COMPLETE SPECIFICATION.
A Portable Elevator and Weighing Machine on Castor Wheels for
Casks of Dry Goods, Barrels of Liquids, Sacks of Corn, or any
other Package of Goods.
JOHN HART HOPE trading as J. Hartope & Co. General Merchants Leicester
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 :-
A weighing apparatus with travelling frame on castor wheels that passes over
the article to be weighed by means of a horizontal bar or bars supported by two or
more legs on swivel wheels, carrying steel yard or other weighing apparatus. The
object to be weighed is elevated by means of a lever-worked by hand-wheel &
screw and gripping apparatus which is made adjustable to the size of the article
to be weighed by means of a hand wheel working on a screw and locking the arms
of, the gripping apparatus round a small or large object-as shown in design-full
description of which follows:-
AA (Figures I, II, III, IV,) are two pieces of channel iron bent to an arch and
one super-imposed diagonally over the other.
B (Figures I, II, III, IV,) is a malleable cast lever pivotted in the proportion
of 2 to 1.
C (Figures I, II, III, IV,) is a casting bolted on to A. & forming the bearing
for B.
D. (Figures I, II, III, IV,) is a wrought iron forging bolted to A, and A to
tie them.
E (Figures I, II, IV,) is a link depending from & swivelling in a block pivotted
in B the bottom end of this link forms the pan in which one knife edge of the
steelyard works, the link should be of wrought iron with a piece of steel welded in
to form bearing for knife edge & the bearing surface should be hardened.
The knife edges should be of faggoted iron & a piece of steel welded in to form
the bearing surface.
F Figures I, II, III, is the steelyard arm this should be a casting of steel in one
piece, & cored out so that the link E may hang inside it, this construction will
enable the centres of the steelyard to be nearer together than if both E, & H,
(Figures I, II, & V) were outside & this is a matter of great importance. The
[Price 8d.)

page_text: centres are 13" apart the changeable weights for 1 ton equal 90 lbs. & these are
hung 43.55" from the centre. The ball for scaling minor differences in weight
weighs 3 lbs., the zero is 7" from the centre & the steel-yard arm is divided into
56 divisions, to 56 lbs. occupying a length of 311". equalling 1 lb.
It will be seen from the drawing that when a barrel of the size shown is in the
machine a man would have great difficulty in reaching the ball if it were at the
above zero owing to the barrel being in the way & I think it is perhaps better to
be content with only 28 lbs. on the steelyard arm & these divisions should occupy
the outer 15" of the steelyard arm, the zero would then be at point Z (Figures I)
and consequently the ball always in a come-at-able position, the ball would of
course be of the same weight as in the other case.
G (Figures 1, II, III, & V.) is a cast iron hand wheel screwed in the cogg and
working on the screw H. (Fig. 1, II, & V) by its means the arms S S (Figures I,
II, III & V) are locked either round a large or small barrel, or either, or both of
the arms S S (Fig. I, II, III & V) may be locked open by this arrangement so
that the machine may be brought over the barrel, to be weighed the arms S S
(Fig. I, II, II & V) are locked for that purpose in such a position as that their
lowest point is no lower than the bottom of the links R R (Figs. I, II, III, & V):
H (Figs. 1, II, & V) is a wrought iron screw, forked at its upper end to
embrace (Figs. 1, II, & III) and in this fork are the openings in which one"
knife edge works there should be a piece of steel welded in F (Figs. I, II & III)
to form the surface in contact with the knife edge & this should be hardened.
III (Figures I, II, III,) are three stretchers made of light channel iron.
K (Figures I, II, III,) is a wrought iron bar taking the place of a fourth
stretcher and forming the support for the steel-yard arm the bottom of K (Figures I,
II, III,) is 5.8" from the ground & the man weighing would pass under the
bar to manipulate the ball for this purpose there is no stretcher at this end of the
machine the brackets which support K (Figs. I, II, III,) should for that reason be
rigid.
L (Figures I, III,) is a piece of wrought iron bolted to K (Figures I, II, III;)
to form guide for F (Figs. I, II, III,) & prevent it going up too high.
M M (Figures I, II, III,) are two cast iron right & left hand brackets bolted
to A A (Figs. I, II, III & IV) & K (Figures I, II, III).
O (Figures I, II, III, IV) is a screw 3" pitch 3 threads this screw would require
a force of about 18 lbs. to be exerted on the hand wheel fast on O (Figs. 1, 11,
.II, IV). The handles are at radius of 64".
"
Q (Figs. I, II, III, IV,) a cast iron bracket bolted to A (Figs. I; II, III, IV,)
& forming point of resistance for P (Figures I, II, III, IV).
R R (Figs. I, II, III; V,) two wrought iron links.
SS (Figures I, II, III, & V) two malleable cast iron gripping arms for raising
the barrel to be weighed.
TT (Figs. I, II, III, IV,) four right & left hand malleable cast iron brackets
bolted to AA (Figs. I, II, III, IV) & having a boss in which, the castors V V
(Figs. I, II, III, IV) swivel,
UU (Figs. I, II, III, IV,) four cast malleable iron, brackets for castor
wheels VV (Figs. I, II, III, IV).
W. (Figs. I, III,) changeable weights to hang to K (Figs. I, II, III,) those
weigh 90 lbs. to 'I ton.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what 'I
claim is
i
1. An improvement combining a steelyard or other weighing apparatus with
travelling frame on castors or wheels. The apparatus being arranged to run over
a row of barrels or other packages-to elevate each article by means of a lever and
gripping, apparatus and weigh same; instead of as usual moving the article to be
weighed to the weighing machine.
'

page_text: 2. Introducing for the first time arms that are made to grip the article to be
weighed by means of a hand-wheel (screwed in the bore) and working on the screw
so that by its means the arms are locked round the object to be elevated and
weighed. The same hand wheel making gripping arms so adjustable as to lock
round a small or large object.
3. An arrangement whereby either or both of the gripping arms referred to
above in Claim No. 2, may be locked open so that the machine may be brought over
the article to be weighed end-ways or side-ways. The extremities of the arms
when locked open being no lower than the centre from which they hinge. The
arms will thus clear the object it is desired to weigh.
