ANGLE-BAR.

Specification of Letters Patent.

Patented Jan. 27, 1914.

Application filed June 21, 1913. Serial No. 775,052.

form one member of a splice or rail joint connection and formed to provide a wedging surface for cooperation with the ends of the bolts so that in properly positioning the bar the bolts will not only beinterlocked but wedged in place, maintaining a rigid connection under all conditions.

Figure 1 is a side elevation illustrating the application of the improved angle bar. Fig. 2 is a horizontal section partlyin elevation of the same. Fig. 3 is a plan of the securing bolt used with the improved angle bar. Fig. 4 is a vertical section partly in elevation illustrating the use of the improved angle bar.

The improved angle bar comprises a strip or section 1 preferably formed on its upper and lower edges for cooperation with the tread and base flange of therails. The bar, for each bolt used to secure the rail ends in position, is formed with a longitudinally extending depression 2 opening through the outer surface and having its inner or bottom wall 3 inclined with respect to said outer surface. The side walls of the depression 2 are arranged at right angles to the outer surface of the bar, and the inner or bottom wall of said depression is formed with a longitudinally extending slot 4: of less width than that of the depression, said slot extending through the angle bar as shown. At one end the slot is enlarged or coincides with an opening 5 corresponding approximately to the diameter of the bolts used, the opening 5 being located at the maximum depth of the depression that is at the relatively inner end of the inclined bottom 3 of the depression. The slot 4 beyond the opening 5 is, as previously stated, of less width than the similar dimension of the depression 2 so that the bottom 3 of the dem-ay be termed inclined guide Ways.

pression on each side of the slot forms what The outer surface of the bar above and below the depression 2 is formed with upper and lower rlbs 6, the upper rib being preferably somewhatthicker than the lower rib. That is the ribs extend in alinement with the edges of the depression and are formed with a series of openings 6 which are arranged in vertically alined pairs and adapted to receive pins 1 1 for holding the securing bolts in their adjusted position, as will later appear.

The securing bolts 7 are of the usual headed type, and at the end formed for cooperation with the improved angle bar-are cut away on diametrically opposed lines to provide recesses 8 having upper and lower shoulders 9 and 10 If desired the headed ends of the bolts may be provided with projections 12 to cooperate with openings 18' in the splice bar on the opposite side of the rail from the improved angle bar, whereby the bolts when positioned with their projections 12 registering in the slots 13 will be properly arranged to locate the recesses 8 for the improved angle bar.

In use the bolts in applied position are engaged by the improved angle bar by passing the openings 5 of the respective depressions 2 over the ends of the bolts, so that the recesses 8 register with the walls of the slot Within the depression. The angle bar is then forced longitudinally causing the shoulders or guide ways 3 to engage the outer shoulders 10 of the recesses 8 of the bolts, and by reason of the inclined or wedged formation of said guide ways draw the bolts into a. clamping locked position. The longitudinal movement of the angle bar is continued until the bolts are securely locked whereupon auxiliary pins 14 are passed longitudinally through the particular openings 6 between the bolt in its locked position and the entrance openings 5 of the bolt. The reverse movement of the angle bar thus prevented it is to be understood that the opening immediately adjacent and in rear of the bolt 7 is used to receive the holding auxiliary pin 14.

In the use of the improved angle bar, a uniformal tight joint is provided in which the parts are held against possibility of Sep aration, the dispensing with the nuts gained through the improved construction, removing the primerause-of the loose joint-56011 nections.

What is claimed is In a rail jointuthe. ieolnbination-zwith a' shouldered securing bolt of an angle bar formed with inclined Ways to cooperate-With the shoulders of the bolts, said angle bar beingformed with a depression opening through the outer surfaeeand ha-ying an inclined inner or bottom Wall, said angle bar' being formed ,with a slot opening through the lnner side of the bar and the inclined. bottom of the depressiomsa-id slot. being 0t less Width than the similar dimension of 15 the inclined bottnni .Wall- ,ofethe depression, the terminal of the slot being enlarged to form an entrance opening, the opposing Walls of Ithebar-beyond the depression being provided with ribs formed With registering 2o openings to receive an auxiliary pin.
