IMPROVEMENTS IN WEIGHING MACHINES
Year: 1884

page_text: I PERCIVAL EVERITT of N° 13 Huggin Lane, Queen Victoria Street in the City
of London, Engineer, do hereby declare the nature of my said invention for
"IMPROVEMENTS IN WEIGHING MACHINES" to be as follows:-
My invention consists in so constructing a weighing machine that the act of
placing a coin or the like in the apparatus will cause the weight of the body being
weighed to be indicated on a dial or the like or on the pulling out of a slide or
drawer will deliver a ticket with the said weight printed or impressed thereon.
In order to carry out my invention I construct my machine with a platform or
other suitable device for receiving the body to be weighed the platform communi-
cating by any known arrangements of lever or levers with a counterpoise consisting
of weights or springs or weight and spring combined I preferably use a weighted
arm projecting from a pivoted spindle the arm being normally in a vertical position ;
the pivoted spindle communicating by means of suitable mechanism with the
platform is caused to rotate on its axis, when a body to be weighed is placed on
the platform and the said movement of the spindle will raise the weighted arm
until it counterbalances the body to be weighed.
The weighted arm or equivalent counterpoise is provided with gearing or other
suitable mechanism to operate an index inside the apparatus or an adjustable
arrangement of printing type inside the apparatus or both may be arranged to be
so operated. The index may be made to move in a circular or other direction and
the arrangement of printing type may consist of discs having the type on their
peripheries or any other arrangement of adjustable type may be used.
Outside the apparatus I use an index moving in a circular or other suitable
direction which being attached to gearing or other suitable mechanism inside the
apparatus is caused to move by the weight of a coin placed in a receptacle attached
thereto. The movement of the outer index is regulated by a stop which comes in
contact with the index inside the apparatus. On the counterpoise reassuming its
normal position which is effected by the removal of the body being weighed the
indexes are moved back by the gearing or equivalent mechanism to their starting
point and the receptacle for the coin is thereby brought into contact with a tumbler
bolt or catch or other suitable device which opens the receptacle and delivers the
coin into a box for receiving the same.
Inside the apparatus I place a number of cards adjacent to the printing type;
the card nearest to the type may be delivered to the outside of the machine by

page_text: means of a slide or drawer actuated by hand from the outside, the said slide or
drawer having a projection or other device for withdrawing the card, the slide or
drawer when pushed into the apparatus is automatically held fast by a tumbler
bolt or catch or other suitable device the said bolt or catch communicating by
means of levers or other suitable mechanism with a receptacle for a coin which
coin on being placed therein will counterbalance or otherwise release the bolt or
catch and the slide or drawer can then be pulled out. The slide or drawer com-
municates by means of levers or other suitable mechanism with the printing device
by which means on the outward motion of the slide or drawer before the projection
on the same pushes out the card the type is caused to come into contact with the
nearest card and imprint or impress the said card with the weight of the body
being weighed the adjustment of the type for this purpose having been effected by
the movement of the weighted arm or equivalent counterpoise. As the slide or
drawer is continued to be pulled out the type recedes from the card and the pro-
jection on the slide or drawer comes in contact there with and the printed card is
thereby delivered outside the apparatus.
If desired in order to lessen the shock which would be caused by the counter-
poise suddenly reassuming the normal position on the removal from the platform
of the body being weighed I employ a mechanism for retarding the same which
mechanism may consist of a fly escapement or an air cushion consisting of an
arrangement of piston fitting loosely in a cylinder so as to allow of the gradual
passage of the air or any other equivalent device may be used for this purpose.

