invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
Our invention consists in a machine for moulding and dressing stone in a more
efficient manner and at a considerable less cost than can possibly be done by manual
labour and dispensing with rubbing in moulded work as is the usual practice when
stone is dressed by hand and is described as follows together with the accompanying
drawings Figures 1 to 4.
Figure 1 represents plan of machine.
Figure 2 sectional elevation on line A. B.
Figure 3 end elevation.
Figure 4 side elevation.
The letters of reference apply to corresponding parts in all figures.
A is a wooden frame bolted or otherwise securely fastened together, to this frame
are bolted slides B of wrought or cast iron or other suitable metal, C is an iron
tool chest working in slides B and having a number of holes as shewn, in which
are fixed by suitable means the necessary cutting tools for dressing and moulding
the stone to be operated upon.
The cutting tools are made of steel, or iron and steel properly tempered and can
be made of any desired shape to suit the particular shaped moulding required,
either for cornices, copings, architraves, channels etcetera, and by the introduction
of suitable tools, the top and both sides of a stone can be dressed at one operation.
C' shew tools in position for work, of which there may be any number.
D is a stone carriage of solid timber or timbers, travelling on tram rails & and
supported on each side by guide rails d'. Underneath the centre of the carriage is
a rack E running the whole length and geared into the cog wheel E' on shaft F,
supported at either end by pedestals F1 and F': G is a ratchet wheel driven by
eccentric H¹ from main shaft J by pawl connected therewith by connecting bar H:
the ratchet wheel G is for propelling the stone carriage forward as the tool chest
recedes as hereafter explained.
K is part of main shaft J on which are fixed two eccentrics & connected to the
tool chest C for imparting to the same a short reciprocating motion thereby
causing the tools to operate on the stone.
As the tool chest is drawn back by the eccentrics the stone carriage D is
propelled forward ready for receiving contact with the cutting tools by succeeding
forward motion of tool chest. L fly wheel, M and M' fast and loose pullies on
main driving shaft J, N driving belt lever and fork: nn' and n³ are two loose and
one fast pullies on shaft F driven by cross and straight belts direct from primary
motor or from countershaft according to the convenience of circumstances, this
gearing is for running the carriage backwards or forwards quickly when the stone
is not being operated upon.
O is a stop block or buffer made either of iron, or wood iron faced and iron
bound bolted to stone carriage D, against which the end of the stone to be dressed
▲buts.
Qand Q are iron eccentric chocks with projecting square end at top and
projecting round end at bottom fitting into round hole in bed of stone carriage D:

page_text: these are for securely fastening stone to be operated upon in stone carriage, and
are quick in action and most effective.
P is a piece of hardwood moveable at will, and p, p², p², p², p', and p³ battens of
hardwood secured to stone carriage D. The stone to be dressed or moulded is
placed against these battens, the piece of hardwood P placed against the opposite
side and tightened by means of the eccentric chocks Q, Q', and Q' with a spanner:
the clippings from the stone fall into the recesses formed by the battens p, p¹, p³ p³p*,
and p, and removed when necessary.
R and R¹ iron ratchet bars bolted or otherwise secured to each side of the stone
carriage D. SS' to S steel pawls (of which there may be any number) suspended
by cords or chains as shewn, attached to iron rings T and T¹ which are connected
by cords or chains to the set of crank levers U, which are for the purpose of raising
and lowering the pawls: these pawls of which there are two sets, one set to each
side of the machine, fall into ratchet bars R and R¹ and prevent the stone
carriage D from rebounding when the stone being operated upon comes into contact
with the cutting tools by the forward motion of the tool chest C.
The set of crank levers U are also connected by a cord or the like with the
pawl h so as to release the said pawl from the ratchet wheel G which immediately
stops the stone carriage D from travelling forward.
Secured to the bottom of the stone carriage D are two longitudinal slide bars a*
of flat iron which rest upon the rails d, these are kept well greased to overcome
friction.
We do not confine ourselves to any particular size, shape, or materials in the
construction of our invention so long as consistency be retained.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. In a machine as herein described the tool chest C in combination with cutting
tools C or any number of such tools working in slide bars B.
2. In a machine as herein described the side ratchet bars R and R' in combina-
tion with pawls S, S', S³, S³, S*, S, connected by rods or chains to set of crank
levers U.
3. In a machine as herein described the eccentric H¹ in combination with pawl h
and ratchet wheel G.
4. In a machine as herein described the two eccentrics k in combination with the
tool chest C.
5. In a machine as herein described the eccentric chocks Q and the battens
pl på p p p for securing in position the stone to be operated upon.
6. The general form and arrangement of the apparatus and the combination of
the various parts as and for the purposes set forth.
