WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London. "IMPROVEMENTS IN APPARATUS OR MACHINERY
FOR PUTTING UP OR MAKING PACKETS OF SEIDLITZ OR OTHER POWDERS." A coni-
munication from abroad by Charles Russell Doane, of Brooklyn, New York, United
States of America, Doctor of Medicine.
The object of this Invention is to provide apparatus or mechanism for putting
up seidlitz or other powders in paper, and this object is accomplished by the
employment and combination of the devices herein set forth.
The said apparatus has a basc or bed plate which has an opening near each of its
sides, and supports at each side two upright plates arranged inside and outside of
the said openings. It also supports a tall upright rear piece which has at its top
a platform for supporting two receptacles, whence the powders pass down into
funnels on the upper end of tubes that are supported by long rigid bracket arms
attached to said rear piece. These tubes are provided with sleeve pinions attached
to them by a pawl and ratchet that gear with and receive motion from a spur
wheel on a vertical shaft journalled in the said bed plate and platform. The said
tubes have teeth formed upon them, which engage with and turn pinions on small
shafts. These small shafts are journalled in the said bracket arms, and one of
them is arranged in front and one behind each of said tubes; each front shaft is
provided with two rollers, and each corresponding rear shaft is provided with a
Davies 11

page_text: similar roller. The lower roller carrying ends of said shafts are pressed toward said
tubes by springs attached to the said inner upright plates. Two rigid cylindrical
casings surround the lower part of each tube with space between them and the
tube; the front and rear of each casing are open to allow rollers to be pressed
against the tube. The vertical shaft is provided near its lower end with a large
crown wheel or bevel wheel that meshes with and alternately receives motion from
and communicates motion to pinions that are carried by short crank shafts
journalled in the pairs of upright plates at the opposite sides of the apparatus.
Each of these pinions has attached to it a spur pinion, which communicates motion
to another pinion on a similarly journalled shaft, and also through a small pinion
to a larger cog wheel loose on another shaft. The crank shafts carry rubber covered
rollers. A loose wheel is provided with a spring catch which is adapted to engage
with a pin on a cog wheel turning with the cog wheel shaft, and this engagement
is effected whenever a pin on the said shaft is struck by an arm on the upright
main shaft, thereby communicating motion to another gear wheel turning with and
fastened to suitable shaft. These shafts carry cain-shaped jaws, which are faced
with india-rubber; one jaw is provided with a transverse metal ridge or blade, and
the other jaw with a box or trough adapted to receive the same.
One shaft carries a snail cam that operates on a pin on another shaft, which
carries a bent folding bar and a coiled spring that tends to force said folding bar
downward toward the roller.
Each powder receptacle is perforated at the bottom, and a cut-off disc provided
with registering perforations is turned just above the bottom by a shaft. Shafts
below the said receptacle arc provided with discs, having studs adapted to be
engaged by a spring catch on a bifurcated arm turning with a sleeve on one of the
said shafts. These bifurcated arms are turned alternately by the operation of arms
on the aforesaid vertical shaft. Each of the said disc shafts carries a stirrer for
the powder in the said receptacle; one of said stirrers consists of a pair of curved
arms of uneven length, and the other consists of a post carrying a number of radial
rods, which operate the blades or vanes of a rotating fan journalled to the inside
of its said receptacle. On the inside of each receptacle, above the opening in the
plate which forms its bottom, is a block; on the under side of this block is a flat
spring, which forces the powder out of the apertures in the cut-off disc as they
successively pass underneath said block; on the opposite side of the said receptacle
is a similar block furnished on its under side with a flat spring, and having through
it a screw, by screwing down which a spring is forced downward into the regis-
tering apertures in the said disc.
A collar turning with the said vertical shaft is provided with horns which operato
upon the tails or rear points of pivoted diverging jarring arms to withdraw their
outer ends or hammers from the powder conducting tubes; the said hammers are
actuated by suitable springs. The said jarring arms serve to loosen any powder
which may adhere to the inside of the tubes, and thus prevent the choking of the
said tubes. A crank shaft is arranged in a convenient part of said apparatus, and
provided with a belt wheel to which power may be applied. When this wheel is
turned a half revolution one crank draws upon the belt sufficiently to cause a half
revolution of the main shaft, and when a further half revolution of the said wheel
takes place the other crank performs a similar office for a wheel and shaft on the
other side of the machine. The revolution of the said belt wheel thus produces the
necessary motion to work the machine by foot or other power as the cranks do by
hand; the machine may also be operated by a lever on the main shaft.
The aforesaid receptacles may be provided with devices for regulating the supply
of powder, and packing it as it descends through the cut-off.

WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London. “IMPROVEMENTS IN APPARATUS OR MACHINERY
FOR PUTTING UP OR MAKING PACKETS OF SEIDLITZ OR OTHER POWDERS." A com-
munication from abroad by Charles Russell Doane, of Brooklyn, New York, United
States of America, Doctor of Medicine.
