' INVENTOR q? A TTORNEYS WITN ES BENJAMIN LEICHTER, OF BROOKLYN, NEW YORK.
' WINDOW on KEY LOCK.
Specification of Letters Patent.
Patented Oct. 11, 1921.
Application filed June 25, 1920. Serial No. 391,644.
To all whom it may concern Be it known that I, BENJAMIN LEICHTER, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn in the county of Kings and State of New York, have invented a new and Improved Window or Key Lock, of which the following is a full, clear, and exact description.
This invention relates to builders hardware and has particular reference to looking or safety devices for window catches, locking keys or other movable parts or devices.
Among the objects of the invention is to provide a safety device for cooperation with a locking member or catch, which safety device when in adjusted position will serve to prevent or materially reduce the likelihood of the catch or the like being moved or released to permit the opening of the window, door, or the like, by any unauthorized person.
A further object of the invention is to provide a safety device of the nature indicated that will be simple and cheap in construction and easy to apply in practice, as well as being eflieient andrreliable for the purposes intended.
With the foregoing and other objects in view the invention consists in the arrangement and combination of parts hereinafter described and claimed, and while the invention is not restricted to the exact details of construction disclosed or suggested herein, still for the purpose of illustrating a practical embodiment thereof reference is had to the accompanying drawings, in which like reference characters designate the same parts in the several views, and in which- Figure 1 is an inside elevation of a window showing my improvement in position to prevent the release of a conventional form of lock or catch.
Fig. 2 is a plan view of the device on a larger scale.
Fig. 3 is a plan view of a modified arrangement indicating the adaptability of use of the device in many different positions.
Fig. 4 is an inside elevation of a fragment of a door and its lock, the safety appliance being shown in position to prevent the turning of the key by the use of a pair of pliers or the like from the outside of the building.
Referring now more specifically to the drawings 1' show in the first set of figures my improved catch or look as comprising a forked member 10 connected permanently and movably with respect to a relatively stationary member or base 11 adapted to be secured by any convenient means such as screws to any convenient part of the window frame, door, or other device with which my improvement may be associated. The means for connecting the forked member to the base is shown aS comprising a hinge joint 12, the axis of which is transverse to the axis of the notch or crotch 13 formed in the movable member.
In Figs. 1 and 2 I show a conventional form of window lock comprising a cam shaped catch 14c pivoted at 15 for movement around a vertical axis on the top of the lower sash 16 and adapted for cooperation with a stationary catch 17 fixed to the lower part of the upper sash 18. The catch 14 has a finger piece 19 for manipulation thereof and this finger piece in the locked position of the lock lies ordinarily to the left and substantially parallel to the upper rail of the lower sash l6.
As one of the various means for employing my locking device in practice I show the base 11 fixed to the upper rail of the lower sash 16 with the pivot 12 at right angles thereto and with the forked member 10 so located as to straddle or embrace the finger piece 19 when the window lock is in looking position.
The forked member 10 comprises two fingers 20 and 21, the former a little longer preferably than the latter and having an upturned end for convenience in the manipulation thereof. When the window lock is being manipulated the member 10 is swung upward and to the left around the axis 12 out of the way. After the window lock is adjusted to locking position the forked member 10 is swung downward to the position shown, the finger piece 19 being received in the notch or crotch 13 thereof and is so held by the finger 20 from accidental or surreptitious unlocking movement, especially from the outside of the building. By making the finger 21 shorter than the other the forked member is freer to swing into and out of cooperative engagement with the window catch.
In Fig. 8 I indicate how the improved device may be connected to a window or the like in other positions than as set forth in Figs. 1 and 2. In Fig. 3 the base is secured to a block 22 fixed to the front i ace'of the window sash'16.
In Fig. 4 I show the adaptability of this device to a door, the base 11 being fixed to the door just below the knob 23 and with the forked member 10 in position to embrace the door lock key 2 so as to prevent the rotation of the key and the unlocking of the door by a tool applied through the door look from the outside.
I claim: A locking device for a window or door lock, comprising a base havlng means whereby it may be secured in position adjacent to the member to be locked, and a member hinged to the base and having a pair of spaced fingers at one end, one of said fingers relatively short and flat and the other'-KZO of said fingers relatively long and having its free end bent outwardly, said fingers adapted to receive and hold a movable part between them, the shorter finger permitting a movement of the part to be locked, the longer finger preventing movement of said part in one direction, and said outwardly bent portion of the longer finger serving as a fingerhold to permit manipulation of'the hinged member. 7
