AN IMPROVED STEAM AND HAND POWER NET AND OTHER HAULING MACHINE
Year: 1885

I THOMAS CAIN of The Lake" Douglas, Isle of Man, Engineer do hereby
declare the nature of my said Invention for AN IMPROVED STEAM AND HAND
POWER NET AND OTHER HAULING MACHINE to be as follows:-
This Invention relates to that class of net and like hauling machines in which
sheaves or surging heads (pullies) are arranged on the outside of a frame and
exposed, which frame can be moved in a circular direction to accomodate itself to
the line of haulage, the gear being within a double casing.
According to the ordinary method of driving these machines by hand the pinion
on the hand wheel shaft, gears into one of the end wheels, and this answers very
well when the hauling is in one direction, but it is inconvenient and occasions loss
of power when the hauling is on to the sheave at the opposite end.
According to the first part of my invention, I fit my hand driving shaft in the
centre of the framing, and well up, and I actuate the middle of the three hauling
drums by an intermediate gear, and by that means obtain a decided advantage
both in power and also from the position greater facilities of hauling from either
end of the frame.
The gear is of the ordinary construction, and on the shaft of the centre sheave
I arrange a bevil wheel with a clutch so that it may be driven by steam power
from below the deck to the right, or to the left, according to the haulage desired
and by clutch and bevil gear fitted in connection therewith, and with a vertical
shaft which passes up through a socket plate, fixed on the deck, said socket plate
at the upper part forming a bed on which the framing can be moved round. The
lower part of said framing is formed with a broad circular base, and is provided
with notches into which pauls can be dropped (into a catch plate) upon the socket
bedplate to fix the frame temporarilly in any position, but worm or other gearing
may be arranged for this purpose as desired.
The clutch is so arranged that the bevil wheels of the steam power, driving shaft
and bevil wheels in the body of the frame may be put out of gear, when the
haulage has to be effected by band, and by shifting the clutch the hauling drums
may be driven in either direction..
The sheaves may be interchangeable with chain sheaves or such as the hauling
requires and when using two or three sheaves a rim of cogs is cast on each sheave
(gearing into each other) with a cover over the cogs to protect them from injury
18 well as preventing the rope becoming entangled therewith.

An Improved Steam and Hand Power Net and other Hauling
Machine.
I THOMAS CAIN of "The Lake," Douglas, Isle of Man, 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:-
This invention relates to that class of net and like hauling machines in which
sheaves or surging heads (pullies) are arranged on the outside of a frame and
exposed, which frame can be moved in a circular direction to accomodate itself to
the line of haulage, the gear being within a double casing.
According to the ordinary method of driving these machines by hand, the pinion
on the hand wheel shaft, gears into one of the end wheels, and this answers very
well when the hauling is in one direction, but it is inconvenient and occasions loss
of power when the hauling is on to the sheave at the opposite end.
According to my invention which will be clearly understood by the annexed
drawings of which Figures 1 and 2 are an elevation and plan respectively of a
hand machine, I fit my hand driving shaft A in the centre of the framing B and
well up as shown at Figure 1. The pinion O on this shaft actuates the middle 1)
of the three hauling drums D E F by an intermediate gear G. By that means
I not only obtain a decided advantage in power but from their positions great
facilities for hauling from cither end of the frame.
For power driving net hauling machine I fit on the shaft H of the centre
sheave Da bevil wheel I to engage in a bevil pinion J on a vertical shaft K so that
the machine is driven from below the deck to the right, or to the left, according
to the haulage desired through the clutch L and bevil gear M fitted in connection
therewith as shown at Figure 3. The vertical shaft K passes up through a socket
plate N fixed on the deck P said socket plate N at the upper part forming a centre
post N¹ and a bed, about and on which the framing B B¹ can be moved round.
The pedestal or lower part B₁ of said framing B is formed with a broad circular
base Q, and is provided with notches into which pauls R can be dropped to fix
the machine temporarilly in any position, but worm or other gearing may be
arranged for this purpose as desired.
The clutch is so arranged that the gear may be put out of action, and by
shifting the clutch to the desired pinion the hauling drums may be driven in
either direction. This power driving Net Hauling Machine may be operated by
hand by fitting a crank handle on the shaft A.
The sheaves may be interchangeable with chain sheaves or such as the hauling
requires, and the sheaves may each have a rim of cogs cast on them to gear into
each other with a cover over the cogs to protect them from injury as well as to
prevent the rope becoming entangled therewith.
The shaft of the middle sheave may project through from the back of the
frame B and have affixed to it a drum or sheave S as at Figure 4.

page_text: Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what
I claim is
1. In a hand power net or like hauling machine, the particular arrangement of
gear for driving the middle one of three sheaves from an intermediate pinion as
described and shown.
2. The particular arrangement of pedestal frame for carrying the gear and
hauling drums, said frame having a notched plate as and for the purpose described.
3. In an alternative hand or steam power net or like hauling machine the
particular arrangement of appliances herein described and as shown at Figures 3
and 4 of the annexed drawings, the power being always given to the outer sheaves
from the middle one as set forth.
4. In a net or like hauling machine the centre post N¹ on and about which the
pedestal frame B B¹ has motion to suit line of haulage as described.
