SPECIFICATION
Improvements in Hydraulic Organ Blowers.
I, ARTHUR WILLIAM SPEED, of Crescent Road, Sheffield, 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 improvements in "Hydraulic " organ blowers, and consists
in using a semicircular valve, spindle and connections whereby jerking at each end of
the stroke is effectually prevented.

DESCRIPTION OF DRAWINGS.
Fig. 1. is a side clevation shewing large cylinder and smaller cylinder
iments attached.
Fig. 2. is a plan of smaller cylinder as shown in Fig. 1.
Fig. 3. is an end elevation of Fig. 1.
Fig. 4. is a section of my improvements.
Figs. 5 and 6. are details of valve.

A is the large cylinder containing the usual piston and rod B for operating the
ordinary trace and feeder, is the smaller cylinder connected to the said larger
cylinder, in this smaller cylinder C is the ram working backwards and forwards, and
on the side of this cylinder is the disc face D in which are the port holes, G is the
exhaust, H, H the feed, and J, J two smaller holes which are bored into cylinder C,
making direct communication with K' and supplies the feed H, H. The semicircular
valve K works against the disc face D, and has a backwards and forwards semicircular
movement, the valve is within the valve cover K¹ provided with stuffing box K2. The
said valve K is attached to the spindle L which carries the lever M at its other end
and is connected by rod N and arm P or other suitable connections to the piston of
the cylinder or to the trace or feeder, the said rod N is provided with adjustable stops
for regulating the amount of movement of the spindle and valve.
The valve has a recess E upon its face which as it turns upon its spindle opens and
closes the feed port holes at each side alternately, also the top exhaust as required, so
effectually preventing jerking.
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 construction of valve and spindle for preventing jerking at each end of the
stroke substantially as shown and described.
