Abstract: 1,053,698. Skinning machine. WOLVERINE SHOE & TANNING CORPORATION. Aug. 16, 1965 [Aug. 24, 1964], No. 35016/65. Heading A2U. A machine for skinning hog sides comprises a rotatably driven drum 12, gripping means 14 extending along the periphery of the drum and a skinning blade assembly 40 mounted on arms 42, 44 such that it can be raised or lowered by cams 58. The blade assembly 40 comprises blade 72 held in holder 70 which is removably supported at its ends in support members 84, 86 mounted at the ends of the drum 12, a stop 90 at each end of the drum and removably held in members 84, 86 by tapered pin 102, manually operated cams means 142 acting on holder 70 to engage the surface 80 thereof against surface 96 of the stop 90, and manually operated eccentric cam means 110 which actuates rods 106 extending through holder 70 to push blade 72 against surface 92 of stop 90 and thus properly align the blade 72. The surface 92 and the edge of blade 72 are in the same plane as the rotational axis of the drum 12. Steam jacket 84 heats the blade 72. The rollers 28 are adjustably mounted. In use the hog sides supplied by conveyer 20 have their leading edges gripped by means 14 and as the drum 12 is rotated the skin is separated from the meat by blade 72, the meat being passed to a conveyer 160 (Fig. 2, not shown) and the skin being dropped from the drum 12 into a container.

Abstract: 1,054,071. Thermographic copying apparatus. MINNESOTA MINING & MANUFACTURING CO. Aug.6, 1963 [Aug.8, 1962], No.31001/63. Heading G2A. A machine intended for thermographic copying is built up between side plates 11, 12 Fig.1, (not shown), and comprises a cylindrical shroud 18, at the bottom of which is the printing zone, between irradiation source 53 and roller 40. At each end of the machine, just outside the shroud, are two rings 25, supported by rollers 21, 22, 23, 24 Fig. 2, (not shown) for rotation about a horizontal axis. Attached to each ring is a gear 26, having teeth on its internal periphery which mesh with a spur gear 27. The rings are interconnected by a rigid draw bar 30, to which is attached the forward end of a flexible spring clamp member 32. The rearward end of member 32 is deformed to act as a retaining clip inside a channel member 34. The original or master sheet is fed to the machine from a shelf 65 having a movable front section 66. Just above this is a compressible pad 62 on a half-core member 61, mounted on a rotatable shaft 60. As this shaft is turned, a cam 67 Fig. 2, (not shown) causes the movable shelf portion to be lowered to such a position that it guides the master sheet, now being pushed along the shelf by the pad portion 62, so that its leading edge enters channel member 34, where it is gripped firmly by clip 33. A driving means connected to spur gear 27 now comes into operation, causing the rings 25 Fig. 2, (not shown) to rotate anticlockwise. As member 32 moves with the rings, the master sheet is bent back sharply over the channel member 34, and is smoothed down as it passes under a springy plate 58 just before the printing section. It then comes into contact with a copy sheet fed forward by a roller 70 from a supply on plate 73. The two sheets then pass in contact through the printing zone, between rubber rollers 50, 51, and metal roller 40, the latter being momentarily lowered to allow the sheets to pass. Roller 51 has a slightly larger diameter than roller 50 so that, when rotating at the same speed, a slight tension is imparted to the master sheet. An intense radiation source 53 is surrounded by an elliptical reflector 52. After leaving the exposure zone, the master sheet in clamp 32 continues on its circular path while the copy sheet passes on under roller 81 to a receiving tray 84.

An axial flow multi-stage gas turbine has an outer casing divided into upper and lower half portions 21a, 21b respectively along a horizontal axial plane P. Stationary shroud rings 34, Fig. 2, are mounted inwardly of the outer casing between adjacent stator blade shroud rings 29 by means of grooved retainer rings 36. Each shroud ring 34 is divided into two halves 34a, 34b, Fig. 3, of slightly less than 180‹ angular extent so that the facing ends 53a, 53b are spaced apart. In order to seal the space 54 between the facing ends whilst permitting thermal expansion of the ring halves, upper and lower arcuate sealing blocks 55a, 55b are mounted in the space by dowels 59. The plane faces 56 of the blocks abut in the dividing plane P and resilient sealing strips 64a, 64b are mounted in grooves in the respective facing surfaces of the blocks and ring halves. The space between the diametrically opposite ends of the ring halves is sealed in the same manner. Spaces 65a, 65b permit the axial passage of coolant air supplied to the interior of the outer casing through a pipe 50, plates 68a, 68b being provided to throttle the coolant flow. Each stator blade shroud ring 29 is also divided into upper and lower halves (29a, 29b), Fig. 5 (not shown) of less than 180‹ but of greater angular extent than the halves 34a, 34b, and supported by the retainer rings 36. The space between the facing ends (70a, 70b) of the halves (29a, 29b) is sealed by a pair of abutting sealing blocks (75) screwed (at 72) to the adjacent retainer rings 36 and having sealing flanges (77). Each retainer ring 36 is also divided into segments of less than 180‹ in a manner similar to that already described, Fig. 4 (not shown). The shroud rings 29, 34 are locked against circumferential movement by bolts 44, 46, respectively, engaging lugs on the rings. The mounting and sealing construction of the rings is applicable also to axial flow compressors.
