vJFIGJO @MW FRAME AND SASH CQNSTRUCTION Arthur E. Stiefvater, Happy Valley, Lafayette, Calif., assignor to Kawneer Company, Niles, Mich., a corporation of Delaware Application June 29, 1955, Serial No. 518,847

11 Claims. (Cl. 159-759' The present invention relates to a frame and sash construction and has for its primary object the provision of a new and improved split tube type of frame structure tor use on door jaambs, transom bars, mullions and the like.

Another object of the present invention is the provision of a new and improved split frame and sash construction including complementary frame members constructed to provide a dove tail type of groove when assembled and which are adapted to be secured in lassembled relation by a plurality of special headed screws cooperatively associated with the groove defining structure to hold glass panel retaining stops or glazing strips.

-In brief, the frame land sash construction of the present invention includes ya split tubular frame comprising complementary members having inset overlapping inner and outer portions at least at one and preferably at opposite sides land each of which has an inset groove which may be beveled, adjacent each of the two inset port-ions. The complementary members are held in assembled relation by a plurality of screws passing through the overlapping portions. The screws have enlarged head portions overlaying the outer inset portions and detining inset groove-like securing means for the reception of a glass retaining stop. A pane of glass is located in a plane passing between a set of beveled grooves and in .the plane of the screwheads. The pane of glass is held in place by glass retaining stops each having outwardly extending opposed feet portions, one of which is retained in the groovelike securing means provided by the screwheads and the other in an opposed inset groove in the frame member.

Other objects and advantages of the present invention will become apparent from the ensuing description of an illustrative embodiment thereof, in the course of which reference is had to the accompanying drawings, in which:

Fig. 1 is a fragmentary perspective view illustrating the combined frame and sash construction of .the present invention;

Fig. 2 is a fragmentary horizontal cross sectional view of an installation corresponding to that shown in Fig. l;

fFig. 3 is a transverse cross sectional view of a tubular frame member assembled in accordance with the present invention;

IFig. 4 is a perspective view of one of la number of spring clips which may be used resiliently to support a pane of glass between adjacent stops;

Fig. 5 is an elevational view of one of the special headed screws;

Figs. 6, 7 and 8 are a series of fragmentary vertical cross sectional views illustrating .the mode of installation;

Fig. 9 is a view similar to that of Fig. 3, but on a reduced scale, of a mod-.ined form of tubular frame construction; and

lFigl 10 is a fragmentary horizontal cross sectional view of a further modification of the invention.

Referring now to the drawings, and iirst to Figs. l, 2 and 3, the frame and sash construction of the present invention includes a tubular frame indicated as a whole nited States Patent r rice by the reference character 10 and illustrated best in Fig. 3. The tubular frame is of the split type and includes complementary frame members 12 and 14 having inset overlapping inner and outer portions 12-1 Iand l2-2 and 14-1 and 14-2, respectively. The complementary frame members are secured in .assembled relation by special headed screws indicated ,generally by the reference characters 16 passing through the overlapping portions of the complementary frame members. Each of the frame members includes an inset groove, which may be beveled, as shown, and preferably adjacent each of its inset portions. Thus, the frame member 12 is provided with an inset beveled groove 12-3 adjacent its inner inset portion 12-1 and a somewhat shallower inset beveled groove 12-4 adjacent the inset portion 12-2. In like manner, the frame member 14 -is provided with the inset beveled grooves 1443 and 1'4-4. When assembled, the resulting bevels are of like height.

The special headed screws .16 are provided with enlarged head portions 18 overlaying the outer inset portions of the complementary frame members. The screws are provided with threaded ends 20 threaded into at least the -undermost one of the overlapping portions. They also a-re provided with the enlarged (relative to the threaded portions) neck portions 22 which abut against the outer inset portions and thus space the enlarged heads somewhat from the frame members, thereby to provide what might be considered opposed grooves at the opposite sides of the screws and thus located in opposed relation to the grooves in the channel members. These grooves provided by the special headed screws are indicated by the reference characters 24 and 216, the former of which face the shallower Ibeveled grooves and the latter of which face the deeper grooves.

A pane of glass may be located between each set of beveled grooves 1243 and 12-44 and 1'4-3 and 1'4-'4 as has been illustrated in connection' with the pane of glass 3l) in Figs. l, 6, 7 .and 8. The glass may be supported at i-ts ybottom edge by supporting blocks, not shown, in conventional manner. The glass is actually supported in the plane of the screws and it is retained in place by glass holding stops, indicated by the reference characters 32 and 34, which lare `supported in the grooves provided by the special headed -screws and in the frame members. The stops 32 and 34 may be and are illustrated as being identical in construction. Each includes an upper horizontal part 36 .and the spaced apart dependent leg portions 38 and 40, the former of which terminates in what might be considered a foot portion 42 and the latter in a foot portion 44, which portions are respectively received and retained in the grooves provided in the frame members and by the headed screws. Generally, it is preferred that the glass actually be retained in place by the glazing springs which may be of the form illustrated in Fig. 4 and indicated by the reference character 46 which are retained 4between the glass panel and the legs '40 of the stops and underneath the projecting lips 48. Also, the stops may be somewhat resilient, or they may be solid, if desired.

