LOCK.

SPECIFICATION forming part of Letters Patent No. 57 5,539, dated January 19, 1897.

Application filed January 22, 1896.

To aZZ whom it may concern:

Be it known that I, ALEXANDER JOHN WOLFF, a citizen of the United States, and a resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Locks, of which the following is a specification.

The invention relates to improvements in locks; and it consists in the novel devices and arrangements of parts hereinafter described, and particularly pointed out in the claims.

Referring to the accompanying drawings, forming a part of this application, Figure 1 is a front view of a portion of a trunk or chest provided with a lock constructed in accordance with and embodying the invention, the lid of the trunk or chest being shown partly open. Fig. 2 is a vertical section of same on the dotted line 2 2 of Fig. 1, but showing the lid or cover closed and the hasp connected with the same being within the cylindrical locking portions of the lock proper. Fig. 3 is a detached top view of the cylindrical porchest, the two cylindrical portions of the lock being shown in position to receive the hasp connected with the lid or cover. Fig. 4 is a like view of same, illustrating the hasp within the cylindrical portions of the lock and one of said portions being shown with its entering slot turned to one side of the said hasp in order that the latter may be incapable of removal; and Fig. 5 is a vertical section of the lock on the dotted line 5 5 of Fig. 2, the lid or cover being omitted from Fig. 5 and the hasp being shown in its elevated position ready to be depressed into the cylindrical portions of the look.

In the drawings, A designates the trunk or chest, and B the cover therefor, to which cover in any suitable manner is secured the hasp 0, having at its lower end the recesses D E and bar F.

The lock proper contains the central revoluble spindle G, having upon its outer end the knob or handle H and upon its inner end the washer I, .which washer prevents the said spindle from being drawn outward from the lock. Upon the outer portion of the spindle G is mounted the cylinder J, having a solid Serial No. 576,879. (No model.)

head K and entrance opening or recess L, the latter being at the inner edge of the cylinder within the thickness of the trunk or other article to which the lock may be applied. Upon the inner end of the spindle G is placed the cylinder M, having an entrancerecess N, corresponding with the recess L of the cylinder J. The inner end of the cylinder M is provided with the sleeve 0, which snugly fits the spindle G and is secured thereto bya pin P. The cylinder J is free to revolve upon the spindle G, While the cylinder M is, by means of the pin P, rigidly secured to the said spindle G and revolves with the said spindle. Upon the spindle G may be placed the sleeve Q as a means for properly spacing the cylinders J M from one another. The said cylinders J M are, as illustrated in Figs. 3 and at, separated from one another at their inner edges a sufficient distance to receive between them the stem R of the hasp G.

In order that the spindle G may not be withdrawn outward from the lock, the Washer I has been provided thereon, and in order that the cylinders J M may not be withdrawn from the aperture S, formed in the trunk to receive them, an escutcheon-plate T is provided upon the inner face of the trunk and mounted upon the sleeve 0 between the Washer I and the solid end of the cylinder M, as illustrated in Fig. 2. The plate T will be fastened by screws to the inner side of the trunk, and hence will operate to retain the lock in position without interferin g with the revoluble motion of the cylinder M. Upon the outer face of the trunk and surrounding the cylinder J will be provided the escutcheon-plate V.

Above the cylinders J M the trunk is provided with the slot WV to permit the passage downward of the hasp C, in order that the bar F, formed thereon, may pass through the re cesses L N and reach within the cylinders J M, as shown in Fig. 2.

The spindle G and cylinders J M being in position and secured Within the aperture S and the hasp 0 being in position upon the lid or cover B, the lock will be in condition for immediate use. In order that the cover B may be closed and the hasp C secured by the cylinders J M, the latter must be turned to such position that their recesses L N are in line with the cross-bar F, as illustrated in Figs. 2 and 3, and when said cylinders J M are in this position the lid B may be closed and the said cross-bar F will pass downward through the slot V and through the recesses L N to a position in near relation to the sleeve Q, whereupon by turning the spindle G the recess N of the cylinder M may be quickly turned to one side of said bar F, as illustrated in Fig. 4, whereupon the lid B will be locked in its closed position. The cylinder M may thus be used alone for locking the lid or cover B; but preferably the cylinder J will also be given a partial rotary motion, in order that its recess L may he turned to one side of the cross-bar F, and thereupon the said cylinder J will also serve to lock the cover Bin its closed position. It is apparent,therefore,that the hasp C may be secured within the lock either by turning the cylinder M or the cylinder J, or both the cylinders M and J. The cylinder M will always be turned by pressure applied to the head ll upon the spindle G, and the cylinder J will be turned by pressure applied upon its solid head K, which projects outward beyond the escutcheon-plate V.

In order that the cover B may be opened, it will be necessary that both the cylinders J M be so turned that their recesses L N are not only in line with one another, but also in line with the bar F of the hasp O, and to help the owner of the trunk in thus turning the cylinders J M, and also to form the necessary combinations for safety, I provide upon the plate V the numbered index a, and upon the solid head K the correspondingly-numbered index I), and upon the head II of the spindle G the correspondingly-numbered index c, and the numbers of the indexes b 0 will be arranged with respect to the recesses L N of the cylinders J M, so that the user of the trunk may, by turning predetermined numbers of the indexes b 0 into a predetermined relation to one another and to some predetermined number on the index a, know that thereby the recesses L N of the cylinders J M will come into alinement with one another and the bar F of the hasp O. The locks will be so made that the index-numbers for the recesses L N of one look will not correspond with the recesses L N of other locks, and hence a person knowing the proper combination for one lock would be unable by means of that combination to open a trunk having thereon a diiterent lock of the kind embodied herein. In the present instance the indexes are so arranged with respect to the recesses L N that said recesses will be uppermost and in line with one another when the numeral 9 of the index 1) is in line with the numeral 1 of the index a and the numeral 6 of the index 0, and hence when desiring to open the trunk it will be necessary to turn the cylinder J until the numeral 9 of the index I) is in line with the numeral 1 of the index a, and then turn the head I-I until the numeral 6 is in line with the said numeral of the index I). The trunk lid or cover B may be then freely opened at will, and upon the said lid or cover B being closed the locking of the same may be eitected by simply turning to the right or left either or both of the cylinders J M.

It may be readily seen that if the first lock made is capable of having its recesses L I turned upward into alinement with one another when the numerals 1, 9, and G of the respective indexes are in line with one another the second look made may be rendered incapable of being opened when said numerals on these indexes are in' alinement with one another by simply in the manufacture of the lock forming the recesses L N in line with some different set of numerals 011 said indexes. The changes may be readily made and the lock is of such a nature that it is adapted. to receive a large number of such changes.

The lock is inexpensive of manufacture and dispenses entirely with the use of a key.

The lock is particularly adapted to trunks, boxes, and like articles, but the invention is not limited to the nature of the use to which the lock may be put, nor is the invention limited to all of the details of construction presented, since these may vary with the circumstances of the use to which the lock may be \Vhat I claim as my invention, and desire to secure by Letters Patent, is
