PROVISIONAL SPECIFICATION.
Improvements in or connected with Steelyards for Weighing
Machines or like purposes.
I, HENRY POOLEY, Junior, of 29 and 31, Manchester Street, Liverpool, in the
County of Lancaster, Engineer, do hereby declare the nature of this invention to
be as follows
--
This invention relates to that class of steelyards of weighing machines which are
employed in connection with weighbridges, platform, and other like weighing
machines, and has for its object to provide in connection with such weighing
machines means whereby two or more different standards of weight, or codes, or
values, may be presented, and which may be capable of being determined or indicated
by one steelyard bar.
According to this invention there is provided in connection with a steelyard, a
sliding main weight counterpoise, and a revolving or movable graduated index bar
mounted on the steelyard in such a manner that it can be turned. This index bar
may be of any suitable section-such as cylindrical, square, triangular, or other
suitable section and is provided on its respective edges or sides with notches, and
scale graduations for different weights; for example, the edges of the bar may be
notched and graduated for three different weights-such as English, French, and
Spanish and by turning the index bar by a ratchet or equivalent gear the scale
of graduations intended to be used may be placed uppermost or so as to be read
with facility.
The sliding counterpoise may be of the type described in the Specification of
Letters Patent No. 13642 of 1885 granted to Henry Pooley, and is provided with
a means of determining the aliquot parts of the main divisions of weight which are
marked on the revolving index bar. This means may consist of a weight sliding
on a bar on the counterpoise and having a finger or fingers which can be set
opposite to any division of a minor scale of weight corresponding to the graduations
on the index bar, and which is attached to the side of the sliding counterpoise, or
the counterpoise may be provided with a revolving index bar and a sliding weight
graduated with minor scales to correspond with the graduations on the main
revolving index bar.

COMPLETE SPECIFICATION.
Improvements in or connected with Steelyards for Weighing
Machines or like purposes.
I, HENRY POOLEY, Junior, of 29 and 31, Manchester Street, Liverpool, in the
County of Lancaster, Engineer, do hereby declare the nature of this invention, and
in what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
This invention relates to that class of steelyards of weighing machines which are
employed in connection with weighbridges, platform, and other like weighing
machines, and has for its object to provide in connection with such weighing
machines, means whereby two or more different standards of weight, or codes, or
values, may be presented, and which may be capable of being determined or indicated
by one steelyard bar.

