RAILWAY-TIE RAILE-CLAMP.

Specification of Letters Patent.

Patented Mar. 7,1916.

Application filed September 13, 1915 Serial lilo. 5(1420.

To all whom it may concern Be it known that 1, JOHN F. HAwLnY, a citizen of the United States, residing at Chillicothe, in the county of Livingston and State of Missouri, have invented certain new and useful Improvements in Railway- Ties and Rail-Clamps, of which the following is a specification.

This invention contemplates an improved railway tie and clamp and has to do particularly with improvements in the construction disclosed in my pending application filed June 15, 1915, Serial No. 32,352.

The invention has as its primary ob ect to provide a hollow tie which may be formed of steel, a composition, or any other suitable material and having integral abutments adapted to rigidly support the rails andt also provide webs or anchoring members ntegral with the abutments and depending into the body of the tie to adjustably receive clamping members arranged to cooperate with the said ,abutments in engaging the rails.

A further object of the invention is to so construct the tie that the anchoring members will be inwardly spaced from the ends of the tie so that the adjustable connections of the clamping members will be protected by the body of the tie.

The invention has as a further object, in this connection, to so form the tie that the adjustable connections of the clamping members will be readily accessible, And a still further object of the invention is to provide an improved form of clamp ng member which may be constructed as a single casting but which will, nevertheless, be adapted to yield when engaged with a rail to thus efiiciently perform its function.

Other and incidental objects will appear as the description proceeds and in the drawings wherein I have illustrated the preferred embodiment .of the invention and wherein similar reference characters designate corresponding parts throughout the several views,

Figure 1 is a perspective view of a tie constructed in accordance with the present invention showing the manner in which the tie is adapted to receive the rails and also illustrating the manner in which the clamping members are adapted to engage the rails, Fig. 2 is a fragmentary horizontal sectional view showing the adjustable mounting of the clamping members upon the tie and particularly illustrating the manner in which the tie is formed to provide abutments for the rails as well as the anchoring members associated therewith, Fig. 3 is a similar view showing a slightly modified form of tie and the manner in which the clamping member of the present invention may be used in connection therewith.

The tie of the present invention includes ody portion 0 sub tan ia ly rec a gular 1 c os -se ti n and whi h, a p viou ly in imated, m y be f rme o t el, a co position, or any other suitable material. '1 he body portion .of the tie is hollow providing side walls 11' having outwardly diverging inner fac a d l s n he ttom o t tie is a bottom wall 12. Formed on the upper side of the tie adjacent opposite exiti s e of, are p andi g utments 13 w ch are P en e o ar a h eth r and are provided with convex upper faces, Preferably, the abutments extend from side t Sid f e ody on Of h ie and are undercut to receive the base flanges of the a ls c ve i llv h wn a 14 w th t s id a utm t enga the eb 0f the ails po th outer ide ereof. na- P e' nto the dv of th t and in gral with the abllfiments 13, are transversely extending webs or anchoring members 14L which a ppo ends, a e s int gral with the side walls 11 of the tie. It will be noted that the abutments are inwardly spaced from the ends of the tie and preferably project downwardly from the outer extreinities of the abutments. These anchorns memb s, in bei g nteg al t he abntments and with the sides of the tie, ill be ri i ly s pported and in h can'- necti it is point d out that t e a ho i g members will provide transversely extendbraces for the side walls of the tie and will thus materially contribute to the rigidity and durability of the tie structure. Formed the upper side of the tie at the outer ends of the abutments 13, are transversely extending openings 15.

Formed in the upper side of the tie adjacent the inner sides of the abutments 13 are longitudinally extending slots or openings 16 and fitted through the said slots are clamping members 17. Each of these clam-ping members is preferably formed as a single casting .of suitable resilient metal and includes a shank 18 from one extremity of which extends a flattened reduced neck 19 arranged at substantially right angles to the shank. Formed on the upper extremity of the neck is a laterally enlarged head 20 connected with the neck by a portion extending laterally therefrom in the direction with the shank 18. As most clearly shown in Fig. 2 of the drawings, the clamping members are mounted upon the tie with the necks 19 thereof freely received within the slots 16 and with the heads 20 fitting over the base flanges of the rails upon the inner sides thereof and hearing against the inner faces of the rail webs. The anchoring members 14 are provided with suitable openings which freely receive the shanks 18 of the clamping members and screw threaded upon the outer extremities of the said shanks are nuts 21. In any instance where the clamping members are to be used at a joint between the meeting ends of adjacent rails, the heads thereof are provided with projecting studs 22 received in suitable openings formed in the rail webs. Otherwise, these studs may be eliminated.

