A.SWOBODA. I EXPANSIBLE BARREL OOVERQ (Model!) UNITED STATES PATENT OFFICE.

ADOLPH 1 SWOBODA, or CAIRO, ILLINOIS.

EXPANSIBLE BARREL-COVER.

SIEOIFIOATION forming part of Letters Patent No. 278,670, dated May 29, 1883.

. Application filed December 22,1882. (Model) To all whom it may concern:

Be it known that I, ADOLPH SwoBoDA, of Cairo, in the county of Alexander, and in the State oflllinois, have invented certain new and useful Improvements in Expansible Barrel- Govers; and Ido hereby declareth at the following is a full, clear, and exact description thereof, reference being bad to the accompanying drawings, making a part of this specification, in which-- Figure 1 is a perspective view of my device separated from a barrel and reduced to its minimum size, and Fig. 2 is a vertical, central section of a barrel and of said head when applied thereto.

Letters of like name and kind refer to like parts in each of the figures.

. The design of my invention is to enable the contents of a barrel to be covered from the air at any point between its upper and lower ends; and to this end it consists in the construction and combination of parts, substantially as and for the purpose hereinafter shown.

In the annexed drawings, A represents a circular disk, of, wood, having such dimensions as to enableit to be readily inserted within theopen end of a barrel, B. Secured to and extending upward from the center ofsaid disk is a square tube, 0, which is provided with a square axial space that is open at its upper end and receives and contains a correspondtherein and has such length as to cause its upingly-shaped block, '1), which-is loosely fitted pelr; end to project above the upper end of said In e.-

Resting upon the upper face of the disk A are four plates, E, which have such size and dimensions as to cause them to fill the space between the edge of said disk and the tube 0. Said plates have the same shape and dimen-' sionsin plan View and are alternately provided with tongues e or grooves e, by which their ends arecaused to engage, as seen in Fig. 1. The length of such engaging ends is sufficient to enable said plates to be moved radially outward until their outer edges conform to the diameter of the largest portion of the barrel B without causing the disengagement of said ends. Each plate E is provided witha radial slot, 6, through which a screw, F, is inserted into the disk A. Such screw operating to loosely confine said parts together and as a guide to hold its plate central andto compel motion upon a radial line.

Pivoted within an opening, a, that is provid ed at each side near the upper end of the tube 0 is a lever, G, which has the curved form shown in Fig. 2 and has its upper inwardturned end, g, loosely contained within a transverse opening, d,. that is formed within the block D, while the lower end of each. lever is adapted to loosely engage with the inner edge of one of the plates E. As arranged, the

plates E may be moved radially outward by a downward pressure upon the block D, while by an upward movement of the latter said plates will be drawn inward.

In use the head, being contracted until it will pass through the upper end of the barrel, is placed upon the surface of the contents of the same and is then caused to fill the space betweenthe sides of said barrel by means of downward pressure upon the operating-block,

structed from any suitable materiahalthough wood is preferably employed for all except the pivotal bearings, guide-pins, and engaging pins. By means of the hereinbet'ore-described head articles which would beinjured by contact with air-may be safely kept in a barrel and portions removed therefrom or additions made thereto, as desired. I Having thus fully set forth the nature and merits of my invention, what I claim as new 1s- The hereinbefore'described expansible barrel-head, consisting of the disk A, tube (3,

block D, en gaging-plates E, and levers G, combined and" arranged to operate substantially as and for the purpose shown.

In testimony that I claim the foregoing I have hereunto, set my hand this 16th day of December, 1882.

ADOLPH SWOBODA.
