Improvements in the Manufacture and Treatment of Woven Driving
Belting and in Apparatus for Effecting the same.
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 improvements in the manufacture and treatment of
woven driving belting and to the means and apparatus for carrying the said
improved manufacture and treatment into practical effect. In order to lay the
fibres at the edges of woven belting and to impart a smooth antifrictional surface
and finish to the edges of such belting it has been the practice to rub wax or other
suitable glazing and smoothing material or compound upon the edges of the belting,
or to dip the ends of the roll of belting for a short distance into a shallow bath of
melted material so as to coat or impregnate the edges with the material. These
processes are however slow or ineffective. According to a portion of my invention
I arrange apparatus which dips the edges of the belting continuously into a bath
containing the material or ingredients in a fluid state which will coat and glaze the
edges of the belting. The apparatus which I have at present devised consists of a
long frame having at one end bearings to carry a roll of belting at or about the
centre, a tray or bath capable of being maintained at a suitable temperature; and
at the other end a suitable arrangement of taking up gearing for drawing forward
the belting and coiling it upon a beam or shaft. At each end of the bath is an
upright guide or eye by which the belting is turned from its horizontal position and
led over the bath in an upright position. In order to dip the lower edge in the
bath provide an adjustable pulley carried in a bracket above the centre of the
bath. This pulley can be adjusted so as to bear upon the upper edge of the belting
and so depress the lower edge which is thus dipped into the bath to the required
depth so as to take up a sufficiency of the melted wax or compound in the bath and
thus coat or impregnate the edge. After being thus dipped the belting passes
through the guide at the other end of the bath and gradually resuning its
horizontal position is drawn through the drawing rollers and coiled upon the beam
or shaft.
When one edge has been thus dipped the coil of belting at the drawing
roller end is lifted out of its bearings and dropped into the bearings at the feeding
end. The other edge is then dipped as already described. When both edges have
been thus treated the belting is afterwards passed between rapidly revolving
grooved polishing rollers which impart the required finish and polish to the dipped
or impregnated edges. These polishing rollers might be mounted on the dipping
machine or they might be mounted on a separate frame.
Another portion of my invention relates to means and apparatus for imparting a
smooth flexible surface to the faces of woven driving belting. As in the former
instance I provide a similar long frame having at one end the bearings to carry the
roll of belting to be fed through the machine and at the other end suitable drawing
and coiling mechanism.
At or about the centre of the machine I provide a drying chamber and in front
of the drying chamber 1 place a vessel or trough having ends capable of being
adjusted to, any width of belting. At the front of the vessel I arrange an adjustable
cover or doctor or spreader the lower edge of which presses upon the face of the
belting.
The vessel is filled with a stiff paste or pulp such as paper or other pulp or
compound of such a nature that it will retain sufficient elasticity when dry not to

page_text: crack when the belt is at work. A roller is placed at the front of the vessel and
just beneath the aforesaid cover, doctor or spreader.
The belt in passing through the paste in the vessel is coated therewith and in
passing out of the vessel and over the roller is acted upon by the doctor or spreader
which spreads a smooth, even and equal coating of paste upon the face. The
belting then passes into the drying chamber where the coating is dried, and after
leaving the drying chamber it is coiled upon a shaft or beam at the delivery end.
The taking up mechanism may be so arranged in both instances as to give an equal
speed of traverse to the belting from the commencement of the operation to the end.
By means of the processes hereinbefore indicated, I obtain a belting having
perfectly smooth edges and with a smooth and finished face which not only confers
a greatly improved appearance upon the belting but also increases its strength and
durability.
I do not confine myself to the exact disposition of parts or construction of
apparatus described in either instance as these might be modified. For example in
the edging machine instead of dipping the belting in a vertical position as described
I might lead the belting in a horizontal position past transferring rollers one or
more on each side of the belting the said transferring rollers working against the
edges of the belting and deriving a continuous supply of melted wax or other
material from a hot bath situated beneath the level of the transferring rollers and
raised and supplied to the transferring rollers by other wheels working half in and
half out of the melted wax or by a small pump or other raising means.
advantage of such an arrangement would be that both edges of the belting could be
coated at one operation.

COMPLETE SPECIFICATION.
Improvements in the Manufacture and Treatment of Woven Driving
Belting and in Apparatus for Effecting the same.
I 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 improvements in the manufacture and treatment of
woven driving belting and to the means and apparatus for carrying the said
improved manufacture and treatment into practical effect. In order to lay the
fibres at the edges of woven belting and to impart a smooth antifrictional surface
and finish to the edges of such belting it has been the practice to rub wax or other
suitable glazing and smoothing material or compound upon the edges of the belting
or to dip the ends of the roll of belting for a short distance into a shallow bath of
melted material so as to coat or impregnate the edges with the material. These
processes are however slow and ineffective. According to a portion of my
invention I arrange apparatus which dips the edges of the belting continuously
into a bath containing the material or ingredients in a fluid state which will coat
and glaze the edges of the belting.
For the purpose of rendering my invention more easily understood I will now
proceed to describe the same more particularly with reference to the annexed sheet
of illustrative drawings:
Referring to Figs. 1 and 2 of the drawings the apparatus as at present devised
consists of a long frame the whole of which I have not thought necessary to
illustrate, having at one end, for example towards the end marked X, bearings to
carry a roll of belting; at or about the centre is a tray or bath a capable of being
maintained at a suitable temperature by the steam space a' and at the other end Y

