CAR BRAKE AND STARTER.

SPECIFICATION forming part of Letters Patent No. 410,386, dated September 3, 1889.

Application filed May 8, 1889. Serial No. 310,014. (No model.)

To all whom it may concern:

Be it known that we, AMOS MORONY VER- EKER and STEPHEN MITCHELL YEATES, both of Dublin, Ireland, Great Britain, have invented a new and Improved Car Brake and Starter, of which the followingis a full, clear, and exact description.

Our invention is an improvement in that class of brakes and starters in which fast and loose clutch-sections, springs, and chains are so connected with each other and the axles of a car that the force applied for braking is stored and utilized for starting the car.

Our present combination and arrangement of parts are more particularly an improvement on the invention for which we have received Letters Patent of the United States No. 37 3,624.

Reference is to be had to the accompanying; drawings, forming a part of this specification, in which similar figures and letters of reference indicate corresponding parts in all the views.

'on line am: of Fig. 1.

,formed with ratchet-teeth 13.

Figure 1 is an inverted plan view of the frame-work of a car, representing the same as it appears when provided with our improved automatic brake and starter. Fig. 2 is a similar view of a modified construction. Fig. 3 is a longitudinal sectional view taken Fig. 4 is a similar view taken on line y y of Fig. 2. Fig. 5is a detail view in longitudinal section, illustrating a modified arrangement of the spring-chain. Fig. 6 is an enlarged cross-sectional view taken on linezz of Fig. 4. Fig. 7 isadiagrammatical view of the brake and starter, the spring and the chains connected thereto being removed. Fig. Sis a similar view of the parts, representing them as they appear when the spring is being drawn upon to check the momentum of the car; and Fig. 9 is a similar view of the parts, representing them as they appear when in position to start the car in the direction of the arrow shownin connection with the figure.

e will now refer particularly to the construction shown in Figs. 2, 4, 6, 7, 8, and 9, in which 10 and 10 are the axles, which are supported by the wheels 11 in the ordinary manner, and to which there are rigidly secured clutch-sections or drums 12 and 12, In connection sections that are complementary to the sec tions 12 and 12. Thedrums 14 and 14 are formed with toothed sections 17, and about these toothed sections there are passed chains 16 and 16, the ends of said chains being connected by rods 18, which cross each other diagonally, as shown in Fig. 4, and the chain which passes about the drum 14 is connected to a heavy spring 20, that is arranged as best shown in Fig. 2.

Just beyond the toothed sections 17 there are formed grooves 21, in which rest the ends of yokes 22, that are rigidly connectedto 1evers 23 and 23, said levers being pivotally mounted on studs 24, that extend downward from the car-body; or the studs may be supported on frames carried by the axles.

Beneath the ear-platforms we mount transverse shafts 25 and 25, which said shafts carry rigidly-mounted arms 26 and 26 and 27 and 27, the arms 27 and 27 being connected to levers 28 and 28, said levers extending up to about a level with the car-platform, there to be engaged by treadle- pieces 29 and 29. The ear-platform is slotted and recessed to receive the levers and the treadlepieces carried thereby, and when the car is moving forward the forward lever is adjusted as represented in Fig. 4--that is, moved so that it will rest within the forward recess b of the slot formed in the car-platform, the lever and foot-piece29 resting in the inner recess c at its end of the car.

To the arms 26 we connect rods 30 and 30, which extend and are secured to the levers 23 and 23, the rod 30, which extends from the shaft 25, being connected to the lever 23, and the rod 30, which extends from the shaft- 25, being connected to the lever 23. The opposite ends of the levers and 23 are connected by a spring 31, and the lever 23 is connected to the arm 26" of the shaft 25 bya rod 32, while the lever 23 is connected to the arm 26 of the shaft 25 by a rod 32. The draw-bars 35 and 35" are connected to the rods 32 and 32 by chains 36 and 36. Aninspection of the drawings will show that the rods and 30 and 32 and 32 are mounted to slide within their supporting- arms 26 and 26.