A typical mode of installation is illustrated in Figs. 6, 7 and 8. Fig. 6 illustrates a portion of the tubular 'frame it) formed of the complementary members 12 and 14 which are held in assembled relation by` the screws 16. In the tirst step of the installation, one of the stops, such as the stop 3i?, is placed with its legs 38 and 40 to bring the foot portions 42 and 44 into locking relationship with the grcoves 12-4 and 24 in the frame and under the special headed screws, respectively. The glass pane or panel is set against the stop 32 which is now a substantially xed stop. Wedges 50` are then inserted between the foot 44 and the special headed screws securely to hold the stop 32 in place. The other stop 34 is then moved into place after the manner illustrated in Fig. 7, the distance between the feet being such as to enable the stops to be located in place by a sort of a rocking or back and forth movement to get the opposed feet into the associated grooves. Then the glazing springs 46 are placed in between the glass and the stops under the lips 48 at the upper and inner sides of the stops. Finally, with the springs in place the glass panel is centered and puttied thereby to provide a cornpleted frame and sash construction.

The present invention is adapted particularly for split tube frame constructions, but it may be used advantageously with integral tubular frames as illustrated in Fig. 9. In this figure there is illustrated an integral tubular frame 50 provided with the inset grooves 52 and 5ft-on one side of the groove and 56 and 58 on the other. Between the grooves are located the special headed screws 60 for the reception of the glass holding stops.

Fig. l0 of the drawings discloses an additional embodimentof the invention which obviates the need for wedges, such as the elements S0, by irmly securing one of the stop members to the frame construction. More particularly, the sash and frame construction 70 comprises a split frame including a pair of complementary frame members 72 and 74 which are similar to the frame members 12 and 14. These frame members are secured together in an overlapping position by a plurality of screws 76 having enlarged head portions 78. When the frame members 72 and 74 are secured in an overlapping position by the screws 76, a pair of inset beveled grooves 74-1 and 72-1 are provided for receiving and retaining a pair of pane stop members.

To secure a pane 80 of glass in an adjusted position relative to the construction 70, a pair of stops S2 and 84 are provided. The stop 82 is rigidly secured to the assembled frame members 72 and 74, and the stop 84 is detachably retained on these assembled members to secure the pane 8). More particularly, the stop 82, which is somewhat similar in configuration to the stops 32 and 34, includes an outwardly extending foot portion 82-1 which is adapted to be received within the groove 74-1. This stop is also provided with an oppositely directed foot portion 82-2 which is rigidly secured to the assembled frame members by clamping engagement with the enlarged head portions 7S of the screws 76.

The stop member 84, which is not rigidly secured to the assembled frame members but which is capable of being moved into a position in which it is retained thereon, includes a rst foot portion 84-1 which is received within the inset groove I2-1 formed in the frame member 72. The stop 84 is also provided with a second oppositely positioned foot portion 84-2 having an inclined upper surface 84-3 which is adapted to be received within the groovelike securing means dened by the enlarged heads 78 of the screws 76.

To install the pane 80 in the sash construction 70, the frame members 72 and 74 are moved into an overlapping position, and the iixed or secured stop member 82 is positioned on the assembled frame members with the foot portion 82-1 received within the inset groove 74-1. Thereafter, the screws 76 are threaded into the overlapped frame members and turned down so that the enlarged head portions 7S thereof engage and secure the foot portion 82-2 of the fixed stop member tothe assembled frame members 72 and 74 in addition to securing these two members together to form a unitary frame construction. The pane of glass 80 is then placed adjacent the rigid stop 82, and the stop member 84 is assembled on the frame construction by placing the foot portion 84-1 within the groove 72-1 and by inserting the foot portion 84-1 beneath the enlarged heads 78 of the screws 76, the inclined surface 84-3 facilitating the insertion thereof. Thereafter, glazing springs may be interposed between the pane 80 and the stops 82 and 84, anda suitable glazing compound 86 is inserted therebetween so as to provide a completed frame and sash construction.

While the present invention has been described in connected with certain illustrative embodiments thereof, it should be understood that these details are not intended to be limitative of the invention except insofar as set forth in the accompanying claims.
