SPECIFICATION forming part of Letters Patent N 0. 723,539, dated March 24, 1903. Application filed September 24, 1902. Serial No. 124,626. (No model.)
To all whmn it may concern:
Be it known that I, OASSIUS 'W. MARR, a citizen of the United States, residing at Alliance, in the county of Stark and State of Ohio,
have invented a new and useful Look, of which the following is a specification.
My invention relates to a lock in which the bolt or latch is operated by the rotation of a plate or disk, which disk is in turn rotated by a key which properly alines a series of stop-levers; and the object of the invention is to permit a great number of variations to be made in the key necessary to open the lock by merely changing the relative location or the angle of the several levers. I attain this object by the mechanism and construction illustrated with reference to a padlock in the accompanying drawings, in which Figure I is an interior view of the lock with one side removed; Fig. II, a section on line a; at, Fig. I; Fig. III, a side view of the end of the key; Fig. IV, a section showing the keygnide, and Fig. V a fragmentary view showing a non-continuous groove in the case.
Similar numerals refer to similar parts throughout the drawings.
The rotatable disk 1 is pivoted to the case 2 of the lock in any well-known manner, and on one side of the disk is the projecting or camacting lug 3, which opens the look when the disk is rotated by throwing outward one end of the ordinary latch-bolt 4 and turning the same on its pivot 5. The disk is normally held from rotation by the lower arms 6 6 6*, &c., of the radial levers 7 7 7", &c., engaging in the radial slots Sin the back of the lock. The radial levers are pivoted inthe brackets 9 on the disk, and the inner arms operate in the radial slots 10 in the disk. The upper arms 11 11 11 850., of the levers are directed inward toward the central post 12, on which the disk is preferably pivoted, and at various angles, respectively, from the lower arms. The upper arms are normally elevated and the lower arms thereby thrown inward by the springs 13, attached on the disk. The circular groove 14 is formed in the case of the lock concentric with the disk and cutting across the radial slots, so that when the lower arms of all the levers are thrown to register with the groove the-disk can be rotated, and the lower lever-arms will travel in the groove. t If, however, one or more of the lever-arms should be thrown outward beyond the circular groove, it would enter the part of the radial slot 8 outside of the groove, and thereby stop the rotation of the disk. By reason of the various angles of the upper lever-arms with the lower leverarms it requires a difierent depression of the respective upper arms to throw the lower arms outward to register with the circular groove, and this is accomplished by providing the end edge of the tubular key 15, which telescopes over the central post, with the notches or steps 16 16 16", &c., to act on the respective inner ends of the upper leverarms. These notches or steps are varied on the key to correspond with the various depressions of the upper lever-arms required to properly aline the lower lever-arms to re,- ister with the circular groove, which depression is itself determined by the angle of the respective upper and lower arms with each other, and the character and arrangement of the notches or steps on the key can be greatly Varied to correspond to the great variety permissible in the arrangement of the levers and in the angles of the same. It will be understood that such variation of the depression required of the upper arms to properly aline the lower arms can also be made bythe relative lengths of the lever-arms and p by the location of the pivotal point of the same and that the circular groove need not be continuous, but that a series of segmental grooves all extending a suitable distance the same way in the direction it is desired to rotate the disk from the respective radial slots in the back of the case, as shown in Fig. V, will serve as well. The insertion of the key is guided by the wing 17, which is preferably attached to the disk in place of one of the radial levers, which wing enters the longitudinal slot 18 in one side of the key, so that the steps or notches in the end edge of the 'key will properly register with the corresponding lever-arms, and the disk is posi-- tively rotated when the lever-arms are thrown to register with the circular groove by action of the side of the longitudinal slot in the key against the side of the disk-wing.
If it be desired, the key-guide wing can be omitted, in which event the rotation of the disk is accomplished by the action of the sides of the end'edge notches against the sides of the lever-arms; but I prefer to use the wing, because it is more positive in action, and, furthermore, it always guides the proper insertion of the key, and the central post can also be omitted, in which event the insertion of the key in the lock is guided by the circular aperture 19 in the side thereof; -but I prefer to use the post, because it fills the central space and largely prevents the picking of the lock.
If it be desired to limit the entrance of the key into the lock to the point at which all the levers are thrown to register with the circular groove, it is done by closing the upper part of the key,'so that the end of the socket 20 formed therein strikes against the end of the circular post at the proper time to stop the key. It will be noted that the opening of this look requires two movements of the key-first, its insertion into the lock to overcome the action of the lever-springs, and, second, the turning of the key to rotate the disk.
The part of the radial slots outside of the circular groove can be omitted, if desired, without affecting the general nature of my invention, in which event the outward throw of the lower lever-arms will be stopped by the outer side of the groove, which in turn will limit the entrance of the key into the lock, and at the same time said lever-arms will properly aline to travel in the circular groove; but I would prefer to make the look as illustrated, because in this way it is more difiicult to properly aline all the levers without the use of the proper key.
What I claim as my invention, and desire name to this specification in the presence of two subscribing witnesses.
to secure by Letters Patent, is-
1. In a lock, a case having a circular groove therein and radial slots joining the groove, a disk pivoted in the case concentric with the groove, spring-controlled angular radial levers pivoted on the disk having one arm normally operating in the radial slots, and a tubular'key having notches in its edge adapted to act against the other arms of the levers.
2. In alock, a case having a circular groove therein, and radial slots joining the groove, a disk pivoted in the case concentric with the groove, a radial wing on the disk and springcontrolled angular radial levers pivoted thereon having one arm normally operating in the radial slots, and a tubular key having notches in its edge adapted to straddle the radial wing.
3. In a lock, a case having a circular groove therein, and radial slots joining the groove, a disk pivoted in the case concentric with the groove, a central post on the disk and springcon trolled angular radial levers pivoted there on havingone arm normally operating in the radial slots, and a tubular key adapted to telescope on the post and having notches in its edge adapted to act against the other arms of the lovers.
4. In a look, a case having acircular groove therein and radial slots joining the groove, a disk pivoted in the lock concentric with the groove, and spring-controlled angular radial levers pivoted on the disk having one arm normally operating in the radial slots.
5. In alock, a case having a circular groove therein and radial slots joining the groove, a disk pivoted in the lock concentric with the groove, and angular radial levers pivoted on the disk having one arm normally operating in the radial slots.
6. In a look, a case having a circular groove 1 therein and radial slots joining the groove, a disk pivoted in the lock concentric with the groove, and radial levers pivoted on the disk having one arm normally operating in the radial slots.
In testimony whereof I have signed my CASSIUS W. MARR.
In presence of HARRY FREASE, ELSIE F. MALLORY.
