ANDREW MORRISON, OF 'PITTSBURG, PENNSYLVANIA GUARD-RAIL.

Specification of Letters Patent.

' A li tio filsd April 11.1907. Serial No. 367.683.

- To all whom it may concern:

Be it known that I, ANDREW MORRISON, of Pittsburg, Allegheny county, Pennsylvania, have invented a new and useful Improvement in Guard-Rails, of which the following is a full, clear, and exact description, reference being had to, the accompanying drawin s, forming part of this speci cation, in whic 1- Figure 1 is a cross-sectional view showing one form of my improved guard fail as applied; and Figs. 2, 3 and 4 are cross-sections showing modified forms of-the guard rail.

My invention is designed to provide a guard rail which can be easily and cheaply rolled, and which is so constructed as to permit its head to be placed in proper relation to the head of the main rail, while the bases-of the two rails can be separated to such an extent as to permit of adjustments and the use of secure fastening devices.

To this end, my invention consists in a guard rail having-its head lying entirely to one side of its web, the web being either vertical or inclined, and the base'flanges being of equal width, or: one flange wider than the other, as may be preferred.

Inxthe accom anyingdrawing, in Fig. 1 the guard rail is formed with an inclined web 2 having a head 3 which lies entirely to one side of the web, the two base flanges of the rail being shown as of substantially equal width.

in the form shown in Fig. 2, that flange 4 which is overhun by the head of the rail is made narrower t an the opposite flan 'e 5. This permits. the use of a narrower hea Inthe form shown in Figs. 3- and .4, the web 6 is vertical, and the head 7, which is entirely to one side of this web, as in the other figures, is extended sufliciently to overhang the narrower base flan e 8. The

form shown in Fig. 4 is similar to t at in- Fig. 3, except that both base flanges 9 are of equal width, but are preferably somewhat shorter than the standard width.

The guard rail together with the main rail 10, may be secured to the ties in any suitable manner. In Fig. ll have shown it seated upon'the tie plate 11, the main'rail being secured by the spikes 12, andfthe guard rail being secured by spikes 13 engaging its outer edge, and by a clip or tongue 14 struck up in the plate 11 engaging its inner edge.

In all of the forms shown, the head of the guard rail is extended laterallv a suflicient distance to overhang the base flange, the vertical plane of the outer edge of such flange passing through the head at a point between its guard edge and the junction of the head with the web.

The upper surface of the head may be horizontal, or it may be inclined somewhat as This form of rail may be readily and cheaply rolled, thus shown in Figs. 1- and 2.

avoiding the necessity for planing or machining the base flanges. The formation .of the head entirely to one side of the web enables the latter to be extended into proper relation to the main rail, while leaving a substantial separation between the bases of the main and guard rails, without using any more metal in theformation of the head than is necessary in the forms heretofore used, in which the head extends at both sides.

What I clalm is:

1. As anew article of manufacture, a

rolled guard rail having a head lying en tirely to oneside of its web; substantially as described.

2. As anew article of manufacture, a.

rolled guard rail having an inclined web, and a head lying entirely to one side of the web substantially as described.

l 3. As a new article of manufacture, a rolled guard rail having rolled base flanges of unequal width, a web, and a head portion lying entirely to one side of the web and overhanging the narrower base flange; sub staritially as described.

4. As a new article of manufacture, a

rolled guard rail having base flanges, a web, a head lying entirely to one side of the web and overhanging one of the base flanges, the I vertical plane of the edge of said flange assing through the head at a point beyon the juncture of the head and flange; substantially as described. 5.. As a new article of manufacture, a rolled guard. rail having one of its flanges narrower than the other, an inclined web,

and a head lying entirely to one side of the web .and overhanging the narrower base flange, the vertical plane of theedge of said flange passing tilroligh the head of therail at a head lying entirely to one side of the Web 10 a, Boint bevond its juncture with the Web; in the direction towards which the web is insu stantially as described. clined; substantiafly as described.

As a new article if manufacture, s. In testimony whereof, I have hereunte set roiled guard mil having a, head lying en myha'nd.

tireiy to one side of theeenter of its base; ANDREW MORRISON. substantially as described. Witnesses:

7. As a new article of manufacture, a LAURENCE H. LEE,

Boiled guard rail having ail-inclined Web, and. H. M. CORWIN.
