page_text: of the upper surface of the outer frame F 2. The bars when placed together as
in Fig. 5 in the drawings, form openings, one of which is shown, in section, on a
larger scale, in Fig. 6. The upper part of this opening is intended for the
reception of the lid of the tin, and is of the same shape as the said lid; and to
prevent the said lid from falling through the frame, a slight projection is provided
round the bottom edge of the upper part of the said opening. In the lower part
of the frame, a taper opening is provided, the upper part of which opening, is of
slightly smaller dimensions, than the opening in the upper portion of the frame,
which smaller opening forms the projection supporting the lids, as above mentioned.
To ensure the close fitting of the bars in the frame F, I provide firstly, that the
outer frame F 2 shall be longer from back to front, than is required to accom-
modate the necessary number of bars. Secondly I strengthen the bar nearest the
front of the outer frame F 2, by thickening it and thirdly, I provide two screws
working in the front portion of the frame F 2 (as shown in the drawing Fig. 5)
which when screwed up, exert pressure on the thickened front bar, and thus tighten
up the remaining bars. The taper openings, previously described, are so constructed,
that when the tin is forced upward through the said opening, pressure is exerted on
such parts of the tin, as may be out of truth with the lid, and the upper part of
the taper opening being of the same dimensions as the inside of the lid, a moderate
amount of pressure will force the tin through the taper opening, and thus into
the lid.
The mechanism here provided for the purpose of raising the moveable bottom D 1
of the tray D, consists of a platform J, to which are attached racks, two of which
are shown at H, H 1; these racks each being provided with a slide with angular
sides, working in a corresponding groove in one of the guide blocks I. or I 1. The
pinions L, L1 work mutually, but in opposite directions, and are fixed to the
shafts M, M 1, in such positions as to engage with the racks H, H 1, it being
necessary to have two pairs of pinions, and a corresponding number of racks.
The shafts M, M 1 work in bearings in each side of the framework of the machine,
and are further supported by the double bearings on the block K, which are for
the purpose of relieving the strain on the said shafts.
The fever G is attached to the end of the shaft M 1, in a convenient position for
working.
When the lever G is pulled over, the pinion L1 on the shaft M1 (to which
the said lever is attached) is caused to revolve, and engaging with the pinion L,
cause the pinion L to revolve also, but in an opposite direction. The teeth on
both pinions engaging with the teeth on the racks, give the said racks an upward
motion, thereby raising the platform J, to which the said racks are attached."
I do not limit myself to the particular method, or mechanism here described for
the purpose of raising the platform J, as it is obvious that various appliances might
be employed, which would accomplish the same object.
The method to be adopted in working the machine, is as follows:-
The frame F is removed and charged with the lids of the tins.
The tray D is also removed and charged with the tins to be filled.
The hopper A is filled with the substance required to be packed.
The tray E, with the slide C, is then withdrawn from the grooves E 3, E 3, and
placed in the grooves E1, E 1, thereby raising the tray E, close against the under
side of the slide B.
'
The slide B is then withdrawn, allowing the substance in the hopper A, to fall
into the tray E.
The slide B, is then replaced, thereby cutting or parting off, a certain quantity
of the substance to be packed, which quantity will be the same at each operation
of the machine, so long as the same substance is being manipulated. Any
desired quantity may thus be separated, thereby doing away with the necessity of
weighing.
The tray E, with the slide C, (the said tray being now filled with the substance
to be packed) is then restored to its original position; in the grooves E 3, E 3.

