Description

UNITED STATES PATENT OEEIOE.
THOMAS P. MURPHY, OF NEW YORK, N. Y.
BANK-LOCK.
Specification of Letters Patent No. 9,757, dated May 31, 1853.
To all whom t may concern.'
Be it known that I, THOMAS P. MURPHY, of the city and county of New York and State of New York, have invented a new and useful Improvement in the construction of Bank-Locks; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure l, Plate l, is a plan view of the lock shown with the back down and the cap oft'. Fig. 2, Plate 2, is a plan view of the bolt with the several parts attached; Fig. 3, Plate 2, is an elevation of the cases containing the racks and sectors, Fig. 4L, Plate 2, is an elevation of the racks and sectors withv parts of the bolt and pressure plate and pressure bolt in their places, Fig. 5, Plate 2, is a plan view of the racks and sectors with the pressure plate and pressure bolt in their places, Fig. 6, Plate 2, is an elevation o f a sector and pressure plate with the spring showing the action of the spring on the sectors.
The following is a description of the different parts, like letters referring to like arts.
A A A A, Fig. l, Plate 1, is the rim of the lock case.
B B B B is the lock bolt extending through the case of the lock.
C is a column or stand that supports the arbor that communicates motion to the bolt.
D is the outer end of the arbor with a squared hole in it to admit of the wrench E to turn it.
F is the cap of the case containing the racks having a top which is intended to stand Hush with the surface of the door when the lock is placed. This top having in it a mortise Gr allowing the racks to extend to the surface so as to admit of the key being app-lied directly to them.
I-I is the key formed of any convenient number of bits for the purpose of changing the form of it and varying the arrangement of the lock.
I I I I I are the racks which extend flush with the surface of the key hole in front and back nearly to the bottom of the rack case they being supported by springs and levers, the racks have on their edges next to the sectors geared teeth of the same pitch as the grading of the key.
K K K K K are the sectors that are supported in the case L by an arbor passing through their centers and allowing them to turn freely. The sectors have teeth on nearly one half of their periphery to match the teeth in the rack. They also have an opening on the opposite side to the teeth to permit the pressure plate to enter them.
M is the pressure plate supported by its bearings in the stands at O O To the pressure plate is attached the pressure bolt N, a rod extending to P, as a stop screwed on to the bolt B. The oiiice of this rod is to rise and prevent the lock bolt being pushed back when there is an attempt to pick the lock and the bolt is forced backward.
R R is a stand Jfastened to the bolt having in it a groove to allow the slide to pass freely in it.
S is the slide working in the stand having in it a small pin T to enter into holes in another slide that is supported on the rack case.
is the slide on the rack case having in it a screw passing to the side of one of the racks and partaking of its motion when the key is applied. It also has in its outer side holes to admit the pin T.
W" is a iiat spring fastened to the pressure plate either top or bottom in order to open when there is pressure applied and the sectors moved.
X is a bed piece upon which the rack case is fastened and on which the case containing the sectors slide when the bolt is moved.
In explaining the operation of the lock I will take it in the position of unlocked or when the bolt is back. The key I-I is applied by pushing it into the key hole against the racks the bitts of the key each touching the end of a rack and pressing it in to correspond with its length. The sectors when n on the pivot Z) at c which fastens it by a flexible joint to the sectors case, giving to the sectors the same motion as the lock bolt. NOW by pushing in the key and applying the wrench motion will be given to the bolt forward which carries the sector case forward so as to allow the teeth in the sectors to mesh into the teeth in the racks and when the key is Withdrawn the sectors are arranged in various positions by the racks coming out in their first position. At the same time that the key is applied the slide U is depressed and when the bolt is pushed forward the pin T in S enters one of the holes in V, thereby fastening U and S together so that in the act of unlocking the same bitt mustbe applied in order that the slide S will pass the projection on the rack case. In this position the bolt is locked.
It will at once be seen that the same key must be used in unlocking that was used to lock it, for the sectors must have their openings so as to admit the plate as well as the slide to pass the projection on the rack case.
It is a common method in picking locks to get a pressure on the bolt and then by means of a probe or any other suitable instrument arrange the interior of the lock so as to push back the bolt. In this lock it will be perceived that I have arranged the several parts so that if a pressure is applied to the bolt before the right key is pushed in that the pressure bolt will rise and touch the stop so as to prevent the bolt from being unlocked. At the same time the spring Will be affected by the motion of the sectors and open from the pressure plate and prevent its going into the sectors, the operation of which may be seen by pressing against the end of the bolt or turning the Wrench at the same time pushing down the racks with any convenient instrument. The operation of unlocking will at once be seen by thrusting in the key and turning the wrench the reverse of locking.
The following is what I claim and wish to secure by Letters Patent:
l. I claim the slides S and U and pins 'Il operated in the manner described.
2. I claim the pressure plate, pressure bolt and spring attached. to the plate arranged and operating as described or in any other way substantially the same and for the purpose set forth.
