I, WILLIAM WILKINSON, of Holme House Foundry, Wigan, in the County of
Lancaster, Engineer, do hereby declare the nature of my invention for "IMPROVE-
MENTS IN. SURFACE AIR CONDENSERS FOR TRACTION ENGINES FOR TRAM OR OTHER
ROADS," to be as follows:-
:
My invention relates to surface air condensers applicable, to traction engines for
tram or other roads, and it is designed to effect the usual object of such device in a
more effective and convenient mauner than hitherto.
My invention is of the following nature:-
Forming the roof of engine cover, or fixed in any other more convenient
position on the engine, I place a tank or casing with thin metal tubes running
transversely through it from side to side, or longitudinally from end to end hori-
zontally, the steam to be condensed being led into said casing surrounding the
tubes, and the air for cooling flowing through the tubes in the same manner as the
water in marine surface condensers.
My invention applies more particularly to the following device, viz:
"
To induce a current of air to flow through the tubes by the action of the wind,
or in case there is no wind, by the motion of the condenser through the still air, I
fix opposite each vertical row of tubes a metal screen, hereafter called a "venetian,'
pivotted on centres and so placed as to be capable of being turned to any suitable
angle relative to the axis of the tubes, and to be reversible at will.
To obtain simultaneous movement in reversing the angle of them, I fix a lever on
the axis or pivot of each " venetian" and couple them together with a rod to be
actuated from any convenient position on the engine, and I also connect the
"venetians" fixed at one end of the tubes, to those fixed at the opposite ends, by
means of suitable coupling rods and levers, so that when one set is being reversed,
the others are necessarily undergoing the same operation at the same time.
Inside the casing or tank I fix cross diaphragms or baffle plates, so as to more
evenly distribute the steam amongst the cooling tubes for condensation.
To counteract the unequal contraction and expansion of the tubes, I bend each
one into a reverse curve in a similar manner as the boiler tubes embodied in my
patents N° 1773 of 1884 and 5560 of 1883.

I, WILLIAM WILKINSON, of Holme House Foundry, Wigan, 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:-
My invention relates to surface air condensers applicable to traction engines for
tram or other roads, and it is designed to effect the usual object of such devices in a
more effective and convenient manner than hitherto.
Forming the roof of the engine cover, or fixed in any other more convenient
position on the engine, I place a tank or casing, with thin metal tubes running
transversely through it from side to side, or longitudinally from end to end horizon-
tally, the steam to be condensed boing led into or through the said casing
surrounding the tubes, the air for cooling flowing through the tubes in the same
manner as the water in marine surface condensers.
In order that my invention may be the better. understood, I now proceed to
describe the same in relation to the drawings hereunto aunexed, reference being had
to the letters and figures marked thereon.
Like letters refer to like parts throughout the drawings.
Figure 1 shows my condenser in elevation with "screens" partly broken away.
Figure 2 shows the same in plan.
Figure 3 shows detail of relief and inlet air valves hereafter mentioned.
To induce the current of air to flow through the tubes A by the action of the
wind, or in case there is no wind, by the motion of the condenser through the still
air, I fix opposite each vertical row of tubes a metal screen B, hereinafter called a
'venetian," pivotted on centres, and so placed as to be capable of being turned to
any suitable angle relative to the axis of the tubes, and to be reversible at will.
И
To attain simultaneous movement in reversing the angle of them, I fix a lever C
on the axis of the pivot of each venetian, and couple them together with a rod D,
to be actuated from any convenient position on the engine, and I also connect the
"venetians" fixed at one end of the tubes to those fixed at the opposite ends by
means of suitable coupling rods and levers E, so that when one set is being reversed,
the others are necessarily undergoing the same operation at the same time. Inside
the casing or tank I may fix cross diaphragms or baffle plates, so as to more evenly
distribute the steam amongst the cooling tubes for condensation.
To counteract the unequal contraction and expansion of the tubes, I bend each
one into a reverse curve in a similar manner to the boiler tubes embodied in my
patents No 1773 of 1884 and N° 5560 of 1883.
For the more efficient working of my device, and in any convenient position on
the top of the condenser I fit a relief valve F and an air inlet valve G.

page_text: Having 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 construction of surface air condensers consisting of a series of tubes
passing through a steam tank and having at their mouths a series of shutters or
venetians to induce a draught of air therethrough coupled together and operated
by a lever, substantially as and for the purposes specified.
2nd The combination with such a condenser of any suitable relief and air inlet
valves, substantially as and for the purposes specified.
