PROVISIONAL SPECIFICATION left by the said Alfred William Moore at the
Office of the Commissioners of Patents on the 6th September 1877.
ALFRED WILLIAM MOORE, of Hackney, in the County of Middlesex. "IMPROVE-
MENTS IN MACHINES FOR CUTTING AND TRIMMING THE HAIRS OR BRISTLES OF
BRUSHES."
This Invention consists in improvements in machines for cutting and trimming
the hairs or bristles of brushes, whereby such operation is effected in a more
expeditious, perfect, and economical manner than is the case with the apparatus at
present in use.
The apparatus is, by preference, mounted on a table of any desired form, and
consists of a bed plate provided with gudgeons or bearings, in which is mounted an
axle or spindle furnished at one end with a band wheel. Through the centre of the
said axle or spindle is a longitudinal slot for the reception of a metal plate, which
is passed through and fixed therein in such a manner that the longitudinal edges
thereof, which are shaped and formed for the purposes of cutting, project in a
corresponding manner on each side of the axle. A horizontal cutting plate is so
arranged that on the before-described axle being caused to revolve the cutting edges
of the plate held therein will alternately come into close proximity to the cutting
edge of the said horizontal plate, the respective plates being so arranged, and the
cutting cutting edges thereof bevelled in such a manner, that the said edges at first
come into close proximity only at one side, and then gradually to the other side as the
axle revolves, when the last-mentioned cutting edge of the plate in the axle passes
below that of the horizontal plate, the opposite cutting edge of the former comes

page_text: into action with that of the latter, as will be well understood. The said horizontal
cutting plate is mounted by means of a centre pin and quadrant, so that it can be
tilted as the cutting edge wears away, on supports, so constructed that the base
thereof can slide laterally on the bed plate of the machine, and be secured in any
desired position. Above the cutting plates are provided suitable supports or guides
for the stock or frame of the brush, such supports or guides being so connected
with uprights having vertical slots therein that they may be raised, or lowered, or
set at any angle, and secured in the desired position by means of screws and nuts.
The said uprights may also slide independently in a lateral groove formed in the
bed plate, in order to accommodate the supports or guides to any variation in the
size of the stock or frame of the brush under treatment.
The action of the machine is as follows:-The stock or frame of the brush is
placed upon the supports or guides, the hairs or bristles downwards, and is then
moved by hand backward and forward, while at the same time the axles is caused
to revolve. The length to which it is desired the hair or bristles should be cut
having been regulated by raising or lowering the supports or guides, as before
described, any hairs or bristles projecting beyond such length will come between,
and be cut off by the cutting edges of the plates. The surface of the hairs or
bristles may in this manner be cut perfectly level, or to any desired angle or
angles.
When it is desired to give a rounded surface to the hairs or bristles of the brush
the above-described supports or guides are removed, and above the plates, and at
right angles to the cutting edges thereof, is placed an inclined rod, the lower end of
which is hinged or pivoted to a vertical slotted bar, which is connected with a
support, attached to the front of the table by means of a screw pin and nut in such
a manner that the slotted bar, and consequently the lower end of the rod, can be
raised or lowered as may be desired. The upper end of the inclined rod rests in a
recess in the upper part of a slotted bar connected with the back part of the hori-
zontal plate, and which bar may be raised or lowered in the same manner as that
already described. Upon the above-described rod is loosely placed a ring or collar,
to the lower part of which is attached a frame, provided on the under surface with
holders or clutches for the purpose of securing the stock or frame of the brushes,
the distance between such holders or clutches being made adjustable by means of
nuts and screws, for the purpose of accommodating the same to any variation in
the size of brush under treatment. On the brush having been secured in the manner
above described, with the hairs or bristles downwards, it is placed immediately
above the cutting edges of the plates. The machine is set in action, and by
oscillating the ring or collar on the inclined rod, and moving it up and down the
same, the desired form will be given to the surface of the hairs or bristles of the
brush.
The motive power is communicated to the axle either by an endless band passing
over the above-mentioned wheel, and actuated by a treadle crank and fly wheel
placed beneath the table, or by a winch handle, or by any other suitable or con-
venient means.

