SPECIFICATION forming part of Letters Patent No. 346,667, dated August 3, 1886.
Application tiled May 2l, 18H6. Serial No. 202,8S1. (No model.)
struction and combination of devices, that will be more fully set forth hereinafter, and particularly pointed out in the claims.
In the drawings, Figure 1 is a side elevation of my invention,with the near wheel removed.
Fig. 2 is partly an elevation and partly a vertical sectional view of the same. Fig. 3 is a top plan view, partly in section. Fig. 4 is a rear elevation. Fig. 5 is a detail perspective view of one of the bearings for the drivingshaft. Fig. 6 is a vertical section of one of the bearings for the rear axle. Fig. 7 is an elevation of a modified form of my invention, with the near wheel removed. Fig. -8 shows an auxiliary seat attached to backbone.
A represents a frame, which is composed of parallel side arms, B, connected at their front ends by a curved arm, C, and provided with a forwardly-projecting shank or arm, D. The arms B are connected together by transverse bars E and F, which are arranged respectively near the rear and front ends of the frame. rlhe central portion of the frame is bent downwardly from a horizontal line, as shown in Fig. l. The rear ends of the arms B are provided with laterally-projecting bearing-boxes G, in which are arranged a series of anti-friction rollers, g, the projecting spindles at the ends of thesaid rollers being journaled in rings g', which are placed in the ends of. the bearing-boxes.
H represents a transverse shaft, which is journaled in the bearings G, and extends outwardly beyond the outer sides of the frame A. To one end of the said shaft is rigidly attached a large wheel, I, and to the other end of the said shaft is loosely attached a similar wheel.
K represents a sprocket-wheel, which is loose on the shaft H, and is located near one of the arms B, and L represents a smaller o sprocket-wheel, which is also loose on the shaft, and is located near the opposite arm B. A slidingclntch, M, is placed on the shaft H, and is adapted to move back and forth thereon, so as to engage with either of the wheels K and L, or to be moved to the central portion of the shaft between the said wheels and out of engagement with either of them.
To the lower ends of the bars B are attached bearing-blocks N, which are provided with depending plates a, having longitudinal horizontal slots a. Bolts at pass transversely through the said slots and through the sides of the bars B, and thereby permit the boxes N to be moved forwardly or rearward] yin the frame A, and to be adjusted thereon at any desired point within the limit of the slot u.
O represents thedriving-shaft, whichis j ouri naledy in the boxes N, the said boxes being provided with anti-friction rollers similar to the rollers g of the bearings G.. To `the center of the shaft O is attached a friction-wheel, P, and to the ends of the said shaft are attached crank-arms O. The said arms are provided near their outer ends with slots O2, and extend in opposite directions from the shaft O. Pedals O are attached to the outer ends of the crank-arms by means of transverse bolts, which extend through the-slots O2 and are secured therein at any desired adjustment by means of clamping-nuts, which are screwed onto the inner ends of the said bolts. On one side of the friction-wheel P, and in a line with the small sprocket-wheel L, is a large sprocket-wheel, It, which is rigidly attached to the shaft O, and on the opposite side of the friction-wheel, and in aline with the large sprocket-wheel K, is a small sprocketwheel, S, which is also rigidly attached to the shaft O.
T represents a brake, which is fulcrumed on the cross-bar F and is provided with a rear- Ward-extending curved arm, T', having its inner side covered with rubber or leather or other suitable material and adapted to bear against the periphery of the friction-wheel. An arm, T, projects forwardly from the brake and is provided at its outer end with a suitable pedal.
U represents the backbone of the tricycle, which is provided at its lower rear end with the vertical forks U', which are attached to IOO the rear ends of the bars B. From one of the said bars depends a step, V. In the front ends of the frame A and of the backbone U is journaled a guiding-rod` XV, which is provided at its lower end with the forks XV', be-
tween which is journaled the small steeringwheel X, which runs in front of the large wheels I. The upper end of the guiding-rod is reduced, thereby forming a shoulder, w, and upon the said upper end of the rod is placed acoiled extensile spring, w', the lower end of which bears upon the shoulder w and the upper end of which bears under the front end of the backbone. To the upper end of the guiding-rod XV is attached the usual steering-arms, Y.
