To n/ZZ whom, it new concern.-

Be it known that I, ALEXANDER MITCHELL MOYLAN, a citizen of the United States. residin g at Century, in the county of Escambia and State of Florida, have invented certain new and useful Improvements in Railway-Ties, of which the following is a specification.

This invention embodies improvements in railway-ties of metallic construction primarily, and comprises a support oftheclass above mentioned composed, essentially, of complementary tie-sections, said sections being of a peculiar form whereby they may be assembled to constitute a rigid bearing for a rail or number of rails.

The tie when constructed in accordance with my invention includes means for mounting the rails in position thereon and may be utilized practieably as the gage for determining the positions of the rails, thereby doing away with a special instrument for accomplishing this last service.

.Further, the invention consists of special means, forming a part ofthe tie construction, for actuating the complementary sections of the tie relative to each other in order to effect cooperation of said sections with the rails to be supgorted thereon in securing the said rails in proper position.

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

While the invention may be adapted to different forms and conditions by changes in the structure and minor details without departing from the spirit or essential features thereof, still' the preferred embodiment thereof is shown in the accompanying drawings, in which Figure 1 is a perspective view showing the application of the invention. Fig. 2 is a longitudinal sectional view through the tie, the rails being shown in position thereon. Fig. 3 is a perspective view, the tie-sections being reversed, showing the rail-engaging members carried by under sides of the tie-sections in cooperation with the rails. Fig. 4 is a plan view showing the positions of the parts of the tie preparatory to assemblage of the tie-sections, the

latter being shown separated and the keepers for said sections being shown in positions ready for cooperation therewith. Fig. 5 is a perspective view of one of the tie-sections looking toward the upper side thereof. Fig. 6 is a perspective view of the other tie member looking toward the under side thereof. Fig. 7 is a detail perspective view of the turnbuckle or adjusting device. Fig. 8 is a detail perspective view of one of the keepers used for holding the tie-sections together. Fig. 9 is a transverse sectional view taken on a line about central of the tie, parts assembled. Fig. 10 is a combined perspective view showing interlocking portions of each section with the tie adjacent, the sections being partially broken away.

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

As illustrated the tie l is shown in a construction adapted to support two rails. However, the principle of the invention readily admits of the formation of ties of a length sufficient to receive and effectively carry the rails of a double track. The tie is of sectional construction, as mentioned before, and the sections'are designated 2. Each section is of exactly the same form, and this is animportant advantage, since the sections may be assembled without discrimination as to the exact fit of the adjacent cooperating parts thereof. A plurality of extensions 3 are projected laterally from each section 2 of the tie, and the extensions of one section are adapted to overlap portions of the other section to afford an interlocking connection therebetween. For the purposes of the description the extensions 3 may be said to be undercut, and said extensions overlap cut-away or downward l y-inclined portions 4 of the opposite sections 2. One side of the respective sections 2 is continuous or unbroken, the other side being, however, interrupted, due to the formation of the extensions 3 and portions 4. However, when the sections 2 are assembled and in operative position the extensions 3 so fit into the cut-away portions 4 of the respective sections thata tie of substantially oblong solid form is produced. The cut-away portions 4 of each section in which the extensions 3 of the other section are received are of somewhat greater length thansaid extensions in order that the latter may have a certain amount of longitudinal movement or play, the purpose of which will be noted hereinafter.

In order to prevent separation of the sections 2 of the tie,scveral means may be utilized, and that relied upon in ordinary railroad construction consists of a plurality ofkeepers 5, adapted to engage the two sections of the tie, and thereby effectively prevent movement of the extensions of one section out of the cutaway portions of the other. The keepers 5 are preferably made of metal and consist of a bar, preferably flat, the ends of which are extended upwardly, as shown at 6, so as to engage opposite sides of the tie or the continuous unbroken side of each tie-section. The keepers are also formed with upwardly-extended projections 7 between the ends thereof, which projections are received in elongated slots 8, located in adjacent extensions 3, and cut-away portions 4 of each section 2 of the tie. The keepers 5 rest flat or with the parts 6 and 7 down as the sections 2 are forced together, after which the keepers are turned upwardly, so that the portions 6 engage the sections and the projections 7 are received in the slots 8.

In bridge or trestle construction the keepers 5 may be dispensed with, and in lieu thereof, fastening-bolts or the like may be utilized to hold the sections 2 togetl'icr, and said bolts may at the same time position the tie upon the bridge or trestle structure, as the case may be.

For the above purpose the sections 2 are provided with a plurality of vertical openings 9, adapted to match or register when the sections are assembled, and the bolts used for preventing separation of the sections and securing the ties of the supporting structure will be passed through said openings.

