RAIL ANCHOR.

Application filed March 28,1927. Serial No. 179,083.

, The invention relates to improvements in rail anchors and an object of the invent-ion is to provide a device which will positively pre vent a track rail from creeping and which is arranged so that when installing one can readily reverse it depending'on the direction which it is found that the rail has a tendency to creep. V

,A further object is to construct the device in asimple and durable manner, so'thatrcplacements can be easily, quickly and cheaply made and such thatitin no way interferes with the customary spikes utilized to hold the rail to the tieslVith the above more important objects in view, the invention consists essentially in the arrangement and construction 'ot' parts hereinafter more particularly described, reference being had to the accompanying drawing, in which v Fig. l is a planview of a portion of a rail showing one of my devices provided thereon. Fig. 2 is a plan view of a portion of a rail and showing two of my devices applied thereon to prevent creeping in either direction. v I

Fig. 3 is-anenlarged detailed plan view of the device and adjoining portion oi the rail.

Fig. 4: is an inverted plan view oi the device.

Fig. 5 isa vertical sectionalview at 55 Figure 3 and looking in the direction of the applied arrow.

i Fig. 6 is a perspective view of the cover.

In the drawing like characters of reference indicatecorresponding parts in the several figures. r

The track rail 1 is carried by the tie plates 2 which are mounted on the customary ties 3.

The usual spikes 4 and 5 are employed to hold" the rail to the tie, these being driven into the tie through suitable holes provided in the plate.

Under existing traffic and other conditions,

if it is found that a .rail creeps inone direction only, such as in the direct-ion of the applied arrow Figure 1, I use one of my devices which would be located on the central'tie of those carrying the rail and would have the device set as later explained to prevent the creeping of the rail in the direction indicated Figure 1. Where a rail may creep in either direction as indicated by the applied arrow Figure 2, I will place two of my devices on the two ties nearest the centre of the rail, such as shown in Figure 2 and will set the device to prevent creeping in either direction.

As herein shown, the tie plate 2 carrying my device is in the nature of a substantially rectangular plate provided at the inner end with an upstandingstop flange 6 adapted to engage theinner edge of the rail base when the rail is in position. T he plate is provided also with pairs of spike holes 7 located in the usual position tlCljZlCGl'lb the inner and outer edges of the rail base and the customary angularly positioned spikes l and'5 are driven into the tie through the holes andhave the heads thereof overlying the base of the rail as shown.

In a location intermediately between the pair oi spike holes at the outer side of the rail, locate anupstanding stud 10 which is positioned somewhat further out from the rail base than the spike holes and is carried bythe tie plate. On this stud, I mount ro tatably a dog 11 which is provided with :1 circular hole 12 to receive the stud. The dog is designed to engage the adjacent edge of the rail base and has the engaging end thereof presenting a toothed face 13which is formed eccentric to the vertical axis of the stud. I The length of thedog is such that it will always maintain an angularlydisposed position in respect to the rail, that is to say, the longitudinal axis of the dog will not at'any time-be able'to take a position atright anglesto the longitudinal axis of the rail.

- A cover 141 is provided to enclose the greater part of the dog, the cover being made from a substantially rectangular plate having-the corners cut away as indicated. at 15 and 16 to clear the spikes and the uncut sides and outer edge fitted with a continuous downturned flange 17 Centrally the cover is provided with a built up collar 18 and an opening 19 passing therethrough which receives the upper end of the stud. The upper end of the stud is provided with a hole 20 and the a 7 upper face of the collar is fitted withradiat- 'ing slots 21. A cotter pin 22 is passed this time, the spring will be extending as shown at A in. dotted outline in Figure 3. One then applies the cover and in applying it, catches the tree end of the spring behind the flange 17 and after having caught it, retates the cover into the position shown in Figure 3. This movement will bring the spring into the position shown at B Figure 3 where it is in tension and is accordingly acting to swing the dog towards the previously inserted rail base. lVhilst one is holding the cover in the position shown, the cotter pin is passed through the slots and hole 20 and locks the coveragainst rotation.

With the device so setit will be apparent that any tendency of the rail to creep from left to right will be counteracted by the jamining action effected between the stop flange 6 and the dog.

If it is desired to prevent creeping the rail in the opposite direction to that just de scribed, the dog is put in place in the reverse 7 position as will be readily understood. The

arrangement of the anchor is such that the rail can be readily put in place on the tie plate as the cover is not applied until after the rail has been set on the plate and under such condition, the spring is inactive so that the dog can be moved out to clear the rail. Further all parts are arranged so that the spring canbe readily replaced should it fail through continued use. Another important feature is that the dog can be set to prevent creeping of the rail in either direction.

l/Vhilst- I have shown the dog as carried by a tie plate, it is to be understood that it could be mounted on the Well known type of rail anchor and will act with equal eliect to prevent end shitting or creeping oi the rail.

What I claim as my invention is 1. The combination with the base of a rail, a tie plate supporting the same, said plate be ing provided with a stop shoulder engaging one edge of the rail'base, of an upstanding stud permanently attached to the plate and positioned somewhat back from the other edge of the rail base, a dog pivotally mounted on the stud and presenting a toothed face engageable with the latter edge of the rail and formed eccentric to the stud, a cover overlying the dog, a spring extending between the cover and the dog and holding the rail base, a dog pivotally mounted on the stud and presenting a toothed lace engageable with the latter edge of the rail and formed eccentric to the stud, a cover overlying the dog and pivotally mounted on he upper end of the stud and provided with mar; ginal flange, a spring carried by the dog" and en ageable with the flange and a withdrawable locking pin fastening the cover to the stud.

3. The combination with the base of a rail, oi a tie plate supporting the rail'base and provided at the inner end with annpstanding stop shoulder engageable with one edge of the rail base and with suitably located spike holes, an upstanding stud carried by the plate in a location adjoining to but somewhat back from the other edge of the rail base, a reversible dog pivotally mounted on the stud and provided with a toothed face engage ble with the latter edge 01": the rail base and formed eccentric to the stud, a cover overlying the dog and provided with an opening to rotatably receive the upper end or" the stud and with a marginal flange, aflat spring carried by the dog and engageable with the flange and normally pressing the dog to wards the rail and a withdrawable pin tastening the cover to the stud.
