G. W. DANVA, OF RACINE, WISCONSIN.
Letters Patent No. 86,005, dated .Taima/ry 19, 1869.
IMPROVEMENT IINl FERMUTATION-LOCKS.
To all whom .it may conca-n:
Be it known that I, G'. W. DANA, of Racine, inthe county of Racine, and State of Wisconsin, have invented a new and improved BurglaryProof Lock; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had tothe accompanying drawings, forming partV of this specification.
This invention relates to a new and burglar-proof lock, and is an improvement o n a lock for which Letters Patent were granted to me, bearing date December 27, 1859.
The present invention consists in certain appliances, hereinafter fully shown and described, whereby the lock is rendered more secure or invulnerable against picking than heretofore, and also less susceptible of injury in an effort to pick or to open it by force.
In lthe accompanying sheet of drawings-' Figure 1, Sheet-No. 1, is a section of my invention, taken in the line x x, iig. 2.
l Figure 3, a view of the rear side of the lock-case.
Figure 4, a detached side view of one of the spindlecaps pertaining to the same.
Figure 5, a face `or end view of iig. 4.
VFigure 6, Sheet No. 2', a face view of the socketplate of the lock.
Figure 7, an linner side'view ofthe front plate of the lock-case.l Figure 8, an outer side view of the ont plate of the lock.
Figure 9, a detached View of the key for turning the spindles of the look.
Similar letters of reference indicate corresponding parts.
A represents the case of the lock, which is of rectangular form, and has fitted within it two slide-bolts, B O, which are operated respectively by wheels D E, the latter being provided, at their peripheries, with semicircular recesses, a, ,to receive correspondingshaped teeth, b', on the wheels D E.
The bolts are moved, and the lock consequentlyf locked and unlocked, by turning these Wheels, as will be fully understood by referring to fg. 1.
F represents a series of spindles, which pass transversely through the lock-case A, said 4vspindles being placed in such a position as to form a portion of a circle,'and at distances apart corresponding to the distances between the recesses a| of the wheel D, onehalf of the diameter of the spindles extending within the periphery of the wheel D.
These spindles are notched out,*as shown at b, so that when said notches are all adjusted to face4 the wheel D, the latter may be turned'and the boltB moved, but when the solid or uncut opposite sides of the spindles are within the recesses a of wheel D, the
latter cannot be turned, and consequently the lock not arrangement, semiciroular recesses'being made in one edge of said bolt, and a series of notched spindles, G, arranged in line with the recesses. y This arrangement of spindles, and mode of operating the bolts, are precisely the same as shown in my previously-patented lock, and therefore do not require a more extended description. V
On the 'arbor H of the wheel D there is placed, loosely, a wheel, I, similar to Wheel D, it being provided with the samesemicircular notches, e. p
The wheel I is cnnected, by two pins d d, with an arm, J which projects from -a hub, K, on an'arbor, L, the latter passing through the lock-case. g
This hub K also has another arm,M, projecting from. it, which is connected, by two1pins e e, with a slide-bar, N, the latter,'when the lock is in a locked state, having its endsj f behind thebolts B O, to prevent the latter bein' referring to iig. 1. v On the bolt C there is a sliding plate, O, having semicircular recesses, g, in its edge which is opposite the spindles G, and this plate is connected, by two pins e e', with an arm, M', which also extends from the hub K of arbor L.
In order to unlock. the lock, two things are necessary to be done: rst, to move the slide-barN so that its ends ff will be out of line with the bolts B C; and second, to turn the Wheels D E, in order to slide or shove the bolts back; and in order to effect these results, the spindles F G require to be turned so that the notches b of lthe spindle F will face the wheels D I,
land the notches of the spindles G made to face'the bolt C and sliding plate O.
This being accomplished, the arbor L is allowed to turn, and the arm M to move the slide-bar N.
By this arrangement the position of the notches in the 'spindles cannot be ascertained `by exerting a pressure on the bolts, as the latter, when the lock is locked, are rendered immovable by the slide-bar N, and the wheels D E cannot be turned so as to press against the spindles.
