A

Our invention is directed to a construction of sashoperator for .casement windowshaving swinging window sash;- Thesash-operatorof our invention may be fabricated-.twith and-form a part of the swinging window sash as it is delivered for installation, or the hardware of our-invention may be very readily applied to swinging window sash already in use by simply drilling a single The sash operator of .our invention is equally adaptable forboth-metaland wood window easements and frames; In showing :-the hardware of our invention applied to a Wood casement .andwood. frame, We desire that it be understood that :a similar application thereof may be made'tometal casementsand metal sash.

The hardware of our invention comprises an elongated 1 housing attachable to thewindow casement in which a longitudinally extendedscrew is disposed and which is angularly: shiftabletin position within the housing by an orientatableconnection thereof throughthe end wall of the :housingand wherein a crank is secured to an exten- 1 sion of thescrew whichprojects through the end wall of the housing; The rotatable screw engages a screw threaded-follower intricately formed with an arm which forms a; pivotal connection with the conventional arm of 1 the swinging window sash whereby operation of the crank serves to open or close thesash with respect to the case= ment. The housing for the sash operator may be con-v veniently passedthrough a mortise in the edge of theframe of the window screen, enabling the crank to be operatedfrom the interior of the casement and the window to be moved to closed or open position exteriorly of vthe sash.

We have-found the hardware of our invention very. practical and eificientvin operation, but we realize that modifications may be made, and we desire that the con-.7. structlon set forth herein be considered in the illustrative sense rather-than in the limiting sense.-

Referring to'the drawings in more detail, reference character ;1 designates the casement of the window including the easement jarnh 2 and the casement plates 3 at opposite sidesof'the casement. The casement plates.

3 includevertically ex-tending ,trackways ,4 shown more clearlyinFigs. 4 and 7and within which the sliding shoes 5 are vertically; adjustablein position. In order to 811815;;

inate lostmotion andprovide for the smooth runningofthe sliding 511,063.53 suitable'triction springs are employed which :yieldahly, maintain the connection between the Slid-r ,ing shoes 5 angl-fthe=trackways a. The sliding shoes 5 torrn=- Patented Dec. 31, 1957 pivotal connections at 6b for the sash plates 6 which project outwardly therefrom. The sash plates 6 are apertured at spaced intervals shown at Go for the attachment of sash 7 thereto,'enabling the sash to swing with respect to the casement under control of the sliding shoes to which the sash plates 6 are pivoted at 6b. The casement plates 3 also provide pivotal connections 8 for the arms 9 which are pivotally connected at the ends thereof at 6c with the sash plates 6. The arms 9 are fixedly pivoted at 8 with respect to the casement plates 3 while the sliding shoes 5 are adjustable in the trackways 4 of casement plates 3. One of the arms 9 is apertured at 9a intermediate the distance between the fixed pivot 8 and the orientatable pivot 60. The hardware of our invention is pivotally attached to the arm 9 at the aperture 9a therein by means of the screw connection 16 carried by the extension arm 11 to which the follower screw 12 is integrally attached.

The screw connection 18 is provided with a shoulder to insure an angularly movable precision joint between arm 9 and extension arm 11 that is substantially permanent in character and cannot normally be tampered with. This is accomplished by providing a recess a in the head of screw 10 that is engageable only by a special wrench which will fit the recessed socket for assembling the arms or for disassembling the arms for purposes of repair and maintenance.

The follower screw 12 projects from one side of the extension arm 11 into the path of the operating screw 14 which engages the follower screw 12 at one end and which is provided with a smooth cylindrical shank 15 at its other end. The operating screw 14 is provided with a circular flange 16 intermediate the screw threaded portion and the smooth cylindrical shank 15. The circular flange 16 serves as an abutment fulcrum for the inner end wall 17 of the housing 18 which is apertured at 19 for the passage of the smooth cylindrical shank 15. The aperture 19 in the end wall 17 of the housing is shaped in the form of two truncated cones directed toward each other and terminating in annular edged portion 19a intermediate the inner and outer faces of the end wall 17 to provide substantially a line hearing which supports the smooth cylindrical shank 15 in a position in which the screw 14 may shift angularly from a central position to a position directed toward one of the side walls 28 of the housing 18. The housing 18 is approximately U-shaped in section, closed on three sides and open on the side which is engaged against the easement 1. The side of the housing 18 which engages the casement 1 is provided with longitudinally extending

