Improved Apparatus applicable for Use as a Spice Grinder, Nail
Puller, and Gas Wrench, and for other Domestic Purposes.
We, FREDRICK SARTIN MCKITTRICK, of Johannesburg, South African
Republic, Blacksmith, and WILLIAM WILKSON, of Johannesburg, South African
Republic, Mine Manager, do hereby declare that 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, and by the accompanying
drawings: :-
Our invention consists of a tool or implement for domestic use, wherewith spices
such as nutmegs, ginger, cloves and the like may be readily ground to a fine
powder in such quantity as the user may desire; and by detaching the grinding
apparatus, the tool may be used for pulling small nails, as a gas fittings wrench
and for sundry other domestic purposes.
A, A, are a pair of grips or jaws passing through two rectilinear slots in the
cover of the cylinder C and connected at their lower ends to a circular disc or
piston B by two pins a, a. The disc or piston is allowed to work freely in the
cylinder or shell C, and is connected to the wooden handle D, by means of the
shank E, which passes through the helical spring F, and the handle D, and is
fixed by the milled nut b, which also serves to adjust the pressure of the spring F.
The jaws are made to open by pushing up the handle D, the pressure of the
spring F, causing them to effect a firm grip upon anything that may be placed
between them immediately after the pressure on the handle is removed.
G, is a small steel disc with saw teeth grooves cut in the face of it. H, is a
small handle connected with the disc by the spindle 1, which works in a bush in
the top of the slide bar J, which is attached to the cylinder C, by means of the
two brackets K, K', screwed, or otherwise fixed to the side. L, is a small helical
spring which serves to maintain the pressure of the grinder, or cutter G, up
against the material in the jaws which is being operated upon.
The whole of the tool, with exception of the cutter, may be made of malleable
cast iron, brass or other suitable material; and the disc may be made in other
suitable form than the one above described, it may be made of case-hardened cast
iron, steel, or it may be made of a suitable thin metal with holes punched in, the
under rough surface caused by the punctures serving to grind the spice.
It must however be understood that we do not confine ourselves to the use of any
of the metals named herein for the construction of the body of the tool or of its
working parts, nor do we confine ourselves to any particular form of cutter, but
may use any that will serve the particular purpose herein 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 use of a pair of metal jaws, working in a cylinder and acted upon by a
spring and handle for the purpose of holding spices and the like while they are
being ground to a fine powder, and for other purposes; substantially as described
in the foregoing Specification and by the accompanying drawings.
2. The use of a detachable cutter or grinder to act upon the material held in
the jaws; substantially' as described in the foregoing Specification and by the
accompanying drawings.

page_text: 3. The general arrangement of the parts of the tool or implement substantially
as described in the foregoing Specification and by the accompanying drawings.
