AUTOMATIC WINDOW ADJUSTER.

Application filed January 3, 1922. Serial No. 526,681.

r '1 all whom it may concern:

lie it known that I, Enwano A. \Vnrer-rr, a citizen of the United States, residing at lVichita, in the county of Sedgwick and State of Kansas, have invented certain new and useful Im n'ovements in Automatic Vindow Adjusters, of which the following a specification. v v 1 j I This invention relates to a device for maintaining sliding members, such as windowsin a predetermined position.

may be conveniently supported in any adjusted, position without the aid of counter weights, sash cords, and the ordinary sash supporting arrangement. 1 i

A further object of the invention is the provision of a;' window adjusting device of detailed description.v

the above describedcharacter, which is very simple in construction, economical to manufacture, compact in appearance, and one which may be installed at a relatively low cost. a

A further object of the invention is the provision of a sash retaining member of the above described character, which is so formed as to be adjustable to the various the same is adapted to support.

Other'objects and advantages will be apparent during the course of the following -]n the accompanying drawings, forming a part of this specification, and wherein similar reference characters designate corresponding parts throughout the several views. :Figure 1 is a fragmentary perspective view of 'a window sash member slidable within itscasing and showing the improved sash adjuster mounted therein.

Figure 2 is a rear elevation of the improvedwindow retainer. 1 F'gure i is a front elevation of the improved window retainer.

Figure 4 is a side elevation of the 11I1- proved window retainer and showing the same as applied to a sash or other support. F igure 5 is a front elevation of the improvedvsash retainer showing the same in position for supporting a sash member.

Figure 6 is a 5 front elevation of the improved sash retainer showing the same in a different arrangement from that shown in Figure 5 for the sash member.

In the accompanying drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention, the letter A, designates a window sash or other member adapted for sliding within its supporting casing B; and which includes the improved. means 0 for maintaining the same in any adjusted position which an operator may place the same.

The casing B, may of course, be any formation consistent with the use of the sliding member A. However, in the case of the ordinary window casing, the same will include a parting strip 10, and lateral retaining strips 11 and 12; said

strips

10, 11 and 12 being so positioned as to provide parallel grooves for upper and lower sash sections of a window. In order to receive the im-. proved sash retaining means C, the frame 18 of the sash A is recessed as at 14: inwardly from one side thereof, said recess having a side thereof open to directly expose a side of the parting strip 10. a

The retaining means C is of novel formation, and primarily includes the supporting element 15; roller member 16; and supporting

screws

17 and 18.

The supporting portion 15 of the in1- proved means C is preferably of some resilpurpose of supporting a ient alloymetal, such as hard drawn brass wire in order to prevent corrosion of the same. This member 15 is bent to provide a pair of arms 20v and 21, the former be ing shorter than the latter, the juncture point of said arms being looped to provide an attaching opening 22. The shorter arm 20 assumes an .acute angle with respect to the arm 21, and is provided upon its free end with an outwardly extending looped portion 23, lying in the same plane as the plane defined by the

arms

20 and 21; said loop 23 providing an elongated slot 24 which is substantially concentric with the center of the attaching opening 22, and for a purpose which will'be subsequently described. The extreme end of the looped portion 23 which lies adjacent the arm 20 is outturned from the plane defined by the looped portion 28, and provides a pointed spur 26, projecting at right angles to the plane to which said loops 23 and. the

arms

20 and 21 lie. The longer arm 21 has the lower end 27 thereof bowed outwardly, and on the extreme end providing a shaft portion 28 adapted for rotatably receiving the roller member 16 through an aperture 29 provided centrally thereof.

The roller member 16 may be any approved material and is preferably formed of hard compressed fibl,.l121.ll rubber, or the like; the same being retained upon the shaft portion 28 by the overturned split ends 29 of the arm portion 21 and which engage the outer face of the roller member 16 and prevent detachment of the same from the arm 21.

In applying the improved retainer C in the recess 11, the attaching screw 17 is so fastened into the frame as to support the leg 21 in substantially a vertical position, and whereby the roller member 16 is held in frictional engagement with a side.

surface of the parting strip 10, and substantially as illustrated in the drawings. it will, of course, be necessary to vary the force with whichthe roller 16 engages the parting strip 10 in order to support the window sash A.

Assuming the sash A to be an ordinary light window sash, the compression in the member 15 which provides the force for frictional enga ementof the roller 16 with the parting strip 10 is effected by forcing the shorter arm toward the longer arm 21, and driving the spur 2G to bite into the frame 12. The screw member 18 may then be applied through the elongated slot to prevent lateral displacement of the spin 26 iliron'i its set position. It is presumed that from time to time, it may be desired to vary the compression with which the roller 16 engages the parting strip 10. This variation of compressive force exerted by the wire member 15, is effected by releasing the securing screw 18 and until the spur 26 may be removed from engagement in the frame 13. Simply by pushing the arm 20 toward the arm 21. andt-hen secrn'ing the same in position by the securing screw 18 :nlditioi'ial compressive force will of course, be provided for forcing of the roller incinher 16 into engagen'ient witn the casing B for supporting the sash A. Two adjustments of the improved means C are shown in Figures 5 and (5, the former illustrating. a light compressive force exerted by the wire member 15, and the latter illustratiug'the relative positions of the

arms

20 and 21 when the maximum compressive force is exerted for forcing -the roller 16 into ongagement with. the parting strip 10. i

It is an important feature of the improved device G that the roller member 16 is maintained out of direct engagement with the bottom of the recess 1. 1 and whereby the same is held free to rotate as the member A is slid within the casing 13. This free suspended position of the roller 16 is insured by reason of the fact that the split end per-- tions 29 of the arm 21 directly contacts the bot-tom of the recess 14: and thus holds the roller member 16 free for rotation on the shaft portion 28.

From the foregoing, it can be seen that a window sash retaining device has been provided, which is of extreme utility, in that the same comprehends the provision of features, which render the same practical. The provision of the loop 23 having its slot 24 therein is an important feature of this invention, in that by this arrangement, together with the securing screw 18, the spur 26 may be positively held in engagement with the frame 13 in any desired position for assuring retension of the initial compression force in the Wire member 15 Easy movement of the arm 20 overthe shank of the screw element 18 is assured, without entire detachment ofsaid screwmeniber- 18, and byreason of the fact that the slot- 241 is positioned substantially concentric with. the attaching opening 22.

Various changes in the shape, size and arrangement of parts may be made to the form of the invention herein shown and described, without departing from the spirit of the invention or the scope of the claims.

I claim:

1. A sash retainer comprising a resilient wire element bentto provide a pair of arms ext-ending at acute angles to each other, said arms having an attaching loop at their juncture point, one of said arms having its free end looped to provide a slot substantially concentric with the attaching loop, and a roller element mounted forrotation upon the free end of the second arm.
