Improvements in Morse Telegraph Apparatus.
We, SIEMENS BROTHERS & Co., LIMITED, of 12, Queen Anne's Gate, West-
minster, S.W., in the County of London, Electrical Engineers, do hereby declare
the nature of this invention (as communicated to us from abroad by Alberto
Tribelhorn, of National Telegraphs of the Argentine Republic, Buenos Ayres,
Telegraph Engineer,) 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 improvements in the Morse telegraph apparatus which
have for their object to prevent the ink from getting into and dirtying the
mechanism, as now frequently happens with ordinary Morse writers.
The improvements consist firstly in appliances for preventing the ink from
passing along the spindle of the writing disc so as to gain access to the internal
mechanism of the apparatus, and secondly to a modified construction of the ink
reservoir for preventing the ink from splashing over on to the external mechanism.
We will describe these improvements with reference to the accompanying draw-
ings, in which some of them are shewn applied, by way of example, to a particular
construction of Morse apparatus, but it is to be understood that they are equally
applicable to all other constructions. Figure 1 shews a front elevation of the
Morse writer with one arrangement of the ink apparatus applied thereto. Figure 2
is a plan. Figure 3 a part cross section, and Figures 4 to 10 show detached
details; Figures 11 and 12 shew other arrangements.
According to the arrangement shewn in Figures 1, 2 and 3, the toothed wheel n
of the clockwork which imparts rotary motion to the spindle of the writing disc c
is arranged outside the back plate of the casing, as is also the toothed wheel o on
spindle gearing therewith. The spindle 7 passes across the casing within a tube k
which extends through the casing at each end, being formed at the front end with
a flange secured to the casing by screws e as shewn at Fig. 5. The spindle is
supported at its rear end beyond the toothed wheel by means of a bracket B to
which is fixed the spring arm p into a slot in the upper end of which the spindle Z
fits with a neck u, as shewn in the detached view at Fig. 6; thus the spring arm p
serves both as a bearing to, and determines its longitudinal position, inasmuch
as by means of a regulating screw 9 screwing through and bearing against the
bracket B, the arm 7 can be adjusted to a more inward or more outward position,
thus shifting the spindle and writing disc longitudinally to a corresponding
extent.
It will be seen that by this means, the writing disc can be accurately adjusted
in position so as to correspond with the centre of the circular groove A of the
pressing roller. The above described construction also affords a ready means for
dismounting the writing disc and its spindle when required for any purpose.
The bracket B is secured to the casing by a clamping screw r passing through

page_text: an open alot in B, as shewn in the end view in Fig. 4, so that on loosening
the screw r, the bracket and spring arm p can be slid downward out of engagement
with the neck u of spindle 1. The toothed wheel o fits with a square hole in its
boss on the square end t, Fig. 6, of the spindle, so that when the support p is with-
drawn the wheel o can be drawn off the end of its spindle, and this, together, with
the writing disc c can now be drawn out at the front side.
It will be seen that by arranging the spindle within the tube k, the transmission
of any ink along the spindle to the interior of the apparatus such as frequently
occurs with the existing constructions, is effectually prevented.
Figs. 11 and 12 shew an arrangement for preventing the ink from passing along
the spindle to the interior of the machine, which consists in forming or fixing
upon the spindle, a cupped shield y, which has the effect of preventing any ink that
may run along the outer end of the spindle, from the disc c, from passing beyond
such shield, the ink being made to pass from the spindle on to the central portion
of the shield's outer surface, whence it flows to the periphery and then drips from
the forward sloping sharp edged rim thereof back into the ink vessel.
In the arrangement at Fig. 12, where the shield y is at a distance from the
writing disc c and near the casing of the machine, it is arranged within a funnel
shaped piece Z fixed to the casing, which guides the ink falling from the shield
back into the ink reservoir.
The latter is only indicated in dotted outline in Figs. 11 and 12 and may either
be of the construction to be presently described or of any known construction.
The ink reservoir shewn at Figs. 1, 2, 3 and 7, 8, 9 and 10, consists of two separate
parts f and g. f is the ink vessel proper, shewn in side view and plan at Figs. 9
and 10, and g is the under vessel or saucer, shewn in side view and plan at Figs. 7
and 8, this serves for intercepting any ink that may splash over the sides of the
vessel g.
This saucer is made with its upper edge sloping downwards towards the
front, as shewn, so that in the event of the saucer being allowed to become filled
with ink this will only drip out through the spout w Figs. 7 & 8, and it will
consequently be prevented from dirtying the casing and mechanism. The saucer g
has a slotted downward projection g¹ and is adjustably secured to the casing by
means of the clamping screw i; the ink vessel f rests with projections h and a upon
edges formed in the saucer.
This has a lip for convenience of handling.
As before stated, it is to be understood that the above described arrangements
for protecting the apparatus from becoming dirtied with ink, which alone form the
subject matter of the present invention, may be employed in connection with any
other construction of Morse apparatus.
Having now particularly described and ascertained the nature of this
invention and in what manner the same is to be performed, we declare that what
we claim is:-
-
1. In Morse telegraph apparatus, the herein described arrangement for prevent-
ing the internal mechanism from being dirtied with ink, which consists in enclos-
ing the spindle 7 of the writing disc in a tube k extending across the casing, the
gearing by which rotary motion is imparted to the spindle being arranged outside
the casing, substantially as described with reference to Figs. 1 to 6 of the drawings.
2. In Morse telegraph apparatus, the herein described arrangement for preventing
the internal mechanism from being dirtied with ink, which consists in fixing or
forming upon the spindle of the writing disc, a cup shaped shield y, which
serves to intercept any ink that may tend to creep along the spindle and to
cause it to drop back into the ink reservoir, substantially as described with
reference to Figs. 11 and 12 of the drawings.
3. Constructing the ink reservoir of a Morse telegraph apparatus of two separate
parts f, g, of which the upper vessel or cup f constitutes the ink reservoir and is
supported in the lower vessel or saucer g, serving to catch any ink escaping from
the cup f, which saucer has a rim inclined downward in the forward. direction

page_text: from the casing, and is provided at its lowest part with a spout w, substantially as
and for the purpose described with reference to Figs. 1 to 10 of the drawings.
