1 RAILWAY-RAIL STAY.

Specification of Letters Patent.

Patented lFeb. ilet, lltiiiilt.

Application filed May 8, 1909. Serial No. 494,917.

To all whom it may concern: r Be it known that I, J01-IN.M. SCOTT, a c1t1- zen of the United States, residing at Racine,

in the county of Racine and State of WViseonsin, have invented certain new and useful Improvements in RfilllVity-R-ttll Stays, of

' whichthe following is a specification.

I My invention relates to a rail stay or anchor to prevent the longitudinal creeping of railway rails and has for its object to provide a simple and effective device of that character which shall at once he very strong and durable and small, compact and economical of metal.

The improvements of this invention relate pal ticulaily to the type of rail stay in which two jaw-carrying members are clamped upon the rail base by means of a bolt and nut or equivalent'means.

It is one of the objectsof my invention to provide an arrangement of parts by means of which one or both-of the jaws. may be drawn down upon and against the rail base obliquely, so that the clamp of the jaw upon the rail.

against both the edge and the top of the rail base is increased with the turning of the nut.

A further object of my invention is to provide a reinforcement around the clamping-bolt, so as to strengthen the device.

The invention has for a further object to provide a form of device which will utilize a relatively short clamping bolt, thus eeono; mizing metal and adding to the strength of the device and the effectiveness of its grip The invention further contemplates arranging the abutment for the tie substantially centrally of the gripping jaws, so that the strains upon the device will be balanced. It may be said that this form of device is designed particularly for heavy rails where the strains are relatively great.

The invention further contemplates the use of hardened bits or studs in the jaws of ,the clamping members which 'en'gage with pended'thereto.

The invention, in a preferred embodiment, is illustrated in the accompanying drawings, wherein- Figure 1 shows the device in vertical cross section. Fig. 2 is a side elevation of a rail with the rail stay in position. Fig. 3 is a plan view. Fig. 4; is a section on the line 4-4 of Fig. 1, looking in the direction of the arrows. Fig. 5 is an end view of the bolt end of the device. Figs. 6 and 7 are perspective views of the jaw-carrying members Fig. 8 is a cross section of the modified form of device; and Fig. 9 is an elevation of the inside of the movable jaw-carrying member .of the modification shown in Fig. 8.

. Like characters of reference indicate like parts throughout the figures of the drawings.

In the drawings, the rail is indicated by the numeral 8 and its flange by 9.

10 is a tie against which the stay abuts. The stay is shown as consisting of two jawnut for the latter. One of the jaw-carrying members is provided with the abutment for the tie. The device might obviously be con structed of a greater number of parts, suit ably secured together, "without departure from my invent-ion.

()ne of the jaw-carrying members consists of a bar or seat 11, which extends under the rail and which is preferably reinforced by the depending

ribs

12 and 13. At one end of. this bar is the jaw 14:, preferably formed integral therewith and which grips one edge of the rail base. bar is formed a socket l5, which is preferably obliquc to the seat 11, as shown in Fig.

1. Between the socket and the jaw is a de- 15 and sleeve 17 together form a reinforcement for the clamping bolt which takes some of the strain from the bolt and strengthensthe connection between the two jaw-carrying members. The aw carrying members teleintegral therewith a jaw .75 carrying members, a clamping bolt and a At the other end of the scope together on a line oblique to the seating part of the device,'that is, oblique to the rail seat, so that, when nut 20 is screwed down, jaw 18 is drawn down upon the top of the rail, and, at the same time, laterally against the edge of the rail. The'bolt used can be very short and consequently can be made strong without being bulky The arrangement of the abutment 16 substantially midway between the jaws balances the strains upon the device when in use.

In Figs. 8 and 9' I have shown a modified form of device in wh ch the clamping bolt. is given a greater angle of lllclll'liltlOIl'ilIld m which the jaws are provided with hardened pointed studs which bear onto the edges of the rail base. The jaw-carrying members in this form of device'are represented by the-numerals 21 and22 being clamped to gether by the bolt 23 in the manner described excepting that theparts are so constructed as to give a greater inclination to the bolt.

In the jaws are set pointed studs 24 or similar devices of some sort of hard metal. Ordinarily rail anchors are made of malle' able ironwhich of course is softer than the rails. edges of the rail which increases the eflfectiveness of the grip of the anchor. The studs may be securely embedded in the rail by striking the jaws with a hammer. It will be seen that the inclination of the clamping bolt results, when the parts are drawn together, in producing a stress upon the rail base from beneath, above and at the edges.

I wish .it to be understood that I do not limit myself to the exact forms and constructions shown and described, as obvious modifications might be designed which would come within the scope of my invention; For example, the arrangement of the movable, telescoping jaw might be duplicated on the-other side of the device.- Any suitable means may be used, if desired, for hindering the turning of thenut 20. I have shown a split, spring washer 25 against which the nut is driven,
