A Protection Guard for Uprigat Cutting Machines.
I, FREDERICK LOVE, of No. 24, Stanley Street, Groves, York, Joiner's Machinist,
do hereby declare the nature of this invention to be as follows:-
-
This invention relates to a protection guard for upright cutting machines such
as employed for planing or cutting mouldings and other similar work in which the
cutters or tools are carried in a vertical revolving spindle and with which accidents
frequently occur through the breaking or flying out of the cutters or tools.
Whilst guarding the operator from danger from these causes the protection
guard constructed in accordance with this invention permits of fresh cutters being
fixed and of the cutters being sharpened without inconvenience. The guard is
moreover easily adjustable to suit varying thicknesses of wood to be worked.
In carrying my invention into effect I form an arched hood of a suitable height
and width which I place upon the machine bed or table so as to cover the upright
spindle carrying the cutters.
In front of this hood I have a curved adjustable guard plate which encloses the
moulding or other work within the guard thus formed. A suitable slot or passage
way is cut in the sides of the arched hood so that the work may be fed to the
cutters. A suitable means of adjustment of the front guard plate to accommodate
different thicknesses of wood is to mount a bracket within the arched hood
aforesaid which carries a sliding bar to which the front guard plate is bolted or
otherwise attached.
.
The top of the arched hood is suitably slotted as is also the sliding bar aforesaid
through which slots a bolt passes and by means of a fly nut or the like said sliding
bar and with it the front guard plate may be fixed in any position desired.
Dated this 6th day of May 1898.

0 do hereby declare the nature of this invention and in what manner the same is to
he performed to be particularly described and ascertained in and by the following
statement:-
This invention relates to a protection guard for upright cutting machines such
as employed for planing or cutting mouldings and other similar work in which the

page_text: cutters or tools are carried in a vertical revolving spindle, and with which accidents
frequently occur through the breaking or flying out of the cutters or tools.
Whilst guarding the operator from danger from these causes the protection
guard constructed in accordance with this invention permits of fresh cutters being
fixed and of the cutiers being sharpened without inconvenience. The guard is
moreover easily adjustable to suit varying thicknesses of wood to be worked.
And in order that this my invention may be fully understood I will describe same
with reference to the accompanying drawings upon which Fig. 1 represents in
elevational view the vertical head as usually worked and without a protection guard.
Figs. 2 and 3 are, respectively, views of an arched hood and a front guard plate
used in carrying out this invention, and Figs. 4 and 5 are, respectively, a sliding
bar and a bracket used as a means of adjustment for affixing the front guard plate
in any required position relatively to the arched hood aforesaid, all as will herein-
after more particularly appear. Fig. 6 is a view in perspective shewing the arched
hood in position over the vertical head, and the adjusting sliding bar and bracket,
and Fig. 7 is a perspective view from the front of the apparatus shewing the front
guard plate in position and attached by means of the adjusting sliding bar aforesaid
to the arched hood before mentioned.
Similar letters of reference indicate like parts throughout the figures.
In carrying my invention into effect.I form an arched hood a of a suitable
height and width which I place upon the machine bed or table so as to cover the
upright spindle b carrying the cutters. In front of this hood a I have a curved
adjustable guard plate c which encloses the moulding or other, work within the
guard thus formed. A suitable slot or passage way
is cut in the side of the arched
hood a so that the work a may be fed to the cutters.
A suitable means of adjustment of the front guard plate to accommodate different
thicknesses of wood is to mount a bracket e within the arched hood aforesaid, which
carries the sliding bar f to which the front plate is bolted or otherwise attached as
at g Fig. 7. The top of the arched hood a is suitably slotted as at h and the sliding
bar is similarly slotted as at i and through these slots the bolt k is passed and
by means of a fly nut or the like said sliding bar and with it the front guard
plate c may be fixed in any position desired.
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
A protection guard for upright cutting machines consisting of the arched hood a
and front guard plate c, in combination with bracket e and sliding bar f;
constructed, arranged and operating, substantially as shewn and described.
