Improvements in Weighing Apparatus.
I, BENJAMIN JOSEPH BARNARD MILLS, of 23, Southampton Buildings, in the
County of London, Patent Agent, do hereby declare the nature of this invention,
(a communication to me from Edward Ferdinand Wattson, of 134, West 81st
Street, Broker, and Lawson Sandford, of 1, East 39th Street, Secretary, both of the
City, County and State of New York, in the United States of America) to be as
follows:-
=:
The invention has reference to improvements in scales, and particularly to a
spring scale in which the weight of the receptacle placed on the pan or platform
does not influence the ultimate indications of the scale, the scale indicating only
the actual weight of the substance introduced into the receptacle.
The invention consists essentially in a weighing apparatus comprising an
indicating device, a support for the body to be weighed, a connecting rod inter-
mediate of the support and the indicating device and made in two sections slidably.
connected, one of said sections being placed in operative connection with the
indicating device and the other in connection with the support, means for locking
said sections, and a device arranged to engage with said means for locking the
sections to automatically unlock the same when the body is removed from the
scale.
The scale comprises two scale pans supported upon a lever system of any suit-
able construction adapted to impart an upward movement to a rod extending
upwardly into the casing: said system being, in this instance, placed in con-
nection with said rod by links.
This rod is made with two overlapping sections, slidably arranged and connected.
One section is provided with a longitudinal slot at its upper end, through which
passes a bolt of a locking device adapted to lock and unlock the two sections of
the rod, thereby causing the same either to act as a unit, or to permit sliding
motion of one section with respect to the other section. On opposite sides of the
rod section are arranged the two scale springs, having their lower ends attached
to regulating screws for properly adjusting the tension, and their upper ends to a
crosshead which is pivoted to one section, so. that it can turn on the upward move-
ment of the rod to provide for inequalities in the tension of the springs.
The upper end of the rod section is placed in connection with a suitable dial
hand arranged in front of a dial. This connection may be effected by a rack on
the upper end of the section and a pinion on the arbor of the hand. A spring
holds the rack against the pinion. The downward motion of the section is limited
by a stop which is in proper position to return the hand to zero.
The device for locking and unlocking the sections of the rod, in this instance,
is operated from the front of the scale and consists of the beforementioned bolt,
and two cam discs: the one being attached to the section, and the other to the bolt.
By turning the bolt to the right, the overlapping portions of the two sections
are wedged together and vice versa.
When a pitcher, or other receptacle, is placed on the scale pans, while the

page_text: sections are unlocked, the section will move upwardly against the action of the
springs until the weight of the receptacle is compensated for. The bolt is then
turned by hand to fasten the sections together. As before described the sections
move together with the introduction of the liquid, or other matter to be weighed,
and the weight is indicated on the dial. After the removal of the receptacle and
contents, the bolt is turned by suitable means to automatically effect the unlocking
of the sections. Said means consist of a trip connected with a cam, and adapted
to be engaged by a spring pressed pawl attached to the casing.
As the parts move upward, the trip passes the pawl, but on the descent of the
trip, it is engaged by the pawl and turned to effect the separation of the sections.
In practice, the trip is made adjustable by a pin and slot connection with one of
the cams, and the pawl is also adjustably mounted so that the parts can be adjusted
for wear and the release effected as near as possible to the end of the downward
stroke.
If the number of pounds is to be registered, use is made of a counter of any
usual construction, which is operated from the upper' section. In the present
case the units ratchet is adapted to be engaged by gravitating pawls arranged one
above the other on the section. As the pawl's successively engage. the ratchet
wheel, the counter is advanced. In the present instance three pawls are proposed
each of which will advance the counter through two and one half pounds.
To give audible indications of the weights, a sounding device is provided which
may consist of a gong, the hammer of which is vibrated at each pound, or at each
predetermined number of pounds. In the present instance, à wheel is used which
is mounted on the arbor of the dial hand, and provided with four pins adapted to
engage successively with the flexible lever arm of the sounder, and so ring up
cach two and one half pounds.
As the present apparatus is more especially intended for weighing liquids it is
preferred to arrange the scale pans to tilt so as to discharge the spilt liquid, by
pivoting the said pans and overbalancing the same so that when the receptacle is
removed they will turn. To swing the lever system and pans out of the way, the
scale frames may be hinged.
