' RAILWAY-RAIL STAY.

Specification of Letters Patent.

Patented March 27, 1906.

' Applicationmedrovemberia,1905. serian. 287.045.

-nal creeping of the rail; and the invention has, more particularly, reference to the speciesof rail-stay in which the member which draws the jaws into position to grip the rail is formed with a hook, serving the function of one of said jaws, as shown in my Patent No. 779,104, dated January 3, 1905. 1

The object of my present invention-is to reduce the cost of manufacture of the rail- .stay and at the same time increase the elli- ,y ciency and reliability of its operation; and ,to that end the invention consists in the improved construction and combination of the component parts o'l the rail-stay, as hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a transverse section of a railway-rail with my im rovedrail-stay applied thereto. Fig. 2 is a p an view of the same, Fig. 3 is a transverse section on the line X X in Fig. 2,A and Fi .4 is a longitudinal section on the linev Y Y inig. 2. viewed in the direction of the arrow.

In the said drawings, A represents therail- Way-rail, and B the underlying cross-tie which supports the rail on the road-bed. f

'a and a denote the two jaws, which are' shaped to grip 'the flanges l) b of the rail and may be forced into their gripping position by -sideof the rail and connected to the said jaws and provided with a nut d, applied to the screw-threaded end of the bolt and bearing on the outer side of the jaw (L to tighten the gri of the jaws. The opposite end of the o t c is bent upward and toward the main orv xtral portion. of the bolt in the form of a k c,which in my prior invention hereinflange of the rail and serve the function ofthe arate jaw a. of my present invention,

ch jaw is composed of east metal, and r; be-seatedwlthin thishookA thus inexpensive to manufacture and capable of obtaining a secure hold on the flange b of the rail. The bolt c may be of lany suiti able shape in .cross-section; but in order to reduce the cost ol" its man ufaeture I prefer to form it of a round or cylindrica rod of wrought-iron or steel.

One end of said rod is screw-threaded for the purpose hereinafter explained,'and the opposite end of said rod is bent up in the shape of the hook c', which embraces the back and top oi the jaw a and receives a secure hold thereon by means of llanges e e at o posite sides of a groove e', in which the hoo c rests. Said llanges at the same time serve to reinforce the-jaw to more safely resist strain due to its grip on the rail.

The jaw a is provided with a transverse aperture. j, which receives through it vthe screw-threaded end of the bolt: c. An inwardly-extending bearing g, formed on .the jaw (1. and engaging the under side of the bolt c and braced by the tieabutting flange h, serves to strengthen the said jaw. To the protruding threaded end of the bolt c is ap-l plied a nut d, which bears on the back of the jaw a., and by turning the said nut so as to press very tigl1tly`on said jaw the bolt is caused to force both jaws into position to firmly grip the rail.

I preferably lorm the jaw a with -two tiealnltting-llu-nges i and l1 :lt opposite sides of the jaw to allow said jaw to be placed on 'either side of the rnil,.und thus obviate the vexpense of making right and left patterns for casting the jaw'. ',lo cause the jaws to obtain firm and secure holds on the rail, I secure to the interior of each jaw asteel or other 9o very hard metal gripping-plate fi, preferably seated rmly in a recess in the overhanging lip of the jaw. Said p ate is formed with sharp ribsV Z,`which bite'the rail, as shown i-n Fig. 4 of the drawings.

Where the jaw on one ilange of the rail is provided merely by-forming the bolt c into a ook, as shown in the prior art, especially if 'the' hooked it is diicu t to secure a sufficiently tig-ht grip upon that flange of the railwhich is engaged by such hook; but by -means of my present-invention' I rtain all of the simplicity and cheaplness of structure inherent in usin a simple ook on one end of the bolt c, an by providing a tooth-carrying j aw adaptedto` -sired grip on. the rail, which ortion of the bolt is cylindrical,

attain vthe denot only pre- 3o the device to the vents any longitudinal movement of the rail, but prevents any twisting of lthe rail-anchor with relation. to the flange.

The jaw e, as stated, isV preferably provided with teeth, which may or may not be formed directly on the jaw itself or on a hardened insert carried by the jaw, and such teeth are preferably 1n the forni of sharpedged ribs extending transversely of the raili'o flange rather than into its edge. By using this construction I provide a number of teeth each of which needs to but slightly bite into the top of the rail-flange, so that. there is no i appreciable cutting into or weakening of the i5 rail, while 1n the aggregate the grip of all of these teeth in the top of the rail-flange is such as to absolutely prevent any movement. of the jaw with relation to the vrail, orvice versa.

While7 as stated, the nut may be tight- 2o ened so as to force the jaws into gripping engagement with the rail-flanges, in common practico the desired bite of the jaws upon the rail-flanges will be more readily attained by sufficiently heavy blows with a sledge-haninier used to 'drive the jaws upon the railing one side of the rail and one side of thc l 3 5 cross-tim a bolt extending across the under side of the rail and adjustably supported at one end of said engaging means and formed with a hook at its opposite end, separatelyforined rail-engaging means interposed be- .io tween the said hook and rail, and means for tightening the holds of said bolt on the :i foresaid rail-engaging means.
