IMPROVEMENT IN RAILWAY-CAR WINDOWS.

Specification forming part of Letters Patent No. 178,302, dated June 6, 1876; application filed March 27, 1876.

' ings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in-

Figure 1, face view; Fig. 2, transverse section.

Y This invention relates to an improvement in sashes for railroad-coaches and like purposes, the object being to prevent the disagreeable rattling which attends the usual construction, and the entrance of dust or air around the sash.

The invention consists in constructing the stile, one or both, in two parallel divisions, combined with an elastic material between, as more fully hereinafter described.

A is one part, and B the second part,'0f one stile. The facing edge of these two parts is made concave in transverse section, as seen in Fig. 2. Between the two parts a tube or solid cylinder, at, of elastic material, is arranged, the

relative position, rods or supports d extend The sash is arranged in place in the usual manner, the Whole width of the sash, when the spring is free, being a little more than the width of frame from jamb to jamb, and so that in placing the sash the spring or elastic material must to some extent be compressed, and when in place the spring reacts, expanding the sash, or hearing its edges hard against the respective jambs, so as to prevent rattling or jarring by the movement of the carriage or the entrance of dust or air around the sash, but yet so as to allow the sash to be easily raised or lowered.

While the cylindrical form of spring is preferable, this invention is not confined to that form, it only being essential that the stile be made in two parts, one movable to or from the other by means of an elastic material between the two.

I do not wish to be understood as broadly claiming the arrangement of a spring in the stile to bear against the jam'b, as such I am aware is not new.

I claim The herein-described improvement in sashes for land and other conveyances, consisting in the stile divided vertically into two parts, combined with an elastic material between the two, and with suitable guides to retain the said two parts in substantially the same relative position, substantially as specified;
