The system is designed to operate by purely mechanical means and without power, and is launch speed and launch angle adjustable. The action of the system is such that the arming mechanism may be engaged by a user to apply tension on the cradle mechanism and drive mechanism. The user may then place a ball into the cradle mechanism, and may launch the ball from the system by engaging the firing mechanism. The engaging of the firing mechanism releases the tension in the system, causing the cradle mechanism to accelerate the ball into the air. The entire system is contained within the main body, which is designed to provide an easily moveable, lightweight, and low maintenance solution for achieving such a purpose. ## Claims ### Claim 1 A mechanical sports ball catapult system, comprising: a structural main body; an arming mechanism; a cradle mechanism; a drive mechanism; and a firing mechanism; wherein said arming mechanism, said drive mechanism, said cradle mechanism, and said firing mechanism are attached to said structural main body; wherein said structural main body further comprises a plurality of side panels, a rear panel, a plurality of cradle support frames, a plurality of vertical frames, a plurality of horizontal frames, an axle, and a plurality of wheels; wherein a first of said plurality of vertical frames is attached to a first end of each of said plurality of horizontal frames, and a second of said plurality of vertical frames is attached to a second end of each of said plurality of horizontal frames; wherein an upper end of each of said plurality of cradle support frames is attached to an upper end of each of said plurality of vertical frames, and a lower end of each of said plurality of cradle support frames is attached to a front end of said plurality of horizontal frames; and wherein said plurality of cradle support frames, said plurality of vertical frames, and said plurality of horizontal frames comprise a system skeleton. ### Claim 2 (depends on 1) The invention of claim 1, wherein said axle is installed through a lower end of each of said plurality of vertical frames; wherein a first of said plurality of wheels is attached to a first end of said axle; and wherein a second of said plurality of wheels is attached to a second end of said axle. ### Claim 3 (depends on 2) The invention of claim 2, wherein said arming mechanism further comprises an arming pedal, a plurality of arming pedal arms, an arming cord, and a retaining ball; wherein a first end of said arming pedal is attached to a first end of a first of said plurality of arming pedal arms, and a second end of said arming pedal is attached to a first end of a second of said plurality of arming pedal arms; and wherein a first end of said arming cord is attached to said arming pedal. ### Claim 4 (depends on 3) The invention of claim 3, wherein said cradle mechanism further comprises a cradle, a plurality of cradle tensioning cords, a plurality of fasteners, and a plurality of cradle angle brackets; wherein a first end of each of said plurality of cradle tensioning cords is attached to said cradle; and wherein a second end of each of said plurality of cradle tensioning cords is attached to one each of said plurality of fasteners. ### Claim 5 (depends on 4) The invention of claim 4, wherein said drive mechanism further comprises a drive piston arm, a drive carriage, a plurality of drive carriage sliders, and a means for drive tensioning; wherein said drive piston arm is attached to said drive carriage; wherein said drive carriage slides along said plurality of drive carriage sliders; and wherein said drive carriage is attached to said means for drive tensioning. ### Claim 6 (depends on 5) The invention of claim 5, wherein said firing mechanism further comprises a firing mechanism cover, a firing piston arm, a firing carriage, a plurality of firing carriage rails, a means for firing tensioning, and a spool cable; wherein said firing piston arm is attached to said firing carriage; wherein said firing carriage slides along said plurality of firing carriage sliders; wherein said firing carriage is attached to said means for firing tensioning; and wherein a first end of said spool cable is attached to said means for firing tensioning. ### Claim 7 (depends on 6) The invention of claim 6, wherein said retaining ball is attached to a middle portion of said arming cord; wherein said retaining ball is placed within said arming mechanism; wherein a second end of said arming cord is attached to said cradle; wherein a second end of said spool cable is attached to a drive tension release attached to said drive carriage; and wherein each of said plurality of fasteners is attached to said plurality of cradle angle brackets; and wherein one each of said plurality of cradle angle brackets is attached to one each of said plurality of cradle support frames. ### Claim 8 (depends on 7) The invention of claim 7, wherein a user activates said arming mechanism by moving said arming pedal; wherein said moving of said arming pedal activates said arming cord; wherein said activation of said arming cord moves said retaining ball; wherein said moving of said retaining ball activates said drive piston arm; wherein said activating of said drive piston arm slides said drive carriage and increases a tension within said means for drive tensioning; wherein said activation of said arming cord pulls said cradle; wherein said pulling of said cradle increases a tension in each of said plurality of cradle tensioning cords; wherein said sliding of said drive carriage pulls said spool cable; and wherein said pulling of said spool cable slides said firing carriage and increases a tension within said means for firing tensioning. ### Claim 9 (depends on 8) The invention of claim 8, wherein a user activates said firing mechanism by moving said firing mechanism cover; wherein said moving of said firing mechanism cover releases said tension within said means for firing tension; wherein said release of tension within said means for firing tension activates said drive tension release; wherein said activation of said drive tension release releases said tension within said means for drive tensioning; and wherein said release of tension within said means for drive tensioning releases said tension in each of said plurality of cradle tensioning cords. ### Claim 10 (depends on 9) The invention of claim 9, wherein each of said cradle angle brackets further comprises a means for angle adjustment; wherein each of said cradle support frames further comprises a means for receiving angle adjustments; wherein one each of said cradle angle brackets is attached to one each of said cradle support frames by a sliding mechanism; and wherein a relative position of said cradle angle brackets on said cradle support frames may be adjusted by moving said means for angle adjustment from a first means for receiving angle adjustments to a second means for receiving angle adjustments. ### Claim 11 (depends on 10) The invention of claim 10, wherein a first of said plurality of side panels is attached to a first outer side of said system skeleton; wherein a second of said plurality of side panels is attached to a second outer side of said system skeleton; and wherein said rear panel is attached to a rear side of said system skeleton. ### Claim 12 (depends on 11) The invention of claim 11, further comprising: a handgrip; wherein said handgrip is installed through an upper end of each of said plurality of vertical frames. ### Claim 13 (depends on 12) The invention of claim 12, wherein said tension in each of said plurality of cradle tensioning cords is adjustable. ### Claim 14 (depends on 12) The invention of claim 12, wherein said tension in said means for drive tensioning is adjustable. ### Claim 15 (depends on 12) The invention of claim 12, wherein said tension in said means for firing tensioning is adjustable.
