SPECIFICATION-Tw ning To all whom it may concern:

Be it known that we, CLAUDE H. OANDLER and JAMES WHITE'HEAD, of Detroit, in the county of Wayne and State of Michigan, have invented new and useful Improvementsin Tricycles; and we dohereby declare that the following is a full,-clcar, and exact description thereof, reference being had to the accompany lng drawings, which form a-part of this specig fication.

The nature of this invention relates to cer- 'tain new and useful improvements in the construction of that class of road-wagons ordinarily denominated tricycles. V

Theinvention consists in the peculiar construct-ion and application of quadruple pawls actuated by suitable treadles or levers and ar- 7 ranged to engage with a suitable ratchet-wheel upon the shaft, and so adapted that a forward or backward motion can be imparted to the vehicle at the will'of the operator, and in the peculiar construction, arrangement, and various combinations of the partspall as more fully hereinafter set forth;

Figure 1 is a perspective view of our improved tricycle, and Fig. 2 is a diagram show-. ing the-pawls reversed so as to produce a con l'rlllllOllS rearward IIIOVGIIlGllt.

In the accompanying drawings, A represents a suitableframe, mountedupon the axle B, which carries the traction-wheels G and are secured rigidly thereto, the said axle having proper hearings in the frame A. At the front the same plane.

Iare connected by suitable rods, J, to the ,treadle-levers K, the rear ends-of which are properly and pivotally secured to the frame A. L is a hand-lever, the lower end of which is rigidly secured to the rock-shaft H, the upper end coming within easy reach of the operator. M M represent two vibrating arms, one end of each of which is pivotally secured to the lever The outer ends ofthese arms art of Letters Patent 110,260,840, dated July 11, 1882. 5 Application filed May 24,1ss2.'. 1vo model.)

L, while the opposite ends are similarly secured to the outer ends of the vibrating framesN N, the inner ends of each of which are properly sleeved upon the shaft B, and between these inner ends of the frames N N a starratchet, O, is rigidly secured, by keying or other wise, upon the shaft B. Properly secured in each of the frames N N are the double pawls]? P, between the outer ends of each-of which is secured the proper spring, a, for the purpose of compelling an engagement between the pawls and the ratchet, as hereinafter set forth.

'; R represents a lever within easy reach from the seat F, and is connected by meansofthe bar S and the link T, the ends of which are jpivotally secured to the links U U, the inner ends of which are rigidly secured to short rock-shafts V V, properly journaled in the frames. N N, respectively, and each of these rock-shafts is provided with a cam, W

In practice, when it is desired to drive the device'forward the lever'lt is elevated, as shown in Fig.1, which, through the connections herein described, acts upon the cams W so as to allow the front dog of the upper pair and the rear dog of the lower pair to engage with the star-wheel, while they also prevent any engagement of the oppositepawls or dogs. By the operating the treadle-levers K K or the lever L, or both, a continuous forward rotary movement is communicated to the shaft 'B, which causes the vehicle to move forward,

its direction being determined by the guidewheelD, as may be desired by the operator. When a rearward or backing movementis desired the lever B is depressed, which causes the pawls or dogs to assume the positions shown in Fig. 2, and which are directly the reverse of those above described for imparting a forward movement. The operating of the treadle-levers will now cause the device to move backward.

By this construction and arrangement of parts it will be seen that we provide a means for impartinga forward or backward movementot' the device through the medium of quadruple pawls, operating upon the same shaft, and actuated by treadles andlevers common to both movements.

If desired, the axle may be constructed in two sections, so that the wheels can move independently of each other.

IOO

A slot, 11, in the hand-lever L allows of an adjustability of the links or vibrating arms M M upon said lever, by means of which its throw may be lengthened or shortened, as desired.

What we claim as our invention is- 1. In atricycle, the combination, with the shaft H, the arms I I, the rods J J, the treadles K K, and the lever L, having a slot, at, of the rods M M, the pivoted frames N N, the double pawls P P, the ratchet O, and the axle B, substantially as and for the purpose specifled.

2. In a tricyle, the combination, with the axleB andtheratchetO thereon, of the pivoted frames N N, the double pawls' P 1 and mechanism, substantially as described, for alternately throwing opposite members of the pawls P P into and out of engagement with the ratchet O, substantiall; as described.

3. In a tricycle, the combination of the following elements for the purpose of reversing the motion of the driving-axle, to wit: lever 1t, pitinan S, links T U U, rock-shafts V V, pawl-carriers, and cams, the parts being construc'ted, arranged, and operating substantially as and for the purposes described.
