"My invention relates'to improvelnents in locks, especially locks having bolts "for holding doors or the like, in closedposition.
An-object of theyinvention'is to :provide 6--a lock comprising parts to :be-adjus'tedto enable the bolt-to be retractedeither with a key, or without a -key, by the'turni'ng of a-knob; with the bolt adapted" to be moved to full projected position andsecurelyheld so that it cannot be withdrawn-except :by
2 Figure 1. t
The same numerals identity the same parts throughout.
At 1 is indicated a casing closed at the back and on all four sides, but open in front to enable it to belaid against a dooron the side or surface which is turned to the inside of the enclosure or room to which it 2 leads. In this casing is 'aslidable bolt 2, projecting through an aperture 3, and having a slot 4, to receive a square guiding stud 5 in the casing. A spring 6 abuts at one end against this stud, extends through an open bore in the inner end of the bolt, and rests at its opposite end against the far side of the casing; and a pin 7 in the bolt connects the bolt and spring, engaging the spring at a point such that the spring normally acts to project this bolt not quite its full distance through the aperture 3.
The bolt has rack teeth 8 on its lower edge to mesh with circular teeth 9 on a shaft 10, carrying a knob 11, and being hollow to receive the stem or another knob on the outside face of the door in the usual way. On the upper edge o'fthe bolt is a lateral extension 12, forming a shoulder '13, and having a recess 14. At 15 is a lever 01' latch pivoted upon a pin 16, and having a bit 17 to engage the recess 1 .1,and dog the bolt in full outer position. A spring 18 fixed to the lever and pressing against the top of Figure-3 is a section on the line 3-3 of the casing,- furges the lever 15 downward, I -*so that when the bit 17 enters the recess 14, the" bolt cannot be drawn {back without, the'li-fting of the lever15. 7
with a projection -20,-*to engagethe lever 15, and lift'it, and this plughas'a key slot21i The bo'lthas its end bevelledor rounded, ias shown at 22;, and a -W1Cl notch or recess 23 to Thenumeral 19 indicates the key-plug,
on top, in-frontof the-shoulder 1 1. Along;
i the top the lever 15 has an edge 24 extendin .towards the closed backofthe casing 1. *Ac acent the extension 12, in the position' of the bolt shown in Figure 1, the closed back? of the casingihas a pairof slots 25 and'26,
running together downward: at an angle' and 27 is asinall knob or head on a pin 28 pro jecting through'the slots and under the edge 24 of the lever, a collar 29 fixed on the pin 'insidethe casing preventing the removal of 1 this head and pin. On the end of the extension'12 isa finger 30 passing up beyond the rim 2 of the lever, and in position to push upon the inner end of the pin 28 and move 26 hasa notch or recess 31; and the casing 1nay be thickened or reinforced at 32 to enable the slots 25 and 26 to be cut therein, and support the stud- 5. Holes 33 enable the casing to be screwed or bolted on the door, and
34 is a fastening device for the stud 5.
When the latch engages the notch 14 with its bit 17, the bolt isheld in full projected position. To withdraw the bolt from without, one must use a key to turnthe plug 19,
the head 27. The upper extremity "of the slot and cause the projection .20 to liftthe lever 15." Then by turning the knob, the gear 9 moves back the bolt 2. The bolt can be retracted from within the room or enclosure by using the head 27 pushing it into the slot 25 to make the pin 28 lift the latch 15, so that the bolt can be shot back by the knob 11.
WVhen the latch 15 is lifted the spring 6 acts to move back the bolt just enough to carry the shoulder 13 past the bit 17; the" spring'being set for this purpose. when thelatch is released, the bit drops in Then front of shoulder 13. Now the bolt can be fully retracted by merely turning the knob on the inside or outsideof the room, and the lock can be set to permit this mode of operation at any time by moving the head 27 up along the slot 25 and then releasing f the head; sothat one leaving the room can close the door, and reopen it Without a key. I
If, with thebolt in the position shown, or
partly withdrawn and with thebit 17 engaging the shoulder13, one wishes to set" I the look, upon leaving the room, so that the door cannot be opened from the outside ex cept by a key, he first retractsthe bolt fully and opens the door and moves the head along the slot 26 till the pin reaches recess" 31, thus lifting the latch holding back g lieve to be new and desire, to secure and pro tectby Letters Patent of the United States 1s:-
LA lock comprising a bolt, rack teeth on the bolt, a gear meshing with said teeth, a spring tending to urge the bolt to partly projected-position, a latch, ashoulder on the bolt to be engaged by the latch when the bolt is in partly projected position, a head to disengage the latch from the bolt, a casing having V-shaped slots running together to guide the head, the bolt having a recess adjacent the shoulder, so that, when the latch is disengaged from the bolt, the bolt can be ,moved to full projected position to be engaged and secured against withdrawal by said latch, and a finger on the bolt to move the head along one of said slots, to enable the latch, to be released from the head when the bolt is moved to full projected position.