The object of this Invention is to provide apparatus or machinery for putting
up seidlitz or other powders in paper, and the said Invention comprises the con-
struction, arrangements and combination of the devices, as herein-after set forth.
The said Invention is illustrated in the accompanying Drawing, in which,-
Figure 1 is a sido elevation of my improved machine; Figure 2 is a front
elevation thereof; Figure 3 is a central vertical section of the same:
Figure 4 is a central sectional view of the receptacles, herein-after described, and
Figure 5 is a plan thereof; Figures 6, 7, and 8 shew details of the same.
Figure 9 is a horizontal sectional view, and Figures 10 and 11 shew details.
Figure 12 is a front view, herein-after described, and Figure 13 is a transverse
section on the line x, x, of Figure 12 detached.
A represents the base or bed plate of the machine, which has an aperture a¹ near
each side, and also supports at each side two upright plates A¹ and A³ arranged on
the inner and outer sides of said openings. The base or bed plate A has an upright
standard B, which has at its top a platform C for supporting two receptacles D, in
which the powders are placed to be measured and fed to the machine below by the
feeding mechanism herein-after described.
The platform C forms the bottom for the two cylindrical receptacles or hoppers D,
and in the said bottom is a feed opening d for each hopper. Within each hopper D
is a circular rotating disc D', provided with a series of delivery or measuring per-
forations d', arranged in a circle concentric with the hopper and at equal distances
apart. This disc has a stem or shaft De passing downward through the platform C,
and provided below the same with a disc D³ secured to it. This disc is provided
with a series of studs & arranged in a circle at equal distances apart, as shown in
Figure 8, and which projects from the lower side, and are operated upon one by
one by a spring catch attached to a bifurcated arm D', placed loosely on the
shaft D. The two arms D*, D, are operated alternately by means of arms H*, H*,
secured upon the vertical operating shaft H, and provided with studs at their
outer ends. The shaft H is placed in suitable bearings in the base A and plat-
form C, and is operated to rotate first in one direction and then in the other.
When the shaft H is turned in one direction one of its arms H+ will operate the
bifurcated arm D' on that side and turn the feeding disc D', so that the next
perforation d in the series will be above the feed opening d and the powder con-
tained therein be forced out, and when the shaft H turns in the opposite direction
the feeding disc in the other hopper will be operated in the same manner.
It will be understood that the number of studs d² in the disc D³ must be the
same as the number of perforations in the feeding disc D¹; each hopper D is
provided with a stirrer, and as the character of the powders in the two hoppers is
different I have provided stirrers of different construction for these two hoppers.
One of them consists simply of curved arms D³ attached to and rotating with the
upper end of the shaft D2 or the upper side of the disc D¹. The stirrer in the other
hopper consists of a post D6, carrying a number of radial rods do, which in succession
operate the blades or vanes of a rotary fan D' journalled to the inside of the hopper,
said post De being attached to and rotating with the disc D¹ therein.
Within the hopper D are two stationary blocks a, c. The block a has a spring x
attached to its under side, and which operates to throw the powder out of the
measuring openings at the proper time as each successively passes under the

page_text: same. To the under side of the block c is hinged a spring i, which is regulated by
the action of a screw g passing downward through the block. When this screw is
driven down it causes the spring i to press down the powder in the registering or
measuring apertures d' as they successively pass under it, and pack the powder
therein more or less according to the distance that the spring is made to project. 5
This makes the powder larger, or rather heavier, because the space which the spring
leaves indented in it is filled up as the disc turns farther round and before it is
discharged.
From the hoppers D the powders pass through the openings d, and drop into
funnels E, E, which are at the top provided with cross bars y, whereon the powder 1
falls and by which it is broken up to descend the tube F with facility. Each funnel
E is attached to the upper end of the tube F, supported by bracket arms G attached
to the rear standard B. On the tube F is placed a sleeve pinion F¹ connected with
the tube by a pawl-and-ratchet device a³, so that when the pinion is rotated in one
direction the tube will turn with it, but will remain stationary when the pinion is 1
rotated in the opposite direction.
The pinions gear with and receive motion from a spur wheel HI' on the vertical
driving shaft H. Each of these pinions has also cogs 1, which engage with and
turn pinions J, J, upon the upper ends of two front and rear vertical shafts K, K,
journalled in the bracket arms G. The front shaft K is provided with two rollers 2
,, and the rear shaft with a similar roller . The lower one of the two front
rollers. is pressed toward the tube F by a spring K' attached to the inner upright
plate A¹.
The lower part of the tube F is surrounded by a rigid cylindrical casing L, leaving
a space between then, the said casing being attached to the lower bracket arm G. 2
The front of the casing L has a slot or opening e to allow the rollers to be pressed
against the tube, and is also provided with a rear opening to allow the roller
to act against it in like manner.
"
The construction and arrangement of these devices is fully shown in Figure 3.
The vertical shaft H is near its lower end provided with a large crown whoel M, :
which meshes with and alternately communicates motion to two opposite pinions m, m,
carried upon the inner ends of two shafts M', journalled in the pairs of upright
plates A, A, at opposite sides of the machine. Each pinion m has attached to it a
spur pinion m, which communicates motion to another pinion n on a similarly
journalled shaft N, and also through a small pinion n', Figure 10, to a larger cog
wheel O that is loose on a shaft P.
