Sealed the 11th September 1863, and dated the 12th March 1863.
PROVISIONAL SPECIFICATION left by the said Friederich Buser- Kraushaar
át the Office of the Commissioners of Patents, with his Petition, on the
12th March 1863.
I, FRIEDERICH BUSER-KRAUSHAAR, of Bâle, in the Republic of Switzerland,
and of 2, Thavies Inn, Holborn, in the City of London, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN APPARATUS FOR WINDING,
CLEANING, MEASURING, SORTING, DOUBLING, THROWING, AND REELING SILK, PARTS
OF WHICH IMPROVEMENTS ARE ALSO APPLICABLE TO LIKE MACHINERY FOR SPINNING,
DOUBLING, AND TWISTING COTTON, WOOL, AND OTHER FIBROUS MATERIALS," to be as
follows:-
The first part of my Invention relates to improvements upon and applicable
to machinery and apparatus patented by Rudolph Bodmer as a communication
from me, and dated the Twenty-ninth day of September 1857, No. 2508, and

page_text: consists in certain mechanism for regulating the tension of threads of silk or
other fibrous material when the same is wound onto or off reels, bobbins,
spindles, and such like objects, and for which operations a uniform tension of
the thread is required or desirable. The regulator consists in a bar, rod, or
arbor, one end of which during the winding or other operation rests on or is sup-
ported by the thread or other product, whilst its other end rests in a bearing,
and acts upon the friction apparatus, for instance, of the spindle from which or
on to which the thread is to be wound. The lever end resting on the thread
will by its weight, or if preferred, by a spring acting on it, depress the thread
and cause it to deviate more or less from the direct line. If the thread has a
tendency to unwind too freely from the spindle the thread will become slack
and allow the lever to fall, and at the same time the other end of the lever
will by means of a cam or otherwise bring the spindle to the required extent
into contact with the friction apparatus. If, on the other hand, the thread
requires too much tension or pulling to cause it to unwind sufficiently freely
the thread will become stretched, and the lever thereby raised, whilst the other
end of the lever will act upon and disengage the friction apparatus from the
spindle to the required extent. In case of any obstruction the spindle will by
the same means be entirely disengaged or thrown out of gear, which prevents
the thread breaking. I have various modifications for regulating the tension,
but the one just described is sufficient to explain the principle.
The second part of my Invention relates to machinery or apparatus for
sorting, according to weight, threads of silk of equal lengths, and to deposit
those of equal weight into the same receptacle or compartment. This
machine, although intended chiefly for weighing and sorting silk wound on
bobbins or spools, and which bobbins or spools must first be tared or made of
one uniform weight, can also be used for weighing various products made of
cotton, wool, and other fibrous materials. The weighing instrument is formed
on the lever or weighing-yard principle. The long cam has two hooked arms
to receive the ends of a bobbin, and the end of the short lever is forked, one
prong of the fork being in a line through the axis with the long lever, and
the centre line of the other prong forming an angle from the axis with the
first, and perpendicularly below the first, the ends of these two prongs are
provided with screws, on to which adjustable weights are screwed. The
fulcrum of this weighing instrument is supported on the end of a lever, which
is hinged to and moveable vertically round a stud fixed to an upright bar
bolted to the horizontally revolving platform; a second lever is hinged in a
similar way to the upright bar below the first, and the ends of the two levers
are connected with a link, thus making them a parallelogram. The hooked

