FRAME FOR MULTIPLE-FAME WINDOW SASHES Filed July 1a, 1946 Patented Apr. 4, 1950 OFFICE SASHES FRAME FOR MULTIPLE-PANE WINDOW Raphael Lemyre, Sore], Quebec, Canada In. Canada July '26, 1945 Application July 13, 1946, Serial No. 683,535

1' Y The present invention pertains toa novel frame for multiple-pane .window' sashes- The principal object of the .inventionis. to provide a frame that seals and insulatesthe spaces between the panes so that it is no longernecess'ary to provide a twopart or dualsash in order; to obtain an enclosed insulating space. I

Another object of theinvention is to provide a:sealed sash of thecharacter described which is especially suitable. for any kind of vehicle such as railroad cars, airplanes, motorcars, dirigibles, etc., and the like toinsure good visibility regardless of temperature variations on both sides of the window. Another object of the invention is to provide a frame that holds a plurality of panes of glass or: transparent plastic material with an airtight seal. Still another object of the invention is to provide a frame for multiple panes of the character described in which it isnecessary to clean only 6 Claims. (01. 20 56.5).

the outer surfaces of the respective panes due to the fact that the inner surfaces are protected from accumulation of dirt thereon.

Still another object ofthe invention is to provide a device of the character described which is simple and inexpensive in construction and easily assembled. I 1

In theaccomplishment of these objects, the invention comprises a single frame in which severalpanes are mounted. A tight seal for the space or spaces between the panes is formed by inserting the edges of the panes first in relatively solidresilient strips of naturalrubber, synthetic rubber or equivalent material. In order'to seal the spaces, .a means is provided for clampingthe resilient strips on their sides and thus against the individual panes. I

The last named means isincorporated in the moulding strips engaging the lateral surfaces of the resilient strips. Outward of the resilient strips, the binding strips are spaced apart and are formed with outwardly diverging inner surfaces. Between each pair of opposed moulding strips is inserted'a bind-ing strip with its longitudinal edges rounded and the moulding strips pivotally mounted thereon. A wedge inserted between the opposed moulding strips can be adjusted to rock'thelatter onthe intervening binding strips, thereby compressing the moulding strips in the inserted resilient strips and-sealing the-latter tightly against the panes. The wedge is'in theform of achannel-having outward or inward diverging sides and is attached by screws to the corresponding binding strip. The described clamping action on the resilient strips is obtained by tightening the screws.

because of the tight seal, Consequently, only the outer surfaces need be. washed If insuificient, in particular cases, a, thinmetal sheet could cover the rubber strip between the window panes.

The invention is fully disclosed by way of example in the following description and. in the.

accompanying drawingsin which:

Figure 1 is a cross section of a sash frame for multiple window. panes;

FigureZ is a detail elevation. thereof, partly. broken away;

Figure 3 is a perspective View of a corner;

Figure 41s a section similar to Figure 1,. showing also the stationary frame;

Figure 5 is a section on the line5+-5 of.Figure, 3, and

Figure 6 is a section of a modified construction.

Reference to these views will now. be made by use of like characters which areemployed to. designate corresponding parts throughout.

In Figures 1, 2 and 4 are shown two panes I spaced apart and having their: edges received in grooves or slots 2 formed in a surroundingstrip.

sections, assuming that the panes are quadrilateral; and the corners are miteredas shown in Figures 2 and 3.- The longitudinal outer edges. of thestrips tare rabbetedat 4, and the ad.-

J'acent-mouldingfstrips 5 at opposite sides of the strips 3 are formed with ribs 5:: received in. the grooves. 4. I

Abinding strip fi is laid. between the members 5 in engagement with the outer. transverse surface of each-strips. The edgess'lof the members 6; are rounded and received in correspondingly shaped grooves l. inithe stripsfi. Themember 6 unites the adjacent moulding strips5fand serves as a pivotal support for them for a purpose that will presently be described. I

outwardly of the members 6 the strips iare bevelled at- 8. on their inner surfaces so that the:

opposite surfaces diverge. outwardly. The 013-- posed surfaces are. engaged :by the inclined-flanges. 9 of aninserted ueshapediwedge member It). At-

as the strips rock on the ends of the members '6 as set forth above. The inner edges of the members 5 are compressed against the sides of the respective strips 3, thereby forming tight seals around the edges of the panes 1. Because of the tightness, there is obtained an air tight insulating space between the panes I, and this space may be filled with an insulating gas if desired.

The structure thus far described is enclosed in a frame, as shown in Figure 4, consisting of a pair of side members [2 united at a suitable lap joint I3 and secured by screws or nails. l4. The'ends of the strips 5 are mitered as shown in Figure 2 except at the extreme outer corners where they are cut and fitted on a joint line [5 parallel to one of the outer edges and fastened together by a dowel I6 as shown in Figures 2 and 3. Screws I! are .passed through the frame members 12 into the strips 5, and the inner surfaces of the members -|2 are flared slightly outwardly at 18 to permit the aforementioned rocking movement of the members 5.

In the modification shown in Figure 6 the resilient strips 3' are wider than shown in Figures 1 and 4 and are formed with four grooves 2' to receive the edges of .four panes I. The binding strip '6' and the spreader ID are likewise wider in order to engage the lateral strips *5.

Although specific embodiments of the invention have been illustrated and described, it will beunderstood that various alterations in the details of construction may be made without departing from the scope of the invention as indi cated by the appended claims.

What I claim as my invention is:

A sash frame comprising elongated resilient strips forming an enclosure for a window and having spaced grooves in their inner edges, spaced panes having their edges received in said grooves, moulding strips engaging the lateral surfaces of said resilient strips, binding strips inserted respectively between said opposed moulding strips and engaging the outer surfaces of said resilient strips, said moulding strips being pivotally attached to said binding strips, and means for rocking said moulding strips on said binding strips to tighten said moulding strips against said resilient strips.

2. A sash frame comprising elongated resilient strips forming an enclosure for a window and having spaced grooves in their inner edges, spaced panes having their edges received in said grooves, moulding strips engaging the lateral surfaces of said resilient strips, binding strips inserted respectively between opposed moulding strips and engaging the outer surfaces of said resilient strips, said moulding strips being-pivotally attached to said binding strips, wedging members inserted between said opposed moulding strips, and screws passed through said wedging members into the corresponding binding strips for rocking said moulding strips on said binding strips to tighten said moulding strips against said resilient strips.
