Abstract
Abstract Apparatus for removing the bones from poultry comprising a conveyor means, a series of vertically mounted rollers on either side of said conveyor, and a set of horizontally mounted rollers mounted above the conveyor so that all said rollers form a tunnel with the conveyor to receive the birds. Some of the vertical rollers have cutting means associated with them to sever legs, wings and flesh from the carcass with the aid of grooves in some of the earlier vertical rollers. A driver or preliminary conveyor and cutter means may be provided, e.g., for larger birds, to strip off the wings and legs after which the stripped carcass is fed to the main part of the apparatus whose own wing and leg cutters then run idle. The preliminary and main conveyors may be continuous or separate.

Claim 1
Independent Claim
233 words
Apparatus for removing the bones from poultry, comprising a base conveyor to receive the poultry thereon and cause it to travel from an infeed end to an outfeed end, two rows of vertically mounted rollers, one at each side of said conveyor, a plurality of said rollers proceeding inwardly from said infeed end being peripherally grooved at two axially separated locations, a row of horizontally mounted rollers arranged above said conveyor to press down on the incoming poultry, cutter means on at least two laterally opposed ones of said vertically mounted rollers, wheels having curved cutting flutes arranged on at least two other laterally opposed ones of said vertical rollers, said wheels being rotatable in a direction opposite to that of the other vertically mounted rollers, deflecting means consisting of selected ones of said vertically mounted rollers, two hinged systems comprising selected groups of said vertically mounted rollers at said outfeed end with said rollers being mounted on support members, said hinged systems forming a pair of inwardly tapering walls to enclose the poultry carcass minus its legs and wings, said hinged systems also incorporating a plurality of cutters arranged in vertical lines with each of said cutters arranged obliquely to said vertical line, hoppers positioned to receive bones from the wings and legs and the flesh respectively, and a hopper at the outfeed end of the apparatus to receive the stripped carcass.

Claim 3
Dependent Claim
50 words
Apparatus according to claim 1, wherein some of said vertically mounted rollers at said infeed end are mounted to define an inwardly tapering path, said rollers defining said tapering path, and said rollers forming part of said hinged systems being rotatable faster than the remainder of said vertically mounted rollers.
Claim 4
Dependent Claim
32 words
Apparatus according to claim 2, comprising further, motor means and means for transmitting rotary movements to said vertically mounted rollers, said two means being mounted adjacent the upper parts of said rollers.
Claim 5
Dependent Claim
99 words
Apparatus according to claim 1, comprising also a preliminary conveyor, means for moving said preliminary conveyor, chain means mounted above said preliminary conveyor, said chain having grip means, means for moving said chain means substantially at the same speed as said preliminary conveyor, two oblique deflectors being resiliently lowerable on either side of a bird on said preliminary conveyor, said deflectors incorporating revolving cutters to cut off the legs and wings respectively of said bird, transverse conveyor means and longitudinal conveyor means movable in the opposite direction to said preliminary conveyor to receive the severed legs and wings respectively.
Claim 6
Dependent Claim
60 words
Apparatus according to claim 4, wherein said revolving cutters have teeth provided with cutting edges, the said cutting edges for severing the poultry legs being of a rounded shape, and said cutting edges for severing the poultry wings forming an acute angle to their cutting wheel, and said teeth being tilted in the direction in which their cutters are rotatable.
Claim 7
Dependent Claim
28 words
Apparatus according to claim 4, wherein said oblique deflectors incorporate rounded portions to touch the poultry and prevent the cutters penetrating into the flesh on the carcass thereof.
Claim 8
Dependent Claim
43 words
Apparatus according to claim 6, wherein said rounded portions are formed by horizontal rollers situated substantially higher than the level of the cutting edges of the cutters at a distance of about one quarter to one third of the diameter of said cutters.
