IMPROVEMENTS IN MECHANICAL MOULDERS
Year: 1884

page_text: I JOHN BOWLING of 56 Moor Crescent Hunslet, Leeds, In the county of York,
Ironfounder, do hereby declare the nature of my invention for IMPROVEMENTS
IN MECHANICAL MOULDERS to be as follows:-
A and B are the two side frames. C is a bridge piece binding the two side
frames together. D is a "Gun metal" nut, or female screw fitted into C.
E is a male screw used for lowering and raising the platten F; upon which is
securely fixed the pattern holder G; and upon which is fixed the pattern or
patterns to be moulded.
H, is a sliding table which also acts as a stuffing sand box; and is shown level
with the Ram I. which is made to fit the stuffing sand box in such a manner as to
press all the sand out of the "Stuffing sand box" and into the real moulding box K,
so as to give the required solidity to the mould when it is pressed. L is a large
Hand-wheel fixed on the screw E, the wheel L being of such a diameter and
weight; and the screw calculated to such a pitch as to give the necessary solidity to
the mould by the momentum acquired in descending. M is a Cross-frame serving
three purposes. 1st The binding together of the lower part of the Side-frames.
2nd It forms an adjustable socket for holding the Ram I 3rd It also has a long
boss near to each end, which is bored out so as to fit the turned Pillars S. S. which
support the movable table H; and thus acts as a slide for the movable table. R, is
a fulcrum shaft on which the Levers T, T, by means of the Balance weights raises
the sliding table H, to the level of the Ram after the pressure is removed.
U is a
foot lever by which the moulder may hold down the Sliding table if he require it.
The machine is shown in the drawing in its original position.
The Ram I forms the bottom of the Stuffing sand box. The moulding box is
placed on the top. The sand is shovelled in. The stuffing sand box and moulding
box are full of unpressed sand. The Patterns are suspended from above. A sharp
turn of the wheel L, brings down the patterns, they enter the sand; and the pattern
holder following alights on the moulding box carrying it and the sliding table
downwards. During this operation the Ram I is fixed and in consequence has
forced the sand in the stuffing sand box up into the moulding box, the bottom of
which it now forms. And the mould is perfectly solid. A smart rap or two with
a wooden mallet on the top of the platten F loosens the patterns a little. The
action of the wheel L is reversed; the patterns are withdrawn, and the moulding
box removed, and another substituted. This machine is also made with an inverted

page_text: Ram, for occaisional use, when castings of great depth are moulded. In these
circumstances a Stuffing sand box, or duplicate moulding box is placed on the top
of the real moulding box; and the Pattern holder G becomes a Ram also, travelling
inside the top Stuffing sand box. Thus if needs be, the raming can be done on the
top and bottom conjointly.
The Applicant claims to have invented; and asks to be protected from any
infringement of design or method of working. And also claims the sole right of
making and selling (agents excepted) "Bowling's Mechanical Moulder" wherever
the protection of the "Patent Act" extends.
The following is a list of the special features for which protection is claimed.
1st The Applicant believes this machine to be new in design; and dissimilar to
any machine manufactured for the like purpose. And he asks to be protected from
any infringement of this.
2nd The Applicant admits that certain features of the machine such as the Wheel
and screw Etcet though not new in mechanics; yet are new in their combination
for this particular purpose. And the Applicant asks protection from infringement
of this.
3rd Certain features of the machine which the Applicant considers to be the
vital principle, and an original conception, are 1st "The Sliding Table and Stuffing
sand box"
2nd The fixed Ram with its adjustible socket 3rd The inverted Ram
and Stuffing sand box. 4th The sliding Pillar motion for raising and lowering the
Sliding table.
The Applicant claims to make this machine in its larger sizes; with additional
screws, and to be driven with power.

