COMBINED CAR STARTER AND BRAKE.

SPECIFICATION forming part of Letters Patent No. 401,340, dated April 16, 1889. appresso ned January 12, 1389. seria it. 296,132. (No model.)

To @ZZ whom, t may concern.-

Be it known that I, SILAS I3. FYLER', of East Syracuse, county of Onondaga, in the State of New York, a citizen of the United States, have invented certain new and useful lmprovement-s in Combined Car Starters and Brakes, of which the following is a speciiication, reference being had to the accompanying drawings, in which- Figure l is a bottom plan ViewA showing the position of parts when acting as a brake; Fig. 2, a like view showing position of the parts subsequent to the starting of the car; and Fig. 3, a side elevation with two wheels removed, showing parts in saine posit-ion as illustrated in Fig. l.

Similar letters and figures of reference indicate corresponding parts throughout the severa-l vi ews.

The obj ect of this invention is the construction of a combined ear starter and brake that is adapted to propel a car forward a short distance from the power derived or stored up in the braking of same-that is, operated by the car-driver (or brakeman by the pressure or non-pressure of his foot or hand) upon a manipulating-rod, and which mechanism may readily be attached to the running-gear or bottom of a car or other road vehicle, and which is comparatively inexpensive of manufacture, and at the same time being of durable construction and reliable and etlicient to operate.

It consists of the several novel features of construction and operation hereinafter described, and which are specically enumerated in the several clauses of claim hereunto annexed.

It is constructed as follows: A A are the car-wheels, rigidly secured to the axles B B in any ordinary manner, said axles being journaled in any preferred bearings, although represented in the drawings, by way of illustration, as journaled in a double metallic carrying-frame, C, secured to the bottom D of the car. Longitudinally with and to one side of the center of the cars bottom l secure thereto and pendent therefrom the elongated carrying-rod E, having angular extremities or stops a a.

F is a horizontal rack-bar lyingbeneath the rod E and. suspended therefrom at its ends by means of supporting-bars terminating with vertical projections or arms li l), provided with apertures, through which passes the carrying-rod E, said apertures being of suiiicient dia-meter to permit of the free travel of the vertical arms or hangers b l) (and connected rack-bar) on the aforesaid rod.

c is a pin or stop inserted in the rod E at about the location shown, which holds in position a collar or buifer, d, and extending therefrom to the forward arm or hanger, l), of the rack-bar l encircle the aforesaid rod E with a strong, powerful, and heavy coiled spring', G, as shown, and being non-compressed.

The lower or rack face of the horizontal rack-bar F meshes in a pinion, H, mounted loosely on the axle B and terminating at one side in the serrated sleeve I, formed integral therewith, and at the opposite side of the aforesaid pinion I secure a coiled spring, e, upon the axle and held in position by a pin, f, whereby a yielding pressure is obtained against the aforenamed pinion.

J is a corresponding pinion, located near the opposite end of the axle B and keyed thereto, and terminating at the side adjacent to the pinion I-l in a serrated sleeve portion, K, the serrated edge of which engages with the serrations on the sleeve l of the loose pinion H, the two parts combined forming a ratchet-clutch, l..

L represents a shaft, journaled at one end in a bearing, lvl, attached to the bottom of the car and at its opposite end in the vertical eX- tremity of the angular operating-bar N, said bar being pivoted to the car by suitable means, or directly to a frame, O, thereof, as at g, and thence extending longitudinally forward and pivotally secured to a verticallydisposed manipulating-rod, O, passing through the car bottom or platform.

71, is a spring, one end being secured to the bottom of the car and the other to the operating-bar N.

