SPECIFICATION forming part of Letters Patent No. 374,084, dated November 29, 1887.

Application filed July 19, 1887. Serial No. 244,702. (No model.)

To all whom may concern:

Y Be 1t known that I, EMIL J. F. QUIEIN, a

Tioga Centre, in the county of Tioga and State of New York, have invented certain new and useful Improvements in Combined Car Brake and Starter; and I do hereby declare that the following is afull, clear, and exact description of theinvcntion,whichwillenableothersskilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, andiirwhich- Figure 1 is a. top plan view of the bottom frame of a tram-car-provided with myimproved brake and starter. Fig. 2 is a bottom view of the same. Fig. 3 is a longitudinal vertical sectional View on line x x, Figs. 1 and Fig. 4 is a perspective view ofthe mechanism at one end of the car, showing the frame-work showing parts of -the wheels broken away.

Similar numerals of reference indicate cor responding parts in all the figures.

My invention has relation to that'class of car-starters used in tram-cars or street-cars in which the power of the team pulling on the draw-head in starting is con veyed to the wheels, turning them, thus rendering the starting easier than the 'dead straight pull upon the tion and combination of parts of sucha starter in which4 the brakes which serve to stop the revolutions of the wheels are mounted upon pivoted arms which will bring the brake-shoes olutions, and at the same time when operated from the draw-bars will carry the brake-shoes upward and forward, starting the wheels, as hereinafter more fully described and claimed. In the accompanying drawings, the numerals 1 indicate the sidesills of the bottom frame or platform of the car, and the ends of these sills are connected by the end pieces, 2, and by cross-pieces 3 and 4, forming supports for the dash and the end platforms of the car. The sills are provided with suitable brackets` and boxes, 5, for the ends of the axles 6 of the wheels 7, all of which parts are of the usual construction.

The draw-heads 8 may be of any suitable construction, and are secured to or form parts ofthe draw-bars 9, which slide longitudinally iu bearings 10 -upon the under sides of the cross-pieces and end pieces, and these drawbars have coiled springs 11 wrapped around them and bearing against the outer crosspieces and against pins or bolts 12, inserted through the draw-bars at the outsides of the bearings in the inner cross-pieces, the springs serving to return the draw-bars into their normal inwardly-drawn positions.

The upper side of the forward portion of each draw-bar is provided with a notch, 13, having a forwardly-facing shoulder, and dogs 14 are pivoted uponvthe inner sides of the end pieces and may engage the said notches when allowed to drop downward, the said dogs having upwardly-projecting arms 15, which may be engaged by slides 16, sliding in vertical slots or ways 17 in the dash-boards of the platforms, holding the 'dogs raised out of engagement with the notches.

A rock-shaft, 18, is journaled in suitable transverse bearings, 19, under the inner crossy piece at each end of the car, and this shaft is provided at its middle with a downwardlyprojecting arm, 20, to the end of which a bar, 21, is pivoted, having its forward orouter arm pivoted t'o the draw-head, and the ends of the shaft have downwardly-projecting arms 22 secured to them.

Sleeves or collars 23 are journaled upon the axles immediately inside of the wheels, bearing with their ends against the wheels and against suitable stops, 21, upon the axles, and arms 25 project radiating from the ends of these collars, having rods 26 pivoted to their outer ends and to the ends of the arms upon the ends of the roel-shaft, the said arms projecting normally upward. The forward or outer sides of the inner ends of these arms at the collars are provided with eccentricallyprojecting cams 27, which bear against pins or studs 28, projecting inward from the short arms of levers 29; pivoted and sliding with' longitudinal slots 30 upon the axles between the collars and the wheels, the outer ends of the long arms of these levers having the brakeshoes 3l secured upon them and projecting normally toward the middle of the car.

IOO

Chains 32 are secured to the sills and to the ends of the long arms ofthe levers, preventing the arms and shoes from falling to the ground or rail. rlhe inner sides of the long arms of the levers are provided with inwardly-proj ccting perforated ears or lugs 33, in which slide rods 34, having shoes 35 upon their inner ends bearing against the collars, and having coiled springs 36 bearing against the shoes and against the inner ears, forcing the said shoes against the collars.