page_text: end of the weighing yard reaches to the end of the upper lever, when it is
supported by a catch hinged to the lever and taking into a notch in the
hooked end. The parallelogram, with weighing yard, rests by means of a
roller upon a circular inclined plane, the vertical axis of which is also the axis
of the revolving platform, and when the platform turns round its axis the
parallelogram and weighing yard following the inclined plane will rise and
fall with the same, and owing to the peculiar construction and placement of
the weighing yard and adjustable weights, a certain rise or depression of the
yard will correspond with and indicate a certain weight. When the weighing
yard rests upon the highest part of the inclined plane the hooked ends will
reach through an aperture in the platform, and when in that position a bobbin
is placed upon the arms through a revolving feed apparatus. Supposing the
platform to be surrounded by a box containing two different compartments,
representing as many different weights, the circumference of the inclined
plane or other part of the apparatus may be fitted with ten studs or pegs, one
before or near each compartment, and on the platform with weighing yard
turning round, the catch, taking into the hooked end of the latter, will, by
means of a tumbler-lever striking against the pegs, disengage the catch at
each peg, and at the compartment corresponding with the weight of the
bobbin the yard will rise and the bobbin be thrown into the corresponding
compartment of the receiving box. In order to render the weighing process
more rapid I intend to apply several weighing instruments to the revolving
platform, and the platform will be fitted with a corresponding number of
receiving apertures. With the exception of the placing of the bobbin into
the apertures of the feed plate the whole operation is entirely self-acting.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Friederich Buser-Kraushaar in the Great Seal Patent Office
on the 12th September 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, FRIEDERICH
BUSER-KRAUSHAAR, of Bâle, in the Republic of Switzerland, and of 2, Thavies
Inn, Holborn, in the City of London, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twelfth day of March, in the year of our Lord
One thousand eight hundred and sixty-three, in the twenty-sixth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Friederich Buser-Kraushaar, Her special licence that I, the said

page_text: Friederich Buser-Kraushaar, my executors, administrators, and assigns, or such
others as I, the said Friederich Buser-Kraushaar, my executors, administrators,
and assigns, should at any time agree with, and no others, from time to time
and at all times thereafter during the term therein expressed, should and
lawfully might make, use, exercise, and vend, within the United Kingdom
of Great Britain and Ireland, the Channel Islands, and Isle of Man, an
Invention for "IMPROVEMENTS IN APPARATUS FOR WINDING, CLEANING, MEASURING,
SORTING, DOUBLING, THROWING, AND REELING SILK, PARTS OF WHICH IMPROVEMENTS
ARE ALSO APPLICABLE TO LIKE MACHINERY FOR SPINNING, DOUBLING, AND TWISTING
COTTON, WOOL, AND OTHER FIBROUS MATERIALS," upon the condition (amongst
others) that I, the said Friederich Buser-Kraushaar, my executors or admini-
strators, by an instrument in writing under my, or their, or one of their
hands and seals, should particularly describe and ascertain the nature of
the said Invention, and in what manner the same was to be performed,
and cause the same to be filed in the Great Seal Patent Office within
six calendar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said Friederich Buser-Kraushaar, do hereby
declare the nature of my said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by the
following statement:-
My present Invention relates to improvements upon and applicable to
certain machinery and apparatus patented by Rudolph Bodmer, as a com-
munication from me, the said Letters Patent bearing date the 29th day of
September 1857, No. 2508.
The said improvements consist, firstly, in certain mechanism for regulating
the tension of filaments or threads of silk, cotton, or other fibrous material
when the same are wound upon or off reels, bobbins, spindles, spools, and such
like objects in the various operations of winding, spinning, twisting, and
doubling, and for which and other operations a uniform tension of the thread
is requisite or desirable. This tension regulator consists of a bar, rod, or lever,
one end of which is furnished with a suitable eye, hook, or other guide, through
which the thread passes, and by means of which it is supported by the thread
whose tension is to be regulated, whilst the other end of the bar is joined to,
and forms part of a simple friction apparatus connected with the spindle,
bobbin, or other object from which the thread is wound off, or with the spindle
upon which it is wound, or with both. The regulator resting with one end
upon the thread will by its weight depress it according to the amount of
resistance to be overcome in unwinding it from its spindle, and cause it to

