Abstract
A two-piece, laminated-limb, take-down bow and a process for making such a bow is described. In brief, the bow comprises: an upper laminated-limb, having a sight-window formed therein and an outer diameter defined under the sight-window; a metal female sleeve having an outer diameter larger than the diameter of the upper laminated-limb; a first amount of shock-absorbing epoxy residing between a portion of the interior of the metal female sleeve and the upper laminated-limb; a lower laminated-limb; a metal male sleeve having an outer diameter smaller than the inner diameter of the female sleeve and capable of slidable insertion therein; a second amount of shock-absorbing epoxy residing between a substantially all of the interior of the metal male sleeve and the lower laminated-limb.
Claims29
A two-piece, take-down bow using laminated-limbs, comprising:
- an upper laminated-limb, having a sight-window formed therein and an outer diameter defined under the sight-window;
- a metal female sleeve having an inner diameter larger than the outer diameter of the upper laminated-limb;
- a first amount of shock-absorbing epoxy residing between a portion of the interior of said metal female sleeve and said upper laminated-limb;
- a lower laminated-limb;
- a metal male sleeve capable of slidable insertion in said female sleeve;
- and
- a second amount of shock-absorbing epoxy residing between substantially all of the interior of said metal male sleeve and said lower laminated-limb.
A process for manufacturing a two-piece, take-down, laminated-limb bow comprising the steps of:
- inserting a stainless-steel tube into a brass alloy tube, wherein the brass alloy tube is hotter than the tube of stainless-steel;
- causing the temperature of the stainless-steel tube and the brass alloy tube to be substantially the same;
- flattening a portion of the brass alloy tube, whereby a substantially flat surface substantially parallel to the axis of the brass alloy tube is defined;
- forming two non-parallel lateral aspects in the outer diameter of the brass alloy tube, whereby said flattening the portion of the brass alloy tube and forming two non-parallel lateral aspects in the outer diameter of the brass alloy tube define a brass alloy sleeve;
- flattening a portion of a stainless-steel tube, whereby a substantially flat surface substantially parallel to the axis of the stainless-steel tube is defined;
- forming two non-parallel lateral aspects in the outer diameter of the stainless-steel tube, wherein said flattening the portion of the portion of the stainless-steel tube and said forming two non-parallel lateral aspects in the outer diameter of the stainless-steel tube define a stainless-steel sleeve;
- attaching the brass alloy sleeve to a first laminated bow limb;
- and
- attaching the stainless-steel sleeve to a second laminated bow limb.
A process for manufacturing a two-piece, take-down bow comprising the steps of:
- heating a brass alloy tube,
- expanding the brass alloy tube, and
- sliding a stainless-steel tube into the brass alloy tube,
- causing the temperature of the stainless-steel tube and the brass alloy tube to be substantially the same;
- flattening, while the stainless-steel tube is still inserted in the brass alloy tube, a portion of the brass alloy tube, whereby a substantially flat surface substantially parallel to the axis of the brass alloy tube is defined in the brass tube, and whereby a second substantially flat surface is defined in the stainless-steel tube substantially parallel to the axis of the stainless-steel tube;
- forming, while the stainless-steel tube is still inserted in the brass alloy tube, a first pair of non-parallel lateral aspects in the outer diameter of the brass alloy tube, whereby a second pair of non-parallel lateral aspects are defined in the outer diameter of the stainless-steel tube, whereby said flattening and forming define a brass alloy sleeve and a stainless-steel sleeve, repeatedly heating and water quenching the brass alloy tube until the brass alloy tube and the stainless-steel tube separate under the force of gravity;
- aligning the first substantially flat surface with a substantially flat portion of the laminated bow limb;
- inserting the aligned laminated bow limb into a laminated-limb portion of the brass alloy sleeve;
- gluing the inserted laminated bow limb to the laminated-limb portion of the brass alloy sleeve with an anaerobic adhesive;
- inserting shrinkless, shock resistant filler epoxy between the brass alloy sleeve and the laminated bow limb;
- aligning the second substantially flat surface with a substantially flat portion of the laminated bow limb;
- inserting the aligned laminated bow limb into a laminated-limb portion of the stainless-steel sleeve;
- gluing the inserted laminated bow limb to the laminated-limb portion of the stainless-steel sleeve with an anaerobic adhesive;
- and
- inserting shrinkless, shock resistant filler epoxy between the stainless-steel sleeve and the laminated bow limb.
