page_text: LETTERS PATENT to Henry Dean Denison, of No. 17, Brunswick Street;.
Leeds, in the County of York, Weighing Machine Maker, for the Inven-
tion of "IMPROVEMENTS IN THE CONSTRUCTION OF SUSPENDING WEIGHING.
MACHINES APPLICABLE TO CRANES AND OTHER LIFTING APPARATUS."
Sealed the 13th July 1860, and dated the 11th February 1860.
PROVISIONAL SPECIFICATION left by the said Henry Dean Denison,
at the Office of the Commissioners of Patents, with his Petition, on
the 11th February 1860.
I, HENRY DEAN DENISON, of No. 17, Brunswick Street, Leeds, in the
County of York, Weighing Machine Maker, do hereby declare the nature
of the said Invention for "IMPROVEMENTS IN THE CONSTRUCTION OF SUSPENDED
WEIGHING MACHINES APPLICABLE TO CRANES AND OTHER LIFTING APPARATUS," to.
be as follows:-
My Invention relates to an improved combination of machinery or apparatus
to be hung on to the chain of a crane, Goliah sheave blocks, or other lifting
apparatus, by which the weight of any merchandise or material may be ascer-
tained whilst it is suspended, and the tare of which will be indicated by the
machinery or apparatus.
In performing my Invention I make use of a rectangular frame, within.
which are three or other suitable number of levers, connected together by and
working on knife-edge centres; one of these levers is connected to the indi-
cating lever, and the indicating lever has a setting-off lever for ascertaining

page_text: the tare. The indicating and setting-off levers are provided with pointers in
the usual manner, and with an adjustable ball on a screw, to counterbalance the
weight of the hooks, slings, or other tackle required. The rectangular frame
is suspended to the crane or other lifting apparatus by a loop or bridle, and
the hook for the attachment of goods or merchandise to be weighed is suspended
to one of the levers.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Henry Dean Denison in the Great Seal Patent Office on
the 2nd August 1860.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
DEAN DENISON, of No. 17, Brunswick Street, Leeds, in the County of York,
Weighing Machine Maker, send greeting.
WHEREAS Her most Excellent Majesty Queen Victória, by Her Letters
Patent, bearing date the Eleventh day of February, in the year of our Lord
One thousand eight hundred and sixty, in the twenty-third year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Henry Dean Denison Her special licence that I, the said Henry
Dean Denison, my executors, administrators, and assigns, or such others as I,
the said Henry Dean Denison, my executors, administrators, and assigns, should
at any time agree with, and no others, from time to time and at all times
thereafter during the term therein expressed, should and lawfully might
make, use, exercise and vend, within the United Kingdom of Great Britain
and Ireland, the Channel Islands, and Isle of Man, an Invention for "IM-
PROVEMENTS IN THE CONSTRUCTION OF SUSPENDED WEIGHING MACHINES APPLICABLE
TO CRANES AND OTHER LIFTING APPARATUS," upon the condition (amongst others)
that I, the said Henry Dean Denison, my executors or administrators, by an
instrument in writing under my, or their, or one of their hands and seals,
should particularly describe and ascertain the nature of the said Invention,
and in what manner the same was to be performed, and cause the same to
be filed in the Great Seal Patent Office within six calendar months next and
immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the. said Henry Dean Denison, do hereby
declare the nature of my said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement (that is to say) :-
:-
The nature of my Invention consists in an improved combination of

page_text: machinery or apparatus to be hung on to the chain of a crane, Goliah
sheave blocks, or other lifting apparatus, and by which the weight of any.
merchandise or material may be ascertained whilst it is suspended, and the
tare of which will be indicated by the machinery or apparatus.
And in order that my Invention may be fully understood and readily
carried into effect, I will proceed to describe the accompanying Sheet of
Drawings, reference being had to the figures and letters marked thereon.
Fig. 1 is an elevation of my improved machinery; Fig. 2 is a section.
through the same; Figs. 3, 4, and 5 are detached views of parts of the same:
and. Fig. 6 is an elevation of the whole apparatus as suspended to the jib of
a crane. A, a rectangular frame of flat iron, having a strong plate of iron.
fitting accurately within and on both sides, so as to form a hollow box; B, the
bridle or loop for suspending the whole apparatus; C, the hook for attach-
ment of goods to be weighed; D, D', and D2, the internal levers, working on.
knife-edge centres and steel bearings. These levers are pressed open or split
at one or both ends with the bearing working in the cleft. E, the indicating
lever for ascertaining the weight of the merchandise in hundredweights and
quarters; this lever is connected to the lever D2 by the link D. F, the
taring lever, for setting off the weight of a box or package which contains
goods to be weighed. Both these levers are provided with setting-off weights
and pointers in the usual manner, but I prefer forming transverse grooves at
each division marked upon the indicating lever. The moveable weight E'
upon the indicating lever is furnished with a detent fitting into the grooves,
thereby ensuring accuracy of movement and retention of the weight in its
place until the completion of the operation of weighing. F' is the indicator
in pounds of the merchandise to be weighed. This indicator is a prolongation
of the taring lever F, and is furnished with a sliding weight F². G, the ball
on the screw, projecting from the lever F, for counterbalancing the weight of
the slings, hooks, and other tackle hung on at C; H, the suspension bolt,
passing through the outside frame or bridle B, to which the lever D is con-
nected by the braces J; I, I, are front and back plates fitting in the frame A.-
When the apparatus is in operation, as shewn in Fig. 6, the frame A is
suspended between the merchandise or other material to be weighed and the
chain of the crane or other lifting apparatus, and as soon as the weight of
the slings or hooks has been compensated for by varying the position of the
weight G, and the known weight of the cask or packing case containing the
merchandise or other material to be weighed has been set off on the
taring lever F, the weight of the merchandise or other material can be ascer-

page_text: tained, as above described, by varying the positions of the sliding weights E
and F⁹.
I wish to remark that I do not limit myself to the use of the three levers
D, D', and D2, as more or less may be used. I would also remark, that the
graduated indicating lever E, although shewn. above the frame A, may be
placed to one side, in which case the upper lever D³ would have to be bent.
downwards and brought through the side of the frame to form the connection
with the indicating lever, or the connection may be made in any other
convenient manner.
Having thus stated the nature of my Invention, and described the manner
of performing the same, I declare that I claim the general arrangement of
parts forming a suspended weighing machine, as shewn and described, or any
modification thereof, whereby the weight of the merchandise or other material
and the tare may be ascertained at one operation.
In witness whereof, I, the said Henry Dean Denison, have hereunto
set my hand and seal, this Thirtieth day of July, in the year of our
Lord One thousand eight hundred and sixty.
HENRY DEAN DENISON. (L.S.)
