PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Packing Powdered or Granulated
Substances.
I, ROBERT HOLMES of 8, Queen Street, Keighley in the County of York,
Grocer and Baking Powder Manufacturer, do hereby declare the nature of this
invention to be as follows, that is to say :-
It relates to improvements in apparatus for packing or forming packets of given
quantities of granulated or powdered substances and consists of an arrangement
and construction of mechanism by the employment of which the process of said
packing or forming into packets is greatly facilitated.
Respecting the means or mechanism for measuring given quantities from the
bulk of any granulated or powdered substance, I make use of a trough or box,
which I mount upon wheels or runners that operate upon suitably formed frame-
work, so that said box or trough may be moved by the operator from one side to
the other of the said framework.
The said box or trough is for the reception of the granulated or powdered
substance that has to be packed, and in order to facilitate the package of said
substance said box or trough is made to taper towards its bottom part to guide
same so that, when permitted, it may fall and pass through a series of hoppers
leading from the bottom of said trough into a cavity or receptacle for measuring it.
The receptacle for measuring the given quantity consists of a rectangular frame
which is divided by a series of partitions to form spaces for holding the desired
quantity of powdered substance to be packed, the number of said series of spaces
corresponding with the number of hoppers in the trough above them, and said
partitions are sufficiently broad to cause the measuring spaces to be a distance apart
equal to or slightly greater than is their measurement taken in the direction length-
wise of the rectangular frame.
Another series of shoots or hoppers are arranged beneath this rectangular frame
and correspond in number with the measuring spaces within it as also with the
hoppers in the trough above, and these lower hoppers or shoots are further arranged
so as not to be in line with or in the same vertical planes as are the upper series
of hoppers but each lower hopper is located opposite one or another of the spaces
that intervenes between said upper series of hoppers, by which means when the
rectangular frame, which is arranged to be operated by the operative by suitable
handle and other lever mechanism, is moved so that its measuring spaces are
opposite the upper, hoppers, the substance to be packed or measured descends
into and fills them, and on moving the rectangular frame in the opposite direction
so that its 'measuring spaces may be brought over the lower hoppers, the substance
in the trough 'above is cut off and only such quantities of it as are. held in the
measuring spaces of the rectangular frame, are permitted or brought into position
for passing through the hoppers beneath.
Under certain conditions and in order to be enabled to allow less space between
each of the hoppers so that the operative may more readily attend to a large
number of them, I employ an additional cutting off plate between the rectangular
frame and the upper series of hoppers. This cutting off plate being placed
in this position enables me to have the upper hoppers placed with their longest
length at right angles to the longest way of the hoppers beneath so that the
whole series occupies less space lengthwise the machine than they otherwise
would. Handle or other lever mechanism is employed for operating this cutting
off plate as may be desired, but by same resting upon, so as to be in frictional
contact with the rectangular frame beneath its return movement to open the

page_text: passage between said frame and the upper series of hoppers on the moving of
said frame into this position is performed without the aid of said handle or lever
mechanism.
On each side of the framework supporting the trough or box above described,
is mounted holding mechanism for the receipt of the paper or other wrappings
that have to be filled with the substance from the said trough.
This holding mechanism in case metal coverings, cans or cartridge cases are
the wrappings to be filled, consists of partitioned framework into each cavity of
which one or other of these wrappings is to be placed so that on the 'substance
in the trough having descended into the measuring spaces of the rectangular
frame, by said trough being brought with its series of lower hoppers immediately
over the series of wrappings, on the withdrawal of the rectangular frame said
measured quantities of substances are deposited into the wrappings beneath,
leaving the trough and its contents together with its measuring and guiding parts
at liberty to be moved by the operative to the other side of the frame to treat in
like manner other wrappings in the framework on that side, thus one operative
may be stationed on one side while another is on the other side of the same
machine.
When paper covers are the wrappers that are to be filled, I form these covers
by baving a rectangular trough-like article, open at each end, over which I place
each sheet of paper that is to form the wrapper, singly, and upon this sheet. of
paper bring a block that fills said trough and presses the paper into it, so that
its two sides are brought, at one operation, at right angles to each other, the other
foldings of the paper over the block being completed in the well known manuer.
The series of receptacles in the machine that are to receive these paper wrappers
are formed by three of the walls of each receptacle being formed on one frame while
the remaining wall is formed on another frame to which the former is hinged and
otherwise attached in such a manner as to be readily moved by the operative.
When the paper wrappers are formed they are placed in their respective
receptacles on the one frame which is then moved to bring them into an upright.
position and hold them ready for the substance to be deposited therein, on which,
a rail carrying a series of rammers and mounted in suitable guide slots of the
framework, is brought into use for compressing the substance within said wrappers,
its return movement being effected by retracting springs.
To fold the upward extending end of the paper wrappers I mount two series of
lever arms on a hinged plate, this plate being so hinged that it may be raised into
position whenever desired, and its lever arms are so formed that by a handle and
suitable connecting rods, they may be caused to fold the two sides of each of the
wrappers simultaneously, the other sides being folded by an additional folding
piece having thin plates that may be withdrawn when any part of the wrapper is
olded over them without in the least disturbing the parts thus folded.

