5 Claims.

This invention relates to a window construction. More particularly. this invention relates to a window construction of thelgeneral character which is disclosed in the Nicholas E. Grifn Patent No. 2,199,562 dated May' 7, 1940, on a Window construction. The window construction which forms the subject matter of the aboveidentiied patent embodies a group of movable window panes or sections, which are movable abouthorizontally extending axes, intov and out of open and closed positions, and a vertically extending and horizontally movable weatherstripping member which is adapted to engage one side or vertically extending marginal edge portion of each of the window panes or sections so as to effect a Weather-stripping engagement between the vertically extending edge portions of the Window panes or sections when the latter are in closed position but so as to enable th'e window panes or sections to be moved into and out of open and closed positions.

An object of the present invention is -to provide, in a window construction of the general character which is ldisclosed in the above-identified Griiin Patent No. 2,199,562, a new and improved and simplied construction for moving the window panes or sections into and out of open and closed positions, and a new and improved and simplified construction for moving the weather-stripping member into and out of weather-stripping engagement with the window panes or sections.

Another object of the present invention is to provide a new and improved window construction of the character which is herein described and shown.

Other and further objects of the present invention will be apparent from the following description and claims and are illustrated in the accompanying drawings which, by way of illustration, show preferred embodiments and the principle thereof and what I now consider to be the best mode in which I have contemplated applying that principle. Other embodiments of the invention embodying the same or equivalent principles may be used and structural changes may be made as desired by those skilled in the art without departing from the present invention and the purview of the appended claims.

In the drawings,

Fig. 1 is a front elevational view of a window construction embodying the present invention;

Fig. 2 is a side elevational view of the window construction which is shown in Fig. 1;

Fig. 3 is an enlarged horizontal sectional view on line 3 3 in Fig. 1;

Fig. 4 is an enlarged horizontal sectional view of the window construction which is shown in Figs. 1 to 4, inclusive; and

Fig. 6 is a fragmentary front elevational view of a modified form of construction of the present invention.

A preferred form of the present invention is shown in Figs. 1 to 5, inclusive, and comprises a. window casement I0 which may be made in any suitable design and in any suitable material such, for example, as wood, metal and the like, inasmuch as the particular design of the window casement is not essential to -the present invention.

The particular form of the window casement I0, which is illustrated in Figs. 1 to 5, inclusive, of the drawings includes a box-like housing `v|| having a portion or side wall I2 which forms one side wall of the window casement I0, (Figs. 3 and 4). 'I'he window casement IIJ also lncludes a side wall I3, a top wall I4, and a bottom Wall I5, and the housing (Figs. 3 and 4) also includes a side wall I6 and end walls I1 and I8.

The window construction which forms the present invention includes a plurality of normally vertically extending window panes or sections I9, 20 and 2| each of which is mounted in a

frame

22, 23 and 24, respectively, these frames being made of any suitable material such as wood, metal or the like. Each of these

window frames

22, 23 and 24 has a vertically extending side rail or portion (25, 26 and 21, respectively) and these side rails or

portions

25, 26 and 21l are swingingly mounted on

trunnions

28, 29 and 30, respectively, for movement about their horizontal axes (Fig. 1) into and out of open and closed positions. Each of these

trunnions

28, 29 and 3|) has its outer end portionl iixedly mounted in the adjacent side Wall I3 of the window casement I0 and each of these trunnions 28 29 and 30 has the adjacentrail (25, 26 or 21) of the corresponding window frame (22, 23 or 24) slidably mounted th'ereon, for a reason which will be explained presently.

Formed in the inner surface of the vertically extending side wall 3 of the window casement I0 is a vertically extending groove 3| (Fig. 3) and a. portion of each of the side walls or

rails

25, 26 and 21 of the

Window frames

22, 23 and 24 is disposed in this groove 3| `when said window frames are in closed position, as shown in Fig. 3.

Formed in the side Wall I2 of the window casement I9 is a vertically extending slot 3|a (Figs. 3 and 4) and slidably mounted for horizontal movementI in this slot 3|a is a vertically extending weather-stripping member 32. Formed in the inner surface of this weather-stripping member 32 is a vertically extending weather-stripping groove 33 (Figs. 3 and 4) and a portion of each of the vertically extending side walls or

rails

34, and 36 of the

window frames

22, 23 and 24, respectively, is disposed in the vertically extending weather-stripping grooves 33 when the window panes are in closed position, as shown in Fig. 3.