flanges

18a and 18a through which screws 21 pass for securing the housing to the casement 1. The end of the smooth cylindrical shank 15 which projects through the end of the housing 18 is provided with the rotatable crank 22 which may be revolved from a position interiorly of the casement 1 for rotating screw 14 and driving follower screw 12. To allow for the angular shifting of the extension arm 11 and follower screw 12, the housing 18 is constructed in two different transverse widths represented at 1.81; and 180. The width 18.-b comfortably accommodates the follower screw 12 which progressively moves therein to a position abutting the circular flange 16 when the sash is fully closed with respect to the casement jamb 2 as illustrated in Fig. 1. When, however, the crank 22 is revolved for rotating screw 14, the follower screw 12 is advanced to a position in which it is released from the parallel extending walls of the section 18b of the housing 18 to intermediate position where the walls of the housing diverge through the zone represented at 18d, permitting the screw 12 to be angularly displaced and thereafter provided with ample space Within which to angularly shift by reason of the broadened special relation between the side walls of the housing in the area designated at 18c. It will be observed that the inside walls of housing 18, both in the area 18b and in the area 180, are linear and parallel, interconnected by the diverging walls 18d. This facilitates the angular displacement of the follower screw 12 from the central position to the displaced position which it occupies when the window sash is moved to the open position illlustrated in Fig. 2.

When the hardware of our invention is applied to window sash of the vertically pivoted type, the operation is substantially the same as is represented in Figs. 8-14. In this arrangement the window sash is represented at 23 operating within casement 1, the window casement being provided with a sill plate 24 having a horizontal trackway 25 therein in which sliding shoe 26 moves horizontally from right to left and vice versa. The sill plate 24 is provided with a pivot 27 therein to which there is attached one end of the arm 28, the other end of which is pivotally connected at 31 to the sash plate 29. Sash plate 29 is pivotally connected at its remote end to the sliding shoe 26 as indicated at 30. The sash plates 29 at the top and bottom of the sash 23 serve to support sash 23 in a position in which the sash may be moved with respect to the side of the easement 1 in opening or closing the window. The sash operator is constructed as explained in connection with Figs. 1-7 wherein the housing 18 is attached by screws 21 to the horizontally extending casement i. The extension arm 11 of follower screw 12 connects to the pivot 32 in arm 28 intermediate the pivotal connection 27 and the pivotal connection 31.

The screen shown at 33 is readily mortised at the lower edge thereof as represented at 34 for the passage of the housing 18 as represented in Fig. 10. The operating screw 14 and the follower screw 12 angularly shift about in annular fulcrum edge 19a of aperture 19 in end wall 17 of housing 18 as the angular position of the sash is shifted as represented in Figs. 9 and 13. As heretofore explained, the difference in transverse section of the parts 181: and of housing 18 enable the follower screw and arm 11 to move through a relatively large angle as the follower screw 12 is advanced outwardly from the housing. We arrived at this construction after computing the relatively small angular displacement of arm 11 throughout one portion of the angular path of travel of sash 23 as compared to the larger angular displacement of follower screw 12 and associated arm 11 for the remainder of the angular path of travel of the window sash.

We have found the sash operator of our invention highly practical in its construction, and while we have illustrated preferred forms of our invention, we realize that modifications may be made, and we desire that it be understood that no limitations upon our invention are intended other than may be imposed by the scope of the appended claims.

What we claim as new and desire to secure by Letters Patent of the United States is as follows:

1. An operator for swinging sashes comprising a protective housing formed by a cover terminating in attachment flanges coextensive with approximately one-half the linear axis of said housing and disposed adjacent an open end of said housing, a wall closing the other end of said housing remote from the aforesaid open end, said wall being centrally apertured, a rotatable operating member disposed in said housing and having a smooth cylindrical shank extending through said apertured wall and a screw threaded shank disposed within said housing, a circular flange on said rotatable operating member intermediate said smooth cylindrical shank and said screw-threaded shank and operating as a pivot means with respect to said apertured end wall for orientation of said rotatable operating member with reference to the interior of said housing and a screw follower engaging and operated by said screwthreaded shank and orientatable in consonance with the orientation of said rotatable operating member and wh erein said protective housing has a transverse section adjacent the closing wall of the housing which is sufficient to guide the translatory movement of said screw follower and wherein the transverse section of said housing adjacent the other end thereof has its side walls more widely spaced to permit the relatively wide transverse displacement of said screw follower as the circular flange on said operating member is displaced about said apertured end wall as'a pivot.
