Abstract

The crossbow includes a frame, a first limb and a second limb connected to the frame, a first cam and a second cam mounted on opposite sides of an axis of arrow travel, a string connecting the first cam and the second cam, a first cable connecting the first cam and the first limb, and a second cable connecting the second cam and the second limb. The first cam and the second cam are mounted on a holder of the first cam and a holder of the second cam. The first cam is arranged entirely between the axis of arrow travel and a loose end of the first limb. The second cam is arranged entirely between the axis of arrow travel and a loose end of the second limb. The crossbow reduces overall dimensions of an arrow throwing device while maintaining arrow speed by changing a traditional position of cams.

         4 . The crossbow of  claim 1 ,
 further comprising a foot stirrup connected to the frame;   wherein the at least one first cable further extends to a first side of said foot stirrup; and   wherein the at least one second cable further extends to a second side of said foot stirrup.   
     
     
         5 . The crossbow of  claim 1 ,
 wherein the at least one first cable further extends to a second loose end of the first limb; and   wherein the at least one second cable further extends to a second loose end of the second limb.   
     
     
         6 . A crossbow of  claim 5 ,
 wherein the at least one first cable extends through a first limb holder between the at least one first loose end and the second loose end of the first limb, wherein the first limb holder connects the first limb to the frame; and   wherein the at least one second cable further extends through a second limb holder between the at least one first loose end and the second loose end of the second limb, wherein the second limb holder connects the second limb to the frame.   
     
     
         7 . A crossbow, comprising:
 a frame with an axis of arrow travel extending along said frame;   a first limb being connected to said frame and being comprised of at least one first loose end, wherein the first limb is comprised of two or more limb portions;   a second limb being connected to said frame and being comprised of at least one first loose end, wherein the second limb is comprised of two or more limb portions;   a first cam mounted on a first side of said frame;   a second cam mounted on a second side of said frame, said first side being opposite said second side along said axis of arrow travel;   a first holder between said first cam and said frame, said first cam being mounted on said first holder;   a second holder between said second cam and said frame, said second cam being mounted on said second holder;   a string connected to said first cam and said second cam, said string having a free state and a drawn state;   at least one first cable connected to said first cam and said at least one first loose end of the first limb; and   at least one second cable connected to said second cam and said at least one first loose end of the second limb;   wherein the first cam is arranged entirely between the axis of arrow travel and said at least one first loose end of the first limb, when said string is in said free state;   wherein the second cam is arranged entirely between the axis of arrow travel and said at least one first loose end of the second limb, when said string is in said free state;   wherein said at least one first cable is arranged entirely on said first side; and   wherein said at least one second cable is arranged entirely on said second side.   
     
     
         8 . A bow, comprising:
 a handle having a midpoint and an axis of arrow travel extending through said midpoint and transverse to said handle;   a first limb being connected to said handle and being comprised of at least one first loose end;   a second limb being connected to said handle and being comprised of at least one first loose end;   a first cam mounted on a first side of said handle;   a second cam mounted on a second side of said handle, said first side being opposite said second side at said midpoint of said handle along said axis of arrow travel;   a first holder with said first cam mounted on said first holder;   a second holder with said second cam being mounted on said second holder;   a string connected to said first cam and said second cam, said string having a free state and a drawn state;   at least one first cable extending from said first cam and through said at least one first loose end of the first limb; and   at least one second cable extending from said second cam and through said at least one first loose end of the second limb;   wherein the first cam is arranged entirely between the axis of arrow travel and said at least one first loose end of the first limb, when said string is in said free state;   wherein the second cam is arranged entirely between the axis of arrow travel and said at least one first loose end of the second limb, when said string is in said free state;   wherein said at least one first cable is arranged entirely on said first side; and   wherein said at least one second cable is arranged entirely on said second side.
