MACHINERY FOR ROUNDING LEATHER STRINGS.

SPECIFICATION forming part of Letters Patent No. 250,516, dated December 6, 1881.

Application filed May 21, 1881. (No model.)

I 0 all whom it may concern Be it known that I, WASHINGTON FOGLE- SONG, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented a new and useful Machine for Rounding Leather Strings, of which the following is a specification.

My invention relates to a machine having two rollers, one having a series of grooves, the bottoms of which forming semicircular faces, and the other having a corresponding series of flanges, which enter said grooves with like faces, the said races being equidistant from their axes. At the point of intersection these faces are moved together at a uniform speed by means of two cog-wheels of equal diameter attached to the axles of the rollers. The semicircular facrs, where contiguous, form a circular orifice, through which the leather strips are carried by adhesion to the rolls, and thus are formed round strings in an expeditious manner.

The mechanism is illustrated in the accompanying drawings, in which Figure I is a fi out elevation of the leather-string machine. Fig. 11 is a transverse section of the rolls through the groove and flange. Fig. III is a rear view of the guide-plate.

A represents a substantial cast-iron frame with two uprights. In central cavities of the uprights are placed the ordinary form of boxing, which forms bearings for the axles of the rolls. Screws enter the upright over the box ing, for the purpose of adjusting the rolls and holding them in proper relation.

On the top of the uprights is attached a thin plate, 112, of steel, which has projections entering the grooves to force the leather string out of the same. Attached to the bottom is a similar plate, n, which covers the flanges and cleans them of any portion of leather which may adhere to them.

The roll B is cylindrical in form, and has a series of grooves cut in its periphery, with parallel sides, terminating in semicircular bottoms or faces. It is supported in bearings, as before described, and external to the frame has attached a cog-wheel, O, which gears into another of equal diameter, which is attached to the axle of the roll B. This roll has a series of flanges with parallel sides, terminating in semicircular faces. These flanges enter the grooves of the upper roll, and thus form a circular orifice, through which strips of leather are passed for the purpose of rounding the same. The rolls are of equal diameter at their semicircular faces and rotate in opposite directions. The sizes of the holes formed between the rolls vary slightly in size.

F is a guide fitted closely to the rolls, and is attached to the frame. The position and size of the horizontal holes through the same correspond to the position and size of the circular grooves of the rolls.

The machine may be driven by power or hand, and when driven by hand the Wheel D is attached to the axle of the lower roll, a suitable handle being attached to the same.

The operation is thus: The leather is cut in strips of uniform width. An end being placed in the largest hole of the guide, the rolls are turned, and when the end is far enough through it is entered in the second hole and again in the third hole, and when the strip has thus passed through the machine it is uniformly round and smooth.

I do not regard my invention as confined to rolls having a series of orifices, but one or any desirable number which may prove advantagnous.

The machine may be varied in other particulars, the essential feature being the semicircular faces of the grooved and flanged rollers.

Having thus fully described my invention, What I claim, and desire to secure by Letters Patent, is-

1. The roll B, having a series of grooves terminating in semicircular faces, with flanges of roll B snugly entering the said grooves, the said flanges terminating in corresponding faces, thus forming a circular orifice between said faces, substantially as and for the purpose set forth.

2. The rolls B B, constructed substantially as set forth, in combination with the frame A, cog-wheels 0, plates at and. n, and guide F, substantially as set forth.
