MIOHAELIS ALEXANDER,
OF KONIT'Z, GERMANY.
CLOSURE F OR MILK OR OTHER CANS.
SPEGIFIGATION forming part of Letters Patent No. 654,044, dated July 17, 1900.
Application filed April 6, 1900.
To aZZ whom it may concern:
Beitknown that LMIOHAELIS ALEXANDER, a subject of the Emperor of Germany, residing at Konitz, Prussia, Germany, have invented certain new and useful Improvements in Closures for Milk or other Cans, of which the following is a full, clear, and exact description.
The present invention relates to closures for milk and other cans; and it consists of the details of construction hereinafter set forth, and particularly pointed out in the claims.
In order to render the present specification easily intelligible, reference is had to the accompanyin g drawings, in which similar letters of reference denote similar parts throughout the several views.
Figure 1 is a vertical section through a milkcan, showing the cover in position on the same. Fig. 2 is a similar section, drawn to a larger scale, of the cover of the can. Fig. 3 is a side elevation of a key for opening the closure, and Fig. 4 is a plan of the cover.
The upper rim of the can is flanged outwardly, as at a, and the upper face of the said flange is provided with an annular groove which is filled out with soft metal-such, for instance, as white metal or the like-as indicated at b. The cover is slightly countersunk into the can and provided with a similar flange havingadownwardly-extendingannularridge. f, adapted to fit onto the upper surface of the soft-metal ring let into the flange of the can. The said cover is further provided with an upwardly-extending annular flange in which a series of radially-movable hook-stems are guided. At the ends of these stems hooks e e are provided, which are adapted to engage under the lower conical surface of the canflange a, so that the more the said hooks are tightened against the said conical flanges under surface the more the cover will be closed onto the top of the said flange. The stems of the said hooks e pass into a circular housingf, arranged on the top of the cover and containing therein a rotary disk g, guided in suitable manner. The ends of the said stems are turned upwardly and project into eccentrically-arranged slots g in the said rotary disk. These slots are so arranged that when the cover is turned in one direction the hooks will all be actuated toward the flange a, and
Serial No. 11,851. (No model.)
the same has been turned to tighten the hooks- 6 under the flange a.
Two or more keyholes h h are provided in the cover of the housing, through which the teeth of a key, as illustrated in Fig. 3, may be inserted, so as to depress the spring icwhen it is required to turn the disk back to release the hooks e e to open the can-cover.
The device is manipulated in the following manner: The cover is placed on the can, and the disk 9 is turned by suitable means, so as to pull all the hooks e 6 toward the flange a. The spring will then engage with its upwardly-turned end one of the depressions of the cover and retain the said disk against turning back. If the cover is to be opened, the key illustrated in Fig. 3 is inserted through the openings h h of the housing f and the spring is depressed, whereupon the disk g is free to be rotated back and release the hooks e e.
The closure described has several advantages. In the first place the more the ridge of the cover sinks into the soft-metal ring provided in the can flange the more the hooks e 6 will draw the cover down onto the same, so that the closure will always be tight, and in the second place it will not be necessary to seal the cans, since the keys illustrated in Fig. 3 may be varied in a great many ways, so that it will not be possible to open any can unless the key is present.
I claim as my invention 1. The combination of a can having an upper horizontal flange and a ring of soft metal let into the same, a cover having a downwardly-extending ridge to fit onto the softmetal ring, an inclined under surface to the said can-flange and a series of horizontallymovable hooks mounted in the cover and means for pressing their free shanks against the said inclined under surface of the flange to produce a wedging action substantiallyas described. 7
2. The combination of a can having an upper horizontal flange with, a conical under surface, a cover having a downwardlyextending annular ridge, an annular ring of soft metal let into the upper surface of the said can-flange into which said ridge fits, a series of radially-extensible hooks on the said cover having their free ends adapted to grip under the conical surface of the said flange, said hooks having upwardly-turned rear ends, a rotary disk mounted in the said cover having a series of eccentrioally-arranged slots into which the ends of the said hooks fit and means for retaining, the said disk in a position in which the hooks are tightened onto the can-flange substantially as described.
3. The combination of a can havinga horizontal upper flange with an annular ring of soft metal let into the same, a cover having a downwardly-extendin g ridge to engage said soft-metal ring, a series of hooks radially guided in said cover and adapted to engage under the said can-flange, a housing on the said cover into which the shanks of the said hooks extend, a rotary disk in said housing having a, series of eccentrically arranged slots into which the upturned ends of said hook-shanks engage, a spring mounted in the bottom of said housing and having an upwardly-turned end to contact with the under surface of the said disk, a series of depressions in the under side of the said disk and openings in the said disk above the said spring to enable the same to be depressed to disengage the disk substantially as described.
In Witness whereof I have hereunto set my hand in presence of two witnesses.
