Improvements in Stamping or Beating Machines for Moulding
Artificial Stones and the like.
A communication from abroad by JOSEPH WINKLER, of Kiesenbach, in the Empire of
Gormany, Machine Manufacturer.
1, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of the Agency for Foreign
Patent Solicitors, 6, Lord Street, Liverpool, and 6, Bank Street, Manchester, both in
the County of Lancaster, and 323, High Holborn, in the County of Middlesex, Civil
Engineer, do hereby declare the nature of this invention to be as follows:-
The invention relates chiefly to stamping or beating machines particularly designed
for moulding artificial stones."
In the present machine, the to and fro shifting motion of the filling box is effected
by a lever having two arms turning on a point situated under the main shaft. The
lower end of this lever shifts the box to and fro by means of a connecting rod, this
alternate motion is effected through the upper end of the lever which is provided with
double arms.
A crank pin fixed on a disc of the main shaft, enters into engagement
with this double ended lever in such a manner, that when the disc and crank pin are in
one position, the filling box stands outside the line of the falling ram, but when the
disc is turned on its axis the box is moved so as to stand with its fore end under the
ram.
Two wings, which are fixed to the hammer and carry a roller having its bearings
therein, are placed in such a position that the hammer can be raised without stopping
the machine; this is of great importance for the attendants, and it also facilitates
cleaning. The weight of the hammer in the experimental machine is about 450 kilo-
grams. The hammer presents at the back and between the wings, a circular recess
provided to prevent the revolving tappet wheel (which raises the hammer) from
striking the hammer when it is raised. On the front part of the hammer there is a
heel, which forms a support on which the hammer rests when the machine is being
cleaned, etcetera. The tappet wheel has four tappets, by means of which 4 blows to
027

page_text: each revolution are given to the stone. These tappets are made different lengths so
that the hammer is raised successively to a higher position than the last. In the
model machine it falls successively 22, 27, 33 and 38 centimetres. On the first blow
the air is driven away partly out of the material, and completely after the second,
third, and fourth blows. The stones submitted to the treatment of the machine are so
solid that they fulfil all the conditions that can be expected of them, and the machine
may be considered to supply a good average material. Whilst the hammer rests on
the sloped parts of one of the tappets, the filling box moves forward to fill up the
mould, and to push away the stone which has been finished previously in the same
mould. At the same time the anvil remains also raised by means of a tappet or arm
on the main shaft, which engages a lever, and actuates said anvil by means of a pull
rod. This lever has its axis on the driving shaft, and 2 blows are given on the
filling box, so as to feed material to the mould. When the tappet on the opposite
side of the tappet wheel, comes in contact, the filling box is withdrawn, and the
hammer raised and cleaned.
The filling hopper is raised, and stands vertically over the filling box; the filling in
is thereby rendered easier. The filling hopper can be made to store up the material
necessary for making from 6 to 10 stones.
The throwing out of gear or lifting of the hammer for cleaning, etcetera, is effected
by disengaging gear, consisting of a shaft, having a lever catch and eccentric.
By pulling a lever, or pressing down on the aforesaid lever, the catch is pressed
under the heel, the hammer having reached its top position will then be raised again
a little by an eccentric lever, so that the tappets on the tappet wheel will clear the
striking roller on the hammer, this being easily effected by a lever. The turning of
this lever effects a safe fixing of the hammer, so that the latter cannot fall upon one
of the tappets that may happen to be under it, or on the filling box, at any improper
time..
A bolt serves as a guide to the anvil, when it stands at the same height as the
moulding box. The disc may be provided with a friction roller for the purpose of
diminishing the friction on the levers.

page_text: I, WILLIAM PHILLIPS THOMPSON of 6 Lord Street, Liverpool, in the County of
Lancaster, and 323 High Holborn in the County of Middlesex Civil 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 machine which forms the subject to this invention is designed to make in an
expeditious manner bricks, briquettes or cakes of cement, slag, black-lime, coal-dust or
other suitable material, and to automatically carry out all the necessary operations for
this purpose, such as conveying the materal to the moulding-box, introducing it into
the same and stamping or pressing it, then lifting the finished brick or cake from the
said box and pushing it away.
In the accompanying drawings,
Figure 1 shows a sectional side view of the machine.
Figure 2 a front view, and
Figure 3 an upper view of the same.
The principal operations of the machine are as follows, viz.
Below the funnel or hopper O is arranged a feed-box G which is open above and
below and is adapted to be moved to and fro, for the purpose of receiving the fresh
material, and conveying the same below the hammer P, in which position the feed
box allows the material to drop into the box G' in which it is moulded into the form
of bricks or cakes. The sole or bottom of this box is formed by an anvil J which can
be raised by suitable means.
The mechanism for lifting the drop-hammer P is so arranged that the latter will
strike several blows of gradually increasing power upon the material, in order to form
the brick or cake, and that in the progression and retrogression of the feed-box G the
hammer P will be kept raised sufficiently high to allow the passage of the same below
it. By arranging a scraper N on the front side of the feed box G, the under surface
of the hammer can be kept clean, the said scraper N cleaning the bottom of the
hammer in every to-and-fro movement of the said box.
Another mechanism lifts the bricks or cakes from the moulding-box, and devices
are provided for keeping the drop-hammer raised.
The improved machine is set in operation through the medium of fast and loose
pulleys A A' or equivalent means arranged upon the shaft a. Upon this shaft is
placed the pinion B which engages with the spur-wheel (on the shaft b. The latter

