Improvements in and connected with Wire Cut Machines for Making
Bricks and the like.
I, FREDERICK LINDLEY HUNT SIMS, of 158, Simcoe Street, in the City of Toronto,
in the County of York, in the Province of Ontario, Canada, Manufacturer, 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:-
My invention relates to improvements in clay working machines in which the
clay after being delivered from the machine is cut off in desired lengths by means
of what is commonly known in the art as a wire cut and the object of the inven-
tion is to design a simple, cheap and easily driven machine of this class by which
the pug clay from the pug mill may be compressed and delivered from the die
in convenient form for cutting and it consists essentially of a drum journalled on
a shaft supported in suitable standards and provided with a series of pivoted
compresser wings, the drum being partly surrounded by a concentric receiving
chamber ending in a tangential compressing chamber and die-plate preferably
located at the bottom of the machine, an orifice being provided in, the receiving
chamber for the conveyance of the pug clay from the pug mill into such chamber,
the machine being driven and the parts being otherwise arranged and constructed
as hereinafter more particularly explained.
Fig. 1, is a perspective view of a machine constructed in accordance with my
invention
Fig. 2, is a longitudinal sectional elevation through the machine.
Fig. 3, is a cross sectional elevation.
In the drawings like letters of reference indicate corresponding parts in each
figure.
A is a drum, which is supported by suitable spokes B and hub B¹ upon the
shaft C. The hub B is loosely journalled on the shaft and is designed to rotate
freely thereon. Each spoke B is provided with a web b extending out from one
side thereof to the rim of the drum.
The shaft C is suitably keyed or otherwise secured in the standards D. E, E¹
are gear rings forming part of or secured to the outside faces at the rim of the
drum A. Fis the main driving shaft, which is journalled in suitable bearings
and is provided with gear pinions G, G¹, which mesh with the gear rings E, E¹
respectively and from which such drum is driven.
His a receiving chamber, which extends partially around the periphery of
the drum, is U-shaped in cross-section and is supported at the top by a rod d.
which extends through a lug h attached to or forming part of the outer wall of
the chamber, into the top of the standard D. The inner edges of the sides H¹
of the chamber H fit into peripheral grooves a, which extend around the entire
periphery of the drum in juxtaposition to the gear rings E and E.

orifice made preferably in the pheripheral side of the compression chamber. H² is

bottom of the machine as indicated and forming an extension of the receiving
chamber H. I are quadrantal cams secured to the shaft C and provided with
broadened peripheral faces I'.
".
.
The upper end of each cam is preferably made vertical as indicated in the
drawings while the other end is cut off obliquely, so that the length of the cam
is less than a half circle. The ends of the cam are rounded off into straight
radial portions as shown.
A are broad openings preferably four in number made in the peripheral face
of the drum A.
*.*..
A2 are inwardly extending lugs made in each side of the drum towards one
end of each of the openings A. J are the wings. Each wing J has a com-
pressing side at the inner end of which is an enlargement through which
passes a rod 2, which extends into the side lugs A2 and forms a pivot for the
wing J.
Je is a convex back extending rearwardly from the compressing side J
and are rearwardly extending sides enclosing the space between the com-
pressing side and back J. jare friction rollers journalled on pins j in the
inward extensions J4 of the sides J³.
The back is concentric to the rod j³.
H³ is a die plate, which is fastened on the end of the walls of the compressing
chamber H².
The die plate H³ may be of any suitable form, this of course depending on the
style of goods it is desired to turn out.
I do not particularly describe the die plate and I may merely mention that
there is a liquid lubricator for the clay as it issues from the die plate. I may
also mention that I may provide means between the wings, so that upon the
raising of each wing at the top of the machine the usual wire cut apparatus may
be operated intermittently to sever the clay into desired lengths but I do not
wish to make any claim upon the particular method of accomplishing this result
in this application as such means are to form the subject matter of a separate
application.
Having now particularly described the principle parts involved in my invention
I shall briefly describe the operation of the machine.
The pug clay is fed in as hereinbefore premised from the pug mill through, the
orifice into the receiving chamber H. As the drum is caused to revolve it will
be readily seen that cach wing J as the rollers ja pass up the vertical side of the
cam I will be caused when they reach the concentric portion of such cam to raise
so that the compressing side is substantially radial to the centre of the shaft.
When it has reached this position it will be noticed from the construction
described that it will have entered the receiving chamber H. In passing around
the receiving chamber as indicated, each wing J will sweep before it the pug clay
fed in through the orifice h and will carry it forward and compress it in the
tangential chamber H. When the compressing wing J has reached the position
shown at the bottom of Fig. 2, it will be readily seen that the rollers will
have passed the end of the cams and consequently the back pressure from the
now compressed clay as the drum revolves will cause the compressing wing to
recede into the drum, so that it will assume the position shown by the compressing
wing at the right hand side of the figure. Each wing as the drum revolves is
necessarily actuated in the same way and any little pug clay which may accumu-
late from the pug mill behind the arc-shaped back of the compressing wing will
necessarily be carried forward by the succeeding wing.
From this description it will be seen that I devise a machine in which the com-
pression may be carried on intermittently with a minimum amount of power and less
loss of time than any other machine devised for the purpose of which I am aware,
the advantages of the intermission being that the wire cutting of the product
can be accomplished during the same, avoiding the expense of cutting tables.
It will also be noticed that my improvement does away with the twisting and

page_text: warping of the material before delivery through the die, the most serious defect
incident to machines now commonly in use.
Having now particularly described and ascertained the nature of my said in-
vention, and in what manner the same is to be performed, I declare that what I
claim is:-
_
1. In a clay working machine, in combination, the casing, the rotary drum,
the compressing wings pivoted within openings in said drum, and having inwardly
extending portions, and the stationary cam located within the circumference of
the drum and designed to act on the inwardly extending portions of the wings,
substantially as described.
2. In combination the drum having peripheral openings, the stationary cam,
the receiving chamber, the independent compressing chamber and the pivoted
wings adapted to be operated to move in one direction by said cam and to move in
the opposite direction by said compressing chamber, substantially as described.
3. In combination the drum having peripheral openings, the stationary cam,
the receiving chamber, the independent compressing chamber, and the wings
adapted to be thrown outward by said cam, and inwardly by contact with the
compressed clay in the said compressing chamber, substantially as described.
