COMPLETE SPECIFICATION.
Improved Machine for Making Rivets and Bolts.
JEREMIAH SMART and WALTER SMART, Machinist, 44 High Street Blackheath
near Dudley Staffs 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 :-
Consists in a machine for making rivets & bolts constructed in the following
manner as shown by drawings left with Provisional Specification.
The shaft marked A has attached to it two cams B. C. upon revolving round the
cam B moves slides D with the projecting side attached which also moves slides E
which cuts off pin & carries with it slide F into position for snapping.
The cam C. works slide G & snaps rivet or bolt. Then cam B relieves slide D
& E which are drawn into position by springs No. 1 & 2.
The spring No. 3 attached at the back of slide F propells it into position for
cutting.
The screw pin running into spring 3 holds slide F. in the required position during
the snapping of rivet.
The feed pipe W attached to cutting off block X guides the iron into centre
of dies.
Letter H represents gauge for regulating length in head of rivet or bolt.
In making square neck bolts it is necessary for the machine to make two
movements similar to the above for making rivets.
This necessitates the addition of two extra cams & also two heading tools in

page_text: slide G. No. 1. acting as the bunting & No. 2. as the heading tool as shewn on
drawing accompanying the Complete Specification.
Working in the following manner the shaft marked A. upon revolving round
moves by cam B slides D & E which cuts pin off & carries slide F into position
for No. 1. bunting tool. Then cam C. works slide G. & bunts pin.
Then cam L. attached at the back of cam B. carries pin after bunting into
position of heading tool No. 2. which is headed by cam M. working slide G. a
second time.
Having now particularly described & ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is―
The method in which our machine makes rivets & bolts as shown by
Specification.
