Each of the limbs has forward ends extended from the main riser frame. A bowstring has wound ends that are wound onto each of wheel cams that are attached to the limbs. The bowstring has a middle section that is not wound onto the wheel cams and that begins and ends at points on the wheel cams that are proximate to the farthest points along the wheel cams from the main riser frame. An elongate tube is mounted to the main riser frame through the central bore, and has a front handle attached to the elongate tube outer surface, and positioned between the first and second pairs of limbs. A push rod is slidably mounted at least partially inside the elongate tube, and has a rearward handle disposed outside the elongate tube rearward end. ## Claims ### Claim 1 An archery bow, comprising: a main riser frame having a central bore; a first and second pair of limbs extending from the main riser frame, each of the limbs having rearward ends attached to the main riser frame, and forward ends extended apart from the main riser frame, the bow being configured to be operated with the first and second pair of limbs and the main riser frame in a substantially vertical plane; first and second wheel cam assemblies, each comprising first and second wheel cams; first and second axles rotatably mounting the first and second wheel cam assemblies to the respective first and second pair of limbs approximate their forward ends; a bowstring having wound ends that are wound onto each of the first wheel cams, and having a middle section that is not wound onto the first wheel cams and that begins and ends at points on the first wheel cams that are proximate to the farthest points along the first wheel cams from the main riser frame; a first spring bowstring having a first end wound on the second wheel cam from the first wheel cam assembly, and having a second end wound on the second axle mounting the second wheel assembly; a second spring bowstring having a first end wound on the second cam wheel from the second wheel cam assembly, and having a second end wound on the first axle mounting the first wheel assembly; an elongate tube mounted to the main riser frame through the central bore, the elongate tube having forward and rearward ends; a front handle attached to the elongate tube outer surface and positioned between the first and second pairs of limbs; and a push rod slidably mounted at least partially inside the elongate tube and having a rearward handle disposed outside the elongate tube rearward end. ### Claim 2 (depends on 1) The archery bow according to claim 1, further comprising: a string dampener attached to the elongate tube outer surface and positioned between the bowstring middle section and the elongate tube forward end. ### Claim 3 (depends on 1) The archery bow according to claim 1, further comprising: an arrow retainer assembly attached adjacent to the elongate tube forward end. ### Claim 4 (depends on 3) The archery bow according to claim 3, wherein the arrow retainer comprises three approximately equally-spaced members converging around an arrow pathway. ### Claim 5 A hand-drawn archery bow, comprising: a main riser frame having a first end and a second end, and further having a forward side and a rearward side; a first limb extending from the main riser frame first end, and a second limb extending from the main riser frame second end, each of the first and second limbs having a rearward end attached to the main riser frame, and a forward end extended apart from the main riser frame; a first wheel cam assembly rotatably mounted to the first limb proximate to its forward end, and a second wheel cam assembly rotatably mounted to the second limb proximate to its forward end; and a bowstring having wound ends that are wound onto the first and second wheel cam assemblies, and having a middle section between the wound ends, wherein the bowstring and main riser frame are in relation with each other to have a relaxed configuration in which the bowstring middle section extends linearly between the first and second wheel cam assemblies, and a hand-drawn configuration in which the bowstring middle section extends across the main riser frame, and wherein the archery bow is devoid of a locking mechanism that can maintain the bowstring in the hand-drawn configuration; and a forward handle extending from the main riser frame to a position on the forward side of the main riser frame. ### Claim 6 (depends on 5) The hand-drawn archery bow according to claim 5, wherein the forward handle is disposed between the main riser frame and the bowstring when the archery bow is in the relaxed configuration. ### Claim 7 (depends on 5) The hand-drawn archery bow according to claim 5, further comprising an elongate tube extending from the main riser frame on the forward side, and having the forward handle supported thereon. ### Claim 8 (depends on 5) The hand-drawn archery bow according to claim 5, further comprising: a rear handle extending from the main riser frame on the rearward side of the main riser frame. ### Claim 9 (depends on 8) The hand-drawn archery bow according to claim 8, wherein the rear handle is retractably positionable at various distances from the main riser frame on the rearward side of the main riser frame. ### Claim 10 (depends on 5) The hand-drawn archery bow according to claim 5, wherein the bowstring middle section is not wound onto the first and second wheel cam assemblies, and begins and ends at points on the first and second wheel cam assemblies that are proximate to points along the first wheel cams that are farthest from the main riser frame. ### Claim 11 A hand-drawn archery bow, comprising: a main riser frame having a first end and a second end, and further having a forward side and a rearward side; a first limb extending from the main riser frame first end, and a second limb extending from the main riser frame second end, each of the first and second limbs having a rearward end attached to the main riser frame, and a forward end extended apart from the main riser frame; a first wheel cam assembly rotatably mounted to the first limb proximate to its forward end, and a second wheel cam assembly rotatably mounted to the second limb proximate to its forward end; a bowstring having wound ends that are wound onto the first and second wheel cam assemblies, and having a middle section between the wound ends; and a forward handle extending from the main riser frame to a position on the forward side of the main riser frame, wherein the forward handle is disposed between the main riser frame and the bowstring middle section when the archery bow is in the relaxed configuration wherein the bowstring and main riser frame are in relation with each other to have a relaxed configuration in which the bowstring middle section extends linearly between the first and second wheel cam assemblies, and a hand-drawn configuration in which the bowstring middle section extends across the main riser frame. ### Claim 12 (depends on 11) The hand-drawn archery bow according to claim 11, further comprising an elongate tube extending from the main riser frame on the forward side, and having the forward handle supported thereon. ### Claim 13 (depends on 11) The hand-drawn archery bow according to claim 11, further comprising: a rear handle extending from the main riser frame on the rearward side of the main riser frame. ### Claim 14 (depends on 13) The hand-drawn archery bow according to claim 13, wherein the rear handle is retractably positionable at various distances from the main riser frame on the rearward side of the main riser frame. ### Claim 15 (depends on 11) The hand-drawn archery bow according to claim 11, further comprising: a bowstring having wound ends that are wound onto the first and second wheel cam assemblies, and having a middle section that is not wound on the first and second wheel cam assemblies, and begins and ends at points on the first and second wheel cam assemblies that are proximate to points along the first wheel cams that are farthest from the main riser.
