COMPLETE SPECIFICATION.
A Hand Tool for use in Driving Bifurcated Rivets or Two Pronged
Fastenings or Staples into Leather Belting or other substances.
I, SAMUEL CLELAND DAVIDSON of Sirocco 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 invention consists of a hand tool, hereinafter called a holder, for use in
driving the bifurcated rivets or two pronged fastenings or staples made as described
in my prior Specification No. 5215 of 1892 into leather belting or other
substances.
It is of importance when driving these bifurcated rivets or staples into leather
belting or such substances that they should penetrate into the same quite per-
pendicularly to the surface, in order that when the points emerge through the
underside and strike against the smooth metal or other hard surface upon which the
belting &c. should be laid when these rivets are being driven into same, the points
may be turned by it outwards and upwards and properly re-enter the leather and
bury themselves therein in a truly upward direction; which they do not so
satisfactorily accomplish if they are not driven quite perpendicularly through the
leather &c., and the object of my invention is to so hold the rivet while it is being
hammered into and through the leather belting or other substance that it must
necessarily penetrate same perpendicularly to the surface.
My holder consists of a metal plate or bar of a shape and size adapted for its
being conveniently held by the hand and having either at one end or at each end a
Hat part through which a hole is punched or formed to the exact shape of the
outside of the rivets with which the holder is to be used. The hole forms a tight
fit endwise for the rivet, so that when the rivet is inserted head first and its points
pushed up into the hole they are slightly drawn together and the rivet thereby
firmly held in the holder. When the holder has a flat part at each end the holes
in the two flat parts may either be of the same size and gauge so as to receive and
hold the same size and gauge of rivets or of different sizes so as to receive and hold
rivets of different sizes and gauges. In some cases I make several holes in the
same flat part, and these holes may be of different sizes to receive varying sizes and
gauges of rivets.
In such cases the several holes may either be arranged one in
front of another crosswise or otherwise to the line of the holder, or one at the side
of another, or two holes may be made to cross each other in which case the centres
of both holes could be in the centre of the flat end.
Figure 1 of the accompanying drawings is a plan or top view of a holder con-
structed according to my invention with a flat part b at each end of the bar or
handle a, each flat part being formed with one hole or slot c in the centre
of same.
Figure 2 is a side view of the same holder with the flat parts bb in section and
showing a rivet d placed in one of the holes c and the flat end of the holder laid
upon the upper surface of two pieces of leather or other substance e f with a rivet
in position therein ready to be driven into these pieces.
Figure 3 shows the same parts with the rivet driven in as far as the thickness of
the holder will permit of its being driven with a hammer. The holder is then
lifted off the rivet, as the perpendicular position of the rivet in the belting is then
secure and its points (if the rivet be of sufficient length) will have commenced to
turn outwards and upwards in the leather and its driving home may then be
completed with the hammer alone and the points will continue the direction of their

page_text: outward and upward curve forming the double-clinch upon under surface of the
belting &c. as shewn in Figure 4.
Figure 5 shows a holder with three holes of different size, one in front of another
in the flat end b.
Figure 6 shows a holder with two holes of different size in the flat end 6 but
placed across each other so that the centre of both is in the centre of the flat end.
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 hand tool for use in driving bifurcated rivets or two pronged fastenings or
staples into leather belting or other substances, consisting of a handle, plate or bar
having at one or both ends a flat part in which are one or more holes or slots of the
same shape and size as the outside of the rivets, fastenings or staples, and adapted
to receive a rivet, fastening or staple and to firmly hold same perpendicularly to the
surface of the belting or other substance upon which the flat end of the holder is
laid while the rivet is being driven, substantially as hereinbefore described and
represented in the accompanying drawings.
Dated this 13th day of March 1893.
