My invention is concerned with improvements in double glass sash construction of the t pe More specifically, it is an object of my invention to providea double glass sash construction comprising a pair of generally rectangular rim members, which are positioned to form a frame having a channel-like recess for receiving and clamping the edges of the glass panes, Tastening elements to hold the rim members in clamping position and resilient separator and glazing means positioned at the edges of the panes for spacing the edges of the panes from each other and from the rim members, wherein the rim members, the separator and glazing means are shaped and positioned to accomm'o date panes of varying thickness.

It is a further objbt f invention t6 pro= vide a double glass sash 'of the type described which when installed in an aperture in a'vhi'cle wall will provide a window which is hermetically sealed irrespective of commercial variations in the thickness of the glass and in which the frame forming rim members are positioned between the inner and outer vehicle wall members with theglazing strips covering the normally exposedsurfaces of said rim members. 7

It is another object of. my invention to 'pro vide a novel sash construction which may be economically manufactured and which is readily and easily assembled and installed ina sash opening.

These and other objects will be apparent from the description of the preferred form of my -in= vention,- which is shown, by way of illustration, in the accompanying drawings, wherein:

Fig. 1 is a face View of a double 'glass'sash com structed in accordance with my invention;

Fig. 2 is a .perspective sectional view through one of the walls of the sash;

Fig. 3 is a transverse sectional view taken on:

the line 3-3 of Fig. l;

Fig. 4 is a perspective sectional view through one of the rim membersiof the frame;

2 Claims. (Cl. 189 64) Fig. 5 is a perspectivesection'al view through one of the rim-connection members;

Fig. 8 is a perspective sectional view through ee edge spacing member; and i Fig. -7 is a perspective sectional view throng one of the glazing strips. i

The preferred form of my invention, as illustrated in the diawing com rise a name 'i'orlnd by complementary rim members 1 0 and I11, which are generally rectangular and which *fgifind continuously around the-edges of the two glass panes i2 and I3. a l

The rim members 10 and "l I are provided with inwardly extending flanges 14 and 1 5 and out wardly extending flanges l6 and M, respectively. They are also provided with short laterally directed web's l8 and I 9 andshort outwardly directed flanges 2'0 and 2] at the confronting edges of the webs 18 and 19. The flanges Ill and 2| are spaced apart slightly in generally parallel relation to the median plane of the sash. The flanges 1-6, H and 20,21, together with the webs l8, 19 form outwardly directed pocketstto receive connecting'bmcks 22.

The connecting blocks 22 "are provided on the four sides of the sash butdo not extend around the curved cornersof the same as indicated in Fig. 1. The connecting blocks 22 (F1915) "corn prise a base portion 23 and inwardly extendin Side projections 24, 25; which fbfiil Central groove 25. The inwardly extending side m jections 24 and 25 are received in the pockets formed between the flanges I16, and [1, 21 0!. the rim members 10 and *M. The flan e members 2o 'and 2l of the rim members wand l I are we cei v'ed in the groove z'e of the connecting block's 22. The inner faces 2! and 28 of the Side ploj ections 24, of the-connecting block's -22 are in abutting, olainbing relation with the falh'g 'sbits 29 and 30 presented'by the short flanges L20 and 2|.

The glass panes lz and rs are separated "at their "edges by a spacing strip or separator 31; which is preferably of resilient materim such &8 rubber. The strip a l (Fig. 1:) is inverted 'T- shaped in cross-section providing a base portion 32 having late-rally extending flanges 33; 81, whicl i' are sated between the outer edges or "the panes 1 2 and I3 and the webs and I9 or rim members 10 and 11. stem portion as is cositioned between the names l2 and :13 and is pro vided with angularly directed rib-llke projections 36 on each face which engages the sum face of thecpanes. When "the strip isclamped in .position rbetweenfxthe panes. t2 and 13 (:Fig. 3)

the ribs 36 engage the surface of the panes some distance inwardly from the edge thereof.

