Application December 31, l1953, Serial No. 401,628

10 Claims. (Cl. 268-404) This invention relates to a window. operator combination in which the sash may be moved to its various positions by means of a mechanism wherein the forces employed to effectuate the movements necessary to adjust the sash are exerted upon the. sash' through the medium of ilexible but substantially longitudinally non-compressible rod or equivalent member such as a wire, and through which the forces are transmitted in directions, longitudinally of said member.

One advantage of this invention lies in the fact that the necessity for such elements as cranks, levers, gearing and similar force transmitting elements between the sash and the actuator is reduced to the minimum with the result that the forces applied to open and close the window sash are converted intorthe maximum available power.

Another advantage of this invention lies in the fact that the device in which it is embodied is relatively simple, sturdy, easily installed and maintained and will consume a minimum of space. s

In addition tothese advantages a device embodying this 'invention will not only operate to open and' close the window sash when it is actuated, but Vwill also maintain the sash in its open arid closed positions and additionally may be used to forcibly set the sash up against the weather stripping with a weather stripping compressive force.

. Other advantages will appear from the description of the embodiment of the invention illustrated in the drawings and described in the specification.

While the invention is Lapplicable to windows having sashes of different types, Iv shall describe it in connection with what is currently known as an awning window and itis thus illustrated in the drawings.

In these drawings: f i Y Figure l is a face View of an awning typewindow with one light;

Figure 3 is a horizontal sectional view on line 3 3 of Figure 1 looking in the direction of the arrows;

Figure 4 is a vertical sectional View on the linev 4 4 of Figure 1 looking in the direction of the larrows but with the sash partly open; ,Y

Figure 5 is an enlarged viewA of one of the operator members and a portion of the actuator taken on line 5 5 of Figure 4; g

Figure 6 is a vertical sectional view on line 6 6 of Figure 5 looking in the directon'of the arrows;

Figure 7 is a horizontal sectional View on the line 7 7 of Figure 5 looking in the direction of the arrows;

Figure 8 is a horizontal sectional View on line 8 8 of Figure 5 looking in the direction of the arrows;

Figure 9 is a sectional View on line 9 9 of Figure 8 looking in the direction of the arrows; and

Figure 10 is a sectional view on line 10 10 of Figure 2s looking in the direction of the arrows.

The window to which the operator of this invention is applied and which is depicted in the drawings for illustrative purposes; comprises a frame having a header 1,

HCC

a sill 2 and jambs 3 as illustrated in Figure l. Each of the jambs 3 is provided with a longitudinal, vertically extending chamber 4 as shown in Figure 3. The header 1 is provided with a longitudinal, horizontally extending chamber 5 and the sill is provided with a longitudinal, horizontally extending chamber 6 as illustrated in Figure 4 of the drawing.

The header maybe provided with compressible weather v stripping such as 7, the sill with a similar weather stripping such as 8 and the jambs with a weather stripping such as 9, all of which are so arranged as to be contacted by and compressed by the sash when the latter is moved into its closed position.

This sash is mounted as follows: In each of the chambers 4 in the jambs a plurality of guide rollers 9' are f mounted on the jamb. An elongated slide 10 is mounted on these guide rollers for vertical movements in upward and downward directions.

Adjacent the lupper end of each slide the sash 11 is pivoted at 12 to swing about these pivots into opened and closed positions. l

To each side of the sash a stay-bar 13 is pivoted at 14, the stay-bar being pivoted also at 15 to the jamb.

Thus when the slides are moved downwardly the sash will be moved toward its open position about the pivots 12 and when the slides are moved upwardly the sash will be moved toward its closed position. This is because the pivots 12 move vertically with the slides while the pivots 15 have no such movement.

- In order that the sash may be moved to its open position and to its closed position, maintained in such positions and sealed against the weather stripping around its entire perimeter, I have provided the following mechamsm:

A relatively stijf, resilient and substantially non-compressible longitudinally operating member such as a wire 16 or its equivalent, is attached to each of theV slides 10 at a convenient point such for` instance as at its upper end `as shown in Figure 4 by such means as will hereinafter be described. VThese operating members 16 are located within the chambers 4 of the jambs and extend downwardly towardk the sill insuibstantially rectilinear directions. They also follow rectilinear directions within the chambers 6 of the sill toward the center thereof. Between the two rectilinear portions of each operator lthe operator follows a curvilinear path. The two rectilinear portions are indicated bythe reference numerals v17 and 18 and the curvalinear portion by the reference numeral 19.

