DEVICE FOR PREVENTING RAILS FROM SPREADING.

SPECIFICATION forming part of Letters Patent No. 501,678, dated July 18, 1893.*

Application iiled April 26, 1893. Serial No. 471.948. (No model.)

10. It will be seen that the two bars 4 and O To all whom it may concern:

Be it known that I, THOMAS HEARHELY DA- HILL, a citizen of the United States, residing at Alfred Centre, in the county of Allegany and State of New York, have invented a new and useful Device to Prevent Rails from Spreading, ofv which the following is a specification.

This invention relates to devices for preventing rails from spreading, and has for its object to improve this class of devices by simplifying the construction and operation of the same and making them in such manner as to be easily and quickly applied and avoid material projection after they are in position, being especially intended for application to curves in railroad rails. l

With these and other objects in view, the invention consists of the construction and arrangement of the parts thereof as will be hereinafter more fully described and claimed.

In the drawings: Figure 1 is a transverse vertical section of relatively-situated railroad rails and a tie or sleeper supporting the'same, showing the improved device applied thereto. Fig. 2 is a detail perspective view of the parts of the improved device detached and separated.

Similar numerals of reference indicate corresponding parts in both figures of the drawings.

Referring to the drawings, the numeral 1 designates ordinary rails, having the common lower anges 2, and which are supported in connection with an ordinary form of wood tie or sleeper 3.

The numerals 4 and 5 represent a pair of base-bars that each have outwardly upturned hooked ends 6,whose upper walls, as at 7, conforni to the outer contourof the lower flange e are adapted to align with the bolt-openings are thus made separable at their inner ends and virtually form a continuous bar when fastened together, so that theycan be putinwardly from the outside of the rails without raising or disturbing the latter. On top of the bars 4 and 5 is removably placed akeeperbar13,with a pair of longitudinally-disposed bolt-openings 14 at the center thereof that are adapted to align with the bolt-openings 10 and 12, of the bars 4 and, and whereby all the parts atthe center are unitedly secured at one operation by a single pair of bolts and nuts l5. The outer ends of the said keeperbar 13 is constructed with heads 16, of greater thickness than the major part of the said bar, and Whose outer edges, 17, are curved to snugly tit over the inside portions of lthe upper surfaces of the flanges 2 of the rails. When the parts are thus arranged it will be seen that the rails will be prevented from spreading, and to more positively insure this desired operation or effect, and to produce a stability and rigidity of position to the several parts, the said heads 16, of the keeper-bar 13, are formed with bolt-openings 18, that align with the bolt-openings 8 of the bars 4 and 5, through which are passed single bolts and nuts 19, to thereby positively hold the hooks 6 and the heads 16 in proper relation to the rail-iianges 2. It will be seen that the keeper-bar 13, mounted over the break-joint of the bars 4 and 5, produces a rigid formation with the convenience of separating said bars 4 and 5 from each other when desired to remove the saine, or to shove them inwardlyendwise under the rails in applying them in position without disturbing the rails.

Changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having. described the invention, what is claimed as new is-.-

1n a device of the character set forth, the

combination of a pair of bars having their in-l ner ends recessed on opposite sides and supplied with a pair of longitudinally-disposed bolt-openings arranged to engage with each other, and the outer ends thereof formed with ICO 1o openings that align with the similar openings at the center of the united lower bar, andboits uniting said parts at the center and at the ends, substantially as described.

In testimony that I claim the foregoing as my own I have hereto afxed my signature in I5 the presence of two Witnesses.

THOMAS HEARHELY DAHILL. Witnesses:

J. PETTIBONE, GREEN CHAMPLIN.
