WINDOW-LOCK.

Specification of Letters Patent.

Patented Nov. 7, 1916.

Application vfiled July 19, 1915, Serial No. 40,668. Renewed June 1, 1916. Serial No. 101,158.

To all whom t may concern c Be it known that I, HENRY Gnonem'a citizen of the United States, and a resident of Brooklyn, in the county of Kings andl closed position and thereby prevent the window from being opened, but also to draw the meeting rails of the two sashes forcibly together and thereby render the forcing of the lock, by means of atool from the outside of the structure or apartment lin which the window is built, practically impossible.

The above and other objects and advantages of my invention will appear from the following' description, taken in connection with the accompanying drawings; and be fully pointed out in the appended claims. I wish to have it understood, however,pthat the disclosure herein isillustrative only, and

vcomprises lbut one embodiment of my ini-- 'proved construction; and that the principle thereof may be practised by other constructions that are similar in effect. Otherwise stated, differences in the phrasing of they claims are intended to cover differences in structural details that I may find it advisable to adopt; provided such dierences lie within the scope and spiritvof my invention as the claims express the same.

On said drawings: Figure l is a front elevation of a portion of a pair of sashes making up a window, showing my improved lock in position. Fig. 2 is a view for the most part in section, taken on the line 2-2 of Fig. 1. Fig. 3 is a similar sectional view showing a part of the lock on an enlarged scale and illustrating more fully, the interior construction thereof; and, Fig. 4 is a perspective view of another portion of my improved lock adapted to coperate with the parts shown in Fig. 3.

. In the particular description of the drawings the same numerals of reference are used to indicate the same parts throughout `the several views. Y

I employ the numeral l to indicate the frame'of a window, and in said frame are mounted to slide in vertical guideways, arranged side by side each other, -a lower sash 2 and an upper sash 3. These sashes are arranged to be secured together by means of my improved lock, the parts of which are mounted in the lower rail of the upper sash and the top rail of the lower.; and my lock comprises a rotatable rod 4, which is carried by the sash 2 and which terminates at its inner end in a lateralarm or finger 5. This arm or finger 5 is .adapted to engage with a thimble (i, fixed in the lower rail vof the sash 3, and having'a portion 7 which provides an inclined surface which the finger 5 engages.` By causing the rod V4 to move into operative position with respect to the capl or thimble 6, the sashes 2 and 3 are secured against movement in the guides of the frame l; and by turning this rod the linger 5 engages with the portion 7, providing the inclined surface above mentioned, in such a way as to draw the meeting rails of the sashes 2 and 3 together; whereby the space` between these rails is practically closed, and the insertion of a tool between them so as to force the lock effectually prevented.

The rotatableJ rod or bar 4 is housed in a tubular casing 8, which can conveniently be made out of a piece of pipe or tubing, and is adapted to be placed in a bore or passage through the upper rail of the sash 2, made by a bit or auger. The end of thecasing 8 which is presented t0 the inside of the window. is made rigid with a perforated disk or collar 9, having openings through which screws or nails can be driven into the sash to secure the casing 8 in place. The casing and the disk are fastened tightly together, and for this purpose the adjacent end of the casing is formed over to provide a lip 10, which engages the outer face of the disk 9 snugly and closes the seam around the casing and between the same and the disk. At its opposite end the casing S receives a bearing 11, which may be a short piece of pipe or nipple of less diameter than the casing 8 and somewhat thicker, so as to provide for slidably mounting the end of the rod 4 carrying the finger 5, and thereby enable the rod to be conveniently4 reciprocated and turned when the lock is to be used.- The opposite end of the rod 4 -is surrounded by means of a bushing or sleeve 12, which may also be made of a short sec- Iii) tion of pipe or a nipple of thick tubing of such a diameter as to enable it to enter the end of the casing 8 and serve as a plunger; this bushing fitting the bore of the casing snugly, but not too tightly to prevent either reciprocating or rotatory movement. Inside the casing and surrounding the rod et is a spiral spring 18 abutting against the bearing 11 at one end and against the bushingV 12 at the other, and normally acting to urge the rod l inward with respect to the apart-- ment or building so as to keep the nger 5 in retracted ielation. The bushing 12 is, of course, made rigid with the rod 4, and on the inner end of this rod is a handle 1.1 which terminates in a finger piece 15. rlhe handle 14 may be mounted on the rod by perforating the handle and riveting the end of the rod l thereto; and if desired 1 may form a rosette on the handle ll4 around or over the riveted end of the rod 1 for purpose of ornament.

