Improvements in Belt Fasteners.
A communication to me from abroad by WILLIAM MASON WHITING, of Orange,
in the State of New Jersey, United States of America, Manufacturer.
I, FRANK REDDAWAY, of Cheltenham Street, Pendleton, Manchester, England,
Manufacturer of Machine Belting, 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 and accompanying drawings:
The object of this invention to strengthen the fastening between the ends of a
leather or other belt and at the same time to render such fastening flexible and not
liable to slip upon the pulley. Metallic plates have been made use of, secured by
rivets to the ends of the belt, and also metallic strips have been extended from one
end to the other of the belt and been bent around and clinched in the form of
hooks, and in some instances lapping plates have been applied over the joint..
This invention relates to the peculiarities of construction and combination
hereinafter set forth and claimed.
In the drawings,
Fig. 1 is a plan view of the belt with the improvement applied thereon.
Fig. 2 shows the reverse side of the belt, and
Fig. 3 is a section at the line xx.
The belt A is to be either of leather or woven material, and upon one side of
the belt the spring-plates B, extending across from one part of the belt to the
other are made use of, and these spring plates are to be sufficiently numerous to
afford a strength equal, or nearly so, to the tensile strength of the belt, and these
plates are preferably of tempered steel, so that they will yield in passing around
the pulley. The plates are to be applied at the inner or pulley side of the belt,
and the bolts C pass through these plates and through the belt and are provided
with nuts or rivet heads at the opposite side of the belt.
Plates have heretofore been employed upon the outer side of the belt, the
rivet-heads and nuts extending above the same. In consequence of applying
these plates at the pulley side of the belt the sheet metal is to be struck up in the
form of conical recesses around the bolt-holes, as seen at 2, so that the bolt-heads
do not project, and the metal of these conical recesses is embedded into the belt
and aids in firmly clamping the same. At the opposite side of the belt a lap of
leather or similar material is applied at D, the same being sufficiently large for
the bolts C to pass through the same, and this lap being of leather, raw-hide, or
similar material is flexible and slightly elastic, so that the strength of the fastening
is augmented without the belt being rendered too rigid at the joint, and with
woven belts especially it is advantageous to apply the transverse spring plates E,
resting upon the lap D and between the same and the nuts 4 of the bolts C, such
transverse spring-plates being perforated for the passage of the bolts.
By this construction a very firm belt fastening is made, possessing the requisite
elasticity and strength, and the risk of slipping upon the pulley is reduced to a
minimum, because the spring plates B become embedded, or nearly so, into the
underside of the belt.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :
1st. The combination, in a belt fastening, with the screw bolts having conical
heads and passing through the belt into nuts at the other side, of metallic spring-
plates, each plate having holes near the ends with the adjacent metal stamped up

page_text: conically to receive and contain the conical bolt-heads, whereby the metallic
connections of the belt are adapted to be embedded into the material of the belt,
substantially as set forth.
2nd. The combination in a belt fastening, of spring-plates extending across
from one end of the belt to the other and having countersunk recesses, bolts
passing through the spring-plates and through the belt-and having heads within the
recesses, a lap of leather on the outer surface of the belt and through which the
bolts pass, transverse spring-plates upon the surface of the lap and through which
the bolts pass, and nuts for clamping the parts, substantially as set forth.
3rd. The combination, in a belt fastening, of metallic spring-plates having holes
near the ends with the adjoining metal stamped up to form conical recesses, screw-
bolts with conical heads fitting the recesses, a lap of leather or similar material for
the outer side of the belt and covering the joint, the bolts passing through the
belts and through the lap, and nuts for clamping the parts firmly together, sub-
stantially as set forth.
