PROVISIONAL SPECIFICATION.
Automatic Brick Cutting Table and Counter.
I, DAVID LUCIFER MARTYN Engineer 3 Coquet Street Hebburn on Tyne do
hereby declare the nature of this invention to be as follows:-
A machine driven by power and worked direct from the brick mill itself, which
has three spur wheels running together two having clutch wheels gearing into them.
One is used for cutting off a clot of clay to make a certain number of bricks the
other is to move a table carring the clot with it, also to work a segment of a spur
wheel into a rack to press the clay against a number of wires to form bricks.
These bricks being counted by a counter worked from off a shaft upon which
there is an eccentric carring a rod which actuates upon a pawl-wheel moving one
tooth at a time for each number of bricks so cut. There are also the neccessary
levers to throw clutch wheels out of gear, and a wheel loaded with a certain weight
which when clutch wheels are thrown out of gear brings pusher, table, etc. into the
neccessary position for the next clot of clay coming through the mill.
Dated this 7th day of March 1893.

Automatic Brick Cutting Table and Counter.
DAVID LUCIFER MARTYN 3 Coquet Street Hebburn on Tyne 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 -
In the brick cutting tables hitherto constructed the constant service of an
Moreover in using
attendant is required to put in motion the cutting mechanism.
such brick cutting tables there is frequently considerable waste by leaving short
pieces at one or both ends of the clot of clay, which waste pieces have to be worked
through the clay mill again. The object of my invention is a brick cutting table
and counter perfectly automatic in its action, and therefore not requiring an
attendant to put in operation the cutting mechanism, which avoids the production
of waste ends, and to which is connected a counting attachment for recording the
number of bricks cut.
My invention consists of a machine the construction of which I will now proceed
to describe with reference to the accompanying drawings, on which
Fig. 1 is a plan (partly in section) Fig. 2 a side elevation (also partly in section)
and Figures 3 and end elevations.
A moving table T is operated by the attached rack A' and segmental spur
wheel A keyed on to shaft B to which also are keyed at a little distance apart the
disc wheels H and Ho, and bevil wheel B' which is driven by another bevil
wheel D" on the shaft D. On shaft D are also the segmental spur wheel 6 (giving
by means of rack 6' intermittent rectilinear motion to the pusher P) rope sheave 8
(wound round which is a rope having suspended to its loose end a balance
weight X X not shewn in drawings working in an underground well the mouth of
wwhich is seen in Fig. 1), loose spur wheel I and clutch wheel 5. Spur wheel 1 is
driven by the spur wheel 2 on the continuously revolving shaft A³ connected by
belt or tocthed gearing with the clay mill or other motor.