The panes I2 and I3 are separated from the flanges I4 and I5 of the rim members I and II by means of glazing strips 31 and 38 as shown in Figs. 2 and 3. As illustrated particularly in Fig. 7, glazing strip 31 is generally U-shaped in crosssection and is provided with an inner leg 39 which is somewhat shorter than the outer leg 40. A recess M is formed between the legs 39 and 40 which is adapted to receive the flange I of the A lateral groove or, recess 42 rim member I I.

i the rim members.

held in clamping relation with the flanges '20 and is provided in the leg 39 for cooperation with a laterally extending ridge or1ip'43 on theflange I5 of the rim member II to position the strip 38 in interlocking relation with the rim member I I. The inner face of the leg 39 of the glazing strip 38 is provided with angularly outwardly projecting ridges 44, which are adapted to engage the' surface of the pane I3 at a point spaced from the edge of the pane, The ridge members 44 are of the samecharacter as the ridge members 35 onthe .spacing strip3l. When the sash is symmetrical as illustrated in Fig. 1 the glazing strips 31 and 38 may, of course, be identical in construction.

Theribs 36 on separator strip 3I and the ribs 44. on glazing strips 3'! and 38 are initially angularly projecting, as shown in Figs. 6 and 7, and as indicated in dotted lines in Fig. 3. When the structure is assembled as shown in solid lines in Fig. 3, with the glass panes in position and the frame members I0 and II clamped together by the members 22, pressure is applied between the engaging portions of the members and the ribs 36 and 44 are flattened or distorted, so that the pressure is equalized. The panes I2 and I3 are firmly clamped between the flanges I4 and I5 of the rim'members I0 and II by engagement of ridgemembers36 and 44 with the surface of the glass and the pressure on the edges of the panes of glass is applied at points inwardly of such edges throughthe ridge members 36 and 44. With this construction they are better able to stand the sudden shocks and stresses which they are frequently subjected to in use. 7 4 The outer surface 45 of the bight portion of the U-shaped glazing'strip 3'I slopes outwardly and merges with the outer face 46 of the leg 40. The'outer face 46 of the leg 40 is provided with angularly outwardly projecting ridge members 41.

The-glazing strips 3! and 38 serve the dual purpose of spacing the glass panes I2 and I3 from the clamping flanges I4 and I5 of the rim members I0 and I I and also of spacing the entire sash construction between the conventional flashing 48 and 49 (indicated in dotted line in Fig. 3) on theinside and outside of the vehicle wall in which the sash is mounted, the ridge members 41 engaging the inner surface of the flashing, as

illustrated.

The glazing strips 3'! and 38 cover the flanges I I-and I5 of the rim'members ID and II so that there are no exposed metal frame surfaces when the sash is installed'in the vehicle wall. The metal frame. members I0 and II, the flashing 48 and 49 and the glass panes I2 and I3 are completely insulated from each other by the separator strip 3| and glazing, strips 31 and 38 to provide an hermetically sealed window having low heat conductivity irrespective of commercial variations in the thickness of the glass panes I2 and I3. Y

In manufacturing the improved sash two assemblies may first advantageously be made-one '2I by the resiliency of the glazing strips after assembly of the sash members.

The connecting blocks 22 may be provided with spaced threaded holes 50, which are adapted to receive in threaded engagement a tool or threaded member by means of which they may be withdrawn from engagement with flanges 20 and 2! when it is desired to disassemble the sash. The side projections 24 and 25 of connecting members 22 maybe beveled at 5 I to facilitate their entry between the rim members It and II. The width of the central groove 26 of the connecting members 22 may be varied whereby the sash may be adjusted to, accommodate panes of glass of materially different thickness without any alteration in the size or shape of the frame members Ill and II, the spacing member 3| or the glazing strips 31 and 38.

The glazing strips'and spacing member for the lass may be made of any resilient material but they are preferably formed of molded rubber. The rim members I8 and II and the connecting members 22 may be made of any appropriatelnaterial but are preferably formed of light metal such as extruded aluminum. 7 V

While I have referred to specific materials and details of construction, it will be understood that other materials and details of construction may be used within the scope of my invention.
