FASTENER FOR THE MEETING-RAILS OF SASHE'S.

SPECIFICATION forming part of Letters Patent No. 476,947, dated June 14, 1892.

Application filed November 10, 1891- Serial No. 411,428. (No model.)

T0 all whom it may concern.-

Be it known that 1, CHARLES G. LINDSKOG, a citizen of the United States, residing at Salt Lake City, in the county of Salt Lake and Territory of Utah, have invented certain Iinprovcments in Locks for the Meeting-Rails of Sashes, of which the following is a specification.

My invention relates to that class of devices which are employed to lock together the meeting-rails of sashes and the like in order to prevent the raising or opening of the same from the outside.

The object of my invent-ion is to provide a lock of this general class which shall be of neat appearance, easily applied, simple and complete in construction, and so arranged and constructed as to seriously hinder the opening of the window even from the inside of the building except by such persons as are acquainted with its operation. In addition to this my lock provides means whereby the crack or space ordinarily existing between the saslrrails is automatically and completely closed by the closing of the window whether the lock is used or not.

My invention will be hereinafter fully described, and its novel features carefully defined in the claims. i

In order that my invention may be the better understood, I have illustrated in the accompanying drawings the preferred form there of, which drawings I will now describe.

Figure 1 is a perspective view of the central portion of apair of window-sashes, showing the lock in plan, the rails being cut in cross-section, so as to show the arrangement of the Weatherstrip or device for closing the opening or space between the rails, whereby the entry of cold air, dust, &c., to the building is prevented. Figs. 2 and 3 are views of the opposite faces of the lock proper, which is adapted to be set in the top rail of the lower sash, these views being drawn to a scale somewhat larger than that of Fig. 1. Fig. 4 is a face view of the central portion of the weather-strip, showing the device for holding the same securely to the lock proper when the sashes are locked together. Fig. 5 is a view on a smallerscale, showing the position of the parts when the sashes are unlocked or the lock in its inoperative position; and Fig. (3 is a similar view showing the position of the parts when the lock is applied to hold the sashes together, and also illustrating the form of the plates or devices for the ends of the rails for bearing and automatically dropping the Weatherstrip into place as the rails meet in closing the window. Fig. 7 is a sectional view on a larger scale, showing the position of the various parts when the sashes are locked together.

In the views, A represents the lock proper as a whole, and B represents the weather strip, which in reality constitutes a part or auxiliary to said lock and serves not only as a guard to prevent the entry of cold air or dust, but to hold the two sashes firmly and securely together.

Referring toFigs. 2 and 3 especially, a is the escutcheon or plate of the lock, which is adapted to be countersunk in the top rail of the lower sash and is provided with a central opening a, through whichpass the two hinged jaws l) c of the lock proper, the outer ends I) 0, respectively, of which are somewhat hooked, in order to provide a firm hold thereon by the fingers of the operator. These jaws are hinged together at d, the jaw c being provided with a recess and jaw b with a corresponding ear b through which car and the body of the jaw 0 passes the pivot-pin d, as will be readily understood. On the end of jaw c is formed a hook 0 with a rounded up per surface, and the end of jaw 19 is correspondingly curved and hollowed out, so that when the jaws are closed, as seen in Figs. 2 and 3,an open space will be left behind the hook as seen in said views. Said jaws b and cbeing hinged together at d and the said pivot-pin being on a line with or back of the plate a, pressure on the projecting ends of said jaws will tend to open them, as seen in dotted lines in Fig. 2. A spring 6, secured to the plate a and bearing on jaw 0, serves to keep said jaw normally in place, but by its elasticity allows of the opening of the jaws under pressure. In order to insure the proper opening of the jaws, I prefer to recess the sides of the jaws slightly at c b, as seen in Figs. 2 and 3, s) as to allow of a little play; but the opening a in plate a is made the full width of the jaws, so as to admit of their being readily drawn out in releasing the sashes. Referring to Fig. 7, f is a metal pin or bolt passing through the lower rail of the upper sash and secured in position in any manner, either by riveting or by means of nuts. This pin is in position when the lock A is pushed in to take between the jaws b 0 thereof, forcing them open and compressing the spring e, and enters into the space between the jaws behind the hook 0 above referred to. Thus it will be seen that the two rails are firmly and securely locked together and will not yield to any pressure except the jaws be opened by pressure on the projecting ends thereof.

