Improved Means of Lubricating Moving Bars of Clay in or Con-
nected with Machinery for the Manufacture of Bricks, Tiles,
Drain-pipes, and the like.
I, WILLIAM ILLSLEY, of Woodville, Burton-on-Trent, Leicestershire, Brickyard
Contractor, do hereby declare the nature of this invention to be as follows:-
This invention consists of the improved means herein described of lubricating
moving bars of clay in or connected with machinery for the manufacture of bricks,
tiles, drain-pipes and the like, as for instance a moving bar of clay on the cutting-off
table of brick, tile or drain-pipe machines, or in the passage of the bar of clay from
the die to the cutting off table.
Heretofore a peculiar kind of vegetable oil having a very disagreeable odour has
generally been employed for this purpose and applied to the underside of the moving
bar of clay by means of a roller or rollers running in the oil and over which the bar
of clay passes.
The disagreeable odour from this oil is known to be injurious to health and
moreover the oil is comparatively expensive.
According to my invention I lubricate the underside of the moving bar of clay by
water or a thin mixture of clay and water technically known as "slip" in the manner
which I will now describe.
For the purposes of my invention the table or platform (usually and by preference
formed of wood) along which the bar of clay slides has at certain intervals excavated
chambers or depressions on its upper surface preferably of about the same width as
the bar of clay passing over them. Each of these chambers is covered with perforated
sheet zine or other suitable perforated or porous substance and on the top of the zinc
is a layer or layers of fustian, felt or other like material. Each of the chambers is
supplied with water or "slip" at a slight pressure by means of suitable pipes so that
the water will be absorbed by and ooze through the fustian or the like on the top
thereof. As the moving bar of clay passes over the chambers it is perfectly lubricated
by the water or "slip" oozing up through the fustian covers thereof.
The fustian or other like material on the chambers is by preference arranged in the
form of two flaps the edge of one overlying the other and each fixed only along that

page_text: edge which meets the advancing clay so that the fustian or other like material can
readily be turned up to examine the perforated grating beneath.
In a modification of my invention the table or platform along which the bar of clay.
slides is perforated at certain places (instead of being formed into chambers as above.
described) for the water or "slip" to pass up through, these perforations being 5
covered by fustian or the like as above described, and in this case the perforated
zinc may be dispensed with.

Improved Means of Lubricating Moving Bars of Clay in or Con-
nected with Machinery for the Manufacture of Bricks, Tiles,
Drain-pipes, and the like.
I, WILLIAM ILLSLEY, of Woodville, Burton-on-Trent, Leicestershire, Brickyard
Contractor, 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 consists of the improved means herein described of lubricating
moving bars of clay in or connected with machinery for the manufacture of bricks,
tiles, drain-pipes and the like as for instance a moving bar of clay on the cutting-off
table of brick, tile or drain-pipe machines or in the passage of the bar of clay from the
die to the cutting-off table.
Heretofore a peculiar kind of vegatable oil having a very disagreeable odour has
generally been employed for this purpose and applied to the underside of the moving
bar of clay by means of a roller or rollers running in the oil and over which the bar
of clay passes.
The disagreeable odour from this oil is known to be injurious to health and
and moreover the oil is comparatively expensive.
According to my invention I lubricate the underside of the moving bar of clay by
water or a thin mixture of clay and water technically known as "slip" in the manner
which I will now describe.
For the purposes of my invention the table or platform (usually and by preference

page_text: formed of wood) along which the bar of clay slides has at certain intervals excavated
chambers or depressions on its upper surface preferably of about the same width as
the bar of clay passing over them. Each of these chambers is covered with per-
forated sheet zine or other suitable perforated or porous substance and on the top
of the zinc is a layer or layers of fustian, felt or other like material. Each of the
chambers is supplied with water or "slip" at a slight pressure by means of suitable
pipes so that the water will be absorbed by and ooze through the fustian or the like
on the top thereof. As the moving bar of clay passes over the chambers it is perfectly
lubricated by the water or "slip" oozing up through the fustian covers thereof.
The fustian or other like material on the chambers is by preference arranged in the
form of two flaps the edge of one overlying the other and each fixed only along that
edge which meets the advancing clay so that the fustian or other like material can
readily be turned up to examine the perforated grating beneath.
"
In a modification of my invention the table or platform along which the bar of clay
slides is perforated at certain places (instead of being formed into chambers as above
described) for the water or slip" to pass up through, these perforations being
covered by fustian or the like as above described, and in this case the perforated zinc
may be dispensed with.
On the accompanying drawing Fig. 1 represents in longitudinal sectional elevation,
Fig. 2 in cross section and Fig. 3 in plan part of a table or platform with my
invention applied along which a bar of clay is required to move; Fig. 4 is a plan,
Fig. 5 a longitudinal sectional elevation and Fig. 6 a cross section of part of the table
or platform illustrating a modification of my invention.
The same letters of reference indicate corresponding parts in all the Figures.
Referring firstly more particularly to Figs. 1, 2 and 3, A is the table or platform
(in this case made of wood) along which the bar of clay B slides for instance as it
issues from the die of the brick machine and passes to the cutting-off table. The
excavated chambers or depressions on the upper surface of the table or platform A
are marked and the perforated zinc or the like with which they are covered is
marked and EE are the layers of fustian, felt or other like material on the top of
the zinc. The fustian, felt or other like material is by preference secured only along
that edge e (which may be done by nailing to the table) which is towards the
advancing bar of clay B, this allows of the other edges being turned up to examine
the perforations underneath. fff are the three branches of the
pipe F which
respectively enter the chambers c and supply them with water or slip" which passes
through the perforated gratings d and is absorbed by and oozes through the fustian
or the like on the top thereof so as to perfectly lubricate the moving bar of clay B
as it passes over them. In Fig. 3 the fustian or like covers E E of the central
chamber are removed so as to shew the grating d underneath and from the right hand
chamber in Figs. 1 and 3 both the covers E E and grating d are removed to shew
the excavated chamber.
<<
In the modification illustrated by Figs. 4, 5 and 6 the perforated metal gratings d
are dispensed with and instead thereof the wooden table A itself is perforated by
small holes marked g which communicate with a large transverse hole / bored in from
the side of the table and into which the end of the water or "slip" supply pipe fis
inserted. The holes g are by preference bored in a slanting direction (see Fig. 5)
so as to deliver the water in the direction in which the clay is moving. In this
modification the fustian or other absorbent cover of the holes may sometimes with
some clays be dispensed with as if the holes g are bored as slanting as possible they
will not get stopped up by the clay.
In conclusion I would have it understood that my invention is not limited to the
precise details herein described and illustrated as the same may be varied without
departing from the nature of my invention, as for instance the table or platform A
may be of metal and the slanting holes g may be in several rows in a separato metal
or other grating through which the water or "slip" passes and the perforations may
be of any other shapes than that shewn such for instance as narrow slits.
