COMPLETE SPECIFICATION.
Improvements in Weight Indicators.
We, EDWARD CHARLES THEEDAM, of High Street, Dudley, in the County of
Worcester, Manufacturer, and BENJAMIN RICHARD ISAAC, of 45, South John
Street, Liverpool, in the County of Lancaster, Metal Merchant, 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 relates to the improvements in the construction and arrangement of
weight indicators such as are usually applied to coal or other carts or waggons, and
which may also be applied to railway rolling stock, its primary use being intended
for the former, to indicate the tare weight of the cart, or in some cases of the
horse as well as the cart, &c., inasmuch as from time to time such weight is
changeable.
The object of this my invention is to provide a frame, (to receive removable and
changeable letters or figure plates,) having a perforated cover plate by which such
figure or letter plates are held in the said frame, so that such loose plates may be
easily changed when necessary, by first withdrawing the said cover plate after the
manner hereinafter explained.
In order to more fully explain this my said invention I have appended hereunto
an illustrative sheet of drawings, upon which are figures and letters of reference,
similar letters referring throughout the several views to the same thing or part.
Fig. 1, is a view in elevation of this my invention showing the frame open ready
to receive the loose plates.
Fig. 2, is a similar view, showing the indicator closed, and with the plates
inserted.
Fig. 3, is a sectional view of Fig. 2, on line A-A.
Fig. 4, is a detached part view of the one end of the indicator, as arranged for
locking the cover plate in position.
Fig. 5, is an end sectional elevation of Fig. 4, on line B-B.
Fig. 6, is a detached part view of the one end of the indicator, showing a modifi-
cation in the method of fastening.
Fig. 7, is a sectional part plan view of Fig. 6, on line C-C.
Fig. 8, is a view in elevation of this my invention showing a modified form of
cover plate.
Fig. 9, is a sectional end view on line D-D, in Fig. 8.
Fig. 10, is a sectional part plan view on line E-E, Fig. 8.
Fig. 11, is a detached detailed front view, and Fig. 12 an end view of the figure
plates.
F, is a frame, preferably of cast iron but which may be of stamped metal, having
at its one end a fixed pin or pivot G, upon which swings the cover H. At the
other end of this frame F, is the fixed headed stud I, on to which passes the slot J,
in the cover H.
The centre of this frame is left open or recessed to receive the figure plates K,
(see Figs. 11 & 12).
Suitable screwdown holes L, L, L, L, are provided by which the said frame may
be secured to the carts & c.
In the cover plate H, are provided the two apertures M and N, through which
appear respectively (as illustrated) the number of cwt. and qrs. of the tare weight.
If desired however three or more of these apertures may be used to indicate other
quantities or characters of weight. When this cover is turned down as seen in
Fig. 2, the loose figure plates are effectually prevented from falling therefrom.
In some cases instead of having the headed stud I, ou to which the end of the
rei 021

page_text: cover passes, may modify it as seen in Figs. 6 & 7, by providing upon the
frame the grooved projection O, into which, the end of the cover may pass.
Again. In some cases I further provide a locking device as shown in Figs. 4 & 5,
in which P, is a staple fixed in the frame F, and Q, Q, are lumps formed upon each
side of the slot J', and at its lower part, so that when passed into their closed
position, the bar R, of a padlock may be passed through the staple, when the cover
will be effectually locked, inasmuch as the lumps Q, Q, cannot be withdrawn until
the bar R, has been removed.
In Figs. 8 & 9, I have shown the cover H', as being slid in grooves in front of
the tablets, and in which a similar locking device to that already described is
adopted, P, being the staple, Q, Q', the locking lumps, and R', the padlock bar.
The figure plates (see Figs. 11 & 12,) are of metal having on their faces the
numbers, stamped, enamelled or painted as may be most desirable.
Having now particularly described and ascertained the nature of this my
invention, and in what manner the same is to be performed, I declare that what
1 claim is :-
1. In weight indicators for carts, waggons, or other similar purposes, the com-
bination with a fixed frame having therein removable and changeable figures, of a
moveable cover plate thereto, by which such figures are held in position, and having
apertures therein through which the figures appear, substantially as described and
illustrated.
2. The combination with the frame, having moveable figures, and the cover plate,
of the locking device substantially as set forth and shown.
The general combination and arrangement of any or several of the parts herein-
described and shown in which the moveable cover plate is used in combination with
the frame, to constitute my improved weight indicator.
Dated this 8th day of December 1891.
