SHEET-METAL SLIP-COVER CAN FOR LARD AND OTHER ARTICLES.

Specification of Letters Patent.

Patented Feb. 12, 1907.

Application filed March 31,1906. Serial No. 309,050.

To (62/ ZUILOTII/ it may concern:

Be it known that I, JOSEPH DISTER, a citizen of the United States, residing in Hamilton, in the county of Butler and State of Ohio, have invented a new and useful Improvement in Sheet-Metal Slip-Cover 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 and other articles, one customary size of such cans being about twelve inches in diameter by something like twelve to fifteen inches in height.

Owing to the large size of the cans and to the fact that for economy and other reasons they are necessarily constructed of light thin sheet metal, (tin-plate) 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 upper end of the can-body unless it is held very firmly seated thereon, so that its surrounding depending flange will engage at its extreme upper portion or base at the upper end of the can-body, and heretofore great difficulty has also been experienced in keeping the slipcovers on the cans at all, so as to protect the contents from molestation and dirt during handling and shipment unless the cans are inclosed in separate crates or jackets, which involves great additional expense and adds to the weight and freight charges.

The object of my invention is to providean improved construction of such cans, whereby the difficulties heretofore experience d may be practically overcome or avoid ed without materially increasing the cost of manufacture or interfering with the convenient use of the cans for both packer and consumer or the striking 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 object or result.

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 drawings, forming a part of this specification, Figure 1 is a plan view of the lard-can embodying my invention. Fig. 2 is a side elevation. Fig. 3 is a central vertical section on line 3 3 of Fig. 1, showing the cover on the can with the outer member of one of the sheet-metal holders sprung outward in position for applying or removing the cover and showing the other holder with its outer member in its inward position. Fig. 4 is a perspective view of one of the holders, showing the lips on the inner members of the slitted holder in the form manufactured for application of the can body and before these lips are bent under or around the roll or shoulder at the upper end of the can-body.

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

B is the bottom head, O the side handles, and D the cover.

The body A has at its upper end an annular roll or shoulder a, the same being preferably on the inside of the body. The roll or shoulder a, may embrace a wire a, if desired.

The cover D has the customary deep slipcover flange d and is also furnished with an annular peripheral raised rim, bead, or shoulder 61, surrounding an annular channel or groove 1 The inner shoulder d of the raised rim (1 is preferably somewhat sharp or approximating a right angle.

F is my one-piece slitted sheet-metal slip- 9 cover holder, the same being made preferably of heavy tin-pl ate or other somewhat springy or resilient sheet metal. The piece of sheet metal from which the holder F is made is preferably about an inch and a half in width and in height somewhat exceeds the width of the flange of the cover. The holder F is furnished, preferably, with two vertical slots f, extending in depth slightly in excess of the width of the can-cover flange. These upright slots f divide the holder into two inner members f and a central outer member the outer member f being bent outward slightlyat its base, so that the flange d of the cover may {it between the inner members f and the outer member f of the holder F. The two inner members f of the holder are each provided at its upper end with a curved lip or flange f which is applied to and bent around the annular shoulder a at the upper end of the can-body, thus securely fixing the holder on the can-body. The outer member 1 2 of the holder F has at its upper end a flange or hook f adapted to fit over and en gage the annular raised rim or bead d at the periphery of the cover D. Each of the hooks or flanges f 4 is also preferably provided with a depending flange f which snaps over and engages the inner flange or shoulder (Z of the raised rim or bead d of the cover, and thus securely locks the spring sheet-metal holder F on the cover. The central outer member f of the slit sheet-metal spring-holder F is adapted to be bent or sprung outward to permit the cover to be removed, and this outer member f also on being sprung or pushed inward thus also by its spring action enables the depending flangef of its hook f 4 to snap over the raised rim or bead d on the top of the cover at the periphery thereof. I prefer to apply two or more of the holders F to the can body and cover. Two will suffice to hold the cover in place, although I prefer to use four, as indicated in the drawings.

By this means slip covers may be secured on lard-cans or other cans of large size very securely and conveniently and without materially adding to the cost of the cans, as my slip-cover holders may be manufactured very cheaply and out of small or scrap pieces of tin-plate having little value.

I claim- 1. In a lard or other sheet-metal can, of large size, the combination with the canbody, provided at its upper end with an annul ar rim or shoulder on the inside thereof, of a slip-cover therefor having a depending flange and provided with a raised rim or bead on its top at the periphery thereof, of a plurality of single-piece slitted sheet-metal slipcover holders, each having inner and outer members fitting astride the flanges of the cover and separated from each other by a slit in the single piece of sheet metal of which the holder is formed, the inner member being provided with a flange engaging and secured to the annular shgulder on the can-b0 dy, and the outer member having a hook or flange engaging said rim or bead on the top of the cover, substantially as specified.

2. In a lard or other sheet-metal can of large size, the combination with the canbody, provided at its upper end with an annular rim or shoulder on the inside thereof, of a slip-cover therefor having a depending flange and provided with a raised rim or bead on its top at the periphery thereof, of aplurality'of single-piece slitted sheet-metal slipcover holders, each having inner and outer members fitting astride the flanges of the cover and separated from each other by a slit in the single piece of sheet metal of which the holder is formed, the inner member being provided with a flange engaging and secured to the annular shoulder on the can-ho dy, and the outer memberhaving a hook or flange engaging said rim or bead on the top of the cover, said hook or flange on the outer member having a terminal depending flange, substantially as specified.
