Mechanical Engineer, for an Invention of "IMPROVEMENTS IN AND CONNECTED
WITH STEEL YARDS FOR WEIGHING MACHINES."
PROVISIONAL SPECIFICATION left by the said John Chater at the Office
of the Commissioners of Patents on the 23rd January 1880.
JOHN CHATER of Peckham Rye in the County of Surrey Mechanical Engineer
" IMPROVEMENTS IN AND CONNECTED WITH STEEL YARDS FOR WEIGHING
MACHINES."
The object of this Invention is to provide a ready means for ascertaining the
weight and for reading off the same while at the same time if desired to afford
means for rendering the weights in two or more standard national measures, such
as French and English measure.
According to this Invention I form the steel yard with two or more arms or
parts with intervening or adjoining space or spaces; on the arins which need not
be graduated the sliding weights with pointers are placed and in the space or
spaces I fit one or more fixed or movable scale bars which may be of three or more
sides or cylindrical. By using a revolving scale bar pivoted at each end and
having two or more faces I obtain facility for indicating the weight in two or
more standard measures say French and English. When using a hexagon revolving
scale bar I may thus for instance on one of the six faces mark the words
English measure;" on the two adjoining faces I have on one a scale for the tons
and on the other a scale for the hundred weights and quarters; the other three
faces of the scale bar may then be marked and divided correspondingly for French
**
or other measure.
Stops or catches or other suitable means may be fitted to the end or ends of the
scale bar for retaining it in any of the desired positions.

"IMPROVEMENTS IN AND CONNECTED WITH STEEL YARDS FOR WEIGHING
MACHINES."
The object of this Invention is to provide a ready means for ascertaining the
weight and for reading off the same while at the same time if desired to afford
means for rendering the weights in two or more standard national measures, such
as French and English measures.
According to this Invention I form the steel yard with two or more arms or
parts with intervening or adjoining space or spaces on the arms which need not
be graduated the sliding weights with tongues or pointers are placed, and in the
space or spaces I fit one or more fixed or moveable scale bars which may have
two three or more faces or sides or be cylindrical. By using a revolving scale bar
pivotted at each end and having two or more faces I obtain facility for indicating
the weight in two or more standard measures French and English.
By using a triangular square or hexagon revolving scale bar I may thus for
instance on each of the faces mark thereon different measures of weight, or on two
adjoining faces or on opposite sides of the same face have one scale for the tons,
cwts., or other large divisions of weight and on the other a scale for the quarters
pounds or other small divisions of weight. The other faces of the scale bar may
then be marked and divided correspondingly for French or other measures and
thus I may shew the total weight from the smallest divisions to the full load, in
any national standard, without using loose weights.
Stops or catches or other suitable appliances may be fitted to the end or ends
of the scale bar for retaining it in any of the desired portions. In order that my
Invention may be more clearly understood I will now refer to the accompanying
Drawings.

loosening the axes so that the scale bar may be removed when required, e e¹ are
the sliding weights on the arms 6 61; f is the stop or catch for securing the scale
bar in position when being used for any given denomination of weights. This
stop or catch may be of any convenient arrangement, it may be a simple stud
operated by a button as shewn at Figure 4, or it may be a weighted lever for
example as shewn at Figs. 1 and 3, or it may be of any other suitable construction
so that the graduated scale bar may be held in position when placed with the

page_text: required side uppermost. The scale bar may be arranged to have on one edge a
graduated scale of indicated weights in English and on the opposite side a
graduated scale in French so that when weighing anything the weight would be
indicated on the same surface and be seen at one glance in English and French
weights, thus rendering any calculation whatever unnecessary. There may be
more than two different scales in fact there may be as many different scales on
the steel yard bar as there are slides sides to the bar. As there are no sliding
weights on the scale bar the divisions and other indications thereon will not be
obliterated by wear as heretofore. The other parts of the machine are the same
as an ordinary steelyard weighing machine, such as those constructed by Henry
Pooley and Son.
Having now described the nature of my said Invention and in what manner
the same is to be performed I declare that I am aware that it has been proposed
to make steelyard bars with several scales engraved on one and the same bar and
to make revolving bars with counterweights bung upon them or sliding upon them.
L-lay-no-claim to such a bar-in itself It has also been proposed to make a steel-
yard in the form of an open frame with sliding weights on its graduated side
limbs; also to make a steelyard in the form of an open frame without gradua-
tions and wherein is mounted a rotatable polygonal graduated scale bar having
a shifting weight hung thereon I lay therefore no separate claim to an open frame
steel yard nor to a rotatable scale bar but I claim as my "Improvements in
and Connected with Steelyards for Weighing Machines."
First. The construction and employment of steelyards with a graduated index
bare supported at the ends and capable of being revolved and adjusted when
required so as to shew the weight in several standard measures at one and the
same time of weighing and without having the sliding weights or poises on
the graduated index bar but sliding on ungraduated arms of the steel yard
substantially as described and illustrated with reference to the accompanying
Drawings.
Second: The employment of one or more revolving or fixed-graduated or seale
bars applied to the steel yard so that the weights placed on different arms of the
steelyard may be indicated on the seale bar or bars all substantially as-hereinbefore
described-and-illustrated-in-the-accompanying Drawings
Third: The mode and means described for accomplishing the above and for
changing and adjusting the several positions of the scale bars substantially as set
forth together with any mere modification-thereof.
In witness whereof I the said John Chater have hereunto set my hand
and seal this Fifteenth day of July in the year of our Lord One thousand
eight hundred and eighty.

