I, SAMUEL HOLLAND, of 65, Wheler Street, Openshaw, Manchester, in the
County of Lancaster, Wood Machine Foreman, do hereby declare the nature of
this invention to be as follows:-
The invention relates to an improved guard for circular wood-moulding machines
for preventing accidents to workmen tending such machines, the object being to
provide a simple yet efficient guard for the aforesaid purpose and one which can
be easily adjusted to the work in hand.
In carrying out my invention I construct a guard of a suitable material and in
plan somewhat semi-circular in shape so as to partly surround the revolving cutter
head, and in elevation sufficiently deep to afford protection to the hands of the
workman. At one side the guard has a projecting lug or ear by means of which
it may be bolted to a knee or angle bracket the upper arm of which is slotted to
allow of the guard being adjusted to suit the size of the timber being passed
under it in contact with the cutters. The other arm of the bracket is also slotted
and adjustably secured to the table of the moulding machine.
When the guard is in position the workman proceeds to operate in the usual
way and should the revolving cutters cause the wood to be jerked back, as is
frequently the case, his hand is brought into contact with the guard and not
with the cutters. In this way most serious accidents are prevented.

Improved Guard for Circular Wood-moulding Machines.
I, SAMUEL HOLLAND, of 65, Wheler Street, Openshaw, Manchester, in the
County of Lancaster, Wood Machine Foreman, do hereby declare the nature of
this invention and in what manner the same is to be performed, to be particu-
larly described and ascertained in and by the following statement :-
The invention relates to an improved guard for circular wood-moulding machines
for preventing accidents to workmen tending such machines, the object being to
provide a simple yet efficient guard for the aforesaid purpose and one which can
be easily adjusted to the work in hand.

page_text: The invention will be fully described with reference to the accompanying draw-
ings, in which,
Fig. 1 is an elevation of the improved guard,
Fig. 2 a plan and
Figs. 3 and 4 similar views of a modified form of guard.
In carrying out my invention and referring more particularly to Figs. 1 and 2
1 construct a guard a of a suitable material such as cast or malleable iron, brass
or the like and in plan somewhat semi-circular in shape as seen in Fig. 2 though
it may be completely circular so as to partly or entirely surround the revolving
cutter head band in elevation sufficiently deep to afford protection to the hands
of the workman. At one side the guard a has a projecting lug or ear e by means
of which it may be secured by bolt d to a suitable knee or angle bracket e the upper
arm of which is slotted or otherwise arranged to allow of the guard being vertically
adjusted to suit the size of the timber being passed under it in contact with the
cutters f. The other arm of the bracket is also slotted and adjustably secured
to the table of the moulding machine, by means of a set screw h or the like.
The lug c is preferably recessed as shown so as to engage with a web i on the knee
bracket and prevent its being twisted out of position, or in place of the web the
lug may be recessed sufficiently wide to embrace the knee bracket at its full
width.
Instead of always adjusting the guard a vertically by slacking the bolt and
moving it up and down the knee bracket, I sometimes provide the guard with one
or more plates j slotted vertically and secured to a by bolts and wing nuts or the
like as shown in Figs. 3 and 4. These plates can be adjusted vertically as
desired and also moved round the guard a without moving it at all the latter
being slotted at 7 for the purpose. It will be seen that the plates j limit the size
of the opening beneath the guard a and so lessen the liability of accident to the
workman, and that all the parts being adjustable the guard can be placed in
the most suitable position for the work in hand.
When the guard is in position the workman proceeds to operate in the usual way
and should the revolving cutters cause the wood to be jerked back, as is frequently
the case, his hand is brought into contact with the guard and not with the cutters.
In this way most serious accidents are prevented.
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. A guard for wood-moulding machines consisting of a semi-circular or circular
plate such as a attached to a suitable angle bracket such as e and capable of being
adjusted to suit the work in hand, substantially as described.
2. In a guard for wood-moulding machines the combination of a plate such as a,
angle bracket such as e and plates such as į all adjustable to suit the work in
hand substantially as described.
3. The improved guard for wood moulding machines constructed and arranged
substantially as described and as shown either in Figs. 1 and 2 or in Figs. 3
and 4 of the accompanying drawings.
