RAIL-SUPPORT.

SPECIFICATION forming part of Letters Patent No.1 l769,266, dated September 6, 1904.

Application 'lled March 17, 1904.

To all whom it may concern.

' Utica, Licking county, State of Ohio, have invented certain new and useful Improvements in Rail-Supports; and my preferred manner of carrying out the invention is set forth in the following full, clear, and exact description, terminating with claims particularly specifying the novelty.

This invention relates to railways, and more particularly to that class of devices thereunder known as rail-supports.

The object is to provide effective means for clamping the rail; and to this end the inven tion may be said to consist in certain novel structures and arrangement of parts, which will be fully described in the following specication and illustrated in the drawings, in which-' Figure 1 is a perspective view of the inven` tion as applied to a tie. Fig. 2 is a longitudinal section on line X X, Fig. 1. Fig. 3 is a plan view of one of the basel members with the sliding clamp in the middle and the rest of the clamping mechanism removed. Fig. 4: is a plan View of the slide. Fig. 5 is a longitudinal section through Fig. 4 on line y y. Fig. 6 is a side elevation of the outer clamp. Fig. 7 is a front elevation of Fig. 6. Fig. 8 is a perspective view of the inner clamp.

The letter B designates the base member, in this case forming the end section of a tie T, which comprises, in addition to the end sections, a central section O, whose length may be varied to suit different conditions. The inner ends of the base members may be provided with depending 'iianges F to prevent lateral creeping of the tie.

R indicates the rails, only one of which -is shown. The base member is divided internally by a horizontal shelf 1 into two'cornpartments, the upper of which, A, is shorter than y the lower, leaving an exposed platform 2, which is continuous with the shelf. The top 3 of the upper compartment is provided on its inner edge with a rectangular notch 5 and centrally with a rectangular aperture A. Asecond aperture, 6, in the shelf is directly in alinemen-t with the last-named aperture. The pur- Serial No. 198,690. (No model.)

pose of the shelf is to facilitate removing from the open inner end of compartment A the slide which is described below.

The numeral? designates a sliding clamp comprising recurved ends 8, embracing lateral' iianges 9 on the base member, and a straight bar 10, having on one edge a rectangular notch 11 and on the other a continuous undercut bevel 12. Notch 11 is in alinement with notch 5 and is provided at its inner edge with inclined portion 18.

Occupying the upper compartment is a slide 14, having a rectangular body portion 15 and a threaded extension 16. yThe body portion is provided with a'central aperture 17, having on its side walls inwardly-projecting iianges 18. These flanges extend from the rear wall of the aperture for about half the length of the opening land are beveled upwardly and forwardly on their lower edges, forming camways. Thus two regions .are formed inthe aperture, the rearward of which is restricted by the inwardly-projecting flanges.

Apertures e and 6 in the base member are of such size as to receive and firmly brace the stem 23 of outer clamp 19. As shown in Figs. 6 and 7 this clamp has the form of a short blunt spike. It is provided with the laterallyprojecting head 2O for engagement'with the rail-base and has the reduced portion 21 intermediate its length. The lower shoulders 22, formed at the junction of the reduced portionWith thestem, are inclined downwardly and rearwardly, forming'complementary camways to those on the slide. The stem on the outer clamp is of such diameter as to pass readily through the forward portion of the central aperture of the slide. It is evident that a forward motion of the slide will cause the camways on the iianges to engage with the -camways of the clamp, forcing the latter downward.

The inner end of the upper compartment A is occupied by the rectangular body ofinner clamp 23. Referring particularly to Fig. 8, it will be seen that this clamp has a reduced head 211, which is adapted to iit w-ithin notch 5 in the top of the base member and is provided with an undercut bevel 25 to engage with the inclined portion of notch 11 on the IOO sliding clamp. It is further provided with a longitudinal opening 26 for the reception of extension 16 of the slide. Anut 27 fits upon the threaded end of the extension outside of the clamp.

In assembling the parts of the rail-support the sliding clamp is first slipped upon the top of the base member. Then the slide is introduced into the upper compartment, so that the forward portion of its aperture is in alinement with apertures 4L and 6. At this stage or earlier the rail may be placed in position. The outer clamp is dropped into place, with. its head resting upon the base of' the rail. The inner clamp is pushed into the compartment along the projecting extension of the slide, and finally the nut is tightened. This causes the slide to move inward, and, as explained, the outer clamp is drawn forcibly down upon the rail-base. Simultaneously the inner clamp is being pushed toward the rail and its head rides upon the beveled notch of the sliding clamp, jamming the latter inwardly and downwardly against its side of' the rail-base.

While for convenience I have shown my device as applied to a tie, I wish it to be understood that the invention lies in the clamping mechanism, which I intend to claim broadly, and it is to be noted that the sliding clamp may be omitted and the inner clamp forced into direct engagement with the rail without departing from the spirit of my invention.

What is claimed as new isl. In a device of the character described, the combination with the rail and a base member having alined vertical apertures; of a slide fitting within said fmember and comprising a body portion and a lateral extension, said body portion being provided with an aperture adapted to aline with the last-named apertures, an outer clamp comprising a head engaging with the rail-base and a stem passing through all said apertures, an inner clamp loosely mounted on the latter extension of the slide and having a head for clamping the railbase, and means for causing said slide and inner clamp to move toward each other.