page_text: The frame F being charged with the lids of the tins, is replaced in its original
position immediately above the tray E.
The tray D, being charged with the tins to be filled, is then placed in its original
position, underneath the tray E.
The slide C is then withdrawn, allowing the substance already cut off in the
tray E, to fall into the tray D, part of the substance falling into the tins, and part
falling into the space between.
The lever G is then pulled over, causing the mechanism provided for the purpose,"
to raise the platform J.
The platform J continuing to rise, meets the moveable bottom D 1 of the tray D,
and the C having been already withdrawn, the said platform carries the said
moveable bottom, with the partly filled tins, up through the tray E (the fillets D4, D4,
passing up behind, and closing the apertures left by the withdrawal of the slide (),
and upward through the taper openings in the lower part of the frame F, into the
upper part of the said frame, where the lids of the tins have already been placed,
thus forcing the substance into the tin, and the tin into its lid.
The lever G is then put back to its former position, thereby lowering the plat-
form J, and with it the moveable bottom D 1, and the said moveable bottom continues
to descend until it meets with the fillets D2, D2, and is thus restored to its original
position in the tray D.
The tins do not descend with the moveable bottom D 1, but are held in the
openings of the frame F, partly by the projections provided for supporting the lids
(the tins fitting somewhat tightly into the said lids), and partly by reason of the .top
of the taper opening holding the sides of the tins."
The tray E with the frame F may then be withdrawn together, and the frame F
with the tins, lifted from the tray E.
The screws in the front part of the outer frame F 2, may then be unscrewed, thus
releasing the thickened front bar, when the bars may be drawn back, releasing a
row of tins each time a bar is shifted.
The slide C may then be replaced in the groove provided for it in the tray E,
and the tray E replaced in the groove E 1, E 1, ready for another operation.
The tray D now contains that portion of the substance which filled the spaces
between the tins, as previously mentioned, and which substance has fallen from
between the said tins when the moveable bottom D 1 was lowered into the tray D.
This can be removed in any convenient manner when the tray D is again withdrawn
for the purpose of charging with tins to be filled.
The frame F may now be again charged with the lids of the tins, and the whole
operation repeated, ad libitum.

The foregoing describes a convenient method of working the machine, but any
arrangement of the different portions of the operation, may be made according to
convenience.
It has been found in practice, that most substances of the nature of a powder,
can be packed in tins by this method, with sufficient exactitude to dispense with
the operation of weighing.
This invention is especially applicable to substances of an oily or clogging nature,
which substances would not readily pack into tins, by their own weight, but that
require to be, to some extent forced into the tins.
The working of the machine may be, considerably expedited, by having two.
attendants, one, I suggest, to fill the hopper, work the slides, and remove and
replace trays in the machine, as required, the other to charge the lid frames, and
tin tray, and remove the tins from the lid frame as required.
If the lid frame, and tin tray are duplicated still further time may be saved in
working the machine..

page_text: drawings form openings one of which is shown on a larger scale in Fig. 6. The
upper part of this opening is intended for the reception of the lid of the tin and is
of the same shape as the said lid, and to prevent the said lid from falling through.
the frame, a slight projection is formed around the bottom edge of the upper part
of the said opening. In the lower part of the frame a taper opening is provided;
the upper part of which opening is of slightly smaller dimensions than the opening
in the upper portion of the frame, and thereby forms the projection supporting the
lids of the tins as aforesaid. To ensure the close fitting of the bars, in the lid
frame. F, I provide-first-that the outer frame F 2 shall be longer from back to
front, than is required to accomodate the necessary number of bars. Second-I
strengthen the bar nearest the front of the outer frame F 2. by thickening it..
Third-I provide two screws E3 F3 which screws working through the front
portion of the outer frame F2 exert pressure on the thickened front bar, and thus
tighten up the remaining bars. The taper openings are so constructed as to exert
pressure on such parts of the tin as may be out of truth with the lid, and the upper
part of the taper opening being of the same dimensions as the inside of the lid, a
moderate amount of pressure will force the tin through the opening into the lid..
Brackets are provided at the back of the machine, supporting runners, the upper
set to carry the lid frame, and the lower set to carry the frame E. when they are
withdrawn from the machine.
The mechanism here provided for raising the moveable bottom of the tray D;.
consists of the attached racks H. H 1; these racks each being provided with a
slide at the back, which slide works in a corresponding groove in the guide block I.
The pinions L. LI work mutually but in opposite directions, and are fixed to the
shafts M. M 1, working in bearings in each side of the framework of the machine.
The lever G. is attached to the end of the shaft M 1 in a convenient position
for working.
t
When the lever G. is pulled over, the pinion L 1 on the shaft M 1 (to which the
said lever is attached) is caused to revolve, and engaging with the pinion L
causes the pinion L. to revolve also but in an opposite direction. The teeth of the
pinions engage with the teeth of the racks, giving the said racks an upward motion,
thereby raising the moveable bottom D 2 to which the racks are attached.
I do not limit myself to the particular method or mechanism here described>
for the purpose of raising the moveable bottom D2; as it is obvious that various
appliances might be employed which would effect the same object.
t
The method to be adopted in working the machine is as follows:-
The lid frame F is to be drawn out on to the bracket provided for its support,
and there charged with the lids of the tins.
The tray D is also withdrawn, together with the bedplate, which bedplate is
charged with the tins to be filled.
The hopper A is filled with the substance to be packed.
The frame E. with the slide C. is then withdrawn from the grooves E 3 E 3, and
placed in the grooves E 1 E 1, thereby raising the frame E close-up against the
under side of the slide B.

