WINDOW-SASH CONSTRUCTION.

Application filed January This invention relates to window sashes particularly metal sashes such as are used in railway cars, motor vehicles, busses and for wind shields and has for its object a sash construction by which the sash memhere are secured directly together at the corners in a particularly simple, economical and eflicient manner.

The invention consists in the novel features and in the combinations and constructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanying drawing in which like characters designate corresponding parts in all the views.

Figure 1.--is a fragmentary elevation, partly in section of a corner portion of a sash embodying my invention, the other corners being substantially the same.

Figures 2 and 3 are edge views looking respectively to the right and upwardly in Figure 1.

Figures 4 and 5 are respectively a fragmentary edge and end views of one of the sash members and Figures 6 and 7 are similar views of the other sash member. I

This window sash construction comprises sash members which meet at an angle, the members abutting against each other at the corners and having interfitting parts and a fastening member extending edgewise through one of said members and lengthwise of the other or second member, and also extending through the part of the second member which interfits into the first member.

The sash members are formed with channels in their inner edges for receiving the glass pane and one of such members is formed with a projection at its end which fits into the channel7 f the other member and abuts against the bottom thereof; and the fastening member as a screw extends edgewise' through the latter member and lengthwise of the former.

As here illustrated, each channel member is H shaped in cross section or in end elevation and one member is formed with a. projection coextensive with the cross bar of the H formation which projection extends into the inner channel of the other member, and the fastening screw extends edgewise through the latter member or the cross bar thereof and lengthwise into such projection of the cross bar of the former member.

1 and 2 designate respectively the sash 8, 1925. Serial No. 1,322.

members which meet at an angle ateach corner of-the sash, one of these members, here shown as the horizontal member or rail 2being formed with a projection 3 at each end substantially coextensive with the cross bar 4 of the H formation, this projection.

When the sash members are brought together, the end edges of the side flanges of the member 2 abut as at 10 against the inner lengthwise edges of the side flanges ofthe member 1.

11 is the fastening screw which extends edgewise through the member 1 or the cross bar 7 thereof and endwise of the cross bar of the member 2, the cross bar 7 of the member 1 being provided with an unthreaded passage 12 for the screw 11 and the membei 2 or the cross bar thereof being formed with a threaded passage 13 for receiving the screw, but one screw is preferably used at each corner. The sash members thus meet each other squarely at their ends and the screw is arranged to draw the sash members at a right angle to each other in a firm abutting relation, and these screws extend through the interfitting parts of the sash edgewise through one sash member and lengthwise of the other sash member. In other Words, the sash members interfit and abut at the corners, the flanges of one sash member lap an interfitting part on the other sash member and the screw is so arranged that it draws the sash members thus lapped at a right angle to each other into firm abutting engagement.

The channels 9 particularly the channels in the upright members of the sash are for the purpose of coacting with sash guides on the window frame or with a weather strip. The outer channel of the horizontal member is to receive a buffer strip. The inner channel is for the purpose of receiving a glass frame 14 and a marginal packing piece as a rubber channel 15.

In practical construction, the horizontal sash members or rails 2 extend under or over the ends of the rails so that the rails extend the full width of the sash, and the stiles are located between the rails, instead of as shown the stiles extending the full height of the sash and the rails interposed between the stilesa The sash members are formed from standard or stock H shaped bars which are formed by an extruding process. This sash construction is particularly advantageous in that they are made up of stock bars or channels which are alike inform and caused to interfit and join at the corners without the use of corner irons and transversely extending screws. Furthermore, owing to the H formation and the central location of the projection either channel can be used to receive the glass and no care need be exercised in assembling the stiles and rails in a particular relation. v

The sash construction with particular reference to the manner it coacts with a window guide or a window frame forms no part of this invention but forms the subject matter of my pending application Sr. No. 55,- 765, filed September 11, 1925.

What I claim is:

A window sash consisting of metal members substantially H-shaped in cross section whereby the sash members are formed with grooves in their inner edges for receiving the glass pane and channels in their outer edges, the connecting piece of the H formation being in the form of a rectangle approaching a square in cross section where by the end faces of one of said connecting pieces forms a substantial bearing surface for abutting against the side face of the other connecting piece, the connecting piece of the H formation of one sash member which meetsanother to form a corner terminating short of the end of such member an amount equal to the depth of said channel and the other of said sash membershaving its connecting piece projecting beyond the end of the same an amount equal to the depth of the groove and abutting against the end portion of the connecting piece of the former member, and a screw extending transversely through the end portion of the connecting piece of the former member and lengthwise into the connecting piece of the latter member whereby the end edges of the side pieces of the H formation of the latter member abut against the ,side edges of the side pieces of the former member when the end of one connecting piece bears against the side of the other connecting piece.

In testimony whereof, I have hereunto signed my name, at Syracuse, in the county of Onondaga, and State of New York, this 9th day of December, 1924.

ROY T. AXE.