page_text: According to this invention, there is provided in connection with a sliding main
weight counterpoise, and a revolving or movable graduated index bar mounted on
the steelyard in such a manner that it can be turned. This index bar may be of
any suitable section-such as cylindrical, square, triangular, or other suitable
section and is provided on its respective edges or sides with notches, and scale
graduations for different weights; for example, the edges of the bar may be notched
and graduated for three different weights such as English, French, and Spanish-
and by turning the index bar, by a ratchet or equivalent gear, the scale of
graduations intended to be used may be placed uppermost, or so as to be read with
facility.
The sliding counterpoise is by preference of the type described in the Specification
of Letters Patent No. 13642 of 1885 granted to Henry Pooley. This weight is
provided with means of determining the aliquot parts of the main divisions of
weight which are marked on the said revolving index bar, and this means may
consist of a weight sliding on a bar fixed on such counterpoise and having a finger
or part which can slide over or opposite the divisions of the minor scale of weights
thereon, whose graduations correspond in kind with those of the main index bar:
Or, this main counterpoise weight may be provided with a revolving index bar
constituting a minor weight scale provided with graduations, and having a minor
weight adapted to slide thereon.
In the drawings which serve to illustrate this invention,
Figure 1 is a side elevation of the steelyard provided with improvements accord-
ing to this invention.
Figure 2 is a cross section of same.
Figure 3 is a detail illustrating the particular construction and
the revolving index bar shewn in Figures 1 and 2; and
Figure 4 is a cross section through same..
arrangement of
Referring now to the drawings, A designates the steelyard; B is the sliding
counterpoise thereon; C is the revolving index bar; D is the scale of the minor
division of weight; and E is the sliding weight used in connection therewith. It
will be seen the revolving index bar C is, in the example shewn in the drawings,
of circular form in cross section, and that it lies in a semi-circular groove in the
upper edge of the steelyard A. The counterpoise B is borne by the upper part of
the revolving index bar C, its weight at one end being taken by a roller b', whilst at
the other end the weight is taken by the short end of the disengaging lever 3 of
the actuating handle .
The scale D for determining the aliquot parts of the main divisions of weight is
supported, in the example shewn, by the studs a', and the weight used in connection
with this scale is provided at the back with a recess and slot, d², corresponding with
the shape of the scale itself, and slides freely thereon.
The index bar C is mounted and kept in position by centres c¹ c², the centre c¹
being supported by a carrier or holder pinned to the steelyard A. This centre is
threaded at one end and has on it a nut f¹. By turning this nut one way or the
other, the centre e¹ can be withdrawn from its holder for pushed back into it, and
by this mechanism the index bar can always be kept properly adjusted on the
steelyard.
The bar C is rocked or moved about its axis by the handle h, which has within
it a pawl pressed outwards by a spring follower 2, and which engages with
three teeth on the end of the bar c, this bar at this part being reduced in size
to pass through the handle h. By this device, by rocking the handle h in one
direction until the pawl ' engages with one of the said teeth i, and then rocking
it back to the vertical position, one of the scales on the bar e will be brought
uppermost.
The scales on the bar C are provided as shewn in the drawings; that is to say,
each division of weight is marked off by a notch c, against which the numeral
representing the weight corresponding with each notch is provided. The sliding
counterpoise B engages with said notchies by a corresponding knife-edged

page_text: projection provided on the extended portion thereof, and adapted to fit into
them. In setting the sliding counterpoise B in the act of weighing, the lever 6³ is
pressed in towards the actuating handle by the weigher, and the short end of the
lever resting upon the bar C being thereby depressed, the projection of the
part is raised out of the notch with which it is engaged, and it (the weight B)
may then be moved to any notch corresponding with the weight (this is the major
division of weight) of the goods or thing being weighed. This having been done,
the aliquot parts of the main weight, above that given by the main weight, are
determined by moving the minor weight E along the scale D until equipoise is
established, the part of the scale lying coincident with the projecting portion & of
this weight being that from which the weight is read.
The main weight scale C in the example shewn in the drawings is divided into
three scales, namely, Half-tons, 500 Kilogrammes, and Cantars; whilst the
scale bar D of minor weights is divided into three corresponding scales of Cwts.,
50 Kilogrammes, and Rottolis. Thus, either of these three scales can be used
at will, and the weight of the goods so weighed computed and read off on any or
either of them.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, it is to be understood
that this invention is not confined to the particular construction of parts set forth
with reference to the figures of the drawings, as these may be modified and the
invention carried out in different ways without departing from the controlling
features of the invention, but I declare that what I claim is :-
1. In a weighing machine, the combination with the steelyard of a revolving or
movable scale or index bar, of circular, triangular, or other form, and with which
the sliding counterpoise is adapted to engage, and arranged in connection with said
steelyard, substantially as and for the purposes set forth.
2. In a weighing machine, a revolving or movable index bar, of circular, triangular,
or other form in cross section, and arranged on the top of said steelyard substantially
as set forth.
3. In a weighing machine having a steelyard and a sliding counterpoise operating
in conjunction with a notched index bar, the combination with said counterpoise of
a scale for the minor divisions of weight (D), and a weight (E) arranged and sliding
thereon in the manner set forth.
4. In a weighing machine having a revolving or a movable index bar arranged
in connection with the steelyard thereof, the means substantially as set forth with
reference to the drawings by which said index bar is rocked or rotated.
