PROVISIONAL SPECIFICATION.
Improvements in the Method of and Apparatus for Carving Wood
and other suitable Material.
I, JOSEPH HELLIWELL, of Well Street, Keighley, in the County of York,
Builder, do hereby declare the nature of this invention to be as follows:-
This invention relates to certain improvements in the method of and apparatus
for carving wood and other suitable material, and has for its object, the con-
struction of the apparatus in such a manner that, whilst preserving all the
advantages of machines constructed as hitherto for the purpose, the operative
mechanism of the apparatus is simplified, less costly in construction and occupies
considerably less floor space.
I accomplish my object in the following manner:-Upon a suitable support, I
mount one or a number of hollow spindles rotated in any suitable manner; and in
the centre hole of each hollow spindle, I mount a centre spindle driven by the first
named spindle and prepared at the end for the reception of a cutting tool.
The centre spindle is prepared for the reception of a spring and the end opposite
to that of the cutting tool projects beyond the hollow spindle.
The before
mentioned spring is so arranged that, by its expansion the centre spindle is forced
backwards, that is to say, in the direction away from the point of the cutting
tool.
The wood or other material to be cut, is fixed opposite the cutting tool or tools
as the case may be, and parallel to the said material, at the other end of the centre
spindle or spindles is mounted the design in relief it is intended to engrave or
carve on the wood or other material.
The rear ends of the centre spindles are kept in contact with the relief pattern
of the design by means of the before mentioned springs, and the wood or other
material to be cut is brought in contact with the cutting tools, which on rotating,
cut away the material to the configuration of the relief design, but in the inverse
direction, the complete design being cut by the rotation of the tools and the
simultaneous movement of the relief design and the material under operation.

COMPLETE SPECIFICATION.
Improvements in the Method of and Apparatus for Carving Wood
and other suitable Material.
I, JOSEPH HELLIWELL, of Well Street, Keighley, in the County of York,
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 :-
This invention relates to certain improvements in the method of and apparatus
for carving wood and other suitable material, and has for its object the construction
of an apparatus in such a manner that, whilst preserving the advantages of machines
constructed as hitherto for the purpose of carving, the mechanism for controlling
the cutters is simplified, acts more direct, less costly and the complete apparatus
occupies little floor space.
In describing my invention in detail, reference is made to the accompanying
drawings, in which
Fig. 1 represents an elevation of a machine suitable for carving wood and the
like in accordance with my method of operating the cutting tools.
D...01

page_text: Fig. 2 is a plan of the same with the top plate removed.
Fig. 3 an end view with plate removed and
Fig. 4 a sectional detail drawn to a larger scale of one of the cutter spindles.
Upon the gantry A is mounted a bed plate B, arranged to reciprocate in the
direction of the double arrows upon the bed A' of gantry A. along with the table C
mounted on the said bed plate. The table C is operated at intervals by the
screw S in the longitudinal direction thereof.
To the standards D is secured a cross plate E having a number of journals
formed therein for the reception of the hollow spindles F driven by belts from the
pulley G, or in any other convenient manner.
Supported by uprights attached to the table C is a plate J, to which is secured
a negative relief pattern H of the design to be carved on the wood or the like
secured to the table C, the pointed end of each centre spindle being held in contact
with the negative design H in the manner as hereinafter described.
The travelling motion to the table C may be obtained in the following manner.
Upon the rotating shaft K is secured a worm L gearing into worm wheel L' keyed
upon a vertical spindle having a cam plate M attached to the top of same and
arranged with a groove M¹ cut in the circumference, with which engages a stud
secured to one arm of lever N, to the other arm of which is attached a rod Q,
coupled to the lever P, having a pawl Q mounted thereto and engaging with
wheel secured on shaft R by a feather key. Upon the said shaft is a bevel
wheel T gearing into bevel wheel T₁ secured on screw S, which is geared with a
nut attached to the table C, so that by the rotation of the cam plate M, the
levers N and P, are operated, and an intermittent rotary motion transmitted to
the shaft R and screw S, by which the table C is caused to slide on the bed
plate B.
The reciprocating motion to the bed plate B and table C in the direction of the
double arrow, is accomplished by means of a cam groove cut on the underside of
the cam plate M, a stud at one end of lever U mounted on a fulcrum engages in
the said groove, the opposite end of the lever being coupled by a rod V to the
underside of the bed plate B, which is thereby operated in a transverse direction
in accordance with the groove on the underside of the cam plate M.
In each hollow spindle F is mounted a. centre spindle F', driven by the hollow
spindle F in such a manner that, it is free to slide therein. The upper portion of
each centre spindle F above the collar W may be formed square or of any suitable
section, and passes through a hole of corresponding section in cap F³, terminating at
the top with a pointed end.
The opposite end of the centre spindles are prepared for the reception of a cutting
tool Y, and upon each spindle is secured a collar W, between which and the bottom
of the hollow spindle is placed a compressed spring S¹, for keeping the pointed end
in contact with the negative pattern of the design to be carved on the wood or the
like.
By the pointed end of each spindle F' being in contact with the negative
design H secured to the plate J, and the design moving over the ends of each
spindle in a transverse and longitudinal direction, the respective centre spindles F
slide in the direction of their axis in accordance with the design H on plate J, and
thereby cause the centre spindles F and cutting tools Y attached thereto to
protrude, retreat and cut away the wood or the like fixed on the table C, to the
configuration of the said design but in the inverse direction.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. In a carving machine the mounting of one or more rotating spindles Fin
suitable bearings in a manner that one end of cach centre spindle is kept in
contact with the negative design H substantially in the manner and for the purpose
as hereinbefore set forth.

page_text: 2. In a carving machine a centre spindle F¹ having a collar W and spring S¹
enclosed in the hollow portion of spindle S, combined with a design H and movable
table C, for the purpose as herein before set forth.
