EUGEN WOLNER, of Tue brook near Liverpool in the County o
hereby declare the nature of this invention to be as follows:-

This invention relates to that class of machines for which I have already obtained
Letters Patent No. 97783
The weighing table or platform is provided with cross beams, the outer ones of
which are secured at each end to two cross beams, one at each side of platform, having
small shoes at each end, and the whole resting on the knife edges of the machine levers.
These levers are built levers, each limb having the cross section of the letter L, this
form being the best to resist the strains they are required to withstand and are also
easy to mould. The major lever of these consists of the main limb (being in a diagonal
direction and formed with strengthening webs) and the minor limbs, numbers 1 and 2
with stay limbs and hanger shaped ends, which are provided with knife edges, forming
fulcrums. In the pattern for casting, minor limb number 2 is placed centrally between
the knife edges, and rests on the bottom flange of the main limb, and joins minor limb
number 1 on the other side. The limb rests also on bottom flange of the main limb.
The minor limbs are joined by stay limbs in a diagonal direction from the fulcrum
hangers and also by a central stay limb. The minor limbs are in a diagonal direction
to each other and held together by stay limbs, and form a strong beam both to
resist torsional as well as bending strains. The reason why one flange rests on the
other instead of running into the other is that the pattern by this means is stronger
and easier to make, otherwise all the flanges could be in the same plane running into
each other. The minor lever is built up exactly in similar manner and consists of a main
limb, and minor limbs with the stay limbs, and the hanger shaped ends provided with
knife edges forming fulcrums. On the main limb of major lever is a short arm that
is cored out to make room for a coupling link, and on this arm is fitted a muff,
provided within on the bottom side with a knife edge, and this muff is just set in the
desired position and secured by a set screw. In casting, the short arm can be fixed
on the pattern at any desired point on the limb. If this arm is brought low down on
the pattern nearer the hanger, this will suit a shorter machine, and if it is fixed on the

page_text: pattern higher up on the limb, nearer the centre of suspension it will adapt itself to
a longer machine. Again, if the hanger on limb number 1 of major lever, and the
hanger on the limb of minor lever are brought further out to the side by an extension
piece, or brought further in towards the centre by a stopping off piece on the pattern,
the levers will then be adaptable for narrower or wider machines. The main limb of
minor lever can in the same manner be made shorter or longer by a stopping off or an
extension piece for the pattern to meet the position of the short arm on main limb of
major lever. The main limb of minor lever is also made hollow or channeled at its
end to make room for a coupling link, and a muff is fitted on and provided within on
the top side with a knife edge, and set in the desired position and secured by a set
screw. The adjustment of the major and minor levers at their couplings becomes very
easy, as the position of them is on the outside of the platform, and can be got at through
a hand hole in the box neck without disturbing any parts of the weighing machine.
The position of these coupling centres is of course equally distant from the fulcrum
contres of the major and minor levers. The distance between the two coupling centres
is by this arrangement brought down to a minimum which is very important in the
coupling of a pair of levers to ensure sensitive weighing. The form of these lovers
is of advantage on account of leaving the centre space of the machine unoccupied and
allowing the beams which carry the platform with the load to come down in between
them, and also in larger machines they allow a free access down into the pit of the
machine foundations and the whole can be got into a shallow box.
The major lever is carried by its fulcrum knife edges in links hanging in the corner
box brackets of the machine box and is suspended in a shackle by the knife edge in
a muff, which latter is adjustable and secured by set screws, and hooked on to the
suspension rod in the relieving apparatus. The minor lever is suspended by the knife
edge, in another muff, from a coupling link that is again carried by a knife edge in a
muff on the short arm on the main limb of major lever. The link in one corner
bracket is connected by a rod to the link in the opposite corner bracket of the machino
box. The connection of the links by the rod prevents the levers from moving in a
direction opposite to each other, but still allows a simultaneous parallel action to take
place by any side motion of the platform.
The platform with its beams and cross beams at each end of machine will rest on
points of the four corner brackets, when the machine is thrown out of gear.
