GEORGE L. MORRIS AND \VILLIAM T. -WILSON, OF LONDON, ENGLAND.

VELOCIPEDE.

SPECIFICATION forming part of Letters Patent No. 460,242, dated September 29, 1891.

Application filed May 23, 1891 Serial No. 393,809- (No model.) Patented in England September 9, 1889, No. 14,205, and

October 30, 1889, No. 17,215.

To all. whom, it may concern:

Be it known that We, GEORGE L. MORRIS and WILLIAM T. W ILSON, both subjects of the Queen of Great Britain, residing in the city of London, England, have invented certain new and useful. Improvements inVelocipedes, (for parts of which we have been granted patents in Great Britain, Nos. 14,205 and 17,215, and dated, respectively, the 9th. of September, 1889, and the th of October, 1889,) of which the following is a specification.

Our invention relates to that class of velocipedes having two equal or approximately equal sized wheels placed one in front of the other, the front one being used for steering and the rear one for driving, such machines being technically known as Safety bicycles, and its objects are, first, to provide a strong and rigid frame; secondly, to provideasimple and easy method of adjusting the drivingchain; thirdly, to facilitate theadjustment of the ball-bearings wherever applied; fourthly, to facilitate the attachment of the drivingchain wheel and the cranks to the pedal-crank axle, so that they may readily and easily be attached to or removed from the said axle, and, fifthly, to provide a means of attaching the pedal-pin to the crank, whereby the width of the tread may be materially reduced. lVe attain these objects in the manner illustrated in the accompanying drawings, in

which- Figure 1, Sheet No. 1, is a view in side elevation of a Safety bicycle embodying our improvements. Fig. 2, Sheet No. 1, is a perspective view in side elevation, on an enlarged scale, of the improved main frame. Fig. 3, Sheet No. 1, is a view in broken side elevation, on an enlarged scale, of the chain adjustment; and Fig. 4, Sheet No. 1, is a view in plan of the adj listing-bolt thereof. Fig. 5, Sheet No. 2, is aview in sectional elevation of a pedal-crank-axle bracket audits fittings, showing the improved method of adjusting the ball-bearin g and the improved method of attaching the cranks and the driving-chain wheel to the pedal-crank axle and the pedalpinto the crank. Fig. 6, Sheet No. 2, is a broken view in end elevation of the pedal-crank and axle with the washer and key removed, showing the keyway in the end of the axle and the ends of the bosses of the chain-wheel and crank. Fig. 7 is a broken view in end elevation, showing the method of attaching the pedal-pin to the crank. Fig. 8, Sheet No. 2, is a view in end elevation of the adjustable clip of the ball-bearing; and Fig. 9, SheetNo.

2, is a broken view in side elevation showing the application of the improved adjustment to a ball-bearing head. Figs. 10 and 11. are 6: broken views in end and side elevation of a modification of our improved method of attaching the cranks and chain-wheels to the pedaLcrank axle; and Fig. 12, Sheet No. 2, is

a broken View showing afurther modification of this part of our invention.

Throughout the several views similar parts are marked with like letters and figures of reference.

Referring to Figs. 1 and 2 of the accom- 7o panying drawings, the main frameA consists of eight essential parts, which are designated by numbers. 1 and 2 are forks, the prongs of which are joined together and slotted to form smallforks a to receive the axle B of the driving-wheel. The crowns of these forks are connected by a segmental tube 3. From the junction of the fork 2 and the segmental tube 3 a tube 4 runs forward and upward and is joined to the lower end of the socket 5, forming part of the steering head or joint. From the junction of the fork 1 and the segmental tube 3 a tube 6 runs forward and is joined to the top of the socket 5. From the junction of the fork 1 and the segmental tube 3 springs a short vertical tube 7, adapted to receive the stock of the seat-pillar, and across the angle formed by the tube 7 and the tube 6 a diagonal stay 8 is fixed. The bracket for carrying the bearings for the go pedal-crank axle is located at the junction of the fork 2 and the tube 4. A frame constructed on these lines may be made of tube of exceeding light gage, as its members are so arranged as to give the greatest rigidity 5 and strength to the whole structure.

Referring to Figs. 3 and 4, Sheet No. 1, of the accompanying drawings, in the small forks formed on the ends of the combined prongs of the forks 1 and 2 of the frame A IOO are cut or formed slots a, adapted to receive the ends of the axle 13, carrying the drivingwheel. On each end of the axle B is placed a Washer 0, having a screwed shank a set off to lie within the slot h. On this screwed shank is threaded a nut D, having a collar or rim 01 formed on it, adapting it to engage with slots or recesses 60 formed in the prongs of the fork a. The nut D may be formed with a square or hexagon head to enable it to be turned with a spanner, or it may be made with wings, forming a butterfly-nut, or the head may be simply milled to enable it be turned by hand. To adjust the tension of the driving-chain,the lock-nuts b b on the ends of the axle B are slackened and the adjusting-nuts D D rotated equally, thus imparting travel to the screwed shanks c c of the washers G O, and so altering the position of the axle B. After the necessary adjustment has been effected, the lock-nuts Z) Z? are tightened and the axle and washers locked tightly to the frame A.

Referring to Figs. 5, 8, and 9 of the accompanying drawings, we form on the outside of the adjustable cone E of a ball-bearing a split sleeve E, having lugs or ears 6 6, through one of which a screw 6 passes and is threaded into the other. Round the sleeve E at its point of attachment to the cone E and for i about half its circumference we cut or form allyused to lock the cone after adjustment.

Referring to Figs. 5, 6, 10, and 11 of the accompanying drawings, the crank F is fixed to the pedal-crank a'xle G by means of a key H, adapted to fit in a transverse keyway or sloth, cut or formed across the end of the axle and the boss of the crank. To keep the key H in position, a screw'g is threaded into the end of the axle and may either bear indirectly on the key H, through a washer H, as shown by Fig. 5, or directly, as shown by Fig. 11. The key H and keyway h may be either made with parallel sides, as shown by Figs. 5

and 6, or slightly tapered, as shown by Figs. 10 and 11. The washer H may be made in one piecewith the key H, as shown by Fig. 12. e fix the end of the pedal-pin J to the free end of the crank F by a key H, in the same manner that the crank is fixed to the pedal-crank axle, as shown by Figs. 5 and 7.

When it is desired to make the drivingchain wheel K easily detachable, it is formed with an elongated boss or sleeve it, over which the crank F tits, and both are then fixed to the axle G and to each other by the key H, as hereinbefore described, as shown by Fig. 5 of the accompanying drawings. Fig. 12 shows a modification of this arrangement, in which the abutting faces of the bosses of the chain wheel K and crank F are halved together and kept interlocked by the key H, which fixes the crank to the axle, as hereinbefore described.

We wish it to be particularly understood that we do not limit ourselves to the exact details of construction hereinbefore set forth and illustrated by the accompanying draw ings, but hold ourselves at liberty to make such changes and alterations as fairly fall within the spirit and scope of our invention.

WVe are aware that it is not new to make the main frame of a Safety bicycle of a diamond pattern nor to adjust the driving-chainv by moving the axle of the driving-wheel in slots in the main frame, nor to make the cranks and chain-wheel detachable from the pedal-crank axle, and we do not claim these broadly; but

hat we do claim as our invention, and desire to secure by Letters Patent. is-