Upon the shaft L, adjacent to the bar N, I secure a pinion, P, and at the opposite end a smaller pinion, Q, adapted to mesh in the rack-face of the rack-bar F. At either point, when the shaft L is journaled, the aperture IOO is sufliciently enlarged or elongated to permit of a certain degree of lateral movement of the aforesaid shaft. Y

lVIy device ,is operated as follows: The car being in motion and a stoppage thereof being desired, I depress and keep depressed (preferably by the pressure of my foot) the manipulating-rod O, causing the forward pivoted end of the operating-bar N to drop, thus throwing its vertical inner extremity with the shaft L and pinion P (and pinion Q) inward and upward, said pinion thus meshing in the pinion J on the forward axle, B, and impelling the rotation of the shaft L, with its smaller pinion, Q, which pinion, meshing with the rack-face of the rack-bar F, instantly propels the said bar rearwardly until the tight compression of the propulsion-spring G, by the inward movement of the rack-bar, in conjunction with the passage of the rack-face past the axis of the pinion Q, effectually brakes the forward. car-wheels, and tlius brings the car to a positive stop. y

During the aforedescribed operation the loose pinion H is rotated upon its axle by the rearward travel of the engaging rack-bar, the serrated sleeve K of the keyed pinion J rotating and slipping past the serrated edge of the JlIeeve I of the yieldingly-held loose pinion To start the car, I release my weight from the rod O, whereby, by means of the spring h, the forward elongated portion of the lever L iiies upward and the inner vertical portion thereof outward and forward, thus releasing the pinion P from engagement with the pinion J and the pinion Qfrom engagement with the rack-face of the rack-bar F, whereupon the coiled propulsion-spring G (the compression against it being now removed) immediately expands itself, propelling the rack-bar forward, the rack-face of which meshing in the pinion H causes that and its integral serrated sleeve I to rapidly revolve, which in turn, by the positive engagement of its serrations with the serrations of the adjacent sleeve K of the pinion J, compels that and the axle B and connected carrying-wheels Ato rotate during the travel of the spring-propelled rackbar from its rearward position to the forward limit of its movement, and thus insuring the rotation of the car-wheels sufficiently to give the car a good start.

Upon street-cars, where the horses are altern ately changed from one end of a car to the opposite end, I simply duplicate and reverse the within-described arrangement of parts.

Having described my invention,whatI claim as new, and desire to secure by Letters Patent, is-

1. In a combined car starter and brake, a

I horizontally disposed rack bar movably mounted on a carrying-rod lattached to the car-bottom and adapted to longitudinal movement thereon, a recoil-spring upon said rod, a pinion loosely mounted on the car-axle and meshing in the rack-face of the rack-bar, a keyed pinion upon the opposite end of the car-axle, said respective pinions having an integral serrated sleeve portion adapted to engage one with the other and forming a ratchet-clutch, a shaft journaled at one end in a bearing upon the car and its opposite end in a movable operating-bar pivoted at its rear portion to the car and at its front end to a vertical manipulating-rod, a pinion keyed to one end of the aforenamed shaft adapted to be thrown into and out of engagement with the keyed pinion on the car-axle, and a pinion keyed to the opposite end of the shaft and adapted to be thrown into and out 'of engagement with the rack-face of the horizontal rack-bar, all combined and operating togetherv i substantially as described, and for the purposes specified.

2. Ina combined car starter and brake, a

longitudinally thereon, carrying the rack-bar forward or rearward longitudinally, a iixed collar on the carrying-rod abutting against the recoil-spring, a loose pinion upon the caraxle adapted to engage with the lower or rack face of the rack-bar, and a keyed pinion at the opposite end of the aforesaid axle, each of said pinioiis having a sleeve portion serrated at its end, the two combined forming a ratchet-clutch and adapted to be held in en gagement one with the other by a coiled spring upon the car-axle bearing against the loose pinion, a supplemental shaft journaled at one end in a stationary hanger and at the other in an angular operating-bar pivotally connected to the car, a keyed pinion upon the supplemental shaft adjacent to the operating-bar, adapted by the moveinentof 'said bar to be thrown in and out of engage- SILAS B. FYLER. [L s] In presence of- WM. C. RAYMOND, HENRY RIEs.
