SAS H-FASTEN ER.
SPECIFICATION formingpart of Letters Patent No. 631,964, dated August 29, 189.9. Application filed November 30,1898. Serial No. 697,376. (No model.)
To all whom it may concern.-
Be it known that LGE RGE R. MoOnEsNEY, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented new and useful Improvements in Sa'sh-Fasteners,of which the following is a specification.
Myinvention relates to an improvement in sash-fasteners.
It is an object of my invention to provide an improved sash-lock which shall operate to lock the upper and lower sashes in any required adjusted positions and which may be readily manipulated to unlock the same, said lock operating simultaneously on both sashes to lock or unlock them.
My invention has for a further object the provision of improved mechanism for operating the lock, which mechanism may be set to hold the lock in a locked or unlocked position.
The above are the general objects of the invention. Further objects of the invention relate to certain details of construction and operation of the parts, all of which will more clearly hereinafter appear.
In the accompanying drawings, illustrating the invention, Figure 1 is a sectional elevation. Fig. 2 is a horizontal section. Fig. 3 is a sectional elevation taken at right angles to Fig. 1. Fig. 4 is a perspective view of the lock and the operating mechanism therefor. Fig. 5 is an inside view of the lock, and Fig. 6 is a sectional detail view of the operating mechanism.
The reference- numerals 1 and 2 indicate, respectively, the upper and lower windowsashes, and 3 indicates the window sash frame. Secured along the inside face of one of the outer rails of sash 1 and extending from top to bottom thereof is what I term a locking-strip 4, which lies flush with the surface of the rail and is provided at equal intervals with a series of oblong apertures 5. A similar strip 6 is provided along the outside face of the corresponding rail of the lower sash. Secured in the frame 3 at a height corresponding to that at which the horizontal rails of the window-sashes meet is the locking mechanism, the casing of which is indicated by the numeral 7. Said casing is made from a single piece of metal having its edges turned inward at right angles to its body portion to afford flanges inclosing the mechanism in the ordinary manner and is secured in any preferred manner within the frame to lie. flush with the surface thereof.
The main locking member comprises a lever-arm 8, having at one end upper and lower integral extensions 9 10, forming what I term a locking-arm, and at said end being loosely mounted on a stud 11, secured to the casing 7 and being adapted to slide on said stud, as hereinafter described. Secured on the end of the stud 11 within the casing is a leafspring 12, which bears at opposite ends on the extensions 9 10 toward the ends thereof, as shown. Said extensions 9 10 have on opposite sides integral portions 13 14, respectively, bent at right angles to said extensions and projectingthrough suitably-shaped openings 15 16, formed in the face of the casing. The upper projecting portion 18 has on its upper side an integral portion 17, bent at right angles to itself and curved downwardly, forming what I will term a bearing-flange, which projects a considerable distance from the face of the casing and bears against the edge of the upper window-sash, as shown and for a purpose presently described. The casing 7 issnitably cut out to receive said bearing-flange17, as shown. The end of the proj ecting portio'n'l3i'salso bent outward at right angles to saidprojecting portion and in the same direction as the bearing-flange 17 to forma locking-hook 18, which also is curved slightly downward, as shown, and is adapted to engage in the apertures 5 of locking-strip 4. The lower projecting portion 14 has a corresponding bearing-flange 19 and lockinghook 20, these parts being curved upwardly and extending in an opposite direction to the upper bearing-flange and hook and being designedtoengage, respectively, with the lower sash and locking-strip 6 in the same manner as the like parts just described. The hooks 18 and 20 being located, respectively, on op-. posite sides of an integral swinging arm formed by the extensions 9 and 10 will be moved simultaneously in opposite directions when the lever-arm 8 is raised or lowered, as will be understood.
Mounted on a stud 21 is a coiled spring 22, having one end bearing against a flange 23 of the casing and its other end suitably bent and provided with a friction-roller 24, bearing upward against the under side of the lever-arm 8. The spring 22 tends to hold the lever-arm 8 in a raised position, and thus keepsthe locking- hooks 18 and 20 in engagement with the apertures of their respective locking-strips.
