receiving its motion by means of an eccentric, cam, crank, or other equivalent
device. Underneath the reciprocating plate and on the stationary, bed there may
be placed a piece of emery, leather, or other substance, for polishing the wire.

COMPLETE SPECIFICATION.
Improvements in, the, Method of and Apparatus for Polishing Wire.
I, EDWIN JOHN LISTER, of Roe Head" Mill,Mirfield;in-the County of York,
Card Maker 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 :-
+
This invention consists in a new means or method of polishing heat hardened
and tempered steel wire employed for card making purposes.
In carrying out this invention, the wire to be polished is, unwound from one
reel or block onto another reel or block, and at some convenient place between the
two reels, I cause the wire, whilst travelling, to be rolled over backward and
forward between one or more reciprocatory surfaces thus presenting the whole of
the surface of the wire to the action of the emery or other polishing substance,
whereby the polishing of the wire is effected. The apparatus employ for rolling
over the wire backwards and forwards consists of a plate bearing on the travelling
wire on a stationary bed, the reciprocating plate receiving its motion by means of
an eccentric, can, crank, or other equivalent device. Underneath the reciprocating
plate, and on the stationary bed, there may be placed a piece of emery, leather, or
other substance for polishing the wire.
In combination with the above named apparatus I employ mechanism for cleaning
the said wires preparatory to its being polished, all of which is more particularly
hereinafter described and shewn in the accompanying drawings, wherein
Fig. 1 is a plan-of-my improved mechanism for polishing wire.
Fig: 2 is section of same through the line a-b.
A represents a table of any suitable construction, and B a reel or block from
which the wire is unwound, and C is another reel or block onto which the wire is
wound. Between the two reels is a table or bed plate upon which are attached

page_text: :―
one or more sheets of emery E, over which the wire G is made to travel, being
kept in contact with the emery by weights Hand I. Between these two weights H
and I the wire is caused to be rolled over backwards and forwards in the following
manner Upon the bed D is. another piece of, emery J, upon which the wire
travels, and bearing upon the wire is a reciprocatory.plate L attached to rod N, in
connection with the eccentric O, caused to rotate by strap or other motive power;
therefore as the eccentric revolves, the plate 1 is made to reciprocate backwards
and forwards upon the travelling wire, which it rolls over as shewn in enlarged
detail Fig. 3, where the wire is indicated in black line, and its changing position
. shewn by dotted circles.
Instead of the wire travelling over a stationary bed and underneath a reciprocating
plate as already described, the said wire may travel between two reciprocating
surfaces for the purpose of rolling over the wire whilst it is travelling, as indicated
in section Fig. 4, where in this case there are two eccentrics O and O', and two
rods N and N1, which work backwards and forwards for the purpose of turning the
wire over between their rubbing surfaces L and L.
In combination with the above apparatus for rolling over the wire for the
purpose of polishing it, I employ automatic means for cleaning the wire preparatory
to its being polished, and this is illustrated in Fig. 5, which is a plan view of the
combined parts, and Fig. 6 an end view of the wire cleaning apparatus.
In this.
case the wire is unwound from a reel or block such as B already referred to, and
on its way to the rolling over surface Lit passes against a vertical plate P having
on its face sheets of emery E, and the said wire is alternately pressed against, the
emery whilst travelling in the following manner:-A grooved pulley Q is caused
to revolve, and on the axle of the said grooved pulley are two cam-like projections c
and d, and in contact with these cam-like projections are two bent lever arms R,
their upper ends being provided with little blocks S, which are alternately pressed
against the travelling wire by the revolving cams e and d, springs T being used for
forcing the levers R in the opposite direction. After the wire has been cleaned in
the manner described, it passes under weighted blocks H and 1 and thence to the
rolling over surface. L, under one or more weights and emery sheets, and is finally
wound onto the winding-on roller or "windsel C.
By the employment of the mechanism herein shewn and described,, the wire is
cleaned and polished by self acting mechanism.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare, that what I
claim is :-
Firstly. For polishing wire, the use of a reciprocating plate for rolling over the
wire, in a backward and forward direction, on a stationary surface as described, and
shewn in Fig. 1.
Secondly. For polishing wire, the use of two reciprocating plates for rolling
over the travelling wire in a backward and forward direction as described, and
shewn in Fig. 4.
Thirdly. For polishing and cleaning wire, the use of one or more reciprocating
plates for rolling over wire, in combination with means such as shewn in Figs. 5
and 6, for cleaning the said wire, all' as described and shewn.
