COMPLETE SPECIFICATION.
Improved Combined Burner and Scraper for Removing Paint
and Varnish.
I, PERCY RICHARD JULIUS WILLIS, of Fairfield, Kingston-on-Thames, in the
County of Surrey, Consulting Engineer, (a communication to me from abroad
by Benjamin Franklin Aiken, of Freetown, Mass., U.S.A., Machinist,), 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 relates to paint removing devices of that class which com-
bines a burner, a tank for supplying the burner with fuel, and adapted to serve
as a handle, and a scraper whereby an implement or tool may be provided,
capable of being operated by one hand, if necessary, and of softening or
loosening the paint or varnish and of removing the loosened material.
The object of the invention is to provide a device of the kind which will not
only be of cheap construction, but which will be more durable, less likely to
get out of order, and more convenient to use than like devices at present
employed.
The invention consists in the novel construction and combination of the
several parts, as will be hereinafter fully set forth, and pointed out in the claims.
Reference is to be had to the accompanying drawings forming a part of this
specification, in which similar characters of reference indicate corresponding
parts in both figures.
Figure 1 is a central vertical section through the improved device, and Fig. 2
is a side elevation of the same.
A cylinder A is provided as the handle of the device. This cylinder is
adapted to contain the naptha or other liquid to be supplied to the burner B,
to be hereinafter described. A packing of cotton is placed at one end of the
cylinder, preferably at the lower end; the upper surface of the packing being
designated by the dotted lines a, although the packing may be used in greater
or lesser amount than indicated in the drawings. The lower end of the cylinder
is practically closed, being provided however, with an outlet opening 10, sur-
rounded by a threaded collar 11, and from the front surface of the cylinder
at its bottom an arm 12 is horizontally or outwardly projected, and to said arm
a scraper 13 is secured by means of a screw or its equivalent. The scraper
employed may be a knife of any desired shape for removing the loosened paint
or varnish from a surface.
:
A tube 22 is screwed into the collar 11 at the bottom of the cylinder or
handle A. This tube forms a portion of the burner B, being in communica-
tion with a chamber 23, made adjacent to one side of the burner and extending
along the head, as shewn in Fig. 1. The ends of the chamber 23 are closed
by removable plugs 24.
The upper portion of the chamber 23, or that portion which extends trans-
versely of the burner, is provided with a tapering opening 25, which receives
one end of a needle valve 26, screwed into the head portion of the burner;

page_text: the valve terminating at its other end in a disc 27 or its equivalent, so that
it may be readily manipulated. A gland 28, in the form of a cup, is provided
for said valve, and is secured upon the head portion of the burner, in which
naptha may be burned to start the device by heating the burner. The burner
is provided with the usual combustion chamber 29, and at the outlet of this com-
bustion chamber a hood 30 is formed to prevent the flame being affected by
currents of air.
A plug 14 is screwed into the opposite end of the cylinder, and is provided
with a shoulder 15, between which and the edge of the cylinder, a packing
ring 16 is interposed. The plug is grooved to contain a packing ring 17 which
makes an air and liquid tight joint between the plug and a sleeve 18 slidably
mounted over the cylinder and prevented from removal by the lugs 19, slidable
in grooves 20 and secured to the plug 14 by screws 21. A passage 31 extends
through the plug 14, and is normally closed on its under side by a spring-
pressed valve 32. A spring 33 is arranged between the plug 14 and a cap 34,
screwed over the sleeve 18, and having an aperture 35.
In operation, the plug 14 is removed and naptha is inserted into the cylinder A
and the plug replaced. The cap 34 is then depressed with the thumb or finger
or palm of the hand resting over the aperture 35. The air in the interior of
the sleeve 18 is then forced through the passage 31 and is prevented from
returning by the valve 32. The air, mingled with the naptha, forms a gass
which passes into the chamber 23, and thence through the opening 25 to the
burner; the flow being regulated to the required amount by the needle valve 26.
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) In a device for removing paint and varnish from surfaces, and com-
prising a cylindrical reservoir, and a burner and scraper combined therewith
at one end; a plug fitted in the reservoir at its other end, a passage extending
through said plug; a valve normally closing said passage; a packing-ring
around said plug, a sleeve slidably fitted over the reservoir and made air and
liquid tight thereon by said packing ring; means such as lugs engaging grooves
in the sleeve to limit its travel over said reservoir and to retain the sleeve in
place; a spring interposed between the plug and a cap secured over the slidable
sleeve; all substantially as described and illustrated in the drawings hereunto
annexed.
(2) In a device for removing paint and varnish from surfaces, and comprising
a burner, a reservoir connected to the burner, and a scraper; the combination
therewith of a pump, comprising a passage entering the cylinder and normally
closed by an inwardly opening valve and the means for forcing air through said
passage into the reservoir, all substantially as and for the purposes hereinbefore
described and illustrated in the drawings hereunto annexed.
