A New or Improved Belt Fastener and Belt Perforator.
I, PHILIBERT LOISON-PROST, of Génelard in the Republic of France; Engineer, do
hereby declare the nature of this invention to be as follows:-
My invention relates to a new or improved belt fastener and also to a new or
improved belt perforator the latter of which may conveniently be employed to
perforate the belt which is to be fastened by the former.
The fastener consists of two separate parts which I distinguish as the frame and
the pin. To form the frame I stamp out of sheet metal or cast a piece of the
form shown in figure 1 of the accompanying drawings. This piece I then bend upon
itself in such manner as to form a frame as shown in figure 2 in which it will
be seen that an oval hole is left at the end of each branch of the said frame.
The pin, which is of steel or any other convenient metal, is constructed of the
form shown in figure 3.
To use my fastener all that is necessary is to perforate the ends of the belt
with holes for the passage of the branches of the frame, bring the said ends of
the belt together, pass the branches through the holes, slide the pin through the
oval holes at the ends of these branches, and then give the said pin a half turn
so as to prevent the possibility of its slipping out. The belt is now fastened up
as shown in figure 4.
In the several figures mentioned I have shown the frame as having three
branches. It will be understood however that the number of branches should
vary with the width of the belt it being most convenient to employ a single
fastener extending the whole breadth or nearly so of the belt.
If the belt be suitably perforated beforehand a workman can very quickly and
easily tighten it up without special tools.
In order to rapidly and effectively unite the ends of belts by such fasteners it
is important that the holes pierced should be equidistant and that they should be
made with accuracy and without any groping about for their proper positions.
For this purpose I have invented a perforator with special guiding arrange-
ments. Figure 5 is a view of this perforator in its open position and placed
beside the end of a belt perforated by its means. Figure 6 shows the perforator
closed upon the end of a belt.
The cutter or punch a is the same as in the ordinary tools of this kind. b is
a small distance-pin of such size that it easily enters the holes cut by a, and
which when inserted in the last hole cut ensures the next hole being cut at the
proper distance therefrom. c is a shoulder or guide against which the extremity
of the belt bears and which ensures the row of holes being in line and equi-
distant from the extremity. d is the belt itself.
When desired I may make the positions of b and c adjustable with respect to a
so that an alteration of the distance of the holes from one another and from the
extremity of the belt may be obtained.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that
what I claim is
1. The new or improved belt fastener consisting of a frame and a pin substan-
