6 Claims.

'I'his invention relates to' window operators for pulling the window, and further, which holds the window in any desired position between or at its limits of movement without resorting to supplementary holding devices. It is another ob- .lect of this invention to provide an operator of the above nature which takes up a minimum amount of room in the window opening, and yet which is suiiiciently extendable to completely open the Window.

Other objects will be in part apparent and in part pointed out hereinafter.

The invention accordingly consists in the features of construction, combinations of elements, and arrangements of parts, as will be exemplified in the structure to be hereinafter described, and the scope of the application of which will be indicated in the following claims.

In the drawings, in which are shown several embodiments of my invention:

Figure 12 is a sectional elevation taken the une lzflz of Figure 9.

Similar reference characters refer to similar along parts throughout the various Views Aof the drawings.

Referring iirst to Figure 1 of the drawings, a

Vbase plate l5, which is adapted to be secured to the sill of the window opening has mounted'there on a bottom bar I6 of the window frame, and these two parts have secured thereto one element il of a hinge generally indicated at i8. Hinge 58 as shown is of the type described in detail in our United States Letters Patent No. 1,955,653, and further is of the type provided for a -projected easement window. Hinge I3 accordingly includes a movable element IS to which is secured the bottom sash bar Z of the window sash.v

Also secured to base plate l5 is an operator generally indicated at 2l, which includes relatively extensible members generally 'indicated at 22,V ywhich are attached to sash bar 2li. Operator 2l also includes a manually rotatable crank or the like 23 which upon operation swings the window sash.

Operator 2| comprises a base 24 secured by screws 25 to base plate l5. A web 26 (Figure 2) extends upwardly from base 24 and is joined to another web 2l also extending upwardly from base 2li. 'I'hese two webs support a journal or housing 28 whose axis extends diagonally with respect tol web 21 and base`24 of the operator.

Housing 28 rotatably carries a shaft or the like (not shown) to one end of which is attached crank 23 (Figure 1) and to the other end of which is attached one element or fork of a universal joint, the other element 30' of which is secured to the inner end of the relatively extensible members 22. l

Members 22 include a tubular interiorly threaded member 3l which threadably receives a screw 32 the outer or exposed end of which is pivoted at 33 to a lug 361A or the like secured to ksash bar 23. It will now appear that upon operation of crank 23, tubular element 3| will be rotated by reason of its connection to the crank through the universal joint elements 29 and', and in accordance with the direction of rotation of element 3|, screw 32 is extended or projected from` the tube or is drawn thereinto, as the screw is constrained against rotation by reason of its attach-l ment to lug'34. Thus, the only possible movement of screw 32 with respect to tube 3l is axial, although both elements are pivotable with respect to operator 2l and accordingly base plate l5.

Assuming that element 3| rotates in the direction to draw screw 32 into element 3l, sash bar 20 is swung clockwise until it reaches the dotted line position shown in Figure l. Reverse rotation 3| and 32, supplementary sash locking devices are unnecessary as the sash is effectively locked in any desired position and furthermore rattling of the sash in its opened, closed, or in any inter mediate position is precluded as there is little or no play in the window operating elements 2| and 22 or in the hinge i8. Also, by reason of the telescoping relationship of elements 3| and 32, these elements occupy but a limited amount of space in the window opening, and aside from their efficiency in operation, are both sturdy and neat in appearance.

Referring now to the modied form of operator generally indicated at 35 in Figure 3, a base 36 carries a substantially crescent-shaped or U- shaped support 31 to which is secured in any suitable manner a curved wall portion 38 (Figure on the top of which is mounted a cover plate 39. A web 49 (Figure 3) is secured to support 31, wall 36 and top 39, and through this web and top extends a journal 4| or the like (Figures 3 and 4) whose axis is diagonal to the plane of the web and to the plane of bottom or base 36. As shown in Figure 5, journal 4| opens into the enclosure between top 39 and base 36 (Figure 3) and rotatably carries a split shaft generally indi- I cated at 42 in Figure 4. Shaft 42 comprises a pair of elements 43 and 44 joined by a key 45 or the like. Shaft element 43 includes a reduced portion 46 which extends into the shank of a crank 6|), by which the operator is manually 1 operated. Shaft element 44 has connected thereto one end 41a of a exible cable 41 which extends into the enclosure between base 36 and top 39 of the operator.

