Description
Aug. 22, 1933. G. A. ARMSTRONG LOCK DEVICE Filed May 13, 1950 H MW P r 4 George. A-Armstrong IN V EN TOR. BY I a A TTORNEY Patented Aug. 22, 1933 UNETED )STATES PATENT, OFFICE LOCK DEVICE George A. Armstrong, Youngstown, Ohio I Application -May 13, 1930. Serial No.451,964
2 Claims. 70-29) This invention relates to locks.
The principal objectof this device is to provide a look so constructed that when a door has been closed from the inside, by turning the knob on the inside to open the door to go out through the door opening, the lock automatically sets a block to the outer knob of the door, preventing the opening of the door from the outside until the block has been released by a master key.
A further object of the device is to provide automatic means for turning on a light within a room by the opening and closing of the door.
A still further object is to provide means for setting the look after opening the same by'means of a master key so that the door may be opened from the outside, but will again set the block locking the door when the door has been opened from the inside by a knob of the door and closed upon going through the opening of the door.
With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and ar-- rangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the inven tion.
The invention is illustrated in the accompanying drawing, whereinz- Figure 1 is a side elevation of the device with cover plate of lock removed. a
Figure 2 is a cross section taken on line 22 of Fig. 1.
Figure 3 is a view taken on line 3-3 of Fig. 1, showing outer edge of the lock.
Figure 4 is a detail of Fig. 1. It is obvious that a lock of this nature may be adapted for many uses. It is pointed out, however, that a lock device of this type may be advantageously used in safe guarding booths such as are used for the accommodation of those utiliz- H ing safety deposit boxes in banks and the like.
One of the important advantages in the utilization of a lock of this nature in connection with a booth is provided in a lock automatically locking the door so that it cannot be opened again,
. after a person has left the booth and closed the door, until an attendant opens the door and inspects the booth, making sure that no valuables are left within the booth before allowing another person to go into the booth. This lock device provides a means of rendering an efiicient service to those using the booth in safe guarding them inside hub.
.. side.
against losses that might result if i the booth should not be inspected by an attendant before being used again.
By referring to the drawing it willb'e seen, that numeral 1 designates a casing forthe lock, and 2 a latch bolt which is provided with a springv3 to. keep it normally in a projected position. The lock is provided with a spindle hub which is in two parts, 4 indicating the outside hub and 5 the 6 indicates a pivoted lever, the free end 7 of which engages a contact arm 8 which is secured to'an inner end 9 of the latch bolt 2. This piV- oted lever 6 rests upon a pivot pin 10 and is held under tension and in a normal position by means of a spring 11. Fig. 1 shows the look from the outside with parts set so that the lock may be operated by means of anoutside door knob.
The hub 4 is formed with a slot 12 on its face engaged by an end 13 of a dogging slide 14. The slot 12 is in horizontal alignment with the end 13 of the slide member 14 when the hub 4 has rotated and indirectly caused the movement of the connecting parts-to block the lock from the out- 11- The hub 5 is provided with a connecting rod 15 which connects to an actuating pivoted lever 16 pivoted to a pivot pin 17. An end 18 of this actuating pivoted lever 16 is connected to a push rod 19. The hub 4 is provided with a push rod 20. v
In order to set the lock device after the attend- .ant has inspected the booth, he may do so by depressing an actuating slide 21. In doing this a walking beam 22 pivoted centrally on a pivot pin 23 causes the end 13 of the dogging slide 14 to be withdrawn from the slot 12. It will be noted that the walking beam 22 has each end bifurcated and functions with a pin 24 secured to the dogging slide 14 and with a pin 25 secured to the actuating slide 21. 7
It will be readily understood by referring to the drawing that either knob will operate to release the latch bolt 2 when the actuating slide 21 is depressed as shown in Fig. 1.
The action of the latch is as follows:-The position of the parts as shown in Fig. 1 indicate that the lock is in an unlatched position so that the door maybe opened either from the inside or the outside; When the door is opened from a closed position by rotating the knob 26 anticlockwise the hub 4 forces the pivoted lever 6 back, thereby withdrawing the latch bolt 2. The connecting'rod 15 moves the actuating pivoted lever 16 and comes in contact with an inner end of the actuating slide 21 thereby forcing it outwardly. As this is being done the walking beam 22 carries the dogging slide 14 inwardly seating the-end 13 in the slot 12 of the hub 4. At the same time the push rod 19 has come in contact with an electric light switch 27 and turns on a light connected to said switch. The door is now in a locked position from the outside and cannot be opened until the same has been released by the manipulation of a master key controlling secondary locking device 28. The attendant unlocks the secondary locking device 28 and revolves a cam arm 29 in a clock-wise direction so that the same comes in contact with a release arm 30 of the contact arm 8. This release arm 30 carries the latch bolt 2 into a release position. The attendant now may open the door and depress the actuating slide 21 thereby resetting the locking device.
It is obvious that when the hub 4 is rotated in an anti-clockwise direction the push rod 20 will be forced outwardly and come in contact with a switch 31 thereby turning off an electric light.
It is also obvious that the latch bolt 2 may be reversed in order to provide for swinging of door in wont to suit conditions necessary for door clearance.
What I claim is: 1. In a device of the class described, comprising a casing, a dual controlled latch bolt, inside and outside independently operable operating means including a two part hub and spindle for retracting the latch bolt, one hub part formed with a locking slot, a slide positioned so as to function with said slot for locking said one hub-part, lever means for moving said slide into said locking slot, in combination with a lock device for the purpose of retracting said latch bolt when said one hub-part is in a locked position for allowing resetting of the parts, substantially as described.
2. In a device of the class described, a casing, a latch bolt, a spindle hub in two parts, a retracting lever, a contact arm, said retracting lever functioning with said contact arm for retracting said latch bolt, one hub formed with a slot on its face, a slide bolt in alignment with said slot for locking said one hub-part and adapted to function with aid slot, one hub-part provided with a connecting rod, a pin pivoted lever, said connecting rod actuating said pin pivoted lever, a push rod connected to said pin pivoted lever, a lock device for the purpose of retracting said latch bolt when said one hub-part is in a locked position for allowing resetting of the parts substantially as described.