In a modification use is made of but one scale pan, which is of a usual form,
and the lever system of which is, as before, connected to the rods.
The locking device for the two sections of the rod is arranged to be operated by
a spring lever extending to one side of the casing. The spring balances the
weight of the lever and so holds the rod sections unlocked.
After the receptacle is weighed, the lever is depressed and the sections are
locked thereby.
For striking off the pounds a wheel is employed which is provided with a con-
centric series of holes corresponding to the half pounds. Into these holes are
inserted pegs which engage the lever arm of the hammer. In this manner the
gong can be made to successively sound any desired weight. In this instance,
the scale is suspended from overhead rails, so that it can be slid from one faucet to
another. The gong and counter may be omitted- if desired.
In another modification, the platform or pan of the scale is supported on the
ordinary lever system, and the usual rod is pivoted at the opposite end of said
lever system to the platform. A vertical bar is pivoted above its lower end to
the rod, and is provided at its lower portion with a pivotal cross piece. Two coil
springs are secured at one end to the cross piece and at the other end to the bottom
of the scale casing. Another vertical bar is connected with the bar by means
of a bolt and other connections, whereby the two bars may slide independently of
each other, or be tightly united so as to slide together. The rod is connected
to the first bar at a point above the lower end of said bar to insure a vertical and
steady rise and fall of said bar when operated by the rod. The first bar is pro-
vided with a longitudinal slot through which passes an enlarged portion of the
bolt, which, with said slot, form a vertical guide for the movements of the two
bars relatively to each other. A lever is pivoted to the bolt and has a bevelled,

page_text: or cam, inner surface, and a disc is supported on said bolt between the second bar
and lever, and is provided with an outer cam surface "next to and conforming with
that of the lever. The drawing down of the operating arm of the lever will cause
the cam on said lever to ride over the cam-disc and force it backward, and through
it, also force the second bar tightly against the first'bar, so as to hold them firmly
together. When the operating arm of the lever is raised, its cam will be drawn
away from the
disc; and the second bar will be loosened from the first bar; allow-
ing said bars to i
move independently of each other.
The upper end of the second bar is connected with a" rack, which engages with
a pinion secured to the arbor of the indicating hand. The pinion is enclosed in
a casing for protection and the rack passes through a slot in said casing, which
slot serves as a guide for the movement of said rack and to keep it in engagement
with the pinion.
14
A weight is located back of the first bar and enclosed between two vertical guides
of the scale frame. The weight is provided on one edge with a rack, and a spring
latch which is secured to the first-bar.and, when in its normal position, engages
with the rack. The arm of the lever rests against the inner surface of the spring,
and when the lever is turned to force said arm outward, it will be forced out of
engagement with the rack, and the weight will drop.
A spring lever dog has its upper locking arm bearing inward and has at its
lower arm a regulating screw passing, through the frame, and bearing on the outer
surface of said arm. A-nib extends out from the arm, of the, lever and a coil
spring connecting the arm with the: second, bar.serves to, keep said, arm and nib
normally raised. When, however, the second bar is raised, so that the nib is
above the dog, and the arm and its nib lowered, the latter will extend over the
dog. A pin on a movable regulating plate serves as a stop to the inner limit of
the upper, acting arm of the dog.
In order that the indicator hand may be caused to point to the zero mark on the
scale dial, when the second bar lias reached the lowest limit of its course, the follow-
ing mechanism is used. The second bar is provided near its' upper end with a pin
or projection, which extends through a slot in the upper part of the first bar.
Two cross-heads are connected by vertical rods which pass through guides in
the scale case, and said cross heads and rods form a vertically movable frame.
This frame is hung and adjusted by a screw journalled in the top of the casing,
and having rotary, but no longitudinal; movement therein. This screw passes
through and engages with a female screw thread in the upper cross-head. The
lower cross-head passes under the pin. When no weight is on the scale platform
or pan, the second bar will drop by gravity until the pin is stopped by the cross-
head. If the hand does not point to the zero mark on the dial, the
screw should be turned to raise or lower the frame, and consequently, raise or
lower the second bar and the rack, and by it, the pinion and hand, until said hand
points to the zero mark on the dial. If it then be desired to weigh any liquid or
other material, the arm of the lever must first be raised; the receptacle for holding
the material is then placed on the pan or platform. The weight of said receptacle
will, through the system of levers, raise the rod and the first bar against the action
of the springs, and, also through the spring catch' and the rack, raise the weight,
which forms a counter balance for the second bar and its rack. The two bars not.
