HENRY SCHMIDT, OF COLLEGE POINT, NEW YORK.

LOCK.

Application filed April 27, 1914.

To all wtom it may concern Be it known that I, HENRY SCHMIDT, a citizen of the United States. residing at College Point, in the county of Queens and State of New York, have invented certain new and useful Improvements in Locks, of which the following is a specification.

This invention coinprehends certain new and useful improvements in locks and relates more particularly to permutation locks and has for its primary object to provide a device of this character which will be of extremely simple construction and operation as well as highly-efficient in use.

Another object is to provide a device of this character which may be constructed in such manner as to be incorporated. in pill boxes and the like and formin a part of the same, by making it impossi le for unauthorized partics to open the pill box.

. Another object is to provide a device of this character which will be constructed in such manner that the receptacle with which the lock is formed, may be readily secured in closed position and the rings rotated to locked position, thereby making it very difiicult, if not impossible, for a party to open the rece tacle in the dark or even in the light, when not familiar with the combination.

A further object is to provide a device of this character which will be formed of the minimum number of parts, which will be strong and durable, and which will be constructed in such manner that should any of the parts become worn or broken, they may be readily replaced at a small cost.

lVit-h these and other objects in view as will become more apparent. as the description proceeds, the invention consists in certain novel features of construction, combination and arrangement of parts as will be hereinafter more fully described and I claimed.

For a. complete understanding of my in vention, reference is to be had to thefollowing description and accompanying draw- Spectfication of Letters Patent. Patented Feb, 2, 1915.

the line 5-5 of Fig. 2, Fig. 6 is a top plan view of the device, Fig. 7 is an elevational view of the body of the box with the cover and movable parts removed, Fig. 8 is a detail [erspective view of the U-shaped locking member, and Fig. 9 is a detail sectional view through one of the rotatable locking;

rings the body of the box of cylindrical form, the outer portion of the body being cut away, thereby reducing the thickness of the body,

except at the lower edge, the purpose of 'zo which will presentlyappear. This forms a stop shoulder 3 to limit downward movement of the lower locking ring 4.engaged around the reduced I body 2. While any number of locking rings may be employed,

I have shown three such rings, the lowermost locking ring being designated by the numeral 4, as previously mentioned, while the central ring is designated by the numeral 5, and the upper ring is designated by so the numeral 6. Each of the locking rings 4 and 5 has an inwardly directed annular flange 7 formed around its upper edge with diametrically opposite portions cut away'to form the lock openings 8, the purpose of which will presently be clearly apparent. The upper portion of the body 2 is still further reduced in diameter by cutting away the outer portion thereof, as shown at 9,

to form a stop shoulder IO-to limit downward movement of the circular flange 11 of the cover 12, the lower edge of said flange 7 resting upon the stop shoulder 10, andupon the upper edge of the upper locking -ring 6,

asfwill be readily understood by referring and taperstoward one end, thereby providing a wide leg 14 having thegtransverse locking ribs 15, and anarrow 'l'ockin leg 16 havingthe transverse locking ribs lii'ops posite the ribs 15, saidlegs 14 and 16 de te'ierrlng in detail to the drawings by 5 numerals, 1 designates the bottom, and 2,

ings, in which- Figure 1 is a side elevation of the compending through suitable openings in the .10 lete device in locked position, Fig. 2.is a cover 12. It will be understood thatgthefi ongitudinal section through the same,- F ig. locking ribs 15 and 17 are positioned upon 3 is a view similar to Fi .2 with'the rings the outer faces of the legs 14 andlfi arid in unlocked position an the top partially that the locking ribs on ,each leg are-spaced." remOved Fig. 4 is a transverse sectional from one another to correspond with the 11K 55 view taken onthe plane of line 441of. Fig. height of the'locking 4, 5 and -6. The" 2, Fig. 5 is a transverse sectional view on legs 14 arnd16'of the U-sha'ped locking mem-,

her 13 are adapted for sliding movement inthe longitudinal guide channels 18 formed in diametrically opposite portions of the body 2 as the cover 12 is placed in position or removed. It will be readily seen that the cover 2- can only be placed in position or removed when the locking rings 4 and 5 are in unlocked position with the wide-and narrow leg openings 8 opposite the guide channels 18 to allow the locking ribs 15 and 17 carried bv the legs 14- and 1G respec tively, to pass through the lock openings 8.

After the cover 12 has been placed in position upon the body .3, the locking rings 4 and 5 may be. rotated to locked position, thereby bringing the inwardly directed flange 7 of said rings to position above the locking ribs 15 and 17 and preventing re-. moval of the cover 12.

it will be understood that when it is desired to open the receptacle, it is necessary to rotate the rings 4 and 5. until the proper numerals 15) are brought to position opposite the arrows or other pointers located upon the lower enlarged portion of the brdy l and upon the ring 3 and directed toward the rotatable rings 1 and 5, the ring 6 being held stationary by a rivet 21 or other suita le means ngaged therethrongh and through tlnbm :2, after the rings 4 and 5 have been p ed in position upon the body By seem mg the upper ring (3 against movement, danger of the loch rings being withdrawn from the body 2 during an attempt to open the rece 'itacle, will be eliminated.

.Wlnle 1 have shown my invention applied to acylindrical receptacle, it will be understood that this loclc may be incorporated in various forms of receptacles and other de'vic s.

\Vhile I have shown and described the.

' site cut-away portions, :1 flange formed at the lower end of said body to limit downward movement of the said rings, a cover, a fiat Ushaped locking member having its central portion mounted in said cover and provided with depending legs engaged in said grooves, an upper stationary ring above the rotatable ring for preventing upward movement of said rotatable rings, and transverse locking ribs mounted on said legs of the U-shaped locking member for engagement beneath the flanges of said rotatable rings to prevent removal of the cover.

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

I HENRY SCHMIDT.