The platform is made of wood and the central planks are secured to wooden beams
and placed on the main wooden beams. The two outside planks are secured to the
cross beams at overhanging parts. The three exposed sides of the machine box can
also be made of wood and dovetailed into the corner brackets, and plates are let in on
the outside and secured with bolts through brackets. The neck of machine box is of
metal and bolted to the corner brackets, and to the casing of the relieving apparatus.
By this mode of making the box a great deal of metal is saved.
The suspension rod in the indicating apparatus is hooked into a shackle, the latter
carrying a suspension knife edge in the muff on the major lever's main limb. The
suspension rod has at its upper end two lateral projecting shoulders and a shackle.
This latter is hooked up by a hook hanging by a bolt, in the eye of a shackle guard,
which in turn hangs on the shackle suspended from the knife edge on one arm of the
compound lever of the indicating apparatus, where all the transferred power from the
inajor and minor levers is taken up by these means.
The indicating apparatus consists of the before mentioned compound lever or knife
edge working on a suitable frame carrying a sliding weight on one of the arms having
a scale for adjusting said weight and a clamping screw. This weight is used for
weighing off the tare. On the said arm at the extreme end is suspended from the
knife edge, a shackle and suspension rod with a piston in a plunger filled with liquid
and covered with the box cover.
The piston is made up of a number of plates a little apart from each other to allow of
the liquid forming a hydraulic packing. The cover has a hole in its top and bottom
large enough for the suspension rod to pass through plus clearance, and is made in the
form of a box that the fluid in the cover may act like a cushion for the fluid that tries

page_text: to rush up through the bottom hole, and also for the purpose of hindering motion of
the liquid in the plunge box by the working of the piston. The other arm of the
compound lever on the opposite side has a counter-balance weight by which the indica-
ting apparatus is brought to zero, and is also provided with a knife edge fixed at the
same distance from the centre that the knife edge on the opposite arm is. From the
knife edge is also suspended a shackle and suspension rod with a piston in a plunge
box. This latter is filled with fluid (petroleum or other oil preferred) and covered
with a box cover, and in every respect like its fellow plunge box, The one piston in
its plunge box checks undue oscillation of the compound lever in its upward movement,
and the other piston in plunge box acts in a similar manner for the downward
movement.
The arms provided with knife edges constitute the equal beam of the compound
lever.
To ensure the same level of the fluid in the two plunge boxes they are provided with
a tube, with a cock fixed on the side near to the bottom of the two plungers, thus
when the fluid is poured into one plunger, the cock is opened, and the liquid will find
its own level through the tube. The communication is then disconnected if desired by
turning the cock.
When the plunge boxes are to be emptied, the cocks are opened and the fluid runs
out. The liquid in the plunge boxes may be at a high or low level without having any
interfering effect upon the counterpoise weight. Another arm of compound lever going
in a downward direction is at the extreme end provided with a knife, from which
is suspended in a shackle the counterpoise weight. This arm constitutes the pendulous
lever.
An arm going in an upward direction and bolted to the compound lever, carries the
dial on which are a series of scales for the minor weights, and a scale on the edge of
the dial for the major weights. The indication on the dial takes place in following
manner. On one arm of the compound lever is bolted a segment quadrant, on which
is fastened a chain that passes round a helical grooved pulley, working in a bracket fixed
on the carrier frame, bolted on the base frame. The chain is fastened on the middle
of the pulley to prevent it slipping and a weight at the other end keeps the chain
tight. On the inner pivot of tho pulley is fixed a pointer wheel that points to the scales
for the minor weights on a dial and a pointer that is fixed on the casing points to the
scale for the major weights on the edge of the dial.
To bring the machine out and into gear, I make use of the following relieving
apparatus.
