UNITED STATES Enron- PATENT THEODOR SOETBEER, OF NEW YORK, Y.
CAR-STARTER.
No. 274,399, dated March 20, 1883.
Application filed January 9, 1883. (No model.)
i the city, county, and State of New York, have invented a new and Improved Car-Starter, of which the following is a full, clear, and exact description.
The object of this invention is to devise means, more especially intended for use on street-ears, whereby the force required to stop the carmay be stored up and used in starting the car. 7
Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.
Figure 1 is a plan view of the bottom of a street-car having my invention applied to one of the axles thereof. Fig. 2 is a detailed elevation of the axle and pinion, showing the starting and stopping racks in transverse section; and Fig. 3 is a plan view of the starting and stopping racks.
A represents the spring. B represents the pinion, placed loosely upon the square axle G. D represents the stopping'and E the starting rack, attached at their rear ends to one end of the spring A; and F F represent cams for shifting the pinion for stopping, locking, and starting the car. These cams are operated by the connecting-rods G G, attached-t0 them and to the cog-wheel H, which is adapted to be turned in either direction by the pinion J attached to the vertical brake-rod K, as will be understood from Fig. 1.
It is designed to provide both axles of the car with starting devices, and for this purpose 1 make the spring A s-shaped, so that both of its ends may be utilized, requiring but a single spring for both sets of starting devices; and I attach the spring A to the bottom L of the car by means of the staples a a.
The pinion B is made with the reduced portion 1), larger portion b,'and reduced plain portion 11*.
The stopping and starting racks are attached together at {their ends, as shown at f f, and are pivoted to the end of the spring A by the pivot g, and the starting-rack E has rack-teeth only for a short distance, as shown at h in Fig. 3, and passes over orabove the axle O and rests in contact (except as hereinafter described) with the larger portion 1) of the pinion B. The stopping-rack D has teeth nearly its whole length, as shown at 11/, passes under the axle (J, and is held up in contact (except as hereinafter described) with the reduced portion 11 of the pinion by the guide-staples d d. The starting-rack E also passes through these guide-staples, which serve to hold the racks firmly and securely in place.
The operation of the device is as follows.- When the car is in motion the pinion B will have been shoved along upon the axle G by the cam F, so that the reduced portion 12 of the pinion will stand to one side of the stoppingrack D, as shown in Fig. 1, and the spring A will have moved the racks D E forward until the teeth h of the starting-rack E will stand in front of the teeth of the larger portion 1) of the pinion, leaving the plain portion of the rack E resting nponthelarger portion 1) of the pinion. In this position it will be seen that the racks E D in no manner interfere with the free revolution of the axle O or the movement of the car'in either direction. When it is desired to stop the car the brake-rod K will be turned so as to cause the cam F to shove the pinion on the axle O to the position shown in Fig. 2, in which position the pinionwill stand to one side of the starting-rack and the teeth of the reduced portion b will engage the teeth of the stopping-rack D, and thus the forward movement of the car will cause the rack D (carrying the rack E with it) to he moved forcibly back against the spring A, causing it to be compressed and to act as a brake to the axle and car. The car having come to a full stop, the brake-rod K will be turned so as to cause the cam F to shove the pinion B to a position intermediate between the positions shown in Figs. 1 and 2, in which position the teeth of the reduced portion 3) will still engage the teeth of the rack D, and the teethof the larger portion 1) will engage the teeth hof the rack E, which will lock the springA in its compressed state and hold the car at rest. Now, to start the car the rod K will he turned still further to cause the cam F to shove the pinion B along on the axle C until the teeth of the reduced portion 1) disengage the teeth of the stopping-rack D, whereupon the force of the spring A will force the racks forward, and this force will be applied through the startingraclr E to the upper side of the pinion B, causing so that there will be no danger of the pinion coming to a dead stop against the teeth of either rack.
The object in making the pinion B with the reduced portion 1) and larger portion I) is so that the backward movement of the racks will not be too rapid, and so that the force of the spring A will be augmented in the starting of the car.
Havingthus described my invention, Iclaim as new and desire to secure by Letters Paten t 1. In a car-starter, the wheel H, adapted to be rotated by any suitable means, the rods G G, end pivoted to opposite sides of said wheel, and the pivoted cams F F, in combination with aslide-pinion, B, whereby said pinion will described.
2. In a car-starter, the loose shifting-pinion B, having the large spur portion b, the small spur portion b, and the plain portion 12 and the end connected bars, D E, having respectively the opposite long and short racks h h, in combination with axle 0, whereby the actuatingspring may be made to operate in either or in be alternately moved in opposite directions, as
neither direction according to the position of 3 5 the wheel, as described.
3. The racks D E, pivoted to the spring A, in combination with the pinion B, cams F F, rods G G, wheels H and J, and vertical shaft K, as and for the purposes set forth.
4. The rack D, having the teeth h, extending its whole length or nearlyits wholelength, and the rack E, having the teeth h, extending only a portion of its length, in combination with the pinionB, adapted to slide upon the axle O, as and for the purposes set forth.
