Specification of Letters Patent.A

Application filed October 5, 1908. Serial No. 456,105.

To all whom it may concern: r

Be it known that I, ROBERT Law, a citizen of the United States, residing at Toledo, in

invented a new and useful Improvement in Tie-Plates, of which the following is a speciiication.

My invention relates to a tie plate, and has for its object to provide a light, strong, durable, and economical late for railway ties, that is adapted for etter securing a rail to a tie and prevent the rail from spreading to protect the spikes and the tie from the wear of the rail; that is adapted to be inserted between the tie and the rail without loosening the rail from the next adjacent ties and that is self seating and self leveling on a worn tie. I accomplish these objects by constructing a tie plate as hereinafter described and illust-rated in the drawings in whicli- Figure l is a top view of a tie plate constructed in accordance with my invention. Fig. 2 is a longitudinal section of the saine on line Amel, with a rail, tie, and spike indicated by dotted lines. F ig. 3 is an en larged cross section of the saine, (partly broken away), on line B-B, and Fig. 4 is a perspective view of the saine.

In the drawings, l designates a tie plate constructed in accordance with my iiivention, and is 'termed from a wrought metal plate oit suitable dimensions, and provided,- by being compressed in a suitable punch and forming die,-with the hollow bosses :2, projecting from the top of the plate, suitable for receiving the spikes that secure the rail and the plate to the tie, and located to :t'orni abutinents 3 on opposite sides or" the rail base, engaging the flanges. The plate thus formed, being iiat on its under tace, is

`held firmly secured to the tie by the spikes 4, which are driven through the hollow bosses 2, into the tie 5, with the heads ot' the spikes engaging the iianges of the rail 5. 'lhus secured, the wear caused by the lengtliwise movement of the rail,-produced by the motion of the trains or by expansion or contraction of the raihwis received bythe plate instead of the tie and the spikes, and lateral pressure on the rail in either direction, is resisted equally by the spikes on both sides of the rail, thereby increasing the security ot the rail against spreading.

To adapt my tie plate for convenient application to established tracks, Without removingl or raising the rail, I have provided it on the one side with the bevels 7, forming the cutting edges 8 on the end 'portions oi one side edge of the plate, that extend beyond the outer edges of the rail flanges. The cutting edges 8 are in the plane of the bottoni 'ace of the plate, and between the cutting edges, the portion 9 of the plate is rounded or beveled on the under side. Thus constructed,l when it is desired 4to use the plate on a tie which has a channel worn in its top face by the rail base, after removing the spikes from the tie, the plate is 'placed underneath the rail with the hollow bosses on opposite sides of the rail lianges and` its top face engaging the bottom ot' the rail base, and with the edges 8 engagmg the side of tlie tie at the level of the bottom of the is driven between the tie and the rail base,

the bossesv 2 forming directing guides, and astlie plate is driven between the tie and thc rails, t-lie edges 8 cut away the portion of the wood of the tie along the sides of the channel, so that the plate when in its proper position on the tie, is firmly seated thereon.

There the tie is not worn by the rail, the plate may in like manner be introduced between the rail and the tie, as the rounded central portion 9 ot the plate will wedge between the tie and the rail and prevent the edges 8 from cutting into the wood of the tie.

By forming in a punch press as described, a pairof hollow bosses 3 on each end portion of the plate, the plate is not only provided with abutments to prevent lateral movement of the rail independent of the plate, and with a plurality of spike holes on cach side ot' the rail, but the plate is thereby greatly strengthened against buckling, without iucreasing the weight of the plate. rThe plate thus provided with hollow bosses is also without the tendency,-`which is very commonly"incident to plates having transverse ribs forming rail abutments,to break along the inner side of the abutn'ieiits, or through the spike holes, which as commonly constructed constitute their points or linesof greatest weakness, whereas, in my construction, the bosses 2, which provide the spike holes of my tie :,plate, greatly increase its strength. They falso prevent access of water through the spi/'ke holes to the tie immediately around thle spike, and the decay of the tie and the loosening vof the spiketherein, commonly arising therefrom.

Patenten rieb. 22, loro.

Vhat I claim to be new is- 1. A tie plate comprising a wrought metal plate having formed on each end portion thereof by being struck up in a punch and die press7 a plurality of tubular bosses projecting from the upper face of the plate in position to form abutments for engaging each side of a rail base, and adapted to receive spikes for securing the rail to the tie, said plate having both the upper and lower faces otherwise plain surfaces.

2. A tie plate for railways, Comprising a Wrought metal plate,'having.fom1ed on each end portion a pair of hollow bosses, adapted 'to engage and forni abutments for the flanges of a rail base, and to receive Spikes for securing the plate to a tie, and a rail on the plate, said plate having downward bevels along one side edge, forming cutting` edges on the end portions of the plate extending beyond the outer edges of the rail base, and an upward bevel between the cutting edges, substantially as and for the purpose set forth.

In Y witness whereof I have hereunto signed my name in the presence of two subscribing Witnesses, this 21st day of September, 1908. l