page_text: a suitable arrangement of taking up gearing not shown in the figs. for drawing
forward the belting 6 indicated in dotted lines and coiling it upon a beam or shaft.
The bath a which is slightly tilted as shown contains a supply of melted tallow,
wax or other suitable glazing or smoothing compound which is maintained at the
proper temperature by admitting steam through the pipe e to the steam chamber a¹
the temperature being kept at the required degree by observation of the steam
gauge d. The bath is supported on hangers e which depend from the side bars f
of the framing of the machine. At each end of the bath a is an upright guide or
eye with an adjustable pulley by which the belting is turned from the
horizontal position in which it comes from the roll and led over the bath in an
upright position. In order to dip the lower edge of the belting in the bath I
provide an adjustable pulley carried in a bracket h above the centre of the bath.
This pulley can be adjusted in a slot in the bracket so as to bear upon the upper
edge of the belting and so depress the lower edge which is thus dipped into the
bath to the required depth so as to take up a sufficiency of the melted wax or
compound in the bath and thus coat or impregnate the edge. To pack the orifice
through which the edge of the belt passes into the bath I employ spring presser
lips These pressers are operated through levers which are subject to the
pressure of springs & which so operate as to push the pressers towards each other
nipping the edge of the belting between them and pressing thereon sufficiently to
prevent any escape of the melted material past the edge. Packing pressers are
provided at the end marked X and although similar pressers are used at the exit
end marked Y their function is chiefly to scrape and smooth the edge and remove
any surplus of melted material. The levers are formed with handles so that the
levers can be operated by hand to relieve the edges from the pressure of the
packing and scraping lips i. At the exit end of the bath I fix a small platform a
which assists to raise the belting as it emerges from the melted material. After
being dipped the belting passes through the guide g at the other end of the bath
and gradually resuming its horizontal position is drawn through the drawing rollers
and coiled upon the beam or shaft. When one edge has been thus dipped the coil
of belting at the drawing roller end that is at the end marked Y is lifted out of its
bearings and dropped into the bearings at the delivery end. The other edge is
then dipped as already described. When both edges have been thus treated the
belting is afterwards passed between rapidly revolving grooved polishing rollers
arranged in accordance with the Specification of my application No. 17811 which
impart the required finish and polish to the dipped or impregnated edges. These
polishing rollers might be mounted on the dipping machine or they might be
mounted on a separate frame. Another portion of my invention relates to means
and apparatus for imparting a smooth flexible surface to the faces of woven driving
belting.
Fig. 3 is a longitudinal section and Fig. 4 a front view of the parts to which my
invention more especially relates. As in the former instance I provide a similar
long frame of which the side bars appear in the drawing having at one end
bearings to carry the roll of belting to be fed through the machine and at the other
end suitable drawing and coiling mechanism. The delivery, drawing and coiling
mechanism does not appear in the drawing. At or about the centre of the machine
I place a vessel or trough having sides capable of being adjusted by the right
and left hand screws and hand wheels n to any width of belting. At the front
of the vessel I arrange a pivotted cover or doctor or spreader o the lower edge of
which presses upon the face of the belting b.
The vessel is filled with a stiff paste or pulp such as paper or other pulp or
compound of such a nature that it will retain sufficient elasticity when dry not to
crack when the belt is at work. A roller p is placed at the front of the vessel /
and just beneath the aforesaid cover doctor or spreader. The belt in passing
through the paste in the vessel is coated therewith and in passing out of the vessel
and over the roller is acted upon by the doctor, or spreader which spreads a smooth
even and equal coating of paste upon the face.

page_text: The taking up mechanism may be so arranged in both the edging and surface
coating operations to give an equal speed of traverse to the belting from the
commencement of the operation to the end. By means of the processes herein before
indicated I obtain a belting having perfectly smooth edges and with a smooth and
finished face which not only confers a greatly improved appearance upon the belting
but also increases its strength and durability.
I do not confine myself to the exact disposition of the parts or construction of
apparatus described in either instance as these might be modified. For example in
the edging machine instead of dipping the belting in a vertical position as described
I might lead the belting in a horizontal position past transferring rollers one or
more on each side of the belting the said transferring rollers working against the
edges of the belting and deriving a continuous supply of melted wax or other
inaterial from a hot bath situated beneath the level of the transferring rollers and
raised and supplied to the transferring rollers by other wheels working half in and
half out of the melted wax or by a small pump or other raising means. The
advantage of such an arrangement would be that both edges of the belting could
be coated at one operation.
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
1. Coating and finishing the edges of woven driving belting in the manner and by
the means substantially as herein before described and shown.
2. Covering the surfaces of woven driving belting with a coating of suitable
paste, pulp or compound by passing the belting through a receptacle containing
semi-fluid material and subjecting it to the combined action of a roller and doctor
as it makes its exit from the receptacle so as to spread and smooth the coating of
material substantially as described and as illustrated.