Z represents the seat, which is supported upon a curved flat spring, Z', the said spring bearing upon the backbone, and is provided with a clip, Z2, having a set-screw, which elnbraces the backbone and permits the seat to be adjusted forwardly or rearwardly thereupon to suit the convenience of the rider.
a represents a lever-arm, which is fulcrumed to the backbone between the forks thereof, and extends downwardly and engages the feathered sliding clutch on the shaft H.- The upper end of the lever a works in a transverse loop or keeper, b, which is secured to the backbone and is provided on its rear side with a series of openings, b. The lever-arm has a stud, b2, which projects from its rear side and is adapted to engage either of the series of openings b and thus lock the said arm thereto. It will be readily understood from this description that when the upper end of the leverarm a is moved to the right the sliding clutch will be moved to the left on the shaft H, so as to lock the large sprocket-wheel K to the said shaft, and that by moving the upper end of the leverarm to the left the sliding clutch will be moved to the-right, thereby disengaging the large wheel K .and locking the small wheel L to the shaft H. XVhen the lever-arm a is in a vertical position, the sliding clutch is arranged between t-he wheels K and L and out of engagement with both 'of them, and therefore the said wheels are both loose on the shaft H. An endless sprocket-chain, d, connects the small wheel L with the large wheel B, and a similar endless chain, e, connects the large wheelK and the small wheel S. By thus providing the drivingshaft with the large and small wheels, which are connected, respectively,to the small and large wheels of the main shaft of the tricycle, and by providing means for throwing either of the wheels out of gear with the main shaft of the tricycle, it will be readily understood that the machine may be caused to run either very rapidly or not so fast, as may be desired, by moving the lever a., and without altering the speed of the driving-shaft O. The tricycle may be thus propelled very rapidly on level ground and caused to run slowly up an incline, and thus avoid excessive fatigue on the part of the rider.
By providing the guiding-rod XV with the spring w, to support the front end of the backbone, an easy and pleasant motion is imparted to the tricycle, and the latter is thus prevented from jarring and jolting the rider.
f represents a lamp-holder, which is composed of abent arm, f', that is attached to the guiding-rod XV by means of a set screw, h, and bears upon the front end of the pivotal part of the frame A, thus preventing the latter from rising on the driving-rod.
k represents an arm,which engages the guiding-rod W, and the front end of said arm is provided with a series of openingsJc. Through one of these openings passes abolt, kiwhieh connects the said arm with the bent arm f of the lamp-holder. By means of this construction it will be understood that the front arln of the lamp-holder may be adjusted forwardly or rearwardly with relation to the guiding-rod XV, so as to throw the light from the lamp either to the ground directly in front of the machine, or at a considerable distance ahead.
Z represents a seat or platform, which is attached to the rear lower side of the backbone U by means of a clip, l', and the said seat or platform is provided with depending supporting-arms Z2,whieh are attached to the forks U of the backbone. The said seat or platform enables the machine to carry two persons.
In Fig. 7 I illustrate a modified form of my invention, in which the frame A is provided with a rearward extension, m,which carries a driving-shaft, o, having a gear-wheel, p, connected to one of the wheels on the shaft H by means of an endless belt, and the shaft ois also provided'at its ends with oppositely-extending crank-arms provided with the pivoted pedals. From the rear end of the extension m rises a vertical standard, s, which carries a vertical]y--adjustable seat, t, supported upon a spring, t. When the tricycle is provided with this apparatus, it is adapted to be used ,i
double, and each person riding the tricycle can assist in 4propelling it.
Having thus described in my invention, I clai1nl. The combination, in a tricycle, of the frame A, the backbone attached thereto, the steering-rod W, carrying the front wheel, and pivoted to the front ends of the frame A and the backbone, and the spring 'w' on the upper end of thesteering-rod and bearing under the front end of the backbone, for the purpose set forth, substantially as described.
