My improvements consist in a hopper automatically agitated to facilitate the
passage of the clay under a stamp, the hopper being used in connection with a
mold board and stamp moving intermittently; in providing a stamp automatically
operated and working in the hopper for the purpose of feeding the clay to the
molds; in providing one or more pressure plates with holes or vents to permit
the escape of air and surplus clay from the molds; in devices for applying coloring
matter or enamel to the upper surface or edge of the brick; and in devices for
removing the pressed brick from the machine, and at the same time applying
coloring-matter or enamel to the upper surface of each plunger, which presses the
brick from below for the purpose of applying coloring-matter to the lower side or
edge of the brick.

B. is a spur-wheel and mold table, provided with a series of mold boxes C.
D is a mutilated spur pinion meshing into the spur-wheel B. D is mounted
upon an upright shaft E, which is driven by mitre gears a. b.
Ench mold-box is provided with a piston or follower F, each of which is secured
to a vertical stem G, and each stem passes through an opening in the mold table.

These stems G are provided with friction rollers at their lower ends.
boxes C can be cast, and, as shown, are provided with flanges c, by which they are
bolted to the mold table.
d are pieces of metal, bolted one to the outer end of each mold box; and each
piece d is provided with a recess e, to receive the detent f, and which is operated
by means of the cam H, upon the shaft E, there being a cam groove g in the upper
surface of H, into which grooves the pin / extends out from the detent f.
i is a casting secured to the uprights I. In one part of this casting i there is a
bearing for the shaft E, and the detent ƒ passes through and is supported in this
part as shown in Fig. 3.
J are pressure plates secured to the cross pieces J' of the frame, which are
secured to the posts K, except that one end of one piece is secured to i. As shown
there are eight mold-boxes, three only of which are at the same time covered by
the plates J.

holes through one of the pressure plates J, and through the part J'
As the mold table rotates the lower ends of the stems G, travel over bearing
pieces j, cam yokes k, and inclines 7, 1, and the pistons or followers are forced up
by the action of cams or shafts beneath said yokes k, and by the passage of the
lower ends of the stems over the incline l.
L is a case supported in any suitable manner over the mold-table, so that the
mold-boxes may pass directly under the case. M is a hopper located in the case L,
and arranged so that it can have a little lateral movement therein. As shown
the hopper is provided with a projecting piece m on each .end, which pieces
enter grooves in the opposite sides of the case L, the hopper being a little narrower
than the case.
n is a strong pin or projection permanently secured to the hopper M, and
passing through a slot in the side of the case L.
This pin is turned down a little at its outer end and engages with a series of
teeth or projections provided upon the outer edge of the mold-table.
A is a spring adapted to move the hopper in one direction.
N is a stamp or plunger in the hopper M, which is secured to the lower
end of a frame O, which moves up and down in guideways o as shown in
Figure 1.
p is an arm or lever pivoted in the frame O. To the upper end of p is pivoted
one end of one arm of a bell-crank lever P, which lever is pivoted to a suitable
support; to the lower end of the other arm of the bell crank lever is connected
one end of a rod ; the other end of this rod is pivoted to an arm as hereinafter
more fully set forth.
Qis a box resting on a suitable support 8, on a level with the top of the mold-
boxes, and adapted to be moved outwards over the mold-boxes and drawn back
again. The bottom of this box Q is perforated.
R. is another box similar to Q, having a perforated bottom arranged upon a
suitable support, on a line with the top of the mold-boxes, and adapted to be
moved outwards and drawn back again.
S is a bevelled gear-wheel at the end of the main shaft T; which bevelled
wheel engages with the two mitre-wheels U. V.
t is a small mutilated bevel-wheel, connected with the bevel-wheel S, and
engaging with the bevelled gear-wheel u, upon the lower end of the shaft W.
To the upper end of this shaft W is rigidly secured an arm v, to the outer end of
which is secured a pin a¹.
6 is an arm one end of which is pivoted to the pin a', and the other end is
pivoted to the side of the box Q.
c is another arm, the outer end of which is pivoted upon the pin a¹, the other
end, as shown, is provided with an upward projection, to which one end of the
rodris pivoted.

end is pivoted to one end of an arm or rod e¹ the other end of which is pivoted
to the box R.
As shown in the Drawings the pinion D is supposed to make eight revolutions,
while the revolving table B makes one revolution, and the pinion D being.
mutilated the table B moves intermittently. The shaft W also makes eight
revolutions while the table B makes one.
The wheels u. t, are provided with the same number of cogs, but t being
mutilated W stands still a portion of the time.
The arrangement and construction of the parts is such that the shaft W stands
still while the table B moves, but rotates while the table stands still. The bevel-
wheel t may be secured directly to the shaft T.
The metal pieces d on the outer ends of the molds need not be used, and the
outer end of each mold may be provided with a recess to receive the detent f.
The operation is as follows:-Clay is fed to the molds through the hopper,
which will be agitated by the devices described, which will facilitate the passage
of the clay beneath the stamp O, and the stamp being carried downwards while
the table B stands still, clay will be forced by the stamp into the molds.
The stamp N is operated by the rotation of the shaft W through the arm v,
pin a' arm c¹ rod lever P. and arm p. The table will then move until the filled
box passes beneath the first pressure plate, where it will stop and the piston or
follower F, will be forced upwards in its mold, by the yoke and cam-shaft beneath,
and the air and any surplus clay in the mold can escape through the openings w.
While this is being done, an empty mold will be filled.
The table B continuing to rotate the molds will be brought one after another
under the next pressure plate, and additional pressure will be applied by the yoke
and the cam-shaft beneath.
When each mold is brought in line with the box Q the table will rest, but the
shaft W rotating will, through the arm b', cause the box Q to move towards the
periphery of the table B, passing over the mold at that point, and the box being
supplied with coloring-material or enamelling material, a portion of it will be
distributed through the perforations in the bottom of the box, over the surface of
the clay in the mold. When each mold reaches the point opposite to the letter B',
Figure 1, the piston in the mold will be forced up, bringing its top on a level with
the table, and then by the rotation of the shaft W, the box R, will be forced
outwards towards the periphery of the table by means of the arms d, e, and this
box being supplied with coloring or enamelling material, a portion of such material
will be deposited upon the surface of the piston or follower F; and such coloring
material will be applied to the under surface of the next brick formed in such
mold, so that, by the means described coloring or enamelling material can be
applied both to the lower and upper surface of the brick.
The rotation of the shaft W operates the stamp O, moving it both down and up
and also at the proper time pushes out and draws back the two boxes Q and R.
If it be desired to apply coloring material or enamelling material to the two
edges of the brick, instead of the upper and lower surfaces thereof, this can be
done by changing the form of the molds, placing them on edge.
I use moist clay of such consistency and condition that the agitation of the
hopper will partially, at least, fill the molds, and the stamp forces clay into the
molds partially packing it therein, it being the intention to always supply a small
surplus to each mold, hence it becomes essential to provide for the escape of the
surplus so that the proper quantity of clay will remain in each mold.
A travelling belt may be provided to receive the completed brick from the
mold-table.
I apply coloring or enamelling matter to the upper surface or edge of the brick
before the final pressure is applied, so that such matter may be pressed firmly into
or upon the face of the brick.
