page_text: LETTERS PATENT to Richard Longden Hattersley, of the Firm of.
George Hattersley & Sons, of Keighley, in the County of York,
Machine Makers, and Thomas Hebden, of the same Place,
Draughtsman, for the Invention of "IMPROVEMENTS IN MEANS OR
"
PROVISIONAL SPECIFICATION left by the said Richard Longden
Hattersley and Thomas Hebden at the Office of the Commissioners
of Patents, with their Petition, on the 28th March 1874.
WC, RICHARD LONGDEN HATTERSLEY, of the Firm of George
Hattersley & Sons, of Keighley, in the County of York, Machine
Makers, and THOMAS HEBDEN, of the same Place, Draughtsman, do
hereby declare the nature of the said Invention for IMPROVEMENTS
IN MEANS OR APPARATUS FOR. MOULDING AND CASTING METALS," to be as.
follows:-
This Invention relates to means or apparatus for the moulding of
tappits, cams, or eccentrics, or other articles of a similar nature with:

page_text: two or more wings or leaves cast together as used in looms for weaving
(and other machinery), whereby the said tappits, cams, or eccentrics, or
other articles when cast are in tiers or ranged along a boss or barrel, and
so timed as to suit the requirements of various designs or patterns in
weaving or other purposes. This is accomplished by the pattern or
model being fixed on to one end of a stud or short shaft which is
placed into a socket or bearing about the centre of a planed table on
which the model must rest. On the same stud or short shaft is fixed an
index plate, dividing wheel, or gauge, by which we are able to turn the
pattern or model on its axis into any required- position. The planed
table is also made to revolve on its axis in the same manner as in what
is known as "Clobson's moulding machines."
The method of working is as follows:-The model being in its proper
place an ordinary moulding box is placed over it on the planed table
and fixed with screws filled with sand, rammª up, and the table turned
over on its axis in the usual manner. The pattern and the moulded box
are thus suspended and whilst in that position a carrier or carriage is
placed on an under table, which is then raised by suitable apparatus into
conjunction with the moulded box to receive it when the screws or
clasps are loosed, and the carriage or carrier is lowered taking the
moulded box with the exception of the pattern or model in the sand,
leaving the said pattern or model attached to a table; a screen is then
placed over the moulded box to prevent any unnecessary sand. or
substances from injuring it. The table is then turned back to its former
position and the pattern moved on to its axis unto the next required
position by means of the index plate, dividing wheels, or gauges when it
is ready to receive another moulding box to be rammed up with sand;
the said box only being of the same depth as the model when rammed,
the table is again turned over and the box with the impression of pattern
therein deposited on the previous impression or box in the manner
previously described, and so, with other boxes (when moulded) in like
manner until the whole number of impressions, and and changes of
position of the model required to furnish the mould are completed. The
top part or last box being deeper as usual, when the mould is run
away on lines of rails, or may be carried by hand to a suitable place for
casting.

page_text: or face, for instance, we have two sides with a pattern on each suitably
placed, so that when each are moulded and delivered upon the other
on the carrier they will be in their proper positions. Also that we may.
have more than two sides or faces of the table or of polygonal form to:
any convenient number of sides with a pattern or model on each or any
of them properly arranged and fixed, and the table to turn over to any-
side so as to deposit the impressions in any required order upon the
carriage or carrier as before. By these methods such castings which are
difficult to make by the usual method of making them are easily and
quickly made by an ordinary workman.
SPECIFICATION in pursuance of the conditions of the Letters Patent;
filed by the said Richard Longden Hattersley and Thomas Hebden
in the Great Scal Patent Office on the 28th September 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, RICHARD.
LONGDEN HATTERSLEY, of the Firm of George Hattersley and Sons, of
Keighley, in the County of York, Machine Makers, and THOMAS
HEBDEN, of the same Place, Draughtsman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-eighth day of March, in the
year of our Lord One thousand eight hundred and seventy-four, in the
thirty-seventh year of Her reign, did, for Herself, Her licirs and suc-
cessors, give and grant unto us, the said Richard Longden Hattersley
and Thomas Hebden, Her special licence that we, the said Richard
Longden Hattersley and Thomas Hebden, our executors, administrators,
and assigns, or such others as we, the said Richard Longden Hattersley
and Thomas Hebden, our exccutors, administrators, and assigns, should
at any time agree with, and no others, from time to time and at all
times thereafter during the term therein expressed, should and lawfully,
might make, use, exercise, and vend, within the United Kingdom of
Great Britain and Ireland, the Channel Islands, and Isle of Man, an
Invention for "IMPROVEMENTS IN MEANS OR APPARATUS FOR MOULDING OR
CASTING METALS," upon the condition (amongst others) that we the
said Richard Longden Hattersley Thomas Hebden, our exccutors or
administrators, by an instrument in writing under our, or their, or
one of their hands and seals, should particularly describe and ascertain

