THE-PLATE Specification of Letters Patent.

Patented Dec. 8, 19 08.

Application filed July 9, 1906. Serial No. 325,286.

To all whom it may concern:

Be it known that I, BERNARD JAMES Coon- LIN, of the city of Montreal, Province of Quebec, Canada, have invented certain new and useful Im rovements in Tie-Plates; and I do hereby eclare that the following is a full, clear, and exact description of the same.

This invention relates to the type of tieplate known as brace tieplates and is an improvement on the brace tie plate covered by my Letters Patent No. 690,235 December 31, 1901.

The several objects of the present invention are, first, to stren then the construction; secondly, add a gripping surface to the underside of the late; and thirdly, to elevate the outer end of the plate so that when first inserted beneath the rail in the process of track laying it will tend to slightly tip the head of the rail inward and thus secure the result usually attained by what is known as shimming, i. c. lacing small pieces of wood or other material between the tie and the outer side of the rail base.

In carrying out the purposes of my improvements, the tie plate instead of being constructed of plate cut and bent to the desired form as in my patent referred to, is cast either of iron rendered malleable or not, or of steel and the vertical braces thereof while at diagonally opposite corners and of difiering height, as formerly, are reinforced by lateral rib portions, thus securing the desired strengthening; the gripping surface consists of a series of ribs projecting from the bottom of the late, and the elevation of the outer end for shimming the rail, in laying, is secured preferably by making the plate of a tapering thickness, from end to end, or thicker at the outer end than at the inner.

For full comprehension, however, of the invention reference must be had to the accompanying drawings forming a part of this specification in which Figure 1 is a plan view of the improved tie plate; Fig. 2 abottom view; Fig. 3 an outer end view and Fig. 4 a side elevation of the tie plate in place beneath a rail when first laid and showing the inward tip imparted to the rail.

The tie plate consists of base a and braces b and c, forming a single integral casting of iron, rendered malleable.

The base a, in order to rovide for shimming the rail is preferab y tapered in thickness from the outer end (1, which is the thicker, to the inner end e, the thinner, or the same result might be attained by casting a rib (indicated by dotted lines f) along the bottom of the outer end portion, the plate remaining of uniform thickness throughout the remaining portions as shown by the dotted line g indlcating what would then be the bottom of the plate.

The bottom of the plate is provided with the longitudinal ribs h to furnish a means of gripping the tie on which the plate rests and into which the ribs are forced.

The brace b which rises from the end portion of the plate located inside the rail extends, as formerly, only to a height half way up the web of the rail so as to leave the proper clearance for the wheel flange, and it is reinforced by a lateral rib portion 21 on the outside extending from the base along the edge of the bearing face of the brace to the top of same, while a similar rib portion 7' extends in like manner along the lnside of the brace and is su plemented by a triangular wing proj ectio'nh starting and tapering from the base and terminating at a point at the vertical ortion of the brace. The brace c which is coated at the opposite diagonal corner of the plate with relation to brace b and therefore outside the rail is of exactly the same form as that 1) except that it is higher so as to extend to the head of the railand support same against outward thrust as explained in my patent referred to. The plate of course has the usual spike holes m for attaching it to the tie.

My brace tie-plate can be readily set in place after a rail is laid as shown in patent referred to by inserting it beneath the rail and between the tie upon which it is to be set and next to it. The late is then turned to an angle that will bring the braces on each side of the rail flange after which the plate is raised until the base is in contact with the rail-flange and the plate is then turned to a position at right angles to the rail and, finally, and while still beneath the rail, pushed or driven upon the tie to receive it. When in place, spikes (not shown) are driven through the spike-holes m and into the tie, although these spikes are almost superfluous, as the weight of the rail retains the bedplate against displacement and the braces in tu in prevent the lateral displacement of the rai What I claim is as follows 1. A brace tie plate castand being of oblong configuration and having a vertical brace at diagonally opposite corners, each of said braces being adapted to bear upon the Web of the rail and having laterally projecting reinforcing ribs extending along the edge of the bearing face of the same the inside ribs being supplemented by Wing projections, substantially as described.

2. A brace tie plate cast and being of oblong configuration and having avertical brace at diagonally opposite corners, each of said braces being adapted to bear upon the Web of the rail and one of said braces supporting the head of the rail and the other brace being of less height than the head of the rail, the braces having laterally projecting reinforcing ribs extending along the edge of the bearing face of the same the inside ribs being supplemented by Wing projections, substantially as described.

3. A brace tie plate of oblong configuration and having a vertical brace at diagonally opposite corners, each of said braces being adapted to bear upon the Web of the rail and one of said braces supporting the head of the rail and the other brace being of less height than the head of the rail, the base of the plate being of tapering thickness and having a series of ribs on its under surface, substan- O tially as described.

4. A brace tie plate of oblong configuration and having a vertical brace at diagonally opposite corners each of said braces being adapted to bear upon the Web of the rail and one of said braces supporting the head of the rail and the other brace being of less height than the head of the rail, the base of the plate being of tapering thickness and having a series of ribs on its under surface and the braces having laterally projecting reinforcing ribs, substantially as described.

5. A brace tie plate cast of iron and rendered malleable and being of oblong configuration and having a vertical brace at diagonally opposite corners, each of said braces being adapted to bear upon the Web of the rail and one of said braces supporting the head of the rail and the other brace being of less height than the head of the rail, the base of the plate being of tapering thickness and having a series of ribs on its under surface and the braces having laterally proj'ecting'reinforcing ribs With Wing projections from the inside ribs, substantially as described.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing Witnesses.
