IMPROVEMENT IN CAR BRAKES AND STARTERS.

Specification forming part of Letters Patent No. 125,049, dated March 26, 187

Specitication describing certain Improve wments in (Jar Brakes and Starters, invented by CHARLES M. HINCKLEY, of Boston, in the county of Sui'olk and State of Massachusetts.

This invention is an improvement upon the car brake and starter invented by David M. Moore, and upon which he obtained a patent dated July 20, 1869, and numbered 92,869. My invention relates to an improved method of shipping and unshipping the gear.

ln the accompanying drawing, Figure l is a plan ofthe under side of a car embodying my invention-no car-wheels are shown, as they are not a part of my improvement. Fig. 2 is an elevation, showingthe platform, dash-board, &c., with a piece broken out of the latter to show the gearing, Sac., under the car to better advantage. Fig. 3 is a plan ofthe drum. Fig. 4 is an elevation of the same.

Similar letters of reference indicate corresponding parts.

al a2 are two common varieties of brakehandles. b is the dashboard. c c are cranks or levers, to which are attached the wires or chains d d. d d are chains, cords, rods, or their equivalents, ruiming from the levers c c to the levers e e. e e are levers or cranks bent down into rods ff, which lie in slots in the Wheels g g. g g are the geared wheels, shown in Moores patent, above referred to. his the Wheel, shown in Moores patent, into which the wheels g g mesh. k is the drum, as shown in said patent. ma are flanges extending from the drum k. o is a slot or cut in the drum k, to allow room for the rst link of the chain. p is a short rod or bridge running across the slot o, in which or around which is placed the first link of the chain.O s is the rst link of the chain.

To place the wheels g gin or out of gear with the wheel h, a partial turn of one of the brake-handles is all sufficient. These handles are much more convenient, and take less room in operating than the long levers shown in Moores patent. In place ot' stift' shippers (which must be made ci' such strength and size as to be too heavy for use) I substitute cords, chains, ortheir equivalents, in connection with the cranks c c and bent levers e f. drawing motion, and requires but little strength and no stiii'ness in the shippers d i.` The bent levers ef move the wheels g g perfectly and easily. Handles may be placed at each end of the car.

In connection with my drum 7c I have two flanges, m mboth of which are attached to and a part of the drum. Moore has no [lange upon the drum itself, unless a slight rim at the top might be termed a flange. I propose to make my anges as large as possible Withoutinterfering with the gear, so that there shall be no danger of the chain slipping off the drum. The slot, in which the link s is placed, may be made deeper, if desired, and the rod or bridge p will, probably, be set further in the slot 0. will be no obstacle to the smooth winding ot' the. chain. The drum will be made as thin as practicable, using as little stock as possible, thus giving opportunity for wide flanges.

Ths invention Works finely, practically, and is, in my opinion, avaluable improvement upon Moores patent, above referred to.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-- The arrangement of the cranks or levers c c, shippers d d, and bent levers e f c f,.when placed in combination with the geared Wheels g g, and playing in slots or their equivalents upon the same, substantially as described, and for the purposes set forth above.
