Abstract: 178,444. Kruse, F. April 12, 1922. Sausages.-In a sausage-twisting machine alternate sections of the filled casing are rotated in opposite directions by belts which co-operate with stationary and movable formers which engage the casing at the junctions of adjacent sausages, and a vertically moving carrier raises the sausages to facilitate removal. The casing is placed between belts 21, 21<a>, which are interspaced with the stationary formers 25, and hinged formers 29 are pressed on the casing at the points of contact with the formers 25, the rotation being stopped when the casing reaches the bottom of the spaces 26 in the formers 25. The casing is then lifted by strips 48 which are attached to a lifting-frame interconnected with cam gear 59 and the arms 24 whereby the belts are moved apart to facilitate removal. The formers 25 are spaced apart by the length of a sausage, and the spaces 26 are V-shaped. In Fig. 4 three formers 25 are shown, the outer spaces being filled by belts 21 and one of the inner spaces by a belt 21<a>, the belts 21, 21<a> being trained over lower rollers 19, 19<a> respectively and upper rollers 20. The rollers 19, 19<a> have grooves 43, which engage projections 44 on the belts to obviate slipping. The outer rollers 19 are interconnected by pinions 16 and idlers 18, and are keyed to the shafts 15, some of which are rotated by a shaft 35, having a handle 42, by worm gearing 40, 41. The inner rollers 19<a> are keyed to sleeves 33, revolubly mounted on the shafts 15, which sleeves are secured to pinions 34 interconnected by idlers. The pinions 34 are driven by a shaft 38 driven by worm gearing 36, 37 from the shaft 35. The hinged formers 29 pass into spaces 28 between the formers 25 and plates 27. End formers 45 of V-section are pivoted on the end members 46 of the removing frame which comprises bars 46 connected at their ends by rods 47, the lifting-strips 48 being secured to the bars 47 and spaced thereon by sleeves 49. The strips 48 slide in the spaces 28 and, when the casing, is being twisted, are below the spaces 26. The removing frame is lifted into the position shown in Fig. 5 by arms 55 which engage the underside of the spacing- sleeves 49, and are moved angularly by shafts 50, 51, one of which is provided with a handle, the shafts being interconnected by shafts 54 and bevel-gearing 53. The rotation of the shafts 50, 51 raises rods 57 by cams 59, the arms 24 of the pivoted beltsupporting arms 23 being operated to move the belts into the dotted position, Fig. 6. The lifting-strips 48 are then in the dotted position, Fig. 6, and the end formers 45, which are held vertically when in operation by stationary rods 63 over which the formers 45 slide, fall inwardly, Fig. 5, to facilitate removal. The rods 57 are restrained longitudinally by collars 58, and move in elongated holes 61 in the frame members 10. A smoke stick 71 having an upstanding metal strip 72 is placed on the removing frame and engages the central twists of the sausages on removal. In a modification, Fig. 12, both sides of the belts 88 contact with the casing, and the former plate 96 moves with the removing frame. The belts are held against the casing by scissorslike members 87, which are opened on the descent of the former plates 96 by pins 100. Rollers 89 are provided at the upper ends of the members 87, and the lower ends are connected by springs 90, which move apart the faces of adjacent belts when the pins 100 rise with the removing frames. The hinged formers 97 are provided with recesses 99. Hook-shaped end formers 101 are used which have V-shaped portions in which the casing is compressed during twisting, the former 101 being held in the operative position by bars 105 on which they rest during removal, Fig. 19. The removing-frame is lifted, as shown in Fig. 19, bv levers 94. In another modification, Fig. 16, the upper rollers are carried on pivoted members 109, which are horizontal in the operative position and vertical during removal, the movement being effected by bars 113, 107 which are operated by cams on the shafts 95. Fig. 20 shows a further modification, having an endless belt 120 passing over rollers 121, 122, 123.
