We, JOHN ANGELO HEWETSON and WALTER LAMBERT, trading as Hewelson and
Lambert, Dansom Lane Saw Mills, Hull, in the County of Yorkshire, Timber
Merchants, do hereby declare the nature of this invention to be as follows:-
The object of our invention is to provide an improved guard or shield for use
with various kinds of machines which are fed by means of feed rollers, also circular
saws and the like, for the purpose of preventing the limbs of the operators from
being caught in the machinery.
For the purpose of our invention, we employ a guard or shield preferably
pivotted on the frame of the machine at any suitable part, but in such a position
that it prevents the operator from unconciously getting his hand between the feed
rollers or the part which he is feeding.
This guard or shield may be formed of bars, laticework or the like, to allow
of the operator seeing the part of the machine which he is feeding, it is also
preferably set at an angle in an outward direction, so that it cannot be drawn in
in the direction of the feed rollers or the like, it can also be made adjustable by
means of sliding rods or the like and set screws or other setting device, so that the
bottom part can be highered or lowered to suit the thickness of material passing
through, and the bottom cross-piece may be a roller so as to prevent friction if the
material in passing through bears against it.
The guard or shield is placed at a suitable distance from the feed rollers, or
the blade, as in circular saws, so that the operators limbs or clothing would not
get near those parts by accident.

COMPLETE SPECIFICATION.
An Improved Guard or Shield applicable to Machines Fed by Means of
Feed Rollers, Circular Saws, or the like, for the purpose of
Preventing the Limbs of the Operators from being Caught in the
Machines.
We, JOHN ANGELO HEWETSON and WALTER LAMBERT, trading as Hewetson and
Lambert, Dansom Lane, Saw Mills, Hull, in the County of Yorkshire, Timber
Merchants, 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 our invention is to provide an improved guard or shield for usė

page_text: with various kinds of machines which are fed by means of feed rollers, also circular
saws and the like, for the purpose of preventing the limbs or clothing of the
operators from being caught in the machinery.

DESCRIPTION OF DRAWINGS.
Represents a front view of our improved guard or shield fitted to a
planeing machine, and articulated to the balance rods of the machine.
Fig.
Represents a side view of Fig. 1, and
Fig. Represents a side view of the guard, articulated to uprights on the bed of
the machine instead of to the balance rods.
For the purpose of our invention, we employ a guard or shield preferably
pivotted or articulated on the frame of the machine, at any suitable part, but in
such a position that it prevents the operator from getting his hands or other
limbs, or clothing between the feed rollers or the part which he is feeding.
Our improved guard is formed of bars, latticework or the like A, which may be
fitted to side pieces B, forming a frame, such bars or latticework being somewhat
open, allow of the operator seeing the part which he is feeding.
The guard is preferably set at an angle, sloping in an outward direction as
shown in Figs. 2 and 3, so that it cannot be drawn in in the direction of tho
feed rollers or the like C of the machine, it can also be made adjustable by means
of sliding rods or the like 1) fitting within or on the side pieces B preferably, and
set screws E or other suitable setting or fixing device, so that the space between
the bottom of the guard and the bed of the machine can be increased or decreased
as desired to allow of different thicknesses of material being passed through, and
the bottom cross piece may be a roller or rollers F so as to prevent friction if the
material in passing through bears against it.
The guard is provided with arms & which are articulated as at. H, to the bed
or other part of the machine, in Figs. 1 and 2 they are shown as articulated to the
balance rods K, of the machine, but in Fig. 3 they are shown as articulated to
uprights L on the machine bed; in either case the guard will turn in suitable
directions on its joints H, allowing of it being lifted up or raised or lowered to
allow of various thicknesses of material being passed under it, so that in
conjunction with its lengthening rods D it would allow any thickness of material
which the feed rollers would take to pass through, also by this means it rests
lightly on the material passing under it.
".
Our improved guard is placed at a suitable distance from the feed rollers, or the
blade as in circular saws, so that the operators limbs or clothing cannot get near
those parts by accident.
Having now particularly described and ascertained the nature of this
invention, and in what manner the same is to be performed, we declare that what
we claim is: -
4
1. In connection with machines having a roller or similar feed, circular saws
or the like, the employment of a guard or shield consisting of bars, latticework or
the like A, attached to side pieces B forming a frame, and having lengthening
rods adjustable by means of set screws E or other suitable means, arms G,
joints H, and with or without roller F, in the manner and for the purposes 4
substantially as shown and described.
2. The combination of the parts forming a guard or shield in the manner and for
the purposes substantially as shown and described in the accompanying specification
and drawings.
