LOCOMOTIVE STEAM-ENGf
The paper read at the last meeting of the Institute
Civil Engineers was by Mr. J. G. I3odiner, M. In3t• sore
" On the advantages of working engines with high-Pre.s
steamd
expansively and at great velocities." The author Der of
his observations upon the principle of a cousiderable rve
piston being essential for taking advantage of the init.'ides
impulse of highly elastic steam, in contradistinction to the
of its percussive action, which had some time ago found s""il,
cates. In order, therefore, to take advantage of this tloaction,
and be enabled to cut off the steam at an early period et

stroke, the piston, at short intervals, and consequently leer
a great number of strokes within a given time, must trave,
cow
a limited distance, that as little as possible of le heat, WO
sequently of the elastic it, should be ost.
It has been generally acyknowledgedl that the action of a s_bi°r4ft
crank and rapid stroke is very disadvantageous to the ffs":.os,
and foundations of ordinary engines. Alr. Bodmer has, Ine'tioo
strutting his compensating engines, concentrated the„
and confined the strain to the crank, connecting rod, an" P the
rod. By this circumstance, he has bees enabled to collo

reduction of the actual weight of the machinery an" "..„,per
coals on board steam-vessels on long voyages. The rrio.
considered at great length the reasonings upon these rt, of
ciples, and in tabular forms gave the comparative re'''. of
this and the ordinary engines. The peculiar construction
the compensating engines was illustrated by several Weser
and detailed drawings, showing the peculiar action a the ,che

the P
great difficulty encountered appeared to have been in the Toy
of the air pump, which were destroyed by the extreme
of the action ; this was provided for by constructing !
eir
pump without valves. By a peculiar arrangement of tzr the
and water passages, it became practicable to substitute I
ordinary cover a piston travelling through a very limited srfep
and for the air-pump bucket a solid piston travelling tb, tbc sod
length of stroke. The valves were thus done away In ',tie!!
the action of the engine became complete. This coast° end
has been adopted with great success on several stational or
locomotive engines, and is now being applied to suarittisr
gines, to which it is peculiarly applicable, as it is of gr W Pe-
portance to be enabled to work the Archimedian scre
peller without the insertion of bands or wheel-works. sir

circumstances of the load of the engine, Mr. Siele„°o- esl
