PROVISIONAL SPECIFICATION.
Improvements in Devices for Oscillating the Baths or Tanks Used
for Photographic and other Purposes.
I, CHARLES MESSAZ, of Lausanne, in the Republic of Switzerland, Photographer,
do hereby declare the nature of this invention to be as follows:-
In the apparatus heretofore constructed with the object of oscillating the baths
or tanks used for photographic or other purposes, the liquid contained in the said
bath is oscillated to and fro, but not in a circular direction as is desirable in order
to enable the whole of the plate to be acted upon by said liquid.
By the use of my improved apparatus I am enabled to oscillate the bath both
in a to-and-fro and in a circular direction.
According to the present invention I provide a spring-motor which may be
wound up by means of a suitable key and which acts upon the apparatus by
means of suitable gearing, the speed of which is controlled by a fly-wheel, also
a vertical axis which traverses a fix guide-piece and bears a radially projecting
forked piece.
Vertically in line with the said vertical axis there is provided a bracket having a
hemispherical recess in which plays a spherical enlargement of a rod fixed to the
centre of the plate or table which is intended to carry the bath which is to be
oscillated. The lower end of the rod passes within the above-mentioned forked piece
and engages an elliptic groove of the fix guide-piece.
The plate or table is further provided with an eccentric pin projecting downwards
and engaging an eccentric hole of the bracket with the object of preventing the
rotation of the said rod.
The plate or table is provided with suitable projections of rubber, intended to
prevent the bath from sliding thereon when the latter is oscillated as will be herein-
after described.
From the above-described arrangement it will be seen that when the vertical axis
is rotated its radially projecting forked arm causes the lower end of the rod to
continuously circulate in the elliptical groove of the fix guiding-piece and as the upper
end of the said rod bears in a hemispherical bracket the plate or table will be oscillated
or moved in every direction.
Instead of being elliptic the groove may assume any other suitable shape or
configuration for the purpose of obtaining a suitable oscillation of the rod and the
plate or table.
Instead of being acted upon by means of a main-spring-barrel, the vertical axis may
be combined with any other suitable motor.
The herein described apparatus may be combined with a time piece for the purpose
of indicating the time during which the bath has been in motion.

for Photographic and other Purposes.
I, CHARLES MESSAZ, of Lausanne, in the Republic of Switzerland, Photographer,
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 :-
In the apparatus heretofore constructed with the object of oscillating the baths or
tanks used for photographic or other purposes, the liquid contained in the said bath
is oscillated to and fro, but not in a circular direction as is desirable in order to enable
the whole of the plate to be acted upon by said liquid.
By the use of my improved apparatus I am enabled to oscillate the bath both in a
to-and-fro and in a circular direction.
In the accompanying drawing
Figure 1 is a side-elevation of the whole apparatus showing some of the parts in
vertical section and
Figure 2 is a plan-view of a portion of the mechanism shown in Figure 1.
A is a spring-motor which may be wound up by means of a suitable key B and
which acts upon the apparatus by means of suitable gearing C, the speed of which is
controlled by a flyer D, also a vertical axis F which traverses a fix guide-piece E
and bears a radially projecting forked piece F¹. The arm X being intended to stop
the flyer by engaging an arm of the same.
Vertically in line with the said axis F there is provided a bracket G having
a hemispherical recess in which plays a spherical enlargement H of a rod I fixed to
the centre of the plate or table K which is intended to carry the bath to be oscillated.
The lower end of the rod 1 passes within the above-mentioned forked piece F and
engages an elliptic groove e of the fixed guide piece E.
The plate or table K is further provided with an eccentric pin L projecting
downwards and engaging an eccentric hole of the bracket G with the object of
preventing the rotation of the said rod I.
The plate or table K is provided with suitable projections k of rubber, intended to
prevent the bath from sliding thereon when the latter is oscillated as will be herein-
after described.
From the above-described arrangement it will be seen that when the vertical axis F
is rotated its radially projecting forked arm F¹ causes the lower end of the rod I to
continuously circulate in the elliptical groove e of the fixed guiding-piece E and as
the upper end of the said rod I bears in a hemispherical bracket the plate or table K
will be oscillated or moved in every direction.
Instead of being elliptic the groove e may assume any other suitable shape or
configuration for the purpose of obtaining a suitable oscillation of the rod I and the
plate or table K.
Instead of being acted upon by means of a main-spring barrel, as shown in the
drawing, the vertical axis F may be combined with any other suitable motor.
It is evident that the fixed guiding-piece E with elliptic groove e may at will
be dispensed with the lower end of the rod being then only guided by the forked
piece F fixed to the rotating axis and the eccentric pin L provided to the table may
engage a fixed fork instead of engaging a hole of the bracket.
The herein described apparatus may be combined with a time piece for the purpose
of indicating the time during which the bath has been in motion.

page_text: 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. A device for oscillating in every direction a bath or tank for photographic or
other purposes substantially formed of the combination of a motor of any kind acting
upon a vertical axis bearing a radially projecting forked arm with a plate intended
to carry the bath tank and having a downward projecting rod engaging the said
radially projecting forked arm of the rotating axis, a suitable projection being
provided to the said rod and engaging a hole or fork provided to a fixed portion
of the apparatus.
2. A device for oscillating in every direction a bath or tank for photographic or
other purposes substantially formed of the combination of a motor of any kind acting
upon a vertical axis bearing a radially projecting forked arm with a plate intended
to bear the bath or tank and having a downward projecting axis engaging the said
radially projecting forked arm of the rotating axis and a suitable groove of a fixed
guide-piece substantially as and for the purpose specified.
3. In a device for oscillating in every direction a bath or tank for photographic
or other purposes an oscillating plate K provided with rubber-projections & substan-
tially as and for the purpose specified.
