  "abstract": "The invention disclosed teaches an arrow straightening machine which includes a nock or head alignment bearing attachment which allows for correction of any eccentricity or misaligmnent between the nock or head and the arrow shaft. The method discloses adhesively bonding the nock or head to the arrow shaft using the attachment device to align while the adhesive is in the unset condition.",
  "claims": [
    "1. An arrow straightening apparatus comprising a base, arrow shaft support means adjustably mounted on said base, and indicator means adjustably mounted on said base for determining any eccentricity or radial irregularity in said arrow shaft, the improvement comprising an attachment for rotatably supporting nocks or heads for placement on said shafts in aligned relationship.",
    "2. An apparatus as in claim 1 wherein said attachment comprises a cylindrical bearing means into which said nocks or heads are received.",
    "3. An apparatus as in claim 1 wherein said attachment is provided with means to mount it on said arrow shaft support means.",
    "4. An apparatus as in claim 1 wherein said base comprises an elongated member provided with a dovetail guide means adapted to slidably receive said arrow shaft support means and said indicator means, each of which are mounted on members having a complimentary dovetail profile.",
    "5. An apparatus as in claim 1 wherein said arrow shaft support means comprises a pair of bearings rotatably mounted on a support block.",
    "6. An apparatus as claim 1 wherein said indicator means is mounted on a shaft straightening mechanism which comprises a support block slidably mounted on said base, an upstanding support post, indicator support bracket means and a bending bar means.",
    "7. An apparatus as in claim 6 wherein said bending bar means is pivotably secured on said support post and said indicator support bracket is slidably disposed on said post.",
    "8. An apparatus as in claim 6 wherein said bending bar means includes a force bushing adapted to engage the arrow shaft to straighten the same.",
    "9. An apparatus as in claim 7 wherein said bending bar means includes spring means to bias it upwardly.",
    "10. A method for using an arrow straightening device to align nocks or heads on arrow shafts, said device comprising a base, arrow shaft support means adjustably mounted on said base, and indicator means adjustably mounted on said base wherein said indicator is shifted to a position along said base to be located outboard of said arrow shaft support means in order to align a nock or head while on said arrow such that any eccentricity or irregularity between said nock or head and said shaft may be detected and proper alignment maintained during attachment of said nock or head and the arrow shaft.",
    "11. A method for adhesively bonding a nock or head to the shaft of an arrow which comprises mounting a nock or head on a first support means for rotation, mounting said arrow shaft on a second support means for rotation, joining said nock or head and said arrow shaft with an unset adhesive therebetween, rotating said joined nock or head and shaft, while rotated, positioning an indicator to detect any misalignment and correcting any said misalignment before said adhesive sets to permanently bond said nock or head and said arrow shaft.",
    "12. A method as in claim 11 wherein the adhesive is of the hot-melt type and heat is applied in order to soften the same to adjust the head or nock while on the shaft to correct any misalignment."

  "description_excerpt": "The invention disclosed in this application relates to arrow straightening and the device described would be used by anyone connected to the shooting of an arrow from a bow or servicing arrows. The type of arrow would be aluminum but should not be limited to that material because the attaching of nocks and heads can be done to any type of arrow material like wood, graphite, plastic, etc. Historically, only aluminum arrows have been straightened by the use of an arrow straightener.\n\nHeretofore, numerous shaft straightening devices have been available in the market place. Each of them with its own means of indicating an eccentricity and a means of elastically deforming and returning the arrow to a striaght condition by way of reverse tension and pressure. Some straighteners used fixed support bearing locations, others do not. It should be noted that graphite, wooden, plastic and some other material arrows are not generally straightened by this means.\n\nEven the most notable of tubing and arrow manufacturers make no provision for accurately attaching nocks and heads to the basic arrow. That is the reason this device was conceived. Current means of attaching nocks and heads call for visual checks for eccentricity. Although we have found that practice to be fairly accurate we have also found the performance of visually inspected arrows to be somewhat unreliable and inconsistent. The straightener we have devised is totally effective with respect to the complete arrow with all components in place. We must admit that the accuracy of the components will have a bearing on the overall accuracy of the arrow.",
