Improvements in Wood Working Machines for Moulding Balusters
and the like.
We, JOSEPH HENRY OLLIER, of 66, Clifford Street, Chorlton Road, Manchester,
in the County of Lancaster, Wood Cutting Machinist, and WILLIAM BROWN, of
Mount Vernon, Eccles New Road, Pendleton, in the said County, Builder, do
hereby declare the nature of this invention to be as follows:-
Our invention relates to improvements in wood working machines for moulding
balusters and other articles to square, octagonal and other forms in cross section,
or partly of one shape and partly of another shape or shapes.
In carrying our improvements into effect we employ a suitable frame to carry
an adjustable bed plate on which we fit a carriage in slideways so that it can be
moved to and fro as required. The carriage is provided with clamps for securing
in position the squared spindle or piece of wood to be moulded and with adjustable
centre bits or guides for adjusting the squared spindle relatively to the cutters.
We employ a rotating cutter block or two or more of such cutter blocks preferably
two, to which we secure the cutters and which are driven by any convenient
means. The carriage with the squared spindle is traversed over the first rotating
cutter block the cutters on which mould one side then the carriage is moved
back, the squared spindle is turned and the carriage again traversed over the
first rotating cutter block to mould the next side the operations being continued
and repeated as described until all four sides have been moulded.
When it is desired to mould the baluster or other article octagonally, hexagonally
or of any other section than square we clamp one corner of the squared spindle
in a groove in a suitably prepared pad attached to the sliding carriage which
is then moved forward to and passed over a suitable rotating cutter block and by
adjusting the spindle in the pad and traversing the carriage over the cutter
block as often as necessary the baluster is moulded to the desired section.
It is obvious that the baluster may be moulded throughout of the same section
or partly of one form and partly of another section or sections and that when
required several rotating cutter blocks may be employed to obtain the desired
variations of form.
The cutters which we employ are V shaped or variations of the V formed by
say omitting one side or blade or removing a part or parts of the metal at the
point of the V or else where according to the form required.
These cutters are formed with or fixed on shanks which are bolted to the rotating
cutter block and the form and set of their cutting edges insures a lead' that is to
say the blade meets the wood diagonally and so comes gradually into action thereby
cutting the wood without tearing it.
When moulding long or delicate spindles we may arrange the cutters on the
cutter blocks so that the first cutters remove a portion of the width of the squared

page_text: spindle and the cutters on the succeeding block or blocks remove the remainder and
thus the piece of timber is not liable to spring and be torn.

Improvements in Wood Working Machines for Moulding Balusters
and the like.
We, JOSEPH HENRY OLLIER, of 66, Clifford Street, Chorlton Road, Manchester,
in the County of Lancaster, Wood Cutting Machinist, and WILLIAM BROWN, of
Mount Vernon, Eccles New Road, Pendleton, in the said County, 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;
Our invention relates to improvements in wood working machines for moulding
balusters and other articles to square, octagonal and other forms in cross section,
or partly of one shape and partly of another shape or shapes.
In carrying our improvements into effect we employ a suitable frame to carry
an adjustable bed plate on which we fit a carriage in slideways so that it can be
moved to and fro as required. The carriage is provided with clamps for securing
in position the squared spindle or piece of wood to be moulded and with adjust-
able centre bits or guides for adjusting the squared spindle relatively to the
cutters. We employ a rotating cutter block or two or more of such cutter blocks
preferably two, to which we secure the cutters and which are driven by any con-
venient means. The carriage with the squared spindle is traversed over the first
rotating cutter block the cutters on which mould one side then the carriage is
moved back, the squared spindle is turned and the carriage again traversed over
the first rotating cutter block to mould the next side the operations being con-
tinued and repeated as described until all four sides have been moulded.
When it is desired to mould the baluster or other article octagonally, hexagon-
ally or of any other section than square we clamp one corner of the squared
spindle in a V groove in a suitably prepared pad attached to the sliding carriage
which is then moved forward to and passed over a suitable rotating cutter block and
by adjusting the spindle in the pad and traversing the carriage over the cutter
block as often as necessary the baluster is moulded to the desired section
It is obvious that the baluster may be moulded throughout of the same section
or partly of one form and partly of another section or sections and that when
required several rotating cutter blocks may be employed to obtain the desired
variations of form.
The cutters which we employ are V shaped or variations of the V formed by
say omitting one side or blade or removing a part or parts of the metal at the
point of the V or elsewhere according to the form required.
These cutters are formed with or fixed on shanks which are bolted to the
rotating cutter block and the form and set of their cutting edges insures a lead
that is to say the blade meets the wood diagonally and so comes gradually into
action thereby cutting the wood without tearing it.
When moulding long or delicate spindles we may arrange the cutters on the
cutter block so that the first cutters remove a portion of the width of the squared

