Office of the Commissioners of Patents on the 1st May 1878.
WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London. AN IMPROVED APPARATUS OR MACHINE FOR
FACILITATING THE FILLING OR CHARGING OF SACKS OR BAGS AND FOR SIMILAR
PURPOSES." [A communication from abroad by Emile Cartier, of Paris, France.]
This Invention relates chiefly to an improved apparatus or machine designed to
facilitate the filling or charging of sacks or bags, the said apparatus comprising
devices whereby the sack or bag is held open, and suspended in a vertical position
to receive the materials to be placed therein. Also devices whereby it may be
instantaneously detached from the apparatus at the desired moment, all being.
arranged so that one man may perform all the operations necessary for filling the
sack or bag with the materials which it is to contain.
The said improved apparatus comprises a hopper, the opening of which is
arranged in a vertical position, so as to facilitate the operation of filling with a
shovel.
In constructing an apparatus according to this Invention I provide a frame, at
the upper part of which is placed the said hopper, having a mouth bent round,
which brings into a vertical position the opening of the said hopper, below which
the sack or bag is suspended by means of a collar.

page_text: I provide a disengaging device, by means of which the edge of the sack may be
instantaneously released from the position in which it is held between the collar
and metal tappets provided to hold it during the operation of filling.
I prefer to construct the said apparatus entirely of metal, excepting the hopper,
which may be of wood or metal.
I construct the said frame in the form of a stand with three legs, made of angle
iron. Two of the said legs are united at their upper end by a cross piece, and are
secured by means of nuts, the proper relative position of these two legs being
maintained by two stay pieces, which are each rivetted or bolted at one end to the
said cross piece, and at the other end to the two legs.
The third leg, herein-after called the movable leg, is attached at its upper end by
a jointed connection to the centre of the said cross piece, and may be kept in any
desired position by means of a hook, chain, or other suitable means.
To the upper part of the two first-named legs, which are herein-after called the
fixed legs, is attached by means of nuts a cylindrical rod parallel to the said cross
piece, which rod serves as a point of attachment and as a hinge or joint for the
aforesaid hopper and a collar. Below the said cross piece there is another rod
secured by a nut to the two fixed legs, the said rod being provided with two pro-
jecting pieces, which are designed to grasp in two places the edge of the sack placed
upon the collar. This rod turns freely upon itself, and is secured by means of a
socket or sleeve, which is fixed at one of its ends, and which has at its periphery a
tooth, which enters a cavity of the same dimensions provided in a socket, which
has a handle, and is capable of turning freely on a cylindrical extension of the
cross piece, on which it is held by means of a nut.
The devices herein described for fixing the projecting pieces in the position in
which they grasp the edge of the sack may be replaced by any other equivalent
devices which will allow of an instantaneous change of position, so as to release
the sack at the moment desired.
The hopper, which may be of wood or metal, is jointed by means of suitable
pieces to the aforesaid upper horizontal rod in such a manner as to be capable of
turning back when it is desired to detach the sack from the apparatus.
When the hopper is constructed of wood I provide upon it a piece of metal at
the part where, in turning back, it would come against the movable leg, so that the
hopper may not be damaged by reason of the shock or blow at that part.
The said hopper is provided on its jointed face or side with an opening, which
comes just above the aforesaid collar, supporting the sack, and the hopper is at that
point provided with a kind of mouth-piece formed by its faces, the outer opening
of the hopper being in a vertical plane, thus permitting the rapid filling of the sack
by means of a shovel.
The aforesaid collar is terminated by two joints, which are traversed by the said
upper rod, and near these joints a part is bent back, so as to form two pieces,
which come against the said projections designed to gripe and hold upon the mouth
of the sack at that side.
In order to suspend the sack it is passed inside the said collar, its edges being
folded over the latter, and a portion of the part folded between the said pieces of 4
the collar and the projections on the lower rod is grasped by each hand of the
attendant; then a length of the folded sack is completely doubled over the first
part of the collar.
When the sack has been filled the said handle is operated, the
projections on the lower rod immediately descend slightly, and the sack, which
they hold suspended, falls off. In order to place another sack in position the 5
hopper is lowered, and the edge of the sack is griped, projections on the lower rod
being raised by means of the handle.
I wish it to be understood that I may vary to some extent the forms and
dimensions of the various parts and the material of which they are constructed, and
that I may also apply my herein-described vertical-mouthed hopper to other 5
apparatus, in which the filling is operated by means of a shovel.