being yet bound together, the second bar and its rack will not be affected, and the
indicator will not be moved. The arm of the lever is then drawn down, so that
the two bars are locked together by the cams, the nib extending over the operating
end of the dog. The drawing down of the arm raises the arm of the lever and
disengages the spring catch from the rack and the counter weight will fall. The
liquid or other material is then put in the receptacle, and its weight will cause
the rod and the bars and rack to rise, turning the pinion and the hand, which will
indicate on the dial the weight of the material in the receptacle, but not the
weight of said receptacle. When all weight or pressure has been removed from
the platform, the bars will drop, their downward movement being assisted by
1

page_text: the springs, and when the nib strikes the upper end of the dog, the second bar
still descending, the nib and the arm of the lever will be forced to rise. As here-
inbefore stated, the screw, plate and pin on said plate, are for the purpose of
adjusting the free operating end of the lever, so as to bring said end under the
nib when the arm of the lever has been drawn down.
It is evident that the invention can be embodied in many different forms of
scales, therefore, I do not wish to restrict myself to the forms described, or to the
details of construction involved.

Improvements in Weighing Apparatus.
1, BENJAMIN JOSEPH BARNARD MILLS, of 23, Southampton Buildings, in the
County of London, Patent Agent, do hereby declare the nature of this invention,
(a communication to me from Edward Ferdinand Wattson, of 134, West 81st
Street, Broker, and Lawson Sandford, of 1, East 39th Street, Secretary, both of the
City, County and State of New York in the United States of America), and in what
manner the same is to be performed to be particularly described and ascertained
in and by the following statement:―
The invention has reference to improvements in scales, and particularly to a
spring scale in which the weight of the receptacle placed on the pan or platform
does not influence the ultimate indications of the scale, the scale indicating only
the actual weight of the substance introduced into the receptacle.
The invention consists, essentially, in a weighing apparatus comprising an
indicating device, a support for the body to be weighed, a connecting rod inter-
mediate of the support and the indicating device, and made in two sections slid-
ably connected, one of said sections being placed in operative connection with the
indicating device and the other in connection with the support, means for locking
said sections, and a device arranged to engage with said means for locking the
sections to automatically unlock the same when the body is removed from the
scale.
The nature of the invention will best be understood when described in con-
nection with the accompanying drawings, in which :-

page_text: יסי
Fig. 14 is a section through the line 14-14 Fig. 12.
Fig. 15 is an enlarged detail view of the upper part of the scale that bears the
indicating device.
Fig. 10 is a partial section on the line 16-16 Fig. 15.
Similar letters and numerals of reference designate corresponding parts through-
out the several views of the drawings.
Referring at present to Figures 1 to 4, the letters a, a designate two scale-pans
supported upon a lever system A of any suitable construction, adapted to impart
an upward movement to a rod extending upwardly into the casing U, said system
being in this instance placed in connection with said rod by links j and j¹. This
rod is made with two overlapping Sections 1 and 2, slidably arranged and con-
nected. The section 2 is provided with a longitudinal slot 3, Figure 3, at its
upper end, through which passes the bolt 4 of a locking device D, adapted to
lock and unlock the two sections of the rod, thereby causing the same either to act
as a unit or to permit sliding motion of the Section 2 with respect to the Section 1.
On opposite sides of rods Section 2 are arranged the two scale springs ss having
their lower ends attached to regulating screws 5 5 for properly adjusting the tension
and their upper ends to a cross head 6, which is pivoted at 7 to the Section 2, so
that it can turn on the upward movement of the rod to provide for inequalities
in the tension of the springs.
The upper end of the rod Section 1 is placed in connection with a suitable dial
hand 8, arranged in front of a dial 9. This connection may be effected by a rack
10 on the upper end of the Section 1 and a pinion 11 on the arbor of the hand.
A spring holds the rack against the pinion. The downward motion of the
Section is limited by a stop d, which is in proper position to return the hand to
zero. The device I for locking and unlocking the Sections 1 and 2 of the rod 13,
is in this instance shown as operated from the front of the scale and to consist
of the beforementioned bolt 4 and two cam discs 12 and 13, the one being attached
to the Section 1 and the other to the bolt 4, Fig. 6. By turning the bolt to the
right the overlapping portions of the two sections are wedged together, and vice
versa.