The means for mounting or securing the rails to the tie 1 consists of engaging parts carried by the respective sections 2 and ada pted to engage the basal portions of the rails supported upon the tie 1 and designed to be reversible, and in view of this different forms of engaging means may be provided upon upper and lower sides thereof. The upper side of the tie, as shown, is cut away to form seats 11 to receive the rails 10. The seats 11 are formed by the undercut portions 12, located at adjacent inner extremities of the end extensions of each section 2. The undercutportions 12 of the sections 2 form flanges adapted to overlap and positively engage the base of the rail, and the space between the portions 12 forms a seat receiving the rail. The space between the portions 12 of each section is adapted to be reduced or enlarged by longitudinal adjustment of the sections relative to each other. The means for adjusting the sections 2 by longitudinal movement comprises an expanding device very similar to a turnbuckle, and this device is interposed between the inner extensions 3 of each section 2, being adapted to force said extensions apart, and thereby impart a longitudinal movement to one of the sections 2 relative to its mate section. The adjusting device is composed of bars 13, seated in elongated recesses 14, formed in the upper sides of the inner extensions 3 of each section, and the inner ends of said bars 13 are threaded to receive a turnbuckle 15, adapted to be screwed thereon. The remote extremities of the bars 13 are beveled, as shown at 13, so as to engage beneath the undercut extremity of each recess- 14. The recesses 14 are enlarged at the adjacent extremities thereof, so as to readily receive the turnbuckle 15, and the latter is provided with a series of openings 16, adapted to receive the end of a lever or bar by which the turnbuckle may be rotated. By rotation of the part 15 in one direction a separating movement of the inner extensions 3 of each section will be imparted thereto, and such movement is designed to reduce or decrease the size of the seats 11 of the tie and force the engaging members 12 of each section hard against the bases of the rails received in the seats 11 to firmly position the rails therein. Ifnecessary for purposes of repair, replacement of the parts, or the like, the part 15 may be rotated so as to admit of longitudinal movement of the sections 2 relative to each other in order to remove the rails 10 from the seats 11 or for any other such purpose, as above mentioned.

Upon the under side of the tie 1 is provided amodilied form of means for clamping the rails thereto, and in the last instance the end extension 3 of each section 2 is provided upon its under side with outwardly projecting spaced lugs 17, said lugs being located adjacent the inner extremity of the extension. The inner extensions 3 of each section 2 are also provided with an outwardly-projecting loop 18 at the outer extremities thereof, and each loop is designed to receive an engaging member in the form ofa pin 19. The pin 19 is adapted to be forced beneath the loop 18 and its outer end to engage the base of the rail 10.- A head 20 at the other extremity of the pin 19 is adapted to enter a depression 21, formed upon theinner extension 3 of each section 2 adjacent the loop 18, said pin being thereby locked from accidental displacement. The rails in the last-described construction are received between the lugs 17 of one section 2 and the pin 19 of the other section, the parts 17 and 19 performing substantially the same function as the parts 12, utilized upon the upper side of the tie for attaching the rails thereto. If necessary, the adjusting device composed of the parts 13 and 15 may be util- IIO ized upon the under side of the rail in cooperation with the engaging members 17 and 19; but said device may be dispensed with, since the pin 19 will fully answer all purposes as a rigid securing means for the rails 10.

It may be desirable, in connection with the tie as above described, to use a base of sheet metal or the like, and it will be noted that such can be readily secured to the under side of the tie, thereby admitting of diminishing the size of the parts of the tie construction in a manner readily apparent. Further, in certain instances it is contemplated to reduce vibration and noise by the introduction or insertion of fiber material or the like, such as asbestos or paper, between the extensions 3 and the cut-away portions 4. The material (indicated at 22 in the drawings) would be housed and protected by the tie-sections. The keepers 5 have the portion 6 thereof slightly inturned, so as to frictionally bind against the sections 2 in their engaging relation.

Having thus described the invention, what is claimed as new is 1. A railway-tie embodying sections, each section having port-ions overlapping and interlocking with like portions upon the other section, and means for preventing separation of the sections.

2. A railway-tie embodying sections, extensions projected from each section and interlocking with like extensions projected from the other section, and means for preventing separation of the sections.

3. A railway-tie comprising sections, one of said sections being provided with lateral extensions projected therefrom at a point between its ends for cooperation with the other section, and means for preventing separation of the sections. p

4. A railway-tie comprising sections, each section embodying parts interlocking with the other section, means-for preventing separation of the sections, and rail-engaging means upon the upper and lower sides of the tie and including engaging parts carried by each section thereof.

5. A railway-tie embodying sections, both sections being of the same form and having a straight unbroken side, and members extending from this side and interlocking with like members of the other section.

6. A railway-tie embodying sections having lateral interlocking members cooperating with each other, and rail-seats upon adjacent interlocking members of the sections and adapted to be reduced or enlarged by longitudinal movement of the sections relative to each other.

7. A railway-tie embodying complementary sections longitudinally movable relative to each other, rail-engaging members projected from the respective sections, an adjusting device cooperating with the complementary sections of the tie to efiect longitudinal movement thereof and fix the same at an ascertained adjustment, each adjusting device comprising bars engaging the respective sections and means for separating said bars.

8. A railway-tie embodying complementary sections, extensions projected laterally from each section and adapted to interlock with the other section, an adjusting device for effecting longitudinal movement of the sections relative to each other and consisting of bars engaging extensions of the respective sections, and a turnbuckle cooperating with said bars for the purpose specified.

9. A railway-tie comprising sections having interlocking overlapping parts extended laterally therefrom, and keepers engaging the side of each of the sections to prevent separation thereof.

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