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.
Claim 3
Dependent Claim 24 words
A motor mount in accordance with claim 1 wherein said arms and said mounting plate are integrally formed from a single piece of material.
Claim 4
Dependent Claim 35 words
A motor mount in accordance with claim 2 wherein said mounting plate has a centrally disposed hole therethrough and a plurality of smaller holes for receiving means for securing the motor mount to a surface.
Claim 5
Dependent Claim 19 words
A motor mount in accordance with claim 2 wherein said single piece of material is made of cast aluminum.
Claim 6
Dependent Claim 17 words
A motor mount in accordance with claim 1 wherein said arms extend generally parallel to one another.
Claim 7
Dependent Claim 30 words
A motor mount in accordance with claim 1 including a means for securing said clamping means to one of a plurality of locations along the lengthwise dimension of each arm.
Claim 8
Dependent Claim 34 words
A motor mount in accordance with claim 6 wherein said clamping means includes a plate member and said securing means includes a plurality of threaded holes through each arm adapted to receive fastening screws.
Claim 9
Dependent Claim 152 words
A motor mount for mounting a motor to a model airplane comprising: a mounting plate having a centrally disposed hole for reducing the weight of the motor mount and a plurality of smaller holes for receiving means for fastening the motor mount to a model airplane; a pair of spaced arms formed integrally with said mounting plate from a single piece of material and extending generally parallel to one another; each arm having a generally horizontal support surface for supporting a flange of the motor and an angled surface spaced above and sloping toward said horizontal surface; a clamping plate removably secured to each angled surface for clamping flanges of the motor between said plates and said horizontal surfaces; and each arm having a plurality of threaded holes extending into said angled surface for securing said clamping plates to one of a plurality of positions along the longitudinal dimension of each arm.
Claim 10
Dependent Claim 152 words
A motor mount for mounting a motor to a model airplane comprising: a mounting plate having a centrally disposed hole for reducing the weight of the motor mount and a plurality of smaller holes for receiving means for fastening the motor mount to a model airplane; a pair of spaced arms formed integrally with said mounting plate from a single piece of material and extending generally parallel to one another; each arm having a generally horizontal support surface for supporting a flange of the motor and an angled surface spaced above and sloping toward said horizontal surface; a clamping plate removably secured to each angled surface for clamping flanges of the motor between said plates and said horizontal surfaces; and each arm having a plurality of threaded holes extending into said angled surface for securing said clamping plates to one of a plurality of positions along the longitudinal dimension of each arm.
Claim 11
Dependent Claim 19 words
A motor mount in accordance with claim 8 wherein said single piece of material is comprised of cast aluminum.
Claim 12
Dependent Claim 26 words
A motor mount in accordance with claim 8 wherein the cross sectional area of each arm decreases in a direction extending away from said mounting plate.
Claim 13
Dependent Claim 153 words
A motor mount for mounting a motor to a model airplane comprising: a mounting plate having a centrally disposed hole for reducing the weight of the motor mount and a plurality of smaller holes for receiving means for fastening the motor mount to a model airplane; a pair of spaced arms formed integrally with said mounting plate from a single piece of material and extending generally parallel to one another; each arm having a generally horizontal support surface for supporting a flange of the motor; and each arm having an angled surface spaced above and sloping toward said horizontal surface; and means for securing said flanges of various sized motors to said arms, said securing means being mounted to said angled surfaces, said securing means allowing various thickness of flanges to be secured to said arms and permitting the position of said flanges to be adjusted toward and away from said mounting plate.
Claim 14
Dependent Claim 153 words
A motor mount for mounting a motor to a model airplane comprising: a mounting plate having a centrally disposed hole for reducing the weight of the motor mount and a plurality of smaller holes for receiving means for fastening the motor mount to a model airplane; a pair of spaced arms formed integrally with said mounting plate from a single piece of material and extending generally parallel to one another; each arm having a generally horizontal support surface for supporting a flange of the motor; and each arm having an angled surface spaced above and sloping toward said horizontal surface; and means for securing said flanges of various sized motors to said arms, said securing means being mounted to said angled surfaces, said securing means allowing various thickness of flanges to be secured to said arms and permitting the position of said flanges to be adjusted toward and away from said mounting plate.
