To all w/wm it may concern.-

Be it known that I, EMANUEL HENRY THonNE, a citizen of the United States, residing at Hagan, in the county of Tattnall and State of Georgia, have invented new and useful Improvements in Railway-Switches, of which the following is a specification.

My invention pertains to railway-switches and it has for its general object to provide a simple and durable switch embodying such a construction that the switch-rails may be quickly and easily thrown as an entirety on and oil the main-line rails, this being materially advantageous, since it assures a continuous and unobstructed main line when the switch-rails are in their idle position and enables the switch-rails in such position to de rail cars in the event of the same tending to casually pass from the siding to the main line, where they would be liable to cause disaster.

Other objects and advantages of the invention will be fully understood from the following description and claims when the same are read in connection with the accompanying drawings, forming part of this specification, in whi ch Figure 1 is a plan view of my novel switch as the same appears when the switch-rails are positioned on the main-line rails, so as to cause a train traveling toward. the right on the main-line rails to take the siding. Fig. 2 is an enlarged detail transverse section taken in the plane indicated by the line 2 2 of Fig. 1 and illustrating the manner in which the inner switch rail is pivotally mounted. Fig. 2 shows the free end of the inner switch-rail. Fig. 3 is an enlarged trans verse section taken in the plane indicated by the line 3 8 of Fig. 1 and illustrating'the switch-operating mechanism. Fig. 4 is a similar view taken in the plane indicated by the line 4 4 of Fig. 1 and illustrating one of the horizontal antifriction-supports of the switch-rails. Fig. 5 is a transverse section, partly in elevation, illustrating one of the tierods through the medium of which the switchrails are fixedly connected together, so as to move as one piece. Fig. 6 is a perspective view of one of the diagonal braces interposed between and connected to the switch-rails; and Fig. 7 is a detail transverse section taken in the plane indicated by the line 7 7 of Fig. 1 looking in the direction indicated by arrow and with the switch-rails omitted, so as to better show the inclined antifrictionsupport for the said switch-rails.

Similar letters designate corresponding parts in all of the views of the drawings, referring to which A A are the rails of the main line, which may beof the ordinary or any other type compatible with the purposes of my invention, and are continuous or unbroken, as shown.

B and C are the rails of the siding or turn.- out, which may be and preferably are of the usual construction, with the exception that the rail C has a beveled end a.

D is the inner switch-rail, and E is the outer switch-rail, the switch-rail D having a beveled end b opposed to the beveled end a of the siding-rail C and the switch-rail E abutting at its heel against the siding-rail B, as shown in Fig. 1. The rear portion of the inner switch-rail D is secured at an intermediate point of its length in a chair F, Figs. 1 and 2, and the said chair is provided with a depending pin 0, which is disposed in a complementary socket d in a metallic rest or support Gr, secured to one of the sleepers or ties, whereby it will be apparent that the said switch-rail D is free to be moved laterally toward and from the main-line rails A. The heel or rear end of the switch-rail E is loosely arranged in a chair H, which also receives the end of the siding-rail B and is free to move in and out of the said chair H incident to the movements of the switch-rails toward and away from the main-line, rails. At its forward end the switch-rail E is beveled or pointed, as indicated by 0, so as to lap the inner side of one of the mainline rails A, while at its forward end the switch-rail D is provided. with a beveled overhanging extension f, designed to rest over the tread of the other main-line rail, as shown in Fig. 1. In virtue of this construction it will be apparent that a train traveling on the main line toward the right will readily pass from the main-line rails to the switch-rails and be guided by the latter to the siding or turnout rails. It will also be apparent that when the switch rails are moved in the direction indicated by arrow in Fig. l to a position o'li of the main-line rails the main line is left entirely clear of obstructions and is free from breaks or interruptions of any kind, which is an important desideratum. The switch-rails D and E are fixedly connected together, so as to move as one piece through the medium of tie-rods I and diagonal braces J. (Clearly shown in Figs. 1, 5, and 6.) The tie-rods I for the sake of economy are respectively made up of a body m of tough wood and metallic sleeves n, receiving and bolted to the ends of the body and having extensions p, connected by bolts or other suitable means to the webs of the switchrails. There are preferably two of the braces J intermediate each pair of tie-rods I, the said braces, which are in the form of metallic bars, being crossed, as shown in Fig. 1, and bolted at their ends to the webs of the switchrails. By virtue of this construction it will be seen that the switch-rails are strongly connected, so as to move together or as one piece, and at the same time the liability of either of the switch-rails spreading is precluded.

