We OTTLEY LANE PERRY, of N° 7 Bedford St, Cotton Spinner, and BENJAMIN
ALFRED DOBSON, West Field, Machinist, both of Bolton, in the County of Lancaster,
do hereby declare the nature of said Invention for IMPROVEMENTS IN THE MANU-
FACTURE OF BRUSHES, MATS, AND OTHER SIMILAR ARTICLES, and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement:-
"
Our invention consists in the application of certain machinery (specified below)
driven by hand or power and actuated by gearing or strap or band driving for tho
purpose of cutting short, trimming, levelling, corrugating or otherwise varying the
surface presented by the ends of bristles, or other materials used in place of bristles
which are set in a frame work or fabric after the manner of brushes or mats.
We employ a diagonal or vertical knife roller or rollers in connection with a fixed
knife bar or bars. These cutting rollers revolvo in fixed but adjustable pedestals.
The brush or brushes, being supported on a traversing elevator table, and either
revolving in bearings on this table by means of a central shaft or spindle, or (as
the character of the work may require) fastened firmly to the said table, can be
applied with a suitable pressure to the cutting knives or vice versa.
We employ a traversing serrated "scissor bar" placed on another scissor bar
either stationary or traversing in the opposite direction; the form of the scissor
bar being similar to those used in certain reaping machines and, in a smaller form
in horse clipping machines. The brushes are revolved or traversed as previously
described with a suitable pressure against the cutters.
We employ an apparatus whereby the bristles or other materials as above
described are burned off by gas jets placed either in direct contact with the bristles
or through the intervention of metal or other plates raised to a red heat.
Wo use the above threo methods either separately or in combination with one
another.
And in order that our Invention may be fully understood and readily carried
into effect we will describe the accompanying three Sheets of Drawings reference
being had to the figures and lettors marked thereon.
Similar letters refer to similar parts throughout the several views.
On Sheet 1.-Figures 1 and 2 are end elevations Fig. 3 a front view and Fig 3*
a part plan of machinery which we employ according to our Invention for cutting,
trimming corrugating or otherwise varying the surface of brushes, mats, or other
similar articles and Fig. 4 is a transverse section of one form of knife roller which
wo employ.
a is the frame of the machine; b the knife roller carried by the shaft b' in
bearings which may be adjusted on the frame a by the adjusting screws c of which
there is one at either end of the machine. The knife roller b is in this instance
provided with three spiral or helical blades b' and arranged to work with a so-called
"doctor" knifof fastened to a plate g adjusted by the screws gl. The arrangement
and form of the blades fixed to the knife roller as well as to the doctor knife ƒ may

page_text: be varied, such arrangement including straight knives parallel with the axis of the
roller. The knife roller shaft b¹ is actuated at one end directly by the main
pulley g of the machine and conveys its motion to the pulley g fitted on an
adjustable stud secured to a hanging arm g. This is effected by the worm d
which (fixed on the other end of the knife roller shaft) drives the worm wheel d'.
On the same shaft d' with this worm wheel, is another worm e' which again drives
a worm wheel e, secured to a short shaft e to which is keyed a pulley e³ that
drives the pulley go to which the pulley g' is secured. The hanging arm g* swivels
on a bearing through which the knife roller shaft passes. The shaft h of the
brush being placed in its bearings i and provided with a suitable grooved pulley h¹
is driven from the pulley g' by a short loop of banding which can be quickly put
on the pulleys by pulling the hanging arm forward into the position shown in Fig. 2
and then allowing the arm by its own weight to fall back to a vertical position to
tighten the band: a guiding fork 98 fixed to the side of the frame enables the arm
to swivel freely without any undue strain on the bearing. The arrangement of
the double pulleys on the hanging arm enables the speed of the brush spindle to be
readily regulated as required the bearings i may be adjusted on the table ; to and
from the knife roller b by means of adjusting screws k, one at each end of the
machine and to insure a movement absolutely parallel to the knife roller we fix a
bevel wheel at the end of each screw which bevel wheels gear into bavel
wheels fixed on the cross shaft which may be turned by a hand wheel : on
the end of the brush shaft h³ is a rocking cam h³ (see Figs. 3 and 3*) which is
arranged to work in a fork h' fastened to one of the adjustable bearings i. This
rocking cam traverses the brush during its revolution.
