LOUIS COATALEN, WOLVERHAMPTON, ENGLAND, ASSIGNOR OF ONE-HALF TO SUNBEAM MOTOR CAR COMPANY LIMITED, 0]? WOLVERI-IAMPTON, ENGLAND.
INTERNAL-COMBUSTION ENGINE FOR AEROPLANES.
Application filed October 24, 1916.
To all about it may concern:
Be it known that I, Lonls COATALEN, a subject of the King of Great Britain, and resident of IVolverhampton, in the county of Stafford, England, have invented certain new and useful Improvements in Internal- Combustion Engines for Aeroplanes, of which the followmg is a specification.
On most aeroplanes the engine is inclosed in the fuselage and the exhaust gases discharge through pipes leading outside the In the case of engines having two or more rows of cylinders with the exhaust pipes leading upward between the cylinders the construction of the fuse lage cowling is somewhat difficult owing to the presence of these pipes and the arrangement at present adopted tends to box in a great part of the hot exhaust pipes.
The present invention has for its object to overcome these defects by the use of a special shield and to render the fitting of the engine to the aeroplane a simple matter.
In the accompanying drawings,
Figure 1 is a perspective view of part of an aeroplane to the engine of which this invention is applied.
Fig. 2 .is a fragmentary front view showing the shield in position, together with part of the aeroplane and the adjacent cowling.
Like letters indicate like parts throughout the drawings.
It is customary to locate the engine within a cowling which forms part of the fuselage of the aeroplane but it is objectionable to include the exhaust pipes within the cowling. With V-type multicylinder engines if the individual exhaust pipes pass through holes in the cowling the erection of the engine on the machine is complicated.
To overcome this, according to this invention, there is attached, more or less permanently, to the engine a shield A which in cross section is trough shaped and this is conveniently attached to the studs B which secure the exhaust pipes C to the cylinders .D. In the case illustrated the exhaust communicate with a pair of ex- Gopies o,

pansion chambers E and these extend along the trough shaped shield and communicate with vertical pipes of any suitable kind. The cowling is indicated at F and if desired the shield may be shaped so as to join up at the points G with the cowling or it may be terminated at the points H, in which case the cowling extends down to the same points. In either case when the engine is being fitted to the aeroplane it is a simple matter to build the cowling up to the edges of the shield, and the aeroplane builder can practically ignore the presence of the exhaust pipes.
At the rear the bottom of the trough may curve upward to the level of the cowling, as is shown at J.
By this means the exhaust pipes are cooled and the fitting of the engine to the aeroplane facilitated and the engine and its exhaust pipes do not require to be interfered with by the aeroplane builder.
What I claim as my invention, and desire to secure by Letters Patent, is
1. In an aeroplane, the combination of an internal combustion engine having rows of cylinders, a trough shaped shield between said rows and attached to said cylinders, exhaust pipes within said trough shaped shield, and a fuselage cowling joined to the edges of said shield, substantially as set forth.
2. In an aeroplane, the combination of an engine having rows of cylinders, a trough shaped shield between said cylinders, exhaust pipes within said trough shaped shield, attachments securing said exhaust 85 pipes and said shield to said cylinders, and a fuselage cowling joined to the edges of said shield, substantially as set forth.
In testimony whereof I have signed my name to this specification in the presence of 90 two subscribing witnesses.
