Improvements in Barrel or Box Closing Devices.
I, CLARENCE WEBSTER MOORE, of Peabody, in the County of Essex and
State of Massachusetts, one of the United States of America, Inventor, do
hereby declare the nature of this invention and in what manner the same is to
be performed to be particularly described and ascertained in and by the following
statement:--
Reference being had to the annexed drawings where
Fig. 1 represents a top plan view of the box or barrel showing the lever in
position on the cover for attaching and detaching the latter relative to the box or
barrel.
Fig. 2 represents a longitudinal section of the upper end of the box or barrel on
the line XX shown in Fig. 1; and
Fig. 3 represents a side elevation as seen from Yin Fig. 2.
Similar letters refer to similar parts wherever they occur on the different parts
of the drawings.
A represents a cylindrical box or barrel as usual of which only a portion, namely,
the upper end is shown in the drawings; B is the cover having on its under side an
annular projection b adapted to fit within the upper end of the barrel or box A as
shown in Fig. 2; C is an elastic packing ring preferably made of india rubber or
similar yielding material, said ring being arranged outside of the annular pro-
jection 6 and adapted to fit against the end of the box or barrel when the cover is
closed upon it as shown in the drawing.
To the periphery of the box or barrel are secured two or more helical or inclined
ribs or projections a, a.
To the central portion of the cover B is secured the screw bolt D on the upper
portion of which is preferably pivoted the clamping bar or bail E having pivoted
to its lower ends at e, e the rockers or bearing blocks E', E' adapted to fit against
the inclines a, a, when the cover is closed on the box or barrel as shown in the
drawings.
The upper end of the bolt D is screw threaded and provided with a nut & which
when tightened serves for the purpose of securing the bail and cover together and
thus preventing the accidental unlocking of the bail and its bearing blocks from
the inclines on the box or barrel during transportation or otherwise as the case
may be.
For the purpose of turning the bail E on its pivot in attaching or detaching the
cover, I prefer to use a detachable lever F adapted to be inserted in a socket E"
ou the bail E as shown in the drawings. The outer end of the lever F constitutes
a key for the purpose of turning the nut d, and said key may be made of
any well known form according to the shape or construction of the nut that
is used.
The bail E is preferably pivoted on the cover B but this is not essential as
it may be secured to said cover without departing from the essence of my
invention.
By having the blocks E', E' pivoted as above described they are capable of
automatic adjustment relative to the inclines a, a as the cover is being turned
relative to the box or barrel during the closing operation.
If the cover is in a closed position on the barrel or box as shown in the drawings
and it is desired to open the barrel or box, I loosen the nut d and turn the
bail E in the direction of the arrow shown in Fig. 1 until the blocks E', E' pass
by the inclines a, a, after which the cover can be raised and detached from the
upper end of the barrel.

page_text: In closing the box or barrel the cover, is placed in position as shown in Fig. 2,
and the bail is turned by means of the lever F until the blocks E', E', are
brought firmly in contact with, the underside of the inclines a, a, on the barrel or
box causing the cover to be forced and held air-tight against the end of the barrel
or box and the elastic packing ring interposed betiveen said parts as shown in the
drawings.
The nut is then tightened so as to prevent the accidental.,unlocking of the
cover as herein above set forth.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I. declare that. what I
claim is:
1. In a barrel or box closing device, à removable cover and a bail pivoted to
it, combined with pivoted pressure blocks on said bail, stationary inclines on the
barrel and a locking nut on the bail pivot bolt, substantially as and for the
purpose set forth.
2. In a barrel or box closing device, a removable cover and a bail pivoted to
it and having a socket for receiving a detachable lever combined with pressure
blocks pivoted to said bail, stationary inclines on the barrel and a locking nut
on the bail pivot bolt, substantially as and for the purpose set forth.
3. In a barrel or box closing device, a removable cover having secured to it,
hangers with blocks pivoted thereto combined with inclines secured to the barrel
or box and an elastic packing ring interposed between the said cover and barrel
or box, substantially as and for the purpose set forth.
4. In a barrel or box closing device, a removable cover having hangers secured
to it with blocks pivoted thereto combined with inclines secured to the barrel or
box, substantially as and for the purpose set forth.
5. In a barrel or box closing device, a removable cover having an aunular.lip on
its underside adapted to fit inside of the barrel or box an elastic packing ring
surrounding said annular lip, and hangers secured to said cover, blocks pivoted to
said hangers and inclines secured to the barrel or box all combined and arranged
substantially as and for the purpose set forth.
