RAIL CHAIR.

Application filed October 26, 1922. Serial No. 597,198. i

. California, have invented certain new and useful Improvements, in Rail Chairs; and we 'do declare the following to be a full,

clear, and exact description of the inven-.

tion, such as will enable others skilled in the art towhich it appertains to make and use the same. I c I This invention relates generally to rail chairs, but particularly to rail fastening devices for rail chairs and is an im rovement upon the device disclosed in No. 1,402,."60, granted on January 10, 1922 to the present inventors.

The device disclosed by the aforesaid pat ent consists of a rail supporting member provided with a pair 'of vertical openings in which are disposed expansible rail spike clamps. These clamps are provided with eccentrically disposed spike-receiving openings and are reversible in the openings of the supporting member, but are not invertible so that they have to be inserted in the openings of the supporting member with certain of their ends uppermost, and consequently in order for the device to be i used, the supporting member must be placed so as to have one of its sides uppermost.

The present invention is an improvement upon the above described device, because the rail supporting member may be used with either of its sides uppermost and the spikereceiving clamps are not only reversible in the openings in said member but are also invertible so that they may be inserted with either of their ends uppermost.

The improvements forming the subject matter of the present invention render the device as a whole extremely simple, cheap and durable in construction, and the patentable novelty in the improved device resides in the unique combination and arrangement of parts and the various details of construction which are hereinafter fully described and claimed and illustrated in a atent practicalembodiment in the accompanying drawing.

In the accompanying drawing, which forms a part of this specification and throughout which similar reference characters are used to designate corresponding parts a v Fig. 1 is a side elevation, partlybroken away and in section, of a rail chair in which the improvements forming the subject matter of the. embodied; 1

V Fig. 2 is a top plan view, partly broken away and in section, of the improved rail chair. c 4 Fig. 3 is a perspective view, with a por tion broken away, of the rail chairiproper or the rail supporting member. Figs. 4 and 6 are side elevations of the complementary parts: of one ofthe rail spike-receiving clamps; and

Figs. 5 and 7 are top plan or end views of the complementary parts of. the rail present invention are spike-receiving clamp illustrated in Figs. 4

and .6 respectively.

In the drawing above briefly described, the numeral 1 designates as a whole arailsupporting member. This is preferably of the I-beam type having parallel flanges 2 and3 integrally connected by a web 4. Insofar as the improvements forming the sub ject matter of the present invention are concerned, the rail-supporting member 1 does not have :to be of the I-beam type,.but it can be of anyother type that is desired.

The rail-supporting member 1 is pro vided with a pair of spaced openings which extend vertically. therethrough from one'side thereof; to its other side. When the mem ber l is of the I-beam type, such as illustrated in the drawing, these vertical openings are formed by means of alined sub stantially H-shaped openings 5 in 'the flanges 2 and' 3 and openings or slots 6 in the Web 4;, the openings or slots 6 communicating at their ends with the alined openings 5 in the flanges 2' and 3.

The opposite edges of the openings or slots 6 are provided with concaved portions sections of the clamps are fitted together their cross-sectional contour is of substantially H-shape, corresponding with the shape of the openings 5.

In. Figsst and5 of the drawing, the numeral 8 designates one of the sections or parts of one of the, rail spike-receiving clamps and in Figs. 6 and 7 the complementary section of the clamp is designated by the numeral 9. i From these views, it will be seen that the l-l-shape contour of the clamp is formed by providing channels in theside' edges of the sections Sand 9, these channels 10 being designed to receive the edges of-the slots or openings 6 in the web 4 of the rail-supporting member 1. The channels 1030f both sections 8 and are of the same depth.

The inner sides of the sections 8 and 9, are also'provi'ded with channels 11. These channels 11 are arranged in opposing relation to eachother so that they form passages '12 extending vertically through the clamp from one end thereof to the other.

These passages 12 are disposed eccentri ca'lly withrespect to the central axes of the clamps, since the channels 11 in the clamp sections 9 are'deeper than the channels 11 in the sections 8. The channels 12 are designed to receive the spikeswhich anchor a rail *tothe supporting member 1 and therefore in order toprovide a means whereby the spikes may be held in place when once driven in 'said pass'ages, the latter at their opposite ends are provided with bends 13 whichareformed by curved projections 14 located in the channels ll'of'one section and oppositely disposed depressions 15 in the ,7 channels 11 of" the other section. This con struction causes the spikes when driven into thepassages 12 to'be bent to fit the projectionsll and depressions 15.

Formed upon the sections 8 and 9 of the rail spike-receiving clamps and "located within the channels 10 of said sections are projections 16'. These projections 16 are disposed midway between the opposite ends of thejsections 8 and 9 and are intended to fit in thenotches 7 formed, in the edges of the slots'or openings 6 of the web 4 of-the rail supporting'member 1. In using devices constructed as described in the foregoing, a number of the rail chairs vertible. spike-receiving clamps should therr be in vare secured to a wooden or concrete tie or imbedded in a roadbed in a steel tie in any suitable manner. In arranging the supporting members 1 inplace upon the ties or the roadbed, they may be placed with either side uppermost since they are in- The two-part; orv two-section serted, when in contracted condition, into the ert al pen ngs in, t e na l s pport members 1. In inserting the clamps in the openings in the rail supporting members 1, they may be placed with either of their ends uppermost "since they are invertible in said openings, but since the passages 12 extending therethrough are eccentrically disposed, the clamps should be insertedin the openingsin the supporting members so that said passages 12 will be [in proper positions to receive the spikes bywhich a rail is fastened to the members: '1.*'A fter the clainpsare in place, and the rail, s u'ch as deslgnated by the letterR in Fig." 1,"is

placed upon the members l,"spikes S-shoul'd be driven into the passages 12. When't'he spikes S are driven into the passages 12 0f the clamps, the sections 8 and 9 thereofwill be expanded and: the projections 16 will be inserted into the notches? in such a manner that the clamps will be locked in place in the openings through the member 1*a'nd cannot be moved therefrom until after the spikes S are withdrawn "from the passages'12. i

From the foregoing description,taken in connection with the accompanying drawing; the construction, use and operation of-the device will be readily understood without requiring a more extended: explanation:

It is obvious that certain changesinform,

proportion, and in the various detailsof construction, may be made without sacrifie mg any of the advantages or," departing from the principleof the inventionfan d it is therefore to be understood that; such changes may be madewithin the meaning and scope of the appended claims;

l/Vhat i'sclaimed is: 1 i 1. In a rail chair, the combinationofarailsupporting member having an openingextending vertically therethrough, an expansible, invertible, rail' spike-receiving clamp disposed in said opening, and interee'ngag ing elements carried by said member and said clamp for. locking the latteriin said 5 1 opening when in expanded position, "said elements being positloned' upon sal'd memher and said clamp so that the latterniay be invertedin said opening.-

2. In a rail'chair, the combination' o f a rail-supporting member having opening extending vertically therethrough, 'tli op posite edges of said opening being-provided with opposed notches, said notche's'being located midway of the ends of said opening, ends of'said clamp so that the latter may an expansible, invertible rail spike-receivbe inverted in said opening. ing clamp disposed in said opening, the opposite edges of said clamp being provided 5 with projections adapted to fit into said notches when said clamp is expanded, said WILLIAM R. GORRELL. projections being located midway of the HENRY BARKSCHAT.
