DRIVING MECHANISM FOR CYCLES.
SPECIFICATION forming part of Letters Patent No. 769,594, dated September 6, 1904,
Application filed March 31, 1903. Serial No. 150,488. (No modulo To all whom, it nmy concern.-
Be it known that I, CHARLES Enwam) DoULn,a subject of the King of Great Britain, residing at Spa Lane Mills, Spa Lane, Derby, England, have invented certain new and useful Improvements in Driving Mechanism for Cycles, of which the following is a specification.
The object of this invention is to construct an appliance for ordinary or motor cycles afiixable to the pedal-axle or to the chainwheel or to form part thereof that the riders feet may be made to assume their proper and natural positioni. 0., side by side so that they can be rested properly and not as at present with free-wheel cycles at a distance apart and in an unnatural position. purpose of my invention I will describe same as forming part of the chain wheel; but it must be understood that it can be equally well applied to the pedal-axle as a separate appliance.
My invention will be clearly understood from the following description, aided by the accompanying drawings, in which Figure l is a sectional elevation of my appliance with the cranks and mechanism in position for driving the chain-wheel. Fig. 2 is a similar view with the cranks and mechanism in the position they occupy when the riders feetare side by side. Fig. 3 is a side sectional elevation of Fig. 1. Fig. 4: is an elevation of the appliance with a portion of each crank broken away.
I arrange on or to the chain-wheel A for movement relatively thereto a ring B, having two inwardly-projecting flanges B, these having a thickened or closed portion 0 at one point with a chamber D. Between these flanges B, I pivot a tumbler E, this being controlled at one end by a spring F, the other end being shaped for engagement with one side of a bar G, connecting the two side plates H, one of which constitutes a sprocket-wheel. Said plates are suitably rigidly connected together and have a movement outside the ring l3 and flanges B. The bar G is in proximity to one end of the closed portion (1 of the two flanges B. On the other side of the bar G and within the chamber D, behind the thickened or closed portion C, is situate a segment 1, controlled by a spring J, the outer end of the segment I being shaped to engage the bar G, and said tumbler projects beyond the end of the thickened portion C and, in conjunction with the pivoted tumbler E and the end C of the thickened portion C, forms a lock for the bar G and positions the crank K with the chain-wheel A, the bar acting upon the thickened portion C to drive the machine.
The pedal-axle L and the thickened portion 0 between the flanges 13 are connected by a coiled spring M, and when it is required to place the feet together, such as when coasting, the rider presses one pedal .K backward, For the as in back-pedaling, and in so doing winds up the coiled spring M and forces the angled face N of the spring-controlled tumbler E against the bar (,r, whereby such tumbler is moved until it goes beyond the nose P of the segment I, when the segment I will be sprung into contact with the nose Q of the pivoted tumbler E to be locked in the adjusted position, the coiled spring M being further wound up by the travel of the pedal and crank K down to its lowermost position, as shown in Fig. 2, the bar (1? resting against a stop 0. The feet are new side by side and the machine running free, and when it is necessary to again propel the machine the rider takes off the pressure of his foot and allows the coiled spring M to return the lowered pedal, and in so doing the bar (1 acts against the segment I and forces it back free from the pivoted tumbler E, when the tumbler E will be forced into contact with the bar G by its spring F and relock the same for the pedaling motion.
The thickened portion may be dispensed with and the spring J and segment I be held in place by other means, and the stop 0 may be a rivet or bar connected to the flange B. hen the appliance is separate from the chainwheel, the plates B are secured to the pedalaxle direct.
\V hat I claim, and desire to secure by Letters Patent, is
1. The combination of two plates suitably united, and a connecting-bar between said plates, a ring mounted for turning movement between the plates, having a face adapted to bear against said bar, a spring-actuatedsegment, carried by the ring, to normally bear against said bar, a spring-controlled tumbler bearing normally against the bar, the latter, on the backward movement of said plates, serving to cause the shifting of the working end of the tumbler outward to engage the outer side of the working portion of said seg,
ment, a crank connected with said ring, a crank-shaft extending freely through said plates and provided with a second crank,means to limit the backward movement of the plates, and automatic means to return the plates to their original position.
2. The combination of two plates suitably united, and a connecting-bar between said plates, a *ing mounted for turning movement between the plates, having a face adapted to bear against said bar, a spring-actuated segment, carried by the ring, to normally bear against the bar, a spring-controlled tumbler bearing normally against the bar, the latter, on the backward movement of said plates, serving to cause the shifting of the working end of the tumbler outward to engage the outer side of the working portion of said segment, a crank connected with said ring, a crank-shaft extending freely through said plates and provided with a second crank, means to limit the backward movement of the plates, and a coiled springcircumscribed by said ring, one end of the spring being connected to the ring and the other end to the plates.
3. The combination of two plates suitably united, and a connecting-bar between said plates, a ring between the plates and arranged for turning movement relatively thereto, having a face adapted to bear against said bar, a spring-actuated segment to normally bear against said bar and carried by the ring, a spring-controlled tumbler supported by the ring and bearing normally against said bar, the latter, on the working movement of said plate, serving to cause the shifting of the working end of the tumbler outward to engage the outer side of the working portion of said segment, a crank connected with the ring, a crank-shaft extending freely through the plates and provided with a second crank, and a coiled spring within the ring, attached at one end to said ring and at the other to one of the plates.
4. The combination of two plates suitably united, and a connecting-bar between said plates, a ring having inwardly extending flanges, closed at one end, the closed portion having a chamber, a segment fitted within the chamber, a spring in the latter to bear against one end of the segment, the working end of the latter being adapted normally to engage said bar, a spring-controlled tumbler carried by'the ring, a crank connected with said ring, a crank-shaft extending freely through said plates and provided with a second crank having a beveled face to normally engage said bar, whereby, on the backward movement of the ring, the tumbler will be moved outward to engage the outer side of the working portion of the segment, a stop to limit backward movement of the ring, and means for automatically returning the ring to a primary position when the same is released.
In testimony whereof I have hereunto 'set my hand in presence of two subscribing witnesses.
CHARLES EDWARD DOULD.