page_text: the nature of the said Invention, and in what manner the same was
to be performed, and cause the same to be filed in the Great Scal
Patent Office within six calendar months next and immediately after
the date of the said Letters Patent.
NOW KNOW YE, that we, the said Richard Longden Hattersley and
Thomas Hebden, do hereby declare the nature of our said Invention,
and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement and
accompanying Sheets of Drawings, that is to say:
This Invention relates to means or apparatus for the mol ing of
tappits, cams, or excentrices, or other articles of a similar character with
two or more wings or leaves cast together as used in looms for weaving
(and other machinery), whereby the said tappits, cams, or eccentrices, or
other articles when cast are in tiers or ranged along a boss or barrel, and
so timed as to suit the requirements of various designs or pattern in
weaving or other purposes. This is accomplished by the pattern or
model being fixed on to one end of a stud or short shaft which is placed
into a socket or bearing about the centre of a planed table on which the
model must rest. On the same stud or short shaft is fixed an index plate,
dividing wheel, or guage, by which we are able to turn the pattern or
model on its axis into any required position. The planed table is also
made to revolve on its axis in the same manner as in what is known as
"Jobson's molding machines."
The model being in its proper place an ordinary moulding box is
placed over it on the planed table and fixed with screws filled with
sand rammed up, and the table turned over on its axis in the usual
manner. The pattern and the molded box are thus suspended, and
whilst in that position a carrier or carriage is placed on an under table,
which is then raised by suitable apparatus into conjunction with the
molded box to receive it when the screws or clasps are loosed, and the
carriage or carrier is lowered, taking the molded box with the impression
of the pattern or model in the sand, leaving the said pattern or model
attached to the table; a screen is then placed over the molded box to
prevent any unnecessary sand or substance from injuring it. The table
is then turned back to its former position and the pattern moved on its
axis into the next required position by means of the index plate,
dividing wheel, or guage, when it is ready to receive another moulding
box to be rammed up with sand; the said box only being of the same

page_text: depth as the model when rammed, the table again turned over and the
box with the impression of pattern therein deposited on the previous
impression or box in the manner previously described, and so with other
boxes (when molded) in like manner until the whole number of
impressions and changes of position required to finish the mold are
completed. The top part or last box being deeper as usual, when the
mold is run away on lines of rails, or may be carried by hand to a
suitable place for casting..
In some cases we dispense with an index plate or other dividing or
indicating means by having the molding table or bed of more than one
side or face, for instance, we have two sides with a pattern on cach.
suitably placed, so that when each are molded and delivered one upon
the other on the carrier they will be in their proper position. Also that
we have more than two sides or faces of the table or of polygonal form
to any convenient number of sides with a pattern or model on each or
any of them properly arranged and fixed, and the table to turn over to.
any side so as to deposit the impressions in any required order upon the
carrier or carriage as before. By these methods such castings which are
difficult to make by the usual method of making are easily and quickly.
made by an ordinary workman.
In order that this Invention may be clearly understood we herein.
give reference to two Sheets of Drawings of our improved apparatus,
wherein Fig. 1 is a side elevation; and Fig. 2, a front elevation of tho
same, cach partly in section; Fig. 3 is a plan view of the planed table
with pattern or model of tappit; and Fig. 4 is a plan of the index plate
or dividing, wheel.
The table A is supported on axes a in bearings of the framework so as
to be capable of turning over in the same, manner as in Jobson's
machine. The pattern or model B is fixed on the top end of a stud or
short shaft C carried by and capable of turning in a boss or bearing
formed at or about the centre of the table. The molding box D is
temporarily fastned to the table by screws c acting on the lugs d, tho:
said box being guided to its proper position thercon by pins 6 fixed to
the table and passing through holes in the lugs, the index plate e is also
fixed to the other end of the stud or shaft c under the table; it is divided
in circles into various numbers of sections with equal or unequal.
divisions of holes so as to obtain any required division of the circle, and

page_text: .
a spring lever with pin F is used to insert in any of the holes to hold the
pattern in proper position according to the sort or kind of tappits or
other castings required to be made.
The method of working is as follows:-The model or pattern B is first
placed in proper position, and an ordinary moulding box D placed over,
resting on the planed table A. The box is then filled with sand and
rammed up, after which the table is turned on its axis in the usual
manner, the model and box remaining suspended on the under side.
The carrier or carriage H mounted on wheels J resting on rails K on the
table L is then raised into conjunction with the molded box by means
of racks M, pinions N, and gearing O, P, Q. The molded box. D is
released from the planed table A and then rests upon the carriage H
which is lowered, and a screen placed over the molded box to prevent
any unnecessary sand or substance from injuring it. The table A is
then turned back to its former position, and the pattern moved on its
axis C into the next required position by means of the index plate e
when it is ready to receive another molding box, the same depth
as pattern which is again rammed up, turned over, and deposited
upon the preceeding molding box in the manner described above, and
so on until tho required number of molds or impressions have been
taken. The carriage H is kept in position upon the rails K by the
block K', and by the pins K' during the reception of the several
molded boxes; and when the series is finished the whole may be
conveyed to the position required for casting upon the rails L', which
are a continuation of the rails K.
By reference to the Drawings it will be seen that we make the first
box deeper than the remainder of the series, the last box also being of
the same depth as the first, or deeper than the intervening boxes.

page_text: It will be seen that any number of sides or faces may be employed
according to the number of sections required to complete the series of
moulds or impressions.
Having thus described the nature of the said Invention and shewn by
Drawings how the same is to be performed or carried into practical
operation, we would have it understood that we do not claim the whole
of the parts we have had occasion to shew and describe, nor do we
confine or restrict ourselves to the precise construction or arrangement
of apparatus, but what we do claim is,―
Firstly. The application to molding machines of an index plato or
dividing wheel in connection or combination with a moveable model,
operated in manner and for purposes shewn and described.
Secondly. The construction and use of a polygonal or many sided
table for molding upon as shewn and described.
Thirdly. The employment of rails and waggon in combination with
the table L, arranged suitably for receiving and retaining the molded
boxes in proper position, substantially as shown and described.
In witness whereof, we, the said Richard Longden Hattersley and
Thomas Hebden, have hereunto set our hands and scals, this
Twenty-fourth day of September, in the year of our Lord One
thousand eight hundred and seventy-four.
