BALDWIN H. KANNENBERG, OF OAK PARK, ILLINOIS, ASSIGNOR TO AMERI- CAN CAN COMPANY, OF NEW YORK,

JERSEY.

N. Y., A CORPORATION OF NEW Specification of Letters Patent.

Patented March 5, 1907.

Application filed September 27, 1905. Serial No. 280,248.

To all whomit may concern:

Be it known that I, BALDWIN H. KA NEN- BERG, a citizen of the United States, residing in Oak Park, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Slip-Cover Sheet- Metal Cans for Lard and other Articles, of which the following is a specification.

My invention relates to improvements in the construction of slip-cover sheet-metal cans of large size, such as are commonly employed for holding and shipping lard, such cans being ordinarily about twelve inches in diameter by twelve to fifteen inches in height.

Owing to the large size of the cans and to the fact that for economy and otherreasons they are necessarily constructed of light thin sheet-metal, (tinplate,) considerable difficulty is experienced in their practical use in keeping the cans in shape during handling and shipment when filled with lard or other comparatively heavy materials, as any displacement of the slip-cover leaves the upper end of the tall large-diameter can-body unsupported or braced against collapse when the can is lifted by its side handles, as the slip-cover gives little support to the upperends of the can-body unless it is held very firmly seated thereon, so that its surrounding dependent flange will engage at its extreme upper portion or base the upper end of the can-body, and heretofore great difficulty has also been experienced in keeping the slip-covers on the cans at all, so as to protect the contents from molestation and dirt during handling and shipment.

The object of my invention is to provide an improved construction of such cans whereby the difliculties heretofore experienced may be practically overcome or avoided without materially increasing the cost of manufacture, or interfering with the convenient use of the cans for both packer and consumer, or the stacking of the cans one on top of another in shipment or storage.

My invention consists in the means I employ and herein shown and described for practically accomplishing this resultthat is to say, it consists, in combination with the tall large-diameter sheet-metal can-body pro vided with side handles having curved and downwardly-inclined outer edges or rims and the slip-cover, of a slip-cover holder having depending ends furnished with hooks engaging the can-bodyhandles and extending diametrically over and across the cover and provided with horizontal bends serving to tighten the holder on the cover and by their engagement with the flat or disk portion of the cover preventing the holder, which is preferably of round wire, twisting or turning, the downwardly-inclined outer edges or rims of the handles preventing the holder-hooks from slipping thereon in either direction without increasing the tension and clamping action of the wire cover-holder on the cover.

My invention also consists in the novel construction of parts and devices and in the novel combinations of parts and devices herein shown and described.

In the accompanying drawing, forming a part of this specification, Figure l is a plan view of a lar can embodying my invention. Fig. 2 is a central vertical section 011 line 2 2 of Fig. 1, and Fig. 3 is a detail partial elevation.

In the drawing, A represents the cylindrical body of a sheet-metal lard-can, the same being preferably about twelve inches in diameter by twelve to fifteen inches in length or height.

B B are the side handles, secured to the can-body in the usual manner, the same having outwardly-curved and downwardly-inclined outer edges or rims b.

C is the lower or bottom head of the can, secured to the lower end of the can-body by a folded seam c, the head C being countersunk to form a downwardly-projecting rim 0.

D is the slip-cover, having a depending slip-cover flange d surrounding and embracing the upper end a of the can-body, which is preferably furnished with an annular bead a and annular groove a The slip-cover D preferably has a countersink d, forming a raised annular rim (1 F is the slip-cover holder, preferably of steel wire. It is provided with depending end portions f, each furnished with a hook to engage the curved and downwardly-inclined outer edges or rims b of the handles B at the middle and highest portions thereof, so that the hooks f cannot be slipped in either direction on the handles without increasing the tension and clamping effect of the wire cover-holder F on the cover D. The

ICO

wire cover-holder F has a straight portion 1 extending over the flat disk countersunk portion (1 of the slip-cover D and recesses or bends f to receive or accommodate the raised annular rim d of the cover D. The wire cover-holder F is also provided with horizontal bends f"bends in a plane parallel to the disk of the cover D and engaging the samethese horizontal tightening-bends 7 being formed in the holder F after the can has been filled and the cover D and holder F are applied thereto and serving to tighten the wire cover-holder F upon the cover and securely clamping the slip-cover on the canbody and ali'ording a somewhat laterallyextended bearing of the holder on the cover, and thus preventing any tendency of the round wire-holder to twist or turn upon itself. To remove the cover from the can, the horizontal tightening-bends f in the holder F may be straightened out with a pair of pliers or other implement, thus increasing the diametrical length of the holder, so that its hooksf may be disengaged from the rims b of the handles B. The slip-cover holder F, by reason of the countersink in the cover and bends or recesses f in the holder to receive the raised rim (1 of the cover, does not interfere with the cans being piled or stacked one on top of another, while at the same time the slip-cover is held and clamped home on the can-body very tightly and securely and with its slip-cover flange in firm engagement at the base or upper edge there of with the top edge of the can-body and with the lower edge of said cover-flange in very close engagement with the annular j bead or swell a near the upper end of the can- 1 body, thus producing a large can of great united strength and resisting power against injury or collapse in handling and shipment.

I claim 1. In a laid or other sheet-metal can of large size and diameter, the combination with the slip-cover and flexible sheet-metal can-body provided with outwardly-bowed side handles projecting downwardly at an angle to the can-body and secured thereto at their upper edges and having curved and downwardly-inclined outer edges or rims, of a wire slip-cover holder having depending ends furnished with hooks, engaging the curved and downwardly-inclined rims of the can-body handles, and having a straight portion extending over and diametrically across the cover, and provided with horizontal bends engaging the flat or disk portion of the cover and serving to tighten the holder on the cover and afford a laterally-extended bearing of the same against the cover, substantially as specified.

2. The.combination with a canbody furnished with outwardly-bowed side handles projecting downwardly at an angle to the can-body and secured thereto at their upper edges and of a slip-cover, and a wire holder extending over and across the cover and having depending ends furnished with hooks engaging the handles, said holder being provided with a tightening-bend in the plane or the cover and engaging the same, substantially as specified.
