ANTLRAIL-CREEPING DEVICE.

Application filed August 6, 1928i Serial 'No; 297,667.

My'invention relates to improvements in. anti-rail-creeping devices, and the object of the invention is to provide a device which will reduce to a minimum the creeping of rails on rail road tracks, and in the following specification and the drawings forming part thereof, I shall. describe and illustrate my invention, and a modification thereof, and what I claim as new will be set forth in the claims forming part of this specification. I:

Fig.1 is a plan view of the device; and Fig. 2 a front elevation thereof. Fig. 3 is a side elevation of the device showingit attached to a rail and secured to a sleeper.

Fig. 4 is a view similar to Fig. 3 showing a slight modification and one of a -pair of locks, and Fig. 5 1s a detail showing portion of the device and corrugated surface on the unders de of the bottom flange of the rail. V g V In the drawings, like chariicte 's of refei; once refer to the same parts. c e

At the outsetit must be understood that 1 although I have illustrated and described forn'ied with the said bottom bar" and con--.

nected therewith each by a loop l, are inward-upward cinivergin sections 5, spaced apart and substantially in alignment, and

i connected, with each section 5 by a bend 6 is a downward longitudinally-extending section 7. Each section 7 terminates in at end stantially vertically-disposed loop 8. 9 are substantially vertically-disposed loops which are connected each with a loop 8 by a section 10, and extending from each'loop 9' is a section 11, the inner ends 12 of which diverge and terminate in eyes 13'.

The device is slipped on to the rail at one end, and before it has been fastened to a sleeper, the sections. 11 occupy substantially the dotted position shown in Fig. 3.

said flange.

In this position the bar 2 lightly rests against the underside of the flange 3, and each loop 8 rests against the upper side of rail is located between the pairs of

loops

8 and 9, as will be understood. lVhen the eyes 13 are pressed into contact with a sleeper l5, and secured in this position by any suitable spike or other fastening means 16, the loops 8 in contact with the flange 3 will force the bottom bar 2 into engagement with the underside ofthe flange 8, and therefore since the said flange at each side of the rail will be pinched in three distinct areas or points, and since the device is attached to a sleeper, the device Wlll operate to offer resistance to the longitudinal and lateral movement of the rail over said The diverging ends 12 of the sections 11 are shaped as to avoid-contact with the flange 3.

In Fig.4 I show a modification more par.- ticularly as regards the shape of the sections 11, and show a lock 17 in the form of a wedge which may be inserted between the top flange or head 18 of the rail, and the sections 11. The underside of this lock 17 will be concaved to embrace the sections 11, and the contacting surfaces of said lock. and sec tions may be corrugated or otherwise roughened to prevent displacement of said lock,

There are of course two of these locks 17, and they are forced into position after the device has been spiked or otherwise secured to the sleeper. Therefore the said locks will positively prevent the withdrawal of the spikes 16, through any lifting action of the eyes 13;

To additionally couple the device to a rail or other element to be held against movement, the underside of the flange 3 may be corrugated as shown at 3, and these corrugations may be of such size as to receive the bottom bar 2. I

The locks 17 areeasily placed and re- The vertical flange 14E of the moved, and the careful use thereof will increase the frictional contact of the device with a rail.

While I have formed my device by bending it, I do not confine myself to any particular way of making the device.

The

loops

8 and 9 are resilient portions of the device, and when the device has been secured in position, its construction is such that the transverse bar 2 will be held with much force in contact with .the flange 3.

Changes in form or design will readily suggest themselves to one skilled in the art, without departing from the spirit of my inv'ention.

What I claim as my invention is:

1. An anti-rail-creeping device, embracing a transverse bottom bar adapted to rest in contact with the underside of the bottom flange of a rail, and with each end of which is connected an inward-upward extending transverse section, the said sections being spaced above said bar; a longitudinally-disposed loop connected with each oil the said sections and located one at each side of the vertical flange of a rail, and adapted to rest in contact with the top side of said bottom flange; a lever section connected with each o't the said loops, and means whereby each of the said lever sections is coupled to a fixed support therefor pinching the bottom flange of said rail between said loops and said transverse bar.

2. In a device as set forth in claim' 1, the provisionot' diverging ends for said lever sections, which diverging ends terminate in eyes to receive a suitable fastening means.

3. In a device as set forth in claim 1, the provision of additional longitudinal loops extending forwardly of the first-mentioned loops so as to increase the leverage of said lever sections.

4:. In a device as set forth in claim 1, the combination of a lock in the form of a wedge adapted to be positioned between each 01. the said lever sections and itihe .top flange of a rail.

An anti-'rail-crecping device, embracing a transverse bottom bar adapted to rest in contact'with the underside of the bottom flange of a rail, and with each end of which is connected a longitudinally-disposed vertical loop located above same and one at each side of the vertical flange of the rail, and adapted to rest in contact with the top side of said bottom flange, and a lever section connected with each of the said loops and adapted to be attached to a fixed SUP- port for said rail so as to cause said bar to be held tightly against said bottom flange.

6. An anti-rail-creeping device having two main portions located at opposite sides of -a rail, each embracing an inward-upward-extending transverse section adapted to func tion over the top side oil the bottom flange of the rail; .a longitudinally-(lisposed "loop connected with each of the said sections and located at each side of the vertical flange of the rail, and adapted to rest in contact With the top side of said "bottom flange; alever section connected With each of the said loops; means extending underneath the bottom flange whereby said transverse sections are functionally associated, and means whereby each of the said lever sections is coupled to a fixed support therefor thereby pinching the said bottom flange between said means and said loops.
