TO ALL WI-IOMl IT MAY CNGERN:
`Be it known that I, THoMAsB. GOMINS, Jr., of Lowell, Middlesex county, llassaohusetts, have invented a new and' improved Car-Brake; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in Athe art to make and use thc salue, reference being had to the accompanying drawings, forming a part of this'specication, in whichi p i Figure 1 represents a side elevation" of a car, to `which my 'improved brake is applied. Figure 2 is a bottom view of the same. Similar letters of reference indicate corresponding parts. 1 j This invention relates to an improved car-brake, which is soarranged as to bear with more than usual jpower upon a point onlth'c periphery of the wheel, while the pressure Ais still increased by theapplication of a spring7 which, although it serves to increase the pressure of the brake, still prevents the same from being dull, and makes the whole elastic, and' more durable and e'ective than the brakes new in general use. V
Y A represents the platform of .a railroad car, and B B are the wheels, which are secured `to their axles C C, p ythat hangin boxes D D, as shown, and all et' which parts-ere arranged in the usual manner. E represents the shoe-hars, which are suspended from springs a a, and' operated by a vertical rod, b, which is connected with' a horizontal bar. c, that is attached at one end to a lever, CZ, as shown. The latter is pivoted to one shoe-bar, and to its lower end isl attached another horizontal bar, e, which connects"with a bolt,- f, and passes through the opposite shoe-bar, a'sshown.' Between the outer head of" the b oltf and the shoe-har through which it passes, i
is arranged a spiral or other spring, g, which has a tendency to throw the shoe against the wheel, and which, when thc shoes are drawn a-gainstthe wheels, byre'volving the rod b, increases the pressure 0f the same against thc periphery of the wheel, but' also prevents sudden shocks, and insures the elasticity of the apparatus. The spring further prevents the wheels from sliding on the rail Without turning, as when so much power is applied that the dead weight oi' the car is pulled, the spring will giveA enough to let the wheels revolve. Fare the shoes hinged 'tc the ends of the shoe-bars, as shown.` The upper part of each shoe, when the brake is applied,
bearsagainst the wheel, and in the lovferpartof each shoe an eccentric, G, is pivoted, which `also hearsagainst` i the wheel. The wheel acts uporL the eccentric, andv turning it, (as `shown inired lines on the left-hand sigle of g 1,) throws eti' the'lower end of the shoe and causes the upper end of the same to bear or press with increased power against the wheel, thereby making a much more effective brake than 'the old ones are, which bear with whole surface against the wheel. When released fromlthe'wheel the eccentric hangs down, as shown on the right-hand side of iig. 1. As the wheel turns the eccentric the upper end of the shoeiis forced against thewheel, andthe brake is thus partly self-acting, not requiring any more turning of the rod b after the` eccentric oncevcomes in Contact with the wheel.
`I claim'as new, and desire to secure by Letters Patent- Y y p l. The eccentric G, when secured to the ends of theshoes l", substantially as herein shown and described! 2. The construction and arrangement of the vertical springs a supporting the shoe-bar E, horizontal har e e, lever (l, and spring g, between the `cuter head of the, bolt j' and shoe-har E, as herein setfortlrfor the pnr-` pose specified. i
