PROVISIONAL SPECIFICATION.
Improved Fasteners for Driving Bands and Belts.
'I FRANK TYRREL LONG of 26 Southfields Road, Wandsworth in the
County of Surrey, Clerk, do hereby declare the nature of this invention to be as
follows:-
This invention relates to the manufacture and construction of a linked fastener
for driving bands and belts which constitutes an improved means of jointing the
ends of driving bands or belts so that the joint may adapt itself to and obtain a
thorough grip upon the pulley without any undue strain being put upon either the
fastener or the ends of the band or belt.
It is composed of arched or dome shaped plates which are joined together
by means of a connecting link. The plates are cast with knuckles on the
fastening side at sufficient distance apart to allow the connecting link to work
between them.
The link is joined to the plates by means of pins or pivots which pass through
holes cast or drilled in the knuckles of the plates and in each end of the link
the pins or pivots are made fast in the knuckles of the plates and work in the
holes in the links.
The links are cast of sufficient size to allow the joint to adapt itself to and
obtain a thorough grip upon the pulley.
The extreme ends of the link are cast with a projection, or lug which overlap
the plates between the knuckles and ensure a perfectly straight pull between the
pulleys which prevents the joint from dipping and lessens the strain upon the
heads of the bolts which connect the plates with the band or belt. The plates
are hollowed or dished on the undersides and permit the heads of the bolts to be
drawn up out of contact with the pulley. Each plate is cast with a bolt hole in
the centre and a large tapeheaded bolt is used with small teeth on the inside of
the head to engage the belt when screwing up.

COMPLETE SPECIFICATION.
Improved Fasteners for Driving Bands and Belts.
I, FRANK TYRREL LONG, of 26 Southfields Road, Wandsworth, in the
County of Surrey, Clerk, 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 the manufacture and construction of a linked fastener
for driving bands and belts, which constitutes an improved means of joining the
ends of driving bands or belts so that the joint may adapt itself to, and obtain a
thorough grip upon, the pulley without any undue strain being put upon either the
fastener or the ends of the band or belt.
My invention is illustrated in the accompanying drawings, in which :-
Fig. 1 is an edge view and Fig. 2 is a plan of my improved belt fastener.
Figs. 3 and 4 are respectively an edge view and an underside view of the
intermediate connecting link, and
Fig. 5 is an underside view of one of the arched end plates separately.
Fig. 6 is an edge view showing two ends of a belt or band connected together
by my improved fastener, &
Fig. 7 is a cross section drawn on the line 1. 1. of Fiø. 6.

page_text: My improved belt or band fastener consists of two transversely arched
plates a a, which are joined together by means of a connecting link b. The
plates a a are each formed with knuckles a' a' on their outer sides at a sufficient
distance apart to allow the connecting link to work between them. The con-
necting link is connected to the plates a a by means of pins c which pass through
holes formed in the knuckles a' a' of the plates aa and in each end of the link &
The pins are made fast in the knuckles a' a' of the plates a a and work freely in
the holes in the link b. The links are made of sufficient size to allow the joint
to adapt itself to, and obtain a thorough grip upon, the pulleys. The extreme
ends of the link bare each formed with a projection or lug b', which projections or
lugs overlap the plates a a beyond the knuckles a' a¹ and ensure a perfectly straight
pull between the pulleys, which prevents the joint from dipping and thereby
lessens the strain upon the heads of the bolts d which connect the plates a a with
the band or belt e. The plates a a are hollowed or arched transversely on their
undersides as shown at Figs. 1, 5 and 6, and thereby permit the heads of the
bolts d to be drawn up out of contact with the pulleys. Each plate a a is formed
with a bolt hole a in the centre and a bolt d with a long head d' is used, which
head is tapered or curved on its inner face and is there provided with small
teeth to engage in the belt e when the bolt d is being screwed up by the nut f.
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. A linked belt or band fastener constructed substantially as herein shown
and described.
2. A. linked belt or band fastener constructed of two transversely arched plates,
connected together by a connecting link hinged thereto, and having each a bolt
hole through which a bolt is passed which is provided with a long head tapered or
rounded on the inner side and formed with small teeth, substantially as herein
shown and described, and for the purpose stated.
3. In a linked belt or band fastener, the combination of two transversely arched
plates, a connecting link hinged at each end to such plates, a lug or projection at
each end of such link bearing upon the outside of the plates, a bolt hole through
each plate, and a bolt passed through each of such holes and having a long head
tapered or rounded on its inner face and provided with small teeth, substantially as
herein shown and described and for the purpose stated.
