RAILWAY.

SPECIFICATION forming part of Letters Patent No. 436,589, dated September 16, 1890.

Application filed October 16, 1889. Serial No.327,208. (N0 model.)

To all whom it may concern:

Be it known that LGEORGE W. STONE, Jr., of Waukesha, in the county of Vvaukesha, and in the State of Wisconsin, have invented certain new and useful Improvements in Railways; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to pivotal rails which are located at the juncture of the convergent rails of a main track and a branch tracksuch as a spur, a siding, &c.-and which pivotal rails operate, in lieu of a frog, to guide the wheels properly upon the main or branch track, as desired; and my invention consists in certain peculiar and novel features of construction and arrangement, as hereinafter described, and pointed out in the appended claim.

In the drawings, Figure 1 is a plan view of the junction of a main and a branch track with my improvements applied thereto. Fig. 2 is a view, partly in side elevation and partly in vertical longitudinal section, of the pivoted rail and certain of its connections. Fig. Sis a detached view, in side elevation, of aswitchstand, with a portion of the rod which connects the switch-lever with the operating mechanism of the pivotal rail.

The object of my invention is to improve the construction and arrangement of the operative mechanism between the pivoted rail and the switch, so that more powerful and direct action upon the pivoted rails and the split-switch rails results from the operation of the switch-lever than has been possible previous to my invention This result I accomplish by virtue of the construction which I will now proceed to explain Referring to the drawings, A A designate the rails of the main line, and B B the rails of the branch line.

C designates the rails of a split switch, which at their convergent ends coincide with the convergent ends of the adjacent rails of the main and branch tracks A B, and the divergent ends of which are movable so as to come into close engagement with the outer rail of the branch track or the opposite rail of the main track, as required.

N designates a switch-lever stand, which is located adjacent to the divergent ends of the split-switch rails C, and M designates the vertical rod, which has bearings in the stand M,

and the upper end of which carries an operatinglever, either of the precise form shown or of any other suitable form. The lower end of this switch-rod is formed with a crank-section, which is connected by a link 0 with the strap which unites the divergent ends of the switch-rails, and is also connected by a link L with the outer end of a T-shaped lever J K, the connection of said link being with the outer end of the arm K of said T-shaped lever. The opposite ends of the cross-arm J of the T-lever are pivotally connected by links I I with the opposite end portions of the pivoted rail D, which is provided with a central pivotbolt E. This bolt passes also through a bearing-plate F, which rests upon the adjacent ties or sleepers, and a washer-plate Q is interposed between the nut R of. said pivot-bolt and the under side of the bearing-plate I The washer Q is provided on its upper side with a circular boss P, which enters a corre sponding opening in the bearing-plate F. Near its ends the pivot-rail D is provided with bolts II, which extend downwardly and work in segmental slots G, formed in the bearingplate F. These bolts serve as stops which limit the throw of the pivot-rail, and also as the means for attaching the links I I to said pivot-rail. From this description it will be seen that the operation of the pivot-rail is rapid and effective and that its movement is limited by the same devices which connect it with the T-1ever. It will furthermore be seen that the operative connections between the switch-rod and the divergent ends of the splitswitch rails, and also the pivot-rail, all move in a horizontal plane and operate directly, powerfully, and in unison by a simple axial movement of said rod.

What I claim is The combination, with a main track, a branch track, and movable split-switch rails, of a bearing-plate located at the junction of the adjacent rails of said tracks and having slotted end portions, a pivot-rail centrally attached to said bearing-plate by a pivot-bolt and having at its ends stop-bolts working in said slots, a washer surrounding the pivot-bolt beneath the bearing-plate and having a boss to enter said plate, a T-lever located adjacent to said junction, links connecting the ends of the cross-arms of saidlever with the said stop- In testimony that I claim the foregoing I :0 bolts, a Vertical switch-rod located adjacent have hereunto set my hand, at 'Waukesha, in

to the divergent ends of the split-switch rails the county of Waukesha and State of Wisand having a crank-section at its lower end, cousin, in the presence of two witnesses.

a link connecting said crank-section With the outer arm of the T-1ever,'and a second link GEORGE W. STONE, JR. connecting said crank-section With the strap Witnesses:
