1 Claim. l This invention relates to window latches, and more particularly to the provision of a window latch for holding a window sash in definite predetermined positions.

rlfhe usual window which comprises an upper` sash and a lower sash movable relative to each other is generally provided with a latch for holding the window in a completely closed position. There are many instances when it is desired to have the lower sash slightly raised or cracked for Ventilating purposes, and at the same time prevent the entrance of burglars or the like, or to prevent children from falling out of the window.

It is, therefore, an object to provide a latching device which can be attached to the upper sash and the lower sash to hold a lower sash in a definite raised position. While devices have been heretofore provided in windows for holding a lower sash in a definite raised position to prevent surreptitious entrance of persons, such devices have usually been built into the window and are not in the nature of attachments.

It is a further object to providea latching attachment to hold a lower sash in several different raised positions, the device being arranged so that it can be released only from the inside of the window. There are countless windows which have no latching means, and the latching device herein presented provides means which can be readily attached by means of a few screws.

A further object is to provide a window latching device of simple structure, making it easy to manufacture and inexpensive, and enabling it to be sold at a low cost so that it will be available to all classes of persons.

These and other objects are attained by the novel construction and arrangement of parts hereinafter described and illustrated by the accompanying drawings, forming a part hereof, and in which:

Fig. 1 is a perspective view showing the device applied to a window sash.

Fig. 2 is a side view showing an element of the device applied to the upper sash of the window.

Fig. 3 is a front view of the structure shown in Fig. 2.

Fig. 4 is a front view of a detent forming a part of the device.

Fig. 5 is a sectional view taken on the line 5-5 of Fig. 4.

Fig. 6 is a sectional view taken on the line 6-6 of Fig. 5.

Referring to the drawing the window latching device is shown to comprise an angle 3, prefer- 2 ably made of stainless steel or similar substantial metal, the angle 3 being attached to the bevel side 8 of the sash by means of screws 1 passing through the enlarged portion 6, which portions are integral with the longitudinal portion 5. This allows a space between the sash I and the portion 5. On the portion indicated by 3, which is at right angles to the portion 5 there is provided a plurality of openings or slots 4, and due to the bevel part of the sash I room is provided on the inside of the portion 3 to allow a plunger to pass through the slots 4. In the event the sash has no bevel part 8, washers are placed beneath the portion 5 to give the proper spacing for the passage of a plunger. v

On the upper horizontal cross piece 2l) of the lower sash 2 is mounted by means of screws passing through horizontal anges I2, a casing having an upper wall 9 and side walls II, the flanges I2 being integral with the side walls II.

Integral with the upper wall S is a front wall Ill having an aperture through which passes a plunger I5 adapted to enter the slots 4. Fixed to the cross piece 28 is an angle having a vertical side I3 and a horizontal side I4, the latter being attached to the cross piece by means of screws or the like. A plunger passes through the vertical side I3 and has a head I6 which engages fork I'I of a handle I8, which is provided with. a bowed portion IIJ to give leverage to move the plunger backward against the action of the coiled spring 22 which abuts a disc 2l fixed to the plunger I5 and the side I3. In operation, to release the window the handle I8 is moved to the right (see Fig. 1) to move the plunger to the right as would be the case as shown in Fig. 6. The window can now be moved to various positions as may be desired and the plunger allowed to enter any of the slots at the desired position. In this manner a window can be positively latched from the inside thereof to provide various openings from. the bottom of the window to prevent the entrance of burglars or children falling out of the window, and at the same time enable the passage of air for Ventilating purposes.

It is obvious that the device can be applied to almost any window, many of which are equipped only with means for latching a window in a completely closed position.

The device is simple and comprises, obviously, few parts which can be quickly attached to the sashes by means of a few screws. The device is inexpensive to manufacture and can be sold at a very low cost so that it can be available to persons of all means.

It is made of stainless steel, brass or ordinary steel or any strong metal.

The above description is to be considered as illustrative and not limitative of the invention of which modifications can be made without departing from the spirit and scope of the appended claim.

The invention having been described, what is claimed is:

In a latching device, a first xed plate having an aperture therein, a Vsecond fixed plate having an aperture in alinement with and spaced from the aperture in the rst plate, a plunger passing through said apertures, a disc on the plungeradjacent the rst plate, a coiled spring encircling the plunger and positioned between ltheadiscgand the second plate, a head on the plunger ,adjacent the second plate, a forked plate positioned "between the head and the second plate, said plunger passing between the forks of the forked plate, said forked plate having a portion bent back substantially parallel to the forked portion and then further bent to provide a portion substantially at right angles to the forked portion.