The shafts M¹ and N carry rubber-covered rollers M and N¹. The loose wheel O
is provided with a spring catch O', which is adapted to engage with a pin p² on a
toothed wheel P¹, turning with the shaft P, and this engagement is effected just
after a pin on said shaft P is struck by an arm H³ on the upright main shaft.
The wheels P¹ and O then turn together with the shaft P, and the wheel P¹ com-
municates motion to another gear wheel Q' turning with a shaft Q.
The shafts P and Q carry respectively the cam-shaped jaws P and Q, which are
faced with india-rubber or other suitable material. The jaw P is provided with a
transverse metal ridge or blade p³, and the jaw Q with a rubber-filled box or
trough q, adapted to receive the same.
The shaft N outside of the plate A³ carries a small cam R that operates on a pin
on a shaft R', which carries a bent folding bar R and is provided with a coiled
spring R³ that tends to force said folding bar downward toward the rubber. All of
the shafts P, Q, and R¹, are journalled in the plates A¹, A²
The construction, arrangement, and combination of tubes, gearing, and other
devices above described are exactly the same on the two sides of the machine. On
the shaft H is secured a collar H³ provided with two pairs of horns 5, which extend
in opposite directions and operate respectively upon the tails or rear points 8 of two
pivotal diverging jarring arms S so as to alternately withdraw their outer ends or
hammers T from contact with the respective powder-conducting tubes F. As soon
as the tail or points is released by the horn the hammer T on the other end of

page_text: the arm is thrown against its tube by the action of a spring U. These jarring arms
S are pivoted upon the lower bracket G. Their oporation is alternate, and they
serve to loosen any powder which may adhere to the inside of either tube, and thus
prevent the choking of the said tubes.
The powder is further prevented from sticking to the tube by an internal lining 3,
Figure 3, of paper, thin wood, or other suitable material.
The power for operating the machine may be applied directly to the shaft H in
such a manner as to rotate the same first in one direction and then in the other; or
such power may be applied to cranks on the ends of the shafts M', giving the same
an alternately reciprocating rotary motion.
The alkaline and acid powders are placed in different hoppers D, and the paper,
cut to the proper size, is fed to the machine alternately by the right and left hands.
One paper is inserted between the tube F on the right and its front rollers k, k, and
as the machine turns in the proper direction this paper, by the action of the tubo
and rollers, is carried in between the said tube and its sleeve or cylindrical casing L.
By the time a half revolution of the main shaft H is made this paper is rolled
twice around the tube. As soon as this is effected the shafts P and Q are turned
by the action of the arm H³ upon the pin q to make the jaws P and Q² grasp the
paper tightly enough to prevent the escape of powder from the paper.
The shaft H is now reversed, and at the same time another paper is inserted
between the other tube F and its rollers; while this is being done the powder is
deposited in the first paper from the hopper above through the funnel E and tube F
by the devices above described; and as the movement continues the jaws P and Q³
carry the paper down, the bottom thereof being folded up by the action of the
bar R and pass it roughly folded to the rollers, M and N¹. The upper end of the
paper is creased and partly folded by a cross bar V on the roller N¹, and as tho
paper passes between the rollers M² and N¹, it is pressed together, folded, and then
drops through the opening a¹ in the base A, both sides of the machine operating
in the same manner; successive alkaline and acid powders are put up in folded
papers and deposited below the machine.
Figures 12 and 13 illustrates mechanism for working the said machine by
the foot. A*, A*, are two screws goared together by toothed wheels a* on or
near the end of the screw shafts. These shafts arc journalled in the legs or
upright pieces of the stand that supports the machine, and motion is communicated
to them by a treadle attached by a rod to the outside of the balance wheel B*.
A rack C sliding on a transverse bar D* is moved to and fro by the operation of
the said screws, the said rack being connected therewith by a rigid rod E* which
extends down from one end of the rack C*, and engages between the threads of one
of the screws either on the one side or the other; both screws are right handed and
geared together, so as to turn always toward each other, and when the traveller E*
is applied between the threads of one it is carried to the left, and when between the
threads of the other to the right. When the said traveller has passed to the end of
either screw it is transferred to the other by means of the screw thread, which
becomes shallower until it terminates at its surface, as shewn by the dotted lines
in Figure 13. At the time the traveller is being thrust out of one roller by this
shallow part of the groove it is received at the end of the other scrow in a groove
which becomes deeper and deeper until it is of sufficient depth to contain it. The
changing of the said traveller from one screw to the other is prevented, except at
the proper time, by a partition of sheet metal Fo. The under side of the bed plate
of the machine is provided with a segment of a gear wheel attached to the upright
shaft of the machine projecting through and meshing with the teeth of the rack C*.
The above described machine is to be placed upon a table, and the apparatus
shewn in Figures 12 and 13 is placed under the said table.
