Year: 1867

page_text: LETTERS PATENT to Joseph Smith, of Keighley, in the County of York,
Machine Maker, for the Invention of "IMPROVEMENTS IN MACHINERY OR
APPARATUS FOR MOULDING METAL."
Sealed the 4th April 1868, and dated the 7th October 1867.
PROVISIONAL SPECIFICATION left by the said Joseph Smith at the Office
of the Commissioners of Patents, with his Petition, on the 7th October
1867.
I, JOSEPH SMITH, of Keighley, in the County of York, Machine Maker,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
MACHINERY OR APPARATUS FOR MOULDING METAL," to be as follows:-
One part of this Invention consists in combining and arranging mechanical
means for lifting the top moulding box and lowering the bottom moulding
box, either simultaneously or separately. To produce this effect I employ
two, three, or more eccentrics fixed on a rotary shaft, and place them in two
opposite positions, and connect them by rods or bars to the top and bottom
boxes respectively, by the action of which motion will be given to the boxes
in opposite directions to each other; or I may employ right and left handed
screws, or racks and pinions, or other mechanical equivalents, and operate
them so as to produce this duplex motion; or I may use one eccentric or its
equivalent only, and arrange for it to act upon each box separately by means
of portable hooks or arms. I also employ a carriage with bearings in which
the moulding plate or the pattern plate is mounted on axes, so as to allow the
plate to turn over when required to do so; or the plate may be supported
on flat bearings when not required to be turned over. This carriage is
capable of sliding or running on rails of suitable framing for removal of the

page_text: said plate; by this means I am enabled to place both boxes and plate in
position together so as to ram up one box, then turn over and ram up the
other box, then separate both boxes from the plate simultaneously, and slide
or run the carriage away, removing the said plate from betwixt the boxes,
which are then closed for casting or receiving the molten metal.
Another part consists in having the pattern plate attached to arms mounted
on or projecting from one side of an axis or shaft so as to be capable of
turning over, a balance weight being applied to the opposite side, whereby I
am enabled to place and fix one box upon one side of the plate, ram up, and
then turn it over or transfer the box to the opposite side of the axis, and thus
change their relative positions, the box being turned underneath the plate;
I then place and fix tho other box on the top of the plate, ram up, and then
detach the lower box from the plate; I then return the shaft and plate,
transferring the last rammed box to the opposite side of the axis, where it is
also detached and the pattern plate removed from it; the boxes are then
placed together by band in the usual manner.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Joseph Smith in the Great Seal Patent Office on the
7th April 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPH
SMITH, of Keighley, in the County of York, Machine Maker, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Seventh day of October, in the year of our Lord
One thousand eight hundred and sixty-seven, in the thirty-first year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Joseph Smith, Her special licence that I, the said Joseph Smith,
my executors, administrators, and assigns, or such others as I, the said Joseph
Smith, my executors, 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
MACHINERY OR APPARATUS FOR MOULDING METAL," upon the condition (amongst
others) that I, the said Joseph Smith, my executors or administrators, by an
instrument in writing under my, or their, or one of their hands and seals,
should particularly describe and ascertain the nature of the said Invention,
and in what manner the same was to be performed, and cause the same to

page_text: be filed in the Great Seal Patent Office within six calendar months next
and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Joseph Smith, do hereby declare the
nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement thereof and accompanying Sheet of Drawings (that is to say) :-
One part of this Invention consists in combining and arranging mechanical
means for lifting the top moulding box and lowering the bottom moulding
box, either simultaneously or separately. To produce this effect I employ
two, three, or more eccentrics fixed on a rotary shaft, and place them in two
opposite positions, and connect them by rods or bars to the top and bottom
boxes respectively, by the action of which motion will be given to the boxes
in opposite directions to each other; or I may employ right and left handed
screws, or racks and pinions, or other mechanical equivalents, and operate
then so as to produce this duplex motion; or I may use one eccentric or
its equivalent only, and arrange for it to act upon each box separately by
means of portable hooks or arms. I also employ a carriage with bearings in
which the moulding plate or the pattern plate is mounted on axis so as to
allow the plate to turn over when required to do so; or the plate may be
supported on flat bearings when not required to be turned over. This
carriage is capable of sliding or running on rails of suitable framing for
removal of the said plate. By this means I am enabled to place both boxes
and plate in position together so as to ram up one box, then turn them over
and ram up the other box, then separate both boxes from the plate.simul-
taneously and slide or run the carriage away, removing the said plate from
betwixt the boxes, which are then closed for casting or for recieving the
moulten metal.
Another part of this Invention consists in having the pattern plate attached
to arms mounted on or projecting from one side of an axis or shaft, so as to
be capable of turning over, a balance weight being attached to the opposite
side, whereby I am enabled to place and fix one box upon one side of the
plate, ram it up, and then turn it over or transfer the box to the opposite
side of the axis, and thus change their relative positions, the box being
turned underneath the plate upon a suitable bed or table; I then place and
fix the other box on the top or on the other side of the plate, ram it up,
and detach the lower box from the plate. The shaft and plate are then
turned back, transferring the last rammed box to the opposite side of the axis
on to a bed, where it is also detached and the pattern plate removed from it;
the boxes are then placed together by hand in the usual manner.

