Improvements relating to Driving Bands or Belts.
1, WILLIAM ROBERT LAKE; of the firm of Haseltine Lake & Co., Patent Agents,
Southampton Buildings, in the County of Middlesex, do hereby declare the nature of this
invention to be as follows:-
:-
This invention has for its object to provide improved means for protecting the
edges of machine belts, and especially those used to transmit power from a steam
engine to a threshing (or other) machine in an open field, from being abraded and
injured by contact with the guides used to keep the belt on the pulleys over which
it runs,
it being a common practice among those using threshing machines which
are driven by portable engines to guide the power communicating belt by stakes or
other fixed guides with which the edges of the belt are in rubbing contact and by
which said edges are rapidly worn so that in a short time the belt becomes useless.
This invention consists in a belt provided at its edges with a series of metallic
plates or guards, adapted to receive the wear and friction due to the guides against
which the edges of the belt run.
This invention also consists in a belt composed of a strip of fabric made in two or
more thicknesses, which are united by a row or rows of rivets extending lengthwise
of the belt.
In carrying out this invention a series of metal plates or guards are applied to the
edges of the belt and arranged so closely together that they effectually protect the
fabric from rubbing contact with the guides that may be used in connection with
the belt, without interfering with the flexibility of the belt.
The form and means of applying said guards may be variously modified, but it is
preferable to employ a series of disc headed rivets having prongs formed to pass
through the fabric and be clinched at the inner side thereof.
Such rivets are inserted in rows in the fabric along the lines on which it is to be
folded, preferably using strips or welts to reinforce the fabric along said lines.

page_text: The prongs being inserted and clinched hold the heads of the rivets against the
outer side of the fabric along the hereinbefore mentioned lines. The fabric is then
folded on the said lines and the rivet heads are thereby caused to extend across the
folded edges; the said heads being preferably of such size and construction that they
will be somewhat bent by the folding operation, and thus caused to project slightly
over the sides of the belt along the edges. The rivets may be attached very rapidly
by machinery and constitute a very simple and efficient means of protecting the
edges of the belt without interfering with its flexibility.
Any other suitable metallic guards, adapted to be attached to the fabric without
interfering with its flexibility, may be employed, such as a malleable tack, the shank
of which is adapted to be inserted and clinched in the fabric so that its head will bear
against the folded edge of the belt, and constitute a wearing or protecting plate; or
U-shaped plates of metal having clinching prongs on the diverging ends of their
jaws or side pieces may be used. The said plates are placed on the edges of the belt,
and their prongs inserted and clinched therein.
Other obvious modifications may be adapted without departing from the spirit of
this invention.
j
The folds or plies of the belt are united by rivets similar to those above described
the said rivets, being inserted in longitudinal rows in the belt after it is folded. As
many of the said rows may be employed as are desirable but it is preferable to
place two rows as closely as possible to the edges of the belt, and alternate the
rivets composing them with the edge guarding or protecting rivets, thus confining
the folds or plies of the belt closely together at these points.
It will be seen that the rivets used to connect the plies of the belt are much
stronger, more durable and easily applied than the stitches heretofore used for tho
same purpose.
Neither of the above described features of this invention viz., the edge protecting
plates nor the fold uniting rivets, are limited to belts made by folding a strip of
fabric, as they may be used with belts of any other suitable construction.
Wire staples may be inserted in the edge of the belt and form the wearing
surfaces the said staples being secured by having their prongs turned or clinched
within the belt.
In using these staples it is preferable to apply two or more rows to each edge of
the belt, if the staples extend longitudinally of the belt or if preferred the staples may
be placed crosswise of the edges of the belt.

Improvements relating to Driving Bands or Belts.
I, WILLIAM ROBERT LAKE, of the firm of Haseltine, Lake & Co. Patent Agents
Southampton Buildings, in the County of Middlesex, 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 :-
This invention has for its object to provide improved means for protecting the edges
of machine belts, and especially those used to transmit power from a steam engine to
a threshing or other machine in an open field, from being abraded and injured by
contact with the guides used to keep the belt on the pulleys over which it runs, it
being a common practice among those using threshing machines which are driven by
portable engines to guide the power communicating belt by stakes or other fixed
guides with which the edges of the belt. are in rubbing contact and by which said
edges are rapidly worn so that in a short time the belt becomes useless.
The said invention consists in a belt provided at its edges with a series of metallic
plates or guards, adapted to receive the wear and friction due to the guides against
which the edges of the belt run.
The invention also consists in a belt composed of a strip of fabric made in two or
nore thicknesses, which are united by a row or rows of rivets extending lengthwise of
the belt.
In the accompanying Drawings
Figure 1 represents a view of a piece of belting before it is folded into belt form
and having the protecting plates or guards applied to it along the lines on which it
is to be folded.
Figure 1ª represents a section on line Z Z Figure 1.
Figure 2 represents a piece of the folded belt having the edge guards.
Figure 3 represents a piece of the folded belt having the longitudinal rows of rivets
uniting its folds or plies.
Figure 4 represents a section on line x, x, Figure 2.
Figure 5 represents a section on line y, y, Figure 3.
Figure 6 represents a perspective view of the piece shown in Figure 2.
Figure 7 represents a perspective view of the rivet which constitutes the protecting
plates and serves to unite the folds of the belt shown in the preceding figures.
Figures 8, 9, 10, 11 and 12 13 and 14 represent modifications.
The same letters of reference indicate the same parts in all the Figures.
In the Drawings,
a Figure 1 represents a piece of duck, or other suitable fabric, of suitable width to
be folded along the dotted lines, b, b, and form a belt, c, substantially as is shown in
Figures 2, 3, 4, 5 and 6.
In carrying out this invention a sories of metal plates or guards are applied to the
edges of the belt arranged so closely together that they effectually protect the fabric
from rubbing contact with the guides that may be used in connection with the belt,
without interfering with the flexibility of the belt.

