LOCKING DEVICE.
Application file'd'Dece'inber 29, 1925. Serial No. 73,103.
This invention relates to locking devices and has as one of itsobjects, a device'to prevent a key, on the inside of a door,-from being turned from the outside.
Another aim is to prevent-a key from being dislocated from a lock, substitution of a false key, and gaining of unlawful entrance.
These and other objects are accomplished by the novel construction and arrangements of parts hereinafter described and illustrated in the accompanying drawing and in which Figure 1 is a partial front elevational view of an escutcheon, showing the appii cation of the device in section, taken on line 11 of Figure 2.
Figure 2 is a side view of a key showing the device in normal position.
Figure 3 is a top plan view of a key, showing the device when in operative position.
Figure 4 is a. view showing the device for locking in detail.
Figure 4 shows a pin used in connection with the locking device shown in Figure Figure 5 is a view similar to Figure 2, but showing a modification thereof.
Figure 6 is a partial sectional view taken on line 11 of Figure 5. I
Figure 7 is a transverse sectional view of the modified device taken on line 77 of Figure 6.
Figure 8 is a view similar to Figure 6 showing another modification thereof.
Figure 9 is a transverse sectional view of the modified device shown in Figure 8 taken on line 99 of Figure 8.
Figure 10 is a view showing another modification of the device.
Figure 11 is a transverse sectional view taken on line 1111 of Figure 10.
Referring more in detail to the draw- 111(TZ lidably mounted on the shank of the body of the key is a band 22 having perforated lug portions 23 and 24. Loosely passing through said lug perforations is a pintle 25, having riveted ends.
Between lug portions 23 and 24 and the riveted ends of the pintle 25, and loosely engaged thereon are ears 28 and 29 forming apart of the tongue 30.
Near the end of the tongue 30 and centrally located thereon is a hole 31. Removably engaged therein and passing therethrough to an opening in the escutcheon 21 is a headed pin 83. The pin, when in operative positive position in said hole of the tongue and opening in the escutcheon pres vents the key from being turned.
The tongue '80, when in operative position, is rigidly held at right angles to the ward obviously preventing turning of the key.
Pivotally centrally mounted on the pintle 25, is a pin 32 extending in a slot 34 in the shank 20 of the key. Said pin is used to prevent the band 22 from revolving about the shank.
Figures 5, 6 and 7 show a metal strip bent around the reduced portion 41 of the shank 42, forming an eye and flat projection 70, having a perforation 48 capable of receiving a pin 44. The pin is riveted to a plate 45, which in turn is attached to a bar 46. Said bar is carried by lugs 71 and 72, riveted at both ends and located in the handle of the key. The bar is made to normally hold the plate 45 in close relation with the fiat projection 70, by action of a spring 47, coiled around said bar.
Thus, when the door is locked, the flat projection is placed at right angles to the ward 48 and partially within the keyhole 49 of Figure 1. WVhen in such position, the pin 44 is engaged in the perforation 43, holding the flat projection 70 in rigid position, preventing turning of the key.
To remove the. key from the key-hole, a. trigger 73 is pressed downward, releasing the pin 44 from the perforation 43, allowing shank 42 to revolve freely inside of the eye 40.
Figures 8 and 9 are modifications of Figures 5, 6 and 7 inasmuch as there are several pins, 50, 51 and 52. The fiat projection 53, formed by the ends of a metal strip coiled in an eye around the reduced portion 54 of the shank 55, slides on said reduced portion of the shank until the proper pin becomes engaged with the perforation 56, in accordance with the thickness of the door and the depth to which the key is inserted.
In the eye 80 is another perforation 57.
- hen the key is not used, the fiat, projec tion 53 is held in alinement with the ward 58, by causing any of the three pins 50, 51 or 52 to engage said perforation 57. Thus the key can be carried without being bulky.
Figures 10 and 11 show an L shaped piece of metal, coiled in an eye 60, around reduced portion 61 of the shank 62 to form a flat projection 63, having a loop 64- Within it, and a fiat projection 65, having a loop 66 Within it. A plunger 67 having its head 68 within the handle 69 of the key normally engages loop 64, thereby holding the flat projection 63 in alinement with ward 90.
When in operative position, said plunger I claim as new and desire to secure by Letters Patent, is
A key locking device comprising in combination with a key, a collar slidable on the shank of said key, a pin pivotall mounted on said collar, said pin being engageable in a slot in the shank, a perforated tongue pivotally mounted on said collar and means engageable with said tongue to hold the same in a rigid locked p0- sition.
In witness whereof I have affixed my signature.
