Miscellaneous Implements E.rhilnted at Newcastle , 1908. 185 
It was exhibited for the first time last year at Lincoln, 
and then attracted the attention of the Judges, who recom- 
mended that it should be put forward as a new Implement for 
this year. The system and working parts are fully described 
and illustrated in last year’s (1907) Journal of the Society, 
pp. 185 to 137. 
The improvements made since last year are of an important 
nature, and consist of : — 
(а) A new condenser arrangement which is best described 
as an air vessel on the main suction pipe encased in a cast iron 
vessel which forms the actual condenser. The arrangement 
enables the pump to prime itself on starting, and to work more 
efficiently on a long suction, at the same time it does away 
with some joints in the structure which might have given 
trouble, and which at any rate were somewhat hard to get at. 
(б) A simple method of making the water cushion at the 
bottom of the pump certain and satisfactory in action has been 
introduced. 
( c ) The gland of the pump rod has been improved, and the 
machine as now made is put together in a much more compact 
form, with the result that the joints have been largely reduced 
in number and simplified in form, and the cross copper pipe 
connections done away with. 
(d) The present boiler is made so that it can be easily taken 
to pieces for cleaning purposes, and the apparatus for feeding 
it with water has been made stronger and simpler, there being 
no float, spring, or screw employed in its working parts but 
only a weighted valve and counterpoise. 
In its present form it should prove to be a very useful pump 
for domestic supplies, as it requires a minimum of attention. 
In order to show clearly the capabilities of the machine, 
the following figures, which are reported to have been actually 
obtained in working, may be of value : — A boiler weighing 
20 lbs. heated by a lamp burning ordinary paraffin oil, has 
driven one of these engines continuously at 100 strokes per 
minute, raising 350 gallons of water an hour, from 20 ft. 
below ground to a height of 40 ft. above ground level, the 
pressure in the boiler remaining at 0 with a consumption 
of paraffin of 1 pint per hour, which, with paraffin at 8<7. per 
gallon, works out at 1 d. per hour. 
These machines are automatic, and therefore when once 
started require no attendant. They can be started and looked 
after by farm labourers without fear of accident to themselves 
or the machine.
