the Commissioners of Patents on the 8th July 1878.
HENRY SIMON, of No. 7, St. Peter's Square, Manchester, in the County of
Lancaster. "IMPROVED MEANS FOR JOINING DRIVING BELTS FOR MACHINERY."
[A communication from abroad by Peter Jorissen, of Soest, in the German Empire.]
According to the present Invention the turned up ends of a driving belt are
nipped between two narrow metal plates having serrated faces which are pressed
against the outer faces of the leather by means of a screw which passes through a
hole in the one plate, and through the two ends of the leather and screws into a
threaded hole in the other plate; or it may also pass loosely through the second
plate and be provided with a nut outside it.
To enable the belt to be tightened up readily from time to time, the hole of the
one end through which the screw passes is by preference slotted, so that such end
may be tightened up after slacking the screw sufficiently to allow the end of the
belt to pass loosely between the plate and the other end of the leather. Or one or
both ends may be provided with a series of holes for the above purpose, which
arrangement would, however, require the screw to be entirely withdrawn from the
nipping plates when the belt is to be tightened.
For broad belts the ends may be secured by two or more pairs of such nipping
plates and screws.

the said Henry Simon in the Great Seal Patent Office on the 8th January
1879.
HENRY SIMON, of No. 7, St. Peter's Square, Manchester, in the County of
Lancaster. "IMPROVED MEANS FOR JOINING DRIVING BELTS FOR MACHINERY."
A communication from abroad by Peter Jorissen, of Soest, in the German Empire.
That according to the present said Invention the turned up ends of a driving
belt are nipped between two narrow metal plates having serrated faces which
are pressed against the outer faces of the leather by means of a screw which passes
through a hole in the one plate and through the two ends of the leather, and screws
into a threaded hole in the other plate; or it may also pass loosely through the
second plate, and be provided with a nut outside it.
To enable the belt to be tightened up readily from time to time, the hole of the
one end through which the screw passes is by preference slotted, so that such end
may be tightened up after slacking the screw sufficiently to allow the end of the
belt to pass loosely between the plate and to the other end of the leather.
Or one
or both ends may be provided with a series of holes for the above purpose, which
arrangement would, however, require the screw to be entirely withdrawn from the
nipping plates when the belt is to be tightened.
For broad belts the ends may be secured by two or more pairs of such nipping
plates and screws.
But to enable these improvements to be better understood I will proceed to
describe the same by reference to the accompanying Drawing, in which,
Figure 1 represents a side view of a driving belt joint secured by two small
metal plates; and Figure 2, front view of the same.
Figure 3 represents a top view of the small metal plate; and Figure 4, plan
shewing serrated face.
Figure 5, side view of a driving belt joint with larger metal plates; and Figure 6,
front view of the same.
Figure 7, top view of the metal plate; and Figure 8, plan shewing serrated
.face.
Figure 9 represents a side view of a driving belt joint secured by strong metal
plates; and Figure 10, front view of the same.
Figure 11 represents a top view of the strong metal plate; and Figure 12, plan
shewing the serrated face.
Similar letters of reference are used to represent similar parts.
A shews the turned up ends of a driving belt, which are nipped between two
narrow metal plates B and C. These plates have serrated faces D which press against
the outer surface of the leather by means of the screws E; these screws pass through
holes made in the top plates B, and screw in threaded holes made in the bottom
plates C; but the plates can be tightened up by means of studs and nuts.
To readily tighten up the belts when required, the bottom holes F of the belt are
slotted, so that such end can be tightened up after slacking the screws sufficiently to
allow the belt end to pass loosely between the plates and be pulled until tightened
up, after which the nipping plates are again secured to the leather joint. Or the
bottom end of the leather can be made with a series of holes G, or the holes can be
made in both ends G and H; but the screws or studs would have to be removed
from the plates, and the nipping plates also placed over the holes required to
tighten up.
For narrow belts one set of nipping plates is used, and for broad belts sevēral
sets of nipping plates can be employed.
Having thus described the Invention as communicated to me, and the best means
I am acquainted with for carrying the same into effect, what is claimed is, the
securing of the turned up ends of driving belts for machinery by means of nipping

page_text: metal plates having serrated faces which are pressed against the outer faces of the
leather by means of screws or by studs and nuts, substantially as herein-before
described, and represented in the accompanying Drawing.
In witness whereof, I, the said Henry Simon, have hereto set my hand
and seal, this Seventh day of January, in the year of our Lord One
thousand eight hundred and seventy-nine.
HENRY SIMON. (L.S.)