The ends of these operating members 16 terminate adjacent each other preferably near the center of the sill and in overlapped relation.

When the rectilinear portions 18 are moved longitudinally outwardly, i. e. toward the respective jambs, the vertical rectilinear portions 17 will be moved upwardly, the force being applied through the curvilinear portions 19, with the result that the slides 10 will be moved upthe same time to providea protective covering, I have l provided the following: Y

Each of the operator members 16 is housed within a relatively rigid tubular member 20, -a portion 21 ofwhich is located within and extends longitudinally of the sill chamber 6 and another portion 22 of which is located within and extends longitudinally of the chamber 4inV a jamb.

These two portions of the tube are substantially rectilinear andunlited by an integral curvilinear portion Z3. These three portions of the tube `determine the directions of the operating member 16,

The tube is made rigid with the window frame by suitable devices such as indicated at 23 in Figures 3, 4 and 5. It may be made integral with the window frame.

The -operating member 16 is encased in a sheath and force transmitting member 24 which is preferably in the form of a helically coiled spring with insubstantial compressibility. This sheath, while snugly 'fitting within the tubular member 20, is capable of free sliding movement therewithin. The inside diameter of this sheath is such that the operating member 16 ts snugly therein and is thus prevented from having undesirable lateral flexing during operation.

A tubular extension 25 is `mounted on and envelopes therupper end of each of the tubular members and is freely movable `on the tubular member. This exten# sion is secured to a bracket 26 which is provided with a bearing member 27 and is secured at `28 to the adjacent slide 10. The bearing member 27 1islprovided with a bore 29 through which a rod 30 freely extends; To the lower end of this rod Athe operating member 16 is ixedly attached. The upper end of the rod is threaded as at 31 and is provided Vwith a locking nut 32; An adjusting nut 33 is 4in screw threaded engagement `with this rod and is provided `with a depending sleeve 34 which is iixedly secured `to the extension 25 of the tubular member.

Inasmuch as the tubular member is tixedly secured to the frame of the window `as'at 23', the adjustment of the nut 33 will adjust the extension 25 of the tubular member on the main body portion of the latter in which i position yit `may be locked by the lock nut 32.

Thus when the operator is Ioriginally installed the relative positions ofthe operator elements in respect to each other `and in respect to the sash on both sides of the window may be adjusted so that in subsequent operation equal forces willbe applied to both sides of the sash,

ber is such as to permit this block to move sufficiently for the opening and closing of the window sashes.

The other of the two operating members 16 is provided with a similar block similarly mounted. The sheath 24 freely abuts the 'block 46 at its lower end at 24' and also freely abuts the lower end of the rod at its upper end at 24 so that when the block 46 is moved longitudinally within the tubular member 20 the oper- -ating member 16 and the sheath 24 will move as a unit with the block and with the rod 30. Rigidly connected to each block 46 is a coaxial rod 47 which is provided with a plurality of spaced abutments 48 which are rigid with the rod. The inside diameters of the portions 21 of the tubular members 20 -of the extensions 20' and of the openings 40,411,42 and 43 are substantially the same and the diameters of the labutment members 48 are only sufficiently less than the inside diameter of the tubular members and they openings to permit free longitudinal movements of the abutment members within the same. As will be noted from Figure 9 of the drawing, the

i two operating members 16 in effect overlap, but as disclosed in Figure 5 of the` drawing, terminate short of the ends of the extensions 20 of the tubular members 20 so that the operating vmembers may have freedom of movement in the tubular members longitudinally of themselves. t

In order that the operating members may be moved longitudinally to open and close the sash simultaneously,

l I have provided the following mechanism: An actuator thus insuring true -opening and closing ofthe sash ony the pivots vwithout any distortional tendency.