.
The slide B is then withdrawn, allowing the substance in the hopper A. to fall
into the frame E.
The slide B is then replaced, thereby cutting or parting off a certain quantity of
the substance to be packed, which quantity will be the same at each operation of
the machine, so long as the same substance is being manipulated.
The frame E. with the slide C. is then restored to its original position in the
grooves E 3 E 3..
The frame F being charged with the lids of the tins, is then run into the machine
from off the brackets supporting it.
The tray D being charged with the tins to be filled, is then replaced in its original
position underneath the frame E.
The slide C is then withdrawn, allowing the substance already cut off in the
frame E to fall between the partitions (previously described and. shown in Fig: 4)

page_text: into the tray D, and partly into the tins, and partly surrounding them in the said
tray. The lever G. is then pulled over, causing the mechanism provided for the
purpose to raise the moveable bottom D 2.
(*
The moveable bottom D 2. with the bedplate D 1 carrying the tins, now partly
filled, continues to rise, through the frame E, until the tins reach the taper openings
in the lower part of the frame F.; into the upper part of the said frame, where the
lids of the tins have already been placed, thus forcing the substance into the tins
and the tins into the lids.
The lever G. is then put back to its former position, thereby lowering the
moveable bottom D 2, and with it the bedplate D 1, down to their original positions
in the tray D.
:
The tins do not return with the bedplate D 1, but are held suspended in the
openings in the lid frame F, partly by the close fitting of the lids, and partly by
the pressure exerted on the sides of the tins, by the uppert part of the taper
openings.
The lid frame F with the frame E. are then withdrawn together, sliding on to
the runners on the brackets provided for them at the back of the machine.
The screws in the front part of the lid frame may then be unscrewed, thus
releasing the thickened front bar, when a slight shake given to the frame, will
release the tins, or the bars may be drawn back one by one, thus releasing a row
of tins each time. Any convenient receptacle may be used for the reception of the
tins as they fall from the lid frame.
་
The frame E may then be put back in the machine, and the slide C replaced in
the said frame. The tray D now contains some of the substance which will have
fallen from between the tins, when the moveable bottom and bedplate were lowered.
This may be removed as follows. The tray D with the bed plate D1 are free to
slide out over the moveable bottom D 2., so that when the tray D is drawn out of
the machine the bedplate comes with it carrying the surplus material, and
discharging it through the lower part of the bedplate, which is formed of inter-
secting bars, thus affording free passage for the material as aforesaid.
The frame F (which has not left the bracket) and the tray D may now be
charged again with lids & tins respectively, and the whole operation carried on
continuously.
To ensure the correct distribution of the substance in the frame E. partitions are
formed across the said tray in the positions shown in Fig. 4. This prevents the
material being disturbed by the withdrawal of the slide C. without interfering in
any way with the free passage of the tin upwards.
The foregoing describes a convenient method of working the machine, but any
arrangement of the different phases of the operation, may be made according to
circumstances.
It has been found in practise that most substances of a pulverulent nature,
can be packed in tins by this method, with sufficient accuracy to dispense with
weighing.
This invention is especially applicable to substances of an oily or clogging
nature, which substances would not readily pack into tins by their own weight, but
require to a great extent, to be forced into the tins.
Two attendants are necessary to work the machine, one to fill the hopper, and
tin tray and otherwise operate the machine, while the other fills and discharges the
lid frame.
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 machine for filling tins and putting lids on the same, in one operation,
First. The combination of bars forming the lid frame, with the device for
compressing the tin into the lid, and the means for adjusting the said bars.
Second. The combination of the frame E. with the slides B & C. and the

page_text: partitions in the frame E. whereby the tin is made to measure off the required
quantity of material to be packed.
Third. The combination of the clip plates, blocks and from of intersecting bars,
the whole forming the bedplate, for the purpose of getting rid of the surplus
3 material, which would otherwise prevent the action of the machine.
