F. DOUGLAS. BIGYGLB PEDAL.
VNo. 469,295. Patented Feb. 23. 1892.
UNITED STATES PATENT OFFICE.
FRANK DOUGLAS, OF CHICAGO, ILLINOIS.
BICYCLE-PEDAL.
SPECIFICATION forming part of Letters Patent o. 469,295, dated February 23, 1892.
Application led August 31, 1891.
1 .To aZZAwQ/om t may concern:
Be it known that I, FRANK DOUGLAS, a citizen of the United States, residing' at Chicago, Illinois, have invented certain new and useful Improvements in Bicycle-Pedals, of which the following is a specification.
In the drawings, Figure 1 is a plan vieu1 of a longitudinal section of the pedal, taken through the shaft-bearing and rubber pedalpieces. Fig. 2 is a transverse section taken in the line 2 of Fig. l, looking in the direction of the arrow; and Fig. 3 is an enlarged sectional view of one of the ball-bearin g cups, showing the arrangement of the various parts.
In making my improvement in bicyclepedals I make the ball-bearing cup A of a single hardened piece of metal of the proper size and shape to receive the ball-bearings and provide it with a hole through its central portion. I make what I term a pedal-plate B, preferably struckout of steel-plate, so as to surround the ball-bearing cup and project over the outer edge of the same by a flange b. The ball-bearing cup is also preferably provided with a shoulder a, against which the inner edge of the plate rests. The ball-bear ing cups and the pedal-plates, when adjusted in position, are held together bya center tube H, which surrounds thel pedal-pin and which at its ends fits into the central holes in the ball-bearing cups and by the pins I, preferably square, which are screw-th readed at their ends and held in place by nuts t' on the outside of the pedal-plates. The edges or flanges b of the pedal-platesin projecting over the outer rim or edge of the ball-bearing cup A leave a little space between, in which I insert a Washer or protector O, made of cloth, felt, or other suitable material. This protectingwasher, when the ball-bearing cup and the pedal-plate are held in their position for use, is held firmly clamped between them. It serves as a protector to prevent dust, dirt, sand, or other injurious material from entering the ball-bearing. In making thc rubber Serial No. 404,238. (No model!) t-he ball of the foot of the rider in operation.
By making the ball-bearing cup and the pedal-plate of separate pieces adapted to t each other, as above described, I am enabled when one of the pieces becomes broken or injured to take it out and replace it with another without loss of the part remaining uninjured. `By providing a protector or washer at the end of the ball-bearing I prevent the ball-bearing from being injured by dirt or sand getting in, and by making the pedalrubbers more flexible at their inner sides I am able to secure a more easy and comfortable fit for the foot.
Vhat I regard as new, and desire to secure by Letters Patent, is-
l. In a bicycle-pedal, the combination of a ball-bearing cup and a pedal-plate provided with a flange extending outward and downward over the rim of the ball-bearing cup, substantially as described;
2. In a bicycle-pedal, the combination of a ball-bearing cup, a pedal-plate provided with a ange extending over the rim ofl the ballbearing cup, and a protector arranged between the flange and the rim, substantially as described.
3. In a bicycle-pedal, a rubber pedal-piece having its inner corners more fieXible or r yielding than its outer corners, substantially Witnesses:
