FISH-PLATE AND RAlL-FASTEN ER.

SPECIFICATION forming part of Letters Patent N 0. 737,942, dated September 1, 1903.

Application filed March 28, 1903.

To all whom it may concern:

Be it known that 1, WILLIAM H. LOGAN, a citizen of the United States of America, residing at Carnegie, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Fish- Plates and Rail-Fasteners, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in fish-plates for railroad-rails; and the main object of the invention is to construct a fish-plate to embrace the rail, fitting underneath the tread thereof and the base at the upper edge of the latter and embracing the base, the flange of the plate having a struck-out lug adapted to rest upon the cross-tie and be securely spiked thereto.

A further object of the invention is to construct a device of this character which will securely hold the rails against lateral movement without the aid of bolts passing through the webs of the rails and. the fish-plates.

Briefly described, the invention comprises an integral plate and a clamp member which receives one-half of the rail-base, the base of this clamp member being cut out at one or more points and the portion thereof bent on twardly to form a brace-plate adapted to lie upon the cross tie and be rigidly spiked thereto. Where the joint between the rails is between two of the cross-ties, the device will be provided with a lug for engagement with and be secured to the ties at each side of the joint, and where the joint is to be placed directly upon one of the cross-ties a single brace-plate may be employed.

The invention will be hereinafter more specifically described and then particularly pointed out in the accompanying claims; and in describing the invention in detail reference will be had to the accompanying draw- .ings, wherein like numerals of reference will be employed for designating like parts throughout the difierent views, in which Figure 1 is a detail perspective view showing my improved device in position, the joint being made between two adjacent cross-ties, one of the rails being in cross-section and the other broken away. Fig. 2 is an end View of one of the fish-plates. Fig. 3 is a side eleva- Serial No. 149,927. (No model.)

tion of the same, and Fig. 4 is an underneath plan view thereof.

My invention comprises both a fish-plate and a chair to receive the ends of the rails.

In practice where the joint is to be laid between two ties, which is a common practice, the device will be made of a sufficient length to permit of the forming of two securing-plates thereon, one for each of the ties at the sides of the joint, and where the joint is to be made on top of one of the ties a single securingplate will be employed. In Fig. 1 the device is shown with the joint laid between two adjacent ties 1, while the device, as shown in Figs. 3 and 4, is adapted to be employed when the joint is madeon top or over a crosstie.

My invention embodies a fish-plate 2, preferably constructed of the standard formthat is, to engage underneath the tread of the rails 3 and at the upper edge of the base, whereby the weight on the treads of the rails is delivered to the fish plate. This fish-plate is formed integral with a base-receiving clamp member which receives practically one-half of the rail-base. This clamp member embodies the upper plate 4 and a base-plate 5, the former shaped to conform to the upper face of the rail-base, and the baseplate being formed with a flat upper and lower face, whereby to receive the flat face of the rail-base and also to rest fiat upon the crossties. The base-plate 5 is formed intermediate its ends with parallel slits extending throughout the width of the plate, and the material between these slits is struck or bent outwardly to form a securing-plate 6,adapted to rest upon the cross-ties and be securely spiked thereto, as shown at 7. Where the joint is over a tie, one plate only at each side will be needed; but where the joint is laid between the ties a securing-plate for each tie at the side of the joint will be employed. The base-plates 5 are preferably made slightly less in width than one-half the width of the rail-base in order to allow for expansion and contraction. The securing-plates act as a brace for holding the fish-plates firmly in position against the rails without other securing means than the fastening employed in the plates, though, if desired, spikes may be engaged with the edge of the clamp member.

the material between said slits struck out wardly with its lower face on a plane with the tie with apertures formed in said extensions for securing the same to the tie, substantially as described. 7

In testimony whereof I affix my signature in the presence of two witnesses.

WILLIAM H. LOGAN.
