AN AUTOMATIC HYDRAULIC ORGAN BLOWER
Year: 1885

page_text: We, JOSEPH CLARKSON 196 High St. Pendleton, Manchester Professor of Music,
and THOMAS CLARKSON 196 High St Pendleton Manchester Student do hereby
declare the nature of the above invention for AN AUTOMATIC HYDRAULIC ORGAN
BLOWER, to be as follows:-
The object of this invention is to provide at a small cost a machine which will
be thoroughly efficient in working and most economical in the use of water. It
being so constructed that the same machine may be used for either a large or small
organ with the greatest efficiency & economy in the use of water without any
additional expense whatever in adapting it to the different instruments.
The Machine consists of a Vertical Ram or plunger, round at each end and
square in the middle; each end of the Ram works in a cylinder made in the form
of a pump barrel; Both ends of the Ram being of the same size, the same quantity
of water is used at each end of the ram, which is not the case when an ordinary
cylinder with a piston and piston rod are used.
We will suppose the ram to be at the end of the downward stroke. The water
is admitted into a chamber resembling an ordinary steam chest with valve and
valve-spindle, such as is used on a Steam Engine; this chamber is fixed on a block
(containing 3 ordinary ports) on the general framework of the Machine; the bottom
port being open, the water is conveyed through a pipe into the lower cylinder and
forces up the ram. When the ram has travelled nearly to the end of the stroke, or
as much of the stroke as is necessary; the position of the valve becomes reversed
by means of levers and tappets which are worked by a small bracket fixed on the
square portion of the ram; the top port now being open the water is conveyed
into the upper cylinder & forces down the ram; the water in the lower cylinder
being forced back through the same pipe by which it entered, finds its way out at
the exhaust port, and the valve being again reversed in the manner described
above, the ram again makes the upward stroke.
In the square portion of the ram is a vertical slot through which passes a strong
Horizontal lever, binged on to the ram by means of two vertical links and two
Horizontal pins. At one end of the lever are a number of holes, through one of
T •

page_text: which a round pin passes, on which the lever oscillates. This pin is screwed into a
bracket fixed to the general framework of the Machine and containing a corre-
sponding number of holes. The object of these holes is, that the pin on which the
Horizontal lever oscillates may be removed at pleasure to any one of them, and as
the distance between this pin and the ram is increased or decreased so is the power
of the Machine at the other end of the lever increased or decreased, and the length
of stroke of the ram may be increased or decreased accordingly so as to adapt the
Machine to all its requirements, and also to economise and utilise the power of the
Machine to the best advantage.
On the other end of the Horizontal lever is fixed a vertical connecting rod,
which is connected, with the bellows handle.
The clauses claimed in this invention are
Firstly-That by which the same quantity of water is used at each end of the
ram; and secondly That by which the power of the Machine may be regulated
by means of the Horizontal lever and Bracket containing holes and moveable pin.

THOMAS CLARKSON, (Student) 54 Roseneu Rd Albert Bridge, Battersea, London S. W.
late of 196 High St. Pendleton, Manchester, we do hereby declare the nature of
our invention for AN AUTOMATIC HYDRAULIC ORGAN BLOWER, and in 'what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:—
The object of this invention is to provide at a small cost a Machine which will
be thoroughly efficient in working and most economical in the use of water. It
being constructed so that the same Machine may be used for either a large or small
organ with the greatest efficiency and economy in the use of water, without any
additional expense whatever in adapting it to the different instruments.
The Machine consists of a vertical ram or plunger (a) fig. 2, with round ends,
each of which work in cylinders (b & c) fig. 2 made in the form of pump Barrels.
Both ends of the ram being of the same size, the same quantity of water is used at
each stroke of the Machine, which is not the case when an ordinary Engine
Cylinder is used, with piston and piston rod.
We will suppose the ram to be at the end of the downward stroke. The water
is admitted at the inlet (d) fig. 2. in Valve Box and conveyed into the lower
cylinder (c) fig. 2 and forces up the ram. When the ram has travelled nearly
to the end of the stroke, or as much of the stroke as is necessary, the position
of the Valve in Valve Box becomes reversed by means of rods and tappets,
which are worked by a small bracket fixed on the side of the ram. The
water is now conveyed into the upper cylinder (b) fig. 2. and forces down the
ram, the water remaining in the lower cylinder being discharged at the exhaust
port (e) fig. 2.
In the centre of the ram is a vertical slot, through which passes a strong Hori-
zontal lever (f) fig. 1. hinged on to the ram by means of a horizontal pin. One
end of this lever oscillates on a round pin or stud (g) fig. 1. which is fixed in a
slotted bracket (h) fig. 1. cast on the general framework of the Machine. This
pin (g) may be removed at pleasure nearer to or farther from the ram; and as the
distance between this pin and the ram is increased or decreased; so is the power of
the Machine at the other end of the lever increased or decreased; and the length
of stroke of the ram may be increased or decreased accordingly so as to adapt the
Machine to all its requirements, and also to economise and utilise the power of the
Machine to the fullest advantage.
On the other end of the Horizontal lever (which may be any length) is fixed a
Vertical connecting rod which is connected with the bellows handle of the Organ.

page_text: Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is
1. To use the same quantity of water at each stroke of the Machine, by means of
the ram and two cylinders.
2. To regulate the power of the Machine, by means of the Horizontal lever and
moveable pin.
