Year: 1876

page_text: LETTERS PATENT to William Edward Toale, of Worsley, in the County of
Lancaster, Lamp Manufacturer, for the Invention of "CERTAIN IMPROVE-
MENTS IN MACHINERY AND BRUSHES FOR CLEANING WIRE GAUZES AND OTHER
METAL SURFACES.”
Sealed the 1st December 1876, and dated the 5th June 1876.
PROVISIONAL SPECIFICATION left by the said William Edward Teale at the
Office of the Commissioners of Patents on the 5th June 1876.
WILLIAM EDWARD TEALE, of Worsley, in the County of Lancaster, Lamp
Manufacturer. " CERTAIN IMPROVEMENTS IN MACHINERY AND BRUSHES
CLEANING WIRE GAUZES AND OTHER METAL SURFACES."
FOR
The object of my Invention is the more effectual and speedy cleaning of wire
gauze covering of mining plants, lamps, or other metal surfaces, and consists in the
application and use of two or more rotatory mandril shafts (hereinafter called man-
Around one end of the
drils) placed parellell to each other in suitable framework.
said mandril I fix a number of brushes. On each of the said mandrils I also securo
a grooved driving pulley.
In order to give motion to the said mandrils I arrange in suitable framework an
ordinary driving wheel, having on its periphery two or more grooves to receive
driving bands, the said driving bands I place around the grooved pulleys on the
mandrils and the driving wheel. Motion is given to the driving wheel by an
ordinary treadle; motion being given to the driving wheel the mandrils (on which
the brushes are fixed) may be driven at a high rate of speed.
In order to clean the wire gauze of mining lamps I set the brushes in motion,
and push the said gauze over one of the brushes, when all particles of soot or dirt
are driven from the inside to the outside of the wire gauze, and is rapidly removed
thence by the brushes operating on the outside of the said gauze.
Instead of putting the wire gauze over the brushes by hand I may fix the said
wire gauze in a suitable block, and give lateral motion to the mandrils by means of
a lever, which shall pass the brushes the requisite distance inside and outside the
wire gauze, so as to effect a proper cleaning of the same.
Any kind of metal or glass tube may be cleaned and polished by the action of
the revolving brushes, as above described.

Figure 1 shews a front elevation, and Figure 2 an end view of the mechanical
arrangements for carrying out my Invention.
A, A, A, is a strong framework carrying at about its centre a cranked shaft B,
upon which is secured a grooved driving wheel C; D is a treadle fastened on the
shaft F, which works freely on suitable bearings F¹. The treadle D carries an
antifriction bowl C¹, over which a chain E works freely operated by the crank
shaft B1; G, G, are driving bands; H, H, are mandrils, on each of which is fixed a
grooved pulley. The said mandrils work in suitable bearings H, H¹. On the
ends of the mandrils I fix (by means of screws) circular brushes marked I and J
respectively.
In order now to carry my Invention into practical effect I give notion to the
treadle, and thereby cause the brushes I and J to revolve rapidly; I then take the
wire gauze covering of a mining lamp, and pass it over the brushes I, when all par-
ticles of soot or dirt are driven through the said gauze, and are instantly removed
thence by the brushes J, the gauze being turned round in the hand every part
thereof will come in contact with the brushes J, when the operation of cleaning will
bo completed.
Having now described the nature and particulars of my Invention, I would have
it understood that I do not claim any of the parts separately marked by the letters
A, B, C, D, E, F, G; but what I do claim as new and of my Invention as secured
to me by the herein-before in part recited Letters Patent is, the combination and
nrrangement of mandril shafts working parallel to each other, and carrying brushes,
in the manner and for the purpose herein described and illustrated.
In witness whereof, 1, the said William Edward Teale, have to this my Speci-
fication set my hand and seal, this Twenty-ninth day of November, One
thousand eight hundred and seventy-six.
WILLIAM EDWARD TEALE. (L.S.)
