plate and two veneer bulkheads. Steel tube braces are runfrom points near lower longerons at station 3 to front end of engine bed, and also from station 2 to lower edge of engineplate. Two passengers are accommodated in the front seats,which are of mahogany-birch-mahogany veneer. Separate cushions are provided for the seats and backs. Safetybelt straps are carried down by means of a steel ribbon to one of the heavy longitudinal members near the lowerlongerons. The seats are of veneer. A continuous aluminium fire-proof wall separates the engine section from the front JUNE 17, 1920 the same construction as the larger magnetos, and is mountedin front of the pilot's instrument board. The engine is primed through the pet cocks on the intake manifolds andturned over compression on about three cylinders, by the airscrew. The mechanician stands aside and the pilot putsthe ignition switch on and turns the starting magneto by hand. A V-type landing chassis is fitted, the wheel tread being5 ft. 6 ins. Wheels, 26 ins. by 4 ins. Axle 1J in. diameter ; ^-in. wall. The axle is located 1 in. aft of the lower wingleading edge. Chassis members are of spruce 5.5 ins. by 1.5 in. streamline section. Upper ends are secured to body by means THE ORENCO TOURISTER : The dual side-by- side aileron and elevator controls cockpit. A locker located between top longerons and thecurved cowling will hold about 2-5 cubic feet of contents. The passengers' floor is of three-ply veneer resting directlyon the lower longerons. The veneer flooring is carried above the lower longerons by lightened transverse stringersstrengthened on the underside by longitudinal members, to which the rudder foot-bar pyramids are bolted. Windshields of transparent celluloid are built up withaluminium frames, the rear shield being designed so as to permit unrestricted vision over the sides in making landings. The mahogany instrument board is fitted with a tachometerindicating up to 2,000 r.p.m., a Taylor Instrument Company's THE ORENCO TOURISTER : The control leadsfrom rear cockpit. Elevator cables at side ; rudder cables, under seat of double forked plate fittings with longitudinal pins. Shockabsorber cord is attached to saddle fittings outside the chassis members, giving a maximum of impact absorptionclose to the wheels. Double cables, with spruce fillers between, brace the forwardchassis struts ; no cables aft. Two steel tubes space lower ends of chassis and a Balsawood streamline fairs in the spacing tubes. This streamline unit is 9 ins. by4 ft.; it has some of the properties of a wing,and does not add to the head resistance. Two control sticks and foot bars are provided in the rearcockpit. Control column and members are of square steel tube. The transverse shaft with sheet-steellevers for elevators is carried on bronze bear- ings at either side of the cockpit. The verticalcolumns have forked lower ends. A spacer bar is run between the columns about 8 ins.above the transverse shaft. Aileron cables terminate at spacer bar ends. Cables rundirect to guide pulleys which lead the cables THE ORENCO TOURISTER : The front seatarrangement, showing 27-gal. petrol tank, and dual rudder bars The Orenco Tourister: The petrol strainer under the floor of the rear cockpit altimeter with zero mark adjustable with sea level, andindicating up to 25,000 ft. ; 8-day Waltham watch ; oil gauge ; Boyce distance-type thermometer for engine watertemperature. All instruments have " radium " dials. A throttle control lever is provided at the centre of the instru-ment board so that it may be operated from either the right or left seat. The carburettor altitude adjustment lever isat the right longeron. For starting, a Dixie type 800 magneto is used. It is of through the transverse shaft bearings, from which point thecables emerge from the body. Cables run around pulleys at outer wing struts and then up to upper ailerons. A steel tube bar, streamlined with Balsa wood, connectsupper and lower ailerons. The compensating aileron cable runs from lower ailerons to a pulley at upper wing and thenacross the underside of upper wing. Turnbuckles for adjustment are provided at centre section. Fibre guides onwing struts prevent wear and whipping of cables. 646
