page_text: I OLIVER WHITE of 10 Tancred Road Anfield, in the County of Lancaster,
Engineer, do hereby declare the nature of this invention to be as follows:-
The invention relates to telegraphs used on shipboard for signalling from tho
bridge or other convenient part to the engineer or attendant in charge of the
engines, and for giving return signals."
The object is to so construct such telegraphs that when an order is given say
from the bridge to the engine room the engineer will not be able to signal that the
order has been obeyed without first bringing the engines to rest or causing them to
move in the required direction; and further that the fact of causing the engines to
move in the required direction will be indicated, and at the same time leave the
engineer at liberty to telegraph to the bridge the speed at which the engines are
moving.
The invention consists essentially in combining with telegraph signal and return
signal apparatus of any usual or ordinary construction appliances so connected to
the reversing gear or like part of the engine by means of a catch, clutch, or other
suitable device that the return signalling apparatus cannot be actuated except to a
limited extent without first giving the requisite motion to the reversing gear or
like part, and at the same time motion given to the said reversing gear will actuate
to a limited extent the return signalling apparatus.

page_text: I, OLIVER WHITE of 10 Tancred Road, Anfield, in the County of Lancaster
Engineer 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:—
The invention relates to telegraphs used on shipboard for signalling from the
bridge or other convenient part to the engineer or attendant in charge of the
engines and for giving returning signals.
The object is to so construct such telegraphs that when an order is given say
from the bridge to the engine room, the engineer or attendant will not be able to
signal that the order has been obeyed without first in compliance with the order
given, either bringing the engines to rest or causing them to move in the required
direction. A further object being to arrange the apparatus to indicate whether the
engines are at rest or are moving in the required direction and at the same time
permit the engineer to telegraph to the bridge the speed at which the engines are
moving.
The invention consists essentially in combining with telegraph, signal and return
signal or reply apparatus of any usual or ordinary construction appliances so con-
nected to the reversing gear or like part of the engine by means of a catch, clutch,
or other suitable device that the return signalling apparatus cannot be actuated
except to a limited extent without first giving the requisite motion to the reversing
gear or like part and at the same time motion, given to the said reversing gear will
actuate to a limited extent the return signalling apparatus.
The annexed drawing illustrates generally the construction and combination of
parts required to carry my improvements into effect, of course the particular
construction, arrangement and disposition will be varied to suit each individual
case, a. signalling apparatus of usual construction situated on the bridge or in
any other convenient position b. return signal or reply apparatus also of
usual construction located. in the engine room or near the engineer or attendant.
c. engines and reversing gear. The reversing gear c is connected by means of a
link d. to an arm e. provided with a pin f. which passes through a slot g. on a
pulley h. the arme and pulley h are free to rotate on the stud i Around the
pulley h. one of the connecting wires j. from the return signalling, or reply
apparatus b passes. The parts e. f. g. h. and i constitute the catch or clutch under
my invention.
The action of the apparatus is as follows:-Supposing the engines to be at rest
and the signalling and reply apparatus and the clutch in the position shown and
that a signal is given to move ahead or astern it will be obvious that until the
engineer or attendant has moved his reversing gear into the required position he
can only reply that the order has been heard as the motion of the reply apparatus
is limited to the extent of motion allowed to the pulley h. by the pin f. in the
Blot g. It is therefore impossible for the engineer or attendant to reply that the
order say for slow, half, or full speed ahead or astern, has been complied with,
until he has moved his gear into the required position. Numerous connections

page_text: between the pulley h. and arm e. may be made which will have desired effect
of allowing the pulley h. to have a small amount of motion independent of the
arm . and other well known or suitable devices may be substituted for the pulley
and arm.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, I declare that what
I claim is
First. The improvements in Ships telegraphs, herein set forth.
Second The combination with signalling and return signalling or reply
apparatus of clutch or equivalent mechanism connected to the reversing gear
substantially as set forth.
Third. Combining with Ships telegraphs and reversing gear the arm e. pin f.
slot g. pulley h. and stud i. or equivalent devices, for the purpose set forth.