A hand lever is fixed on the one end of a spindle working in a bearing bolted on the
base frame, and on the other end is fixed a radial grooved disc. The disc works a second
dise provided with three pins with friction rollers equally distant from each other,
working in the grooves of dise No. 1. The second disc is fixed on the end of a spindle
working in bearings bolted down on the base frame, and has also fixed on the same
spindle in between the bearings, a pinion working into rack guided in the guides, which
are in one with the bearings. In one with the rack is a bracket for the purpose of

up, say as much as an angle of 40 degrees, the grooved disc, turning a disc by pins
with friction rollers to double the amount, that is to 80 degrees, and having the pinion
on the same spindle, lifts the rack, with bracket, till it lifts out the shackle at the
fork part of the suspension rod (that carries the levers etcetera in the weighing machine)
from the hook, and as the shackle is made with a curvature to the one side at the upper
part, it is heavier on that side, and will therefore fall back on to the guard shackle. The
book that is balanced by the ball will fall a little to the side. As the shackle is
unhooked, the compound lever will then be resting by one of its arms in the carrier
frame. By reversing the action of the hand lever, the rack with the suspension rod
resting in the bracket will then be brought down, and the shackle will be guided
forward and down on a guard, but can not fall forward more than projecting parts on
the shackle will allow, as these will rest on the fork part of the rod. The suspension

page_text: rod with the levers will be brought down till the beams in the weighing machine come
down upon the parts of the bracket.
To put the apparatus into gear I repeat the operation and lift the hand lever on
spindle carrying the grooved disc that rotates the second disc on the spindle, and with
it the pinion. This latter works the rack, and thus raising or lifting the same with
the suspension rod in the bracket, till the shackle comes up against the hook. This
being nicely balanced by the ball will be easily pushed upwards and aside till the
shackle has passed the hook. Then the hook will fall back again, and thus cause the
shackle to catch the hook. The hand lever that works the rack is now again brought
down to its original position.
The machine is now connected with the indicating apparatus, the cart is brought
onto the platform, and its weight found by moving the tare weight on the arm of
compound lever; when the tare is ascertained the weight is fixed in its position by the
set screw. The cart now returns loaded on to the platform, and causes the compound
lever to move slowly. The dial on upward arm of compound lever consequently passes
from right to left, and at the same time the pointer wheel turns round, being worked by
the chain round the helical grooved pulley. The major weight is now read off by the
pointer, and the minor weight on the scales on the body of the dial fixed by means of
the pointers of the pointer wheel.

I, EUGEN WÖLNER, of Tue Brook, near Liverpool, in the County of Lancaster, do
hereby declare the nature of this invention and in what manner the same is to be por-
formed, to be particularly described and ascertained in and by the following
statement:-
The invention relates to that class of machinos for which I have already obtained
Letters Patent, No. 97783, and is best described by aid of the accompanying drawing
in two scales.
Figure 1, is a front elevation on the smaller scale of my apparatus.
Figure 2, is a general plan, on the same scale, with half of the platform and the
cover over the lever coupling removed, showing the machine box and lever.
Figures 3 and 4, are respectively a plan and elevation of machine levers.
Figure 5, is a larger scale cross section of lever on the line XX.
Figures 6 and 7, are respectively large scale front section on the line X' X¹ and
end section on the line X2 X2 of Figure 3, of the coupling of the two levers.
Figure 8, is a large scale plan, Figure 9 a side elevation of the weighing machine
itself with half of the platform removed in Figure 8, and Figure 9 is partly in section
following line X3 X³ of Figure 8 and partly in elevation showing lever resting in the
link. Figure 10, is partly a tranverse section and partly an elevation on the line
XX' of Figure 2, showing indicating apparatus and relieving apparatus.
Figure 11, is a sectional end elevation of indicating apparatus on the line X3 X5 of
Figure 2.
Figure 12, is a sectional end elevation of indicating apparatus on the line X X of
Figure 2.
Figures 13, 14, 15, 16, and 17 are respectively elevations and plan of the relieving
apparatus to the larger scale.
