RAILWAY-TIE.

Specification of Letters Patent.

Patented Jan. 24:, 1911.

Application filed November 4, 1910. Serial No. 590,721.

'Be it known that I, CHARLES O. PEARCE, a citizen of, the United States, residing at Cheneyville, in the parish of Rapides, State of Louisiana, have invented certain new and useful Improvements in Railway-Ties; and I do hereby declare the following to be a full, .clear, and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

' r r This invention relates to railway ties, and

has for an object to provide a tie that will be formed entirely of metal and will secure traflic rails without the use of spikes, fish plates or other securing devices.

A further object 01: the invention'is to rovide a railway tie that will be formed of ut three simple pieces, two of these pieces being cast in the same mold so that but two difilerent molds arev required to manufacture the tie.

A further object of the invention is to provide a railway tie that will obviate the use of rail joints, the tie joining together adjacent rails without mutllating the abutting rail ends in any manner.

In the accompanying drawing forming part of this specification, Figure 1 is a plan view of the tie. Fig. 2 is a side elevation of the tie. Fig. 3 is a cross section taken on the line 3-3 Fig. 2. Fig. 4 is a fragmenerspective View of one of the tie endstar sho ivmg the rail chair and braces. Fig. 5 isadetail perspective view of one of the locking members. Fi 6 is a detail 'perspective view of a locking bolt.

Referring now to the drawing, the tie is seen to comprise a base flange 10 from which rises a vertical web 11, the latter being thickened at its root and merging gradually into the base flange as shown at.12. The bottom face of the base flange is provided with a longitudinal oblong rabbet 13, and both sides of the base flange are provided with rabbets 14 which extend from the outer edge of the flange to nearly the root of the web and communicate with the rabbet 13 in the bottom face of the base flange. This mutilation of the base flange removes nearly the entire central portion of the base flange so that the central portion of the web alone connects the end portions of the flange, the object of this construction being to permit of the two ends of the tie yielding relatively to chairs and reinforce the'chairs against being each other under heavy traffic conditions to prevent springing or warping of the tie.

Formed integral with the top edge of the web are rail chairs '15, these chairs being formed adjacent the ends'of the tie and having their opposite end portions-overhan in and extending nearly to the longitudina edges of the base flange.- For bracing these chairs against displacement; a pair of ribs .16 are formed integral with the sides of the web and have their opposite end portions integral with the. chairs and underlying portions of the base flange. be noted brace the overhanging ends of the snapped off under heavy traffic conditions. The top edge of the web is cut away as shown at 17 adjacent to the free end edges of the chairs, these cut away portions forming seats for the reception of locking members.

Each locking member is preferably T- shaped in outline and comprises shank 18 having a groove 19 formed in one face that permits 0 the shank straddling the seat in the web. The shank terminates in a transversely disposed head 20 having a groove 21 in its working face this groove permitting of the head straddling the free edge of the adjacent chair. The head is further provided in its working face with a rabbet 22 which communicates with the groove ,and whichis sha )ed to conform to the contour of a rail base flange. It will be observed that when the locking member isin operative position the head of the locking member clamps together the rail base flange and the chair 'so that upward disengagement of the rail from the chair is positively prevented.

Formed in the web are tapered openings 23, these openings alining with tapered openings 24 formed in the shanks of the locking members. Through these registering tapered openings, tapered locking pins 25 are inserted, these pins having reduced cylindrical threaded terminals upon'which retaining nuts 26 are mounted, these nuts when screwed up in final position preventing disengagement of the locking members from the web.

It is clear that but three cast pieces are necessary in forming the tie, the tie proper including the rail chairs and brace ribs be- These, ribs it will i ing one piece, and the two locking memthe same mold. Thus but two molds are required in forming the tie so that cheapness of manufacture is greatly promoted.

By referring to Fig. 1 it will be seen that two abutting rail ends are seated on one of the rail chairs, and it .will further be noted that by virtue of the transversely disposed chairs'engaging the abutting rail base flanges and the locking member positively clamping these base flanges to the chair, fish plates, rail joints and like connectors are rendered unnecessary while at the same time the abutting rail ends are held in such close contact as to prevent large spaces existing therebetween but at the same time permitting of sufficient clearness for expansion and contraction of the rails.

What is claimed, is

'1. A railway tie including a base flange having an upstanding rail supporting Web rail chairs arranged transversely of the top edge of said web, and T-shaped locking members having grooved shanks straddling said -web and having grooved heads strad- 1 dling the outer edges of said chairs and en gaged over the base flanges of rails seated thereon.

2. A railway tie including a base flange having an upstanding rail supporting web, rail chairs arranged transversely of the top edge of said web, brace wings projecting lat-- erally from said web and having their 0pposite end portions integral with the end portions of said chairs'and theunderlying portions .ofsaid base flange, and locking members on said web adapted for straddling and clamping together said chairs and the base flanges of rails seated therein.

In testimony whereof, I affix my signature, in presence of two witnesses.
