Abstract

Abstract A rotating means in the form of a power operated tool rotates an elongated spiral member relative to a tubular serrated cutting member. The spiral member has a sharp tapered outer end which extends beyond the cutting edge of the cutting member. The spiral member penetrates into the area of the fowl adjacent the vent thereof and produces a reaction force to urge such area of the fowl into engagement with the cutting member to make a circular cut in the tissue surrounding the vent so as to disconnect the vent from the surrounding tissue and thereby remove the vent of the fowl.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 81 words
Apparatus for fowl vent removal comprising a tubular member having an annular cutting edge, reaction means comprising a flat strip coiled about the axis of said tubular member with the broad face of the strip substantially transverse to said axis, said reaction means comprising a portion lying within said tubular member and a portion extending outwardly beyond the cutting edge thereof, said outwardly extending portion terminating in a sharp tapered end, and means for rotating said reaction means about said axis.
Claim 2
Dependent Claim 81 words
Apparatus for fowl vent removal comprising a tubular member having an annular cutting edge, reaction means comprising a flat strip coiled about the axis of said tubular member with the broad face of the strip substantially transverse to said axis, said reaction means comprising a portion lying within said tubular member and a portion extending outwardly beyond the cutting edge thereof, said outwardly extending portion terminating in a sharp tapered end, and means for rotating said reaction means about said axis.
Claim 3
Dependent Claim 21 words
Apparatus as in claim 1 wherein said reaction means has a diameter only slightly less than that of said tubular member.
Claim 4
Dependent Claim 22 words
Apparatus as in claim 1 wherein said tubular member is fixedly mounted and remains stationary while said reaction means rotates within it.
Claim 5
Dependent Claim 11 words
Apparatus as in claim 1 wherein said cutting edge is separated.
Claim 6
Dependent Claim 14 words
Apparatus as in claim 1 wherein said reaction means is formed of spring steel.
Claim 7
Dependent Claim 25 words
Apparatus as in claim 1 wherein said reaction means is mounted on a spindle adapted to be received by the chuck of a rotary tool.
Claim 8
Dependent Claim 33 words
Apparatus as in claim 1 wherein the tapered end of said reacTion means is spaced outwardly from the axis of said tubular member and is positioned adjacent the cutting edge of that member.