The brush shown in Figs. 1, 2 and 3, on the shaft h², is of circular form and may
represent either a single brush such as is used for stripping purposes on a carding
engine, or a series of brushes (such as are used in combing machines) strung on a
suitable spindle or shaft,
Fig. 5 is an end elevation in section. Fig. 6 a front elevation and Fig. 7 a part
plan of a brush cutting machine fitted with a traversing scissor bar or cutter
according to our Invention.
On Sheet 2.-Figs. 9 and 10 are similar views to Figs. 5 and 6, but showing
parts of the machine on a larger scale. Figs. 11 and 12 are views of another form
of scissor bar or cutter which we employ.
In these views. A driving shaft gives motion to the brush shaft h by means
of gearing and a hanging arm as already described: m is a stationary bar to the
lower edge of which a series of fingers or bevelled knives is secured, or the bar and
its finger knives may all be made in one piece; this bar is itself supported at each
end on the table by the brackets m'. Face to face with the stationary bar m is a
traversing bar n similarly fitted but the knife fingers differently shaped and not so
long as those in the stationary bar. The traversing bar works in a suitable slide
on the stationary bar and is actuated at one end by a cam o (affixed to the driving
pulley g) which works against a bowl o¹ connected by a bracket of to the traversing
bar n, the action of which cam is reciprocated by a spiral spring o³. The fingers
on the two bars are kept in close contact by springs p which are fitted with
antifriction bowls p² as shown. In Figs. 11 and 12 the stationary knife edges
tbroughout the greater part of their length are at right angles to the bar while the
knife edges of the traversing bar are V shaped or bevel.
On Sheet 3.-Fig. 13 is a front elevation and Fig. 14 an end elevation of our
improved machinery or apparatus for singeing or trimming brushes and Figa 15
and 16 are front and end views respectively of an apparatus in which the heated
plate is traversed by hand for singeing and trimming brushes.
In Figs. 13 and 14.-A stripper or other roller brush is shown mounted in
adjustable bearings in the brackets r, the upper part of which project over a
chamber 8, concave on its upper surface; this chamber is heated by gas supplied
through a perforated pipe s¹ provided with an atmospheric bulb outside either end
of the chamber 8, or other forms of applying burning gas may be employed. The
:

page_text: brush is adjusted to the desired height by turning the hand wheel t which gives
motion to the bevel wheels t¹ t' gearing into the wheels at fast on the screws t³ t³
which pass through the frame and are screwed into the lugs ¹ of the brackets r:
the chamber 8 is then heated and the brush set in motion, the bristles being.
gradually trimmed and levelled and the desired quantity burned off. The concave
surface 8 may be perforated and may be heated by other agents than gas.
The brushes can be readily and rapidly brought into and out of contact with the
hot surface by turning the hand wheel t.
In Figs. 15 and 16.-A roller brush is shown in fixed bearings u; v is a pair of
adjustable brackets which support a bar or rest v¹: a handle w is forked at w¹ and
secured to the plate x: two studs y are secured to the handle w to form a guido
for it.
To singe and trim a roller brush the plate is brought to a red heat in a suitable
furnace or fire and then placed with the handle w resting on the bar : revolving
motion is given to the brush by a band pulleys, while the hot plate is moved to
and fro by the operative who guides the handle by holding the studs y in contact
with the bar or rest until the bristles are sufficiently trimmed.
Short roller or circular brushes may be operated upon by any of our improved
machines by securing them in any convenient manner to a shaft or axle which is
placed in the brush bearings in the manner described.
Although, we have shown and described our Invention applied to trimming
roller brushes it may be applied to brushes, mats, and other similar articles with a
flat or other surface by varying the details of the machine.
Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed, wo declare that what
we claim is
1. A revolving adjustable knife roller with a fixed knife bar or bars for the
purpose of cutting, trimming, and levelling the bristles of roller and other brushes
and mats held in an adjustable or traversing frame or bearings, substantially in the
manner shown and described.
2. The application of "scissor bars" for trimming, lovelling, or corrugating the
bristles of roller and other brushes or mats supported in an adjustable frame or
bearings, substantially in the manner shown and described.
3. The application of machinery for supporting roller brushes or mats in
adjustable bearings, combined with stationary, revolving or traversing, heated
surfaces for burning off the bristles, substantially in the manner and for the
purposes described.
4-The application of a forked bar and rest for supporting and guiding a heated
plate for burning off the bristles of roller or other brushes or mats, substantially
as shown and described.
