Abstract
Abstract The disclosure relates to a target assembly of the type for use in a target practice range. The target assembly includes a base, a motor in the base, a first rotatable member coupled to the motor, a second rotatable member and a pivotable target member coupled to the second rotatable member. The first rotatable member includes an extension which engages a radial slot within the second member during rotation to cause the second rotatable member to rotate for raising and lowering the target member. The first and second rotatable members have cooperating cam surfaces for locking the target member in a vertical and horizontal position and for freeing the rotatable members for rotation during the raising and lowering of the target member.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
196 words
A target assembly for use in a target practice range comprising: a carriage base; a motor mounted in said base including a driven shaft, said motor being capable of driving said driven shaft in first and second angular directions; a first rotatable member connected in driven relation with said driven shaft including a first axis of rotation and an extension extending parallel to and radially spaced from said first axis, said extension being arcuately displaceable between a first position and a second position about said first axis with rotation of said rotatable member; a second rotatable member having a second axis of rotation and including a generally radial slot extending from the periphery of said second member towards said second axis and dimensioned for receiving said extension of said first rotatable member, said first rotatable member and said second rotatable member being arranged relative to one another for aligning said slot with said extension; and a target forming member coupled to said second rotatable member and displaceable by said second rotatable member between a vertical position and a horizontal position as said second rotatable member is rotated under the influence of said extension within said slot.
Claim 2
Dependent Claim
196 words
A target assembly for use in a target practice range comprising: a carriage base; a motor mounted in said base including a driven shaft, said motor being capable of driving said driven shaft in first and second angular directions; a first rotatable member connected in driven relation with said driven shaft including a first axis of rotation and an extension extending parallel to and radially spaced from said first axis, said extension being arcuately displaceable between a first position and a second position about said first axis with rotation of said rotatable member; a second rotatable member having a second axis of rotation and including a generally radial slot extending from the periphery of said second member towards said second axis and dimensioned for receiving said extension of said first rotatable member, said first rotatable member and said second rotatable member being arranged relative to one another for aligning said slot with said extension; and a target forming member coupled to said second rotatable member and displaceable by said second rotatable member between a vertical position and a horizontal position as said second rotatable member is rotated under the influence of said extension within said slot.
Claim 3
Dependent Claim
88 words
A target assembly in accordance with claim 1 wherein said second rotatable member additionally includes a second slot at the periphery thereof and wherein said target forming member is coupled to said second rotatable member by coupling means mounted to said base, comprising a pivot arm, an arcuate arm having first and second ends, an opening in said first end capturing said pivot arm, a pin extending from said arcuate arm and received by said second slot, and said second end being secured to said target forming member.
Claim 4
Dependent Claim
137 words
A target assembly in accordance with claim 1 wherein said first rotatable member additionally comprises first and second convex peripheral cam surfaces, wherein said second rotatable member includes a first concave peripheral cam surface on one side of said radial slot and a second concave peripheral cam surface on the other side of said slot, said first and second convex cam surfaces being complementary to said first and second concave cam surfaces, respectively, and wherein said first and second rotatable members are arranged for mating said first convex cam surface with said first concave cam surface when said extension is in said first position and for mating said second convex cam surface with said second concave cam surface when said extension is in said second position for locking said target member in the horizontal and vertical positions.
Claim 5
Dependent Claim
71 words
A target assembly in accordance with claim 3 wherein said first rotatable member additionally includes a third concave peripheral cam surface in between said first and second convex cam surfaces, and wherein said extension engages said generally radial slot when said first and third concave cam surfaces are at right angles to thereby free said second rotatable member to rotate under the influence of said extension and said generally radial slot.
Claim 6
Dependent Claim
73 words
A target assembly in accordance with claim 1 further comprising switch means coupled to said motor for applying energizing power to said motor when said switch means are closed and for terminating the application of energizing power to said motor when said switch means are open, and wherein said first rotatable member additionally comprises switch control means for opening said switch means when said extension arrives at said first or said second position.
Claim 7
Dependent Claim
86 words
A target assembly in accordance with claim 5 wherein said switch means comprises first and second normally closed switches having first and second open contact arms, respectively, and wherein said extension of said first rotatable member is arranged relative to said open contact arms for engaging said first open contact arm and for opening said first switch when said extension is in said first position, and for engaging said second open contact arm for opening said second switch when said extension is in said second position.