In the drawings, A is the weighing table or platform with beams B and B¹, the
former of which are secured at each end to two cross beams B³, Figure 8, one at each
side of platform A having small shoes e at each end, and the whole resting on the knife
odges e of the lever C and C" (Figure 3). The levers C and Care built levers, each
limb having the cross section of the letter L, this form being the best to resist the
strains they require to withstand and easy to mould. The major lever C consisting of
the main limb L being in a diagonal direction with strengthening webs and the
minor limbs L L with the stay limbs L³, L* L' and the hanger shaped ends G which
are provided with knife edges e forming fulcrums. In the pattern for casting, the limb L³
is placed centrally between the Knife edges el e³, and rests on the bottom flange of
limb L, and joins limb L' on the other side. Limb L' rests also on bottom of flango

page_text: of limb L. L' and L³ are joined by the stay limbs L2 and L in a diagonal direction
from the fulcrum hanger G, and also by the central stay limb I. L' is in a diagonal
direction to L³ and held together by the said stay limbs L L and L, and forms a strong
beam both to resist torsional as well as bending strains. The reason why one flange rests
on the other instead of running into the other is that the pattern by this means is stronger
and easier to make, otherwise all the flanges could be in the same plane running into each
other. The minor lever C is built up exactly in similar manner, and consists of the
main limb L, and the minor limbs L L, with the stay limbs L8, Lu, L1, and the
hanger shaped ends G provided with knife edges e forming fulcrums. On limb L of
major lever C is a short arm C that iscored out to make room for the coupling link 10 (*,
Figure 6, and on C is fitted a muff C³ provided within on the bottom side with a
knife edge and this muff C³ is just set in the desired position and secured by the
set screw C, Figure 3. In casting the short arm C can be fixed on the pattern at
any desired point on the limb L. If C is brought low down on the pattern nearer the
hanger G this will suit a shorter machine, and if C is fixed on the pattern higher
up on the limb L nearer the centre of suspension, C", it will adapt itself to a longer
machine. Again, if hanger G on limb L' of major lever C, and hanger G on limb L' of
minor lever C, are brought further out to the side by an extension piece, or brought
further in towards the centre by a stopping off piece on the pattern, the levers Cand C¹
will then be adaptable for a narrower or wider machine. The limb-LⓇ of minor lever C¹¹
can, in the same manner, he made shorter or longer by a stopping off or an extension
piece for the pattern to meet the position of C on limb L of major lever C. The limb L
of minor lever is also made hollow or channeled at C to making room for the coupling
link C, Figure 6, and a muff C2 is fitted on and provided within on the top side with a
knife edgee,and set in the desired position and secured by the set screw 07. The adjustment
of the levers C and Cat the couplings C and C³, Figure 4, becomes very easy as the
position of them is on the outside of the platform A and can be got at through the
hand hole B, Figure 2, of the box neck B without disturbing any parts of the weigh-
ing machine. The position of these coupling centres e and e, Figures 4 and 6, are of
course equally distant from the fulcrum centres e² of the levers C and C. The distance
between the two coupling centres e e, as shown in Figures 6 and 7, is by this arrange-
ment brought down to a minimum, which is very important in the coupling of a pair
of levers to ensure sensitive weighing. The form of these levers is of advantage on
account of leaving the centre space of the machine unoccupied and allowing the beams,
which carry the platform with the load, to come down in between them, and also in
larger machines they allow a free access down into the pit of the machine foundations,
and the whole can consequently be put into a shallow box.
The lever C is carried by its fulcrum knife edges e in the links e, Figures 2 and 8
and 9, hanging in the corner box brackets B³ of the machine box and suspended in
the shackle G, Figures 10 13 and 14, by the knife edge in muff Cu, Figures 10, 2, 3
and 4, which is adjustable and secured by set screws Co, Figure 4, and hooked on to
the suspension rod G², Figures 10 and 13, in the relieving apparatus. The minor
lever C, Figure 3, is suspended by the knife edge es, Figure 6, in muff (2 from the
coupling link C that is again carried by the knife edge e in muff C³ on the short arm C
on the diagonal arm L, Figure 3, of major lever C. The link e³, Figures 8 and 9,
in one corner bracket is connected by a rod e, to the link e, in the opposite corner
bracket of the machine box. The connection of the links e³ by the rod e prevents the
levers C and C₁ from moving in a direction opposite to each other, but still allows a
simultaneous parallel action to take place by any side motion of the platform A.
