J. A LANE WINDOW STAY Filed Dec. 6, 192( Patented Nov. 6, 1923.
winnow STAY.
Application filed December 6, 1920. Serial No. 428,473.
To all whom it may concern:
Be it known that I, JAMEs A. LANE, a citizen of the United States, and a re'sidentof the city of Los Angeles, county of Los Angeles, and State of California, have invented a new and useful Improvement in Window Stays, of which the following is a specification.
This invention relates principally to props or stays for holding swinging windows in open or partly open position.
The principal object of the present inven-' tion isa simple efficient stay of neat appearance which can be readily applied to various designs of windows, doors, blinds or other swinging members for holding said members in open or partly open position. Another object is to cheapen the cOSt'Of manufacturing such stays and to provide means whereby the parts of the stay may be adjusted to take up wear and to varythe frictional resistance of said parts and thereby make it greater or'less according to the size and weight ofthe window to which the stay is applied.
The invention consists principally in' a window stay comprising links pivotally secured together and adapted for pivotal connection with the window-sill and windowsash respectively, and in the means for creat: ing sutlicient stiiiness or frictional resistance in one or more of the pivotal joints to hold the sash in adjusted position. The invention further consists in the improved manner of taking up wear between the friction elements. The invention further consists in the means for varying the frictional resistance between said elements whereby the stay can be adjusted for use with windows of different weights and sizes. The invention further consists in the parts and arrangements of parts hereinafter described and claimed.
In the accompanying drawing, which forms part of this specification, and wherein like symbols refer to like parts wherever they occur, r
Fig. 1 is a horizontal section taken through the hinged side of a casement window with the sash closed, showing a window stay embodying my invention applied thereto, the sash being shown in partly open position by the dot and dash lines; 7
Fig. 2 is an inside view of the lower por-' tion of the window, showing the stay in side elevation;
Fig. 3 is an enlarged vertical section ta ken through the anchor member on the line I r Fig. 4c is a horizontalsection taken through the anchor member onthe line 4'-4 in Fig. 3; I
Fig. 5 is a vertical section taken through the anchor member on the line 5-5 in Fig. 3; i I Fig. 6 is asection similar to Fig. 5 taken through a modified form of anchor member,
and l Fig. 7 is a similar section taken through another modified form of anchor member.
In the accompanying drawings, my invention is illustrated as applied to a casement window. which comprises a frame 8, a window-sill 9, and a sash 10 pivotallyfmounted at one side of the frame 8 by means of hinges 11 so as to swing outward.
The stay comprises horizontally disposed long and short links 12'and-13 pivotally se-i curedtogether; The endof the long link 12 is pivotally attached .to'the sill 9 inside of of the sash jlO bv means of an anchor plate 14, and theend ofthe short link is pivotally secured to the bottom rail of the sashlO by means of abracket 15. p I
The inner link 12 and the outer link 13 are arranged to swing in a horizontal plane, the link 12 being disposed. substantially parallel with'the rear face of the sash 10 and the link 13 extending rearwardly at an angle I from the outer end of the link 12 toward the anchor plate Min the closed position of said sash. The outer link 13 ispreferably. at-
tached to the sashlO between the outer end ofthe inner link 12 and the pivot bracket 15. Thus, the outer end of the outer link 13 swings in an arc described from the sash hingeill, and the inner 'endofsaid link,
frictionalresistance created in one .or more of the pivotal joints resists swinging movementof the pivotal links 12 and 13 and causes said links to function as a prop or I stay for holding adjusted position.
The swinging movement of the link 12. is resisted principallyby the frictional contact betwen thei parts which constitute'the pivot support for its inner end. These parts the window initlie desired are preferably housed within a cylindrical cap 16, which fits over an upstanding circular boss 17 formed in the anchor plate 14 and has a slot in its side .wall through which "Located within the upper portion of the cap 16 is a circular friction plate 20 having oppositely disposed arcuate flanges 21, which project upward therefrom on opposite sides of the link 12, whereby said friction plate is forced to rotate with the cap16 when the link 12' is swung. Located within the cap 16. be
tween the upper surface of the upstanding circular boss 17 of the anchor plate leand the lower surface of the friction plate 20, is a friction disk or washer 22. Located beneath the upstanding boss 17 of the plate 14 is another friction disk or washer 23.
