[Also in Group XXIV] An electric fan comprises oscillatable louvres at one end of the fan casing and impeller blades at the other end, the impeller and the oscillating mechanism being driven by a motor situated between the impeller and the louvres. The fan casing comprises two parts 6, 7, Figs. 2, 11 and 13, of sheet metal or, as shown, of plastics. Wire mesh guards 8, 9 are provided, the guard 8 being held in place by an inner cylinder 13 of sheet metal or plastics. The driving motor 4 is supported by two pairs of horizontal bars 35, 36 connected at their outer ends to plates 38, 39 respectively. Each plate 38 or 39 fits into pockets 86, 87 on the casing parts 6, 7, and a flanged member 92 fits over the pockets. The casing is supported on a base-plate 70 having two pairs of arms 71, 72 and 73, 74 connected to caps 75. Each cap 75 carries a fastener 85 which is inserted through the aligned holes 94, 88, 89 and 39<SP>1</SP>, after which the head 98 of the fastener is turned to actuate a cam 99 which compresses a rubber sleeve 100 so that it bulges as shown in Fig. 11 to clamp the assembly together. The sleeves 100 also act as pivots about which the casing can be tilted. Louvres 15, Figs. 8, 9 and 11, of sheet metal or plastics, are pivoted in depressions 21 in a plate 17 and in depressions 24 in leaf springs 22 riveted to a plate 16. The plates 16, 17, which are of sheet-metal or plastics, are attached, as by screws 80, to diametrically opposite sides of the casing part 7. The louvres 15 are coupled by a wire 28 having loops which spring on to grooved pins 26, and are oscillated through another wire 55 by a wheel 47. Wheel 47 is driven by the motor 4 by friction gearing comprising a wheel 41, Figs. 14, 15 and 16, engaging the motor shaft 31<SP>11</SP> and connected through a sleeve 125 to a wheel 42 which engages the wheel 47. The sleeve 125 is journalled on a shaft 401 carried by a pivoted arm 43. Wheel 47 is rotatably mounted on a rod 49 having a threaded portion screwed into a bracket 50.

Abstract: 748,726. Screwing-up caps and bungs. CALIFORNIA RESEARCH CORPORATION. Oct. 14, 1953 [Oct. 31, 1952], No. 28339/53. Class 83 (3). [Also in Groups XVII and XXIII] A device for inserting a screw cap or bung 100 into an opening 113 and for screwing it up in correct alignment comprises means 27 for holding the bung 100, drivable means 93, and means 10 connecting it with the holder such that the holding means cannot rotate relatively to the drivable means but can move laterally and/or tilt. The bung 100 is held against a rubber ring 53 on the holder 27 by suction produced in a central bore in the device. As the device is lowered, a lip 29 engages the rim 112 of the bung-opening in a drum 110; further motion presses the bung 100 towards the opening against the pressure of a spring 42; and the bung is then tightened as it is rotated through the shaft 10 and hexagonal connections 14, 75. The hexagonal connections each consist of a hexagonal socket and a hexagonal engaging-member having spherical sides to allow " floating ". The bung-holder may therefore move laterally or angularly to allow for misalignment between the tool and drum opening. The bungholder is formed with two recesses to engage lugs 104 on the bung to rotate it positively. A modified holder for a cap 120, Fig. 12, has a diametrical recess to engage the bar 124 and the sealing ring 53 is arranged to contact the inside of the bore 123 in the cap. In the latter case, the lower rim of the tool engages the drum itself and not the rim of the opening.

Abstract: 2,12,853. Marks, E. C. R., (Gould & Eberhardt). Stept. 11, 1922. Gear-cutting; milling-cutters.- In a process for producing a helicoidal groove of predetermined contour a hob is fed axially along the blank, and the teeth of the hob are so arranged that each cutting-edge removes substantially the same amount of material as the immediately preceding cutting-edge. Figs. 1 and 2 show the arrangement of the teeth on the hob, the teeth T<1> - - T<15> acting as roughing-teeth and the teeth F<16> - - F<19>, finishing-teeth of unbroken contour. The roughing-teeth are serrated as shown in order to break up the chip. The Specification also describes the method of designing the hob to avoid interference in cutting, the path of interference being obtained graphically and the interfering-portions removed by re-cutting the hob-helix using a lead somewhat' longer than the theoretical lead. Fig. 3 shows the hob in cutting relation with the workpiece, the hob being advanced as the cutting proceeds in a direction parallel to the work axis. In order to facilitate the mounting of the hob, in the machine, the side walls W, W<1> are accurately located in relation to the helix and the key seat Z is preferably located in definite relation to one of the finishing- teeth. On account of its short length the hob is stated to be particularly suitable for cutting a worm on a shaft within a short distance of a shoulder.