page_text: deviate more or less from the direct line. If therefore an increase or a decrease
in the resistance takes place, the deviation will become smaller or larger, and
the regulator will rise or fall, and thereby decrease or increase the friction
upon the spindles in connection with it. In this manner a constantly uniform
tension of the thread will be maintained. In case of the strain becoming too
great the winding-on spindle will by the same friction apparatus be thrown
out of gear with its driving disc or strap, whereby the breaking of the thread
is prevented.
Secondly, my improvements consist in self-acting or automatical weighing
and sorting machinery or apparatus intended chiefly for weighing and sorting
bobbins or tubes of silk thread of equal lengths. The weighing instrument
itself is made on the lever or weighing yard principle, as in the quadrant
weighing machines usually employed for silk, and an improved construction
of which is shown and described in the Specification of the Letters Patent
above referred to, No. 2508, dated September 29th 1857. In these weighing
instruments the bobbin or tube or skein is suspended from or placed upon the
end of the long lever, causing the same to become depressed more or less
according to the weight of the bobbin or skein, whilst a pointer at the end of
the lever indicates the weight upon the graduated quadrant in deniers or in
other weight. In my new self-acting weighing and sorting machine the
graduated quadrant is dispensed with. The weighing yard is attached to a
parallelogram frame, one arm of which is bolted to and suspended from a
horizontal revolving disc or platform, and the other end of the parallelogram
frame with the weighing end of the yard rests by means of a roller upon a
circular inclined plane, whose highest point may correspond with zero on the
quadrant, and whose lowest point may correspond with the depression which
the weighing yard would assume with the heaviest weight intended to be
placed upon it. The machine is surrounded by a box reaching from the
lowest part of the inclined plane to the highest, and this box is subdivided
into compartments, namely, one for each number of deniers, for instance from
5 deniers upwards. When the end of the weighing yard is in its highest
position a bobbin is dropped through a hole in a feed plate, and an aperture
of the revolving platform upon the forked end of the weighing lever, and as
the platforin turns round, the weighing yard with parallelogram frame will
pass through all the various degrees of inclination from that corresponding
with zero to that corresponding with the largest number of deniers, and at a
point corresponding with the weight of the bobbin, the latter will, by a simple
contrivance to be herein-after described, be thrown into the corresponding
compartment or subsdivision of the box. In order to render the process of

page_text: weighing more rapid, I propose to fit the machine with a number of weighing
yards.
This machine is especially intended for weighing tubes or bobbins of silk,
the empty bobbins or tubes being all made of exactly the same weight; but
I also propose to use such machines for weighing silk, cotton, and other
fibrous material whether on bobbins or in skeins or in other forms, and
likewise other objects which it may be desirable to assort according to
weight.
And in order that my Invention may be more readily understood and
carried into effect, I will now proceed to describe the same, reference being
had to the annexed two Sheets of Drawings, and to the figures and letters
marked thereon:-
In Sheet I., Fig. 1 is a side elevation and Fig. 3 a front view of part of
a doubling frame to which my improved tension regulators are applied, and
in which the regulator is at the same time connected with the stopping
apparatus.
a is the winding-on bobbin placed upon the spindle b, which rests with its
flange upon the friction driving disc c, and is held in its position by the
bearing d' of bracket d. The spindles e, e, e, from which the thread is to be
wound off and transferred to bobbin a, rest with their flanges upon the plat-
form of bracket f, whilst the ends of the spindles pass through the sockets and
reach to the eccentrics g, g, g, which, with lever h and eylet-holder i, form the
tension regulator. The thread indicated in dotted lines in Fig. 1 passes from
spindle through eyelet i, and the eyelet of thread guide of coping motion n
to bobbin a. The thread is kept at a uniform tension by the weight of the
lever or regulator h, whose duty is to cause the spindle e to unwind its thread
in exactly the same ratio as it is wound upon bobbin a. If the disc of
spindle e were to be in full contact with platform f, the friction would cause
the thread to unwind too slowly and increase its tension, whereby the regu-
lator h would be elevated to a certain extent and cause the eccentric 9 to raise
the spindle e from the platform f; but as soon as the disc of spindle e is
raised off the platform f, the friction of the spindle and the tension of the
thread will decrease, and the regulator will fall and again bring the disc of the
spindle e into contact, to a certain extent, with the platform f. It follows that
the friction of the spindle e upon platformf will regulate itself in such a
manner that the tension of the thread must remain uniform, and the regu-
lator h be maintained in the normal position shown in the Drawing. An
efficient tension regulator for each separate thread is particularly desirable
when the threads of several spindles or bobbins, as shown in Fig. 3, are to be