page_text: DESCRIPTION OF THE DRAWINGS.
Fig. 1 represents a side elevation, and Fig. 2 an end elevation of a
machine constructed according to the first part of the said Invention.
A is the framework or a pillar upon which the working parts are mouuted;
B, the moulding table, having a stem B' capable of sliding up and down in a
hole formed in the pillar; C and D are two halves or parts of a pair of
moulding boxes; and E is the pattern plate, which by means of pivots e
and rests upon and is capable of turning in bearings of the carriage or
the carriages G and G¹; these carriages are capable of running (or may
slide) upon the rails H and H', which are supported on brackets I fixed to
the framework or pillar. J is a rotary shaft supported in bearings J₁ of
the pillar on this shaft are fixed three eccentrics K, K', and K³, also
a hand wheel or lever L, by which the said shaft is turned; M are bosses
or bushes attached to the moulding table, and capable of sliding in brackets N
fixed to the pillar; P are rods capable of sliding in the bushes M, and which
rest upon and are operated by the eccentrics K and K'; to the top ends of
these rods are fixed lifters or arms R, by which the top box D is lifted and
lowered. The stem of the table B rests upon and is operated by the
eccentric K³ for lifting and lowering the said table.
Fig. 3 is a plan view of the plate E, carriages G and G', with portions of
the rails H.
The mode or manner of working this machine is as follows:-The part D
of the moulding box is placed upon the table B, and the other part C upon
the arms R; then by turning the shaft J the two parts are brought into
contact with the plate E, one on each side thereof, and secured thereto by
cotters passing through the pins c, d, in the usual manner, as shewn in the
middle part of Fig. 2. The part C is then rammed up in the ordinary
manner, and the carriages with the plate and boxes are run on the rails to
the position shewn at the left side of Fig. 2; the boxes and plate are then
turned over (the plate turning on its pivots), and the carriage moved back
to the middle of the machine, when the box D, which is topmost, is then
rammed up in the usual way; after this has been done the cotters are
removed and the two parts of the moulding box separated from the plate by
turning the shaft J, the said boxes being placed as shewn at Fig. 2, when
the plate is run or slided out to the position shown to the right hand of the

page_text: machine; the two parts of the box are then brought together by turning the
shaft, and they are then ready to be removed for casting or pouring in of the
molten metal.
The second part of my Invention is illustrated at Figs. 4 and 5, which are
respectively elevation and plan of a machine or apparatus constructed in
accordance therewith. A is the frame or pair of pillars which support a
shaft B or axes with arms C projecting therefrom, to which the pattern
plate D is affixed; E and F are the pair of moulding boxes, which are
guided to their proper place by pins G and H. Stands I are fixed on the
plate, and cotters J are passed through holes therein to hold the said boxes
on the plate during the ramming process. K is a counterweight attached by
an arm L to the shaft or axes to balance the weight of the boxes, and which
weight is capable of adjustment by screws and nuts M.
The method of working this machine is as follows:-The boxes being
placed and secured as shewn in the Drawings, resting upon a table or
bracket N, the upper box E is rammed up, and then the shaft or axes are
turned, transferring the said boxes to the opposite side of the axes, by
which they are turned over, the part E being thereby placed undermost
and resting on another table or bracket P; the part F is then rammed
up, and the part E is detached from the plate; the axes are then turned
back, carrying the part E to the table N, when it is also detached from
the plate and the plate removed from it. Both parts are now ready to be
removed by hand from the tables and placed together to receive the moulten
metal..
In witness whereof, I, the said Joseph Smith, have hereunto set my
hand and seal, this Fourth day of April, One thousand eight hundred
and sixty-eight.
Signed, sealed, and delivered by the
within-named Joseph Smith, in