page_text: The form and means of applying the said guards may be variously modified, but
it is preferable to employ a series of disc headed rivets having prongs, e, e,
Figure 7, formed to pass through the fabric and be clinched at the inner side
theroof.
Such rivets are inserted in rows in the fabric along the lines b, b, on which it is to
be folded, preferably using strips or welts g, g, to reinforce the fabric along said lines,
as shown in Figure 1.
The prongs being inserted and clinched hold the heads of the rivets against tho
outer side of the fabric along the herein before described lines b, b. The fabric is then
folded on the said lines and the rivet heads are thereby caused to extend across the
folded edges, as shown in Figures 2, 3, 4, 5 and 6; the said heads being preferably of
such size and construction that they will be somewhat bent by the folding operation,
and thus caused to project slightly over the sides of the belt along the edges, as
shown in Figure 4.
The rivets may be attached very rapidly by machinery and
constitute a very simple and efficient means of protecting the edges of the belt without
interfering with its flexibility, as will be readily seen.
Any other suitable metallic guards, adapted to be attached to the fabric without
interfering with its flexibility, may be employed.
In Figures 8 and 9 I have shown a malleable tack, the shank of which is adapted
to be inserted and clinched in the fabric so that its head will bear against the folded
edge of the belt, as shown in Figure 9, and constitute a wearing or protecting
plate d.
Figures 10, 11 and 12 show U-shaped plates of metal having clinching prongs on
the diverging ends of their jaws or side pieces. The said plates are placed on the
edges of the belt, and their prongs inserted and clinched therein, as shown in
Figure 12.
Other equally obvious modifications may be adapted without departing from the
spirit of this invention.
In Figures 3 and 5 I have shown the folds or plies of the belt united by rivets
similar to those above described; the said rivets, which are lettered to distinguish
them from the edge protecting rivets, being inserted in longitudinal rows in the belt
after it is folded. As many of the said rows may be employed as are desirable, but
it is preferable to place two rows as closely as possible to the edges of the belt, and
alternate the rivets composing them with the edge guarding or protecting rivets, thus
confining the folds or plies of the belt closely together at these points.
It will be seen that the rivets used to connect the plies of the belt are much
stronger, more durable and easily applied than the stitches heretofore used for the
same purpose.
Neither of the above described features of this invention, viz., the edge protecting
plates nor the fold uniting rivets, are limited to belts made by folding a strip of
fabric, as they may be used with belts of any other suitable construction, as shown
in Figure 13.
Wire staples may be inserted in the edge of the belt and forms the wearing
surfaces, the said staples being formed as shown in Figure 14, and secured by having
their prongs turned or clinched within the belt, as shown by dotted lines in Figure 13.
In using these staples it is preferable to apply two or more rows to each edge of
the belt if the staples extend longitudinally of the belt or if preferred the staples may
be placed crosswise of the ridges of the belt.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, as communicated to me
by my foreign correspondent, I declare that what 1 claim is :-
First. A machine belt having at the exterior of each edge a row or series of
projecting metallic wearing pieces thereby arranged and each attached to the belt
independently of the others, the said pieces protecting the outer surfaces of the belt
at its edges against wear or abrasion, as set forth.
Second. A machine belt having at the exterior of each edge a row or series of

page_text: rivets, each attached to the belt independently of the others, the heads of said rivets
being in close proximity to each other and extending across the edges of the belt, so
as to protect said edges against wear, as set forth.
Third. A machine belt having two parallel rows of rivets, the prongs of which are
inserted and clinched in the material of the belt, while the heads of said rivets
extend across the outer surfaces of the folded edges of the belt and protect said edges
from wear.
Fourth. A machine belt having two parallel rows of rivets, presenting a row for
each edge, the prongs of which rivets are inserted and clinched in the material of the
belt, while the heads of said rivets project as described and extend across the outer
surfaces of the folded edges of the belt and protect said edges from wear, substantially
as set forth.
