(Cl. 18S- 64) 2 Claims.
This invention relates to window structures for railway cars, buses, and `other enclosures, and has for its object a mounting for double glass panels including a resilientspacer between the` glass panels with means tending to spread the spacer laterally against the glass panels and keep the same snugly engaged therewith, and with the remainder of the mounting on the outer sides of the glass panels, under varying outside air pressure conditions, and thereby keeping the space between the glass panels hermetically sealed to prevent seepage of outside air into the space and the air from said space to the outside. When there is alow barometer or the outside air pressure is low, the glass panels tend to separate and the air seep from between the glass panels to the outside thereof. barometer or the outside air pressure is high, the glass panels are pressed toward each other and the air tends to seep from outside the glass panels to the space between them.
More specifically, the invention has for its object a mounting of resilient material which tends to follow up the movements of the glass panels occurring during low and high outside pressures, including a spacer between the glass panels, which also has the follow-up movement, or a spacer including wedging or spreader means, which means tends to spread the spacer laterally and keep it snugly engaged under all conditions with the margins of the glass panels.
It further has for its object a mounting for spaced apart glass panels, which mounting is of compressible resilient material, as rubber, or inchicles glazing strip and spacer portions of such material, together with means, as a shield, for protecting the exposed surfaces of the glazing strip and the spacer portions against deterioration from the sun and weather. It will be understood that the moisture taken into the pores of the rubber in cold weather freezes and tends to destroy the rubber, and also the sun in warm weather dries out the rubber.
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.

s I designates the sash which may be of any suitable form, size and construction'. A2 and 3 designate, respectively the glass panels. ing by which these panels are carried in the sash includes glazing strips 5, t coacting with the outer faces ofthe glass panels 2, V3 ,anda spacer I located betweenthe glass panels, the glazing strips and the spacer being of` resilient compressible material, as rubber, capable of having va give-and-take and a'follow-u'p movement.
The sashis formed with channels at 3 and 9 at its inner'and outer sides for receiving the base flanges It and I I `of the glazing strips.
'I'he spacer 1, in addition to the portion extending between the glass panels 2, 3,'includes a base flange I2 extending into a groove I3 in the sash and also laterally extending portions I I which extend across the edges of the glass panels. The spacer is also formed with a lengthwise channel for receiving a spreading or wedging means.
In the form shown in Figure 1, the channel I5 opens through a contracted entrance I5a through the inner face of the spacer and the wedging means is a cord I6 circular in cross-section, which is pressed into the channel I5 through the contracted entrance, and the spreader or cord I6 ts or interlocks in the channel to the inward of the contracted entrance. The cord is preferably of a resilient material, as rubber.
In the form shown in Figure 2, the construction is substantially the same as that shown in Figure 1, with the exception of the spacer. In this construction, the spreading means is provided on the sash I and the spacer I1 is provided with a channel I8 corresponding to the channel I5 but opening through the outer edge of the mounting means, and the portion of the spacer I I between the glass panels is formed hollow with the side portions thereof bowing or bulging outwardly. The wedging or spreading means is a rib I9 on the sash extending into the channel and tending to spread the spacer I'I.
In Figure ,4, another form of spacer, analogous to that shown in Figure 1, is shown including the portion 20 of the spacer, which portion ex- The mounttends between the glass panels and is provided with a V-shaped groove 2| opening through the inner edge of the spacer in which is pressed a wedge or spreader of resilient material.
In Figure 3, a different form of sash is shown for the glass panels including a body portion 23 seated. in a right angular channel in the sash 24 v and abutting at one side against the xed side 25 of the channel, and a glazing strip 26 on the other side of the sash. The body of the mounting is formed to receive the margins of the glass panels with the spacer 21 between them, and this spacer'is formed with a lengthwise channel opening through the inner edge of the spacer. The spacer is spread apart by a resilient metal wedge 29, V-shaped in cross-section, and tensioned to press the arms of the V formation outwardly.
The Wedge or spreader 29 is insertable in the channel of the spacer and is provided with outwardly aring lips which cover the exposed edge of the spacer with the exception of narrow lips at 30 adjacent the glass panels. The spreader 29 thus acts also as a shield to protect the spacer from deterioration. Also, the glazing strip 26 and the glazing strips 5, 6 (Figure 1) are covered by a sheath or shield 3l, usually of metal, this having a base portionv32 angular in crosssection extending into the groove of the frame in which the glazing strip is seated, and an outer portion 33 conforming t0 the outer contour of the bead or head of the glazing strip. Preferably, the bead or head is formed with a lip 34 lapping over the edge of the shield or sheath to cover the same.
In Figure 7, the spacer is shown as provided with a sheath 35 in the form of a channelshaped cap embracing a projecting margin of the spacer and of less width than the adjacent portion of the spacer, which presses against the glass panels. The sheath or cap 35 thus protects the exposed edge of the spacer against deterioration but does not modify the compressibility or resiliency of the spacer.
In any form of the invention, the spacer p0rtion of the mounting for the glass panels 2, 3 may, during installation, be placed under sufcient tension, so that it may spread or expand and contract to compensate for variations occurring during the uctuations in the outside air pressure. The remainder of the mounting, including the glazing strips, also give and take under the same conditions, so that the air space between the glass panels remain under the fluctuations in the outside air pressure, hermetically sealed.
Whatv I claim is:
l. A double window construction comprising a sash having resilient means for mounting a pair of spaced apart glass panels including a resilient spacer carried lby and interlocked with the sash and extending between the margins of the glass panels, the spacer being formed with a lengthwise channel opening through its inner edge, and wedging means located in the channel and spreading the side portions of the spacer to press against the margins of the glass panels, said wedging means being a strip of metal V-shaped in cross-section tensioned to spread the arms of the V formation laterally.
2. A double window construction comprising a sash having resilient means for mounting a pair of spaced apart glass panels including a resilient spacer extending between the margins of the glass panels, the spacer being formed with a lengthwise channel opening through its inner edge, and resilient wedge means of spring metal tting the channel, said wedge means having laterally extending lips covering the outer edge of the spacer to protect the same, the edges of the lips being spaced from the glass panels, whereby they are out of contact with the glass panels, thereby permitting compression of the spacer between the glass panels.