It will now be noted that the clamping members are adjustably connected to the anchoring members It and by properly turning the nuts 21, the heads 20 of the clamping members may be brought into binding engagement with the rail webs to cooperate with the abutments 13. In this connection, particular attention is directed to the fact that the reduced necks 19 of the clamping members provide relatively yieldable elements interposed between the shanks of the clamping members and the heads 20, adapted to yield under the binding influence of the nuts 21 and consequently, resiliently urge the heads of the clamping members against the rail webs. Thus, any wear will be taken up by the clamping members, while the said members will also act to eliminate vibration.

The purpose in rigidly supporting the anchoring members 14 will now be apparent since the normal tension upon the clamping members 17 will be communicated directly to these anchoring members as will also any strain upon the clamping members caused by rolling stock passing over the rails. The anchoring members are so ar ranged that the nuts 21 of the clamping members will be disposed immediately oppo site the openings 15 in the upper side of the tie so that while the tie body will provide an efficient protection or housing for the said nuts, still, access through the said openings may be easily had to the nuts for the purpose of removal or adjustment.

In Fig. 3 of the drawings, I have shown a slight modification in the present construction which relates more particularly to the tie structure. In this modification, the anchoring members 23 are formed flush with the ends of the tie and the necessity for the openings 15 disclosed in connection with the preferred form of the invention is thus eliminated since the nuts 21 of the clamping members will also consequently be disposed at the ends of the tie where they will be readily accessible. In this connec tion, it should be stated that the shanks of the clamping members when used in connection with this form of tie will be slightly longer than is necessary in the form of the invention previously described. In this modification, the body of the tie is provided with integral abutments 24 which are some- H what different in cross-sectional outline from the abutments of the preferred form of the invention, the abutments 24 being somewhat reduced to fit against the outer sides of the rails and conforming more closely to the general contour of the heads of the clamping members. Otherwise the construction shown in this modification is identical with that of the preferred form of the invention, and a further description thereof will accordingly not be given.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

1. In a device of the character described, a railway tie including a body portion provided with an upstanding abutment, an anchoring member carried by the body portion, and a clamping member associated with the anchoring member and including a shank having a yieldable neck extending therefrom and provided with a head adapt- 10 ed to engage a rail seating against said abutment.

2. In a device of the character described, a railway tie including a body portion provided with an upstanding abutment, an an- 105 choring member carried by the body portion, and a clamping member associated with the anchoring member and including a shank having a reduced yieldable neck extending therefrom and provided with a head 110 adapted to engage the web of a rail seating against said abutment with the abutment engaging the rail web opposite to said head.

8. In a device of the character described, a railway tie including a body portion pro- 115 vided with an upstanding abutment, an anchoring member carried by the body portion, and a clamping member associated with the anchoring member and including a shank and a head yieldably connected to the 120 shank by a neck with the neck supporting the head in position to engage a rail seating against said abutment.

4. In a device of the character described, a' railway tie having side walls and a top 125 wall closing one extremity of the tie upon its upper side, an upstanding abutment carried by the tie, an anchoring member depending between the side walls, there being an opening formed in the top wall in spaced 130 relation to the said extremity of the tie and contiguous to said abutment, a clamping member carried by the anchoring member and adapted to engage a rail seated upon the tie to confront said abutment, and means connecting the clamping member with the anchoring member and accessible through said opening, the said means being disposed in spaced relation to the opening and housed within the closed extremity of the tie.

5. In a device of the character described, a railway tie having top and side walls, an upstanding abutment carried by the tie, an anchoring member depending from one extremity of the abutment between the side walls, a clamping member carried by the anchoring member and adapted to engage a rail seated upon the tie to confront said abutment with the anchoring member disposed in spaced relation upon one side of the base of the rail, and means connecting the clamping member with the anchoring member, the said means being housed within the tie and protected by the top wall thereof.
