DARIUS FULLER, OF CHICAGO, ILLINOIS.
CAR-STARTER.
SPECIFICATION forming part of Letters Patent No.483,349, dated September 27, 1892.
Application filed May 17, 1392. Serial No. 433,311. (No model.)
To all whom zit may concern:
Beit known that I, DARIUs FULLER, 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 Car-Starters, which are fully set forth inthe following specification, reference being had to the accompanying drawings, forming a part hereof, and in which-- Figure l shows a vertical longitudinal section of a car with my improved car-starting mechanism applied. Fig. 2 shows a transverse vertical section in front of one of the caraxles. Fig. 3 shows a plan view of a car as seen on its under side with my said improved car-starter attached thereto. Fig. 4 shows a transversevertioal section of a car, taken in front of the mechanism attached to the center of the car-bottom.
Like letters refer to like parts. y
The object of my invention is to provide a car-starter for either horse or cable cars, or like vehicles which require frequent starting, of simple, efficient, and practical form, and which may be made to reverse its action on the car when the car-front is reversed, and in order to attain said desirable novel features I construct my said new device in substantially the following manner, namely: Under the car-Hoor and about midway between its axles and parallel to them I attach a drum a', having a friction end or surface c at one end and forming a part thereof, which is herein shown increased to a large diameter and forming a flange. There is a groove a? at the opposite end of said drum, in which play the ends of a forked lever c, fulcrnmed at c', which forms a shiftinggear for said drum. Said drum is loose on its axle and is reciprocated longitudinally thereon by said lever c, which may be operated in any suitable manner-for instance, as herein shown, by a reciprocating bar f, which moves longitudinally 1n suitable guides and is provided with a slot j" in it at such an angle to its direction and length of motion as to give to the upper or outer end of said lever e, which plays in said slot, sufficient motion to said drum for its operation on a friction-head l), opposite to the fiange or and on the same shaft with it. Said head is provided with a pulley c, which forms a part thereof, or there may be two such pulleys,
and the power from both oar-axles utilized, or, in other words, itis but a single pulley adapted to receive two belts, and preferably they should be chain belts. Opposite said pulley c is a small pulley c on the car-axle, from which a belt d runs on the pulley c. (A second and like beltand pulley areindicated in broken lines in Fig. 3.) Through said or like mechanism the friction-head b rotates while the car moves, and it will rotate the drum a Whenever the friction-headset and b are brought into contact. To said drum is attached a rope or chain g and to the end of the rope aspring h, whereof the outer end is secured to the carbottom. The rotation of the drumis resisted by the spring h, and thus, through said connected mechanism, the car will be stopped. To the drum a another rope g is fastened, which unwinds from as the rope g is Wound upon said drum. The outer end of the rope g is Wound around the pulley and fastened thereto, and to said pulley is attached and wound thereon a sufcient distance a second rope g2, whereof the outer end is attached to a second spring h', which is longer and much weaker than the spring 7a and which acts in the contrary direction thereto--that is, when the spring h expands it contracts, and conversely.
When each car end is to be the front end of the car alternately, I provide ratchet-Wheels 7c It with pawls jj', pivoted on opposite sides of the pulley t', which engage with said ratchet- Wheels. To alternately release and engage said pawls, I provide some suitable mechanism-as, for instance, that herein shown, which answers the purpose. Said mechanism consists of pinsm and m onthe ratchets near their points, of which the outer ends play on cones n and n. Said cones turn with the caraXle by means of a spline and slide longitudinally thereon. Each of said cones has a circumferentially-grooved outer end,into which project spurs of a connecting and shiftingbar o, which is actuated bya lever o. A roller m2 may run on the ends of said pins to reduce the friction of them on the cones. Said shifting mechanism is now shown set for one direction of motion of the car. By means of said arrangement either one of said pawls may be raised from its ratchet-Wheel and the opposite pawl engaged with its ratchet `-at pleasure.
IOO
`Sfr-thus starts the car.
Said cones, pins, and shifting-gear, tbc., are not required if the same end is always the .front end of the car. In that case only one ratchet-wheel and pavvl connect with the pulley t', and in either case the pawl that is down clicks idly on the ratchet-Wheel While the car is going forward, because the pulley t is held from turningby the ropes g and g2 until the spring h has been woundupand thecarstoppedafterwhic 1o when the friction-heads a and b are separated, the pawl gives the car-axle and its wheels the motion of the pulley i", and thus starts the car. Said ropes g g2 are wound'on opposite sides of the drum or pulley t', the position of which must be reversed when the opposite end of the car from the one in use is made the front end thereof. Vhen the same end of the car always remains the front end, then only one ratchet-wheel and pawl are required and the zo shifting-gear and all shifting of parts necessarily required with it will not be required.
The operation of my said device is, when the car is moving in the direction indicated by the arrow and as shown by the full-line 2 5 parts of the drawings, as follows, namely:
When it is desired to stop the car, the friction-heads a and b are brought into contact through the lever p and intermediate mechanism.. This causes the drum c to revolve 3o against the constantly-increasing and powerful resistance of the spring 7i, until the car is stopped, and thus through the motion of the drum a wind the rope g upon it and at the same time also unwind from it the rope or chain g,which had at iirst been wound upon it, and wind the same upon the drum 'L'. The action of the drum t' is due to the spring h', which is constantly in tension or extended position and only strong enough to wind said 4o rope upon the drum t'. The direction of motion of the drum i is such as to cause the pawl to click on the ratchet-wheel. Vhen the car has ceased to move, the spring h is in tension and the spring h in diminished or lower tension. Vhen the friction-heads a b are separated, the force of the spring h revolves the drum a, and thus causes the rope g to wind upon it from the drum i, which through such motion turns said drum t' with its axle, and
It is .also important to note that the proportion of the pulleys and drums is such as will secure the greatest effect-namely, the small pulley c revolves the large pulley c, which winds up the spring h on a small drum, and that when the spring h transmits its stored-up power it acts on the small druma, which turns the large pulley fi. Vhcn the motion of the car is reversed, the drum a will revolve in the opposite direc- 6o tion, and consequently wind the ropes gandg on the'opposite side of the drum. This will thenrequire that the rope g be Wound in the opposite direction on the drum t', as must then also be the rope g2, wound on the opposite side of said pulley t', and the spring h Vmust be placed from the position in which it is shown into that indicated for it by the broken outlines, after which the cones must be shifted, so as to raise the pawl which was engaged into the idle position and the opposite pawl thereto put into the active position. Then all parts will again operate for the end desired. Itmust also be observed that said pawls point and act with their ratchet-wheels in opposite directions and that said ratchetwheels are keyed to the car-axle.
Vhat I claim isp l. The combination, with alternately-acting, of different tension, and in the same direction acting springs, whereof one connects to two drums, loose upon their shafts,whereof one of said drums revolves in either and the other in only one direction without and in the other direction with its shaft, of aconnection opposite to that already made on one of saidl drums to one of said springs, connecting mechanism from the drum free to revolve in either direction, and the car-axles, and clutch mechanism to said drum, substantially as specified.
