CAR-STARTER.

SPECIFICATION forming part of Letters Patent No. 336,232, dated February 16, 1886.

Application tiled October 29, 1885. Serial No. 181,214. (No model.)

To all whom t may concern:

Be it known that I, GEORGE B. HATNEs, of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Car-Starters, of which the following is a full, clear, and exact description, that will enable others to make and use the saine, reference being had to the accompanying drawings, forming a part of this specification.

rIbis invention relates to an improved device for assisting the horses or other motive power in starting a street-car and in overcoming the dead stop or weight of the same, as will be hereinafter set forth.

Figure l is a plan of the under side of acar embodying my improved features; Fig. 2, a "ertical central longitudinal section; Fig. 3, an enlarged detail; Fig. 4, a transverse sectional detail in the plane44, Fig. 5; and Fig. 5, a longitudinal section in the plane 5 5, Fig. 4.

Referring to the drawings, A represents the under side of a car, A A2 the car-axles, and A3 the truck-wheels.

In Fig. 1 two draw-bars are shown and the improvement illustrated in duplicate. This arrangement provides means for the car being drawn from either end, and also the coupling together'of two ormore cars, as circumstances may require.

When the car is turned around at each end of the route, but one bar is necessary. When a ear is provided with two bars, they are arranged close together in the center, as shown in Fig. l.

As all my improved features are used in connection with a single bar, a description of one will answer for both, the same reference-characters being employed on duplicate parts.

The draw-bar B runs the entire length of the car,and is adapted to have a limited longitudinal or endwise movement independent of the car, and is arranged a little below the bottom of the same, leaving the space between the two, as shown in Fig. 2. The bar is supported at the ends in relation to the ear by the cleat-brackets a a. The bar is also further supported and stiffened by the brace-rod B', which connects the two bearing-blocks aa3,in which the draw-bar slides, and the braces B2 B3, connected at one end to the blocks a2 c3 and the opposite ends to the axles, as shown in Fig.2.

l The bar B is constructed in three parts and hinged or pivoted together at aa, which form of construction renders the barless rigid, and adapts the same to conform more readily to the movement of the car, and thus relieve the line of draft from the jar incident thereto.

The ratehet-wheels C C are rigidly mounted on the axles A A2 and placed in the longitudinal center of the same. the draw-bar that moves back and forth above the ratchet-wheels is provided with the elongated slots b b, in which is located the pawl b2, pivoted to the draw-bar.

the draw-bar, serves to return the same to a normal position when the car comes to a stop, as illustrated in the drawings, in which posi tion the pawl or pawls b'Z are adapted to engage with the ratchet-wheels when the motive power is applied to the draw-bar, thereby causing the truck-wheels to begin to move and make a partial revolution before the power is transfer-red to the car proper. When the draw-bar has compressed the spring D and reached the position in which it is held by the motive power, the pawl or pawls bl become disengaged from the ratchet-wheels, and the spring el prevents the same from having a clicking contact with said wheels as the car moves along in the usual manner. When the strain is relaxed on the draw-bar, it is again returned to a normal position by the means described, and when the motive power is again applied the pawls engage the ratchet-wheels in the same manner, start the truck-wheels rolling, and relieve the power of the dead-weight, and so ou as often as the ear is stopped.

The spring D not only returns the draw-bar to a normal position, but also relieves the horses or other power of any jerk or jar incident to starting, as the spring is very gradually compressed.

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

l. In a car-starter, the combination, with a draw-bar adapted to have an independent endthe cleatbrackets a a, the bearing-blocks a2 as, the brace-rod connecting said blocks, and the brace-rods B2 B3, having one end of each atwise movement relative to the ear proper, of

That portion of 6o The spring D, placed upon the draft end of tached to said blocks and the opposite ends to the ear-axles, whereby said draw-bar is supported in position, substantially as set forth.

1o draw-bar to a normal position, the paw] or pawls b2, the springs d, the ratchet-Wheels C C', the axles AA2, and Vthe truck-wheels, all constructed, combined, and arranged to operate substantially as and for the purpose set forth.

GEORGE B. HAINES.