page_text: united and wound upon one winding-on bobbin or spindle, and it is equally
desirable to have a self-acting stopping or disengaging apparatus that will
immediately stop or disengage the winding-on spindle if one of the several
threads runs out or breaks. This disengaging apparatus is connected with
and forms part of the tension regulator, and consists of the shank A¹ bent
parallel with axle k of regulator h, the tumbler weight 1, and rod m. In
the position represented in Figs. 1 & 3, the parts k, l, & m, are at rest, the
centre of gravity of being perpendicular over its axis, whilst the shank k¹,
depressed by the weight of rod m, rests against the projection f¹ of bracket f.
The regulator h being supported in its horizontal position by the tension of
the thread, it is evident that as soon as the thread breaks or runs out the
regulator h will drop into a vertical position and strike with the heel of piece g
against k, and cause the tumbler weight to fall, thereby lifting the bar m,
which will with its knob strike against the flange of spindle 6, and raise the
latter out of contact with the driving disc c.
When the thread is pieced, a
slight pressure upon the knob of rod m will bring the regulator h and
parts & into their former position, and set spindle 6 in motion again.
When a fresh bobbin a is to be placed on the spindle b, the latter is lifted out of
its bearing, and its end placed into the small socket d', shown in dotted lines.
Fig. 2 represents a modification of the tension regulator, by which the
winding-off as well as the winding-on are regulated. The winding-off spindle e
rests with its end upon a socket o of bracket p, and the flange of the spindle
is partly in contact with the platform 9, which hinges in bearing r of
bracket P₁
, whilst its bent ends is supported on the small eccentric h¹ (shown
in dotted lines) of regulator h. This platform moves in opposite direction
to the regulator h, rising against the spindle flange, and increasing the friction
thereon when h falls, and falling and thereby diminishing the friction, when h
is raised by the tension of the thread. The winding-on upon bobbin or tube a
of spindle 6 is regulated as follows:-The movement of the regulator h is, by
means of the lever t and bridle u, communicated to the lever v, which has its
fulcrum at w, and reaches with its upper end to the lower arm of the bell-crank
lever a, whose upper arm again supports a small pin or cylinder in spindle
socket d, and upon which pin the end of the spindle 6 rests. Supposing the
regulator his raised by the thread; the spindle 6 will also be slightly raised,
whereby the friction of the flange of spindle b, upon the driving disc c, will be
diminished, and undue increase of tension on the thread prevented. In
case of an obstruction to the regular unwinding of the thread from bobbin of
spindle e the lever h will rise and lift the spindle 6 entirely out of contact with
driving disc c.

page_text: Fig. 4 represents a modification of my improved tension regulating apparatus
as applied to winding-on spindles and bobbins, similar to those of the throstle:
a is the winding-on bobbin placed over the tube b, through which passes the
spindle c; d is the whirl with head e, in the shape of a conical screw. The
flange b' of tube b is slipped from above between the two plates f, f¹, which
are hinged to the rail g, the lever extending downwards from f is fitted with a
set screw, and the lever extending from f¹ is connected with the bar h, whose
fulcrum is in the foot plate of rail g; the two plates f, f¹, thus form a friction
clutch box which opens when the bar his raised by roller m of lever 1, and
closes when the end of the bell crank lever or bar h is unsupported, thereby
exerting upon the flange a pressure whose maximum is equal to the effect
which the lever h produces through its weight. The thread passes, as shown
in dotted lines, round cylinder o and pulley n, and again round o, through e &
d to bobbin a. The motion communicated to the whirl d by the driving
strap p, upon which it rests, is through the thread likewise communicated
to the bobbin a, and in proportion to the resistance offered by a, more or less
thread will be wound on, and the lever 1, with pulley n and roller m, will
rise and fall. The duty of the regulator is therefore to regulate the resistance
in such a manner that the thread will be wound on exactly at the same rate
as that at which it is given off by the cylinder o. If h were to exert its full
pressure upon b¹, a would wind on more thread than is given off by o, and as
an immediate consequence the tension of the thread would increase, and
through pulley n raise lever and roller m, which latter would support
and relieve h of so much of its weight as is needful for establishing the
equilibrium in the winding on and in the tension of the thread.
Fig. 5, connected with and forming part of Fig. 4, represents a modification
of the tension regulator, suitable when a larger number of threads are to be
joined together and wound upon one spindle or bobbin, and the same figure
also shows the arrangement and connection of the several tension regulators
with the stopping apparatus of the winding-on spindle. The function of the
tension regulator is almost identical with that described with reference to
Fig. 1, although the construction of the several parts is different; 9, 9, 9, are
the several winding-off spindles, the threads from which are to be united and
wound upon the winding-on spindle d, Fig. 4. The spindles rest upon the
small bracket bearings r, r, r, fixed by means of set screws upon a rigid bar
or rod r. The eccentrics for regulating the friction of the spindles 9 upon the
bearings or pedestals r are situated within the brackets r, as seen in section
at A, and are fixed on the elbow arm of lever t, which passes through the
bracket r, and upon the end of which the double eccentric or cam s for the

