PERMUTATlON-LOCK FOR VALISES,

SPECIFICATION forming part of Letters Patent No. 741,639, dated October 20, 1903.

A Application iled March 4, 1903. Serial No. 146,126. (Nc model.)

To all whom, it may con/cern.:

Be it known that I, NILS S. EMERT, a citizen of the United States, residing at Omaha, in the county of Douglas and State of Nebraska, have invented a new and useful Per-1 mutation-Lock for Valises, Bags, &c.-,ofwhicl1-v the following is a specification. l

The invention relates to improvements in permutation-locks for valises, bags, satchels, and the like.

The object of the present invention is to im prove the construction of permutation-locks and to provide a simple, inexpensive, and efficient one of greatstrength and durability adapted to be readily applied to a valise, bag, satchel, or the like and capable of effectually preventing the same from being surreptitiously opened and capable of being quickly operated by a person in possession of the combination.

The invention also has for its object to provide a permutation-lock of this character adapted when the tumblers are in position to permit the slide or bolt to be reciprocated to` operate as a spring-catch for holding the sides of a valise, bag, or satchel in their closed position.

, invention consists ,ink the construction and 3o.

. scribed,illustrated in the accompanying draw' ings,and particularly pointed out in the claimsv arrangement of parts hereinafter fully de-` hereto appended, it being understoodthat changes in the form, proportion, and minori details of construction vWithin the scope of the claims may be resorted to without depart' ing from the spirit or sacrificing any of the advantages of the invention.

In the drawings,-Figure 1 is a perspective view of a valise provided With a permutation- -lock constructed in accordance with this invention. Fig. 2 is a longitudinal sectional view of the lock.- Fig. 3 is ahorizontal view' on the line 3 3 of Fig. 2, the slots ofthe tumblers being in alinement lto permit the valise to be opened. Fig. 4 is a similar View, the slots of the tumblers being out of alinement. Fig. 5 is a vertical sectional view on the line 5 5 of Fig'. 2. Fig. 6 is a detail View of-one of the graduated dial buttons or knobs. Fig.-`

' 7 is a detail sectional view illustrating the manner of connecting the slotted tumblers to the graduated buttons or knobs. Fig. 8 is a detail view of one of the resilient disks or washers for preventing the tumblers from accidentally rotating.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

1 designates a channeledlock-casing con- `structed of suitable metal and designed to be Vmounted on one side of a'valise 2; but it may be applied to satchels, bags, and various other receptacles. The lock-casing, which is rec- .tangular in cross-section, is provided with parallel sides, and it forms a guide for a channeled slide or bolt 3. or bolt is rectangular in cross-section to couform tothe configuration of the lock-casing, and it is provided at one side with slots 4, adapted to register with similar slots 5 of the adjacent side or lock-casing and normally held out of register by a spring 6. The slots 5 ofthe lock-casing are adapted to receive hooks 7 of a hasp-plate 8, and the latter is mounted on one side of the valise 2, as clearly shown in Fig. 1. The hasp-plate and the lock-casing are secured to the sides or members of the metal, frame 9 of the valise, and the spring-actuated slide or bolt is adapted to beautomatically `engaged by the hooks 7 when the valise is closed, the hooks 7 being beveled, as shown, to. permitpthemv to reciprocate the slide or bolt against the action of the spring 6.

The slide or bolt is provided at its top with slots or openings 10, in which are arranged Arotary tumblers 1l, mounted on the lower face of the top of the lock-casing and provided With slots 12, adapted to be brought into register to receive projections or flanges 13 of the slide or bolt. Theprojections or anges of the slide or bolt are disposed longitudinally thereof, and when the slots of the tumblers arer arranged in alinement, as illustrated in Fig. 3 of the drawings, thebolt or slide is adapted to be reciprocated to bring the

slots

4 and 5 into register to permit the hooks of the hasp-plate to be removed from the lock-casing. i When the valise is closed, `loo The channeled slide the slots are turned out of register, as illusl trated in Fig. ft of the drawings. The solid portions ofthe tumblers are located in the path of the lugs or projections of the slide or bolt, and the latter is locked in engagement with the hooks of the hasp-plate. The projections or flanges 13 may be formed integral with the slide or bolt, or they maybe secured to the same in any desired manner.

Each slotted tongue is provided With acentral polygonal recess 14 to receive a polygonal portion 15 of a graduated dial button 0r knob 16, which is also provided with an annular bearing portion 17, fitting in an opening of the top of the lock-casing. The stem of the dial button or knob is provided with a threaded socket for the reception of ascreW 18, which passes through a perforation at the bottom of the recess of the tumbler. By this construction the tumbler is adapted to be readily removed to change the combination. The knob or button 16 is provided with a knurled or corrugated portion to enable it to be readily rotated, and it has an annular flange 19, provided with graduations and numbers, as clearly shown in Fig. 6. Any suitable characters may be employed in connection with the graduations, and a suitable point or indicator is arranged on the exterior of the lock-casing adjacent to each of the graduated buttons or knobs to cooperate with the said graduations. A centrally-arranged knob or button 2O is connected with the slide or bolt by means of a stem 21, extending through a slot 22 of the top of the lock-casing and suitably secured to the slide or bolt, as clearly shown in Fig. 2. The slide or bolt is preferably provided with a central enlargement or boss at the point where the stem of the central knob or button is attached; but the bolt or slide may be strengthened by a separate piece, as will be readily understood. The central knob or button, which may be either smooth or knurled, is adapted to be ezdily grasped to reciprocate the slide or The slide or bolt is provided at one end witha perforated flange 23,receiving aguidepin 24, on which the spring 6 is mounted, and the said spring is interposed between the perforated flange 23 and the adjacent end Wall of the lock-casing. The lock-casing is preferablyV provided with reduced extensions 25, receiving the ends of a suitable grip or handle and secured by suitable fastening devices to the valise.

The graduated buttons or knobs are adapted to be readily rotated to arrange the slots 0f the tumblers in alinement, and when the slots of the tumblers are thrown out of alinement it will be impossible for any one not knowing the combination to open the lock.

In order to prevent the tumblers from accidentally rotating, a resilient disk 26 is interposed between each of the tumblers and the top of the lock-casing, as clearly illustrated in Figs. 7 and 8 of the accompanying drawings. The resilient disk 20, which is provided with a central opening to receive the stem of the dial button or knob, is substantially concavoconvex and is flattened when applied in position. Sufficient friction is thereby created to prevent the dial button or knob from accidentally rotating.

A lock of the class described comprising a casing provided at one side with a slot or opening to receive the engaging portion of a hasp, a spring-actuated slide or bolt mounted for reciprocation in the casing, a series of tumblers arranged to engage and release the slide or bolt, graduated exteriorly-arranged operating means connected with the tumblers, and an eXteriorly-arranged knob rigid with the slide or bolt and arranged in alinement with the said operating means, substantially as described.
