To aZZ whom 2'2. may concern:

Be it known that I, ORON OVERTON, a citizen of the United States, residing at Mobile, in the county of Mobile and State of Alabama, have invented a new and useful Pedal for Motor-Cycles, &c., of which the following is a specification.

The invention relates to improvements in pedals for motor cycles, bicycles, etc.

The object of the present invention is to improve the construction of pedals, and to provide a simple, strong and durable pedal of inexpensive construction not liable to get out of order, and in which the pedal pin may be readily replaced in case of breakage of the same.

A further object of the invention is to provide a pedal of this character, adapted to dispense with anti-friction balls and similar anti-friction devices, and equipped with a bearing including inner and outer sleeves and means for preventing a separation of the same should the pedal pin become broken, so that the bearing faces of the inner and outer sleeves will not become filled with dirt and grit through an accident of that character.

WVith these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawing, and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawing :Figure l is a longitudinal sectional view of a pedal, constructed in accordance with this invention. Fig. 2 is a transverse sectional view on the line 22 of Fig. 1. Fig. 3 is a similar view on the line 38 of Fig. 1. Fig. l is a detail sectional view on the line H of Fig. 1.

Like numerals of reference designate corresponding parts in all the figures of the drawing.

In the accompanying drawing in which is illustrated the preferred embodiment of the invention, 1 designates a pedal pin consisting of a plain pin having threaded inner and outer ends 2 and 3. The inner threaded end 2 engages a threaded opening 4 of a crank 5, and the outer threaded end 3 receives a nut 65, which retains an inner sleeve 7 on the pedal pin. The inner sleeve 7 has a smooth interior, and its inner end fits against the crank 5 and its outer end is engaged by the nut 65. While a pedal pin having threaded terminals is illustrated in the accompanying drawing, any other form of pedal pin or a common bolt or similar fastening device of the proper size may be substituted for the pedal pin to repair damage in case of break age.

The inner sleeve 7 which is relatively fixed, receives an outer sleeve 8, mounted for rotation on the inner sleeve and maintained in spaced relation with the crank 5 by the means hereinafter described. The outer sleeve 8, which is provided with exteriorly threaded inner and outer ends 9 and 10, carries inner and outer pedal frames 11 and 12, which are rigidly secured to the outer sleeve at the inner end thereof by means of nuts 13 and 14: and to the outer end of the sleeve 8 by nuts 15 and 16.

The inner and outer pedal frames are each constructed of a single piece of plate steel, or other suitable material. Each of the frames is formed by two operations, the material being first cut to form a blank and the latter being then stamped or otherwise bent into rectangular form. The inner and outer rectangular pedal frames are fitted together at their ends, and are provided with registering openings 17 and 18 through which the threaded terminals of the outer sleeve 8 extend. The inner and outer frames are preferably provided at the openings with enlargements, which are located at spaced points intermediate of the ends of the strip of material forming each frame, the intermediate and end portions of the strip being narrower than the enlargements, which are preferably circular. The sides of the inner and outer frames are spaced apart through out the length of the pedal to provide spaces in which pedal rubbers 19 are secured by tubular rivets 20, or other suitable fastening devices, piercing the spaced sides of the inner and outer frames and the pedal rubbers at a plurality of points and securely fastening the said parts together. The inner and outer pedal frames are reversely arranged, the terminals of the inner frame being arranged at one side of the pedal while the terminals of the outer frame are located at the opposite side of the pedal, so that the joint or space of each :lrame is spanned by the intermediate solid portion oi the other trame.

lvo claim is made in this application to the particular construction of the pedal frame, l mounted on the crank, of an inner sleeve arranged on the pedal pin in a relatively hilt-3d which is claimed in a companion application, liled Apr. l0, 1912, Serial l lo. ($259,842.

The nuts 1-5, i l, 15 and to are preferably of hexagonal term, and the outer nut ll) is ror retaining the inner and outer sleeves against relative longitudinal movement.

in a device of the class described, the combination with a crank, and a pedal pin position, a relatively rotary outer slee e arranged on the inner sleeve and having a provided with an extension ll, arranged in by the outer sleeve, a nut mounted on the spaced relation with the nut (5 of the pedal pin and provided with an interior annular groove 2L, adapted to regheter with an exterior annular roove i-ilhlormed in the outer portion of the inner sleeve at a point beyond the outer sleeve. 'lhe extension Bl is ar ranged to rotate clear of the outer end of the inner sleeve, and a ci cular split contractile ranged in the interior an aura extension or the nu a ll 'lhe spring 24!: is of less diameter than the outer walls of the interior groove of the nut, and in assembling the parts, it is adapted to be expanded in placing the outer sleeve 8 and the nut is on the inner sleeve, and when the grooves 2:2 and are brought into register, the spring 2d contracts within the or the in ner sleeve and rrictionally engages the same. The groove 55-5 or the inner sleeve is designed in practice to be or" a depth somewhere between a third and a hall or the diameter or the material or the spring, which projects outwardly into the interior annular groove 22 sulliciently to retain the outer sleeve 8 on the inner sleeve. This will prevent the two parts from becoming; separated should the pedal pin brealr, and there will be no liability of the bearing faces of the two sleeves becoming filled with sand, dirt or other grit should the pedal be broken Tlhe retaining sprii'ig maintains the outer sleeve and the nut 16 in proper spaced relation with the cranlr and the nut c, that the relative rotary movement of the parts will not operate to unscrew the nuts. The err tension of the outer nut rotates freely over the circular spring, which through its resiliency, maintains itsc freely seated in the groove of the inner sleeve The nut (3 at the outer end of the pedal pin is or greater diameter than the inner sleeve and projects beyond the outer face of the same, and it forms a fastening means for positively confining the outer sleeve on the inner sleeve.

lVhat is claimed is 1. ln a device oi? the class described, the combination with a crank, and a pedal pin mounted on the crank, or an. inner sleeve arranged on the pedal pin in a relatively fixed positimi, a relatively rotary outer sleeve, a pedal frame carried by the outer sleeve, a nut mounted on the outer sleeve and provided with an extension, and means concealed within the extension and engaging' with the same and with the inner sleeve threaded outer end, a pedal frame carried threaded end of the outer sleeve and engaging the pedal frame and provided with an extension, and retaining means arranged interiorly elf the extension out the nut and coacting with the inner sleeve for holding the inner and outer sleeves against relative lon gitudinal movement.
