Title: Improvements relating to electric spot welding machines
IPC: B23K11/31
Filed: 1932-02-23
Abstract: 394,758. Welding-machines. DORRAT, J. A., 9, Kenwood Road, Stretford, Manchester, and ASSOCIATED ELECTRICAL INDUSTRIES, Ltd., Crown House, Aldwych, London. Feb. 23,1932, No. 5436. [Class 83 (iv).] A multiple spot-welding machine, particularly for use in the manufacture of meter box parts, is provided with electrodes 1, 2, 3, Fig. 3, which can be moved simultaneously to operative position towards a fixed set of electrodes 1a, 2a, 3a and retained there during the welding operation by a rotary cam 4 which is actuated by a continuously operated electric motor 29 through a magnetic clutch 30. Engagement of the clutch and the motor is effected initially by means of a push-button 44, Fig. 1, or other manual or pedal device, and thereafter maintained automatically by an electric switch 39-41, which is closed by the action of a cam 37, until the main cam 4 has rotated through 345‹. The welding circuit is established and maintained during rotation of the main cam through 270‹ by the action of a cam 38 on contacts 40, 42, the latter energizing a coil 46 adapted to close the main contact 45 of a welding transformer 35. When the welding circuit is broken, the cam 4 exerts an increased force on the movable electrodes to upset the weld and then permits their withdrawal to inoperative position under the action of springs, whereupon contact of a braking device 43 with the retracted clutch 30 brings the cam to rest after one complete revolution. The duration of the weld can be adjusted by providing a rheostat 48 to vary the speed of the motor or by adjustment of the ratio of gearing between a constant speed motor and the cam shaft. The welding current mav be varied by adjusting the voltage tap of the welding current transformer to accommodate different thicknesses of work. The movable electrodes may be subjected to the same predetermined pressure by interposing spring-loaded plungers 19, 20, 21, Fig. 3, between the electrodes and the cam 4. In a modification, Fig. 5 (not shown), a combined multiple electrode is moved towards a set of fixed electrodes by similar means.

Abstract: 765,272. Binoculars. LEITZ GES., E'. Feb. 24, 1955 [May 17, 1954], No. 5557/55. Class 97(1) In a binocular optical instrument one eyepiece is connected to the focusing knob through a releasable clutch so that the other may be adjusted independently of it to compensate for the difference in focusing ability between the eyes of an observer. As shown, the drive between focusing knob 9 and lens 21 is interrupted on pressing the knob axially against the action of spring 8 to release the frictional coupling, through friction disc 22, between knob 9 and head 18 of shaft 16. Sleeve 5 is keyed for rotation with the spindle, of knob 9 but is prevented, by engagement with sleeve 2, from moving axially therewith. Screw 12 is prevented from rotating in sleeve 2 by the engagement of projection 12a in slot 2b so that on rotation of knob 9, the axial movement of. screw 12 is transmitted by arm 26 and sleeve 13 to lens 15. Shaft 16 is prevented from moving.axially by disc 17 engaging sleeve 2 and by cap 3, and its rotational movement displaces nut 19 and lens 21 therewith rectilinearly. Resilient washer 23 serves as a seal, and additional seals are provided between the cap 3 and the adjacent parts. The knob 9 may be provided with a transparent cover 24 and the head 18 of shaft 16 may have a scale graduated in dioptres. The recess in screw 12 for arm 26 is sectorshaped to enable tubes 1 and 1a to which the outer components of the objectives and the eyepieces may be sealed to pivot about sleeve 2. Components of the optical systems other than lenses 15 and 21, such as prisms, may be axially movable to effect the focusing. Specification 285,094 [Class 97(i)] is referred to.

Abstract: 224,781. Hurst, J., and Hurst, J. March 6, 1924. Mules.-In a mule for spinning waste or shoddy from condenser bobbins, in order to piece up a set of ends from a spent bobbin, the new ends are secured in a clip, spaced apart to the pitch of the roving guides in the mule, the bobbin is then placed in the mule creel, the clip is drawn forward to lay the new ends over a bracket alongside the old ends, and the whole of the pairs of ends are rubbed together by a bar with a yieldable face, which is reciprocated over the bracket. The clip comprises two parts 16, 17, Fig. 4, with interengaging holes 23 and pins 27, and hinged clips 28. End members 24 are secured by resilient strips 25 to provide spaces 26 which can engage the flanges of the bobbin and hold the clip on to it. The bobbin is mounted on standards at the rear of the mule, or on special wall brackets, or on brackets on the carriages used to transport the bobbins to the mule room. These brackets are provided with slots to accommodate the clip and a bar with guides of the requisite pitch. The ends are drawn from the bobbin over one part of the clip and through the guides. The other part of the clip is then secured in position and the whole clip is secured to the flanges of the bobbin. When the bobbin is in position in the mule creel the clip is drawn forward, laying the set of ends in the guides 19, Fig. 2, and the clip 16, 17 rests on the bracket 19<a> secured to the guide bar 19<b>. A piecing-rod 21 with handles 22 is then laid over the ends. The set of new ends is broken by moving the clip and the rod 21 is reciprocated to rub the ends together. The rod 21 is provided with a resilient piece of rope or rubber 32 held by a leather strip 33. The two parts of the clip may be hinged together, and the engaging faces may be V-shaped. To position the bobbin on the mule creel, so that the correct length of roving exists between the clip and the contact point Z, with the driving-drum 34, a graduated gauge is provided on the creel standard or a bent iron bracket may be secured to the creel standard, so shaped as to give the correct position when the clip is in contact with it.
