COMPLETE SPECIFICATION.
New or Improved Apparatus for Heaving Lines or Ropes.
I, WILLIAM TYREE, of 42 Lambton Quay, in the City of Wellington, in the
Colony of New Zealand, 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:-
The usual method of heaving lines or ropes by hand from ships or wharves is well
known and often proves to be a very uncertain and dangerous process.
Now by my invention I provide an apparatus which will project a line or rope by
mechanism, which can be set and regulated so as to give the necessary force and
direction so as to propel the line to any desired point.
My apparatus is illustrated on the accompanying sheet of drawings on
which,
Figure 1 is a side view, and
Figure 2 an end view of my apparatus.
Similar letters refer to similar parts in both the figures.
(a) is the deck of the ship or the platform on which the apparatus rests and is
fastened by a pin or bolt (6), on which bolt as a center the apparatus can be turned
or swivelled to direct the missile to the right or left as desired. (c) is a plate made
(preferably) of wrought iron which carries an upright, to which is attached an
upright rack or ratchet bar (c') for a purpose to be hereinafter described. (c²) is a
jaw or joint forming a part of or fastened to the plate (c), to which are hinged two
frames (d) stayed together at a short distance apart by stays (d') and resting by a
spring pawl (d) upon the teeth of the ratchet or rack (c'). It will be evident that
by this arrangement the frames (d) can move in the joint (c) whilst their opposite
ends can be raised or lowered by the spring pawl (d2). (e) is a standard or rod of
steel formed into a spiral spring at (e¹) so that it can be depressed into the position
shewn by the dotted lines and held in that position by a catch or trigger (f)
which has a hand rope (f¹) attached to it. On the outer extremity of this rod (e)
is fixed a plate (e²) fitted with a pin or hook (e³) to receive and hold loosely the
end of the line to be thrown, and which is generally provided with a weight or
ring (e¹). (g) are a set of blocks and falls to assist in lowering the rod (e) from its
position.
The action of my apparatus is as follows,-
The whole being held to the deck by the pin (6) and set at the desired position
to right or left according to the place to which it is required to throw the line, the
frames (d) are elevated in the rack (c) so as to be at the proper elevation to throw
the said line to the desired distance, the spring rod (e) is then drawn down to the
position shewn in dotted lines and fastened by the catch or trigger (f); the weight
or loop of the line to be thrown is then placed on the pin or ho k (3). When the
trigger or book (f) is pulled by the hand line (1) the rod (e) will throw the end
of the line (r) or anything attached to it to the spot for which the machine is set.
It will be evident that the rope (r) may be of any length. Moreover the rack or
ratchet (c¹) may be replaced by a rack and pinion, and the block and falls (g)
may be dispensed with and the steel rod (e) lowered by hand or other well known
means.

page_text: Having now particularly described and ascertained the nature of this inver-
tion and in what manner the same is to be performed, I declare that what I
claim is,
The apparatus for throwing lines or ropes as and for the purposes substantially
as described herein and illustrated on the accompanying drawing.
Dated this 3rd day of October 1895.
