1 Claim. 1:

The present inventionrelatesto improvements in adjustable holders or supports for window sashes and other closures, by means of which the closure member may be-yieldably supported and held in closed or angular open position relative-to awindowor door-frame;

The device which constitutes this invention is particularly suited for use in connection with window sashes of metal or other material having a swingable connection at one end. or the other to the window frame, and embodies a friction joint soconstructed and arranged as not only to produce friction betweentwo surfaces suificient to holdthesash at a predetermined position under ordinary conditions; but includes protuberanc'es onsaidsurfaces that normally will maintain the position of adjustment of the sash until pressure greater than normally encountered in use is exerted tochange the adjusted position of the sash.

The frictionparts of our adi'uster are spring pressed and subjectto adjustment to increase or decrease the frictional contact as may be desired.

The objects and advantages of the invention will appear more clearlyfrom the following detailed description whentaken in connection with the accompanying, drawing showing preferred embodiments of our inventive idea.

In the drawing:-

Figure l is a front elevationv oi our invention as applied to a. window sash and. frame, and in a position assumed when the sash is in closed position;

Figure. 2' is a. view in side elevation showing in dotted. linesthe position. oi'the parts=when the sash is in. partially opened. position;

Figure 3 is an enlarged sectional view taken about on the line 33 of Figure 1, looking in the direction of the arrows, showing a supporting bracket and the radial projections thereof;

Figure 4 is a section like Figure 3, on the line 4-4 of Figure 1, looking inthe direction of the arrows, and showing the lower end of a supporting bar with radial projections about its pivot;

Figures 5 and 6 are fragmentary views of the pivot end of a supporting bar and cooperating bracket, respectively, with a modified type of projection or holding means on the surfaces thereof; and

Figure 7 is an enlarged sectional View on the line 11 of Figure 1, showing more particularly the slide connection between the supporting bar and the sash closure.

Like reference characters designate correspending parts in theseveral figures of-thedrawmg.

specifically describing the invention, designates a window frame, and 2 the closure or window sash, inthis instance, pivotally connected at its top-to the frame so as to swing outwardly from closed. position toangular open position, as shown in dotted lines in Figure 2. It is: to be understood that this closure member may be a storm sash or other type of closure, and that the adjuster device constituting this invention may be applied to one side or duplicated and applied to both sides thereof. It is suflicient, however, to describe one of-these adjustable holding devices.

Such. an adjuster support comprises essentially a. bracket3, the; base of. which is secured. by'the screws 4'to theaface of: the window frame adjacent tothe opening. Extending from said base at right angles thereto is an: ear- 5 having. a central bolt opening 6. therethrough. Surrounding"v this opening the; metal is: stamped to: provide a. circle of radial projections or; ribs. 1,. the function of which will be more? particularly pointed out: as this description proceeds. Cooperating with this bracket is a supporting, bar 8 which at its lower end, as. shown in. Figure; 4- ofthe; drawing, is also provided with a bolt-receiving;opening 9, and likewise formed: with a: series of radial ribs I O for cooperation with the ribs 1: of the. bracket 3 to provide a more. or less: positive holdin-gl; action for the supporting bar; The said barisv connected to the bracket car by means of a bolt orpivot H on which is mounted a washer [-2, and a tens-inning spiral spring I3; the tension of which. is designed to be regulated by the nuts it, one 0t which constitutes a locking nut: to prevent unscrewing of the: nuts: afterv they; have beenv adjustedv to provide the necessary tension. This adjusting means. is design-edto produce the desired amount of friction between the coacting surfaces of the bracket ear 5 and the,- lower end of. the supporting: army 8:. It should be; understood that, the ribs I and. lillon these parts are arranged face to face so that as the arm is moved relative to the supporting bracket, the ribs ride over each other and arrange themselves so that each rib of the arm will lie between a pair of corresponding ribs formed on the bracket ear, and due to the amount of tension exerted by the spring I3, the movement of one rib over the other requires the exertion of a relatively great amount of pressure upon the sash.

