To all whom it may concern:

Be it known that I, JOHN E. REESE, a citizen of the United States, residing at Louisville, in the county of Jefferson and State of Kentucky, have invented a certain new and useful Railroad-Crossing, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to railroad crossings and the object of the invention is to provide in connection with fixed main and crossing rails, intervening rail sections movable in such manner and by such means that the said sections are adapted to be shifted into and out of position and when in position the said movable sections form continuations or extensions of the main or crossing rails as the case may be, thus giving a practically continuous or unbrokentrack.

The invention has special reference to the shiftable rail section, the manner of mounting, guiding and shifting the same and the operating connections whereby the movement of the sections is primarily effected.

With the above and other objects in view, the nature of which will more fully appear as the description proceeds, the invention consists in the novel construction, combination and arrangement of parts herein fully described, illustrated and claimed.

In the accompanying drawings :Figure 1 is a plan view of the railroad crossing of this invention, showing the movable sections of one track in position and those of the other track shifted out of position. Fig. 2 is a cross section on an enlarged scale, taken on the line 22 of Fig. 1. Fig. 3 is a cross section on the line 33 of Fig. 1. Fig. 4 is a cross section on the line 44 of Fig. 1. Fig. 5 is a cross section on the line 5-5 of Fig. 1. Fig. 6 is a cross section on the line 6-6 of Fig. 1, illustrating the locking device. Fig. 7 1s a side elevation of the locking device, showing portions of the adjacent rail and foundation base. Fig. 8 is a plan view showing the locking device. Fig. 9 is a cross section on the line 99 of Fig. 8.

Referring to the drawings 1, 1, designate the main track rails and 2, 2, the crossing rails, or vice versa, the said rails having their ends beveled as shown at 3, the bevel of the extremity of one rail forming practically a continuation of the bevel of the rail adjacent thereto and also at right angles thereto. The main and crossing track rails 1 and 2 are supported by a suitable foundation consisting preferably of I-beams 4, which extend under all of said rails and also beneath the intervening movable rail sections hereinafter particularly described. In connection with each rail 1 and 2, I employ a movable rail section which intervenes between the fixed parts of the rail ofwhich it forms an extension or continuation, and said rail section embodies end to end separable members 5 and 6, the member 5 being movable lengthwise and also laterally and the member 6 being movable lengthwise, whereby the'beveled extremities 7 and 8 of the members 5 and 6 are adapted to be moved away from and toward the correspondingly beveled extremities of the fixed rails, Fig. 1 illustrating two of the movable sections in position and the remaining two sections out of position, the operating mechanism for shifting the movable sections being so arranged that wh en one set of rail sections is moved into position for a train to pass along the track, the other movable rail sections are moved out of position, and vice versa. In order to accomplish the shifting above referred to, the member 5 of each movable rail section is mounted on and carried by a rail shifting lever 9 pivoted at 10, at one end, to the base or foundation referred to, the opposite end of said lever being free to swing. The rail member 5 is mounted to slide endwise upon the lever 9 and is actuated by means of a slide rod 11, one end of which is fastened, as at 12 to the outside of the member 5, while the opposite end of said slide rod is bent downward to form a guide pin 13 which works in a slot extending lengthwise of the lever 9, said slot being shown at 14.

Located underthe swinging end of the lever 9 is a fixed guide plate 15 having an angular slot 16 into which the guide pin 13 fits and along which it slides as the lever 9 swings inward and outward when acted upon by the mechanism hereinafter described. By reason of the angularity of the slot 16, as the leveri9 is moved outward and inward, the rail member 5 is shifted endwise along the lever, being at the same time moved laterally by the lever. In this way the member is thrown into and out of alinement with the corresponding fixed rail ends and also slid toward and away from the end of the contiguous fixed rail, as clearly illustrated in Fig. l. The other complemental rail member 6 is mounted to slide endwise only, suitable guides being provided to permit such movement while preventing lateral movement thereof. In order to slide the member 6, it is provided with a laterally extending plate 17 which is fast thereon and provided with an angular guide slot 18 whic h receives a projection or runner 19 extending downward from the bottom of the lever 9, as shown in Fig. 3, the said runner preferably embodying an antifriction roller which works easily along said slot 18, the base or foundation being also cut away as shown at 20 to admit of such movement of the runner or projection. It will now be understood that as the lever 9 is moved outward and inward to shift the member 5, the runner 19 acts on the extension plate 17 to shift the member 6 endwise, thereby moving the beveled extremity 8 thereof toward and away from the corresponding beveled extremity of the adjoining fixed rail. It will thus be seen that the rail section members are operatively connected or coupled together so that when the rail shifting lever is moved in either direction to shift the memher 5, the other member 6 is simultaneously shifted, one member being shifted endwise only, and the other member being shifted both endwise and laterally.

The mechanism for shifting the movable rail sections is shown as consisting of two sets of toggle levers connected for simultaneous joint operation by a common pivot 21. To operate said toggle levers, I employ a push rod 22 and a pull rod 23, the said rods operating alternately with a push and a pull. When the rod 22 .is pushed inward, it rocks a bell crank lever 24, which pushes on a connecting rod 25; the latter in turn rocks an elbow lever 26 and the latter, through a connecting link 27 pushes inward on one member 28 of one set of toggle levers, the other toggle lever member 29 of that set being connected by a coupling pin 30 to the lever 9 and acting in the movement just described to swing the lever 9 outward to shift the rail section members out of position, as above described. In the reverse movement of the actuating connections just described, the lever 9 is drawn inward and the members 5 and 6 are restored to their operative positions in readiness for a train to pass over them. The rod 23 acts on the other set of movable rail sections, as follows; when the rod 23 is pulled, it rocks an elbow lever 31 which pulls on a link 32 and vibrates one member 33 of the other set of toggle levers, the other member 34 of said set being connected to its respective lever 9 by a coupling pin 35, similar to that 30, above referred to. The two sets of toggle levers are thus connected by a common pivot and one set acts as a fulcrum for the other set.

In connection with each lever 9, I employ locking mechanism consisting of a locking device in the form of a rocking cam 36 pivotally mounted on the base at the outer side and comprising a lever arm 37 from which an operating rod 38 extends lengthwise of the rail for a suitable distance Where it is bent and passed transversely under the rail and through the base or foundation, connecting on the opposite side with an actuating rod 39, the projecting end 40 of which is movable into and out of a hole 41 in a latch rod or bar 42, which is connected by means of a bracket 43 to the lever 9. When the lever is swung inward, the cam is thrown up behind said lever and having an inclined inner face, it binds against said lever and locks it in position thus holding the rail sections members securely against lateral displacement. At the same time the end 40 enters the hole 41 and serves as an additional safeguard against the accidental movement of the rail section members.

I claim 1. In a railroad crossing, the combination with fixed main and crossing rails, of intervening movable sections having a scarf-jointed abutment with the ends of the fixed main and crossing rails, each intervening section embodying overlapping members, and a single operating device and connections adapted to simultaneously separate the ends of the intervening section members from the corresponding ends of the fixed main and crossing rails.
