RAIL-CHAIR.-

Specification of Letters Patent. Pajtented Apr, 30, 1912.

Applieation'fil'ed April 22, 1911. Serial No. 622,767.

To all whom it may concern: I

Be it known that I, HnNRrELLior, a citizen of the United States, residing at- St. Louis, in the State of Missouri, have invented certain new and useful improve-- ments in Rail-Chairs, of which the followmg is a specification.

This invention relates to rail chairs and has for its primary object to provide an improved device of this character which can be simply and economically made, which will be durable -and etlicientin operation, and which can be easily introduced into position and removed therefrom.

One of the objects of the present invention is to provide an improved integral construction which is adapted to be inserted into position under a rail and by a simple adjusting movement made to positively grip the base flange of the rail.

Another object is to provide an improved base plate design for rail chairs whereby they are adapted to be seated securely upon the railroad tiesand whereby the process of manufacture is greatly facilitated.

Other and further objects willappear in the specification and be specifically pointed out in the appended claim, reference being had to the accompanying drawings exemplifying the invention, and in which,

Figure 1 is a fragmentary perspective view showing my improved device in operation. Fig. 2 is a topplan view of the same. Fig. 3 is a sect-ion on the line III,III, 2'. Fig. at is a bottom plan view of the rail\ chair detached. Fig. 5 'isa fragmentary top plan View of the device illustrating the relative positions of the parts for removing Referring more particularly to the drawings; the rail chair-comprises inan integral piece, a base plate 1 constructed in the man ner to be presently pointed out and provided with a pair of claws or/hooks 2 spaced from each'other both laterally and longitudinally of the rail 8.. The base plate lot the rail chair is preferably constructed ree tangular and has its undersiirface provided with projecting ribs-t of wedge-shapedfcrtiss' section extending around its .perimetral edges and other intermediate Wedge-shaped ribs 5 extending longitudinally and trans versely of the base plate and intersecting engage the base flange 7 of the rail, and.

when the rail is in position in the chair, the

def

lateral gripping Walls bf the claws 2 are" just the right distance apart to snugly grip the rail. At the same time, the spike openings '6 are arranged so that the spikes 8' which are driven therethrough impinge upon the lateral edges of the base flange 7 and thus serve to lock the rail in position by the employmentof only one spike on either side of the rail in each tie. In order to m.ake it possible to introduce the rail chair into position under the rail, the diago nal'ly iopposite claws 2 are cut away on the bias at 2-, these inclined edges being parallel'to each other and spaced apart a distance less than'the width of the base flange 7.

chair, as shown in Fig. 5., can be'shoved under the rail so asto cause one ofthe claws.2 to engage one edge of the base fiafi aafter which said base flange mav be c V leveled and the chair moved around into position, shown in Flgs. 1 and 2, in which position the base flange is securelyclatnped by the claws 2. The spikes 8 are then driven through the openings'tl into the tie, said openings 6 being preferably elongated somewhat to provide clearance way beneath the flange of the rail to permit the spikes 8v to.

be driven so as to clamp the rail flange 7.

nat I claim is:'

A rail chair comprising a base plate pro vided with projecting ribs extending around.

the perimetral edge thereof and longitudinal and transverse central ribs extending across said'baso plate between said perimetral-ribs' to divide said base plate into four sections, a pair of clamping claws stamped from the base platein diagonally opposite sections of By means of this construction, the rail said base plate, said claws heing provicled and to be shifted into clamping relation with parallel clamping Walls and having the with said base flange. outer edges thereef cut on an inclination to HEwyy I 101. said clamping walls at a distance from each L J other slightly less than the width of said in the presence ofbase flange, whereby said chair is adapted M. A. ITIALDEMAN,

to hang {r0111 the rail flange at any angle M. C. HAMMON.
