- METALLIC CROSS-TIE.

SPECIFICATION forming part of Letters Patent No. 754,693, dated March 15, 1904:.

Application filed July 28, 1903. Serial No. 167,337. (No model.)

To all whmn it may concern:

Be it known that I, CYRUS WEsrY'PLA'r'r, a citizen of the United States, residing at Windfall, in the county of Tipton and State of Indiana, have invented a new and useful Metallic Cross-Tie, of which the following is a specification.

The invention relates to improvements in metallic cross-ties.

The object of the present invention is to improve the construction of metallic cross-ties and to provide a simple'and comparatively inexpensive steel railway cross tie of great strength and durability adapted to be readily placed in position and capable of expanding and contracting without liability of spreading the rails or otherwise interfering with the proper alinement and parallelism of the same.

A further object of the invention is to provide a metallic cross-tie which will permit the expansion and contraction of the rails and which will have one end firmly secured to one rail and its other end yieldably connected with the opposite rail, whereby the tie is adapted to ex pand and contract independently of the rails. 7 Another object of the invention is to provide a cross-tie of this character adapted to be reversely arranged, so that eachof the rails of a track will be firmly and positively heldat regular intervals to preserve the proper parallelism and to prevent spreading. With these and other objects in view the invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended, it being understood that various changes in the form, proportion, size, and minor details of construction within the scope of the claims may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings, Figure 1 is a plan view of a portion of a track provided with metallic cross-ties constructed in accordance with this invention. longitudinally of one of the cross-ties. Fig. 3 is an end View of one of the cross-ties, showing a portionof one of the rails. Fig. 4 is a detail View of one of the fastening devices.

Fig. 2 is a sectional view taken Like numerals of reference designate corresponding parts in all the figures of the drawings.

1 designates a metallic cross-tie, preferably constructed of steel and provided at its lower face with a central longitudinal flange 2 to strengthen the cross-tie and to enable a maximum amount of strength to be obtained from a minimum amount of material; but the crosstie may be otherwise flanged or constructed to secure this result. The cross-tie is provided at its upper face with

end enlargements

3 and 4, forming chairs or seats for the rails 5 of a track and provided with inward and outward extensions located at opposite sides of the cross-tie and reversely arranged, as clearly shown in Fig. 1.

The enlargement 3, which receives and which is rigidly connected with one of the rails, is provided at its outer extension with a rigid upwardly and inwardly projecting jaw 6, forming a recess between its engaging portion and the upper face of the enlargement or chair to receive the outer portion of the bottom flange of the rail, as clearly shown in Fig. 2 of the drawings. The engaging portion of the integral jaw 6 fits against the web of the rail at the outer face thereof and extends from the bottom flange to the lower face of the head of the rail, whereby the rail is firmly supported and held against outward movement. The inner extension 7 of the said enlargement or chair 3 is provided with a longitudinal slot 8, which receives the head 9 of a bolt 10 for engaging the rail 5 at the inner side thereof, whereby the rail is firmly clamped between the fastening device 10 and the rigid jaw 6. The fastening device 10 consists of an approximately L-shaped bolt having a projecting head of the shape of that of an ordinary spike, and the shank of the bolt extends through a bore or opening 11 of the enlargement or chair 3 and receives a nut '12. The outer extension of the enlargement or chair 3 is one-half the width of the cross-tie and a recess 13 thereby formed at the opposite side of the cross-tie for the bolt 12. Washers 14: are preferably interposed between the nut and the adjacent end face of the enlargement or chair 3. The slot of the inner extension protects the fastening device from the ballast and the side walls of the slot support the engaging portion of the fastening device. The other enlargement or chair, 4, is provided in its

extensions

15 and 16 with

slots

17 and 18 for the engaging portion 19 of fastening devices 20, which are similar in shape to the fastening device 10, heretofore described. The inner and outer extensions of the enlargement or chair 4: are one-half the width of the crosstie, and

recesses

21 and 22 are provided for the reception of the nuts 23 of the fastening devices and springs 24, which are interposed between the nuts and the adjacent end faces of the enlargement or chair, whereby the fastening devices are yieldingly held in engagement with the adjacent rail. By this construction the rail is yieldably engaged by the fastening devices, which permit the metallic cross-ties to expand and contract without spreading or otherwise effecting the rails. One of the rails is firmly and positively clamped by each cross-tie, and any expansion and contraction will therefore take place at the other end of each cross-tie, and the rails will not be spread by such expansion and contraction. The metallic cross-ties are reversely arranged, as illustrated in Fig. l of the drawings, and the rails are thereby positively clamped at regular intervals and are securely held in proper position, so that the yieldable character of the fastening devices at one end of each cross-tie does not affect the solidity of the rails.

The slots of the inner and outer extensions of the enlargement or chair 4 protect the engaging portions of the fastening devices from the ballast, and these fastening devices pass through longitudinal bores or openings of the enlargement or chair 4, and, if desired, the entire fastening devices may be shielded from the ballast by suitable casings. The inner extensions of the enlargements or chairs are connected by a longitudinal web or flange 25, located at the upper face of the cross-tie and adapted to strengthen the same. The longitudinal flanges at the top and bottom of the cross-tie also afford sufficient bearing-surfaces or engaging faces to prevent the crosstie from shifting in the ballast.

It will be seen that the cross-tie is exceedingly simple and inexpensive in construction, that it possesses great strength and durability, and that it is capable of expanding and contracting without spreading the rails or other wise interfering with the proper alinement and parallelism of the same. It will also be apparent that it will not interfere with the expansion and contraction of the rails and that it is as eflective in this respect as the ordinary wooden cross-tie; also it will be clear that as the ties are reversely arranged the rails will be rigidly held at regular intervals and that the rigid attachment of the cross-tie at one end will cause the expansion and contraction to occur at the other end, which is provided with yieldable fastening devices. Furthermore, the oppositely-disposed yieldable fastening devices will permit the cross-ties to expand and contract without releasing their grip on the rail. The cross-tie facilitates the ready removal of a rail when the same becomes worn or a new rail is required for any other purpose.

The cross-tie can also be modified to adapt itl for switches, frogs, guard-rails, and the li (c.
