LOCK.
SPECIFICATION forming part of Letters Patent No. 700,106, dated May 13, 1902. Application filed June 15, 1901, $eria1 No. 64,739. (No model.)
To all whom it may concern:
Be it known that we, EMIL \VEBER and FRANK O. FREY, citizens of the United States,
residing at and whose post-office address is' 1933 Court street, Baker City, in the county of Baker and State of Oregon, have invented new and useful Improvements in Locks, of
which the following is a specification.
Our invention relates to looks of the class which are especially adapted for use as doorlocks; and its primary object is to entirely avoid the employment of springs and to thus.
greatly simplify this class oflocks.
A further object of the invention is to pro- :5 vide a lock which cannot be opened by any means other than a key specially constructed and adapted for the purpose.
The invention com prises a gravity-operated bolt, a tumbler coactin g therewith and adapted to be oscillatedby a key, pins within the tumbler, and a double-acting locking-dog forcontrolling the movement of the tumbler.
The construction of the improved lock will be fully described hereinafter in connection with the accompanying drawings, which form part of this specification, and its novel features will be defined, and particularlypointed out in the appended claims.
In the drawings, Figurevl is an elevation of a lock embodying the invention, the coverspective of the oscillating tumbler forming an element of the lock. Fig. 4 is a vertical sectional view of the tumbler, and Fig. 5 is a view in perspective of the locking-dog.
The reference-numeral 1, designates the lock-casing, the face-plate 2 of which is formed with the usual bolt-slot'S. Within the casing is pivotally secured by a pin 5 a'swinging quadrant 4, formed withtwo segmental slots 6 and 7, through which extend stop-pins S 5 and .9. The quadrant 4 is also provided with an oblong recess 10, within which extends a lever 11, mounted upon a revoluble sleeve 12, through which the knob-shaft is adapted to extend. The ends of the recess 10 are curved to permit the required movement of the lever.
13 designates the lock-bolt, provided with a stem 14, extending through an opening in secured to the casing.
the front face of the quadrant 4 into the slot 7, where it is secured by a cross-pin 15. The inner edgeof the quadrant 4 is formed with a segmental seat 16, Within which is adapted to fit a segmental tumbler 17, mounted upon an oscillating sleeve 18, formed with a keyslot 19. The movement of the tumbler 17 is limited by a stop-pin 20, against which the curved face 21 of the tumbler bears, and said tumbler is formed with a shoulder 22, adapted to be engaged by a dog 23, pivotally The dog 23 is formed with a segmental recess providing a shoulder 24'for a purpose hereinafter explained. The tumbler 17 is formed with a plurality of parallel openings 25, within each of which is arranged a movable pin 26, said pins being suitably guided, preferably by lugs 27, movin gin recesses formed in the walls of the openings 25.
The operation of the mechanism above de- 7 scribed may be explained'as follows: As will be apparent from the illustration in Fig. 1, the weight of the quadrant 4 holds the bolt 13 normally in its projected or locked position, and the engagement therewith of the tumbler 17 (the latter being held by the engagement'of the dog 23 with the shoulder 22) maintains the bolt in locked position. The pins 26 are of varying length and any desired number and are adapted to be lifted by the contact therewith of a suitably-notched key. The lifting of the pins by the insertion of the key within the key-slot 19 forces their outer ends against the under surface of the dog 23 .to disengage the latter from the shoulder 22 and permit the sleeve 18 and the tumbler 17 to be turned to the position shown in Fig. 2. After the tumbler has been thus turned the bolt may be withdrawn by swinging the quadrant 4 inward upon its pivot through the medium of the lever 11, carried by the sleeve 12,
the latter being oscillated bythe turning of the knob-shaft extending therethrough.
An important feature ofthe-invention is the double-acting dog 23,'havin g the shoulder 24, as said dog not only normally engages the quadrant 4 to hold the parts in locked poroo sition, but also serves as a security against unauthorized opening or tampering with the look. If any key or instrument other than the key specially constructed for the purpose is inserted into the key-slot 19, all of the pins 26 will not be lifted and the dog 23 will be so tilted that its shoulder 24 will engage the inner projecting curved edge 28 of the tumbler. It will thus be seen that the lock is secure and cannot be picked or tampered with.
A distinguishing characteristic of the improved construction is that we entirely avoid the use of springs for projecting or retracting the bolt.
While we have shown a lock in which a revoluble sleeve is employed in connection with a knob, it is obvious that a pivoted lever or latch for raising the quadrant 4 may be readily substituted in lieu of the lever and sleeve shown. This construction we may find desirable or convenientin connection with storedoor locks or where a knob would not be conveniently used.
The lock constructed as above described is of few parts, so combined as to insure ready operation and durability in use.
We claim- 1. The combination with a quadrant provided with a latch-bolt and a segmental seat, of an oscillating sleeve having a key-slot and provided with a segmental tumbler to normally engage said seat, said tumbler having a shoulder and parallel openings having recesses and extending from the rear of said shoulder to the key-slot, pins of varying length movably mounted in said openings and provided with lugs to work within said recesses, a stop-pin to limit the movement of said tumbler, and a dog to engage said shoulder to hold the tumbler normally in engagement with said seat, and having a segmental recess providing a shoulder to engage the inner projecting curved edge of said tumbler when a false key is inserted into the key-slot.
2. The combination with a casing, of apivoted quadrant adapted to swing therein, provided with segmental slots (5 and 7, an oblong recess and a segmental seat, pins extending in said slots to limit the movement of the quadrant, an operating-lever working within the recess, a latch-bolt having a stem extending through an opening in the quadrant into the segmental slot 7, a pin holding said latchbolt therein, an oscillating sleeve having a key-slot and provided with a segmental tumbler to normally engage said seat, said tumbler having a shoulder and parallel openings having recesses and extending from the rear of said shoulder to the key-slot, pins of varying length movably mounted in said openings and provided with lugs to Work within said recesses, a stop-pin to limit the movement of said tumbler, and a dog to engage said shoulder to hold the tumbler normally in engagement with said seat, and having a segmental recess providing a shoulder to engage the inner projecting curved edge of said tumbler when a false key is inserted in the key-slot.
In testimony whereof we aifix our signatures in presence of witnesses.