It will be noted in Figure 2 of the drawing that the bar 8 is formed with an elongated slot I5 3 closed at its ends. This bar extends vertically when the window sash is closed and is adjustably connected to said sash by means of the bolt l6 which extends through an ear I1 formed on the bracket I! attached to the sash frame, as by means of the screws l8. The bolt I6 is reduced in diameter at its free end so as to provide a shoulder I 9 against which is seated a washer 20,

as clearly shown in Figures 1 and 7 of the drawing. Mounted upon the reduced and threaded end of the bolt I6 is a second washer 2| between which and the first washer 20 the lower end of the supporting bar or arm 8 is mounted. The bolt l6 also carries a tensioning spring of spiral form designated 22, and the tension for this spring is obtained by the adjusting and locking nuts 23. Suflicient pressure is provided for this connecting means to provide for friction on the inner surfaces of the washers 20 and 2| and the supporting arm 8, so that this friction added to the friction produced by the connection of the arm to the bracket 3 will hold the window sash at any desired angular position, such as shown in Figure 2 of the drawing, and by means of the radial ribs 1 and on the bracket 3 and lower end of the bar 8, said sash will be more or less positively held at any one of the adjusted positions of said sash with relation to the window frame.

' The tension on the parts above referred to, however, is not intended, normally speaking, to be so great as to prevent the adjustment of the sash at any time it is desired to adjust the window sash to control the area of the opening, but

it will be obvious that in the event it is so desired to hold the sash at a predetermined angular position, the nuts I 4 and 23 may be adjusted to increase the pressure to the point where the coacting ribs 1 and II] will positively hold said sash at the adjusted position. It is preferable, however, in the use of this device that only a sufiicient amount of friction of the parts will be provided that the sash may be manually adjusted to any angular position with a reasonable amount of exertion on the part of the operator.

Instead of employing the ribs 1 and II] as described above, we contemplate employing a series of circular or semi-circular protuberances in both the supporting arm 8 and bracket 3, as shown in Figures and 6 of the drawing, respectively. In this arrangement, the semi-spherical projections 24 are intended to normally seat in depressions or indents 25 formed in the bracket so that, when it is desired to adjust the window sash, the latter is pressed outwardly to thereby cause the projections 24 to ride out of the recesses 25 onto the intermediate surfaces of the parts and to then snap back into the recesses when the proper opening of the sash is reached. In this manner, the sash is more or less positively held at the adjusted position controlled by the amount of tension which is applied to the connecting bolt l I.

It will be understood that projections of different shapes than those which are illustrated in the drawing may be formed in the coacting parts, and, therefore, we do not wish to be restricted to the precise shape which has hereinbefore been described with reference to the radial ribs 'I--l0 and protubrances 24-25. By the construction of the adjuster support as set forth herein a simple method of holding a closure member in open or closed position is provided, and the adjustment of the friction or camming surfaces is easily accomplished to overcome wear or to increase and decrease the extent of friction of the sliding connection between the sash and the slotted bar 8, as well as the connection between said bar and the frame bracket 3.

Other changes in configuration and size of the parts may be made without departing from the spirit of the invention and within the scope of the claim hereto appended.

What we claim is:

An adjuster device for vertically swinging window sashes or the like comprising a supporting bracket having an oifstanding ear, a supporting arm projecting upwardly and connected at one end thereto by a connecting bolt passing through said arm and bracket ear, radially arranged semispherical projections projecting from the contiguous faces of said arm and bracket ear, a spring carried by said connecting bolt, adjusting means on said bolt for producing more or less friction between the arm and bracket ear to resist free movement of the arm, said supporting arm having an elongated slot therein, and sash connecting means comprising a bracket secured to the face of the sash and projecting therefrom to the plane of the slot, a bolt projecting from the outer end of the sash bracket and having a shoulder adjacent the inner face of the arm and extending through said slot and slidable in said slot when the arm is shifted on the bracket connecting bolt, spaced washers between which the arm is disposed, a spring on said shouldered bolt, and an adjusting nut urging said spring and washers toward said bolt shoulder to provide more or less friction between the arm and washers.
