An Improved Construction of Weigh-bridge Frames.
I, HENRY POOLEY, of Albion Foundry, Manchester Street, Liverpool, in the
County of Lancaster, Weighing Machine Maker, do hereby declare the nature of
this invention to be as follows:-
This invention has reference to the construction of the frames of weigh-bridges,
which are made up of plates or beams at the ends and sides of the machine, and
which are set usually below the level of the surface or ground, and contain within
them the levers and parts connected therewith of the weighing mechanism. The
invention comprises or consists of special constructions by which the end and side
plates can be formed or cast in such a condition as to enable them to be fitted and
fastened together with little or no fitting or tooling of the parts thereof, and
which come in contact with each other and form the joint, and without special
fastenings.
According to this invention, the levers of the machine are adapted to be secured
or supported and attached to the end plates of said frame, and these end plates
are provided at each end with corner posts or standards, whilst the side plates are
also provided with similar corner posts or plates. On the end face of each of the
corner posts of the side plates, is provided a projecting ledge, or a number of
projecting parts; whilst on the inner face of the corner posts of the end plates is
provided a corresponding channel, or recesses, which are formed by metal parts at
each side, or round them; whilst at the top-or an equivalent part-thereof is a
projecting part, the lower edge of which is adapted to rest on the upper end of the
projection or projecting parts of the end posts of the side plates.
In connection with these provisions, suitable fitting strips or equivalent parts are
provided, which form the bearing faces of the posts of the side and end plates,
respectively, when placed together. These faces or provisions are so made as to be
easily chipped or tooled, if or when desired.
The plates are connected together by bolts passing through holes in said posts
and without the frame, such holes being preferably cored out.

COMPLETE SPECIFICATION.
An Improved Construction of Weigh-bridge Frames.
I, HENRY POOLEY, of Albion Foundry, Manchester Street, Liverpool, in the
County of Lancaster, Weighing Machine Maker, do hereby declare the nature of
this invention and in what manner the same is to be performed, to be particularly
O described and ascertained in and by the following statement :—
This invention has reference to the construction of the frames of weigh-bridges,

page_text: which are made up of plates or beams at the ends and sides of the machines, and
which are set usually below the level of the surface or ground, and contain within
them the levers and parts connected therewith of the weighing mechanism. The
invention comprises or consists of special constructions by which the end and side
plates can be formed or cast in such a condition as to enable them to be fitted and
fastened together with little or no fitting or tooling of the parts thereof,. and
which come in contact with each other and form the joint, and without special
fastenings.
According to this invention, the levers of the machine are adapted to be secured
or supported and attached to the end plates of said frame, and these end plates are
provided at each end with corner posts or standards, whilst the side plates are also
provided with similar corner posts or plates. On the end face of each of the
corner posts of the side plates, is provided a projecting ledge, or a number of
projecting parts; whilst on the inner face of the corner posts of the end plates is
provided a corresponding channel, or recesses, which are formed by metal parts at
each side, or round them; whilst at the top-or an equivalent part-thereof is a
projecting part, the lower edge of which is adapted to rest on the upper end of the
projection or projecting parts of the end posts of the side plates.
In connection with these provisions, suitable fitting strips or equivalent parts are
provided, which form the bearing faces of the posts of the side and end plates,
respectively, when placed together. These faces or provisions are so made as to
be easily chipped or tooled, if or when desired.
The plates are connected together by bolts passing through holes in said posts
and without the frame, such holes being preferably cored out.
In the drawings illustrating this invention its application is shewn in connection
with weigh-bridge frames of different sizes, the different constructions shewn in the
respective cases being more especially suited to their special size.
The group of views under Figure 1 represent, on the left hand side, a front end
and side view of the side frame, and at the left, an end view and an inside side
view of the end frame; and the groups of views shewn in Figures 2, 3, and 4,
represent a modified construction of the side and end frames with the same
arrangement as to the views, precisely.
Referring in the first instance to Figure 1, e denotes the end frame with an end
post e, and the side frame with an end posts (these letters represent the
respective frames and posts throughout). To obtain the required relative adjust-
ment and placing of the trames in the horizontal direction, on the posts e of the
end frame e is provided a projecting part a, the lower or under side of which fits
on the top of a projecting part b on the post s' of the side frames, the face of the
part a abutting against the face of the frame post s'. The adjustment and holding
of the frames to and in relation to one another in other respects, that is for lateral
adjustment and retention, is effected partly by the projection b, which lies in
between projecting strips or bars d on the post e of the frame e, and partly by bolts
which pass through holes in the end posts s' and e' of the frames, such holes
being formed in casting the frames by placing cores in prints in the moulds at the
required points, one at least of these cores being square, preferably, and one round,
and the bolts being correspondingly made with a square part near the head. The
correct position of the frames in relation to each other is thus assured and
maintained. The middle and lower parts of the end posts of the frames are
provided with projecting bars or strips c on the frame posts s', and strips d on the
end posts e' which abut against each other.
By providing the frames with posts and fittings, as described above and hereafter,
truly cast, no tooling of the joints is necessary, and when they are drawn up tight
by bolts preferably square at one part to fit in the square holes-the frames are
truly and rigidly held in position.
The supports and other fittings for the weighing beams or levers of the, weighing

