WINDOW CONSTRUCTION.

Application filed December 4, 1923. Serial No. 678,540.

T 0 all whom it may concern:

Be it known that I, ARCH LAWRENCE MAsoN, a citizen of the United States, and a resident of Meadville, in the" county of Crawford and State of Pennsylvania, have invented a new and Improved Window Construction, of which the following is a full, clear, and exact description.

This invention relates to window construct-ions, and has for one of its objects to provide an improved window in which sec tions of the sashes may be removed to permit of cleaning the window from the interior of a room and without the necessity of sitting Or standing on the sill of the window as is customary.

Another object is the provision of a window of comparatively simple and inexpensive construction, which may be manufactured and installed at a minimum cost.

The above and other objects will appear more clearly from th following detail description, when taken in connection with the accompanying drawing, which illustrates a. preferred embodiment of the inventive idea.

In the drawing Figure 1 is a front elevation of the window with one of the sashes broken away;

Figure 2 is a section on the line 22 of Figure 1; and

Figure 3 is a section on the line 3-3 of Figure 1.

Referring more particularly to the accompanying drawing, the window frame is shown as consisting of a sill 4 and the vertical stiles 5 which are grooved in the usual manner to -receive the upper and lower sashes, generally indicated by the numerals 6 and 7, respectively.

Each of the sashes consists generally of outer and inner sections 8 and 9 arranged one within the other, the inner sect-ion carrying the usual pane of glass. The outer sections of the two sashes include the usual meeting rails 10 and the side rails 11 which slide in the grooves of the stiles 5 and have attached thereto the usual sash cords (not shown), in a manner well known in the art, so that the sashes may be raised and lowered whenever desired. The side, top and bottom rails of the sashes may be mortised together in the usual manner and in order that sash are provided on the exterior vertical edges thereof with the tongues or flanges l3 engageable in correspondingly shaped grooves let formed in the vertical rails 15 of the inner section 9 of the sash. The top and bottom rails of the outer section of each sash are beveled upon their inner edges, as clearly indicated at 16 in Figure 2, to en gage correspondingly shaped beveled edges 17 of the top and bottom rails of the inner section of thesash. This construction per: mits of th inner section being fitted within the outer section and when the vertical rails of the inner section are engaged with the flanges 13 further outward movement of the inner section with respect to the outer section will be preventec. In order to secure the inner sections of the sashes in their closing positions the same may be provided with spring latches, conventionally illustrated at 18, the latching members of which extend into suitable openings formed in the vertical rails of the outer sections The inner section of each sash may thus be withdrawn inwardly into a room from engagement with the outer section by adjusting the latches 18 to their inoperative positions.

What is claimed is:

In a window construction, a sash including inner and outer sections arranged one within the other, the vertical rails of the outer section having flanges and corresponding rails of the inner section having grooves for receiving said flanges to limit the outward movement of the inner section, and the top and bottom rails of one section having beveled unobstructed edges engageable with correspondingly formed edges of the top and bottom rails of the other section, and latching means carried by the inner section and engageable with the outer section to retain said sections in closing position.

ARCH LAWRENCE MASON.