page_text: stopping apparatus is also fixed. A small cylinder in the socket of bracket r
communicates the motion of the eccentric to the foot of spindle q. The threads.
pass from spindles q, through eyelet of lever t to cylinder o, and then, as already
described, to bobbin a of Fig. 4.
The action of the stopping apparatus is as follows:-In case of too much
tension on the thread of any one of spindles q, the corresponding lever t
will be raised, and one side of the double cam s will lift one arm of the double
lever u and depress the other arm, which latter will bear upon the ring of
wire v, connected with the bell crank lever k, and depressing one arm of
same, cause the other arm, which is toothed on the surface, to come in contact
with the screw e, which will instantly screw itself upon the toothed arm and
thereby raise the whirl d and bobbin a off the driving strap p. The bobbin a
will be thrown out of gear in the same manner if a thread breaks or runs out,
in which case the levert will fall and act upon lever u, with the opposite cam.
It is almost superfluous to remark that this system of tension regulator can be
carried out in various other modifications, for instance, the winding-on spindle
in Fig. 4 might be fitted with a separate regulating lever; and again, if Fig. 4
were intended for the operation of spinning, the regulating lever would be
placed directly before the spindle head. Instead of the gravity of the regu-
lating levers, springs or other means could be employed. This mode of
regulating the tension of threads, although more particularly intended for the
various operations of winding, cleaning, measuring, doubling, spinning and
twisting silk, is applicable for making sewing silk, for making yarn of cotton,
or wool, or other substances, and in fact in all cases where it is desirable to
regulate the tension of thread or other filaments.
In Sheet II., Fig. 6 is an elevation and Fig. 7 a ground plan of part of
my improved self-acting weighing and sorting machine, drawn to a scale of
one-tenth of the natural size; Fig. 8 is an elevation, partly in section, through
line A, B, of Fig. 7 of the weighing apparatus; and Fig. 9 is a ground plan
of part of the same drawn to a scale of one quarter of the natural size. This
weighing and sorting machine is especially arranged for weighing and sorting
bobbins of silk after they have passed through my patent measuring appa-
ratus, in which a uniform length of thread is wound upon each and all the
bobbins, the bobbins or tubes, made in preference of paper or sheet metal
being first "tared." The driving gear and part of the framing are left out.
The revolving platform or turntable 6, see Figs. 6, 7, & 8, revolves round its
vertical axis in a similar manner to a railway turntable, and I prefer to sup-
port it on its inner edge or rim on three or more friction rollers, from one of
which it may receive its motion, which must be perfectly steady and smooth.

page_text: Below is the circular inclined plane c, fixed concentrically with 6, and upon
this incline c runs the guide roller o of the parallelogram d, d, and guides the
latter, which is bolted to b by the bracket h, as it performs it circular course
gradually from the highest point of the incline c to the lowest, and then rapidly
from the lowest again to the highest, in which position it is represented in
Fig. 8, and at the moment when the tube or bobbin, drawn in full size in
Fig. 10, is transferred from the feed plate a to the weighing apparatus.
g
The feed plate a, see Figs. 7 & 8, has a circular opening with radial
notches, in which the bobbins are laid, and it revolves on a fixed plate a¹, with
an opening corresponding with the apertures g in the platform b. The notches
on the outer or internally notched rim are intended to receive the thicker end
of the bobbins, whilst those of the inner or externally notched rim are intended
for the smaller end of the bobbins. From a wheel gearing into this disc
wheel, the latter receives a motion in proportion to that of the platform b, and
in such a manner that each pair of notches with their bobbin, as it reaches
the centre of the aperture 9 in the bottom of the feed plate, falls in with one
of the apertures g in the platform b, as seen in Fig. 8. The weighing yard i,
with its fulcrum at m on the short arm of lever d, has in the bridle p only
little play vertically, and is therefore obliged to follow the movements of the
lever d of parallelogram d, d', h, u. In the position seen in Fig. 8, the yard i
is ready to receive the tube, which at that moment will drop from feed appa-
ratus a, through apperture 9 of platform 6 on to its curved arms, see Fig. 9.
The yard i being in this position at the elevation of zero, the weight of the
bobbin will depress it to its greatest attainable depth, namely, to the bottom
of the slot in bridle p, by which it will be supported. On one of the curved
arms of i a notch is formed, into which the spur of pall n takes; n hinges
at its lower end on a pin in lever d, and whilst the roller u rests upon the
set screw, the pall n will, through lever r, lever q, and bridle q', be main-
tained in that position, but as soon as u becomes disengaged, the pall n,
actuated by the weight of u on the end of lever r, would strike the bobbin out
of the curved arms of i, and into the funnel e, see Fig. 6, if the notch allowed
the spur
to pass. The weight upon the screwed end of the yard i is for the
purpose of regulating the tare, and is the regulating screw for the weight.
If the yard were not supported by lever d, it would, like the yard
of an ordinary quadrant weighing machine, at once assume the incli-
nation corresponding to the weight of the load, and, if furnished with a
graduated quadrant, also indicate the weight; from this it follows that the
yard i will only voluntarily follow the guide frame in its gradual descent till it
arrives at the position corresponding with its load. The curve corresponding

