RAILROAD-CROSSING.

Specification of Letters Patent.

Patented Dec. 4, 1906.

Application filed January 15,1906. Serial No- 296.026.

may be easily applied to a crossing as ordinarily constructed without making any changes in its construction or cutting away any of its parts.

A further object of the invention is to provide means for inserting a solid block into the groove or space between the rails in such a manner that it will be firmly supported and to provide means for looking the block in position against possible displacement and so as to minimize the liability of breakage.

It is also an object of the invention to provide means whereby the device will be locked against operation and the operator thus notified should a part become broken or the space between the rails become filled with dirt, snow, or ice and to also provide a very simple and efficient device which may be quickly attached to the ordinary crossing, all as hereinafter more fully described, refer ence being had .to the accompanying drawings, in which- Figure 1 is a diagrammatic plan view of a crossing with the invention applied thereto Fig. 2, an enlarged view of one corner of the same; Fig. 3, an Ienlarged view of Fig. 2 with parts broken away to show the construction; Fig. 4, a transverse vertical section of Fig. 3, and Fig. 5 a detail showing the manner in which the locking-dogs are unlocked.

A A are the main or stock rails of one track, and A A are those of the other track, which cross the former at an angle of less than ninety degrees, forming therewith an obtuse angle at one side of each rail and an acute angle at the opposite side.

B represents the reinforcing-rails, C the guard-rails, and D the fillers between the stock and guard rails, all constructed and arranged in the ordinary manner.

Supported within the obtuse angle at each corner of the crossing is mechanism for operating suitable blocks 1, adapted to fit in the groove or space between the guard and main rails, and thus form a continuousbearing-surface for the car-wheels. When the track is open for traflic in the direction of the arrows in Fig. 1, the blocks adapted to be inserted in the groove between rails A and their guardrails are in operative position, and the other set of blocks is swung to a position outside of and away from the rails. The mechanisms for moving the blocks are all the same, except that the mechanism in each of the two angles formed by the outer sides of the main rails is provided with a double arm and two blocks, one for each track, while the others have single arms and but one block, all being adapted to operate in a ninety-degree angle.

As shown in Figs. 2, 3, and 4, 1 1 are the contact-blocks adapted to fit in the groove or space between the main and guard rails and rest upon the filler-block D, which forms the support therefor when engaged by a carwheel. These blocks are carried over the main rails and lowered into the grooves by arms 2, to the outer ends of which said blocks are secured, and these arms are secured to a vertical shaft 3, mounted in bearings in a suitable casing 4, which is supported upon brackets 5, secured to the outer sides of the reinforcing-rails by the same bolts which pass through the rails and fish-plates to secure the same together.

Each block when in o erative position within the space between t e rails is securely locked therein by a lon itudinally-movable rod 6, projecting through an opening in the forward end of the casing into a hole drilled through the rails and engages a hole in the block, a rod being provided for each block. These rods are pivotally attached at their inner ends to the ends of a rocker-bar 7, secured to the upper end of a vertical pin 8 rotatable in bearings in the top and bottom of the casing, the lower end of said pin projecting through the bottom of the casing and being provided with an operating-lever 9, to which may be attached in the usual manner a rod leading to the interlocking mechanism or to any other safety device the crossing is to be interlocked with.

The shaft 3 is raised vertically to lift the block 1 out of the groove or space'between the rails after the rod has been retracted to release said block by a lever 10, having a forked end engaging a groove in the shaft and pivoted intermediate its ends upon a horizontal shaft 11, mounted in bearings in the rear part of the casing. A horizontal camdisk 12 is provided with a stub-shaft 13..to engage a suitable bearing in the bottom of the casing and is thus pivoted with its axis vertically below the shaft 11 and rear end of the lever 10 which lever is provided with rolls 14 to engage cam projections 15 on the upper face of the disk. On the lower and outer end of the stub-shaft 13 is secured an operating-lever 16, by means of which the disk is turned, an operating-rod being attached to said lever and to any suitable operating device situated some distance away.

After the arm 2 has been lifted to raise the 'block it is turned from over the rail by rotating the vertical shaft 3, said shaft being provided with a s uared lower end 17, engaging a square axial ole in a pinion 18 and its downwardly-extending shank portion, which portion is journaled in a suitable bearing in the bottom of the casing. The shank is free to rotate in said bearing, but is prevented from being lifted therefrom by a set-screw 19,

tapped through the bearing and engaging a tween the rails be broken oif or the slot be-.

tween the other rails become clogged in such a way as to prevent the other block from entering or being forced to its seat on the filler, gravity-dogs 23, mounted upon the shaft 11, are provided to engage and prevent the full operation of the locking-rods 6. At the rear side of the shaft these dogs are provided with enlarged ends and at their forward ends are provided with laterally-projecting pins 24, extending outward through slots in the sides of the casing, the enlarged or weighted ends operating by gravity to normally hold the dogs tilted with the pins in the upper ends of the slots. When sald dogs are so tilted, their forward ends lie in the path of the rocker-bar 7, so that when said bar is turned to retract one of the locking-rods it will engage said dog when in its mid-position and be prevented from further operation until said dog is depressed out of its path. To so depress the dog, the block 1 is formed with a downwardlyextending end portion 25, as shown in Fig. 5, which whenthe arm is swungbackward over the casing and thenlowered will engage the pin 24 and depress the dog.

The parts being in the position shown in Fig. 3 and the operator wishing to clear track A and close track A, he will first move lever 9 to turn the rocker-bar until it engages the dog at that side, thus retracting the locking-rod and releasing the block and at the same time projecting the other rod a short distance, so that its end of the rocker will be moved from over its locking-dog. The lever 16 is then operated to turn the disk 12, the cam upon the forward side of which is in such a position that it will at once engage and rock the forked lever, lifting its forward end and raising the shaft 3 with its attached supporting-arms and the contact-blocks. This lifting of the blocks releases the dog which was depressed by the block lying over the casing, and thus the locking-rods are prevented from operation in either direction until one of said dogs is again depressed. Any accidental operation of lever 9 is therefore prevented until one of the contact-blocks is in place to receive the end of the rod, and its operation in the wrong direction is also prevented.

When the arm has been fully lifted by the forward cam, it is held in that position during the further turning of the disk, which brings the stud 22 into engagement with the escapement-lever and turns the same until the forwardly-projecting arm is swung back, bringing its block directly over the pin on the locking-dog at that side, and the arm proj ecting in the opposite direction is swung forward, bringingits block in position over the space between the rails. The forward cam then runs out of contact with the lever, and the rear cam engages the rear end of said lever, thus rocking the lever and lowering the block at one side into contact with the dog to depress said dog out of the path of the rockerbar 7 and forcing the other block downward between the rails. The block being thus placed in position between rail A and its guard-rail and the dog at the opposite side of the casing depressed, the lever 9 is then turned to further retract the locking-rod at one side and project the locking-rod at the opposite side through its block, which is thus firmly held in place, closing the track formed by the rails A.

Should one of the contact-blocks become broken, it will not depress its dog when swung back over the casing, and the turning of the rocker-bar beyond its mid-position will be prevented, thus indicating to the operator that the device is out of order, and if the lowering of, the block is prevented by dirt or other obstruction in the slot between the rails the dog will not be operated by the other block, and the operator will thus be notified of the fact by reason of being unable to engsligek the locking-rod with the apertured Having thus fully described my invention, what I claim is 1.
