PROVISIONAL SPECIFICATION.
Improvements in Air-compressing Engines, and other similar
Engines.
I, JAMES TAYLOR, of 93 Victoria Street, Newton, Hyde, near Manchester,
Engineer, do hereby declare the nature of this invention to be as follows:-
My first improvement relates to the link motion which forms a combined cross
head and slide block. The link is fitted with a block which is tapered externally
to fit in the link, and also internally to fit on the crank pin, which latter is hollow,
and is provided with a spring that draws the block up on the crank pin as it wears,
thus making the bearing self-adjusting.
My second improvement relates to the air compressor, and consists in dispensing
with the ordinary suction valves by giving the air pump or compressor a horizontal
travel to and fro on the bed plate, so as to allow the air to rush in at each end.
The covers or castings of such pump or air compressor are screwed down or
A slow
otherwise rigidly fastened to the bed plate and steam cylinder cover.
rotatory motion is given to the pump by means of a ratchet wheel worked from the
eccentric, so that the pump is always varying its position and lubricating the
piston.
My third improvement consists in placing suitable delivery valves in the piston.
Such valves are single and are operated alternately by suitable springs, thus
allowing the air to pass into the piston, the air being delivered through or down
the piston rod which is hollow.
My fourth improvement consists in packing the piston rods and rams on each
side whereby I dispense with one packing box, and press the packing tightly to
the rod as required, while the air compressor and steam cylinder are brought close
together.
Improvements in Air-compressing Engines, and other similar
Engines.
I JAMES TAYLOR of 93 Victoria Street, Newton, Hyde, in the County of
Chester, 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 improvements relate to air compressing engines and other similar engines
and the same will be readily understood on reference to the accompanying
drawings

page_text: Fig. 1 is a side elevation of an air compressing apparatus made with all my
improvements applied thereto.
Fig. 2 is an enlarged view of the crank pin and block and
Fig. 3 is a longitudinal section through the bollow piston rod and piston
hereafter described.
My first improvement relates to the construction of the link motion in which the
link a answers as a cross-head and slide block, for connecting the crank pin directly
to the piston. I form a slot in the link or cross head a at an angle between
45 and 90 degrees and not at right angles with the centre line of the piston and
thus I obtain an increase of motion of the said piston in proportion to the throw of
the crank a+, and I decrease the wear and tear against the pedestals or bearings
of the shaft a++.
The link a is fitted with a block 6 made very slightly tapered outside to the fit
in the link a and tapered inside to fit on a correspondingly tapered crank pin c.
This crank pin is hollow, and provided with a spring c (see Fig. 2) which draws
the block up on the crank pin e as it wears, which makes this bearing self-
adjusting.
Or other means may be provided for adjusting the block upon the crank pin
either automatically or by hand.
My second improvement relates to air compressors, dispensing with the ordinary
suction valves; and consists in giving the cylinder d or the air pump or compressor
a longitudinal travel to and fro ou the bed plate so as to allow the air to rush in at
each end, the covers or castings dd of each pump or air compressor being screwed
down, or otherwise rigidly fastened respectively to the bed plate and the steam
cylinder cover y.
The cylinder d is free to move between the two end plates d' d for a short
distance (say or inch) and thus the motion of the said cylinder is obtained by
the action of the atmosphere as the piston starts to move in either direction.
The two end plates d' d² are so fitted or formed or faced as to make an air tight
joint with the opening in the end of the cylinder when the latter comes in contact
with one or the other of the said plates d' or d². I also prefer to fix form or
provide a circular plate, boss, or disc ft of suitable thickness and diameter at each
side of the piston to fill up the opening in one of the cylinder ends as the piston f
reaches the corresponding end of its stroke.
This pump cylinder d has also, or may have, a slow revolving motion given to it
by a ratchet wheel e which may be worked from the eccentric so that it is always
changing its position and lubricating the piston f.
My third improvement consists in placing the delivery valves flf" in the
piston, which is hollow, and communicates with a hollow or tubular piston rod h.
The valves" are single, and work alternately being provided with springs g
which allow the air to pass into the piston the air being delivered through or down
the trunk or hollow piston rod h.
My fourth improvement relates to the packing of the piston rods h¹ or rams
and consists in packing the same on each side as seen at z on Fig. 1 on which the
packing plate and packing are not shown and by this means I press the packing to
the rod as required; and I bring the air compressor d and steam cylinder y very
Dear together as shewn at the same time dispensing with one packing box. Fig. 1
is a section of the stuffing box at the line A B on Fig. 1. z is the box, z¹ z' are
the covers or packing plates and 23 the packing held in place by the said plates 2¹.
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 :-
:-
1. A link or cross head connecting the crank pin direct to the piston having the
slot at an angle with the motion of the piston substantially as herein before
described and illustrated by the drawings annexed.
2. A link fitted with a block which is made tapered outside to fit in the link and

page_text: tapered inside to fit on the crank pin and provided with means for drawing the
block up on the crank pin as it wears, substantially as hereinbefore described and
illustrated by the annexed drawings.
3. In an air compressing engine or pump giving the cylinder of the air
compressor or pump a to and fro motion lengthwise on the bed plate between
two fixed covers or ends, either in combination with, or without, a slo y revolving
motion, substantially as herein before described and illustrated by the annexed
drawings.
4. A hollow piston rod and hollow piston, the said piston being provided with a
valve or valves at both sides thereof working alternately to deliver the air through
the piston and piston rod, substantially as herein before described and illustrated.
5. The method of packing the piston rods or rams from the sides and bringing
the compressor and steam cylinder close together, thus dispensing with one packing
box, substantially as hereinbefore described and illustrated by the drawings
annexed.
