DAVID FREDERICK CARVER, OF BROOKLYN, NEW YORK.

RAILROAD-SWITCH.

SPECIFICATION forming part of Letters Patent No. 578,966, dated March 16, 1897.

Application led July 8, 1896. Serial No. 598,403. (No model.)

To all whom it may concern:

Be it known that I, DAVID FREDERICK CAR- VER, of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Railroad-Switch, of which the following is a full, clear, and exact description.

The invention is especially intended to improve what is known as continuous mainrail switches, that is, switches in which the main rails have an uninterrupted tread through the switch. With this class of switches as now generally constructed any considerable traffic to and from the side line quickly destroys the continuous rail at the inside of the curve, and the present invention prevents this wear; also, I am enabled to accomplish this without any movable part at the inside curve of the switch, the only necessary movable part of the switch being a tongue at the outside.

The invention in its complete embodiment comprises numerous distinguishing features, all of which will be accentuated in the following detail description and then defined in the claims.

Reference is to be had to the accompanying drawings, forming a part of this speciiication, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is a plan view of a switch embody ing my invention. Fig. 2 is a cross-section taken on the line 2 2 of Fig. l. Fig. 3 is a cross-section on the line 3 3 of Fig. 1. Fig. 4f is a broken side elevation at the tongue side or outside curve of the switch, and Fig. 5 is a detail longitudinal section taken on the line 5 5 of Fig. 2.

The inside curve of the switch is indicated by the letter A, and the outside by the letter B, and one of the advantages of my invention as an entirety consists in this: that I am enabled to provide a switch having all the parts stationary at the inside curve, where the continuous main rail O is crossed, and ein'- ploy a tongue at the outside only. The gage of the railway is indicated by the broken transverse line x, while the broken line y indicates the distance between the treads of the main rails of the switch, and it will be seen that the switch is thus spread wide of the normal gage, a feature to be noted, and

I place a riser a within the broadened main rails and preferably inclining upward to the height of the main-rail tread, thus providing a stationary guiding-surface at the inside curve of the switch, whereby the flan ge of the car-wheel will be guided upward.

O' indicates an inside' guard, which, however, is not part of the present improvements.

Further, I provide in connection with the riser a for the wheel-'liange a second riser b for the wheel-tread, this second riser having its point or front end a short distance `rearwardly of the end of the riser a. The riser ZJ is shown as integral with and forming the end of the non-continuous siding-rail c, and the latter and the riser h are within the line of the treads of the continuous'main rail C and overlap the same, this being conveniently provided for by reason of the spreading of the main rails beyond the normal track-gage. will also be seen that I am enabled to make the riser b and the non-continuous rail stationary.

In front of the riser b an outside guard h may be provided with advantage,'said guard overlapping the tread of the main rail O. This serves as a precautionary device to deflect the wheel inward,so that when the switch is closed and the main line open the wheel-flange will take the main line and pass inside of the riser a and not subject the risers to unnecessary wear. I further form on the non-continuous rail c or arrange in connection therewith a guard rail or part c, which also overlap; the mainv rail C by reason of the widening of the main rails.

If, in widenin g the gage, I leave the guard c outside of the line of travel of the wheels passing over the main rail, as usual, the widening will result in leaving the wheel unguarded for a greater distance than in ordinary mates, and to avoid this I arrange the guard e to overlap or partly extend in line with the mainrail tread, as shown.

In connection with the non-continuous rail c and riser b I provide an outside guard-rail f, which extends above the head or tread of the said rail c and prevents the wheels running from the non-continuous rail to the continuous main rail from taking improper di rection.

ICO

. the bed-plate and yet maintain proper resistance to the pounding action on the tongue at the heel. This I accomplish by projecting the pin d from a lateral extension D2, formed on the tongue, and form the hole g forsuch pin in the bed-plate G outside of the tread d of the tongue. Thus a full amount of metal is provided in the bed-plate beneath the tread of the tongue.

The tongue overlaps at its front end the adjacent main rail C2, and instead of bringing the tongue to a point and of leaving the tongue with only its reduced thickness of tread to resist curling I provide a blunt or wide point d2, and also provide the tongue with a downward extension or flange d3 at the inside, as best seen in Fig. 2, such flange merging into the body of the tongue toward the heel. Thus I resist destructive action on the tongue and get a solid bearing against the adjacent rail; also, the tongue shown projects but very slightly above the track and offers little obstruction to crossing vehicles.

In Fig. 3 I have indicated the car-wheelin dotted lines, and it will be seen that the distance between the guard e and the gage side of the continuous main rail C is less than the width of the tread of the car-wheel; and this is true also of the stationary non-continuous rail itself, Where at its front end, as at c', the said rail is less distance from the gage side of the main rail than the width of the wheeltread. A switch having the stationary noncontinuous rail having this relation to the main rail has not heretofore been provided. The stationary riser l) has a similar relation to the gage side of the continuous main rail and the wheel-tread. The result of these three features so arranged is that the least amount of the head of the continuous main rail will be subject to the cutting action of the wheel-flange running diagonally across said rail when the risers become worn down.

In order that the merits of the invention may be understood, itis explain ed that in practical railroad construction when the tongue is placed on the outside it has been heretofore an unsolved problem how to effectively and surely get the flange of the wheel over the head of the continuous main rail adjacent to the inside of the curve. This has been effected in a measure by elaborate systems of moving parts with boxes below the street, which latter have to be cleaned frequently or there must be a special sewer connection when possible. Many of these systems also must have a special locking device to hold parts of the apparatus in place to prevent derailment of the cars when going around curves. My risers and the tongue D guide the wheels clear of the continuous rail C until the wheel- (ianges enter the groove between the tread of the non-continuous rail c and the inside guard c, thereby preventing the wheel-flanges from cutting into the continuous main rail, so that an effective switch is provided in which destructive wearing is overcome and in which all the parts with the exception of the tongue may be and preferably are made stationary, as shown.

In the drawings I have shown the mate as au assemblage of separate pieces about a common girder-rail, but it will be understood that it is sometimes desirable in practice to cast the whole in a single piece with corresponding surfaces for guarding the wheels as well as directing the saine upward and over the main-rail tread, as described; also, it is explained that the main rails may have the broadened gage beginning on a line about at the point of the tongue and extending to the point h', where the riser a reaches the height of the main-rail tread C.

By broadening the gage I am enabled to place my inside riser a between the normal and broadened gage-lines, and also it enables me to provide the immovable riser or rising surface ZJ at the outside of and extending into the tread-line of the main rail in position to receive part of the tread of the wheel before the latter starts to leave the line of the lnain rail, and, further, to give a similar relation between the non-continuous rail proper, c, and the main rail, whereby I prevent the wheel from crowding out or bending over the said non-continuous rail.

It will be further observed that the continuation of the riser a beyond the point a is level with and alongside of the main-rail tread, and this level portion will receive that part of the wheel-tread which is between the flange of the wheel and the part of the tread which is on the main-rail tread.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl.