Base 36 (Figure 4) has a circular groove 48 and top 39 has a similar registering groove 49, in which a cylindrical housing 50 is rotatably mounted. That portion of housing 59 (Figure 5) which is exposed, i. e. which lies outside of curved wall 38, is formed with a tubular projection 5| adapted to journal a rotatable stud 52 having a central core 53 in which the other end 41h of flexible cable 41 is secured as by a pin 54. The inner end of stud 52 hasva shoulder 55 which abuts the inner end of projection 5| to prevent displacement of stud 52 to the right as viewed in Figure 5. The outer end of the stud has a reduced threaded end 56 about which a nut 51 is threaded against the outer end of projection 5|; nut 51 and shoulder 55 preclude axial displacement of stud 52 with respect to projection 5|. Threaded end 56 of stud 52 has threaded therein the inner end of an elongated tubular element 58 similar to element 3| shown in Figure 1. This element 58 is interiorly threaded and threadably receives a screw 59 similar to screw 32 shown in Figure l. The outer end of screw 59 (Figure 3) is adapted to be secured to the Window sash as described with respect to screw 32 (Figure 1) to effect opening and closing of the sash upon actuation of the operator.

Operator (Figure 3) is adapted to be secured to a base plate such as base plate |5 (Figure 1) so that upon rotation of crank 6|] (Figure 4) flexible cable 41 turns to rotate element 58. As element 58 rotates, screw 59 (Figure 3) is extended from or drawn intol element 58 to swing the window. As the window swings, however, elements 58 and 59 also swing, and accordingly cylindrical housing 59 rotates in its grooves 48 'element 3| (Figure 1).

and 49 (Figure 4). This rotation is possible by reason of the flexible nature of cable 41 which assumes various positions within housing 50 (Figure 5) as the housing follows the swinging movement of element 58 and screw 59.

Generally indicated at 6| in Figure 6 is another modication of our operator. This form includes a base 62 and a top 63, which with a pair of wall portions 64 and 65 (Figure '1) form an enclosure 66 (Figure 8) in which a cupshaped housing 61 is rotatably disposed. Preferably walls 64 and 65 are integral with top 63 and are connected to bottom 62 as by screws 68 or the like (Figure 8) which extend through bottom 62 into walls 64 and 65. Top 63 has a recess 69 formed therein, and from this recess a boss 19 extends angularly and upwardly from enclosure 66. Boss 10 journals a stud 1 I, the outer end or which is connected to the shank of a crank 12 as by a set screw 13. The inner end of stud 1| extends into enclosure 66 and carries a coaxial bevel gear 14 which is adapted to rotate within the enclosure and within recess 69 upon rotation of crank 12.

The lower end of a stud 15 is disposed in bottom 62 and the stud extends upwardly into enclosure 66 through the bottom of cup-shaped housing 61. Bevel gear 16 is mounted to rotate in enclosure 66 about stud 15 and is in mesh with gear 14. Housing 61 has an opening 11, the edges of which fit into a groove 18 formed on the inner end of a tubular threaded element 19 similar to l The inner end of element 19 (Figure 8) carries a small bevel 80 which meshes with bevel 16 and accordingly is rotated thereby. An arm 8| extends through bevel 89 and is rotatably connected to element 19, its other end lying within enclosure 66 and being pivotally mounted on the upper end of stud 15 between aV pair of washers 82 and 83. Washers B2 and 83 and the inner end of arm 8| are held in assembled relation on the upper end of stud 15 by a screw 84 threaded into the stud.

