I ARTHUR CHARLES HENDERSON of 47 Museum Street Oxford Street in the
Parish of Bloomsbury and county of Middlesex Civil Engineer and Patent Agent
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN THE
METHOD OF UNITING THE ENDS OF DRIVING BELTS OR BANDS a communication
to me from abroad by Alexandre Damiens Lagrelle, mechanician of the city of
Paris in the Republic of France to be as follows:-
"
The improved method of connecting the ends of driving belts or bands is as
follows: The belts or bands are first pierced by any suitable means with oblong,
and equi-distant apertures running in parallel rows lengthways of the bands or
belts. The ends of these which are to be united are then bent up vertically and
externally in such a position as to bring the apertures in the belt or band imme-
diately opposite each other, through these apertures are then passed flat metal
links, which may be of various forms provided they leave openings at each end
which extend beyond the ends to be united. Through these openings flat spring
bars or bands are passed, which firmly bolt the ends of the bands together.
These links may be either flat metal pieces, pierced at each end with oblong
openings or they may be simply long open links, or they may be rounded at the
ends with circular openings therein, in this latter case the spring bands must be
round. Or one of these bands or fasteners need not be elastic and may be furnished
with projecting arms whose ends are pierced with holes for the reception of the
second or spring bar or fastener.
By this method of uniting the ends of driving belts or bands, a few seconds only
suffices to either shorten or lengthen the bands as may be required; by the removal
of the connections..

I ARTHUR CHARLES HENDERSON of 47 Museum Street Oxford Street in the
Parish of Bloomsbury and county of Middlesex Civil Engineer and Patent Agent
do hereby declare the nature of the said invention for IMPROVEMENTS IN THE
METHOD OF UNITING THE ENDS OF DRIVING BELTS OR BANDS a communication
to me from abroad by Alexandre Damiens Lagrelle mechanician of the city of
Paris in the Republic of France and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement :-
In most of the methods of connecting or uniting the ends of driving belts or
bands with metal attachments, such for instance as the "Scellos" principle, much
time and labour is occasioned in shortening or lengthening the bands, as these
systems do not admit of piercing the holes for making the connections beforehand.
In some important industries, sugar factories for example the time occupied
is highly prejudicial, as it is detrimental in such factories to arrest operations.
The improved method of connecting the bands, which forms the subject of the
present invention, obviates these drawbacks, and is as follows.
•
The belts or bands are first pierced-by any suitable means with oblong and
equi distant apertures, running in parallel rows lengthways of the bands or belts,
the ends to be united are then bent up vertically and, externally in such a position
as to bring the apertures in the belt or band immediately opposite each other.
Through these apertures are then passed flat metal links which may be of various
forms provided they leave openings at each end.
i
These links may be simply long open links or rings, or metal pieces with rounded
ends in which are circular openings through which round or flat forked springs are
inserted, which as it were bolt the parts of the band or belt together firmly.
By this method of uniting the ends of the belts or bands a few seconds only is
occupied in shortening or lengthening them, without the aid of special tools or an
experienced workman.
Figs 1 and 2 of the accompanying drawings are a front view and a longitudinal
section showing the improved method of connection.
Fig 3 shows two views of the spring fork used in conjunction with the link
piece Fig 4.
:
Figs 5 and 6 show a slight modification of the same principle.
The ends a. b, of the band to be united are pierced with a certain number of
rows of oblong apertures c. c. as already described. The two ends of this band are
then bent up so as to bring the apertures opposite each other, and one or other of
the links is passed through these apertures, and then the spring forks h. h¹ are
inserted. In Fig 1 either the links d Fig 7 are used, or those 'f, Fig 4. These
links and their apertures are struck out at one'and the same time by any suitable
apparatus.
:
The spring fastenings may be slightly rounded externally as shown in the
drawings h. h', or may be of any other suitable form. In Figs 5 and 6 one of these
bolting springs h, is provided with projections l. l. l. in place of the links d. or f.
and these projections are pierced at their ends with openings for the reception of
the bolting piece k. with projections k¹.
Fig 8 is merely another form of link with openings f¹. f¹. in this case the bolting
spring used is also round.
•
It is evident that any form of link will serve the purpose provided there are
apertures at its ends for the reception of bolting springs of the type shown in the
drawings, or of any other suitable shape.

page_text: Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is
1st The method of connecting the ends of driving belts or bands by first piercing
them with a number of apertures of an oblong form c. The object being to insert
therein the link or the links shown by the Figures 4. 8. and 7 in the ends of
which fare circular or other shaped openings for the reception of the spring
bolts h. h¹ Fig 3.
2nd The bolting piece k Fig 5 with projections, which piece is passed through
openings made at the ends of the projections l. l. 1 of the piece h.
The whole as and for the purposes herein described and as illustrated by the
accompanying drawings.
