Title: Improvements in starting systems for internal combustion engines and the like
IPC: F02N15/06
Filed: 1920-01-17
Abstract: 138,076. Dayton Engineering Laboratories Co., (Assignees of Chryst, W. A.). Oct. 23, 1918, [Convention date]. Turning-gear.-In an electric starting system comprising a dynamo-electric machine having motor and generator windings, the generator armature and field are utilized to produce an initial rotation which results in the disconnexion of the machine from the engine and its subsequent connexion with the motor armature and field in the circuit. In the form shown, a machine 32 having motor and generator windings 33, 35 is normally driven as a dynamo through a screwthreaded member 61 slidable on the armature shaft 31 and engaging an internally threaded member 60 on an engine-driven shaft 26. At starting, the machine 32 is given a slow initial rotation by supplying current through brushes 39, 40 to the generator winding 35, and the threaded member 61 is automatically unscrewed from the member 60 and by means of levers 70, 75 and a link 74 moves gearing 51, 54 into engagement with a pinion 50 on the motor shaft and the toothed flywheel 25. Current is then supplied to the motor winding and the engine is turned through the gearing 50, 51, 54. The gear ring 51 is carried by an over-running clutch to enable the engine to over-run the motor when it starts under its own power. The circuit arrangements are shown in Fig. 3. Starting is initiated by means of a hand switch 101 closing an ignition circuit from a battery 80 and conductor 82 to the primary winding 109 of an induction coil, a timer 110, and a rheostat 91. The switch 101 has a cam portion 105 which engages a slotted member 84 and closes a switch 83 in the circuit 87 leading to the generator winding 35 and the shunt field winding 38 of the motor. From the winding 35, the current passes to earth through switch contacts 46, 47, the contact 46 being mounted on the carrier 45 to one of the motor brushes 44, which is normally held away from the commutator 34 by a hook 78 on the link 74. When the automatic disconnexion of the members 60, 61 moves the gearing 51, 54 into mesh with the gears 50, 25, the link 74 releases the brush-holder 45, and a spring engages the brush 44 with the commutator and opens the switch 46, 47. The current to the winding 35 is thus cut off, and the machine can be run as a high-speed motor by depressing a pedal 131 acting on a brush 41, when current is supplied through a series field coil 37 to the motor winding 33. A lamp circuit is shown at 121.

Class 83(3). A combined turning, boring, drilling, tapping and milling machine comprises two upright columns 1, 2, Fig. 1, supporting a beam 5 which is adjustable angularly about a trunnion 11 and has slideways 6 for a universal headstock 9, and a tool-driving spindle (not shown), in a vertical plane in the headstock and transverse to the ways 6. A cylindrical, flat, curved or tapered surface may be produced on work supported on a table that can be rotated, by the feeding motor or by a further motor, at the cutting speed for turning operations and fed along ways 25, 26. The tool may be arranged horizontally or in any other position by holders 36 adjustable to vary the inclination of the tool. Profile milling may be effected by rotating the table 30 or traversing it on the ways 25, 26. The headstock 9 may be fed along slideways 8 on a slide 7 by a motor located beneath a hood 35 on the headstock, and the slide moved along the ways 6, as by a motor 34 driving a feed-nut (not shown), on a screw 33. An arcuate rack 15 on the column 2 concentric with the trunnion 11 facilitates angular adjustment of the beam 5 by engagement with a worm carried by the arm, in a housing 16, and driven from a key 20 through bevel gears. The beam is clamped, after adjustment, by bolts 12, 23, the heads of which engage at least one arcuate slot 13, 14, 24 in each column and concentric with the trunnion 11, and the column 2 may be taller than the column 1. Instead of supporting the columns on blocks 4 replaceable to vary the height of the trunnion, the latter may be carried by a slide 65, Fig. 6, adjustable on the column by a screw 59 rotatable in synchronism with another on the other column and arranged to adjust the height of the rack 15. In a further modification, Fig. 7, in which the screws need not be rotated in synchronism and arcuate clamping slots 55 are provided in the trunnion slide only, the unpivoted end of the beam 72 is supported in a guide 68 pivotally-mounted on the slide 67. As an alternative to mounting the worktable on ways 25, 26, it may have no linear feed and the columns be mounted to slide.

Filed: 1971-01-13
Abstract: 1334734 D.C. arc welding apparatus ESAB Ltd 13 Jan 1971 [14 Jan 1970] 1689/71 Heading H2H D.C. arc welding apparatus comprises a source 1 supplying a consumable electrode 7 and a workpiece 8 via an inductance 4 in series with an inductive winding of a relay switch 5, a shunt branch being connected in parallel with the inductance 4 containing a half wave rectifier 11 in series with an adjustable resistance 12, a second adjustable resistance 13 being connected via a multiposition switch 14, across the rectifier 11. In operation with switch 14 in position III as shown, the electrode 7 is advanced into contact with the workpiece 8 to establish a short circuit and cause current to rise in the inductor 4, no current flowing in the branch owing to the reverse bias applied on rectifier 11. Upon melting of the electrode tip and subsequent are conditions occurring, the current in the inductance 4 drops sharply causing a back E.M.F. to forward bias the rectifier 11 and cause a current to flow in resistance 12 dissipating a substantial portion of the energy stored in the inductance 4. The cycle is repeated with a subsequent shortcircuit period, the inductive winding 5 of the relay being energized by the first short circuit period, a delay being introduced such that the contact 5a is not opened until after preferably two arc periods. In a modification, Fig. 3 (not shown), an S.C.R. (18) is used and caused to conduct during arc periods by a back E.M.F. of the inductance (15) and by a gating pulse at the start of an arc period conducted through a branch comprising a resistor (20), rectifier (21.) and capacitor (22), the time constant of the gating branch and its capacitance being adapted such that the potential developed across the capacitor (22) after preferably two periods, renders further gating pulses insufficient to trigger the S.C.R. (18).
