IMPROVEMENTS IN TABLE OR COUNTER WEIGHING MACHINES
Year: 1885

page_text: I, WILLIAM BEILBY AVERY of 12 Digbeth, Birmingham in the County of
Warwick, Machine Maker do hereby declare the nature of my invention for
IMPROVEMENTS IN TABLE OR COUNTER WEIGHING MACHINES to be as follows:-
The object of the present invention is more particularly to provide a platform
weighing machine of a size and character suitable for the table or counter which
shall be simple and strong in construction and weigh accurately and which shall
afford facilities for preventing the weights or weighing mechanism being tampered
with by unauthorized persons.
A machine constructed according to my invention requires no loose scale pan,
nor any projections interfering with free access to the weighing platform or table
from any side thereof and such a machine is therefore of great use for weighing
out rapidly a great number of parcels or batches of goods of uniform weight and
is especially adapted for weighing out the dough for loaves in bakeries occupying as
it does but little space and being strong and self contained. This improved
machine moreover prevents dirt and particles of the materials to be weighed from
accumulating on the weights and rendering them inaccurate.
The machine consists of a pair of horizontal lever frames coupled together by a
cross bar and side links working on knife edges the upper frame being fulcrummed
on knife edges resting on bearings carried by standards secured to the bottom of a
shallow box or case and the lower lever frame having its fulcrum in knife edges
bearing against a pair of links detachably connected to the bottom of the said case.
The upper and lower frames each carry a pair of knife edges for the reception
of four bearing blocks on the underside of the detachable top of the box or case
which detachable top constitutes the weighing platform or scale pan; and the
upper and lower lever frames are so combined as to maintain the said platform
or scale as it rises and falls in a position strictly parallel to the base of the box
or case.
The platform or table scale pan has flanges, projections or recesses at or in its
lower side edges by which its detachment can be prevented without interfering
with the legitimate use of the machine and the weights are adapted to be carried
by a frame or stirrup suspended on knife edges towards one end of the upper lever
frane within the case; or a balance weight is arranged to slide on a steelyard

page_text: lying wholly within the case or mechanically connected with a part of the upper
lever frame projecting through a slot in the said case or the lower lever frame can
be extended through an opening in the side of box and actuate a steelyard running
parallel with the side of the box or case and preferably enclosed by a covering or
protecting case or cage of glass, wood or metal adapted to be fixed and locked to
the outside of the main box or case.
By this means the scale can be readily adjusted to weigh out parcels or packages
of any required weight say batches of dough of 2 or 4 lbs each, and the scale
when thus adjusted cannot easily be tampered with by unauthorized persons while
it can easily be altered by the owner or master to weigh out other goods in
parcels of greater or less weight whenever required.
When a steelyard is used working against the side of the main box or case one
member of the compound lever frame is prolonged and works through a slot in the
side of the said case, the steelyard being fulcrummed by a link and knife edge
taking its bearing near the bottom of case, and being supported by a link and
knife edges from the end of the prolonged member of the upper lever frame. Two
sliding weights are arranged on this steelyard the one allowing weights of 10 tbs
or more to be recorded and the other serving to record fractions of a lb.
The whole apparatus is extremely simple strong, compact and self contained, by
which I mean that it carries its weights within it or close alongside and has none
of the working parts detachable when in use.
Such a machine is very suitable for weighing coals in store and may be made of
any suitable size and capacity.