"IMPROVE-
MENTS IN MACHINES FOR CUTTING AND TRIMMING THE HAIRS OR BRISTLES OF
BRUSHES."
My said Invention consists in improvements in machines for cutting and trimming
the hairs or bristles of brushes, whereby such operation is effected in a more
expeditious, perfect, and economical manner than is the case when it is performed
by hand, or by means of the apparatus at present in use.
The apparatus is, by preference, mounted on a table of any desired form, and
consists of a bed plate provided with bearings, having mounted therein an axle or
spindle, furnished at one end with a drum or band wheel. Through the centre of
the said axle or spindle is a longitudinal slot for the reception of a metal plate,
which is passed through and fixed therein in such a manner that the longitudinal
edges thereof, which are shaped and formed for the purposes of cutting, project in a
corresponding manner on each side of the axle. A horizontal cutting plate is so
arranged that on the before-described axle being caused to revolve the cutting edges
of the plate held therein will alternately come into close proximity to the cutting
edge of the said horizontal plate, the respective plates being so arranged, and the
cutting edges thereof bevelled in such a manner, that the said edges first come into
close proximity only at one side, and then gradually to the other side as the axle
revolves. The said horizontal cutting plate is mounted by means of a centre pin
and quadrant, so that it can be tilted as the cutting edge wears away on a support,
so constructed that the base thereof can be moved on the bed plate of the machine
and secured as required. Above the cutting plates are provided suitable supports
or guides for the stock or frame of the brush, such supports or guides being so con-
nected with uprights having vertical slots therein that they may be raised, or
lowered, or set at any angle, and secured in the desired position by means of screws
and nuts. The said uprights may also be moved independently in a lateral groove
formed in the bed plate, in order to accommodate the supports or guides to any
variation in the size of the stock or frame of the brush under treatment.
The action of the machine is as follows:-The supports or guides having been
fixed at the desired height above the cutting blades the stock or frame of the brush
is placed thereon, the hairs or bristles downwards, and moved backward and for-
ward, whilst at the same time the axle is caused to revolve. The length to which
it is desired the hair or bristles should be cut having been regulated by raising or
lowering the supports or guides, as before described, any hairs or bristles projecting
beyond such length will come between, and be cut off by the cutting edges of the
plates. The surface of the hairs or bristles may in this manner be cut perfectly
level, or to any desired angle or angles.
When it is desired to give a rounded surface to the hairs or bristles of the brush
the above-described supports or guides are removed, and above the plate, and at
right angles to the cutting edges thereof, is placed an inclined rod, the lower end of
which is hinged or pivoted to a vertical slotted bar, which is connected with a
support attached to the front of the table by means of a screw pin and nut in such
a manner that the slotted bar, and consequently the lower end of the rod, can be
raised or lowered as may be desired. The upper end of the inclined rod rests in a
recess in the upper part of a slotted bar connected with the back part of the hori-
zontal plate, and which bar may be raised or lowered in the same manner as that
already described. Upon the above-described rod is loosely placed a ring or collar,
to the lower part of which is attached a frame, or the said rod may be passed
through slots in bars attached to the frame, the position of the rod in such slots
being regulated by means of screws or other suitable contrivances. The frame is
11004

page_text: provided on the under surface with holders or clutches for the purpose of securing
the stock or frame of the brushes, the distance between such holders or clutches being
made adjustable by means of nuts and screws, for the purpose of accommodating
the same to any variation in the size of brush under treatment. On the brush
having been secured in the manner above described, with the hairs or bristles
downwards, it is placed immediately above the cutting edges of the plates, the
machine is set in action, and by oscillating the frame on the inclined rod, and
moving it up and down the same, the desired form will be given to the surface of
the hairs or bristles of the brush.
When it is desired to give a concave, convex, or corrugated surface to the brush,
the inclined rod is bent or formed accordingly, as will be well understood.
I will now proceed to refer to the annexed Drawings, from which the nature of
my said Invention will be more clearly understood.
