PROVISIONAL SPECIFICATION.
A New or Improved Air-compressor or Blower.
I, WILLIAM TATTERSALL, of 8, Southfield Square, Bradford, in the County of
York, Engineer, do hereby declare the nature of this invention to be as follows:-
This invention relates to a new or improved air-compressor or blower and its
object is to provide an apparatus of simple construction adapted to supply com-
pressed air at an approximately uniform pressure.
The said improvements consist in the arrangements hereinafter described in
which a vibrating compressor-blade or vane is employed enclosed within a
vee shaped case provided with suitable valves and operated in any convenient
manner.
For this purpose I pivot a blade or vane in the narrow end of a vee shaped case
and the free end of such blade fits against the opposite end of said case which is
formed to a curve struck from the centre of the blade pivot. The inclined sides of
such case approximately meet at the narrow end and the parallel sides are the same
distance apart as the width of said blade. A feed or admission valve of suitable
construction is provided at each side of the blade or vane and also an emission valve
leading from each side into a receiver.
I may vibrate said blade or vane by means of an arm fixed upon the pivot of such
blade projecting through the case and operated by a crank or eccentric or in any
convenient manner.
As the said blade or vane is vibrated the air on both sides is alternately com-
pressed and forced through the emission valves into the receiver and the feed valves
alternately supply fresh air to each side of the blade or vane as the air at the
opposite side is being compressed.

COMPLETE SPECIFICATION.
A New or Improved Air-compressor or Blower.
I, WILLIAM TATTERSALL, of Arden Terrace, Plantation Street, Accrington, in
the County of Lancaster, 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:-
This invention relates to a new or improved air-compressor or blower and its
object is to provide an apparatus of simple construction adapted to supply compressed
air at an approximately uniform pressure.
The said improvements consist in the arrangements hereinafter described in
which a vibrating compressor-blade or vane operated in any convenient manner
is employed enclosed within a vee shaped case provided with suitable valves and a
receiver.
For this purpose I pivot a blade or vane in the narrow end of a vee shaped case

page_text: and the free end of such blade fits against the opposite end of said case which is
formed to a curve struck from the centre of the blade pivot. The inclined sides of
such case approximately meet at the narrow end and the parallel sides are the same
distance apart as the width of said blade. A feed or admission valve of suitable
construction is provided at each side of the blade or vane and also an emission valve
leading from each side into a receiver.
In the accompanying drawing
Figure 1, represents a sectional elevation of my improved blower.
Figure 2, is an outer view of the same.
Figure 3, is an end elevation of the blower, and
Figure 4, is a similar view of the other end.
The vibrating blade A is pivoted in the narrow end of the inner case B by the
journals a and a mounted in the bearings e and e¹ formed in the sides B1 and B2 of
the case. The journals a and a¹ project through each side of the case and are fitted
with arms C and C¹ connected by their lower ends by means of the connecting
rods d and d to the pins and of the crank dises D and D' mounted upon the
driving shaft E. The shaft E revolves in the bearings m and m² formed in con-
tinuations of the sides B1 and B2 and is provided with a driving pulley F. A
receiver His formed over the case B having a discharge passage G and india rubber
Hap valves J and J are fitted over the emission passages K connecting the inner
case with the receiver. Admission valves O and O¹ of similar construction but
opening inwards cover the admission passages L communicate with the outer
atmosphere.
In operation the blade A is vibrated from side to side of the vee case by means of
the arms C and C. During each vibration or stroke the air on one side of the blade
is forced through the emission passage on that side into the receiver the admission
valve being closed by the pressure, at the same time the other admission valve admits
air on the other side of the blade to replace the air forced through the other emission
valve during the previous vibration.
It will be understood that the blade A is made to closely fit the interior of the
case B and that the bottom of said case is formed to a curve struck from the centre
of the blade journals.
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 I am aware of
the Specification of Letters Patent No. 10759 of 1884 granted to James Campbell
Baker, and that I lay no claim to anything described and claimed in that Specifica-
tion, but what I claim is:-
An air compressor or blower constructed with a vibrating blade within a vee
shaped chamber communicating with a receiver, substantially as herein shown and
described and illustrated in the accompanying drawings.