page_text: Spur wheel 2 also drives loose spur wheel 3 on shaft O on which also is fixed
cam V, clutch wheel 4, striking roller S and crank Y. Clutch wheel 4 is inter-
mittently thrown into gear with spur wheel 3 by the motion of stop lever H¹
operating through rod J, lever H³ rocking shaft G and forked lever H. The
clutch wheel 4 is thrown out of gear by the disc wheel H acting through the
hooked rod Hb, lever H³, rocking shaft G and forked lever HA. Crank Y by
means of the connecting rod Y', moves the bell crank lever Y the upper end of
which presses against and gives motion to the arm CI carrying the cutting wire E,
the return motion of the arm being effected by the balance weight X. (Cam V
Lifts oue end of the lever VI-hereafter called a " stopper "-depressing the other end
which rests in a notch formed in the lower side of table T thus leaving the latter
free to move longitudinally.)
Striking roller S fits loosely on stud, S which is firmly secured to shaft O by the
boss S. This striking roller intermittently strikes the side of a horizontal lever
(not shewn in drawings) which throws clutch wheel 5 into gear with spur wheel 1.
At the proper time the clutch wheel 5 is thrown out of gear by the disc wheel Ho
acting through the hooked rod H00, rocking shaft Go, crank lever H, and forked
lever G. The stop lever Q is free to move slightly round a vertical axis on the
pin H to which it is attached, which passes through a suitable hole in the table T
and which bears on its lower extremity the stop lever H¹. Behind each of the
spur wheels aud 3 is a saucer spring which allows of compression in case the
teeth of clutch wheels ride momentarily. The roller M revolves in a receptacle-
kept filled with oil--cast in the table T and serves to lubricate the bottom surface
of the clay arriving from the clay mill. At each extremity of the table T are two
standards N. N supporting the bar N suitably attached to which are the upper
ends of (say), eleven, cutting wires KI... the lower ends of which are secured to
the table itself. Fastened to the arrival end of the table T are two knees NE NE
having a hole in their upper extremity through which pass loosely the upper ends
of levers Z. Z which bear between them the roller M¹.
On the shaft B is the eccentric sheave C which by means of a rod actuates pawl
wheel 7 the spindle of which is connected to the clockwork of any known suitable
registering apparatus. As each revolution of the eccentric sheave indicates the
cutting of a definite number of bricks-say, twelve-(because there are no waste
ends as in existing machines), then each revolution of the pawl wheel 7 indicates
the cutting of as many times that number as there are teeth in the pawl wheel.
From this the indications of the recording apparatus will be readily perceived. The
plate or keep F serves to prevent the pusher P from rising.
The action of the machine is as follows:-Assuming a steady stream of clay
of the right dimensions arriving from the clay mill on the roller M¹, it passes
over the roller M (by which its bottom surface is lubricated with oil) on to the
table T along which it slides until it comes in contact with oue extremity H of
the stop lever Q. (The preceding cycle of movements left the face of the stop
lever Qlying obliquely across the table T with the extremity H nearest the end of
the table at which the clay arrives.) The pressure of the stream of clay against one
end Hof its face moves the stop lever round a vertical axis to the position shewn
in the drawing at right angles to the table. This moves the lever H', rod J,
rocking shaft G and forked lever HA, throwing the clutch 4 into gear with the
constantly revolving spur wheel 3 and giving motion to the shaft Ổ thus turning
the crank Y which by means of the bell crank lever Y" moves the arm CI
transversely and so causing the wire E to cut off a clot of clay of the right length
for making (for example) twelve bricks. The revolution of shaft O also causes
cam V to depress the stopper out of the notch on the underside of the table T thus
leaving the latter free to move longitudinally. By this time the striking roller S
has moved over the horizontal lever putting clutch wheel 5 into gear with the
constantly revolving loose spur wheel 1, which immediately sets the table in motion
carrying with it. the arm C which is now free to be pulled back by the balance
weight X, and as soon as Y has resumed its initial position the stop of the disc

page_text: wheel H comes into contact with the hooked rod H turning the rocking shaft G
and putting clutch wheel 4 out of gear. As soon as the shaft D is put in motion,
through clutch wheel 5 being thrown into gear as already described, the bevil
wheels B and D", shaft B and segmental spur wheel A begin to revolve, and the
teeth in the latter being in gear with the rack A' on underside of table T moves
the table T forward carrying with it the clot of clay previously cut off as already
described. By the time the table has thus moved for a distance of (for example)
fifteen inches, the revolution of segmental spur wheel A has carried it out of gear
and the table thus comes to rest. By this time the teeth in segmental spur wheel 6
have come into gear with rack 6' causing the pusher P to push the clot of clay
against the wires K..." thus cutting it into bricks which are by the same movement
delivered on to the palate placed to receive them. The revolution of segmental
spur wheel 6 has by this time carried its teeth out of gear with the rack 6¹ and the
stop on disc wheel H° strikes the hooked end of rod Hoo which throws clutch
wheel 5 out of gear and allows the weight X X to reverse the motion of shaft D
causing first the return of pusher P to its initial position, and then the return of
the table T, and just before the table T reaches its initial position the rod J comes
in contact with stop lever Q causing the latter to take up its original position
obliquely to the table. This completes the cycle of movements, and everything is
now ready to begin again. I must now however describe what is being done with
the clay arriving in a continuous stream from the clay mill. At the moment when
the clot of clay whose manipulation I have just described was cut off, the new
piece of clay arriving from the mill reached of course to the wire E. The forward
movement of the table T drew the latter away from this freshly arriving end of
clay, but at same time it drew with it the two levers Z. Z, the roller M' revolving
between which served to support the clay until the return of the table, when it
slid along the latter just as before.
The way in which the bricks cut are counted has already been sufficiently
described and need not be further referred to.
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:
An automatic brick cutting table and counter constructed substantially as
described with reference to the accompanying drawings.