Levers 37 are fulcrunied to rock in a horizontal plane upon brackets or arms 3S, projecting inward from the inner sides of the inner cross-pieces, and the inner ends of these levers have downwardly-projeeting lips 39, with which they bear against the inner ends of the draw-bars,while brake-rods 40 or chains are attached to the outer ends of the longer arms of the levers and pass to the brake-shafts 41 at the ends of the ears, having chains 42 at the ends which wind upon the brake-shafts, the said brakeshafts having suitable handles, 43, and ratchet-wheels 44,engaged by the usual pawls, 45.

Then the car is normally ruiming, the dogs at the ends ot' the platforms are supported in their raised positions by the slides holding the upwardly-projecting arms allowing the drawbars to be drawn freely out, the dog at the end having the team attached to it,howevcr,being let down when the car has been started, so that the dog may engage the notch of the drawbar when the pull has ceased and the spring of the draw-bar has drawn it in. When it now is desired to stop the car, the brake-shaft is turned in the usual manner, winding the chain and drawing the outer end of the lever at the oppositeend inward, forcing the end having the lip against the inner end of the draw-bar at that end, forcing the drawbar out. This will cause the draw-bar to draw outward upon the bar pivoted to it, drawing the arm of the rock-shaft outward and tilting the arms at the ends of the shaft outward, which will again in their turn tilt the arms of the collars outward, causing their cams to draw the levers inward and bringing the brake-shoes to bear against the wheels, the arms gradually drawing the arms so far outward that they will carry the levers and brake-shoes with them and reverse the motion of the wheels, effeetually stopping the ear.

Vhen it now is desired to again start the car, the dog at the end at which the team is is raised, which maybe done by a kick of the foot by the driver, whereupon the brake is released and the team started. This will cause the team to draw out the drawbar at that end, rocking the shaft and bringing the brakeshoes at that end in contact with the wheels and tilting the levers upward and forward, causing them to carry the wheels with them, so that the ear will be effeetually started, the wheels revolving freely under the brake-shoes when the latter are raised to the highest position. XVhen, now, the car has been started sufficiently to run freely, the spring of the draw-bar will draw it in, and the springs upon the rods having the shoes bearing against the collars will force the brake-shoes from contact with the wheels, sliding the levers outward with the slots, so that the shoes will again occupy their normal positions and be ready for again operating upon the wheels.

It will be seen that in stopping the ear the wheels which at that time are the rear wheels will be revolved in the opposite direction to which they revolve when traveling forward, so that the car will be most effeetually stopped, and so that the tendency of the wheels to revolve in one direction will force the brakeshoes so much harder against them, and it will also be seen that the team will exert a much more advantageous pull upon the wheels starting their revolutions than if simply pulling against the car in a straight line. It will also be seen that if the team makes false starts or jumps, as is often lthe ease, every start will bring the car forward, bringing the car against the team and preventing its stalling or balking, the device doing away with the dead-pull, which is liable to make ear-horses balky, as they do not feel any effect of their starts and simply pull against a dead object, and curing theirbalkiness by forcing the car forward upon them when they have jumped forward and fall back. In this manner the device will save the live stoel; by enabling it to exert thc greatest power with the slightest exertion, and will at the same time prevent the forming of bad habits of the stock.

Having thus described my invention, I elai n1 and desire to secure by Letters 'Patent of the United States- 1. In a car-startcr, the combination of a sleeve journaled upon the axle ofthe wheels and provided with a radiating arni having a cam projecting forward at its inner end, a lever, 29, sliding with a longitudinal slot upon the axle between the end o1' theslceve and the wheel and having a stud, 2S, upon its inner short arm bearing against the cani 27, and having a shoe, 31, at its outer end for clamping the periphery of the wheel, and provided with a spring, 36, for sliding it outward upon the axle, and a sliding draw-bar, 9, suitably connected to the arm of thc sleeve, as and for the purpose shown and set forth.
