WILLIAM DIEBEL, OF PHILADELPHIA, PENNSYLVANIA.

PEDAL.

SPECIFICATION forming· pari of Letters Patent No. 644,818, dated March 6,1900.

Application filed October 6,1898. Serial Ho. 692,814, (Ho model.)

To all whom it may concern:

Be it known that I, William Diebel, a citizen of the United States of America, and a resident of Philadelphia, county of Phila5 delphia, State of Pennsylvania, have invented certain new and useful Improvements in Pedals, of which the following is a specification.

My invention relates particularly to bicycle-pedals, and more especially to that class io in which the pedal-blade is suspended from the crank-pin instead of being centrally mounted thereon.

My present improvements consist in the novel construction of the pedal-blade and of 15 its connection to the crank-pin bearing, and they are fully described in connection with the accompanying drawings and specifically pointed out in the claims.

Figure 1 is a side elevation, partly in sec20 tion, of a complete pedal embodying my improvements. Fig. 2 is a rear end view o'f the same, a portion of the rear disk being cut away to show the interior of the mounting. Fig. 3 is a plan view of the pedal-blade. · Fig. 25 4 is a partial bottom view indicating a modified connection of the pedal-blade to the crankpin bearing.

In the preferred construction shown in the drawings I employ the single bearing-ball 30 mounting shown and claimed in Patent No.

582,183, issued to me May 11,1897, and in the specific form shown in Patent No. 598,197, issued to me February 1,1898, and I do not therefore desire to claim the same herein.

In my present invention the bearing ring or casing B is mounted upon the pivot-pin A, ivhich is rigidly secured to the free end of the crank-shaft, said ring, as shown, being provided with relatively-adjustable disks C and 40 O', forming conical outer bearing-surfaces for the single line of balls D, and said balls being supported upon the inner disk E, rigidly fixed to said pin or shaft A and being spaced by means of the spacing-ring F, all substan45 tially as shown in said Patent No. 598,197, and the adjustment of the bearing-disks and the locking of the same in proper position are secured by means of the slotted rim c on the screw-disk C and the catch o', arranged to en50 gage it in a manner similar to that described in said Patent No. 582,183.

The bearing-ring B is formed with a circu lar exterior rib &amp;, which is formed at intervals with a series of openings which leave intervening solid portions for the purposes here- 55 inafter described. These openings preferably consist of recesses V, formed by cutting away the periphery of the rib at intervals.

The blade G is adapted to be formed of sheet metal cut and pressed into the shape 60 shown in suitable dies. The inner end g is shown formed with a series of ears g', which when the sides of the punched plate are bent up into shape, as shown, are adapted to slide into engagement with the recesses V of the 65 bearing-ring B. The side edges g² g², intermediate of the ends, are similarly upturned and preferably serrated, as shown, to provide a suitable foot-bearing. The outer end g³ is spherically formed and has an upward exten- 70 sion gd above the level of the side edges g² g²to serve as a stop for the foot. An opening g³ in the dished portion affords free exit to water or dirt and reduces the weight without practically affecting the strength, which is 75 very considerable owing to the dished form shown. A toe-clip and additional foot-piece may be attached, if desired.

In attaching the pedal-blade to the bearingring B the ears g' on the former are adapted 80 to enter the peripheral recesses b' Of the ring, as stated, until the end edge g^s of the blade is in contact with the rib &amp; of the ring, in which position they are rigidly clamped, as shown, by setting down over the recessed 85 edges g⁷ of the ears the portion of rib metal extending above the thickness of the latter. A slightly-modified means of attachment is indicated in Fig. 4, in which the ears g^s of the pedal-blade extend through openings b² in the 90 bearing-ring and the projecting ends g³ are bent or clenched to securely connect the parts.
