t `-lMPR0Vl-IhrlENT lN MACHINERY FOR ASCENDING AND DESCENDING INCLINED PiAANES.-

To all Awhom. it may concern: -V

Bc it known that l, (leonor: Escoi, Sizun uns, of the city of Cincinnati, in the county of Hamilton and State ol' Ohio, have invented certain new and useful improven-lents in the -mauncr of constructing and arranging certain parts ofrailways, locomotivesengines, and cars, so as to enable the engine and cars to overcome the resistance of heavy grades on the road., and to ascend and descend thereon with facility andsecurity; and ido herebydeclare that the following is a tnll and exact description thereof. t

The object oi`.my invention is to obtain the requisite adhesion to enable the locomotiveengine and its train of cars to ast-end and descend inclined planes with safety and certaint t'o avoid the expense of heavy grading or eircnitous routes, and to enable the engine torce of ascendingr inclined planes. The nature of the first part of my invention by which I obtain these important ends consists, iirst, in the employing o'f the ,fgmvitatiilg force of t-he train of cars, either in ascending or descendingnr such planes. to give the requisite adhesion in lauch manner as that the adhesion shall increase ot' the train, this being obtained by the conY necting ofthe train with grippingfwheels on the locomotive that embrace a central rail,

where high grades are to be overcome. These gripping-wheels on ascending or descending inclined planes are made. to become driving wheels, they-having their bearings in levers connected together by two opposing togglejoiiitstliat are opera-ted on by the connecting-` ascending the gravity ofv thetrain shall operate'on cne oi` link of the train, so that in the toggles, and thereby-.canse the wheels j to a force proportioned to thegravitating'torce` to li4;ti\ei' 2oixie,

To convert the gx'ippiiig-wliccls are operated on by an auxiliary pair of steam-cylinders of snch capacity aseliectuall y to work olf. in cninnction with theordinarycylinders, the'steain generated in the boiler driving the slow mothe steam gcnerin proportion to the inclination ot' the plane and the weight 5 part ol' the track only creased in 5,367,1latrd einher ittici-1T.

The Second part of my wheels with a spring in such manner as that its tension lshall canse the wheels to grip the central rail, and thus enable the locomotiye to ascend and descend inclined planes without a train, or with a train that is too light to produce the requisite adhesion. or in the event of any accident to thc connections which might prevent the employment of thegravitating force to eil'ect this end. and also at the saine time to admitoi` the lateral play of the loro motive. t A

The third pari; ot' my invention consists in 4the manner ot' communicating motion to theI grippingwheclsi'rom a horizontal crankshaft, the grippingwhcels being allixcd to vertical axles, and this is effected by iueans of evel wheels that slide on the crank-slant, being feathered thereon, and each oi' them being,r forced toward the bevel-wheelsthat are aiiixed to theuppercnds ot' theshal'ts ofthe grippingwheels by ineans'of a spring or springs, the wheels being kept at their proper pitch by lievel-i`aced wheels that make a part ot' or are connected with cach ofthe beveled cog-wheels, by which arrangement the llocomotive will be -t'rec to vibrate on the track-- rails laterally, while the gripping-wheels act on the central v rail.

' The fourth partof my invention relates to ascltacting brake, which is intended to prevent accidents in the event of the breaking or s 1paiatiiig ot`the links by which the respective parts of the train are connected together. 'lliisbrake consists of a pair ot' jointed grippers connected to each car by the longer ends of its levers'fand held up Clear oi the central -rail by a chain which is connected with the bolt of an additional link, and which. when thc main link separates,liberales thcgrippers,

which'thcn fall, so as to canse their jaws to embracethcicentral rail, upon which the gripping-wheels ot' the locomotive operate, said grippcis having their bite upon the rail inproportion to the descending force ofthe cars.

The openings in theslide L. through which the connectingpins' of the toggle pass', are elongated to allow oueor the other of them to be brought into action.

In ordcrto apply the steam with thc forciA required for ascendinl,r the' inclined plane, I employ a second pair of steaurcyiimlers, one ot' which is shown at X, Fig. 1. .lhe pistons of these cylinders are to operate upon-,the shaft t by means of the connectingrods (land when 'the valve isdrawn, which is to admit Steam -nary speed. the quantity ot' stt-am expended will not be decreased, bat will be used with ...its Whole .effect ive force'.

When it is wished to operate upon 'thel grip-A ping-wheels independcptly of the weight or resistance of the train, a. lever maybe allixed, so as to operate by hand'on thc slide Lg'but I intend in general to provide for this contingency by the employment of a small cylinder, Ainto which steam may be admitted fo'r that purpose. Such cylinder may be situated. as

represented by the red lines in Fig. 4, where l is lhocylindcr, the piston of which nced not.

Thisis colmetfted with the boiler by means of a tube, Q. leading,r to the steamways 1li, which may be furnished with a three-way cock, li)- mcans of which steam may be let into thecylinder, so as to operate o n the piston at either' end, and consequently on the toggles., either in asccuding or t-lesc'ci1di:ig,tlie pistoneud of the cyliudcrI beinl` connected with the slide l.. ily this means the grippiugwheels are pressed against the'rail bythe elastic medium. steam, andare made to adjust themselves to its inequalities more perfectly than could be effected by a spring ofstccl orotlier material.

The brakcs on the tender or carsareso constructed and arranged as to be made to embrace the center rail should the link by which they are connected with the locomotive or with each other bebroken when ascending the'l inclined plane, `and the said brakes are thus necessarily combined with the apparatus re- .tlnired for the ascent of the locomotive. Fig. l one ofthese brakes and its appurtenances are shown as attached to a car, and in' Fifrs. 5
