CARL FRIEDRICH SCHLICKEYSEN, of Berlin, in the Kingdom of Prussia.
"IMPROVEMENTS IN BRICK MOULDING MACHINES."
My Invention relates to an improved brick-moulding machine in which the
pressing cover is lifted or shifted from the press-box by means of a direct movement
of the hand, and it is based upon the application of the said direct movement
of the hand in lifting the said pressing-cover and dropping the same at the proper
times.
The said Invention is illustrated in the accompanying Drawings, shewing
several modifications of my improved machine, like letters indicating the same or
identical parts of the same. I have chosen the said letters of reference in such a
manner as to have each main-part of the machine indicated by a separate letter,
while the underparts belonging to the said main parts are indicated by the same
letter with consecutive.numbers attached thereto.
In the said Drawings
Figure 1 is a side-view partly in vertical section shewing one modification of my
improved machine,
Figure 2 is a transverse section, and
Figure 3 is a plan or top view of the same.
The remaining Figures are hereinafter described.
A is a table-plate arranged on the standards A¹ which are connected by the
cross-piece A, the said table-plate having an inclined arın bifurcated at its upper
end, and carrying the shaft B'. Upon the latter is fastened a star-piece B provided
with the striking-lever B, the weighted lever B³, and the pushing-lever B².
The brick-mould C is screwed upon the fore part of the table-plate A, and is
provided with a movable bottom C³ and a cover C¹ fastened to the striking

page_text: lever B. The small shaft C is journalled in bearings on the cover-plate C₁, and
is provided with two catches C, the fore-one of which has a lever C³ extending in
an upward direction. The said catches C project under another pair of catches
formed on the mould C for the purpose of fastening the cover upon the mould
while the brick is being pressed. Co represents two hanging arms connected with
each other and carrying the said movable bottom C³. The said arms are provided
with the roller C7. D is a double rail moving between the fixed rollers A³ and
having a small catch-lever D' pivoted to its end, which lever can turn in a backward
direction only. The fore part of the rail D is provided with the inclined loop D*,
pivoted at its lower fore-end and made adjustable at its upper end in an upward
and downward direction. The roller C runs in the said loop D'. The bent-
lever D' provided with the weight D5 is pivoted at A5 to the cross-piece A, and
its upper end is held between the pins D, D, and the double rail D, so that it is
compelled to move with the latter; E is a shaft journalled underneath the table-
plate A, and having between the arms C6 a cam E¹ and a lever E², the latter
being connected to the lever E, pivoted at E5 by means of the connecting
piece Es.
In
The operation of the said machine is as follows, that is to say-By raising the
striking lever B the pushing lever B2 is caused to strike the catch-lever D₁ and
move it forward. At the same time the loop D³ lifts the roller C and thereby the
mould bottom C³ is raised above the upper edge of the mould C. The brick
moulded in C is consequently brought to the outside and can be taken off, where--
upon the pushing-lever is pushed entirely over the lever D'. The weight D³
having been raised by the forward movement of D drops down and presses the
rail D back again by means of the pin D. The same effect on the rail D may be
produced by connecting the weight D³ to it by means of a rope and pulley.
consequence of the backward movement of D the roller C runs down again until
the mould-bottom C³ rests on the table-plate A as before. Clay is then inserted
in the mould C and beaten down by the striking-lever B and cover C¹, whereupon
the latter is fastened to the mould by means of the catches C. The lever E' is then
moved down, causing the brick in the mould to receive a pressure from below
after it has been beaten down from above. Finally the cover is unloosened and
the lever B raised to enable the bottom C³ with the moulded brick thereon to be
brought to the outside as above described. If one blow by the lever B* and
cover C should prove to be insufficient and several strokes are necessary, then the
catch-lever Dinust be placed out of action, so that in raising the striking lever
the pushing lever will not move the rail D forward. For this purpose a draw-rod R
is pivoted to the table-plate A (as shewn in Figure 4, hereinafter referred to), the
lower end of which rod is held in a perpendicular position by the weight R² and
connected by means of a light chain R¹ to the lower end of the catch-lever D¹.
