Abstract
Abstract A motor mount for use in model airplanes is disclosed. The motor mount includes a mounting plate and a pair of spaced arms extending generally perpendicularly from the mounting plate. Each arm includes a generally horizontal surface for supporting flanges of a motor or engine and an angled surface spaced above and sloping toward the horizontal surface. A clamping plate is secured to each of the angled surfaces. Each clamping plate secures a flange of the motor to one of said horizontal surfaces. The clamping plates can be secured to one of a plurality of locations along the longitudinal dimension of each arm.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
107 words
A motor mount comprising: a pair of arms extending outwardly from a mounting plate; said arms extending in their lengthwise dimension generally perpendicularly from said mounting plate; said arms being spaced from one another to form a slot for receiving a motor; each arm having a generally horizontal surface for contacting flanges of a motor to be mounted thereon and an angled surface spaced above and sloping toward said horizontal surface; and clamping means mounted on said angled surfaces and adapted for contacting upper surfaces of the flanges of the motor and for securing the flanges of the motor between said clamping means and said horizontal surfaces.
Claim 2
Dependent Claim
107 words
A motor mount comprising: a pair of arms extending outwardly from a mounting plate; said arms extending in their lengthwise dimension generally perpendicularly from said mounting plate; said arms being spaced from one another to form a slot for receiving a motor; each arm having a generally horizontal surface for contacting flanges of a motor to be mounted thereon and an angled surface spaced above and sloping toward said horizontal surface; and clamping means mounted on said angled surfaces and adapted for contacting upper surfaces of the flanges of the motor and for securing the flanges of the motor between said clamping means and said horizontal surfaces.