Attached to the vertically extending side wall or rail 34 of the window frame 22, as at 31 (Fig. 1) is a horizontally extending shaft 38;

similar shafts

39 and 40 being similarly attached to the vertically extending side walls or

rails

35 and 36 of the

window frames

23 and 24, as at 4| and 42, respectively, (Figs. 1 and 4). Each of these shafts, 38, 39 and 40 is slidably and horizontally projected through an opening, as 43 (Fig. 4) which is formed in the vertically extending weather-stripping member 32.

shafts

38, 39 and 40 has a squared outer end portion (Fig. 2) and mounted on the squared outer end portions of these shafts are

gears

44, 45 and 46, respectively. These

gears

44, 45 and 46, respectively, are located in the box or housing and mesh with

worms

41, 48 and 49 which are mounted on a vertically extending operating rod or shaft 50 which is slidably mounted in the housing II for vertical movement therein. A compression spring 5| is arranged upon the lower end portion of the vertically extending operating rod 50 and tends normally to urge the vertically extending operating rod or shaft downwardly.

Fixed on each of the

shafts

38, 39 and 4D, outwardly of the weather-stripping member 32, s a collar 61, the purpose of which will be described hereinafter.

Splined on the vertically extending operating rod 50, adjacent the lower end thereof, (Figs. l'and 2) is a beveled gear 52 and this beveled gear 52 meshes with a beveled gear 53 (Figs. l and 2) which is mounted upon a horizontally extending operating or crank shaft 54 which is arranged adjacent the bottom wall I5 of the window easement I0; this operating or crank shaft 54 carrying a manually operable handle or crank 55 which is arranged adjacent the bottom of the window and is accessible from the inner side thereof.

Mounted on the vertically extending operating rod or shaft 50 (Figs. 1 and 2), at spaced intervals thereon, are two

collars

56 and 51 and each of these collars is provided with a

groove

58 and 59, respectively. Working in the groove 58 of the collar 56 are two pins 69 each of which is mounted on an arm of 'i bell crank lever or yoke 6|. Each of these bell crank levers or yokes 6| is pivotally mounted, as at 62, on a bracket 63 which is mounted on the vertically extending side wall I2 of the easement I0 and the bell crank levers 6| are pivotally connected by an angled portion 64 of a link 65. This link 65 has a second angled end portion 1| which is rockably mounted in a bracket 66 which, in turn, is mounted on the vertically extending weather-stripping member 32, on the outer side thereof (Fig. l). Similar parts bearing the same reference numerals, followed by the letter "a, are associated with the lower collar 51 (Figs. 1 and 2).

The operation of the new window construction Each of these which is shown in Figs. 1 to 5, inclusive. and which has been described hereinbefore is as follows:

Operation When the window panes or sections I9, 20 and 2| are in their normal or closed position the parts are disposed in the position which the window pane or section I9 and its frame 22 and associated parts are shown in Fig. 3, with the outer portions of the vertically extending

side rails

25, 26 and 21 of the

window frames

22, 23 and 24, respectively, projecting into the vertically extending weather-stripping groove 3| which is formed in the side wall I3 of the window Casement I0 and with the outer end portions of the vertically extending side rails or

walls

34, 35 and 36 of the

window frames

22, 23 and 24 projecting into the weather-stripping groove 33 which is formed in the vertically extending weather-stripping member 32.

However, when it is desired to open the window panes or sections I9, 2|) and 2| this is effected as follows: The operating crank or handle 55 and its supporting shaft 54 are rotated and this movement of the shaft 54 acts, through the

beveled gears

53 and 52, to rotate the vertically'extending operating rod 50 and the

worms

41, 48 and 49 carried thereby. When rotary motion is thus first imparted to the vertically extending operating rod 50 andv its attached

worms

41, 48 and 49 the Worms 41, 48 and 49 (while in constant mesh with the

gears

44, 45 and 46 on the

shafts

38, 39 and 40) do not function at flrst to rotate the

gears

44, 45 and 46 and their supporting

shafts

38, 39 and 40, respectively, due to the fact that the outer edge portions of the

rails

34, 35 and 36 of the

window frames

22, 23 and 24, respectively, are seated in the vertically extending weather-stripping groove 33 which is formed in the weather-stripping member 32, thereby restraining the

window frames

22, 23 and 24Aand the

shafts

38, 39 and 40 and the

gears

44, 45 and 46, respectively, mounted thereon, from rotation. Accordingly, when rotation is flrst imparted to the vertically extending operating shaft or rod 50 and the

worms

41, 4B and 49 mounted thereon this rotation of the

worms

41, 48 and 49 4which are in mesh with the

gears

44, 45 and 46 but are unable at this time to rotate, causes the vertically extending operating rod or shaft 59 to be lowered somewhat, in the direction of the action of the spring 5| which normally urges the vertically extending operating rod or shaft 50 downwardly. This downward motion of the vertically extending operating rod or shaft 50 acts, through the

collars

56 and 51 and the bell crank levers 6|, 6|a and the

links

65 and 65a, and associated parts, to pull the weather-stripping member 32 away from the window panes or sections I9, 20 and 2|, and their

frames

22, 23 and 24, respectively, thereby moving the grooved portion 33 of the weather-stripping member out of weather-stripping engagement with the

side rails

34, 35 and 36 of the

window frames

22, 23 and 24, respectively.

