To all whom t may concern.'

Be it known that I, DANIEL L. BRAINE, a citizen of the United States, residing at New York city, in the county of New York and State of N ew York, have invented certain new and useful Improvements in Rail Supporting and Fastening Devices, of which the following is a specification.

This invention relates to improvements in rail supporting and fastening devices, and has for its object to provide such a device by means of which a rail may be readily secured in place, or removed therefrom, without necessitating the complete removal of the securing spikes, as is necessary in the present-day practice.

Another object is to provide an improved form of tie-plate, which may be readily and cheaply stamped, or similarly formed, from metal.

Still another object is to provide an improved screw spike, adapted to co-act with such frame, to maintain a rail in position as the same wears down upon its supporting block, capable of adjustment and following the base of said rail downwardly, and continuing' to maintain the same in position.

Still another object is to provide a spike which, in addition to performing the above functions will co-act with a tie-plate, so as to provide a supporting or reinforcing means for the head of the spike, to prevent bending or outward turning of the latter.

Other objects will be made apparent and set forth in the following specification and accompanying drawings, in which- Figure 1 is a side elevation of my combined device, showing the rail in section; F ig. 2 is a plan view of the construction shown in Fig. 1, one of the spikes being removed, and one of the spikes being in position to permit the removal of the rail; Fig. 3 is an end elevation of my device; Fig. 4 is a detail section showing the spike in original holding position; Fig. 5 is a similar view, showing a spike rotated to follow the rail down, after the latter has worn down the suppo-rting block; Fig. 6 is a perspective view of the tie-plate, or metal frame, as T term it; Fig. .7 is a perspective of the supporting block; Fig. 8 is an inverted plan view of the head of the spike; and Fig. 9 is a perspective of the same.

or frame, 14, comprising the top portions 14a, spaced apart a distance substantially equal to t-he width of the rail-base, 11, and the sides 14", is adapted to rest on the supporting block 12, the sides 14b closely fitting the sides of the block and terminating short of the upper surface of the tie, 13. The sides, 14h, are preferably cut away between the top portions 14a and 14", as indicated by numeral 14. As shown in Fig. 1, this will prevent the weight of the rail or passing train being transmitted to any part of the metal frame, 14, the supporting block, 12, receiving the entire direct weight, and consequent crushing force.

Provided in each of the top portions, 14a, are the spiking apertures 14. These apertures may be stamped or punched from the metal, and are shown as opening into t-he space between the respective top portions. The peripheries 14d of the apertures are oftset as shown in Fig. G, thereby forming in each periphery a shoulder designated by the numerals 14e, respectively. This shoulder is located, in each instance, at approximately the mid-point of the periphery surrounding the corresponding spiking apertures, as is clearly shown in the drawings, for a purpose hereinafter described.

The supporting` block, 12, will be provided with drilled-out spiking holes, 12a, located to aline with the corresponding opening of the spiking apertures in the metal frame, 14. Coacting with the block and frame is the screwspike, 20, having the threaded stem, 20a, (see Figs. 4 and 5), and the circular head, 20", from which projects outwardly the upper non-circular head, 20c, adapted to be engaged by a wrench, or etc., for rotation of the spike. This head, 20", is provided with the helical under surface, 20d, of inclination reverse to that of the screw thread of the stem, 20a, z'. e., where the thread of the stem is right-handed, as shown in this instance, the helix of the under side 20d of the screwihead 20b is left-handed. The head 20b is further provided with the cutaway portion 20e, preferably cut away in a plane parallel to the axis of the stem, 20a.

lWhat I term a supporting shoulder, 20f, is formed on the under side of the head 20h, and extends partially around the stem 20a of the spike 20, as is shown clearly in Figs. 8 and 9. This shoulder 20E is also provided with the heli'cally inclined under side, the helix thereof being of a pitch approximately equal to that of the screw thread. This supporting shoulder', 20E, terminates-atone end, at 20g, and at its other extremity originates flush with the under surface, 20d of the head 20,` said under surface being cut away as indicated by numeral 20h in Fig.v 8. The extremity 20g of the shoulder, 205, in the construction shown, is located a slight distance'forwardly of the cut-away portion 20e of the head 20, relative to the direction of rotationof the screw spike.

