EUG-ENE D. MANN, OF NEV YORK, N. Y.
SPECIFICATION forming part of Letters Patent No. 309,636, dated December 23, 1884.
To all whom it may concern:
Beit known that I, EUG-ENE D. MANN, of the city, county, and State of New York, have invented certain new and useful Improvements lin Sashes for Car-Vindows, of which the following is a full, clear, and exact description.
This invention consists in a sash or glazed frame for car-windows of peculiar construction, and in which double panes of glass separated from each other are used, the same forming or leaving a dead-air7 space between them, and having` combined with them and with the frame duplicate glazing-strips and soft or flexible beddings for the panes and glazing-strips, substantially as hereinafter described, and whereby the fullest advantages of a dead-air space, as affecting the temperature of the car, and in other respects, are obtained, and moisture and dust are efl'ectually excluded from between the glasses to impair l vision through them, andother advantages areV secured.
Reference is to be had to the accompanying drawings, forming a part of this specification, in. which similar letters of reference indicate corresponding parts in both the gures.
Figure l represents a face View of a glazed car-window sash complete constructed in accordance with my invention; and Fig. 2, a partial sect-ion, upon a larger scale, ol" the same.
A is the frame proper, made ol' wood or any other suitable material; B B, ,the glasses, and C C the glazing-strips which hold the glasses in the frame.
The frame A is constructed with longitudinal rabbets c c on both sides of its inner edge throughout its height and width, or, in other words, in each member of it. This leaves a center tongue, I), throughout the whole inner marginal portion ofthe frame to serve as a parting strip or stop between the two panes of glass B B, that, seated within the rabbets c c, leave a dead-air space, d, between them.
The glazing-strips C C are constructed with a shoulder, c, on their outer margins, to forni a liush or close and even nish with thesides of the frame A, and to leave an inner clamping space or cavity between said strips and the frame for one or more thicknesses, preferably double thicknesses, of plush, velvet, cloth, or other suitable soft and flexible material, arranged to form beddings D D for the edges and inner face portions of the glasses,which enter within the rabbets a c, to rest against. These soft and flexible beddings D D, for both thepanes and glazing-strips, serve to efl'ectually exclude both moisture and dust from entering within the dead-air space or chamber d to impair the efficiency of said chamber and vision through the panes, theinner faces ol' which are inaccessible for cleaning. Small nails or pins f are driven through the glazing-strips Gand soft beddings D, to securely fasten both to their places in the frame A.
I am aware that two panes of glass have been secured together, with an air-space between them,and then placed in a window-sash in the same manner that single panes'are; also, that double panes of glass have had sheets of muslin placed between them, the said double panes being placed in the sash in the usual manner; also, that the panes of glass have been double in a sash, in the sense that the edges overlap, and that said panes slide by each other, and I do not desire to claim any such construction as of my invention.
Having thus fully described my invention, I claim as new and desire to secure by Letters Patentl. Ina car-window sash, the l'ralne A, constructed with rabbets au on both sides of and all around or throughout its inner margin, leaving a centrally-arranged or intermediate tongue, b, between said rabbets, in combination with the panes B B, arranged to leave a dead-air space, d, lbetween them, the glazingstrips C G, and the beddings D D, of plush, cloth, or other soft and llexible material, whereby moisture and dust are eff'ectually excluded from the dead-air space between the frames, essentially as herein set forth.
2. The glazing-strips CG, constructed with a shoulder, c, on their outer margins, in combination with the double-rabbeted frame A of the sash, the separated panes B B, and lche bedding-S D D, of plush, cloth, or other soft secured in place Within the mbbeted frame, and exble material, arranged to pass Wit-hin substantially as specified.

strips and panes, and the whole may be readily y Within the rabbets of the frame, whereby the EDG-AR TATE, same beddings serve for both the glazng- ALFRED H. DAVIS.
