BICYCLE-BRAKE.

SPECIFICATION forming part of Letters Patent No. 484,953, dated October 25, 1892.

Application tiled March 28, 1892. Serial No. 426,776. (No model.)

T0 @ZZ whom it may concern:

Beit known that I, RIMMON O. FAY, of Ilion, in the county of Herkimer and State of New York, have invented a new Improvement in Bicycle-Brakes; and I do hereby declare the following, when taken in connection with accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and. which said drawings constitute part of this specification, and represent, in-

Figure l, a View in vertical section through the handle-bar and steering-head of a bicycle provided with a brake constructed in accordance withmy invention; and Fig. 2, a detached broken view in inside elevation of the handle-bar and its perforated sleeve, showing, also, the operatingdever of the brake.

My'invention relates to an improvement in brakes for bicycles, the object being to produce a simple, durable, and eective brake which shall be for the most part concealed and inclosed, whereby the appearance of the machine is improved and the brake protected against accidental injury.

With these ends in view my invention consists in a device having certain details of construction and combinations of parts, as will be hereinafter described, and pointed out in the claims.

As herein shown, the steering head A of the bicycle is supported by tubes B B, connected with it near its upper and lower ends and forming parts of the frame of the machine. The lower end of this head receives the steering-fork O, which embraces the steering-wheel D, while its upper end receives the vertically-adjustable sleeve E of the handlebar F, which is secured to the upper end of the said sleeve.

The operating -lever G of my improved brake is constructed to extend out under one of the handles of the handle-bar, so that it may be readily manipulated by the fingers of the riders hand without the removal of the same from the handle. This lever is pivotally suspended from the bar near its inner end, as at G', and provided at its extreme inner end with a yoke G2, which is connected by means of a pin g with the upper end of a threaded adjustable rod I-I, located within the said sleeve, which is provided at its upper vend. with a vertical slot e, affording clearance for the pin g, before mentioned, as the rod is lifted up and down. The said sleeve E is constructed with a vertical series of holes e', formed in its inner face to receive the inner end of a screw A', mounted in the extreme upper end of the steering-head and entering the said perforations for the purpose of sustaining the sleeve, and hence the handle-bar,in any desired position of adjustment. The lower end of the rod H is threaded and screwed into a nut I, secured within the upper end of a coupling-tube I', which is located within the lower end of the said sleeve, and provided at its eX- treme lower end with a circular guide-block I2, fitting within the steering-head and vertically movable therein and receiving a horizontal pin t', which eXibly connects the upper end of the brake-rod J with the said block, and hence with the coupling tube and rod H. The lower end of the said rod .l has bearing in the plug C, forming the upper end ot' the steering-fork O, and shaped to enter the lower end of the steering-head, the said end of the brake-rod having the brake-shoe K attached to it, whereby the said shoe is located within the upper end of the fork directly under the steering-head and in close proximity to the steering-wheel D. A spiral spring L, encircling the rod J, is interposed between the block I2 and the plug O and arranged to eX- ert a `constant eort to lift the brake-shoe into its retired position, in which it is shown by the drawings, and in which it clears the wheel. It will be seen that the adjustable rod H, the coupling-tube I', and the brakerod .I form a longitudinally-adjustable connection between the brake-lever G and the brake-shoe K, there being a necessity for a longitudinal adjustment in this connection to accommodate the vertical adjustment of the sleeve E, carrying the handle-bar F. To make the said adjustment, the adjustable rod H is screwed in or out of the nut I, located in the upper end of the coupling-tube, accord.- ing as the sleeve E is adjusted to raise or lower it. If desired, the place of the nut I might be taken by threads formed directly in the upper end of the coupling-tube.

It will be noticed that most of the members IOO of my improved brake are located within the steering-head and the sleeve of the handlebar, whereby they are obscured from sight with manifest improvement in the appearance of the machine, and whereby they are protectedagainst accidental injury in case the machine receives a fall or other'rou'gh treatment. The described arrangement of parts also secures a direct acting and efficient brake. 4 l

I would have it understood, that I' do not limit myself to the exact construction herein shown and described,- but hold myself at liberty to make such changes and alterations therein as fairly fall Witliin' the spill-it and scope of my invention.
