A pair of elastomeric members are each attached at one end to a projectile holder and at the other end to one of a plurality of spaced open slots on opposite sides of the main body portion. The elastomeric members pass about spaced rotatable pulleys mounted in each free end of the spaced arms. ## Claims ### Claim 1 In a portable catapult device including a projectile holding member, two elongated laterally spaced elastomeric members secured to opposite ends of said holding member, a housing having spaced elongated sides and a pair of spaced arms extending outwardly from a main body portion, said free ends of said elastomeric members being attached to opposite sides of said holding member, said main body portion having an integral downwardly extending pistol-type handle, the improvement which comprises: a pair of pulleys rotatably mounted on the extreme forwardly extending ends of said arms, said elastomeric members extending about respective ones of said arms; and a plurality of spaced slotted holes provided on each side of said main body portion, a first one of said spaced slotted holes on one side of said main body portion being aligned with a first one of said spaced slotted holes on the other side of said main body portion, and at least a second one of said spaced slotted holes on one side of said main body portion being aligned with a second one of said spaced slotted holes on the other side of said main body portion, one of said free ends of said elastomeric member being secured in one of said aligned slotted holes on one side of said main body portion and the other of said free ends of said elastomeric members being secured in one of said aligned slotted holes on the other side of said main body portion. ### Claim 2 (depends on 1) In the device of claim 1 wherein each of said arms terminate in a slot, said pulleys being pivotally mounted in respective ones of said slots, the axis of rotation of each pulley being perpendicular to the plane of said housing, each of said pulleys rotating in a plane generally normally to said axis. ### Claim 3 (depends on 2) In the device of claim 2 wherein the overall length of said slots is about 11/2 inches. ### Claim 4 (depends on 1) In the device of claim 1 wherein the depth of said slotted holes on said arms is about 3/8 inches. ### Claim 5 (depends on 1) In the device of claim 1 wherein the rearward end of said main body portion curves arcuately and downwardly for conforming to the arm of a user. ### Claim 6 (depends on 5) In the device of claim 5 wherein the interior of said curved portion is cushioned. ### Claim 7 (depends on 1) In the device of claim 1 wherein said elastomeric members are hollow rubber tubings and one free end of one of said elastomeric members is attached to said housing by a ball inserted into the free open end thereof of a diameter greater than spacings in said housing through which said elastomeric members extend, and the free end of the other of said elastomeric members being attached to said housing by a ball inserted into the free open end of the last mentioned elastomeric member and also of a diameter greater than the spacings in said housing through which said elastomeric members extend, said balls being disposed on opposite sides of said housing. ### Claim 8 (depends on 1) In the device of claim 1 wherein each of said elastomeric members is a flexible hollow tube extending through a hole in said holding member and secured therein. ### Claim 9 (depends on 1) In the device of claim 1 wherein each of said elastomeric members is attached to said housing by extending through spaced slots on opposite sides of said main body portion, said spaced slots being open to the exterior of said main portion and of a diameter sufficient to receive said free ends of said elastomeric members therein. ### Claim 10 (depends on 9) In the device of claim 9 including retaining means mounted in the free ends of said elastomeric members for retaining the same in said slots.
