page_text: We SYLVANUS EDDINGTON and JOHN EVAN STEEVENSON both of Chelmsford in
the county of Essex Engineers, 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:-
This invention relates to improvements in Brick Moulding Machines as described in
Helliers Patent A.D. 1886 No. 4281.
The machine comprises presses for foreing clay into moulds, means for bringing the
moulds into position beneath the press die and removing them therefrom and means
for severing the clay in moulds from the excess remaining in the press prior to
removing the same therefrom.
Reference is to be had to the accompanying drawings forming part of this
specification wherein figures 1 and 2 represent elevations of the press in section.
Figure 3 is part plan and figures 4 and 5 detail view. The same letters of reference
indicate the same parts in all the figures.
The pressing chambers and pistons may be the same as described in Helliers
Patent but the machine is fitted with two treadles N and N¹ these are attached to
chains and O¹ working over pullies S and S¹ and attached to a lever R in this
lever R are 3 slots W, W₁ and W2" attached to the wedges H are two studs X which
drop into slots W and W. The wedges H instead of being inclined planes are made
in steps giving an intermittent motion to the rise and fall of moulds as shown. The
slot Win lever R works connecting rod S which actuates the cutting off
frame D it will be seen that the slot. We allows some motion of the lever R and
therefore of the wedges H before moving the cutting off frame the object of this
is to allow the wedges to come down one step giving sufficient room for the cutting
wire or knife to go between the mould and die it then cuts off without any further
drop but the next step when the clay in mould has been severed from that in the
chamber attached to the stock carriage G is a wire or chain M passing over pulley I
and coupled to the lever K which carries a weight L' which can be moved to any
position on the lever K giving a greater or less pull on the wire M as desired.
Attached to the main frame of the machine is a bracket P carring a spring Q which
presses against the stock carriage G when the same is under the clay chamber A.
On the stock carriage G is a projection U and attached to main frame of machine is
a fixed projection T and a jointed catch V the object of this is to hold the stock
carriage G under the chamber A until the mould is filled and clay severed. The
action of the same is as follows when the wedge H is in the lowest position the
attendant pushes the stock carriage G carrying the mould F under the clay chamber A
raising the lever K and weight L and compressing the spring Q until the projection U
passes and is held in position by the catch V he then works the treadle N which as
described before works the wedge H and raises the projection U above and out of
gear with the catch V it then comes in contact with the stop T where it remains

page_text: until the mould is filled and the clay severed as soon as this is. done the stock
carriage is lowered and the projection U drops below stop T and the filled mould F
and carriage G are forced out by the action of the spring and drawn by the
weight L on the lever K by the wire or chain M.
It will be obvious that the various motions may be obtained in many other ways
for instance instead of a treadle lever worked by foot the same action may be
attained by a land lever and that many other methods of constructing catches for
holding moulds in position and releasing same may be adopted we therefore do not
confine ourselves to the particular methods described.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
In Brick Moulding Machines such as described in Hellier's Patent No. 4281, 1886.
1st. The raising and lowering the mould by a treadle lever actuated by the foot.
2nd. The actuating any two or more of the following motions at the same time by
levers worked either by hand or foot, viz. raising and lowering the moulds. Moving
the cutting off frame. Releasing the catch that holds the moulds under clay chamber.
3rd. Drawing or forcing the stock carriage and mould from under the clay chamber
after it has been filled and cut off either by wire chain or other equivalent or by a
spring or springs.
4th. Raising and lowering the mould by intermittant motion so that the mould
is stationary or nearly so while the clay in mould is being severed from that in the
clay chamber.
•
5th. Holding the mould under clay chamber by means of catches and liberating the
same when mould is filled and cut off.
