Improvements in Weighing Scales or Weighing Machines,
I, WALTER ASTON HANDLEY, of Bright Holme, Manchester Road, Broadheath,
Altrincham, Cheshire, Grocer, do hereby declare the nature of this invention
to be as follows:-
My said invention relates to improvements in weighing scales for weighing and
indicating without the use of loose weights.
In a weighing machine constructed according to my said invention the beam is
provided at one end with a pan or other receptacle and engages at its other end
with weights of various sizes. Each weight is provided with a staple or a slot
or other clearance through which the beam can freely move until the weight is
brought to bear on the beam.
In order to support or hold up clear of the beam those weights which are
not required I provide lifting and lowering levers. These levers fulcrumed on a
cross har are connected with knobs or handles or other suitable attachments for
raising or lowering the ends of the levers which hold up the weights. By these
means it is possible to bring any one or more of the weights to bear on the
scale beam by removing its support. Attached to the end of each lever is a
wire connected at its other end with a tablet or ticket. These tablets or tickets
are exposed through an aperture when any of the levers are lowered and indicate
the weight on the scale pan.

Improvements in Weighing Scales or Weighing Machines.
:
I, WALTER ASTON HANDLEY, of Bright Holme, Manchester Road, Broadheath,
Altrincham, Cheshire. Grocer, 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:-
This invention consists of improvements in weighing scales or weighing machines
for various services, my objects being to provide for the convenient and accurate
weighing of the required articles without the use of loose weights, and for the
effective displayal or indication of the result of the said weighing.
In the three accompanying sheets of explanatory drawings to be hereinafter
referred to.
Figure 1 is a sectional side elevation representing the application of my inven-
tion to a scale or machine of one type. Figure 2 is a sectional end elevation of
one half of the scale or machine on the line a b Figure 1,

page_text: Figure 3 is a plan of the scale beam.
Figure 4 is a side elevation illustrating the application of my invention to
a scale or weighing machine of another type, whilst Figure 5 is a plan showing
parts comprised by my invention.
The samé reference letters in the different views indicate the same parts.
Referring to Figures 1, 2, and 3, the beam A is provided at one end with »
pan as B and is arranged at its opposite end for engagement with weights as C
of varying sizes. The connection between each weight and the beam is formed
preferably by means of a staple or shackle as I through which the beam, or a
hooked projection, such as A, from the same, can be freely moved until it is
brought to bear against the closed end of the shackle and so caused to sustain
the weight.
The weights are normally sustained, when not required for the actual weighing
operation, by means of levers such as E, one such lever being provided for each
weight. The whole of the levers are fulcrummed on the common pivot or
cross bar F, and each lever is preferably forked at the end away from the
weights C, and caused to embrace an eccentrically mounted disc G as illustrate:l.
the said disc being provided with an operating arm H having a knob or head
projecting through a slot in the casing as shown. Thus for each separate weight
arranged for engagement by the beam A as required, there is a lever as E, and an
eccentrically mounted disc G, with operating arm H.
For the purpose of weighing the article or articles placed in the pan B, the
required number of arms as H are depressed to move the levers as E to the
position shown by dotted lines, and thus to cause a number of the weights C
to become suspended from the beam A until the load in pan B is exactly balanced
or weighed.
For the purpose of indicating or displaying the result of the weighing, I
attach to that end of each lever E which is adjacent to the weights C, a wire
or thin rod such as which is connected at its upper end with a tablet or ticket K.
The complete series of such tablets or tickets are arranged within a raised portion
of the casing of the machine as shown, and they each bear the proper figure,
figures, or letters indicating the value of the weight with which they are con-
nected. On the depression of any arm as H the corresponding tablet or ticket
will descend in front of one of the sight apertures L, and thus can be readily
seen by the purchaser and also the operator or attendant.
In the example of the application of my invention shown at Figures 4 and 5.
the scale pan 1 has a system of supporting beams A arranged in any ordinary
manner. From the upper beams the holder M is suspended and upon such holder
the varying sized weights C¹ are supported during the time that they serve to
counter-balance the pan B1 and its contents during the act of weighing.
But the said weights are normally suspended, clear of the holder M, by the
levers as pivoted on the bracket N. The end of each lever N away from the
weights C is curved as shown and in connection therewith an operating arm H
is arranged fulcrummed upon a pivot pin or cross-bar . A small roller as h
is mounted upon each arm H', to serve as an abutment for the weighted lever N.
When it is desired to bring any weight C to bear upon the holder M for the
purpose of weighing, the required arm H' is depressed and thus as the roller h
mounted thereon is carried with it to the position indicated by dotted lines, the
curved end of the lever N adjacent thereto will be free to rise, under the influence
of the weight at its opposite end, to the dotted line position shown at Figure 4,
in which position its weight C¹ will become entirely supported by the holder M.
The indication or displayal of the value of the weights employed for any
weighing, is effected by tablets or tickets as K, in the manner hereinbefore
described, the connection between a tablet or ticket and the corresponding
operating arm H' being effected through the links k¹.
After each weighing the whole of the depressed arms (H) are elevated simul-
taneously and their corresponding weights (C') raised from the holder M, by a

page_text: turning movement of the lever P (Figure 5) fixed to the aforesaid pivot pin
or cross bar 0. On such movement a projection 9 from a disc Q (one of which is
provided for each arm H¹) raises the adjacent arm H₁ and thus by returning it
to its normal position, causes the roller to depress the adjacent curved end of
the lever N and so raise the corresponding weight C¹ from the holder M.
In each of the scales or weighing machines illustrated, the particular weight
controlled by each arm H or H is clearly indicated upon the knob or head of
such arm which projects through the casing in a position convenient for access.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
1. In weighing scales or weighing machines, means for weighing without the
use of loose weights.
2. In weighing scales or weighing machines, the combination with means for
weighing without the use of loose weights, of means for indicating or displaying
the result of the said weighing, substantially as described.
3. The improved weighing scales or weighing machines constructed and
arranged substantially as and for the purposes described and as illustrated.
