WINDOW=SASH.

SPECIPICATIQN forming part of Letters Patent No. 390,179, dated September 25, 1888. Application filed March 10, 1888. Serial No. 266,895. (No model.)

To (tZZ whom, it? may concern;

Beit known that I, HENRY MAEURER, a citizen of the United States, and a resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Window -Sashes, of which the following is a specification.

My invention relates to an improvement in window-sash; and it consists in so construct ing the sash that it may be turned over in its frame, thus presenting the outer side of the glass inwardly, whereby after the inside of the glass has been cleaned the outside may be turned inwardly, thus presenting it toward the room, and when in this position it may be easily cleaned. Thus the annoyance, inconvenience, and danger attending the cleaning of the outside of the glass are avoided.

In the drawings the same rcfereuceletters indicate the same parts in all the figures.

Figure 1 illustrates a plan ofthe invention. Fig. 2 illustrates a sectional view on the line arm of Fig. 1, showing the clamp which unites the side bars of the sash to the strip which runs in the rabbet of the window-casing. Fig. 3 illustrates a top view of the parts shown in section in Fig.2. Fig. 4 illustrates asectional view through the center of one of the pivots on which the sash turns.

In the drawings I show only the lower one of a pair of sashes. The fittings of the other, being identically the same so far as my invention is concerned, need not be shown.

A is the sash. B is the glass.

0 G are strips of wood or othersnitable material, which slide up and down in the sash rabbets formed in the window'casing, as usual. These strips 0 O are of the same length as the sash, and are of somewhat greater thickness than the strips attached to the casing which form the said rabbets, so that the sash may be turned Without striking them.

D D are two pivots or pins on which the sash turns. They may be made as shown in Fig. 4, having one end, E, driven into the side rails of the sash A, and the other-end, F, which is preferably somewhat reduced in diameter, passes through a bushing, G, placed in the strips 0 O. A washer, H, is placed on the end of the pivot which overlaps the end of the bushing and holds the strips Osnugly against the side rails of the sash. The washer is held in place by a screw, H, tapped into the end of the pivot, there being also, preferably, a small pin, I, passing through the washer and entering the pivot to prevent turning of the washer. I prefer that the bushing should have a flange, J, which is countersunk into the side of the strips 0.

K K K K are four clamps, two on the inside and two on the outside of each sash. Those near the upper end of the sash are on the same side, and those near the bottom thereof are on the other side. They are preferably made as shown in Figs. 2 and 3.

L is a right angle piece of metal screwed to the side of the sash-bars. It may be let into the same, if desired, to make a better finish. The right-angle end L is offset from the edge of the sash-bar sufficiently to allow a piece of metal, M, set edgewise, to pass between it and the edge of the sash-bar. This piece of metal M is fastened by screws or otherwise to the strips Q, as seen in Fig. 8. Near the end of the riglitangle part of the piece L, I thicken the metal somewhat, as shown at 0, thus producing a slight crowding action when the parts are brought together, which very slightly springs the piece L. Thus the strip 0 is drawn closely up against the edge of the side sash-bars and the joint is made tight.

The operation is as follows: The glass having been cleaned on the inside, the sashloek is unfastened and the upper rail of the sash is taken hold of, preferably with both hands and near the sides of the sash, and is pulled over inwardly toward the room. This disengages the clamps K K K K from the plates M M M M, and the sash then turns over, swinging on the pivots D D, thus presenting the outer side of the glass inwardly toward the room. That side of the glass being cleaned, the sash is again turned on its pivots and pressed back again into its place until the 9 clamps engage with the plates M, &c., as be fore. It will thus be seen that all inconvenience and danger of reaching out of the window or standing or sitting on the window-ledge to clean the outside of the glass is avoided.

Ido not limit myself to the details of construetion shown,sinee alterations may be made therein and still my invention be employed.

Having described my invention, I claim- 1. The combination, in awindow-sash, of a glass-containing frame, A, and side strips, C, the frame being pivoted to the side strips,and automatically-acting clamping and releasing devices at the upper and lower parts of the 10 frame and on opposite sides thereof, whereby the frame and the strips are attached and detached to and from each other by pressure on the frame alone, substantially as set forth.
