Middlesex 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 :-
This invention consists of a new and improved ornemental stand and action to
weighing machines at each end of the stand is a tube between the frame and the top
of the tube is a cross bar for centre bearings for receiving centre pins of lever or
properley called beam of machine which can be straight or cranked as to fancy with
six knife edges with 2 bearings in front cross and 2 in back cross to receive scale pan
and weight pan through the front cross and weight Pan or Cross I place Improved
legs or uprights but commonley called legs with flat ends and long narrow eyes with
knife edges at the bottom and a scutcheon above the eyes coming through the tubes at
each end of the stand the tubes acting as stops thus saving the legs from Injury or the
machine from sticking by matter falling on the frame of the stand as is the case in
with orderany weighing machine scales whilst weighing. In the centre of the bottom
of the stand is a fork to attach a new Improved connetion rod to connet legs with
6 notches and 12 knife edges 2 notches at each end and 2 in the centre or could be
made with 2 knife edges in the centre but I prefer 4 knife edges by placing the rod
sideways in the fork in the centre of the stand and the eyes of the legs and turning it
flat in the notches of the connection rod setting the machine on all knife edges working
against flat surfaces.
Turning the scutcheons down prevents the connection rod being displaced this
action I can use in weighing machines with stops on the legs and no tubes on the
stand also at top action in other weighing machines by using my invention it thus
dispences with the use of wires, rings, screws, and other appliances for keeping the
machine together, leaves every part of the action free with less friction and less liable
to get out of order or repair as orderany Weighing Machines.
In order that my invention may be the better understood I now proceed to describe
the same in respect of the sheet of drawings hereunto annexed in which
Figure 1 represents a sectional elevation of my scales complete.

page_text: Figure 2 represents a detail of the notched bar.
Figure 3 represents the pivotted attachment of the legs or uprights to the
notched bar.
Figure 4 re resents a detail of the frame with projections for receiving the centre
pins of the beam.
Like letters refer to like parts throughout the figures.
A A are the tubes projecting above the frame, B is the notched bar, shown in detail
in figure 2; C shows the projecting piece upon the frame to receive the centre pins
of the beam, which are thus held free from dust or likllihood of any matter falling on
the frame. For this purpose also are designed the tubes A aforesaid. Referring to
the notched bar B it will be seen that by the particular method of notching the same
attachment is made without the use of screws or wires. The bar is slid through
slots D, figure 3, at the foot of the legs. It is then turned flat, as shown in figure 1,
the notches engaging with the sides of the slot, and it is then locked in place by means
of the pivotted scutcheon E, shown open and with the bar when being put in place in
figare 3ª, and with the bar placed flat and locked in figure 3º.
Having now particularly described and ascertained the nature of my said invention
and what manner the same is to be performed I declare that what I claim is:-
First. The manufacture and use of the improved stand and action to weighing
machines.
Second. The notched connection rod with knife edges also the legs of machine with
long narrow eyes scutcheons above the same and knife edges at bottom of the flat
surfaces of legs.
Third. The use of my action in Weighing machines as a top action or bottom action
with stops on legs or without tubes on stand.
Dated this Third day of May 1886.
