.UUVNITED STATES OFFICE The invention relates generally to locksand it has particular relation to a, lock for bottle caps orv the like.
310116 object-of the invention is to provide an improved bottle cap which maybe so locked on a bottle that unauthorized persons normally will notbe ableto remove the cap and hence the contentsof the bottle without breaking the latter.
Another object of theinvention is to provide a bottle cap of this character which includes a simple form of combination lock. that may be readily. manipulated either to lock the cap on the bottle or to permit its removal by one possess- .ing the combination.
Another. object of the invention is to provide a bottle cap of locking character which may be manufactured in avery'eflicient and economical manner: so as :to provide a cap not prohibitive in use because ofits cost. I
. For'a better understanding of the invention means of asplit locking ring-32 which is partially disposed in the groove 2-0 in the inner shell, and
reference .may be had to the drawing illustrating oneiorm thereof, wherein:
Figure .1 is a fragmentary and elevational view of a bottle illustrating a cap constructed according to oneform ofthe invention, with the cap shown in verticalcross section. Fig. 2 is a fragmentary view as seen from the right sideof Fig. l, withparts of the. cap in cross section so as to illustrate certain details more clearly." I
Fig; 3' is a cross-sectional view taken substan tially along the line 3-3 of Fig. 1. I
Referring to Fig. 1, an ordinary bottle is indicated at l1] and is provided "with a neck H having conventional threads P2. .The bottlecap illustrated comprises an inner shell l3 having grooves M in its inner peripheral surface for receiving the threads l2 on the bottle neck, and amend wall for closing the opening in the bottle. Normal- 1y, a-layer l B of sealing material may be disposed between the end Wall l5 and the end of the bottle neck, if a more perfect seal is desired. The outer periphery of the shell I3 is slightly tapered, as
" indicated at ll, and at the upper and lower ends of the taper, shoulder portions l8 andl g may beprovided for a purpose which will later be set forth. The tapered portion of the shell also is provided with an annular groove 26 and the purpose of this groove will also be set forth hereinafter... At its upper side, the end wall 15 of the shell isprovided with a pair of radially spaced and circumferentially,extending ribs 22 and 2.3 v v I outer shell above the end wall l-5, includes a transversely extending pin 41 having a conical 55 and, asbes-t shown by Figs. .2 and 3, these ribs are not completely :annular but are separated at one point to provide a substantial space 2-4. At either side of this space, the ribs are bridged by walls 25 and 26 respectively. A single and wide rib mi-ghtbe usedin place of two ribs, but by using two ribs, the cost of the cap may be reduced. 5
The cap also includes an outer shell 28 telescopically 1'i-tting..-over the inner shell I3, which is providedwith inner shoulder portions 29 and 30 adjacent the shoulder-s l8 and IS on the inner shell, and an inner tapered portion 3| adjacent to the tapered portion IT on the inner shell. These parts ofthe shells are substantially complementary so as to properly position the outer shell on the inner shell and provide a more closely united and s-tronger assembly. is desirable partic-ularly in properly guiding the outer shell in any rotary movement thereof on and relative to the inner shell and in 1z roviding a more rigid assembly when the shells are locked together for simultaneous rotary movement.
Theshells are retained in assembled relation by .ina, groove 33 in the -outer shell. This ring is of such construction that it naturally tends to con- 25 tract into the groove 29 but the groove 33 is of such dimensions that the ring may expand thereinto sufii'ci-ently to permit inserting the inner shell into the outer :shell. The side wall of the outer shell extends substantially above the end wall 15 of the inner shell when the parts are in assembled relation, and is provided with diametrically disposed openings 34 and 35 Upwardly of theseopen-ings, the outer shell has an end wall 36 which closes it similarly to the closing 5 of the inner shell by the end wall l-5. Thus within the upwardly projecting portion of the side wall on the outer shell and between the end walls I51and 36, a substantialspace is provided which is adapted to receive a locking device to'be here- 40 'inafter, describe-d.