page_text: I PERCIVAL EVERITT of N° 13 Hoggin Lane, Queen Victoria Street, in the city
of London, Engineer do hereby declare the nature of my said invention for
"IMPROVEMENTS IN WEIGHING MACHINES" and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement:-
My invention consists in constructing a new kind of weighing machine in such
manner that the act of placing a coin or the like in the apparatus will cause the
weight of the body being weighed to be indicated on a dial or the like, or the
pulling out of a slide or drawer will deliver a Ticket with the said weight printed
or impressed thereon.
In order to carry out my invention I construct my machine with a platform or
other suitable device for receiving the body to be weighed, the platform communi-
cating by any known arrangements of lever or levers with a counterpoise consisting
of weights or springs or weight and spring combined. I preferably use a weighted
counter balanced arm projecting from a pivoted spindle; the pivoted spindle, com-
municating by means of suitable mechanism with the platform, is caused to rotate
on its axis when a body to be weighed is placed on the platform, and the said
movement of the spindle will partly rotate the weighted arm until it counter-
balances the body to be weighed.
The weighted arm or equivalent counterpoise is provided with gearing or other
suitable mechanism to operate an index inside the apparatus, or an adjustable
arrangement of printing type inside the apparatus, or both may be arranged to be
so operated. The index may be made to move in a circular or other direction and
the arrangement of printing type may consist of discs having the type on their
peripheries, or any other arrangement of adjustable type may be used.
Outside the apparatus I use an index moving in a circular or other suitable
direction which being attached to gearing or other suitable mechanism inside the
apparatus is caused to move by the weight of a coin placed in a receptacle attached
thereto. The movement of the outer index is regulated by a stop which comes in
contact with the index inside the apparatus. On the counterpoise reassuming its
normal position, which is effected by the removal of the body being weighed, the
indexes are moved back by the gearing or equivalent mechanism to their starting
point; and the receptacle for the coin is thereby brought into contact with a pin
or catch or other suitable device which opens the receptacle and delivers the coin
into a bag or box for receiving the same.
Inside the apparatus I place a number of cards adjacent to the printing type;
the card nearest to the type may be delivered to the outside of the machine by
means of a slide or drawer actuated by hand from the outside, the said slide cr
drawer having a projection or other device for withdrawing the card. The slide
or drawer communicates by means of suitable mechanism with the printing device,
by which means, on the outward motion of the slide or drawer before the projec-
tion on the same pushes out the card, the type is caused to come into contact with
the nearest card and imprint or impr. ss the said card with the weight of the body
being weighed, the adjustment of the type for this purpose having been effected

page_text: by the movement of the weighted arm or equivalent counterpoise. As the slide
or drawer is continued to be pulled out, the card recedes from the type, and the
projection on the slide or drawer comes in contact with the printed card which is
thereby delivered outside the apparatus.
If desired, in order to lessen the shock which would be caused by the counter-
poise suddenly reassuming the normal position on the removal from the platform
of the body being weighed, I employ a mechanism for retarding the same, which
mechanism may consist of a fly escapement or an air or other cushion consisting of
an arrangement of piston fitting loosely in a cylinder so as to allow of the gradual
passage of air, or other fluid; or any other equivalent device may be used for this
purpose.
In order to enable my invention to be fully understood, I will proceed to describe
the same by reference to the accompanying drawings in which figure 1 is a sido
elevation partly in section of a weighing machine constructed according to my
invention and in which the weight of a body being weighed is indicated on a dial;
figure 2 is a front elevation with the lower part of the machine removed; figure 3
is a horizontal section on line A. B. of figure 1; figure 4 is a horizontal section on
line CD of figure 6; figure 5 is a vertical section on line E. F. of figure 4, the
lower part of the machine being removed; figure 6 is a vertical section on line G. H.
of figure 5; figure 7 is a vertical section of part of a weighing machine in which
the weight of a body being weighed is printed on a ticket which is delivered on
the opening of a drawer, the section being taken on the line I. J. of figure 8, which
is a vertical section on line KL of figure 7; figure 9 is a vertical section on
line M. N. of figure 7; and figure 10 is a plan of figure 9. Figures 1. 2 and 3 are
drawn to a scale of about one sixth full size and figures 6 to 10 about one third
full size.
Similar letters in all the figures represent similar parts.
I will first describe my Invention by reference to figures 1 to 6; a. is the plat-
form of the machine which is supported upon knife edges b, carried upon frames c
and d, which are suspended by means of hooks e, from knife edges f, fixed to the
frame g. of the machine; the frame d is similarly suspended by a hook h. from the
frame c; the said method of supporting the platform c is that usually employed in
Platform weighing machines; i is a lever or arm consisting of an extension of tho
frame c. and serving by means of the hooked lever or rod j, and steel riband k. to
connect the platform a. with the counterpoise hereinafter described; the arm i is
provided with a knife edge m, bearing in the lower or hooked end of the rod j; l. is
the weighted arm projecting from the pivotted spindle n. which arm l. together with
a weight o. forms the counterpoise of the platform a.-A cord p, by which the
weight o. is suspended passes round a pulley q. fixed on the spindle n; the
steel riband k. is attached to and wound upon the spindle n. so that when a
weight is placed upon the platform a. the said riband will partly rotate the
spindle n. and pulley q., and the weight o. will be raised, and the weighted arm 1,
will partly rotate in the direction shewn by the arrow until the weights 7. and v.
counterbalance the body to be weighed; r. is a toothed quadrant fixed on the
spindle n. and serving to operate when the spindle is rotated, a pinion 8. fixed upon
an arbor t which carries at one end the index u;-v (figure 2) is the index moving
over a dial w. placed outside the apparatus which index serves to indicate the
weight of the person or body being weighed; on the arbor a (figures 4 and 6) of
the index v is fixed inside the apparatus a pinion y which gears with a quadrant z
pivotting at a¹ and provided with a counterweight b6¹; to the quadrantz is attached
an arm c¹ which carries the receptacle or box d¹ for the Coin h¹ and having an open
top; the box d¹ is normally situated immediately below a shoot e³, extending from
a slit f in the frame or case g of the apparatus, as shewn in figures 5 and 6;-the
box d¹³ is provided with a slit g¹ of a less height than the diameter of the Coin h¹
which is necessary to operate the mechanism; the shoot e', is formed with an
opening e, in its bottom of such a size that any coin smaller than the size of the
predetermined coin will pass through the said opening into the apparatus without

