I, HENRY STUTTLE, of Kingsland, Shrewsbury, in the County of Salop,
Iron and Brass Founder, do bereby declare the nature of the said Invention
for "IMPROVEMENTS IN THE CONSTRUCTION OF HYDRAULIC PRESSES POR THE MANU-
FACTURE OF SHEET LEAD, PIPES, BARS, AND WINDOW LEAD," to be as follows:-
This Invention relates to certain improvements in the construction of
hydraulic presses whereby the manufacture of sheet lead, pipes, bars, and
window lead is greatly facilitated and economised. A disadvantage which
frequently results from the mode in which presses employed for such purposes
are usually constructed is that the head of the water cylinder is liable to be
forced off with the pressure or burst at the top. This evil is prevented by
connecting the bed plate of the machine with the head of the water cylinder
by means of stay pins or bars of suitable strength, the lower and upper ends
of such stay pins or bars being respectively provided with snugs which are
inserted into corresponding recesses in the bed plate and the upper part of the
water cylinder, thereby holding the latter firmly in its place.
The ram
employed for the purpose of supporting the die in the interior of the lead
container is hollow and is furnished with internal brackets to support and
give additional strength to the dio through which the lead is forced for the
manufacture of the articles. For the manufacture of sheet
constructed with a convoluted slot therein, such slot being
and the die is
of any desired

page_text: width according to the thickness which it is intended the sheet lead to be
manufactured shall possess. If pipes, bars, or window lead are or is to be
made, then dies constructed with any desired number of apertures of the
requisite figure are used, the die being in each case supported in all those
portions thereof which are not occupied by slots or apertures by brackets in
the interior of the hollow ram as before mentioned. It is unnecessary further
to describe this portion of the machine, inasmuch as the details of manu-
facture are well known, the novelty of this Invention consisting in the
manufacture of two or more pipes, bars, and lengths of window lead by one
operation, and also of sheet lead of any desired width and thickness without
the necessity of subsequent rolling. In the case of sheet lead the convoluted
sheet as it issues from the die is opened and flattened by any suitable means.
The lead container is connected with the ram of the water cylinder by means
of pins secured to a flange attached to the ram, such pins working in snugs or
projections formed on the exterior of the lead container. The flange is pro-
vided with a stud in the centre thereof for covering the metal in the lead
container when the ram carrying the flange is forced towards the die. The
effect of this arrangement is that when the ram has forced the metal through
the die and is again raised the lead container is also raised with it, the space
between the flange and the top of the lead container being regulated by the
length of the before-mentioned pins. The lead container having been thus
raised is ready to receive a fresh charge of lead in the ordinary manner, the
space between the lead container and the flange being sufficient to allow for
feeding and skimming off dross.