When a pitcher or other receptacle is placed on the scale pans while the Sec-
tions 1 and 2 are unlocked, the Section 2 will move upwardly against the action of
the springs ss until the weight of the receptacle is compensated for. The bolt 4
is then turned by hand to fasten the Sections 1 and 2 together. As before de-
scribed, the Sections 1 and 2 move together with the introduction of the liquid or
other matter to be weighed, and the weight is indicated on the dial. After the
removal of the receptacle and contents the bolt 4 is turned by suitable means to
automatically effect the unlocking of the sections. Said means consist of a
trip 14, connected with the cam 13 and adapted to be engaged by a spring pressed
pawl 15, attached to the casing. As the parts move upward the trip 14 passes
the pawl; but on the descent of the trip it is engaged by the pawl and turned to
effect the separation of the sections. In practice the trip is made adjustable by
a pin 16 and slot connection with one of the cams and the pawl is also adjustably
mounted so that the parts can be adjusted for wear and the release effected as
near as possible to the end of the downward stroke.
If the number of pounds is to be registered, use is made of a counter of any
usual construction, which is operated from the upper Section 1. In the present
example the units ratchet 17 is shown adapted to be engaged by gravitating
pawls e, arranged one above the other on the Section 1. As the pawls successively
engage the ratchet wheel 17 the counter is advanced. In the present instance
three pawls are shown each of which will advance the counter through two and
one half pounds.
To give audible indications of the weights, a sounding device is provided, which
may consist of a gong F¹, the hammer 20 of which is vibrated at each pound or at
each predetermined number of pounds. In the present instance a wheel 21 is shown

page_text: mounted on the arbor of the dial hand and provided with four pins 22, adapted to
engage successively with the flexible lever arm 23 of the sounder, and so ring up
each two and one half pounds.
As the present apparatus is more especially intended for weighing liquids it is
preferred to arrange the scale pans to tilt so as to discharge the spilled liquid by
pivoting the said pans, as at 18, Fig. 3, and overbalancing the same, so that when
the receptacle is removed they will turn to the position shown by dotted lines in
Fig. 3. To swing the lever system and pans out of the way, the scale frames ()
and may be hinged as at 19.

In the construction shown in Figures 7, 8 and 9, the same principle is embodied,
differences being, merely in the details of construction. Use is made of but one
scale pan a', which is of a usual form and the lever system of which is, as before,
connected to the rods 1, 2. The locking device D¹for the two Sections 1, 2 of the
rod is arranged, to be operated by a spring lever 30, extending to one side of the
casing C. The spring balances the weight of the lever, and, so holds the rod
sections unlocked. After the receptacle is weighed the lever is depressed and
the sections are locked thereby. For striking off the pounds a wheel H is employed
provided with a concentric series, of holes 26, corresponding to the half pounds.
Into these holes are inserted pegs 27, which engage the lever arm 23 of the
hammer. In this manner the gong can be made to successively sound any desired
weight. The scale is also in this instance shown suspended from overhead rails I.
so that it can be slid from one faucet to another. The gong and counter may be
omitted, if desired.
Referring now to Figures 10 to 16 for a description of another modification, the
letter A is the platform or pan of the scale, supported on the ordinary lever
system B, and C is the usual rod pivoted at the opposite end of said lever system
to the platform A. D is a vertical bar pivoted above its lower end to the bar C
and provided at its lower portion with a pivotal cross piece a. E are two coil
springs secured at one end to the cross piece a and at the other end to the bottom of
the scale casing. F is a vertical bar connected with the bar I by means of a bolt
and other. connections, whereby the two bars D. and F may slide independently
of each other, or be tightly united so as to slide together. The rod C is connected
to the bar I) at a point above the lower end of said bar to insure a vertical and
steady rise and fall of said bar when operated by the rod C. The bar 1) is pro-
vided with a longitudinal slot b through which passes an enlarged portion
the bolt G, which with said slot, form a vertical guide for the movements of the
two rods D and F relatively to each other. H is a lever pivoted to the bolt G and
having a bevelled, or cam inner surface d, and I is a disc supported on said bolt
between the bar and lever H, and provided with an outer cam surface next to
and conforming with that of the lever H (see Fig. 14). The drawing down of the
operating arme of the lever H will cause the cam d on said lever to ride over
the cam disc I and force it backward and through it, also force the bar F tightly
against the bar D, so as to hold them firmly together. When the operating arm e
of the lever H is raised, its càm will be drawn away from the disc I, and the bar
will be loosened from the bar D, allowing said bars to move independently of each
other.
