This invention relates to certain new and useful improvements in mine rail ties and rail anchors.

The primary object of the invention is to provide car track structures for mines and has particular reference to the tie construction and devices for anchoring rails thereon.

A further object of the invention is to provide a mine rail tie and rail anchor wherein each rail supported on the metallic tie has the base flange thereof at one side engaged by a clamp rigid with the tie with the other rail flange engaged by a pair of pivotally mounted clamps that are adapted to be locked in their rail-engaging position.

A further object of the invention is to provide a mine rail tie and rail anchor of the foregoing character with means carried by the tie adjacent each rail seat for forcing the rail into engagement with rigid clamps carried by the tie and aiding for the proper feeding of the rail to the base flange thereof in proximity of the tie seat to be bent or distorted and further to position the spaced flange of the rail for engagement by pivotally mounted clamps carried by the tie.

With the above and other objects in view that will become apparent as the nature of the invention is better understood, the same consists in the novel form, combination and arrangement of parts hereinafter more fully described, shown in the accompanying drawings and claimed.

Referring more in detail to the accompanying drawings, the reference numeral [0 designates in general a metallic tie for mine rails, the tie being of inverted U-shaped construction, comprising a top wall H and side walls l2. The 1 rails I3 supported on the top wall ll of the tie are spaced at the proper mine gage with one of the rails positioned adjacent one end of the tie and in proximity of a side wall of the mine passage to give better access to the devices for 20 anchoring the rails on the ties.

Each rail l3 comprises base flanges l4 and I5, the base flange M being engaged by a clamp l6 rigid with the top wall of the tie Ill, the other flanges l5 of the rails being engaged by pivotally 25 mounted clamps. A rod ll extends transversely of the tie It beneath the top wall I l thereof and projects through the side walls I2, the rod l1 carrying a head E8 on one end thereof engaged with the adjacent side wall l2 as shown in Figure 5, while the other threaded projecting end thereof receives a lock nut 19, the rod I! being positioned laterally of the base flange l5 of the rails l3. A pair of clamps 20 is pivotally mounted upon the rod [1 and projects upwardly through the opening 2| in the top wall ll of the tie, each clamp 20 carrying a clamping arm 22 adapted to be engaged with the base flange l5 of the rail l3 while a foot 23 projects laterally of the clamp 20, substantially in the plane of the clamping arm 22 and above the rod I1, the openings 2i in the top wall ll of the tie being of a size to permit free movement therethrough of the foot 23 of the clamp 20.

A locking device is associated with the clamps 20 for holding the clamping arms 22 engaged with the base flanges of the rails and include a latch plate 24 slidably mounted longitudinally of the tie between the top wall ll thereof and in engagement with the lower face of said top wall, the latch plate being supported upon the cross rod 25 extending between the side walls l2 of the tie. The end of the latch plate 24 adjacent the clamp 20 is adapted to underlie the foot 23 of the clamp to hold the clamp against piv- 5 otal movement with the clamping arms 22 there'- of engaged with the base flanges I5 of the rail, the operating means for the sliding latch plate 24 for moving the same into and out of operative positions relative to the clamp foot 23 comprising an arm 26 struck out and upwardly therefrom at the end spaced from the clamp foot 23 with the arm projecting upwardly through the opening 21 in the top wall II of the tie, the

upper end of the arm 26 carrying a depending flange 28. A lock device for the latch plate 24 comprises a lever 29 pivotally mounted as at 30 upon the upper side of the top wall II of the tie, one end of the lever 29 carrying a hook 3| adapted to be engaged beneath the flange 28 of the arm 26 with an operating handle 32 at the other end of the lever 29. With the lever 29 engaged with the arm 26 and flange 28 of the latch plate 24 as shown in Figure 4, the forward end of the latch plate is disposed beneath the foot 23 of the clamp 20 for holding the clamping arm 22 in engagement with the base flange of the rail. When the lever 29. is moved on its pivotal mounting 30 to displace the hook 3I laterally of the arm 26 and flange 28 of the latch plate, the latter is permitted to slide upon the guide supporting rod 25 to be disengaged from and positioned laterally of the clamp foot 23 to permit pivotal movement of the clamp 20.

In assembling the rails I3 on the tie I9, the base flange I4 of the rail is first engaged with the rigid clamp i6 and the clamps 29 that were moved to the dotted line position as shown in Figure 4 are then shifted to the full line positions illustrated and locked in position by the latch plate 24. Should difiiculty be encountered in seating the rails on the tie, due to distortion or bent portions of the rail flanges, means is provided for forcing the rail into proper seating position on the tie III and as shown in Figures 1 to 3 include such a device for each rail seat having an arm 33 pivotally supported at the lower end thereof as at 34 upon the outer side of aside wall I 2 of the tie adjacent its lower end, the upper end of the arm 33 having r a lever 35 pivotally mounted thereon as at 35, a

' nose 3! carried by one end of the lever 35 being disposed for engagement with the rail I3, while the other end of the lever 35 has a screw bolt 38 threaded therethrough that has the lower end thereof engaged with the top wall II of the tie. Upon downward movement of the screw 38 through the lever 35, the nose 3'! of the lever is forced into engagement with the rail I3 for moving the same onto its seat on the tie and into position to be engaged by the rigid clamps I6.

A webbing arrangement 39 depends from the underside of the top wall in which earth may be packed to aid in holding the tie in position.

A modified form of locking lever for the latch plate 24 is shown in Figure 7, the handle 32a of the latch plate 23a having a rod 40 depending downwardly therethrough with an angular hand grip 4| upon its upper end, the rod 49, carrying a disk 42 adjacent its lower end with a coil spring 43 surrounding the rod between the handle 32a and disk 42 for normally forcing the rod 49 in a downward direction, the lower end of the rod 40 below the disk 42 being receivable in a depression 44 formed in the upper wall I I of the tie for holding the lever 29a in its locked position relative to the sliding latch plate 24.

In lieu of the cross rods 25 for the support of the sliding latch plate 24, the modified construction shown in Figure 8 may be provided and in which the top wall IIa with a longitudinally extending groove 25a in the inner face of each side wall I2a adjacent the bottom face of the top wall I I a and into which groove 25a the side edges of the latch plate 24a are slidably mounted for guiding movements therein.

From the above detailed description of the invention, it is believed that the construction and operation thereof will at once be apparent and while there are herein shown and described the preferred embodiment of the invention, it is nevertheless to be understood that minor changes may be made therein without departing from the spirit and scope of the invention as claimed.
