STO CK-RAIL.

Specification of Letters Patent.

Patented Apr. 4, 1916.

Application filed September 8, 1914 Serial No. 860,625.

To all whom it may concern:

Be it known that we, BENJAMIN Sams- BURY I'Vooos and SAMUEL LEWIS, both of the town of Transcona, in the Province of Manitoba, Canada, have invented certain new and useful Improvements in Stocktails, of which the following is the specification.

The invention relates to improvements in stock rails especially stock rails used on railways at switches and the object of the invention is to provide an improved form of stock rail which will receive and protect the advanced end of the switch rail thereby preventing the switch point from becoming damaged, broken or otherwise injured by the constant passage of trains as invariably occurs under present conditions.

I'Vith the above object in view the invention consists essentially in the arrangement and construction of parts hereinafter more particularly described and later pointed out in the appended claim, reference being had to the accompanying drawing in which- Figure 1 represents a plan View of a portion of a main line and the switch track with our invention applied. Fig. 2 represents a horizontal sectional view through the track, the section being taken in the plane denoted by the line XX Fig. 1. Fig. 3 represents an enlarged detailed face view of a portion of the stock rail. Fig. t represents an enlarged detailed vertical sectional view through the stock rail and switch rail, the section being taken in the plane denoted by the line YY Fig. 2. Fig. 5 represents an enlarged detailed vertical sectional view through the stock rail and switch rail, the section being taken in the plane denoted by the line Z-Z Fig. 2. Fig. 6 represents an enlarged detailed vertical sectional view through the stock rail and switch rail, the section being taken in the plane denoted by the line T-T Fig. 2. Fig. 7 represents an enlarged detailed vertical sectional view through the stock rail and switch rail, the section being taken in the plane denoted bv the line P-P Fig. 2.

In the drawing like characters of reference indicate corresponding parts in each figure. V

1 and 2 represent stock rails mounted in the usual way on the ties or sleepers 3 to which they are secured permanently by the customary spikes 4. I

5 and 6 represent switch rails of ordinary construction having their advancing ends shiftably mounted on the ties and connected to each otherby tie bars 7 and 8, the arrangement being such that by the manipulation of the arm 9 associated with the bar 7, the advancing ends of the switch rails can be shifted in respect to the main line rails to effect the passage of the train through on the main line or onto the switch track as wished.

Our invention relates in no way to the construction or manipulation of the switch rails or in the manner in which they are shifted, residing wholly in the construction of the stock rail.

According to our invention the head of the stock rail is cut or channeled on the switch rail side as indicated at 10 in a special manner to receive the advancing end of the switch rail. Immediately opposite the forward or advancing end of the switch rail, the channel cut in the head is deepest as shown in Fig. 4 the depth of the channel being sufficient to receive wholly the forward end of the switch rail when the said switch rail is thrown over against-the stock rail. At this particular point it is also to be noticed that the channel so cut in the stock rail provides an overhanging portion 11 which completely covers the advanced end of the switch rail. The channel formed in the head of the stock rail gradually de creases in depth and increases in width from the point wherein the section shown in Fig. 4 is taken. to the point where the section shown in Fig. 7 appears. at which latter point the channel entirely disappears, the rail having at this latter location its natural contour. In actual practice the distance between these two points may be possibly eighteen inches or, in other words, it is equal to the distance which is customarily understood as the length of the switch rail point. e might here remark that the advance end of the switch rail tapers both at the sides and at the top, having the greater cross sectional area at some distance back from the point and gradually tapering and decreasing in cross sectional area from this larger section to the front end.

According to our invention, as obvious from the description hereinbefore given, the stock rail is simply cut to accommodate a portion of the forward or advanced end 0)": the switch rail as it will be seen from observing the various sections appearing in Figs. 4, 5, 6 and 7 of the drawing that in Fig. 4c the channel in the head receives fully the forward end of the switch rail while in the other sectional views the switch rail is gradually increasing in cross section while the channel is gradually decreasing in depth and increasing in width.

lVith a stock rail of the above nature inserted at a switch the hammering of the wheels of a passing train on the switch rail point is minimized to a marked extent as it will be seen the point of the switch rail is fully covered by the head of the stock rail at the point where the wheels are directed on the switch rail.

l/Vhat we claim as our invention is;-

In combination, a stock rail having'the Signed at Winnipeg, this 8th day of,
