PROVISIONAL SPECIFICATION.
Improvements relating to Shaking-barrels and other Revolving
Receptacles.
I, ALBERT JOSEPH LEAVER, of 47, New Street, Erdington, in the County of
Warwick, Engineer, do hereby declare the nature of this invention to be as
follows:-
C
This invention consists of improvements relating to shaking barrels and other
revolving receptacles, my object being to provide a more convenient and effective
means for securing the detachable stave or the cover of the charging and discharging
aperture than exists with such appliances as are at present in ordinary use.
In carrying my invention into effect I construct the barrel in any convenient
manner suitably for the particular service required, mounting it upon a central
supporting shaft with or upon which it revolves. Upon each end of the detachable
stave or the cover of the aperture through which the articles are placed within or
withdrawn from the barrel, I attach one end of a slotted arm or rod. The opposite
end of each rod is pivotted upon the adjacent end piece of the barrel, the slot or
elongated aperture permitting of a sliding movement of the rod relatively to its
pivot or fulcrum. When the cover is closed on to the aperture, the slotted end
of each rod projects below or beyond the fixed pivot pin, but when the cover is
raised, the rods are drawn with it until the lower extremity of the slot is brought
into contact with the pivot pin; the cover is then turned to either side of the
aperture, the rods moving with it about their pivots, until it is brought to rest
upon an adjacent fixed part of the staving or circumferential covering.
At the upper end of the slot in each of the radius rods I form a recess or
aperture at right angles for the reception of the pivot pin when the rods are in the
closed position, and I preferably taper or incline the sides of such apertures in
order that when they are forced over the pivot pins the cover shall be drawn
tightly into its closed position. The rods are secured in this closed position
preferably by means of nuts screwed on to the projecting ends of the pivot pins.
Instead of employing fixed pivot pins with slotted radius rods as hereinbefore
described, I sometimes arrange the pivot pins to slide in grooves formed on the
barrel ends and I make other modifications to meet varying requirements.

Improvements relating to Shaking-barrels and other Revolving
Receptacles.
1, ALBERT JOSEPH LEAVER, of 47 New Street, Erdington, in the County of
Warwick, Engineer, 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 :-
This invention consists of improvements relating to shaking barrels and other

page_text: revolving receptacles, my object being to provide a more convenient and effective
means for securing the detachable stave or the cover of the charging and discharging
aperture than exists with such appliances as are at present in ordinary use.
In the accompanying sheet of explanatory drawings to be hereinafter
referred to;-
Figure 1 is an end view of a shaking barrel illustrating the application of my
invention.
Figures 2 and 3 represent in side elevation and end elevation respectively, and to
a larger scale, one of the sliding arms in combination with the detachable stave or
cover.
The same reference letters in the different views indicate the same parts.
In carrying my invention into effect I construct the barrel in any convenient
manner suitably for the particular service required, mounting it upon a central
supporting shaft A with or upon which it revolves. Upon each end of the
detachable stave or the cover B of the aperture through which the articles are
placed within or withdrawn from the barrel, I attach one end of a slotted arm or
rod as C. The opposite end of each arm or rod is pivotted upon the adjacent end
piece of the barrel, the slot or elongated aperture permitting of a sliding movement
of the rod relatively to its pivot or fulcrum. When the cover is closed on to the
aperture, the slotted end of each rod projects below or beyond the fixed pivot pin D,
but when the cover is raised, the rods are drawn with it until the lower extremity
of the slot is brought into contact with the pivot pin; the cover is then turned to
either side of the aperture, the rods moving with it about their pivots, until it is
brought to rest upon an adjacent fixed part of the staving or circumferential
covering as shown by dotted lines at Figure 1.
At the upper end of the slot in each of the radius rods I form a recess or
aperture at right angle for the reception of the pivot pin D when the rods are in
the closed position, and I preferably taper or incline the sides of such apertures in
order that when they are forced over the pivot pins the cover shall be drawn
tightly into its closed position. The rods are secured in this closed position
preferably by means of nuts screwed on to the projecting ends of the pivot pins D.
Instead of employing fixed pivot pins with slotted arms or radius rods as herein-
before described, I sometimes arrange the pivot pins to slide in grooves formed on
the barrel ends and I make other modifications to meet varying requirements.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is ;-
1. In shaking barrels and other revolving receptacles the improved means for
securing the detachable stave or the cover of the charging and discharging aperture,
substantially as described.
2. The combination with the detachable stave or cover B of a shaking barrel
or like appliance, of the sliding arms or rods C pivotted upon the barrel ends,
substantially as and for the purposes described and as illustrated.