page_text: Improvements in Table or Counter Weighing Machines.
I, WILLIAM BEILBY AVERY of 12 Digbeth Birmingham in the County of
Warwick, Machine Maker do hereby declare the nature of my invention for
IMPROVEMENTS IN TABLE OR COUNTER WEIGHING MACHINES and in what manner
the same is to be performed, to be particularly described and ascertained in and by
the following statement :-
This invention relates to certain improvements in the construction and arrange-
ment of what are known as Table Scales or counter weighing machines, the object
in view being to produce a compact machine which shall be simple and strong in
construction and weigh accurately, and which shall afford facilities for preventing
tho weights or adjustable weighing mechanism from being tampered with by
unauthorized persons.
According to my invention I construct a machine which is quite solf contained,
which does not require any loose scale pan and has no objectionable and unnecessary
projections interfering with free access to the weighing platform or table from any
side thereof, and such machine is therefore well suited for weighing out rapidly a
great number of parcels or batches of goods of uniform weight, and is especially
adapted for weighing out the dough for loaves in bakeries.
The nature of my several improvements will be understood on reference to the
accompanying Drawings.
Fig. 1 is a plan view showing the construction and arrangement of the machine,
with the weighing mechanism and the weight or weights all situate within a
shallow box or case, the weighing platform or table, constituting the cover of the
box or case, being removed.
Fig. 2 is a sectional side elevation on the line 1-2 of Fig. 1 with the weighing
platform or table in place.
Fig. 3 is a section of a machine similar in character to that shown in Fig. 1 but
fitted with means for rendering the weighing platform or table, constituting the
cover, non-detachable; and
Fig. 4 is an elevation of the same as seen from the left hand of Fig. 3.
Fig. 5 is a plan view of a table scale constructed according to my invention in
which the internally suspended weight shown in Figs. 1, 2 and 3, is replaced by a
steelyard situate close to one side of the box or casing, the weighing platform or
cover being removed to show the underlying parts.
Fig. 6 is a front elevation of this machine.
Fig 7 is a vertical section of the line 1-2 of Fig. 5, and
Fig. 8 is an end view of the steelyard and its connections, as seen from the left
hand of Fig. 5.
In all the figures the same letters of reference are used to indicate corresponding
parts.
Referring now more particularly to Figs. 1, 2 and 3, it will be seen that the
internal weighing mechanism consists of a pair of horizontal lever frames A A'
coupled together by a cross bar B, and side links or cheeks B¹ B' in which are

page_text: bearings working on knife edges fixed in the upper and lower frames
respectively. The upper frame A is fulcrummed on knife edges a resting in
bearings carried by standards C secured to the bottom of a shallow box or
case D, and the lower lever frame A' has its fulcrum in knife edges e fixed therein,
which edges hear against a pair of links E E detachably connected to the bottom
of the said casc.
The upper and lower frames A A³ each carry a pair of knife edef ff for
the reception of four hearing blocks on the underside of the framework of the
cover, F, of the box or case, which cover, F, constitutes the weighing platform or
scale plate and the upper and lower lever frames are combined and arranged as
clearly shown in the drawings, so as to maintain the said platform or cover, as it
rises and falls, in a position strictly parallel to the base of the box or case.
G is a frame or stirrup intended to receive the weight or weights, and provided
with cheeks or straps in which are bearings adapted to rest on knife edges g. 9
fixed in the upper lever frame A. To facilitate the insertion and removal of the
weight frame a slot is formed in one or both of the checks in which are the
bearing surfaces, and covering plates are secured to the inside of the cheeks or
straps to prevent the displacement of the stirrup and weights when in use.
Rising centrally from the stirrup G is a vertical pin H for the reception of the
weight I which is contrally perforated.
The weight of the stirrup G is such that when in place it will just balance the
weighing platform or cover F, whether said cover be in one with the framework
which rests on the edges ffff" as in Figs. 3 and 4, or whether it consists of a
scale plate resting on, but separate from, the framework which rests on the said
edges within the box D.
The scale represented in Figs. 3 and 4 is one especially designed for use in
bakeries, and the weights more usually required will therefore be those of 2 lbs.
and 4 lbs. respectively; and a 2 lb. weight is indicated in these figures of the
Drawings, in position upon the stirrup G.
To enable the baker readily to ascertain when the scale is in balance I provide
as an indicator, an extension A³ of the upper frame A, which plays through a slot
in the side of the box or case and by its position indicates whether the full weight
is on the scale plate or cover.
To prevent as far as possible dirt from entering the case and rendering inaccurate
the balance, I preferably form the cover with deep flanges all round, and to prevent
any tampering with the weight which has been placed in position within the case D
I provide the cover on its underside with slotted lugs and pass a locking pin or
bolt K through the slotted lugs and through holes in opposite sides of the case,
as clearly shown in Figs. 3 and 4. The slots in the lugs are of a length to permit
the free movement up and down of the scale plate or cover, and slots are provided
in the flanged edge of the said plate or cover at those points where the extension A'
and locking pin protrude.
I secure the locking pin in place by a padlock k. For some trades requiring the
weights to be frequently changed it is undesirable to have the cover non-detachable,
and in that case I may use a separate scale pan or plate which meroly rests on the
framework supported on knife edgesƒƒƒƒ¹ within the case; see Fig. 2. The
- internal weighing mechanism however remains as before, as does also the
indicator A*. The position and form of the indicator may vary, and the vertical
flange of the separate scale pan or plate may be dispensed with.
A self contained weighing machine of this kind, and more especially of the
pattern represented in Figs. 3 and 4, when made on a larger scale, is very useful
for rapidly weighing out sacks of coal in coal stores, and for similar purposes.
Referring now to Figs. 5 to 8 inclusive it will be seen that the internal weighing
mechanism, that is to say the compound lever movement, is the same as that above
described with reference to Figs. 1, 2 and 3.
The weighing platform or cover is also substantially the same as that shown in
Figs. 3 and 4 and is similarly mounted, but the means for preventing its detach-

