To all whom tjmcy concern Be it known that I, Bonner Nimaia., of'

the city, county, vand State ofvN ew York, have invented, made, and applied to use certain new and useful Improvements in Manifold Permutation-Locks, fOrwhich'Letters Patent were issued to fme on the25th day of Septemher,1838, which said Letters Patent have been surrendered, and for which-I seek a reissue in `accordance with the following 'amended' specification and claims:

My invention in the manifold permutationlock is represented in the annexed drawings, in connection with parts ordinarily attached to other locks, constitutingan arrangement and combination of tumblers and slides operating together on the bolt by the action of the key in such a manner that the slides can be transposed or set in any given position to which the key may be formed, the bit of the key being fitted with as many separate and changeable sections as there are'slides in the lock, thereby rendering it in the power of its possessor at any time before projecting the bolt to effect, and, with the aid of an auxiliary key or wrench, or their or its equivalent, to secure any necessary permutation in the lock without removing the same or any part from the door, or anypart of the lock from the lock-case. In order, therefore, to give a plain and lucid exposition of the drawings accompanying this specification,it'may be well to refer to each portionA or figure representedl thereon and state the application or design of such in their several positions, instead of resorting to mere nominal references.- In the first place, the lock is furnished with any number of permutation-tumblers, or, as in the present example, with nine, which move upon or between each other in a perpendicular line on the face or surface of the bolt, as shown at tt, Figure A, being therekept in their places by four guides, which are firmly attached to the lock-plate-two above and two below the boltdesignated by gg g g', thrnugh which thegturnblers operate vertically by the action of the key-sections. The. tumblers are continually rorced toward and stop against the stud `s when disconnected from the slides by means of the springs u, which are separately attached to each tumbler. Directly in front and in a horizontal line with the tumblers are a f corresponding numbergof slides, which are attached to the face -of the boltand-move with the bolt, being kept in their proper places there by two guides, g g, which are lirmlysecured on the face of the bolt near-the top and bottom edge ofthe saine, forming a space be. tween them and the head *of the boltfer' the slides te operate through, to rise and fall yin conjunction with the tumblers. The slides and tumblers, being of an equal thickness, v are united together before projecting the bolt by means of the narrow projections on the ends.y

of the tumblers, which fitaccurately and pass into'the grooves of the slides, as represented on the face of the bolt, disconnected from-the lock at Fig. B, tt being the tumbler and Sv the slide. In this position the slides and tumblers become, as it were, one and the same apiece, alike subject to the action of the keysections. Both are raised up asone together untilthey attain the elevation given by the key-sections, when the slides-nare secured in a stationary position for the action of the bolt. The slides are secured in any given position by means of the cramp and nut. The top of f 'the cramp is shown at 1, Fig. A, accuratelyr` fitted on the two guides g g, and alsodisconnected from the same at Fig. E, where it is represented with the screw on the back end' of the shank which passes through the aperture c, as represented in the slide S at Fig. B, and also through the bolt, which is forthe purpose of receiving the nut, as exhibited on' the back or under side of the bolt, which lies .next the plate of the lock at Fi g.D. The slides,

therefore, bein gbetween the cramp and the bolt' and nut, may be secured in any-given position by tightening the nut. The lever Z, which is also shown on the back of the bolt at Fig. D, is for the purpose of keeping the bolt from being projected when 4the slides are not se cured in some fixed position by the cramp; A permutation being always effected in the lock when the Y bolt is back gives Irise to the necessity of' securing the same until the necessary arrangements of securing the slides to some iixed position is completed. The bolt consequently can never be projected'while the cramp remains slack. The lever l, above alluded to, is secured to the bolt bythe screw e', and acts thereon, being pressed` down by the spring s, causing' it to catch on the stud o ous proportions.

by .means of their tenons entering a mortise in' 2. zoe

. of tightening the slides in some given position. The stud o.v mentioned here is firm-ly attached, tothe plate of the lock, passing through. a

groove or slot in the bolt, forming both guide and stop for the same in its passage back and forth. It is shown at '0, Fig. Byin the position in ,which it stands in the lock. The key ofthe lo'ck, being next in order, is comprised of two` v distinct parts, .the shank and the bit, carrying the movable or permutation sections. The

shank is represented on the drawings at Fig. .'D, and the bit, disconnected from the same,

at Fig. Ef. The shank and the bitarev connected together by means of a square perforation through the barrel or pin of the bit, which A1s shown at m, Fig. E', and the square on the end of the shank as seen at Fig. D. They are secured. together by means of the tip or nut,

which is screwed on theend of the shank against thel barrel or pin of thev bit,thus uniting them together, as represented at Fig. B'. l The key is designed in thisparticular for the purpose of inverting the bit on the shank, in

order that it may be used on either or both y sides of the lock when the'sections of the key are placed in an irregular position, as shown at Fig. A, the key being there represented in a complete form for use.

