PROVISIONAL SPECIFICATION.
An Improved Motion and Means of Driving Compressors for Gas
and the like.
JOHN BAKER, Ice Factory, Fazely Street, Birmingham, Engineer, do hereby
declare the nature of this invention to be as follows:-
This invention relates to an improvement in compressors, by which the piston of
compressor makes four (4) strokes to each revolution of the engine. The com-
pressor being placed above or below, (as convenient,) the crosshead & connected
therewith by suitable rods as shewn on drawing.
A B & C shew the crank in three positions. A I BI & C1 shewing the improved
motion, giving one complete stroke to compressor for (2) half stroke of engine.

An Improved Motion and Means of Driving Compressors for Gas
and the like.
I, JOHN BAKER, A.MIME, of the Ice Factory, Fazely Street, Birmingham,
in the County of Warwick, Refrigerating Engineer, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be particu-
larly described and ascertained in and by the following statement:—
My invention has for its object an improved means of driving air compressors
and relates to the compression of gases and the like whereby the great strain on
the crank pin which takes place at each stroke on all compressors as at present
made is obviated by my improvement the foice of compression in the case of my
arrangement being divided up into several small concussions instead of one large
blow for each evolution of the engine or motor which is used for driving the
compressor while at the same time the reduced amount of concussion instead of
being received by the crank pin is transferred to a more substantial bearing.
In order that my invention may be clearly understood and more easily carried
into effect I have appended hereunto a sheet of drawings upon which I have fully
illustrated the nature of my said improvements
Figure 1 is a sectional elevation of a compressor driving cylinder and wheel
with my improved arrangement attached thereto
In carrying my invention into effect I arrange the compressor A with its stroke
at right angles to that of the stroke of the driving cylinder B and at the same time
place it intermediately between the said cylinder B and the fly wheel C, although
I do no confine myself to this particular position of the fly wheel. The one end d
•

page_text: of the motor piston d is preferably connected to the slide D which slides upon the
bed and the slide is connected by link F to the levers Il and H which in turn
are respectively connected the one to the compressor piston a' and the other to
the adjustable buffer K thus forming a toggle arrangement the centre h³ of which
on the forward stroke of the motor piston d passes the dead centre of the com-
pressor and occupies the position shewn by dotted lines h3 thus giving in its
stroke one working and one return stroke of the compressor piston a¹ the same
action occuring again on the return stroke of the motor piston d. By the con-
nection of the lever H' to the abutment K the whole of the concussion of the work
of the compressor instead of being received by the crank pin is transferred to the
bed E through the rods N at which point a buffer or cushion such as the spring M
is provided to receive it and thereby still further reduce the concussion while by
means of the rods N the most complete adjustment of the stroke of the compressor
piston a¹ can be effected by which absolutely no clearance is provided the piston in
such case touching the cover and thereby delivering all its contents, all danger of
breakage being obviated by the cushion M which accomodates any extraordinary
pressure.
The fly wheel C is connected to the cross head d by the rod R and crank S, and
the whole of the compressor and motor parts may be so raised if desired so as to
bring the adjustable buffer arrangement level with the bed.
Having now particularly described and ascertained the nature of my invention,
and in what manner the same is to be performed, I declare that what I claim
is:-
1st. In driving air or other compressors the toggle lever I and H¹ in combina-
tion with the motor cylinder B and adjustable buffer substantially as and for
the purpose herein set forth and illustrated upon the accompanying drawings.
2nd In driving air or other compressors the combination of the motor
cylinder B slide D toggle H H compressor A and fly wheel C substantially as
and for the purpose herein set forth and illustrated.
