We, HENRY POOLEY and HENRY POOLEY Junior, both of Manchester Street,
Liverpool, in the County of Lancaster, Weighing Machine Manufacturers do hereby
declare the nature of our said invention to be as follows:-
This Invention relates more particulary to that class of weighing machines, which
"has to be deducted, or
are used for weighing goods, or articles from which "tare
allowances made. For instance it is applicable for weighing passengers luggage, or
other goods where allowances of stipulated quantities are made and are not charged
for, but for luggage or goods above those allowances charges are made for the extra
weight. Beyond these allowances-which form a kind of tare, another tare has in
most cases to be taken, and that is the tare for the barrow, or other vehicle, on, or by
which the luggage is placed and weighed.
I describe below a machine of the above cited kind with my improvements applied
thereto. It is however to be understood that some of the parts thereof may be
applied to other kinds of weighing machines. The main parts of such a machine
are: A platform or its equivalent for receiving the luggage; a steelyard connected
with the platform in the ordinary way, a dial and pointer and a weight which varies
automatically with different loads.
"
tare
"
The steelyard is preferably of triple form so arranged that three sets of weights are
controlled, or worked on it. One of these is the main loading weight, one a
for a barrow, or other vehicle and the third is a differential allowance weight. The
barrow or other carriage "tare" weight slides, or moves on, or in connection with a
har graduated in any known suitable way, whilst the differential allowance weight
slides, or moves on, or in connection with a bar graduated in such a manner that the
weight may be removed to and set at certain points corresponding with the allow-
ances of weight stipulated for passengers luggage for first, second, or third class or
any of them, and also with the allowances of weight stipulated for passengers
luggage having different allowances, such as for commercial travellers; these being
also divided into first, second, or third or any of them.

page_text: Therefore in weighing, the tare of the barrow, or other carriage, and the allowance
for either the ordinary, or other passenger being set upon their respective scales and
at their proper points, the pointer will not move unless the weight exceeds the allow-
ance, but if it exceeds the allowance the pointer will be moved and indicate the
extra weight of the luggage, and if the dial be a mileage rate one, and marked
with the charges for extra, or excess luggage the pointer will indicate at once the total
charge for the excess of luggage.
"
The dial may be of circular forin on a suitable frame and the pointer is worked by
the movement of the steelyard by a chain, or cord, or its equivalent.
The main weight consists of a body working in water and so arranged that as more,
or less weight comes upon the machine, the body will be more, or less raised out of,
or immersed in the water. This body is preferably of annular formation and open at
the bottom, having at the top an adjustable air valve, or aperture by which air is
drawn in and pressed out of the space between the roof of the body and the surface of
the water, as it is moved up and down. This arrangement causes the weighing to
be effected very steadily and quickly and the pointer to come to rest without any
material vibration. Suitable stops are provided in connection with the machine so
that the movements of the steelyard may be kept within proper limits and be locked
when the machine is not being used.
The whole appparatus is covered in by a suitable case and provided with a door at
that portion where the steelyard and weighing bars above described are located. The
machine is thus protected from attempt to tamper with it.

page_text: Improvements in or Connected with Weighing Machines.
We HENRY POOLEY and HENRY POOLEY Junior, both of Manchester Street, Liver-
pool, in the County of Lancaster, Weighing Machine Manufacturers, do hereby
declare the nature of our said invention 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 more particularly to that class of weighing machines which
are used for weighing goods or articles from which "tare" has to be deducted, or
allowances mado. For instance it is applicable for weighing passengers luggage,
where allowances of stipulated quantities are made and are not charged for, but for
luggage above those allowances charges are made for the extra weight. Beyond
these allowances which form a kind of tare, another tare in most cases has to be taken,
and that is the tare for the barrow or other vehicle on or by which the luggage is
placed and weighed.
We describe below a machine of the above cited kind with our improvements
applied thereto. It is however to be understood that some of the parts thereof may
be applied to other kinds of weighing machines. The main parts of such a machine
are A platform or its equivalent, for receiving the luggage; a steelyard in connec-
tion with the platform in the ordinary way; a dial and pointer, and a weight which
varies automatically with different loads.

