Improvements in Machinery or Apparatus for Cutting and Forming
Octagonal, Hexagon, Square, or other Angled Pillars, Baluster,
and other like Articles.
I WILLIAM GREENWOOD of 15 Crossley Terrace Halifax in the County of York
Cabinet Maker, do hereby declare the nature of my said invention to be as follows:-
This invention has for its object the cutting and shaping of wood to square hexagon
octagonal or other number of angled surfaces for pillars baluster rails table or chair
legs and for other purposes.
According to this invention I employ a rotary cutter or spindle having cutting tools
attached thereto and in combination is a platform or table having fences or guides.
The table has by eccentrics, cam plates cranks or other like devices a rising and falling
motion imparted thereto on a vertical line and in addition the said table or platform
has also lateral adjustment.
The wood to be operated upon is faced on one side and one of its ends trued so
that when placed on the table or platform and against the fence and secured thereon
by a clamping piece and bolts the vertical movement of the table will bring the wood
within operation of the cutting tool, and as the wood is trued until all its surfaces are
cut the required form is secured.
In case of ornamental designs soon as one or more surfaces are cut a duplicate
rest is placed on the table for the wood to rest upon.

Improvements in Machinery or Apparatus for Cutting and Forming
Octagonal, Hexagon, Square, or other Angled Pillars, Baluster,
and other like Articles.
I, WILLIAM GREENWOOD of 15 Crossley Terrace, Halifax, in the County of York,
Cabinet Maker 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 has for its object the cutting and shaping of wood to square, hexagon,
octagonal, or other number of angled surfaces for pillars, baluster rails, table or chair
legs, and for other purposes.
According to this my invention I employ a rotary cutter or spindle having cutting
tools attached thereto and in combination therewith is a platform or table having
fences or guides. The table has by eccentrics cam plates, cranks, or other like devices
a rising and falling motion imparted thereto on a vertical line and in addition the said
table or platform has also lateral adjustment.
وو
The wood to be operated upon is faced on one side, and one of its ends "trued
so that when placed on the table or platform and against the fence and secured thereon
by a clamping piece and bolts, the vertical movement of the table will bring the
wood within operation of the cutting tools and as the wood is "trued" until all its
surfaces are cut the required form is secured.
In case of ornamental designs soon as one or more surfaces are cut a duplicate
rest is placed on the table for the wood to rest upon.
Such being the nature and object of my said invention, the following is a complete
description of same, references being had to the accompanying drawings forming a
part of this specification in which
Fig. 1 is a front elevation of my improved machine.
Fig. 2 is a side elevation in section of same.
According to this my invention I employ a rotary cutter or spindle 1 having cutting
tools 2 attached thereto, and in combination therewith is a platform or table 3 having
fences or guides 4. The table has by worm gear 5, or other like devices a rising and
falling motion imparted thereto on a vertical line, and in addition the said table or
platform 3 has also lateral adjustment by means of the handle 6 and screw 7.
"
The wood & to be operated upon is faced on one side, and one of its ends "trued
so that when placed on the table or platform 3 and against the fence 4 and secured
thereon by a clamping piece 9, the vertical movement of the table 3 will bring the
wood 8 within operation of the cutting tools 2 and as the wood 8 is "trued" until all
its surfaces are cut the required form is secured.
In case of ornamental designs soon as one or more surfaces are cut a duplicate rest
or templet 10 is placed on the table 3 for the wood 8 to rest upon.

page_text: The worm gear 5 on the shaft 5 is driven by two straps 11. 12, one of which is
crossed like 11, the other straight on the main driving pulley.
It will thus be seen that as the straps 11, 12 are moved to and fro on the pulleys
13, 14, 15, by means of the hand lever 13 and sliding rod and strap forks 14 that
the crossed belt 11 will be moved alternately from the fast pulley 14 to the loose
pulley 13, and that when the strap 11 is on the loose pulley 13, the straight strap 12
will be on the fast pulley 14, and vice versa, and thus the shaft 5 will be driven first
in one direction, and then in the other, and the bracket 64 and table 3 will be raised
or lowered as the case may be by means of the said worm gear 5 and the screws 7^.
Lateral adjustment is given to the table by means of the handle 6 and screw 7
working in the block 84 fast to the bracket 6 and the block 9A fast on the table 3.
The rotary cutter 1 is driven by means of a strap on the pulley 17. The clamp 9
which is raised and lowered by means of the screws 10 securely holds the wood 8
pressing on its whole length, and the wood is thus held more firmly than when held
by bolts at intervals.
Having now particularly 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 ;
Firstly The general construction, arrangement, and combination of mechanism
constituting the improved machine for purpose herein described and substantially as
illustrated by the drawings annexed.
Secondly The use of worm gear 5 sliding bracket 64 in combination with table 3,
having lateral motion, fence 4, clamp 9, revolving cutter 1, as illustrated and
described.
