2 which receive the rear axle of the machine, the object of the elongated slot being to admit of adjustment of the disks for tightening and loosening the lacing. Nuts 24 24 on the ends of the axle are turned to hold the disks in place when they are adjusted to regulate the tension of the lacing. By this means a single operation is sufficient to tighten the entire lacing on a side of the machine, whereas heretofore it has generally been the custom to tighten each lead of the lacing separately, and even then it was impossible to tighten it very much, because the lacing had hitherto generally been connected with the mud-guard.

It is evident that slight changes might be made in the form and arrangement of the several parts described without departing from the spirit and scope of my invention. Hence I do not wish to limit myself to the exact construction herein set forth; but,

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is—

1. In a bicycle, the combination with a frame, and bearings, of a two-part pedal-shaft, the ends of which are secured together between the bearings and a sprocket-wheel interposed and secured between these adjacent ends of the shaft.

2. In a bicycle, the combination with a dip-frame for ladies’ wheels composed of two rods or tubes spread apart to receive the rear wheel of the machine and also at the bottom of the dip, of a mud-guard secured in the space formed at the bottom of the dip,

3. In a bicycle, the combination with a dip-frame for ladies’ wheels composed of two rods or tubes secured together at the forward end and spread apart at the rear to receive the rear wheel of the machine between them and also spread apart at the bottom of the dip, of two mud-guards, one secured in the space formed between the two rods or tubes at the bottom of the dip and the other in the space between the rods or tubes above the rear wheel.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