The free end of lever-arm 8 is provided with a series of apertures 25, in any one of which, for the purpose of adjustment, may be secured the upper end of the rod '26 for operating said lever-arm.
Those portions of the casing 7 which are cut away to provide the openings 15 16, respectively, are turned outward at right angles to said casing on opposite sides of a vertical line, in such manner that they may engage opposite sides of the parting-strip 27, in which they may be seated to lie flush with the respective faces thereof, said bent portions being indicated, respectively, by the numerals 28 and 29. The sides of the parting-strip respectively opposite the bent portions 28 and 29 are cut out to form recesses 30 and 31 to permit movement of the locking-hooks.
The rod 26 extends downward through an opening 32 in flange 23 and is connected to the operating mechanism, which will now be described.
The frame 3 is suitably recessed to receive a hollow cylindrical housing 33, provided at its inner end with a circular flange 34, having apertures therein whereby the housing may be secured by screws or the like to the win-' dow-frame. The cylindrical housing is provided with two longitudinal slots 35 36, respectively, connected toward their outer ends by a cross-slot 37. Extending through the housing 33 and revolubly seated therein is a plunger 38, having secured therein a pin 39, which is adapted to work in the slots 35, 36, and 37. Encircling the plunger 38 is a coiled spring 40, which bears at one end against the end of the housing and at its other against a shoulder 41, formed on the plunger. The spring 40 tends to press the plunger 38 outward or toward the operator. Said plunger, as stated, extends through the housing, its
outer end having a milled turned button 42 of any preferred kind and its inner portion without the housing being continued as .a squared extension 43, which projects some distance within the frame. On this squared portion is secured by means of a set-screw 44 a crank-arm 45, which may be adjusted longitudinally on said plunger and secured by said set-screw. Said crank-arm is of the curved shape shown and is bifurcated and provided with a series of transverse apertures 46, adapted to receive a pin by means of which one end of a link 47 maybe secured in the bifurcation of the crank-arm. Said link is provided at each end with a series of perforations 48 49, respectively, the series 49 being intended for the pin securing said link in the crank-arm 'and the series 48 being intended for the lower end of rod 26. By means of these perforations in the crank arm and link the correct adjustment may be obtained relative to the length of the rod 26 to insure that a throw of the crank-arm shall lock or unlock the sashes, as the case may be. It will be understood without further specification that recesses, such as shown at 50 and 51, will be provided in the frame and of such dimensions and so located as to permit the proper working of the parts described. The parts are normally in the locked position shown.
The operation is as follows: When it is desired to unlock the sashes, the plunger 38 is pushed inward against the resistance of spring 40, which brings the pin 39 opposite the slot 37. The turn-button 42 is now turned downward, which brings pin 39 opposite slot 36, when the spring 40 will throw the plunger outward, the pin 39 entering slot 36. As the plunger 38 is turned downward the crankarm 45 is turned with it, and this movement, through the medium of link 47 and rod 26, pulls the lever-arm 8 downward against the resistance of its spring 22, whereby the locking- hooks 18 and 20 will be drawn out of the apertures of the respective lockingstrips,and the parts will be held in this position by means of the engagement of pin 39 in slot 36.
22 raising the lever-arm 8 upward, and thereby,thro'ugh the medium of rod 26, drawing the crank-arm 45 upward and spring 40 pressing the plunger 38 outward, bringing pin 39 again in slot 35.
It has herein been stated that the lever-arm 8 was slidably mounted on stud 11 and movable thereon against the resistance of leafspring 12 and that the edges of the sashes bore against the respective bearing- flanges 17 and 19, which are integral with said leverarm 8. The purpose of this construction is to provide a yieldingcontact for the sashes whereby to offset any swelling or'shrinkage of the latter, the construction'described insuring that the said bearing-flanges will always remain in contact with the sashes, the leverarm 8 moving on the stud 11 against or in obedience to the force of the spring 12, ac cording as the sashes swell or shrink. By this movement of the lever-arm the lockinghooks will always be in position to engage in the apertures of the locking-strips.