In order that the operators 16 may be actuated to move in both directions longitudinally of their long` axes, I 'have provided the following mechanism: a housing '35 -is `provided `and may be mounted on the sill in 4such a position as indicated in Figure l of the drawing. This housing is constituted preferably by a lower housing member 36 and a superimposedupper housing member 37 which are secured rigidly together, the lower member being provided with a recess 38 and the ruppermember with a recess 39 which together forma chamber in the housing. The

lower housing member

3,6 is provided with aligned openings `40 and 41 which extend through the wall of the lower housing -member `36. `A secondpair of aligned openings 42` and 43 which are substantially v parallel to the first mentioned openings extend through the wall of theV housing member 36 as illustrated in `Figure 9 of the drawing. An end of ,one of the tubular members 20 is secured to the housing as at 44 in ,alignment with the opening 40 while an end lof the `other tubular member` 20 which Ais aligned with the opening V45 is secured 'to thehousing as at 45. v

Extending from thefopening 41 is an aligned extension 20 of the tubular member 20 which is aligned with the opening 41and extending from the opening 42 is a similar `extension 20'.

One of .the operating members 16 is rigidly secured to a block 46 which-is mounted within the tubular member 20 located within the sill of the window. The diameter of this block 46 is such that it may have free longitudinal movements within 'the tubular member and the length of itherectilinear portion 21 of the tubular memis locatedwithin the housing 35. A disc 49 somewhat in the `form of asprocket is located within the recess 38 of the chamber of the housing 35.` This disc or sprocket is provided with projections 50 and recesses 51, the projections being substantially radial and being bifurcated as shown in Figure 8 of the drawing for the reception of the rod members 47. `The projections 50 are adapted to extend into the spaces between the abutments 48 and to engage the same so that upon rotation of the sprocket 49 the portions of the operating members 16 located within the chamber yof the sill will be moved in opposite directions thus `moving the vertical portions of the 4operating members either upwardly or downwardly depending upon the direction of rotation `of :the sprocket 49. During the engagement of the projections 50 with the abutments 48 the latter will successively seat Within the recesses 51 of the sprocket as disclosed in Figure 9 of the drawing `as the sprocket is rotated.

Formed rigid with this sprocket member 49 is a gear 52 which is spaced yfrom the sprocket member by a hub 53 and is located in the recess 39 of the chamber ofthe housing 35, the gear being coaxial .with the sprocket. A cooperatingworm 54 which is engaged with the gear 52 is suitably mounted in bearings within the `housing 35 and is provided with an operating handle 5S `which is accessibleat the inside of the Window. It may be here pointed out that the gear 45 is in the form of a helicalL gear which insures through the engagementof the worm 54, the maintenance yof the ysprocket 49 in its various positions of rest.

When the operating handle 55 vis actuated ,the worm 54 will rotate the helical gear 52 and through the hub 53 the sprocket member 49 will be rotated in a direction dependent upon the `direction of rotation of `the worm 54. Because of the engagement of the sprocket member 49 with the abutments 48, the rotation of the sprocket member in one direction will cause the rods 47 t0 move outwardly toward the jambs. This movement of the rods will move the blocks 46 within the tubular members 20 and because of the presence of the sheath 24 and the operating member 16 and the abutment of the sheath against the block 46 and the rod 36 on each side of the Window the bracket 26 will be moved upwardly,` the securement of tbe'brackct 26 on each side of the window to the adjacent slide at 28 eiectuates the upward movement of the slides and consequently closes the sash.

When the operating handle 55 is actuated in the opposite direction the movement of the operating members 16 will be in the opposite direction and as a consequence the slides 10 will be drawn downwardly thus causing the opening of the sash.

It is here pointed out that when the actuator is operated to move the vertical portions of the operating members 16 upwardly the force will be transmitted to the slides 10 not only by these operating members 16 but also by the sheaths 24, the two elements on each side of the window thus forming a compound operating member during such vertical movement.

Because of the sturdiness of the construction, pressure may be applied to the operating handle 5S near the end of the closing movement of the sash so that the weather stripping will be compressed to seal the sash. The sash will be held in this closed position by the locking action of the helical gear and the worm with which the handle 55 is provided.

Each operating member 16 may be made of a relatively small diameter wire of steel but the wire may be made of various other materials having lateral flexibility and substantially no extensibility or compressibility longitudinally of itself. Moreover the sheath 24 may be made of metal or of other desirable materials which will not only guide the members 16 and assist in the movements of the slides but will also dampen any noises that may result from the movements of the operating members.

While I have illustrated and described the operator as applied to what is currently known as an awning window, it is to be understood that with certain modications it may be adapted to operate windows of other types, such as Casement windows and double hung windows, by way of example.
