COMPLETE SPECIFICATION.
Improvements in the Manufacture of Hammers for Engineers
and Fitters.
We, GEORGE RADFORD MATHER, and CHARLES JOIN MATHER, both of
Albion Foundry, Wellingborough, in the County of Northampton, Engineers, do
hereby declare the nature of our 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 our invention is to manufacture improved hammers for use in
fitting and adjusting cotters, keys, pins, wedges, and other parts of machinery,
and analogous operations.
The hammer head consists of a metallic shell or tube, of suitable sectional form,
and a smaller, transverse tube, formed in one therewith; the larger tube being
adapted to receive a filling of lead, tin, or other suitable metal, and the smaller
tube being adapted to receive the head of the handle.
And in order that our 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 is a side view, Fig 2 an end view, and Fig. 3 a longitudinal section, on
the line 1-2.
a is the outer tube, and 6 the inner tube, both cast in one or otherwise united
together.
Previously to fitting the handle, the shell is placed in a suitable mould, and a
quantity of molten lead, tin, or other suitable fusible metal, is poured into the outer

ends of the larger tube, as required, to suit the necessary weight of head.
soft metal is securely held in position in the outer tube a by means of the tube
round which the metal is poured. The handle is fitted to the tube b, as indicated
by dotted lines at c, the hammer being then ready for use.
When the striking ends of the hammer head (shown at d d by dotted lines) have
become worn by use, the metal may be removed by heat, and a new casting made,
as before described.
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. The improved construction of hammers for engineers and fitters, consisting
of two transverse tubes cast in one or otherwise united together, for the purpose
of receiving a filling of lead or other suitable metal in one tube, and the head of.
the handle in the other tube, substantially as herein before described and illustrated
by the drawings.
2. The improvements in the manufacture of hammers for engineers and fitters,
substantially as herein before described and illustrated by the drawings.
Dated 12th September 1892.
