PROVISIONAL SPECIFICATION.
Improvements in and relating to Grinding Apparatus for Use in
Lathes.
I, ALBERT HARRY PARKER, Dental Mechanic, of Rozel House, Spilsby Road,
Boston, in the County of Lincoln, do hereby declare the nature of this invention
to be as follows:-
The machine is constructed to supply a grinding wheel or stone in a lathe,
with water, after the following manner:-
Firstly. A zine trough on which is situated a zinc cistern.
Secondly. A rod resting horizontally on the trough, beneath the cistern.
Thirdly. A small vice (to receive a brush,) which slides on the mentioned rod.
The vice is constructed on the rod, so as to enable the operator to adjust it to
receive water from a drop tap in the above mentioned cistern.
Fourthly. The brush, (which is circular) placed in the vice, acts as an inter-
mediate wheel between the cistern and the grinding wheel.
Fifthly. The brush is held in a fixed position by the vice;
The advantage of the circular brush is, that when the grinding wheel has
worn down the one part, it can be turned a little untill the whole brush is used.
Sixthly. The vice is so made that a circular sponge can take the place of the
brush, if required.
Also
Seventhly. Provision is made in the machine that the intermediate brush-
wheel may be adjusted in any way required to serve different sized wheels.
provision is made for the cistern to be adjusted to serve the intermediate brush-
wheel in whatever position it may be required.
Eighthly. A moveable hand-rest is situated on the front of the machine,
enabling the operator to steady his hands while at work on a grinding wheel.
Dated this Sixteenth day of September 1898.

Ìmprovements in and relating to Grinding Apparatus for Use in
Lathes.
ALBERT HARRY PARKER, Dental Mechanic, Rozel House, Spilsby Road, Boston,
Lincolnshire, 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:-
By reference to the accompanying drawing the nature of this invention may

page_text: be seen. The letters A, B, denote the base of a metal trough it can be made in
sizes to suit various kinds of lathes. The trough is required to support rod C, D,
cistern and hand-rest F. Also to receive the waste water from the above
mentioned cistern E.
The portion marked is a hand-rest which can be raised or lowered and fixed
in position by thumb-screws G and H.
The rod marked on the drawing C, D, is required to support the vice indicated
by letter K, and can be raised or lowered in the slots on either side of the trough
marked M and N respectively.
The rod is held in position by the thumb-screw Q.
The vice K receives a circular brush or sponge (which can be fixed in the
desired position by thumb-screw R).
The letter Q indicates a circular brush in position serving an emery wheel in
a lathe-head.
The vice K can be slipped horizontally along the rod C, D) or be moved
simultaneously with it in the slots M, N, in order to suit grinding-stones in what-
soever position they may be attached in a lathe.
The letter E indicates a metal cistern holding water-which flows through
the tap marked S. T marks a metal shelf on which the cistern E slides horizon-
tally between the sides of the metal trough marked A¹ B'.
The shelf T can be moved backward of foreward a similar movement being
applied to the cistern E combined with the shelf.
The movement of the cistern E and the shelf T are identical with the move-
ments of vice K and rod C, D.
(The slots M, N, sloping backwards with the sides of trough A B) enabling
the water from the tap S to flow on the circular brush or sponge indicated by
the letter Q whenever it is required to serve a grinding stone or the like in any
lathe.
The vice (K) the jaws of which are curved-thus allowing the brush held by
the same to lean to-wards the grinding stone it may be serving, or if reversed,
(the vice) on the rod (C, D) will leave a greater distance; thus allowing a
larger grinding stone to be used.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is―
1. The particular shaped trough here described.
2. The movable handrest.
3. The method of using the horizontal rod for suspending the novel vice-
in short all the movements that the rod and vice can be put through on the
novel trough.
4. Of utilizing a circular brush or sponge as an intermediate means for supply-
ing a grinding stone and the like in a lathe with water.
5. The particular shape of the vice, (K,).
6. The movements-described above-of the metal shelf T and cistern.
