Specification of Letters Patent.
Patented o aia, 1909.
Application filed November 1, 1907. Serial No. 400,316.
To all whom it may concern:
Be it known that we, EDWARD D. FARMER and HERBERT B. CHURCH, both citizens of the United States, and residing at Montclair and Bloomfield, respectively, in the county ofEssex and State of New Jersey, have invented certain new and useful Improvements in Sash-Locks, of which the following is a specification.-
Our invention relates to window fasteners, and particularly to that typewhich is adapted to securely lock the upper and lower sashes of a window together.
The object of our invention is to provide an inexpensive and practically indestructible latch that combines maximum strength with minimum weight.
Heretofore it has been customary to attach cumbersome window locks to the top of the opposing rails of the respective lower and upper sashes of the window, and often to further strengthen the same, additional plates or steps have been secured to the frame of the window itself in proximity to the aforesaid locks. Such looks or fasteners, in addition to being complicated and expensive, were directly dependent upon the attaching-nails or screws, were incapable of offering greater resistance to pressure than that offered by the said retaining means and thus were subject to being readlly pried off by intruders.
We have discovered that by the provision of a draw-bolt which is received by registering recesses in the opposing rails of the two sashes, that not only is the fastening means or latch rendered entirely invisible from without, but that we are thus enabled to employ a simple and extraordinarily light construction, which, when locked, will effectually resist relative movement of the respective sashes up to the point of rupture of the sash-rails in which said draw-bolt is inserted. 1
Having thus indicated the nature and objects of our invention we will now proceed to particularly describe. the same, reference being had to the accompanying drawings forming a part of this specification.
In the drawings which serve to illustrate the preferred form of our invention, Figure l is a front elevation of a sash windowframe provided with a pair of our improved sash-fasteners, or latches, arranged on opposite sides of the window. A single centrally disposed latch is also indicated thereon, in dotted lines. Figs. 2 and 3 are transverse sectional views taken along the lines 2-2 and 33 of Fig. 1. Fig. 4 is an enlarged detail elevation of the latch in the position shown in Fig. 3 and Fig. 5 is a sectional view of the same along the line 55 of Fig. 3.
Referring to the specific latch or sashfastening means and the drawings in detail, the opposing rails a and b of the lower and upper sashes respectively, are adapted to receive a draw-bolt 1 consisting of a shank of uniform cross section intermediate its ends and a flat circular head 2 and a ball-member 3 at opposite ends of said shank.
When it is desired to lock the opposing sashes against relative movement, the drawbolt 1 is. thrust into cylindrical recesses 4 which are positioned in said opposing sashes so as to exactly register with each other when the window is closed. The bore of'the recess 4 in the upper rail ofthe lower sash is considerably enlarged at its outer end as shown at 4 and preferably a bushing 5 is inserted to further strengthen the construction; As shown, the inner diameter of the bushing corresponds to that of the recess in the opposing sash rail. It is evident that if desired a bushing may be inserted in the enlarged recess 4 and also a bushing of corresponding diameter to the bushing 5, may be inserted within the opposing recess, by slightly enlarging the said recess, to permit of the reception of said additional bushing. A circular retaining plate 6 is counter-sunk in the face of the rail (2, and is secured thereto in such a manner that the central aperture in said plate is in register with the enlarged recess 4. The said opening in the plate 6 being of smaller diameter than the bore of the recess 4, the inner beveled edge of the cap projects slightly beyond the edge of recess 4' and serves to limit the outward movement of a socket-member 7, provided with an annular flange 8 adapted to impinge against the said plate, which is thereby confined within the recess 4. The flange 8,
moreover, limits the inward movement of the socket-member and thus it is permanently confined within the recess 4', which is of sufficient depth to receive the entire socketmember.
The ball-member 3 on the inner'end of the draw-bolt is of greater cross sectional area than the shank thereof, but is of slightly less than the cross sectional area of the socket- IlieIilbel', thebore of bushing 5 and the recess 4 of the sash rail 6, all of which are preferably substantially equal. It is evident, therefore, that the ballmember 3 is adapted. to be received, by both said socketmei'nberas'well as the bushing and the recess in the sash rail 6.
The plate 6 is provided with a niche 9, and, is lightly secured to the sash rail by brads 19, which are ample to retain the said plate; orcap in position, in spite of powerful vertical pressure exerted on either sash, owing to fact that the strains are dissipated throughout the body of the respective sash rails and are not directly imparted to the aforesaid brads.
In order that the latch may present an attractive appearance, and particularly also that thesame may not interfere with screens or shades, either when locked or unlocked, the head 2 is provided. with a bevel corresponding to the opposing beveled inner edge of'the plate 6, and the socket-member 7 is provided with a circumferential slot 12 of width sufficient to receive the shank of the draw-bolt; without permitting the escape of the ball-member from the socket-member. Thus, as clearlyindicated in Figs. 2, 3. and 4, we are enabled to provide a sash-fastener with aboltwhich, when inserted within the recesses ofv the opposing sashes, is entirely invisible, even the head end merging into a counter-sunk retaining plate, whereby no projections exist. On theother hand, when the latch is unlocked, the draw-bolt, owing to the fact that it is mounted in a universal joint, readily assumes a position substantially parallelwith the sash-frame, the same being either verticalor horizontal, depending upon the presence or absence of a screw,
or other means, to support in a horizontal.
position, the shank which otherwise usually assumes a vertical position. The niche 9, as is evident, permits of the removal of the head-2 from its flush position on the plate 6, when the latch is locked. It is evident also thatthe centrally disposed latch indicatedrin dotted lines in Fig. 1 may be substitutedfor a pair of latches disposed at opposing corners of a sash, if desired, and in fact the remarkable strength possessed by latches of the type herein described, necessitates the employment ofbut asingle one of them in any case, although usually when a latch is disposed at the upper corner ofa lowersash of a window, for the sake of appearance, a companion latch is disposed at the oppo'sin'g corner. i
The latches hereindescribed are applicable in other relations in addition to windows, and "without departing from our invention as hereinclaim ed, they may be employed for locking together slidingdoors or for securing a single slidin door to its I.
frame.
Having thus described our invention, we 13131111! 1.
