A. Device for enabling the Passage of a Weight or Parcel or any
other kind of Attachment along a Wire or Rope without being
Obstructed by the Supporting Pillars.
I, PALOORU SANKARANARAYANA, M.A., of 69, Swami Pillai Street, Choolay, Madras,
in India, retired Educational Officer, do hereby declare the nature of my invention for
"A device for enabling the passage of a weight or parcel or any other kind of attachment
along a wire or rope without being obstructed by the supporting pillars" to be as
follows: A pillar or post for supporting a rope, wire, or the like, extending over long
distances, is made as follows. The post divides at any required height into two
branches or arms, as in Fig. 1 in the accompanying drawing, or bends down either in
a curve or with angles, and then divides into two branches, as in Fig. 6. The two
arms of the post are surmounted with two peculiarly formed toothed wheels, of any of
the following descriptions and adjusted in the following manner. The wheels are
furnished with sufficiently long teeth and are in the same horizontal plane when
mounted. The teeth of each wheel extend into the intervals of those of the other.
All the teeth, again, are either (a) bifurcated in their thickness, i.c. in the vertical
direction, as shewn in Fig. 5, or (b) of smaller thickness for the whole or a part of
their lengths towards their ends, than the body of the wheel, as shewn in Fig. 3.
The wheels are mounted on the two arms of the post. In the case of the pillar of the
form represented in Fig. 1, a fixing nud connecting piece C D is put on the two arms.
In the case of the form represented in Fig. 6, the two arins will have, after the wheels
are put in, head pieces E F and G H of any kind, or washers and nuts, either
permanently attached or screwed to them, to keep the wheels in place and
support them.
When the wheels are of the description illustrated in Figs. 2 & 3,
they will be so placed as to have the depression in thickness upwards, i.e. their
surface KL upwards and M N downwards, both in the case of the pillar in
Fig. 1 and Fig. 6. The rope or wire to be supported passes between and through
the branches of the bifurcated wheel teeth in the case of the wheels represented
in Figs. 4 & 5, or passes upon the thinner parts of the teeth in the case of the
wheels represented in Figs. 2 & 3, and is supported by them. A weight or
parcel hanging from, or other object attached to, a wire supported as above, can
pass along the wire, notwithstanding and through the intervening pillars which
support the wire, when they are made as described above. As the hanging weight
or other object attached passes, the wheels revolve and make way for it, the teeth
in front of it moving round and the remoter ones gradually turning in from behind
it to take their place in supporting the wire.
In order to diminish the friction between the wire and the supporting teeth, each
tooth may be made round and sheathed in or surrounded by a hollow cylindrical
tube which would revolve under the wire.
When the wire to be supported goes from a lower to a higher level, the upper
portion of the pillar will be made of the required slant.
To facilitate the passing or getting of the hinder teeth under the wire as the

page_text: object passes forward, the teeth may be made slightly tapering towards the ends, or
furnished at the tips with pieces bent downwards.

A Device for enabling the Passage of a Weight or Parcel or any
other kind of Attachment along a Wire or Rope without being
Obstructed by the Supporting Pillars.
I, PALOORU SANKARANARAYANA, retired Educational Officer, of 69, Swami Pillai
Street, Choolay, Madras, India (now changed to Tutor to the Rajah of Pithapuram,
of Pithapuram, Godavery District, Madras Presidency, India), do hereby declare the
nature of my invention for "A device for enabling the passage of a weight or parcel
or any other kind of attachment along a wire or rope without being obstructed by
the supporting pillars," and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
A pillar or post for supporting a rope, wire, or the like, extending over long
distances is made as follows. The post divides at any required height into two
branches or arms, as in Fig. 1 in the drawing accompanying the Provisional
Specification, or bends down either in a curve or with angles and then divides into
two branches as in Fig. 6. The two arins of the post are surmounted with two :
peculiarly formed toothed wheels, of any of the following descriptions and adjusted in
the following manner. The wheels are furnished with sufficiently long teeth and are
in the same plane when mounted. The teeth of each wheel extend into the intervals
of those of the other. All the teeth, again, are either (a) bifurcated in their
thickness, i.e. in the vertical direction, as shown in Fig. 5, or (b) of smaller thickness
for the whole or part of their lengths towards their ends, than the body of the wheel,
as shown in Fig. 3. The wheels are mounted on the two arms of the post. In the
case of the pillar of the form represented in Fig. 1, a fixing and connecting piece CD
is put on the two arms. In the case of the form represented in Fig. 6, the two arms
will have, after the wheels are put in, head pieces E F and G H of any kind, or
washers and nuts, either permanently attached or screwed to them, to keep the
wheels in place and support them. When the wheels are of the description illustrated-
in Figs. 2 & 3, they will be so placed as to have the depression in thickness upwards,
i.e. their surface K 1, upwards and M N downwards, both in the case of the pillar
in Fig. 1 and Fig. 6. The rope or wire to be supported passes between and through
the branches of the bifurcated wheel teeth in the case of the wheels represented in
Figs. 4 & 5, or passes upon the thinner parts of the teeth in the case of the wheels
represented in Figs. 2 & 3 and is supported by them. A weight or parcel hanging
from or other object attached to, a wire supported as above, can pass along the wire,
notwithstanding and through the intervening pillars which support the wire, when
they are made as described above. As the hanging weight or other object attached
passes, the wheels revolve and make way for it, the teeth in front of it moving round
and the remoter ones gradually turning in from behind it to take their place in
supporting the wire.
In order to diminish the friction between the wire and the supporting teeth, each
tooth may be made round and sheathed in or surrounded by a hollow cylindrical
tube which would' revolve und the wire.
When the wire to be supported goes from a lower to a higher level, the upper
portion of the pillar will be made of the required slant.

page_text: To facilitate the passing or getting of the hinder teeth under the wire as the
object. passes forward, the teeth may be made slightly tapering towards the ends or
furnished at the tips with pieces bent downwards.
Drawings have been left with the Provisional Specification.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that
what I do claim is :-
The formation of a pillar or post, furnished with branches and mounted with
toothed wheels substantially as described above.
