JOINT-PLATE FOR RAILROAD-RAILS.

SPECIFICATION forming part of Letters Patent No. 487,078, dated November 29, 1892.

Application filed January 15, 1892. Serial No. 413,150. (No model.) I

T at whom it may concern:

Be itknown that I, EDWARD SAMUEL, a citizen of the United States, and a resident of Philadelphia, Pennsylvania, have invented Improved Joint-Plates for Railroad-Rails, of which the following is a specification.

The object of my invention is to construct a joint-plate for railway-rails which will assume the vertical downward strains on the rails at the joint and relieve the shearing strain on the bolts which hold the fish-plate in place, the use of the fish-plate in this construction being not, as is usual, to take the vertical downward strains, but to hold the rails in proper line and to prevent them elevating at the joints or tipping over or spreading outwardly.

In the accompanying drawings, Figure 1 is a side view showing the joint-plate attached to the rail, looking in the direction of the arrow', Fig. 3. Fig. 2 is a side View looking in the direction opposite that indicated by the arrow, Fig. 3. Fig. 3 is a sectional plan view on the line 1 2, Fig. 2. Fig. 4 is a transverse section on the line 3 4, Fig. 3. Fig. 5 is a transverse sectional view on the line 5 6, Fig. 3. Fig. 6 is a perspective View of two pieces of rail resting upon the joint-plate, which in turn rests upon ties or sills, the whole being held together by bolts. Fig. 7 is a detached perspective view of the joint-plate. Fig. 8 is a modification of my invention, and Fig. 9 is a View showing the application of my improved joint to a rail having abase-fiange on each side of the web.

My invention is especially applicable to a rail of the peculiar form shown in Fig. 6, which has a base-flange at one side only of the web, this form of rail being shown, described, and claimed in the application for Letters Patent filed by me December 14, 1891, Serial No. 414,937 ,but it will be understood that my improved joint-plate can be attached to other forms of rails as well.

B is the joint-plate, preferably made from angle-plate out into proper lengths, one flange of the plate being severed at m, Fig. 7, and turned from the position shown by dotted lines in said figure to the position shown in full lines, forming a brace a and a foot a at each end of the joint-plate. The abutting rails A A rest upon the base b of the plate,

the upright flange 0 extending, preferably, in contact with one side of the web of the rail, as clearly shown in Fig. 4, and being secured to the rail by bolts f. The base of the jointplate extends, preferably, beyond the basefiange of the rail and is suitably perforated at the ends to receive spikes 11, which extend over the base-flange of the rail and confine the rail at this point to the joint-plate, and suitable spikes 2" pass through openings in the feet a and, with the spikes i, confine the plate to the ties or sills. The fish-plate D is mounted on the inner sides of the rails and secured in position by bolts d, which not only pass through the rails, but through the flange c of the joint-plate. In some instances I may use clamp-boltsj for securing the base-flanges of the rails to the joint-plate, as clearly shown in the figures; but in most cases these clampbolts may be dispensed with.

It will be understood that the brace a may have a more or less extended base, according to the character of the rail and the use for which it is intended. The angle-plate can be cut and bent at different distances from each end, thereby extending or contracting the foot, as shown by dotted lines in Fig. 4.

The joint-plate need not necessarily be made from rolled angle-plate, but can be made of sheet metal cut and bentinto the desired form.

In Fig. 8 I have shown the joint-plate made from angle-plate cut to the desired length and attached to knees B, which are independent of the joint-plate and secured thereto by bolts f, which also pass through the web of the rail.

In Fig. 9 I have shown my improved jointplate secured to the ordinary T- rail, having a base-flange on each side of the web. v

One important advantage of my improved joint-plate is that it does not extend much below the base of the rail, it being strengthened by its upright flange 0, extending up alongside the web of the rail, and when the rail shown in Fig. 4 is used this upright flange is on or nearly on the vertical thrust-line.

I claim as my invention- 1. The within-described joint-plate for railway-rails, said plate having two portions at right angles to each other, one serving as a base-plate for the support of the rails and the other adapted to lie alongside the webs of the rails and to be secured thereto, with braces one piece of metal cut and bent into form,

substantially as specified.

3. The combination of the abutting rails, the fish-plate secured to the webs of the rails on one side, a joint-plate longer than the fishplate and having a rail-supporting base portion and a portion at right angles thereto secured to the webs of the rails on the opposite sides from the fish-plate, and devices for se-' curing said joint-plate to the rails at points beyond the ends of the fish-plate, substantially as specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

EDWARD SAMUEL.
