PROVISIONAL SPECIFICATION left by the said Charles Louis Lapito
at the Office of the Commissioners of Patents, with his Petition, on the
6th September 1856.
I, CHARLES LOUIS LAPITO, of No. 75, Foubourg Poissonier, Paris, at present
residing at No. 2, High Street, Marylebone, Manufacturer of Mortar and
Concrete, do hereby declare the nature of the said Invention for "A MACHINE
FOR MANUFACTURING OF MORTAR AND CONCRETE," to be as follows:-
This machine is moveable on an inclined plane, in which is a rolling sphere,
into which the matter is introduced, either of mortar or concrete, to procure a
mixture of the one or the other. The basis of this machine consists of an octa-
gonal scale of wood (see Figs. 1 and 3), placed upon metal rollers, disposed in
such a manner as to be able to make an instantaneous removal of the machine
as the service requires. On the scale is established an inclined plane (see
Fig. 3), constructed of metal, and turning on axle in the centre of the frame;
this plane is put in motion by a pinion adapted to a cog wheel disposed according

page_text: to (Figs. 2, 3, and 4.) The inclined plane is supported on rollers of metal,
on which they move in perfect order; the top of the plane is formed of rails
by two octagonal yokes, forming together, by their disposition, a mixing receiver,
in which the sphere rolls in order to produce a blending of the matter.
The Fig. 5 demonstrates the disposition of the said receiver.
Finally, the sphere and its accessories and armed ball (see Fig. 6) and all
its dependancies, form a machine to make the mortar and concrete to per-
fection.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Charles Louis Lapito in the Great Seal Patent Office on
the 23rd February 1857.

or administrators, by an instrument in writing under my, or their, or one of
their hands and seals, should particularly describe and ascertain the nature
of the said Invention, and in what manner the same was to be performed,
and cause the same to be filed in the Great Seal Patent Office within six
calendar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said Charles Louis Lapito, do hereby
declare the nature of my said Invention, and in what manner the same is

page_text: to be performed, to be particularly described and ascertained in and by the
following statement:-
My Invention consists of a machine for manufacturing of mortar and con-
crete in a complete manner, of reducing hard bodies and dry granes into
powder. However, my principal idea is to apply my machine to hydraulic
works which are in need of mortar and concrete. 1st, the mortar, by mixing
lime and sand together; second, concrete, by mixing mortar and stones; third,
concrete, by mixing lime, sand, and stones together at the same time.
The utility of this machine has for object the making of ports, bridges,
docks, canals, locks, sewers, railways, manufactories, houses made and built of
concrete, footpaths, highways or public roads, and all such works.
The groundwork of this machine is composed of eight wooden spokes united
in the centre, being each of them one meter fifty centimeters in length, and
representing an octagonal form. Under the eight spokes is a railway, under
which are placed metal rollers, which render the whole moveable; in the
centre of this octagonal plan or ground work is fixed, on the eight spokes by
the means of eight metal pins, a patin of metal taking the inclination or bend-
ing of the machine, and upon which patin is placed a rolling metal corbeille or
basket being of an octagonal form, and being of the same diameter as the
plan. This corbeille forms at its extremity a through, in which is the sphere
which mixes together the different materials; this corbeille or basket is sup-
ported in the center by a crown or cogged wheel of one meter in diameter, and
to which is adapted a pinion of the same metal pierced through by an horizontal
tree, which is fixed to it on the one side, and on the other side to winch, which
is put in motion either by men, horses, or steam power. This crown or cogged
wheel, to which is firmly fastened the corbeille or basket, is gone through in the
center by a vertical tree or axis, and by its means the machine is to be put in
motion; in the center of the through is an octagonal railway, upon which the
sphere continually rolls when the sphere makes the trituration of the different
materials. This railway of an octagonal form rolls on eleven cylinders placed
on eight pins forked, being each of them of a length in proportion to the
inclination or bending of the machine; upon two of the eight exterior sides of
the railings is made an opening, which is shut up at will by means of a metal
bar, with hinges to it, in order to let out or let in the spheres.-See the
Drawings.
For the service of the service machine, four or five spheres, having each of
them a lid, with which they are hermetically shut, and at the same time an
opening to allow the materials to be put into them or taken out after tritura-

