PEDAL FOR VELOCIPEDES, BICYCLES, 8w.

Specification of Letters Patent.

, Patented Jan. 22, 191%.

Application filed. May 16, 1917. Serial No. 168,940.

To all whom it may concern:

Be it known that I, RICHARD Gr. LEDIG, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented'a new and useful Pedal for Velocip'edes, Bicycles, &c., of Which the following is a specification.

My invention consists in providing the pedal proper of the pedal of a velocipede, bicycle, etc., with ballbearings on the bolt on which said pedal proper is supported and by which it is connected with the crank arm of the velocipede, bicycle, etc., in a firm and durable manner.

The invention is satisfactorily illustrated in the accompanying drawing, but the important instrumentalities thereof may be varied, and so-it is to be understood that the invention is not limited to the specific details shown and described, so long as they are within the spirit or scope of the claims.

Figure 1 represents a plan view ofa pedal embodying my invention.

Fig. 2 represents a longitudinal section on an enlarged scale on line 2-2 Fig. l.

Fig. 3 represents a side elevation of a detached member thereof.

Fig. 41 represents a partial side elevation of another detachedmember, and sections of adjacent portions. V

Fig. 5 represents an elevation of a bolt employed.

Figs. 6 and 7 represent elevations of detached members of the pedal proper of the device.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings z-- 1 designates a bolt, one end of which is provided with a head having on its inner side the conical portion 2 which is surrounded by the cup 3, between which latter'and the adjacent portion of the bolt 1 are interposed the balls 4:, said cup having on its inner side the reduced neck 5 which freely encircles the adjacent portion of the bolt 1, the conical surface 2 of the head of the bolt, and the shoulder 6 of the cup 3 and neck 5 serving to retain said balls 4 laterally in position in the ball race formed by the said members.

7 designates a barrel which freely encircles the main portion of the bolt, and 8 designate avcup which isformed with a reduced neck'9 which latter freely encircites the adjacent portion of the bolt 1, it being noticed as in Fig. 2 that the end portions of the barrel 7 are fitted tightly on the neck 9 and 5 of the respective cups.

1O designates the pedal proper of the device, the same consisting of a U-shaped plate composed of the side pieces 11 which extend parallel with the barrel 11 and front bend 12 joining said pieces 11. Connected with the latter are the cross plates 13 which have openings 1 1 centrally therein so as to fit over the necks 5 and 9 of the cup 4: and 8 respectively.

On the bolt opposite to the head 2 is the tubular plug 15 which has a conical inner end 16, the latter partly entering the cup 8 and forming with the same a ball race which receives the balls 17 which are adapted to roll on the adjacent portion of the bolt 1, it being noticed that the conical end of the plug and the shoulder 21 formed by the cup 8 and the reduced neck 9 thereof retain the balls 17 laterally in position.

On the outer terminal of the bolt is the threaded stub 18 to which the crank arm 19 of the velocipede is secured in any suitable manner. It will be noticed that the terminal portion of the bolt 1 passes through said stub 18 and has its end riveted on the adJaCeHt end of said stub as a head 20 which connecting said bolt with said plug and the other parts of the device, and preventing the bolt from displacement.

The plug 15 is properly spaced on the bolt by means of the engaging shoulders 22 and 28 respectively on said bolt and the bore of the plug, the effect of which is evident.

It will be noticed that the cups have ball bearings respectively on the conical surface 3 of the bolt 1, and on the conical end 16 of th plug 15, and so the barrel 7 has indirectly ball bearings on the bolt, rendering the pedal proper 10 of the pedal to rock with but little friction, and consequently with greatest freedom on the bolt.

The surface of the main body portion of the plug 15 is made polygonal as at 24, whereby it may be properly engaged by a wrench or other implement, so that the plug may be turned conveniently in screwing it into the proper part of the crank arm 19, or for removing it therefrom, and the terminal of said body adjacent to the threaded stub 18 has thereon the shoulder 25 against I overlaps the bore of said stub, thusfirmly which the sideof the contiguous portion of the arm 19 abuts, so as to form a tight said bolt at the o'uterterminal of the stub of the plug 15 is riveted or. headed on said terminal as at 20, and so the plug is fixed to the bolt, and the latter retained in its operative position, the device then being made up in its'entirety as a compact, firmly united, inexpensive, strong and durable structure.

Having thus described my invention what l claim asnew and desire to secure by Letters Patent, is

1. In a pedal for a bicycle or the like, a bolt-like member, a pedal proper rotatably mounted'thereon, a tubular plug having a stub, said bolt being passed through the bores of said stub and plug, the terminal portion of said bolt being secured on the outer end of said stub.

2. ln a pedal'for a bicycle or the like, a bolt-like member, a pedal proper rotatably mounted thereon, a tubular plug having a stub, said bolt being passed through the bores of'said stub and plug, the terminal portion of said bolt being secured on the outer end of said stub, and means on said bolt and plug serving to space the latter.

1 3. In a pedal for a bicycle or the like, a

V bolt-like member, a pedal proper rotatably mounted thereon, a tubular plug having a f stub, said bolt being passed through the bores of said stub and plug, the terminal portion of said bolt bein secured on the outer end of said stub, sald bolt having a shoulder and the plug having an interior shoulder cooperating therewith to space the plug to prevent cramping of balls'engaged by the inner end of the plug.

4.
