Specification of Letters Patent. Application filed August 27,

Patented April 30, 1907. 1906. Serial a. 332,171.

To all whom it may concern:

Be it'known that I, IIER'BERT H. HART, a citizen of the United States, and a resident of Chicago, Illinois, have invented a certain new, useful, and Improved Tie-Plate, of which the following is a full, clear, and exact description thereof, such as will enable others skilled in the art to which it appertains to make and use the same.

. Iy invention relates to improvements in railroad tie plates and has special reference to improvements in rolled steel tie plates.

:The object of my invention is to provide a tie plate of superior rail holding qualities and intrinsic meri I My invention consists in a novel article of manufacture, to-wit, a railroad steel tie plate of-the form and distinguished by the novel features hereinafter described and particularly pointed out in the claims.

he invention will be more readily under stood by reference to the accompanying drawings forming a part of this specification and in which;

Figure 1, is a perspective view of a rolled steel tie plate embodying my invention; Fig. 2, is a top viewof the tie plate, showing its form before the spike holes are punched therein; Fig. 3, is a sectional view'on the line X-X of Fig. 2 Fig. 4, is an edge view or elevation of the tie plate; Fig. 5, is an end view thereof; Fig. 6, is a top view of a tie plate blank of modified form; Fig. 7, is an end view thereof; Fig. 8, is a top view of the plate shown'in Fig.6, as it appears after the holes Fig. 9, is a sec ional view on the line YY of Fig. 8.

The novel article of manufacture herein presented is a tie plate and comprises a single piece of rolled steel, rectangular in form. Its

several portionsmay be distinguished and rib named as follows: the rectangular plate porparallel depending flanges, 3-3 latter being usually of less depth than the former;-the'bottom swell or rcin forcing portion,

the top reinforcing portion, 6, and the rail- 5, near the end of the plate; base-holding shoulders, ribs or lugs, 7. The plate contains spike holes, 8 and 9', the former being in alinement with the transverse or shoulder, and the latter, (9), situated in the opposite end of the plate. The thin depending flanges, 3-3 and 4%, are'adapted to sink into th parallel with the grain or e top of a wooden tie, the

I fiber of the tie. I

nal shoulders, 2, are formed, and for the furt preventing the sa 7 i The inner face, 7,

while the ends and outer side of the rib are. The oflice of A principal distinguishing feature of the plate resides in the reinforcing portion or swell, 5, corresponds to the transverse shoulder, but is of less depth and of greater width. The effect of this reinforcement is to strengthen the plate at the point where it receives the greatest thrust or pressure of the rail which it carries, also the additional thickness of the plate at its end possesses the advantage of deepening the spike hole, whereby a greater surface or backing is provided for the spike in hole, 8. The depth of the spike hearing or backing surface is further increased by the top reinforcement, 6, which latter I term the spike hole flat. This flat divides the transthrust of the rail and to spike from said thrust and verse shoulder and its Width substantially corresponds to the distance between the depending flanges, 44, so that the spike hole may be locatedtherebetween as required. In other words, I allow considerable latitude noted that the edge, 6 of the flat, 6, is in alinementwith the inner face of the cross rib, 7. It will be obvious that the shoulder, 7, may extend uninterruptedly from edge to edge of the plate. .I have formed these tie plates in this manner heretofore, but prefer the-form shown, for the reason that it facilitates the punching of the spike hole, 8 ,'lessens the waste and increases the spike beari-ng surface, or spike hole depth. of the plate. Whereit is desiredto secure the tie plate and rail by means of two spikes at the outside of the rail, and only-a single spike at. the inner si ie, I'change the form on the bottom of the plate. This of the plate in the the creeping of the rail. The I to correspond with the flats, 6,

A new article of manufacture, comprising a rolled steel tie plate having a transverse reinforcing or thickened portion, 5, on its bottom, near one end, an overlyingtra-nsverse rib upon its top and also having vertical rein which latter two spike :holes, 8*, are cesses at'the ends of said rib, substantially as punched as shown in Figs. 8 and 91 Asindescribed. 1 dicated in Fig. 7, the flats, 6 may be flush 3. A new article of manufacture, compriswith the top of the plate or slightly elevated ing 2.. rolled steel tie plate having a transverse rib on its top near, one end, provided of Fig. 1.

The proportions and configuration of my with a spike hole and having vertical retie plate may be modified to a considerable cesses at the ends of said rib, substantially as extent without departing from my 'invendescribed. J tion; hence I donot confine my invention to manner shownin Figs. 6 to 9. In this form of the article the bottom of the plate remains the sanie,but the top is modified by providingthe same with three shoulder lugs, 7" 5 7 separated by two spike hole flats, (l -6 4. A new article of manufacture", comprising a rolled steel tie plate having a transverse rib or shoulder on its top, being interrupted to form a spike hole fiat, the lower portion of said plate, beneath said rib or shoulder being thickened or reinforced and said plate having vertical recesses at the ends of said rib, substantially as described.

In testimony whereof, I. have hereunto set scribed. Having thus described my invention, I claim as new and desire to secure by Letters Patent; I I I I 1. A'new'article of manufacture, compris-v ing a rolled steel tie plate composed of a plate portion containing spike holes, a plurality of depending flanges,transverse reinfort ing and rib portions, 5 and 7, upon the bottom and top of. said plate portion respectively, and said plate-portion having Vertical recesses at the ends of said rib portion, substantially as described.-
