Application filed August 12,1895. Renewed December 21, 1896. Serial No. 616,520. (No model.)

To ([JZ 70710711 it 7I7/ILfI/ concern.-

Be it known that I, CHARLES H. SHERWOOD, of Utica, in the county of Oneida, in the State of New York, have invented new and useful Improvements in Railway-Switches, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to a new and improved construction in railway-switches.

The object is to arrange a branch or switch extending from a main track in such a manner as not to disturb the main track and at the same time provide a simple, efficient, and reliable construction; and to that end the invention consists in the novel organization and combination of the component parts, as hereinafter fully described, and set forth in the claims.

The invention is fully illustrated in the accompanying drawings, in which Figure 1 is a plan view of a section of railway-track equipped with my improved switch and mechanism for operating the same, showing said switch closed or lying on the maintrack rails. Fig. 2 is a similar view showing the switch open to the main track. Fig. 3 is an enlarged sectional view on line X X in Fig. 1. Fig. 4 is a similar view showing a slight modification of the arrangement of one of the cross-bars which connect the switch-rails. Fig. 5 is an enlarged sectional View on line Y Y in Fig. 1. Fig. 6 is an enlarged detail side view of the end portion of the end rail of the switch and adjacent portion of the maintrack rail. Fig. 7 is a sectional View on line 3 3 in Fig. 5, looking in the direction of the arrow. Fig. 8 is a perspective View of one of the shifting rails or frog-sections of the branch or side track at its intersection with the main track. Fig. 9 is an enlarged detail view of the switch-stand, shown partly in section, and showing the switch-lever and its connection with the track-rail. Fig. 10 is a vertical transverse section of the switch-stand, showing more clearly the construction of the mechanism within the same. Fig. 11 is a view of another side of the switch-stand, showing in detail its connection with a portion of the mechanism connected to the aforesaid locking-rail.

Fig. 12 is a horizontal transverse section on line 1 1 in Fig. 9. Fig. 13 is a View on line 2 2 in Fig. 9, and Fig. 14 is a perspective view of a portion of one of the shifting switch-rails.

Similar letters of reference indicate corre' sponding parts.

a a represent two stationary rails of a section of the main track, and extending therefrom is a branch track consisting of the stationary rails b b and the laterally-shifting end rails b 11', secured at one end to the rails b b by means of a flexible fish-plate b.

The bases of the end rails b 1) adjacent to the main rails are beveled off toward the end in order to allow said rails to lie 011 the main rails when shifted toward the same. The heads of said rails are also beveled on top toward the free ends and also on the inside toward to the ends, as clearly shown in Fig. 16 of the drawings. To the adjacent sides of said end rails are secured plates 9 9, having formed thereon ears g. Said rails are connected by cross-bars c e and f f, extending, respectively, from the inner and outer rails and connected together by a bolt f. The main rail (4, nearest the switch-stand, is provided with slots 0 0, through which the bars ff pass, as shown in Fig. 3 of the drawings, or said bars may be brought under the rail a and fastened to the outside of the outer rail 1), as shown in Fig. -i of the drawings.

At the intersection of the branch track with the main track the branch is formed of two laterally-shifting rails or frog-sections c and d, secured to the rails 19 in the same manner as the end rails 19.

The base of the rail 0 adjacent to the rail a is cut off, and the free end portion of said rail is bent away from the rail a, as shown at s", for the purpose hereinafter described.

To the inside of each of the rails c and (Z are also secured plates g 9, having ears 9 formed thereon similar to the plates on the end rails I). From each of said ears, extend ing across the track, is a cross-bar 0 and pivoted at its opposite end to one of the arms of a T-shaped lever It.

On the outside of the end rail Z) nearest the switch stand are secured two of the plates g, having the cars g, and from one of the rails I) Z) and are formed similar to the end rails I) Z). Said rails 19 p are connected by crossbars 0 o in the same manner as the aforesaid end rails, and from the outer of said rails extends a bar a, pivoted at its opposite end to one of the arms of a suitably-supported bell-crank lever m, and from the other arm of said lever to the aforesaid third arm of the T-shaped lever extend two rods Z Z, also adjustable by a turn buckle 3. All of said rods run in guides or bearings, consisting of a support or bracket a, having two rollers Z) I) journaled therein, between which said rods slide, as clearly shown in Fig. 5 of the drawings.

