B. J. ANDERSON PEDAL CONSTRUCTION June 22, 1937.

Filed April 20, 1935 1 a1) W 1 a 4 7 a 7 Z 4 my/v HA Patented June 22, 1937 UNITED STATES PATENT OFFICE 11 Claims.

This invention. relates to an improvement in a velocipede pedal construction and has for one of its chief objects the economical construction of an article consisting of a few parts whic may be easily assembled.

Another important object of the pedal of this invention resides in the construction of the body itself which is preferably of extruded rubber composition having a plurality of longitudinal openings therein.

A still further important object of the invention resides in the fact that the central portion of each working surface is corrugated and that the walls of this portion of the body are of greater thickness than are the walls at either end.

Still another and further important object of the pedal here set forth resides in the means for preventing rotation of the body independent of the sides.

A further important object of this invention resides in the bushing means for securing the plates to the body.

An additional object of importance resides in the provision of means for preventing the plates from squeezing or otherwise distorting the resilient body of the pedal.

Additional objects of importance and advantage, some of which are hereinafter set forth, will be apparent from the disclosures made in the accompanying drawing and the following specification.

, -As shown in the drawing:

The reference numeral l0 indicates in. a general'way the body of the pedal of this invention which is substantiallyoval in cross section and is preferably constructed of a resilient rubber composition. The body ID is preferably extruded in long strips which may be cut into any length,

depending on the width of the pedal desired.

Penetrating the center of the body I0 is an aperture I2 which follows thelongitudinal axis of the strip. When out into pedal lengths this aperture is used for a bushing receiving opening.

Positioned on each side of and parallel to the aperture l2 are apertures l4 and [6. These apertures l4 and it serve the purpose of requiring less stock in the manufacture of the article, providing greater resiliency at the front and rear edge of the body, and also a securing means for keeping end plates in alignment. The aperture I6 is substantially triangular in section and the aperture I4 is semi-circular as the surfaces of both conform in contour to the adjacent outer surface of the body I0,'as is best shown in Figure 5. The portion of the body directly above and below the aperture I2 is comparatively thick, as is best shown in-Figure 5, to resist wear.

Positioned on each end of the body it is an apertured end plate l8 which has depressions 20, and 22, adapted to be inserted into the apertures I4 and I6, respectively. The aperture 24 is adapted to receive the end of a castellated bushmg.

Extending through the aperture l2is a bushing'26. each end ,of which is castellated as is clearly shown in Figure 9. This bushing is preferably stamped from sheet metal in flat form, as

i is best shown by the reference numeral 28, in Figure 10, and is then rolled into cylindrical formation. Each end of the bushing 26 protrudes from the body I0, and is adapted to receive an end plate which is secured in position by the portion 30, of the end plate l8 coming into contact with the portion 32 of the edge of the bushing, which prevents inward movement, and by crimping the portion 34 of the bushing against the outer surface of the plate l8, as is best shown in Figures 2 and 11, to prevent outward movement.

A crank shaft 36 adapted to receive the pedal has an upset 38 on opposed sides thereof and a restrictedend; portion. In mounting the pedal on the shaft 36 for use, a washer 4|] is slipped onto the shaft and against the upsets 38. The shaft is'then inserted through the bushing 26. Positioned on the restricted end of the shaft with said restricted portion passing therethrough is an apertured cap 42. The end of the shaft is then headed 44 to hold the pedal in operable position on the shaft.

It will be apparent from the foregoing that symmetrical and balanced pedal.

the pedal highly desirable for use with the new herein is provided a semi-solid enclosed pedal which may be quickly and economically manufactured and which may be secured to the crank shaft of a velocipede without the aid of nuts or bolts or special tools. It will be further apparent that bolts and nuts or their equivalents are not requiredin the assembly of the various parts.

Furthermore, because of the absence of rivets or bolts adjacent the ends of the plates, streamlining can be carried out and still maintain a This makes streamlined velocipedes.

I am aware that many changes may be made and numerous details of construction varied throughout a wide range withoutdeparting from the principles of this invention, and I, therefore, do'not purpose limiting the patent granted hereon otherwise than as necessitated by the prior art. w

I claim as my invention:
