RAILROAD-TIE.

Specification of Letters Patent.

Patented Nov. 11, 1913.

' Application filed July 5, 1911, Serial No. 636,985. Renewed. August 16, 1913. Serial No. 785,123.

To all whom it may concern: Be it known that I, COLIN ALLERTON, a citizen of the United States, residing at \Vest Homestead, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Railroad-Ties, of which the following is a specification.

This invention relates to improvements in railroad ties and the distinctive feature consists in providing a form of tie or joint for the rails which is adapted to be held in rigid contact therewith without the use of rivets, tie bolts or similar fastening means.

One of the objects of my invention is to provide a rigid joint for rails embracing the minimum number of parts, that may readily be assembled and dismantled and when assembled will expose above the sup port for the rails but two elements each clamping the opposite flange of the rail, thereby simplifying the structure and reducing the cost of manufacture.

With these and other objects in View, my invention consists in the combination and arrangement of structural elements herein after described, shown in the drawings and then more particularly pointed out in the appended claims.

Referring to the drawings, Figure 1 is a side elevation, partly in section, of my rail road tie, Fig. 2 is a top plan view thereof, showing the recess in which are disposed the clamping parts, Fig. 3 is an end elevation in section. of the base or support for the rails forming part of my invention taken on the line XX in Fig. 2 and Fig. 4 is a top' plan view in detail of the clamp element 5 on the line Y-Y of Fig. 2. I

In the drawings wherein similar reference characters designate similar parts 1 is a longitudinal base or support preferably made of steel upon which the rails 4 are fastened by the clamps 5 and their accessories. The base is formed preferably trapezoidal in form as shown in Fig. ,3 and upon the upper surface at opposite ends, a longitudinal recess is formed having transversely extending

terminal branches

2 and 2 respectively disposed at opposite sides with respect to the median line of the recess. The sides 2 having the recess between them are formed at opposite points with recesses 3 of lesser depth than the longitudinal recess 2 .within. which the rails snugly fit as shown in Fig. 2, it being understood that for curves in the rails, the curves in the recesses will be correspondingly trued. 5 are the clamping members and comprise each a flat base 6,-

member 5 is formed with outwardly project-.

ing portions 7 and 8 at opposite sides which are suitably spaced apart from the base 6 to form in the one case a recess adapted to embrace one flange of a rail and in the other case, a substantially rectangular recess whose top edge is flush with the top of the base 1. In operation the rails 4 are fitted within the recesses 3 and the base of a clamp 5 fitted with the recess or track 2 at. opposite sides of the rail and both clamp members are then slid until the portions 6 underlie the rail 4 and the opposite extensions 6 are flat upon the support 3. Metallic slabs 9, preferably also of steel and of the same thickness as the base 6 of the clamps 5, being shaped to snugly fit the remaining aliquot part of the track or recess 2 are then stamped or otherwise mounted in position within the recess '5 alongside the clamp 5, the edges of the slabs 9 and clamps 8 being suitably finished so that the cheeks 6 and of the clamps 5 will bind against the opposite flanges of the rail. To complete the joint or tie additional slabs 10 shaped to snugly fit the uncovered portions of the recesses 2 are interposed between the shoulders formed by the support 1 and the clamp 5 so that the slabs 10 will completely overlie the slabs 9 and extensions 6 of the said clamps and thus continue the flush surface of'the support 1. By this arrangement a positively acting joint is formed in a very attractive manner since only the elements 5 will project above the surface of said support. The branch recesses 2 and 2* at each end of the support are for facilitating the insertion of appropriate tools wherewith to remove or disengage the slabs and thereby release the clamps and remove the rails;

My tie may be constructed of metal, con crete, wood or other desirable material.

I claim and desire to secure by Letters Patent 1. A railroad tie having a longitudinal recess therein, two shoes, each shoe being formed at opposite sides with spaced outwardly-extending portions whereby recesses are provided, said shoes having their bases fitted in said longitudinal recess and receiving the flanges of a rail in the recesses of one side, metallic slabs fitted in the ends of said longitudinal recess and each jamming one shoe against said rail, and a metallic slab fitted in each end of said longitudinal recess and in the other recess of the adjacent shoe, said last-named slabs each overlying one of the first-named slabs and jamming the shoe against the rail.

2. A metallic railroad tie having a longitudinal recess, said recess formed at diagonally-opposite ends With transverse extensions opening into the sides of said tie, two

metallic shoes each formed at one side with a flange-receiving part, a flat base formed on each shoe being fitted in said recess, said bases forming a seat for a rail when said Shoes engage the flanges of said rail, metallic slabs fitted at the ends of said recess and resting on the bottom thereof, said slabs jamming the bases of said shoes to cause them to hold the rail, eachvof said shoes formed with a recess, and slabs overlying said first-named slabs and fitted in said longitudinal recess and in the recesses of said shoes, said first and second-named slabs being of uniform Width with said longitudinal recess and arranged to jam said shoes against the rail. y

In testimony whereof I aflix my signature in presence of two Witnesses.
