Improvements in or connected with Machines for Weighing Heavy
Bodies, such as Railway Rails.
I, JOHN CILATER, of Henry Pooley and Son, Limited, of 89 Fleet Street, in the
City and County of London, Mechanical Engineer do hereby declare the nature
of this invention to be as follows:-
Hitherto in the weighing of heavy bodies, such as railway rails and such
objects, it has been necessary to know the weight of when placed in position, and
again when removed from the position they have occupied, and thereby to ascertain
by calculation the amount of depreciation which has taken place per yard during
the time they have been in position, now the essential object of my invention is
the production of a machine that will mechanically accomplish this end.
According to my invention I arrange on one end, say the tail end of the beam
or balance of a steel yard, an indicator, capable of being slidden thereon, and
along or over a scale, on which is marked figures to indicate the total loss per rail.
The indicator has an index finger, which passes across a proportional diagram,
which is formed say on a plate, fitted, or engraved upon the vertical face of the
beam, that is on the same side of the fulcrum, us the rail to be weighed is
suspended, when the proportional diagram is on the tail end of the steel yard.
On the other side of the fulcrum there is a sliding poise, indicating upon the usual
scale, and at the end of the beam or steel yard, there is a scale pan.
The diagram is composed of a number of parallel horizontal lines, to indicate
the length of the rails, say from 20, to 32, feet, and these lengths are shewn upon
vertical lines, which bound both sides of the diagram, the aforesaid parallel
horizontal lines being drawn across and joining them.
In the aforesaid diagram, the bottom horizontal line is divided into a number
of divisions say 19, and the top horizontal line which is of equal length is divided
into say 12 numbered divisions, lines being drawn from like numbers on the top,
to like numbers on the bottom. Supposing that there is a total loss of 12 lbs. per
yard in a rail we get a total loss, in a rail of 20 feet long, of 81 lbs. It follows
then that diagonal lines drawn from 0 to 12, on the bottom line intersecting the
horizontal lines on the diagram will show the loss per yard, for any rail from
20 feet to 32 feet long.
When weighing a worn or used rail, weights must be placed on the scale pan,
and the poise set to the weight which it is known the rail should or ought to be.
The slide carrying the index finger is then moved until the rail exactly balances,
and the total loss is read by the scale; if say a 24 ft. rail is being weighed, and
the total loss is 604 lbs., as indicated by the index finger on the scale, then follow-
ing the line of the index finger till it intersects the horizontal line drawn from
24 to 24, it will be found that it scarcely touches the diagonal line drawn from
8 to 8, thus showing a loss of about 8 lbs. per yard.
The proportional diagram may be on either end of the steel yard.
Machines constructed according to my invention can be conveyed from place
to place and consequently used for weighing the same rails at different periods.

page_text: Although I have described the invention as applied to the weighing railway
rails, yet it will be understood that the same is equally applicable to other bodies,
where it is required to ascertain the difference in weight of such body, at
different periods.

Improvements in or connected with Machines for Weighing Heavy
Bodies, such as Railway Rails.
I, JOHN CILATER, of Henry Pooley and Son, Limited, of 89 Fleet Street, in the
City and County of London, Mechanical Engineer, do hereby declare the nature
of this invention and in what manner the same is to be performed to be par-
ticularly described and ascertained in and by the following statement :-
Hitherto in the weighing of heavy bodies, such as railway rails and such
objects, it has been necessary to know the weight of same at the time when they
have been placed into position, and also the weight when removed from the
position they have occupied, and thereby to ascertain by calculation the amount
of depreciation which has taken place per yard or other unit during the time such
objects have been in position.
Now the essential object of my invention is the production of a machine that
will mechanically assist in accomplishing this end, and in order that my said
invention may be readily understood I will now describe same with reference to
the accompanying drawings, whereon Fig. 1 shews my improved weighing
machine in side elevation, and Fig. 2, is an enlarged view of a diagram which
is formed, fitted, or engraved upon a part of the weigh beam.
According to my invention I arrange upon one end, say the tail end A of the
bean or balance of a steel yard, an indicator B capable of being slidden thereon,
and acting somewhat similar to a sliding poise. This indicator B can be passed
along or over a scale C, on which is marked figures to indicate the total loss per
rail.
The indicator B has an index finger D which passes across a proportional
diagram C, which is formed or engraved, say on a plate fixed to the vertical face
of the beam. The proportional diagram C is on the same side of the fulcrum A¹
as the rail to be weighed is suspended, that is to say the proportional diagram is
on the tail end of the weigh beam. On the other side As of the fulcrum A¹
there is a sliding poise E, indicating upon the usual scale, and suspended at the
end of the beam or steel yard there is a scale pan F.
The proportional diagram C referring more particularly to Fig. 2 is composed
of a number of parallel horizontal lines C to indicate the length of the rails or
other objects, say from 20 to 30 feet, and these lengths are indicated upon vertical
lines which bound both sides of the diagram C', the aforesaid parallel horizontal
lines being drawn across and joining the lines C
In the aforesaid diagram the bottom horizontal line C is divided into a number
of equal divisions say 19, by lines radiating from a common centre (not shewn),
and the top horizontal line C, is as shewn consequently divided into 12 divisions,
the radiating lines C extending from like numbers on the top to like numbers
on the bottom; the points at which the lines intersect the horizontal line C
on the diagram are points from which a vertical line, given by the index finger D,
shew total loss on the scale C of the particular rail or object being weighed."

In order to find the loss per yard in lbs. of the rail being weighed, the length of
the rail being ascertained, a horizontal line C corresponding on the index
the length of such rail, is traced to the index finger D, the radial line C inter-
secting the selected horizontal line C³ at or near such index finger is then traced
either to the line C or to the line C and the numbers there found give the loss
per yard in pounds.
When for example weighing a worn or used rail, weights must be placed on
the scale pan F and the sliding poise E set to the weight which it is known the
rail had originally been. The slide carrying the index finger D is then moved
until the rail exactly balances, and the total loss is read by the scale C. Thus,
if say a 24 ft. rail is being weighed, and the total loss is 56 lbs., as indicated by
the index finger D on the scale C, as shewn in the drawing at Fig. 2, then follow-
ing the line of the index finger till it intersects the horizontal, line drawn from
24 to 24 it will be found that it touches the radiating line C, drawn from 7 and 7
thus shewing a loss of 7 lbs. per yard on the scales marked C or C³.
The proportional diagram may be on either end of the steel yard.
Machines constructed according to my invention can be conveyed from place
to place and consequently used for weighing the same rails or other articles at
different periods.
Although I have described the invention as applied to the weighing of railway
rails yet it will be understood that the same is equally applicable to other bodies,
where it is required to ascertain the difference in weight of such bodies at different
periods; also the arrangement of scales and intersectional lines may be varied for
convenience of reading, and for shewing different denominations or measures.
It is obvious that the weighing machine as described may be employed as an
ordinary weighing machine."
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is:-
1. In machines for weighing heavy bodies, such as railway rails and other
articles, the employment thereon of a proportional diagram in combination with a
sliding indicator poise with an index finger, whereby the amount of depreciation
in weight may be readily ascertained, substantially as set forth.
2. The general arrangement of parts composing the improved machine fer
weighing and for ascertaining the amount of depreciation in weight of heavy
bodies such as railway rails and other articles, all constructed and acting sub-
stantially as and for the purposes described and illustrated with reference to the
accompanying drawings.
