PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Box Hooks, Snecks, or Clasps
for use with Moulding Boxes.
I, DAVID GILLIES, Junior, of Bonnybridge, Stirlingshire, Scotland, Engineer,
do hereby declare the nature of my said invention to be as follows :-
The object of my invention is to effect improvements in the manufacture of box
hooks, snecks or clasps, as used in iron foundries for moulders boxes.
In carrying out my invention I employ a forging hammer or stamp, fitted with
dies, so constructed that the necessary forms and operations of bending, flattening
and finally shaping, are imparted to the hook, sneck, or clasp, from the straight
iron bar. The hook is afterwards finished by being pressed through a steel plate
having the exact form of the finished hook formed therein, whereby any surplus of
metal or roughness round the edges and hole are removed.

COMPLETE SPECIFICATION.
Improvements in the Manufacture of Box Hooks, Snecks, or Clasps
for use with Moulding Boxes.
I, DAVID GILLIES, Junior, of Bonnybridge, Stirlingshire, Scotland, Engineer,
do hereby declare the nature of my said invention and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement :-
The object of my invention is to effect improvements in the manufacture of box
hooks, snecks, or clasps, as used in iron foundries for moulders' boxes.
In carrying out my invention, I employ a forging hammer or stamp, fitted with
dies, so constructed that the necessary forms and operations of bending, flattening,
and finally shaping, are imparted to the hook, sneck, or clasp, from the straight iron
bar. The hook is afterwards finished by being pressed through a steel plate having
the exact form of the finished hook formed therein, whereby any surplus of metal
or roughness round the edges and hole are removed.
And in order that my said invention may be particularly described and ascer-
tained, reference is hereby made to the accompanying drawings, in which similar
letters of reference indicate corresponding parts.
Fig. 1 illustrates the form of the hook at the first stage of the process, the
straight bar having been heated, the hook a partially formed, and the boss b pro-
vided for the formation of the eye.
Fig. 2 illustrates the next stage of the process, the hook a being further bent,
and the surplus finger or fin c being bent and prepared for removal.
Fig. 3 illustrates the perfected hook, which is effected by passing the same, while
still in a heated state, through a steel plate of the exact form required; the eye d
being punched at the same time. The sectional forms of the figures are shown
at e f and g.
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. In the manufacture of box hooks, snecks, or clasps, for use with moulding

page_text: boxes, the application and use of forging hammers or stamps fitted with dies,
whereby the necessary forms and operations of bending, flattening and shaping are
imparted to the same from the straight iron bar, substantially as herein before
described and illustrated by the drawings.
2. The improvements in the manufacture of box hooks, snecks, or clasps, for
use with moulding boxes, substantially as herein before described and illustrated
by the drawings.