Improvements in Apparatus for Packing Powdered or Granulated
Substances.

I
I, ROBERT HOLMES of Number 8 Queen Street Keighley in the County of York,
Grocer and Baking Powder Manufacturer, 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, that is to say :-
It relates to improvements in apparatus for packing or forming packets of
given quantities of granulated or powdered substances, and consists of an arrangé-

page_text: ment and construction of mechanism by the employment of which the process of
said packing or forming into packets is greatly facilitated.
In the accompanying sheets of drawings:-
Figs., 1 and 2 are front and end elevations respectively of my improved
mechanism.
Figs. 3 and 4 are sectional front elevations of a portion of and mechanism
illustrating the respective and relative positions of certain of the parts as herein-
after explained.
Fig. 5 is sectional end elevation of the parts shown by Fig. 3.
Figs. 6, 7 and 8 are drawings in perspective of parts hereinafter described.
Respecting the means or mechanism for measuring given quantities from the
bulk of any granulated or powdered substance, I make use of a trough or box 2,
which I mount upon wheels or runners 3, that travel upon suitably formed frame-
work 4. so that said box or trough 2 may be moved by the operator from one side a
to the other side b of said framework 4.
The said box or trough 2 is for the reception of the granulated or powdered
substance that has to be packed, and in order to facilitate the package of said
substance said box or trough 2 is made by the wedge shaped spacing pieces cas
well as by its own outer walls, to taper towards its bottom part to guide said,
substance so that, when permitted, it may fall and pass through a series of hoppers 5
leading from the bottom of said trough 2 into cavities or receptacles 6 for
measuring it.
The series of receptacles 6 are formed in a rectangular frame extending from
one side of the machine to the other, and their sizes or dimensions regulate or
measure the substance in desired quantities. The receptacles 6 correspond in
number to that of the hoppers 5 and the partitions 7 between these receptacles 6
are sufficiently broad to cause the measuring spaces or receptacles 6 to be a
distance apart equal to or slightly greater than is their measurement taken in the
direction lengthwise of the rectangular frame.
Another series of shoots or hoppers 8 are arranged beneath this rectangular
frame and said shoots 8 correspond in number with the receptacles 6 as also with
the hoppers 5, and these lower hoppers or shoots 8 are further arranged so as not
to be in line with or in the same vertical planes as are the series of hoppers 5 but
each lower hopper 8 is located opposite one or another of the spaces that.
intervenes between said upper series of hoppers 5, by which means when the
rectangular frame (which is arranged to be operated by the operative by the
handle 9 lever mechanism 10 and 11) has moved so that its measuring spaces 6
are opposite the hoppers 5 as shewn by Fig. 4 the substance to be packed or
measured descends into or fills said receptacles 6, and on moving the rectangular
frame in the opposite direction so that its receptacles 6 are brought over the
lower hoppers 8 as shown by Fig. 3, the substance in the trough 2 is cut off and
only such quantities of it as are held in the spaces 6 are permitted or brought into
position for passing through the hoppers 8.
Under certain conditions, as when the substance is dry and finely powdered, and
in order to be enabled to allow less lateral space between each of the hoppers 5
and 8 so that the operative may more readily attend to a large number of them,
I employ an additional cutting off plate 12 between the rectangular frame or the
receptacles 6 and the hoppers 5. This plate 12 being placed in this position enables
me to have hoppers placed with their longer lengths at right angles to the
longest length of the hoppers 8 so that the whole series occupy less space length-
wise the machine than they could otherwise be arranged to do.
The handle 13 or other lever mechanism may be arranged to operate the plate 12
as is desired for cutting off the substance in the hoppers 5 from that in the
receptacles 6, however the return movement of this plate 12 for opening the
passage as will be understood is effected with that of the rectangular frame
carrying the said receptacles 6, by reason of said plate resting upon and being in
frictional contact with said rectangular frame.

