OASEMENT-WINDOW FITTING.

Application filed December 13, 1922. Serial No. 606,712.

To all whom it may concern:

Be it known that I, 'THoMAs MCCREA FULTON,

21 -Morang Road, Hawthorn, in the State of Victoria, Commonwealth of Australia,

have invented new and useful Improvements which the the inside of the window and which screenv is suitably supported on a wooden batten.

secured to the lower" sash framing and restin on the window sill. 7

his window batten or screen support is suitably recessed and holed to receive the window lever or guide rod and. a slidable plate carrying same and which permits of the movement of the lever without interfering with the screen, which feature. is not possible in the present construction of casement window fittings.

The window lever or guide rod em loyed herein is pivotally jointed to a stoc and comprises two concentrically disposed tubular members, both of which have a number of equidistant holes, in their adjacent sides. The inner tube is adpated to be revolved within the outer one and is provided with a number oflockin slots which lead from the holes therein and adapted to be engaged by an inwardly projecting locking tongue which latter forms part of a cover plate secured to the inner face ofthe screen supporting batten.

In order to securely lock the lever when the position of the window has been adjusted the lever is drawn towards the locking tongue and when the holes in both tubes, are in a position the inner tube is turned downwards and towards the tongue whenthe slots in the inner tube are engaged by the said a British subject, residing at No.

'holes (l formed in tongue and securely held or jambed therein. 511 By turning the locking tube in the opposite irection the slots therein are freed or disengaged from the tongue permitting the window to be again adjusted as is desired.

The invention will now be described hav- 65 ing reference to the accompanying drawings, in which- Fig. 1 is a plan, and

Fig. 2 is a vertical sectional elevation of a casement window and fittings assembled to ether according to this invention.

ig. 3 is an elevation of a cover plate which is slotted to receive the window lever or guide rod.

Fig. 4 is a part sectional plan ofFig. 3.

Fig. 5 is an enlarged fragmentary part of Fig. 3 showing the window lever or guide rod locked by a locking tongue.

Fig. 6 is a part sectional elevation of the window lever or guide rod, and

Fig. 7 is a detail of Fig. 6.

In constructing the improved window fittings I'employ a transverse wooden batten A of a suitable height and thickness which is supported on the window sill F and is suitably screwed or secured to the sash frame The inner surface of the said batten- A is recessed as at A and provided with a central opening A for the reception of a slidable plateand lever respectively.

The front of the recess A is closed by a cover plate B which is suitably screwed to the batten A the recess being adapted to house a slidable plate C, the latter being centrally holed at C to receive the window lever or guide rod. The said lever or guide rod comprises two concentrically disposed tubes D and D and an arm D which is flexibly connected or jointed at d to the outer tube D. A number of equidistant holes cl is formed in the'side of the tube D and which are in apposition and adapted to register with a corresponding number of the inner tube D the said holes (1 having extended slots or grooves d formed in the circumference of the tube D The cover plate B is provided with a slot ill b, one'of the side edges of which is formed with an inwardly projecting locking tongue or member 6 which is adapted to be engaged by a set of holes dlafter the position of the casement window has been suitably adjusted, the inner tube D being turned to bring one of the narrow slots or extensions d into engagement with the tongue 6 the said groove gripping or securely holding the latter which is formed with a slight outward curve, thus securely holding and locking the guide rod or lever. The inner tube D is provided with a knurled head or knob (Z in order that it may be conveniently turned and the window locked or unlocked, as the case may be.

The head (1" is also provided with a solid neck 03 which is secured to the inner tube While the outer tube D is provided with a semi-circular slot 03 for engagement with a set screw 03 which slot and screw permit and limit the oscillatory or turning movement of the inner tube D When the Window is being opened or closed and the window lever or guide rod is being thrust forward or backward the slidable Plate C is, reciprocated laterally in the recess A and acts as a guidefor the said window lever or guide rod. When the desired adjustment of the window has been made it is only necessary to draw the lever DD towards the locking tongue and engage the latter with the holes d and d respectively, thus securely locking the window. The improved construction of window fittings herein enable a fly-proof screen to be used in conjunction with a casement window the screen H'being positioned on the inside of the window and resting on top of the batten A and which arrangement enables a screen to be effectively used with a casement window without interfering with the movement of the guide rod or lever or of the window itself as would occur with the fittings-at present in use.

Havingnow described my invention what I claim as new and desire to secure by Letters Patent is 1. Improvements in casement window fittings comprising, in combination, a vertically mounted screen support having a recess and an opening therein and secured to the sash framing, a slotted cover plate secured to said screen support and positioned over the recess in said support, a locking tongue formed with said plate, a vertically mounted slidable plate formed with a'hole therethrough housed in the recess of said screen support, a window lever pivotally connected to a stockand carried by said slidable plate, and means for locking said lever to and disengaging the same from said locking tongue.

2 In casement window fittings, in combination, a screen supporthaving an inner recess therein, a cover platepositioned over the recess of said screen support, locking means on said cover plate, a slidable plate formed with a hole therethrough housed and working in the recess of said support, a win dow lever working in the slidable plate and comprising concentrically arranged tubular members, a window stock pivotally connected to the said tubular members, means for engaging said tubular members with said locking means on saidcover plate and for disengaging said members from the said locking means.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
