page_text: LETTERS PATENT to John Sampson Starnes, of the Firm of J. S. Starnes and
Sons, of Broad Street, Ratcliff, in the County of Middlesex, Engineers and
Steam Ship Furnishers, for the Invention of "IMPROVEMENTS IN APPARATUS
FOR TRANSMITTING AND RECEIVING SIGNALS, ORDERS, OR MESSAGES FOR USE
ON BOARD STEAM AND SAILING SHIPS, AND IN MINES, BUILDINGS, AND OTHER
DEL"
Sealed the 2nd December 1879, and dated the 6th June 1879.
PROVISIONAL SPECIFICATION left by the said John Sampson Starnes at the
Office of the Commissioners of Patents on the 6th June 1879.
JOHN SAMPSON STARNES, of the Firm of J. S. Starnes and Sons, of Broad Street,
"IM-
Ratcliff, in the County of Middlesex, Engineers and Steam Ship Furnishers.
PROVEMENTS IN APPARATUS FOR TRANSMITTING AND RECEIVING SIGNALS, ORDERS,
OR MESSAGES FOR USE ON BOARD STEAM AND SAILING SHIPS, AND IN MINES,
BUILDINGS, AND OTHER PLACES."
This Invention relates to such apparatus for signalling as are constructed with a
"transmitter" and an "indicator," connected at any distance apart by a single
flexible connection passing round suitably disposed guide pullies or bell cranks.
The object of my Invention is to render such telegraph apparatus more efficient by
the introduction and use within the indicating part or case containing or forming
the indicator of improved and more reliable gear for striking the alarm gong with
which such apparatus is provided.
This Invention consists in so constructing, arranging, and disposing the parts of
the "indicator" that the alarm gong and all the necessary striking gear are brought
within or into the casing which carries the two pullies, over which the transmitting
and repeating flexible connection passes. The central spindles carrying these
pulley wheels has fixed upon it a wheel provided with teeth, or instead thereof the
pulley wheels may be so provided with teeth, and a plate or bracket secured by
bolts or otherwise has on its surface two studs. Each of these studs carries a lever
piece forming a double hammer or hammer with two striking ends for sounding
the gong. The centre of each such lever piece, or that part by which the stud
carries it, is provided with a single tooth. The lever pieces are secured on their

page_text: studs, not rigidly, but so as to have a certain amount of play or motion on the
studs. The plate or bracket herein before mentioned has also four other studs, that
is to say, one for each striking end of the lever pieces or double hammers. On
each of these four studs last named is a helical spring, each such spring being pro-
vided with a projection or contact piece to be operated on by the hammer. Upon
the central spindle being rotated by the motion imparted by the flexible connection
between the "transmitter" and "indicator," the teeth of the wheels will as they
pass round engage with the single tooth on lever hammer, pressing it close against
the stud, on which it is fitted loosely, causing one of the ends of such lever haminer
to come in contact with the projection or contact piece of the spring, which by
being thus extended or compressed, as may be arranged, after causing the hammer
to give a sharp clear ring on the edge or rim of the gong, will return the hammer
to its original position. The striking gear just described is so arranged as to come
within or inside the gong. The number of hammers, springs, and studs may be
varied so long as the nature of the arrangement for striking the gong be main-
tained.

the said John Sampson Starnes in the Great Seal Patent Office on the 6th

JOHN SAMPSON STARNES, of the Firm of J. S. Starnes and Sons, of Broad Street,
Ratcliff, in the County of Middlesex, Engineers and Steam Ship Furnishers. "IN-
PROVEMENTS IN APPARATUS FOR TRANSMITTING AND RECEIVING SIGNALS, ORDERS,
OR MESSAGES FOR USE ON BOARD STEAM AND SAILING SHIPS, AND IN MINES,
BUILDINGS, AND OTHER PLACES."
This Invention relates to such apparatus for signalling as are constructed with
a "transmitter" and an "indicator," connected at any distance apart by a single
flexible connection passing around suitably disposed guide pullies or bell cranks.
The object of my Invention is to render such telegraph apparatus more reliable and
efficient by the introduction and use within the indicating part or case containing
or forming the indicator of improved or more reliable gear for striking the alarm
gong with which such apparatus is provided.
This Invention consists in so constructing, arranging, and disposing the parts of
the "indicator" that the alarm gong and all the necessary striking gear are brought
within or into the casing which carries the two pullies, over which the transmitting
and repeating flexible connection passes. The central spindle carrying these pulley
wheels has fixed upon it a wheel provided with toeth, or instead thereof the pulley
wheels, or one of them, may be provided with teeth, and a plate or bracket,
secured by bolts or otherwise, has on its surface two studs. Each of these studs
carries a lever piece forming a double hammer with two striking ends for sounding
the gong. The centre of each such lever piece, or that part by which the stud
carries it, is provided with a single tooth. The lever pieces are secured on their
studs, not rigidly, but so as to have a cortain amount of play or motion on the
studs. The plate or bracket hereinbefore mentioned has also four other studs, that
is to say, one for each striking end of the lever pieces or double hammers. On
each of these four studs last named is a helical spring, each such spring being
provided with a projection or contact piece to be operated on by the hammer.
Upon the central spindle being rotated by the motion imparted by the flexible
connection between the "transmitter" and "indicator," the teeth of the wheels
will as they pass engage with the single tooth on lever hammer, pressing it close
against the stud, on which it is fitted loosely, causing one of the ends of such lever
hammer to come in contact with the projection on contact piece of the spring,
which by being thus extended or compressed, as may be arranged, after causing
the hammer to give a sharp clear ring on the edge or rim of the gong, will return
the hammer to its original position. The striking gear just described is so arranged
as to come within or inside the gong. The number of hammers, springs, and studs
may be varied, so long as the nature of the arrangement for striking the gong be
maintained.
The Drawing accompanying this Specification shows the arrangement herein
above alluded to, having the teeth on pulley wheel. Figure 1 is an outside view,
showing the signals for an engine room telegraph of steam ship; Figure 2 is a view
of the working parts with the cover removed; and Figure 3 is a side sectional
view of the said working parts of "indicator." a is the central spindle carrying
the pulley wheels b, b², the latter b¹ having upon it the teeth c for actuating the
hammers, whose striking ends are marked d. The carrying plate or bracket is
marked, and the studs thereon g, carrying the double ended hammers & for
triking the gong h; the spring connected with hammer is marked j; the single
oose tooth herein above alluded to is marked i.
Figure 4 in the Drawings shows an arrangement for transmitting motion by
neans of hollow shafting operated by toothed gearing, the external shaft trans-
nitting the signals from one end to the other end, the internal arrangement being

page_text: used to give the reply, the internal shaft carrying a mitre wheel within the circum-
ference of the external wheel, as shown in the Drawing.
What I claim as my Invention and desire to secure by the hereinbefore in part
recited Letters Patent is, the construction of the striking gear, as shown in Figures
2 and 3, and in this Specification described, and its use in connection with the
transmitting and replying arrangements, as also herein in this Specification described
and alluded to.
In witness whereof, I, the said John Sampson Starnes, have hereunto set my
hand and seal, this Sixth day of December, in the year of our Lord One
thousand eight hundred and seventy nine.