The said draw-rod is also provided with a light rod R³ extending, with its handle,
through an aperture in the front portion of the table-plate A, and provided with a
catch R. By drawing the rod R³ to the outside until the catch R' catches behind
the lower edge of the said aperture, the can catch-lever D' assumes an inclined
position so that the moving pushing lever B² cannot touch it. The entire apparatus,
including the lever D', will, by means of the weight R², at once assume its normal
position as soon as the catch R' is set free.
Figure 4 shews in partial side view, and section another modified construction
of my improved machine.
The loop or incline D has in this construction been replaced by a rack D and
pinion D. Part of the said pinion D7 is made with a smooth rim D³ acting as a
cam and carrying the roller C7 with the mould-bottom C. By raising the striking
. lever B the rack D is pushed forward and rotates the said pinion D7, the smooth
part D of the latter thereby lifting the roller C7 until the mould-bottom with the
brick thereon lies free above the mould C. Now when the raising of the lever B*
is continued, the lever D¹ will swing free and the rail D will be pushed back again
by the weight D³ (Figures 1 and 2) descending.

page_text: The pushing lever may in some instances be dispensed with, and the upward
movement of the said striking-lever by means of lever-pressure may be effected in
a direct manner for lifting the mould-bottom and dropping the same, but these are
mere mechanical modifications and combinations of parts readily understood. I
sball therefore only refer to two of such modifications.
In the modification shewa in Figure 5 the hanging arm C is connected rigidly
to an arm C³ extending from the table behind the mould and terminating in a
catch B. The catch-lever D' is fastened to the striking lever B, and in raising
the latter the said lever D¹ carries the catch B3 and the mould-bottom above the
upper edge of the mould. When the brick has been taken off the lever B' is
farther raised slightly, whereupon the catch B₁ slides off the lever D' and then
drops. The mould is now re-filled and the striking lever B' again brought down,
the catch-lever D₁ turning on its pivot, as herein before described, as soon as it
touches the said catch B³.
In the modification shewn in Figure 6 the hanging-arm H is made movable,
being guided near its lower end between two rollers As, and having above the
latter the catch Bs rigidly connected with it. The catch-lever D' is applied to the
hanging-arm C, and the manipulation and operation are the same as described
with reference to Figure 5.
In the modification shewn in Figure 7 a second lever K is applied to the
standard A', the said lever K being connected to the striking-lever B' by means of
a draw-rod H. The catch-lever D is arranged and operated in the same manner
as that shewn in the modification represented in Figure 6. In any of the instances
referred to it is not necessary that the catch-lever shall drop back again into its
normal position by means of its weight, as such movement may also be provided
for by a spring combined with the said lever in any suitable manner. Neither will
it be necessary that the said movement be a turning movement, as in some
instances a sliding movement, as indicated in Figure 12 hereinafter described, may
be applied with advantage.
Figures 8, 9, 10, and 11 illustrate the construction and combination of the
locking-catches with the two faces of the mould.
The said catches consist each of a thin plate M fitting in a taper slot cut in the
said faces, and are tightly held in position by means of pivots N extending from
each face through each plate and holding the latter in its place by means of a pin
or peg. The said plates M are provided with strong rims made of steel, the
horizontal parts of which also serve for holding the toggles or arms C of the cover
during the pressing operation.
A thin plate similar to the plate M may be secured by means of locking-catches,
as shewn in Figure 11. In this instance the said plate on its upper outside portion
carries the locking-catch o, and on its inside has several cross-pieces p, the upper
rim of which has an inclined form, and fits dove-tail-like in a corresponding slot
cut in the outer face of the mould. By means of a small wedge q the whole plate
is then keyed in an upward direction so as to be prevented from falling out. The
Baid plate may be stiffened in any convenient manner, and it is obvious that the
cross-pieces p may be arranged in a different manner to that shewn in Figure 11.
The said cover-plate may enter the mould from about 1% to 3% of an inch, so as
to compress the material in the latter just sufficiently to prevent its escaping from
the mould.
