Improvements in the Method of Manufacturing or Constructing
Cased (and Half-cased) Hames.
We, PARKES AND GNOSILL, LIMITED, of 26 Regent Street, Walsall in the
County of Stafford, Hame Manufacturers, and JOHN PARKES, also of the above
address, Works Manager and Director of the said Company, do hereby declare the
nature of this invention and in what manner the same is to be performed, to be
particularly described nd ascertained in and by the following statement:-
In the manufacture or construction of cased (and half-cased) hames it has
hitherto been usual to weld into the bottom of the case a short plug of plain round
iron and afterwards to work such iron, with the portion of the case welded around
it, into the required shape and punch a hole through the portion of the case welded
around the plug and through the plug itself for the throat tackle. This involves
the use of iron or of a low grade steel for the case, as high qualities of steel will
not weld; and in consequence the metal of the case is liable to split open under
the process of punching through it to form the hole for the throat tackle.
Moreover, apart from the question of punching, the case must either be made of a
greater thickness than would suffice if a high class steel could be and were
employed, or is much weaker than if made of such steel.
Now, the object of this invention is to make such alterations in the manufacture
or construction of the hames as will permit of a high class or weldless steel being
used for the cases.
As
According to this invention, the portion of the plug through which the hole is
formed for the throat tackle projects, preferably, beyond the end of the hame case
which is consequently somewhat shorter than usual to admit thereof. The plug is
first formed to its finished forged (or cast) shape, including the hole therethrough
for the throat tackle, and is then brazed into the lower end of the hame case.
no welding is thus required a high class steel may be used for the case (and for the
plug also if desired) whereby greater strength and elasticity is ensured. High
class steel also has the advantage of taking a better polish than iron or low class
steel, and of resisting more effectually the corroding action of the weather.
The invention hardly requires illustration, but in order to ensure that the means
of carrying it out shall be perfectly clear we have appended hereto a sheet of
drawings, in which Figure 1 shews, in longitudinal section, the lower end of a hame
case A previously to the insertion of the plug therein; and Figures 2 and 3 shew
elevations, taken at right angles to one another, of the plug B ready for insertion
into the end of the case. Figure 4 is a corresponding view to Figure 1, but shews
the plug B, in sectional view, in position within the end of the case A. The plug
is formed with a portion a to fit within the case and with a portion to project
therefrom. A hole c is formed through the part 6 to receive the throat tackle.
The base of the part b is, preferably, of the outside diameter of the end of the case
so as to avoid the appearance of a shoulder around the plug when placed in position,
and a shoulder is thus formed between the parts a and b of the plug, which is
however hidden when the plug is in place. The plug is simply brazed within the
case to fix it permanently therein. The portion of the case within which the plug
is inserted is, preferably, formed parallel, as shewn, for convenience in inserting
the plug.
While it is much preferred that the portion of the plug which receives the throat
tackle shall project from the end of the case, the whole plug may of course be
inserted within the end of the case and brazed therein, holes for the throat tackle
being first cut through the thickness of the case,

page_text: Having now particularly described and 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:-
1. In the manufacture or construction of cased (and half-cased) hames, forming
plugs for the throat tackle to their finished forged (or cast) shape and brazing
them into the hame cases, substantially as described and shewn, for the purpose
set forth.
2. In the manufacture or construction of cased (and half-cased) hames, forming
plugs for the throat tackle to their finished forged (or cast) shape and each with a
portion to enter within the end of a case and with a portion to project therefrom
and receive the throat tackle, and then brazing them into the cases, substantially
as described and shewn, for the purpose set forth.
3. In the manufacture or construction of cased (and half-cased) hames, forming
plugs for the throat tackle to their finished forged (or cast) shape and each with a
portion to enter the case shouldered down from a portion formed to project there-
from and receive the throat tackle, and then brazing them into the cases,
substantially as described and shewn, for the purpose set forth.
