Patented Jan. 2, 1940 PATENT. OFFICE WINDOW CONSTRUCTION Edward F. Chai'fee, Syracuse, N. Y., assignor to The 0. M. Edwards Company, Inc., Syracuse, N. Y., a corporation of. New York 1 Application March 11, 1938, Serial No. 195,366

Claims. (01. 189-64) This invention relates to window constructions, and primarily to double window constructions, and has for its object a window construction embodying two sash frames, each of which supports 5 a glass panel, which sashframes are mountable as a unit in the window opening and are shaped to provide between them an internal channel for receiving a moisture-absorbing material to absorb the moisture from the air in the space between the glass panels.

.It further has for its object a double sash construction wherein either glass can be removed and replaced, independently of the other glass in combination with readily removable retaining or glazing strips associated with the sash frames and removable and replaceable independently of each other.

It further has for its object a simple double sash construction including peripheral flanges 2 on the sash frames, which flanges are opposed to each other and secured together so that the sash frame may be mounted and demounted in a window opening as a unit, and further, the unit secured in the window opening by means of said flanges.

A secondary object of the invention is a nonadhesive strip between a backing or cushioning strip for the margin of the glass pane and the .back wall of the channel in which the margin of the glass pane is located, so that by reason of groove IE or l1 located in a plane tothe' outthe non-adhesive strip, the glass does not stick to the backing strip, and hence the backing strip is not .mutiliated, nicked or torn when the glass pane or splinters thereof are removed.

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 of a window structure embodying this invention.

Figure 2 is a sectional view on line 2-2, Figure l, the adjacent parts of the frame around the window opening being shown.

Figure 3 is a cross-sectional view throughthe lower rail of the sash. 1 I

Figure 4 is an enlarged isometric, fragmentary view of the backing strip for the glass panel and the non-adhesive strip thereon.

l and 2 designate respectively sash frames for supporting glass panels 3, 4, each frame being formed with a channel 5 0r 6 angular in crosssection for receiving the margin of the glass panel 3 or I, each of these channels having a bottom I or 8 and 'an inner side wall 9 or III, the opposite outer side of the angular channel being open. The frames are shaped so that the side walls 9, ID are opposed to each spaced from 5 each other providing a channel between them for receiving a moisture-absorbing material II, as activated alumina. The sash frames I, 2 are preferably formed separate and secured together as a unit so that they are mountable, as a unit, 10 in a window opening.

As hereshown, the sash frames are provided respectively with peripheral circumferential flanges l2, l3 which are opposed to each other and located to the outward of the channel in 1 which the activated alumina II is placed. The flanges l2, 13 are here shown as in alinement with the side walls 9, III of the angular channels 5, 6- and a spacer I4 is located between the flanges l2, l3, this spacer being preferably of a heat 20' insulating material to prevent exchange of heat between the sashes. The flanges are secured together, as by screws l5, extending transverselytherethrough and the interposed spacer ll. The

frames are preferably made up of extruded metal 26 and are so shaped in cross-section as to facilitate the bending without undue distortion of the stock strips to form a rectangular frame or a frame with rounding corners.

Each sash frame' 5, 6 is also provided'with a ward of and parallel to the plane of the companion glass panel 3 or I. These grooves are for receiving a base flange of a retaining or glazing strip, each of which has a head portion ll or 36 I9 pressing toward, and here shown as directly against, the outer face of the margin of the companion glass pane 3 or 4. The retaining strips shoulder at 20 or 2| at the base of the heads on the frame at the outer side of the groove l6 or 40 I1, and the strip coacting with the'outer glass panel, that is, the panel toward the car structure is also provided with a lip 22 lapping over onto the outer facing of the car body. Also, the sash frame pn the outer side of the car body is formed 45 with ari extended flange 24 which laps the framing 25 around the window opening. 4

26 are brackets secured as by screws 21 to the frame 25 and extending transversely of the combined sash frames, and each bracket has an angular intumed portion 28 opposed to the peripheral flange l3 of the inner sash frame 2. The sash frames are secured in the window opening by screws 29 extending through these angular portions 28 and threading into the 86 peripheral flanges I 2, it of the sash frame. The action of these screws 29 clamp the-flange 24 tightly against the car body.

