Power by the Combined Action of the Vapour Generated' in
Slacking Lime and a Blast.
I THOMAS STOCKLEY Mason of 9 Park Street Southsea Portsmouth do hereby
declare the nature of the said invention for IMPROVEMENTS IN MACHINERY FOR
OBTAINING AND APPLYING MOTIVE POWER BY THE COMBINED ACTION OF THE
VAPOUR GENERATED IN SLACKING LIME AND A BLAST and in what manner the
same is to be performed to be particularly described and ascertained in and
by the following statement :-
The features of novelty in this invention consist in utilizing the vapour or steam
arising from lime whilst being slacked in a closed vessel or receiver in conjunction
with a blast produced by a fan or blower enclosed in a circular chest the combined
action of these forces operating on other parts of the machinery hereafter described
produceing a motive power capable of employment for various purposes such as
driving tram cars pumping and generally in actuating machinery.
Fig. 1 of the accompanying drawings is a side view in elevation of an apparatus
embodying my invention. Fig. 2. is a plan of the same. Fig. 3. is a view in
elevation of the levers H. T. and claw block T. circular slides P. G. or S. S. 2.
segments of circles N. O. in levers rolling motion: S. in segments in levers and
pendulum R. with sectional spindle S. passing through the bottom centre of the
circular slides P. G. or S. S. 2. and pendulum rod R. Fig. 4. is a side view of blast
chest M. blast or blade wheel K. fan V. F. 1. F. 2. F. 3. F. 4.
The apparatus consists of a cast or wrought iron frame of any suitable form and
dimensions supporting the various parts forming the machine whose construction
and action is as follows:-
At one end of the frame is a cylindrical or other shaped vessel or receiver of cast
or wrought iron A. in which a certain quantity of unslacked lime is placed. This
is slacked whilst in the receiver (which is hermetically closed) by the introduction
of a sufficient quantity of water the supply of which is maintained for keeping the
machine working by means of a tube B. comeing from a tank placed beneath the bed
of the frame or in any other convenient position. The water is injected in form
of a spray through a perforated nozzle C. on the pipe B. into the receiver A. (it

page_text: will be seen in elevation Fig. 1.) by means of the pump E. worked by the central
lever D. as previously mentioned the vapour or stean arising from the slacked lime
act upon a piston working in a cylinder F. mounted near the top of the receiver A.
Attached to the piston rod F. is a connecting rod G. the end of which rod is attached
to the lever H. which in its turn is connected to an equilateral three throw crank I.
whose axis turns in bearings in the centre of the frame or in any other suitable
position. On one end of the crank axis is a fly wheel J. keyed on the crank whilst
at the other end is fixed or keyed an eight or other bladed blast wheel K. enclosed
in a square chest M. as will be hereafter explained.
On this crank I. six levers are mounted one of which D. works the pump E. 1
another H. communicates motion from the piston rod F. and connecting rod G. to
the crank I. whilst all alike actuate two segments of a circle N. O. which are cut or
cast in the levers H. D. and all the other levers.
These segments are intended to induce the reciprocating and rocking motion of
the circular slides P. G. or S. S. 2 by aid of the pins S. and S. S. 2. in cach of the
segments, Fig. 3. showing the segments and circular. slides levers claw block pins
and pendulum on an enlarged scale.
Each of the pendulum rods is suspended to a spindle S. passing through the
bottom centre of the circular slides P. G. or S. S. 2 and pendulum rod R. The axes
of these spindles are borne and oscillate on or in brasses or other bearings mounted
on cross bars on the top of the frame Fig. 2. at each end where they form three
divisions.

These pendulums in their alternate to and fro motion assist to work the three
throw crank I and also regulate its movements by raiseing..or lowering the
pendulum bobs.
This crank I communicates motion to the eight bladed blast wheel K. keyed to
the crank I as allready described and contained in the blast chest M.
At one end of the machine is a drum F. 2 supported and turning in bearings
borne by supports or a frame fixed to the ground or on a stone or any suitable
place. Motion is imparted to this drum by an endless band or strap passing over
a pully F. 1 which is keyed to the same spindle as F. 2. to F. 4. and an endless
band or strap from F. 2. to F. 3. being the pully of the fan V. situated close to the
blast chest M. causes this fan to revolve and the blast or draught produced acting
on the blades of the blast wheel K. gives it an additional force. The blast or
draught after striking the blades of the blast wheel escapes through an aperture
made in the end of the chest and can be utilized for blowing a whistle or for
ventilation or any other purpose.
The receiver is fed with lime through an aperture near the top of the receiver A
Top aperture is W. A. bottom aperture is X. A. serves to withdraw the lime when
no longer useful in generating vapour. Both these openings are hermetically closed
by doors screwed firmly over the apertures. The lime withdrawn is in a condition
for use in the manufacture of cement, morter, and so forth and can be sold for
such purposes and for more money than it cost in the first place being ready for
any use.
It should be observed that in case of the employment of the machine for driving
tram cars the fan is only sufficing to drive the blast wheel in one direction or say
up the line it must be supplemented by a second fan placed above the first which
acting on the blades of the upper part of the wheel causes it to revolve in a contrary
direction or say down the line this is simply effected by slipping the band from the
lower fan to the upper one..
Attached to one of the throws of the crank is a spiral spring the other end of
which is made fast to one of the cross bars of the frame or may be placed in any other
position. The crank in its revolveing causes the spring to alternately expand and
contract which facilitates the oscillation of the pendulums.
When it is desired to stop the machine a break of any convenient discription is
applied either to the fly wheel or to the crauk axes.

page_text: Haveing now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
1st The method of obtaining motive power by slacking of lime in a closed
vessel A. and utilizing the vapour arising therefrom to actuate a piston contained
in a cylinder F. the rod of which piston is attached to the connecting rod G. which
is attached to the lever H. driving a three throw equilateral crank I.
2nd Joint lever T. and claw block T. on throw of crank.
3rd The pendulums R. by aid of the circular slides P. G. or S. S. 2. and segments
of circle N. O. and rolling motion S. which works in the segments in the levers the
sectional spindles S. S. which goes through the bottom centre of the circular slides
and pendulum rods R.
4th The method of communicating motion to the blast wheel K. and fan V. by
means of belts as and for the purpose herein specified.
5th The blast chest M. with apertures and blast wheel K. which is in the blast
chest M.
