PROVISIONAL SPECIFICATION.
Improvements in Band Conveyers for Minerals and the like.
We, N. GREENING & SONS LIMITED, of Crown Street, Warrington, in the
County of Lancaster, Wire Manufacturers and Metal Perforators, and WILLIAM
HOLBROOK of Crown Street, Warrington, Clerk, do hereby declare the nature
of this invention to be as follows:-
The metallic conveyer bands which are used for the conveyance of coal ores
cement and other like substances are frequently constructed of metallic links
connected together with transverse pins. After continued use it is found that
the heads or ends of these pins become worn so that they are free to move in
the direction of their length and the band is thus liable to be disabled and may
become a source of danger.
In order to obviate this defect, we construct and arrange the edge or selvedge
links in such a manner that they protect the heads or ends of the pins, which
thus cannot become worn in ordinary use.
For this purpose we may either form projections or recesses in the edge or
selvedge links, or in those of such links through which the pins pass or in the
links adjacent thereto. If projections are employed, these are arranged on each
side of the head or end of the pin and extend laterally to a sufficient distance
to protect the pin from wear at the edges of the band. When recesses are
employed they are, similarly, of a sufficient depth to protect the heads or ends
of the pins which are contained in the recesses.
The edge or selvedge links themselves may be formed of any suitable material,
but it is preferred to construct them of bar steel or iron and in the latter case
to case-harden the links.

COMPLETE SPECIFICATION.
Improvements in Band Conveyers for Minerals and the like.
We, N. GREENING & SONS LIMITED of Crown Street Warrington in the
County of Lancaster, Wire Manufacturers and Metal Perforators, and WILLIAM
HOLBROOK of Crown Street Warrington, Clerk, do hereby declare the nature
of this invention, and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
The metallic conveyer bands which are used for the conveyance of coal ores
cement and other like substances are frequently constructed of metallic links
connected together by transverse pins. After continued use it is found that the
heads or ends of these pins become worn so that they are free to move in the
direction of their length and the band is thus liable. to be disabled and may
become a source of danger.
In order to obviate this defect, we construct and arrange the edge or selvedge
links in such a manner that they protect the heads or ends of the pins, which
thus cannot become worn off by ordinary use.

page_text: For this purpose we may either form projections or recesses in the edge or
selvedge links, or in those of such links through which the pins pass or in the
links adjacent thereto. If projections are employed these are arranged on
each side of the head or end of the pin and extend laterally to a sufficient
distance to protect the pin from wear at the edges of the band.
When recesses
are employed they are, similarly, of a sufficient depth to protect the heads or
ends of the pins which are contained in the recesses.
The edge or selvedge links themselves may be formed of any suitable material,
but it is preferred to construct them of bar steel or iron, and in the latter case
to case-harden the links.
We will more particularly describe our said invention with reference to the
accompanying drawings in each of the figures of which similar letters are
employed to denote similar parts.
Figure 1 is a partial plan,
Figure 2 a cross section, and
Figure 3 a partial end view of a conveyer band constructed to embody our
improvements.
Figure 4 is a horizontal longitudinal section,
Figure 5 a cross section, and
Figure 6 a side view of a modified construction of the selvedge links.
Figure 7 is a horizontal section,
Figure 8 a cross section, and
Figure 9 a side view of a further modification in the construction of the
selvedge links.
Figure 10 is a horizontal section,
Figure 11 a cross section, and
Figure 12 a side view of another modification.
The selvedge links A A¹ may obviously be variously constructed for the pro-
tection of the heads or ends B of the transverse pins, and the pins themselves
may either be formed with returned ends as shewn in the drawings and as
preferred, or they may be formed with a solid head and a returned end or
otherwise as may be desired. In all cases the links forming the body of the
band may be of any known or convenient construction such as that for example
illustrated by Figures 12 and 3. In these figures, alternate links A are double
cranked, the cranked portions serving to protect the ends of the pins. The
intermediate links A¹ may be perfectly flat.
In the modification illustrated by Figures 4, 5, and 6, the ends of the links A
are turned to form about a half circle as illustrated and the thus formed U-shaped
part may be perforated to receive the turned over end of the pin.
The modification shewn by Figures 7, 8, and 9 resembles the form illustrated
by Figures 1, 2, and 3, but that the flanges of the intermediate links A are
slotted to receive the ends of the pins.
In the construction represented by Figures 10, 11, and 12, the links A are
formed of channel iron or steel the sides of which project above the ends of the
pins and so protect them from wear. In this case the ends of the pins may be
turned down within the channel of the links A.
It is obvious that many alternative forms of links may be constructed so as
to be equivalent to those herein described, and illustrated by the drawings, and
we desire it to be understood therefore that we do not limit ourselves to these
forms and arrangements.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
A metallic conveyer band having selvedge links with projections or recesses

page_text: constructed and arranged to protect the ends or heads of the transverse pins,
substantially as hereinbefore described and as illustrated by the accompanying
drawings.
