Compound archery bow

A spring loaded compound archery bow comprising;

• a bow riser having a handle portion, a top end, a bottom end wherein said bow riser generally extends vertically between said top and bottom ends;
• a first spring housing mounted relative to said top end, said first spring housing having a first elongated inner cavity extending along a first inner cavity axis;
• a second spring housing mounted relative to said bottom end, said second spring housing having a second elongated inner cavity extending along a second inner cavity axis;
• a first compression spring positioned within said first elongated inner cavity of said first spring housing, said first compression spring extending along a first linear spring axis between a first forward end and a first reward end, said first compression spring being axial compressible along said first linear spring axis and having a rearwardly exposed first spring end cap;
• a second compression spring positioned within said second elongated inner cavity of said second spring housing, said second compression spring extending along a second linear spring axis between a second forward end and a second reward end, said second compression spring being axial compressible along said second linear spring axis and having a rearwardly exposed second end cap;
• a first crank support fixed relative to said first spring housing that rotatably supports a first crank about a first support axis, said first crank having a first crank arm including a first extension spaced from said first support axis that is engagable against said first end cap when said first crank rotates about said first axis;
• a second crank support fixed relative to said second spring housing that rotatably supports a second crank about a second support axis, said second crank having a second crank arm including a second extension spaced from said second support axis that is engagable against said second end cap when said second crank rotates about said second axis, said first and second axes being spaced from one another;
• a first rotatable bow string support attached to said first crank for rotation thereon, said first rotatable string support having a first outwardly facing guide groove;
• a second rotatable bow string support attached to said second crank for rotation thereon, said second rotatable string support having a second outwardly facing guide groove;
• and,
• a bow string joined between said first and second rotatable bow string supports and said first and second outwardly facing guide grooves being shaped to guide said bow string about said rotatable bow string supports as said supports rotate relative to said respective cranks such that when said bow string is pulled back for shooting an associated arrow, said first rotatable bow string support rotates about said first crank and said first crank rotates about said first support axis and said first extension linearly compresses said first compression spring along said first spring axis while said second rotatable bow string support rotates about said second crank and said second crank rotates about said second support axis and said second extension linearly compresses said second compression spring, the compression of said first and second compression springs providing an amount of stored energy to propel the associate arrow and one of said first and second rotatable bow string support providing at least one of increasing said amount of stored energy and reducing a holding force for the shooter when said bow is at full draw.
