I WILLIAM BEILBY AVERY OF 12 Digbeth Birmingham in the County of Warwick,
Machine Maker do hereby declare the nature of this invention to be as follows:-
The object of this invention is to adapt a ribbon or band of paper to the steelyard of
a weighing machine, whereby a record of the weighings may be retained in the
machine for subsequent use.
In carrying out this invention, I mount at the end of a steelyard a frame in which
are mounted a pair of rollers or drums for carrying the ribbon or tape. These drums
are mounted loosely on their axes, and that from which the paper is unrolled is provided
with springs which press against it, and whereby its motion is regulated. The other
drum is provided with a ratchet wheel into which takes a pawl suitably placed for the
purpose, and which, as the steelyard rises after the load is removed, serves to rotate
the drum, and drag on the paper, by which means a clean portion of the paper is
presented to the type at the next weighing. The band is passed round a pair of
guide rollers suitably placed for the purpose, and between which a plunger is arranged
to descend to press the band against the type, which are arranged below.

page_text: I WILLIAM BEILBY AVERY of Digbeth, Birmingham in the County of Warwick,
Machine Maker, do hereby declare the nature of this invention and in what manner
the same is to be performed, to be particularly described and ascertained in and by
the following statement :-
The object of this invention is to adapt a ribbon or band of paper to a steelyard
weighing machine so that a printed record of the weighings may be retained in the
machine for subsequent use.
In carrying out this invention I arrange at the top of the pillar of a steelyard
weighing machine a frame in which are mounted loosely a pair of rollers or drums for
carrying the ribbon or tape. The drum from which the paper is unrolled is provided
with a spring or springs which press against it and whereby its motion is regulated.
The other drum is provided with a ratchet wheel arrangement into which takes a
pawl suitably placed for the purpose and which serves to rotate the drum and drag on
the paper, by which means a clean portion of the paper is presented to the type at the
next weighing. The band is passed round a pair of guide rollers suitably placed for
the purpose and between which a plunger is arranged to descend to press the band
against the type which are arranged below.
In the accompanying drawings Fig. 1 Sheet 1 is a side elevation of so much of a
steelyard weighing machine as is necessary to show my invention Fig. 2 is a plan
view of the same and Fig. 3 is a cross section.
Fig. 4 Sheet II is a side elevation of the steelyard with the frame carrying the
paper removed and Fig. is a back view of the frame.
The steelyard is composed of two bars A A' which are connected together by bracket
pieces or stays and carry between them the scale plate A. The steelyard has its
fulcrum at a and also a knife edge b to receive the rod connecting it with the platform.
The bar A carries on its upper edge the large weight B, and the bar A¹ is slotted
atc (see Fig. 1) to receive a handle B¹ for the purpose to be hereafter explained.
To the weight B is attached a bar C which is formed with two rows of type thereon
representing the cwts and qrs marked on the scale plate A2. The handle B₁ is
connected to a second bar C₁ formed with a single row of type thereon representing
the lbs on the scale plate.
These type bars may be made in any manner most convenient to ensure accuracy
and the numbers will run in the opposite direction to those on the scale plate. The
type will be so arranged on the bar that in which ever notch on the steelyard the
weight may be set the type corresponding to the number of that notch will be brought
exactly over the centre line of the knife edge a. The rear end of the steelyard is
slightly prolonged to provide a rest for the type bars and these parts are enclosed in a
convenient box or casing fitted to the pillar of the machine and provided with a door.
Pivotted to the rear side of this case is a curved arm or lever D which spans the
weight B and is provided at its front end with a block or presser D'.-Pivotted also
to the back of this box is a cam lever E the cam of which overlies the block 1' so that
when the lever is pulled forward the cam will force the block down onto the type the
return movement of the block being caused by the spring D². This block is so
arranged that the pressure will be received by the centre a and thus a. firm pressing
surface will be obtained.

page_text: The printing mechanism is enclosed in the box and placed longitudinally across this
box is a vertical partition H, to which are secured in the same vertical line two
studs HH to carry the frame with the roll of paper.
This frame consists of a plate I which is cast or formed with two sleeves II on its
rear face which fit into the studs H H and by means of which the plate I is held and
its position is fixed. This plate carries stud axles on which the paper holders J.J'
and the guide rollers K are mounted. The paper band is unwound from J and is
wound up on passing on its way under the guide rollers K.-The guide rollers K.
are distanced sufficiently apart to permit of the block or presser D' descending under
the influence of the cam handle E as before explained.
The rotation of the wheel J' to present a fresh portion of the band to the type after
each printing, is effected by a pawl E¹ carried by the cam handle E which pawl on
the return movement of the handle E after it has been used to operate the block or
presser D¹ is caused to act on a ratchet wheel L and move it round one tooth or in
any other convenient manner. The ratchet wheel L is mounted on a stud axle secured
to the partition H and it is formed with a number of holes on its face into one of
which a pin or pins on the roller Jenters when the latter is placed in position and
by means of which the roller J' is rotated.
When a band of paper is used I prefer to employ a piece of black or other printing
paper by means of which the numbers will be printed on the paper when the pressure
is applied by the descent of the block D. The black paper may be applied either
above or below the band and when it is desired to print a ticket in addition to the
registering band the ticket may be introduced either above or below the band and
through a slot or opening which may be provided in the door for the purpose.
A finger d is provided to press upon the roll J partly to prevent its undue rotation.
This finger is carried by a pivot pin d' on the end of which is mounted a spring d.
This spring d extends into the path of a projection d³ on the door which as the door
is closed presses down the spring d³ rocks the pivot d¹ and causes the finger d to press
upon the paper with an elastic pressure. Attached to the pivot pin is a second
finger d' which as the pivot is rocked rises so that by the time the paper is entirely
unrolled from the roller J the finger will have risen into the path of a projection d
on the side of the lever E and thus prevent the lever being worked until such time as
a fresh roll of paper is placed in position and the finger returns to its normal
position.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed I would here remark that I make no
claim per se for the mode of arranging the type bars in combination with the weights
nor for the mode of giving the pressure to effect the printing both of which have been
in use for some years but what I do claim is :-
1. The combination of parts constituting a steelyard weighing machine adapted to
print the weight of the goods on a band of paper substantially as herein shown and
described.
2. In a steelyard weighing machine in which the weight of the goods is to be
printed on a band of paper the adaptation to the top of the pillar of the machine and
above the printing or impression type of means for carrying the band of paper and
intermittently advancing the same as set forth.
3. The combination of parts constituting the means for carrying the band of paper;
for intermittently advancing the said band and for locking the printing mechanism
when the band of paper has run out all substantially as herein shown and described.
