JAMES HEBBLEWAITE, Secretary to and EDWARD HOLT a Director of The Ancoats
Vale Rubber Company Limited, Palmerston Street, Ancoats, Manchester, in the
County of Lancaster, do hereby declare the nature of our invention for IMPROVEMENTS
IN THE PRODUCTION OF INDIA RUBBER DRIVING BELTS, BANDS AND TYRES to be as
follows:-
This Invention relates to improvements in the production of Belts, Bands, or Tyres
for driving or other purposes, made of India-Rubber or compounds containing India-
Rubber and Cotton or other descriptions of Canvas or fabric.
We prepare the Cotton or other descriptions of Canvas or fabric with a solution or
adhesive coating of India-Rubber or compounds containing India-Rubber. We, then,
cover the said fabric with a sheet or sheets of India-Rubber or compounds containing
India-Rubber, and we may so cover the said fabric either partially or wholly.
And in order to produce flutes, corrugations, indents, or any other form of impres-
sion upon the same, we employ presses, plates, moulds, or other suitable appliances,
having thereon, similar flutes, corrugations, or other form of impression which are
forced into the said surface or surfaces, the whole being vulcanized in the manner well
known to India-Rubber manufacturers and by these means we produce Belts, Bands
& Tyres having a strong grip upon the pulleys and thus avoid the "slipping" and
consequent loss of power; in preference to Driving Belts, Bands & Tyres inado with
smooth surfaces.
We may also apply this invention to the production of Belts, Bands & Tyres made
of India-Rubber or Compounds containing India-Rubber, alone; without combining
Cotton or other descriptions of Canvas or fabric.

Bands, and Tyres.
We, JAMES HEBBLEWAITE, Secretary, and EDWARD HOLT, a Director, of the
Ancoats Vale Rubber Co Limited, at Palmerston Street, Ancoats, Manchester, do
hereby declare the nature of our invention for "IMPROVEMENTS IN THE PRODUCTION
OF INDIA-RUBBER DRIVING BELTS, BANDS AND TYRES" and in what manner the same
to be performed, to be particularly described and ascertained in and by the following
.statement:—
This invention relates to improvements in the production or manufacture of belts,
bands, and tyres, for power driving or other purposes, which belts, bands, or tyres, are
composed of India-rubber and cotton or other fabrics; of India-rubber compounds
and fabrics; of other compounds containing India-rubber and fabrics; and also to
the manufacture of belts, hands, and tyres composed of India-rubber, or of India-
rubber compounds, or of other compounds containing India-rubber, without the aid of
the cotton or other fabrics above stated.
The compounds containing India-rubber are such as Balata mixed with India-rubber,
and Gutta Percha mixed with India-rubber, and also the ordinary or special compounds
containing India-rubber as are well understood in the trade.
We prepare the face of the cotton or other descriptions of canvas, or other fabric,
with a solution or an adhesive coating of India-rubber, or India-rubber compounds. We
then cover the said fabric, cither wholly or partially as may be desired, with a suffi-
cient thickness of India-rubber or any compound of India-rubber as beforenamed.
The prepared fabric may be folded and cut or otherwise doubled trebled or multplied
to the desired thickness, or the fabric may be woven of the desired thickness in the
first instance. We then subject the same to mechanical action either by means of
presses, plates, moulds, or other suitable appliances formed with flutes, corrugations,
or other indentations, and which are pressed upon the surface of the India-rubber, or
India-rubber or other compounds as named for the purpose of giving like fluted,
corrugated, or otherwise indented surface to the belting, either on one or both faces
thereof as may be desired. The whole is vulcanized or completed by heat or other
processes well known to India-rubber and Gutta Percha manufacturers.
By the foregoing means we produce belts, bands, and tyres, having flutes, corruga-
tions, or other indentations thereon, which have a strong grip upon the surfaces they
come in contact with, and hence avoid a large amount of "slip" and consequent loss
of power as compared with driving belts, bands, and tyres, made with smooth surfaces.
In manufacturing belts, bands, or tyres, according to our invention but without the
aid of the cotton or other fabric as a foundation, we prepare the India-rubber or the
compound in sheets or in moulds and act upon it by means of presses or other
mechanical appliances, and vulcanize or complete the same as has been already
described.
But that the improvements may be better understood we will by the aid of the
accompanying drawings proceed more fully to describe means employed by us.

page_text: DESCRIPTION OF DRAWINGS.
Figs. 1, 2, 3, and 4, shew examples of flutings or corrugations, and Figs. 5 and 6
shew forms of indentations or projections; all of which are shewn both in plan and
section.
But the design employed may be varied to any extent without departing from the
peculiar character of the invention.
:-
Having now particularly described and ascertained the nature of our said invention
and in what manner the same is to be performed, we declare that what we claim is :-
The manufacture of belts, bands, or tyres, for power transmitting or other purposes
composed of India-rubber and cotton or other fabric; or of India-rubber compound or
other compounds containing India-rubber and such cotton or other fabric; or of the
substances described containing India-rubber but without the cotton or other fabric,
having one or both faces thereof pressed, moulded, or otherwise formed into flutes or
corrugations, or with indentations or projections whereby such surface or surfaces are
roughened for the purpose and in manner substantially as shewn and described.