At a suitable distance from the end rails b I) is arranged. the mechanism for shifting said rails, which is constructed as follows: WVithin the hollow case A is journaled a sleeve 61'', resting in the seat 9 at the top of the case, and within said sleeve is a post 0. Said post is provided with a vertical socket or guide f in which is located the vertically-slidin g rod ct'. Said rod and sleeve are connected by means of a pin 6, which passes through a vertical slot f, formed in the post. On the lower end of said post is secured a laterally-swinging lever b, having pivoted at its free end a horizontal rod t, extending part way toward therail way-track. Extending from the other of the aforesaid plates on the outside of the end rail Z) nearest the switch-stand and part Way toward the switch-stand is a bar f. Said bar is adjacent and parallel to the rod t. On both the rod and bar are arranged, respectively, stops t and f, and on said rod and interposed between said stops is a spring 15.

To the upper portion of the post 0 is socured a lever 6, connected to the sleeve 61 by two vertical arms 1'. Said mechanism is clearlyshown in Figs. 1 and 2 of the drawings.

The operation of the herein-described mechanism is as follows: The lever 6 being raised thereby draws up the sleeve 6 out of its seat 9 and the rod 64", connected thereto by the pin as aforesaid. The lever e is then swung either to the right or left, carrying with it the post 0, and by means of the lever 19, the lower end of said post 0 and the rod t and barf, the rails Z) Z) are shifted on and off the rails to a. Said lever is swung quarterway around and then pushed down, thereby forcing the sleeve back into its seat to lock the same.

The lever c is preferably locked in its normal position by means of a pin t in the side of the post 0" and having an eye for the re ception of a look, as shown in Fig. 9 of the drawings.

From beneath the switch-stand and extending toward the railway-track is a rock-shaft a, mounted in suitable bearings it' and having secured on one end adjacent to the track a vertical arm uand near the other end portion a horizontal arm it of the form of a forkto receive the lower end portion of the vertical rod a of the aforesaid switch mechanism, and which is held between two collars r it, formed on said rod, as shown in Figs. 9, 10, and 11 of the drawings.

Along the outside of the branch rail Z2 nearest the switch-stand extends a railr', mounted on vertical arms (1 q, movably pivoted to the rail h, as clearly shown in Fig. 5 of the drawings, and from the aforesaid vertical arm a on the rock-shaft u to the adjacent arm (1 extends a rod r. The purpose of the rail 4*, rod 4", the rock-shaft M, and its connection to the aforesaid .rod 60" of the switch mechanism is to prevent lifting of the lever 6, connected thereto, as shown in Fig. 10 of the drawings,

to operate said mechanism to shift the end rails off from the main rails a when that portion of the branch track along which the rail r extends is occupied by a car or engine, at which time the rail 1' is prevented by the wheels of said car or engine from rising.

The hereinbefore-described derailing-rails p p are for the purpose of throwing off a car moving over the branch track toward the main track when the end rails I) Z) and rails c d are oif from the main track, as shown in Fig. 2 of the drawings. To prevent said car from blocking the main track, said derailing-rails are shifted on the stationary branch rails when the other shifting rails are shifted off from the main-track rails, and vice versa, as shown in Figs. 1 and 2 of the drawings.

hen a train moves over the main track from the left when the switch is in the position shown in Fig. 1 of the drawings, the

- flanges of the wheels strike the bent rear end portions of the rail 0 and throw the same off from rail a, and by means of the cross-bars 0 o and lever 7c shifts the rail d, and when the flanges of the car-wheel strike the end rail Z) farthest from the switch-stand said rail and the corresponding end rail are thrown off" from the main rails to a, said end rails being connected, as aforesaid, by the cross-bars e f. Said shifted rails are all forced to their normal positions by means of the spring 25, bearing against the stops t andf, respectively, on the rod and bar f, secured to the outer end rail, all as hereinbefore described.
