Improvements in Apparatus for Making Bricks, Tiles, and similar
Articles from Plastic Clay and the like.
I WILLIAM SAYER of 144 Uttoxeter New Road Derby in the county of Derby,
Engineer do hereby declare the nature of this invention to be as follows:-
My invention relates to improvements in machinery or apparatus for making bricks,
tiles or the like from plastic clay or similar material and in carrying it out I provide
improved means for cutting the slab of clay or like plastic material whereby such.
operation can be readily effected by motive power, say, for instance as by steam, in
place of by hand.
I pivot a radial or rocking link or arm which operates the cutter to the frame
or bed plate.
This link or arm is rocked or oscillated to and fro by reason of a crank block or piece
engaging in a slot therein and which crank block or piece is mounted on a disc or
plate through this disc or plate passes a shaft running freely and on this shaft is
keyed a ratchet wheel. On another disc connected by a sleeve to the crank disc or
plate is pivoted a pawl set up by a spring to the ratchet wheel on the shaft.
When the ratchet wheel is revolved it carries the pawl forward until it comes in
contact with a sliding bolt held in position by a spring or weight, this bolt releases
the pawl from the ratchet wheel.
:-
In this position the crank disc or plate and radial or. rocking link or arm
remain at rest until the sliding bolt aforesaid is pulled back by band lever or
other device.
Each operation of this lever causes the crank disc or plate to make one revolution.
and the radial or rocking arm or link to make one vibration or oscillation which
rocking link or arm being connected to the pushing bar and push board makes one
complete cut of bricks, tiles &c. on the cutting table and the cutter then returns to its
normal position; the table is then ready to receive a fresh column of clay.
The radial or rocking link or arm is so arranged that during the cutting stroke the
crank block or piece and crank pin traverse the upper and longer radius of the link
or arm giving a slow, strong forward stroke for the cut, but on the backward stroke
the crank block or piece and crank pin traverse the lower and shorter radius of the
arm giving a quick return to the normal position.
Respecting the pan bars usually employed in the edge runner pan or mill I intro-
duce a wooden or like cushion with or without a longitudinal iron bearer above the
wood or like cushion so as to as far as possible prevent noise and wear.
It will be seen that my cutting apparatus may be adapted for use in any kind
of side delivery cutting table for any purpose and to existing hand cutting machines.

Improvements in Apparatus for Making Bricks, Tiles, and similar
Articles from Plastic Clay and the like.
1 WILLIAM SAYER of 144 Uttoxeter New Road Derby in the County of Derby
Engineer, 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 :-
The object of my invention is to provide improved means or apparatus for cutting

page_text: a slab of clay or like plastic material, whereby such operation can be readily effected
by motive power, say for instance steam, in place of by hand.
Referring to the accompanying drawings and to the figures.and-letters. of- reference
thereon indicated
Figure 1 is a side elevation of my invention applied to a cutting table.
Figure is a sectional elevation on line a--a of figure 1.
Figure 3 is a sectional elevation through the driving shaft shewing ratchet wheel
pawl and spring.
Figures 4 and
illustrate method of operating bolt I.
Figure 6 is a section through one side of my improved pan bars.
In carrying out my invention I pivot a radial or rocking link or arm A which
operates the cutter, to the frame or bedplate B this link or arm is oscillated or rocked
to-and-fro by reason of a crank block or piece (engaging in a slot, therein and which
crank block or piece is mounted on a disc or plate D.
Through this disc or plate D passes a shaft E running freely.
On this shaft E is keyed a ratchet wheel F. On another disc G connected by a
sleeve to the crank disc or plate D is pivoted a pawl H set up by a spring J to, the
ratchet wheel on the shaft, when the ratchet wheel is revolved it carries the pawl
forward until it comes in contact with a sliding bolt I held in position by a spring J
or by a weight, this bolt releases the pawl from the ratchet wheel on striking the
same.
In this position the crank disc or plate D and radial or rocking link or arm A
remain at rest until the sliding bolt J aforesaid is pulled back by the hand
lever K and rod K¹ or other suitable device. To prevent disc G, working back a
notch is left in its outer edge (Fig. 3) to engage with a spring J³.
Each operation of this lever K causes the crank disc or plate D to make one
revolution and the radial or rocking link A to make one vibration or oscillation
which rocking link or arm A being connected to the pushing bar L and push
board M makes one complete cut of bricks. tiles &c., on the cutting table M' and
.then returns to its normal position. The table M¹ is then ready to receive a fresh
column of clay or the like.
The radial or rocking link or arm is so arranged that during the cutting stroke the
crank block or piece Cand. crank pin C traverse the upper and longer radius of the
link or arm A giving a slow strong forward stroke for the cut, but on the backward
stroke the crank block or piece. C and crank pin C traverse the. lower and shorter
radius of the arm giving a quick return to the normal position.
In regard to the pan bars N usually employed in the edge runner pan or mill. I
introduce a wooden or like cushion O with or without a longitudinal iron or metal
bearer P above the wood or like cushion, so as to as far as possible prevent noise, wear,
tear and breakage.
I have shewn a belt pulley Q on the shaft E but gearing may be employed either of
spur bevel or other suitable variety.
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
First:The combined arrangement of apparatus for making bricks tiles and the
like from plastic clay or other suitable material substantially as described and
illustrated in Figures 1 to. 5. on the accompanying sheet of drawings.
Second-
Constructing pan bars for use in edge runner pans or mills for treating
plastic clay or like material substantially as and for the purposes described and
illustrated in Figure 6 of the accompanying drawings.
