EDWARD BRICE KILLEN, OF BELFAST, IRELAND.

DRIVING-BACK FOR VEII OCIPEDES, 80C.

SPECIFIGATION forming part of Letters Patent No. 636,222, dated October 31, 1899. Application filed August 15, 1899. Serial No. 727,266- (No model.)

To all whom it may concern.-

Beit known that I, EDWARD BRICE KILLEN, tea dealer, a subject of the Queen of Great Britain, residing at 38 Victoria street, Belfast, Ireland, have invented certain new and useful Improvements in Driving-Backs for Velocipedes and such Like, of which the following is a specification.

This invention relates to driving-backs for velocipedes and such like, against which the rider presses his back at the same time as he exerts the muscular force of his legs upon the pedals, so as to give additional driving power, and itis a further development of my prior United States Patent No. 615,715, issued December 13, 1898. The driving-back is adjustably secured, under this invention, by means of telescopic tubes, which are hinged to the cycle-frame at the back of the saddle.

In order that my said invention may be properly understood, I have hereunto appended an explanatory sheet of drawings, where- Figure 1 is a perspective view of a part of a cycle, showing the adjustable driving-back attached thereto. Figs. 2 and 3 are side and back views of the driving-back Fig. 1 as it appears when properly adjusted to suit the rider when traveling. Figs. 4, 5, and 6 are yviews of the cross-,bar c.

Reference is had to the drawings, whereonthe same reference-letters Wherever repeated indicate the same or similar parts.

As shown at Fig. 1, the back d is made of Wood and is held in position by means of telescopic arms d d and ff, jointed upon the pin e, and telescopic supports f f', adj ustably clamped upon the backstays A of the cycle. The arms fand supports f are pivotally secured to the back at 'L'. With this arrangement the back can be adjusted to dierent angles to suit the rider and can be set forward or moved farther back by altering the lengths of the telescopic tubes. The telescopic tubes f f take the place of the rack-arms for giving the adjustment shown and described in my prior patent. When the back is properlyadj usted to the proper distance from the saddle to suit the rider and is also adjusted Vto the proper angle of inclination, the thumb-nuts b and cessed at d" for the passage of the back wheel of the cycle and that it has also adj ustably iitted to it a cross-bar or the like c, which may be padded and which can be raised or lowered by means of a clamping-piece g and suitable screws, with nuts g, working in slots p. This bar forms a rest for the back of the rider to press against.

Fig. l shows the back in the vertical position, While Fig. 2 shows the back inclined forward to suit a rider when racing or going at great speed.

The back may be made of wood, metal, or other material, or a combination of such materials, and it may be made of any suitable size and shape.

It will be seen that not only can a longitudinal adjustment-that is, the shifting of the back nearer to or farther away from the saddle-and an angular adjustment be given to the back when made as hereinbelore described, but also a vertical adjustment (by shifting the cross-bar c up or down) and a lateral adjustment (should the back be bent or knocked to one side or other) can be effected. This lateral adjustment can be obtained by simply shifting oraltering the tubes on one side relatively with those on the other side until the proper-adjustment is obtained.

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

l. The combination with a velocipede or the like ot' a dri\fingback,upper telescoping tubes d connected to said back and to the Velocipede-frame, lower telescoping tubes f' also connected to the back and to the frame, said tubes being independently adjustable whereby the inclination of the back can be varied, and diagonal telescopic tubes f connected to the back and the frame and supporting the back.

2. The combination with a velocipede or the like, of a driving-back, telescopic'tubes extending from the back to the pin e of the cycle-frame and pivotally secured thereto, tele scopic tubes extending from the bottom of IOO ' the telescopio tubes f, f, and the telescopio 1o tubes f', f, substantially as described and shown.

Signed at Belfast, in the county of Antrim, Ireland, this 2d day of August, 1899.
