EDWIN CHATHAM Builder Church Street Rhosymedre Ruabon do hereby declare the
nature of this invention to be as follows:-
My invention consists of a trough, which may be called a cradle, preferably oblong
in shape and bent at each end so as to form a part or segment of a circle, into which
a roller will be put which, being loose and free will roll from one end to the other of
the trough when it is being rocked (cradle fashion). In making and grinding mortar
the lime sand and water will be put into the trough, and then mixed and ground
together by means of a man or men rocking the trough or cradle so as to set the roller
in motion, which will roll from one end to the other. The roller may be flat at the
sides with a square, round or beveled edge or, it may be a round ball, in either case
the bottom of the trough will have to corrispond so as to secure crushing or grinding
surface, the sides of the trough to be beveled so that every thing put into the trough
will find its way down to the bottom and then under the roller, in the case of flat sided
rollers being used guide rods may be fixed inside the trough from end to end to keep
the roller on its edge and in position to get the mortar out a hole with a spout will
be at the bottom of the side which can be opened and closed by means of a slide or
door and in order to get as much power as possible to rock the apperatus a pole or long
handle can be fixed at one or each end of the trough or cradle-rails or upright
guides will probably be used as a means for keeping the apparatus in position when
being rocked- -can be made of steel or irou, or steel iron and timber combined.

A New or Improved Apparatus for Crushing and Mixing Mortar.
I, EDWIN CHATHAM of Church Street Rhosymedre, Ruabon Builder, 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 and
accompanying drawings:
This invention relates to Mortar Mills or apparatus, or machinery for the purpose of
mixing and crushing mortar of lime and sand or other materials for use in Building,
engineering or other operations whatsoever, that require the use of such mortars for
their proper execution; And the said invention consists of a long and narrow Box or
Cradle open at the top, placed on rockers so that it can be rocked from end to end
after the manner of an ordinary rocking chair; In the said Box or Cradle is placed a
roller either cylindrical or spherical in form, which is capable of being rolled
backwards and forwards in the aforesaid box or cradle, and thus effectually mixing
and compounding the mortar or other material or materials it is desired to unite or
assimilate.
The detail of the construction of the above-mentioned new Mortar Mill is as
follows:-
The Box or Cradle as aforesaid is constructed, to any required dimensions of iron
or other suitable material, and it may be either straight or segmental in elevation, and
rectangular or otherwise in section, according to the form of the roller aforesaid it is
desired to employ. The said Box or Cradle is to be fitted with handles at both of its
ends much after the position of the handles of an ordinary wheel-barrow.
The said Box or Cradle is secured, by means of flanged chairs or brackets fastened
to its sides, to the Rockers aforesaid which may be composed of Lor T iron or other
suitable section; these Rockers should not be immediately underneath the said box, or
cradle but should overlap it which is provided for by the projection of the flanged
chairs, or Brackets aforesaid; this arrangement diminishing the chance of the
apparatus being accidentally overturned.
The said Rockers may rest directly on the ground, or preferably on a pair of iron
rails of any suitable section laid longitudinally, or the mill may be rocked by means
of a pivot fixed under the centre transversily, in which case a spring would be fixed at
each end of the box or Cradle acting on the ground to facilitate the operation of the
mill.
In the Box or Cradle aforesaid is placed the Roller as mentioned above, composed
of iron or other heavey material, this Roller should not be the full width of the Box or
Cradle, and to ensure its running to and fro evenly it is to be constructed with a
projecting portion on either side; which shall nearly touch each side of the said Box
or Cradle when the Mill is at rest, and which will act as guides when the mill is at
work. This new Mortar Mill is put in operation by alternately elevating and
depressing each of its ends, causing the said Box or Cradle to rock from end to end
when the said roller will roll to and fro the whole length of the Box or Cradle, and
thus thoroughly crushing and compounding the mortar or other material or materials
placed in the said Mill for that purpose.

page_text: In order that the nature of my said improvements may be the more fully understood,
I will now proceed to describe the several figures on the sheet of drawings hereunto
annexed, all of which figures are marked with the like letters of reference throughout.
Figure 1. is a side elevation of the new Mortar Mill.
Figure 2. is a plan of the same, and
Figure 3. is a transverse section; and the corresponding letters on all three Figures
relate to the same parts of the Mill they distinguish in each.
A is the box or cradle, B, B, are the handles to the same, CC are the flanged chairs
or Brackets, and DD are the Rockers, EE are the rails on which the said rockers
work, and F is the roller which traverses the length of the said box or cradle, and
which is constructed with projecting portions G, G.
Having now fully described and ascertained the nature of my said invention and
in what manner the same is to be performed, I declare that what I claim is.
The combination of a Box or Cradle capable of being rocked by reason of its own
form or by means of Rockers attached to its under side, and a Roller placed inside
the said Box or Cradle capable of running from end to end of the said Box or Cradle
and thus effectually performing the office of a Mortar Mill.
