LETTERS PATENT to Charles Denton Abel of No 28 Southampton Buildings,

PROVISIONAL SPECIFICATION left by the said Charles Denton Abel at
the Office of the Commissioners of Patents on the 6th February 1883.
CHARLES DENTON ABEL of No 28 Southampton Buildings, Chancery Lane, in
the county of Middlesex "IMPROVEMENTS IN BELT FASTENERS [communicated
to him from abroad by Peter Thacher of the city of Cleveland, county of
Cuyahoga, Ohio, United States of America.]
This invention relates to Belt fasteners, and more particularly to that class
having a plate to which are attached teeth or series of teeth adapted to pass
through the belt and be clinched upon the opposite side; and it consists in an
improved tooth and also in parts and combinations of parts, as will more fully
hereinafter appear.
In the drawings, Fig. 1 is a view in perspective of a of a belt fastener constructed
according to this invention Fig. 2 is a view of the same with one side attached to
the end of the belt C as adapted for use. Fig. 3 is a view in front elevation of a
tooth made in accordance with this invention. Fig 4 is an end view of the same
tooth. Fig. 5 is a view in cross section of a tooth constructed according to this
invention at its point of contact with the plate. Fig. 6 is a view in cross-section,
of a tooth on the line x y of Fig. 3.
In the said drawings, A represents a plate preferably made of metal, having
upon its two opposite edges one or more rows of teeth, B. These teeth may be
continued indefinitely across the face of the plate. As shewn in figs. 3, 4, 5 and 6
of the drawings, the improved tooth is formed preferably of cylindrical or elliptical
shape at its base, gradually tapering towards its point, the inner face of the tooth
being somewhat flattened, it being found that this construction of tooth is less
likely to split the leather, as it passes through it; also, the point presents two

page_text: oppo te flat surfaces, which make it easy to drive the same through the leather,
and also make it easy to be clinched.
In speaking of the "width" of the plate, I mean by that the direction across the
plate in which the tractive action of the belt is exerted upon the plate in use, and
the direction across the plate, at right angles with such width, is spoken of herein
as the length of the plate.
This belt fastener is constructed preferably of malleable iron, the width of the
plate varying with the width of the belt to which it is proposed to attach it, and
the length of the teeth varying as the thickness of the belt. The use of this plate
is indicated by fig. 2 of the drawing, in which is shewn the plate attached to the
end of a belt C, with the points turned or clinched upon the belt.
Fig. 7 is a view in cross section of the Belt-fastener with one tooth clinched,
shewing the manner of clinching the teeth.

CHARLES DENTON ABEL of N° 28 Southampton Buildings Chancery Lane in
the County of Middlesex "IMPROVEMENTS IN BELT FASTENERS A communi-
cation to me from Abroad by Peter Thacher of the City of Cleveland, County of
Curfahoga, Ohio, United States of America.
This invention relates to belt fasteners, and more particularly to that class
having a plate to which are attached teeth adapted to pass through the belt
and be clinched upon the opposite side; and it consists in an improved tooth and
also in parts and combination of parts, as will more fully hereinafter appear.
In the drawings, Fig. 1 is a view in perspective of a belt fastener constructed
according to this invention; Fig. 2 is a view of the same with one side attached
to the end of the belt O as adapted for use, Fig. 3 is a view in front elevation of a
tooth made in accordance with this invention. Fig. 4 is an end view of the same
tooth. Fig. 5 is a view in cross section of a tooth constructed according to this
invention at its point of contact with the plate. Fig. 6 is a view in cross section
of a tooth on the line x y of Fig. 3.
In the said Drawings, A. represents a plate preferably made of metal, having
upon its two opposite edges one or more rows of teeth B. These teeth may be
continued indefinitely across the face of the plate. As shewn in Figs. 3, 4, 5 and 6
of the drawings, the improved tooth is formed preferably of cylindrical or elliptical
shape at its base, gradually tapering towards its point, the inner face of the tooth
being somewhat flattened, it being found that this construction of tooth is less
likely to split the leather as it passes through it; also, the point presents two
opposite flat surfaces, which make it easy to drive the same through the leather,
and also make it easy to be clinched.
This belt fastener is constructed preferably of malleable iron, the width of the
plate varying with the width of the belt to which it is proposed to attach it, and
the length of the teeth varying as the thickness of the belt. The use of this plate
is indicated by Fig. 2 of the Drawing, in which is shewn the plate attached to the
end of a belt C with the points turned or clinched upon the belt.
Fig. 7 is a view in cross section of the belt fastener with one tooth clinched,
shewing the manner of clinching the teeth.
Having thus described the nature of this invention and in what manner the
same is to be performed as communicated to me by my foreign correspondent, I
claim The construction and use of a belt fastener consisting of a plate with
projecting teeth, each of elliptical section at its base and tapering to a point having
two flat sides, substantially as herein described.
In witness whereof I the said Charles Denton Abel have hereunto set my
band and seal this twenty third day of May in the year of our Lord One
thousand eight hundred and eighty-three.
