COASTER FOR BICYCLES.

SPECIFICATION forming part of Letters Patent No. 604,168, dated May 17, 1898.

Application filed July 26, 1897.

To all whom it may concern.-

Be it known that I, BRADFORD I-I. DIVINE, a citizen of the United States, residing at Utica, in the county of Oneida and State of New York, have invented a new and useful Improvement in Coasters for Bicycles, of which the following is a specification.

The type of coaster heretofore used is formed by doubling a strip of metal of the required shape around the upper portion of the respective fork sides and tightening the coaster upon and around the fork side and at the same time drawing the two extremities together by means of a screw-bolt which passes through the two parts for the purpose. Inasmuch as fork sides are never of uniform sectional dimensions throughout their length, but are tapering from the fork-crown downward, and as such sectional dimensions also vary in different wheels it results not only that coasters of the above type cannot be standardized, so as to fit all fork sides whatever their relative differences in dimensions, but also that however closely the coaster is fitted to the fork side in a given case nevertheless, by reason of the said downward taper of the part to which it is applied, it is liable to slip and catch in the spokes, and thereby break the wheel and cause the overthrow of the rider.

My invention is designed to avoid the objections above referred to and to supply an economical form of coaster which may be applied with absolute permanency to every form of wheel in use. I accomplish this result by the device and attachment hereinafter particularly described, and illustrated by the drawings which accompany and are made a part of this application.

In said drawings similar letters are used to designate similar parts.

Figure I shows in perspective the forkcrown of a wheel with my coaster attached thereto. Fig. II shows in like manner the coaster when detached from the wheel.

In said figures, B is the coaster proper, which in the special form there shown consists of a single bar or plate-like piece of metal having its central portion slightly arched on the under side and of somewhat greater vertical width than the extremities or arms b b.

The longitudinal Width of said central por- Serial No. 646,057. (No model.)

tion of B should conform approximately to the longitudinal width of the fork-crown to which the coaster is to be applied. The extremities or arms I) b constitute the stirrups proper and may be of any length and dimensions desired. 0 O are inwardly-directed indentations along the upper edge of the said arms I) b and are preferably added to afford friction to the feet.

D D are straps of pliable metal having holes or perforations in the extremities of suitable size to admit the screw-bolts d d. O C, Fig. II, are nuts upon said bolts (1 d. The length of the straps D D and the distance between the said holes or perforations in the same should be such as will enable the said straps to be snugly passed over the fork-crowm from one face of the plate-like piece 13 and brought around against the opposite face thereof with the holes in the said straps registering with each other and also with a hole in the plate B.

The hole in the plate B just referred to is not shown in the drawings, but is that through which the screw-bolts d d have necessarily passed as said screw-bolts appear in the same.

In Fig. II the straps D D are represented in perspective as they would appear when conformed to the shape of a particular fork-crown and in the position for being finally fastened around such fork-crown by screwing up the nuts 0 c. In the same figure, however, the dotted lines indicate the general shape and character of one of the said straps before it has been bent around said fork-crown for the purpose referred to.

A is the fork-crown of a familiar kind, but Whether the kind be that shown in the drawings or any of the others employed in bicycles my form of coaster may be readily applied thereto by simply making the distance between the said holes in the extremities of the straps D D coincide with the distance around the crown, as described, and fastening the piece B to the crown by the straps in the manner already indicated. In the style known as the double crown, which is made up of two or more separate and parallel plates penetrated by and brazed on the fork sides, it will be found preferable to attach my coaster to the crown by passing the straps D D around the lowermost of said plates. A A, Fig. I, are the fork sides.

I do not intend to limit my invention to the specific form of device which I describe and claim in this application either with respect to the details of construction or means of attaching the coaster to a Wheel. Broadly speaking, any method of utilizing the forkcrown of a bicycle as the point of support and fastening for a bar or yoke carrying right and left stirrups for coasters comes equally 1 Within the scope of the invention.

z 5 be applied transversely to the fork sides of a bicycle above the Wheel, and, in said position, to extend beyond said fork sides, the said bar or plate-like piece being provided with metallic straps adapted to pass over or around the fork-crown of the bicycle for the purpose of securely attaching said piece to the said fork-crown substantially as shown and described.

In witness whereof I have hereunto set my hand this 20th day of July, 1897.

BRADFORD H. DIVINE.

In presence of W. H. DIVINE, GEO. IRELAND, Jr.
