SPECIPICATION forming part of Letters Patent No. 342,620, dated May 25, 1886. Application filed February 4, 1886. Serial No. 190,827. (L o model.)

To (til whom it may concern;

Be it known that I, ALEXANDER W. Mo OLURE, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Velocipedes, of which the following is a specification. to wit:

This invention relates to velocipedes; and

it consists in certain peculiarities of the construction and arrangement of the same, substantially as will be hereinafter more fully set forth and claimed.

In order to enable others skilled in the artto which my invention pertains to make and use the same, I will now proceed to describe its construction and operation, referring to the accompanying drawings, in which Figure l is a plan view of my device; Fig. 2, a side elevation of the same; Fig. 3, a view of the clutch-drum with its face removed .Fig. 4, a detail view of the swiveled handle-bar; Fig. 5, a detail section of the steering-head. Fig. 6 is a bottom view of the pedal-lever and its band attachment. Fig. 7 is a detail view of the adjustable supporting-legs and their operating-lever.

The object I have in view is to provide a velocipede of simple and cheap construction, and of such peculiar form as will permit its being ridden by different riders of varying To this end I prefer to use wheels of small size, which I deem better for various reasons; but I may of course nse'any size of wheel desired.

The front wheel, a, is provided with the usual fork, rd, in which it is hung, and to which is hinged the backbone or connecting-frame, b, which connects the front and rear wheels, at a. This connecting-frame or backbone is, however, in this machine carried back entirely and only upon one side of the position occupied by the rider, as shown clearly in the drawings. This enables me to use a much lighter connection, as no weight is placed upon it, and it is entirely out of the way of the rider in mounting or dismounting, or while upon The rear wheel is mounted on a spindle or projecting arm, 12, secured .to the connecting-frame or backbone in any desired or suitable way, and upon this same spindle I mount a seat-support, consisting of a standard or standards, 0, which may rise on one or both sides of the wheel, in this case being shown on both sides. These standards are hollow, and in them are held adjustably by set-screws c extension-rods c", the upper ends of which are bent forward, and on these ends is secured thesaddle c", which may be adjusted back and forward to suit the rider in the manner usual with such articles, and not necessary to more fully detail at this point.

The backbone or connecting-frame is extended back, or an 6Xt6nSl0lIa1ll1 is secured toit, as at d, to the rear periphery of the wheel, where it is provided with a suitable cross-block or casting, d, to which the pedallevers are secured. These levers d are hinged or otherwise attached; but I have here shown them as provided at their rear ends with a spring section or leaf, d which is secured rigidly to the block d, and acts not only as a spring to lift the lever to its highest and normal position, but as a support and hinge, its flexibility serving to give as free play to the pedal as an ordinary pivot. It may be a separate piece, as herein represented, or it may be an integral portion of the lever-arm drawn down, and suitably tempered.

The levers are each represented as formed or provided with an arm, d, which projects upward either before or behind the clutchdrum, and.is connected with said drum by a flexible connection, (P, which is wound upon the drum (or on an auxiliary one secured to it or formed with it) as the lever is depressed and unwinds as the lever rises, thus serving to return the drum to its proper position after each stroke without the use of any returningspring on the clutch, as is usual.

Upon the hub of the wheel are suitable clutches, which are connected to the operating pedal-levers by straps or similar flexible connections, d, to form driving-bands, asin the drawings; and it will be particularly noticed that the weight and power applied to or carried by the machine is all supported from or upon the axle or spindle or the hub of the wheel, and little or no strain is thus brought upon the connectingframe, which is thus enabled to be made very light, as it is simply a connection to retain the two wheels in the desired relative position; The saddle is also supported upon this spindle, and connected by braces to the rear extension of the frame,

so that none of the weight is su pportcd directly by the frame.

It is evident that any desired form of clutch is readily applicable to the machine; but I prefer to use the clutch herein shown, which is substantially the same as secured to me by a former patent dated December 1, 1885, No. 331,518, the changes herein made being such details of construction as enables me to apply and operate it to better advantage than the precise form shown in that patent. It consists of a loose cylindrical drum, 6, upon the hub or axle, having within it a band, a, which surrounds and clasps the hub or axle, as in Fig. 3. This band I have shown made in two parts hinged together; but may, if desired, make it in one piece, this being a matter of preference with the maker. In any case the two ends of the clutch-band do not quite meet, but one end lies close upon the axle, and the other is extended at a tangent thereto, passing as closely past the opposite end of the band as may be, in order that it may have as large a frictional contact with the hub or axle as possible. This band is tightened or caused to grip by means of a small dog, e", which is at its outer end engaged by a lug or projection of the drum or case 6, and at its inner end formed with a heel, e, engaging the short end of the band, and a toe, e", engaging the extended end of the band, and it will'be seen that as the dog lies, as shown, between the band ends, as the drum is revolved the dog is rocked to press the short end of the clutchhand down on its work and at the same time draws the ends together and causes it to clutch firmly the surface to be driven. As soon as the forward action of the drum ceases the natural spring of the band expands it just suflicieut to release its grip and al ow the wheel to run free, while the drum is turned back to its normal position, which is done either by the action of a return-spring; (not herein shown,) and which is a common and well-known feature of reciprocal drivingclutches, or by the means hereinbefore described. The expansion and contraction of the clutch-band is so slight as to be almost imperceptible to the eye, and for this reason its action is almost instantaneous, and there is no unpleasant lost motion, as is often the case with ratchet-clutches, besides which it is perfectly noiseless. To insure the clutch band returning with its drum or case on the backward motion, I provide a spring. 0", which lies between a projection or shoulder on the band and a similar one on the case, and acts, as in Fig. 3, tokeep all the parts in exact position for proper and instant action. It will be evident that this spring holds'the dog in constant contact with the projection on the drum, and therefore 'the machine or its wheel cannot be moved backward, as this motion of the wheel acts at once to close the band and clutch the axle in the same way as would the forward motion of the clutch drum. It is, however, a great advantage to permit the backing of the wheel when desired, and to accomplish this I provide the clutchband with a projecting arm, 9, which I have represented as protruding through the shell of the drum, and it is evident that any pressure upon this arm in the same direction as the driving-power is applied will move the clutchband forward sufficiently to prevent pressure between the clutch-dog and drum, and the wheel may then be freely backed. This pressure may be applied by hand when desired; but I prefer to render the disengagement of the clutch automatic; and to this end'I have provided the operating pedal-levers with a spur orprojection, g, which, when thelever is lifted to its highest and normal position. will strike and move forward the clutch-arm g, a very slight movement being all that is required. The clutches are thus thrown out of gear automatieally whenever the levers are at their point of rest, and the machine is freely backed, yet is always ready for instant use and forward motion.