page_text: A hopper constructed according to my said Invention is specially suitable for the
filling of materials into mills and pounding or crushing apparatus, and may be
used for manure, ores, and any other matters.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said William Robert Lake in the Great Seal Patent Office on the 1st
November 1878.
WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London. "AN IMPROVED APPARATUS OR MACHINE FOR
FACILITATING THE FILLING OR CHARGING OF SACKS OR BAGS AND FOR SIMILAR
PURPOSES." A communication from abroad by Emile Cartier, of Paris, France.
This Invention relates to an improved apparatus or machine chiefly designed to
facilitate the filling or charging of sacks or bags.
The said apparatus comprises devices, whereby a sack or bag is held open, and
suspended in a vertical position to receive the materials to be placed therein, and
whereby it may be instantaneously detached from the said apparatus at the desired
moment, and which are arranged so that one man may perform all the operations
necessary for filling the sack or bag.
The said improved apparatus also comprises a hopper, the opening of which is
arranged in a vertical position to facilitate the operation of filling the sack with a
shovel.
In constructing an apparatus according to this Invention I provide a frame, at
the upper part of which is placed the said hopper, having a mouth-piece so formed
as to bring into a vertical position the opening of the said hopper, and below the
latter the sack or bag is suspended by means of a collar.
I provide a disengaging device, by means of which the edge of the sack may be
instantaneously released from between the collar and metal tappets provided to
hold it during the operation of filling.
In the accompanying Drawing I have shewn an example of my improved
apparatus.
Figure 1 is a front elevation of the said apparatus; Figure 2 is a vertical trans-
verse section thereof; Figure 3 is a side elevation of part of the same.
Figure 4 is a plan or top view of the said apparatus with the upper part
removed.
I prefer to construct the said apparatus entirely of metal, excepting the hopper,
which may be of wood or metal.
I construct the said frame in the form of a stand with three legs, made of angle
iron. The two legs A are united at their upper end by a cross piece B, and are
secured by means of nuts, the proper relative position of these two legs being.
maintained by two stay pieces C, which are rivetted or bolted at one end to the
said cross piece, and at the other end to the two legs A.

page_text: The third leg D is jointed at its upper end to the centre of the said cross piece B,
and may be kept in any desired position by means of a hook, chain, or by other
suitable means.
To the upper part of the two first-named legs A is attached by screw nuts a
cylindrical rod E parallel to the said cross piece, which rod serves as a point of
attachment, and as a linge or joint for the aforesaid hopper F and for the collar G,
which supports the sacks to be filled. Below the said cross piece there is a rod H
secured by a nut to the two legs A, the said rod being provided with two pro-
jecting pieces or arms I, which are designed to grasp in two places the edge of the
sack placed upon the collar G. This rod is free to turn freely on its axis, and is
secured by means of a socket or sleeve J, which is fixed at one of its ends, and
which has at its periphery a tooth, which enters a cavity provided in a socket K,
which has a handle I, and is capable of turning freely on a cylindrical extension of
the cross piece B, whereon it is held by means of a nut.
It will be obvious that the devices above described for fixing the projecting
pieces I in the position in which they grasp the edge of the sack may be modified
or replaced by others, which will allow of an instantaneous change of position to
release the sack at the moment desired.
The bopper F, which may be of wood or metal, is jointed by means of suitable
pieces M to the aforesaid upper horizontal rod E in such a manner as to be capable
of turning down into the position indicated by dotted lines in the Drawing, when
it is desired to detach the sack from the apparatus.
When the hopper is constructed of wood, I provide upon it a piece N of metal
at the part where, in turning back, it would come in contact with the leg D, so
that the said hopper may not be injured by a shock or blow at that part.
The lower part of this hopper has in its jointed face or side an opening O, which,
when the hopper is in the position shown in full lines, is just above the aforesaid
collar G, supporting the sack P, and the upper part or mouth-piece Q of the hopper
is so arranged that its opening or mouth occupies a vertical plane, and thereby
permits the rapid filling of the sack by means of a shovel.
The metal collar or suspender G is terminated by two joints R, which are
traversed by the said upper rod E, and near these joints a part is so bent back as
to form two claws or pieces, which meet the said projections I, designed to gripe
and hold open the mouth of the sack at that side.
To suspend a sack, the same is passed inside the said collar P, its edges being
folded over the latter, and a portion of the part folded between the said claws and
the projection I is grasped by each hand of the attendant; then about two fingers'
length of the folded sack is completely doubled over the back part of the said
collar. When the sack has been filled the handle L is operated, the projections I
immediately descend slightly, and the sack suspended thereby falls off. To place
another sack in position for filling the hopper is lowered, and the edge of the sack
is griped by raising the projections I by means of the handle.
Having thus fully described the said Invention as communicated to me by my
foreign correspondent, and the manner of performing the same, I wish it understood
that I may vary to some extent the forms and dimensions of the various parts, and
the material of which they are constructed, and that I may also apply the herein-
described vertical-mouthed hopper to other apparatus, in which the filling of the
sacks or bags is effected by means of a shovel; and that a hopper constructed
according to the said Invention is specially suitable for mills, pounding or crushing
apparatus, and for loading manure, ores, and other materials, and I claim, the
improved apparatus above described and shewn in the accompanying Drawing, and
which is characterized essentially by the following features, namely:
First. The device or mechanism for effecting the instantaneous release of the sack
from-its points of attachment at the moment when the same is to be displaced, as
above set forth.
Second. The means for attaching and suspending the sack, whereby the same

page_text: may be kept suspended and open during the operation of filling the same, as above
set forth.
Third. The hopper with a vertical opening, and so arranged at the upper part of
the said apparatus as to permit the rapid filling of the sack by the aid of a shovel,
as above set forth.
In witness whereof, I, the said William Robert Lake, have hereunto set my
hand and seal, this Thirty-first day of October, in the year of our Lord
One thousand eight hundred and seventy-eight.