page_text: shaft carries two dises having each a pin 2. The pins 2 act upon the two-armed
levers whose fulcrum is below the main shafts
a; bat i, and whose lower ends
impart the reciprocating movement to the feed-box G by means of the rod E'.
In order to effect this movement the pins 62 on the aforesaid discs & engage with
the ends E and E3 of the levers E and cause the latter to perform one oscillation in
every revolution of the shaft b.
In Figure 1 the pin 2 is shown in two opposite positions.
A disc-cain D is arranged upon the shaft and carries four projections F, F¹, F², F³
of differing lengths, by which the drop-hammer P is successively raised higher and
higher so that every following blow of the same will be stronger than the one that
has preceded it as the said projections strike against a friction roller held between
two brackets e on the drop-hammer.
In Figure 1 are shown four positions f³,ƒ³, f³, f
The disc cam is provided with two steps,
which are of such a height that when
the friction-roller is raised by one of the said steps the drop-hammer will be high
enough for the feed-box G to pass beneath it.
One of these steps coincides with F.
Two arms TT, Figure 3, secured upon the shaft b, have surfaces by means of
which the levers L L are raised. The latter are connected with the movable anvil J
through the medium of rods K K¹ so that in the upward movement of the said levers
the finished brick or cake upon the said anvil will be raised to the level of the
table M.
While the drop-hammer is raised by the surface F, the feed-box G moves below
the hammer, pushes back the finished brick or cake, and passes above the anvil J,
whereupon the latter is caused to descend. The drop-hammer then strikes two blows
through the fed-box upon the material so that this box will be empty when the hammer
is kept raised by the surface a.
In this position of the hammer the feed box G is moved back to be filled
again.
The projections F2 and F3 will then cause the drop-hammer to give two more blows
upon the material in the moulding box to finish the brick or cake.
In order to enable the drop-hammer to be kept raised, the shaft is provided with
an excentric to which is connected a lever,. Upon the excentricis arranged a
ring connected with a lever g and provided with a stop piece q. By pulling the lever
to the perpendicular position the stop piece is moved below the projection e² on the
drop-hammer when it has been lifted by the longest projection F³. To prevent contact
with the drop-hammer in the further rotations of the disc-cam, the pawl or pro-
jection is raised a little further by turning the excentric ¹ by means of the lever ³,
as shown detached in Fig. 1*.
Having now particularly described and ascertained the nature of the said invention
and in what manner the same is to be performed as communicated to me by
my foreign correspondent 1 declare that what I claim is :-
First A machine for moulding cement and other materials into the form of
bricks, cakes and the like, which machine comprises the drop-hammer P adapted to be
raised by projections F F F F on a rotary disc-cam D, the anvil J which is raised
and lowered by means of draw-rods K, levers L and arms T, the feed box G for
conveying the material to the moulding-box and pushing away the finished bricks,
cakes or blocks, the said box being actuated by means of levers E which are, pivoted
at i and have forked arms E2 E3 acted upon by pins or friction-rollers 62 on discs fixed
upon the shaft b.
Second In the machine characterized in the first claiming clause, the arrangement
which enables the drop-hammer P to give several blows of gradually increasing
power by means of the cams F F1 F2 F3 which progressively increase in length,
furthermore the arrangement which, in virtue of the concentric surfaces a, a¹, enables
the said hammer to be kept for some time at an equal height, in order to allow
the feed box to pass below.

page_text: Third For arresting the drop-hammer, the lever and pawl mechanism q q' in
combination with the lever and eccentric ¹ whereby the drop-hammer can be raised
a little higher in order to move it out of the path of the projections on the disc
cam.
Fourth-The arrangement on the feed-box G, of a scraper N so that in the return
movement of the said feed-box it will clean the under surface of the drop-
hammer.
