RAILWAY-CROSSlNG.

SPECIFICATION forming part of Letters` Patent No. 337.253. dated March 2. 1886.

Application filed November ifi, 1885.A

To all whom t may concern.- A

Beit known that I, MARTIN A. DILLEY, a

siding at Vasepi, in the county of St. Joseph, in the State of Michigan, have invented a new and useful Railway-Crossing, of which the following is a specification.

My invention has relation to improvements lines of rails cross each other at about right angles. In crossings of this character it is necessary to provide ways at ythe points of intersection of the rails for the passage of the flanges of the wheels, the rails being broken at these points, leaving openings wide enough to cause a heavy jar on the ends of the rails and foundation, and to have a damagingv effect on the engine and cars. The ends of the damage to the cars is often immediate and apparent, and always certain in time. I seek to overcome these eiiects by interposing rails a plug, which iills the space, and which may be vertically reciprocated to set with the top of the rails or to drop below and leave the space open, the object being to provide a traversed line of road shall for the time being be made continuous; second, to provide means for operating the movable sections or parts of the crossing with certainty; and, third, to profor giving visual notification to the approaching train of the condition of the crossing.

My invention therefore consistsin the novel construction and combination of parts, as herein the claims made hereto, as required by the statute.

I attain the objects of my invention by the mechanisml illustrated in the accompanying Figure lis a plan view of the crossing with the shifting'mechanism, a part of the latter being broken off. Fig. 2is a side view of the Fig. 3 is a longitudinal shifting or hand levers and connections.

Serial No. 182,856. (No model.)

In the drawings like parts are identitied by like letters of reference.

The letter A designates the foundation-frame of the crossing. This consists of substantial timbers laid at right angles and secured together to present a plane top face. gle of the frame is cnt out to form seats a, for

Each anthe plug-frames to rest in, as hereinafter detunity for arrangement of the mechanism ofA the plugs.

The letters B designate the rails; the letters B the fixed crossing, laid between the intersecting rails of the lines of road, and the letters B2 designate the wing-rails of vthe crossing. All of these are of ordinary construction, and laid and secured as usual.` In the center pieces or plates, b, in the spaces between the terminals of the line-rails and the terminals of the line parts of the wing-rails, are formed apertures b,throughwhich the plugs are passed and in which they move.

The letters C designate the plug-frames, adapted to be disposed in the seats a of the frame. rectangular construction, and consisting of a bottom piece, c, to which are secured the side pieces, c', having the top c2 rmly xed thereon. This top piece, preferably, is extended to project over the side pieces and fasten on the foundation-timbers of the frame. Forming a part of the top, or secured thereto, is a block, c3, of such thickness as to reach down on the slides of the plugs, and of such width as to leave a space Aon each side between the sides of the frame, for the bell-crank levers to operate. Through the top piece and block are formed two vertically-arranged holes or ways, c, in which are placed two plugs, c5 c, the upper ends of which are arranged in the apertures b in the iiange-spaces in the crossing. On each side of the block cs is pivoted I have shown these plug-framesof a bell-crank lever, el, one arm of which has a pivot projected through a slot, c, in the block and into the stem of the plug, and the other arm, el", is detachably connected to the slide, so that as the slide is drawn to raise the plug the crank-lever will follow it by the connection to the plug, and when the slide is pushed back the lug on the side of the slide wil run in the slot of the arm of the lever and push it back, thus assuring the positive movement ofthe plugs.

Theletters cldesignate the slides which op crate the plugs. These slides are horizontally arranged in the bottom of the plug-frames, and consist of a fiat bar having fixed or formed thereon a step or plugseat, c, made with an inclined forward end, c, whereby when the plug is seated on the forward portion of the bar and the slide is drawn to raise the plug it will ride up the incline and be easily lifted. To limit the forward movement of the slides, a stop-bar, c, is projected across the plugframe over the forward portion of the slides,4 as shown, and the foot of the inclines abut against this bar.

`The letters D designate cross-bars secured at the intersections ofthe timbers of the foundation, and having at their intersection afixed pivot, upon which arejournaled two disks, d d, arranged one above the other; and to the outer part of these disks are attached one end of the rods d2, the other ends being attached lo the slides under the plugs. To each disk is fixed a lever-arm, da d, to which are connected the shifting-rods d5 d6, the other ends thereof being connected to the respective hand-levers. In the rods d5 and d6 are takeups, substantially as shown, to adjust them, and permit contraction and expansion without detriment. At a suitable and convenient place, in any way secured, is a `lever-frame, E, having pivoted therein hand-levers er e', provided with sliding pawls or other proper means for holding them in a set position. Between the sides of the frame is mounted a bench, e, upon which is pivoted a lockingplate, e3, which is kept in a normal position by a spring, e4, and returned to such position when turned to either side and released. lIhis locking-plate is of such width that it will admit one of the hand-levers to slide between its edge and the-inner face of the frame, but not both levers at the same time, and is so arranged that when one lever is thrown back the free end of the locking-plate is crowded over to the other side of the frame, and the end sets against the edge of the hand-lever, and locks it in that position against manipulation until the other hand-lever is thrown forward and the locking-plate is sprung from contact with the lockedhand-lever. rlhis arrangement prevents the watchman or tender from throwing both hand-levers at once, and

Valso prevents him from throwing the normally-disposed hand -lever when the other is thrown back.