I will now describe the construction and arraugement of the Weatherstrip device, referring more particularly to the last four figures of the drawings. The meeting-rails of the respective sashes are grooved on their inner or contacting faces, and on each side of the sash, over the groove in the upper sash, is secured a plate 9, (seen in Fig. (5,) which is preferably of stout-metal plate set or countersunk in the sash. The strip B is provided at its ends with pins or studs 71, set securely therein, and these studs pass through and find hearings in the plates g, as will be readily understood, whereby said strip is held against endwise movement, but allowed to swing freely upon said studs as pivots. On the sides of the lower sash and just over the groove therein is mounted a hooked plate 11,

which is also countersunk, so as not to inter fere with the raising or lowering of the sash in its grooves, and on the ends of the strip B,

at the free sides thereof, are set other pins or studs 7, which when said strip is in its vertical position, as illustrated in Fig. 5, are in position to be engaged by the hooked end of plates 1 on either side of the top rail of the.

lower sash and thrown down into the position seen in Fig. 6, thereby entering the groovein said rail and completely closing the space between the rails, as will be understood, said strip when in the position seen in Fig. 6 touching'the floors of the grooves along its whole length. At the middle of the strip B,

where the lock A is set, is secured by screws or the like a metal plate 7c, which has at its center, as shown, a raised head or projection binding of the parts I have illustrated the. groove m provided at its end with abevel m 1 and bead Z provided with a bevel Z. On the plate a, and projecting from the lower face of the opening a is provided a pin it, which also takes into said groove in jaw b, as seen in dotted lines in Figs. 3 and 7, and which serves as a limiting-stop to prevent the lock proper A from being wholly withdrawn.

My invention, while particularly designed as a lock. for the meeting-rails of sashes, may as well be employed as a lock for other purposes, and by colorable changes may be converted into a lock for closet and sliding doors, &c.; and I do not of course wish to be understood as limiting myself to the precise construction and arrangement herein shown, as this may be varied to a considerable extent without materially departing from my invention.

Having thus described my invention, I claim 1. In a lock for the meeting-rails of sashes and the like, the combination, with the rails, one of which is provided with a pin or projection, of the hinged jaws c I), mounted in the other rail and adapted to take about said pin as they are pushed in, whereby said rails are locked together, substantially as set forth.

2. In a lock for the meeting-rails of sashes and the like, the combination, with the rails, one of which is provided with a pin or projection, of the hinged jaws c 1), adapted to take about said pin, one of said jaws having a groove m in its side, the escutcheon-plate through which said j aws play, and the pin a on said plate, arranged to take into the groove in said jaw, substantially as and for the purposes set forth.

3. In a lock for the meeting-rails of sashes and the like, the combination, with the rails, one of which is provided with a pin or projection, of the hinged jaws mounted in the other rail and adapted to take about said pin when pushed into place, and the weather-strip B, mounted in grooves in the rails and adapted to be dropped to a horizontal position when the rails come together, said jaws when in their operative position holding said weatherstrip in its horizontal position, substantially as and for the purposes set forth.

4. In a lock for the meeting-rails of sashes and the like, the combination, with the rails, one of which is provided with a pin or projection, of the hinged jaws mounted in the other rail and adapted to take about said pin, the weather-strip B, pivotally mounted to play in grooves in the rails and provided with a stud j, and the hooked plate 2 on one of the rails, arranged to take against said stud j on the weather-strip as the rails meet, whereby said strip is dropped to its horizontal position, said hinged jaws when in their operative position holding said weather-strip securely in place, as and for the purposes set forth.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
