The opening 18 in the plate or disc 17 is provided with diametrically opposite V- shaped projections 22 forming opposed shoulders 23 which are engaged by the tape or extension 19 to turn the knob 2 to the left in Figure 3 and thus, by engagement of the pins'13 and 14, withdraw the sliding bolts hereinafter described when the key is turned to unlock the door from the outside. It will. be evident moreover that owing to the shape of the opening 18 the knob may be turned by hand in the s ame direction, that is to the left in Figure 1, independently of the key and its extension 19 which would otherwise prevent the knob being turned from inside the door unless the key were in the lock to release the keyfcylinder.
Connected by a rod 24 or the like to one of the aforesaid arms 7 on the bolt-operating element 6 is an upper vsliding bolt 26 which slides in a suitable' guide 27 -on the door and is adapted to eng-age a corresponding. socket or retainer 28 on the door frame. A lower sliding bolt 29 may be similarly connected by a connecting rod 31 to the second or lower arm 7 of the bolt-operating element, and either or both of these bolts may be disposed in a vertical position or they may extend horizonally between the door and door frame as shown in the case, of the lower bolt in Figure 1. In the latter 'case the rod or connection 31 between the bolt and bolt-operating element is attached at its lower end to one arm of a bell crank lever 32 or the like. The other arm of this lever is connected by a short horizontal rod 35 with the lower sliding bolt y29 so that the circumferential movement of the knob carrying the bolt-operating element is converted into the horizontal sliding movement of the bolt. v
The sliding bolts are normally forced into their sockets or retainers 28 by the action of a suitably larranged spring 33 which may be connected at one end to one arm of the bolt-operating element or one of the connecting rods and at its other end to the door as in Figure 1. By making one end of the spring detachable it may be disconnected so that the sliding bolts 26, 29 will remain in their Withdrawn or inoperative position when the door is open, and the latch lock may, if desired, be used independently of j said bolts.
In accordance with the invention each aforesaid sliding bolt preferably comprises a tubular casing 34 (Figure 6) within which a rotatable member or core 36 vis freely casing 34, come into contact with the rotatable member 36, which will thus oscillate with the saw and render it impracticable to cut through the bolt. This special construction of the bolt constitutes a feature of the invention and its utility will be readily apparent.
The invention operates as follows. the door is to be locked the bolts 26, 29 are held back in their withdrawn position against the action of the controlling spring 33 by turning either the keyA or the knob so that the bolt-operating element 6 is turned with the knob owing to the engagement of the pins or projections 14, 13. As the door closes and the key or knob is released the V latch 37 is shot in the ordinary way by the pressure of the usual internal spring in the latch casing 3. At the same time the spring 33 causes the bolts 26 and 29 to automatically shoot into their sockets or retainers 28 thus securely locking the door ata number of separate points. When the key 16 of the lock is turned to withdraw the latch 37 and open the door from the'outside the bolts 26,
29 are also withdrawn against the actionof To open the door from the inside the knob 2 may be independently turned by hand in the direction of the arrow in Figure 3, the opposed shoulders 23 of the disc 17 thereby moving away from the key cylinder eXtension 18 which remains fixed until the key is inserted in the lock.
The invention, which may be readily applied to existing door locks of the kind indicated, provides a reliable fastening for the doors of lock-up shops and the like, where owing to the door being closed from the outside it is not practicable to operate internal bolts by hand.
It will be obvious that the particular construction described and illustraed may be altered or modified in various respects without departing fromthe spirit and scope of the invention 'as defined by the appended claims.
Having now described my invention what I claim as new and desire to secure by Letters Patent is I.
1. In a combined lock and bolt device for doors, the combination with a latch lock having a rotary key cylinder at its outer side and a metal tape or extension projecting inwardly from said cylinder, of a rotary knob or handle at the inner side of the latch lock,
and a plate on the end of said knob to receive the end of said key cylinder extension, said plate having an opening therethrough to accommodate the key cylinder extension, and diametrically opposite projections on the wall of said opening forming pairs of opposed shoulders to be engaged by said eX- tension.
2. A combined lock and bolt device for doors comprising a latch lock having means whereby its knob or handle at the inside of the door may be turned by a key from the outside thereof, a co-operating sliding bolt or bolts disposed at a distance from said lock, an outstanding projection on said knob or handle, a bolt-operating element freely mounted on the knob and operatively connected with .said bolts, and a second projection carried by said bolt-operating element and adapted to be engaged by the said projection on the knob whereby the bolt or bolts may be moved by the turning of the key in the lock.
3. A combined lock and bolt ldevice for doors comprising a latch lock having means whereby its knob or handle at the inside of the door may be turned by a key from the outside thereof, a co-operating sliding bolt or bolts disposed at a distance from said lock, a projection on said knob, a bolt-operating element freely mounted on said knob and operatively connected with said bolts, a second projection carried by said bolt-operating element and adapted to be engaged by the projection on the knob whereby the bolt or bolts may be moved by the turning of the key in the lock, and means whereby said knob may be turned by hand to withdraw the latch and bolts independently of the turning of the key.
4. A combined lock and bolt device for doors comprising in combination a latch look having means whereby its knob or handle at the inside of the door may be turnedby a key from the outside thereof, co-operating sliding bolts disposed above and below said lock and at a distance therefrom, an outstanding projection on said knob, a bolt-operating element comprising a plate which freely surrounds the knob and has outstanding arms, a second projection carried by said bolt-operating element and adapted to be engaged by the first named projection on the knob, and connecting rods operatively connecting said arms of the bolt-operating element with said sliding bolts for the purpose set forth.
5. A combined lock and bolt device for doors comprising a latch lock having means whereby its knob or handle at the inside of the door may be turned by a key from the outside thereof, a co-operating sliding bolt or bolts disposed at a distance from said lock, a bolt-operating element comprising a plate which has a central hole to freely accommodate said knob having an open mouth on one side of said plate and a detachable section adapted to fit into said open mouth to close` said hole after the plate has been placed on the knob, connecting rods operatively connecting the bolt-operating element with said bolts and engaging abutments or projections on the knob and the bolt-operating element whereby the latter may be turned in one direction with the knob, and the knob may be turned in the opposite direction independently of the bolt-operating element.
6. A combined lock and bolt device for doors comprising a latch lock having means whereby its knob or handle at the inside of the door may be turned by a key from the outside thereof, a co-operating sliding bolt or bolts disposed at a distance from said lock,
a bolt-operating element freely mounted on said knob, engaging projections on the knob and bolt-operating element, a lever pivoted on the door and connected to one of said bolts which moves in a substantially horizontal plane, and a rod connecting said lever with the bolt-operating element for the purpose set forth.
7. A combined lock and bolt device for doors comprising in combination a latch lock having means whereby its knob or handle at the inside of the door may be turned by a key from the outside thereof, a co-operating sliding bolt or bolts disposed at a distance from said lock and operatively connected with said knob whereby the turning of the latter will withdraw said bolt or bolts, and a controlling spring adapted to normally shoot said tainers on the door frame.
In testimony whereof I aiiiX my signature.
