.Application led March 2S, 1911. Serial No. 617,400.

To all whom 'it may concern: y

Be it lrnown that I, WILLIAM J. MCDEP.- Mo'r'r, a citizen of. the United States7 and residing in the Borough of 'West Homestead, in the county of Allegheny and State of Pennsylvania, have invented or discovered new and useful Improvements in Railway Appliances, of v which the following is a specification.

My invention consists of new and useful improvements in railway appliances, more especially relating to splice-bars or devices for attaching together the abutting ends of rails and securing the same to the cross-.tie or other support.

Generally speaking, it consists of a sleeve member slidably mounted en the tie and provided with a splice-bar portion adapted to engage one side of the rail bases and webs, and a second. member adapted to be introduced between said irst member and the tie and also provided with a splice-.bar portion 'adapted to engage the other side of the rail bases and webs. The rail ends are clamped between said members which are themselves wedged together and to the tie.` To prevent said members from becoming loosened or moving in relation to the tie, pins are driven in holes in one of said members and the tie, which pins, by their wedging action, draw said members more closely together. The heads of said pins are preferably beveled and coact with a corresponding surface on one of said members to prevent accidental loosening of said pins.V The rails are secured to said members by means of pins engaging holes in the webs of the rails and in the said members. The holes in the rail webs are of larger diameter than those in said members and the pins are provided with anenlarged central portion to seat in said ra'il holes and smaller end diameters to seat in the holes in said members, so that when said members are in position, said pins are held in place. The method of securing said members to the tie may be used in connection with the fasteners which attach the rails to the ties intermediate of their ends.

In the accompanying drawings, Figure 1 is a side elevation, partially in section along the line I-I in Fig. 2, showing two rail ends secured together and to the tie; Fig. 2 is a Vvertical section taken along the line II-II in Fig. 1; Fig. 8 is a perspective of one of the members; Fig. 4 is a similar view of the other member, and Fig. 5 is an elevation of one of the pins.

The following is a detailed description of the drawings.

1 is the tie, shown as a metal tie of the girder or I-beam type, and 2 and 2 are the rails whose abutting ends meet above tie 1.

3 and 4 are two coacting splice-bar members. The member 3 is in the form of a sleeve having a bottom slot or opening which permits it to be slid onto the tie 1. One end ofthe member 3 is provided. with an upwardly extending splice-bar portion 5 which engages one side of the bases and webs of the rails 2-2, the member being mounted so that the portion 5 engages the inner side of the rails.

4 is the wedge member, having preferably a tapered body to increase the wedge action and adapted to be driven in between the top of the tie and the body of-member 3. The member 4 is provided with an upwardly ex tending splice-bar portion 6 which engages the outer side of the rail bases and webs.

The member 3 is first placed in position and the rail ends adjusted thereon. The member 4 is now driven into place with the portion G engaging the rails, thus wedgi'ng themembers together, into engagement with the rail ends and into close attachment to the tie.

The wedge portion of member 4 is provided withone or more holes, 7 7, and corresponding holes 8-8 are provided in the tie 1. Vhen the members 3 and 4 have been wedged into place, as described above, a par tial registration is effected between each hole 7 and the corresponding hole 8. The holes 7 7 and 8#8 are .preferably square. A pin 9 is now inserted in the holes 7 and 8. Said pins are provided with atapered or wedge-shaped lower end and a squared shank, so that the'pin may be inserted into the said holes. As the pin is driven down into the holes, the tapered or wedge-shap portion of the pin forces the member 4 't' move so that the registration between holes' 7 and 8 is completed, increasing the wedging engagement between the members 3 and .4 and more firmly clamping the sameto the rails and to the tie. 'When the holes 7 and 8 are in perfect registration, the squared shank of the pin 9 seats in said holes, thusv avoiding the tendency of the pin to be forced upwardly out of said holes as would be the .A

case Were the entire shank of the said pin tapered or wedge-shape. The heads of the pins 9 9 are beveled as at 10-10 and lit under the reversely beveled edge ll 'of the member 3, thus locking said pins in place. The pins 9-9 are 'preferably made of resilient material so that their heads may be readily forced down under the beveled edge 11 of the member 3. If desired, the Shanks of the pins 9-9 may be slotted and wedgeshape, split keys 12--12 driven in against the bottom of the top flange of the tie l, thus wedging said pins down tightly in place and preventing their accidental loosening.

The rails are secured to the splice- bar portions 5 and 6 of the members 3 and 4 by means 4of the pins l3-l3. The holes in the webs of the rails 2-2 are of larger diameter than the holes 14--14 in the members 3 and 1 andthe central portions of pins 13-13 .are o f the proper diameter to tit in the holes in said webs, while the ends of pins 13-13 are 0f reduced diameter to fit the holes 14.-14.

It is evident'that when the members 3 and 4.1 are in place, the pins 13-13 are held securely in place without the use of'nuts o1 cotter pins. v The holes 14E-14 are preferably longitudinally slotted to allow of rail eX- pansion and contraction.

The holes 7 -7 and 8-'8 and the pins 9-9 are preferably squared to give better bearing surfaces. 1 1

The arrangement of holes 7-"7 and 8-8 and pins 9--9 may be used in connection with the fasteners with which the rails intermediate of their ends are secured to the cross-t-ies or other supports.

It is evident that my device is a perfect splice-bar mechanism securely attaching the rail ends together and to the tie without the use of bolts and nuts or other expensive elements which are likely to loosen accidentally. I therefore combine in one device the splice bar and rail fastener7 and also obtain a positive anti-rail-creeper, as the rails 2-2 are capable of no longitudinal movement except that involved in the expansion and contraction of the metal."

The pin 9 is preferably provided with a head widened inV one direction and the edge f thereof beveled as at 10, so that in changing the track gage a wedge member 4 with its holes 7-7 a greaterdistance from the splicebar portion 6 may be substituted. In such case the two members 3 and 4, when in operative position, are located on the tie inside of the position shown in the drawings, and the beveled edge l0" of the pin 9 be'ars against and is locked by the beveled edge 1l of the member 3.

Although,for this sake of clearness, I have` minutely described the accompanying drawings, do not wish to limit myself thereby, butlclaim broadlyl.
