Recoilless Bucking Bar System
A recoilless bucking bar system that includes a cylindrical housing with a first housing end and a second housing end, a tip adaptor shaft with a neck portion and a mouth portion, a spring, and compression springs. The neck portion has a neck portion first end and a neck portion second end. The neck portion first end is partially disposed within the cylindrical housing. The mouth portion can grip a bucking bar tip. The gripped bucking her tip is able to be inserted in a space such that the system can be used as a bucking bar. The spring is axially disposed within the cylindrical housing at the second housing end. The spring communicates with the neck portion first end, and is axially aligned to the tip adaptor shaft. The compression springs are disposed around the circumference of the neck portion that is partially disposed within the cylindrical housing.

BACKGROUNDA bucking bar is used when two or more pieces of material are joined together with a rivet. A rivet is a fastener that is placed in a hole through the materials. Typically an air hammer is placed on the rounded head of a rivet and the bucking bar is placed on the straight shaft of the rivet on the opposite side. Force is then applied by the hammer, and the bucking bar rounds over that end, joining the pieces together.
Typical bucking bars do not absorb any vibrations, but instead amplify the vibration. This causes discomfort and possible injury to the user. Therefore, there is a need for a recoilless bucking bar system that reduces vibrations.
SUMMARYThe present invention is directed to a recoilless bucking bar system that meets the needs enumerated above and below.
The present invention is directed to a recoilless bucking bar system that includes a cylindrical housing, a tip adaptor shaft, a spring, and compression springs. The cylindrical housing has a first housing end and a second housing end. The tip adaptor shaft has a neck portion and a mouth portion. The neck portion has a neck portion first end and a neck portion second end. The neck portion first end is partially disposed within the cylindrical housing at the first housing end. The mouth portion is located at the neck portion second end and is able to grip a bucking bar tip. The gripped bucking bar tip is able to be inserted in a space such that the system can be used as a bucking bar. The spring is axially disposed within the cylindrical housing at the second housing end. The spring communicates with the neck portion first end, and is axially aligned to the tip adaptor shaft. The compression springs are disposed around the circumference of the neck portion that is partially disposed within the cylindrical housing.
It is a feature of the present invention to provide a recoilless bucking bar system does not amplify vibrations.
It is a feature of the present invention to provide a recoilless bucking bar system that absorbs vibrations.

Claims
1. A recoilless bucking bar system, comprising:
- a cylindrical housing, the cylindrical housing having a first housing end and a second housing end;
- a tip adaptor shaft comprising a neck portion, a mouth portion and a circumference, the neck portion having a neck portion first end and a neck portion second end, the neck portion first end partially disposed within the cylindrical housing at the first housing end, the mouth portion located at the neck portion second end and able to grip a bucking bar tip, the tip being able to be inserted in a space such that the system can be used as a bucking bar;
- a spring, the spring axially disposed within the cylindrical housing at the second housing end and axially aligned to the tip adaptor shaft; and,
- compression springs disposed around the circumference of the neck portion that is partially disposed within the cylindrical housing.
2. The recoilless bucking bar system of claim 1, wherein the bucking bar tip includes a threaded extension, the tip adaptor shaft includes a threaded bore disposed at the neck portion second end such that the threaded bore corresponds to the threaded extension allowing attachment.
3. The recoilless bucking bar system of claim 2, wherein the system further includes interchangeable bucking bar tips.
4. The recoilless bucking bar system of claim 3, wherein the tip adapter shaft includes an annular flange and an annular boss, the annular flange and the annular boss axially aligned to the neck portion, the cylindrical housing being hollow and having an internal diameter allowing the annular flange to slide along the diameter of the cylindrical housing, the annular boss communicating with the spring such that the spring can act upon the tip adapter shaft.
