Improvements in the Apparatus or Implements Employed in
Foundries in Carrying or Lifting Patterns or Removing Patterns
from the Sand or other Material Employed.
We JOHN BUTLER of 16 Cottrill Street Salford in the County of Lancaster Moulder
and JAMES EVANS of Albion Mills, Trumpet Street Gaythorn, Manchester in the
County of Lancaster Moulders' Engineer do hereby declare the nature of this
invention to be as follows :-
Our invention relates to the apparatus or implements employed in foundries in
carrying or lifting patterns or removing patterns from the sand or other material
employed. The apparatus or implements hitherto in use for the purpose above referred
to each consist in a handle and shank upon or to which a screwed portion is formed or
secured by welding.
The screwed portion above mentioned rapidly becomes worn and unfit for use and
requires frequent renewal and if used in an injured or worn state it fails to securely
hold the pattern and often causes injury to the pattern and mould and the renewal or
repair of the said screwed portion necessitates the expenditure of time and labour and
entails considerable cost.
Our invention consists firstly in arrangements by which the apparatus or implements
above mentioned are rendered more capable of being quickly and cheaply repaired
than they have hitherto been.
In accomplishing the object of our invention we employ a screwed portion formed
separate from the handle or shank in conjunction with which it is used and secure the
said screwed portion and the said handle or shank together by means of parts capable
of being screwed or otherwise secured together so as to secure the handle or shank
and the screwed portion together.. The said screwed portion may be of any suitable
form or size and may be provided with a part suitable for being acted upon by a part
formed upon the handle or shank which when the parts are secured together ensures
that the handle or shank and the screwed portion shall move together.

page_text: In one application of our invention we are enabled to employ the screws ordinarily
used in wood work. In this application of our invention we form the shank above
referred to with a projecting part which passes into the nick formed in the head of
each of such screws aforesaid so that when the screw is secured upon the handle or
shank as above described the projecting part above mentioned ensures that the screws
shall turn with the handle or shank.
The above mentioned parts which are capable of being screwed or secured together
are made of any suitable form and one of them may be attached to or secured upon
the handle or shank in any suitable manner such as for instance by means of an
enlarged part formed upon the said handle or shank and the other of the said parts
may be attached to or secured or formed upon the screwed portion above mentioned
in any suitable manner.
By employing parts of suitable sizes for securing the screwed portions above
mentioned to the handle or shank above mentioned screws of different sizes may be
employed in conjunction with one handle or shank.
Our invention further consists in so forming that of the parts capable of being
screwed together, which is secured upon or attached to the handle or shank that the
apparatus or implement may be increased or decreased in length when required. In
accomplishing this part of our invention we form the said part of any suitable length
and we secure or attach the handle or shank therein or thereon by means of set-screws
or thumb-screws or in any other suitable manner, thereby enabling the said handle or
shank to be placed further in or to be withdrawn from, the said part. By means of
the above described arrangement we form an apparatus or implement particularly
applicable for use in cases where the moulding box and pattern require to be turned
over during the process of moulding.
In some cases to enable the above mentioned handle or shank and screwed portion
to be readily removed from the pattern and sand or other material employed we form
the part which secures the screwed portion to the handle or shank as a tube such tube
aforesaid enabling the handle or shank and screwed portion to be withdrawn from
the pattern and sand or other material employed without breaking down the sand or
other material employed.

page_text: We, JOHN BUTLER, of 16 Cottrill street, Salford, Moulder, and JAMES EVANS of Albion
Mills, Trumpet street, Gaythorn, Moulder's Engineer, both in the County of Lancaster,
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:
It consists in certain improvements in the apparatus heretofore employed in carrying
or lifting patterns or removing them from the sand, or other moulding material.
This apparatus has hitherto consisted of a handle and shank to which a screw suitable
to insert in the pattern is permanently attached by welding. This screwed portion
rapidly becomes inefficient owing to the thread becoming worn away, and therefore
needs frequent repairs and renewal. The screwed portion moreover being permanently
attached to the handle, necessitates the keeping of a large number of handles with
screws suitable for a large variety of patterns.
One object of our invention is to provide a suitable arrangement whereby the
screwed portion can be readily changed so as to suit different patterns, and replaced
when worn.
To accomplish this we employ a suitably formed socket separate from
the handle into which suitable screws or screwed ends can be fitted, and which
is furnished with a suitable screwthread or other suitable means by means of which
it can be attached to suitable corresponding parts attached to the shank. The said
screws or screwed ends may be of any suitable size or shape, and are suitably formed
or provided with a part, by means of which when screwed into the shank another
part attached to the shank assures their movement with the shank.
When our invention is applied to screws such as are ordinarily used in wood work,
we form the shank with a projection, which when the socket is screwed into the corre
sponding parts attached to the shank, enters into the neck formed in the head of the
wood screw, aforesaid and insures its turning with the shank. By employing a number
of sockets as before mentioned with suitable apertures to take different sizes of screws
or screw ends, screws of different sizes may be employed in conjunction with one
handle and shank.
When other ends of a curved form are used, such as cannot be passed through the
socket above described we use a split socket, which we tighten by means of an outside

page_text: thread and nut or similar means, the outside nut being so applied as to press down a
part into or over a suitable part formed in or upon the other ends, so as to secur
their rotation with the handle. Or we may employ a split socket screwed into the
shank as already described.
Another object of our invention is to form the beforementioned handle or shank in
such a manner that it can be withdrawn from the sand without breaking it down. To
accomplish this we form the shank of a tube of such a diameter that it exceeds the
diameter of the socket employed to hold the screw and the screwed part by which it is
attached. This contrivance is specially applicable in cases where the moulding box or
pattern has to be turned over during the process of moulding. Another object of our
invention is to form the shank in such a manner that it can be readily shortened and
lengthened this we can do in many ways by means of suitable slides and screws.
One method is as follows:-We make use of two tubes an outer tube and an inner
tube, the outer tube sliding upon the inner tube in the manner of a telescope tube.
To the lower end of the inner tube is fixed the apparatus already described for
attaching the screwed ends.
Into its upper end is fitted a revolving disc which closes the tube, and is provided
with a suitable catch, by means of which, its revolution can be checked. Up the
centre of the tube is fitted a long screw with a very swift thread which passes
through the centre of the revolving disc beforementioned and works in a suitable
corresponding thread cut in it. The upper end of the screw is furnished with a handle
of suitable form, and the upper end of the outer tube is closed by a suitable screw cap
which can be readily screwed and unscrewed.
In use, the screw cap at the top of the outer tube is unscrewed, and the handle
drawn out to the required length, the centre screw revolves the disc while being drawn
out, which when secured by its catch fixes the handle at the proper length. The outer
tube is then drawn out to the right length and secured by its screw cap. To shorten,
the operation is reversed. In order that the foregoing may be better understood, we
send herewith a sheet of Drawings in which :-
Fig. 1 is an elevation of the apparatus showing the arrangement for attaching
and detaching the screws, a being the handle 6 the shank and c screwed portion
attached to the shank in which, the screwed socket d is inserted, dotted lines c¹ indicate