page_text: ment are not required, for the weights in this machine are not suspended on a
hanging frame or stirrup within the box or case, but a steelyard and sliding
weights are adapted to the outside of the box or case below the level of the cover
and are connected with the compound lever movement within the case through an
extension of the upper lover frame A similar to that used as an indicator in the
foregoing examples, which extension may therefore be lettered A'.
The end of this extension piece A' is forked to carry a knife edge / on which
hangs a shackle or link m united by a loop or eye with a second shackle or link n
which supports a knife-edge o fast in the steelyard L. This steelyard is fulcrummed
at o on a knife edge held down by a shackle or link p which is loosely mounted
on a pivot pin q projecting from the case D, all of which parts are clearly
represented in Figs. 5 to 8 inclusive.
The steelyard is fitted with sliding weights M N, the larger weight M fitting
loosely on the steelyard and having a knob or handle for shifting it to its proper
position and a fixed pawl or tooth adapted to be dropped into ono of a series of
notches in the steelyard, for holding the weight in place; and the smaller weight N
sliding on the front of the steelyard and indicating the fractions of a lb, or other
known standard of weight.
I would remark that the steelyard might be enclosed by a covering or protecting
case of glass, wood or metal, adapted to be fixed and locked to the outside of the
main box or case and in this case the weighing platform or cover of the machine
would also be rendered non-detachable by a locking pin and lugs as shown in
Figs. 3 and 4.
A clamping screw or equivalent device would also be fitted to the sliding
weights M and N so that they could be locked or clamped upon the steelyard so as
to balance and indicate a certain definite weight of goods such as 2 lbs. or 4 lbs.
placed on the scale, pan, platform or cover, but it has not been thought necessary
to show such arrangements in Figs. 5, 6, 7 and 8, of the Drawings.
The steelyard with non-detachable pivotted weight capable of being rapidly set
in one or other of two positions, as described in the specification of my invention
for which I obtained Letters Patent dated 26th February 1885 N° 2634, might
also be employed in lieu of the steelyard and weights represented in Figs. 5 and 6 ;
in combination with a compound lover similar to that hereinabove described and
shown in the Drawings, but it has not been deemed necessary to illustrate this
combination.
I would observe that in the present application for Letters Patent I make no
claim to any novelty in the steelyard per se, nor to novelty in the location of a
steelyard outside the case containing the compound lever movement, neither do I
intend to make any claim to the use per se of a compensating mechanism which will
preserve the scale pan in a perfectly horizontal position, nor for enclosing the
weighing levers in a box or case, as these arrangements have been common to the
trade for upwards of 30 years neither do I claim anything claimed in or covered by
the specification of Beranger's patent dated March 19th 1849 No. 12525; but :-
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
1. The construction and arrangement of the several table or counter_weighing
machines hereinabove described with reference to the accompanying Drawings,
whereby I secure simplicity, strength and economy of space.
2. The combination with a shallow_box or case as D, and a movable weighing
platform, scale plate or cover such as F, of a compound lever constructed arranged
and operating as described with reference to the Drawings for supporting and
maintaining the horizontality of the cover, during the weighing operation.
3. The combination with the box or case D and weighing platform or cover F,
of the compound lever arranged within the case and comprising the upper and
lower frames A A³, cross bar B, side links or cheeks B' B' and appropriate bearings