a bic d cfg h i' represent the sections disconnectedfrom the bits, exhibiting their vari- They are attached to the bit the same at f,Fig. E', and secured therein by a screw pressing against them, as represented by the dotted lines inthe side of the bit at a, Fig. B. Y The key may be furnished with any number'of sections, which may be shifted'or altered at pleasure, and be used in any of the dii'erent permutations or combinations which their number will admit of. A key with nine sections like that represented in the drawin gs,

is calculated to give three hundred sixty-two thousand eight hundred and eighty diierent changes or permutations. In order to show the action of th1s -lock and the 'manner of eii'ectin g a permutation in the same, I will first state that the nut fn., as seen at Fig. D, is presented in the lock through an orifice or barrel, w, on the back side of the same, as seen in the Plate No. 2, Fig. L, for the purpose of receiving the key or Wrench, whichis exhibited on Plate No. l at Fig. C', vhaving two tips on its end, which are adapted to the holes on the top of the nut, by which means the nut is slackened or made tight. I will nonr suppose'the nut to be slackened, which is always the case when the slides are to be set in any given for -witlr the key. The key is therefore inserted 'n thev key-hole of the lock and turned. as in the act of projecting the bolt, until it comes in-con tactwith one side of the mash in the same, caus is the sprin g-latch.

ing it to stop in the position as shown at Fig. C. The key in its actionto said position raises the tumblers, which ,carry the slides up with them to the different elevationslgiven by the'sections of the key-bits. The slidesbcing now arranged after the manner of the key, the wrench is inserted in the barrel or oricerepresented at w on Plate No. 2, Fig. L, until it becomes connected with the nut a, which must be turned sufficiently to cause the lever l'to rise clear of the stud o, which is signified by the nut stopping against the projection, inside ofthe end of the lever l, as before described.

The operation of raising the lever alsosecures the slides. -The nut being rmly screwed against the bolt, draws the cramp tight upon the face of the slides, thereby compress- Ying them together, in a xed', permanent po# sition. The bolt may now be projected,which, when done, carries the slides with it, causing them and the tumblers to become separate, in consequence of their projections becoming relieved from the grooves in theslides.

and stop against the stud s, Fig. A. The projections on the ends of the tumblers, passing 'close 'against the ends of the slides, `form a stay for the bolt, which cannot be returned again until the tumblers are raised upto a sufficientheight by the key-bits to bring their projections ina line of intersection with thegrooves in the slides, when the bolt may be returned again,free and unobstructed. I will now refer to a few parts, represented on the drawings, which have not been mentioned, as they are common to other locks. b, at Fig. A, c c c are three studs for receiving the cap which coniines the various parts' to the lock-plate. The cap is seen-on Plate No. 3 at R, Fig. N.

- d is an aperture vfor receiving the arbor of the pinion, which moves or carries the cross or perpendicular bolts. These bolts are seen connected with the lock at d d', Fig. N, confined in their places bythe cap L. All the rest of the parts shown being of minor importance and plainly exhibited on the drawings, and known to' all persons acquainted withthe construction of locks, renders it unnecessary to en ter further into detail. The dii'erent sections a. b c d. efg hi are secured in the bit of thel key-by passing their lower ends, or what may be called their tenons, into a m'ortise formed in the barrel of the key-bit for the purpose of receiving them, and then vpressing them together by means of the screw a, Fig. B.

In all permutation-locks which I know of as having been made prior to my invention, the tumblers wereunadeso as to be taken out and changed by hand, to correspond with the changeable sectionspf the key-bit,.and such manipulations of the tumblers are expressly disclaimedherein; but myinvention is the iirst I know of that ha-sbeen fr ted with slides, in addition to vtumblers, and he key so construoted that the key-sections, acting through the tluiblers, place the slides inthe proper Thetumblers now drop down below said groovesl position to correspond with the changeable sectionsofthe key-bit, the slides being held in the correspondin g. positions after locking, thereby leaving the slides in thelike position with the key-bit sections, and the ends of their openings abutting against the projections on the tumblers, so that the lbolt cannot be Withdrawn until the projections on the tumblers are lifted to the corresponding heights with the opening in :the slides by the proper keybit sections, thereby forming a permutationlock, the changes in which are eected by the changes ofthe keybits orsections, instead of ,such changesbeing made by hand.

v What I claim as new a'nd of my own iuvfention isy1. Theapplication of slides or their equivalents, in combination with tumblers, each so constructed that the slides shall be set through the tumblers by a key, .or any arrangement of the key-bit sections,l or the equivalents of the salne,'and then retained as set by any com'- petent means, so that on the tuinblers resuming their quiescent positions they abut. against the slides and prevent the retraction of the bolt, substantially asdescribed and shown, but independent and irrespective of .the means used to secure the slide in place.

2. The manner ot' fitting the slides with the cramp and nut so as to retain the 'slidesin the position they have been placed in by the key-bits and tumblers, as described and shown.

3. Constructing the barrel of the key-'bit in sueh a manner that it may be inverted with reference to the handle 0r shank, substantial] y in the manner and for the purposes herein described.

In witness whereof, I have hereunto set my signature this 28th dayof October, A. 1),-1851.