page_text: On each side a and b of the framework 4, are mounted holding mechanisms 14
(shown in broken lines Fig. 2) for the receipt of the paper or other wrappings
that have to be filled with the substance from the trough 2.
This holding mechanism 14 in case metal coverings, cans or cartridge cases are
the wrappings to be filled, consists of simple partitioned framework into each
cavity of which one or other of these wrappings is to be placed, so that on the
substance in the trough 2 having descended into the receptacles 6, by said trough 2
being brought by being moved on the framework 4, with its series of lower
hoppers 8 immediately over the series of wrappings, on the withdrawal of the
rectangular frame by the handle 9 said measured quantities of substance in the
receptacles 6 are deposited into the wrappings beneath, leaving the trough 2 and
its contents together with its measuring and guiding parts at liberty to be moved
by the operator to the other side of the framework 4 to treat in like manner other
wrappings in the holders 14 on that side, thus one operative may be stationed on
one side while another is on the other side of the sanie machine.
When paper covers are the wrappers that are to be filled, I form these covers
by having a rectangular trough-like article 15 (see Figs. 6 and 7) open at each
end over which article 15 I place each sheet of paper that is to form the wrapper,
singly, and upon this sheet of paper I bring a block 16 (see Fig. 8) that fills said
trough 15 and presses the paper into it so that its two sides are brought, at one
operation, at right angles to the part beneath the block, the other foldings of the
papers over the block 16 are then completed or executed in the well known manner,
firmness of the whole wrapper when thus folded being secured by the part 15"
hinged to the part 15 being brought forcibly over the same while the block 16
remains within.
The series of holders in the machine when arranged for receiving these paper
wrappers are formed by three of the walls d, e and f(see Fig. 9) of each receptacle
being formed on one frame 17 while the remaining wall is formed by another
frame 18 to which the frame 17 is hinged (as at g) while its upper edge may be
laid hold of by the catch 19 or otherwise be thereto attached in such a manner as
to be readily removed or detached by the operative.
When the paper wrappers F are formed as hereinbefore described they are
placed in their respective receptacles or troughs def on the frame 17 while in
its horizontal position, this frame is then moved on its hinges g to bring the
wrappers into an upright position and hold them ready for the substance to be
deposited therein, on which, a rail 20 carrying a series of rammers 21 and mounted
in suitable guide slots 22 of the framework 23, is brought by the hand wheel 24
pinions 25 and 26 and racks 27 and 28, into use, for compressing the substance
within its said wrappers, the return movement of said rail 20 and its rammers 21
being assisted or effected by retracting springs 29 and 30.
To fold the upward extending end of the paper wrappers I hinge the rail 31 to
the frame 18 and on this rail 31 are formed, projecting pieces 32 that are brought,
on the trough 2 being moved clear of the part 14, and the rail 31 being raised on
its hinges, so that they press one side of each of said wrappers into position
while the other foldings are readily executed by the operative.
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. Mechanism for packing given quantities of powdered or granulated substances
substantially as herein specified.
2. In mechanism for packing powdered or granulated substances the employ-
ment of a moveable trough or receptacle for said substances arranged so as to
deliver same on either side or both sides of the machine substantially as specified.
3. A rectangular frame having a series of receptacles for measuring given
quantities of substance, arranged to be moved upon a trough carrying said
substance, means for operating said rectangular frame, and said trough having

page_text: upper and lower hoppers arranged as described all in combination substantially as
specified.
4. The trough 2 having hoppers 5, and 8 the rectangular frame having
receptacles 6, and the cut-off plate 12 in combination substantially as set forth.
5. In a machine for packing powdered or granulated substances, the employ-
ment of the hinged device for holding the wrappers substantially as herein set
forth and described.
6. Means for folding sheets of paper in order to form same into wrappers
substantially as herein described and as illustrated by Figs. 6 and 7.
