners with upwardly extendinglugs 314, (see Fig. 9). Pivoted on the standard 13 is a lever `4, at. one end of which is a roller pin 41 ruiming in the cam groove 23, Fig. 3. The other end of the lever 4 is connected by a link 42 to a lever 43, the end 44 of which is bifurcated to pass over and be guided by the shaft 16, Fig. 2. YOn the lever 43 is a roller pin 45 engaging in the cam groove 21. At the other end of the lever 43 is a socket 46, in which is adjustably mounted by means of a pin 51 a yoke 5, to which is pivoted a cross bar 52, Fig. 4. A Hat spring 531 is shown as secured on the upper side of the yoke 5, and as having its free squared end bearing on the upper face of the bar 52. At the ends of the bar 52 (see Figs. 6, 7 and 8), are flat springs 53 having at their free ends lugs 54 forming bearings for the parallel shaft-s 55 of two rollers 56, Fig. 5. The ends of the shafts 55 are connected by links 57 pivoted together by a shaft 58. Ratchet wheels 59 secured at the end of each of the shafts 55 engage with oppositely disposed dogs 510 pivoted on the spring straps 53 and maintained in engagement by flat springs 511. Pvoted on the standard 12 isa lever 6, one end of which is provided with a roller pin 61 adapted to coperate with the cam 22 on the cam wheel 2. At the other end of the lever 6 is a forked portion 62, which passes between the strap springs 53 and is adapted to bear against the pivot shaft 58. This forked portion of the lever or bar 6 is beyond the point where said bar Vis pivoted, and as seen in Fig. 1 is preferably made with two branches by reason of the bar being forked at this point. The forked bar portion 62 is extended as explained between the springs 53 and in such a position that when moved downwardly the branches thereof will press the shaft 58, causing the links 57 to act as a toggle to separate the rollers 56 and release the collar. The forked portion 62 is given such length that when the rollers are shifted from the idle position of Figs. 1, 2 and 3 to aposition above the support 3, the portion 62 will still be in proper relation for actuating the links 57 to separate the rollers. Passing through suitable apertures in the standard 12 are gage rods 7, the free ends 71 of which are 11p-turned, the rods 7 extending at each side of the support 3. The rods 7 are made longitudinally adjust-able in the standard 12 by set screws 72. Connected with a gas supply is a ,pipe 8, the end 81 of which is provided with gas emission apertures 82 (see Fig. 12), and is placed as shown in Figs. 2 and 3 of the drawings for a purpose to be hereafter described.

The operation of my device is as follows The collar 9 or other article to be folded is placed on the edge 31 of the support 3, the upper edge of the body of the collar bearing against the upturned end 71 of the gage rod 7, and the lug 314 on the support 3 engaging in the corner of the collar between the nose 91 and the wing 92. It is obvious that the gages 7 may be so set as to bend a corner 92 of any desired size and shape. By providing the gages 7 and lugs 314 in duplicate, both corners of the collar may be bent, as indicated in Fig. 13. The machine standing in the position indicated in Figs. 1, 2 and 3 of the drawings, is then started, when the levers 4 and 43 act to move the rollers 56 toward the edge 31 of the support 3, and then downward over the edge and over the collar 9, as shown in Fig. 6. The further movement of the machine raises the rollers 6 off the support 3 with the collar inclosed between them, as shown in Fig. 7. Vhen the shaft 58 rises to the position shown in Fig. 7 it is forced by the quick downward movement of the forked end 62 of the lever 6 so as to spread the rollers apart (see Fig. 8). This releases the collar and permits the operator to remove it. The cams on the cam wheel 2 are so timed that immediately before the bending action of the rollers is applied to the collar, the valve 35 is opened and then immediately cut off so as to permit a small quantity of steam to pass out of the apertures 32 or 33 to moisten the collar so as to prevent its cracking during the folding operation. By properly adjusting the set collars 39, the time of the steam admission and cut-olf may be regulated as desired, but practically the steam should be cut off as the bending takes place, that is, not later than the actual bending, since the article is to be left dry. By this I mean it may be before the bending takes place if it be immediately before, not long enough before to permit the collar to dry or the starch to stiffen before the bending. When the rollers 56 are moved away from the support 3 and returned to the position shown in Figs. 1, 2 and 3 of the drawings, they are located immediately lover the gas apertures 82 in the pipe end 81, which dries the rollers yof any superfluous moisture. By reason of the pivotal motion of the bar 52 on the yoke 5, which motion is controlled and limited by the spring 531, any slight adjustment of the downward movement of the rollers over the collar is made bythe support 3. This is advantageous particularly when the wing of the collar or other article to be folded is of fewer plies than the body of the collar.

It is `obvious that many mechanical changes may be made in my device without departing from my invention, and that parts of the ydevice may be used without others.
