IMPROVED RAILWAY STOP-CHAIR.

The Schedule referred to in these Letters Patent and making part of the name.

'-Tocll when?l 'it may concern:

' Be it known that I, JOHN A. WILSON, of Altoona, in the county of Blair, and State of Pennsylvania, have -invented a Stop-Chair for Railroads; andI do hereby declare thatv the following is a full, clear, and exact description thereof, reference being had to the accompanylilng drawings, making part of this specication, in whic- Figure Lis a side elevation of portions of i two sections of railroad-rails united by fish-bars and bolts, and haring one of my improved stop-chairs applied thereto.

Ifigure 2 is a top view of fig. l.

Figure 3 is a cross-section taken vertically through the rail, with the stop-chair applied to it.

Similar letters of reference indicate corresponding parts in the three igures. v

The object of this invention is to rigidly connect railroad-rails-to their cross-ties so that' any improper movement of the rails in the track will be prevented, and so that the cutting of the bases of the rails to effect this object is rendered unnecessary.

in the art to' understand Amy invention, I will describe its construction and operation.

In the accompanying drawingsl A A represent sections ot' railroad-rails of the wellknown T-form.

B are fish-bars, of two sections of rails at the joint, and held by means of bolts a and nuts b, in the usual well-known manner.

In fig. 3, G represents the cross-tie, upon which the rail A is secured.

I have thus described one very common form of railroad joint, for the purpose of showing that my iinproved chair is equally applicable to the rails 'at their joints as'at any other points.

which are clamped on opposite sides The nature of my invention consists in an angular plate, C, having a wide base-poltion,through which holes gV are made for receiving through them the spikes g', that are used to secure the chair down to a cross-tie, as shown in iig. 3.'

From the base-.portion d, a lip rises, a portion, c, of which is fitted upon the base of the rail', while the portion cis fitte-d to the side of -the iish-bar B, and perforated to receive through it the bolt a, by means of which, and the nut b,

rail.

Where the chairs are applied at the joints of the rails, as shown in' the drawings, the same bolts and nuts-which are used for securing the {ish-hars to the ,rails are used for securing the chairs thereto.

, At intermediate points between the rail-joints, the

elevated portions or lips of the chairs should be iitted to the webs or necks of the rails, and secured by bolts,

or in any other suitable manner, to the rails.

It will be seen, from the above description, that I have produced a stop-chair by means of which rails can be rigidly secured to their cross-ties without cutting away any part of the bases of the rails.

These chairs will be made either of wrought orcastmetal, of such form, size, and angles as are found best suited to the style of the rail or splice-bar for which they are intended.

Having described my invention What I claim as a new and manufacture, is-

A railroad stop-chair, consisting of parts c d, c, as herein set forth.
