HENRY G. VOIGHT, OF NEW BRITAIN, CONNECTICUT.
WINDOW-LOCK.
Specification of Letters Patent.
Application led February 23, 1912. Serial No. 679,309.
To all whom t may concern.'
Be it known that l, HENRY G. VOIGHT, a citizen of the United States, residing at New Britain, Hartford county, State of Connecticut, have invented certain new and useful improvements in llVindow-Locks, of which the following is a full, clear, and exact description.
rlhis invention relates to means for locking together the adjacent rails of window sashes, and in its broad aspect comprises, in combination with a pair of relatively movable sashes, a latch member carried by one of the sashes, a detent carried by the other ofthese sashes and adapted for locking engagement with the latch member, and means for retracting the detent from locking engagement and for eecting relative movement of the sashes.
The invention in its preferable embodiment is illustrated in the accompanying drawings in which- Figure 1 is a vertical sectional view showing the invention applied to window sashes of the astral type. Fig. 2 is a plan view of the parts in locking engagement, the parts of the window sashes being omitted. Fig. 8 is a similar view` of the parts with the locking detent retracted. Fig. 4 is a vertical section through the parts on the line 4-4, Fig. 2. Fig. 5 is an enlarged detail view of the base carrying the spring-pressed detent. Fig. 6 is an enlarged detail view of the latch member and its attaching plate. Fig. 7 is an enlarged detail view of the detent member detached. Fig. 8 is a detail view, on an enlarged scale, of the actuating lever.
Referring to the drawings by numerals, 1 indicates a window casing' in which are mounted window sashes 2-3 provided with roller shades 4 adjacent to their tops and pivoted. intermediate their ends at 5. A double armed lever 6 connects these sashes so that when the top of the lower sash is pulled inwardly, a corresponding motion is imparted to the upper sash, the sashes assuming, when fully opened, a parallel position at an inclination of about 45, as illustrated in dotted lines in Fig.- 1 of the drawings. The roller shades or curtains 4 attached to the two sashes, when drawn across the sashes when the latter are tilted as described, form in eifect an awning. This type of window sash arrangement is known as the astral type, and while my lock is particularly adapted to such a type of window, it is, of course, susceptible of application to other forms of window.
The locking means proper consists of a plate 8 adapted to be mounted upon the lower rail of the upper sash and provided with a hooked latch member 9 projecting outwardly therefrom. The plate proper is provided with a pulley 10 mounted adjacent to the inner end of the latch member and having thereunder a rope or cable aperture 11. This pulley and its aperture is designed to coperate with a pulley 7 secured to the top of the upper sash 2 to carrj7 a cord for railing' and lowering the shade of the upper sas Cooperating with the plate 8 and its latch member 9, and suitably positioned relatively thereto upon the top rail of the lower sash, is a base member 12 suitably secured to this top rail and provided at one end with a housing 13 and at the other end with a raised bed plate 14, a channeled portion 15 being formed therebetween into which the latch member 9 of the opposite sash is adapted to project. Sliding within the housing 13 is a detent shaped to engage with and hold the latch member 9, said detent comprising a head 16 having a beveled front edge 1Ga corresponding to the beveled face of the latch member 9 and a straight rear edge 1Gb, and having a rearwardly projecting shank 17, the detent head 16 being normally projected out through a recess 18 formed in the housing, and the shank 17 extending through an aperture 19 in the opposite face thereof. The detent head is normally projected from the housing by a coil spring if() mounted upon the shank 17 and within the housing 13, and a guide plate 21 is located within the housing and coperates with the edge of the detent as it is projected from and-retracted in the housing. Extending from the upper edge of the detent head 1G is a flange Q2 which, when the detent is projected outwardly by the spring, extends across and above the channel 15 to a point adjacent to the edge of the bed plate 14.
1t will be obvious from the structure so far described that when the sashes are swung closed, the latch member 9 will be projected into the channel 15 of the base 12 and under the iiange 22 of the detent, its rounded end 9EL striking against the beveled face of the detent 16 and forcing it inwardly until the straight edge 9b of the latch recess Patented Oct. 22,1912.,
clears the end of said detent, whereupon the spring will snap said detent into engagement with the latch recess and prevent relative movement between the sashes until the detent is withdrawn from such engagement by the means which l will now describe.
In order to retract the detent from locking engagement with the latch member, I provide an actuating lever 24 pivotally mounted upon the bed plate 14 by means of a pin 23. This lever has its outer face adjacent to its pivotal point recessed at 25 to form abutment surfaces 26 which engage with a pin or stud 27 mounted in the bed plate in the arc of movement of the abutment menibers and limit the amount of movement of the actuating lever 24. The inner edge of t-his lever adjacent to the flange 22 of the detent is provided with an angular eXtension forming in effect a cam face 28 adapted to coperate with the flange 22 to retract the detent from locking engagement with the latch member 9. The free end of the actuating lever is formed with an eye 29 designed to be engaged by a hook or other hand implement to retract the detent and tilt the window sashes in the manner to be described. The latch carrying plate S and the bed plate and housing on the base 12 are each provided with suitable means for securing the same to their respective window sashes, one such means being the countersunk apertures 30 adapted to receive a screw or other suitable securing means.
The operation of the lock is as follows: Assuming that the window sashes are closed and that the spring-pressed detent is in locking engagement with the latch member, as shown in full lines in Fig. 1 of the drawings; the operator, by means of a hook or other suitable implement, engages the eye 29 of the actuating lever 24 and turns the same inwardly from the position shown in Fig. 2 to that shown in Fig. 3, the extension 28 of this lever engaging with the flange 22 of t-he detent and pressing the detent head 16 within the housing 13, thereby freeing the latch member 9. Further retracting movement of the lever is prevented by the engagement of the abutment surface 26 with the pin 23. A continued pull on the actuating lever will tilt the window sashes, which can be thus moved to the desired inclination by one continued pull on the actuating lever, which first releases the locking detent and then tilts the window sashes. When the sashes have been tilted to the desired degree of inclination, the actuating lever may be released, whereupon the coil spring 2O will project the detent 16 outwardly, its flange 22 striking against the cam face of the lever and returning it to the initial position shown in Fig. 2. `When it is desired to close the window, the hook is inserted in the eye in the actuating lever and a straight push will bring the sashes back to their original closed position, the pressure on the actuating lever being taken by the pin 27. The detent being independent of the actuating lever, it follows that when the latch member 9 contacts with it, the detent will be forced back in the housing 13 until the sashes have resumed their normal position, whereupon the detent 16 will snap into the recessed portion of the latch 9 and again lock the upper and lower sashes firmly together.
It will be noted that the lock, as illustrated, is designed to afford the least obstruction possible to the roller shades and these, therefore, when unrolled, will eXt-e-nd entirely across the glass of t-he sash.
While l have illustrated a preferable embodiment of my invention, it is susceptible of various structural changes and adaptations within the spirit of the invention and of the appended claims. My lock may, for instance, be used with a stationary and a swinging sash and is susceptible of even wider application, for by adaptation it can be used in connection with sashes or other closures in which one of the members moves, swingingly or otherwise, toward and from the other. By the term relatively movable sashes, I do not, therefore, limit myself to the use of a pair of sashes or even one swinging sash, but mean, broadly, two sashes or analogous structures, one of which moves relatively to the other.
lVhat I claim, therefore, and desire to secure by Letters Patent is:
