Filed: 1927-08-23
Abstract: 276,664. British Thomson-Houston Co., Ltd., (Assignees of Chapman, V. J.). Aug. 30, 1926, [Convention date]. Fluid-pressure presses.-A pressure member for clamping the work in an automatic arc welding machine or for applying pressure to the electrodes of a resistance line welding machine is prevented, by movement of a brace for connecting the two abutments between which it acts, from being actuated until the brace is in operative position. The welding head 11 of an arc welding machine for welding the longitudinal seams of tanks is traversed by a motor on a track 7 over a pair of beams 5 mounted on frame members 1, 2 and carrying jaws 15 against which the work is pressed by a backing member 12 forced upwards by plungers 13 operated by distensible hose 14 supported on a beam 6 which is fixed at 16 to the frame. The other end of the beam is supported during operation by a latch bolt 17 which. is pivoted on a shaft 27 provided with a link 23 controlled by a spring 26 to hold the bolt both in its open and closed positions. The link is connected by links 24, 25 to a valve 22. Fluid pressure is supplied to the hose through a valve 18 and also communicates with the valve 22 through a by-pass 21. When the bolt is open the fluid is by-passed through the valve and so the pressure member 12 is rendered inoperative, but when the bolt is closed after insertion of the work the valve 22 is closed thereby and the fluid passes into the hose. A similar bolt 59, Fig. 3, together with links 60, 58, 57 and valves 56, 54, is used to control the pressure which passes through theflexible hose 52 to the upper roll electrode 36 of a resistance welding machine. The electrodes 36 are mounted on wheeled carriages traversed on the arms 31, 32 so as to weld work such as a tank 34 secured by lamps 35 to the arm 32. The carriages are connected by arms 47, 48 to the carriage of a motor 37, which through gearing 39 - - 42 is traversed along a fixed rack 38. Specification 275,197, [Class 39 (iii), Heating by electricity], is referred to. The Specification as open to inspection under Sect. 91 (3) (a) states that the invention is applicable to devices for applying pressure other than welding machines. This subject-matter does not appear in the Specification as accepted.

G., 68, Eltham Road, Lee, London. Aug. 7, 1931, No. 22404. [Class 40 (iv).] Separate circuits which are adapted to supply feed current and which normally provide a through metallic circuit for impulsing may be associated with any rank of selectors as is most convenient. The feed bridge is switched in in response to a backward signal when the connection has been completely set up or when an outgoing junction has been seized. If however outgoing repeaters are connected in the junctions, the feed circuits are associated only with the selectors of the rank which deal with local calls and with those which deal with both local and junction calls, provision being made whereby the feed bridge is not switched in on junction calls. The circuit shown may be placed before the pre-final selector and forms a part of the system described in Specification 378,585. The selectors are held by earth on the d wire over relay H. When the switching relay operates at the final selector, battery is applied to the c wire, and relay H energizes, connecting up release relay B and metering relay J. Line relay A energizes and ringing current is supplied over ring-trip relay F which operates on reply, followed by back-bridge relay D. Relays H, J fall back, the latter applying a metering impulse to the c wire. A preliminary continuous ringing current may be applied immediately the ringing circuit is completed by making relay H slow to release and connecting contact a3 over a front contact thereof to a suitable source, the back contact being connected to relay F.

In the arrangement of Fig. 1, a shaft 12, which may be the driver, carries splined torus discs 1 coacting with twin sets of non-planetary rollers 3 driving a middle double torus disc 2 connected by a splined drum to the driven shaft 17. The rollers 3 are journalled in carriers 18 supported by the rockers 4 in turn supported on pivots on a fixed duplex member 20, 21 which is externally supported. Load is equalized between the rollers of both sets by the rocker arms engaging helical cams 7, 8 of opposite hand, as described in Specification 392,589, these cams being splined on a freely floating through balancing sleeve 6. These cams are in the form of rings which carry or serve as the limiting stops and are axially movable between stop collars 11. Supposing the control spider 5 is set for low speed, the rockers 4 are tilted and the carriers 18 moved longitudinally of Fig. 2 so that the rollers precess, as described in Specification 254,341, [Class 80 (ii)], towards the extreme position of Figs. 1 and 4. A cross arm 18<a> on each carrier 18 then strikes the cam stop 7 or 8 so that these stops are thrust inwards towards one another of Fig. 1. The arrangement is such that this axial displacement of each cam ring tilts the rockers which engage it so that the rollers 3 precess away from that limiting position. Cross arms 18<b> provide for the high-speed limiting position. As applied to driving vehicles, the cam stops are preferably biassed to mid-position by springs to meet conditions incidental to coasting and braking by the engine.