During this movement of the weatherstripping member 32 the same engages the collars 61 on the

shafts

38, 39 and 4|) (which are rotatable in the openings 43 which are formed in the weather-stripping member 32) and this engagement of the weather-stripping member 32 with the collars 61 on the

shafts

38, 39 and 40 moves the window panes I9, 20 and 2| and their

frames

22, 23 and 24, respectively, from left to right as seen in Figs. 1 and 3, thereby sliding the

side rails

25, 26 and 21 of the

window frames

22, 23 and 24, respectively, out of weather-stripping engagement with the weather-stripping groove 3|, which is formed in the side wall I3 of the window easement I0, much in the same manner as this result is accomplished in the above-mentioned Griiiln Patent No. 2,199,562.`

However, as soon as and when the grooved weather-stripping member 32 has been moved out of engagement with the

side rails

34, 35 and 36 of -the

window frames

22, 23 and 24, respectively,

and the

opposite side rails

25, 26 and 21 of

thek window frames

22, 23 and 24, respectively, have been moved out of weather-stripping engagement with the groove 3| in the side wall I3 of the window easement I0, so that the window panes I9, 20 and 2| and the

window frames

22, 23 and 24 and the weather-stripping member 32 assume the position in which the window pane 20 and its frame 23 are shown in Fig. 4, further rotary motion imparted to the vertically extending operating shaft 50 and the Worms 41, 48 and 49 thereon, (by rotation of the crank 55, crank shaft 54 and

gears

53 and 52, in the manner described above), causes the

gears

44, 45 and 46 and their supporting

shafts

38, 39 and 40, respectively, to be rotated, and this rotation of

thevshafts

38, 39 and 40 swings the window panes or sections I 9, 2|! and 2| and their supporting

frames

22, 23 and 24, respectively, into open position, as indicated in dotted lines in Fig. 2.

When it is desired to close the Window panes I9, 20 and 2| this may be accomplished by rotating the crank 55 and the crank shaft 54 in a direction opposite or counter .to that in which the crank 55 and the crank shaft 54 are rotated to open the window panes, and this rotation of the crank shaft 54'acts, through the

gears

53 and 52, to rotate the vertically extending operating rod or shaft 50 and the

Worms

41, 48 and 49 which are mounted thereon, thereby rotating the

gears

44, 45 and 46 and their supporting

shafts

38, 39 and 40, respectively, in a direction to swing the window panes I9, 20 and 2| and their supporting

frames

22, 23 and 24, respectively, into closed position, whereupon further rotation of the vertical `operating shaft 50 and the Worm

gears

41, 48 and 49 which are mounted thereon acts, through the

grooved collars

56 and 51 and the yokes or bell crank levers 6I and lila and attached

links

65 and 65a, to move the weather-stripping member 32 into weather-stripping engagement with the

side rails

34, 35 and 36 of the

window frames

22, 23 and 24, respectively. It will be noted, in this connection, that as the weather-stripping member 32 engages the

side rails

34, 35 and 36 of the

window frames

22, 23 and 24, respectively, it slides these window frames and the window panes mounted thereon (from right lto left, Fig. 4, into the position in which they are shown in Fig. 3) thereby moving the

side rails

25, 26 and 21 of the

window frames

22, 23 and 24, respectively, into weather-stripping engagement with the weatherstripping groove 3| in the side wall I3 of the window casement I0.

It will be noted, in this connection, that the spring 5| exerts a slight downward pressure upon the vertical operating rod shaft 50 and this pressure aids in effecting the immediate Withdrawal of the weather-stripping member 32, when the windows are being opened, and, when the crank 55 is rotated in the reverse direction to close the windows, the downward action of the spring 5| tends to maintain the rod 50 from creeping upwardly and prematurely moving the weatherstripping member 32 into binding engagement with the

window frames

22, 23 and 24.

A slightly modified form of the new window construction is shown in Fig. 6 and all parts embodied therein which correspond to or are similar to parts embodied in the form of the invention shown in Figs. 1 to 5, inclusive, bear the same reference numerals, followed by the letter 'I'his modified form of construction is substantially similar to the-form of construction which is shown in Figs. 1 to 5, inclusive, except that in this modified form of construction the shaft 54h is extended horizontally in a direction parallel to the front surface of the window, instead of at right angles thereto, as is the shaft 54 in the form of the invention which is shown in Figs. 1 to 5, inclusive. Moreover, in this form of the invention the shaft 54h is extended to a point which is approximately the vertical center of the window casement, and a second or crank shaft 68, carrying a crank 55h, is extended at right-angles to the shaft 54h, these two shafts 54b and 55h being operatively interconnected by a bevel gear 69 on the crank shaft 68 which meshes with a bevel gear 'IIJ on the shaft 54h.

While I have illustrated and described preferred forms of construction for carrying my invention into effect, these are capable of variation and modification, without departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.
