To all 'whom 'it may concern Be it known that I, LUDWIG BEER, of the city, county, and State of New York, have invented a new and improved Safe-Lock; and I do hereby declare that thereof, which will enable others skilled in the art to make and use the same, reference being had -to the accompanying drawings, forming part of this specification, in which- Figure 1 represents a face view of the lock. Figure 2 is a-transverse section ofthe same. Figure 3 is a face view of the lower part of the Figure 4 is a face view of the the locking-cylinder.

rlhis invention relates to improvements on that kind of locks in which a slotted key is applied to shift a series of slides or plates, which serve as levers for g-cylinder, by which, the bolt is moved.
The invention consists in the application, to the locking-cylinder, of a primary lock, wlliclnlengaging a pin in a notch of said cylinder, prevents the saine from being turned, even if the slides are properly set to unlock. r
A, in the drawing, represents the main lock-case.
Bis the outer plate of the same, containing an outward-projecting fixed cylinder, C, in which thc loose locking-cylimler D is held.
The locking-cylinder is, on the inner surface, provided with six, or more or less longitudinal slots aI a, into which Ithe slides E E are placed.
These slides are narrow steel plates, which are, by small springs l), at their inner ends, thrown out separately, so that notches c in such slides are thrown out of line of a notched plate, F, held ,immovable in the cylinder C. l
'lhe key G has a slotted tubular stem, which, when fitted upon -a central pin, H, of the cylinder D, receives the several slides in the slots, and by beingv pressed down, forces the slides inward, to bring their notches c in line with the plate F, liberating thereby the cylinder D from such plate F, and allowing the latter to be turned by the ward l of the key, which fits into a recess of the lockingcylinder. i
A spring-slide, c, travelling on the centre-pin H, under the outer arms f of the slides, throws all the slides out to an equal height, after the key is withdrawn, while the small springs b adjust the several slides separately,.and prevent their being thrown down, one by one, by buiglars4 tools, after theslide e is forced down.
The inner end of the cylinder D is closed by a plate, g, from which the pins 7i and Ii project into the lock-case.
- The innerv one of these pins h ts, when the main bolt I is locked, into a transverse notch, y, ot the same, and the outer pin h., at the same time, is tted into a recess, 7.'.at the corner ot' the bolt.
Thereby, even if the tuniblcrs should be raised on the` holt by burglars tools, the bolt will still be locked secure by such pins 7i. i, and cannot be pushed back.
When tbe locking-cyliiuler is revolved by the key, to unlock, the pin t' remains `in its notch j, while the pin h is swung around into another recess, l, of the bolt.
\Vhilc thus swung, the pin t throws the tumblers J, and slightly moves the bolt.
When the pin h is in I, the pin li leaves the notch j, and swings into a fourth notch, m, of the bolt, and at the same time the pin It in I keeps thetumblers out of the'wayfand also shifts the bolt, con'ipletely unlocking the same.
When the pin larrives in the notch m, it is, by further turning the key, brought against a lever, L, which is pivoted to the` bolt ,`and which operates the spring-latch bolt M, throwing the same open.
With the bolt may also be connected pivoted levers N N, which may be connected with upright bolts.
Upon the outer' end ofthe cylinder C is secured a small lock-case, O, which contains a simple bolt, n, that is heldin place by tuinblers p11, of the ordinary or suitable kind.
From the bolt nl projects, through slot in the lower plate Ar of the lock O, a pin, s, which, when the bolt -n is closed, tits into a recess cut into or against a shoulder or ear, t, on thc cylinder D, locking the same, so that it cannot be turned.
The ward of the key will operate the bolt n, and when the pins of the same is withdrawn from the cylinder I), the latter can be opened.
same, it is inserted into the cylinder D, to movethe slides and work 'the main bolt. The snfety of the lock is thereby considerably increased.
Having thus described my invention7 I claim as new, and desire 1.o secure by Letters Patentf it, as set forth.
