I, WILLIAM PHILIPSON of Holland Street Iron Works, Astley Bridge near
Bolton in the County of Lancaster, Engineer and Machinist do hereby declare
the nature of my said invention to be as follows -
My invention relates to improvements in apparatus for cutting, trimming,
and levelling the surface presented by the ends of bristles or other materials
substituted therefore in the manufacture of circular brushes, and consists in
mounting stationary bars in suitable framework or fixings and fitted with adjustable
fixings provided with sliding blocks, operated by screws or other equivalents, to
carry the brush to be operated upon. The bristles or other materials are cut,
trimmed, or levelled by means of shears, the bottom, blade of which is stationary
and adjustable while the top blade is operated by a slotted or other lever; the
latter being worked by a pin attached to a crank on the end of the driving shaft.
The driving shaft with its connections is mounted in a suitable fixing which slides
on the two front stationary bars before named, being alid the entire length of the
brush under operation by means of a spur wheel geared into a rack extending the
full length between the framework or fixings supporting the machine.
The shears and their adjacent parts are slid by hand; the hand wheel is turned
when the shears operate on the bristles or their equivalents, the brush being turned
in its adjustable bearings by hand or by mechanical means.
The shears are
constructed to allow of various lengths of shearing being mounted in a slot and
provided with a quadrant which allows of adjustment at will.
When this machine is also intended for marking circular brush blocks for boring
a separate carriage is mounted on the top stationary bars, to which a pencil or
marker is attached. To this carriage is attached a cord or band which operates &
pulley on the end of the brush block centre and revolves the same according to
requirements while the carriage and marker are travelling the length of the brush
block. If desired the cord or band pulley can be placed in any suitable position
and connected to the brush block centre by suitable gearing or other equivalents.

Circular Brushes, which are also Applicable for Marking
Brush Blocks for Boring.
I, WILLIAM PHILIPSON of Holland Street Iron Works, Astley Bridge near
Bolton in the County of Lancaster, Engineer and Machinist, do hereby declare
the nature of my said invention and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement:-
My invention relates to improvements in apparatus for cutting, trimming,
and levelling the surface presented by the ends of bristles or other materials
substituted therefor in the manufacture of circular brushes, and consists in
mounting stationary bars in suitable framework or fixings. The stationary bars
are fitted with adjustable fixings provided with sliding blocks, operated by screws
or other equivalenta, to carry the brush to be operated upon. The bristles or other
materials are cut, trimmed, or levelled by means of shears, the bottom blade of
which is stationary and adjustable while the top blade is operated by a slotted or
other lever; the latter being worked by a pin attached to a crank on the driving
shaft. The driving, shaft, with its, connections is mounted in a suitable fixing
which slides on the two front stationary bars before named; being alid the entire
length of the brush under operation by means of a spur wheel geared into a rack
extending the fall length between the framework or fixings supporting the machine.
The shears and their adjacent parts are slid by hand; the hand wheel is turned
when the shears operate on the bristles or their equivalents, the brush being turned
fn its adjustable bearings by hand or by mechanical means. The shears are con-
structed to allow of various lengths of shearing being mounted in a slot and
provided with a 'quadrant which allows of adjustment at will.
When this machine is intended for marking circular brush blocks for boring
a separate carriage is mounted on the top stationary bars to which a pencil or
marker is attached. To the carriage is attached a cord or band which operates
a pulley on the end of the brush block centre, and revolves the same according to
requirements while the carriage and marker are travelling the length of the brush
block. If desired the cord or band pulley can be placed in any suitable position
and connected to the brush block centre by suitable gearing or other equivalents.
Fig. 1 is a front elevation of my improved machine for cutting, trimming, and
levelling circular brushes Fig. 2 is a sectional elevation through line A, B, and
Fig. 3 is a sectional elevation through line C. D.
