PATENT OFFICE.

CALDWELL, OF MINNEAPOLIS, MINNESOTA, ASSIGNOR TO THE I-IEATI-I RAILJOINT COMPANY, OF SAME PLACE.

RAI L J O l N T SPECIFICATION forming part of Letters Patent No. 519,904, dated May 15, 1894.

Application filed January 2l, 1893. Serial No. 459,042. (No model.)

To @ZZ whom t may concern.-

Be it known that I, EDWARD P. CALDWELL, of Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Rail-Joints, of which the following is a specification.

My invention relates to rail joints or ties, and the object of the invention is to provide a combined rail or tie-plate, adapted for convenient fastening to the ties; and having an integral angle-iron and brace to be secured to the rails, in combination with a separable angle-bar engaging the opposite side thereof.

To this end my invention consists in general in the constructions and combinations, all as hereinafter described and particularly pointed out in the claim, and will be more readily understood by reference to the acoompanying drawings forming a part of this specification, in which- Figure 1 is a plan View of a rail joint em bodying my inwention, a portion thereof being shown in section. Fig. 2 is a side View of my rail-joint. Fig. 3 is a cross section on the line of Fig. 2. Fig. 4 is a cross section on the line y-'y of Fig. 2 showing the end of the rail-joint.

As shown in the drawings, 2 represents the rail or tie-plate which is formed from a blank having a projecting side which is turned up and formed into the integral angle-bar 3 of less length than the flat part of the plate. The plate is cut back and when the angle bar is turned up the ears or projections 4 are formed and provided with holes 5 to receive the rail spikes, which are driven down into the ties and engage the tops of the rail flanges. In the opposite sides of the plate I provide holes 6 and 7 for spikes, which similarly engage the rail liange or flanges. In order that four spikes may be placed on each side of the joint I punch the holes 8 in the middle part of the plate before the angle bar is turned with the result that the openings or gaps shown are made in the curled edge of the angle bar so that spikes may be driven down close to the edge of the rail plate and sinking below the surface of the angle bar engage the topof the rail-iiange or base. A further peculiarity of the angle-bar is shown in Figs. 3

and 4 where it will be seen that the outer part thereof extends inwardly in a horizontal plane, a short distance, forming quite a sharp corner l0 to engage the rail-liange andi from which point springs the inclined part of the angle-bar which is completed by the vertical part, the whole having a form resembling that of a sh plate. An ordinary fish-plate or angle-bar Il is provided on the opposite side or sides of the rail or rails and bolts l2 extend through the rail web and through both the integral angle-bar and the separable angle-bar, thereby firmly securing the rails and joint together and accurately aligning the ends of the rails. Then the joint is first placed in position the upper or vertical part of the integral bar does not ordinarily stand exactly straight but it is drawn close into the groove in the side of the rail by the tension on the bolts, the indented lower part of the angle-bar having the corner IO permitting that part to spring and adjust itself to the rail-base. A perfect tie plate and bed for the rail is thus formed, which plate is strengthened by the upwardly projecting integral angle-bar which, in asense, forms a truss, and in addition the rails are firmly and squarely held in place, the wide bearing surfaces of the plate upon the ties effectually preventing the tilting of the same.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- The combination, with a rail or tie plate whereon the rails are adapted to rest and provided with ears 4 having spike-holes, of an integral 'angle bar formed from said plate and adapted to engage the side of .the rail or rails, said integral angle-.bar provided with a cor` ner or depressed portion 10 to engage the rail-flange or flanges, and bolts for securing the anglebar to the rails, substantially as described.

In testimony whereof I have hereunto set my hand this 30th day of December, A. -D.
