OLIVER JosnrH KINc, or HAMLET or WINTER, SASKATCHEWAN, GANAIDiA;

RAILWAY CROSSING.

Application filed November 17, 1926. Serial No. 148,874.

This invention relates to railroad crossings in which a plurality of planks are laid longitudinally upon the ties between the rails for the purpose of providing a level crossing surface. I These planks when so positioned extend above thenormal level of the roadbed and consequently are a source of constant danger to the railway and other vehicular vtraflio because they are apt to bestruck and displaced by dragging parts on passing rolling stock.

In fact many serious accidents resulting from this cause have occurred in the past with, in some instances, loss of life.

The object of the present invention is to reduce the danger of accidental displacement of these planks to a minimum by providing means which will cause any parts hanging abnormally low on passing rolling stock to ride upwardly over the crossing without disturbing it in any way, andwhioh will at the Same time serve to anchor the,

crossing planks to the ties.

i To this end my invention consists of the combination, construction and particular arrangement of the parts hereinafter described and illustrated and pointed out in the claim.

A practical embodiment of the invention is represented in the accompanying draw ings in which similar reference characters indicate the same parts in all the views."

Referring to these drawings:

Figure 1 is a plan view of a railway crossing constructed according to my invention; 1 Figure 2 is a sectional view taken on line 22 Figure 1;

Figure 3 is a detail perspective view of one of the crossing plank plates; and

.Figure 4 is a transverse sectional view taken on line 44; Figure 8.

In the accompanying drawings the track rails are indicated at 2, the ties at 3, the crossing planks at V4, and the means for anchoring the planks and preventing their displacement at 5. s

The planks are disposed longitudinally upon the ties between the rails and their top surfaces unitedly present a crossing surface that is substantially level with the heads of the rails as indicated in Figure 2. It is obvious that they, extend a sufficient distance above the normal level of the roadbed to constitute a serious obstruction to dragging plank plates is employed at each endof the group. Each of these plates is constituted by a unitary metallic member comprising a flat horizontally disposed plank engaging portion 6, an inclined guard v or deflector portion 7' of inverted channel cross-section having vertically disposed side portions 9 and 10 respectively, and a tie-engaging .portion 8. In the present embodiment in which a. single plate is used to cover all the plank ends each plate is made of suflicient length to extend from one rail to within close proximity of the other, and its width is such that when mounted in position its inclined ortion will present a gentle incline rising rom the roadbed level to the top of the crossing. The plates are located in position with their plank engaging portions 6 overlying the adjacent ends of the planks as illustrated in Figures 1 and 2 and with their tie engaging portions 8 lying flat upon adjacent ties 12,

such portions 6 and 8 beingrespectively secured to the planks and ties by wood screws, spikes or other preferred fastening devices l3 driven through openings 14 in the plates.

When in this positionthe inclined surface of each plate forms a continuation of the roadbed surface and dragging parts are consequently caused to ride upwardly thereon and pass the crossing without disturbing the latter.

The side portions 9 and 10 serve to reinforce the plates and at the same time prevent moving parts from catching beneath the latter.

The transverse edges of the plates should be bevelled as at 16 and 17 respectively unless the plates at these points are countersunk inthe planks and ties respectively.

What I claim is as follows: A

A crossing plank plate of the type described consisting of a unitary member having an inclined deflector portion of inverted channel cross-section, the longitudinal side last-mentioned portions having transversely edges of the latter being extended doWnspaced spike openings therethrough and Wardly to constitute closed reinforcement bevelled transverse edges, substantially as 10 side portions, horizontal extensions of the described. i v

top and bottom transverse edges of the Signed at the hamlet of Winter, Saskatchsaid deflector portion constituting plankwan, this 18th day of October, 1926.

engaging and tie-engaging portions, said OLIVER JOSEPH KING.
