Description

Patented May 17, 1932 UNITED STATES PATENT OFFICE HARRY E. CAMPBELL, OF BALTIMORE, MARYLAND, ASSIGNOR TO CAMPBELL "j WINDOW CORPORATION, OF BALTIMORE, MARYLAND, A CORPORATION OF MARY- LAND WINDOW FRAME AND SASH Application filed December 18, 1930. Serial No. 503,167.

This invention relates to a window construction in which the sashesare so constructed that the glass can be held throughout by metallic members which are readily inserted in place, and certain phases of the invention are particularly applicable to casement windows in which a supplemental stiffening effect is provided.

The invention can best be understood by reference to the accompanying drawings, in-

members

10 and 12 which are all mitred at the corners and welded together. These members all have substantially similar contour about the frame, subject only to such changes at the t'opor bottom as circumstances may desire for installing the frame. These members are here shown as bent out of sheet metal into a form having a flat portion 14 toward the outside, a portion 16 running between the inside and the outside and an innor portion 18. The detailed shape may be modified in many particulars, the important feature being that the usual L-shaped recess is supplied as is here formed by the

portion

16 and 18. Against the portion 16 I preferably weld members 20 forming pockets to receive weather stripping felt 22. thus making it unnecessary'to have a tight weatherseal at the inner line of contact.

i The sash, like the frame, consists of four primary members, all of like contour, which are welded together, at the corners. As these members are similar except for their length I have designated all of them by the numeral 24. Each member 24 comprises a fiat outer portion or plate 26, the end of which is adapted to contact with the outer fiat portion 14 of members10 and 12, and has a portion 28 bent inwardly. This member 24: is

bent as shown in Fig. 3 to form anoifs et glass rabbet, designated by the numeral 30, and finally an inner portion 82 which overlaps the inner portion 18 of the frame but does not contact therewith. By forming these sash members of relatively heavy sheet metal (say 12 gauge) bent in'this manner to form an outer flat plate (which contacts with the frame and extends. across to the line of the opening) together with an inwardly extending portion, a glass rabbet, and the inner portion 32, I not only get the necessary contour for holding. the glass but also. because of the number of bends and the number of portions which are positioned at substantially right angles to each other, I am;

able to obtain a one-piece sheet metal sash frame member substantially as stiff as the usual members formed of hot rolled sections.

If further stiffening is desired along the hin e side or opposite the hinges; I can easily weld in place a supplementary stiffening piece. as shown at 33 in Fig. 3 so that particular stiffening is given at the point of maximum strain without increasing the weight of the entire sash frame. Welded to member 24, preferably in the glassrabbet 30, is a member 34: made of relatively thin metal. This member follows the contour 'of'the glass rabbet and extends alongthe inner face of portion 32 and then is bent back on itself twice as clearly shown in Fig. 5 to form the glass stop. channel 36 with a restricted open- 'ing.

It is to be understood that there are four members 34 which extend entirely around the sash. Glass stops 38 are provided to slip into the glass stop channels36. The top and bottom glass stops preferably extend entirely across the sash, whereas the two side ones extend vertically between the top and bottom glass stops as shown in Fig. 1. If desired,

the bottom glass stop 38 may be built permanentlv in place to form. a glass channel. Each of the glass stops- 38 has. at'spaced points. portions struck up to form projections as shown at 40. These glass stops canbe forced in under the reverse bend of member 36 which will snap into place holding the glass stops in proper position. To remove a glass stop, ascrew driver, or similar instrument, can be inserted adjacent one of the stops 40, lifting the reverse bend of member 34 so that the glass stop can be removed. With the construction shown, projections 40 are not necessary at the top, but I prefer to use them.

The muntin bars 42 are shown as of solid H-se-ction and are cut out at the intersections so as to fit together in the manner shown in Fig. 4. The intersecting points are'preferably welded together so that the muntin bars become practically a unitary structure. The glass rabbet 30 is made of sufficient size so that the projecting ends of the muntin bars will extend down into this rabbet between members 34 and glass stops 38 as shown in Fig.3.

To glaze the window, the two side glass stops 38 are removed and then the top glass stop, permitting the muntin bars 42 to be removed as a unit. The sockets in these muntin bars are then lined with putty and the panes of glass then slipped into place. Additional putty is then put in the glass rabbet and the muntin bars and glass are inserted as a whole, after which the glass stops 38 are put back into place. In order partly to cover the putty, I may, if desired, bend the edge of each member 34 inwardly as shown in Fig. 3 at 44, but this edge must be straightened up as shown at 46 at each point where an end of the muntin bar enters the glass rabbet. Inlike manner, I may form on the edge of the glass stops 38 a ridge 48 which is cut away as indicated at 50 at each point where one of the muntin bars enters the glass rabbet.

