Letters Patent No. 72,166, dated December 17, 1867.
IMPROVEMENT IN PADLOGKS.
TO ALL WHOM IT MAY CONCERN:
Be it known that I, GIIARLES J. GLEMENTS, of the-city, county, and State of New York, have invented an Improved Lock; and I do hereby declare thatthe following is a full and exact description thereof, reference being had to the accompanying drawings, making' part of this specificationp Figure 1, being a plan of a. padlock, provided with my improvements; the top plate of the case being removed to show the interior construction, and the parts being in position as when locked.
Figure 2, an edge view of the same. 7
Figure 3, a view corresponding with that in fig. 1, except that the parts are shown in position, as when unlocked.
Like letters designate corresponding parts inall of the figures.
The main feature of my improvement consists in theemployment of a hinged guard-plate, acting in connection with notched tumblers, to prevent their turning around for unlocking till their respective notches are brought opposite to the sairl plate, which then swings into said notches, and thereby allows the bolt to be thrown. i p
Let A represent the cylinder of the lock, and g the ky-hole therein. The tumblers a a are located transversely therein, and turn with the cylinder, :15 indicated by comparing the positions in figsl and 3. These tumblers are all pivoted at one end upon a pin, l, and the other end is free to be depressed, by pushing the key down into the key-hole. The free ends of all, however, are held up to an even position by springs, 12 12, underneath, as shown clearly in fig. 2. In front of the tumblers a dis located thc guard-plate B, being a. thin plate,
pivoted'at one end, 6, while the other end is connected by a plate or link, C, with the cylinder A, the linkbeing pivoted to th'eguard-platc at e, and to the cylinder at d, substantially as represented. The guard-plate may have a guide, m, in which it moves, to keep it securely in the right position. The front ends of the tumblers have series of shallow or false notches, at regular intervals, along the entire width thereof; though these, if the guard-plate enters them, will not allow the tumblers to turn. But each tumbler has one deep notch, in some position, in its edge, as indicated by black shade in fig. 2. Those notches in the different tumblers are at various distances from the'upper edge thercof,as indicated, so that the diiierent tumblers have to be depressed, some more than others, in order to bring all their notches exactly opposite to the edge of the guard-plate, which is just thick enough to enter the notches. All the notches must be brought precisely opposite to the guardplate before the cylinder can turn; and the different steps of the bit 2', of the key G, fig. 2, for the several tumblers, project, each just far enough to bring the notches into position to receive the guard-plate; thus the key turns the cylinder A, which has the bolt M attached to it, and swings the same out of the hook or loop of the lock-bar or staple H. At the same time, the motion of the cylinder draws upon the connecting-link C,
and thereby throws the guard-plate B into the notches of the tumblers, as indicated in fig. 3. The tumblers are thus securely held in position for locking again, without the use of the key. This is efi'ectedby the lockstaple, ,when it enters the lock again, its point, it, striking and pressing against a stud,]), of the cylinder, which starts the cylinder back toward the position for locking. "he remainder of the movement is continued automatically by a spring, f, pressing on the stud D. A spring, r, pressing on a stud, s, of the lock-staple, throws the staple out, as soon as the bolt is freed from it in unlocking. The notched ends of the tumblers are represented as bevelled or oblique. This allows the guard-plate to enter and pass out again, with less movement than otherwise.
These improvements are applicable to other kinds of locks, as well as that represented. It makes a very secure look, as well as simple, cheap, and durable. I I
The bevelled-edge tumblers also give greater depth of true groove, acting on the guard-plate, and act as wedges upon the edge thereof. i
What I claim as'my invention, and desire -to secure by Letters Patent, is-- The guard-plate B, arranged and operating in combination with the tumblers (to, substantially as and for the purpose herein specified. V
The above specification of my improved lock signedby me, this 1st day of August, 1867.