Ilhef device when assembled is utilized as follows: 'Ihe position of the rail with respect tol gage, etc., is determined, and the supporting` block 12 is placed beneath the base of the rail, uponthe tie, 13.` The metal frame, 14, is also fitted in place, the base, 11, o'fi the rail, being located between the top portions 14a, as shown in Figs. 1 and 2. rIhe screw spike, 20, is then screwed down through the spiking apertures into the tie 13, ini the position indicated byv spike A, Fig. 2,.with the cut-away portion 20e parallel with the base of the rail. Vhen all the spikes are in thisposition, the rail may be readily placed or removed, as will be obvious. The spike is then rotated', clockwise, in this instance, until the' head thereoff approximatesthe posit-ion of the spike shown in Fig. Lhat which point a portion of the head 20b will project over and pressdown upon the base 11 of the rail, 10. AsV

the rail wears down upon the supporting block 12, as indicated inV Fig. 5, the spike 20:' may bescrewedlin accordingly, the head, 20"', followinglthe' base, 11, of the rail, 10, down-- wardly When in initial holding position, asfindicatedv in Fig. 11, the extremity, 20g, off the supportingshoulder 20t will be adjacent the offset edgeor sl'ioulder, 14C@ as the case may be, and as the spike isscrewed downwardly, the supporting shoulder 20fk will ride over the said edge, being inv constant contact therewith, owing to' the similarity in pitchl of the thread" ofthe spike and' the supporting shoulder, 20f. Contact of this shoulder 20f withthe edge of' 14e' serves to form a support for the head',so that outward bend ing or turning of the head of the spike,- due to lifting or turning of therail, will be preventedl It will be apparent that the spike is sov constructed that the same may be rotated approximately three-quarters of a revolution from what I term the initial holding position, as shown in Fig. 4, before the final holding position or adjusted position is reached, at which point it is advisable to change the supporting block', owingfto the amount of wear thereon.

Reverse inclination of the helical under Vside 20rl of head 20 will enable theY head of the spike to ride up over the rait-basev 1'1,

the latter being" generally of greater thickness than the metal frame, 14k. Furthermore, this reverse inclination enables a greater amount ofy take-up ofy the rail wear, for a slight rotation of the screw spike, since not only the downward. movement of the head, owing.v tothe rotation ofl the screw-thread, will actuate to draw the head down againstthe rail-base 11, but also this reverse' inclination will. cause an additive downward thrust by the screw spike head on the base ofthe rail. rIhe supporting shoulder, 20i, is constructed to clear the outer edge of the railV base, 11,. as will be apparent.

1When it is desired to remove the rail, or replace the same, it is merely necessary to rotate the spike to a position correspondingk to that of spike A', Fig; 2-w-hen the rail may be removed bodily without necessitating: the removal of the'supporting block or` metal frame from the tie.

It will be apparent that I have provided a form of devicewhich willE enable ready adjustment as the rail wears down upon itssupporting block, and in which apoint of support or reinforcement against outward turning of the screw-spike head is always maintained'.

While IA have shown and described my device with more or lessparticularity, I do not wish to be unduly' restricted to such showing or description, beyond the scope of. the appendedL claims.

What I claim is:

1.. In combination, a rail supporting means,l a frame having a topportion adapted to rest onfsaid means and said top portionz being provided: with an aperture and a reinforcing; means, a screw spike adapted to be inserted through said aperture andv screwed down togsecurea'v rail base in position, saidy spike beingprovidedl with .meansy to coact with said reinforcing; means when in' secured position to reinforce said spike against bending, saidv means-5 being con- :,structed to permit further screwing. down Y with respect to said rail base, said means and said shoulder being constructed to permit further screwing down of said vspike when said rail base is lowered, at the same time maintaining said reinforcement.