Extending downwardly through the cap 16 is an adjusting screw 24, which prevents endwise withdrawal of the link from the cap. 'The screw 24: also serves as a means for clamping the parts of the pivot member together and as a means for varying the pressure of the frictional contact between the friction members. The screw 2 1 is threaded into a pivot screw or block 25 of rectangular section. This pivot block is disposed centrally within the cap 16 and extends through a' central openng' in the fric tion plate 20. This opening is of a size and shape corresponding tov the cross sectional shape of the pivot block 25 so as to rotate with the friction plate 20 when the link 12 is swung. wardly through alined central circular open; ings in the friction disks 2 and 23 and in the boss 17 of the anchor plate 14, which openings are of a diameter suiiicient to per rnit the pivot block to turn freelytherein.
'A circular ,clamping plate 26 is secured'on the reduced lower end of the pivot block 25, whose lower end is upset to retainsaid plate in position thereon. The plate26 supports the lower friction disk and holds the upper surface thereof in contact with the under surface of the circular boss 17 of the anchor member 13. The head of the screw bears on a washer 27 which rests on or housing 16.
A friction washer 28 is arranged between the pivotally connected ends'of the links 12 and 13. and a rivet 29 is preferably used for pivotally securing said ends together. A friction washer 3O is also arranged between the horizontal flange of the sash bracket 15- and the adjacent outer end of the link 13.
The outer end of the link 13 is pivotally secured to the horizontal leg of the sash bracket 15'by means of a"rivet 31.' The vertical leg of the sash bracket is secured to the in The pivot block 25 extends down ner face of the bottom rail of the sash 10 by means of wood screws 32. The friction washers 22 and 23 and the washers 28 and are made of copper, aluminium or any other soft metal having a tendency to increase of the frictional contact between the V movable parts of the stay.
Vith the ement described, the
tightening of the adjusting screw 24 causes the soft metal washer 22 to be clamped tightly between the under surface of the friction plate 20 and the upper surface of the upstanding boss 17 of the stationary an chor'member 13. This action also causes the washer 23 to be clamped between the un der'surface of the boss 17 and the upper surface of the clamping plate 26 on the lower end of the pivot block 25, the pressure of the frictional contact between the soft metal friction washers and the parts on opposite.
made'greater or less, according to the size and weights of the sash, and also permits said friction elements to be adjusted to take up wear. e
In the modified form of construction shown in Fig. 6, the lower edge of the cylindrical cap 16 is notched to straddle the lugs of the anchor plate 1% so as to prevent rotation of said cap. The cap is also provided with an arcuate slot 32 adapted to receive the inner end of the link 12, which slot is of a size sufficient to enable the said link to be swung 90 degrees. The friction plate 20 is provided with a central circular opening throu gh which projects a pivot screw 33. A friction washer 22 of copper or other soft metal is disposed between the under surface of the plate 20 and the upper surface of the upstanding boss 17 of the anchor plate 146. The pivot screw passes through alined circular openings in the cap 16. link 12. plate 20 and washer 22 and is threaded into the anchor plate 14 ll ith this arrangement. the action of tightening the screw 33 clamps the washer 22 between the anchor plate 14 and the plate 20. thus increasing the frictional resistance between the friction elements and retarding the swinging movement of the link 12.
In the modified form of construction shown in Fig.7, the cap 16 is secured directly to the window-sill, thus rendering the use of a separate anchor plate unneo essary. The cap is slotted horizontally, as at 32 to receive the inner end of the link 12, said slot being of a length which will permit the link to be swung degrecs. The friction plate shown in Fig. 7, except for its inverted position, is identical with the plate 20-. A friction washer similar to the friction washer 22 is arranged between the upper surface of the plate 20 and the under surface of the cap 16". A vpivot screw, which is similar to the screw 33, extends downwardly through alined circular openings in the friction washer, plate and link, and has anut 34 on its lower end. The purpose of this nut is to increase the frictional resistance between the friction elements and also to take up wear.
The hereinbefore described arrangement admits of considerable modification without departing from the invention; therefore, I do not wish to be limited to the exact details of construction shown and described.