page_text: tion; these four or five spheres go in and out of the machine in succession
when the machine is in motion.
For the manufacturing of mortar alone, there is a metal bomb set thick with
strong metal nails put into each sphere to aid in the making of its mixture.
-See Figure 8 in the Drawings.
To reduce to powder hard bodies and dry granes, there is a ball also put
into each sphere, but without the nails.-See Figure 9.
The Specification in all its particulars of the present machine.-The
principal basis of the machine, or its groundwork, is of oak timber work,
and is composed of eight pieces or spokes, each being in length one meter
fifty centimeters, and from twelve to sixteen centimeters square; these eight
spokes in oak have, at each end of them, and one in the center, nine metal
rollers five centimeters thick, and in their diameter twelve centimeters, placed
in a box of the same metal, and placed under and fixed to the scale by metal
screws. In the center of the scale, and on the superior surface, is fixed by
means eight metal pins, which go through the timber work, a metal patin or
sort of horse-shoe, circular in its inferior and superior parts, and having four
metal bars which serve to strengthen it; this patin is inclined according to the
slope of the machine, and is bored through the center with a hole six centi-
meters in diameter, in which is placed the pivot or axis which serves to turn
the machine. This patin is about thirty centimeters in length, its base fifty
centimeters in diameter, and its superior part about twelve centimeters in
diameter in the circumference of the patin, and on the superficies of the
wooden spokes is a large circle of two meters in diameter, five centimeters in
width, and two centimeters thick. This metal circle binds the one to the
other the wooden spokes, in which there are holes as well as in the circle, which
are destined to receive the eight pins forked; these metal pins have a basis
placed in the bored circle as well as the spokes bored, are fastened by metal
nuts.
These pins are, each of them, four centimeters in diameter, and are placed
at equal distance on the metal circle. All these pins are of unequal length,
according to the bent of the machine. The superior part forms a forked
square, to receive the cylinders in metal, which are twelve centimeters long,
and six centimeters in diameter. This plate forms the first Figure in the
Drawings.
In the fork of the four pins (see Figure 3) of the shorter dimension, are
lodged two circles, placed at twelve centimeters the one from the other, being
each one centimeter in thickness, by four centimeters in width. These two

page_text: circles are pierced through by three pins, which receives also the cylinders of
the same dimension as the others. The crown, which is placed on the patin
inclined, is of one meter in diameter, composed of eight branches, with
at the end of which branches is fixed the cylindrical circle, furnished with
coggs to receive a pinion; at the extremity of the eight branches, and at the
exterior part of the circle are ears, half circular, bored through to receive a
metal pin. The center of the crown is a full circle of twenty-five centimeters
in diameter, and ten in thickness, to which the eight spokes are made fast.
The center of the crown is gone through by a pivot forty centimeters in length
by six in diameter, which descends to the bottom of the patin. On each branch
of the crown is placed a metalic spoke of two centimeters in thickness and three
in width, and each of them one meter forty centimeters in length. These eight
spokes are fixed in the one end to the circle of the crown, in the center to the
ear of the crown, by means of a metal pin, and at the other end to an eye, to
receive an inclined railing, at a meter from the centre of the crown; and under
each of the spokes, and all of them, passes metal railway of an octagonal form,
and fixed to the spokes by means of screws. It is on this railway the sphere
runs which makes the trituration.
On each of the eight metal spokes are placed two metal bars of two centi-
meters in thickness, by three in width, fastened to the spokes by screws; these
two metal bars are placed vertically, but each of them inclining in a different
direction, and forming a sort of trough. The bars, which are placed near the
crown, are about fifteen centimeters in length, and have in their extremity a
fork, placed in such a manner as to receive an octagonal barrier. This barrier
is about three meters in circumference, and two centimeters in diameter; the
bars placed in the extremity are about thirty-five centimeters in length, being
two centimeters thick, three in width; at the extremity of which are holes, in
which holes passes an octagonal barrier, seven meters fifty centimeters in
circumference, and three centimeters in diameter. Two of the eight sides of
this barrier form an aperture, which shuts and opens by means of a hinged
metal bar on one side, and on the other by a notch, being three centimeters in
diameter; it is through these two apertures that the spheres are brought in
and out.
On the right side of the machine (see Figure 5), and in the fourth part of
its inferior circumference, passes a metal barrier of four centimeters in
diameter, and about two meters long, fixed on the one end to the pivot, and
passes over the barrier, and is placed at the other end to one of the spokes,
which forms the groundwork; this barrier is destined to let down again the
sphere.

