PROVISIONAL SPECIFICATION.
Improvement in Manufacturing Axle Pulleys and the like.
JAMES COLLINS, 26 Cumberland Street Birmingham Brassfounder and
ANDREW BARTON MILNE 26 Cumberland Street Birmingham, Brassfounder's
Clerk do hereby declare the nature of this invention to be as follows:-
:-
In the usual manner the side pieces or cheeks of axle pulleys are attached to the
rame by rivets passing through the former and through studs or pillars on the
frame or front plate. We insert or cast into the studs strips of iron or steel of.
convenient shape and form on the edge of the cheeks corresponding notches, then
when the several parts are assembled the ends of the strips are bent over into the
notches securing the cheeks to the frame.

COMPLETE SPECIFICATION.
Improvement in Manufacturing Axle Pulleys and the like.
JAMES COLLINS, 26 Cumberland Street, Birmingham, Brassfounder and
ANDREW BARTON MILNE, 26 Cumberland Street Birmingham, Brassfounder's
Clerk, 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 :-
In the ordinary method of manufacturing axle pulleys, and other articles
consisting of several parts, the several parts have holes drilled or otherwise made
in them and are then fastened together by pins or rivets passing through the holes
& connecting the parts one to the other.
In our improved method, we cast pieces of iron, steel or other metal, having
ends projecting beyond the surfaces, into the main portions of the articles &
form corresponding notches, slots, recesses or holes in the other parts so arranged
that when the several parts are assembled together, the projecting ends of the
pieces can be inserted, bent, folded, doubled or rivetted into the notches, slots,
recesses, or holes and thus connect them together.
Fig. I shows side elevation of an axle pulley put together by our improved
method.
Fig. II shows an end view of the same.

Fig. IV shows one of the pieces "A" used.
(The same letters designate the same parts in all the drawings.)
In carrying out our invention we form slots, "C," Figs. I. II. III in the
casting patterns where we desire to fix the pieces "A" in the finished work ;-
then having placed them loosely in position, sand is rammed round the patterns
in the usual way, but when the pattern is withdrawn, the piece "A is held
by the surrounding sand; when the metal is poured in, the piece
"will be
found securely fastened in.

page_text: In the side plates, corresponding notches "B," Fig. I, are cast so that when the
parts are placed together, the ends of "A" can be bent, folded or doubled over,
into the notches "B," & hold all securely together.
We do not limit the application of our invention to the particular article or
shape shown, as the same may be modified to suit other requirements.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is :-
The employment of pieces of metal cast into one part of an article and fastened
into notches in another part, to avoid the necessity of drilling. Substantially as
above described & shown.