K and L are transversely-arranged antifriction-supports on which the inner switch- I'ail D is arranged and adapted to move. In the preferred embodiment of my invention the said antifriction-supports are horizontal and are respectively made up of a body 8, embedded in and fixed to one of the sleepers or ties, and lapped wheels 15, mounted in and projecting above the body, so as to present a rolling surface to the base of the said switchrail D. The outer switch-rail D rests when the switch-rails are entirely off of the mainline rails in a horizontal plane immediately above that of the treads of the said main-line rails, and in order to assure the point of the switch-rail E moving down to the same plane as the main-line rails when the switch-rails are thrown into their working position I provide the inclined antifriction support M. (Shown in Figs. 1 and 7.) The said support M, like the supports K and L, comprises a body and lapped wheels mounted in and projecting above the body; but the said wheels are arranged in an inclined plane for the purpose stated.

N N are abutments mounted between the rails of the main line in position to engage and support the base of the switch-rail E when the latter is in the position shown in Fig. 1 ,and P is the switch-operating mechanism as a whole, the said mechanism being shown in Figs. 1 and 3. In the present and preferred embodiment of my invention the switch operating mechanism comprises a rack-bar o, pivotally connected at w to the switch-rail I) and movable over an antifriction supporting-roller w, a shaft y journaled in suitab e fixed bearings and carrying spurgears a and b, the former of which is intermeshed withthe rack-bar o, a stand 0, a vertical shaft d, carrying a gear 6 and designed to be equipped with a target or a signal-lamp, (not shown,) a spur-gear f, mounted on the stand 0 and intermeshed with the spur-gear b and having a circular series of teeth g in its side intermeshed with the gear 6 and also having a crank h, Fig. 1, a locking-lever 7c, and a keeper Z, to which the locking-lever is secured,as will be presently described. The

, embodiment.

locking-lever 7c is provided on one of its arms with a toothed portion 1), and when the said toothed portion 1) is engaged with the spurgear b and the lever is secured on the keeper Z by the hasp r and lock 8 it will be apparent that there is no liability of the switchrails being moved by a mischievous or careless person. 'When, however, the lockinglever k is released and moved out of engage ment with the spur-gear b, rotation of the spur-gear f will obviously efiect movement of the switch-rail on or off the main-line rail according to the direction in which the said spur-gear is turned through the medium of its crank h. It will also be apparent that movement of the switch-rails will be attended by turning of the shaft (1 so as to properly position the target to show the position of the switch-rails relative to the main-line rails.

It will be gathered from the foregoing that when the switch-rails are in their idle position the rails of the main line are continuous and free from obstruction of any kind, and it will also be gathered that when the switchrails are in their working position a train may smoothly pass from the main line to the siding or turnout. It will further be gathered that my improvements as a whole are well adapted to withstand the rough usage to which railway-track appliances are ordinarily subjected, and. hence there is little liability of any of the parts becoming derangedwhile in use.

In practice the inside switch-rail f will preferably be made to extend about three feet six inches aheadof the switch-rail e, this in order to assure a wheel on a car having passed across the adjacent main-line rail A when it reaches a point opposite the end of the switchrail e.

When desirable, the bodies m of the tierods I may be made of iron and may be con nected to the sleeves n through the medium of bolts and jam-nuts, the latter being, by preference, arranged below the sleeves.

I have entered into a detailed description of the construction and relative arrangement of the parts embraced in the present and preferred embodiment of my invention in order to impart a definite understanding of the said I do not desire, however, to be understood as confining myself to the said specific construction and relative arrangement of parts, as such changes or modifications may be made in practice as fairly fall within the scope of my claimed invention.
