Patent GB-191210275-A (GB)
Title: Improvements in and connected with Systems and Apparatus for Range Finding and Automatic Sighting and Gun Laying.
Inventor: ANDERSEN FRIDTJOV
Filed: 1912-04-30
Granted: 1913-04-30
Abstract: 10,275. Andersen, F. April 30. Mountings.-Relates to automatic sighting and gun-laying systems of the kind comprising one or more observation stations, a central station having bars corresponding in number and disposition to the guns and observation points, and synchronously running motors or shafts controlled by contact devices operated by the sighting - apparatus at the observation stations. According to the invention, all the bars at the central station are pivoted together at a common point, and each bar is capable of sliding and rotating upon a fixed pivot, the relative dispositions of the fixed pivots being that of the guns and observation stations. Synchronously-running motors at the observation stations, central station, and guns are arranged so as to produce at the central station the movements of the observation apparatus, and to train and elevate the guns in accordance with the rotational and sliding movements imparted to the gun-representing bars at the central station by the movements of the other bars. If only one observation station is used, it is provided with a range-finder, and the adjustment of the range-finder causes, through the synchronous devices, a sliding movement of the corresponding bar at the central station proportional to the range. The latter arrangement is illustrated diagrammatically in Fig. 7. A and B represent the guns, C the observation station, and D<1> its range finder; E represents the central station and Z the target. At the central station, two bars a. b are pivoted to a nut z adapted to be traversed along a bar c by a screw d<1>. The bars a, b are slidable and rotatable upon pivots f, g, and the bar c is rotatable upon a pivot It. The positions of the pivots f, g, h, represent the relative positions of the guns A, B and the station C. Synchronously-running motors, represented by the connexions H, M, Q, m, h, combined with electro-magnetic clutches, cause rotation of the sighting-device C to be exactly reproduced as a rotation of the bar c about the pivot h, while other motors represented by I<1>, N<1>, R<1>, n<1>, i<1> effect the rotation of the screw d' in accordance with the adjustment of the rangefinder D<1>. The nut z is thus caused to assume a position relatively to the points f, g, h, corresponding to that of the target Z relatively to the points A, B, C. The bars a, b are thus displaced, and other synchronous devices f, k, 0, K, F, and g, l, P, L, G, cause the guns to be trained into the parallel directions. Other synchronous devices (not shown) elevate the guns in accordance with the distances between the pivots f, g and the point Z. The guns A, B are thus automatically layed upon the target Z. If the target is visible at the central station, the station C is dispensed with, and the bar c becomes the observation bar carrying the rangefinder.

Title: Improvements in or relating to Friction Clutches.
Inventor: PRICE SIDNEY LEOPOLD
IPC: F16D43/10
Filed: 1912-06-06
Granted: 1913-04-03
Abstract: 13,362. Price, S. L. June 6. Clutches, friction.-In centrifugally-operated friction clutches particularly applicable for driving dynamos at constant speed, the centrifugal members are pivoted to the driven shaft or part carried thereby and are placed between the friction members. Centrifugal parts g, Fig. 1, are pivoted to a driven shaft a on which slides the driven cone b, pressed against a cone e on the driving-pulley d by a spring f. The parts g may take various forms, and may be pivoted to a disk on the shaft. On excessive speed, the cone c is disengaged. Weights g, Fig. 6, may be connected by links to a disk m on the shaft a and to the clutch cone b. A ratchet clutch o, p may be interposed between the cone b and the shaft a, or within the driving - member. With this form, when the clutch is used for driving a dynamo for charging accumulators, if the speed of the driving-part d falls, the dynamo becomes a motor driven by the accumulator, and the shaft a speeds up and over-runs the cone b so that the parts g disengage the clutch. The clutches may be combined with retracting devices of the kind described in Specification 13,555/11. An extension of the driving-member may form a casing.

Abstract: 2189. Fortescue, A. J. Jan. 27. Driving-mechanism, special application of to windmill gearing. The length of the stroke of the pitman rod is increased as the windforce increases by means of a sliding member 27, the position of which along the rocking arm 19 is determined by a subsidiary windwheel driving a drum on or off which is wound a cord attached to a weight or spring as the wind force varies. The arm 19 is rocked by the rod 15 from the chain-andsprocket gear 17 driven by the main wheel, and carries an auxiliary wheel geared to a screw 24 through bevel or other suitable gearing. The spindle 30 of this wheel has fixed on it a guide-reel 31 on which is wound a rope or chain 32 attached to a weight 34 or to a spring so that as the cord is wound on the force required gradually increases until the wheel comes to rest and when the wind force decreases the cord is unwound. The screw 24 moves a nut 25 on the slide 27 along the arm 19 and so determines the position of the pivot point of the lower end of the link 28 according to the wind-force. The link 28 may be linked to the pitman 36 by a rocking lever 29. or directly, in which case the pitman is guided vertically in fixed guides. 2544. Aktiebolaget Ljungstr÷ms Angturbin.