page_text: and knife edges; one of the members of the said compound lever being prolonged
to play through a slot in the case below the said cover and serving as an index
when the weights are carried within the case, or as a means for transmitting
motion to a steelyard arranged outside the case, substantially as set forth.
4. The combination with a shallow box or case as D, movable weighing platform
or cover F and a compound lever arranged within the box or case to carry the
said cover and maintain its horizontality in action, of a hanging frame or stirrup
such as G carried by the compound lever and adapted to receive a weight or
weights, as and for the purpose described with reference to Figs. 1 to 4 inclusive.
5. The construction and arrangement of weighing machine or table scale described
with reference to Figs. 3 and 4 of the Drawings in which machine the weights
are slung or carried entirely within the case, and means are provided for preventing,
when necessary, access to the interior of the case by the removal of the weighing
platform or cover, substantially as and for the purpose set forth.
6. The combination with a box or case D and a steelyard mounted as described
alongside the said case, of a movable weighing platform constituting a cover for
the case, a compound lever frame constructed, arranged and operating as described,
within the said case, and connections for transmitting the movements of the
compound lever to the said steelyard, all substantially as and for the purpose
described with reference to Figs. 5 to 8 inclusive of the Drawings.

page_text: I, WILLIAM BEILBY AVERY of 12 Digbeth Birmingham in the County of

This invention relates to certain improvements in the construction and arrange-
ment of what are known as Table Scales or counter weighing machines, the object
in view being to produce a compact machine which shall be simple and strong in

projections interfering with free access to the weighing platform or table from any
side thereof, and such machine is therefore well suited for weighing out rapidly a
great number of parcels or batches of goods of uniform weight, and is especially
adapted for weighing out the dough for loaves in bakeries.
The nature of my several improvements will be understood on reference to the
accompanying Drawings.
Fig. 1 is a plan view showing the construction and arrangement of the machine,
with the weighing mechanism and the weight or weights all situate within a
shallow box or case, the weighing platform or table, constituting the cover of the

Fig. 2 is a sectional side elevation on the line 1-2 of Fig. 1 with the weighing

Fig. 3 is a section of a machine similar in character to that shown in Fig. 1 but

cover, non-detachable; and
Fig. 4 is an elevation of the same as seen from the left hand of Fig. 3.
Fig. 5 is a plan view of a table scale constructed according to my invention in
which the internally suspended weight shown in Figs. 1, 2 and 3, is replaced by a
steelyard situate close to one side of the box or casing, the weighing platform or
cover being removed to show the underlying parts.
Fig. 6 is a front elevation of this machine.
Fig. 7 is a vertical section on the line 1-2 of Fig. 5, and
Fig. 8 is an end view of the steelyard and its connections, as seen from the left
hand of Fig. 5.
In all the figures the same letters of reference are used to indicate corresponding
parts.
. Referring now more particularly to Figs. 1, 2 and 3, it will be seen that the
internal weighing mechanism consists of a pair of horizontal lever frames A A'
coupled together by a cross bar B, and side links or cheeks B' B' in which are

