PADLOCK.
SPECIFICATION forming part of Letters Patent No. 223,528, dated January 13, 1880.
Application filed June 9) 1879. 7
My invention consists in the peculiar construction of certain parts, and in their combination with themselves and with other parts or devices, as hereinafter more fully described,
- In the accompanying drawings, Figure ,1 is
a front elevation of a look which embodies my invention. Fig. 2 is a like view with. part of the case removed and the parts represented as locked. Fig. 3 is a like view of the same represented as unlocked. Fig. 4 is an inside I view of the part of the case which is removed from Figs. 2 and 3. Fig. 5 is a transverse section of said lock on line 3 y of Fig. 2. Fig. 6 is a transverse section of the cam-cylinder on line as a; of Fig. 3, showing the manner of coupling it to the key-cylinder; and Fig. 7 is an end view of the caiacylinder.
A A designate the two halves of the lockcase; B, the shackle, preferably provided with a spring, 0, for throwing it open, as is common in padlocks. If desired, a sliding or other shackle might be substituted for the swinging shackle B without materially changing the other features of the invention.
I prefer to make the case practically a solid one, and'I divide it into two halves, A A, on one side of the middle line, and for convenience of putting in some of the parts I form a flange or lip, k, on the half A, which shuts over the edge of the other half, A, as shown in Fig. 5. I also make a cap, E, at the lower end for closing that end of the case. The two halves A A are put together, and then bored out longitudinally and recessed transversely to receive other parts, hereinafter described.
C designates a cylinder or key-hub fitted in the longitudinal bore of the case, slotted longitudinally to receive aflat key, and provided side of the key-cylinder, is provided with a set of spring-actuated pins for joint action with the pins in the key-cylinder and their recesses, as indicated by broken lines in Figs. 2 and 3, to lock the key-cylinder immovably in its place in a well-known manner by wellknown means, so that it is considered unnecessary to describe the same except in general terms.
Ihave specified the key-cylinder containing but one set or series of pins; but the sets may be duplicated as many times as may be d'esiredrand any other form of pius--as, for instance, threaded or grooved instead of plain, and flat instead of roundmay be substituted, if desired. i The key-cylinder C is reduced in size at its lower end to allow a collar or circular flange, n, of the cap E to enter the bore of the case. (See Figs. 2, 3, and 5.) The neck or lower end of the key-cylinder C bears a stop-pin, a, and a portion of the flange n is cut away, as shown in Fig. 5, far enough to allow the cylinder to make one-quarter of a revolution, while the solid portions of the flange act in connection with the stop-pin a. to limit the motion of the cylinder to said quarter of a revolution.
At the upper end of the key-cylinder, and in the same longitudinal bore of the case, there is a cam-cylinder, D, bearing a cam, b, at its upper end. The middle portion of said cylinder is reduced to receive a proper spring,f, one end of which is connected to the case and the other end to said cylinder, so as to constantly bear upon it with a tendency to turn 'it into the proper position for locking the relatively arranged so that one cylinder may" make just one-quarter of a revolution independently of the other.
The cam 12 on the cam-cylinder D engages and operates a sliding bolt, d, having a beveled end, which engages the nose of the shackle. In connection with the cam-cylinder there is a locking-pin, g, having a beveled shoulder, m, and a spring, It, Fig. 3, which spring has a tendency to throw said pin toward the camcylinder and into a notch (see Fig. 7) in said cylinder made to receive said locking-pin whenever said notch coincides with its end.
The stops which limit the movement of the key-cylinder are so placed relatively to the pins which look said cylinder in place that when the cylinder is in the proper position for being locked by the pins it is turned backward to its greatest extent, which position is represented in Fig. 5, and the coupling of the key-cylinder and cam-cylinder is so arranged that when the lock is locked, as shown in Fig.
2, a forward movement of the key-cylinder necessitates a like-movement of the cam-cylinder.
To unlock the lock a key properly formed to control the pin-tumblers in such manner as i to release the key-cylinder is inserted, when it is turned in the direction of the arrow in Fl 6, thereby carrying said cylinder, together with the cam-cylinder, one-quarter of arevolution from the position shown in Fig. 2 into the position shown in Fig. 3. In doing so the cam b withdraws the sliding bolt out of the notch in the nose of the shackle, and also the f notch in the edge of said cam-cylinder is brought in front of the end of the locking-pin g, when its spring it forces it into said notch and locks the cam-cylinder immovably in its place, and with the locking-bolt d unlocked, all as shown in Fig. 3. If desired to'withdraw the key, the quarter play in the slack coupling before described allows the keycylinder to beturned backward to its former position, the key removed, and the key-cylinder to be again locked immovably in the case, while the cam-cylinder, shackle, and connecting parts remain unmoved in their unlocked position.
In order to lock the shackle, it is only necessary to press it into the case, when its nose will en gage the beveled shoulder in of the locking-pin gand withdraw it from the cam-cylinder, thereby releasing said cylinder and allowing its spring to return it to its former position, thus moving the cam 11 to throw the sliding bolt into engagement with the shackle, all as shown in Fig.2. When the springfthus acts upon the cam-cylinder to move it back after the key-cylinder has been locked, said movement takes up all the slack or play in the coupling, so that, upon reinserting the key to unlock the lock, the cam-cylinder will move with the key-cylinder, as before described.
In case a lock is desired from which the key cannot be removed when the shackle is unlocked, then the cam-cylinder may be formed solid on the endof the key-cylinder without any slack coupling, and the other parts will operate as before described.
In the lock as described, if the key-cylinder is not turned back by hand before theshackleis forced into the case, then the spring f will move both the key-cylinder and the ca1n-cylinder back to their proper position for locking, the same as though they were one cylinder. Thus it will be seen that the key-cylinder is so arranged as to be spring-aetuated, if desired to so use it.
By making the casein two halves divided position, might be partially rotated by a spring acting mediately through the locking-bolt, but which cylinder was also provided with a spring for throwing it longitudinally, so as to take it out of the position in which the spring first named could act upon it. Both of these prior devices are hereby di-sclaimed.
I claim as my invention 1. In a padlock, the cylinder of a pin-tumbler lock and suitable connectin glock-in g mechanism, in combination with a spring acting directly upon said cylinder to partially rotate it, and so combined therewith that the cylinder is always under theinfluence of the spring in all the various changes in the position of the parts, substantially as described, and for the purpose specified.
2. In a padlock, the combination of the nose of the shackle, cam-cylinder D, spring f, cam b, and sliding bolt (1, substantiallyas described, and for the purpose specified.
3. The combination of the cam-cylinder D, spring f, cam b, sliding bolt (1, spring-actuated locking-pin g, and nose of the shackle, substantially as described,and for the purpose specified.
4. In a padlock, the spring-actuated camcylinder, operating suitable mechanism for locking the shackle, in combination with the rotating key-cylinder and the slack-couplin g, substantially as describechaud for the purpose specified.
5. In a pin-tumbler lock, the combination of suitable locking mechanism, a rotating cylinder operated in one direction by a key, a spring acting to return said cylinder in the opposite direction, and suitable mechanism for locking said cylinder against the action of said spring when the cylinder is acting upon the sliding bolt to hold it in an unlocked position, substantially as described.
6. The lockcase A, divided longitudinally, in combination with the rotating key-cylinder of a pin-tumbler lock lying partially on each side of the dividing-line of said case, and with its axis parallel thereto, substan- ELISHA MIX, H. B. PL MB.