In the modification shewn in Figures 12, 12, 13, 14, 15, 16, and 17, the mould
is laid open by pushing off the cover-plate instead of raising the same, as in the
modifications herein before described. With this modification the pushing movement
is utilized in the same manner as the said lifting movement, that is to say, the
movable bottom is brought out of the mould while the latter is open, and is dropped
again in proper time for re-filling. With this modified form of my improved
machine the operation of beating down the brick is dispensed with, while the mode
of pressing is the same as hereinbefore described. The mould C is provided with two
grooves, within which slide the frame F in a forward and backward direction. The

page_text: said frame F is connected with two standards F¹, wherein is journalled a
cam-shaft F carrying the cam F. Between the said standards the ram or stamper C
slides up and down, enclosing at the same time, the said cam F on both its upper
and lower side, whereby the said stamper C' is caused to follow any movement of
the said cam F.
To the said table-plate is fixed the arm A having a collar for the short spindle F
which is provided on one side with an open slot F³, while on the other side it
carries a fly-wheel or pressing-lever. A square-ended pivot of the cam-shaft F
fits in the said open slot F³. The arm D is fastened to the cross-piece on the
rear-side of the frame F; the said arm extends from under the table-plate A, and
is provided with a projection D. An inclined bar D' is pivoted to one side of the
said projection D, and by its lower end rests upon the arm D, which by means of
two rollers applied thereto is carried by the frame-piece A². To the mould-
bottom C³ is suspended the arm C having a roller C, which is suspended a short
distance above the arm.D. The said roller is touched by the inclined bar D' when
it is pushed or moved underneath the same, so that in pushing the frame F with
the arm D backward, the said inclined bar D will raise the mould bottom C³
until the latter is raised above the upper rim of the mould C. The brick formed
is then taken off the said mould-bottom C³, and the frame F pushed backward a
little further, so that the roller 07 with the hanging arm C and mould-bottom C³
_may_drop_down again, and fresh material be inserted into the said mould C. The
frame F is then pulled forward, the said roller C' passing by the projection-De-and-
raising the inclined bar D', resting loosely upon the arm D, pivoted to the said
projection as hereinbefore described. In pulling forward the frame F the edge of
the cover-plate or stamper C¹ sliding closely across the top of the mould C will
remove all the loam projecting out of the same. When the cover-plate C¹ has
assumed its norinal position above the mould C it is pressed down by turning the
cam-shaft F. The latter is then turned back again and the frame F pushed
backward, as above described. The said cam-shaft may be turned by means of a
lever or fly-wheel, being connected either directly therewith or with its short
slotted spindle Fa journalled in the arm A, ns above stated.
It is obvious that the said cam-shaft F3 may also be applied to the frame A² of
the table, and may be provided with one cam on each outer side of the said frame,
one of these cams is shewn in Figure 16. The cam F is connected with the
pressing-cover or stamper by means of two draw-rods F', the upper ends of which
are bent rectangularly. The said pressing-cover is kept continually in a raised
position by means of springs or weights, and is provided with a cross-piece F³,
projecting laterally from its sides, the projecting ends of which catch under the
rectangular ends of the draw rods F7 in pushing forward the frame F. The
operation of this modification is obvious and need not further be described.
In this modification also the raising of the moulded brick may be effected by
means of a combination of levers and catch-levers, as herein before described,
instead of applying an inclined plane for this purpose; Figure 17 illustrates such
combination of levers, One of the standards A of the frame of the machine is
provided with a projection having pivoted thereto the elbow-lever G, G', the lower
part G' of which is connected to the hanging arm C by means of the connecting
rod H. To the forward end of the bent arm D is suspended a catch-lever D₁
which in pushing backward the frame F with the said arm D secured to the same,
strikes against the lever-arm G and rotates the same until by means of the
lever-arm G connecting rod H and hanging arm C, the pressing or mould bottom
has been raised out of the mould. The operation is then interrupted for a noment,
and the moulded brick is taken off the said bottom, whereupon the frame F and
arm D are pushed backward a little farther in order that the lever-arm G may slide
off the catch-lever D' in consequence of which the parts G, H, C, and the mould-
bottoin connected therewith will again descend. The mould is then re-filled and
the frame F with the arm D again pulled forward, the catch-lever D₁ pivoted to
the arm D sliding across the lever arm G.
