Abstract
Abstract Artificial feathers for arrows each of which is of a one-piece construction and of a soft flexible material such as plastic. Rather than being molded into a solid piece, each feature has individual barbs that are shaped so that they normally nest with one another. However, the barbs allow each feather to collapse as it passes the bow and then spring back into normal shape to guide the arrow in flight.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
181 words
An artificial guiding feather for use on arrows and the like, said feather comprising an elongated base having a forward end and a rear end and an outer surface shaped to fit an arrow, and a row of independent barbs along said base between the ends thereof, each of said barbs being joined at one end to said base and extending outwardly and rearwardly therefrom, said barbs and base being of one-piece construction of a flexible and resilient plastic material with the barbs being of substantially the same width and all located in substantially the same plane; each of said barbs in transverse cross-section having a forwardly extending end and a pair of rearwardly extending vanes; said barbs having parallel front and rear surfaces; each of said vanes having the same cross-sectional area, the front and rear surfaces of each pair of vanes being spaced apart along the longitudinal axis of said barbs thereby forming a notch in the barb of said pair of vanes at the intersection of said pair of vanes, said front surfaces forming an acute angle therebetween.
Claim 2
Dependent Claim
181 words
An artificial guiding feather for use on arrows and the like, said feather comprising an elongated base having a forward end and a rear end and an outer surface shaped to fit an arrow, and a row of independent barbs along said base between the ends thereof, each of said barbs being joined at one end to said base and extending outwardly and rearwardly therefrom, said barbs and base being of one-piece construction of a flexible and resilient plastic material with the barbs being of substantially the same width and all located in substantially the same plane; each of said barbs in transverse cross-section having a forwardly extending end and a pair of rearwardly extending vanes; said barbs having parallel front and rear surfaces; each of said vanes having the same cross-sectional area, the front and rear surfaces of each pair of vanes being spaced apart along the longitudinal axis of said barbs thereby forming a notch in the barb of said pair of vanes at the intersection of said pair of vanes, said front surfaces forming an acute angle therebetween.
Claim 3
Dependent Claim
49 words
The feather of claim 1 in which the said barbs are longitudinally positioned with the forward end of one extending into the space between the vanes of the forwardly adjacent barb so that lateral movement of one of said barbs will be resisted by engagement with the adjacent barbs.
Claim 4
Dependent Claim
52 words
The feather of claim 1 in which the rear surfaces of said pair of vanes form an obtuse angle therebetween and the front surfaces of said vanes form a shoulder at their intersection, and the shoulder on one barb is adapted to be received in the notch of the barb adjacent thereto.
Claim 5
Dependent Claim
49 words
The feather of claim 3 in which the said barbs are longitudinally positioned with the forward end of one extending into the space between the vanes of the forwardly adjacent barb so that lateral movement of one of said barbs will be resisted by engagement with the adjacent barbs.