As shown best by Figs. 2 and 3, the upperpart .of the'upper shell has spaced projections 49, M
and 32 at each side of the diametrical line of openings 34; and 35, which define transverse spaces 43 and 44 extending substantial-lyto the rim of, the shell. The projections 48 are bridged b an upper portion 5 integral with the shell,
shown by Fig. 1, but between the pairs of projections 4i and 42, a space 46 is provided as 50 shown by Fig. 2 which is-open substantially to the upper and base portion '36 of the shell. 7
.A locking device providedin the space in the head 48 at one end and it will be noted that this head has circumferentially spaced and scribed indicia. A sleeve 49 having similar indicia is rotatably mounted on the right end of the pin 4'! and substantially abuts the head 48, and this sleeve at its left end terminates in a cam 50 which, as best shown by Fig. 2, has radially and oppositely projecting portions 5| and 52. A second sleeve 53 has a press fit on the left end of the pin for rotation therewith and foradditionally locking the sleeve to the pin, a portion of the sleeve as indicated at 54 may be pressed into a groove in the pin. Manifestly, other suitable means may be used for locking the. Sleeve 53 to the pin so that they will rotate together. The sleeve 53 is provided with acam 55 which may be identical to the cam 50 and on adjacent sides of the cams, the sleeves are provided with short and substantially abutting portions. It follows that the cams are disposed in spaced relation and that they can not move axially relative to the pin. The cams are so'shaped that when in proper vertical positions as shown by Figs. 1 and 2, and with the space 24dir'ectly below the space between projections 42, the cams-and pin may be moved transversely so as to dispose thecam 50 between the pair of projections 42 and between the end walls 25 and 26 on the inner shell. When the cam 50 is so positioned, it looks the shells so that upon turning the outer shell, the inner shell turns therewith. With the cams and pin in positions as shown in Fig. l, the outer shell may turn relative to the inner shell and by turning the pin 47 and/or loose sleeve 53, one or both cams may be so positioned that thepin and cam assembly cannot be moved to the right because one cam would engage one of the ribs 4! and 42 as the case may be. The wall 45 of course will prevent any undesirable movement'of the P assembly in the opposite direction.
It will be appreciated that it is necessary for both cams to be positioned vertically as shown and that the pin 41 and sleeve 49- be separately turned to'properly position the cams to permit transverse movement of the assembly to'lock the shells. It will also be appreciated that the arrangement is ofsuch character that normally no one would be able to see from the-outside how the camswere positioned and it would be necessary to have predetermined knowledge as to how the pin and sleeve 53 should be turned. By numbering the indicia on the sleeve 49 and on the head 48 and providing a suitable marker-on the outer shell 28 adjacent thereto as shown by Fig. 3,-and with a predetermined knowledge as to where the indicia on the sleeve 49 and head 48 should be with respect to the marker on the shell, one may readily position the cams 50 and 55 to enable their transverse movement into locking positions. In actual practice, it will probably be easier to turn sleeve 49 until the combination indicia thereof is aligned with the marker on the shell, and then turn pin 4'! until the combination indicia thereof is aligned with that on the sleeve and hence with the marker on the shell.
In manufacturing the sleeve 49, the indicia thereon may be formed by pushing the outer end of the sleeve into a tubular die member having circumferentially spaced and axially directed teeth for forming or scribing lines thereon and it is apparent that in the manufacture of numerous sleeves, without making observations as to the position of the sleeve with respect tothe tubular die, the indicia may be positioned automatically with respect to the cam in a varying number of ways so that in effect each sleeve manufactured would have its lines scribed differently, and this automatically would provide a different combination lock on each cap manufactured. Furthermore, in fastening the pin 41 to the sleeve 53, by not directing any attention to their relative turned positions, the combination may be varied automatically so as to avoid duplicates.
The construction described may be manufactured from metal or other suitable material and the parts, with possibly the exception of the pin 48,' may be manufactured by a die casting process.
After manufacturing the parts, the sleeves 49 and 53'may be disposed in the positions shown before assembling them with the pin, by tilting each sleeve and inserting it through the adjacent opening in the side wall. of the outer shell 28, andthen the pin 41 may be pushed through the sleeve 49 and then through the sleeve 53. As stated previously, the sleeve 53 will have a press fit on the pin so as to cause its rotation therewith and after the parts are assembled, metal in the end of the sleeve may be pressed into the groove in the pin. Then prior to assembly of the inner and outer shells, the cams maybe turned until they are properly positioned for movement between the projections 4| and 42, and then the position of the indiciaon the outer end of sleeve 49 and on the head 48 of the pin may be noted with respect to the marker on the outer shell. After noting such positions of the indicia with respect to the marker on the outer shell 28, the inner shell l3 may be moved into the outer shell and this causes expansion of the locking ring 32 into the groove 33, until grooves 20 and 33 become aligned, whereupon the locking ring contracts into groove 20 to hold the shells in assembled relation. As the parts are now assembled they are locked positively against separation and it is impossible for anyone to learn of the combination except by a tedious hit-and-miss process which would-be practically impossible in viewof the enormous number of combinations that would be possible. When the parts are so assembled, and with the cams 5D and 55 aligned with the spaces 43 and 44, the cams may turn and the ribs 22 and 23 are so designed that they will not interfere with this rotary movement.
.This automatically locks the pin against transverse movement and hence causes the outer shell to become rotary with respect to the inner shell. When the cams are positioned for locking the shells, they may be moved to the right so as to lock the shells together and then the cap may be mounted on the bottle. It of course will be necessary to move the cam 50 between the end walls 25 and 26 of the inner shell and, in order to properlyposition the inner and outer shells to facilitate this movement, markers at the bottom "edges'of the shells may be provided so as to inacter is verydesirable and, in view of the fact "that it may be retailed at a small cost, it may be used in various capacities where a' cap of this character would meet a public demand.
