We, HENRY POOLEY of Albion Foundry Liverpool in the County of Lancaster,
Engineer and JOHN CHATER of Peckham Rye in the County of Surrey Engineer
do hereby declare the nature of this invention to be as follows:-
According to our invention we construct steel yards with improved arrangements
and combinations of printing appliances or gear whereby we are enabled to print the
weights of articles weighed, in an accurate, clear and legible manner, and in current
weight denominations, and so that the whole apparatus shall effect the object of
printing in a simple and efficient manner without being unduly liable to wear.
We provide the steel yard, by preference on the bottom, or on one side, with a
toothed rack, and actuate the printing apparatus therefrom by means of a pinion
gearing with the rack and attached to the sliding weight.
From this pinion we drive type wheels by means of tooth wheels having the
proper mutually proportionate number of teeth in accordance with the current weight
denomination and we also prefer to provide locking appliances for holding the type
wheels in position while printing.
The type wheels are all on one spindle and arranged so as to turn independently of
each other. The driving pinion may be on the samo spindle as the type wheels or ou
a separate spindle.
One mode of constructing our improved weight printing steel yard is as follows:-
On the spindle of the driving pinion are fixed two tooth wheels, one an ordinary
one which we will call the first driver tooth wheel, and the other a tooth wheel having
only very few broad equidistant teeth with wide intermediate spaces and which wheel
we will call the first driver dog-tooth wheel.
The first driver tooth wheel gears with a tooth wheel which is fixed on or formed in
one with a wheel having on its circumference raised types corresponding to division
notches on the steel yard, and, for instance, answering to quarters of a hundred weight;
When this
a catch on the sliding weight takes in these notches in the usual manner.
first type wheel has travelled a distance corresponding to four quarters, a tooth on the

page_text: aforesaid dog-tooth wheel becomes engaged with a wheel capable of turning freely on
the same spindle as the first type wheel and fixed or formed in one with a second type
wheel which is provided with raised types corresponding to hundred weights.
On the first driver spindle is also fixed a wheel or disc having notches corresponding
in number with the teeth on the dog tooth wheel and on the type wheel spindle and
fixed to or in one with the aforesaid second type wheel we provide a wheel or disc
which we call the "wave wheel" and whose periphery is divided into a series of
concave segment like surfaces into any of which the aforesaid notched disc can fit.
The notches in the aforesaid disc allow the wave wheel to turn when one of the
dog teeth is driving the type wheel from one type to another, but the circum-
ference of the said disc falls into one of the concave surfaces of the wave
wheel, the instant the change of types is effected and thus locks the " wavo
wheel and its attached type wheel securely in position, whilst the printing is
being done. We sometimes form one or more of the type wheels with cup shaped
recesses corresponding in number to the number of type figures and provide a spring
catch which drops into a cup recess whereby the type wheel is held in place whilst the
printing is being done.
دو
When the sliding weight as we prefer it is fitted with a small vernier or supple-
mentary sliding weight by the use of which more minute weighings are ascertained
we provide the latter with a rack which gears with a pinion fixed on the type wheel
spindle and fixed to or in one with a third type wheel the types of which correspond
to pounds. The spindle of this pinion is furnished with a small milled knob or wheel
by turning which we are enabled to propel the small sliding weight or vernier on the
large sliding weight.
The tickets to be printed on are inserted in a slot opposite the type wheels and
pressed against the same by a cam lever. In order to make the impression clear we
provide the tickets with a carbonized paper slip which imparts colour to the impression
of the type and which is torn off when done with.

page_text: Improvements in Weight Printing Steel-yards.
We, HENRY POOLEY of Albion Foundry Liverpool in the County of Lancaster
Engineer and JOHN CHATER of Peckham Rye in the County of Surrey Engineer 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:
According to our invention we construct steel yards with improved arrangements
and combinations of printing appliances or gear whereby we are enabled to print the
weights of articles weighed in an accurate clear and legible manner and in current
weight denominations and so that the whole apparatus shall effect the object of printing
in a simple and efficient manner without being unduly liable to wear.
We provide the steel yard by preference on the bottom (or on one side) with a
toothed rack and actuate the printing apparatus therefrom by means of a pinion
gearing with the rack and attached to the sliding weight. From this pinion we
drive type wheels by means of tooth wheels having the proper mutually proportionate
number of teeth in accordance with the current weight denomination and we also
prefer to provide locking appliances for holding the type wheels in position while
printing.
The type wheels are all on one spindle and arranged so as to turn independently of
each other. The driving pinion is on a separate spindle (or may as will be described
further on be on the same spindle as the type wheels).
One mode of constructing our improved weight printing steelyard will be described
with reference to Figures 1 to 5 and another to Figures 6 to 9: As regards
Figures 1 to 5 it is as follows. The stoel yard A shown in dotted lines in the plan
section Fig. 1. has teeth on the bottom into which gears the pinion B on the sliding
weight. On the spindle of the driving pinion B are fixed two tooth wheels, one an
ordinary one which we will call the first driver tooth wheel E and the other a tooth
wheel Chaving only very few broad equidistant teeth with wide intermediate spaces
as shown separately in Figure 2 and which wheel we will call the first driver dog
tooth wheel.
The first driver tooth wheel E gears with a tooth wheel E¹ which is fixed on or
formed in one with a wheel F bearing on its circumference raised types corresponding
to division notches on the steelyard and for instance answering to quarters of a
hundredweight; a catch on the sliding weight takes in these notches in the usual
manner. When this first type wheel F has travelled a distance corresponding to four
quarters a tooth on the aforesaid dog tooth wheel C becomes engaged with a wheel G
shown separately in Figure 3 and capable of turning freely on the same spindle as
the first type wheel F and fixed or formed in one with a second type wheel H.which
is provided with raised types corresponding to hundredweights.

