RAILROAD-SWITCH.

SPECIFICATION forming part of Letters Patent No, 317,599, dated May 12, 1885.

Application filed July 11; 1884. (No model.)

To all whom itmay concern.-

Be it known that I, MARION WALLIoK, of East Germantown, in the county of Wayne and State of Indiana, have invented certain new and useful Improvements in Railroad- Switches; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in ithe art to which it appertains to make and use the same.

My invention relates to an improvement in railroad-switches, the object of the same being to provide a switch which shall afford an uninterrupted rail-face on both the main and side 1 tracks;'a further object being to provide a switch which shall be closed by the wheels of the engine on the main track,if carelessly left open; a further object being to provide a simple and inexpensive switch which shall 2 embody the most effective safeguards against accident.

With these ends in view my invention consists in certain features of construction and combinations of parts, as will be hereinafter described, and pointed out in the claim.

In the accompanying drawings, Figure l is a plan view of the switch closed, and Fig. 2 is a plan View of the same open.

A represents the rails of the main track,

0 which are stationary, and a the movable rails of the main track, which are bound together by the cross-tie B,and are constructed to slide laterally a little more than the width of a rail, as is usual in switches.

The rails of the side track, I) Z), the former outside of and the latter betweenthe rails of the main track, have their ends situated near to and the same height of the rails A at the ends of the rails a. The short rail b leads 0 from the end of the rail a diagonally across the main track, gradually rising until it reaches the frog-section G,where its face is two inches (more or less) above the face of the main railA. The rail b gradually rises in conformity to the rail Z2, and is stationary, as is usual.

The frog-section O is stationary, and consists of a solid plate of metal set with one edge in contact with or in close proximity to the in her stationary rail A, the edge next to said rail A being sufficiently thin to allow the procar to pass over it without touching it.

On the top of the plate 0 is pivoted a short bar, 0, the free end of which forms a continuation of the rail 1), the bar cbeing held in this position by means of aspring-arm,c,which acts upon its side, and admits of its being swung away from the end of the rail b by the pressure of the movable section D of the frog. This latter consists of a rail-section located on the opposite side of the inner rail A from the section 0, and having one end pivotally secured to a tie, and the free end cut away underneath in such a manner as to allow said free end to swing over the inner rail A and register with the end of the rail 1), and when in this position. rest in contact with the face of the said rail A.

A shouldered V-shaped metal plate, E, is secured to the cut-away portion of the section D, forming a bearing for the same on the inner rail A, and resting with its shouldered portion alongside of the rail A when the switch is open. The construction and operation and purposes of the sections 0 and D are fully set forth in Letters Patent No. 295,844, granted to J. B. Rohrer and myself, March 25, 1884, and a further explanation of the same is dispensed with here.

The switch-operating mechanism consists of two bell-crank levers, F and G, pivoted to blocks or ties f and g, respectively, and connected by the rod H. The lever]? is also connected to flanged plate E by the rod h, passing beneath the rail 1), and thelever G is connected with the cross-tie B by the rod k.

A double crank, L, is journaled in a suitable box, Z, in a block on one of the ties, one arm of said crank being pivotally connected to the end of the cross-tie B by the short connecting-rod m, and the other provided with a ball or block of metal, M, which serves to hold the crank L in a horizontal position in either direction, as the case may be, and thereby hold the switch in closed or open adjustment.

The switch, as will be readily seen, is operated by throwing the crank-arm having the weight secured thereto from right to left or left to right, as may be required, this motion of the crank L simultaneously sliding the rails a and the movable frog-section'D in opposite directions, and thereby opening or closing the switch. It will be observed that when the siding is open the movable frog-section rests over the rail A. A train approaching the switch on the main track, the ends of the rails of which are now disconnected, will automatically close the switch by the contact of the wheel with the movable section D, the gradual pressure upon which swings the said section D off the rail A, and the motion being communicated to the cross-tie B, through the levers and connecting-rods, throws the rails a into connection with the rails A and allows the train to move on without accident.

From the above description it will be noticed that my improved switch is simple in its construction, none of the parts employed being of a fragile nature or difficult tomake, and that the whole is capable of a quick and easy adjustment.

It is evident that slight changes may be made in the form and construction of the several parts without departing from the spirit and scope of my invention; hence I do not wish to limit myself strictly to the construction herein set forth; but,

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

In a switch, the combination, with a stationary frog-section provided with a springpressed cap, and a movable frog-section adapted to swing over the main rail and rest on the said stationary frog-section and main rail, of a sliding main-track section connected with the movable frog-section, whereby either section operates the other, substantially as set forth.

In testimony whereof I have signed this specification in the ing witnesses.

MARION WALLIOK.