The platform A, Figures 8 and 9, with beams B and B₁ and cross beams B' at each
end of machine will rest at the points B° of the four corner brackets B when the
machine is thrown out of gear. The platform A is made of wood, and the central
planks P¹ are secured to the wooden beams B' and placed on the main wooden beams B.
The two outside planks P are secured to the cross beams B2 at the overhanging
parts B. The three sides B, Figures 18 and 9, of the machine box can also be made
of wood and dovetailed into the corner brackets B³, and plates Baro let in on the
outside and secured with bolts through the brackets B³. The neck B, Figures 8 and 2,

page_text: of machine box is of metal and bolted to the corner brackets B³, and to the casing of
the relieving apparatus at B". By this mode of making the box a great deal of wood
is saved. The suspension rod G³, Figures 10 and 13, in the indicating apparatus
is hooked into the shackle G¹, the latter carrying the suspension knife edge C,
Figures 3 and 4, in the muff on the major lever's limb L. The suspension
rod G has at its upper end two lateral projecting shoulders and the
shacklo g. This latter is hooked up by the hook hanging by the bottom in tho
eye of shackle guard g', which in turn hangs on the shackle g suspended from the
knife edge h on the arm ³ of the compound lever H of the indicating apparatus,
Figuro 10, where all the transferred power from the levers C and C is taken up by
these means. The indicating apparatus in Figures 10, 11, and 12, is drawn in its
half way position. The indicating apparatus consists of the compound lever Hon
knife edge working on frame F, carrying a sliding weight I on the arm 3 having a
scale for adjusting said weight and a clamping screw i. This weight I is used for
weighing off the tare. On the said arm 13, at the extreme end is suspended from the
knife edge 2, the shackle 93 and suspension rod g with piston K in plunge box J
filled with liquid and covered with the box cover J¹.
1°
The piston K is made up of a number of plates a little apart from each other to
allow the liquid forming a hydraulic packing. The cover J' has a hole in its top and
bottom large enough for the suspension rod g* to pass through, plus clearance, and is
made in the form of a box that the fluid in the cover may act like a cushion for the
fluid that tries to rush up through the bottom hole, and also for the purpose of
hindering motion of the liquid in the plunger box J by the working of the piston K.
The other arm on the opposite side has a counterbalance weight I' by which the
indicating apparatas is brought to zero, and is also provided with a knife edge
fixed at the same distance from ³ that 12 is. From knife edge is aspended the
shackle and suspension rod 9, with piston K in plunge box J. This latter is
filled with fluid (petroleum or other oil preferred) and covered with the box cover J³,
and in every respect like its follow plunge box J. Piston K' in plunge box J' checks
undue oscillation of the compound lever H in its upward movement, and the piston K
in plunge box J acts in a similar manner for the downward movement
The arms and constitute the equal beam of the compound lever H.
To ensure the same level of the fluid in the two plunge boxes J and J2, they aro
provided with a tube T with a cock T' fixed on the side near to the bottom of the two
plungers, thus when the fluid is poured into one plunger the cock T is opened and the
liquid will find its own level through the tube T. The communication is then dis-
connected if desired by turning the cock T'.
When the plunge boxes J and J2 are to be emptied, the cocks T2 and T¹ are
opened, and tho fluid runs out. The liquid in the plunge boxes may bo at a
high or low level without having any interfering effect upon the counterpoiso
weight W. The arm going in a downward direction is at the extreme end
edge h, from which is suspended in the shackle g' the

provided with a knife
counterpoise weight W.