The thimble or cap G is provided with a central opening 16 in the end 17 thereof; this opening being long enough to receive the linger 5, and of less width than the length of the same. The end 17 of the cap or thimble 6 is not fiat or plane, but is provided with section 7, above mentioned, which af- A fords an inclined surface with which the finger 5 may engage, and the end of this section is joined to the remaining or plane poi'- tion of the bottom 17 by a shoulder 18. This thimble is hollow as shown partly in F ig. 2;

and the cylindrical body thereof enables it to be readily inserted in a recess 2O in the lower railkof the sash 3. This recess 2O need not be as deep as the distance between the terminal edge of the cylindrical section 19 l and the end 17 of the thimble 6; so that after inserting the thiinble 6 into the recess 20 as fai' as it will gowithout the use of tools, the thimble can` be driven in by means of a hammer or mallet until its end 17 is flush with the side of the rail of the sash 3.

The utility of my invention will now be clear. lVith the parts in proper positions the two sashes will be free to move so long as the linger 5 and the handle 111 are in the positions shown in Fig. 3; in such a case the spring 13 will withdraw the finger 5 and keep it clear of the thiinble 6 so that either sash can be opened. Then it is desired to secure the two sashes together, the bar 4 is first pushed inward, the finger at this time extending vertically downward. It is therefore free to move through the elongated openingV 16 and thus pass to the inside of the cap or thimble 6. The handle is then turned from the vertical positionshown in Fig. 3 to horizontal position or farther than this; and this rotation thro-ugh nearly half a circle will cause the finger 5 tomove loe=y against the force of the spring 13. As a result, the two sashes will not only be held against vertical movement, but drawn together horizontally so as to close the space between them. The end of the finger 5 may be beveled slightly to enable it to work more smoothly against the inclined surface provided by the section 7, and the end of the thiinble or cap G will be provided with a suitable number of holes to receive nails or fastening screws.

Y l show in Fig. 2 the adjacent faces of the meeting rails of the sashes 2 and Si Jeveled, but obviously my invention may be applied to sashes which have straight or vertical faces instead of the beveled faces, as well as to sashes which are beveled, which have illustrated. .The lock "consists of relatively few parts, and it can be readily mounted upon almost any window merely by boring holes in the sash rails of thesame diameters as the casing 8 and thimble 6 to receive these parts. After the holes in question are once made it is the work of but a moment or so to put the casing 8 and thimble 6 in place and apply the fastening devices to hold them. rllhe lock is very easy to operate and makes a very neat and compact device. Then the handle 15 is moved down to cause the finger 5 to draw the rails of the sashes 2 and 3 toward each other, all space between the two sashes is practically closed up and it becomes impossible to force the lock by means of a tool or other instrument applied between the sashes, and the window will be held in tightly closed position against any force short of that necessary to break the sash or the panes of glass carried by them.

Having described my invention, what I believe to be new, and desire to secure and protect by Letters Patent of the United States is 1.. In a lock for windows, the combination of a. short cap or thinible having one end open, said end adapted to be inserted in a recess in the sash rail, said cap having its other end closed providing a bottom having an elongated opening therein, the bottom being Hat adjacent one side of said opening and being shaped t'o have a cam surface on the otherside, the flat side of the bottom being joined to the inside by an abrupt shoulder, and means adapted to be mounted in an adjacent sash to engage the inclined portion of the bottom of said cap.

2. In a lock for windows the combination of a short cap or thiinble having one end open, said end adapted to be inserted in a recess in a sash rail, said cap having its other end closed providing a bottom with an elongated opelling therein, the bottom being fiat adjacent one side of said opening and shaped to have a cam surface on the otherrside, the flat side being joined to the inclined side by an abrupt shoulder, a tubularcasing adapted to be mounted in a bore through the rail of an adjacent sash in line with Said cap, said casing having a perforated nipple in one end adjacent the cap providing a hearing, a bar in said casing having one end projecting through said bearing, and having a finger on said end to enter said opening in the bottom of the cap to engage the cam surface7 a sleeve or bushing mounted on Said bar at its opposite end extending into the Copies of this patent may be obtained for ve cents each, by addressing the opposite end of the casing, a coiled spring 1n the casing surrounding the bar andengaging the sleeve and bearing to retract said linger, a handle secured to the bar adjacent i said bushing, a perforated disk receiving the end of the casing remote from the bearing, the said end of the casing being formed over to provide a lip to engage the face of the disk and means for securing said disk to said adjacent sash rail.

Signed at New York in the county of New York and State of New York this 14th day of June A. D.- 1915.
