Title: Improvements in hoists
IPC: B66D1/16
Filed: 1932-05-03
Abstract: 401,307. Winding and paying-out apparatus &c. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(Ingersoll-Rand Co. ; 15, Exchange Place, Jersey City, New Jersey, U.S.A.) May 3, 1932, No. 12775. [Class 78 (v).] In a self-sustaining winding gear, a clamp member, movable to engage friction means with the hoisting drum, is rotatable with said drum and connected thereto by a spiral spring which maintains the clamp member in a non-operative position while the drum is moving in one direction and permits the clamp member to press the friction means into engagement with the drum when the latter moves in the reverse direction. As shown, the drum 90, driven through epicyclic gearing by a shaft 26 coupled to the shaft 16 of an electric motor, is provided with a flange 106 having a threaded portion 112 connected by a spiral spring 136 to a clamp member 124 having a threaded hub 125. When a load is being raised, the clutch facings 128 of a friction clutch 126 hold the member 124 against rotation so that it moves away from the drum against the tension of the spring 136. The spring winds up until its tension overcomes the friction of the clutch facings and permits the drum to rotate the member 124, the clutch facings being held against rotation by a hand-controlled brake band 62 engaging a flange 126a. When the driving motor is stopped and the drum starts to revolve in a reverse direction, the tension of the spring 136 is relaxed so that the clutch facings cause relative rotation between the drum and the member 124 and the latter forces the clutch facings against the flange 106.

Title: Improvements in trigonometrical calculating machines
IPC: G06G3/06
Filed: 1917-09-08
Abstract: 166,173. Taylor, A., and Gray, P. W. Sept. 8, 1917. Logarithmic calculators.-Relates to apparatus for solving the range problem involved in obtaining the range from a gun station G, Fig. 6, to an invisible target (indirect-fire) B by means of angular measurements from two observation stations A, C at a known distance apart, by means of a repeated application of the law of sines in a plane triangle, the invention consisting primarily in deriving from the movements of manually-set members movements proportional to their logarithms, and in then adding and subtracting these values. The observed angles BAC and ACB are set manually by means of handles moving over graduated circles, or they may be set upon indicating-circles by electric transmission from the observing stations, in which case the operator sets the handles to agree with the indications, agreement being ensured by means of repeat pointers upon the indicating-circles. Bevelwheels 29 and 30, Fig. 1, are rotated by one of the handles 5, of which one wheel 30 actuates, through differential gearing, a cam 37, Fig. 3, cut to the logarithmic curve log. sin. ABC so as to position a cam arm 38. The other bevelwheel 29 operates through another differential gear a cam 54 cut to a logarithmic curve that positions a cam arm 55, and thence through a third differential gear influences a pointer 59 indicating the gun range GB. Rotation of the handle 5 also drives a shaft 16 and thereby a cam 113 cut to log. sin. BAC; in addition it transmits the value of this angle to a cam 122 that automatically adds the constant angle CAG, thereby imposing a value proportional to log. sin. BAG upon a differential gear 57, 58. In similar manner the second handle (not shown) introduces values proportional to the angle ACB and rotates a cam cut to a curve of log. sin. ACB, and thence through a differential gear 82, 83, meshing also with a'sun-wheel 39 deriving movement from the handle 5, influences a pointer 85 moving over dial 60 to indicate values corresponding to a logarithmic co-efficient of a range AB. The angle ACB is also superposed upon the angle BAC to obtain the supplement of ABG. Thence by a shaft 93, Fig. 4, worm and wheel 97, 98, and shaft 99 with worm 100 meshing with a wheel 101 bearing a cam 102 cut to a logarithmic curvecorresponding to possible values of the gun-laying angle AGB, this angle is indicated.
