RAILROAD J CINT-CHAIR.

Speccaton of Letters Pate-nt.

Application filed March 29, '1910. Serial No. 552,139.

To all whom it may concer/n:

Be it known that I, PETER RADOMAN a citizen of the United States, and a resident of Bed Lodge, in the county of Carbon and State of Montana, have invented a new and Improved Railroad Joint-Chair, of which the following is a full, clear, andveXact description.

The purpose of this invention is to provide a railroad joint chair of novel form, that adapts it to incase the'baseflanges and webs of two track rails at adjacent ends '.thereof;'and also to provide means for se .curing the improved chair on the rails so as Reference is to be had to the accompanying drawings, forming a part of this speciication, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is a perspective view of the improved chair and spike applied for securing the meeting ends of two track rails upon a cross tie of a railroad; Fig. 2 is a transverse sectional view, taken substantially on the line 2-2 in Fig. 1; Fig. 3 is a perspective view of the improved railroad chair; and Fig. l is a perspective view of the improved railroad spike. i

In the drawings that show the construction and application of the invention, A, A, indicate endportions of track rails having the usual T-shape in-cross section, each embodying a head vor ball, two base anges A', A', and a web portion A2, that integrally connects the flanges with the head, the latter overhanging the web as shown in Figs. 1 and 2.

The improved chair embodies a base plate B, having proper width to receive the pair of base flanges A, of each track rail. The side edges of the base plate B are integrally joined to lower portions of two upwardly and inwardly inclined flanges B, that in service have loose cont-act with the upper faces of the base anges A', A. Upon the upper edges of the inclined flanges B, two vertical flanges B2 are integrally formed, having parallel inner 4surfaces .that are spaced apart a distance' .which adapts them to loosely embrace. the sides of the webs A2,

on two track 'rail ends, when the'latter are' inserted an equal distance within-the shoelike track rail chair. Four spaced, perforations a, are formed oppositely in each vertical flange B2, and register with? similar perforations formed in the rail websv A2,

when the en d portions of the similar track Patented Sept. 27, 1910. l

rails are inserted an'equal distance within the opposite ends of the chair. -Throughthe flanges B2, and the webs A2, four similar ,bolts C, are inserted, said bolts having heads C thereon, at like ends, and threads on their,

opposite ends, whereon nuts .C2 are screwed,

when the bolts C have been fully inserted "j through the flanges B2, and the intervening Webs A2.

It' will be seen that the end-portions of the track rails will be exactly alined when they are inserted and secured within one of the improved chairs, and thus will be pre-- f vented from vert-ical or lateral displacement when seated and secured on the cross ties. D, I

as indicated in Figs. 1 and 2.

Apreferred means forV securingtlie chairs of a track line upon the cross ties, consists of .spikes shaped as shown in the. drawings. The body of t-he improved spike, as shown at E in the drawings, is rectangular in cross section, and at one end is pointed by beveling its four sides till they meet` at the free eX- tremity of the. spike'body, as shown at Y), in Figs. 2 and 4. Upon the lopposite end of the body E, a rectangular flange E is integrally formed, but projects from one side of the said body and produces a head thereon. On the four corners c of the spike body, spaced teeth c are formed that are inclined upwardly and outwardly,and thus are adapted for hooked engagement within 'downward therethrough and fit loosely therein. In each perforation cl an offset rectangular enlargement d is laterally formed,

said enlargements being located in the sides ofthe perforations that are parallel with and adjacent to the vertical anges B2 and having their bottom walls beveled, and* as' appears in Fig. 2, the head E', on a respective spike body E, willoccupy the offset enlargement d, and be completely embedded therein when the spike body is fully inserted down 'into a cross tie whereon the chair is seated.

As shown in Figs. 2 and 4, the body of the improved spike is bent so as to slightly curve 1t laterally, thus rendering the outermost side of each spike body concave, and the side thereof that is below the head lange E convex.

It will be apparent, that the rails forming a railroad track, if secured place on the cross ties by means of'the'improved chairs and spikes, will be so fixed in place, that they cannot be accidentally' displaced, and

the track rails will be held parallel with each other under all conditions of service..

Having thus described my invention I claim as new, and desire to secure by Letters Patent- 1. A railroad track rail chair, consisting of a base plate, inclined flanges on the side edges of the base. plate, and arallel spaced flanges vertically projecting rom the inner ed' es of the inclinedl anges, said base plate an inclined flanges having rectangular ver- .tical perfora'tions therein, said perforations wardly inclmed flanges and two verticalV flanges and provided with rectangular'perforations in the base and inclined anges, said perforations having offset rectangular lateral extensions, the bottom walls of which are beveled, and railroad spikes having rectangular bodies, each spike having an 'offset and inclined head that occupies and lits the offset enlargement or lateral extension of a respective perforation.

In testimony whereof I have signed my name to this specification in the presence of Vtwo subscribing witnesses.
