Our invention relates to electrically operated locking and unlocking means for doors or windows of a dwelling or building and for any and all purposes for which it may be employed, and
is especially designed for simultaneously looking and unlocking both the upper and lower sash of a window, although either or both sashes of the window may be closed without operating Y. the lock electrically.
The prime object of the invention is to provide simple, durable, economical and thoroughly eiilcient electrically operated means disposed within the casing of the doors or windows so as to lock or unlock said means'by making the proper contact from any safe and convenient point, such as the opposite side of the room from said doors or windows, by any authorized person desiring to lock or unlock the doors or a windows.
A further object of the invention is to provide means so associated with both the upper and the lower sash of a window that, after either sash shall have been lowered or raised for ventilation purposes, both sashes may be simultaneously locked in their adjusted position by making the proper contact by means of a push button or any suitable switch.
Another object of the invention is to so construct the latch bolt with relation to means secured to the edge of each window sash that,
when the sashes shall have been adjusted to any desired position and locked in such position, it will be impossible for any person seek- Y ing unauthorized entrance through the window by the raising of the lower sash, or the lowering of the upper sash, but both sashes may be en-- tirely closed without operating any means electrically.
Further objects of the invention are to so construct our improved locking and unlocking means that such means may be disposed within a suitable metallic casing, and connected by suitable wires to the lighting circuit of a building and to form a part of the regular wiring of the building, the said locking and unlocking means may be successfully operated by merely pushing a button suitably located at any convenient point, and to associate said means with a lighting circuit adapted to operate a pilot light to indicate when the door or window is locked or unlocked.
The foregoing and such other objects as may appear from the ensuing description are accomplished by the combination, arrangement, construction and location of the several parts hereinafter more fully described and particularly pointed out in the claims appended hereto, and illustrated in the accompanying drawings, it being understood that slight changes in the precise form, proportions and minor details of the construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.
In the accompanying drawings forming a part of this specification it will be seen that:
Figure l is a plan partly in section illustrating the means embodying our invention, showing said means in its unlocked position.
Figure 2 is a detail partly in plan and partly in sectional elevation, showing the latch bolt in engagement with a window sash.
Figure 3 is an elevation partly in section, showing the locking means in looking engagement with the sashes of a window, showing said sashes in their partly lowered and raised positions, and
Figure 4 is a cross section taken in the plane of the dotted lines 4-4, Fig. 1, showing in section a portion of the window sashes broken away.
In the embodiment of our invention as illustrated, it will be seen that the numeral 1 designates a metallic casing suitably disposed within the casing of a door or window, said casing being provided with vertically disposed partitions 2 and 2' and laterally disposed partitions 3 and 3' extending from the partition 2 to the inner side wall 4 of said casing, the partitions and side walls being formed from a single piece of metal. Suitably secured within the casing and between the partitions 2 and 2' are two electromagnets 5 and 6, one adapted to force the latch bolts into their locked position and the other to withdraw the latch bolts into their unlocked position through the medium of the means hereinafter described.
Disposed intermediate of the two electro-magnets is a member 3 formed of a single piece of metal formed with a large central portion 9 adapted to slidably engage the inner face of each of the partitions 2 and 2 and formed throughsaid central portion 9 is a diagonally arranged slot 10 terminating with a slightly upwardly curved formation at one end thereof, and at its other end with a slightly curved downward formation, said curved formations serving to lock and maintain the latch bolts in their unlocked and locked positions, respectively, and formed within said central portion 9 is a cavity or recess for the reception of the latch bolt operating member 12, said member extending inion wardly and provided with a lateral extension 13 at each side of its headed portion 14 and terminating with a narrowed inwardly extended portion 15 adapted to suitably separate the locking and unlocking latch bolts 16 and to engage the headed portion 14' thereof, while through the upper end of the headed portion 14 of the operating member 12 is suitably secured a pin 17 which projects from each side of said headed portion and is adapted to engage with the slot 10, and formed integral with each end of the central portion 9 is a plunger 18 which forms the movable cores for the electro-magnets 5 and 6. Connected to an opening formed through the partition 2 and an opening through the outer wall of the casing 1 is a sleeve 19 in the outer end of which is fitted a screw threaded plug member 20 and at its inner end portion is disposed a metallic ball 21 with a coiled spring 21 disposed between the plug member and said ball, said ball being adapted to be seated in a semicircular recess formed near each end portion of the member 8, shown by dotted lines, and serving to secure said member at each end of its movement, and thereby prevent accidental movement of said member 8 in either direction,
- locking and unlocking latch bolts 16, as is clearly electrical source, said wires being suitably conthe locking magnet 5, thus causing the member as shown in Fig. 1.
It will be perceived that a coiled spring 22 is disposed between the extensions 13' and the upper end or headed portion 14 of each of the shown in Figs. 2 and 4.
It will be observed that an opening is formed through the metallic casing through which are passed the wires 24 and 25 connected with the nected with the locking electro-magnet 5 and the unlocking magnet 6, so that when it is desired to look a door or window it is simply necessary to push one of the buttons 27 which will energize 8 and its cores to move or slide downwardly, thereby causing the latch operating member to force the latch bolts 16 into their locked position, which will be readily understood, and when it is desired to unlock the latch bolts press the other push button electrically connected with the unlocking magnet, thereby causing the member 8 to move in the opposite direction to withdraw the latch bolts.
When it is desired to use a pilot light in connection with our electrical locking and unlocking means, a light circuit is used through the wires 28 and 29leading to an incandescent lamp 30, and to the electrical contact 31, formed by placing an insulation plug 32 at the end of one of the magnet plungers to which plug is secured a metallic member 33 adapted to close the circuit through the contact 31 and light the lamp to indicate that the doors or windows are in locked condition, as shown in Figs. 1 and 3.
It will be understood that our improved looking and unlocking means may be employed for all purposes for which it may be utilized, in connection with or without any light indicating means.
By reference to Fig. 3 of the drawings it will be seen that the window frame 34 is broken away to show the casing 1 containing the locking and unlocking mechanism suitably disposed within said frame, and showing one of the window sashes 35 in a lowered position and the other sash in a raised position, while the latch bolts 16 are shown in their locked position with relation to the said sashes, with the push buttons arranged adjacent the window frame and the indicating electric light disposed above the window frame.
