1. A crossbow trigger apparatus comprisinga housing;

  • a first lever operationally engaged with the housing to pivot about a first pivot axis between an actuated orientation and an unactuated orientation,the first pivot axis being fixed in a first location with respect to the housing,the first lever being elongated to define a first end of the first lever and a second end of the first lever opposite the first end of the first lever;

    a second lever operationally engaged with the housing to pivot about a second pivot axis between an actuated orientation and an unactuated orientation,the second pivot axis being fixed in a second location with respect to the housing,the second location being offset from the first location,the second lever being elongated to define a first end of the second lever and a second end of the second lever opposite the first end of the second lever;

    a third lever operationally engaged with the housing to pivot about a third pivot axis between an actuated orientation and an unactuated orientation,the third pivot axis being fixed in a third location with respect to the housing, the third locationbeing offset from the first location, andbeing offset from the second location,the third lever being elongated and U-shaped to define a first end of the third lever and a second end of the third lever opposite the first end of the third lever,the third lever being adapted,when in the unactuated orientation, to retain an associated cocked bowstring, andwhen in the actuated orientation, to release an associated cocked bowstring;

    a fourth lever operationally engaged with the housing to pivot about a fourth pivot axis between an actuated orientation and an unactuated orientation,the fourth pivot axis being fixed in a fourth location with respect to the housing,the fourth locationbeing offset from the first location,being offset from the second location, andbeing offset from the third location,the fourth lever being elongated to define a first end of the fourth lever and a second end of the fourth lever opposite the first end of the fourth lever;

    wherein the fourth lever comprises a fourth lever catch adapted to selectably engage the second lever to prevent the second lever from operating to move from the unactuated orientation of the second lever to the actuated orientation of the second lever when the fourth lever is in the unactuated orientation of the fourth lever;

    wherein the second lever comprises a second lever catch adaptedto selectably engage the third lever, andto prevent the third lever from operating to move from the unactuated orientation of the third lever to the actuated orientation of the third lever when the second lever is in the unactuated orientation of the second lever; and

    wherein the fourth lever is adapted to be moved from the unactuated orientation of the fourth lever to the actuated orientation of the fourth lever by an associated arrow being operationally engaged with the crossbow trigger apparatus;

    wherein the fourth lever is engaged with a fourth lever spring that biases the fourth lever to the unactuated orientation of the fourth lever;

    wherein the third lever adapted to be rotated from the actuated orientation of the third lever to the unactuated orientation of the third lever by cocking an associated bowstring;

    wherein the second lever is engaged with a second lever spring that biases the second lever to the unactuated orientation of the second lever;

    wherein the first lever is engaged with a first lever spring that biases the first lever to the unactuated orientation of the first lever;

    wherein the fourth lever comprises a manual decocking lobe projecting radially from the fourth pivot axis adapted to permit an associated user to selectably move the fourth lever from the unactuated orientation of the fourth lever to the actuated orientation of the fourth lever; and

    wherein the second lever and the fourth lever contact one another in both the actuated orientation and the unactuated orientation.
