T0 at whom it may concern;

Be itknown that I, LEWIS KINTZ, a citizen of the United States, residing at Cumberland, in the county of Allegany and State of Maryland, have invented certain new and useful Improvements in Brakes, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to a new and useful improvement in brakes especially designed for use upon the wheels of bicycles and similar vehicles and its object is to provide a neat device of simple and economic construction, effective in operation, and which may be readily attached to or detached from the frame of the machine.

Heretofore brakes of this character have been made of separate pieces 'of metal and rigidly secured to the under surface of the crown of the forks by means of screws, &c., or by means of bands laid over said crown and riveted or otherwise rigidly secured at the ends to the body of the brake. This form of brake has been found objectionable in many ways, especially in view of the difliculty experienced in applying the same to the ma chine, as well as its weakness at the points of connection of the parts.

My invention consists in forming the brake and its securing means of one continuous piece of metal, which may be struck up from a single blank.

It also consists in the further novel constructions and combinations of parts hereinafter more fully described and claimed, and illustrated in the accompanying drawings, showing the preferred form of my invention, and in Which- Figure 1 is a perspective view showing my improved brake applied to a bicycle. Fig. 2 is a detail view thereof detached. Fig. 3 is a plan view of a blank prior to being bent into proper form, and Fig. 4 is a detail view of a modification.

Referring to said figures by letters of ref erence, A is the body of the brake, which is shown preferably curved in cross-section to conform to the under surface of the arched fork-crown a, as well as to overcome any tendency of this part to spring or give when placed under pressure. Said body portion is provided with an extension or shoe B, en' larged and recurved near its end and prefer ably provided with laterally-extending serrated foot-pieces O of suitable size, and intermediate said body portion and shoe the brake is preferably substantially fiat, as at A, to enable the said shoe to spring in a vertical direction. Extending longitudinally from and formed with the opposite or forward end of the body A are preferably two arms D, each perforated near its outer end, as at d, for the reception of a bolt, as E, or other suitable device.

In applying the brake to the machine the body A is inserted beneath the crown a of the forks. over the crown and to either side of the steering-head a, and the bolts are placed within the perforations dand similar holes d, formed in the body of the brake. Nuts, as E, may then be screwed upon the lower threaded ends of the bolts, and the bands D can thus be quickly tightened upon the crown. The brake may then be operated by pressing with the foot upon one of the foot-pieces O, causing the shoe to come into frictional contact with the tire of the wheel. It is obvious that said shoe will spring up to its normal position as soon as pressure is removed therefrom.

In Fig. 4 I have illustrated a modified form of my brake. In said figure the bolts F are shown as formed of extensions of the arms D. It is obvious that these bolt extensions F may also be threaded to receive nuts after being inserted into the perforations 01.

While in the foregoing description I have Arms D are then sprung back shown the preferred form of my invention, I

do not limit myself thereto, as I am aware.

that modifications may be made therein without departing from the spirit or sacrificing the advantages thereof, andl therefore reserve the right to make such changes as fairly fall within the scope of my invention.

Having thus fully described my invention, what I therefore claim as new, and desire to secure by Letters Patent thereon, is-

As a new article of manufacture, a brake struck up from a single piece of metal and comprising an intermediate portion arched in cross-section whereby .it may fit snugly against the under surface of the crown of a too ve1ocipede,a fiat body portion extending from clamped intermediate the arms and said archthe arched portion and having foot-pieces shaped portion, substantially as described. 10 thereon, bow-shaped arms formed on the end In testimony whereof I affix my signature of the intermediate portion and recurved in presence of two witnesses.
