page_text: I, WARREN HIGHLMAN BOLES residing at Syracuse, in the County of Onondago
and State of New York, one of the United States of America, Manufacturer, do hereby
declare the nature of this invention and in what manner the same is to be performed
to be particularly described in and by the following statement:-
This invention relates to machines for burnishing or polishing articles or materials
of various kinds, but more especially photographs, and described with special reference
to this class of machines my invention has for its object to economize the first cost of
manufacture; gain time in heating the burnishing tool, and save cost and labor in
heating make a durable and easily adjusted machine and one having readily re-
movable parts, avoid collection of soot and generally to remove objectionable features,
I meet with in such machines as have come under my notice in a long practical
experience in the use and sale of this class of goods.
:
The invention consists in a tubular or flue burnishing tool heated by a kerosene
or other cheap burning fluid lamp, or by gas, means for adjusting and removing
such tool; means for ascertaining and thereby regulating its temperature: means for
readily applying and removing the heater, and also a tubular ventilated feed roll, all
and severally as I will now proceed to particularly set forth and claim.
In the accompanying drawings in the several figures of which like parts are similarly
designated,
Figure, 1, is a front elevation of one form of my machine.
Figure, 2, a top view.
Figure, 3, is a bottom view of the burnishing tool detached.
Figure, 4, is a vertical section in the plane of line, -, figure, I, with the lamp
removed and,
Figure, 5, a vertical section on a larger scale in the plane of line, y-y, figure, 1.
The frame may consist of two upright castings, a, a, connected and braced by a table,
detachably bolted thereto, as indicated in figure, 3. The upper ends of these uprights
are provided with housings, c, c, for the journals of the feed roll, d, and this feed roll [
make hollow so as to ventilate it and thus prevent condensation of vapors thereon, thus
avoiding spoiling the picture or rusting the polishing tool.

page_text: The surface of this feed roll may be roughened or milled by means of a nurling tool
in a lathe to give it the necessary bite or friction upon the picture to advance it
regularly and uniformly over the burnishing tool. A hand crank, e, may be attached
to the feed roll to rotate it. The burnishing iool,, is located beneath the feed roll, and
consists of a tibular casting, having the polished, and if desired, nickel-plated surface, g
the projecting arms, h, at each end, which have tapped seats, i, which rest upon pivot
or fulcrum screws, j, arranged in screw threaded lugs, k, on the uprights, a, a.
These screws, by vertical adjustment in the lugs admit of the raising or lowering of
the burnishing tool with respect to the feed roll, and said screws may be set in such
adjustment by the lock-nuts, 1. The arms are connected by a rod, m, to prevent their
warping out of alignment with the screws.
On the opposite side of the burnishing tool, a central arm, n, projects out over the
table, b, and is provided with a temper screw, o, whereby the requisite pressure may
be given to the picture, said screw bearing or seating on the table to this end, and its
rotation in the arm, n, serving to move the burnishing tool as a lever upon its pivot
screws. This construction enables me to gain complete and instant control of the
pressure upon the pictures.
Obviously by lowering the arm, n, on its screw, o, the tool, f, may be readily
removed from the machine for repair, or cleaning, or replacement. Damage to and
loss of pictures are of quite frequent occurence in burnishers now commonly used
owing to the lack of provision for ascertaining and regulating the heat. In my
invention the burnishing tool is made hollow and open from end to end, holes, p, being
made in the uprights in alignment with the tool so as to obtain a through and through
passage. An opening, 7, is made in the lower part of the tool, about midway of its
length, and this opening has at one side a stationary fender, r, and at the other a hinged
fender or hood, s, and in this opening and between these fenders is received the
chimney, t, of an ordinary coal oil or other burning fluid lamp, u.
The hinged fender permits the ready insertion and removal of the lamp or heater.
The burnishing tool being hollow and open from end to end, a natural draft will be had
through it, and combustion will be stimulated and the rapid heating of the tool insured.
A thermometer, e, is applied to the burnisher in order to enable the operator to ascer-
tain and regulate the temperature of the burnisher. The wick of the lamp will be raised
and lowered to increase or diminish the volume of flame and heat according to the
indications of the thermometer. Some of the advantages of my invention are as
follows:-
1. There is never any possible danger of the picture being spoiled by the smoke
coming in contact with the face of the same as the smoke emerges within the flue, and
is carried off at the ends of the same by the draft.
2. The accumulation of soot under the burnishing tool is avoided by the draft
through the flue, which carries off all the smoke and thus saves the necessity of using
the fuel to heat the soot over and over again as is the case with all burnishers having
no draft.
3. The tension is even and invariable absolutely positive and alike on both ends, and
gained by leverage from one point and hence there is no possibility of the picture
running crooked or being twisted.
4. The heat can be graduated at command, by simply raising or lowering the wick
of the lamp, and can be accurately gauged by the thermometer, consequently the chance
of blistering or discoloring by getting the burnishing tool too hot is avoided.
5. My machine will burnish the cards equally as well on the edges as in the centre,
as the heat is uniformly distributed by the drafts created by the flues under the
burnishing tool drawing the heat uniformly from end to end of the tool.
6. The burnishing tool can be cooled much more rapidly than any other, as it is
only a hollow tube of metal, instead of a solid block of iron; hence if it is necessary to
remove the burnishing tool to remove a scratch from the face of same it can be readily
done without danger of burning.
7. The thermometer attached to the side of the flue will tell precisely what degree
of heat the burnishing tool has attained, consequently one is not compelled to remain

page_text: in doubt, and thus saves the necessity of defacing two or three pictures before ascer-
taining whether the burnishing tool is in proper condition for work.
8. There is no possibility of any moisture forming or condensing on the feed roll or
polishing tool during the process of heating, because the feed roll is made hollow its
whole length, thereby creating an air chamber through the centre of the same from
end to end, this positively avoids the serious danger of spoiling the polishing tool or
pictures by contact with such moisture.
Prior to my invention it has been customary to roughen the surface of feed or
pressure rollers by longitudinally serrating them by draw filing, but this is an expensive
operation.
I accomplish this roughening in a better and far more expeditious manner by the
use of a nurling tool in a lathe.
The invention herein is applicable to mangles and calendering machines.
Having now particularly described and ascertained the nature of the said invention
and in what manner the same is to be performed I declare that what I claim is :-
1. In a burnisher, a tubular burnishing or polishing tool, open from end to end and
having an opening to receive the chimney of the heating lamp and a hinged fender or
hood to permit ingress and egress of the lamp combined with such lamp, substantially
as described.
2. In a burnisher, a tubular burnishing or polishing tool open from end to end
and having an opening to receive the chimney of the heating lamp and a hinged fender
or hood to permit ingress and egress of the lamp and a stationary fender cooperating
with the hinged fender to inclose the upper end or outlet of the lamp chimney combined
with such lamp, substantially as described.
3. In a burnisher, a burnishing tool provided with fuleral arms, and adjustable pivot
or fulcrum screws on which said arms rest, and an intermediate temper screw,
substantially as described.
4. In a burnisher, the burnishing or polishing tool and a heater therefor, combined
with a temperature indicating device, such as a thermometer, substantially as
described.
5. In a burnisher, the tubular feed-roll, d, open from end to end to ventilate the
same, combined with a burnishing tool and means to heat the latter, substantially as
described.
6. The feed roll of a burnishing machine, the acting or feeding surface of which is
nurled, as distinguished from draw-filed, substantially as described.
