PROVISIONAL SPECIFICATION.
Improved Means for Operating Hydraulic Hoists or similar
Appliances.
I, WALTER PHILLIPS, of 108, Fenchurch Street, in the City and County of
London, Marine Engineer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to improved means for operating hoists, generally known as
"hydraulic hoists," or hydraulic presses, in which the power is transmitted by the
medium of a fluid which acts upon a ram situated within a cylinder.
A convenient form of hoist is that in which a rope or chain is arranged around
pulleys situated upon the cylinder or frame attached thereto, and the head of the
ram respectively, so that upon the movement in or out of the ram in its cylinder, the
rope is slacked out and drawn in respectively. This is known as a multiple ram.
This appliance is particularly applicable to small hoists usually employed upon
steamers for the purpose of raising the ashes from the stoke-hold to the deck or for
other purposes. Up to the present time it has been usual to work ash hoists from
the hydraulic accumulator or hydraulic pumps belonging to the main hydraulic
installation of the ship. This is at times very inconvenient, as circumstances often
are such, that only one boiler is required to be kept under steam, consequently
should the ashes from this one boiler require to be hoisted, the whole of the main
hydraulic plant has to be set in operation.
My invention has for its object the obviation of this inconvenience and consists in
operating the hoist by water pressure obtained from the boiler.
It is obvious that wherever small hoists or hydraulic presses are required in
situations other than on board ship, should boiler power be available, my improved
arrangement will be equally applicable.
This I carry out by connecting the hoist with the lower part of the boiler, so
that when the controlling valve to the hoist or press is opened, the pressure in the
boiler will force out some of the water contained therein into the hydraulic ram and
operate the same. The water used may be returned to the condenser of the main
engines or to a separate tank, and be pumped back into the boiler, so that there is
practically no actual loss of boiler feed.
Dated this 5th day of September 1890.

COMPLETE SPECIFICATION.
Improved Means for Operating Hydraulic Hoists or similar
Appliances.
I, WALTER PHILLIPS, of 108 Eenchurch Street, in the City and County of
London, Marine 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 relates to improved means for operating hoists generally known as
hydraulic hoists or hydraulic presses in which the power is transmitted by the
medium of a fluid which acts upon a ram situated within a cylinder.
A convenient form of hoist is that in which a rope or chain is arranged around
pulleys situated upon the cylinder or frame attached thereto and the head of the

page_text: ram respectively so that upon the movement in or out of the ram in its cylinder the
rope is slacked out and drawn in respectively. This is known as a multiple ram.
This appliance is particularly applicable to small hoists usually employed upon
steamers for the purpose of raising the ashes from the stoke hold to the deck or for
other purposes.
Up to the present time it has been usual to work ash hoists from the hydraulic
accumulator or hydraulic pumps belonging to the main hydraulic installation of the
ship. This is at times very inconvenient, as circumstances often are such, that only
one boiler is required to be kept under steam, consequently, should the ashes from
this one boiler require to be hoisted the whole of the main hydraulic plant has to be
set in operation.
My invention has for its object the obviation of this inconvenience, and consists
in operating the hoist by water pressure obtained from the boiler.
It is obvious that wherever small hoists or hydraulic presses are required in
situations other than on board ship, should boiler power be available my improved
arrangement will be equally applicable.
This I carry out by connecting the hoist with the lower part of the boiler so
that when the controlling valve to the hoist or press is opened the pressure in the
boiler will force out some of the water contained therein into the hydraulic rain and
operate the same. The water used may be returned to the condenser of the main
engines or to a separate tank and be pumped back into the boiler so that there is
practically no actual loss of boiler feed.
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 claim is :-
1st. An improved means for operating hydraulic hoists or presses by putting the
cylinder or cylinders of the same in communication with the water space of a steam
boiler under pressure.
2nd. An improved apparatus for exerting hydraulic power consisting of a steam
boiler, a hydraulic cylinder and ram connected to the water space of the said boiler,
a tank or condenser connected to the exhaust pipe of the said hydraulic cylinder,
and a pump connected to the said tank or condenser and to the boiler, to return the
water used in the hydraulic cylinder to the boiler again.
