. IMPROVMBNT IN CENTRE-RATE FOR %Image-;chest Be it known that I, GEORGE W. BNNETT, of White Haven, in the county jof Luzcrne, and State of Penn sylvania, have inv ented h. new nud improved ;Gentrc-Phte for Cars; and I do iereby dcclnre the following to he& fuli,'clear, and exact description of the same,-suhcient t o enable those ,skillcd in the art to which my iuvention appertains to make use of it, refero'n'ce being had to' ;uceompznyin g (l-cwings, fo'ming part otthis' Figur 1 is a. vertical section through the line w z of fig. 2; Figure 2 is a horizontl section.

The object of this nvention-is to provide a centre-plote which 'will prevent the trucks frouq shearih g ofi' of ;the road in turuinge short curvc, and theroby dispense with safety -chains.

The centrelate'is com oscd of two horizontal latcs, A A', united nt their centre hy the verticz'llkin P P P eirtle' wl'i l ri-ing, rises from the loj'er pinte, A", and from the upper plate, A, another cireuler mn, a,

4 just large enough to fit inside of the formen,- frojects (lownward. The upp'er plote is placed upon the loweronc,

the ring a fit ting within the ring a', and the weight of the npper place, `and the bolster which it supportsyresting upon the rings, :s shown in fig; 1. Collars a a" ure .cast at the centre, immediately around the king-holt,

and in contact with it, which support the centre 'of the 'pinte ancl st'engthen the kin -bolt. Recesses c c are' provided, cut in the iuner surface of the outer well, as shown in fig. 9, and cor'rsponding projections, c' c', are

cast upon the outer side of the inne"wallfentering the recesses c c, when the-pi'z'tes ure in position, and per- 'mitting a certain amount ofmotion, and no more, to the plates A A, and 'the bolsternnd truck. The lower plate is ttached to the truck, and the upper one to the car, and therefore' the swinging of the car .uponthe truck, and'the turning ofthe lutterunder the egi', ore confined within the limits `nll'nired by the motion of the projections in the recesses c 0.( The extent to which the 'truck will tui-'n can .thus' be re ulated by casting the re'cess es longer oishorter, and the p'ojections wide' or na'rower. Flanges F F ere east along the edges of the plates on the upper and under side of thdevice, which fit' ciosely to the sides of the holster, and through" which the centre-pinte may be holted to the holster. The space within 'the outerring forms a tight cup whichg is to be filled with 1ubricating-fluid. V i v V l By 'the use 'of this device t s evident that the motion of the trueks may be solimitedthat the danger of" their .running of the track'n rounding short curves will bematerinlly diminish'ed, sothat safety-Chams and other similar devices may he dispensed with, and the car he' constructed nt less expens than heretofore. Having thus descrihecl thy invetion, what I claim as new, and desire to secure hy Letters PatenQis- The combiuation of the rings a a', having the reeesses c c and projectionsc'cl,operating in connection With ech other when used in a centre-pinte for cars, substnntally :te and fer thepu'rposes specified.
