Improvements in Fasteners for Bands and Belts. .
I, WILHELM STEFAN HEINRICH SCHMIDT of 15 Hagenerstrasse, Iserlohn,
in the Kingdom of Prussia and German Empire, Manufacturer, 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:-
This invention relates to fasteners for driving belts, military belts, traces, stirrup
leathers, bands, straps and the like, its object being the construction of a simple
form of fastener which cannot readily become loosened by accident.
The accompanying drawings illustrate in what manner I may carry my invention
into practical effect and will hereinafter be referred to.
Figure 1 is a vertical longitudinal section, and
Figure 2 a plan of the fastener as applied to a belt.
Figure 3 is a vertical longitudinal section of the fastener with the ends of the belt
removed therefrom, and
Figure 4 is a plan of Figure 3.
The fastener consists essentially of a rectangular frame a constructed of steel or
of any metal possessing the requisite strength. This frame has a greater length
than breadth and in the narrower sides there is mounted excentrically a roller b,
nearer to one of the longer sides than to the other. The periphery of this roller is
grooved or serrated to enable it to obtain a better grip upon the substance of the
band or belt.
On the inner side of the frame which is more distant from the roller b, there is
formed a projection c, or there may be two or more such projections if desired, and
in one end of the band or belt d there is or are formed a hole or holes to fit and
correspond with the projection or projections c.
In applying the fastener, the perforated end d of the belt is engaged with the
projection or projections (Figures 1 and 2) and the other end e is passed up
between the projection c and the roller b, over the roller, and down between it and
the nearer side of the frame. The roller is then turned, either by partly with-
drawing the end e of the belt or otherwise, until it assumes the position indicated by
Figure 1, when the two ends of the belt will be firmly gripped between the roller
and the more distant side of the frame, and any pull exerted upon the belt will tend
only to grip the ends more firmly in the fastener.
The belt may be readily released, by loosening it and turning the roller in the
opposite direction.
The fastener constructed as hereinbefore described is especially applicable for
use with driving belts, and particularly in the case of electric installations, since it
does not come into contact with the pulleys and has no projecting part on the inner
face.
If such a fastener be required to run through a strap fork or against a guide or
the like, it may be made of a total length equal to or a little less than the width of
the belt, and the ends of the belt be reduced in width to fit the fastener.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is―
1. In a fastener for connecting the ends of bands belts straps and the like, the
combination and arrangement in and with a rectangular frame, of an excentric
roller mounted near to and parallel with one side of the frame, and a projection or
077

page_text: projections on the inner face of the opposite side of the frame, substantially as
hereinbefore described and as illustrated by the accompanying drawings.
2. A fastener or buckle for bands belts straps and the like, constructed sub-
stantially as hereinbefore described and as illustrated by the accompanying
drawings.
Dated this 28th day of April A.D. 1893.
