VELOCIPEDE on CYCLE PEDAL.

SPECIFICATION forming part of Letters IPatent No. 548,042, dated October 15, 1895.

Application filed May 14, 1895. Serial No. 549,291. (No model.) Patented in England October 19, 1892, N0.18,678.

To all whom it may concern.

Be it known that I, AUGUSTINE CAMPBELL DAVISON, a subject of the Queen of Great Britain, residing at Holloway, in the county of Middlesex, England, have invented a certain new and usefullmprovement in Velocipede or Cycle Pedals, (for which I have received Letters Patent in Great Britain, No. 18,678, dated October 19, 1892,) of which the following is a specification.

This invention relates to velocipede or cycle pedals of that class commonly called rattrap pedals. As usually constructed prior to this invention, such pedals consisted of one or more surfaces adapted to receive the foot, such surfaces being serrated or roughened and supported at their ends by cross-pieces carried by the pedal bar or pin. The end pieces usually extend beyond or above the level of the foot-piecesin order to prevent any liability of the foot slipping ofi. In practice I have found that except such foot pieces or plates are of very considerable strength and appreciable weight they are extremely liable to be seriously bent and even broken, owing to the pressure applied by the foot between the end pieces or points of support if the foot is accidentally placed upon the flat side of the bar. To obviate this drawback, according to my invention, I propose to place the supporting-pieces between the foot-plates instead of at their ends and so close together that they would under such circumstances take the direct thrust to the pedal bar or pin, and in lieu of such pieces forming end or side guides to prevent the foot from slipping ofi the side, I propose to turn up the ends of the foot-pieces to form such guides or stops.

In order that the invention may be clearly understood, reference is made to the accompanying drawings, in which Figure 1 represents in side elevation a pedal constructed in accordance with this invention and in position to receive the foot upon its top facet Fig. 3 is an end view.

In said drawings, A A are the rat trap bars or plates turned up at their ends a a.

B B are the supporting pieces or plates,

Fig. 2 is a plan view of same, and

placed so closely together as to be practically about or slightly less than the width of an ordinary shoe-sole. The ends of B pass through plates A, to which they are riveted or secured, as indicated at b.

C C are the ball-cases, which may, as usual, 5 5

be made in one piece with the supportingplates 13, but without the projecting pieces for preventing the foot slipping.

D is the pedal bar or pin, constructed as usual, except that the ball-race is formed on it at a distance from the ends to correspond with ball-cases C.

With the construction as above described, the length of the rat-trap bar between the supporting-plates being less than usual, the

of the latter, with edge bearings for the foot,

substantially as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

AUGUSTINE CAMPBELL DAVISON.
