Improvements in Processes and Apparatus for Polishing Hackle and
other Pins and other Small Metal Articles.
We, FRANCIS HALLEY and DAVID HALLEY of South Ward Road, Dundee, in the
County of Forfar, North Britain, Hackle Makers, do hereby declare the nature of this
Invention to be as follows, that is to say:
Our said Invention has for its object, to improve, simplify, and render more expe-
ditious the operations employed in polishing various small metal articles and is
advantageously applicable for treating steel pins for hackles, cards or gills.
In carrying out our Invention in the case of steel pins we take the pins after having
been subjected to suitable grinding machinery, and instead of subjecting them
to a mangling process as is ordinarily done, we place them loosely in a rotating
barrel or cylinder along with sand and water. The barrel is on an inclined shaft with
which it is concentric and its upper end is open whilst its lower end is made with
rounded corners. A large part of the barrel is by preference made of iron and its
inner surface is provided with a number of pins projecting inwards.
At the second stage the sand is separated by placing the pins with the sand and
with water inside of a sieve or riddle placed concentrically in the same or a similar
rotating barrel. This sieve or riddle consists of a cylindrical metal shell with a flat
permeable bottom; and when in use it is fixed on the end of a spindle projecting from
the centre of the bottom of the barrel. The construction of the sieve or riddle may,
however, be modified.
The pins may next be subjected in the same or a similar rotating barrel to the
action of oil and soot or other polishing material; this process is not however required
in all applications of the Invention.
After being washed and cleaned from the oil, if necessary, the pins are subjected in
the same or a similar rotating barrel to the action of sawdust and water; and they are
finally dried by subjecting them to dry sawdust in the same or a similar rotating
barrel.

page_text: Improvements in Processes and Apparatus for Polishing Hackle and
other Pins and other Small Metal Articles.
We, FRANCIS HALLEY, and DAVID HALLEY, of South Ward Road, Dundee, in the
County of Forfar, North Britain, Hackle Makers, 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, that is to
say:
Our said Invention has for its object to improve, simplify, and render more expe-
ditious the operations employed in polishing various small metal articles, and is
advantageously applicable for treating steel pins for hackles, cards, or gills.
In carrying out our Invention in the case of steel pins, we take the pins after having
been subjected to suitable grinding machinery, and instead of subjecting them to a
mangling process as is ordinarily done we place them loosely in a rotating barrel or
cylinder along with sand and water. The barrel is on an inclined shaft with which it
is concentric, and its upper end is open, whilst its lower end is made with rounded
corners. A large part of the barrel is by preference made of or lined with iron, and
its inner surface is provided with a number of pins projecting inwards.
At the second stage the sand is separated by placing the pins with the sand and with
water inside of a sieve or riddle placed concentrically in the same or a similar rotating
barrel.
The pins may next be subjected in the same or a similar rotating barrel to the
action of oil and soot or other polishing material; this process is not however required
in all applications of the Invention.
After being washed and cleaned from the oil, if necessary, the pins are subjected in
the same or a similar rotating barrel to the action of saw dust and water; and they are
finally dried by subjecting them to dry sawdust in the same or a similar rotating
.barrel.
And in order that our said Invention and the manner of performing the same may
be properly understood we hereunto append a sheet of explanatory drawings to be
hereinafter referred to and representing apparatus which we employ in' carrrying out
our Invention.
Figure, 1. of the drawings is a sectional elevation of the apparatus as used for the first
stage of our improved process; and figures, 2, and 3, show the apparatus as used for
the second stage, these figures being a plan and section of the apparatus as placed
vertically, it being however used in an inclined position. In these figures the same
reference numerals are used to mark the same or like parts wherever they are
repeated.
The apparatus shown in figure, 1, is carried on a base plate, 4, having on it
bearings, 5, on a horizontal shaft, 6, which has fast on it a pulley, 7, for a driving
belt, and a bevil pinion, S. On the shaft, 6, there is centered a frame, 9, made with

page_text: bearings, 10, for a shaft, 11, which is driven from the shaft, 6, by means of a bevil
wheel, 12, gearing with the bevil pinion, 8. The frame, 9, with its shaft, 11, can be
placed in a more or less inclined position with the bevil wheel, 12, always in gear with
the bevil pinion, S, the desired inclination being given to the frame, 9, by means of a
cam, 13, arranged to bear it up. This cam, 13, is fixed on a shaft, 14, carried in
bearings, 15, upon the base plate, 4; the shaft, 14, having fixed on it a worm wheel, 16,
with which there gears a worm, 17, fast on a vertical shaft, 18, held in a brackot, 19,
fixed to the base plate, 4. On turning the vertical shaft, 18, by means of a lever or
handle the cam, 13, can be moved so as to raise or lower the frame, 9. The outer end
of the shaft, 11, carried by the movable frame, 9, is flanged and has bolted to it a
plate, 20, to which is hinged the bottom, 21, of a barrel, 22, which when secured to
the plate, 20, is concentric with the shaft, 11. The hinged connection is provided to
facilitate the emptying of the barrel. The barrel, 22, consists of a cylindrical part of
wood with an inner shell, 23, of iron which latter joins the iron bottom, 21, with
rounded corners. The inner cylindrical shell, 23, has fixed in it a number of pins
projecting inwards.
The barrel, 22, shown in figures, 2, and 3, as fitted with a sieve, 24, for the second
stage of the operations is the same as that shown in figure, 1, and hereinbefore
described; but there is fixed at the centre of the bottom, 21, a spindle, 25, on which
the sieve, 24, is keyed. This sieve consists of a cylindrical sheet iron shell, 24, fixed
on a wheel-like frame, 26, made with an elongated boss, 27, which is keyed on the
spindle, 25. A bottom, 28, of perforated sheet iron is fixed on the inside of the
frame, 26, and the sand passes through it when the pins and sand are placed in
the sieve and the barrel is made to rotate.
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 combination of processes for polishing pins and other small metal
articles, and comprising first treating them with sand and water in an inclined rotating
barrel, secondly treating them in an inclined rotating sieve to separate the sand, thirdly
treating them in an inclined rotating barrel with sawdust and water and finally drying
them in an inclined rotating barrel with dry sawdust, all substantially as hereinbefore
described.
2-The improved combination of processes referred to in the first claim with the
addition of a treatment with oil and soot or other polishing material substantially as
hereinbefore described.
3 The combination of parts substantially as shown, in figure, 1, of the accom-
panying drawings and hereinbefore described.
4 The combination of sieve and barrel substantially as shown in figures, 2, and 3,
of the accompanying drawings and hereinbefore described.
Dated this Twentieth day of August 1888.