The moisture-absorbing material or activated alumina may be in granular form but is' preferably in a strip between the sash frames or the opposing inner side walls 9,10 of the bottom rail (Figure 3) of the sash'frames.

ber or a composition of rubber 'or cork, and after being in use, adheres to the glass, so that when it is necessary to remove the glass to replace the moisture-absorbing material or to replacea broken glass, the glass or the splinters thereof,in case of a broken glass, adhere to the backing and mutilate it when the glass is removed.

33 designates a flexible non-adhesive strip interposed between the margin of each glass pane securing them as a unit in the and the backing strip for the purpose of preventing mutilation, nicking or tearing of the backing strip. Usually, a cushioning strip of rubber or similar material 34 is interposed between the edge of each glass panel and the bottom I or 8 of the angular channel.

By the construction herein set forth, the sash frames can be mounted as a unit in a window opening, and either glass panel can be removed and replaced independently of the other for the purpose of renewing the activatedalumina or for the purpose of replacing a broken glass, and without demounting the sashes from the window opening. Further, the construction is particularly compact and economical for providing a channel for receiving the activated alumina and also mounting two sash frames together as a unit and window opening. What I claim is:

1. In a double window construction, the combination of opposing sasiiirames mountable as a unit in a window opening and shaped in crosssection to provide the opposing side wallsof a channel between the sash frames for receiving a moisture-absorbing material, each sash frame being formed with means for receiving a glass panel including removable members on the outer sides of said glass panels for holding the glass panels in the sash frames, said members being demountable to permit the individual removal and replacement of the glass panels and access to the channel for the moisture-absorbing material.

' -2. In a double window construction, the comis inter;

bination of opposing sash frames, each provided with an angular channel having a bottom and an inner side wall for receiving the margin of a glass panel, the open sides of the channels being presented laterally outward in opposite directions, the sash frames being shaped on their opposing sides to provide the opposing side walls of "a channel between the sash frames for receiving a moisture-absorbing agent, means for securing the sash frames together as a unit, and removable retaining strips for the glass panels mounted in the frames respectively and each having a head portion opposed to the-margins of the adjacent panel and forming the outer side wall of the adjacent angular channel.

3. In a double window construction, the combination of opposing sash frames, each provided with an angular channel having a bottom and an inner side wall for receiving the margin of a glass panel, the other open sides being presented laterally outward in' opposite directions, the sash frames being shaped on their. opposing sides to provide the opposing side walls of a channel for receiving a moisture-absorbing agent, the sash frame being formed with opposing peripheral flanges located to the outward of the last-mentioned channel, means for securing said flanges together, and removable retaining strips for the glass panels mounted in the frames respectively and having head portions opposed to the outer sides of the margins of the panels and forming the outer side walls of the angular channels.

4. In a double glass sash construction, the combination of opposing sash frames, each provided with means for supporting a glass panel and providing a backing on the inner face of the margin of the companion glass panel, and with a removable glazing strip coacting with the outer face of the margin of the companion glass panel,

the sash frames being shaped on their opposing sides to provide the opposing side walls of a channel between the sash frames for receiving a moisture-absorbing agent.

5. In a double glass sash construction, the' combination of opposing sash frames, each provided with means for providing a backing for the inner face of the'marginof" the companion glass panel, and with a removable glazing strip coacting with the outer face of the margin of the companion panel, a spacer arranged between the sash frames, the frames and spacer being arranged to provide a channel between the frames and opening into the space between the panels. for receiving a moisture-absorbing agent, and means for seouringthe sash sections and the spacer in assembled position.