WEIGHING
The object of this Invention is to provide a ready means for ascertaining the
weight and for reading off the same, while at the same time, if desired, to afford
means for rendering the weights in two or more standard national measures, such
as French and English measures..
According to this Invention I form the steel yard with two or more arms or
parts, with intervening or adjoining space or spaces; on the arms, which need not
be graduated, the sliding weights with tongues or pointers are placed, and in the
space or spaces I fit one or more fixed or moveable scale bars which may have
two, three, or more faces or sides, or be cylindrical. By using a revolving scale bar
pivotted at each end, and having two or more faces, I obtain facility for indicating
the weight in two or more standard measures, say French and English.
By using a triangular, square, or hexagon revolving scale bar I may thus, for
instance, on each of the faces mark thereon different measures of weight; or on two
adjoining faces, or on opposite sides of the same face, have one scale for the tons,
cwts., or other large divisions of weight, and on the other a scale for the quarters,
pounds, or other small divisions of weight. The other faces of the scale bar may
then be marked and divided correspondingly for French or other measures, and
thus I may show the total weight from the smallest divisions to the full load in any
national standard without using loose weights.
Stops or catches, or other suitable appliances, may be fitted to the end or ends
of the scale bar for retaining it in any of the desired portions. In order that my
Invention may be more clearly understood, I will now refer to the accompanying
Drawings.
Figure 1 is a side elevation, Figure 2 is a plan, and Figure 3 is an end elevation
of a steelyard for weighing machines constructed according to my Invention. a is
the revolving scale bar; b, b¹, are the steel yard arms forming a frame for the
movable bar; c, c', are centres or cones on which the scale bar a is free to turn
when required; d, d, are nuts for adjusting the position of the scale bar a, and for
loosening the axes so that the scale bar may be removed when required; e, e¹, are
the sliding weights on the arms b, b'; f is the stop or catch for securing the scale
bar in position when being used for any given denomination of weights. This
stop or catch may be of any convenient arrangement; it may be a simple stud
operated by a button, as shewn at Figure 4, or it may be a weighted lever, for
example, as shewn at Figs. 1 and 3; or it may be of any other suitable construction,
so that the graduated scale bar may be held in position when placed with the
required side uppermost. The scale bar may be arranged to have on one edge a
graduated scale of indicated weights in English, and on the opposite side a
graduated scale in French, so that when weighing anything the weight would be
indicated on the same surface, and be seen at one glance in English and French
weights, thus rendering any calculation whatever unnecessary. There may be
more than two different scales, in fact, there may be as many different scales on the

the scale bar the divisions and other indications thereon will not be obliterated by
wear as heretofore. The other parts of the machine are the same as an ordinary
steelyard weighing machine, such as those constructed by Henry Pooley and Son.

the same is to be performed, I am aware that it has been proposed to make steel-

page_text: yard bars with several scales engraved on one and the same bar, and to make
revolving bars with counterweights hung upon them or sliding upon them. I lay
no claim to such a bar in itself, but I claim as my "Improvements in and Connected

First. The construction and employment of steelyards with graduated index
bars supported at the ends, and capable of being revolved and adjusted when
required so as to shew the weight in several standard measures at one and the

bars applied to the steel-yard, so that the weights placed on different arms of the
steelyard may be indicated on the scale bar or bars, all substantially as hereinbefore
described and illustrated in the accompanying Drawings.
Third. The mode and means described for accomplishing the above, and for
changing and adjusting the several positions of the scale bars, substantially as set
forth, together with any mere modification thereof.
In witness whereof, I, the said John Chater, have hereunto set my hand
and seal, this Fifteenth day of July, in the year of our Lord One thousand
eight hundred and eighty.
