Filed: 1930-02-10
Abstract: 354,331. Spring motors. MYERS, M., 21, Darnley Road, Mare Street, Hackney, London. Feb. 10, 1930, No. 4452. [Class 10.] In a spring motor, particularly for gramophones, two or more springs are arranged so that they can be wound up successively in an intermittent manner and may afterwards unwind simultaneously to deliver the stored power. The outer ends of the springs a, a<1> are secured to a barrel b which is anchored to a pillar w. The inner end of the upper spring a is secured to a sleeve c and the inner end of the lower spring a<1> is secured to an arbor c<1> coaxial with the sleeve c. A thin plate 18 separates the springs. Winding-up is effected by a lever f, Fig. 2, pivoted at 11 and having a toothed sector 21 engaging gears 20, 25. One-way clutches comprising pawl-and-ratchet gears are provided and the toothed gears are so arranged that when the lever f is rocked in the direction of the arrow A it winds up the spring a through the gear train 21, 20 and the clutch 19, d, but does not wind the second spring a<1>. When the lever f is rocked in the opposite direction it winds up the second spring a<1> through the gear train 21, 25, 24, 22 and the clutch 23, d<1>, but does not wind the first spring a. In the end position of the lever f its sector 21 is out of gear with the gears 20, 25 and then the stored power may be used to drive the spindle u through gearing t when the brake of the speed governor 4 is released. The springs unwind simultaneously and drive through ratchet clutches k, k<1>, gears m, ml and an intermediate shaft o. The arm f may extend through a slot in the side of the gramophone cabinet, or it may be cranked and extend through a curved slot in the top wall, or it may be engaged by a pin movable in a straight slot in the top wall.

Abstract: 525,318. Moulding chocolate &c. LOESCH, M. Feb. 17, 1939, No. 5353. [Class 87 (ii)] In apparatus for emptying moulds such as chocolate moulds travelling one after the other in a series, each open filled mould 1 is covered with a plate 8, such plate is retained in position, the mould is turned through 180 degrees and is tapped, whereupon the plate 8 supporting the moulded articles is released and descends under gravity, and the mould and the coveringplatewith the moulded articles thereon then continue separate ways. Tapping the mould and releasing of the cover plate may be simultaneous. The moulds are carried by conveyer chains 2 to positions at which plates 8 are supplied and at which the moulds pass into the inverting device. After emptying the moulds, the chocolates, upon the cover plates, are removed on a conveyer 6. The inverting device comprises guides 9, Fig. 6, on swing arms 10, the mould being held elastically by springs 12 and grippers 11. The inverting-device is initially engaged by fixed guides 23 which enter between rolls 14 and the arms 10 and draw back slides 13 against the action of springs 15 so that lever mechanism 16, 19 is operated to maintain holding-members 20 in a raised position. As the arms 10 move up with the mould and disengage from the guides 23, the slides 13 move inward and the members 20 are moved down to the position shown in Fig. 6 to hold the plate 8. When the mould is inverted, a tapping-device is operated ; this device is provided with side guides which enter between the rolls 14 and the arms 10 to move back the slides 13 and so operate the members 20 to release the plates 8 which thereupon descend with the moulded articles on to the conveyer 6. The guides move the rolls 14 back so far that pawls 21 engage the arms 10 and maintain the members 20 raised until the empty mould is swung back on to the conveyer 2 and the pawls are engaged and released by the guides 23.