It will be understood that it does not matter to what part of the clutch-hand the arm is secured, and this arm may well bea continuation of the tangent extension of the band; but the movement of the band to accomplish the object sought must always be in the same direction as the application of power in driving. Neither do I desire to confine myself to cansing this disengagement of the clutch by means of the pedal-levers, as it is evident that a stop for this purpose and of suitable character may be attached upon any convenient point of the frame or spindle, and this in some instances will be done, depending somewhat upon the especial form of frame. levers, and other accessories which the judgment of the builder will dictate.

The flexible drivingbands are liable to stretch with use, and as in the general use of the machine it is better and in this case necessary to take up the slack and always return the levers and drums to the same point, I secure the driving'bands to the levers by means of screws 0. passing loosely through the lever,- and provided with nuts, o, to adjust them. These nuts are preferably formed angular, or with a projection, 0", to fit a corresponding socket in the levers, and thus prevent any accideutal turning of the nuts on the screws when in use.

While the steering-head of an ordinary bicycle is readily used on this machine, I desire to render the steering nearly automatic, or, in other words, to give the steering-wheel a tendency to automatically return to its proper position when deflected from that position; and for this purpose I terminate the front fork in a vertical spindle, h, (shown in dotted lines in Fig. 5,) at the baseof which is a supporting-plate, h, having a depression across its face, as at h", or, in other words, the upper face of this bearing-plate inclines from the sides toward a depressed line through the center of the same. The backbone or connecthandle-bar must, however, be wholly in a ing-frame is provided with a sleeve, 27, which surrounds the spindle h, and is on its lower end formed to correspond with the plate on which it rests, as seen in Fig. 5. The sleeve rests in the depression of the fork when the wheels are in a line, as is their normal position, and when the steering-wheel is turned to one side or the other, it will be seen that the sleeve rides upon the inclines or cams of the fork or plate, and, always having a tendency to slip down into place again, aids in returning the wheel to its normal position and retain it there. It will be evident at once that it does not matterwhether the depression of the plate radiates in a longitudinal, a transverse, or other direction, or if the parts are reversed and the elevation be placed on the plate and corresponding depressions in the sleeve, as the effect sought to be obtained is had in either case. To prevent the sleeve from jumping and rattling when passing over rough ground, I form its upper end with an elevation, h, also radiating or crossing the sleeve in any desired direction, and fixed upon the spindle.- Above this is a nut or disk, h, formed on its lower side with a similar elevation, the two elevations resting upon each other, as in Fig. 5. It will be evident from this that as the sleeve lies in position it is held down by the disk above it; but as it lifts in turning it freely follows the contour of the disk and is always in contact with it, being firmly held, but freely turned, as will be at once understood.

The steering-bar k is secured upon the standard or spindle h, and allowed to extend rearward as far as desired. At its rear end it is forked, and swiveled therein is-thetransverse handle-bar it. This construction enables the rider to move the steering-bar freely from side to side without the handle-bar interfering with the body, as would be the case if this bar were rigidly attached. This swiveled motion of the horizontal plane, as it must be rigidly held against any tendency to twist or move in a vertical direction.

Too much stress cannot be laid upon the connectingframe, which is passed entirely upon one side of the riders position, and [do not desire to confine myself to any particular shape to accomplish this, as the result is the same whether the frame be formed as herein shown or looped or bent around the rider, and brought back to a central position and forked to the rear wheel; but I do not deem such construction a desirable one, as it materially lengthens the machine, and is of no advantage.

In machines of this character, having two trailing-wheels, it is obvious that the equilibrium is preserved chiefly by the motion of the machine, and that it will not retain an upright position when not in motion. To obviate this, which is an especial objection in the use of the machine by ladies, I have formed the axle or spindle of the driving-wheel hollow, and passed loosely through it a rock-shaft, m, which is upon each end provided with an arm or rest, in, of sufficient length to rest upon the ground when desired. This rock-shaft is also provided with a crank-arm, m connected with the end of a lever, m,which is fulcrumed on the main frame, and provided with a spring, m, to return the parts to position after use. When the lever is moved, it allows the legs or supports to drop to the ground, where they brace and support the machine in proper position while the rider mounts or dismounts or stops to talk. \Vhen the machine moves forward, these legs simply drag, and are lifted at any time by the return action of the springactuated lever. I provide a catch, it, to hold thelever down when desired, and I secure upon thelever the brake-spoon n, which bears upon the rim of the wheel when depressed and checks the speed. As the braces or legs are required when the motion is checked or stopped, it is evident that it is a great convenience to operate them and the brake at the same time. A stopof any kind may be provided to prevent the too great swing of these logs or braces.
