To all whom it ma y concern.' l Be it known that I, HERBERT P. ELLER- BECK, a subject of the King of Great Britain, residing at Carlton, in the county of Carlton and State of M'mnesota, have invented certain new and useful Improvements in Rail- Chairs; and I do hereby declare the following to be a full, clear, andexact description of the invent-ion, such as will enable others skilled in the art to which it appertains to make and use the same. My invention relates to rail chairs for railway rails and has for its object the provision of means forpreventing the rail from creeping longitudinally. v

With this and other objects in view, it consists of the constructions, combinations and arrangements of parts hereinafter described and claimed.

In the drawings, Figure 1, is a perspective view of the preferred form of my invention. Fig. 2, is a similar view of the lower plate thereof. Fig. 3, is a similar view-of the upper plate thereof. Fig. 4, is a fragmentary perspective view of a modified form of my invention. Fig. 5, is a plan view of said invention showing the plates in artly retracted position. Fig. 6, is a vertica transverse section on the line A-B of Fig. 1, showing the rail mounted on the chair, and a supporting cross tie. Fig. 7, is a vertical transverse view of said invention ap )roximately similar to Fig. 1, but showing t e upper and lower plates in retracted position, and omitting the tie.

l In the drawings, 1, is a base plate having depending flanges or teeth 1a adapted to b1te into the cross tie 2 and prevent horizontal movement of said plate. Said plate has formed thereon or secured thereto upon the upper face t-hereof, a shoulder 1b upon which is formed or secured a shoulder 1c which shoulder 1c preferably has formed thereon an over-hanging lip ldadapted to overhang one of the flanges 3 cf a. railway rail 3. Extending into sa1d shoulder 1C are one or more keys or pins 4 having an exposed edge as 4 adapted to bite into said flange. A spike passage 1e is formed in said plate preferably at one side of said shoulders 1? and 1c and a second spike passage 1b is formed in said plate preferably near the opposite end thereof andA diagonally opposite `to the first said spike passage. In said drawings, 5 is an upper plate indented or cut away at one corner as at 5 to receive the shoulder lb of said lower Specification of Letters Patent.

plate, upon whichA lower pla-te said Aupper plate is adapted to be mounted. Formedon` or secured to said upper plate is a shoulderyb preferably diagonally opposite to said shoulf 60.

der 1. Said shoulder 5b is preferabl pro vided with an overhangmg tongue ,Sca apted` to overhang the opposite flange of sa1d rail.

Said upper plate is provided with spike passa proximately register with the spike passages v in said lower plate. One or more ins or keys 5e extend into said shoulder 5 said keys having exposed edges, as 5f, adapted to bite into said opposite flange of said rail.

Spikes 6 extend through said spike passages into the tie 2. If desired, the overhanging tongues on said shoulders 1c and 5b, as is indicated in Fig. 4, may be omitted.

In operation said plate l is slipped under the flange of the .rail from one side and the plate 5 is slipped under said lflange from the opposite side and above said plate 1, the keys in said shoulders beingl first preferably lng into contact with the edges of the rail flanges as said plates are slipped under the rail. The spike passages of the upper plate are not at such time wholly in registration with the corresponding passages of the lower plates, and the keys do not yet bite into the rail flanges. U on inserting the points of the spikes and riving the spikes home, the plates are drawn farther together by the their passage through the upper and lower spike passages, and the keys may thus be caused to bite into thevrail flanges, thus preverting creeping of the rails. The weightof passing trains will force the flanges 1a down into the tie. If the over-hanging tongues on said shoulders are omit-ted, as may be, the spike passages are so placed, as shown in Fig. 5, that the lips of the spike headswill overhang the flanges of the mils.

It is obvious that said invention may be further modified within the scope of certain of my claims, and especially so with respect to the form of said keys and ith respect to their position in said shoulders.

What I claim is:

1. In a rail chair, the combination of two ges 5d adapted in operative position to ap- 65X other of said plates being provided with a shoulder adapted to extend upwardly at the other side of said ilange, keys extending into said shoulders and adapted in operative position to bite into said llange,4 and means adapted to secure said plates to a railway cross tie.

2. In a railway chair, the combination of two overlapping plates, one of said plates being provided with a shoulder adapt-ed to engage the llange of a railway rail at one side V thereofI the other o said plates being provided with a shoulder adapted to engage the
