Abstract
Abstract The apparatus is used for trimming and cauterizing the beaks of fowl and utilizes a heated cutting and cauterizing blade with a cauterizing projection attached thereto so that the blade and the cauterizing element move together across the face of a beak holding means, thereby shearing off and cauterizing the end of the beak while the cauterizing projection passes between the upper and lower halves or mandible and maxilla of the beak. The beak holding means limits the portion of beak exposed to the blade by the size of an aperture through which the beak is protruded, the aperture being adjustable in size to accommodate different sized beaks, and adjustable sideways to permit alignment of the plane between the mandible and maxilla of the beak with the cauterizing projection.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
133 words
A beak trimming device comprising: a frame; a beak holding means mounted on said frame; a heated cutting blade operably mounted on said frame; a means to move said blade relative to said beak holding means in a cutting stroke; and at least one cauterizing projection attached to said blade and extending substantially normal thereto on the side thereof adjacent to said beak holding means, said cauterizing projection being conductively heated by said blade and disposed thereon in a position which is substantially aligned with the interface between the mandible and maxilla of a beak held in the beak holding means during the cutting stroke, whereby the cauterizing projection can sear a channel through the adjacent surfaces of the mandible and maxilla and cauterize these surfaces simultaneously with the trimming of the beak.
Claim 2
Dependent Claim
133 words
A beak trimming device comprising: a frame; a beak holding means mounted on said frame; a heated cutting blade operably mounted on said frame; a means to move said blade relative to said beak holding means in a cutting stroke; and at least one cauterizing projection attached to said blade and extending substantially normal thereto on the side thereof adjacent to said beak holding means, said cauterizing projection being conductively heated by said blade and disposed thereon in a position which is substantially aligned with the interface between the mandible and maxilla of a beak held in the beak holding means during the cutting stroke, whereby the cauterizing projection can sear a channel through the adjacent surfaces of the mandible and maxilla and cauterize these surfaces simultaneously with the trimming of the beak.
Claim 3
Dependent Claim
51 words
The structure of claim 1 wherein said beak holding means comprises a substantially planar structure generally parallel to the stroke of said heated blade, said structure having an aperture for the insertion of a beak, said aperture being open at the top to accomodate said cauterizing projection during the cutting stroke.
Claim 4
Dependent Claim
36 words
The structure of claim 2 wherein said aperture has a clearance slot at the bottom to further accommodate said cauterizing projection to insure complete contact between the cauterizing element and a beak held in said aperture.
Claim 5
Dependent Claim
25 words
The structure of claim 1 wherein said beak holding means has a beakreceiving aperture and including means to vary the effectie size of said aperture.
Claim 6
Dependent Claim
114 words
In a beak trimming machine having an operatively mounted cutting blade and a beak holding means in which the portion of a tapered beak exposed to said cutting blade is limited by the diameter of an aperture in the beak holding means through which the beak is inserted, an improved beak holding means comprising: an anchor plate with an aperture therein; a strike plate with an aperture therein; a fastening means whereby said strike plate is adjustably fastened on said anchor plate in face to face contact with the apertures partially aligned to produce an effective aperture whose size can be varied by a sliding adjustment of the strike plate on the anchor plate.
Claim 7
Dependent Claim
114 words
In a beak trimming machine having an operatively mounted cutting blade and a beak holding means in which the portion of a tapered beak exposed to said cutting blade is limited by the diameter of an aperture in the beak holding means through which the beak is inserted, an improved beak holding means comprising: an anchor plate with an aperture therein; a strike plate with an aperture therein; a fastening means whereby said strike plate is adjustably fastened on said anchor plate in face to face contact with the apertures partially aligned to produce an effective aperture whose size can be varied by a sliding adjustment of the strike plate on the anchor plate.
Claim 8
Dependent Claim
48 words
The structure in claim 5 wherein said anchor plate has a plurality of different sized apertures and said strike plate has a plurality of correspondinglY positioned and dimensioned apertures whereby a single adjustment of said strike plate can achieve a concomitant adjustment of a plurality of effective apertures.
Claim 9
Dependent Claim
67 words
The structure in claim 5 wherein said anchor plate is slightly resilient and said strike plate defines a shearing surface on one side thereof for said cutting blade, the portion of said strike plate first to meet said cutting blade during the shearing stroke having a lip curving away from said one side to insure proper cooperation between said strike plate and blade during the cutting stroke.
Claim 10
Dependent Claim
23 words
The structure in claim 5 wherein said strike plate has a gripping means engaging said anchor plate to prevent accidental sliding after adjustment.