page_text: to the graduated scale of the quadrant of the ordinary weighing machine may
be formed by projecting the incline according to the divisions of the graduated
quadrant, whilst the compartments in the receptacle or box surrounding the
machine may be made uniform in size. Or the inclined plane may be made
with a uniform slope, and the compartments of dimensions corresponding with
the weight and bulk of the bobbins which they are to receive.
Corresponding with these compartments are fixed the set screws x, x, see
Figs. 7 & 8, and the roller u in passing over them will by cach set screw Le
lifted up a little, which causes the pall n to withdraw itself from the notch,
thereby liberating the yard i each time. The yard i however will only then
make use of its liberty, when, as already stated, it arrives at that part of its
course where it will be in equilibrium with its load, when it will have a
tendency to rise, and when, leaving its support at the bottom of slot in bridle P,
it will now bear against the top of the slot. Owing to this trifling alteration of
the position of i in the slot of bridle p, the pall n will, when u has past over
the set screw a, clear the notch with its spur, and throw the bobbin off the
hooked ends of the yard i, and into the funnel e, from whence it will fall into that
compartment of box f corresponding to its weight. The funnel e is attached
to the link t. In order to render the operation of weighing more rapid, the
platform is fitted in this instance with ten weighing apparatus and yards.
The feed-plate a is replenished with bobbins in the same measure as they fall
through the aperture g. It is evident that this machine can be modified to
weigh larger bobbins of silk, cotton, wool, and other fibrous material, as well
as other articles or objects which require sorting by weight.
Having now described the nature of my said Invention, and the manner in
which the same may be carried into effect, I wish it to be understood that I
do not confine or restrict myself to the precise details and arrangements herein-
before described and shewn in the Drawings, but what I do claim as the
Invention to be secured to me by the herein-before in part recited Letters
Patent is,
Firstly, in reference to my improved tension regulating apparatus, the
peculiar mechanism and arrangements for regulating the tension of threads, or
other similar products, when the same are wound upon or unwound from
spindles, bobbins, or other objects, and which mechanism is actuated and regu-
lated by the tension of such thread, and formis part of the stopping or dis-
engaging apparatus, in the manner and for the purposes substantially as
described with reference to Figs. 1, 2, 3, 4, & 5, of Sheet I. of Drawings.
Secondly, in reference to my improved weighing and sorting machine the
application of an inclined plane or guide for the purpose of guiding and sup-

page_text: porting the weighing yard; also the use of a revolving platform to which the
weighing yards are attached; also the peculiar mechanism for discharging
bobbins, cops, and spools, and other objects from the weighing yard, and also
the peculiar arrangement and construction of the feed apparatus, in the
manner and for the purposes substantially as described with reference to
Figs. 6, 7, 8, 9, & 10, of Sheet II. of Drawings.
Thirdly, the application of the weighing and sorting machine as above
described, and its modifications for weighing and sorting coins, letters, and
other articles which require sorting according to their weight.
In witness whereof, I, the said Friederich Buser-Kraushaȧr, have here-
unto set my hand and seal, this Ninth day of September, in the year
of our Lord One thousand eight hundred and sixty-three.