page_text: bearings working on knife edges b' fixed in the upper and lower frames
respectively. The upper frame A is fulcrummed on knife edges a resting in
bearings c carried by standards C secured to the bottom of a shallow box or
case D, and the lower lever frane A¹ has its fulcrum in knife edges e fixed therein,
which edges bear against a pair of links E E detachably connected to the bottom
of the said case.
The upper and lower frames A A' each carry a pair of knife edges ff, f¹ƒ³, for
the reception of four bearing blocks on the underside of the framework of the
cover, F, of the box or case, which cover, F, constitutes the weighing platform or
scale plate; and the upper and lower lever frames are combined and arranged as
clearly shown in the drawings, so as to maintain the said platform or cover, as it
rises and falls, in a position strictly parallel to the base of the box or case.
G is a frame or stirrup intended to receive the weight or weights, and provided
with cheeks or straps in which are bearings adapted to rest on knife edges g g
fixed in the upper lever frame A. To facilitate the insertion and removal of the
weight frame a slot is formed in one or both of the cheeks in which are the
bearing surfaces, and covering plates h h are secured to the inside of the cheeks or
straps to prevent the displacement of the stirrup and weights when in use.
Rising centrally from the stirrup G is a vertical pin H for the reception of the
weight I which is centrally perforated.
The weight of the stirrup G is such that when in place it will just balance the
weighing platform or cover F, whether said cover be in one with the framework
which rests on the edges ff, f'f' as in Figs. 3 and 4, or whether it consists of a
scale plate resting on, but separate from, the framework which rests on the said
edges within the box D.
The scale represented in Figs. 3 and 4 is one especially designed for use in
bakeries, and the weights more usually required will therefore be those of 2 lbs.
and 4 lbs. respectively; and a 2 lb. weight is indicated in these figures of the
Drawings, in position upon the stirrup G.
To enable the baker readily to ascertain when the scale is in balance I provide
as an indicator, an extension A³ of the upper frame A, which plays through a slot
in the side of the box or case and by its position indicates whether the full weight
is on the scale plate or cover.
To prevent as far as possible dirt from entering the case and rendering inaccurate
the balance, I preferably form the cover with deep flanges all round, and to prevent
any tampering with the weight which has been placed in position within the case D
I provide the cover on its underside with slotted lugs f* and pass a locking pin or
bolt K through the slotted lugs and through holes in opposite sides of the case,
as clearly shown in Figs. 3 and 4. The slots in the lugs are of a length to permit
the free movement up and down of the scale plate or cover, and slots are provided
in the flanged edge of the said plate or cover at those points where the extension A²
and locking pin protrude.
I secure the locking pin in place by a padlock k. For some trades requiring the
weights to be frequently changed it is undesirable to have the cover non-detachable,
and in that case I may use a separate scale pan or plate which merely rests on the
framework supported on knife edges ffff within the case; see Fig. 2. The
internal weighing mechanism however remains as before, as does also the
indicator A2. The position and form of the indicator may vary, and the vertical
flange of the separate scale pan or plate may be dispensed with.
A self contained weighing machine of this kind, and more especially of the
pattern represented in Figs. 3 and 4, when made on a larger scale, is very useful
for rapidly weighing out sacks of coal in coal stores, and for similar purposes.
Referring now to Figs. 5 to 8 inclusive it will be seen that the internal weighing
mechanism, that is to say the compound lever movement, is the same as that above
described with reference to Figs. 1, 2 and 3.
The weighing platform or cover is also substantially the same as that shown in
Figs. 3 and 4 and is similarly mounted, but the meaps for preventing its detach-