As a further safeguard, I employ the following means On the rear end ofthe arbor H of the wheel D, and at the outer side of the back plate of the lock-case, a wheel, Q, is placed loosely.
This wheel is constructed with semicircular recesses,
i, in its periphery, like the wheels D E, as shown clearly in iig. 3, and the rear ends of the spindles F are halved out, so that their flat sides, when the lock is in a locked state, will be directly opposite the spaces between the recesses z', the wheel Q, being retained in this position by a spiral spring, R, which is attached to it.
S is a dog, one end of which is connected, by two g thrown back, as will be fully understood by Thevwheel Q prevents the spindles F being turned when the spaces between its recesses t' are opposite the at'surfacesof the spindles, andlconsequently the positiondof the notches b in the spindles cannot be ascertaine In order to admit of the spindlesvlbeing' turned,v
in order to unlock the lock legitimately, the spindle G isturnedfso'that the caml will actuate the lever U, and the latter turn the wheel Q, so as to bring the recesses@ in line with the spindles F, and: i'n thus turning the Wheel Q, the dog S is thrown in connection with the ratchet T, and the arbor L and slide-bar N cannot then be turned; hence, when the spindles F can be turned, the slide-bar N cannot be moved, nor the bolts B O acted. upon or pressed back, and the lock is therefore' rendered unpickable, or burglar-proof.
In order .to prevent the spindles F G' being inj ured by force, I have each provided with a cap, V, the inner ends o f which are in against metallic boxes, W, in
. a socket-plate, X, (see iig. 2,) the outer ends of the caps being notched, toreceive the bits m ofthe `key Y.
These caps. are fitted loosely on the spindles, .but are connected therewith byplates Z, which are fitted on squares 'on the spindles, and are provided with projections or ribs, a, to fit into grooves, o, inthe inner ends of the caps. A
Ais a circular plate,.tted loosely on the arbor H of thewheel D, at the outer side ofthe front plate of the lock.'v Y
This plate has a circular hole, p, made in it, and said plate covers the outer ends of the caps V.
By vturning this 'plate the caps V can be consecutively exposed, and the spindles properly ladjusted in unlockingv andlockingvthe lock.
state.
The plate A concealsthe'ends of the caps, prevent` ing them being seen when lthe 'lock is in an unlocked This circular Aplate A' 'is fastened, Whenthe lock is unlocked, as follows:
.On the arbor H there is a hub or boss, B', having a spiral groove, r, made in it, to operate a lever, 0', and
throw a pin-(projection, at the outer end of said lever,
into the rearside of plate A.
In throwing -out the bolt B, the plate A' is unlocked,
and it is locked by lever C', as said bolt is thrown back.'- I would remark that the caps V are lettered, as also the key, and the hole p in plate A; and also the hole in the front plate of the lock, in which the caps V of the spindles G are tted, are numbered, to serve as guides in adjusting the spindles.
The 'ont plate of the lock, around plate A', is also numbered, to serve as a guide in adjusting or turning said plate;
I claim as new, and desire tosecure by Letters Patent-'- 1. The pme o, fitted en the boit o,- and provided' with the semicircular recesses, and connected with the slide-bar N, as shownand described, when said parts are used' in connection or combination with the wheels I and D, bolts B C, and the notched spindles F G, all arranged to operate in the manner substantially as and for the purpose 'set forth.
2. The wheel Q, on the arbor E of wheel D, provided withthe semicircular recesses. fi, and having the spring 'It connected with it, in combination with the dog S, ratchet T on arbor L, lever U, and the cam l en the spindle Gf', all arranged to operate in connection with the spindles F and slideebar N, substantially as set' forth. f.
3. The circular plate Af, providedwith the opening, p, in combination with the grooved hub B on the arbor H, and lever G', to serve as a lock for said plate, all arranged substantially as shown and'described.