page_text: (The Figures 6 and 7).-The spheres for the service of each machine are
four or five, according to the cleverness of the workmen; they are seventy
centimeters in diameter, and the metal of which they are made are three
millimeters thick. On one of the parts of the sphere is a circular aperture,
forty-five centimeters in diameter, which serves to put in the materials or take
them out; this aperture has a groove one centimeter in width, and three
millimeters in depth, to receive the lid of the sphere. This lid is maintained
in the groove by means of four pieces of metal, each twenty-five centimeters
long, three millimeters thick, and four centimeters wide; they exceed the
borders of the lid by seven or eight centimeters. On one of the sides of these
pieces of metal, which exceed the borders of the lid, is a notch, of one centi-
meter in depth, in which is placed a round-headed pin, which is fixed to the
principal body of the sphere, at equal distance, to enter into the notches made
in the ears of the lid. The shutting is performed by two handles, which are on
the lid, handled by a workman. The bomb, which is put into the sphere to
aid in the trituration of the mortar, is thirty centimeters in diameter, and the
metal of which it is made one centimeter thick; the spikes are placed all
round the bomb at four centimeters the one from the other, and are projecting
out of the bomb four centimeters. Each of the spikes are eight millimeters in
diameter, and are fixed to and in bomb by means of holes, made for that
purpose (see Figure 8).
To reduce hard bodies and dry granes to powder, we use a metal ball, but
without the spikes (see Figure 9). The machine and its accessories may be
made to any size, according to the power we wish to employ.
The wooden horse which receives the spheres is made of two oak or wooden
pieces, each three meters long, and from eight to twelve centimeters square,
separated one from the other at the distance of twenty centimeters, and united
at their extremities by two other pieces of wood of the same force. This horse
is supported by four feet, of the same force, each twenty-five centimeters in
length. At the two-third part of the body of this horse is a small wooden
platform, one meter long, eighty centimeters wide, and six centimeters thick,
united at the two ends by wooden pieces crossing, eighty centimeters long, ten
wide, and six thick, placed on one end on one of the wooden spokes of the
machine, and on the other in a groove made in one of the sides of the wooden
horse. At one of the ends of the horse, the right hand of the machine is
adapted to the two sides of the horse. A metal circle, fifty centimeters in
diameter, two centimeters thick, and five centimeters in width, is fixed to the
horse by two pins, which goes through it; these pins are forty centimeters
long, two centimeters in diameter, and have, at the one end, a metal screw,
and the other a head.

Figure 4 represents the crown, its pinion and swivel, by which the machine
is turned, taken on the line A, B.
Modifications are proposed in the accessories of the machine, as well as to
rectify what has been involuntarily forgotten; they are, 1st, to replace the
double wooden horse by a single one; second, to form a curved line at each
spoke of the basket in the place of a strait line; third to put or be put a
ball, which is to reduce hard bodies and dry granes to powder.-See the Plan.
In witness whereof, I, the said Charles Louis Lapito, have hereunto
set my hand and seal, this Twenty-third day of February, in the year
of our Lord One thousand eight hundred and fifty-seven.