page_text: spindle and the cutters on the succeeding block or blocks remove the remainder
and thus the piece of timber is not liable to spring and be torn.
In the accompanying three sheets of drawings
Fig. 1 is a side elevation partly in section of a wood moulding machine made
according to our invention for moulding balusters and the like, Fig. 2 is a plan
view of Fig. 1 and Figs. 3, 4, 5, 6 and 6 are detailed views of parts of the carriage
fitted upon the table of the machine.
Fig. 7 is a view of a baluster moulded upon our improved moulding machine
provided with two cutter block spindles and with cutters made according to our
invention.
1
Figs. 1 and 2 represent a moulding machine with two rotating cutter blocks
1 mounted upon spindles 2 driven by bands from any convenient rotating shaft,
and on these cutter blocks are secured cutters made of any of the different V forms
according to our invention No. 3521 of. 1898, of even date herewith. On the
table 3 of the machine a carriage 4 is mounted in slideways so that it can be moved
to and fro as required and in the carriage 4 is a transverse T headed slot in which
are fitted adjustably two bolts for securing two clamping plates 6, and an ad-
justable angle bracket 7 is also secured to the carriage 4 so as to hold a squared
piece of timber on its flat sides as usual and also upon its edges for moulding
polygonal forms.
A suitably shaped piece, of timber 8 is held against the fence upon the carriage 4
by clamps 9, and screws 10 which pass through screwed holes in the clamping
plates 6, and the position lengthwise of the timber is regulated by moving the
adjustable bracket 7, and a centre pin 11 screwed through the angle bracket 7
is employed to centre the timber, the bracket 7 also carries an adjustable
clamp 12 made with a V groove for holding the timber in its position, see Fig. 6^.
When the piece of timber is properly secured by the clamps it is ready to be
moulded, and if for a comparatively short and strong baluster all the cutters for
the full width of the baluster can be mounted upon one cutter block; when the
machine is set in motion the carriage 4 is traversed by hand far enough to carry
the piece of timber 8 across the cutter block the cutters on which cutting across
the grain of the wood mould one side, the clamps are then slackened and the
timber turned say one quarter round, the carriage moved back and the timber
again turned one quarter round and clamped and traversed across the cutters,
and this is repeated until the moulds have been cut on all four sides.
When moulding long or delicate balusters or the like as in Fig. 7 we employ two
or more cutter block spindles and place part of the cutters on one block and the
others on the remaining block or blocks so that the first cutters remove a portion
of the width of the squared timber say between A and A and the cutters on the
succeeding block or blocks remove the remaining portions between A and B
and thus the strain on the timber is reduced and it is not liable to spring and
be torn.
We have shown and described a convenient arrangement for clamping and
holding a suitably shaped piece of timber in different positions on the carriage 4,
and if four sides only are to be moulded we lay the timber on the carriage 4,
and give it a quarter turn at each setting; but if the piece of timber is to be
moulded into octagonal form we mould the four sides as described and then place
the four corners of the timber one after the other in the notches formed to receive
them in the clamps 9, holding down screws 10, and on the side and bottom of
the carriage 4, and proceed to mould the four surfaces into eight by adjusting
the timber and traversing it over the cutters as before described. It will be
readily understood that parts of the balusters could be moulded on more
sides than other parts, for instance certain parts of a baluster might be moulded
on four sides and other parts on six or more sides.
In the example illustrated by Fig. 7 the baluster is moulded octagonally
between A, B while the remainder between A A is left square, but it will be readily

page_text: understood that this is only intended as an example of one out of the many forms
or patterns which may be produced.
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. The improved wood moulding machine having a rotating cutter block spindle
or two or more such spindles with cutter blocks provided with cutters of V shape
or variations of the V shape in cross section, in combination with a carriage
and means for adjusting and clamping the timber to be moulded, all substantially
as and for the purposes herein set forth.
2. In a wood moulding machine, the construction, use and application of the
special form of carriage herein shown and described whereby the squared timber
can be set on its corners and further moulded into hexagonal, octagonal or other
forms as required.
