COMPLETE SPECIFICATION.
Improvements in Machine Belts.
I, HERBERT JOHN ALLISON, of the firm of Allison Brothers, of 52 Chancery Lane,
London, in the County of Middlesex, Patent Agents, do hereby declare the nature of
this invention, which has been communicated to me from abroad by Charles A.
Schieren, Belt Manufacturer, of Brooklyn, in the County of Kings and State of New
York, United States of America, and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement:—
The invention relates to belts for driving machines.
The improvements consist in the following construction and combination of parts
which will first be fully described and the improvements then pointed out in the
claims.
Fig. 1 is a plan view of a section of a belt, partially in section, showing my
improvements.
Fig. 2 is a plan, also partially in section, of a portion of a belt, showing a modifica-
tion of my invention.
Fig. 3 is an edge view of the belt shown in both Figs. 1 and 2.
Fig. 4 is a modified form of connecting link.
In the drawings, a represent a series of links, preferably adapted to break-joints
with each other, and which constitute the belt.
bare a series of pins which pass partially through the belt, and upon which the
links, preferably of leather, are pivoted.
The belt is designed more particularly for running upon what are termed " crown
pulleys," and for this purpose is made laterally flexible. To secure this result 1
interpose one or more series of flexible connecting links c (Fig. 1) and d (Fig. 2).
Links e, Fig. 1, are curved so as to overlap and thereby interlock each other in a
longitudinal line.
The connecting links d (Figs. 2) are straight.
The pins b, are inserted alternately through the opposite sides and ends of the
links band d.
Both series of links c and d, are shown in section, in the figures, in order to clearly
show how the pins 6 pass through and are headed therein.
b

page_text: In Fig. 1 a pin b passes through the links a on one side of the belt, and through
one end of a connecting link c, while the pin b, opposite thereto, passes through the
adjoining link €, and the two pins lie in the same line with their heads adjacent.
In Fig. 2, the pins & pass only partially through and are headed in opposite ends
and sides of the connecting link d. It will be understood that there are two pins b
lying in the same axial line passing through each line of break-joints, and which pins
abut against each other at their ends, but are independent otherwise.
Fig. 4, shows a longer connecting link e than the links c or d. The pins b are
inserted likewise alternately from opposite sides thereof. This connecting link may
be used in lieu of links c or d, or conjointly therewith. The connecting links are
torsionally flexible, which admits of lateral flexibility to the belt. More than one
series of connecting links may be interposed along the width of the belt.
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. A driving belt composed of parallel sections, each comprising a series of links
immediately adjacent to each other the full width of the belt, and provided with one
or more series of single connecting links lying adjacent to the belt sections, and a
series of pins passed through the sections and through opposite ends of said connecting
links, alternately from opposite sides thereof, substantially as set forth.
2. A driving belt composed of longitudinal sections, a series of connecting flexible
links overlapped at the ends and a series of pins inserted alternately from opposite
sides through the belt sections, and through the ends of the connecting links,
substantially as set forth.