The steelyard is preferably of triplo form, so arranged that three sets of weights are
controlled, or worked on it. One of these is the main loading weight, one a
for a barrow, or other vehicle and the third is a differential allowance weight. The
barrow or other carriage "tare" weight slides or moves on or in connection with a
bar graduated in any known suitable way, whilst the differential allowance weight
slides or moves on or in connection with a bar graduated in such a manner that the
weight may be removed to and set at certain points corresponding with the allow-
ances of weight stipulated for passengers luggage, for first, second, or third class,
or any of them and also of the allowance of weight stipulated for passengers luggage
having different allowances, such as commercial travellers, these being also divided
into first, second or third or any of them.
وو
Therefore in weighing the tare of the barrow, or other carriage and the allowance
for either the ordinary or other passenger being set upon their respective scales and
their proper points, the pointer will not move unless the weight exceeds the allowance,
but if it exceeds the allowance the pointer will be moved and indicate the "extra
weight of the luggage, and if the dial be a mileage rate one and marked with the
charges for extra, or excess luggage, the pointer will indicate at once the total charge
for the excess of luggage.
The dial may be of circular form on a suitable frame and the pointer is worked
by the movement of the steelyard by a chain or cord or its equivalent.
The main weight consists of a body working in water, and so arranged that as

•
The example of a machine according to our invention shown in the drawings, is of
that class which is used for weighing passengers luggage and where allowances of
stipulated quantities are made. A is the platform for receiving the articles to be
weighed B is the steelyard connected with the platform A in the ordinary way;
C is the dial; d is a pointer which is worked by a weight e and cord or chain
passing over a drum on the spindle ¹, the other end of the cord or chain being
connected to the steelyard.
The steelyard B is preferably of triple form, namely it is provided with three
bars a, a¹, a². One of these bars a carries the main loading weight 6; one, the bar a',
carries a
"tare" weight for a barrow or other vehicle; and the third, the bar a²,
carries a differential allowance weight 62. The bar a' on which the tare weight slides
or moves on is graduated in any known suitable way, and the bar a² is graduated in
such a way that the weight & may be removed to and set at certain points on the
bar a² corresponding with the allowances of weight stipulated for passengers luggage
for first, second, or third class or any of them, and also of the allowances of weight
stipulated for passengers luggage having different allowances, such as commercial
travellers, these being also divided into first second or third class, or any of them.
The main weight is carried by the bar a, it consists of a body b working in water
in a vessel H and so arranged that as more or less weight comes upon the machine
the body b will be more or less raised out of or immersed in the water. This body b
is preferably of annular formation and open at the bottom having at the top an
adjustable air valve or aperture i through which air is drawn in and pressed out of the
space between the roof of the body b and the surface of the water as it is used, up and
down.
This arrangement causes the weighing to be effected very steadily and quickly and
the pointer d to come to rest without any material vibration.
A device g is provided to lock the machine when not in use.
The dial is preferably in the form of the rate ring, a portion of which is shown at
Figure 4. This rate ring is marked with a scale representing the differential rates to
be charged for excess of passengers luggage for different distances or mileage namely
the excess charge up to 50 miles, 51 to 100 miles, 151 to 300 miles, over 300 miles.
The normal position of the steelyard is shown in Figure 1 in dotted lines. In

page_text: weighing, the tare of the barrow or other vehicle is taken by setting the tare
weight on its scale bar a¹ so as to balance the barrow, and the allowance weight b
is set on its scale bar a for the allowance for first, second, third class or other
passenger, when say the barrow of luggage is placed upon the platform A the
pointer d will not move on the dial C unless the weight of the luggage exceeds the
allowance, but if such weight exceeds the allowance the pointer d will move, and
indicate on the dial C the extra weight of luggage, and through the dial C being a
mileage rate scale and marked with the charges for excess of luggage, the pointer d
will indicate at once the amount to be charged for such excess.
The apparatus is covered in by a case F, the dial portion being glazed, provided
with a door G in front of the steelyard and weighing bars a, a, a, and when in use
this door G is open so that the weights 6 and 63 can be set to their required positions.
