1866. A communication from abroad by Thomas Roberts White and

America.
I, GEORGE DAVIES, of No. 1, Serle Street, Lincoln's Inn, in the County of
Middlesex, and No. 87, St. Vincent Street, in the City of Glasgow, Civil
Engineer and Patent Agent, do hereby declare the nature of the said Inven-
tion for "AN IMPROVED FABRIC TO BE USED FOR THE MANUFACTURE OF DRIVING
BELTS, HOSE, AND FOR OTHER USEFUL PURPOSES," (a communication to me
from abroad by Thomas Roberts White and William Glenn Bedford, of
Philadelphia, Pennsylvania, United States of America,) to be as follows:-
This Invention consists of a fabric composed of wires interwoven with cotton
or hemp threads, or threads of other fibrous material, the fabric thus made
being used for driving belts, hose, other tubing, and for other useful purposes.
This Invention also consists of a fabric composed of threads and wires inter-
woven and coated with waterproof material substantially as described hereafter,.
the said fabric being strong, durable, and light, and especially applicable for
forming tubes to be used with drills in boring artesian wells. The weaving
of this fabric may be rapidly effected in a loom differing but little from those
of ordinary construction. Experiments have proved that driving belts thus

continued use owing to the surface becoming gradually smooth by contact
with the pulleys. By making the wires at each edge somewhat thicker and
stronger than those in the middle the quality of the belt is improved. Both
sides or only that side of the belt in contact with the pulleys may be coated
with gum elastic or gutta percha, and the wire may be varnished or coated
with shellac, or otherwise prevented from rusting, or they may be clothed
with fibrous material prior to being woven. In making the tubing of this
fabric the loom in which it is usual to weave hemp hose may be used in a
manner too well known to need description, the wires being the warp and
extending longitudinally in line with the tubing while the weft threads extend
round the tube and are interwoven with the wire warp. Secondly, the fabric
of wire and threads thus interwoven is passed through a solution of india-
rubber, gutta percha, or other waterproof -material or composition, which
adheres to the fabric in the form of a thin coating. A thin sheet of rubber
or other suitable material is then applied to each side of the newly coated
fabric, and the whole is passed between rollers so arranged as to exert upon
it a heavy pressure, the rubber sheets being thus caused to adhere firmly to
the coating. The new fabric thus formed is ready for use as soon as it leaves
the rollers.
In some instances it will be best to use a fabric in which the warp is composed
of thread and the weft of wire. Both warp and weft may consist of both thread
and wire.
