TIE-PLATE.

Specification of Letters Patent.

Patented Sept. 9, 1913. Divided and this application filed May 27, 1912.

Serial No. 700,096.

Jr., a `citizen `of the United States, and resident of St. Louis, Missouri, have invented cert-ain new and useful Improvements in Tie-Plates, of which the following is a specication containing a full, clear, and exact description, reference .being had to the accompanying' drawings, forming a part ereof.

My invention relates to improvements in tie plates, and the object of my invention is to provide a tie plate having a plurality of spaced apart projections on its upper face and adjacent each side margin of the plate. The innermost ends of the projections aline in rows paralleling the sidemargins of the plate in order to form shoulders against which the side margins of the rail-base may engage. Certain of the projections are perforated to receive spikes which may be driven through the plates, their heads overlapping and engaging the base of the rail and the material of the projections outside of the spike openings serving as a backing for the shank of the spike.

This is a divisional application from the application iiled by me on June 6, 1910, Serial No. 565,319. g

With the above purposes in View my invention consists in certain novel features of construction and arrangement of parts as will be hereinafter' more fully described, pointed out in the claims and illust-rated by the accompanying drawings, in which- Figure l is a plan of a length of material from which tie plates may be sheared; Fig. 2 is a plan of one of my improved plates sheared from a length of'material as shown in Fig. 1 and having the spike openings formed therein; Fig. 3 is a transverse, sectional elevation taken on the line 3-3 of Fig. 2; Fig. 4 is a plan illustrating a modified form of tie plate; and Fig. 5 s a transverse, sectional elevation taken on the line 5 5 of Fig. 4.

Referring by numerals to the accompanying drawings: 6 designates the body portion of the tie plate which provides a rail- Y bearing surface. Formed on the upper face of the tie plate and integral therewith are the oppositely disposed projections 7, the inner margins 8 and 9 of which projections are arranged in alining rows on either side of the rail-bearing surface and between ,of the base of t-he rail.

which rows of projections the rail base is placed. Certain, or if desired all, of the projections 7 are perforated in order to form spike openings l0, the spike openings being removed from the margins 8 of the projections 7 on one side of the plate and formed through and including the margin 9 of the projections 7 on the other side of the plate, in order that the spikes driven in the last mentioned side of the plate will have their shanks bear against the margin In plan each of the preferably triangularof such shape as will projections 7 is shaped, or at least `leave a portion of the side margins of the head of a driven spike overlap a projection,

7 in order that a claw may be introduced `under the head of the spike to draw the spike; j j

As-.shown in the drawings, especial attention being directed to Figs-2 and 3, it is to be observed that the spike openings have a comparatively large backing for the shank of the spike to bear against, thus when a spike is being seated it is directed at all times against the rail instead of away from the rail. It is to be observed further in-Fig. 3 that the upper surfaces of each of the projections 7 incline downwardly and inwardly in order that screw spikes may be employed in such manner that their heads will bear against the bases of the rails instead of against the upper surfaces of the projections.

In Figs. 4.- and 5, the projections 7 are of substantially the same shape as shown in my preferred form, except that they consist each of two converging walls ll'which are spaced apart in order that the spike openings 10 may be formed through the body 6 of the plate only, thereby simplifying punching or forming of the spike openings.

The plates of this invention are designed with especial attention given to the formation thereof by rolling, and for this reason the projections on one side of the plate are out of registration with the projections on the other side of the plate, so that there will be substantially the same amount of material between the rollers forming the plates at all times.

As shown in Fig. 2, there are spike openings 12 formed through the body portion 6 of the plates and are laterally removed from the projections 7 So that the spikes may be driven through the plate to engage the bases of rails of dilterent Widths.

I claim: Y

1. A tie plate, pressed from a single piece of material and provided with a series of separate projections, the inner Walls of whichl are in alineinent and form a maxi inurn base for the edge of the rail, there be-l ing a spike opening formed through one of said projections, and an auxiliary opening formed through the rail-bearing surface of the plate whereby s'aid tie plates may be used on rails of different Widths. j

2. As a new article of manufacture;l a tie plate having a rail-bearing surface and adjacent the side Vmangins or the rail-'bearing surface a plurality of spaced-apart upward projections, there being spike` openings formed rthrough said Y projections and through the rail-bearing surface.

3. As a new article of manufacture,- a tie' plate having arail-bearing surface and, integral rows or spaced-'apart projections on the upper surface fof the tie plate contigue ous to the side margins of therail-bearing surface, there being spike openings formed through certain'V er the projections laterally reinoved frein the line of the rail base', and there being spike openings formed through Veefeiin other ef the projections and threugh V in plan the rail-bearing surface innlineiwith the line ofthe rail base.

4. As a new artiele of "nfanufacture, a tieA plate constructed ora single piece of material having a rail-bearing surface and havingupward projections Whichare spaced apart and located in alinement with 'ea'c'li' otherand adjacent each side 'or'fthe r'ailbearing surface, each of said projec-V tions being substantially triangular-shaped downwardly Y and inwardly, there being spike openings formed through certain of said projections and thebody ofthe plate Wholly Within the 'margins of said projecf tions, there beingv spike openingsjformed through certain other of the projections and the body of theplate and `located adjacent the inside margins'of said projections, and

there being spike openings formed through the rail-bearing surface removed fronrsaid projections, substantially as shown and :torV

the purposes stated.
