WINDOW SASH F iled June 14', 1944 m a l 2//////E f 1 20 2* I I E ZNVENTOR.
Patented Sept. 24, 1946 UNITED STATES PATENT OFFICE] James Gerow Wilkin, New Hurley, N. Y. Application June 14, 1944, Serial No. 540,352
It is a matter of common knowledge that when it is desired to clean a window pane, considerable difliculty is experienced in wiping close to the mullions. The foregoing difficulty having been appreciated, the present invention aims to provide mullion structures which are removable reading from the sash, the sash enclosing a single pane which, after the removal of the mullions, may be cleaned readily.
It happens, moveover, that occasionally it is desired to change the mullion pattern of a Window, and thepresent invention aims to supply a novel means whereby a mullion of one pattern may be substituted for a mullion of another pattern.
A further object of the invention is to supply a flexible mullion which, on account of its flexibility, may be mounted readily on a window sash and with equal facility be removed therefrom.
Within the scope of what is claimed, the structure described and shown may be changed, without departing from thespirit of the invention.
In the accompanying rawin Fig. 1 shows, in front elevation, a window sash equipped with the device forming the subject matter of this application;
Fig. 2 is a vertical transverse section on the line,
22 of Fig. 1, parts being broken away;
Fig. 3 is an enlarged section taken through one of the seats;
Fig. '4 is a section on the line 4-4 of Fig. 3;
Fig. 5 is an elevation showing a portion of the mullion structure, including one construction by which the mullion structure is made flexible;
Fig. 6 is a sectional view showing the mullion structure partially folded, to permit the assembly thereof with the frame;
Fig. 7 is a sectional View looking toward one of the seats which receive the mullion-ends;
Fig. 8 is a section on the line 88 of Fig. '7;
Fig. 9 is an elevation similar to Fig. 5, but disclosing a modified structure wherein flexibility in the mullion structure if obtained by means other than that disclosed in Fig. 5.
Fig. 10 is a sectional view taken through a portion of the sash and a portion of the pane.
In carrying out the invention there is provided,- in the building material art, a sash S, comprising a frame I. In its inner edge, the frame I is supplied with a continuousrecess 2, wherein the marginal portion of .a pane 3, of glass or the like, is held by putty 2a, or equivalent means.
At spaced distances, the inner portion of the frame I is provided with outwardly tapering seats 4. Preferably a single pane 3' is employed, the

pane occupying the entire area bounded by the frame I, r
In each seat 4 is disposed a grip G, made of The grip G comprises a U-shaped shank 5, the constituent parts of which are in contact. The shank- 5 bears at its outer end against the frame I, as shown in Fig. 3, at the base of the seat 4. portions of the shank 5 are spaced as shown at 6, the side portions being resilient and terminating in laterally extended, resilient loops I.
Mullion structures are disposed on opposite sides of the pane 3 and extend across the pane.
'Ihe mullion structures may be made in various ways, without departing from the spirit of the invention. Preferably, but not of necessity, each mullion structure includes a horizontal rail 8, including a long part 9 and a short part II], disposed in alinement. The inner ends of the parts 9 and ll) of the horizontal rail 8 abut along a line indicated by the reference character I! in Fig. 5.
Each mullion structure includes a vertical rail I2, comprising parts I4 disposed on opposite sides of the horizontal rail 8. The abutment line Ii between the parts 9 and I0 of the rail 8 coincides wtih one longitudinal edge of the vertical rail I2. A resilient strip I5, made of metal or other suitable material, connects the parts I4 of the vertical rail I2, and extends across the member 9 of the horizontal rail 8, the strip I5 being secured at I6 to the rail parts I4. A similar strip I1 extends across the strip I5, at right angles thereto, and is secured at I8 to the members 9 and It of the horizontal rail 8.
From the foregoing, it will be noted that the rails 8 and I2 are flexible, the flexibility being secured by means of the strips I5 and IT. The strips I5 and I1 are let into the rails, so that the rails present a smooth inner edge to the glass pane 3.
Another vertical rail I 5 may be provided, as shown in Fig. 1, this rail comprising parts disposed on opposite sides of the member 9 of the horizontal rail 8, the constituent portions of the vertical rail I9 being connected by a hinge strip like the hinge strip I5 of Fig. 5, the hinge strip I1 being omitted. In general, the constituent parts the horizontal and vertical rails may be made in various ways, it being necessary, merely, that there bea sufl'icient number of hinges so that the mullion structures are flexible.
The rails of the mullion structures terminate in fingers 20, shaped to be received in the seats 4. The fingers 20 are somewhat narrower than The side the mullion rails proper and, therefore, there are formed at the ends of the mullion rails proper, on opposite sides of the fingers, transverse shoulders 2| and 22, the shoulder 22 being disposed adjacent to the pane 3, and the shoulder 2| being disposed atthe outer surface of the mullion rail. About the fingers 20 are disposed compressible gaskets 23, and the shoulders 2| and 22 press the gaskets against the inner edge of the frame I and make watertight joints. This construction preferably is carried out in connection with the outer mullion structure only.
In the inner surfaces of the fingers 29, recesses 24 are formed. The recesses 24 are shaped to receive the resilient loops 1 of the grips G. The recesses 24 and the loops 1 constitute releasably interengaged elements on the fingers 2i] and on the grips G, respectively.
To position the mullions, the grip G at one end of the mullion to be positioned, is placed within the seat 4 and the fingers 20 at one end of the mullion, are positioned Within the recess. The fingers are forced against the loops 1 of the grips, the loops 1 moving into the recesses 25 of the fingers. The opposite end of the mullion is now positioned in a similar manner, with the, result that the mullion is secured against flexing and consequently, held in place, under normal conditions.
As shown in Fig. 6, each mullion structure may be molded at the hinges l5 and ll, so that the fingers 20 can be withdrawn from the seats 4. This enables both mullion structures to be removed, facilitating a cleaning of the pane 3,
there being no obstructing mullions in the path of the cloth or other device used to clean the pane.
It is not necessary that the mullions be provided with hinge strips Iii-ll. Thus in Fig. 9, the mullions 3B are of one-piece construction, and are made of material which has inherent resiliency.
If the operator desires to change the mullion pattern, the mullion structures shown in Fig. 1 may be removed and be replaced by mullion structures of a different design, the seats 4 providing for such an operation. Referring to Figs. 7 and 8, the seats 4 which are not occupied by the fingers 2a of the mullion rails may be closed by plugs 26, havin side recesses 2'! for the reception of the loops 1 of the grips G, the plugs terminating in laterally extended heads 28, compressible gaskets 29 being interposed between the heads 28 and the frame I to prevent leakage into the seats 4.
The device, in either of its forms, is simple in construction, but will be found thoroughly advantageous to carry out the operations described in the opening portion of this specification, and elsewhere therein.
What is claimed is:
l. A Window sash comprising a frame, a pane carried by the frame, said frame having cut-out portions formed in the inner edges thereof, providing seats, a mullion including rails, fingers formed at the ends of the rails and adapted to be fitted within the seats, and members mounted within the seats adapted to grip the fingers positioned within the seats, holding the fingers and mullion against displacement.
