SPECIFICATION formingpart of Letters Patent No. 278,429, dated May 29, 1883.
' Application filed J 1882." (No model.)
To all whom it may concern Be it known that we, WILLIAM B. GUERN- SEY, of Norwich, in the county of Ohenango, and WILLIAM B. TURNER, of NewYork, both 5 in the State of New York, have invented certain new and useful Improvements in Brakes for Locomotives or Railway-(Jars, of which the following is a specification.
Our invention relates to a power-brake; and it consists, first, in mounting brake-shoes directly upon their operating-cranks; second, in a driver-brake for locomotives, in which the brake-shoes are mounted directly on their operatingcranks, as hereinafter described; third, in the combination of brake-shoes mounted upon their operating-cranks, supplementary arms, and connecting-rod, allarranged nearly in the plane of the driving-wheels, as hereinafter described; fourth, in the combination of brake-shoes pivoted on operating-cranks with a system of lever-arms, connecting-rod, an equalizing-lever, and a suitable motor, substantially as herein described. In the accompanying drawings, Figure 1 isa 2 5 side elevation, representing thedriving-wheels of a locomotive with our invention. applied. Fig. 2 is a front view of one of the double cranks employedfor carrying and moving the brake-shoes, as hereinafter described;
A A are boxes attached to the frame of the locomotive behind and in front of the drivingwheels W, respectively. 'Within these boxes are journaled the brake-shafts B B", carrying at their outerjends the arms 0 0, upon the 3 5 outer ends of which the brake-shoes S S are pivoted. On the inner ends of the shafts B B are the brake-operating arms D D; or said arms may be, attached to the shafts outside of I the locomotive-frame. 4o A primary draw-rod is shown at E, connected with a suitable-motor and with each alternate crank-arm D, so as to apply pressure tolthe shoes S on one side of each wheel. The draw-rod E extends to an equalizing-lever,..F, fulcrumed at f in a suitable box, H,
and having hinged to its opposite end a second draw-rod, G, connected to the other alternate arms, D, so that by the pull of the primary draw-rod E an equal and simultaneous 5o movement will be communicated to all the shoes S S on the opposite sides of the-respective wheels. Equalizers of any appropriate form may be placed elsewhereas, for instance, on the levers'D D, or some of them-4:0 effect the same purpose. When the pressure is relieved, 5 5 the shoes are retracted by springs or in any preferred or convenient manner. I
It will be observed that in our improved brake the shoes are not merely operated by cranks, being swiveled directly to them, while another crank-armon the opposite end or upon the same end of the shaft which carries the shoe-crank is used to operate the said ure to the shoes.
Our improved brake dispenses entirely with theneed of hangers,levers, pitmen, and guides, and has neither outside nor overhead connections.
All the shoes on one side are operated by longitudinal rods or chains inside of or below the locomotive-frame, eachrod being attached to the actuating crank-armsof its respective proper motion in like direction, while an equalizer at one end of the system converts a pull at the other end upon one of the rods into a pull upon them both. All the shoes move through equal distances, irrespective of pressure.
In describing the useof separate shor'tcrankshafts on each side we refer, of course, to the application of the invention to locomotivebrakes. It is manifest that it is alike applias above described, or by using through-shafts with a single motor-arm for each shaft, which carries at its respective ends the shoe-arms for the two wheels of one axle.
7 Having thus described our invention, what We claim as new, and desire to secure by Letters Patent, is- I 1. In a locomotive-brake, the combination, witha series of carrying-wheels rigidly connected, so as to partake of each others movements of rotation, of aseries of rock-shafts, each carryinga brake-shoe and fulcrumed upon the vehicle-frame, and a series of actuatingrods connecting alternately with the rock-lemove the brake-shoes in unison and through exactly equal distances, the levers and shoes cranks, but are carried upontheir operating- 6o cranks for the purpose of applying the press- 65 shoes, which have their concavities and their cable to car-brakes either by using short shafts, 8 5
vers, thesystem thus arranged operating to I00 and connections constituting a complete set upon one side of the vehicle, wholly independ ent of the set upon the opposite side of such vehicle.
2. In a locomotive-brake, crank-shafts swivelcd to the vehicle-frame or to attachments thereto, carrying brake-shoes upon one end and attached alternately to longitudinal operative rods or equivalents, the two systems of rods being themselves connected atone end by an equalizer, the whole in such wise as will cause any movement communicated through the rods to move each of the said brake-shoes through exactly equal distances, substantially as set forth.
3. In a locomotive or car brake, the boxes A, A, and H, attached to the vehicle-frame, in combination with the shafts B B, journaled in said boxes A A and carrying arms 0 C, to the outer ends of which the shoes S S are pivoted, and the arms D D, the equalizer F, journaled pivotally in the box H, the drawrod E, connected to one end of the equalizer F and to the armsD, and the draw-rod G,
connected to the opposite end of the said equalizer F and to the arms D, substantially as and for the purposes specified.
