GASEMENT-WINDOW OPERATOR.

Application filed June 28, 1926. Serial NO. 119,174.

The present invention relates to improvements in window operating devices, and more particularly to devices for the operating of casement windows.

The primary object of the invention is to provide a casement window operator whereby the window sash may be operated from the inside of the building without the necessity of raising or removing of a screen supported by the window casing inwardly of the sash.

A further object of the invention is to provide a novel type of casement sash operators which may be operated for swinging of the sash without the necessity of reaching out of the window when desiring to swing the sash to a closed position in the window frame.

A still further object of the invention is to provide a device of this character which is extremely simple and durable in construction, which may be n'ianufactured at a relatively low cost from stock rods of asuitable gauge, and which devices are of such construction as to permit of the sash being locked in a closed, opened, or intermediate position.

Other objects and advantages of the inven tion will be apparent during the course of the following detailed description, taken in connection with the accompanying drawings forming a part of this specification and in which drawings:

Figure 1 is a transverse section through a casement window construction and showing the improved device applied thereto for operating of the casement sash.

' Figure 2 is a transverse sectional view similar to Figure 1 but showing the operator in a locked position for retaining the easement sash in a closed position'in the window frame.

Figure 3 is an enlarged detail sectional view on line 3-3 of Figure 1 and looking in the direction of the arrows.

Figure 4 is an enlarged vertical section on line ie-40f Figure 2, looking in the direction of the arrows and portion of the easement window construction.

Figure 5 is an enlarged fragn'ientary section on line 55 of Figure 1, and showing the construction of portion through which the operator extends.

Figure 6 is an enlarged fragmentarysection on line 66 of Figure-2 and illustrating the locking arrangement for the operating device.

Figure 7 is an enlarged fragmentary section on line 7 --7 of Figure 2.

showing merely the lower the window screen at that Figure 8'is an enlarged fragmentary perspective view of the hinge connection between the operating device and the easement sash.

Referring to the drawings in detail, and wherein similar reference characters designate corresponding parts throughout the several views, A designates a window casement or frame provided with thecasement sash B, C a window screen closing the window opening inwardly of the casement sash B; and D the improved casement sash operator for swinging of the sash B to an open or closed position with respect to the frame A.

Referring to the window frame or casing A, and which is of usual construction, the same comprises a sill 10, stiles 11, and the usual stop beads 12 carried by the confronting faces of the stiles 11 intermediate the longitudinal edges of the stiles and which beads form stops for the easement sash B.

The casement sash B for closing of the opening of the frame A, embodies the lower rail 14 and the side rails 15, the sash being of that type which is hung upon one vertical side to one of the stiles 11 as by means of suitable hinges 16 having one wing secured to the stile and its opposite wing'secured to one of the side rails15 of the sash. With this type of casement window construction, and as will be observed in Figure 2, when the sash is moved to a closed position, the'same abuts against the stiles 11 for limiting inward swinging of the sash. I

The constructon of the window as shown, is commonly known in the art as an outwardly opening casement window.

The screen C, and which may either be of the sliding or hinge type, in the example shown embodies a bottom rail 17 resting upon the upper surface of the sill 10, and side rails 18 abutting against the inner edges of the stop beads 12. The screen C in casement windows of this type must necessarily be dis posed inwardly of the easement sash in order to permit of the sash being swung outwardly to an open positioinand as will'be observed in Figure 2 when the sash is swung to a closed position, a space the width of the beads 12 is provided between the sash and screen, and in which space the major portions of the operat ing means D come to rest when the easement sash is swung to a closed position by the operating means.

