Improvement in Bottom Works of Counter Weighing Machines,
J, WILLIAM JAMES HUBBARD 85 Drury Lane Strand London W.C. Scale &
Weighing Machine Maker do hereby declare the nature of my invention for
IMPROVEMENT IN COUNTER WEIGHING MACHINES to be as follows:-
The bottom connecting bar is made of forged steel the center bearing is made
of steel in each end of the bar is a slot which is placed on a stud form in the
bottom of upright which supports the scale the upright is made of wrought iron
faced with steel at bottom bearings at the back of upright is placed a moveable
stud and when in its proper position prevents the bottom bar from getting out of
place all bearings being made of steel & hardened give strength and durability
being simple in construction give ease in action by this invention we do away
with hooks loose shoes & screws which are now in use and obtain a longer up and
down action which is so essential to trades using this class of weighing machine.
Dated this 7th day of January 1886.

I, WILLIAM JAMES HUBBARD of 85 Drury Lane Strand London in County
of Middlesex Scale Maker do hereby declare the nature of my invention for
IMPROVEMENT IN BOTTOM WORKS OF COUNTER WEIGHING MACHINES and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:—
The bottom bar is made of forged steel the center bearings is made of steel in
each end of the bar is a slot which is placed over a stud formed in bottom of
upright which supports the scale the upright is made in one piece of wrought iron
steel faced at bottom bearings at the back of upright is a moveable stud and
when in its right position prevent the bottom bar from getting out of its place.
By this invention I supersede the present system of hooks which are kept in
their place by wire keys and are liable to get out of order Having no keys at
bottom I obtain more drop or up and down action I also supercede the system
of loose shoes at the bottom of upright which are dependant on a screw which soon
becomes defective. By my Invention every part is made solid and durable simple
in construction giving ease in action.
The iron stand D which supports the whole is of new design being longer and
wider the roof being flat to accomadate the bottom works so that when the
uprights A which supports the scales are put down the pipe of the stand D the
bottom bar C is placed in the center bearing B the ends are placed over the studs
formed in the bottom of upright A the stud at the back of upright A when turned
to its proper position prevents the bottom bar C from getting out of its place all
the works being level they can be so raised as to regulate the drop or up & down
action to suit any trade using this class of scale.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is
1. The several parts, being made solid and in one piece gives strength and
durabillity.
2. Being simple in construction and all the bearings being brought up to a fine
edge reduces the friction to a minimum giving great ease in action.
3. That having disposed of all impediments at the bottom of uprights we get
better up & down action and are not liable to get out of order.
Dated this 6th day of September 1886.
