JOHN O1 HOOD, OF IVILKINSBURG, PENNSYLVANIA.

SLIDING WINDOW.

SPECIFICATION forming part of Letters Patent No. 583,375, dated May 25, 1897.

Application led November 6, 1896. Serial No. 611,239. (No modell)v To all whom t may concern: l

Be it known that I, JOHN O. I'IOOD, a citizen of the United States, residing' at Vilkinsburg, in the coun tyof Allegheny and State ofPenn- Sylvania, have invented new and useful Improvements in lVindows; and I do hereby declare the following to be a full, clear, and exact description of the same.

The invention relates to that class or description of windows which are provided with vertically-movable sashes; and its object is to provide an improved construction of the same by which the sash is securely held against rattling, while at the same time it will not stick or bind, so that it can be readily raised and lowered.

The invention consists in the novel construction and combination of parts hereinafter fully described and claimed.

In the accompanying' drawings, Figure lis a longitudinal sectional View of a windowsash and a portion of a window-frame with my improvements applied thereto. Fig. 2 is a horizontal section on the line X Y, Fig. 1. Fig. 3 is an elevation showing a portion of the side of a vehicle provided with my improvements and also showing means forinflating the pneumatic tubes.

In the said drawings the reference-letter A designates the glass of a sliding-window sash, and B the frame thereof. The vertical side rails of this frame are formed with concave grooves, in which are seated concavo-convex plates E, securely xed to said rails.

'lhe letter F designates the side rails of a window-frame, formed in the inner side with semicylindrical vertical grooves, in which is seated a flexible pneumatic tube D, provided at the lower end with a nipple G, extending through an opening in the lower rail of the window-frame. These nipples are to be provided with valves, (notshowm) and the tubes can be inflated by an ordinary air-pump.

The letter C designates'a vertical concavoconvex strip, crescent-shaped in cross-section, interposed between each pneumatic tube and the plate E of the window-sash. The lower ends of these strips lit in recesses II in the lower rail of the window-frame, whereby their movement is limited, while their upper ends are free.

A window provided with my improvements will possess superior advantages, as the sash will not rattle, and will not stick or bind, yet a perfectly tight joint will be formed, so as to exclude dust and water.

In Fig. 3 I have shown my improvements applied to the windows of arailway-car which is provided with air-brakes. (Not shown.) The nipples G in this instance are connected by means of branch pipes O with a horizontal pipe M, connected in turn by a pipe N with the train-pipe. (Not shown.) By this means the tubes can be iniiated by the air-brake compressors, suitable valves of course being provided at proper points.

While I have shown the plates E and strips O as being concavo-convex, they maybe in ade rectangular or flat, if desired.

Having thus fully described my invention, what I claim is.-

I. The combination with a window-frame the side rails of which are formedwith semicylindrical grooves in their inner sides and the lower rail formed with a recess near each end and the pneumatic tubes located in said grooves having nipples at the lower ends passing through openings in said lower rail, of the window-sash, the vertical plates secured to the side rails thereof, and the strips interposed between said tubes and plates with their lower ends resting in the recesses in the lower rail of the window-frame, substantially as described.

2. The combination with a window-frame having seinicylindrical grooves in` the inner sides ofthe side rails and the lower rail formed with a recess n'ear each end, and the pneumatic tubes located in said grooves provided with nipples passing through openings in said lower rails, ot' the window-sash having a concave groove in the side rails, the concavo-conveX plates seated in said grooves, the vertical strips crescent-shaped in cross-section interposed between said tubes and plates with their lower ends resting in the recesses in the lower rail of the window-frame, substantially as described.

3.
