"An Improved Method of Driving Capstans, and the Working and
Travelling of Hydraulic Cranes and other Hydraulic Machinery."
I, JAMES HANNAN, of 106, Calder Street, Govanhill, in the County of the City
of Glasgow, North Britain, Mechanical Engineer, do hereby declare the nature of
this Invention to be as follows:-
This invention has for its object to provide a simple and efficient arrangement
for driving capstans and the working and travelling of hydraulic cranes and other
hydraulic machinery.
In carrying out my Invention I gear to the spindle upon which the drum or
barrel of the capstan revolves a worm wheel which gears with a worm on the
shaft of which there is carried a pelton wheel. The pelton wheel which is driven
by water power imparts motion to the worm it being carried on the same shaft
and this in turn communicates motion to the worm wheel which turns the spindle
on which the drum or barrel revolves. In some cases it may be necessary to pro-
vide two or more pelton wheels.
As an alternative arrangement, in place of the worm and wheel as described,
I might have a large wheel geared to the spindle of the drum or barrel which
gears with a pinion on which the pelton wheel or wheels is or are carried as
already described.
In applying my improvements to the working and travelling of hydraulic cranes
and other hydraulic machinery the gearing is arranged according to the require-
ments of each case.

"An Improved Method of Driving Capstans, and the Working and

I, JAMES HANNAN, of 106, Calder Street, Govanhill, in the County of the City
of Glasgow, North Britain, Mechanical 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:-
My Invention has for its object to provide a simple and efficient arrangement

hydraulic machinery.
In order that my Invention may be properly understood and readily carried
into effect I have hereunto appended one sheet of Drawings in both Figures of
which corresponding parts are marked with the same letters of reference.
Figure 1 is a view partly in section and partly in elevation of one method of
carrying out my Improvements.
Figure 2 is a similar view of an alternative arrangement.
In carrying out my Invention, I gear to the spindle A upon which the drum
or barrel B of the capstan revolves a worm wheel C which gears with a worm D
on the shaft E of which there is carried a pelton wheel F. The pelton wheel F
which is driven by water power imparts motion to the worm D, it being carried
on the same shaft and this in turn communicates motion to the worm wheel C
which turns the spindle A on which the drum or barrel B revolves as shown in
Figure 1.

As an alternative arrangement, in place of the worm and wheel as described, I
might have a large wheel G geared to the spindle A of the drum or barrel B
which gears with a pinion F carried on an independent shaft E upon which is
mounted a bevil wheel which gears with a bevil pinion mounted on same shaft
as the pelton wheel F is carried as already described as shewn in Figure 2.
The rim of the bevil wheel may be a gun metal ring with cast or cut teeth
bolted or otherwise secured to cast iron or cast steel nave and arms and rim.
In some cases it may be necessary or desirable to provide two or more pelton
wheels.
Of course it is to be understood that two or more jets can be used to save water
when performing light work, the tread being so arranged as to turn water on
to one, two, or more jets at will or it may be automatically arranged to consume
water somewhat in proportion to pull exerted or work done
In applying my improvements to the working and travelling of hydraulic cranes
and other hydraulic machinery the gearing is arranged according to the require-
ments of each case.
Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:
The method of driving capstans and the working and travelling of hydraulic
cranes and other hydraulic machinery, substantially as and for the purposes here-
in before described and illustrated on the accompanying sheet of Drawings.