of
The upper end of the bar F is connected with a rack J, which engages with a
pinion K secured to the arbor f of the indicating hand L. The pinion K is en-
closed in a casing M for protection, and the rack J passes through a slot in said
casing, which slot serves as a guide for the movement of said rack and to keep
it in engagement with the pinion K. N is a weight located back of the bar D
and enclosed between two vertical guides h h of the scale frame. The weight N is
provided on one edge with a rack 2, and a spring latch which is secured to the
bar D and, when in its normal position, engages with the rack. The arm k of
the lever H rests against the inner surface of the spring ; and when the lever is
turned to force said arm k outward, it will be forced out of engagement with the
rack i, and the weight N will.drop.

page_text: O is a spring lever dog, having its upper locking arm bearing inward and having
at its lower arm a regulating screw'm passing through the frame and bearing on
the outer surface of said arm 7. A nib 'n extends out from the arm e of lever H,
and a coil spring o connecting the arm e with the bar F serves to keep said arm
and nib normally raised. When, however, the bar F is raised, so that the nib n
is above the dog O, and the arm e and its nib n lowered, the latter will extend
over the dog 0. A pin p on a movable, regulating plate q serves as a stop-to the
inner limit of the upper acting, arm of the dog O...
"
+
In order that the indicator hand L may be caused to point to the zero mark on
the scale dial, as for example ŕ in Fig. 10, when the bai F has reached the lowest
limit of its course, the following mechanism is used. The bar -F is provided near
its upper end with a pin or projection -s, which extends through a slott in the
upper part of the bar D. P and Q are two cross heads connected by vertical rods u
which pass through guides in the scale case, and said cross heads and rods
form a vertically movable frame. This frame is hung and adjusted by a screw
journalled in the top of the casing, and having rotary, but no longitudinal, move-
nient therein. This screw passes through and engages with a female screw thread
in the upper cross-head P. "The lower cross-head Q passes under the pin's. When
no weight is on the scale platform or pan, the bar F will drop by gravity until the
pin is stopped by the cross-head Q. If the hand L does not point to the zero
mark on the dial, the screw R should be turned to raise or lower the frame P, Q, u,
and consequently, raise or lower the bar F and the rack J, and by it, the pinion K
and hand L, until said hand points to the zero mark on the dial. If it then be
desired to weigh any liquid or other material, the arm e of the lever H must first
be raised, as shown in full lines in Figures 10; 12 and 13; the receptacle for hold-
ing the material is then placed on the pan or platform A. The weight of 'said
receptacle will, through the system of levers B, raise the rod C and the 'bar ])
against the action of the springs E, and also through the spring catch j and rack i,
raise the weight N, which forms a counter balance for the bar F and its rack J.
The two bars D and F, not being yet bound together, the bar F and its rack J
will not be affected, and the indicator will not be moved. The arm e of the
lever H is then drawn down, as shown in dotted lines in Fig. 12, so that the two
bars D and F are locked together by the, cams d I, the nib q.extending over the
operating end of the dog O. The drawing down of the arm e raises. the arm k.
of lever H and disengages the spring catch j from the rack and the counter
weight N will fall. The liquid or other material is then put in the receptacle,
and its weight will cause the rod C. and the bars D and F and rack J to rise, turn-
ing the pinion K and the hand L, which will indicate on the dial the weight of
the material in the receptacle, but not the weight of said receptacle. When all
weight or pressure: has been removed from the platform A, the bars.DF will
drop, their downward movement being assisted by the springs E, and when the
nib strikes the upper end of the dog O; the bar F still descending, the nib
and the arme of the lever I will be forced to rise, and will assume the position
shown in full lines in Fig. 12, the spring n assisting in restoring the lever H to
such position. As hereinbefore stated, the screw m, plate q, and pin pon said
plate, are for the purpose of adjusting the free operating end of the lever O, so as
to bring said end under the nib n when the arm e of lever h, has been drawn
down.
It is evident that the invention can be embodied in many different forms of
scales, therefore, I do not wish to restrict myself to the forms described and shown,
