PROVISIONAL SPECIFICATION.
Improvements in Fasteners for Connecting Driving Belts.
I PIERRE LASCOUMES, 9, Fox Road, West Bridgford, Nottinghamshire,
Machinist, do hereby declare the nature of this invention to be as follows:-
Each fastener consists of a bar of brass, malleable iron, or steel, from each side
of which two or more flat pointed hooked arms project.
The ends of the belt to be connected have holes cut or otherwise formed in them
opposite to each other through which the ends of the hooked arms are passed, from
the lower side the ends of the arms resting upon the upper side of the belt. The
under side of each end of the belt is cut to a bevel and lie close to each other
resting upon the top side of the bar of the fastener.
For wide belts the bar may be made longer with a greater number of hooked
arms or a number of short fasteners may be employed.
Fasteners so formed being in one piece the ends of belts may be quickly joined
and when the belt requires shortening the fasteners may be quickly removed.

COMPLETE SPECIFICATION.
Improvements in Fasteners for Connecting Driving Belts.
I, PIERRE LASCOUMES, of No. 9 Fox Road, West Bridgford, Nottingham,
Machinist 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 invention consists of a bar of metal having two or more curved arms pro-
jecting on each side, of such a shape and construction as shown in the drawing
annexed, being all in one piece; and which is easily inserted or withdrawn from
the belt when required, is strong, and is not liable to come out of place and so
allow the ends of the belts to become uncoupled.
The fastener is used thus:-Holes having been made by cutting, punching or
other means in the ende of the belts to be connected, the curved arms are inserted
and the belts placed in position on the fastener as shown in Figure 5.
Figure 1 on the drawing is a plan of the fastener and Figure 2 an end view of
same, A. A. being the metal bar and B. B. the curved arms.
For the purpose of more clearly explaining my invention I also refer to Figure 3
which is a large end view showing the bar with curved arm and one end of belt F.
in position as in use; the dotted outline showing position of belt when the fastener
is being inserted or withdrawn.
The action of the fastener in use is as follows:-The curved arms having been
inserted in the belt ends and the belt having been passed round into position as
shown, it takes its bearing on the fastener at C. Figures and 5, the projecting
ends D. of the fastener forming a fulcrum about which the belt is bent when in use,
thereby forcing the belt more securely on the fastener and preventing any tendency
to come off the same.
It will be seen in the drawing that I make the fastener greater in section at the
curved part E. of the arms than it is at C. where the belt takes its bearing, to
prevent the belt slipping off the fastener or the fastener coming out of the belt
n
.

page_text: unless placed in the position shown by the dotted lines in Figure 3, when the
fastener can be easily inserted or withdrawn as before mentioned.
Figure 4. is a plan showing the ends of two belts connected together by the
fastener;
Figure 5. is a side view, the belt F. F. being shown in the position it assumes
when in use.
In the drawings the curved arms are shown of a square section; I however do
not necessarily confine myself to this, as they may be round or any other con-
venient section.
The fasteners are made of various sizes and strengths to suit different sizes and
thicknesses of belts..
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:-
A belt fastener consisting of a bar with curved arms, of a construction and action
substantially as shown and described.
