BERT W. WOLFE .AND'CLINTON L. WOLFE, OF BROOKLYN, NEW YORK.
COMBINED LONG BOLT AND KNOB-LOCK.
- Specification of Letters Patent.
Patented Nov. 9 1915.
Application filed October 29. 1913. Serial No. 798,034.
To all whom it may concern Be it known that we, BERT W. WOLFE and CLINTON L. WOLFE, citizens of the United States, both residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Combined Long Bolts and Knob-Locks, of which the following is a specification.
This invention relates to locks having a latch bolt and a dead bolt, and particularly to that class of said locks in which the spindle is composed of two parts acting independently upon the latch and having means forlocking and unlocking one part at will, so that the latch bolt may be retracted by both the inner and outer knobs, orby the inner knob alone. as may be desired; means being provided for bringing the knob look under control of the dead bolt, so that p'os-' session of the key required to operate the dead bolt will enable the release of the knob.
. lock, so that the latch may be retracted from the outside as well as the dead bolt.
The invention further relates to so-called long bolts or bolts having a great length of projection for considerations of security, and another feature of the invention, therefore, consists in means whereby a long throw can be imparted to the dead bolt without an excessive angular movement of the key, and whereby said dead bolt will be securely dogged or locked against retraction when thrown to locking position.
A further feature of the invention consists in providing a single operating means for the dead bolt and adapting the same to be actuated by either the inside stationary or removable key or the outside removable key at will, each key operating independentlv of the other.'
The invention will be fully understood upon reference to the accompanying drawing. in which- Figure 1 is a side view of the lock with a.
portion of the casing removed. and Fig. 2 is a perspective view of the dead bolt operating member partly in section.
1 represents the lock casing, 2 the face plate. 3 the latch bolt, and 4 the dead bolt.
The latch bolt is adapted to be retracted by' either of two rocker arms 5 (one only being shown) mounted upon the spindle 6, which is preferably divided in a well-known manner so that each part carrying one knob, can
operate its rocker arm independently of the other. One of the rocker arms, namely, that shown in Fig. 1, is provided with a known construction of knob lock consisting of the notch 7 in the rocker arm and the sliding dog 8. The dog. 8 may be forced into en gagement with the notch 7 by means of the push button 9 and it may be retracted through means of the push button 10 acting through the lever 11. These parts have existed in principle as well as details of construction in locks heretofore known and need'not be further described.
To avoid the complication of having inde-' pendent means for retracting the latch bolt by the key that operates the dead bolt, the present invention embodies a means for throwing out the knob lock in case it should be left in looking position when it becomes necessary to open the door from without. Accordingly, the dead bolt 4 is provided with a cam 12 which acts upon a lever 13 fulcrumed at 14 and carrying at one end the friction roller 15, while its other end 16 projects into retracting relation to the dog 8. With this construction, longitudinal movement of the bolt 4 will impart upward movement to the lower end of lever 13 and dog-retracting movement to its upper end,
so that after withdrawing the dead bolt 4. the latch bolt may be retracted by turning the knob on the outside of the door. The cam 12 operates the lever 13 on its outward throw as well, as on its inward throw. This not. only avoids complication that would be required to render the cam operative in one direction only, but insures the advantage of preventing an unintentional lock-out when temporarily closing the door behind one, and also renders the lock safer, in that it accustoms the user to positively lock the door upon leaving.
To develop along throw to the bolt 4, the lock is provided with an operating arm 17 carried by sleeve 18 mounted upon and adapted to be rotated in either direction by two independent hubs 19, 20, one of which receives the outside or removable key, while ,the other receives the inside-or permanent key. These hubs are provided. respectively,
lOt
hub. The arm 17 connects with the bolt 1 through means of a link 21, with which said arm forms a toggle lever, and. With the result that the movement is materially multiplied from a relatively short are of movement in the sleeve 18. A further advantage arising from this toggle lever control is the fact that therconnections becomes self-locking when the parts move into or slightly beyond alinement, so that any force applied to the bolt 4 in the direction of retraction otherwise than through the intended connections, will be effectively resisted \Ve claim 1. In combination with a latch-bolt, independently operable outer and inner knobspindle hubs for controlling said latch bolt, a knob-lock for engaging the outer knob spindle hub, a dead bolt, means for operating it, and a connection through which said dead bolt retracts the knob-lock.
2. In combination with a' latch bolt, independently operable outer and inner knobspindle hubs for controlling said latch'bolt, a knob-lock for engaging the outer knobspindle hub, a dead bolt, means for operating it, and a connection through which said dead bolt retracts the knob-lock; said lastnamed connection being located to act upon the knob-lock only when the dead bolt is in an intermediate position, whereby the knob lock may be left effective during the retract ed position of the dead bolt.
3. In combination with a latch-bolt, in-- dependently operable outer and inner knob spindle hubs for controlling said latch bolt, a knob-lock for engaging the outer knobspindle hub. a dead bolt. means for operating it, and a connection through which said dead bolt retracts the knob-lock; said knoblock being adapted to rest in and having positive means for moving it to its respective positions of engagement with and disengagement from the knob-spindle hub, and the dead bolt connection being located to act upon the knob-lock only when the dead bolt is in an intermediate position, whereby the knob-lock may be left efi'ective during the retracted position of the dead bolt and disengaged from the knob spindle by movement of the dead bolt from either retracted or projected position. v
4. In combination with a latch bolt, a controlling knob spindle for said latch bolt, and a knob lock for said spindle; a dead bolt, means for operating it, and a connection through which said dead bolt retracts the knob lock, consisting of a cam upon the dead bolt and a suitable fulcrum. lever engaged by said cam and adapted to impart retracting movement to said knob lock.
5. In a lock having a latch bolt and a dead bolt, a knob spindle controlling the latch bolt, a knob lock having manually operated means for positioning it in or out of looking relation to the spindle at will, an intermediately fulcrumed releasing lever having one end adapted to move said knob lock out of locking position, and having its other end projecting in proximity to the dead bolt, and a cam carried by the dead bolt in position to impinge against the end of the releasing lever in both directions of dead bolt movement.
6. In a lock, the combination with a latch bolt, a knob spindle for controlling said latch bolt, a knob lock movable into and out of locking relation to the knob spindle, a lever suitably fulcrumed in relation to the knob lock for moving it out of locking position, a dead bolt having a cam engaging said releasing lever in the direction to withdraw the knob lock, and means for controlling said dead bolt, consisting of a suitably pivoted arm having a link connection with the dead bolt, and forming with said link, a toggle lever.
7. In a. lock, the combination with a dead bolt, of a pair of independently rotatable hubs adapted to be rotated from within and without the door, respectively, a sleeve rotatablv mounted upon both said hubs and provided with an arm having operating connection with the bolt: and overlapping shoulders and segmental lugs mounted on said sleeves and hubs, respectively, and having lost motion between them, permitting either hub to impart rotation to the sleeve in either direction independently of the other hub.
8. In a lock, the combination with a dead bolt, and means for operating said dead bolt either from within or without the door, comprising a pair of independently rotatable hubs, a sleeve mounted on said hubs and carrying an arm, and a link connecting said arm with the dead bolt; said hubs and sleeve being provided with interengaging segmental lugs spaced apart to permit partial rotation of each hub independently of the sleeve.