It. will be noted that the inner portion of member 34 contacts with portion 18 of the frame members when the window is closed, so that even though I rely on the bending of members 34 to insert the. glass stops, these members will be supported by contact against portions 18 of the frame. Thus when the window is drawn tightly shut any strain exerted by air pressure tending to bend members 34 will be transmitted directly against the fixed frame members. It is to be further understood that this construction of sash can be used without muntins, either with a single pane of glass or where the glasses are leaded together.

The term outside is used in this case as designating that side of the window from which the sash moves in closing, which usually will be the outdoors side, but may be the indoors side if the window swings into the room.

What I claim is 1. In combination, a casement window frame having the usual L-shaped recess and a sash frame having the usual plate adapted to contact with such frame on .the outer face thereof, a glass rabbet formed on the sash adapted to receive glass from the inside, yieldable members on the inside of the sash and united therewith forming glass stop channels with restricted openings, and adapted substantially to contact with the inner leg of the frame when the window is closed, and glass stops having projections adapted to be snapped into said channels so that when the window is closed said glass stops will be held in place by said yieldable members and said yieldable members will be reinforced by said frame.

:2. A structure as specified in claim 1 which further includes a set of united intersecting muntin bars of H-section having their ends entering said glass rabbet and held in place by said glass stops and removable'as a whole when said glass stops are removed.

3. A structure as specified in claim 1, which further includes compressible material carried by the window-frame and extending around the periphery thereof adapted to contact with the said plate on the sash frame before such plate contacts with the fixed portions of said window-frame whereby a seal may be maintained towards the exterior of the window while said yieldable members are held compressed against said windowframe.

4. In combination, a casement window frame having the usual L-shaped recess and a sash frame having the usual plate adapted to contact with such frame on the outer face thereof, said sash frame having portions which extend inwardly from the aforesaid plate and are formed with a glass rabbet continuous around the sides and top and opening toward the inside, the inside edge of such portion being substantially outside of the inner portion of the frame when the window is closed, yieldable members united with the sash frame and extending inwardly therefrom and having aportion spaced away from such frame to form glass stop channels with restricted openings, substantially flat glass stops adapted to be forced into said channels and means carried by the glass stops for looking them in the channel.

A window'sash frame having a glass rabbet extending. continuously around the sides and top, a set of united intersecting muntin bars of H-section having ends adapted to enter such glass rabbet and removable stops adapted to hold said ends in said glass rabbet. said muntinbars being removable as a whole when said glass stops are removed.

6. In combination, a casement window frame having the usual L-shaped recess and a sash frame having the usual plate adapted to contact with such frame on the outer face thereof. said sash frame consisting principally of four pieces of bent sheet metal united at their ends to form corners, each such piece comprising the said outside plate, an

inwardly extending portion, portions respectively at approximately right angles to and parallel with said inwardly extending por tion to form a glass rabbet opening towards the inside, and an inside portion parallel with said plate, whereby the sash frame is shaped to receive the glass and stiffened by the large number of bends formed in its members.

7. A window sash frame having parts forming a glass channel on one of its four sides, rails on the other three sides shaped to form lass rabbets ada ted to receive -lass b Y b from the inside, members on the inside of such rails and united therewith forming glass stop channels having openings to receive glass stops, means for restricting such channel openings, and solid glass stops of a thickness substantially equal to the width of such restricted openings adapted to enter such channels, at least two of such glass stops hav ing projections adjacent their entering edges adapted to wedge past such restricting means and to snap into place behind the same to hold the glass stops in place in the sash frame.

8. A window sash frame having parts forming a glass channel along the bottom, rails on the two adjacent sides shaped to form glass rabbets adapted to receive glass from the inside, members on the inside of such rails and united therewith forming glass stop channels havingv openings to receive glass stops, means for restricting such channel openings, solid glass stops of a thickness substantially equal to the width of such restricted openings adapted to enter such channels having projections adjacent their entering edges adapted to wedge past such restricting means and to snap in placebehind the same to hold the glass stops in place in the sash frame, and means for holding the top edge of the glass in place.

9. A window sash frame having parts forming a glass channel along the bottom, rails on the two adjacent sides shaped to form glass rabbets adapted to receive glass from the inside, resilient members on the inside of such rails and united therewith forming glass stop channels having openings to receive glass stops, means for restricting such channel openings, glass stops adapted to enter such channels having substantially non-compressible projections adjacent their entering edges adapted to wedge against restricting means to widen the channel opening and adapted to snap into place behind the restricting means to hold the glass stops in place in the sash frame, and means for holding the top edge of the glass in place. 7
