ADOLPHUS BONZANO, OF PHILADELPHIA, PENNSYLVANIA.

RAIL-JOINT.

SPECIFICATION forming part of Letters Patent No. 788,995, dated May 2, 1905.

Application filed February 3, 1905. Serial No. 244,007.

T0 at whom, it may concern:

Be it known that I, ADoLPHUs BONZANO, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Rail-Joints, of which the following is a specification.

'My invention relates to certain improvements in the rail-joint for which Letters Patent were granted to me on the 9th day of February, 1897, No. 576,943.

The object of my present invention is to reduce the bearing of the plate upon the ties without materially diminishing the strength of the lower truss member and at the same time allow for the slotting of the feet of the plate, so that the spikes can be driven close to the edges of the base-flanges of the rail. This object I attain in theffollowing manner, reference being had to the accompanying drawings, in which Figure 1 is a perspective view of one of my improved joint-plates. Fig. 2 is a plan view showing the abutting rails coupled by my improved joint-plates. Fig. 3 is a transverse sectional view on the line 3 3, Fig. 2. Fig.- 4 is a transverse sectional view on the line 4 4, Fig. 2; and Fig. 5 is a view of a modification.

B B are the abutting rails, and the joint is made, us usual, ata point between the tiesA A.

D D are the splice-plates, each plate consisting of an upper chord d and alower chord (Z. At each end ofeach plate are feet d which preferably rest upon the ties A. Web members (Z connect the feet with the lower chord d. In some instances tie-plates may be used, in which case the feet d may rest upon the tie-plates; but the feet of my improved splice-plates are of such a width that i in most instances tie-plates are unnecessary.

The upper chord (Z is in the form of a fishplate fitting snugly between the head and the base-flange of the rail and preferably conforms to the shape of the base-flange. In the upperchord are the holes for the passage of the ordinary securing-bolts C.

The lower chord depends from the inclined section of the upper chord, preferably in a vertical line, and the webs in this instance project at right angles to the body of the lower chord.

In my former patent the feet of the jointplates were the full width of the webs 6 but in order to reduce the bearing of the feet upon the ties, so that it will not be necessary to specially prepare the ties for the reception of the plates, I reduce the width of the feet in the present instance by cutting each foot on an angle from the end of the web (Z to the line where the upper chord joins the lower chord and then I slot each foot at f and extend the slot to a point slightly beyond the edge of the base-flange of the rails, so that spikes can be driven through the slots into the ties in such a manner as to bear against the edges of the base-flanges of the rails. By this construction I retain the full advantage of the bracing of the lower chord by the webs W. In some instances I form holes 2' in the wide portion of one or both feet for the reception of spikes when additional fastenings are desired.

When the joint is made from rolled blanks, I preferably roll the plates full width, then bend the central portion to form the lower chord, and then cut the feet at the desired angle; but if the joints are made by casting they can be cast as shown in the drawings.

In some instances instead of beveling the feet, as shown in Fig. 1, the plate may be made as shown in Fig. 5, in which the full width of the web is retained and the main portions of the feet considerably reduced, leaving enough of the foot portion to brace the web and add strength to the structure.

I claim as my invention- 1. A joint-plate for railway-rails having an upper chord arranged to be secured to the webs of the rails, a lower chord projecting downwardly beyond the base-flanges of the rails, feet on each end of the plate and webs connecting'the feet with the lower chord, the feet being greater in width at the webs than at the ends of the plate, substantially as described.

2. A joint-plate for railway-rails having an upper chord arranged to be secured to the webs of the rails, a lower chord projecting downwardly beyond the base-flanges of the rails, with feet on each side of the lower chord, and webs connecting the feet with the lower chord, the greatest width of the feet being at the point where they join the webs, each foot being tapered from the web to a line Where the lower chord joins the upper chord, substantially as described.

3. A joint-plate for railway-rails having an upper chord arranged to be secured to the webs of the rails, a lower chord projecting downwardly beyond the base-flanges of the rails, feet at each end of the plate, and webs connecting the feet with the lower chord, the feet being greater in width at the webs than at the ends of the plate, said feet being slotted for the reception of spikes, substantially as described.

' 4. A joint-plate for railway-rails having an upper chord arranged to be secured to the webs of the rails, a lower chord projecting downwardly beyond the base-flanges of the rails, feet at each end of the plate, and webs connecting the feet with the lower chord, the

feet being greater in width at the webs than 1 at the ends of the plate, each foothaving a spike-hole in the wide part and a slot in the narrow part, substantially as described.

5. The combination of abutting rails, jointplates each having upper and lower chords,

one arranged on one side of the rails and the other on the opposite side of the rails, the lower chords having inclined flanges at each end and each plate having feet at each end,

said feet being greater in width where the Web In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
