Improvements in the Construction of the End-frames of Washing
and like Machines, and in Means for use in the Manufacture of
same.
We WILLIAM HENRY MURTON and WILLIAM SAGAR VARLEY of The
Anchor Iron Works, Keighley in the County of York, Machine Makers, do
hereby declare the nature of this invention to be as follows, that is to say :-
It relates to improvements in the construction of the end-frames of washing
and like machines and in means for use in the manufacture of same, these
said improvements having more especial reference to those end-frames that are
formed or constructed of tubular pieces of metal, and our invention consists of
forming and constructing certain of the solid parts for attachment to the tubular
parts in such a manner that their said attachment is more rigid and secure than it
has been heretofore, while in the manufacture of these said end-frames we so con-
struct or form the moulding boxes, used for maintaining the tubular pieces in
position while the molten metal is being run or applied for holding or binding them
rigidly together, that the moulding sand is only required at the places where the
molten metal has to be placed, those spaces between being entirely empty.
The object of our invention is attained by forming the solid screwed bolts which
are for attachment to the extremities of the bifurcations on the end-frame, so that
that portion of them which is for insertion into the hollow ends of the tubular
parts, should be less in diameter at about its middle part by which means when
inserted into their positions in the tubes on these tubes being heated and hammered
or otherwise caused to tightly fit over them they are securely and rigidly held by
and attached to these said tubes.
When the pieces of tubing are bent or properly shaped, to occupy their
respective relative positions for forming the end-frames, we take them and place
them in moulding boxes that are formed, by having suitably shaped cross bars for
holding them in their positions irrespective of the moulding sand, and these
boxes are also formed so as to hold the moulding sand at such places as
are alone necessary for forming the mould into which the binding metal is to be
run by which means the ramming of the sand at any other than those said places
is entirely avoided with the consequent saving in time and labour.

COMPLETE SPECIFICATION.
Improvements in the Construction of the End-frames of Washing
and like Machines, and in Means for use in the Manufacture of
same.
We, WILLIAM HENRY MURTON and WILLIAM SAGAR VARLEY of The
Anchor Iron Works, Keighley in the County of York, Machine Makers, 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, that is to say :-
It relates to improvements in the construction of the end-frames of washing and

page_text: like machines and in means for use in the manufacture of same, these said
improvements having more especial reference to those end-frames that are formed
or constructed of tubular pieces of metal, and our invention consists of forming
and constructing certain of the solid parts for attachment to the tubular parts in
such a manner that their said attachment is more rigid and secure than it has been
heretofore, while in the manufacture of these end-frames we so construct or form
the moulding boxes, used for maintaining the tubular pieces in position while the
molten metal is being run or applied for holding or binding them rigidly together,
that the moulding sand is only required at the places where the molten metal has
to be placed, the other intervening spaces being entirely empty.
In the accompanying sheet of drawings;
Fig. 1 is illustrative of the class of end frame to which our invention applies.
Fig. 2 is a sectional view, enlarged scale, of the extremity of one of the
bifurcations on the end frame.
Fig. 3 is top view of a moulding box reduced scale, showing the arrangement of
the tubular pieces of metal and the places or moulds into which the molten metal
is poured.
Fig. 4 is a perspective view showing the formation of the moulding box.
Fig. 5 is illustrative of the same method of construction in moulding boxes to be
applied in the making of rails for the framework of machines.
We attain the object of our invention by forming the solid screwed bolts a which
are for attachment to the extremities of the bifurcations bb' on the end-frame c,
so that the part a¹, which is for insertion into the hollow ends of the tubular
parts bb, is less in diameter at about its middle part a² by which means when
inserted into their positions in the tubes b b on these tubes being heated and
hammered or otherwise caused to fit tightly over them, as shown by Fig. 2, they
are securely and rigidly held by and attached to these said tubes b b².
As to the manufacture of the end-frames or framework, after bending or
shaping the several pieces of tubing to prepare them for occupying their respective
relative positions so that when they are attached to each other the parts desired
are produced, we take these tubes 6, 61, d and e, and place them in moulding boxes
that have cross bars g into which are made the notches the same being arranged
for holding these pieces of tubing in position irrespective of any moulding sand;
and the positions of these bars 9 are further regulated so that it is not necessary
to place any moulding sand in any of the spaces k, the spaces m, in which the
molten metal for binding the parts as at n, being the only places in which the
moulding sand is required. This method of forming moulding boxes of with cross-
bars g having notches h made in them, may be in like manner followed in the
manufacture of the other parts of framework as the rail p p¹, Fig. 5, in which case
by having the series of additional notches ¹ formed in the bars g' it is only
necessary to place the parts ppl a greater or less distance apart from each other
to produce a longer or shorter rail, the cast part n' being longer or shorter to effect this
variation. And by following such a method and employing such moulding boxes
the ramming of the sand at any other places than those indicated is entirely
avoided with the consequent saving in time and labour.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1. The method of attaching screwed or bolt parts to the bifurcations of end
frames made of tubular pieces of metal substantially as specified.
2. Screwed or bolt parts formed with their ends for attachment of smaller
diameter in or about the middle of said part for attachment so that the tube
fitting tightly over same prevents its removal substantially as set forth.
3. The formation of moulding boxes with cross bars to divide same into spaces
that are to be filled with sand, said cross bars being also formed to hold the pieces
