Abstract: 266,862. Smith, F.B. Jan. 15, 1926. Variably-applied weight apparatus.-In weighing-apparatus an arc-shaped counterpoise is attached by reverse flexible bands to a straight weigh-lever and has connected with it a second lever also attached by reverse flexible bands to an arc-shaped pivot, there being means for tensioning the bands in each case. The lever a, d, pivoted at b and having the load applied at c has the counter-poise e attached to it by flexible bands which are fastened to the counter-poise at f<1> and g<1> and after passing round the arc of the poise are attached to the lever at f and g respectively. The point g is on a member h which may be adjusted by a screw k relatively to the lever d to tension the bands. Pivoted by a reverse knife-edge at l to a vertical rod rigid with the poise e is a second lever m similarly attached by bands to a fixed pivot n. The arrangement is such that levers d and m are always parallel and the pointer o attached to the weigh lever moves equal amounts for equal increases of load. In modifications, (1) the arcs of members e and n are parallel, the member n not being fixed but being attached by a flexible link to a fixed member; (2) the weigh lever carries a fixed counterpoise and the load is applied to an underslung lever parallel to the weigh lever.

Title: Improvements in methods of welding chain links
IPC: B21L3/00
Filed: 1920-01-14
Abstract: 138,071. Eckermann, C. W. H. von. Jan. 18, 1919, [Convention date]. Welding.-In electrically buttwelding chain links, the ends of the links, which are cut perpendicularly to the plane of the links and preheated preferably by fuel heat, are first moved apart laterally, then moved endways so that the ends slightly overlap and are then pressed laterally during heating, so that the burned parts interpenetrate as shown in Fig. 3, removing the slag and being thus buttwelded together. The parts are pressed together until they are in alinement. The links may be pre-heated to a red heat in a furnace. In welding links of large size, they are dipped into deoxidizing substances such as charcoal, pit-coal, coke, or reducing gases or a mixture of fluor spar and ferro-manganese, ferro-silicon, powdered carbon or aluminium after preheating so as to prevent oxidation during the welding operation.

Abstract: 550,608. Stethoscopes. BRITISH THOMSON-HOUSTON CO., Ltd. Jan. 29, 1942, No. 1219. Convention date, Jan. 30, 1941. [Class 40 (iv)] [Also in Groups XX and VI] Apparatus capable of use for determining the source of periodic noises in machinery &c. comprises a tubular sound-communicating channel, a disc having a transparent section of good sound transmitting character and an opaque section of poor sound transmitting character, and means for rotating the disc so that the sections alternatively move across the channel and provide intermittent sound transmission through the tube and intermittent vision around it. Fig. 1 shows aligned tubes 12, 13 and stethoscope tubes 15 for conveying sounds to the ears of an observer from gears 10, 11 under examination. A disc 14 having a slot 21 is rotated between the tubes by a motor 16 provided with a speed controller 17 and tachometer 23. The slot 21 periodically permits vision of the gears and the simultaneous periodic transmission of sound from them. Examination may be effected on the gears in turn, and the period of the observations may be adjusted to be nearly equal to that of the gears ; the gear then appears to rotate slowly, and the noise to vary in intensity as the gear rotates, if the noise arises from that gear. The slot 21 may be of variable length, preferably by forming the disc 14 of two relatively-adjustable face-to-face members, and thin transparent membranes may be stretched on the outer surfaces over the slots to reduce noises due to air turbulence; an adjustable damper may be provided in the tube 13. The Specification as open to inspection under Sect. 91 describes also a modification, Fig. 3 (Cancelled), in which a machine 27 is observed by means of periodic flashes from a lamp 25 and by a microphone 28 in circuit with an amplifier 30 and earphones 29. The circuits for lamp and microphone are periodically completed by the closure of contacts by cams 26, 31 on the shaft of a motor 24 having a speed controller 33 and tachometer 32 ; the cams may be adjustable to positions slightly out of phase to accommodate unequal lag in the sound and lighting systems. The lamp and microphone may be adjustably mounted on a common handle. This subject-matter does not appear in the Specification as accepted.

Filed: 1921-01-10
Abstract: 157,371. Union Ges f³r Metallindustrie. March 19, 1917, [Convention date]. Back-pedalling brake and free-wheel arrangements.- In a coaster hub employing a screw-threaded driving- member for actuating driving and braking cones. the resilient frictional drag device for ensuring the necessary relative movement of the parts is, during driving, adapted to be disengaged owing to the relative movement of the brake cone with respect to the driving-cone and to the drag device. The driving-cone 2 is mounted upon the internally screw-threaded sleeve portion 1<a> of the brake cone 1 and is held thereon by a spring ring 5, relative rotation between the two cones being prevented by the engagement of projections 3 on the cone 2 with slots 4 in the cone 1. The slots 4 are also engaged by lugs 7 on a sleeve 6, which by its bent-out portions 11 bearing upon the brake member 9, constitutes the drag device: a compression spring 8 fixed at 10 to the cone 1 bears at its other end upon the lugs 7 and so tends to keep the parts 1, 9 in engagement. In driving, the parts 1<a>, 1, 6, 9 move to the right until the lugs 7 engage with the projections 3. The cone 2 is then moved into engagement with the hub, and at this stage further axial movement of the drag device is prevented. The parts 1<a>, 1, however, continue their movement to the right until the cone 1 engages with the cone 2, when these parts rotate together with the hub and the driving-member. The brake member 9 is then free between the drag device and the cone 1.
