PatentedAug. 3, 1915.
Application filed April 1G, 1915. Serial No. 20,466.
ATo all whom t may concern:
Be it known-that I, ROY OVERAND, a
citizen of the United States, and a resident the following a specification. A
The invention relates to devices made in two co-'acting or interlocking'parts, one of which is Xed to the-upper and the other to the lower window-sash for the purpose ot locking them when both sashes are closed.
The' principal object of the invention is to generally yimprove the construction and increase the capacity, utility and efficiency of devices of this character.
Another object is to provide co-acting memberswhich will automatically interlock when they are brought into engaging positions. f i i A' further object is toprovide a device which cannot be operated, as by a blade, hook or lother instrument, from the outside, thereby preventing a trespasser from opening the window'. 4 y
v .It ,is another object to provide a device by means of which the 'sashes will be automatically vdrawnV together as the members interlock, whereby rattling of the saslies will be prevented. Furthermore, thek sashes are brought so closely together that it will be impossible to insert even'a thin blade between them.
i That the mechanism constituting the means for carrying out the objects yabove recited be durable, strong and simple, is a prime requisite, and to provide such means constitutes another object.
Minor objectsV will presently appear; some of these will be obvious and others will be particularly pointed out.
The invention consists, substantially, in the constructions and combinations particularly pointed out,
In Ythe accompanying drawings, which illustrate a preferred embodiment of my inventionz'Figure 1 is atop plan, showing the complete invention as in use;Fig. 2, a transverse section,y partly in elevation, the plane of section being taken substantially in the line y2- in Fig. 1; Fig. 3, a perspective detail of the cam-ring'and actuating lever'fFig'. 4, an elevation of the latch-engaging member or keeper, seen in the line 4.-4, Fig. 1; Fig. `5, a bottom plan of the same member; 'YF ig. 6, a top plan detail of one of the base-plates; Fig. 7,'a front elevationof the integral latch'and spring-box; and Fig. 8, an inverted plan thereof.A
'Comingnow to a detailed description of the drawings, in which the same reference numeral uniformly indicates the same part, 2 indicatesA a base-plate having an ear 3 at each of its ends, yeach ear havingl an aperture-4.
5, 5 are bosses or supports, the former acting also as a'fulcrum or rocker for the latch and spring-box.
6 indicates a central aperture.
7 (Fig. 3) designates a combinedl camring (8) and actuating lever 9. The ring is provided with a cam-face 10, a horizontalv face 11, and shoulders '12 and 13.
- 14 (Figs. 7 and `8v) designates a latch, one
end of which constitutes a spring-box 15 provided with' a conical 'central aperture for the reception of an inverted screw 17 upon which it'both pivots' and tilts or rocks. I Thehead ofsaid screw engages the aperture'6 in the Vplate 2 andy its -threaded upper end engages thev threads of an aperture in a cap 18 provided with ears 19' having eachl an aperture 20 for the reception of 'screws 21 which passv also through the apertures 4 in the base-plate 2 andare threaded into the upper rail of the sash 22.
23, 24` indicate respectively' upper and lower panes, 'secured byv putty 25 'to the sashes. i
26 indicates the latch-stem having at its terminal a lateral projection 27 and an upstanding projection 28'. Its vextremity is preferably rounded oit' to provide a smoothcontact Iace 29, andthe inner face of the 1 projection is similarly fashionedto provide a cam-face 30, Coiled around the screw 17 is alatch-return spring 5 1 which acts both torsionally and by axial expansion. One of its ends engages'an aperture 31 in the bottom of the box` 15 and its otherend engages anaperture`32 inthe cap 18, I i
33, 33 Aindicate .Oppositely disposed arcu- 1kate grooves in the lower face ofthespringox. Y
34 indicates a base-plate each end e of which 'is apertured. e
35 lindicates a latch-receiver or keeper: having at each end an ear provided with an aperture registering with the corresponding one in the plate 34. v 36, 36 designate screws vpassedone through each pair of said apertures and threaded into the lower rail of the upper (or outer) sash, 37.
38 indicates the back, which is a plate.
39 indicates an inclined way, undercut at 40.
41 indicates a 'j projection affording a Shoulder 42, and 43 indicates a transversely arranged recessv for the reception of the latch-stem 2,6. .Y
44 represents a recess for theprojections 27 and 28. Y
TheV operation is as follows: Assume the parts to bein the relative positions shown by full lines in Fig. 1, which is the locked one. To release the interlock therlever 9 will be drawn. (against the resistance ofthe spring)- to the dotted line position m, Fig. 1, by which movement the spring-box bottom will tilt orrroclr on the boss 5 to throw the locking end of the latch-stem 26 downward, the movement thereof being caused by the cam-face 10 bearing upon said end of the lever. When the shoulder 12 strikes the stem 26 theele'ment'14 will be m0vedroflat tatively with the element 7. A further pulll with. f The operator will still hold the 'lever' and lwill simultaneously raise the sash 22 to bring the stem 26 into the inclined wayy 39 v and the projection 27 into the undercut groove 40. He will then release Vthe lever 9 and raise the sash to any position desired, the stem 26` and projection 27 sliding upward in and out of their respective channels.. Y v
To lower the vlower sash from the elevated'position just described andto klock it in the position shown in full lines in Fig. l, the lower one is merely to be drawn down, whereby the stem 26 and projection 27 will automatically enter and pass down their respective ways. When the stemhas reached a horizontal plane below that of the point 46 (Figs.f4 andk 5) the spring 51 will'auto` .matically act, by tor-sion', to throw it backward over the face ofV the projection 4l. While the above movements were progressing the bosses 5, 5 were lying inthe grooves 33 andthe bottom of the element 14 resting on the base plates. When said stem has moved entirely' past the Vshoulder 42 the beveled or inclined terminals of the'grooves 33 will move upward on the bosses 5,5 to raise the element 14 to the .full line position shown in Fig-2, the projection 28 lying locked inthe recess 44, the stem'26 against the shoulder 42, and the spring Vaxially compressed. Y i
The cam-face 30 `in moving as last described will pass behind the curved or carnface 50 ofthe shoulder 42 and thus. draw the sashes tightly together. The projection 27 will move in contact with the proximal wall of the undercut groove 40 and tend to draw said sashestoward each other as the sash 22 is being lowered.
