Bow string release

A bow string release comprising,

• a body,
• a sear rotatably mounted on the body for movement between a string retaining position and a release position,
• a handle rotatably connected to the body,
• a thrust bearing between the body and the handle,
• a cylindrical plunger rotatably mounted in the body and handle for axial reciprocal motion between a first position in which it engages and retains the sear in said string retaining position and a second position in which it disengages the sear,
• spring means biasing the plunger to said first position,
• means for actuating the plunger to said second position,
• said plunger having a head remote from the plunger end which engages and retains the sear in said string retaining position,
• said actuating means acting on said head,
• said body being a first part and said handle being a second part and said plunger being a third part, said first, second and third parts comprising a group of three parts lying on a common axis;
• each of said parts being rotatable with and with respect to each of the other of said parts of said group.

A bow string release comprising,

• a body,
• a sear rotatably mounted on the body for movement between a string retaining position and a release position,
• a handle rotatably connected to the body,
• a thrust bearing between the body and the handle,
• a plunger mounted in the body and handle for axial reciprocal motion between a first position in which it engages and retains the sear in said string retaining position and a second position in which it disengages the sear,
• spring means biasing the plunger to said first position,
• means for actuating the plunger to said second position,
• a cylindrical portion projecting rearwardly from said body,
• said handle including a sleeve fitting over said cylindrical portion and having an internal shoulder,
• an annular retainer fixed on said cylindrical portion rearwardly of said shoulder,
• a thrust washer between said shoulder and said retainer.

A bow string release comprising,

• a body,
• a sear pivoted on said body for movement between a draw position and a release positon, said sear engaging a string in said draw position and being disengaged from the string in said release positon,
• a handle,
• a thurst bearing rotatably connecting the handle to the body to permit the body to rotate relative to the handle as the handle is drawn rearwardly, the draw force being transmitted through the thrust bearing to said body,
• a rotatable plunger mounted for reciprocal axial motion in the body and handle and having a head remote from the body,
• an adjustable seat in said handle,
• a spring compressed between said plunger head and said seat to adjustably bias the plunger to engage said sear to retain the sear in said draw position,
• an aperture in said handle,
• a trigger pivoted to said handle and projecting through said aperture,
• said trigger having a hole therethrough and said plunger passing through said hole,
• said trigger being engaged by said plunger head and moving said plunger head rearwardly when the trigger is actuated whereby the plunger is moved to release said sear,
• measn for adjusting the trigger movement necessary to move said plunger far enough to release said sear,
• said body being a first part and said handle being a second part and said plunger being a third part, said first, second and third parts comprising a group of three parts lying on a common axis;
• each of said parts being rotatable with and with respect to each of other of said parts of said group.

A bow string release comprising,

• a body, a strong receiving notch therein,
• a seat rotatably mounted on the body for movement between a string retaining position and a release position,
• said sear having a generally U-shape with a long leg which lies across said notch and retains said string in the notch, said sear having a short leg which projects into said notch when the sear is in said string retaining position, said legs being spaced apart far enough to receive a bow string between the legs,
• a handle rotatably connected to the body,
• a thrust bearing between the body and the handle,
• a cylindrical plunger rotatably mounted in the body and handle for axial reciprocal motion between a first position in which it engages said short leg of said sear and retains the sear in said string retaining position and a second position in which it disengages the short leg of the sear,
• spring means biasing the plunger to said first position,
• and means for actuating the plunger to said second position,
• engagement of a bow string with said short leg of said sear when the sear is in said release position being operative to force said short leg into positon to be engaged by said plunger,
• said body being a first part and said handle being a second part and said plunger being a third part, said first, second and third parts comprisinga group of three parts lying on a common axis;
• each of said parts being rotatable with and with respect to each of the other of said parts of said group.