Threaded tube 19 (Figure 6) is adapted to threadably receive a screw (not shown) similar to screw 32 (Figure 1). Upon actuation of operator 6| (Figure 6) tube 19 and its screw operate the window as hereinbefore described with respect to tube and screw 3| and 32 respectively (Figure 1). In operation of operator 6| (Figure 8) rotation of bevel 14 by crank 12.drives bevel 16 which in turn operates bevel 80. This causes element 19 not only to rotate, but also to pivot about the axis of stud 15, as the window swings in one direction or another. As elementY 19 pivots about stud 15, housing 61 turns within enclosure 66. It will now appear that the bevels in enclosure 66 comprise a differential which not only rotates element 19, but also permits swinging of this element as the window operates between the full and dotted line positions shown in Figure 6. As described above with respect to operator 2| (Figure 1) operator 6|, (Figure 6) is also adapted to be secured to a suitable base plate such as plate I5 (Figure l).

Turning now to Figures 9, 10 and 11, wherein still another form of our operator is shown, a housing 85 (Figures 9 and 11) is suitably secured as by brackets 86 to a base 81, in turn secured to base plate I5. Housing^85 and base 81 form an enclosure 88 in one corner of which (as shown in Figures 9 and 10) isrotatably disposed a bracket generally indicated at 89. Bracket includes an upper portion 9D which projects through the top of housing 85 (Figure 10) and is hollow to receive the upper end of a stud or shaft 9| to the upper end of which is connected a crank 92. The lower end of shaft 9| is rotatably mounted in base 87 and is rotatable with respect bothto the base and to bracket 89. Upper portion 90V of'- bracket 89 receives a bevel gear 93 which-isv carried by and secured to shaft 9| by a pin 94 or the like.

Bracket 89 also includes a portion 95 angularly disposed with respect to bracket portion 99' and this bracket portion 95 rotatablyv supports one end 96a of a screw 96 disposed withinenclosure 88. End 96a of the screw' which lies within bracket 89 carries a bevel 9-1 which meshes with bevel 93 so that rotation of bevel 93 imparts rotation not only tobevel 9T but also toscrew 96. v

As noted above, bracket 89 is rotatable within enclosure B8 and thus will turn about the -axis of shaft 9|. Similarly, screw 96 will swing about the same axis. f Y

An interiorly threaded nut 99 is threaded en screw 96 and, as shown in Figure 11, is constrained against rotation -about the screw Vby reason of its disposal between the bifurcations 99a and 99h of a bifurcated lever 99. Nut 98 is also pivotally related to bifurcations99a Vand 9913 by oppositely extending studs |99 'and ||l| which extend respectively into suitable holes formed in bifurcations- 99al and 99h. FromA the above, accordingly, it appears that rotation of screw 99 effects axial movement of nut 98 with respect to the screw.

Lever 99 (Figures 9 and 1l) is fulcrumed by a pin |92, which extends through the lever and through a block |93 secured to plate 89 in which it is maintained against axial displacement in any suitable manner. A friction slide shoe |95 (Figure 12) is secured to the outer end of lever 99, and slides back and forth in a track |96 secured to sash bar 29 as the window swings. Thus, movement of lever 99 operates the window.

Upon rotation of crank 92 (Figure l0) the meshing bevels 93 and 91 rotate screw 99, causing movement axially thereof of nut 98. Assuming such rotation of screw 99 as will move nut 98 downwardly, as viewed in Figure 9, this movement of the nut moves lever 99 clockwise, i. e. in a direction to close the window. However, as the nut moves toward the free end of screw 98, screw 96 is swung toward the lever fulcrurn |92 until the screw and lever reach their dotted line positions wherein the window is completely closed. Reverse rotation of the various operating parts, of course, results in opening movement of the window. Furthermore, by reason of the relationship between nut 98 and screw 96, the window is securely held not only in its open and closed positions, but also in any intermediate position, as forces exerted on the window normal to its plane are ineifective to cause rotation of screw 99.

Accordingly, it will be seen that we have provided a Casement window operator characterized by simplicity in design and efficiency in operation, in addition to its ruggedness and neat apin combination, a rhousing secured tosaid frame, said housing including a substantially horizontal base portion andl a substantially -vertical web portion lying in a plane parallel to the plane of la threaded element, means operatively connecting said Yelement to said member so as-'to rotate upon rotation of said crank,` a second threaded element threadably associated with said rst threaded element and constrained against rotation with respect thereto, whereby upon rotation of said first element by said crank said second element is moved axially o f the firstVand means for connecting said second element tothe window for operation thereof.
