BARREL-LINING.

SPECIFICATION forming part of Letters Patent No. 591,455, dated October 12, 1897. Application filed March 6,1896. Serial No. 582,071. (No model.)

To all whom it may concern:

Be it known that 1, CHARLES E. COTTRELL, a citizen of the United States, residing at the city of Minneapolis, in the county ofHennepin and State of Minnesota, have invented certain new and useful Improvements in Barrel-Linings, of which the following is a full, clear, and exact specification.-

This invention relates to improvements in the art of lining barrels for holding flour and other finely com'minuted dry substances, which, if not leaky between the joints of the staves when first used, are liable to become so from the after shrinking of the staves and from the handling ofthe barrels.

Prior to my invention the common practice has been in efforts to avoid'leakage of finelycomminuted substances from a barrel toline the barrel with overlapping sheets of paper placed therein loosely and in some instances to paste a paper lining throughout the interior stave-surface of the barrel, but with loose sheets there is a leakage between the laps of the paper and considerable inconvenience and an objectionable loss of time required to place the sheets in position during the filling of the barrel, and besides, after the barrel is filled with the powdered substance there is not sufficient elasticity in the paper to resist splitting due to the contraction of the staves and the consequent separation at their joints at the very time when the leakage occurs which said sheets are intended to prevent, and all this is equally true as to paper pasted upon the staves.

Now the object of my invention is to provide a barrel-lining of such a character that it may be readily, quickly, and conveniently inserted within the barrel in its operative position and when so inserted will have no joints opposing the staves through which powdered substances may escape to the staves and which is so constructed that it may and will expand and contract with the stave-joints and thereby avoid any possibility of its cracking or splitting and will effectually prevent leakage of the powdered substances between the joints of the staves, however great may be the separation between said joints or however roughly the barrel may be handled. This object is attained by devices illustrated in the accompanying drawings, in which- Figure 1 illustrates a perspective View of a barrel with the head removed and parts broken away to show the position of my lining therein. Fig. 2 is a transverse vertical section of the barrel and lining. Fig. 3 is a side elevation of a barrel and packer arranged above the same in its operative position and having sleeved thereon abarrel-lining embodying my invention. Fig. 4 is a vertical section through a barrel and lining of my invention, showing-the ends of the lining folded over across the heads of the barrel. Fig. 5 is a top planview of the same with the head of the barrel removed, and Fig. 6 is a transversesection of my lining, showing the manner in which the-vertical edges thereof are interlocked to form a tight joint preventing the escape of powdered substances therethrough.

In carrying out my invention I take paper of any length, and preferably quite a stifi strong Manila paper, and corrugate it transversely of the roll, which corrugated paper is thus cut into suitable lengths, so that when placed within the barrel, with the corrugations thereof running lengthwise of the barrel, it shall overlap, substantially as shown in Fig. 6--that is to say, so that one or more of the corrugations along the lapping edges thereof shall be fitted one into the other and by this means form an angular joint, preventing the escape ofpowdered substances therethrough. It will be no departure from my invention, however, to coil such corrugated strip within the barrel, so as to have two or more thicknesses throughout, nor would it be a substantial departure from my invention to dispense with this lapping of the corrugations and have the two vertical edges of the lining separated from each other when the space between them is at a point removed from the joint of'a stave, as shown in Fig. 2, when by so doing leakage may be avoided 5 but in prac-' tice I prefer to have the joints lapped and locked together, as before stated and as shown in Fig. 6.

In the figures of the drawings, A indicates a flour orother barrel designedto hold finelypowdered substances, B my corrugated lining therefor, and in Fig. 3. C a packer on which the lining may be sleeved andqtogether with which the lining may be inserted in the barrel in the process of filling the same. In thus inserting the lining simultaneously within the contents of the barrel the lining is sleeved over the packer O, as described, and secured thereon in any desired manner, such as by means of a simple clamp of any wellknown or suitable construction or other means, and the barrel is then elevated, so as to pass upward over the packer and the lining, the flour or other material allowed to descend into the barrel, and the packer finally withdrawn, leaving the lining between the barrel and its contents, the corrugations in the lining permitting the latter to expand under the pressure of the flour or contents and to accurately conform to the contour of the barrel. As indicated at a in Fig. 6, the overlapping joint before referred to isshown, and at Z) the opening between the opposing edges thereof at a point between the joints of the staves before referred to.

