Pull tension archery release

1. A pull tension archery release, comprising

(a) a head;

(b) a bail connected with said head for rotation about a first axis, said bail including at least one radially extending projection configured to hold a bow string;

(c) a sear assembly operable between a hold position wherein said sear assembly engages said bail to prevent rotation of said bail and a release position wherein said sear assembly releases said bail for rotation to release the bow string and fire an arrow; and

(d) a locking assembly connected with said head and said sear assembly to lock said head in a fixed position relative to said housing.

2. An archery release as defined in claim 1 , and further comprising a cylindrical housing having a longitudinal axis and connected with said head, said sear assembly being arranged in said housing.

3. An archery release as defined in claim 2 , wherein said sear assembly includes a sear arranged within housing and along said longitudinal axis, said sear having a first end configured to engage and release said bail, whereby when pull tension is applied to said sear, said sear is displaced away from said bail to release the bow string.

4. An archery release as defined in claim 3 , and further comprising a cylindrical pull sleeve containing a chamber, said housing being coaxially arranged in said pull sleave chamber, said pull sleave being connected with a second end of said sear.

5. An archery release as defined in claim 3 , wherein said sear includes an annular recess and said locking assembly includes a finger lock pivotally connected with said head, one end of said finger lock being configured to engage said sear recess in a locked position.

6. An archery release as defined in claim 5 , and further comprising a thumb lock rotatably connected with said head opposite said finger lock, one end of said thumb lock configured to engage said sear recess in a locked position.

7. An archery release as defined in claim 3 , and further comprising a spring arranged within said housing between said sear and said housing, said spring biasing said sear toward the hold position.

8. An archery release as defined in claim 7 , and further comprising an adjustable nut arranged within said housing and abutting against said spring, said nut being threadably connected with said housing and operable to adjust a biasing force of said spring on said sear.

9. A pull tension archery release, comprising

(a) a head;

(b) a bail connected with said head for rotation about a first axis, wherein said bail includes three equally spaced radially extending projections configured to hold a bow string; and

(c) a sear assembly operable between a hold position wherein said sear assembly engages said bail to prevent rotation of said bail and a release position wherein said sear assembly releases said bail for rotation to release the bow string and fire an arrow.

10. A pull tension archery release, comprising

(a) a housing having a longitudinal axis and containing a chamber;

(b) a sear assembly configured for engaging a bow string, said sear assembly including a sear arranged within said housing chamber for reciprocal movement along said longitudinal axis between hold and release positions, whereby when pull tension is applied to said sear with said sear assembly engaging the bow string, said sear is displaced to release the bow string; and

(c) a locking assembly engaging said sear to lock and release said sear to prevent and permit reciprocal movement, respectively, of said sear relative to said housing.

11. A pull tension archery release as defined in claim 10 , wherein said sear assembly further includes a head connected with said sear for movement with said sear relative to said housing.

12. A pull tension archery release as defined in claim 11 , and further comprising a bail connected with said head for rotation about an axis normal to said longitudinal axis and including at least one radially extending projection engaged by a first end of said sear when said sear is in said hold position, whereby when said sear is displaced to said release position, said bail rotates to release the bow string.

13. A pull tension archer release as defined in claim 12 , wherein said bail includes three equally spaced projections.

14. A pull tension archery release as defined in claim 10 , and further comprising a spring arranged in said housing chamber between said sear and said housing, said spring being coaxial with and surrounding a portion of said sear and biasing said sear toward the hold position.

15. A pull tension archery release as defined in claim 14 , and further comprising a nut arranged in said housing chamber and threadably connected with said housing to adjust a biasing force of said spring on said sear.

16. A pull tension archery release as defined in claim 10 , and further comprising a pull sleeve connected with a second end of said sear and operable by an archer to apply pull tension to said sear.
