SPECIFICATION.
Improvements in and relating to Brick-making Machinery.
I, GEORGE HALL of 82, Queen's Gate, Burnley, in the County of Lancaster, Brick
Work's Manager, do hereby declare the nature of this invention to be as follows:-
This invention is designed, for the lubrication of the moulds of brick making
machinery, to effect a considerable reduction of power in driving the machine; and
for the production of a much superior surface or skin to the brick when made. In
carrying out my invention I form two chambers, one above another in the lower
mould block. The upper chamber contains oil or other lubricant for the lubrication of
the surface of the mould; whilst the lower chamber is supplied with steam, to warm
and dry the surface or interior of the mould to assist in preventing the adhesion of the
clay to the sides of the mould after the compression of the clayey particles. In
addition to the oil or lubricating chamber above described, I employ a supply cistern
situated immediately below the brick discharging surface of the machine. This cistern
is connected by a flexible pipe to the lubricating chamber of the mould block, so as to
allow the block free action in its vertical movement.
Near the upper edge of the mould block is formed a groove, in which is placed
suitable packing which takes up the lubricant and transmits it to the sides of the
mould, small orifices being formed in the block, as a means of communication for the
oil from the interior of the oil chamber to the exterior, to supply the packing. A tap
may be used, if desired, to regulate the supply of oil from the cistern to the lubricating
chamber.

COMPLETE SPECIFICATION.
Improvements in and relating to Brick-making Machinery.
I GEORGE HALL of 82, Queen's Gate, Burnley, in the County of Lancaster, Brick
Work's Manager, 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 is designed for the lubrication of the moulds of brick making
machinery, to effect a considerable reduction of power in driving the machine; and
for the production of superior bricks.
And in order that my invention may be properly understood, and readily carried
into practical effect, I have hereunto attached the accompanying sheet of drawings,
marked with figures and letters of reference; the same letters referring to the same
parts in the various figures.
Fig. 1 is an elevation in section of a brick machine constructed in accordance with
my invention. A is the feed hopper; B a carrier which conveys clay from the hopper
to the mould C; D. D. are side plates or parts of the mould; E a flexible tube
through which steam is conveyed to the interior of the mould block H to dry and warm
the surface of the mould and prevent the adhesion of the clay to the sides of the mould
after the compression of the clayey particles; and F represents the upper mould block
or presser which moves vertically in guide ways G. The parts above enumerated are
old and well understood and form no part of my invention.
Beneath the presser plate H¹a layer of packing I is inserted which beds against the
surface of the mould, and is supplied with oil or other lubricant from cistern J through
flexible tube K and vertical pipe K' to lubricate the mould. In Fig. 2 which is an

page_text: enlarged view in transverse section is shown more clearly the arrangement of the
lower mould block H and parts connected therewith. This mould block, to which my
invention more particularly relates, is provided with two chambers J and J2 the
former for the reception of oil and the latter for steam for purposes above described.
In the mould block H, small orifices L are formed communicating with the interior
and exterior of the chamber J¹ to supply the packing or absorbent material 1 with oil
or other lubricant which is transmitted to the surface of the mould while the mould
block is expressing therefrom compressed bricks.
Fig. 3 is a plan view showing the side walls D D and E' E' of the mould within
which the mould block H moves vertically in expelling the bricks. In this view is
represented a modification of my invention, consisting of a perforated tubular frame O
rectangular in form, in substitution of the oil chamber J¹; the presser plate H heing
removed to expose the tubular frame O, which is partially enclosed within the
packing I.
Fig. 4 is a plan view of the mould block H and the perforated tubular frame O with
the packing removed showing more clearly the perforations in the tubular frame.
Fig. 5 is an elevation in section of the lower mould block H, in which view the
lubricating chamber J' is dispensed with and the perforated rectangular frame O
substituted.
In substitution of the absorbent material above described as packing, fine copper
wire or brass may be used sufficiently ductile to properly bed itself against the side
walls of the mould.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
The arrangement and combination with the lower mould block H of the parts for
the lubrication of the surfaces of the moulds of brick making machinery, substantially
as described and illustrated.
