CLOSURE FASTEN Application filed April 15 1922. Serial No. 555 132.

To ZZ. whom it may 007266972-1 Be it known that I, JACOB Vl nnnn, a citizen of the Republic of Germany, and resi dent of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Closure Fasteners, of which the following is specification.

One of the principal objects of this. invention is to provide a bracket adapted to be attached to window frame and window sash to hold the sash adjustably secured in plurality of inclined ventilating positions.

Another object is to provide a bracket of this character which can be quickly and easily detached from the sash to allow the sash to be freely raised and lowered in the usual manner whenever desirable.

A further object is to provide a bracket of this character with means to effectually prevent the bracket from being detached from the-sash when the sash is in any of the inclined positions and a further object is to improve upon the ar' devices with which I am familiar by simplifying the construction, whereby the devicemay be manufactured and sold at a comparatively low price. With these and such further objects in view as will be apparent to those skilled in the art to which this apperta-ins, the invention consists in the construction, combination and arrangement of parts herein specifically described and illustrated in the accompanying drawings, wherein is shown a preferred embodiment of the invention but it is to be understood that changes, variations and modifications may be resorted to which fall within the scope of the claims hereunto appended.

In th drawings forming a portion of this specification Fig.1 is a fragmentary side view of a window frame with my improved bracket attached thereto, the sash being shown in full lines in an inclined ventilating position.

Fig. 2 is a detail sid view showing the bracket in inoperative position and detached from the sash.

Fig. 3 is a front view of the parts shown in Fig.2 showing the bracket attached to the sash, and

Fig. 4 is a detail perspective showing the sash fixture attached to thesash.

Fig. 5 is a perspective detail of the sliding head, and Fig. 6 is a detail.

Referring to the drawings 10 indicates sash 12 to be constructions of simigenerally the window frame in which the upper and lower sashes 11 and 12 are mounted to slide in the slideways 13 and 14 respectively. The lower section 15of the innor retaining strip of the slideway 14 is hinged as at 16 whereby it may be swung through an arc of 180 to allow the lower moved to an inclined position as shown in full lines in Fig. 1 of the drawings. A bracket 17 is suitably secured to the frame 10 and carries at its lower end a headed pivot pin 18 which passes freely through suitable aperture in an'arm 19. The pin 18 is'preferably secured to the bracket 17 by riveting and carries between the arm 19 and the bracket 17 a pair of washers 20 between which is mounted a lock washer 21. The lock washer 21 is placed under tension when the parts are assembled, thereby holding the arm upon its pivot with a firm but yielding frictional engagement.

The arm 19 is slotted longitudin'allyintermediate its ends as at 22 to provide a guideway for the reduced end 23 of a sliding head 24 which is slotted as at 25 to provide a pair of yoke arms 24 between which the reduced end of a link 26 is pivotally secured as at 27.

Suitablemeans such as the screw 28'provided with a pair of washers 29 and the lock washer 30 are provided to hold the gagement with the arm 19.

The lower endof the link 26 is provided with a laterally extending hook 31 which is adapted to engage within the aperture 32in the lug 33 which projects upwardly from a bracket 34 secured to the upper edge of the lower sash 12. A second lug 35 suitably spaced from the lug 33 also extends upwardly from the bracket 34 and is cut away as at 36 to provide the requisite clearance to allow the hook 31 to be engaged or disengaged from the aperture 32. It will be noted that the lug is cut away so as to form an arcuate face which terminates at its upper extremity in a projecting shoulder 37 for a purpose which will hereinafter appear.

Referring to Fig. 1 of the drawing, the dotted line showing of the parts indicates the window sash 12 in closed position and from the relative positions of the brackets 17 and 34 it will be seen that the adjustable arms 19 and 26 will occupy an inclined position when engaged with said brackets. When the sash is tilted from thevertical dotted head 24 in firm but vielding' frictional encomparatively slight movement of the windew to theopen positionis-necessary to: lock the link; 26 within the. bracket.

It will thusbe seen that the window can not be opened from the outside by any unauthorized person after it has been moi'ed t anopen ventilating. position, In the assen 'bly of the parts. the lock washers are means; to. connect said link. and arm in placed under sufficient tension to hold the window. securely in any adfi sted position in which it may be placed, without necessitating any" further tightening of any. bolts, nuts or. screws Likewise due to the presence of theloch washers the parts. are held under a frictional spring tension which permitsthem tobe moiied by merely pulling the window to theg'desired position without having. to exert anfundue amount of -force.

\ It will be noted that the reduced end 23 of thehead 2d is provided with a projecting boss 4C0. which is internally threaded to. receiyeithe screw 28. The inner washer 29 and the lock washer. 30am. placed over this boss and; it. will thus be seen that the transverse or. lateral; strain produced when the head flat is. slid lalongithe arm 19 is taken up by the boss i0- and. not by the screw 28.

Having thus. described; n y invention what I claim as new and desire to secure by Let ters Patent of the United States is 1. In a closure fastener, a straight slotted arnn neans comprising a yielding frictional connection to pivotallyv secure. said arm to, a window frame, a connecting linln yielding sliding frictional engagement and detachable means to pii'otaliy connect said arm to a window sash.

2 In a closure fastener, a straight slotted arm, nieans coinprising a yielding frictional connection to pivotally secure said arm to a window trams, a connecting link, yielding means to connect said link and arm in trictional engagement, detachable means to pivotally connect said arm to a window sash and means to prevent said means from being detached from said sash when the sash is in an inclined position.

3. In a closure fastener means to secure the fastener to a window frame, a longitu dinally slotted straight arm, a head provided with a reduced end adapted to be received in the slot of said arm a threac'sed boss projecting from said reduced end. a lock washer on said boss. and means to engage said threaded boss to place said lock washer under tension whereby the head will be held in yielding frictional engagement with said arm.

at. In a closure fastener adapted to hold a window in, an inclined open position, a straight arm having a longitudinal slot therein. a head provided with a reducedend adapted to he received in said slot. a threaded boss projecting from said reduced end, a link pivotall; mounted on said head. a bracket adapted to be secured to the window sash, said-link and bracket provided with cooperating detachably engageable members, a lock washer on said boss and means to engage said threaded boss to place said lock washer under tension whereby the head will be held: in yielding frictional engagement with said arrn.

Signed at New York in the county of New York and State of New York this 17th day of November A. D. 1921.

JACOB; VVEBE
