' RAILPCHAIR.

Specification of Letters Patent.

Patented Nov. 1 1, 1913.

Application filed April 4, 1913. Serial No. 758,924.

To (ZZZ whom it may concern:

Be it known that I, WILLIAM J. Bnn'rnn, a citizen of the United States, residing at Louisville, in the county of Jeflerson and State of Kentucky, have invented certain new and useful Improvements in Rail- Chairs, of which the following is a specification.

This invention relates in rail chairs.

The primary object of the invention is to provide a chair to receive the meeting ends of railroad rails with means for effectually Wedging each of the rails in the chair and so arrange the Wedging means that the members which constitute the same prevent the displacement of each other.

A further object of the invention is to provide a chair with rail locking means which may be conveniently assembled on the chair, the locking means constituting I are held against displacement by means other than ing contact with the rails or the chair.

For a full understanding of the invention, reference is to be had to the following description and accompanying drawing, in which Figure l is a side elevation; Fig. 2 is a perspective view of the chair; Fig. 3 is a section on the line 38 of Fig. 1; Fig. 4 is a perspective view of one of the wedge members; and Fig. 5 is a section on the line 5-5 of Fig. 1.

Corresponding and like parts are referred to in the following description and indicated in all the views of the accompanying draw ing by the same reference characters.

In the drawings, 10 designates the chair which consists of the base 11 and the 1ongitudinally extending side or web portions 12 and 13 which embrace the web of the rail. The side portion 13 is formed at its ends with the laterally extending portions let which are formed integral with the base 11, these lateral extensions being each-provided with a threaded aperture.

The inner faces of the webs 12 and 13 conform generally to the shape of the rail. The inner face of the web 13 is provided with a groove 15 which is curved transversely and which is deeper at the ends of the web than at its center, the groove gradually decreasing in depth as it nears the center of the web.

The chair is secured to the cross ties by to an improvement other and with the their wedgwedge members are bolts which engage the edge portions of the base 11. The meeting ends of the rails are inserted between the webs 12 and 13, and with their ends thus assembled 'a wedge member 16, such as is shown in Fig. 5, is inserted in each end of the chair; The wedge members 16 are provided with rounded surfaces 17, which, when a member is inserted, enters the. groove 15 of the web.

The wedges are of a length approximately equal to the length of the chair, and when a Wedge member 16 is inserted in each end of the chair the tapered portions 18 of the members overlap. Thus, when the wedges are driven firmly into place, their rounded portions 17 enter the groove lo of the web and exert pressure against the rail at the ends of the chair. The overlapping portions of the wedge members create a greater binding action as they contact with each web and the rail shallow portion of the groove 15.

The wedge members 16 are each provided 2 with a lug 19 formed withan aperture 19 disposed to aline with the aperture of the adjacent lateral extension 14 when the driven into place. A threaded bolt 20 is apertures in the lug and extension, the head 21 of the bolt contacting with the lug, there being a pin 22 inserted through the bolt adjacent the extension 14 whereby it is supported against displacement. noted by this construction members after having been will be effectually locked against movement relative to the chair, regardless of the wedging connection of the members with the chair and rail.

that the wedge driven into place at the i inserted through the It :will be The many advantages of a construction of this character will be clearly apparent, as it will be noted that the device provides a simple and effective locking mechanism for the meeting ends of rails in which the locking members are maintained against displacement by their binding action with the rails, there being an auxiliary locking mechanism provided for holding said members in contact with the rails.

It will also be noted that the entire structure' is such as may be easily and economically manufactured, and that the various parts may be readily assembled.

What I claim is:

1. A rail joint comprising a chair which includes a base and longitudinally extending webs, the inner face of one of thewebs belng formed'with a groove which is ta- H 7 ing groove which is curved '7 15 pered adjacent the terminals of the web,

and wedges disposed to enter the groove from opposite ends, the wedges overlapping and contacting with the meeting ends of the rails which are received" between the webs,

2; A'railjoint comprising a chair whi'ch includes ab-ase and longitudinally extending webs between which the meeting ends of therails arereceived, one of the webs being. formed with a longitudinally extend- I w transversely aoent I the deeper adjacent said'ends than at its central portion, wedge members flattened adj acent their smaller terminals and rounded Copies of this patent may 'be obtains adjacent their l-argerterminals, said wedge the groove of theweb members entering from opposlte ends, and means for locklng said wedge members to the chair.

3. A rail joint comprising a chair which ends of the web andwhich is adjacent their larger terminals, the wedge members entering the groove from opposite ends, said wedge members being provided with extensions, and bolts passing through said extensions and means formed integral w-i'th'the chair, whereby the wedge members are supported against movement with respect to the chair.

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