UNITED STATES PATENT OFFICE SAMUEL L. PORTER AND DUANE PEOK, OF ROCHELLE, ILLINOIS.

IMPROVEMENT IN RAILWAY-TIES.

Specification forming part of Letters Patent No. 158,437, dated January 5, 1.875; application filed i September 19, 1874.

To all whom it may concern:

Beit known that we, SAMUEL L. PORTER and DUANE PEOK, of Rochelle, in the county of Ogle and State of Illinois, have invented a new and Improved Railroad-Tie, of which the following is a specication:

In the accompanying drawing, Figurel represents a top view of our 4improved railroadtie7 and Fig. 2 a vertical longitudinal section of the saine on the line c c, Fig. l.

Similar letters of referepce indicate corresponding parts.

The invention will first be fully described, and then pointed out in the claims.

In the drawing, A A represent the bearings or bed-pieces of our improved tie for rail-joints, which are made of cast iron or other suitable meta-l, with flat top part and flaring supporting sides, that rest upon the gravel, tamped firmly below them. The bed-pieces A are of equal size, placed symmetrically with the longitudinal axis of the track, about three feet long and two feet wide, inv the 'shape shown in Fig. l, for the purpose of forming a broad and solid base for the rails B. Diagonallycrossing braces O connect the bed-pieces A across the track, being recessed at their ends to interlock with short side extensions U of lthe bed-pieces A below the rails, and centrally bolted to a top plate, D, and a bottom bracepiece, E, of which the latter enters into slots a at the inner extremities of bed-pieces A, and secures the rigid and strong lateral connection of the bed-pieces. The form of the bedpieces keeps the gravel dry, and prevents the settling of the same, also the raising of the track by the action of frost. The rails B are secured on the fiat top of the bed-pieces by longitudinal guide-anges b, which secure the base part of the rails, and prevent, by projecting lips or lugs b entering into recess of the rail base, the endwise moving of the rail, while allowing at the same time for the necessary contraction and expansion. This mode of fastening the rails, together with the rigid support of the'bed-pieces, prevents effectually the well-known moving of the track in endwise direction for certain distance, by which frequently a gap of several inches is formed at some joint, while at the saine time the opposite rail may move in the opposite direction, and give the ties a laterally-inclined direction, causing thereby a narrowing of the track and the binding of the rails ou the carwheels. The rails are furthermore secured to the bed-pieces by bolts d with round heads screwed to the under side of the bed-pieces, so that the rails are thus held iirrnly in position thereon, and a superior tie for supporting rail-joints furnished thereby.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. The rail-joint support A A, having extensions O C and cross-bars C C, as and for the purpose described.

2. The combination, with the braces C O, of the central re-enforcements D E, connected and arranged as shown and described.

3. The guide flanges b, attached to bedpieces, and having lips I1 adapted to work in recesses of rail,as and for the purpose specified.

4. The combination of recessed rails, beds having holders b b', and adjustable clampingbolts, to allow the rail to be raised or lowered without moving the beds.