page_text: I JOHN BOWLING of 56 Moor Crescent Hunslet, Leeds do hereby declare the
nature of my invention for IMPROVEMENTS IN MOULDING MACHINES and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :—
A and B are the two side Frames.
C is a Bridge piece binding the two side frames together.
D is a Gun-metal nut or female screw in two halves fitted into C.
E is a male screw used for lowering and raising the Platten F upon which-in
the most general form of working this machine-is securely fixed the pattern
holder G. which pattern holder may be either a Plaster block, or iron, or wood.
His a Sliding table, acting also as a Stuffing sand box. The bottom of which
is shown level with the Ram I.
I is a Ram made to fit the interior of the Stuffing sand box with exactness, so as
to press all the sand out of it into the real moulding box. J, thus giving the required
solidity to the mould when pressed.
K is a large Hand-wheel fixed on the screw E The wheel K being of such a
diameter and weight, and the screw calculated to such a pitch as to give the
necessary solidity to the mould by the momentum acquired in descending.
L is a Cross-frame serving two purposes 1st the binding together of the lower
part of the Side-frames 2nd it forms an adjustible socket for holding the Ram I.
M. M. are two turned Pillars sliding in two long bosses fixed on the outside of
the side frames. These Pillars have a boss in the centre bored out, and through
which the neck of the Stuffing sand box passes; and by means of which the
Stuffing sand box can be made to revolve when necessary. The two pillars
continue upwards from this boss and pass through an extremity of the Platten F
and to which they can be coupled when moulding with the patterns at the bottom.
N is a fulcrum shaft on which the levers O. O. by means of the Balance
weights P. P. raises the sliding table to the level of the Ram after the pressure as
been removed.
Qis a foot lever by which the moulder may hold down the Sliding table if he
require it.
R. R. are two screws acting as stoppers to the balance weights P. P. thereby
serving as adjusters to the Stuffing sand box.
S. S. are two Pins screwed into carriers of bottom pattern plate, and passing
through the arm of Stuffing sand box and the handle of the moulding box; serving
as a guide for the moulding box; and in the case of turning over motion being
used, for cottaring together the three parts indicated.
T. is a set screw tightening the two halves of the Gun-metal nut and preventing
the running down of the machine.
The
Mode of operation 1st Ordinary method The Ram I forms the bottom of the
Stuffing sand box. It may be used alone or have a pattern plate on the top of it.
The moulding box is placed on the top of Stuffing sand box. The sand is shovelled
in. The Stuffing sand box and moulding box are full of unpressed sand.
patterns are suspended from top Platten. A sharp turn of the Wheel brings down
the patterns, they enter the sand, and the pattern holder following alights on the
moulding box, carrying it and the sliding table downwards. During this operation
the Ram being fixed has forced the sand in the Stuffing sand box into the moulding
box the bottom of which it now is, and the mould is perfectly solid.
A smart rap

page_text: or two with a wooden mallet loosens the patterns a little. The action of the
Wheel is reversed; the patterns are withdrawn; and the moulding box removed
and another substituted.
2nd Special method of working the machine by means of which the patterns can
be moulded from the bottom in cases of difficulty when moulds require venting, or
a preliminary manipulation by the human band. In such cases the patterns are
affixed to a pattern plate exactly fitting the interior of the Stuffing sand box. To
each end of this pattern plate underneath, is securely screwed a wrought iron
carrier; this carrier descends through a loop cut in each end of the Ram. It
descends sufficiently low to allow travelling distance for the Stuffing sand box.
Then these Carriers turn towards the Side-frames. In the outer ends of these
carriers are screwed the two Pins S. S. with cottar hole in the top of them. These
Pins pass through the arm of the Stuffing sand box, and through the flat handle of
the moulding box. Upon this bottom pattern plate the patterns are fixed. And
the sand is filled in over them. When the pressing is done a cottar is driven in
over the top of the moulding box handle, and thus pattern plate, Stuffing sand box,
and moulding box are securely fastened together. The two turned pillars under
this method are coupled to the top Platten, which travelling upwards raises the
Stuffing sand box, the moulding box, and pattern plate. As soon as these clear the
Ram sufficiently, they are turned over, then lowered until the moulding box-bottom
downwards is deposited on the Ram. The cottars are then withdrawn, thus freeing
the moulding box; whilst the Stuffing sand box and pattern plate are raised and
withdrawn by the action of the Wheel and screw.
This machine is also made with an inverted Ram for occaisional use when
castings of great debth are made.
In these circumstances a stuffing sand box or duplicate moulding box
placed on
the top of the real moulding box. The top pattern holder becomes a Ram also,
travelling inside the top stuffing sand box. Thus if needs be the ramming can be
done on the top and bottom conjointly.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is
(i) The sliding table or stuffing sand box substantially as and for the purpose
hereinbefore described.
(ii) The adjustible ram substantially as and for the purpose hereinbefore
described.
(iii) The inverted ram and stuffing sand box substantially as and for the purpose
herein before described.
v
(iv) The sliding pillar motion for raising lowering and turning over the sliding
table or stuffing sand box, substantially as and for the purpose herein before
described.
Dated this 1st day of October 1884.
