Specification of Letters Patent.

Patented June 26, 1906.

Application filed June 17, 1905. Serial No. 265,776.

To (LZZ whom it may concern:

Be it known that I, RICHARD NEWMAN, a citizen of the United States, residing at Washington, in the District of Columbia, have invented certain new and useful Improvements in Mud-Guards; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to mud-guards.

One object of the invention is to provide an exceedingly simple, inexpensive, durable, and eflicient mud-guard for bicycles, automobiles, and the like.

Another object of the invention resides in the provision of a mud-guard particularly adapted for association with bicycles.

A still further object is to provide a peculiarly formed mud-guard embodying a peculiar connection for support upon a bicycleframe.

lVith these and other objects in view the present invention consists in the combination and arrangement of parts, as will be hereinafter more fully described, shown in the accompanying drawings, and more particularly pointed out in the appended claims, it being understood that changes in the form, proportion, size, and minor details may be made within the scope of the claims without departing from the spirit or sacrificing any of the advantages of the present invention.

In the drawings, Figure 1 is a side elevation illustrating the construction and arrangement of the front mud-guard. Fig. 2 is an elevation showing the construction and arrangement of the rear mud-guard. Fig. 3 is a section on line 3 3 of Fig. 1.

Referring now more particularly to the accompanying drawings, it will be seen that a portion of a bicycle is illustrated in order to disclose my peculiar form of mud-guard for the front wheel 1. The reference character 2 represents the upper bar of the bicycleframe, and 3 the front fork of the bicycle.

The mud-guard 4 for the front wheel is of peculiar formation, one end being reduced, as at 5, with the longitudinal edges of thereduced ortion 5 bent to form a concave surface 6 or engagement with the lower curved surface of the upper bar 2 of the frame. In other words, the bar 2 is usually circular in cross-section, presenting what might be termed a convex outer surface for fit in the correspondingly-formed or concave surface 6 of the reduced end 5 of the guard 4. In order to positively hold the reduced end 5 of the mud-guard in engagement with the bar 2 of the bicycle-frame, I employ a clamp 7, whose free ends are pierced by. a screw threaded bolt 8, with which isengaged a nut 9 for tightening the clamp and positively securing the reduced end 5 of the guard against displacement with respect to the frame of the bicycle.

The guard 4 at the base of its reduced portion 5 is directed downwardly, as at 10,with its side edges gradually diverging to awidth somewhat greater than the width of the reduced end 5, the downwardly directed widened portion 11 of the mud-guard 4 being curved with respect to the curvature of the front wheel until it reaches a plane slightly above the axle of the front wheel, when it is curved into a substantially horizontal plane, as at 12. The guard is then directed upwardly in neck form, as at 13, and then curved rearwardly, as at 14, and bent to form a concave surface 16, similar to the concave surface 6 of the reduced portion 5 at the forward end of the guard, whereby it may be secured to the frame-bar 2 by means of a clamp 17. This clamp 17 is of the same type of clamp as that indicated by the reference character 7 and is held tightly upon the frame-bar 2, with the reduced end 15 of the guard therebetween, by means of the bolt and nut 18 and 19, respectively. As has been stated, the opposite ends of the guard are reduced and concaved, and reference to the drawings will disclose that the broadened portion 11 of the guard between its reduced ends is also concaved, as indicated by the reference character 20. However, the concaved face of the guard between its ends is in a plane opposite to the plane of the-concaved surfaces of its ends.

It will thus be understood from the foregoing that the mud-guard described is not only of a eculiar form, but that it is composed of a single piece of sheet metal or other suitable material. It will also be understood that the guard is supported solely from the upper bar 2 of the bicycle-frame, obviating the necessity of arms or rongs usually em ployed and connected to t e axle of the front wheel for the su port of the guard.

In Figs. 6 and 7 of the drawings there is shown a peculiar form of guard 21, associated with the rear wheel 22 of a bicycle. It will IIO be seen that the forward end of the guard 21 is reduced, as at 23, and bent into hook form, as at 2 1, for engagement with the transverse brace 25 of the upright or rear fork arms 26 of the bicycle, a bolt 24 being passed through the hook to clamp it in place. The guard proper, 21, immediately in the rear of its reduced end 23, has its side edges diverging outwardly to form the guard proper of a width somewhat greater than the width of its forward reduced end 23. This widened portion is of concave-convex formation in crosssection and follows the curvature of the rear wheel 22 to a point substantially parallel with the horizontal plane of the axle 27 when it is directed outwardly and rearwardly, as indicated by the reference character 28. Now in order to support this rear guard 21 over the rear wheel I employ supporting members comprising each a pair of diverging arms 29 and 30, each arm of each pair being connected in any suitable manner to the side edges of the guard 21, with their ends flattened in the form of a washer 31, for engagement with the corresponding ends of the axle 27 between the ends 32 and the corresponding upright or fork-arms 26 of the bicycleframe.

By reason of my peculiar form. of mudguard the rider of the machine is protected from flying dirt or mud, the concavo-convex formation in crosssection of the guards preventing the flying of dirt and mud in lateral directions as well as perpendicular directions. Either form of mud-guard is very simple, and it is to be understood that the same are readily applicable to bicycles, automobiles, or other vehicles.

What is claimed is- 1. A mud-guard comprising a body portion concavo-conveX in cross-section and provided with reduced ends of concavo-convex formation in cross-section, the concavo-conveX faces of the ends of the guard being disposed opposite to the concavo-convex formation of the body portion.

2. The combination with a bicycle, of a mud-guard comprising a body portion curved transversely into a concavo-convex shape on a radius such that it will lie with its concaved face parallel with the transverse curvature of the bicycle-tire, said body portion having its end portions reversely bent into transversely concavo-convex shape and receiving a portion of the frame of the bicycle, said body portion being curved longitudinally and lying parallel to the periphery of the tire.

3. The combination with a bicycle including wheels and a frame, of a mud-guard having a body portion concavo-convex in crosssection, said body portion having an integral end portion of concavo-conveX formation in cross-section, said end portion being disposed with a portion of the frame in its concavity, and a fastening-clamp engaged with said end and the frame.

In testimony whereof I aflix my signature in presence of two witnesses.

. RICHARD NEWMAN.
