COLLAR-CREASING MACHINE.

SPECIFICATION forming part of Letters Patent No. 557,766, dated April 7, 1896.

Application filed October 26, 1895. Serial No. 566,940. (No model.)

To all whmn it may concern.-

Be it known that I, CLARENCE LEE BURGES, a citizen of the United States, residing at W'orcester, in the county of lVorcester and State of Massachusetts, have invented a new and useful Improvement in Collar-Creasing Machines, of which the following is a specification.

The object of my invention is to provide a strong, simple, and eiiicient machine for creasing collars.

To these ends my invention consists of the parts and combinationsof parts, as hereinafter described, and more particularly pointed out in the claims at the end of this specification.

In the accompanying drawings, Figure 1 is a front view of a collar-creasing machine constructed according to my invention. Fig. 2 is a transverse sectional view of the same, and Figs. 3 and 4: are detail views illustrating the operation of the device.

A collar-creasing machine constructed according to my invention comprises a grooved creasing-roller and a disk secured upon parallel shafts, which are so mounted in the framework of the machine that they can be moved into and out of engagement.

Referring to the drawings in detail, designates a suitable pedestal or support. Fastened upon and carried by the pedestal 10 is abed-piece or casting 11. J ournaled in the bed-piece 11 is a driven shaft 12, carrying a pulley 13, a pinion or gear-wheel lat, and a grooved creasin g-roller 15. The grooved roller 15 is cored out or made hollow to cooperate with a burn er or j et-pipe 16. The burner 16 is supplied with a mixture of air and gas by means of the pipes 17 and 18, which are controlled by means of suitable valves, as shown. Projecting from the front face and preferably formed integrally with the grooved roller 15 is a bending section or roller 19. Mounted in the bed-piece 11 and arranged to move in suitable guideways is a verticallymovable box 20. J ournaled in the vertically- A bolt 21, threaded into the frame of the machine, is provided with a check-nut and forms an adjustable stop to limit the upward movement of the box 20. A feed-roller 26 is journaled on an extending arm in position to cooperate with the creasing-disk 23 when the same is moved to its highest position. The feed-roller 26 is preferably covered with felt or other flexible material. The vertically-movable box 20 and the parts carried thereby are normally held in their lowest position by means of a spring 27, mounted on a vertical rod 28. The rod 28 is connected at its lower end to a treadle 29, which may be arranged or mounted in any desired manner.

The operation of my improved collar-creasing machine as thus constructed is most clearly illustrated in Figs. 3 and 4. A collar which is to be folded or creased is placed in position upon the disk 23, and the treadle is operated to bring the creasing-disk 23 and roller 15 into engagement and the gears 22 and 14 into engagement. The collar will then be'fed forward by the action of the creasing disk and roller and by the supplemental action of the feed-roller 26, so as to be properly creased or turned down. It is to be noted that the grooved roller 15 is considerably larger as compared with the disk 23 than the gear or pinion 14: as compared with the gear By means of this arrangement the peripheral speed of the grooved roller 15 will be considerably greater than that of its cooperating disk 23. I have found that this is an important pointin practice, as the grooved roller 15, which acts upon the exterior surface of the collar, will have a certain slip or drag over the surface of the collar and will impart a desirable polish or finish to the same. The pressure exerted between the creasing disk and roller can be accurately regulated by means of the adj ustable stop 2 L and its check-nut 25. After a collar has been passed between the creasing disk and roller it can be bent to the desired curvature by wrapping the same around the bending roll or section 19, as illus trated in Fig. 4:. One especial advantage in constructing my collar-creasing machine so that the creasing disk and roller are normally out of engagement resides in the fact that by adopting this arrangement my machine may what are known as be used for creasing In this class of colrolled-front collars. lars only the middle or rear section of the collar is brought to a sharp crease. lVh en a collar of this class is to be creased or finished, the collar is inserted some distance between the creasing disk and roller before the same are brought into engagement, and the disk and roller are separated before the end of the collar is reached,thus preserving the roundedoyer effect which is desired in this class of work. By using a tapered disk 23, as shown in the drawings, the work can be nicely laid in position thereon, and there is very little danger of the hands of the operator being caught between the creasing-surfaces.

The machine constructed according to my invention may be employed for turning down the points of standing collars and for other purposes which will be obvious to those who are familiar with the ordinary forms of laundry-work and need not be herein set forth at length.

I am aware that changes may be made in the construction of the machine by those who are skilled in the art and that certain features may be used in different locations and in different combinations without departing from the scope of my invention as expressed in the claims. I do not wish, therefore, to be limited to the construction which I have shown and described; but

lVhat I do claim, and desire to secure by Letters Patent of the United States, is

1. In a collar-creasing machine, the combination of a bed-piece, a driven shaft 12 journaled in said bed-piece, a gear and grooved roller secured upon said shaft, said grooved roller being cored out or made hollow, an exterior heating device, as 16, a vertically-movable box mounted in suitable ways in said bed-piece, a shaft 21 journaled in said box, a gear and creasing-disk secured upon said shaft, and a treadle for moving the shaft to bring the gears and creasing disk and roller into engagement, substantially as described.

2. The combination of the creasing roller and disk, means for bringing said disk and roller into and out of engagement, and a supplemental feed-roller j ournaled upon avertical axis in position to cooperate with the disk, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses,

CLARENCE LEE BURGES.
