PROVISIONAL SPECIFICATION.
A Novel or Improved Apparatus for Use in Charging and otherwise
Manipulating Sacks and the like Collapsible Receptacles.
I, EDWIN SHERWOOD, of the Kirkbridge Reaper Works, Bedale, in the
County of York, Farmer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to a contrivance or apparatus for holding up sacks and
the like collapsible receptacles to facilitate the operation of filling them and for
otherwise manipulating them when full in the manner hereafter described.
It has hitherto been the practice when filling sacks or the like collapsible
receptacles with grain, coals, or any other material for which sacks are used, for
one man to hold the sack up and keep its mouth open, whilst another man charges
the sack with its intended contents. The sack is then bodily removed as required
by muscular effort.
The object of this invention is to effect an improvement in this class of labour
in the direction of employing an apparatus or machine adapted to both hold the
sack up and keep its mouth open, and also to afford a means of leverage by which
the sack when fuil can be lifted and manipulated with facility, which apparatus is
simple in its construction and also por.able.
In its construction a centre or jack post is mounted on a stand so as to be capable

of carrying the lever and the weight of the sack when full.
short tube fits onto this jack post, so that its position is adjustable both vertically
and circumferentially. This fulcrum collar finds its seat on a similar collar or
tube which is secured to the jack post at any required position by a set screw.
The fulcrum collar thus supported is furnished with trunnions or pintles which
serve as the fulcrum of the lever which is bifurcated to embrace both sides of the
fulcrum collar. A square bar is transversely fitted into the arms of the bifurcated
end of the lever, and two arms or prongs are fitted onto this transverse bar so as
to be adjustable along its length, that is transversely to the movement, of the lever.
A clutching block is pivotally secured to each of these prongs and is furnished
with pegs or claws for gripping the jack. The several parts being arranged and
combined together in this manner, the sack is secured to the clutching blocks, the
position of the main lever having been previously adjusted by means of the set
screw collar. The clutch block prongs are set apart at the proper distance for
keeping the sack mouth open and the process of filling proceeds as though the
sack was held up and kept open by hand. When the sack is lifted by means of
the lever the clutch blocks retain the level position on their respective pivots and
furthermore inasmuch as the centre or jack post is round and preferably a tube
the main lever can swing round it on the fulcrum collar through the entire circle.
Thus the apparatus as constructed according to my invention affords the means
of holding up the sack mouth open for the operation of filling and also provides
facilities for readily lifting the sack when full and swinging it round to some other
position and level to facilitate its removal in the usual way.

Manipulating Sacks and the like Collapsible Receptacles.
I, EDWIN SHERWOOD, of the Kirkbridge Reaper Works, Bedale, in the
County of York, Farmer, 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 relates to a contrivance or apparatus for holding up sacks and
the like collapsible receptacles to facilitate the operation of filling them and for
otherwise manipulating them when full in the manner hereinafter described.
It has hitherto been the practice when filling sacks or the like collapsible
receptacles with grain, coals, or any other material for which sacks are used, for
one man to hold the sack up and keep its mouth open, whilst another man charges
the sack with its intended contents. The sack is then bodily removed as required
by muscular effort.
The object of this invention is to effect an improvement in this class of labour
in the direction of employing an apparatus or machine adapted to both hold the
sack up and keep its mouth open, and also. to afford a means of leverage by which
the sack when full can be lifted and manipulated with facility, which apparatus is
simple in its construction and also portable.
And in order that my invention may be fully understood and readily carried
into effect, I will now proceed to describe the same with reference to the
accompanying drawing, in which Fig. 1 is a side elevation (partly in section, and
sbowing an empty sack held up to be filled) and Fig. 2 a corresponding plan of a
machine or contrivance constructed according to my invention.
A centre or jack post a is mounted on a stand b so as to be capable of carrying
the lever cand the weight of the sack when full. A fulcrum collar or short tube d
fits onto this jack post so that its position is adjustable both vertically and circum-
ferentially. This fulcrum collar & finds its seat on a similar collar or tube e which
is secured to the jack post at any required position by a set screw el. The fulcrum
collar thus supported is furnished with trunnions or pintles d' which serve as the
fulcrum of the lever.c which is bifurcated to embrace both sides of the fulcrum
collar. A square bar f is transversely fitted into the arms of the bifurcated end
of the lever, and two arms or prongs 9 are fitted into this transome bar so as to be
adjustable along its length, that is transversely to the movement of the lever c.
A clutching block is pivotally secured to each of these prongs and is furnished
with pegs or claws A' for gripping the sack. The several parts being arranged
and combined together in this manner the sack is secured to the clutching
blocks h, the position of the main lever c having been previously adjusted by
means of the set screw collar e. The clutch block prongs g.are set apart at the
proper distance for keeping the sack mouth open and the process of filling
proceeds as though the sack was held up and kept open by hand.
When the sack
is lifted by means of the lever c the clutch blocks retain the level position on
their respective pivots and furthermore inasmuch as the centre or jack post a is
round and preferably a tube the main lever c can swing round it on the fulcrum
collard through the entire circle.
Thus the apparatus as constructed according to my invention affords the means
of holding up the sack mouth open for the operation of filling and also provides
facilities for readily lifting the sack when full and swinging it round to some other
position and level to facilitate its removal in the usual way.

page_text: 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 :-
In a sack holder, the arrangement and combination of parts by which the sack
is held up with its mouth open and by which the sack when full can be lifted and
manipulated with facility, substantially as and for the purpose as hereinbefore
described with reference to the accompanying drawing.
