PROVISIONAL SPECIFICATION.
Improved Photograph-burnishing Machine.
I, JOHN PITT BAYLY, of 18 Fulham Place, Paddington, in the County of London,
Patent Agent, (a communication to me from abroad by William Entrekin of 4381
Main Street. Manayunk, Philadelphia, Pennsylvania, U.S.A., Photographer) do hereby
declare the nature of this invention to be as follows:-
This invention has for its object to provide a photograph burnishing machine having
a burnishing tool which is capable of being shifted in a direction transversely to the
action of the roll and thus bring a new burnishing surface into action when
required.
The machine comprises a fixed frame in the upper part of which the burnishing
tool is secured preferably in a groove. In the ends of the frame are pivoted midway
their length two side frames, in the upper ends of which is suitably journalled a
roller, and the opposite ends of which are provided with locking bolts. These locking
bolts engage suitable apertures in the ends of the fixed frame when the pivoted roll
carrying frames are swung over in such manner as to bring the roll over the burnishing
tool.
The bearings in which the roll is mounted, are supported upon suitable springs
which tend to keep the roll elevated above the burnishing tool. These bearings have
inclined upper faces, corresponding to inclined wedges joined by a rod, and running
in slots in the ends of the fixed frame. One wedge is provided at its end with a
threaded aperture in which engages the screwed portion of a stem free to turn, but
not free to move longitudinally in its fixed bearings. Two of these adjusting screws
provided with hand-wheels may be provided if desired, and serve to adjust the pressure
upon the photograph between the roll and the burnishing tool. By means of suitable
set-screws carried by the fixed frame and acting on the burnishing tool it may be
shifted in a transverse direction for the purpose herein before set forth.

COMPLETE SPECIFICATION.
Improved Photograph-burnishing Machine.
I, JOHN PITT BAYLY, of 18 Fulham Place, Paddington, in the County of London,
Patent Agent, do hereby declare the nature of this invention, (a communication to
me from abroad by William Entrekin, of 4384 Main Street, Manayunk, Philadelphia,
Pennsylvania, U.S.A. Photographer) to be as follows:-
One object of this invention is to so construct a photographic-burnishing machine
as to provide for readily bringing a new surface of the burnishing-tool into operative
position when desirable, a further object being to permit ready and unobstructed access
to all portions of the acting face of the burnishing-tool when it becomes necessary to
clean or repolish the same." These objects I obtain in the manner hereinafter set forth,
reference being had to the accompanying drawings, in which-
Figure 1 is a longitudinal section of a photograph burnishing machine constructed
in accordance with this invention.
Figure 2 is a transverse section of the same on the line 1, 2, with the side frame,
however, shown partly in elevation.
Fig. is a transverse section on the line 3, 4, Fig. 1, showing the feed-roll-carrying
frame adjusted so as to permit access to the burnishing-tool; and
Figs. 4 and
are views illustrating modifications of parts of the invention.

page_text: AA represent the opposite side frames of the machine, on which is mounted the
usual petticoat-bar B, carrying the burnishing-tool D, the upper face of which is
highly polished, so as to have a burnishing effect upon photographs fed across the same
by the action of the feed-roll F.
The petticoat-bar B has at its opposite ends projecting lugs a, which are seated upon
the fixed frames A of the machine, each of these lugs having a threaded opening b
for the reception of a threaded stem f, which is adapted to and free to turn in an
opening in the frame A, but is confined longitudinally to said frame by means of a
ping adapted to a groove in the stem, the outer end of the stem having a milled
head, by which it may be readily turned.
The upper or acting face of the barnishing-tool D is in a plane at right angles to a
radial line drawn through the point at which the roll F comes in contact with the card,
and the screw-stem provides for the adjustment of the petticoat-bar B and the
burnishing-tool in a plane parallel with the face of said tool.
The only portion of the face of the burnishing-tool which is operative in burnishing
is that part immediately beneath the bearing point of the feed-roll; hence if this
portion of the tool becomes rough or otherwise incapable of effecting the proper
burnishing of the photograph, a new burnishing-surface may be readily brought into
action by simply shifting the tool in one direction or the other by means of the screw-
stem f.
The burnishing-tool, however, is normally fixed during the operation of the machine,
and hence differs from those burnishing-tools which have a constant movement during
the burnishing operation, such constantly-moving tools being incapable of attaining
the object of this present invention, for any defect in a portion of the burnishing
surface of such a tool must necessarily be repeatedly brought into action during the
burnishing operation, whereas the sole purpose of the adjustment of the burnishing-
tool in the present machine is to remove such defective portion of the burnishing-surfaco
from an active position and thereby bring a new and perfect burnishing-surface into
action, so that when a batch of photographs is being burnished, the operation of
burnishing the entire batch can be completed without the necessity of stopping the
machine, and repolishing the burnishing-surface of the tool. In all photograph
burnishing machines, however, facilities must be afforded for repolishing the surface o!
the burnishing-tool at suitable intervals, and in order that ready and unobstructed
access may be had to all portions of the burnishing-surface of the tool, I adapt the
feed-roll of the machine to bearings carried by opposite side frames G, pivoted to
studs m on the fixed frames A of the machine, these studs being located some distance
below the top of the burnishing-tool, so that when the frames carrying the feed-roll
are swung around to a horizontal position, as shown in Fig. 3, all portions of said
frames and of the roll carried thereby are below the level of the upper or burnishing-
surface of the tool, so that the polishing of the same can be effected without difficulty.
When the roll-carrying frames G are adjusted to the vertical position, so as to bring
the feed-roll into operative relation to the burnishing-tool said frames are locked by
bolts n, which are carried by the frames G and are adapted to engage with openings p
in the fixed frames A of the machine, as shown in Fig. 1.
Although I prefer in carrying out this invention to use the threaded stems f
adapted to threaded openings in the lugs a of the bar carrying the burnishing-tool,
other means may be adopted for effecting the adjustment of said bar, if desired. For
instance, in Fig. 4 I have shown set-screws w, carried by the fixed frame A of the
machine, and bearing upon the opposite sides of the lug a for accomplishing the
purpose, or the bar inay be stationary and the tool adjusted laterally therein, if desired,
as shown, for example, in Fig. 5.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
1. The combination, in a photograph-burnishing machine, of the fixed frame, a
feed-roll, a burnishing-tool normally fixed in its relation to said roll, and set-screws

page_text: carried by the fixed frame and acting on the burnishing-tool, whereby said tool may
be shifted in a direction transversely to the action of the roll and a new burnishing-
surface thus brought into action when desired, substantially as specified.
2. The combination, in a photograph-burnishing machine, of the feed-roll, the
burnisher, and a fixed frame, said burnisher having threaded openings, and the fixed
frame having screw-stems adapted to said threaded openings, but confined longitudinally
to and free to turn in their fixed bearings, all substantially as specified.
3. The combination of the main frame and burnishing-tool of the machine, with a
feed-roll and opposite roll-carrying frames pivoted below the top of the burnishing-
tool, and having portions extending beyond the pivots and carrying locking-bolts
engaging with openings in the side frames, whereby, when the feed-roll is thrown
down, all parts of the carrying-frame are below the top of the tool, all substantially
as specified.