The letter F designates a si gnal-standard,

the top of which is pivotally secured a signalfoundation are the sliding bars fT f8, having` connecting-bars f9f1", running to the handlevers. Each of these sliding bars has a hole, f, into which the ends of the rods suspended from the signallever project, lrespectively,

and lock the slide, and consequently the handlever and apparatus, until-the signal is turned and the rod is withdrawn from the slide.

The signal-lever is set and held in any of the` desired positions by means of a pin which `is passed through a hole inthe arm of the levert` and into the frame on which` the leveris aty.

tached, substantially as shown.

The operation is as follows: The normal :po-`

sition of the apparatus is with the hand-1e-` j vers projected with their hand ends inthe,

direction of the crossing. faces of the plugs in thespaces of the cross-A ing below the top faces of the rails, and the j This leaves thetop spaces open in both directions, free for ,"wildf` cat7 or unannounced trains.

` Ico plan shown in Fig. l, then the handlever operating the plugs in the vproper spaces is, thrown back, operating the disk and drawing i the slides `under the plugs, raises them into` the spaces, and makes the rail as even as As trains must await the signal at crossings of roads at grade, i so here, and after drawing the hand-lever and though integrally continuous.

forcing the plugs in position, the watchman or tender throws the signal-lever until thev signal displays the proper notice for the train` to proceed. After this train has `passed over,

the signalis returnedto position and, the le-` ver thrown back to the normal position. To operate the other line orplugs is but a dupli-` cation of action, it being borne in mind that IIO different signals are fixed upon to signal trains.;

on the different tracks. c j

`It will be noticed that when the plugs are lifted into position, and the signal disposed to indicate the fact, one of the bars of the signal-lever is projected through the holeinf.

the slidingbar at the base of the signal-standard, as shown in Fig. 2, and locks, the hand-` lever in the thrown position until the signal;`

is changed and the depending bar lifte'd up i from its seat in thesliding bar. It will further j be seen that the floor of the plug-frame is horizontal, and that the slides therein are laid di-i rectly on the door and have direct contact with the ends of the plugs, and these, being; fitted to the apertures through which theyn move, are sustainedin vertical positionthereby, their projecting parts being sustained in the direction of the force by the vertical ends of the rails, and they have at all times a solid foundation.

The mechanism is positive in its action, and so simple in construction that it cannot well fail to do just what it is purposed for. The plugs may be rounded, but it is evident that if made to t the shape of the space between the rails they are the better.

I am aware that a railway-crossing has beenI made wherein vertically-arranged plugs are placed in the flange-spaces of the tracks and raised by a cam-lever mounted on ashaft, one end of said cam-lever engaging with a shoulder on the plug to raise and lower it, and the other end of the cam-lever operating to slide a plaue-supporting block under and from under the plug.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The combination, with a foundation of a railway-crossing and a fixed crossing arranged thereon, having apertures between the adjacent ends of the line-rails and the wing-rails, of plugs movably disposed in said apertures, slides arranged under said plugs, formed with sections of different heights with an incline between them, and means, substantiallyas described, for reciprocating the slides, whereby the plugs are raised and lowered, substantially as described.

2. The combination, with a foundation of a railway-crossing and a fixed crossing arranged thereon, of frames seated in the angles of the 'crossing roads, plugs vertically arranged in ways formed in the frames and adapted to slide in the spaces between the crossing-rails, slides having sections of different heights with an incline between them, and means, substantially as described, for reciprocating the slides, whereby the plugs are raised and lowered, substantially as specied.

3. The combination,with the foundation of a railwaycrossing and a fixed crossing arranged thereon, of frames seated under the angles of the crossingroads, plugs vertically arranged in ways formed in the frames and adapted to slide in the spaces between the crossing-rails, slides having sections of different heights with an incline between them, means, substantially as described, for reciprocating the slides, and a bell-crank lever pivoted to the frame and having one arm connected to the plug and the other arm to the slide, whereby the plugs are raised and lowered, substantially as described.

4. In combination, the foundation-frame having seats formed at the intersection of the timbers, the fixed crossing secured thereon,

plug-frames arranged in the seats in the foundation, slides arranged horizontally in the' frames and formed with a higher and a lower section or seats, plugs vertically disposed in ways in said frames and in the spaces between the line-rails and the wing-rails, a bell-crank lever pivotally attached to the frames and having one arm connected to the plug and the other arm detachably connected to the slide, disks pivotally supported in the center of the crossing and having rods connected to the slides, levers and rods connected to said disks, and hand-levers to rotate the disks, substantially as described, and for the purpose stated.

5. The combination, with a railway-crossing having vertically-moving plugs between the spaces ofthe linerails and the wing-rails, and mechanism for raising and lowering the plugs, of hand-levers connected to the shifting mechanism, and a locking-plate pivoted between the hand-levers and arranged to lock the undrawn hand-lever in normal position when the other hand-lever is drawn back, substantially as described. I

6. The combination,with the crossing mechanism, substantially as described, the hand5 levers, the signal, and the signal-leverrprovided with depending rods, of the sliding bars at the base of the signalstandard, having perforations to receive the ends of the suspended bars, whereby the apparatus is locked in position when either set of plugs is lifted, substantially as described, and for the purpose stated.

In witness whereof I have hereunto set my hand in the presence of two attesting witnesses.