page_text: inachine, which are disposed within the frames, will be formed on or secured to the
frames in the usual way.
In Figure 2, the fitting a of the end frame e is made with inclined sides, riz. in
the form of a truncated wedge, and, preferably, slightly dovetail in shape vertically,
when viewed in front; and it is adapted to fit within the recess of a Ụ shaped
projecting part b on the side frame post s', which it fills. Intermediate projections c
and d are formed on the end frame and side frame posts, the edges of which abut,
whilst at the lower part, a projection similar to a, denoted d¹, is formed on one
frame post, and similar projections d² are formed on the other frame post, between
which the projection d' is adapted to lie, and make joint therewith. Thus the
horizontal position is obtained by the lower side of the projection a lying on or
touching the bottom of the projecting part b, and the lateral positions are secured
at the top and bottom by the coincidence of the projections a with b, and d' with
the spaces within d²; while the whole frames are held together by bolts passing
through the holes fas in the manner above specified.
In Figure 3 the end frames e are carried round in the form of an elbow or angle,
and the posts e thereof are disposed at the end of this angle. In the posts, in
this case, the projecting part is formed, whilst on the post e the projecting
part b, bars or strips d, and the lower parts d' are joined together so forming a hollow
space within them. The projections a and d' having inclined sides, and the inside
surfaces of the projecting parts b and being correspondingly formed, they
coincide, and make the required joint, whilst their faces and those of the bars d
abut up against the face of the post s¹. The horizontal position and adjustment is
effected by the top surface of the projecting part b-which is carried over the top
of the space within it, fitting on the upper edge of the projection a.
Referring to Figure 4, the elbow construction of the end frame e is the same as
those described with reference to Figure 3. The posts in this case, however, are
differently constructed, namely, the projection a is at the centre of the post e' of
the end frame, having inclined sides, whilst the part b in which it fits is made by
forming a recess in the post s'. The projection a having an inclined side, and the
recess being made to correspond in form to the projection a, they coincide, and
adjustment of the two frames in relation to each other horizontally and laterally,
is afforded. The adjustment endwise between the two frames at the top and bottom
is afforded by providing bars or strips d & c on the posts e¹ and s¹, the edges of
which abut up against each other, while the frames are drawn up together and ·
held by bolts passed through upper and lower bolt holes f.
With the parts or fittings above described coinciding and held together as
described, true adjustment of the frunies in relation to each other is afforded, and
their movement out of adjustment is obviously rendered impossible when drawn up
together by their fastening bolts.
It will be obvious, that as regards the particular frames, in connection with
which the parts or fittings hereiu specified are used, the converse of those shewn
and particularly specified may be used; and that the exact configuration or form
thereof will not be restricted to those specifically shewn. Then as regards the
different arrangements shewn in the different figures for the different sizes of machines,
it is to be stated that while I at present prefer these forms, they may be inter-
changed in the different sizes of machine, where circumstances or conditions may
be deemed to render it expedient so to do.
Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed, I declare that what I
claim is :-
The herein described improved construction of weigh bridge frames, namely,
cast frames consisting of side and end members joined together at or near their
ends, said ends or junction parts having posts or plates with fittings cast thereon
in casting the frames, the fittings on the one post or plate being adapted to fit in

page_text: or coincide with those of the other post, the said parts being held up together by
bolts as herein set forth with reference to and shewn in the drawings hereto
annexed.
