May 7, 1931, No. 13578. Convention date, Nov. 26, 1930. [Class 106 (ii).] Comprises a machine for testing toothed gears in a running test characterized by the fact that the heads on which the gears to be tested are mounted have together three rectilinear adjustments and one angular adjustment, two of the rectilinear adjustments being at right-angles to each other. The base 30 is formed on the upper face with ways 31, 32 extending at right-angles to one another and also in different horizontal planes. Mounted on the ways 31 is a slide 34 which may be adjusted by a hand-wheel 36 through bevel gear 39, 40, screw 41 and nut 43. The slide may be clamped in any adjusted position by a handle 49 operating a bolt passing through the guide flange and threading into the slide 34. The slide has a pair of arcuate T-slots 55, 56 having a common centre x and carries a swinging base 58 in an opening in which is fastened a sleeve 60. Bolts 62, 63 serve to secure the base 58 in adjusted position. The base 58 carries on guides 67 the driven bead 65 which may be moved from a shaft 68 through bevel gear 69, 70 and a screw 71, and clamped by a bolt 77. The driven spindle 80 is mounted in antifriction bearings 81, 82 and is provided with a brake drum 85. The hinged brake shoes are applied by a hand lever acting through toothed sectors and a cam. The drive spindle 120 is journalled in antifriction bearings 121, 122. The drive head 124 slides vertically on ways 131 on a column 130 by actuating a screw 132 and may be clamped by a bolt 138. The column 130 itself is slid on the ways 32 by rotating a screw shaft 140 and can be clamped by a bolt 146. In assembling the parts initially it is necessary to line up the spindle 80 with the bearing 60 so that the axis of the spindle intersects the axis x and provision is made for this adjustment. In operation, the gears to be tested are secured to the spindles 120, 80, and are rotated one driving the other. The spindle 120 is driven through a belt 162 from a motor 160 mounted on a base swinging on a pivot and which is locked by a spring bolt adapted to be released when a handle is applied to the adjusting screw. In chucking or dechucking gears the spindles 80, 120 must be held. The former can be held by the brake, while the latter is held by forcing a pin 180 into one of a series of holes in the face of the pulley 163 by moving the handle 184. In order to test long shank gears or cluster gears, an outboard support 190 is provided which slides into guides secured to the drive head 124 and the support slidably carries a tail-stick 195 carrying a centre. The various adjustments allow for a variety of gears of different sizes to be tested such as spur gears, helical gears, worm gears, internal gears, bevel. and hypoid gears.

Abstract: 127,768. Jones, D. E. W. Aug. 21, 1918. Windows and the like, cleaning.-Comprises a construction of apparatus for cleaning windows, glass screens, and the planes or wings of aircraft, of the general type in which a bar carrying a wiper slides in guides on the framing and is operated by cords or the like. In the present construction, bolts m, Fig. 2, mounted at the ends of the wiper bar, pass through slots in the window frame and carry rollers l running in the slots. Pairs of rollers o, running on the inner face of the frame adjacent to the slots, are flanged at p to engage the slots and prevent lateral movement of the bar, and also serve to adjust the pressure of the bar against the window, when the thumbscrews q are manipulated. Cords e pass from the ends of the bar over pulleys at the top of the slots and are joined together by a suitable handgrip. Pairs of hooks r secure the thumb-screws in the adjusted position. In a modified construction, Fig. 5, T-pieces s are secured to the window frame. The rollers l run in slots in the projecting arms of the T-pieces, while the rollers o engage the outer surfaces of the arms. Fig. 6 shows a slotted attachment t for windows having iron frames, when it is inconvenient to make slots in the material of the frame. The bar is raised by pulling the cords and returns by gravity, but the return may be assisted by weights or springs. The bar may move horizontally across the window instead of vertically, and may be formed in separately-operated sections. Fig. 7 shows the apparatus adapted for cleaning the wings of aircraft. Wiper bars a, mounted as previously described, are connected at each end to a double system of cords leading to a common winding- drum w. By operating the drum in opposite directions the bars are drawn inwards and outwards along the wings.
