IMPROVEMENT IN' RAILWAY-can courante. i

tudinally and ina vertil `plane through two platforms which are connected together, and also through the coupling devices.

Figure'Z, plate 1, is a top 'view of. a platform withl Hoor removed, having oujir coupling appliedto it. Figure 3, plate 1,'i/s 'ai perspective viewof one of A the combined staples and spring pockets.- Y Figure 4, plate 2, is aside view ofthe ccupliiigdavice for one platform.-

Figure 5, plate 2, is a top view ofthe: same...

,Figure 6, plate 2, is 'a front. elevat-iongof a platform:

and its coupling device.

.` Similar letters of reference indicate ,corresponding parts in the several figures.

This invention relates to certain novel improvements oncouplingsor cars,` wherein we combine, in a mauner hereinafter described, the following important 'and useful features, to wit:

Firstfa buffer spring, which is applied in a pocket formed within a substantialwroughtmetal staple or frame, which `is` secured to two longitudinal beams of the platform, said spring being adapted' to relieve shocks andeoncussions caused'by longitudinal motion of the cars. i i Second, a coupling draw-bar, which is counectedto the said spring at one end, and adapted for receiving through-its opposite flanged end a coupling-pin, such bnr being constructed on its lower side with a strong abutment for receiving. and resisting end thrusts-of a corresponding bar on another car, and on its upper side with an overhang'ing perforated guide for the coupling-pin, which latter passes through the guide `and through a hole made'thro'ugh the bar directly beneath it, and is connected by a link to theheel of the guide, and to a lifting detice, by means of a chain, as

' will be hereinafter explained.

Third, coupling draw-bars, which are broad, Hat .-bars, constructed so that,` when coupled they will lie one over the other, and allow free lateral and vertical, play of the ends of the-cars, and which are perforated coupling-pins through. thiem'back of ythe front beams ot' the platforms; as will be hereinafter explained.

l o enable others skilled in the art to understand ourinvention, we' will explain itsconstruction and operation.

The platforms ofthe cars 'may be constructed in theusual well-known manner. XVe prefertoclevate the same, so as to bring the front cross-beam or bufferbeam Y level, or nearily so, withv the longitudinal door timbers of the car-body, and also to so construct the buffer-beams Y thatthe platforms can be coupled very close together in a train, and proper motion allowed for turning curves.

In the center of the buffer-beam Y a friction-plate, W, is secured, helosw which is the outwardly7aring mouthf'piece or coupling-box' M, bolted rigidly to the lower sides of the platform timbers, and made so aste c allow, free lateral and vertical play o f the cars when coupled. 4

Behind the mouth-piece M is a frame, H, which is bolted fast tothe longitudinal platform timbers, and

constructed so-as to receive and form guides for two .vertical .transverse compression-plates, I, betweenby'means of an eye-bolt, a'. To the front end or eye of the bolt the rear bfur cated end of the coupling draw-.bar A is connected by means of a horizontal transverse pivot, a, which will allow lateral as well as vertical play to the free end of said draw-bar.

The compression-plates I Il are allowed to slide freely, so as to cause the spring to modify shocks of traction as well as thrust. Each'coupling draw-bar A is a flat, broad bar, perforated vertically at b' and b', for the coupling-pins B `B, made4 thicker at its rear end than at its front end,

and provided with iins or flanges on its edges near its frontend.

The front end is rounded laterally, and slightly beveled vertically. rlhe holes b bthrough this bar are slightly oblong, and, when two cars are brought one bar A are directly over the holes of the other bar, so that the bars can be coupled 'by pins B B, passed -through these holes b tb', i

On the upper side of each draw-bar A, near its pivoted end, -a strong abutment, E, is bolted, and on the lower side of the bar, directly beneath the block or abutment E, an. abutment, F, is secured. f The bolts g G are usedas shown in 1, to se cure the ahutments E `E tothe draw-bar.

The bolt G is constructed with a slotted and perforated head', to whichI is pivoted therear end of u stiff link, L, the frontend of which has the couplingpinB pivoted to it, as'` shown in the drawing.

The two abutments E E are intended to operate, in

which a rubber block, K, is compressed and confined together in position for being coupled, the holes of the pins B B can be dropped through their respective holes Ig b, through both drawbars, when the ends of the latter ilnpinge against said abutments.

To the upper side of each abutment E, and bolted thereto, is a coupling-pinA guide, P, whichis a narrow plate', directed forward and upward, and terminating anteriorly in aul eye for having attached to it a liftingchain, 7c.

Just in rear of this chain-eye au oblong hole is made vertically through the guide P, directly4 over thehole b', which is through the-bar A, as shown in ig. l. This hole through the guide receives the coupling-pin B through it, which piu, as before stat-ed, is pivotedA by a transverse pivot to the front end of the vertically vibrating link. or guard L.

The chain 'k 'is carried up and over a pulley at back of beam Y, and attached to one` end of a horizontal rod, N2, which lies in a transverse groove beneath the floor of the platform, immediately behindv therbeam Y, as shown in lig. 2. I

To the outer endof the rod N2 the lower end of a laterally vibrating hand-lever, N, is pivoted, which lever has its fulcrum on standard Nl, and is carried up through au oblong slot made through the guard- -rail T. f

One of the edges of Said slot is notched, as shown in fig. 2, to receive arid hold the N iu place when it is adjusted for holding up thecoupling draw-'bal'.

The upper eudof each coupling-pin B has a ring applied toit by which itv is handled, andthe lower end of such pluis 1ounded"`aud tapered, as shown in the drawing. We' case-harden these pins to prevent them from rapidwear, and to render them easy to lift up or uucouple.

The iinsxor wings afa, on .the edges of each coupling drawba`r,'serv e, in connection with the rear contractedends of the mouth-piece M of an opposite car, to guide the bar centrallyv to its place beneath the coupling, and, at the same time, 'they allow lateral motion of the cars without causing the draw-bar to bind in the mouth-piece. V

A coupling constructed as above desoribed'allows very little slack or lost longitudinal 'motion in cars coupled together, inasmuch as the draw-bars transmit such vall-endwise motion directlyto the springs, both in drawing and thrusting, and operate in eect almost as though a single draw-bar was used, connected at both ends to springs; consequently all unpleasant and injurious shocks and jerks are obviated.

Having described our invention,

What we claim asuew, and desire to secure by Letters Patent, is-

1. The overlapping draw-bars A A, perforated at b b, and furnished with abutments E f, and guides l P, in combination withcoupling-pius B B, and springs K, which springs are fitted in housings H H, and

connected by pivots jara to the draw-bars, the said draw-bars, housings, and springs, being arranged substantially in the manner described.

2. The lifting audhguidiug-plates P P, iu combination with the`overlapping shouldered and perforated draw-bars A A, pins B, and links L, substantially in the manner described.

3. The combination of the buffers W W, drawheads M M, overlapping pivoted and shouldered draw-bars A A, springs K K, guiding and liftingplates P P, and hinged pins B B, substantially. as described. JEAN. O.- FISCHER.