The arm, going in an upward direction, and bolted to the compound lever H,
carries the dial D, on which are a series of scales d, for the minor weights, and
a scale d' on the edge of the dial for the major weights. The indication on the
dial takes place in following manner-On the arm is bolted a segment-
quadrant M, on which is fastened a chain M that passes round a helical grooved
pulley O', working in a bracket S, fixed on the carrier frame F¹, bolted on the
base frame F. The chain M is fastened on the middle of the pulley O' to
prevent it slipping and a weight Q at the other end keeps the chain tight. On
the inner pivot of pulley O' is fixed a pointer wheel O. that points to the scales
for the minor weights on dial D, and a pointer 03, that is fixed on the casing,
points to the scale d for the major weights on the edge of dial D. To bring
the machine out and into gear I make use of the relieving apparatus as shown
to a larger scale in Figures 13, 14, 15, 16, and 17.
A hand lover R is fixed on the one end of spindle R' working in the bearing R²,

page_text: If the
bolted on the frame F and on the other end is fixed a radial grooved disc R³.
The disc R works the disc R provided with three pins with friction rollers 2ª
equally distant from each other, working in the grooves of disc R³. The
disc R is fixed on the end of spindle G³, working in the bearings G* bolted
down on the frame F*, and has also fixed on the same spindle in between the
bearings G, a pinion G working into rack G, guided in the guides G', which
are in one with the bearings G. In one with the rack G is a bracket G for the
purpose of taking the suspension rod G³, at the forked part of the same.
hand lever R be lifted up, say as much as an angle of 40 degrees, the grooved
disc R³ turning disc R4, by the pins with friction rollers to double the amount,
that is to 80 degrees, and having the pinion G on the same spindle G³, it lifts the
rack G, with bracket Gs, till it lifts out the shackle g at the fork part of the
suspension rod G (that carries the lovers, etcetera, in the weighing machine) from
the hook, and as the shackle g is made with a curvature to the one side at the
upper part, it is heavier on that side, and will therefore fall back on the guard
shackle g'. The hook ¹, that is balanced by the ball, will fall a little to the side,
as shewn in Figure 16. As the shackle is unhooked from,, the compound
lever H, Figure 10, will then be resting by its arm in the carrier frame Fl at f
By reversing the action of the hand lever R, Figures 13 to 17, the rack G, with the
suspension rod G' resting in the bracket G, will then be brought down, and the
shackle g will be guided forward and downwards on guard g', as shewn dotted in
Figure 16, but it cannot fall forward more than the projecting parts on the
shackle I will allow, as these will rest on the fork part of the rod G³. The
position of the shackle g is such that its curved and heavier upper part is now
on the opposite side of the centre line of the suspension-rod G2, the greater part
of its weight being to one side of the perpendicular, and therefore it is retained
in its vertical position when lifted by the suspension rod G². The latter with
the levers will be brought down till the beams B in the weighing machine come
down upon the parts B of the brackets B³.
g
To put the apparatus into gear I repeat the operation, and lift the hand lever R
on spindle R carrying the grooved disc R³, that rotates the disc R, on the
spindle G³, and with it the pinion G. This latter works the rack G, and thus
raising or lifting the same with the suspension rod G2, in the bracket G³, till tho
shackle g in its vertical position comes up against the hook . This being nicely
balanced by the ball 72, will be easily pushed upwards and aside without throwing
back the shackle g until the latter has passed the hook. Then the hook
will fall back again to the position shown in Figure 16 and thus cause the
shackle to cutch the book r'. The hand lever 1, that works the rack G, is
now again brought down to its original position as represented in Figures 13 and 10.
The machine is now connected with the indicating apparatus, the cart is brought
on to the platform A, and its weight found by moving the tare weight I,
Figure 10, on the arın ³ when the tare is ascertained, the weight I is fixed in
its position by the set screw i. The cart now returns loaded on to the platform A,
and causes the compound lever H to move slowly. The dial D, on arm 8,
consequently passes from right to left, and at the same time the pointer wheel O
turns round, being worked by the chain M, round the helical grooved pulley O¹.
The major weight is now read off at d¹ by the pointer 02 and the minor weight on
the scales d by means of the pointers of the pointer wheel O.
