BAILWAY-SlVITCH FILLER.

iaise-2.

Specification of Letters Patent.

Patented July 4, 1922.

T 0 all whom it may concern:

Be it known that I, DENNIS Lariat, citizen of the United States, residing at Louisville. in the county of Jefferson and State of Kentucky, have invented certain new and useful Improvements in Railway- Switch. Fillers of which the following is specification, reference being had therein to theaccompanying drawing.

This invention relates to improvements in railway switches and more particularly to the protection of split switches.

The primary object of the invention is to provide an inexpensive and etlicient guard for preventing chains or other parts hanging from a passing train from catching. under the head of the switch rail and stock rail at their junction, and thereby spreading the switch point and endangering a train approaching from the opposite direction.

A further object of the invention is to provide a filler between the switch point and stock rail designed to prevent the heel of the'shoe of a switch-man or other work-man from being caught between the stock and switch rails.

With the foregoing objects outlined, and with other objects in view which will ap pear as the description proceeds, the invention consists in the novel features hereinafter described in detail. illustrated in the accompanying drawing and more particularly pointed out in the appended claims.

Referring to the drawing:

Figure 1 is a top plan view of a portion of a track showing one or. the stock rails and one of the switch points.

Fig. 2 is a perspective view of a hearing or. filler plate adapted to be secured to the stock rail beneath the head of the same.

Fig. 3 is a perspective view of a special form of filler block designed to be connected to the switch point.

4 is a longitudinal sectional view of the switch point filler and showing the same arranged alongside of the stock rail.

Fig. 5 is a transverse vertical sectional view taken on line 55 of Fig. 4.

Fig. dis a similar view taken on line 66 of Fig. 4.

Fig. 7 is a similar View taken on line 7 7 of Fig. 4.

The device consists essentially of two steel castings, one connected to the stock rail and one to the switch point, the latter being movable with the switch point.

In the following detail description, 1 d esignates a stock rail and 2 a switch point cooperating therewith. The switch point carwas a wedge shaped filler blocl: 3 provided with apertures 41- adapted to receive bolts 8 employed in securing the filler block to the web of the switch point. As best shown in Fig. 6, the heads of the bolts 8 are countersunk in the outer face of the filler block so that no projecting parts will be formed by the securing means. The filler block is provided at one end with a grooved inclined ramp 13 and the upper surface of said block is grooved and inclined upwardly from said ramp as shown at '7 to the end 10' of the block. it will be noted that the end 10 is rounded so as to l ave no corner on which any dragging part mightcatch, and in practice this rounded end willfit under the head of the stock rail.

A bearing or filler block 5 having inclined ends 12 is secured to the web of the stock rail by means of bolts 9 which extend through holes 6 in the block. The heads of the bolts 9 are countersunk in the block as shown in Figs. 5 6 and 7. The inclined ends 12 of the block 5 also function to prevent dragging parts from catching, and as a matter of fact these surfaces facilitate the passage of dragging parts over the portion of the track where the switch points are arranged.

The block 5 is provided at one end with a recessed portion 11 which is adapted to receive the point 10 of the block 8 so that an even fit will be provided bet-ween the filler blocks and the point 10 will be permitted to pass under the head of the stock rail.

The filler blocks 3 and 5 are preferably cast and the block 3 is made very heavy and strong at the open end, where it receives the impact or blow from a dragging object. After the object travels along the groove 7 and is brought to the level of the bottom of the rail heads, there is little stress, and consequently the casting may be reduced in thickness at the pointand as a matter of fact may be made very light.

The blocks 3 and 5 preferably extend from near the heel of the switch to the junction of the head of the switch point with the stock rail.

From the foregoing, I believe that the construction, operation and advantages of the invention may be readily understood by being attached to and movable with the switch point.

2. A combination as claimed in claim 1 in which the filler block has its upper surface gradually inclined upwardly from the wide end of the block towards its point.

,3. A combination as claimed in claim 1 in which the filler block has its upper surface graduallyinclined upwardly from the wide end of the block towards its point, and in which the upper surface of the block is provided with a longitudinal groove.

4:. A combination as defined in claim 1 in which said filler block has its upper surface gradually inclined upwardly from its wide end to its point, and the upper surface of said block is provided with a longitudinally extending groove.

5. A combination as claimed in claim 1 in which the filler block is secured tothe switch point by means of bolts having headscountersunk in the filler block.

6. The combination with a stock rail and a switch point cooperating therewith, of a bearing block secured to the stock railand having beveled ends, said block being also provided near one end with a side recess, bolts securing said block to the web of the stock rail and provided with heads countersunk in'said block, a wedge-shaped filler block fixed to said switch point and having its upper surface gradually inclined up wardly from the wide end of'the block to its point, the upper surface of the wedgeshaped block being provided with a longitudinally extending groove and the point of said wedge-shaped block being adapted to pass into the recess formed in the first mentioned block, and fastening. means securing the wedge-shaped block to said switch point.

In testimony whereof I hereunto affix my signature in the presence of two witnesses.
