PROVISIONAL SPECIFICATION left by the said John Stubbs, William
Stubbs, and Charles Stubbs at the Office of the Commissioners
of Patents, with their Petition, on the 5th May 1873.
We, JOHN STUBBS and WILLIAM STUBBS, of Wharton, in the County
of Chester, Salt Manufacturers, and CHARLES STUBBS, of Liverpool, in
the County of Lancaster, Engineer, do hereby declare the nature of
the said Invention for "IMPROVED APPARATUS FOR FILLING SACKS OR BAGS
WITH GROUND SALT, GRAIN, OR SIMILAR SUBSTANCES," to be as follows:-
The object of our Invention is to provide apparatus which shall
facilitate the operation of filling sacks or bags with ground salt, grain,

page_text: or similar substances, and at the same time cause the said substances to
be closely packed therein.
*The said apparatus is constructed as follows:-A bar carried in vertical
guides has its lower end forked and provided with a bow, around which
the open mouth of the sack to be filled is hooked. The forked bar is t
provided with a projecting piece, which being raised by a cam secured
on a revolving shaft gives to the said bar and suspended sack and
contents an upward movement; the weight of the bar, sack, and
contents causes them to fall a greater distance than they were raised,
return to their original position being secured by a spring or springs
secured to the bar and frame. The ground salt, grain, or other sub-
stance is fed to the sack by a hopper or shoot, and the up-and-down
motion of the sack causes such substance to be closely packed.

NOW KNOW YE, that we, the said John Stubbs, William Stubbs,

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 accompanying Sheet of illustrative Drawings, and to
the figures and letters marked thereon, that is to say :—
The object of our Invention is to provide apparatus which shall
facilitate the operation of filling sacks or bags with ground salt, grain,
or similar substances, and at the same time cause the said substances to
be closely packed therein.
The said apparatus is constructed as follows:-A bar carried in
vertical guides has its lower end forked and provided with a bow around
which the open mouth of the sack to be filled is hooked. The forked
bar is provided with a projecting piece, which being raised by a cam
secured on a revolving shaft gives to the said bar and suspended sack
and contents an upward movement; the weight of the bar, sack, and
contents causes them to fall a greater distance than they were raised,
return to their original position being secured by a spring or springs
secured to the bar and frame. The ground salt, grain, or other substance
is fed to the sack by a hopper or shoot and the up-and-down motions of
the sack causes such substances to be closely packed.
Two or more machines can be combined to work together.