Referring now to the easement sash operator D, the same embodies anoperating lever 20 in the form of a bell crank, providing a throw arm 21 and a relatively short ofiset operating arm 22. The operating lever 20 is formed from a flat bar of metal of a suitable gauge, and is pivotally mounted'at 'its'apex as by means ofa suitable pivot pin 23 to the upper surface of the sill 10. 'l hispivo't pin or fulcrum 23 may be in the form of a headed screw turned into the sill at a point relatively close to the outer side of the screen C and in the space formed between the'sash B and the screen. Formed at the outer end of'the throw arm 21, as by means ot'bending up an edge portion of the arm, is-a stop 24. The ofiset operating arm 22 extends'inwardly through an elongated recess 25 provided in the bottom ed 'e oi the'botto'n'rrail 17 of the screen to a position whereby the same may be readily grasped for swinging of the lever 20 about its fulcrum, pin 23 from a position inwardly of the building. The inner end of the arm-22'may be provided with asuitable operating linob'26. A yie'ldable flap27 may be secured to the outer side of the bottom rail 17 above the recess-'and extend downwardly over the recess in a manner for closing of'the recess and yet permitting of ime movement 01: the arm'22 along the recess. As will be observed in Figures 5 and 7, the relatively flat-operating lever 20 lies flat upon'the upper face otthe sill 10. 'Pivotally connected adjacent the outer end of the throw arm 21, and upon the'upper'side olthe arm, as by a suitable pivot pin 28, is a link 30 having a recess 31 provided in one longitudinal edge thereof and into which the stop 24 of the throw a'rinmoves :Whenthe armand link are in substantial alignment as illustrated in Figure 1. The outer end of the linkSO is pivotally connected asby means of a suitable L-sh'ap'ed bracket 35 'to the lower rail 14: of the sash B at a point substantially midway between the siderails ThisL-shaped bracket 35, and "as will be observed'in Figure 4, is secured to the inner face of the lower rail 14 at a point spaced slightly upwardfroin the lower edge of the rail for allo'wing'the bracket to clear the stop 36 01 the sill 10 whenthe sash is swungto'a-closed position.

Securedatone end to the operating arm 22, and preferablyadjacent the knob '26, and means of a suiItable'ri-vet or the like .39, is an areu'ate shaped locking plate 40 extending in an arc concentric to the pivot pin 23. This locking plate or arm 40, adjacent its connection with'th'e operating arm 22,'is provided with an upwardly oflset portion 41 which overlies the arm '22, and provides a shoulder 42 adapted to engage one edge of the arm for rigidly retaining the locking plate against swinging movement about'its securing pin 39. The locking plate 40 is provided with a series ofapertures 44 which are adapted to receive a locking pin l5carried by 'the sill 1O 'and'projecting upwardly from the upper face of the sill in a path of the arcuate movement o f the arcuate sh'aped locking'plate. This arcuate shaped perforated locking plate 40 and co-acting lockingipiir mserve-as means for adjustably locking the easement sash B in various ang g'ular relations with respect to the window frame A, nd in the dotted line showing in Figure "1,th'e centrally disposed aperture of the locking plate is shown engaged by the pin 45 for retainingthe sash in a partially opened locked position. The olls'e'tjprovided in the attaching end of'the'locking pl'ate 430 disposes the major portion of the plate which provided with the apertures 44, in surface contactupon the upper face of the sill 10 and it can be seen that upon grasping ot the 'lin'ob 26 that the Operating arm 22 may be sprung upwardly for withdrawal of the locking plate lroin'the pin 45}when desiringto adjust-or op'erate'th'e sash 'B.

WVhen the sash B is swungto a rull 'opened position, the arm 21 and 1ink 30wi1lbelocked by means of the stop 24am recess 31, i'nya position for retaining the sash in an opened position, and in 'which position "the locking plate 40 need not'necessarily engage the lo'cking pin 45. When the sash is in "a fully closed position as in Figure2,the aperture nearest to the operating arm 22 will'receive the locking pin 45. lVhen 'desiring to "open the sash from a fully closed position as in Figure 2, 'the' operator first grasps the! knob 26 and upon a slight upward;pullin *disengages the arcuate 'loc'kingjplate '40 from the locking pin 45, an'd whichfreeing'dfi the arm 22 will allow the OperatingleVerQO 'tobe swung about its fulcrum 23"for swinging of the sash B about its hinges 16. v I i The recess 25 provided in the loweredgeof thescreen C, isofa lengthto allow the free end of the locking plate 40 to {pass beneath the screen when the operator is'in "a position for retaining the easement sash in a "closed position, and as will be observedin Figure 2 a very small portion ofthe operating d'evice extends inwardly past the screen C'when the sash is in a closedposition. I c

From the foregoing description'it willbe apparentthat an extremely simple yet elficient type of casement sash operators h'as been provided whereby the sasheso'f casementwindows provided with screens disposed inwardly of the sasln'may be readilyoperated'without raising of the screen, and embodying featines-whereby the sash m-ay be locked in either an open, closed, or intermediate positions.

Changes in detail may be made "to "the specific form of the invention "herein shown and described, without departing from "the spirit ofthe-inventio'n or the'sco'pe ofth'e' fol lowing claims.

I claim: I
