Improvements in and relating to Photographic Retouching Devices.
I ALBERT STAIR HARRY, a citizen of the United States of America, residing
at No. 405 Market Street, in the City of Steubenville, County of Jefferson and
State of Ohio, one of the United States of America, Gentleman, 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 a photographic retouching device.
The object of the present invention is to produce a mechanical retouching device..
which may be readily adjusted to make heavy or light blows, and which may be
manipulated with perfect ease and accuracy to retouch any part of the plate to.
eliminate blemishes or imperfections.
The invention consists in a retouching device comprising a suitable rocking hand
piece, an electro-magnet carried thereby, a stylus movably connected with the
hand piece and adapted to be projected by the armature of the said magnet, springs
for retracting said stylus, and side plates secured to the hand-piece.
In the accompanying drawings, forming a part of this Specification, and in which
like letters and numerals of reference indicate corresponding parts
Figure 1 is a side elevation of the device with the sides removed, showing the
manner of its use.
Figure 2 is a view of one of the sides.
Referring to the drawings, A, designates the hand piece, consisting of a frame, 1,
and side plates or covers, 2, which parts are to be made of any suitable material
but preferably of gutta percha. The hand piece is formed in this instance with a
curved base, 3, and rear wall, 4, a straight front wall, 5, and an angular top, 6;
but, if desired, the configuration may be changed or modified to suit different
requirements.
Within the frame and to the base 3, is secured an electro-magnet, B, one of the
wires, 7, of which is coiled about a set screw, 8, the other wire, 9, being suitably con-
nected with a metallic tip, 10, forming one of the pair of metallic tips to which the
conducting wires, 11, are secured. The conducting wires, 11, may be connected
with any suitable source of electric supply, an ordinary battery being all that is
necessary in most instances. To the other tip, 12, is connected one end of a leaf
spring, 13, which is held in place in the frame by means of a screw, 14, and nut, 15,
and carries the armature, 16. The free end of the spring is bent upward and
outward and bears against the set screw, 8, which latter, by being moved her up
or down will increase or diminish the vibrations of the armature, a jam-nut, 17,
carried by the set screw, serving to hold the latter at the desired adjustment.
The free end of the armature carries a weight or hammer, 18, which works
through a slot, 19, in the front wall of the hand piece, and is designed to engage
with the upper surface of a projection, 20, working in said slot and carried by a
stylus, C, which latter is free to reciprocate in guides, 21, carried by the hand-
piece, or, if desired, the weight may be dispensed with and the armature extended
to engage the projection, 20. The stylus shown in this instance is an ordinary
pencil holder of the "Faber" type, but any other form may be adopted that will
meet the requirements of the case. The under surface of the projection 20 is
engaged by a spring, 22, which exerts pressure upwards and returns the stylus
o its normal position after having been projected downwards by the hammer, 18.
The different parts of the device having been described, an explanation of its
operation will be given.
The parts being assembled and the current supplied to the magnet, the device is
aken in the hand, as shown in Figure 1, with the base. 3, resting upon the negative

page_text: to be retouched. The point of the stylus is now brought over the imperfection in
the plate, and by rocking the hand piece forward, the point is caused to contact
with and remove the imperfection in a manner that will be obvious. It will be
clear that this device may be made to do more rapid; accurate, and satisfactory
work than is possible to be done by hand.
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 :-
A retouching device comprising a suitable hand-piece provided with a curved
base whereby it may be rocked, an electro-magnet, supported in said hand-piece, a
stylus projected by the armature of said magnet, a spring for retracting said stylus,
and side plates secured to said hand-piece to cover and protect the magnets and
armature, substantially as herein described.
