Improvements in Wood Planing Machines.
I, NORMAN TAILBY, of 76 Summer Row, in the City of Birmingham, Timber
Merchant, do hereby declare the nature of this invention to be as follows:-
This invention relates to machines for surfacing, jointing, bevelling, or otherwise
planing or cutting deals, match boarding, and other similar wood work.
The object of my invention is to construct and arrange feeding mechanism for
a planing machine, in such a manner that the machine may be employed with a
self-feeding motion for surfacing, thickening and like operations, and be
used also for jointing, edging, bevelling and similar purposes, as an ordinary hand-
planing machine.
may
In carrying my invention into effect, I mount my feeding mechanism upon an
arm or bracket preferably made up of two side pieces of cast or wrought iron or
other material, and tied or connected together by suitable bolts or connecting
pieces. I pivot one end of the bracket upon a shaft or spindle carried by hangers
or bearings suspended from the table of the machine. The bracket projects over
and above the table and at the extreme end of the bracket I provide an adjustable
stop piece to keep it at the required minimum height above the table.
Near to the free end of the bracket, I fix a spindle for carrying the feeding
roller, the periphery of which is preferably formed of india-rubber, and imme-
diately over the revolving cutter, I fix the pressure roller for keeping the wood in
position upon the table during the cutting operation.
Upon one end of the feed roller spindle I mount a pulley and drive the same by
belting or chain gearing from a pulley secured to the spindle at the back end of
the machine, forming the pivot of the arm or bracket as herein before described.
This spindle is driven by belting from the countershaft usually employed for
transmitting motion to the cutter spindle, fast and loose pulleys being provided
with belt shifting gear for readily stopping and starting the shaft as required.
To vary the rate of feed I sometimes employ cone pulleys upon the feed roller
spindle and the rear or pivot spindle, or upon the latter spindle and the counter-
shaft as may be more convenient. To obtain the necessary pressure of the rollers
upon the wood, I employ weights preferably circular discs of iron and mount the
same, as required, upon the pivotted bracket above the pressure roller.
When requiring to use the planing machine for jointing, edging, bevelling, and
similar purposes, the pivotted arm with the self-feeding mechanism is turned over,
on its pivot shaft or spindle, until its free end rests upon the floor level. In this
manner the table of the machine is left clear and may be used for the same
operations and in the same manner as an ordinary hand planing machine.
I do not limit the application of my invention to any particular form or type of
planing machine, but modify the details and arrangement of my improved feeding
mechanism for application to existing and new machines of varying design and
construction.

I, NORMAN TAILBY, of 76 Summer Row, in the City of Birmingham, Timber
Merchant, do hereby declare the nature of this invention and in what manuer the
same is to be performed, to be particularly described and ascertained in and by
the following statement :-
This invention relates to machines for surfacing, jointing, bevelling, or otherwise
planing or surface-cutting deals, match boarding, and other similar woodwork.
The object of my invention is to construct and arrange feeding mechanism for
a planing machine, in such a manner that the machine may be employed with a
self-feeding motion for surfacing, and like operations, and may be used also for
jointing, edging, bevelling and similar purposes, as an ordinary hand planing
machine.
· In the accompanying sheet of explanatory drawings to be hereinafter referred
to :-
Figure 1 is a front elevation of a wood planing machine having my improved
feeding mechanism fitted thereto.
Figure 2 is a plan of the feeding mechanism.
The same reference letters in the two views indicate the same parts.
In carrying my invention into effect, I mount my feeding mechanism upon an
arın or bracket preferably made of two side pieces A A¹ of cast or wrought iron
or other material, and tied or connected together by suitable bolts or connecting
pieces. I pivot one end of the bracket upon a shaft or spindle B carried by
hangers or bearings such as C C¹ suspended from or attached to the table of the
machine. When in use the bracket projects over and above the table and is
supported and adjusted to the required height by means of adjusting stops or
screws such as D D¹.
Near to the free end of the bracket, I fix a spindle for carrying the feeding
roller E the periphery of which is preferably formed of india-rubber, and adjacent
thereto and over the revolving cutter F I mount the pressure roller G for keeping
the wood in position upon the table during the cutting operation.
Upon one end of the feed roller spindle I mount a pulley or wheel H and drive
the same by belting or chain gearing from a pulley or wheel J secured to the
spindle B at the back end of the machine, forming the pivot of the arm or
bracket as herein before described. This spindle is driven by belting running on
the pulley K from the countershaft usually employed for transmitting motion to
the cutter spindle, fast and loose pulleys being provided with belt shifting gear
for readily stopping and starting the shaft, or the belt may be thrown off the
pulley K when the feeding mechanism is not required.
To vary the rate of feed I sometimes employ cone pulleys upon the feed roller
spindle and the rear or pivot spindle, or upon the latter spindle and the counter-
shaft as may be more convenient. To obtain the necessary pressure of the rollers
upon the wood, I sometimes employ weights preferably circular discs of iron and
mount the same as required upon the pivot bracket above the pressure roller.
When requiring to use the planing machine for jointing, edging, bevelling, and
similar purposes, the pivotted arm with the self-feeding mechanism is turned over,
on its pivot shaft or spindle to the underside of the table as illustrated by dotted
lines in Figure 1. In this manner the table of the machine is left clear and may
be used for the same operations and in the same manner as an ordinary hand
planing machine.
I do not limit the application of my invention to any particular form or type
of planing machine, but modify the details and arrangement of my improved

page_text: feeding mechanism for application to existing and new machines of varying design
and construction.
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 1
claim is :-
1. The improved arrangement of a wood planing machine with self feeding gear
enabling the one machine to be employed for surfacing, and like operations, or
for jointing, edging, bevelling and like work, substantially as herein described.
2. In wood planing machines the use of a pivotted arm or bracket for carrying
the feeding gear, having a pivot connection with the machine enabling it to be
turned back out of position when not in use, substantially as and for the purposes
hereinbefore described and as illustrated in the accompanying drawings..
3. The construction of an arm or bracket for pivotting to a wood planing
machine and having a suitably driven feed roller fitted thereto with pressure roller
and adjusting stops substantially as and for the purposes hereinbefore described and
as illustrated in the accompanying drawings.
4. In wood planing machines the combination of an arm or bracket carrying
the feeding mechanism, with a pivot shaft transmitting the required motion to the
feed roller, arranged substantially as and for the purposes hereinbefore described
and as illustrated in the accompanying drawings.
