Abstract: 897,898. Hand-tool handles. RECKNAGEL, A. Oct. 27, 1958, No. 34357/58. Class 61 [Also in Group XIV] . Handle end caps 22, 23 are connected to sleeves rotatably mounted on the handle shanks of hair curling tongs so as to rotate therewith. As shown in Fig. 5 the sleeve consists of an inner metal tube 14 to which a plastic covering 16 is welded, the tube being retained on the shank 8 by a plate 18 screwed to the end of the shank and the plastic end cap welded to the plastic covering 16. In a modification, Fig. 6, the end cap is brass and is held by the resilience of slotted ends 25 of a metal tube 24 retained on the shank by an inner cap 21 soldered to the shank. Rotatable or fixed washers 12, 13 and plastic covers 10, 11 are provided, the shanks being flattened in the pivot region and haircurling legs, consisting of a round leg 2 and a shell 1, being formed as extensions of the shanks or welded thereto. In modifications the round leg is formed of tubular metal and is closed at the outer end by welding or as a rotatable sleeve. The outer surface of the sleeve may be knurled, ribbed &c. and the sleeve formed by independently rotatable annulae. U.S.A. Specification 1,622 834 is referred to. 897,908. Grinding. MIDWEST SUPPLY & MFG. CO. March 24, 1960, No. 10494/60. Class 60. A machine for finishing flat stock and the like includes a frame, a rotatable abrasive or like work finishing member mounted on the frame, means for driving the finishing member, a backing roll having a mount supporting the same on the frame for rotation on an axis parallel to that of the finishing member, the mount being pivoted on the frame to permit rocking of the backing roll in a plane containing the axes of the finishing member and the backing roll thereby automatically to maintain the axes in parallelism, co-acting feed-in and co-acting feed-out rollers arranged respectively to advance stock for finishing between the member and backing roll and to draw the stock away from the member and roll, means for positively driving the rollers, and means for positively driving the backing roll at a linear speed substantially less than that of the finishing member, whereby to exert controlling restraint on a piece of stock advanced between the member and backing roll. An endless abrasive or like finishing belt 15 is trained about an upper idler roll (not shown) and a lower drive roll 14 on a shaft driver, through belts 19, by a motor 16 on a base separate from the rest of the machine. The belt travels at up to 5,000 feet per minute. A motor 22 adjustable on the machine frame drives, through variable speed transmission, a power shaft 25 which drives through worms and worm wheels a set of four shafts 34 and a second set of four shafts 35. The shafts 34 drive, through universal couplings 38, four feed-in pinch rolls 36 and the shafts 35 drive, through universal couplings 38, four feed-out pinch rolls 37. The power shaft 25 has at each end of the machine shaft couplings 39 whereby corresponding power shafts of other similar machines may be coupled and driven together thus to operate a series of machines in tandem, the machines having belts 15 of different finishing quality or driven at different speeds. A backing roll 41 is driven, through belt or chain 57, from the shaft of one of the pinch rolls 36. The roll 41 is carried by a frame 43 carried by arms 44, 44 horizontally pivoted or trunnions 47 of a yoke 46 having a pivot trunnion 48 rotatably received in a fixed bearing member 49. depending from the machine frame. The position of the yoke 46 and associated elements is adjustable by a hand wheel 53. To sustain the roll 41 the frame 43 has an adjustable plate 60 cooperating with a roller 61 on a pivoted bellcrank 62, 64 connected to the plunger 66 of an air cylinder 67 having a control unit 71. Upward movement of the frame 43 and roll 41 is limited by an adjustable stop 75.