page_text: operating the parts; is the bottom of the box d which bottom is moveable
upon a pivot and which is kept in its closed position by a counterweight k¹
except when the arm is operated by the weight of a Coin placed therein as herein-
after described; is the stop for regulating the movement of the outer index v by
coming in contact with the index u, inside the apparatus; the stop is fixed on
the inner end of the arbor of the index v and when the pinion y is rotated by a
Coin dropped into the box d' over balancing the arm c¹ and operating the quad-
rant z the stop will rotate until its projection meets the index u when it will be
stopped thereby at the proper position to indicate by means of the outer index v
the weight of the body upon the platform a. When the weight is removed from
the platform a and the weighted arm and weight o reassume their normal
positions, the index u will in rotating, bear against the stop so as to again raise
the receptacle or box d¹; m¹ is a finger or catch pivotted at n' to the moveable
bottom of the box d¹ in such a manner that when the box is depressed by the
weight of the coin h¹ placed therein the finger or catch m³ will by coming in
contact with the pin or catch o¹ on the frame or case g. of the machine be caused
to turn on its pivot n' and pass by the pin o¹; when however the box d'is again
raised by the removal of the weight from the platform a the finger or catch will
again be brought into contact with the pin o¹ but will remain rigid so as to cause
the bottom of the box or receptacle to open and deliver the Coin into the bag pl
or other suitable receptacle; q¹ figure 1. is the cylinder in which fits loosely a
piston connected by a rod r¹ to the pulley 9; the said cylinder contains water or
other suitable fluid, which serves as a cushion in order to lessen the shock on the
weights and o reassuming their normal position when the weight is removed from
the platform a.
a is a fly on the arbor which also assists in retarding the movement of the
mechanism and weights of the machine.
By this construction of weighing machine if a person place himself (or a body
to be weighed be placed) on the platform a the spindle n. will by means of the
arm i. rod j and steel riband k be partly rotated and the weight o will be thereby
raised, and the arm 7 rotated a certain distance according to the weight of the person
being weighed; this movement of rotation will be communicated to the index u
by means of the quadrant r and pinion 8. the said extent of movement of the
index u being practically that to which the index v will be subsequently moved to
indicate the weight on the dial w;-if a coin of a predetermined size be now
passed through the slit fit will pass into the box or receptacle d' and by its
weight will overbalance the arm c¹; the arm c¹ in falling will by means of the
quadrant z and pinion y, rotate the stop together with the index v on the dial w
until the projection on the stop comes against the index u and the weight of the
person on the platform a will be thus indicated on the dial w. Upon the person
stepping off the platform a the weights will resume their normal positions and the
index u as it is carried back by the mechanism will carry with it the stop l¹ and
the box or receptacle will be thereby raised, the bottom of the box d¹ will be opened
by the finger or catch m¹ coming against the pin o¹ and the coin h¹ will be discharged
into the bag p¹ If a smaller coin than that predetermined should be dropped
through the slit f¹ it would simply pass through the opening e' in the shoot e' into
the bag p¹ without operating the mechanism, and the slit fi would of course be of
such a size as would not admit of the introduction of a larger coin than that
required.
In the arrangement shown in figures 7 to 10 the mechanism for weighing a body
placed on the platform of the machine is similar to that hereinbefore described and
shewn in figures 1 to 6 but instead of causing the quadrant r and pinion s to
operate an indicating device I cause them to operate an adjustable arrangement of
printing type for printing the weight on tickets.
t' is the disc which is fixed on the arbor t and having on its periphery a series of
type; the said disc with its type is so arranged that the type representing the
weight of the body on the platform shall be brought by the quadrant r and

