Title: Spindle drive for a multiple spindle automatic lathe
IPC: B23Q5/14
Filed: 1964-08-04
Abstract: 1,025,506. Multi-spindle automatic lathe. WERKZEUGMASCHINENFABRIK GILDEMEISTER & COMP. A.G. Aug. 4, 1964 [July 24, 1963], No. 30904/64. Heading B3T. [Also in Division F2] The work spindles 7 of a multi-spindle automatic lathe can be driven at the same speed by a motor 1, or at least one of the spindles can be driven at a different speed to the others by a motor 8. Spindles 7 are mounted on an indexable drum 6, and motor 1 drives the spindles through change wheels 2, a central shaft 3 and gear-wheel 4, 5. Each of the indexable spindles has a toothed coupling member 16, and a cone clutch member 39 is movable along the spindle to engage with another cone clutch member 31, by a roller 41 actuated by an hydraulic piston 43. Clutch member 31 has teeth 32 and is rotated by motor 8 through change wheels 9, 10, shaft 11, and a gear 33 connected to the shaft by an overruning clutch 34. Toothed coupling member 15 is rotated at a slightly higher speed than clutch member 31, by gears 12, 13 and a shaft 14 and the shaft, along with member 15 is moved axially by a lever 22 actuated by a hydraulic piston 44. In operation drum 6 is indexed to align a spindle 7 with shaft 14 and piston 43 is actuated. Cone clutch 31, 39 is engaged so that the spindle speed is synchronized with the speed of clutch member 31. Displacement of sleeve 38 disengages a multiple disc clutch 37, thus uncoupling drive 1. Members 15, 16 rotate in the disengaged condition at a low relative speed until piston 44 is actuated to thus move these members into engagement, and the spindle 7 is rotated. Gear 32 drives gear 33 to overrun clutch 34. In a modification continuously adjustable gearing replaces gears 9, 10, or motor 8 may be a continuously adjustable D.C. motor. In a further modification the coupling between members 15, 16 comprises a single toothed clutch, thus ensuring that the movement is transmitted at the correct angle from the gearing unit to the spindle.

Filed: 1950-12-19
Abstract: 703,080. Rolling. HUTTENWERK GEISWEID, AKT.-GES. Dec. 19, 1950 [April 14, 1949], No. 30910/50. Class 83 (4). [Also in Group XXX] A manipulator for a rolling mill which is movable parallel to the roll stands and is provided with a work gripping device movable perpendicular to the roll stands is characterized. in that said gripping device is mounted in a tubular guide. The manipulator comprises a platform F mounted on rollers . 5, and an arm 17 mounted on a shaft 18 carried by bearings 32. The lever has a guide rail 14 for a slidable plate 6 on which a guide tube 4 is hinged at 7. The guide tube has a clamping device comprising a clamping cheek 9 pivoted at 34 and a pin 35 which passes through the slot of a guide 10 pivoted to the plate 6 at 36. When the guide tube 4 reaches one end of its travel the guide 10 strikes a stop 31 on the arm 17 and the cheek 9 releases the material to be rolled. The guide tube 4 is reciprocated by a chain 11 connected to the plate 6 and which passes over chain wheels 12, 13 the. latter being mounted on the shaft 18 which is driven through gearing 22 from a motor 21. The guide tube is turned in the direction of the arrow G by means of a flexible shaft 29, and a cranked rod 15 which actuates a push rod 16 attached to the guide. The arm 17 is rocked by rods 19, 20 actuated by a shaft 26 driven from the gearing 22 which also drives the rollers 5. The manipulator is controlled by hand levers 30. In operation, the platform F and the arm 17 are arranged so that the rolled material enters the guide tube 4. After the material has left the rolls, the guide tube is moved away from the rolls by the chain driving means and the platform moved in front of the adjacent rolls during which movement the guide tube may be rotated and the arm 17 correctly positioned for feeding the material into the adjacent rolls. The movement of the guide tube away from the rolls may be effected by the pressure of the material in which case a free wheel is arranged in the guide tube drive. The guide tube is then moved towards the rolls and the guide 10 brings the clamping cheek 9 to bear on the material to enable it to be forcibly fed into the rolls. When the rolls grip the material the clamp is automatically removed.

