Improvements in and relating to Belt, Strap, or Band Fasteners.
A communication from ROBERT PAUL WELDE, of Deuben, near Dresden, and CARL
ROBERT WELDE, of Koenigstein-Elbe, both in the Empire of Germany.
I, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex,
M.L.M.E., 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 :-
The object of this invention is to enable the ends of driving belts or bands and the
like to be connected in a rapid easy and secure manner without making any holes in
the strap or damaging the same in any way, and so that the disconnection of the
belts may also be effected readily-which it will be remembered is sometimes
necessary for instance when the belt is stretched and requires tightening or
shortening.
In the accompanying drawings fig. 1 is a longitudinal section of two strap-ends
connected by this improved device. Fig. 2 is a cross section and Fig. 3 a top-
view.
The connecting device consists of a rectangular ring or link R made of the desired
strength and closed on all sides; of a three-sided prismatic wedge K made preferably
of wood the two contact surfaces of which are provided with fastening pins S and to
the third i.e. external face of which a spring clamp H is to be secured.
The mode of application and operation of this belt connecting device will be readily
understood from inspection of the drawing. A ring or link R is passed over both the
strap ends to be connected after which they are bent outwardly in opposite directions
as shown. A wedge K is then inserted between them the fastening pins thereon are
driven into the leather of the belt, and lastly the elastic protecting plate is screwed
over the whole thus completing the fastening.
The advantages derived from this arrangement may be summed up as follows ;-
The connecting operation is most simple and can be performed by any workman in
a minimum of time.
The strap or belt may be stretched to the utmost extent without any risk of the
fastening coming undone.
The belt is sufficiently protected from damage.
It may be readily unfastened in case of stretching.
The repairing of belts by means of rivets, screws &c. or by stitching is practically
avoided.
And, inasmuch as the belt-ends do not overlap, swellings and consequent inter-
ruptions of adhesion or friction between the belt and the pulley &c. are prevented ;
while uniform elasticity and smooth noiseless operation are ensured.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me
by my foreign correspondent, I declare that what I claim is :-
1. An improved device for connecting the ends of driving belts straps and the like
mainly consisting of a rectangular ring or link such as R closed on all sides, a wedge
such as K adapted to be interposed between the projecting ends of the belt and
provided with suitable fastening pins and of a clamp or plate such as H screwed over
the whole and protecting the fastening by spring action.

page_text: 2. In a belt fastening the combination with a link such as R of a wedge K to which
the ends of the belt or belts are secured substantially as described and illustrated in
figure of the accompanying drawings.
