I JOHN CLAYTON MEWBURN, of 169 Fleet Street, in the City of London, Fellow
of the Institute of Patent Agents do hereby declare the nature of my invention for
"IMPROVEMENTS IN WEIGHING MACHINES FOR THE FEED APPARATUS OF CARDING
OR OTHER MACHINES" to be as follows:-
This invention bas reference to the weighing machines employed in connection
with the feeding or charging apparatus of carding, batting or other machines. In
these weighing machines (in the Tatham machine for example) the basket or
receptacle which contains the wool or fibrous material while being weighed is
supported at two points of the lever which constitutes the beam of the machine
and is loaded with a weight to weigh the successive charges of fibrous material.
This suspension of the basket or receptacle at two points has the objection that
irregular distributions of the material in the basket cause the beam to be balanced
by unequal charges; these variations in the weighing produce irregularities in the
work of the batting, carding or other machine in connection with which the
weighing machine is employed.
Now the object of the present invention is to overcome this objection and the
invention consists in making the basket or receptacle independent of the lever or
beam and in having only one point of suspension of the basket to the lever.
According to one way of carrying the invention into effect the basket rests by a
knife edge on a piece fixed to the lever or beam which itself is free to oscillate on
a knife edge on a fixed support. The weight is placed on the lever or beam at the
opposite side of the fulcrum to the basket. Or the basket may be supported by
two chains connected at their upper ends to a link or cap which rests on a knife
edge on the beam, the beam being as before free to oscillate on a knife edge on a
fixed support. The basket or receptacle may be made to discharge its contents
either by opening the bottom or by tilting; in the former case the hinges or joints
on which it is opened may be at the top or at a suitable point between the top and
bottom.

I, JOHN CLAYTON MEWBURN, of 169 Fleet Street, in the City of London, Fellow
of the Institute of Patent Agents do hereby declare the nature of this invention
(a communication from abroad by David Girrès of St Martin, Ardennes, France,
Spinner) and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
"
This invention has reference to the weighing machines employed in connection
with the feeding or charging apparatus of carding, batting or other machines. In
these weighing machines (in the Tatham machine for example) the basket or
receptacle which contains the wool or fibrous material while being weighed is
supported at two points of the lever which constitutes the beam of the machine
and is loaded with a weight to weigh the successive charges of fibrous material.
This suspension of the basket or receptacle at two points has the objection that
irregular distributions of the material in the basket cause the beam to be balanced
by unequal charges; these variations in the weighing produce irregularities in the
work of the batting, carding or other machine in connection with which the
weighing machine is employed.
Now the object of the present invention is to overcome this objection, and the
invention consists in making the basket or receptacle independent of the lever or
beam and in having only one point of suspension of the basket to the lever.
According to one way of carrying the invention into effect the basket rests by a
knife edge on a piece fixed to the lever or beam which itself is free to oscillate on
a knife edge on a fixed support. The weight is placed on the lever or beam at the
opposite side of the fulcrum to the basket. Or the basket may be supported by
two chains connected at their upper ends to a link or cap which rests on a knife
edge on the beam, the beam being as before free to oscillate on a knife edge on a
fixed support. The basket or receptacle may be made to discharge its contents
either by opening the bottom or by tilting; in the former case the hinges or joints
on which it is opened may be at the top or at a suitable point between the top and
bottom.
The annexed drawings represent several ways of carrying out the invention. In
Figure 1 the basket A rests (at each side) by a single knife edge N on a piece F
fixed to the lover or beam C which is itself free to oscillate on a knife edge D on a
fixed support E. B is the weight on the lever C. In order to discharge the
contents of the basket A it is opened at the bottom, the hinges or joints being at
the top. In Figure 2 the basket A is supported by two chains O, O connected at
their upper ends to a link or cap S which rests on a knife edge N on the beam C.
As in Figure 1 the contents of the basket are discharged by opening it at the
bottom but the hinges or joints are near the bottom at X, X. In the modification
shown in Figures 3 and 4 the contents are discharged by the tilting of the basket.
A pin G on the basket A passes through a piece fixed to the lever C; the pin G is
connected by a link H to a pin I on the lever; the basket is tilted upon the pin G
by the arm K K¹ which when the basket is full is caused, by means of ordinary

page_text: mechanism composed of a pin wheel acting on a cam on the tail of the arm to bear
on the suitably curved piece L fixed to the basket by a bent arm M the arm K K¹
moving on the centre K³. After the contents have been discharged the basket
returns to its normal position under the action of the weight B, the arm K K like-
wise returning to its normal position under the action of a counterweight. In this
modification the basket has likewise only one point of suspension on the lever or
beam C.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, as communicated to
me, I declare that what I claim, in respect of weighing machines for the feed
apparatus of carding or other machines, is
1. Constructing such machines with the basket or receptacle independent of the
lever or beam and with only one point of suspension on this beam substantially as
and for the purpose herein before described.
2. The several arrangements represented respectively in Figures 1, 2 and 3, and 4
and bereinbefore described.
