RAILROAD-TIE.

SPECIFICATION forming part of Letters Patent No. 785,053, dated March 14, 1905.

Application filed August 17,1904. Serial No. 221,132.

To (I/U/ 10720772, 712% may concern.-

Be it known that I, JAMES A. SIEERD, a citizen of the United States, residing at Warren, in the county of Huntington and State of Indiana, have invented certain new and useful Improvements in Railway-Ties, of which the following is a specification.

This invention embodies a peculiar form of metallic tie for railroads, and comprises, essentially, the tie proper,in combination with special clamping devices carried thereby and adapted to engage the rails to rigidly secure the same in position upon the tie.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is to be had to the following description and accompanying drawings.

While the essential and characteristic features of the invention are susceptible of modification, still the preferred embodiment of the invention is illustrated in the accompanying drawings, in which Figure 1 is a perspective view showing embodiment of my invention in practical use. Fig. 2 is a vertical longitudinal sectional'view through the tie, the rails being shown in position thereon. Fig. 3 is plan view of the tie, the rails being removed and the lock device cooperating with the adjusting-bar likewise displaced. Fig. 4 is a vertical transverse sectional View taken about the line .11 m of Fig. 2. Fig. 5 is a detail perspective view of one of the railclamping members. Fig. 6 is a perspective View of the adjusting-bar.

Corresponding and like parts are referred to in the following description and -indicated in all the views of the drawings by the same reference characters.

The tie 1 is a hollow formation and is preferably made of cast metal or the like. The hollow formation. of the tie lends a certain amount of elasticity thereto-a necessary characteristic in devices of this character. Ad-

jacent the ends of the tie l are formed rail-. seats 2, said seats constituting transverse cutaway portions of the uppermost side of the tie arranged to receive the rails 3 in proper spaced relation. One side of each of the seats 2 of the tie is undercut, as shown at 4, so that said tie will overhang one of the basal flanges of the rail 3 when the latter is in position upon the tie 1. One side of each seat therefore positively engages the rail received therein, and clamp members 5 are movably mounted within the hollow portion of the tie for positive cooperation with the said rails. The clamp members 5 consist of blocks or bodies slidably mounted within the tie, and each of the members 5 is formed with an integral undercut flange 6 on the upper side thereof. said flange positively engaging the side of the rail opposite to that which is engaged by the undercut portion 1 of the adjacent seat 2. The clamp members 5 being movable longitudinally of the tie are adapted to operate against one side of adjacent ra-il, andin addition to engaging said rails, as above described, said clamp members force the said rail hard against the portion 4 of the adjacent seat 2.

The means for actuating the clamp members 5 isan adjusting-bar 7, disposed within the tie l and arranged longitudinally thereof. The ends of said adjusting-bar 7 are threaded, as shown at 8, and received in threaded openings 9 in the clamp members 5. The adjusting-bar 7 is of squared formation, as shown at "10, centrally of its ends, so that any suitable implement may be applied, such as a wrench or similardevice, in order.to rotate said bar to effect movement of the members 5. In order to have access to the squared portion 10 of the adjusting-bar, the tie l is provided with an opening 11 in the upper side thereof, said opening being situated between the ends of said tie. At one side of the opening 11 in the hollow space of the tie is formed a vertical integral web 12, having an opening therein, through which passes the bar 7. The bar 00- operates with the web to actuate the members 5 in their longitudinal movement by bearing against one side of the part 12. A cap-plate 13 normally closes the opening 11 of the tie 1, and this plate is provided with means engaging the squared portion 10 of the adjusting; bar to prevent rotation of said bar, which might cause the members 5 to loosen and disengage from the rail adjacent thereto. The lock means consists of the solid extension 14,

projecting from the under side of the plate 13, and said extension 14 is provided with a recess 15 to receive the portion of the bar 7 The recess is also of square formation, and when the portion 10 of the bar 7 is received therein said bar is locked from rotary movement, and this is of no small advantage in securing the clamp members 5 from movement under all conditions of service. The threads at the, ends of the bar 7 run in the same direction, so that the bar when operated will bear against the web 12, pulling upon the clamp member which is farther from the squared portion thereof, at the same time exerting a pushing force against the adjacent clamp member or that at the right end of the bar, as shown in the drawings. 7 1

Having thus described the invention, what is claimed as new isv 1. In combination, a hollow railroad-tie provided with rail-seats adjacent the ends thereof, clamp members adjustable within the hollow portion of the tie, engaging flanges projecting upward from said members for cooperation with the rails, and an adjusting-bar for effecting simultaneous actuation of the clamp members.

2. In combination, ahollow railroad-tie provided with rail-seats adjacent the ends thereof, clamp members adjustable Within the hollow portion of the tie, engaging flanges projecting upward from said members for cooperation with the rails, and an adjusting-bar having its ends threaded and received by the clamp members.

3. In combination, ahollow railroad-tie provided with rail-seats adjacent its ends, railclamp members adjustable in said tie, an adjusting-bar cooperating with said clamp members to effect movement thereof, and means for preventing movement of the adj Listing-bar.

4. In combination, a hollow railroad-tie provided with rail-seats adjacent its ends, rail clamp members movable longitudinally in said tie, said tie being provided between its ends and in the hollow portion thereof with a vertical web having an opening therethrough, an adjusting-bar passing through the web and having its opposite ends received by the clamping members for actuation thereof, the said bar being squared between its ends, the tie JAMES A.
