Agency, of Frankfort-on-the-Maine, in the Empue of Germany, for the
Invention of "IMPROVEMENTS IN THE MEANS OF AND IMPLEMENTS FOR
FASTENING TOGETHER OR UNITING THE ENDS OF BELIS" A cominunication
from Johannes Bachmann, Technical Director of the "Nuinbergei Diahtstiften-
fabuk," residing at Nuinberg, in the Empic of Germany
PROVISIONAL SPECIFICATION left by the said Frank Wirth at the Office of
the Commissioners of Patents on the 26th January 1877

FRANK WIRTH, of the Firm of Wirth & Company, Patent Agency, of Frankfort-
on-the-Maine, in the Empue of Germany "IMPROVEMENTS IN THE MEANS OF
AND IMPLEMENTS FOR FASTENING TOGETHER OR UNITING THE ENDS OF BELTS'
A communication fiom Johannes Bachmann, Technical Director of the "Nuinberger
Diahtstiften-fabrik," residing at Nuinberg, in the Empire of Germany
The improvements consist in the use of lunged fasteners constructed in two or
more pieces, so that either half or piece of such can be readily engaged with or
disengaged from the other without iemoval of the fasteners froin the belt to which
they inay be applied, and in furnishing such fasteners with pins for insertion in the
belt, such pins being rivetted after then passage through the band
Also in the
use of fasteners similar to those described, but arranged with double plates, Jaw
fashion, furnished with upper and lower teeth for the purposes of embracing and
firmly holding the belting The various parts may be made of metal or other con-
venient material.

SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Frank With in the Great Seal Patent Office on the 26th June 1877
FRANK WIRTH, of the Firm of Wuth and Company, Patent Agency, of
Frankfort-on-the-Maine, in the Empue of Germany "IMPROVEMENTS IN THE
MEANS OF AND IMPLEMENTS FOR FASTENING TOGETHER OR UNITING THE ENDS OF
BELTS" A communication from Johannes Bachmann, Technical Director of the
"Nurnberger Diahtstiften-fabrik," residing at Nurnberg, in the Empire of Germany.
The improvements consist in the use of hinged fasteners constructed in two or
more pieces, so that either half or piece of such can be readily engaged with or
disengaged from the other, without removal of the fasteners fioin the belt to which
they may be applied, and in furnishing such fasteners with pins for insertion in the
belt, such pins being vetted after their passage through the belt Also in the use
of fasteners similar to those described, but arranged with double plates, jaw fashion,
furnished with upper and lower teeth for the purposes of embracing and firmly
holding the belting
The great advantages gained by using metallic belt fasteners, over lace, are in
most cases very apparent, and consist chiefly in the saving of tune in joining belts,
saving of the lap ends which have to pass over each other when Laces are used, the
even tension gained preventing the belts from running off their pulleys
All belt fasteners yet invented have had the great drawback of having to be
attached when the belts are on theu shaftings, unless both pulleys happen to stand
fiec, so that the belt can be placed over them after having been joined When the
pulleys are high up and the joining has to be done while the shafting is running, the
danger and difficulty is greatly increased The improved belt fastener obviates all
these dangers, as the same consists of two distinct parts, each of which is fixed to
its respective belt end, the belt being then placed over the shafting and the two
parts of the fastener slided together, in which position they form a secure joint
In order to more thoroughly explain the Invention, I will proceed to describe the
accompanying Diawings, showing a convenient mode of performing the saine, in
which like letters of reference denote like parts in all the Figures
Figure 1 is a back view of the unproved belt fastener, Figures 2 and 4, side views,
and Figure 3, a front view of the same
As will be seen from the Diawing the fastener consists of two distinct parts A
and B, which are easily detached from each other by being folded over backwards
together, as shown in Figure 4, the part A being then slided longitudinally out of
the hooks D, detachment however can only be effected when the parts A and B aie
in position, as shown in Fig 4, owing to the hooks D being sufficiently bent over
towards the plate B, so that the space between their ends and the plate B is smaller
than the bar of A, round which the hooks D hold All longitudinal play or working
of the plates A and B is prevented by the hooks D passing through holes C in the
plate A The parts A and B are attached to then respective belt ends by means of
the points or nail like projections e, e, which are hammered down in the ordinary
manner
It will be seen from the foregoing that the parts A and B can be attached to the
ends of any belt when the latter is off the shafting, it can then be replaced, and
the two halves of the fastener slided into one another, when a joint is at once
secured
Figures 5, 6, 7, and 8, represent another shape of fastener, consisting of two
halves F, E, and H, G, which are held together by a central and common pin, as
shewn in Figures 7 and 8 This pin serves as a hinge, allowing the halves to be
opened, as shown in Figure S, when the belt ends can be placed between the jaws,
and the latter being closed, the teeth J, J, enter the said ends, and firmly hold the
same, Figure 5 is a top view of a belt fastener constructed according to this pait
of my Invention, Figure 6, bottom or underneath of the same, Figure 7, side
view of same closed; Figure 8, side view shown open to admit the belt ends.

page_text: It will be seen from the Diawing that the teeth J, J, are so aanged that they
pass between each other, thus the teeth of G fit between those of E, and those of
between the teeth of F
The improved belt lasteners may be made any size and of any suitable material
In witness whereof, I the said Frank Wnth, have hereunto set my hand and
seal, this Twenty-fifth day of June, in the year of our Loid One thousand
eight hundied and seventy-seven.