page_text: ment are not required, for the weights in this machine are not suspended on a
hanging frame or stirrup within the box or case, but a steelyard and sliding
weights are adapted to the outside of the box or case below the level of the cover
and are connected with the compound lever movement within the case through an
extension of the upper lever frame A similar to that used as an indicator in the
foregoing examples, which extension may therefore be lettered A².
The end of this extension piece A² is forked to carry a knife edge on which
bangs a shackle or link m united by a loop or eye with a second shackle or link n
which supports a knife-edge o fast in the steelyard L. This steelyard is fulcrummed
at o¹ on a knife edge held down by a shackle or link p which is loosely mounted
on a pivot pin q projecting from the case D, all of which parts are clearly
represented in Figs. 5 to 8 inclusive.
The steelyard is fitted with sliding weights M N, the larger weight M fitting
loosely on the steelyard and having a knob or handle for shifting it to its proper
position and a fixed pawl or tooth adapted to be dropped into one of a series of
notches in the steelyard, for holding the weight in place; and the smaller weight N
sliding on the front of the steelyard and indicating the fractions of a lb, or other
known standard of weight.
I would remark that the steelyard might be enclosed by a covering or protecting
case of glass, wood or metal, adapted to be fixed and locked to the outside of the
main box or case and in this case the weighing platform or cover of the machine
would also be rendered non-detachable by a locking pin and lugs as shown in
Figs. 3 and 4.
A clamping screw or equivalent device would also be fitted to the sliding
weights M and N so that they could be locked or clamped upon the steelyard so as
to balance and indicate a certain definito weight of goods such as 2 lbs. or 4 lbs.
placed on the scale pan, platform or cover, but it has not been thought necessary
to show such arrangements in Figs. 5, 6, 7 and 8, of the Drawings.
The steelyard with non-detachable pivotted weight capable of being rapidly set
in one or other of two positions, as described in the specification of my invention
for which I obtained Letters Patent dated 26th February 1885 N° 2634, might
also be employed in lieu of the steelyard and weights represented in Figs. 5 and 6;
in combination with a compound lever similar to that hereinabove described and
shown in the Drawings, but it has not been deemed necessary to illustrate this
combination.
I would observe that in the present application for Letters Patent I make no
claim to any novelty in the steelyard per se, nor to novelty in the location of a
steelyard outside the case containing the compound lever movement, but :—
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
1. The construction and arrangement of the several table or counter weighing
machines hereinabove described with reference to the accompanying Drawings,
whereby I secure simplicity, strength and economy of space.
2. The combination with a shallow box or case as D, and a movable weighing
platform, scale plate or cover such as F, of a compound lever constructed arranged
and operating as described with reference to the Drawings for supporting and
maintaining the horizontality of the cover, during the weighing operation.
3. The combination with the box or case D and weighing platform or cover F,
of the compound lever arranged within the case and comprising the upper and
lower frames A A¹, cross bar B, side links or cheeks B' B' and appropriate bearings
and knife edges; one of the members of the said compound lever being prolonged
to play through a slot in the case below the said cover and serving as an index
when the weights are carried within the case, or as a means for transmitting
motion to a steelyard arranged outside the case, substantially us set forth.

page_text: 4. The combination with a shallow box or case as D, movable weighing platform
or cover F and a compound lever arranged within the box or case to carry the
said cover and maintain its horizontality in action, of a hanging frame or stirrup
such as G carried by the compound lever and adapted to receive a weight or
weights, as and for the purpose described with reference to Fige. 1 to 4 inclusive.
5. The construction and arrangement of weighing machine or table scale described
with reference to Figs. 3 and 4 of the Drawings in which machine the weights
are slung or carried entirely within the case, and means are provided for preventing,
when necessary, access to the interior of the case by the removal of the weighing
platform or cover, substantially as and for the purpose set forth.
6. The combination with a box or case D and a steelyard mounted as described
alongside the said case, of a movable weighing platform constituting a cover for
the case, a compound lever frame constructed, arranged and operating as described,
within the said case, and connections for transmitting the movements of the
compound lever to the said steelyard, all substantially as and for the purpose
described with reference to Figs. 5 to 8 inclusive of the Drawings.