In the fixings E are mounted the stationary bars F and G, the latter carrying
the adjustable fixings H provided with the sliding blocks I to receive the centres J
of the circular brush or brush stock K. The sliding block's I are operated in either
direction by the screws L and hand wheels M. To ensure the brush being
presented parallel with the shears the top side of the adjustable fixings are
graduated. The sliding blocks I are fitted with the thumb screws N to secure
the brush in position when being operated upon.. On the stationary bars F is
mounted the frame O carrying the hand wheel P, on the centre of which is fitted
the crank Q. The pin R in the crank Q operates the slotted lever S to which is

page_text: attached the top blade T of the shears pivoted on the centre U in the frame O.
The bottom blade T¹ of the shears is stationary on the centre U, and is held in
position by the end t coming in contact with the quadrant V, the latter being
employed for raising the bottom blade T¹ of the shears by depressing the end t,
thereby placing the shears at any suitable angle for cutting spirally. The top
blade T of the shears is attached to the slotted lever S by the pin S¹ to allow of
adjustment in either direction. The shears and fixing or frame O with its attach-
ments are slid by hand the entire length of the machine. In the crank Qis
mounted the pin u, forming a spur pinion with one tooth, which operates in the
slots X in the rack Y, by which the shears and frame O are travelled automatically
when cutting a brush or otherwise. The pin u is disengaged from the rack when
the shears commence cutting, and as it revolves with the crank it catches in the
next slot and travels the frame O on as required.
When trimming is being performed the rack Y is removed, which allows the
operator to turn the hand wheel P and shear the bristles as long as requisite, the
brush being turned by hand. After the space covered by the shears has been
trimmed sufficiently the frame O and shears are moved forward by hand to the
next stage or place requiring trimming.
The roller vunder the rack Y is attached to the frame O for the purpose of
preventing or minimising the spring of the rack Y when the pin u is in operation
with the slots X.
To prevent the frame O and shears sliding backward when operating on the
bristles, or their equivalents, the catch. W operates in the slots X in the rack Y;
the latter being carried the entire length of the machine and secured to the
fixings E.
When employing this machine for marking circular brush blocks for boring the
swivel arm or lever a is mounted on the centre b attached to the sliding frame O
on the bars F. The arm or lever a is fitted with the adjustable pencil or marker c
which is turned down onto the brush stock K as in Fig. 4. When marking
straight rows the pulleys d, e, f, are held fast which allows the index to be moved
or revolved with the brush by hand and set to the marks thereon. For the
purpose of marking the brush stock K by dots in lieu of a continuous line the
pencil or marker c is substituted by the needle pointed disc c¹ mounted on the arm
or lever a as in Fig. 5.
For the purpose of trimming and marking spiral circular brushes it is necessary
the brush or stock be revolved in proportion to its length. This is effected by
providing the band pulleys d, e, f, which are connected to the pulley g on the
sliding frame O by the band h, the latter being guided round the adjustable
pulley h¹ attached to the fixing E. The band pulleys are mounted in the
adjustable bearing k, and constructed to admit chucks of various sizes to receive
the centre J of the brush. The band pulleys shown on drawings are for operating
on brushes of the following lengths:d is for a brush 41 inches long; e 46 inches
long, and f 54 inches long, giving a spiral once round in the length of the brush.
I do not confine myself to these sizes as the same may be replaced with others
to suit any length of brush.
To
When the sliding frame O is being slid along the band h turns or pulls the
pulley round to which it is attached, thereby revolving the brush in proportion to
the travel of the frame O. The band h is attached to the rim of the pulleys in
the hole and slot as shown in Fig. 2, or in any other convenient manner.
maintain an uniform speed between the sliding frame O and the pulleys d, e, f, the
pulley m is provided with the "drag" band o and weight p, which also reverses
the brush ready for the next operation.
The index p is provided for the purpose of adjustment by which any number of
brushes can be constructed alike, the rim being marked or numbered, at which the
finger is placed according to the number of rows of bristles required. The
finger r is adjustable laterally to allow of the same being placed on any of the
rows indicated on the index.
