SUPPORTING- -CLIP FOR BRAKE-ARMS OF BICYCLES.

SPECIFICATION forming part of Letters Patent No. 534,846, dated February 26, 1895.

Application filed June 15, 1894.. Serial No. 514,706. (lilo model.)

To 00% whom it may concern.-

Be it known that I, FREDERICK J. STIMSON, a citizen of the United States, and a resident of the city of New York and State of New York, have invented a certain new and useful Improvement in Supporting-Clips for Brake- Arms of Bicycles; and I do hereby declare the following to'be a full, clear, and exact description thereof, reference being had to the accompanying drawings, forming part of this specification. 7

My invention has relation to a certain new and useful improvement in clips or attachments to bicycle brakes, and substantially consists in the construction hereinafter particularly described and claimed.

The object of my invention is to provide a construction of clip upon which the pivoted brake arm may be secured to the bicycle without liability of becoming pinched or bound by the clip while at the same time the clip may be most rigidly secured to the handlebar or framework of the bicycle.

In the accompanying drawings, Figure 1 is a perspective view of a clip detached with a section of the brake bar indicated in position in dotted lines. Fig. 2 is a longitudinal sectional view of the clip, and Fig. 3 represents the clip in position upon the handle-bar supporting the brake-arm.

The clip is composed of two main sections,

A, A, each of substantially similar construction placed opposite each other invertedly as shown in the accompanying drawings. Each of the castings, A, A, is provided with an upper arm, a, curved preferably in the arc of a circle to fit over the rounded handle-bar, and a lower depending arm, 0/, preferably recessed, the construction being such that when in position the upper arms, a, form around and bind upon the handle-bar of the bicycle, while the construction of the lower arms, a, provides a recess between them for the reception of the main brake arm, I), the width of the recess, when the two parts are secured in position upon the handle-bar, being preferably slightly greater than the width of the brake arm.

As a means of securing the clip upon the handle-bar a keyed screw-threaded bolt, or

thumbscrew, D, is screwed into one of the castings, as A, and carries the other casting, A, loosely upon it through the medium of the collar, d. In this manner the clip may be readily adjusted upon the handle-bar, or other parts, of varying diameters, or sizes, and the clip will be rigidly and immovably secured by the tightening of the bolt, D. In order to prevent the lower arms, a, from impinging and binding upon the sides of the brake arm, I), when pivoted in position between them, I provide through the brake arm a distanceregulating pivot, E, horizontally adjustable in and between the said arms, a, to the end that the arms may be positively separated by proper adjustment of the pivot, E, and prevented from impinging, as when the adjustment of the upper arms, a, upon the handle bar would tend under certain conditions to have that effect.

The distance-regulating pivot, E, is adjusted in a screw-threaded orifice in one of the downwardly projecting arms, Cb, as the arm of the section, A, while the opposite end is adapted to bear in a recess or depression, 0, provided in the other downwardly projecting arm, which recess also forms a bearing for the outer end of the pivot, E, which is subjected to more or less strain in the operation of the brake-arm. In this construction the downwardly projecting arms, a, supporting and inclosing the brake-arm may be maintained at any desired distance apart to prevent the brake-arm from binding, as when the clip is rigidly secured to the handle-bar, which thus allows at all times a free and easy movement of the brake-arm. Further it is clear from the construction that the operation of the brake-arm cannot tend to loosen the securing bolt, D; and also that the outward strain upon the arms, a, occasioned by the bolt, E, tends not only to separate the arms, a, but also to assist in locking the bolt, D, in the combined sections.

I am aware that numerous other constructions of supporting clips for brake arms, and for other parts, have hereto fore been invented, and do not claim the same broadly, my invention residingmainly in the construction of device herein particularly claimed.

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

1. A securing clip consisting of two independent sections each having upper inwardly protruding recessed gripping jaws, a transversely disposed screw-threaded bolt provided through said sections, depending perpendicularl y disposed arms parallel with each other at a distance from each other forming a recess between said depending arms and adjustable threaded pivot transversely disposed through one of said arms and through said recess having its inner end impinging against the opposite depending arm for regulating the distance between said arms and for carrying the brake-arm, substantially as described.

2. A securing clip consisting of the sections, A, A, gripping arms or jaws, a, downwardly projecting arms, a, transversely disposed securing bolt, D, having threads upon its outer end engaging with a screw-threaded orifice in one of said sections, as A, and protruding through the inner section for securing the clip to the frame of the machine, and screwthreaded distance regulating pivot, E, carried in one of the arms, a and impinging against the opposite arm for spacing said arms, substantially as described.

3. A securing clip consisting of the sections, A, A, oppositely disposed gripping arms, a, downwardly projecting arms, a, perpendicularly disposed at a distance from each other forming an intervening recess, transversely disposed screw-threaded securing bolt, D, provided in a screw-threaded orifice in the section, A, loosely carrying the inner section, A, and collar, d, provided upon said bolt, D,impinging against the outer surface of the section, A, transversely disposed distance-regulating pivot, E, screw-threaded at or near its outer end and provided in a screw-threaded orifice in the section, A, and recess, 0, provided in the arm, a, of the section, A, for the reception of the inner end of the pivot, E, substantially as described.

In witness whereof I have hereunto set my hand this-12th day of June, A. D. 1894.

FREDK. J. STIMSON.