As shown, portion 1 undergoes deformation, being progressively rolled inside out within portion 2, Fig. 2. Portion 1 may, in turn, be preceded on the left by a portion of smaller cross-section than itself, with provision of a further round stepped intermediate portion and reinforcing ring, (Fig. 5, not shown). This construction may be continued by a yet further portion, and repeated in "mirror image" fashion on the right to form a symmetrical structure (Fig. 4, not shown). Before the reinforcing ring 4 is applied the device may be fabricated by expanding part L2 of ordinary piping material by hydro-forming, length L2 being half of L1. Ring 4 is bevelled where it contacts portion 3 and is spot-welded in place. Deformation may be facilitated, and the compressive force needed for it may be controlled, by providing axially-extending apertures in portion 1. The rigidity of portion 2 may be increased by providing it with an axially-extending projection, integral or otherwise.  The load is constant during deformation. The tubular body may be aluminium or mild steel, and the reinforcing ring 4, mild steel.

Abstract: 1,237,046. Coating confectionery. K. SCHAPER, R. SCHUENEMANN, E. SCHAPER and H. SCHAPER [trading as SCHAPER & BRUMMER]. 19 June, 1969 [21 June, 1968], No. 31195/69. Heading A2A. [Also in Division B2] Discrete articles, e.g. candies, pills, lozenges, dragees and the like, are coated by apparatus which includes a vessel 1 adapted to contain a plurality of the articles, a container 2 adapted to contain a supply of liquid coating 4 and having its interior communicating with the interior of the vessel 1, applicator means, e.g. a rotating brush 3, in the container for transferring quantities of the liquid coating into the vessel 1 for coating the articles, and control means for progressively increasing the quantities of liquid coating transferred during successive periods of time in correspondence with the increasing surface areas of the articles resulting from the application of the coating. Control may be effected either by progressively changing the setting of a timer (18, Figs. 2 and 3, not shown) through a motor driven gearing connected to the setting knob of the timer, so that successive periods of operation of the rotating brush 3, which are controlled by the timer, are of progressively longer duration or shorter intervals occur between them, or by progressively increasing the level of the coating liquid in the container 2. The latter is effected by the apparatus of Fig. 4 which replaces the conventional float 12 for controlling a solenoid valve 10 to maintain a desired liquid level. Instead, a probe 22 is used which is progressively raised by a screw- and-nut mechanism 30, 23 driven by a motor 28 which is operated either continuously or through a timer. The nut may also be rotated manually through a handwheel 24. In operation, the probe completes a circuit through wires 31 to the solenoid valve 10, to cause it to close, whenever the liquid level reaches the lower end of the probe.

[Class 106 (i).] Adding and subtracting apparatus ; statistical apparatus.-In apparatus for setting values upon registering or calculating mechanism, either the windings of a coil are energized in succession by the displacement of a non-polarized iron core, the field being thus progressively advanced in accordance with the values to be set, or a number of windings corresponding to the said value may be energized simultaneously. If a key, e.g. 7b, is depressed, a circuit is completed from the rail 8 through springs 2b, 2a to the solenoid 1a and thence through a contact plate 4a and core 5 to a spring-controlled bar 6. The core moves until it makes contact with a plate 4b, the second solenoid 1b then becoming energized and the movement of the core continuing until it reaches the centre of the second spool, the circuit through the first coil having been broken. The core then stops after having moved a distance corresponding to two units. In a modification, the circuit arrangements are such that the spools traversed by the core remain energized, the core then moving to the centre of the resultant field. Instead of keys 7a .., pins co-operating with perforated cards may be used. The Specification as open to inspection under Sect. 91 (3) (a) also states that electromagnets may replace the solenoids, the core then taking the form of a cylinder rolling past the polar surfaces. This subject-matter does not appear in the Specification as accepted.
