- "upright standards" - probably this refers to the vertical bars between the stacked wings, that is, the aeroplanes
- "a small angle of incidence" - that is forward and rear edges of the wing (airfoil or aeroplane) are at about the same level relative to the oncoming airflow ; an orientation in which the air flow is only minimally interrupted by the wing ; see en:w:Angle of incidence (aerodynamics)
- "equilibrium, or lateral balance of the apparatus" -- probably refers to the dangers of either sliding or rotating toward one side
- "a frame composed of two parallel transverse spars 3, extending from side to side of the machine"
- "their ends being connected by bows 4, extending from front to rear of the machine"
