IMPROVE- MENTS IN OIL FEEDERS
Year: 1879

page_text: LETTERS PATENT to George Butler and Richard Askie, Engineers, of Monnow
Road, Bermondsey, in the County of Surrey, for the Invention of "IMPROVE-
MENTS IN OIL FEEDERS."
Sealed the 4th June 1880, and dated the 8th December 1879.
PROVISIONAL SPECIFICATION left by the said George Butler and Richard
Askie at the Office of the Commissioners of Patents on the 8th December
1879.
GEORGE BUTLER and RICHARD ASKIE, Engineers, of Monnow Road, Bermondsey,
in the County of Surrey. * IMPROVEMENTS IN OIL FEEDERS."
"
Our Invention has for its object improvements in oil feeders, which by an
arrangement hereinafter described we force the oil in any direction and for a
considerable distance, thus obviating the necessity of a person getting in close
proximity to the working parts of machinery when in motion.
In carrying out our Invention according to one modification we place at the end
of the can nearest the spout a cylinder in which a plunger attached to a rod and
worked by a spiral or other spring, one end of which rod passes through the top of
the can at an angle or any other suitable position, the upward or return motion
of which is actuated by the spiral or other spring attached to the rod. On the end
of the plunger we fix a valve, which on its return motion fits in a seating formed
at the bottom of the cylinder or any other suitable position, thus preventing the oil
escaping when not desired.
According to another modification, instead of using the valve attached to the
bottom of the plunger we propose to use a sliding valve and disconnecting the pipe
beyond the cylinder. The sliding valve is worked by a cross lever or other suitable
levers; a slot is cut in the cylinder flush with the bottom of the can in order to
allow the oil to flow into the cylinder when the plunger is at the extremity of its
upward movement.
We also propose, by using other suitable appliances, to force the oil through the
orifice or spout of the can, say, for example, an air valve formed bellows shape or
otherwise.

EE
Our Invention has for its object improvements in oil feeders, which by an
arrangement herein after described we force the oil in any direction and for a
considerable distance, thus obviating the necessity of a person getting in close
proximity to the working parts of machinery when in motion. In carrying out our
Invention according to one modification we place at the end of the can nearest the
spout a cylinder in which a plunger is attached to a rod and worked by a spiral
spring, or other spring, one end of which rod passes through a stuffing box at the
top of the can at an angle or any other suitable position, the upward or return
motion of which is actuated by a spiral or other spring attached to the rod. On
the plunger we fix a valve, which on its return motion fits in a seating formed at
the bottom of the cylinder or any other suitable position, thus preventing the oil
from escaping when not desired. According to another modification, instead of
using the valve attached to the bottom of the plunger we propose to use a sliding
valve and disconnecting the pipe beyond the cylinder. The sliding valve is worked
by a cross lever or suitable levers. A slot is cut in the cylinder flush with the
bottom of the can in order to allow the oil to flow into the cylinder when the
plunger is at the extremity of its upward movement. We also propose, by using
other suitable appliances, to force the oil through the orifice or spout of the can, say,
for example, an air valve formed bellows shape or otherwise.
DESCRIPTION OF DRAWING.
The Drawing represents a longitudinal section of our oil feeder. In reference to
the Drawing the cylinder A is placed about two thirds of its length outside the can
at the spout end; the plunger B attached to the rod C is worked by pressing the
button D, thus causing the oil to be ejected into the chamber E, and so through the
spout. The valve F is secured to the rod and fits into a seating in the bottom of
the cylinder. By taking the pressure off the button the spring Ğ causes the return
motion of the plunger. The stuffing box E has for its object the prevention of the
escape of the oil. The oil enters the cylinder through the slot I, the slot being so
placed that the can if desired can be completely emptied of the oil.
