Abstract: A linear jack includes a coarse nut threadedly coupled to a first rotating screw and a first sleeve mounted to the coarse nut (the first rotating screw, the first sleeve, and the coarse nut collectively a high-speed assembly), and a second sleeve threadedly coupled to a second rotating screw (the second sleeve and the second rotating screw collectively a low-speed assembly). The coarse nut is configured to operate in a first mode where the coarse nut is held from rotating with the first rotating screw to convert rotational motion of the first rotating screw into translating motion of the coarse nut and the first sleeve. The coarse nut is configured to operate in a second mode where the coarse nut rotates with the first rotating screw so that only the low-speed assembly operates to extend the second sleeve.

Abstract: A linear jack includes a coarse nut threadedly coupled to a first rotating screw and a first sleeve movable with respect to the coarse nut (the first rotating screw, the first sleeve, and the coarse nut collectively a high-speed assembly), and a second sleeve threadedly coupled to a second rotating screw (the second sleeve and the second rotating screw collectively a low-speed assembly). The coarse nut is movable to a first position where the coarse nut is held from rotating with the first rotating screw—e.g., via a dog clutch—to convert rotational motion of the first rotating screw into translating motion of the coarse nut and the first sleeve. The coarse nut is movable to a second position where the coarse nut is free to rotate together with the second rotating screw and the first rotating screw with respect to the first sleeve.

Abstract: A linear jack includes an outer sleeve, an inner sleeve disposed at least partially within the outer sleeve, and an inner screw disposed at least partially within the inner sleeve. The outer sleeve is threadedly coupled to an outer diameter surface of the inner sleeve. The inner screw is threadedly coupled to an inner diameter surface of the inner sleeve. A thread pitch of the outer sleeve is greater than a thread pitch of the inner screw.

Abstract: A compound bow may feature the ability to pre-store energy before the drawing back of the draw string. Various embodiments contemplate that this may allow an archer to draw back the draw string or cable, and upon reaching the let off region of the compound bow's draw profile, cause the pre-stored energy to be transferred to the energy being stored by the bow. Various embodiments contemplate that this addition of pre-stored energy may give the archer more energy, held in the draw string or cable, to transfer to an arrow upon release, propelling it at greater speeds than would have been achieved with a compound bow of equal draw weight that does not feature an energy storage mechanism. Various embodiments contemplate that a system may provide for a return position of the draw.

Abstract: A linear jack includes a first sleeve disposed at least partially within a second sleeve (the first sleeve and the second sleeve collectively a high speed assembly), a third sleeve disposed at least partially within the first sleeve, and a translating screw disposed at least partially within the third sleeve (the third sleeve and the translating screw collectively a low speed assembly). The linear jack further includes a fourth sleeve fixed to the second sleeve and configured to translate therewith. The fourth sleeve extends over the third sleeve and transfers axial loads between the second sleeve and the third sleeve to extend the high speed assembly together with the low speed assembly from an outer case of the linear jack.
