LOUISE EIFFLER, OF NEW YORK, N. Y., ADMINISTRATRIX OF THE ESTATE OF CHARLES HERMANNEIFFLER, DECEASED.
Letters Patent No. 85,805, dated Janna/ry 12, 1869.
To all whomV 'it may concernI Be it known that CHARLES HERMANN Emmen,
A late of the city, county, and State of New York, during his lifetime, did invent a new and useful Improvement in Locks; and I, LOUISE EIFFLER, administratrix of the goods and effects of said CHAnLEs HERMANN EIF- FLER, deceased, do hereby declare the following to be a full, clear, and exact description thereof, which will enable those skilled in the art to makeand use thesame, reference being had to the accompanying draw ing, forming part of this specification, in which drawmg* Figure l represents a plan of this invention when the mechanism is in its locking-position.
. Figure 2 is a similar view ofthe same, showing the operation of the safety-stop, when an attempt Vis made to pick the lock.
Similar letters indicate corresponding'parts.
This invention consists in the arrangement of an additional safety-stop in combination with the ordinary lever-spring stop, and with a. series of loose tumblers in a lock, in such a manner that when, an' attempt is made to pick the lock, and the lever-spring stop is pushed back to release the tumbler-s, by the action of said leverespring stop itself, the additional safety-stop is thrown in contact with the tumblers," and the posi# tion of said tumbler-s cannot ,be disturbed or felt by any instrument or instruments introduced through the key-hole, except by the regular key, oran exact imitation thereof.
Arepresents the case which encioses the lockingmechanism.
This mechanism consists of a series of loose turn` blers, B, which are distinguished from ordinary tumblers by the entire absence of springs, and which oscillate freely on the central stud a.
A lever-'spring stop, 0,'bears on shoulders b 'of-said tumblers, and carries the same back to theirlockingposition, shown in fig. 1.
This lever-spring stop is subjected to the action of a spring, and it has its fulcrnm on 'a pivot, c, and it is provided with a projection, d, which bears on the tails of the tumbler-s, and'retains the same securely in their -locking-position, so that the operation of feeling the tumblersjsrendered exceedingly diioult.
When the leversprng stop O vis pressed back, however, by a wire, introduced through the key-hole, as shown in fig. 2, the tumblers would be entirely loose, and free to be pushed out of their locking-position, if
it were not for the presence'of the additional safetystop D. l
'This safety-stop has its fulcrum on a pivot, e, and it is subjected to the action of a spring, j, which has a tendency to throw the same in contact with the tumblers.' But when the1everspring stop O is down, as shown in iig. 1, the projection d, which acts on the tails of the tumblers, also -acts on the edge of the 'safety-stop, and presses'the same back against the action of the spring f, (see ig. 1,) leaving the tumblers free to be -raised by the action of the regular key.
By these means, a lock containing a series of loose tumblers is produced, in which the operation 'of fee1- ing the tumblers is rendered impossible, and the cost of the lock is but very little increased. f
Having thus descu'bedfthis invention,
What I claim as new, and desire to secure by Let ters Patent, is-
The additional safety-.stop D, in combination with the lever-spring stop Gand loose tumblersB,substa11 tially as and for the purpose set forth.
' LOUISE EIFFLER.
