Improvements in the Manufacture of Woven Driving Belting.
I FRANK REDDAWAY of Cheltenham Street Pendleton in the County of
Lancaster Manufacturer of Machine Belting do hereby declare the nature of this
invention to be as follows:-
My said invention relates to a mode of imparting greater finish to the surfaces of
woven driving belting. The materials or yarns from which driving belting is
woven are generally coarse and as a consequence the belting is apt to present
irregularities, excrescences, knots, loose ends and the like which are not removed
by any means at present used in the manufacture of belting and which present an
unsightly appearance, besides being positively detrimental to the perfect running of
the belting. According to my invention to remove the said irregularities I subject
the woven belting to the action of a clipping or cropping spiral such for example as
is used to clip or crop carpets, Nottingham lace and the like. A convenient
apparatus would consist of a frame provided at one end with bearings to carry a
shaft or beam upon which the belting to be clipped or cropped is wound. At the
other end is the taking up mechanism consisting of drawing rollers and a coiling
beam or shaft. Midway between the feeding coil and the taking up rollers is
situated the cropping or clipping spiral which consists as is well known of a
revolving cylinder carrying several spirally arranged cropping knives working in
conjunction with a fixed blade in the usual manner. The cropping cylinder is
carried in bearings in brackets which are adjustable towards and from the breast
beam or bar over which the belting passes while being acted upon by the revolving
spiral knives. The cropping cylinder thoroughly crops and dresses the surface of
the belting removing all hairs, knots, ends and lumps from the belting and greatly
improving its appearance and usefulness while rendering it more fit for undergoing
the subsequent dressing and finishing operations to which woven belting is sub-
jected. Each one or both surfaces of the belting may be cropped or clipped and
when it is desired to crop both sides I might either crop first one side and then the
other or I might arrange a second spiral cropping cylinder in the same machine so
as to crop both sides at one operation.

Improvements in the Manufacture of Woven Driving -Belting.
FRANK REDDAWAY of Cheltenham Street, Pendleton, in the County of
Lancaster, Manufacturer of Machine Belting do hereby declare the nature of this
invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement and accompanying
drawings:
My said invention relates to a mode of imparting greater finish to the surfaces of
woven driving belting. The materials or yarns from which driving belting is
woven especially when woollen or worsted or hair yarns are used are generally
coarse and as a consequence the belting is apt to present irregularities, excrescences,
knots, loose ends, and the like which are not removed by any means at present
used in-the-manufacture of belting and which present an unsightly appearance
besides being detrimental to the perfect running of the belting. According to my

page_text: invention to remove the said irregularities I subject the woven belting to the action
of a clipping or cropping spiral such for example as is used to clip or crop
carpets Nottingham lace and the like. A convenient apparatus would consist of a
frame provided at one end with bearings to carry a shaft or beam upon which the
belting to be clipped or cropped is wound. At the other end is the taking up
mechanism consisting of 'drawing rollers and a coiling beam or shaft. Midway
between the feeding coil and the taking up rollers is situated the cropping or
clipping spiral which consists as is well known of a revolving cylinder carrying
several spirally arranged cropping knives working in conjunction with a fixed blade
in the usual manner. The cropping cylinder is carried in bearings in brackets
which are adjustable towards and from the breast beam or bar over which the
belting passes while being acted upon by the revolving spiral knives. The
cropping cylinder thoroughly crops and dresses the surface of the belting removing
all hairs knots ends and lamps from the belting and greatly improving its
appearance and usefulness while rendering it more fit for undergoing the sub-
sequent dres.ing and finishing operations to which woven belting is subjected.
In order that my invention may be properly understood I will now proceed more
particularly to describe the same reference being had to the annexed sheet of
drawings.
Fig. 1 represents in vertical section so much of a machine as is necessary to
elucidate my invention.
Fig. 2 is a plan of Fig. 1.

In the drawing I have confined myself to an illustration of the clipping spiral
and adjacent parts without showing the delivery and coiling on beams. The
belting under treatment is indicated by the strong line marked a. The framing of
the machine is marked . The cropping spiral for dressing the surface of the
belting is mounted in bearings in adjustable brackets d. The brackets d have
tails which pass through and are secured in carrying blocks e which are firmly
bolted or secured to the blade bed which carries the fixed blade g. The edge of
the blade is adjusted in its proper position relatively to the spiral knives of the
revolving cropping cylinder c so that the belting a as it passes over the guide h
will be just sufficiently subjected. to the cropping action of the spiral a to clip off
the knots, loose ends, and other irregularities and imperfections which it is the
object of my invention to remove. The blade bed is formed with porters or
trunnions which are carried in bearing blocks i bolted to a bracket fixed to the
framing of the machine. The brackets d spiral c and blade bed and blade are
thus all carried on the trunnions f. The brackets d can be adjusted in the blocks e
so as to bring the spiral close up to the blade g. When adjusted the tails of the
brackets d are held in the blocks e by the set screws k. The spiral c may also be
adjusted vertically in its bearings in the brackets d and set against the blade g by
means of the set screws j. The brackets d and therefore the spiral c are adjusted
relatively to the guide or breast beam by the set screws 1. During revolution
the spiral c is reciprocated in the line of its axis by a lever m (see Fig. 2) pivotted
At one end the lever m is connected by a clutch fork o to a-flanged pulley
on the end of the shaft c¹ of the spiral c. At the other end the lever m is
worked by a camp on the end of the shaft q' of the top drawing roller q. The
object of reciprocating the spiral is to effect more equal work and wear. The
brackets with spiral c and fixed blade can be lifted entirely clear of the breast
beam or guide and of the belting by means of the pivotted levers which can be
operated from the end of the machine. The levers 7 are connected by links s to
extensions d² from the brackets d. By depressing the outward end of the pivotted
levers the brackets d with. their dependent parts can be turned up on the
trunnions so as entirely to clear the belting. The cropping spiral e is revolved
by a belt driven from the pulley which is carried on a shaft provided with
fast and loose belt pullies w x.

beam and beneath the spiral and from there to the drawing rollers
which are
driven as indicated in the drawings and by which it is passed on to the coiling-on
beam.
It must be understood that although I have elected to show and describe a
suitable and convenient form of cropping or clipping apparatus, nevertheless I do
not consider myself limited to such described and illustrated apparatus as the
forms and arrangements given to cropping and clipping mechanism are various
and it will be evident to competent persons that the cropping or clipping
mechanism could be greatly varied without departing from the spirit of my inven-
tion.
Each one or both surfaces of the belting may be cropped or clipped and
when it is desired to crop both sides I might either crop first one side and then
the other or might arrange a second spiral cropping cylinder in the same
machine so as to crop both sides at one operation.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed declare that what I
claim is
1) As means for dressing and finishing the surfaces of woven driving belting
as herein set forth the employment of revolving spiral clipping or cropping
rollers or mechanism substantially as described and indicated.
2) The general arrangement and combination of spiral clipping or cropping
mechanism for dressing the surfaces of woven driving belting substantially as
herein before described and as illustrated in the annexed sheet of drawings.
