Title: Improvements in or relating to hack-saw machines
IPC: B23D49/00
Filed: 1937-11-30
Abstract: 506,489. Reciprocating saws. NEILL & CO. (SHEFFIELD), Ltd., J., SWAIN, G., and BOWER, W. L. Nov. 30, 1937, No. 34670/38. Divided out of 506,692. [Class 145 (ii)] In a hack-saw machine the pitch line of the teeth is inclined to the guide for the blade so that the teeth bite progressively more deeply during the working stroke, the guide being maintained stationary during at least the major part of the cutting stroke and fed forward in a single step once during each cycle by an irreversible feed mechanism. The saw 24, Figs. 1 and 3, is carried in a frame 16 which is reciprocated by the crank arm 51 and is guided by an arm 17 pivoted at one end to the frame of the machine, the other end being moved downwardly in steps by the feed mechanism. The saw is supported against bonding in its own plane by a non-reciprocating plate 18 against which it works, this plate being mounted in a frame 20 bolted to the arm 17 and having lugs 19 which bear against the sides of the saw. The thickness of the plate 20 is less than the width of the cut so that it can follow the saw without binding. The feed mechanism, shown also in Fig. 4, is operated at the end of each idle stroke by an arm 46 mounted on shaft 45 and oscillated by linkwork from a cam 50 on the driving shaft. The arm 54 on shaft 45 rotates the outer nut 40 in the casing at the end of the working stroke so as to raise the central screw 31 and lever 17, to which the screw is connected, during the idle return stroke of the saw. The nut 40 is returned by an adjustable spring. At the beginning of the working stroke, arm 54 similarly rotates collar 58 which acts through friction clutch discs 59 to rotate the long nut 80 and feed screw 31 and arm 17 downwards. Rotation of the long nut 80 backwards is prevented by a ratchet and pawl. Return of collar 58 is also effected by an adjustable spring. Screw 31 may be rotated by handle 35 and bevel gearing to raise and lower the lever 17 quickly, the handle and screw being normally locked. Specification 506,592 is referred to.

Title: Improvements in and relating to protective devices for oil filled electrical apparatus
IPC: H02H5/08
Filed: 1935-12-20
Abstract: 467,272. Indicating flow of liquids. SHEVLIN, J. T. (Siemens-Shuckertwerke Akt.- Ges.) Dec. 20, 1935, No. 35376. [Class 69 (i)] [Also in Group XXXVII] In a control float, which may be located in the pipe connection between the tank of a liquid-immersed electrical apparatus and its conservator, the influence of the liquid on those surfaces disposed substantially parallel to the direction of flow is substantially eliminated either by making such surfaces negligible, or by the employment of an elliptic float having its minor axis in the direction of flow, or by arranging one or more screens in the vicinity of the float so as to screen the surfaces. In this way, the action of the float is rendered independent of the liquid-viscosity, and of viscositychanges due to temperature variation. In the application referred to, the float operates a mercury switch or other means to disconnect the apparatus if a pressure-surge is set up in the liquid by an electrical fault in the apparatus. The screen may be attached to the float or, as shown in Fig. 5, screens 20, 21 may be located away from the float, which is pivoted at 4 and may contain the mercury switch 40. Alternatively, the switch may be arranged at the pivot of the float. The operation of the float may be adjusted to meet the required conditions, either by means of adjustable weights or control springs, or by varying the pivot points or by iris diaphragms or funnels for restricting the cross-section of pipe 2. The screens may be constituted by pivoted dampers which may themselves operate switches and be adjustable and may be subject to the fluid flow. In Fig. 19, the plate 86 serves as a screen for the liquidlevel float 84 and itself responds to velocity of flow, the two being mounted on a common member 87 which is pivoted at 88 and carries the pivot 85 of plate 86 and the mercury switch 95. A plate 102 is adjustably mounted in the inlet pipe to prevent the level in the housing from falling too low and so, in certain conditions, producing undesired operations by the float 84.
