SPECIFICATION forming part of Letters` Patent No."248,1'73, dated October 11, 1881.

Application nien september 19, lssx. '(Modei.)

To all 'zt-hom, it may concern y Be itknown that I, GEORGE M. HA'rHAWAY, a citizen of the United States, residing` at'New York, in the county of New .York and State of New York, have invented certain new and useful Improvements inPermutation-Locks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accom panyin gdrawings, and to letters or figures of reference marked thereon, `which form a part of this specification. v l

My invention relates to a new and useful improvement in permutation-locks adapted for service upon trunks, closets, desks, and the like; and the novelty consists, essentially, inthe construction and arrangement of parts, as will be more fully hereinafter set forth, and

- specifically pointed out in the claims.

1n this class of devices simplicity ot' construction, a minimum liability to get ont of order, efficiency in service, and reliability and compactness are of 'greatimportance To enable others to make and use my invention, I will now proceed to describe its construction and operation, reference being hadf at right angles with the Vplane of the face, a

sleeve, a3. Around this sleeve loosely operates a disk, B, having a tangential arm, B', at the outer end of which -is the bolt B2. having a beveled surface. These parts B B B2 are formed in one piece, the bolt B2 operating within the guide a.

Pivoted upon the arm B', at c, is a lock-pawl,

C, having a hook, c', and a bearing, c?, for one. 5o

arm of a spring, C', which is properly secured tolugs` or projections cr* upon the face-plate. The hook portion c is adapted to engage in the recesses d in interchangeable combination- Yd isks D, which maybe two or more in number, and operateloosely, butsnugly, aroundt he sleeve c when the said recesses d are oppositel each other. These recesses have abrupt sides, and the lock-paw] can only be released therefrom as it is forced out by the operating-disk, 6o

which will hereinafter be described.

'.Each of the disks D has, at equal annular linesl from the peripheries, pins d.' vdriven entirely through the disk and projecting upon each side-and differentially arranged with regard to the locking-recess d upon each disk. For instance, taking the recess as a basis and turning toward the left, the pins upon one disk may be placed at one-seventh of the circuitiference, and upon another disk at one-eighth, 7o and so on, care being taken not to place the pins opposite from the recesses d. By this construction the disks may be reversed or interchanged at will, and each change of position or location will change the combination. `75, As shown and described, there are but two ot' the disks D; but it is levident that more may be used if desired, or as many as the sleeve a3 will hold. These disks D must be held into a desired set position byfriction, and to this end 8o I provide a series of friction spring-lingers, e c, extending from a body, E, and formed ot' one piece of metal, the body being clamped tightly within a slot, c',- in a -split projection or lug, E', upon the arm B.

It is important, where springs are formed of very thin spring-steel, to avoid unnecessary friction, which friction tends to weaken the spring, and, in delicate complications, to destroy the efficacy of the parts. To avoid this 9o I construct and arrange the parts specified in such a manner relatively to each other that all manipulations of the bolt when the combination is on serves to move knob-shank,bolt, pawlrdisks, and the lingered spring together, V9 5 Vand the only friction between the parts is con-4 lined to a very limited space between the pawl G and spring C; hence the advantage of securing the fingered spring E c to the bolt-arm B.

H indicates` the operating-disk, and itis provided with a recess, I1, having one abrupt side and an incline, h', ruiming from the bottom of the recess to the periphery. Ata uniform distance from the common center of this disk is secured a circle of pinsJt, of any desired number, of sufficient distance apart to admit be tween each pair of pins a spring-arm, I, having an open slot, i, which, when in position, embraces a slotted rectangular port-ion, t', of the knob-shank, and it may be readily changed t0 any position at will by springing the arm over the pins h2, each change forming a separate combination.

Kindicates the knob-shank; Ii', the outer disk,havingthc peripheral figures; and K2, the knob.

L indicates the hasp-body, having bearings l of semi-cylindrical form, to receive thejournals m of the hasp-tongue IWI, at the free end of which is the hnsp-staple m. Iligidly secured to the hasp-body L, at o,is a Hat spring, 0, the free end o of which bears against the back surface of the tongue, to throw it out of the slot a in the faceplate A as soon as the. lock-bolt releases the staple m.

Instead of having the series of pins upon the Operatingdisk, I may form a series of holes and place a single pin upon the spring-arm. It will be noticed that by placing the frictionsprings upon the arm B the disks, bolt, &c., all move together, avoiding wear, which would result if the springs were xed to the plate.

The operation of myinvention is as follows: The knob-shank is passed through the proper aperture in the face-plate until the sleeve a3 is projected through to its greatest extent and the figured disk lies close to the face. The` combination-disks are then put in place and the friction-springs brought into action, after which the operating-disk is secured upon the shank, and the spring-arm made to engage the rectangular end. As thus placed, by turning the armin onedirection the pin upon the back or under side engages the pin upon the second disk. The opposite pin upon that disk engages the'next, and so on until the last disk is engaged and the recess d therein brought in conjunction with the hook on the lock-pawl. Then reverse the revolution ofthe knob until, by a similar train of action, the next disk is brought into a similar relation, the springs upon the arm B' holding each one by friction as soon as it is in position. Then the last or operating disk is forced into position the lockpawl springs into position and the bolt may be withdrawn.

It will be seen that the changes inthe combination are almost innumerable.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. 'Ihe spring-arm I, having rectangular open slot i, combined with the knob-shank having rectangular slotted portion i', and with the-operating-disk H, having pins h2, said arm serving the several functions of holding the entire series of disks in place, of changing the combinations by being sprung over and be tween the pins h2, and of being the operating means for manipulating the series of disks, as and for the purposes specified.

2. The combination ofthe disks D d d and friction-springs, the o1)eratingdisk H, having annular pins h2, the spring-arm I, the spring lock-pawl (l, and lock-bolt B, all adapted to serve as and for the purposes set forth.

3. The disk B, arm B', and bolt B2 made in one piece, in combination with the lock-pawl C, pivoted upon said arm, and the spring adapted to hold the lock-bolt in position, and also hold the springlock-pawl into constant contact with the disks, as specified.

4.-. The spring-body E, having spring-fingers c e formed of one piece of metal, said body being clamped or held within a slot, e', in a lug, E', formed upon the bolt-arm B', in combination with disks I) D, pawl C, and compound spring Cf, whereby the disks, bolt-arm, and pawl will move together when the bolt is retracted, as herein specitied.

In testimony whereof I affix my signature in presence of two witnesses.
