VELOClPEDE.

SPECIFICATION forming part of Letters Patent No. 449,220, dated March 31, 1891.

Application filed May 6.1890. Serial No. 350,807. (No model.)

To all whom it 'Htc/,y 'conccrnf Be it known that I, THoMAs B. J EFFERY, a citizen of the United States, residing at Chicago, county of Cook, and State of Illinois, have invented certain new and useful Imlfirovements in Velocipede Dress Guards, Which are fully set forth in the following specification, reference being had to the accompanying drawings, forming'a part thereof.

In the drawings, Figure 1 is a side elevation of a drive-Wheel of a Safetybcyele With the adjacent portion of the frame and driving-gear and having devices Which constitute 'my improved dress-guard applied thereto.

Fig. 2 is a section at the line 2 2 through the mud-guard-supporting fork and mud-guard and lateral dress-guard. Fig. 3 is a section at the line 3 3 through the fork, showing the means of supporting the chain dress-guard. Fig. -t is a detail plan of a portion of a jointed frame containing the pivot of the two parts.

This invention relates to improvements in the dress-guard Which is designed to protect the dress of the rider from the mud carried by the drive-Wheel, and also toimprovemeuts in the guard which covers the drive-chain, and is designed to prevent the entanglement of the dress of the rider therewith. The firstmentioned guard has heretofore `g'enerally been made either of \vire-cloth or rods secured to the mud-guard or fork or chainguard or other essential parts of the framework, orin some instances to special parts added permanently to the frame-Work as means of securin g such \vire-cloth. The present invention is designed to provide a guard made of Wire-cloth or similar material, Which shall be complete Within itself independently of its fastening to the machine, and adapted to be removably secured, so that when the machine is used by a man, who has no need for the dress-guard, he can remove the same Withw out mutilating or practically unconstruotinr it. It comprises, therefore, two independent guardsA A, each made of a piece of Wirecloth bound by a rigid metal frame B, Which, as illustrated, is of :rod bent in the proper shape and having` the several \vires of the Wire-cloth fastened at their ends, Which constitute the margin of the cloth, permanently to such frame Wire or rod. The entire guard thus constructed is Secured to the fork C, being the fork Which is primarily intended to uphold the mud-guard D, by means of staplebolts or hooked bolts E-tl1atis,bo1ts having a hook E' at one end adapted to hook around the frame-rod B, While the other end orstem of the bolt pass'es through a hole in the fork C and is drawn tight, its hook E' being clamped ont-o the frame-rod and the latter drawn firmly against the inner side of the fork by means of the nuts E2 applied on the outer ends of the holts.

The other portion of the dress-guard--to wit, that Which gnards the dress from the chain-is represented by F. This chain dressguard is Secured at one endby a lug extending from it up to one of the bolts E, Which serves to fasten the dress-guard A in place on the fork C. The guard F extends from this point of support along` over the chain and around the sprocket-Wheel G to the lower side thereof, Where it. terminates, so far as the portion Which covers the chain is concerned; but it has the extension F' in the form of a rod bent in a vertical plane outside of the plane of the sprocket-Wheel-that is, substantially in the plane of the outer edge of the chain-guard F-extending around the remainder of the sprocket-Wheel not shielded by the curved portion of the guard F and fastened 'at its upper end to said guard. This extension F', in addition to supplementing the guard F as a means for keeping the dress of the rider off the Wheel, serves as a means of affording a second support for the guard F. It is made rigid at both ends With the guard F, and Where it passes by the fork C' a post H, rigidly fastened to said fork, juts out horizontally and has an eye at its outer end through Which the rod F' passes, and at Which said rod is rigidly Secured to the post, thus forming the second support for the entire guard F F', and holding it rigidly in place Without the necessity of securin` it to any other portion of the frame than the two forks or two portions of the fork, for they are made integral-to Wit, C and C'. This or any equivalent mode of sec'uring the chain dress-guard in such manner that it is supported upon the parts Which may be called the frame of the Wheel driven hy the TOO chain, said frame, as herein shown, consisting of the forks mentioned, is of especial importance inmachines in Which the frame of the driving-Wheel is pivotally Connected to the remainder of the frame (represented in the drawings by the frame-arm H) bya horizontal pivot perinitting` said two parts of the frame to move Vertically independently of each other, because such movement of the frame, (represented by the arms H',) if the dress-guard F Were connected to that part of the frame, would throw it out of proper relation to the ohain and either prevent it from suitably guarding; the chain or throw it onto the latter as the frame H moved relatively to the frame of the drive-Wheel, and it is in order to adapt such chain dress-guard to such machines that I have devised the above-described mode for supporting` it Wholly upon the frame of the Wheel driven by the chain.

I claim 1. In a velocipede having the frame of the driving-Wheel pivotally Connected to the remainder of the frame at a horizontal pivot,

whereby said two parts may have vertical movement independently of each other, in combination With the drive-wheel frame and the drive-wheel journaled therein, the crankshaft and the sprocket-Wheels on said crankshaft and drive-wheel shaft, respectively, the chain which communicates power between them, and the chain dress-guard F, overhanging said chain supported by connection solely With the drive-wheel frame, substantially as set forth.

2. In a \'elocipede, in combination With a drive-Wheel, the crank-shaft, and the forkv Which connects said shaft to the drive-wheel tending` partly around the driving' sprocketwheel and having` the extension F', 'consisting of a rod rigid With said dress-guard above and below said sprocket-Wheel, and a post extending from said fork at the side of the driving sprocket-wheel toward the drive-wheel axle and rig'idly connected to said extension F', \vhereby said fork supports the chain dress-guard, substantially as set forth.

3. In a velocipede, in combination With the fork Which extends from the crank-shaft to the drive-wheel shaft and the fork Which up holds the mud-guard, the sprocket-wheels on said shafts, respectively, and the chain Which communicates power between them, the chain dress-guard F, overhanging said chain and extending` half-way around the driving sprocket-Wheel and Secured at one end to the fork 'Which upholds the mud-g'uard and at the other end having the extension F', consisting of a rod rigid with said chain-Wheel guard and extending outside of the vertical plane of the driving sprocket-wheel around the portion of said Wheel not covered by the guard F, and the post H, jutting horizontally from the fo'rk and securd to said extension F', suhstantially as set forth.

4-. In a velocipede, in combina'tion With the forks C and O', the removable dress-guards A B and the bolts which secure them to the fork O, and the chain dress-guard F, having,r its upper end Secured to the fork O by one of the bolts Which fastens the dress-guard A B to said fork, substantially as set forth.

In testimony whereof I have hereunto set my hand, in the presence of two Witnesses, at Chicago, Illinois, this 1st day of May, 1890.

TI-IOS. B. JEFFERY.
