SAMUEL BOOTH KULL, 0F NEW CANAAN, CONNECTICUT,

RAIL-FASTENING.

To all whom z't may concern.'

Be it known that I, SAMUEL B. KULL, aV

citizen of the United States, and a resident of New Canaan, in the county of Fairfield and State of Connecticut, have invented a new and Improved Rail-Fastening, of which the following is a. full, clear, and exact description.

The object of the'invention is to provide a new and improved rail fastening arranged to securely tasten the rail in position on the supporting plate and to fasten theV latter in place on thevrailroad tie. Another object is to permit of unfastening thevrail whenever it is desired to remove'a worn out or detective rail for replacement by a new one or for other reasons.

In order to accomplish the desired result, use is made of a rail supporting plate forming a. rest for the base of the rail and adapted to rest on a tie, the supporting plate having converging apertures, and spikes, one for each plate aperture and adapted to be driven into the tie, the spikes and the -on driving the spike home.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters ot reference indicate corresponding parts in all the views.

Figure 1 is a sectional side elevation of the rail fastening asapplied, part of the tie being shown in elevation; y

Fig. 2 is a sectional side elevation of a portion. ofthe rail supporting plate; and

Fig. 3 is a rear side elevation ot the upper portion of the spike..

On the tie 10, ot' wood or other material. is held a supporting plate 11 on which rests the base 12 of the rail 13 to be fastened in place by spikes 14. The supporting plate 11 is provided with converging apertures having their upper ends adjacent the side edges of the rail 12 so that when the spikes are driven home the heads 17 engage the upper surface ot the rail base 12 to securely hold the rail in postionon the plate 11 and to fasten the plate 11 in position on the top of the tie 10. It will be noticed that by converging the apertures 16, the spikes 141 are convergngly driven into the tie and consequently are not liable to pull out on a Serial No. 164,741.

straight. upward pull exerted by a corresponding movement of the rail incident to releasing the rail after the same has been depressed by a loaded car passing over the rai The shank of the spike is provided .at the outer edge of the neck with a recess 19 adapted to engage a shoulder 20 by providing the outer wall of the aperture 16 with an inclined notch 21, as plainly shown in Fig. 2. In driving the spike home until the head 17 Iengages the base 12 of the rail, it is necessary for the workman to give an outward blow to the head so as to slightly bend the neck of the spike in an outward direction with a View to engage the notch 19 with the shoulder 20 thus locking the spike against upward movement. It is understood that by providing the outer wall of the plate aperture with the notch 21 the neckot the spike shank can be readily bent outward by an outwardblow on the spike head to engage the notch 19 with the shoulder 20 on the plate, as above explained. When it is desired to remove a defective rail 13 it is first necessary for the workman to strike the outer side of the head 17 of each spike to bend the shank inward andl tol thus dsengage the notch 19 from the shoulder 20, after which the spike can be pried out with the usual suitable tool, as is now common practice.

From the foregoing it will be seen that by the arrangement described the rail is Securely and quickly fastened, in position on the supporting plate 11 and-the latter is fastened to the tie and the spikes are not liable to become accidentally loose but can he `taken out whenever it is desired to dis assemble the parts tor the reasons stated.

l-laving thus described my invention, I claim as new and desire to secure by Letters Patent 1. A rail fastening. comprising a rail supporting plate forming a rest tor the base ot the rail and adapted to rest on the tie, said supporting plate having converging apertures on opposite sides ot the rail base. and spikes. one for each plate aperture and having its head engagingthe top ot the rail base` the spikes and the walls of the plate apertures lian/ing interlocking members engaging one the other at the time the head of a spike engages the hase of arail.

2. A rail fastening, comprising a rail supporting. plate having a, rest for the base of a rail and adapted to rest on the tie, the supporting plate having converging apertures 5 each provided in its outer wall with a retaining shoulder, and plate aperture and ea ikes, one for each provided with a notch adapted to engage the said retaining shoulder at the time the head of the spike engages the rail base and the head is forced 10 outward to bend the neck of the spike in an outward direction.