page_text: pinion & under the lowermost of a pile of cards or tickets u¹ contained in a box o¹
having a vertical sliding motion in guides w¹; c¹ xl are wheels or rollers moving
over the guides w¹ for assisting the said sliding motion of the box v¹; the bottom
card or ticket rests on a flange or ledge y' on two sides of the box at the bottom
thereof; the rest of the bottom of the box is open; z¹ is the slide or drawer which
is formed with an opening a therein; b' is the projection on the slide or drawer z¹
which projection when the slide or drawer is drawn out by means of its handle c³
passes between the flanges or ledges y' and comes in contact with the lowermost
card and forces it forward so as to deliver it outside the apparatus; d³ dare
rollers on the card or ticket box v¹ which rollers work on the sides of the slide or
drawer and support the card or ticket box; e³ ³ are depressions in the sides of the
slide or drawer in which depressions the rollers d' enter as the slide or drawer is
pulled out, whereby the box v¹ is lowered on to the type disc t¹ so as to print the
lowermost card or ticket; in order to prevent the card or ticket box v³ from
being again lowered when the slide or drawer Z' is pushed back into the apparatus.
I provide a tumbling lever f³ pivotted to the support or slide g* of the drawer and
working between two stops h³ h²; i is a pin or projection on the box v' under
which pin the tumbling lever f³ is moved to support the box while the drawer is
pushed inwards; is a spring catch or finger which when the slide or drawer Z¹
has been almost completely opened comes against the lever f*; and pushes it
under the pin or projection and against the front projection h; as the slide or
drawer is continued to be pulled out the spring catch will turn on its pivot k
and be forced past the lever f'; as the slide or drawer Z¹ is pushed back within
the apparatus the spring catch will easily turn on its pivot and pass the lever ƒ2
without removing it from its position under the pin or projection is; as the slide
or drawer Z¹ is completely closed a projection thereon comes against the front
edge of the lever f and forces it from under the pin or projection is into the
position shewn in figure 9; m³, is a weight placed on the top of the pile of cards
or tickets in order to ensure them being presented at the bottom of the box v', in
proper position to be printed on and delivered; n' is an endless band of carbon
paper or the like which passes round four pulleys 02, 02 and over the periphery of
the type disc t' immediately under the pile of cards or tickets u' so as to print
the bottom card when the box v¹, is lowered; in order to communicate motion
to the band of carbon paper n³ so as to continually present a fresh portion in
position to be pressed upon by the type, I provide one of the pulleys 03 with a
ratchet and click arrangement p² operated by means of a roller q%, on the end of
a rod and working in a cam-shaped groove S2 shewn in dotted lines at figure 10
in such a manner as to move the ratchet wheel with its pulley O', forward one tooth
each time the drawer is closed.
By this arrangement when a body to be weighed is placed upon the platform of
the machine the type disc t' will rotate until the type representing the weight
of the said body comes immediately under the card or ticket box v¹; if the slide
or drawer Z¹, be then drawn out the rollers d' entering the depressions e³ will cause
the card or ticket box to be lowered and the lowermost card or ticket will be
pressed upon the carbon paper n³ and type disc t'; as the slide or drawer is con-
tinued to be drawn out the card box v¹, is raised from the type disc t¹ and the
projection 6, on the slide or drawer comes against the edge of the printed card
and delivers it outside the apparatus.
The mechanism for delivering and printing tickets with the weight thereon as
herein before described and shewn in figures 7 to 10 can be arranged so that the
slide or drawer when pushed into the apparatus shall be automatically held fast by
a tumbler-bolt or catch or other suitable device the said bolt or catch communicating
by means of levers or other suitable mechanism with a receptacle for a coin; which
coin being placed therein will counterbalance or otherwise release the bolt or catch;
and the slide or drawer can then be pulled out.
Although I have described and shown the arrangements for indicating weight
and for delivering tickets with the said weight printed thereon as applied to

page_text: separate machines, it will be obvious that, as the weighing mechanism is similar
in each case, both the said arrangements can if required be combined in one
apparatus.
Although I have described and shewn only one pin or catch 01, it may be
sometimes necessary to employ more than one of such pins or catches; and instead
of employing an arrangement of weights for weighing the body as herein before
described and shewn I can make use of a spring for this purpose which would be
connected by suitable mechanism with the indicating device or with the printing
mechanism.
Having now particularly described and ascertained the nature of my invention
and in what manner the same is to be performed I declare that what I claim is
1. The manufacture and use of a new kind of weighing machine such as is
herein described in which, on a coin or the like being placed in the apparatus, the
weight of a person or body being weighed will be indicated on a dial or the like
substantially as hereinbefore described.
2. The manufacture and use of a weighing machine such as is herein described,
in which the operation of pulling out a slide or drawer will print or impress the
weight of a person or body being weighed, upon a card or ticket and will deliver
the same outside the apparatus substantially as hereinbefore described.
3. The combination with weighing mechanism of suitable construction such as is
herein described, of an arrangement whereby a coin is caused to operate an index
or indicator as and for the purpose hereinbefore described and represented in
figures 1 to 6 of the accompanying drawings.
4. The combination with weighing mechanism of suitable construction such as is
herein described of an arrangement whereby the weight of the person or body being
weighed is caused to be printed or impressed upon a card or ticket as hereinbefore
described and represented in figures 7 to 10 of the accompanying drawings.
5. The improved weighing machines hereinbefore described and represented
respectively in figures 1 to 6 and 7 to 10 of the accompanying drawings.
