WINDOW LOCKING MEANS Original Filed April 2, 1941 INVENTOR. JESSE HILL.

Patented Apr. 12, 1949 WINDOW LOCKING MEANS Jesse Hill, New York, N. Y.

Substituted for abandoned application Serial No.

1 Claim.

The present application is a substitute for abandoned application, Ser. No. 386,417, filed by applicant April 2, 1941.

The invention relates to new and useful improvements in window locking means, and it has for its object to provide a device, whereby a window may be left in a partly open position, and at the same time be securely locked.

As the construction of my device may well be said to be absolutely fool-proof, and as the said device is of a sturdy and yet simple construction, which would entail but a small manufacturing cost, it is thought that this device will be assured a great market.

With the above and other objects in view, this invention consists of the novel features of construction, combination, and arrangement of parts hereinafter fully described, claimed and illustrated in the accompanying drawings forming part of this specification, and in which similar characters of reference indicate corresponding parts in all views, and in which:

Figure 1 is a perspective view of my invention applied to a window, and with the top sash partly open.

Figure 2 shows a top plan view of my invention in a locked position.

Figure 3 is a front elevational view of my device, as shown in Figure 2.

Figure 4 is a view similar to Figure 2, showing the key member in the process of being unlocked.

Figure 5 is a top plan view, showing the key member in an unlocking operation.

Figure 6 is a perspective view of the key member proper.

Referring more particularly to the drawings, 10 indicates a window frame havin the sashes H and I2.

A plate I3, of any suitable material, and provided with a number of notches therein, as indicated by [4, is secured to one of said sashes, preferably the upper one.

Upon the other sash l2, at the top thereof, is arranged a plate member l5 secured thereto by means of screws l6; said plate member is formed with a bridge 11 upon the outer end of which a stud I8 is fixedly disposed, while upon the inner end of said bridge is arranged another stud or bolt l9.

A sliding member 20, which may appropriately be termed a key member, consists of a plate formed with a longitudinal slot 2| adapted to slidably receive therein the stud l3; said key member has another slot 22 which is open at the inner end thereof; said construction may be especially noted in Figure 6. The key member is upon the inner end thereof formed with an upward bend or end portion 23, which serves a double purpose, namely, first, that of a means for operating the sliding member 20 with respect This application April to the sash plate I3; and, secondly, that of looking the key member in a fool-proof position, when said key member after being adjusted with respect to the sash plate I3 is pulled back or inwardly, as shOWn in Figure 1. In this latter case the parts can not become unlocked before the key member 20 is pushed forward and the end portion 23 thereof passes over, or clears the stud 19, in which instance said stud 49 will become disengaged from the slot 22, thereby permitting the key member to turn upon the stud l8 and thus become disengaged from the sash plate 13.

The studs or bolts I8 and I9 are formed with heads 24 thereon in order to slidably secure the key member 20 to the plate member I5.

The end portion 23 may further, as shown in Figure 6 have the elongated slot 22 terminate in the shape of the head of the stud l9 in order to obtain a possibly still moresecure engagement of these parts when in locked position.

It is obvious that slight changes may be made in the form, construction and arrangement of the several parts, as shown, within the scope of the appended claims, without departing from the spirit of the invention, and I do not, therefore, wish to limit myself to the exact construction and arrangement shown and described herein.

What I claim as my invention, and desire to secure by Letters Patent of the United States is:

A window locking device adapted to coact with, a notched plate secured to a window sash, and comprising a plate member formed with a bridge portion and being arranged on top of a second window sash, a stud fixedly arranged upon the outer end of said bridge portion, and a stud fixedly arranged upon the inner end thereof, a key member having slots therein adapted to slidably receive said studs, heads formed on said studs and adapted to secure a permanent connection of the plate member with the key member, an upward bend formed at one end of the latter end embodying therein an elongation of one of said slots, whereby to receive one of the studs, when in locked position, said key member being turnable upon the other stud in disengaging said key member from the notched plate.

JESSE HILL.
