3 Claims.

the contents of the barrel that pass through the lining. In other words, the object is to provide a metal barrel or container possessed of all the advantages of a rubber lining and free from the defects that have heretofore been inherent in such articles. Other objects of the invention will appear from the following description.

To these and other ends hereinafter stated, or appearing, the invention, generally stated, consists in a metal barrel or container having a roll at its open end, and having a rolling (in the sense of turned over or down with the effect of a roll) loose rubber lining conforming to the surface of the open end of the barrel and providing a skirt or lip hugging the outside surface and extending towards the bilge. The fit between the part of the barrel near its open end and the rolling part of the lining serves to maintain a partial vacuum between the barrel and its detached rubber lining, and also provides a vent for any gas that may be present or generated between the barrel and lining. This fit also serves to prevent the lining from falling into or out of the barrel. The invention also comprises the.

combination with a loose rubber lining of, a clamping ring overlying the turned down or rolling part of the skirt or lip of the lining, and encirclingand-clamping the barrel and provided with ears, and screw clips or hooks for holding a rubber lined cover onto the barrel and onto the rolling part of the lining.

The invention also comprises the improvements to be presently described and finally claimed.

In the following description reference will be made to the accompanying drawing forming part hereof and in which Figure 1 is an elevational view, partly in section, of a barrel embodying features of the invention.

Fig. 2 is a top or plan view'of the same.

Fig. 3 is a sectional view drawn to an enlarged scale and illustrating features of theinvention, and

Figs. 4 and 5 are similar views illustrating modifications. 5

In the drawing l is a metal barrel having a roll 2 at its open end. 3 is EHoose lining of rubher or rubberlike material, and it is a rolling linand extends towards the bilge. The rolling portion 4 of the lining is mo ded and vulcanized to unconnected faces of the lining 3 and barrel I, there may be interposed a substance or material which neutralizes any of the contents of the barrel that may leak or seep through the rubber 20 lining. For example, the lining or liner 3 may be lime in the event that the contents of the barrel be of acid character.

There is a dished metal lid or cover 6 lined l, which is attached to 25 it. The rubber 'l is shown in Fig. 3, but is omit- Nonovelty is claimed for the cover.

There are hooks 8 connected with the barrel,

The hooks 8 may be variously attached to the barrel "I. Referring to Figs. 1, 2 and 3,this is accomplished by means of 35 a clamping ring 9 having a tension bolt Ill between its ends and provided with perforated ears H through which the threaded shanks of the hooks extend and are engaged by nuts l2. The clamping ring overlies the skirt or lip 5 of the lin-' 40 ing 3 and the roll 2 of thebarrel constitutes an abutment for it. Evidently the clamping ring can be applied to any standard barrel without the use of tools other than a wrench for tightening. the bolt lo. As shown in Figs. v4 and 5, the ears ll are welded to the outside of the barrel, and in Fig. 4 they are arranged below and clear of the skirt 5 of the lining, Whereas in Fig. 5 they arearranged underneath the skirt of the lining. In Fig. 5 the hooks are constructed in the manner described in connection with Fig. 3. In Fig. 4 the hooks are pivoted to the ears and are provided with long bills l3, so that they have a of the contents of the barrel that might leak or seep through the lining. To further explain, if the lip or skirt 5 be turned up and the barrel filled with liquid, air is driven out from between the barrel and lining and then the lip or skirt is turned down. Upon removal of the liquid from the barrel, air may not reenter between the barrel and the lining, because of the sealing effect of the close adherence of the lining to the outside of the rolled lip of the container or barrel. Similarly when the skirt is turned up, gas, if any is present or trapped, between the barrel and lining. The close fit between the outside of the barrel and rolling part of the lining prevents the lining from shifting, which, if it occurred, might result in tearing the lining. Since the rubber lining is not permanently secured to any part of the barrel, it may be readily removed and inspected and, if necessary, repaired and returned or replaced by another lining.

The word barrel is used as inclusive of containers which may not be strictly barrels, and the thickness or gauge of the metal may be comparamay escape from tively thick, and such as meets the requirements of the Interstate Commerce Commission.

It will be obvious to those skilled in the art to which the invention relates that modifications may be made in details of construction and ar- 5 rangement and matters of mere form without departing from the spirit of the invention which is not limited to such matters or otherwise than the prior art and the appended claims may require.

I claim:

1. A'full open head metal .barrel having at its open end an out-turned roll integral with the wall of the barrel, and having an imperforate rollin loose rubber lining conforming to and in contact with the exterior surface of the roll and disconnected from the roll and providing below the roll a skirt detached from and in contact with and by its elasticity hugging the outside surface of the curved wall of the barrel and extending towards the bilge.

2. A metal barrel having a'full open head and a roll chime and inside and outside curved surfaces and provided with a loose imperforate rubber lining having a fold arranged over and hugging the roll chime, and the inside surface of the fold contacting with the inside and outside curved surfaces of the barrel and providing a tension fit over the chime of the barrel.

3. A metal barrel having a full open head and a chime and provided with a loose rubber lining having a fold in which the chime of the barrel is enclosed and which hugs the chime and provides a tension fit which retains the lining in place in the absence of a lid.
