Abstract
764,138. Narcotizing plant for bacon hogs. WERNBERG, N. E., and KRAGH, C. J. Jan. 17, 1955, No. 1378/55. Class 81(1) In a plant for narcotizing bacon hogs in which the hogs are carried into a pit containing a gas such as carbon dioxide, whereby they are narcotized directly before being stabbed, there is provided a number of movable hog boxes arranged successively in a closed circuit and moving compulsorily along a path of such form that the point where a box is located when the hog is removed it is located beside the place where the hogs enter the boxes. As shown in Figs. 1 and 2 the hogs are driven along a passage 7 through a door 8 of sector shaped crosssection and pivotable about a vertical hinge 10 and carrying. an operating arm 11 which when turned into the position indicated by a dotted line 11<SP>1</SP> admits the hog to the conveyer 12. Transverse fences consisting of vertical uprights 15 along the conveyer form boxes in which the hogs are carried into a covered pit 16 filled with a narcotizing gas such as carbon dioxide which is fed to the pit through pipings 64 leading from a storage tank 65 through a control box with cocks to the interior of the pit. The narcotized hog 27 lying in its box is carried up from the pit to a delivery point where an operator 30 attaches the hind legs of the hog 28 to a chain 29 which is then fastened to an inclined chain conveyer 31 on which the hog is hoisted on to a sliding rail 32 to be immediately stabbed in its neck so that the animal remains unconscious. In the plant shown in Fig. 5 the hog boxes 44 are mounted on two endless chains 45, one in front of and one behind the boxes, each of which chains passes around a pair of chain wheels 46, 47 moving stepwise in the direction of an arrow 48. When a hog 49 has entered a box 50 the box is lowered into a pit 51 filled with carbon dioxide and the hog is, in its narcotized state, carried up again to a delivery point 52 where an operator swings the one side wall 53 of the box down into its horizontal position, fastening the hind legs of the hog 54 to a chain and attaching same to an inclined conveyer 55 which carries the hog on to a sliding rail 56. In the plant shown in Fig. 6 the hog moves from the supply passage 57 along a bridge 58 displaceable in its longitudinal direction into a box 59 having a removable end wall 63 and spaced steel side members 60 on either side, the box being mounted as a gondola in a pair of arms 61 which arms may revolve stepwise moving 90 degrees at the time when the bridge 58 has been withdrawn free of the gondola. When the gondola is in the position denoted by 62 the narcotized hog is removed through the rear side wall the hog is attached to an inclining conveyer 55.
