page_text: LETTERS PATENT to John Walker, Ironmonger, of Sheffield, in the
County of York, for the Invention of "IMPROVEMENTS IN THE CONSTRUC-
TION OF THE STANDARDS AND OTHER PARTS OF SCALES AND BEAMS FOR
WEIGHING PURPOSES, AND FOR THE MODE OF CONNECTING THE SAME."
Sealed the 25th October 1867, and dated the 11th May 1867.
PROVISIONAL SPECIFICATION left by the said John Walker at the
Office of the Commissioners of Patents, with his Petition, on the 11th
May 1867.
I, JOHN WALKER, Ironmonger, of Sheffield, in the County of York, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN THE
CONSTRUCTION OF THE STANDARDS AND OTHER PARTS OF SCALES AND BEAMS FOR
WEIGHING PURPOSES, AND FOR THE MODE OF CONNECTING THE SAME," to be as
follows:-
The principal feature of novelty in this Invention is the construction of the
standard which supports the beam. It consists of a strong heavy casting
with the base extending under the weight scale.
under the weight scale. It is cranked at or near
the top so as to place the centre of suspension of the beam some little distance
outside the standard, whereby ample room is provided for a large scale or
scoop to contain the goods to be weighed. At each end of the beam there is
a box or swan neck as 'may be required. The beam may be removed from

page_text: the standard when requisite, slots being cut in the top of the standard for that
purpose.
The hooks to attach the scales to the beam ends are made of flat
iron or steel, so as to prevent the scales or bails from twisting. The bail
holding the weight scale is provided with a cross bar under the look to
prevent the bail from ungearing when the goods scoop is lifted off.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Walker in the Great-Seal Patent Office on the
5th November 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
WALKER, Ironmonger, of Sheffield, in the County of York, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eleventh day of May, in the year, of our Lord One
thousand eight hundred and sixty-seven, in the thirtieth year of 'Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
John Walker, Her special licence that I, the said John Walker, my executors,
administrators, and assigns, or such others as I, the said John Walker, 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." IMPROVEMENTS IN THE CONSTRUCTION OF THE STANDARD
AND OTHER PARTS. OP SCALES AND BEAMS POR WEIGHING PURPOSES AND FOR THE
MODE OF CONNECTING THE SAME," upon the condition (amongst others) that I, the
said John Walker, 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 the said John Walker, do hereby declare the
nature of the said Invention, and in what manner-the same is to be performed,
to be particularly described and ascertained in and by the following statement
thereof, that is to say :-
One part of my Invention consists in constructing the standards of scales or
weighing machines. Instead of making the standards in a straight line, as is
usual, I make the top part of the said standards cranked so as to place the

page_text: centre or fulcrum of the beam some distance from the lower or remaining
portion of the standard, thereby providing ample space for a larger goods'
scale than could be applied to scales where the fulcrum of the beam rests on
the ordinary standard. By this improvement neither the standard nor the
beam need be so large as those used for the ordinary stand scales, a saving
of expense with portability and economy of space are thereby obtained.
Another part of my Invention consists in fitting the beam with box ends so
constructed that at any time required the parts may be immediately dis-
connected for any readjustment or repair of the centres or bushes.
Another part of my Invention consists in connecting the goods and weight
scales with the beam in the following manner :-The goods' or weight scales
have bales or cross handles which hang direct from the box ends of the beam
by flat hooks in such a manner as to prevent them turning or twisting when
in use. The bale or händle of the weight scale has a cross bar under the flat
hook which prevents it from disconnecting itself or getting out of gear while
the scale or scoop containing the goods is being used or removed. The
standard bottom may be screwed down so that the scale may project over the
edge of the counter or table, and the contents be discharged by tilting up the
scoop by means of the back handle of the said scoop.
Having explained the nature of my Invention, I will proceed to describe
with reference to the accompanying Drawing the manner in which the same
is to be performed.
Figure 1 represents in side elevation a scale or weighing machine con-
taining my several improvements; Figure 2 is an end elevation of the weight
scale of the same; Figure 3 represents in side elevation, and Figure 4 in end
elevation, a portion of the said weight scale and end of the beam drawn of a
larger size. The samé letters of reference are employed to indicate the same
parts in each Figure of the Drawing.
a is the base or bottom of the weighing machine, which may be screwed to
the counter or support, to which base or bottom is affixed the standard b; c is
the beam; d is the weight scale, and e is the scale or scoop for containing the
articles to be weighed. The upper part of the standard 6 is cranked, the said
cranked part being marked 6, the centre or fulcrum of the beam c being
carried by the said cranked part 2 as represented; by this construction the
centre or fulcrum c² of the beam c is placed some distance from the lower or
straight part 6 of the standard, and there is thereby provided ample room for
the scoop or scale e to hang freely without coming in contact with the
standard, and a larger scoop or scale may be used with the same sized
weighing machine than can be used when the fulcrum of the beam rests on

page_text: the top of the ordinary or straight standard as is usual: The beam c is fitted
with box ends marked respectively f, g; the said box ends are made in two
pieces, the concave sides of which are presented to each other and are fastened
together by the screws g², g', and f², fs. The shape and construction of the
box ends is best seen in the end elevation Figure 4; by this construction of the box
ends f, g, they may be readily disconnected for repairs or readjustment of the
centres or bushes. Each box end is provided with a flat hook marked h, i, to which
the scale d and scoop e are hung respectively. The tongue or upper end of the
flat hook is fitted between the lower ends of the two parts of the box end, and
the said flat hook is connected to the box end by the lower screw f'; g³, of
the respective box ends, the parts of the box end and hook are thereby
secured together. The scoop or scale e has a bale or cross handle k provided
with an angular loop, by which it is hung directly-to-the-box_end_g by the
flat book. The weight scale d has a bale or cross handle provided with a
similar angular loop, by which it is hung directly to the box end 'f by the
flat hook h, and the said loop 2 is also provided with a cross bar, which,
when the scale d is in its place is situated immediately under the flat hook h,
as represented in the Drawing. By hanging or connecting the scoop or
scale e and weight scale d to the beam c in the manner described and r repre-
sented, they are unable to turn or twist when in use, and by the employment
of the cross bar, in connection with the loop, the weight scale d is pre-
vented from being detached from its flat hook h, while the scale or scoop e
containing the weighed articles is being used or removed from its flat hook i.
The bottom or foot a of the standard 6 is, but little extended. on the scoop
side of the weighing machine, so that the said bottom or foot may be screwed
to the counter or table in such a manner as will enable the scale or scoop.e
to project over the edge of the said counter or table. By this means the
contents of the scoop or scale e are readily discharged from the said
tilting it by the ordinary handle at its back.

Having now described the nature of my Invention, and the manner in which
the same is to be performed, I wish it to be understood that I do not limit
myself to the precise details herein described and illustrated, as the same may
be varied without departing from the nature of my Invention; but I claim
as my Invention of improvements in the construction of the standards and
other parts of scales and beams for weighing purposes, and for the mode
of connecting the same,
Firstly, cranking the upper end-of-the-standard to receive the centre or
fulcrum of the beam for the purpose and substantially in the manner berein-
before described and illustrated in the accompanying Drawing.

page_text: Secondly, constructing the box ends of the beam substantially in the manner
described and illustrated in the accompanying Drawing.
Thirdly, the construction and combination of parts described and illustrated
in the accompanying Drawing for connecting the scales to the box ends of
the beam, whereby the turning or twisting and disengagement of the said
scales are prevented.
In witness whereof, I, the said John Walker, have hereunto set my
hand and seal, this First day of November, in the year of our Lord,
One thousand eight hundred and sixty-seven.
