IMPROVEMENTS IN THE METHOD OF AND APPARATUS FOR CLEANING, MILLERS, CORN FACTORS, AND OTHERS SACKS
Year: 1885

page_text: I'TOM CLUDERAY, of Airedale Villas, 82, Bradford and Otley Road, Shipley, in
the County of York, Corn Factor, do hereby declare the nature of my invention
for "IMPROVEMENTS IN THE METHOD OF AND APPARATUS FOR CLEANING, MILLERS,
CORN FACTORS, AND OTHERS SACKS," and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
The object of this invention is to clean Millers and Corn Factors Sacks, by means
of machinery whereby they can be cleaned more efficaciously and in less time than
hitherto.
I accomplish my object in the following manner.
I construct twin casings of the desired length having circular sides, uniting in a
hopper placed on the top in the middle of both the casings and of the length
thereof. In the centre of the casing I mount two horizontal square shafts in
suitable journals, and upon each square shaft I attach revolving brushes in the
manner hereinafter described, and to which motion is imparted in the direction
that both brushes revolve inwards by means of a driving pulley upon one shaft
and spur gearing connecting the two shafts, the gearing being enclosed in casings
for protection.
To two sides of the square shafts I secure two strips of sheet iron projecting
outwards in opposite directions of the same length as the wood work of the brushes
which is secured by bolts, and by the slots in such sheet iron, I am enabled to
regulate the wear and tear of the brushes, and maintain them at such a distance
apart that the brushes on one shaft project within the circumference described by
the brushes on the other shaft; the brushes on one shaft being vertical and those
of the other horizontal and secured relatively in this position by the spur gearing.
When it is desired to clean the sacks the machine is set to work, and the sack,
after being turned inside out, is taken in hand at the two corners of one end and
lowered through the hopper, when the revolving brushes thoroughly clean the sack
by their inward rotary motion; the sack is then held by the other two corners and
again subjected to the action of the brushes. .
In order to prevent the sacks being drawn in by the brushes; I secure to suitable
castings at the bottom, at required distances, and in sufficient number, iron or
steel guards curved in the opposite direction to the rotation of the brushes.

page_text: The dust and dirt from the dirty sacks is driven out at the bottom by means of
the centrifugal motion of the brushes, and can be driven by such means to any
convenient position and disposed of.
The accompanying drawings Figs. 1. 2 and 3 shew more clearly my invention
and in what manner the same may be carried out.
Fig. 1 represents an end elevation and part section through one of the casings.
H, is the hopper through which the sacks are introduced between the revolving
brushes B, B, attached to shafts S, S, through the medium of the strips of sheet
iron I, I, secured to shaft by rivets at R, and having slots K, K, for regulating the
wear and tear of the brushes B, B, enclosed.by. the casings C, C.
P, P, are the journals carrying the shafts at each end of the casings, and G G are
the guards bent inwards, secured to the castings A, A; at the bottom, O is the
opening for the dirt to make its exit from the machine; D, is the driving pulley,
and W, W, are the spur gearing encased in N, N, for ensuring the proper motion
inwards and relative position of the brushes.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is
The cleaning of sacks substantially in the manner herein described and set forth.