In some instances it may be desirable to make the lining of a sufficient length greater than the barrel, so that, as indicated at c in Figs. 4 and 5, the ends of the lining may be folded over across the barrel-head-that is to say, partly across, as shown in Fig. at, or entirely across; but as the leakage of barrels containing finely-powdered substances is at the stave-joints and as such leakage may be prevented so long as the lining extends throughout the lengths of the staves-that is.to say, from head to head-it will be no departure from my invention to omit the end folds above referred to.

In practice it is preferred to have the corrugations or flutes in the lining extend lengthwise of the barrel, as shown in the drawings, but it will be no substantial departure from my invention to use any other form of indentations or folds in the paper which will give the paper sufficient elasticity to contract and expand with the contraction and expansion of the staves to a degree preventing a breaking or cracking of the lining and the consequent leakage of the barrel, but in any event the corrugations and indentations at the lapping edges of the paper when lapped as above described should be of such form that the laps will be so locked together as to form a joint tight enough and of such a character as to prevent the leakage of the powdered substances therethrough. Nor would it be any substantial departure from my invention to paste or otherwise permanently fasten the lining to the barrel, so long as such pasting or fastening permits the expansion and contraction of the lining with the contraction and expansion of the staves to a degree preventing the cracking or splitting of the lining.

By the word corrugation as used in the claims is included fiuting the paper or otherwise indenting it in any manner that will serve to give it the expansibility before referred to and permit the edges thereof to be locked together.

The lining thus described maybe composed of any suitable thin material such as Manila paper, as before mentioned, and when used as a lining for flour-barrels it is desirable to use paper tinted with some color that will contrast with the flour and thus better display and improve the appearance of the latter when the barrel is open. This is a desirable feature which will readily be appreciated by those conversant with the manufacture and sale of flour.

In some instances it is desirable to form the lining of waterproof or paraffin paper, which will protect the contents from deterioration by dampness and will be especially useful in the shipment of cement and other like substances, and may be utilized to advantage in the shipment of drugs and chemicals, which could be packed in wood and provided with this lining and thus protected from deterioration.

The usefulness of my described lining also consists not only in preventing leakage of the contents of the barrel or package, but also in protecting the contents from superfluous and other deleterious substances adhering to the inner surface of the barrel, such as charcoal resulting on the inner surface of the barrel, from the latter being scorched or charred when being heated in the process of manufacture.

My improved barrel-lining is easily inserted into the barrel and may be held in place by the simple pressure of the contents, or, if desired, may be secured by means of paste touched on a few spots at the time the barrel is being completed, or the lining may be in .serted at the time the heading is taken out preparatory to filling the barrel.

It isalso very evident that the exterior of the lining while on the packer C may be touched ata few spots throughout its surface with a small quantity of paste and when inserted into the barrel in the described manner the pressure of the contents of the barrel will cause the paste to stick the lining to the barrel, or the interior of the barrel may be provided at suitable intervals with a small amount of paste, and when the lining is inserted over the packer the same result will follow.

I am aware that it was not new prior to my invention to form barrels of corrugated metal with the corrugations running vertically or longitudinally of the barrel and stays or ribs located around the barrel in such corrugations and surrounded by hoops to impart rigidity to the metal and prevent the barrel thus constructed from being expanded out of shape, but the same is not the equivalent of my invention and I do not wish to claim the same, as my invention is materially different therefrom in that the corrugated paper which I employ as a lining is a lining pure and simple and does not constitute any rigid part of the walls of the barrel, as does the corrugated metal heretofore used for making barrels, and consequently in my invention the lining is free to expand and contract with any expansion and contraction of the barrel-staves and to automatically conform to the shape of the barrel and contents therein, while at the same time constituting an impervious envelop for the contents.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The combination with a barrel, of ayielding paper lining provided with corrugations of a character to permit said lining to expand and contract with the expansion and contraction of the barrel-staves and thereby prevent the leakage of powdered substances iherethrough, substantially as set forth.

2. The combination with a barrel, of an expansible lining provided with corrugated overlapping vertical edges interlocking at their jointure With each other, substantially as set forth.

' 3. The combination With a barrel, of a corrugated lining adapted to expand and contract with the expansion and contraction of the stave-joints,which said lining is of greater length than the barrel and is folded over the ends adjacent the heads thereof, substantially as set forth.

4. The combination with a barrel or vessel, of an expansible corrugated lining arranged therein and being composed of paraflin or waterproof paper corrugated lengthwise, substantially as set forth.