page_text: On the first driver spindle is also fixed a wheel or disc I shown separately in
Figure 2 having notches corresponding in number with the teeth on the dog tooth
wheel C, and on the type wheel spindle and fixed to or in one with the aforesaid
second type wheel we provide a wheel or disc K shown separately in fig. 3 and
which we call the wave wheel and whose periphery is divided into a series of concave
seginent-like surfaces into any of which the aforesaid notched disc I can fit. The
notches in the aforesaid disc I allow the wave wheel K to turn when one of the dog
teeth is driving the type wheel H from one type to another but the circumference of
the said disc I falls into one of the concave surfaces of the wave wheel K the instant
the change of type is effected and thus locks-the-wave wheel K and its attached type
wheel H securely in position whilst the printing is being done.
We sometimes form one or more of the type wheels with cup shaped recesses
corresponding in number to the number of type figures and provido a spring catch
which drops into a cup recess whereby the type is held in place whilst the printing
is being done. Such spring catches Mand Mare shown applied to the wave wheel K
and the type wheel D.
When the sliding weight as we prefer it is fitted with a small vernier or supple-
mentary sliding weight by the use of which more minute weighings are ascertained
we provide the latter with a rack or make it in the form of a rack Vshown soparately
in Figure 4 which gears with a pinion V₁ fixed on the type wheel spindle Oand
fixed to or in one with a third type wheel D the types of which correspond to
pounds...
The spindle of this pinion V₁ is furnished with a small milled knob or wheel 01 by
turning which we are. enabled to propel the small sliding weight or vernier V. on
the large sliding weight. Figure 4 is a front view of this small sliding weight and
Figure 5 a plan of part of top of the large sliding weight showing the graduated
divisions corresponding to the position of the index picco V× on the small sliding
weight V.
.
We shall next describe an example of the second arrangement in which the
driving pinion B is on the same spindle as the type wheels. This is shown in Figure 6
which is a front view with the cover removed to show the wheel gearing inside the
sliding weight. Figure 7 is a plan of the gear in the sliding weight the body of the
latter being in section. Fig. 7 is a plan section through the gear and Figure 8
a front view of the sliding weight drawn to a smaller scale. Figures 9 and 10. are
detail views and Fig. 11 a view of a Ticket printed by the apparatus. In this case
also the steelyard A is shown with a toothrack along the bottom the tooth pinion B
gearing therewith. The pinion B is loose on the spindle O and has a long boss on
which runs freely the type wheel R which indicates the highest denomination of
weight such as tons. To the type wheel R are fixed the wave wheel Q and the dog
tooth wheel S. On the boss of the pinion B is fixed the first driver tooth wheel E
and also the type wheel H which has raised types indicating hundredweights. The
first driver tooth wheel E gears with the tooth wheel C which is fixed on the boss of
the notched disc P this latter being fixed on the spindle T. On the spindle O the type
wheel F for quarters of a hundredweight is loose and on its boss are fixed the dog
tooth wheel I and the wave wheel K, these two working or goaring with the notched
disc or wheel L with four toeth or pins L' on its side. Spring catches M M and M
are shown applied respectively to the type wheel R and to the dog tooth wheel I on
the type wheel F and to the spur wheel B¹ which is fixed to the type wheel D. The
spring catches M and Monter into cup recesses, while the spring catch M¹ enters
between two teeth of the dog tooth wheel I.
The tickets to be printed off are inserted in a slot opposite the type wheels and
pressed against the same by a cam lever N. In order to make the impressions clear
we provide the tickets with a carbonized paper slip which imparts colour to the
impression of the type wheels and which is torn off when done with. When the
ticket is to have the tare weight as well as the gross weight printed on it we provide
a small frame X for holding the ticket while being printed on and slide this frame by
the knob X¹ first to the left against a stop for the upper part of the ticket to have the

page_text: gross weight printed thereon. Afterwards when the tare weight is to be ascertained
the slide with the ticket in it is slided towards the right against a stop and the
tare weight can then be printed on it. The two weights will thus appear in a legible
manner one below the other. Figure 11 shows such a ticket.
Generally speaking by the arrangements described we ensure that the types which
are about to print will produce impressions on the ticket all in a straight line; this
is owing to the absolutely accurate and rigid manner in which the type wheels are
held in place by means of the wave wheels and the discs which fit into their concave
recesses, the spring catches assisting the wave wheels to hold the type wheels firmly
and also neutralizing the effect of any back lash in the wave wheel parts. One of
the spring catches in the case of the sinall sliding weight assists to set the corre-
sponding type wheel in the exact position so as to indicate even weight.
Having thus particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed we declare that what wo
claim is :-
First. In connection with type wheels in sliding weights or poisos for steelyards
the application of wave wheels dog tooth wheels and toothed notched discs for the
purpose of driving and controlling the type wheels substantially as described.
Second. In connection with type wheels in sliding weights for steel yards the
application of spring catches and corresponding cup recesses or other recesses for the
purpose of assisting in setting the type wheels to the exact position required for printing,
substantially as described.
Third. The improved mode and means of printing weight tickets substantially as
described and shown.
Fourth. The constructions of sliding weight for steelyards substantially as described
with reference to the accompanying drawings.
