RAIL-JOINT.

Specification of Letters Patent.

Patented March 13, 1906.

Application filed June 3, 1905. Serial No- 263,673-

To aZZ whom, it may concern:

Be it known that I, JoNAH DAVIES, a citi zen of the United States, residing at Drums, in the county of Luzerne and State of Pennsylvania, have invented new and useful Improvements in Rail-Joints, of which the fol-. lowing is a specification.

This invention relates to rail-joints, and

articularly to an improved splice-bar, having for its objects to produce a comparatively simple inexpensive device of this character in which free expansion of the rails under the influence of heat and cold is permitted, one whereby the meeting ends of the rail-sections will be firmly and securely connected, and this without the formation of bolt-holes in the rail-webs and consequent weakening of the latter, and one whereby the rails will be securely fixed against relative vertical movemeint, thus to obviate pounding of the rail en s.

A further object of the invention is to provide a device of this character in which the rails may be readily assembled, one in which the rails may during the operation of assembling be brought accurately in position, and one whereby the rails will when in connected position be firmly clamped in the splicing member.

With these and other objects in view the invention comprises the novel features of construction and combination of parts more fully hereinafter described.

In the accompanying drawings, Figure 1 is a perspective view of a splice bar or member embodying the invention. Fig. 2 is a top plan view of a rail-joint, showing the splicebar in applied position. Fig. 3 is a section taken on the line 3 3 of Fig. 2.

Referring to the drawings, 1 designates a pair of rail-sections of usual construction and material and each comprising a tread, a web, and a base-flange of ordinary form, as illustrated by dotted lines in Fig. 3, these railsections being adapted for assemblage in endwise relation and to be connected by a splicing member or bar 2 and a clamping member or fish-plate 3, as more fully hereinafter explained.

The splicing bar or member 2, which is cast or otherwise formed in a single piece, comprises a base portion or plate 4, designed to seat beneath the rails, a longitudinally-extending side portion 5, adapted to bear at one side of the rail between the tread and base-flange of the latter and having an undercut face 6, forming, in conjunction with the base 4, a recess 7 to receive one side of the base-flange of the rail, there being formed at the normally inner edge of the member 2 a vertically-uprising longitudinally-extending flange 8, having at suitable spaced intervals bolt openings or perforations 9. Provided at the longitudinal center of the member 2 and preferably formed integral therewith is a bearing block or head 10 of cross-sectional form, corresponding to that of the rail and constituting an abutment for limiting the entrance of the rails into the splicing member 2 and for obviating longitudinal movement of the latter when applied for .connecting the rail-sections, there being extended through suitable alined openings 11 in the head 10 and flange 8 strengthening members or bolts 12, which serve to strengthen the side portion or flange 8 and which receive nuts 13, bearing upon the outer face of said flange, and nuts 14, adapted to bear against the clampingplate 3, through which latter the bolts 12 eX- tend when the parts are in assembled osition. The clamping member 3 is in the orm of an ordinary fish-plate of a cross-sectional shape to fit against the rail-Webs between the tread and base-flange, this plate being normally secured in place by clamping elements or bolts 15, threaded through the openin s 9.

n practice and in order to assemble the parts the bolts 12 and 15 are removed, and the rail-sections 1 enter longitudinally into the splicing member or bar 2 until they contact at their inner ends with the block 10, after which the clamping-plate 3 is placed in position and the bolts 12 inserted and secured by means of the nuts 13 and 14, which latter hold the plate 3 a ainst the side of the rail, after which the bolts 15 are entered in the openings 9 and manipulated for clamping member 3 securely in place and pressing it tightly against the rail-sections, whereby the latter are securely clamped between the plate 3 and side portion 5 of the splice-bar. It will be observed that under this construction the formation of bolt-openings through the rails is rendered unnecessary, thus obviating weakening of the rails and permitting their free expansion and contraction under the influences of climatic changes, and, further, that relative vertical movement of the rails is overcome, thus preventing pounding of the rail ends.

From the foregoing it is apparent that I produce a comparatively simple inexpensive device of this character admirably adapted for the attainment of the ends in view, it being understood that minor changes in the details of construction may be resorted to without departing from the spirit of the invention.

Having thus described the invention, what I claim is- 1. A splicing member for railway rails comprising a base portion and a pair of spaced side portions, one of said'portions being adapted to bear upon-one side of the rail, clamping elements entered through the other side portion, a clamping member adapted to bear against the other side of the rail and to be maintained in place by the clamping elements, a bearing-block provided between the ends of the splicing member, and a strengthening element extended through said block and the last-named side portion of the spring member.

2. splicing member for railway rails comprising a base portion and a pair of spaced side portions, a bearing-head provided on said member at a point between its ends, a clamping member, clamping elements engaged with one of the side portions and adapted to act upon said clamping member for maintaining the latter in clamping position, a strengthening element entered through the head and last-named side portion, and nuts tapped onto the strengthening element and designed to bear respectively against the said side portions and clamping member.

3. A splicing member for railway-rails comprising a base portion and a pair of spaced side portions, clamping-bolts threaded through one of said side portions, a clamping-plate adapted to bear upon the rails and to be acted upon by the clamping-bolts, a bearing-head provided on the splicing member at a point between the ends of the latter, a pair of strengthening-bolts entered through the head and last-named side portion.

In testimony whereof I afliX my signature in presence of two Witnesses.
