FREDERICK SEARLE PARKER, of 17, Bedford Row, in the County of Middlesex
Gentleman. IMPROVEMENTS IN STRAPS OR BANDS APPLICABLE FOR DRIVING
BELTS AND FOR OTHER PURPOSES." [A communication from abroad by Monsieur
George de Beerski, of Paris.]
This Invention has for its object improvements in straps or bands applicable for
driving belts and for other purposes. For this purpose I form a strap or band
with a central core of wire gauze, and on either side of it I place a sheet composed
of ground cork and india-rubber solution, the ordinary canvas backing with which
such sheets are made being placed outwards. The inner surfaces of the sheets are
well covered with india-rubber solution, which is allowed to dry on the sheets.
Afterwards the sheets are put together with the wire gauze between them, and they
are submitted to heavy pressure, by which means the cork sheets on either side of
the wire gauze are forced into the interstices of the gauze and unife one with the
other, holding the gauze between them. The sheets of cork material are made
somewhat broader than the gauze so as to form a smooth edge to the band.
The canvas backing of the cork sheets may be covered with leather or fabric
secured to it by india-rubber solution, or may be varnished or japanned. In place
of wire gauze strips of metal may be enclosed in the centre of the bands.

FREDERICK SEARLE PARKER, of 17, Bedford Row, in the County of Middlesex,
Gentleman. "IMPROVEMENTS IN STRAPS OR BANDS APPLICABLE FOR DRIVING
BELTS AND FOR OTHER PURPOSES." A communication from abroad by Monsieur
George de Beerski, of Paris.
This Invention has for its object improvements in straps or bands applicable for
driving belts and for other purposes. For this purpose I form a strap or band
with a central core of wire gauze, and on either side of it I place a sheet composed
of ground cork and india-rubber solution, the ordinary canvas backing with which
such sheets are made being placed outwards. The inner surfaces of the sheets are well
covered with india-rubber solution, which is allowed to dry on the sheets, after-
wards the sheets are put together with the wire gauze between them, and they are
submitted to heavy pressure, by which means the cork sheets on either side of the
wire gauze are forced into the interstices of the gauze and unite one with the other,
holding the gauze between them. The sheets of cork material are made somewhat
broader than the gauze so as to form a smooth edge to the band.
The canvas backing of the cork sheets may be covered with leather or fabric
secured to it by india-rubber solution, or may be varnished or japanned. In place
of wire gauze strips of metal may be enclosed in the centre of the bands.
In carrying out the Invention I proceed as follows:-A composition of powdered
cork and india-rubber solution, or it might be other cementing solution, is first
prepared. The composition is then spread on canvas or other fabric, and its surface
afterwards well covered with liquid india-rubber and left to dry. The combined
fabric is cut into strips of the width of band desired, and strips of wire netting of
somewhat lesser width are also prepared, then the two surfaces of the fabric which
are spread with india-rubber are placed on the two sides of the wire netting leaving
the canvas or other backing outside. The whole is now submitted to a violent
pressure, which is intended to make the composition penetrate through the meshes
of the netting, and thus causes them to adhere through the netting, which they hold
firmly between them. The outside of the material can then be covered with leather
or any other material, which is affixed by means of the india-rubber solution or any
other similar composition, or they may be varnished or lacquered.
Care must always be taken to give the cork composition a little wider surface
than the netting, so that the borders may join and leave a certain space for securing
them to connect several widths together, or in order to attach the two borders
together for making any tubular articles.
The net work may be replaced by bands of metal disposed as above, but the net
work is preferable.
When great resisting power is required, several sets of net work and coverings may
be superposed.
Having thus described the nature of the Invention, and the manner of performing
the same, I would have it understood that I claim the manufacture of straps or bands
applicable for driving belts and for other purposes, substantially in the manner
herein-before described.
In witness whereof, I, the said Frederick Searle Parker, have hereunto set my
hand and seal, this Ninth day of July, in the year of our Lord One
thousand eight hundred and seventy-eight.
FRED. SEARLE PARKER. (L.S.)
