COMPARTMENT CAN May 6, 1930.

Filed May 16. 192

Patented May 6, 1930 UNITED STATES PATENT OFFICE JOHN M. HOTHERSALL, OF BROOKLYN, NEW YORK, ASSIGNOR 'ro AMERICAN CAN COMPANY, OF YORK, N. Y., A CORPORATION OF NEW JERSEY COMPARTMENT CAN Applieation filed May 16,

products which, for various reasons, are not mixed until they are used; Anexample of such products is a bronzing paint which comprises a heavy bronzing pigment and a carrying liquid which cannot well be packaged as a mixture before it is ready for use, as the heavy pigment will separate and settle at the bottom of the container, forming a hard cake which cannot easily be remixed with the carrier fluid.

The present type of compartment can comprises a two-part container, which includes a clamping disc insertable between two containers to be connected into a unitary package and having bendable clamping segments for separately engaging over the seamed ends of the containers so that either one may be removed from or applied to the clamping disc independently of the other container. Thus it is possible to make the separate containers in different plantsand to assemble them into a unitary package by means of the improved clamping disc of this invention.

A principal object of the invention is the provision of improved fastening means for compartment cans. a

A- further object of. the invention is th provision of a simple clamping disc with bendable segments by means of which two containers may be secured together to form a unitary. structure easily separable to afford access to either container.

A further important object of the invention is in the provision of a clamping disc for compartment cans, in which the central portion is stamped out for making smaller covers and the like therefrom and to form an opening into which a tool or instrument is inserted for prying off a disc from a can-cover to which it clings.

Numerous other objects of the invention will be apparent as it is better understood from the following description, which, taken in connection with the accompanying draw- 1927. Serial No. 191,706.

iiigs, discloses a preferred embodiment there- 0 In the drawing: Figure 1 is a perspective of a compartment can embodying this invention; 7 Figs. 2 and 3 are perspectives of upper and lower container elementsof the compartment can of Fig. 1; 7

gig. 4 is a perspective of the clamping disc; an

Fig. 5 is a section of the clamping disc in position between the adjacent ends of two container elements.

Referring now more particularly to thedrawing, upper and lower containers 10 and 11 are separately illustrated in Figs. 2 and 3 as comprising can bodies of similar crosssection having tops 12 and bottoms 13 seamed to the bodies thereof in a wellknown manner, the seams preferably projecting from or extending slightly beyond the body of the container.

In assembling a pair of such containers into a unitary structure (as shown in Fig. 1), a clamping device comprising a disc 14, preferably formed of thin sheet metal, is interposed between the endsof containers which are'to be assembled, the disc being provided with means for separately engaging the adjacent ends of the assembled containers.

As shown more clearly in Fig. 4, this disc 14 is radially cut or intersected about its periphery to form clamping segments 15 which are bendable oppositely from the plane of the disc to form alternate clamping por tions engageable over the top and "bottom seams of the container elements contacting therewith.

It will be seen more clearly in Figs. 1 and 5 that the extremities of the edges of the segments 15 extend slightly beyond the seams 12 and 13 to form a turned-up edge 16, which is more easily engageable in bending the clamping segments outwardly for removing one of the containers therefrom, a sharp tool or instrument being commonly inserted between the bent edge 16 and the body of the adjacent eontainer to pry the segment outover which-it is bent.

i The segments of the disc are first applied to" The interior of the clamping disc is formed with a large perforation 17 so that the disc removed therefrom may beused as a recovery blank from which smaller covers, caps and the like may be formed. This opening also serves as a means for engagement of a tool or instrument for prying the disc from a container cover to which it clings after one of the containers has been removed.

With this construction, it is obvious that the upper and lower container elements need not be of exactly the same size in order to be I clampingly engaged by the segments of the clamping disc, although it is preferable that the containers are of the same size in order that they maypresent a neat and unitary appearance, and that they may be evenly engaged by the opposite clamping segments 15.

one end of a container, either the top or the bottom, by bending the segments over the corresponding end seam, and thereafter the opposite end of the other container is applied to the opposite extending clamping segments of the disc in the same manner. For

any given .size of containers the segments may be bent alternately in opposite. directions (as shown in Fig. 4), but if desired the segments may be formed and left in the plane of the remainder of the disc 14. until it is applied to a pair of conta'ners. This feature of the invention is important for shipping and storing the clamping discs and also for the reason that additional mechanism and work need not be performed uponthe disc to bend the segments oppositely from Y the plane of the disc, as shown in Fig. 4.

' of its attendant advantages will be understood from the foregoing description, and

' it will be apparent that many changes may be made in the form, construction and arrangement of the parts without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.

I claim:

1. A compartment can, comprising two independently closed containers and means interposed between them engaging exteriorly adjacent portions of both of the containers to secure them together.

2. A compartment can, comprising two'independently closed containers and having adjacent end seams, forming part of the closure of each container, and means interposed between the containers adapted to engage exteriorly the adjacent end seams of both of the containers for securing the containers together in end to end position.

3. A compartment can, comprising two containers adapted for end, to end engagement, and means interposed between the containers having projecting clamping portions for engaging the bottom ofone container and the top of the other to secure the containers together in a unitary package.

4;. A combination can, comprising upper and lower containers, said containers havmg' seamed ends, and retaining means comprising adisc interposed between the containers and projecting beyond the sides thereof with portions to engage the bottom seam of one container and the top seam of the. other, to secure the containers together in a unitary package.

5. A compartment can, comprising separate containers, and a disc interposed between the containers having marginal portions projecting beyond the containers and adapted to be bent in clamping engagement with the bottom of one container and with the top of the-other container for securing the containers together in end to end position.

' 6. A clamping disc for compartment cans having separate tongues to project beyond the edges of the cans and bendable in either direction to engage over the end of a can above or below the disc.

7. A clamping disc for compartment cans adapted to be inserted between two cans in end to end position, and the disc having a slotted flange extending beyond the end seams of a pair of cans in contact therewith, the slots in the flange forming clamping fingers bendable in either direction to engage over the seam of a can above or below it.

8. A clamping disc for compartment cans, comprising a slotted edge to extend beyond the cans to be connected, the slots forming fingers which are bendable alternately to engage over the end seams of cans above andv elow the discs.'

9. In a clamping disc for insertion be- I tween compartment cans, a perforated central portion, and a radially slotted outer'margin, the latter forming clamping portions bendable alternatelyin opposite directions to engage can ends above and below the disc.

10. A compartment can, comprising two containers having adjacent end seams, one placed upon top of the other, and clamping means for separately engaging the end seam of adjacent containers so that either container can be removed independently from the other container and said clamping means.

11. A compartment can, comprising two containers adapted for end to end engagement, and a clamping disc insertable between the containers and having segments bendable oppositely into and out of separate clamping engagement, over the adjacent ends of the containers, whereby either container may be independently removed from the other container and the clamping disc.

12. A compartment can, comprising two containers having projecting end seams and aclamping disc insertable therebetween having a perforated central portion and a slotted outer margin to form segments which project beyond the end seams, bendable alternately in opposite directions for separate clamping engagement over the lower seam of one container and the upper seam of the other, the segments being disengageable for separately removing one container from the disc and the other container.

13. A compartment can, comprising containers of substantially the same cross-section and a clamping disc interposed between them having a radially cut flange projecting beyond the ends of the containers and forming bendable clamping segments for engagement alternately over the end beads of the containers, the edges of the segments being turned outwardly after clamping engagement with the end seams to provide means for the engagement of a. tool in disengaging the segments from clamping engagement with the end seam.
