An Improved Guard for Surfacing or Hand Feed Planing Machines.
I, JOIN KERSHAW, of Railway Iron Works, Hebden Bridge, in the County
of York, Saw Mill Engineer, do hereby declare the nature of this invention
to be as follows:-
The object of my invention is to construct a guard for surfacing or hand feed
planing machines, which may be easily and quickly adjusted for either surfacing,
edging, chamfering or rebating boards and the like, and so as to effectually and
automatically guard the operator from injury during the operation.
At the back end of the machine I fix a rod or shaft, upon this rod or shaft is
mounted a suitable arm preferably the length of the back table, this arm carries
the cutter guard which is of peculiar shape and projecting at an angle from the
table, so that as the board or the like is being fed to the cutter it is pushed
against this angle of the guard, raising the guard and allowing the board to be
operated upon; as the board is moved forwards until the hands of the operator
come in contact with the guard, the operator then moves the board from beyond
the cutter, and as the board passes from underneath the guard, it falls and
covers up the cutter, thereby preventing possibility of accident to the operator.
For edging, chamfering, and rebating boards, the arm carrying the guard is
moved along the rod or shaft sufficient for the purpose required, so that only
that part of the cutter required to operate upon the board is unguarded during
this operation...
For extra width of machines, the arm carrying the guard is mounted on the
rod or shaft, preferably in a central position over the table, and the guard
duplicated and made to slide one within the other telescopic fashion.

I, JOHN KERSHAW, of Railway Iron Works, Hebden Bridge, in the County
of York, Saw Mill Engineer, 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:-
The object of my invention is to construct a guard for surfacing or hand feed
planing machines, which may be easily and quickly adjusted for either surfacing,

DESCRIPTION OF DRAWINGS.
Fig. 1 is a plan of my improved guard for wood planing machines.
Fig. 2 is a side elevation of Fig. 1.
Fig. 3 is a side elevation of a hand feed planing or surfacing machine with
my improvements applied.
"
At the back end of the machine, I fix a rod or shaft A, hinged upon this rod
or shaft is mounted a suitable arm B, preferably the length of the back table,
this arm carries the cutter guard C which is of peculiar shape and projecting at
an angle D from the table E, so that as the board or the like is being fed to the
cutter G it is pushed against this angle D of the guard, raising the guard and
allowing the board to be operated upon, as the board is moved forwards until
the hands of the operator come in contact with the guard, the operator then
moves the board from beyond the cutter, and as the board passes from underneath
the guard, the guard falls and covers up the cutter thereby preventing possibility
of accident to the operator.
For edging, chamfering, and rebating boards the arm B carrying the guard
is moved along the rod or shaft A sufficient for the purpose required so that only
that part of the cutter required to operate upon the board is unguarded during
this operation.
For extra width of machines, the arm B carrying the guard C is mounted on
the rod or shaft A preferably in a central position over the table, and the guard C
duplicated, and made to slide one within the other, telescopic fashion.
A counterpoise weight H, placed upon the arm B behind its hinge or pivot
assists in raising the guard.
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:
-
1. In surfacing or hand feed planing machines the use and employment of a
guard C, adjustable and automatic, in the manner and for the purposes, substan-
tially as set forth.
