Improvements in Means Employed when "Towing" or "Scouring”
Ceramic Productions in the Clay or Biscuit State of Manu-
facture.
I WILLIAM HALES TURNER of Chell Lodge Tunstall Earthenware Manufacturer
do hereby declare the nature of this invention to be as follows:-
A box made to fit the "whirler" or lathe "head" in the most convenient form for
the workman: one or more sides of this box made of glass: so that the workman
can see whilst he is "scouring" or "towing" the article in the enclosed box-into
this box I introduce a powerful current of exhaust air also a powerful current of air
pressure to lift, force, & drive all dust as soon as it is made by the workman these
currents of exhaust & pressure air are fixed in the most convenient form for the
article that is being "scoured
29 " towed
so that the " Scourer or "tower" cannot
possibly inhale any dust or the dust cannot possibly get into the workshops as it is of
a very deteriorating nature to health. The air pressure also expedites the work of
towing" & "scouring' & makes a better finish to the article "scoured "
"towed.'

page_text: in all the figures, like parts are indicated by similar letters of reference.
I will first describe my invention as applied to the towing" bench. a represents
the bench or table, and the whirler, which is mounted at the upper end of a
shaft or spindle 61, to which rotary motion is given, as is well understood.
11
The whirler b receives the article to be "towed," when the latter is of a circular
form, and communicates rotary motion thereto, whilst the " "
work thereon. The bench or table a has fixed thereon a box c, which encloses the
tower is performing his
whirler and the article to be "towed," except that a space or opening c is made in
the front thereof, to enable the workman to introduce and remove the article to be
towed," and to enable his hands to perform the work thereon. This box c has its
back and upper part of the front made of glass, whilst the lower part c¹ of the
front, which is open at its top, and the top c are made of either wood or metal; if
desired however, the box e may be made entirely of glass, so as to admit as much light
as possible to the interior thereof. The interior of the box has fixed therein a
perforated or wire work screen c, and the space enclosed by such screen c° com-
municates, by perforations a¹ in the table or bench, with the enclosed space d
underneath, from which latter the air is exhausted by a suitable fan or other apparatus.
There are other perforations a³ in the table or bench a, which communicate with a
dust box e, the back of which, by perforations e³, communicates with exhaust space d.
fis a nozzle connected to a pipe f; which supplies a powerful current of air, which
is directed by the nozzle in the most desirable position on to the work, so as to
lift or blow the dust from the work and force and drive it away from the workınan
towards the back of the interior of the box c, where, aided by the exhaut in the
chamber d, it is caused to pass partly through the screen c and perforations a
into the space d, and partly through the perforations a² into the dust box e,
the finer particles passing from such box e, through the perforations e¹, into the
space d.
The dust collected in the box e, and in the exhaust space d, is removed from time to
time and re-used or otherwise disposed of.
"
"
The apparatus represented at figures 5 to 9 is applicable for use in "scouring"
articles which are of irregular shape, but, by adding a whirler or lathe head & or
rotary brush or "scourer" thereto, it may be used for either "towing
circular articles. In this case the nozzle f¹ for the forced air current is placed
or "scouring"
within the box c and is formed with a narrow elongated orifice, so as to deliver a
broad thin blast of air on to the work being "towed'
the perforations a¹, a³, and the screen and dust box e described with respect to
ог scoured within the box c;
igures 1 to 4, are in this arrangement dispensed with, and in lieu thereof the box c
as an opening e' in the back thereof, which, by conduits c, communicates with the
xhaust chamber d; the pipe or conduit for the forced blast of air is connected to
he exit orifice of a fan g, the inlet orifice of which is connected, by conduit h, with
he exhaust chamber d. By these means the same fan is caused to supply both blast
nd exhaust currents and, if desired, two or more benches may have the blast and
xhaust conduits connected to the same fan.
"
The spindle represented at figure 10, and which is fitted with a whirler, brush or
Scourer of any suitable form, is made with a bore 62 at its upper part, and is
rovided with cross holes 6 communicating therewith, whilst the bearing i is formed
ith an annular channel or groove i¹ communicating with such holes 63 and connected
opening with a suitable pipe conveying a blast of air thereto, or if desired such
pening may be connected with a suitable exhaust, so as to draw the dust away
rough the hollow spindle b.
دو
By the means herein described, the dust, as it is produced in the processes of
towing" or "
scouring ceramic productions, is blown off the work away from
e operative, and an exhaust draws such dust away into suitable enclosures,
ereby rendering the workshop free from dust and therefore healthier than
retofore.
It is evident that the construction and arrangement of the parts may be varied
hont departing from the peculiar character of my invention.

Having now particularly described and ascertained the nature of my said
tion, and in what manner the same is to be performed I declare that what I
claim is :-

in such processes is carried away from the operative, substantially as herein shown
and described.