We will suppose that the car is traveling forward in the direction of the arrow shown in connection with Fig. 7. Then if the driver releases the lever 28 the spring 31 will act to throw the levers 23 and 23, (as indicated by the arrows shown in connection therewith,) thus bringing the teeth 13 and 15 of the drums 12 and 12 and 14 and 14 into engagement, and as theteeth of the drums 12 and 14 engage the spring 20 will be drawn upon and the momentum of the car will be checked, the

draft of the horses being slackened at this time. If it is now desired to start the car, the horses in moving forward will draw upon the draw-bar 35, and in so moving will carry the rod 32 forward, and the lever 23 will be turned so as to move the drum 14"to a position such that its teeth 15 will be freed from engagement with the teeth 13 of the drum 12, the teeth 13 and 15 of the drums 12 and 14 being left in engagement, so that the spring 20 will be free to carry the drum 14 forward, and as the drum is so carried forward the hub or drum 12 will be carried forward and the car started in the direction of the arrows shown in connection with Figs. 7 and 9. WVhen the driver releases the lever 28 and the spring 31 acts as above described, the parts will move to the position in which they are shown in Fig. 8, and when the horses draw upon the draw-bar 35 and move the lever 23, as above described, the parts will assume the position in which they are shown in Fig. 9. Should the car be moving in an opposite direction from the one supposed, the action will be the same, except that the parts denoted by reference-figures having exponents would take the place of the parts having reference-figures without exponents, as will be readily understood.

Instead of having the chains connected by rods 18, such chains might be connected by a single rod 18, and held taut upon the toothed section 17 by means of a rod 18", which is connected to a light spring 42, said spring extending to a bracket 43, this construction being shown in Fig. 5.

In Figs. 1 and 3 we illustrate a construction wherein both clutches are mounted upon the axle 10, there being in this case a central drum 44, formed with two sets of teeth 0 and d, and a gear 45, that is engaged by a gear 46, mounted upon a supplemental shaft 47, the drum 44 being also formed with a chainwheel, over which there is passed a chain f, that runs upon the chain-wheel 49, carried by the shaft 47. The drum 44isloosely mounted on the axle 10, and at either side of the drum there are mounted clutch- sections 14 and 14,

that ride on feathers e, carried by the axle 10.

The yokes 22 of the levers 23 and 23 engage the clutch- sections 14 and 14, and the connection with the spring 20 is in this case established by means of a chain g and rod t',

the chain g being held by a chain-wheel h, mounted on the shaft 47. In this case connection between the levers 23 and 23 and the arms 26 and 26 of the shafts 25 and 25' is established by means of rods k and k andl and Z, the spring 31 being connected to arms n, which are connected to the yokes 22. From the above construction it will be seen that if the lever 28 be allowed to enter its recess c the spring 31 will act to throw the two clutch-sections into engagement, the spring 20 will be drawn upon through the medium of the intermediate connections, and the momentum of the car will be checked. If, now, it be required to start the car, a pull upon the draw-bar 35 will act to throw the clutchsection 14 from engagement with the teeth d, the clutch-section 14, however, being in engagement with the teeth 0, so that the spring in retracting will start the wheels 11 in the direction of the arrow shown in connection therewith. If the car be moving in an opposite direotionto that indicated by the arrow shown in Fig. 1, the parts will operate in the reverse order, as will be readily understood.

Having thus described our invention, we claim as new and desire to secure by Letters Patent-- 1. In a car brake and starter, the combination,with the car-platform and truck-axles 1O 10, and the ratchet clutch-sections 12 12 and 14 14, mounted, respectively, fast and loose on said axles, of the chains 16 and 16,wound on the loose sections, the spring 20, connected with one of said chains, the pivoted horizontal levers 23 23, having yokes that connect them with said sliding sections, the spring 3], connecting said levers, the hand-levers 28 28, pivoted and working in a vertical plane through the car-platform, and means for locking them, the connecting-rods 3O 32 30 32 25 25, and shafts 27 27, arranged intermediate of said hand and horizontal levers, all substantially as shown and described, and operating as specified.

2. In a car brake and starter, the combination, with the axles, of clutch-sections rigidly mounted thereon, other clutch-sections held to slide and to turn upon the axles, levers carrying yokes which engage the sliding clutch-sections, a spring which acts to throw the clutch-sections" into engagement,a spring 20, connections between the spring 20 and the sliding clutch-sections, a transverse shaft provided with arms, connections between the yoke-carrying levers and said arms, levers which extend to within reach of the driver, and draw-bars, connection between the levers, draw-bars, and the transverse shaft being established, substantially as described.
