IMPROVEMENT IN PADLOCKS.
Specification forming part of Iietters Patent No. 127,695, dated June 11, 1872.
To lwhom it may concern:
Be it known that I, BERNHARD KENsLER, of Hartford, in the county of Hartford and State of Connecticut, have invented an Improvement in Padlocks; and I do hereby de- A clare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawing makin g part of this specification, in which- Figure lis a view of the interior of the-lock, as seen by removing the front plate, showing the shackle locked. Fig. 2 is a similar view of the same parts, showing the shackle unlocked. Fig. 3 is a section through the lockcase taken in the course of line y, Fig. l. Fig.
v 4 is a perspective view of the tumblers.
vibrating hooked tumblers, the latter having T-shaped slots through them, which receive a stud on said sliding bolt, as will be hereinafter explained. Y
The following description of my invention will enable others skilled in the art to under- A stand it.
In the accompanyingdrawing, A represents the case of the lock, and Al an extension thereof, to which a chain-link is pivoted. B represents the pivoted shackle, which is constructed with a slotted and hooked nose, a, on its freeend that enters an opening through the fiat end of the case A. The works inside of the case consist principally of two tumblers, b b, and a sliding bolt, g. The tumblers are separated by a plate, t, which is held in place by means of studs f e rising from the back of the lock-case, and these two tumblers are pivoted to the stud f, so as to vibrate freely there- 0n. Each tumbler b has a hooked portion, b2, -which, when the shackle is locked, engages with the hook on the nose thereof, as shown in Figs. 1 and 2. The broad 'part of each tumbler is slotted in a peculiar manneri. e., the
slot b1 is T-shaped, and receives through it a stud, c, which is on the bolt g. The hooked end b2 of one of the tumblers b has a bar, w, formed on it, as shown in Fig. 3, against Which the spring o presses, which holds the opposite end of this tumbler down upon the stud c. The spring o of the other tumbler b presses directly against the back of its hooked portion. These springs, as well as the stronger one i, are coiled around the stud n. The latter spring (i) presses( forcibly against the rounded nose of the shackle B when the latter is locked, and when it is unlocked this spring throws out the shackle. The bolt g slides against the at side of the end of the lock-case, and is guided by a boss, s, on the back of the lock-case. y This bolt is forced forward through the slotted nose a of the shackle B by a spring, e, which is applied to the stud c. The nose of the bolt g is beveled, and when it is through the nose of the shackle it extends between the hooked heads of the tumblers, which, being separated, as shown in Fig. 3, allow the bolt to assume such a position.
When the key is applied on the stud c and turned, the lirst movement forces up the broad ends of the tumblers b b until the stud c 0n the bolt g is in line with the oblique portions of the T-shaped slots b1, after which, as the bolt g is moved back, the stud c passes into said oblique portions b1, and further raises the broad ends of the tumblers. Thus it will be seen that the tumblers are first lifted directly by the key, after which they are lifted by the action of the stud c and oblique slot.
It is very importand that a railroad padlock should be so constructed that it cannot be unlocked by striking it forcibly againstl an objecta practice which is frequently resorted to by persons who are not in possession of the keys of the locks. The shackle of the lock, which I have herein described, cannot be released from its bolt and tumblers by concussions, for the reason that the bolt is securely held in place when locked by the straight portionsof the slots b1, into which the stud c is The combination, With the shackle B of a padlock, of pivoted hooking tumblers b2, slotted as at b1, -and a rectilinear moving bolt, g, having a stud, c, extending from it into the slots ofthe tumblers, whereby two or more tumblers, slotted as described, may be used in a padlock, which is constructed, organized, and operated as set forth.
' BERNHARD KENSLER.
