GEORGE H. FRANKLIN AND HENRY G. BARR, OF PROVIDENCE, R. I.

VIOLIN-BOW.

SPECIFICATION forming part of Letters Patent No. 820,123, dated June 16, 1885.

Application filed February 510, 1885. (No model.)

To all whom it may concern:

Be it known that we, Gnonon H. FRANK- LIN and HENRY G. BARR, both of Providence, in the State of Rhode Island, have made certain new and useful Improvements in Violin- Bows; and we do hereby declare that'the following specification, taken in connection with the drawings, making a part of the same, is a full, clear, and exact description thereof.

Figure 1 is a top plan view of the frog, showing manner of and device for securing the hair. Fig. 2 is a vertical section of same. Fig. 3 is a detail of the canrrollcr and operating-lever detached. Fig. 4 is a detail end view of the bed-piece. Fig. 5 is a view of the bed-piece with the elastic cushion and end roller in place. Fig. 6 is a detail view of the elastic cushion.

The object of our invention is to produce a device by which the hair can be more firmly secured and readily adjusted, and which at the same time will from its simplicity enable unskilled or inexperienced persons to put on new hair whenever required.

In the bows now in use the hair, after being secured at the tip, has its opposite ends passed through a hole in the frog, and is secured by a pln To get the hair in even and hold it re quires so great a degree of skill that it can only be practically done by those experienced in the art.

In the drawings, A, Figs. 1 and 2, is the rod, and B the frog, which is adjusted longitudinally upon the rod A, for the purpose of tightening or loosening the hair, by a screw, D, operated by the tip 0, all in the usual way.

In our invention we mortise the frog B, and place therein a bed-piece, E, which is secured by two screws passing downward into the frog. In the bottom of this piece E we place a rubber or other elastic cushion, V, and between the perpendicular sides of this bed-piece E we place an eccentric roller, F, with suitable bearings, to which is attached a lever, G, for operating the same.

The operation of our invention is as follows: After the hair has been secured to the bow at the opposite end in the usual way, it is first passed into the mortise of the frog, and then between the elastic cushion V and the eccentric roller F and drawn taut, after which a plate or follower, 'W, is placed upon the same and forced down upon the hair through the partial rotation of the eccentric roller F by means of the lever G, as will be readily understood. The plate or follower XV upon the one side and the elastic cushion upon the other prevent the hair from being injured or cut by the operation of the eccentric roller described, and the mortise is closed by a slide, or in any other desired way.

In this device, as described, the introduction and fastening of the new hair is so easy and simple that any person using a violin can quickly and readily do the work himself, and save the expense of an experienced workman, now necessarily employed.

The plate or follower IV and the elastic cushion 'V may be either or both omitted and a fair result obtained,great care, however, being required to avoid injury to the hair from the operation of the device.

What we claim as our invention, and desire to secure by Letters Patent, is-

1. In a violin-bow, the combination, with the frog B, of a bed-piecc, E, and eccentric roller F, the whole constructed and operating to secure the hair in the manner and for the purposes substantially as described.

2. In a violin-bow, the combination, with the frog B. of a bed-piece, E, eccentric roller F, and elastic cushion V, the whole con structed and operating in the manner and for the purposes substantially as specified.

3. In a violin-bow, the combination, with the frog B, of a bed-piece, E, eccentric roller F, and the plate or follower IV, the whole constructed and operating in the manner and for the purposes substantially as specified.
