WINDOW LOCK.

Application filed March 9, 1923, Serial No. 624,022. VRenewed September 10, 1925.

To @ZZ/whom t may concern:

Be it known that JOS ABELLA and J MORA, subjects of the King of Spain, respectively, residing at New York, respectively, in the county of N ew York and State of New York, have invented certain new and useful Improvements in lilindow Loc-lis, of which the following is a specification.

This invention relates generally toL window fastening means, being intendedfor application to the usual type of window having vertically movable sashes, the invention having for an Object to provide a novel and simple forni of locking device for the sashes which will permit of the latter being locked in partially opened position.

For further comprehension of the invention, and of'the'objects and advantages there of, reference will be had to the following oescription and accompanying drawings and to the appended claim in which the various novel features of the invention are more particularly set forth.

Fig. 1 of the drawings is an inside face view showing the device in position on a window.

Fig. 2 is an enlarged transverse vertical section on the line 2-2 of Fig. 1.

vFigs. 3, 4l and 5 are detail perspective views of the various elements of the locking device.

Fig. 6 is a fragmentary view, of similar nature to Fig. 2, but showing a modification. l

As here embodied our improved window locking device comprises a pair of brackets one of which is mounted on the top horizontal member of the upper sash and the lower on the corresponding member of the lower sash, and a rigid rod extending between said brackets. In the drawings the upper sash is indicated at 10 and the lower sash at 11.

The bracket on the upper sash comprises a circular block 12 which lits against the face of the sash and may be secured thereto by suitable means such as the screw 13 talring through. a central aperture in the block. To hold the latter securely against rotation a key 14 may be passed through a groove 15 in the wall of the block and into the sash. Extending diametrically across the outer face of this block are horizontal and vertical grooves 16 and 17 respectively whereby the T-shaped head of the rod above referred to may be connected with the block. This 'a substantially rectangular block 25 having lugs 26 on opposite sides through which fastening screws are passed to secure it to the sash. Extending through this block from -top to bottoml is a bayonet slot 2T which opens through one side of the block.v this slot being of suliicient size to accommodate the lower end of the rod 20, which is passed therethrough. To lock the rod to the block avscrew`28 is threaded through the front wall of the latter and is adapted to engage in the selected one of a number of longitudinally spaced sockets 29 formed in the front face of the rod. .The screw 23 Amay have a suitably formed head 30 thereon for manual manipulation7 while the lower end of the rod 20 is outturned and provided with a knob 31, which ma7 be grasped when the upper sash is to be raised or lowered.

To insert the head of the rod 2O into the groove 16 in the bloclr the rod must be held in a position with its main length approximately horizontal and the bar 21 having its larger diameter alined with the groove. After the bar has reached the bottoni of the groove the rod is swung downward and its head 21 is retained against outward displacement by reason of the cross sectional formation of the bar and groove.

In Fig. 6 we have` indicated a modified arrangement of the upper end of the rod adapted to permit of more, ready insertion of the head of the rodA in the top bracket. In this construction the block 12 has a T- groove 35 therein adapted to receive the end of a T-bar 36 pivoted as at 37 in the upper end of the rod 20. Projecting from the head of this T-bar is a stud 38 which engages in an arcuate recess 39 cut into the bottom of the groove35. Slidably longitudinally in the shank of the T-bar 36 is a pin Ll() which is adapted to engage in a socket 40 in the end of the rod. This pin is urged against the top of the rod by means of an expansion spring 41 coiled around the pin socket 40, when the pin snaps into the socket and locks the T-bar to the rod, and in the same general relation to the latter that the inclined portion assumes asy in Fig. 2.

As will be understood, the ready removability and replaceability of the rod 2O is an important feature. The rod can be removed from and replaced in the lower bracket through the bayonet slot 27. With the construction shown in Figs. 1 to 5, to replace the rod in the top bracket the upper sash must be lowered, or the person replacing the rod must stand on a chair or the like, while with the device illustrated in Fig. 6 it is only necessary to pull the pin Ll0 Afrom the socket 40 by grasping the col lar l2, and then swing the T-bar to the position shown, to permit of replacing of the rod.

ll/Thile we have shown and described a preferred embodiment of our improved window lock it is to be understood that we do not limit ourselves to the precise construction herein disclosed and the right is reserved to placing the circular block l2 within the upper sash and to all changes and modifications made within the scope ot the invention, as defined in the appended claim.

Having thus described our invention what we claim as new and desire to protect by Letters Patent of the United States is as follows:

A window fastener comprising brackets adapted tor iixing on the upper and lower sashes of the window7 and a rod adapted to beremovably engaged with each of said brackets, the upper bracket having a T* groove therein, and the rod having a T- bar pivoted to its upper end and adapted to engage in said groove, said T-bar being adapted to be swung at right angles to the rod for insertion in said groove, and pin and socket elements adapted to automatically engage as the lbar swings from its said position to lock the T-bar against movement on said rod and means for locking the said rod to the lower bracket.

ln testimony whereof we have aiiixed our signatures.

JOS ABELLA. J OSE MORA.
