THOMAS BREEN, OF KNOWLTON, PENNSYLVANIA.

RAILROAD-TIE.

SPECIFICATION forming part of Letters Patent No. 272,850, dated February 27, 1883.

Application filed April 18, 1882. (No model.)

To all whom it may concern:

Be it known that I, THOMAS BREEN, a citizen of the United States, residing at Knowlton, in the county of Delaware and State of Pennsylvania, have invented certain new and useful Improvements in Railroad-Ties, of which the following is a specification, reference being had therein to the accompanyingdrawings.

My invention relatesto an improvement in railroad-ties and it consists in the tiesA and A, the blocks (3, the fish-plates B, in connection with the ties A, the screw-spikes d, and in the construction, combination, and arrangement of the parts, as hereinafter more fully specified.

In the drawings, Figure l is aplan view. Fig. 2 is a side elevation, and Figs. 3, 4, an 5 are detail views.

A represents a metallic railroad-tie, having its ends b b bent over against and conformed to the shape of the foot of the rail upon which in practice it is closely fitted. That part'of each tie which spans the space between the rails and screw-spikes (Z d is twisted; but each tie is also formed into a flattened metal bar, (1, beneath the rails, where it is adapted to and fittedinto recesses D,formed in the sleeperblocks G. The railroad-tie A is also twisted and formed into a flattened bar; but at one end thereof it projects upward vertically to form the fish-plate B. This end is conformed to the shape of the base of the rail until it reaches a line in the same vertical plane perpendicular to the edge of the head of the rail, and then it projects vertically until its upper end reaches the same plane as the top of the rail, as shown in Fig. 3. The plate B, Fig. 5, is located at the junction of two rails, on the inner side of the rail, and opposite to plate B,

to which it is secured by bolts 6 e, and to this 0 end oblong bolt-orifices are provided in the rails. The opposite end of this tube is con-- formed to the contour of the rail in the same manner as shown and described in tie A. The

lateral ends of the sleeper-blocks O are inclined 45 outwardly from top to bottom and provided with longitudinal recesses, wherein the ties are fitted, as shown. These blocks may be made of wood, the slag of iron-furnaces, or of any other suitable material, whereby ordinary Q wooden ties are dispensed with, and a great economy in the cost of construction of railroads is accomplished. Besides, it will be observed that I also effect an economy in the number of spikes employed, and am thus enabled to construct a railroad much cheaper and more durable than otherwise possible.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-
