Improvements in or Applicable to Machines for Securing Tubular
Rivets, Eyelets, and the like.
I CHARLES LITOHFIELD, of 17 Cannon Street, Wellingborough, in the county of
Northampton, Bicycle Manufacturer do hereby declare the nature of this invention to
be as follows:-
This invention relates to the construction and application to a suitable press of a
swinging spring jaw arrangement whereby ordinary tubular rivets can be applied for
connecting together parts of the uppers of boots and shoes, the ends of driving bands,
harness work, and for other purposes where tubular rivets are used.
The said swinging spring jaw arrangement is hinged to any suitable part of the
press which will allow of it being moved in a horizontal plane so as to bring the jaws
(provided with a suitable recess to receive the rivet) between the punch and the die of
the press. The punch is of a tapered form so that as it is brought down by the press
it opens the jaws and forces the rivet through the material to which the rivet is to be
applied, the lower end of the rivet being upset by the die in the usual manner.
By this arrangement the rivets can be applied in an expeditious and simple manner
the arrangement also allowing of the rivets being applied accurately in the places
required.

page_text: I CHARLES LITCHFIELD, of 17 Cannon Street Wellingborough, in the county of
Northampton, Bicycle Manufacturer, 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 construction and application to a suitable press of a
swinging spring jaw arrangement whereby ordinary tubular rivets can be applied for
connecting together parts of the uppers of boots and shoes, the ends of driving bands,
harness work, and for other purposes where tubular rivets are used.
The said swinging spring jaw arrangement is hinged to any suitable part of the
press which will allow of it being moved in a horizontal plane so as to bring the jaws
(provided with a suitable recess to receive the rivet) between the punch and the die of
the press and clear away from the same. The punch is of a tapered form so that as it
is brought down by the press it opens the jaws and forces the rivet through the
material to which the rivet is to be applied, the lower end of the rivet being upset by
the die in the usual manner.
In order to enable my invention to be fully understood I will proceed to describe
the same by reference to the accompanying drawings in which figure 1 represents a
side elevation of an ordinary machine for securing rivets, eyelets, and the like with my
improvements applied thereto, the parts being shewn in their normal position; figure 2
is a horizontal section on line A, B, of figure 1; figure 3 is a similar view to figure 2
but shewing the parts in the position they occupy when forcing a tubular rivet through
two pieces of material; figure 4 is a plan of the swinging spring jaw and bracket for
attaching it to a press; figure 5 is an elevation of an ordinary tubular rivet. Similar
letters in all the figures represent similar parts.
A, represents my swinging spring jaw which is hinged to a bracket B, on the
press a, which is of ordinary construction; the spring jaw A, by this means can be
moved in a horizontal plane from the position shewn in full lines to that shewn in
dotted lines in figure 2 for the purpose hereinbefore described; C, is the recess for
receiving the rivets between the two parts D and D', of the spring jaw; the said parts
are jointed together at E; F, is the spring for automatically closing them when
released from the action of the punch b, of the press which punch is of a tapered form
as shewn; G, is a coiled helical spring on the pivot or hinge pin H, of the jaw A the
said spring bearing against the head of the pin H and the inner end of the jaw A,
whereby a small amount of downward play is allowed to the free end of the jaw A, as
shewn in dotted lines in figure 1 so that it shall by the descending action of the
punch b, adjust itself to the thickness of the material to which the rivets are to be
applied; I, is a set screw working in the part D, of the jaw and bearing against the
part D, by operating which screw in the right direction the recess C can be enlarged
if required to suit the size of rivets to be used; the dotted lines at c, figure 1 represent

page_text: a tubular rivet which has been applied to a piece of material d, by the use of my
swinging spring jaw A; e, in figure 1 is the usual die and f, the handle of the press.
By this arrangement the rivets can be applied in an expeditious and simple manner
the arrangement also allowing of the rivets being applied accurately in the places
required the following being the mode of operation.
The punch b, and handle f, of the press being raised as shewn in full lines in figure 1
and the swinging spring jaw A in the position shewn in dotted lines.in figure 2 in
order to apply an ordinary tubular rivet such as is shewn in figure 5, to a piece of
material it is only necessary to place the rivet with its head upwards in the recess C,
of the spring jaw A and then to swing the latter into position between the punch b, and
the die e, of the press a; the material d, to receive the rivet is then placed between
the under side of the jaw A and the die e; the handle, being now depressed as shewn
in dotted lines, figure 1, the punch 6, will be forced down and will first move the
outer end of the jaw A, down onto the material as indicated by the dotted lines in
figure 1, and will then force the rivet through the material d, (the parts of the spring
jaw A, opening as shewn in figure 3 to admit of the passage through them of the rivet
and punch) the lower end of the rivet being upset by the die e, (as shewn in the dotted
lines in figure 1) in the usual manner. The handle f, of the press a, being now
released the punch b, and jaw A, will rise into the position shewn in full lines in
figure 1 and the parts D and D', of the jaw A will be closed by the spring F as shewn
in figure 2; the material d, with the rivet e, applied can now be removed and the
spring jaw A, swung into the position shewn in dotted lines in figure 2 ready to receive
another rivet and so on.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed I declare that what I claim is :-
1. The combination with a machine or press for securing rivets, eyelets and the like
of a swinging or hinged spring jaw in the manner and for the purpose substantially
as hereinbefore described.
2. The swinging spring jaw substantially as set forth and illustrated in figure 4 of
the accompanying drawings.
3. The improved machine for securing tubular rivets, eyelets and the like hereinbefore
described and represented in figures 1, 2 and 3 of the accompanying drawings.
