IMPROVEMENTS IN DRIVING BELTS
Year: 1885

page_text: I ALFRED GEORGE BROOKES of the firm of Wm Brookes & Son of 55 & 56
Chancery Lane in the County of Middlesex Fellow of the Institute of Patent
Agents, do hereby declare the nature of my invention for IMPROVEMENTS IN
DRIVING BELTS, to be as follows:-
The invention relates to improvements in that description of driving belts, for
which an application for letters patent, bearing number 12861, was filed on the
27th day of September 1884; and the object of the present improvements is to
thicken such belts partly, lengthways in such a manner, in order that they may be
capable of being placed upon the pulleys in any convenient way and yet be
always correctly in position for operation.
To attain this object the belts are composed of a suitable number of longitudinal
strips, which are to be all of. an equal, or nearly, an equal breadth, and these strips
are superposed overlapping in series or placed in the form of steps one above
another and connected by cementing sewing rivetting lacing or other suitable
means, thus producing belts of step or stair-shaped cross section, which will bring
the thickening strip or portions of belt serving to give greater thickness always in
its proper place upon the driving pulleys, viz; upon that part of the pulley
whereon the inner edge of the belt-the one which describes the curve of the
shorter radius is running.

page_text: I ALFRED GEORGE BROOKES of the firm of Wm Brookes & Son of 55 & 56
Chancery Lane in the County of Middlesex Fellow of the Institute of Patent
Agents, do hereby declare the nature of my invention for IMPROVEMENTS IN
DRIVING BELTS, and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
This invention relates to improvements in that description of driving belts, for
which William Phillips Thompson obtained letters patent N° 12861 dated the
27th day of September 1884 (on a communication from Carl Otto Gehrckens, before
mentioned) and the object of the present improvements is to thicken such belts
partly lengthways in such a manner that they may be capable of being placed
upon the pulleys in any convenient way and yet be always correctly in position
for operation.
To attain this object the belts are composed of a suitable number of longitudinal
strips, which are to be all of an equal, or nearly an equal breadth, as illustrated by
the accompanying drawing in which Figure 1 is a top view, Figure 2 a cross
section of my belts, while Figure 3 shows the belt in operation.
These strips a. a¹ a³ et cetera are superposed overlapping in series or placed in
the form of steps one above another, and connected by cementing, sewing, rivetting,
lacing or other suitable means thus producing belts of step or stair-shaped cross
section, which will bring the thickening strip or portions of belt serving to give
greater thickness thereto always in its proper place upon the driving pulleys,
according to which ever side of the belt comes into operation.
Having now particularly described and ascertained the nature of the said
Invention, and in what manner the same is to be performed, I declare that what
I claim is
In driving belts the combination of two or more longitudinal strips of an equal
or nearly an equal breadth which are connected in such a manner as to form belts
of stair-shaped cross section.
Dated this 6th day of November 1885.
