COMPLETE SPECIFICATION.
Improvements in and relating to Fastening Appliances for Belting
and other Straps and Bands.
I, SAMUEL CLELAND DAVIDSON of Sirocco Engineering Works, Belfast,
Ireland, Merchant 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 :-
My improvements have reference, in part, to the forked rivets or fasteners
described in the Specification of previous Letters Patent granted to me and
dated 16th March 1892, No. 5215 (and which Specification, for brevity of
description, is hereinafter referred to as my previous Specification).
One of the objects of my hereinafter described invention is to more effectually
prevent the heads of the said forked rivets, when driven hard home, from
penetrating too far. into the material of the belting or other strap or band fastened
by them, and thereby so weakening it that the head of the rivet may pull through
the weakened portion, when subjected to an extra strain; and for this purpose one
part of my present invention consists in the employment with said rivets of washers
or plates, in which are perforations to correspond with the cross section of the two
prongs of each rivet employed therewith, so that when the two prongs of the rivet
are driven through their corresponding perforations, the intervening part of the
washer or plate between them, prevents the head from passing through, and
distributes the tightening grip of the rivet over the whole surface of the washer
or plate, and over a large surface of the material being fastened. They also
prevent detrimental indentation thereof, even when the rivet is hard driven at the
finish, and which hard driving, instead of doing harm as formerly, now gives the
rivet, with this arrangement or device, a firmer and stronger hold of the material;
and another object of my hereinafter described improvements is to further utilise
and employ the said forked rivets for attaching, to the leather or other material of
belting or other straps and bands connecting or jointing plates of thin metal, the
flat plates or flaps of hinges, buttons &c., by having the same similarly perforated
in suitable places to let the prongs of the rivets pass through them, in same way as
through the washers or plates above referred to.
Reference to the accompanying drawings will more fully illustrate the nature of
my invention, and how same is carried into effect. The same letters of reference
indicate corresponding parts in each figure.
Figures 1 and 1 are a plan and a section respectively of a flat circular washer
or plate A A with perforations C C near the centre of same corresponding with,
and through which the prongs or legs of the forked rivet described in my previous
Specification, are driven.
Figures 1, 1, 1, 15,17 are views shewing the employment with forked rivets BB
of the flat circular washer A A in making two different forms of joint in a belt or
strap EE, DD in Figures 18, 1° and 10 is a leather jointing piece or back strap.
Figures 2 and 24 are a plan and a section respectively of a flat, square or
rectangular jointing plate A A with perforations C Ċ through which the prongs of
said forked rivets are driven.
Figures 2B, 20, 2 are views shewing this jointing plate A A fixed to either end of
a belt or strap E E by means of forked rivets B B.
Figures 3 and 34 are a plan and a section respectively of a flat square, or
rectangular jointing plate A A with several perforations Ċ C on each side and
ro

page_text: arranged slightly diagonally on plate, to allow the points of the rivets to pass one
another when driven.
Figures 3, 3 and 3D are views of the last mentioned jointing plate A A employed
in the making of a joint or connecting the ends of a belt E E by use of same with
a row of forked rivets BB along two of the sides or edges.
Figures 4 and 44 are views shewing plates A A, for jointing belting straps or
bands and which are constructed in the form of a hinge, so as to bend to the shape
of a pulley, when employed in connecting the ends of a belt used for driving
machinery. These plates are each double and bent over a pin forming a hinge aš
shown, a split pin H being preferably employed with the hinge, on account of the
facility with which it can be removed out of the hinge when the plates A A. require
to be disconnected from each other.
Figures 4 and 4" show these hinged jointing plates A. A fixed to the ends of a
belt E E by means of forked rivets B B.
Figures 5 and 5 show views of another type of hinged jointing plates A A
which possess the same advantage as those shown in Figure 4 being constructed so
as to bend when passing over a pulley, with the additional advantage that they can
be most readily attached or detached at any time, when the belt is thrown off the
pulley, by one plate being first folded over on to the other to a certain position,
the two plates being then moved sideways in opposite directions, so that the
pins H H of the one, slide out of the sockets G G of the other.
Figures 5 and 5" show these hinged detachable jointing plates AA attached to
the ends of a belt or strap E E by means of forked rivets B B, and the ends of
such belt or strap EE connected or coupled by the employment of the said
detachable jointing plates A A.
Figure 5B is a view showing the method of attaching or detaching the plates A A.
The plates are shown folded over on to each other to the correct position for
detaching or attaching.
Figures 6 and 6 are a plan and a section respectively of a fastening device for
belting straps or bands in the form of a dished plate or button A with holes or
perforations CC near the centre of same to correspond with the prongs or legs of
a forked rivet.
Figures 6B, 60 and 6" are views showing the dished plate A fixed to the end of a
piece of strap or leather belt E by means of a forked rivet B, and also showing
how another end of strap or leather belt E may be attached to that upon which
the plate is fixed, by having a slit or button-hole K near the end of it as shown in
Figure 6 and same opened and passed over and under the flanges of the dished
plate or button A, as indicated in Figure 6.
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 [
claim in respect of "Improvements in and relating to fastening appliances for
belting and other straps and bands " is :-
1. The combination with the forked rivets described in my previous Specification,
of plates or washers with perforations to correspond with the cross section of the
two prongs of each rivet employed therewith, all substantially as and for the
purposes herein before described and represented in the accompanying drawings.
2. The fastening for belting straps or bands hereinbefore described and represented
in Figures 4, 4, 4B, and 40, of the accompanying drawings, in which the plates
referred to in Claim 1 are joined together in pairs as hinges and attached by the
rivets described in my previous Specification, to the ends of straps or belting,
substantially as hereinbefore described and shown.
3. The fastening for belting, straps or bands shewn in Figures 5, 5, 5º, 5º, and 5"
in which the plates referred to in Claim 1 form a hinge which enables the belt to bend
in passing over a pulley and which when the belt is off the pulley is capable of
being attached or detached by being first folded over or closed upon itself to either
one side or the other, and by the pin of the one plate being then made to slide to

page_text: one side out of the sockets of the other plate, substantially as hereinbefore
described and shown.
4. The fastening for belting, straps or bands shown in Figures 6, 6ª, 6º, 6º and 6º
in which the plate referred to in Claim 1 is in the form of a dished plate or button
secured by a forked rivet to the end of a piece of strap or leather belt and
adapted to engage with a buttonhole or slit such as shown in Figure 6 near the
end of another piece of strap or belt substantially as hereinbefore described and
shown.
