O.V.S. Bulleid (53-5) was highly critical of he use of a mercury U-tube
for measuring smokebox vacuum and advocated the Cambridge Instrument developed
with Gresley. Described his WW2 experiment of fitting a locomotive with two
separate chimneys in an attempt to break-up the exhaust trail. He advocated
larger chimneys with a 7 to 1 ratio rather than the more usual 3 to 1 ratio.
and cited work on Lord Nelson class chimneys H.I. Andrews (55-6) commented
upon smokebox efficiency and its measurement; E.S. Cox (56-9) thought that
chimneys might "certainly be made larger than at present" and noted that
the Duchess Pacific with double chimneys were working at nearly the Author's
suggested criteria. He also described the evolution of tube sizes in the
Jubilee class boilers which attained 1 7/8 inch ith a double chimney; W.F.
McDermid (59) noted that Great Eastern locomotives working on Brentwood bank
with a full regulator had a clear exhaust when notched up and Sanford noted
that the thickness of the fire was essential for good steaming; E.C. Poultney
(59-60); T. Henry Turner (60); H. Holcroft (61-2) asked why quite small leaks
into the smokebox had such a major influence on steaming and Sanford in reply
could give no sound reason; W.F. McDermid (62) noted his own papers in Journals
No. 108 and 112 (1932/3); W.H. Hutchinson (62-3) commented upon the very
small chimneys fitted to some GWR locomotives, notably the 43XX class - Holcroft
replied that these were designed using the Goss formula; Hutchinson also
refered to the square Belgian chimneys which E.W. Selby noted were square
inside and Sanford noted that such chimneys were sound as there was a great
surface area for a given cross-section. Presented at Derby on 31 January
1945 with E.S. Cox as Chairman (remarks 69-71); T. Baldwin (71); J.W. Caldwell
(71-2) noted the power loss in exhaust due to back pressure;
G.F. Horne (72) noted that the US 2-8-0s combined
good smokebox vacuum with soft exhaust; E. Durnford noted Chapelon's use
of large steam passages; E. Sharp (73) observed that smokebox vacuum varied
with different rates of working; D.W. Peacock (74)

H. Holcroft spoke on behalf of O.V.S. Bulleid (365-8) on the Southern
Railway electric locomotives. E.S. Cox (369-72) spoke about Bissel trucks
and Cartazzi axleboxes. J.E. Spears (372). W.O. Skeat argued that symetrical
tank engines (2-6-2 and 4-6-4) did not ride as well as unsymetrical types,
such as 2-6-4T.
