SPECIFICATION formingpart of Letters Patent N 0. 1373071, dated August 25, 1903.

application filed March 31, 1903.

T0 at whom it may concern:

Beitknown that-I, HENRY J. BUBENHEIM, a citizen of the United States, residing at Pittsburg, in the county of Allegheny'and State of Pennsylvania, have invented'a new and useful Improvement in Rail-Jointsmf which: improvement the following is a specification.

This invention relates to certain new anding a part of this specification, and wherein like reference-numerals indicate like parts in the several views, and in which Figure 1 is a perspective view showingmy rail-joint applied to the ends of two rails. Fig. 2 is a cross-section on the line'2 2 ofFig. 3. Fig. 3is a cross-section OntheJine 3 3 of Fig. 2;

traction and guard rail by the same joint.

The reference-numeral 1 indicates the chair, in which the rails and securing parts are firmly held, said chair being secured to the tie by spikes, the heads of which engagethe flanges 2 2, and longitudinalmovement of said chair is prevented by lugs or ears 3 3, provided on its under sideand contacting with either side of the cross-tie. The chair 1 is recessed in its central upper side the .length of the same, and thetwo walls 4 5,

forming the sides of this recess, are cut on an angle to a vertical line, said angle running from the upper edge of said wall toward the which are-formed on an angle corresponding with'the apertures 6 and 7 7, in which they are inserted, and said apertures and lugs are of such relative lateral width that the splicebar is free to move laterally; but longitudinal movement of said barsis prevented. The

Fig. 4 is a' view of amodified form, showing a'construction for holding both the smi 150,403. (No model.)

inside of these splice-bars arealso provided with lugs 10' and 11; which when in their securing position engage suitable apertures 10 formed in the web ofthe rail forthe purposeof preventing movement ofsaid rail. Either the outside edge'of these splice-bars or'the inside surfae of the' walls of the chair are alsocut o'na slight longitudinal angle, and taper keys 12, conforming in-cross-section to the spacebetween the splice-bar and the wall of the recess in the chair, are provided, said longitudinal angle of said aperture being so formed that the keys must enter from opposite ends of the chair. In securing rails in position said chair is suitably placed and the two ends of the rail laid therein. The splicebars are then inserted, it being necessary to first cause the lugs on the under side of said ertures are formed. The splice-bars are then movedtoward the .web of the rail, thekeys 12 inserted and driven home, thus forcing said splice-bars to firmly engage, support,

and hold the rail. The angle on which lugs and apertures are out now prevent any substantial vertical movement of the rail, and

the vertical angle of the wallsof the recess in the chair'and on the outside of the splice bar prevent the vertical movement of the key. Longitudinal movement of the rail is prevented by the lugs on the inside of the splice-bar co'acting with the apertures in the web of the rail. I

A modified form of thisrail-joint is shown in' Fig. 4 and consists in adapting the fea--:

tures of this invention to the holding of a guard-rail, together with a traction-rail, and

consists of the chair 1, having the securingfianges 2 and ears 3, the keys 12 and 12'. and the splice-bars 8 and 9' are the same as in the other form, whereby only one rail is held; but a rail-separator 14, having the angular lug 15, which is inserted in the aperture 16,

formed in the chair, keeps the rails properly spaced.'

While I have described .my invention in detail, it will be noted that slightchanges may be made in the details of construction without departing from the general spirit of the same.

ICO

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a rail-joint the combination of a chair, the upper side of which is recessed, the walls of said recess being formed on alongitudinal and vertical angle, the bottom of said recess being provided with a plurality of apertures, the lateral walls of which are formed on a vertical angle, splice-bars which engage the rail at either side, said splice-bars being provided with lugs which engage apertureform ed in the web of the rail to be held, the under side of said splice-bars being provided with angular lugs which are inserted in the apertures in the said chair, the relative size of said lugs and apertures being such that the said splice-bar may have lateral but not longitudinal movement, the outside edge of said splice-bars being cut on a vertical angle corresponding With the adjacent wall of the recessin said chair and taper keys which wedge between the splice-bars and the walls of the recess of the chair, substantially as described.

2. In arail-joint the combination of a chair, the upper side of which is recessed, the walls of said recess being formed on a longitudinal and vertical angle, the bottom of said recess being provided with a plurality of apertures, the lateral walls of which are formed on a vertical angle, splice-bars which engage the rail at either side, said splice-bars being pro vided with lugs which engage aperture formed in the web of the rail to be held, the under side of said splice-bars being provided with angular lugs which are inserted in the aperturesin the said chair, the relative size of said lugs and apertures being such that the said splice-bar may have lateral but not longitudinal movement,the outside edgeofsaid splice-bars being cut on a vertical angle corresponding with its adjacent wall of the recess in said chair and taper keys which wedge between the splicebars and the walls of the recess of the chair, said chair being provided on its sides with horizontal securing-flanges and on its bottom with vertical ears, substantially as described. In testimony whereof I have hereunto signed my name in the presence of two subscribing witnesses.

HENRY J. BUBENHEIM.
