Title: Automatic stop mechanism
IPC: D03D51/00
Filed: 1952-02-01
Abstract: 734,007. Operating clutches; couplings. JUTE INDUSTRIES, Ltd., and PLENDERLEATH, J. S. Nov. 23, 1953 [Feb. 1, 1952], No. 2690/52. Class 80 (2). Normally-engaged clutch teeth 14 on a driving member 13, slidable under the control of an operating lever 16 pivoted at 19, and a driven member 12 are disengaged automatically upon the occurrence of defective working or overload of the driven machine which, through a cable or rod 39, causes a lever 33, pivoted at 34, to turn anticlockwise so that a roller 37, engaged in a slot 30 in a lever 27 pivoted at 28 on an extension 29 of the lever 16, moves to the bottom of the slot and in so doing turns the lever 27 clockwise to bring a roller 31 thereon into the path of chamfered projections 24 on the member 12, whereby the lever 16 is forced clockwise to disengage the clutch. When the defect has been remedied, a spring acting on the lever 33 turns it clockwise, so that the lever acts on a pin 26 to turn the lever 16 anticlockwise to reengage the clutch, the roller 37 riding up the slot 30 and so turning the lever 27 anticlockwise to bring the roller 31 out of the path of the projections 24. There is a lost-motion connection between the machine shaft 11 and the member 12, comprising a disc loose on shaft 11 and having a cross pin engaging between pairs of peripheral pins on the member 12 and on a member secured to the shaft 11, one of each pair of pins being engaged in any one of a number of peripheral holes so as to adjust the lost motion, and the disc being connected both to the member 12 and to the other member by torsion springs. The arrangement is such that, during drive, the torsion springs are wound up and there is a positive drive through the pins from member 12 to shaft 11, while when the clutch is disengaged the torsion springs cause the member 12 to turn backwards relative to the shaft 11 to take up the lost motion.

Abstract: 1418255 Vehicle window regulator FORD MOTOR CO Ltd 21 Jan 1974 [12 Feb 1973] 02831/74 Heading E2M A vehicle window regulating mechanism acts on two separately movable window sections (18, 19), Fig. 1 (not shown), to fully lower a ventilating section (18) before lowering a main section (19), and comprises a mounting plate 21 secured to a vehicle panel, a gear sector 23 rotatably mounted on the plate, a pair of regulator arms 26 and 27 each swingable about a common axis 24 on the mounting plate and respectively coupled to the sections (18) and (19), a drag link 42 pivotally connected to the sector 23, a pair of drive links 49 and 56 pivotally coupled to the drag link and the regulator arms 26 and 27, respectively, and a pair of cam plates 58, 59 each having a cam slot 66, 71 therein which receives a cam follower 69, 74 mounted on a respective drive link 49, 56. The sector 23 is rotated clockwise by means of a pinion and clutch assembly 25 to open the window sections. The configurations and dispositions of the slots 66, 71 and drive links 49, 56 are such that initial rotation of the sector causes the regulator arm 26 to swing and thus lower the ventilating section, but keeps the regulator arm 27, and therefore the main section 19, fixed. When the section 18 is fully lowered further rotation of the sector 23 causes the follower 74 to move along the slot portion 73 which causes the regulator arm 27 to swing and the main window section 19 to be lowered.

Abstract: 457,236. Automatic volume control; two-way transmission. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. Jan. 31, 1936, No. 2996. Convention date, Feb. 27, 1935. [Class 40 (iv)] [See also Group XL] Relates to amplitude filters analogous to frequency filters but comprising non-linear resistances so arranged that the transmission properties are determined by the amplitude instead of the frequency of the applied voltage ; and consists in employing inverse non- linear resistances in such a way that the characteristic impedance of the amplitude filter is constant. Thus the combined resistance Rp of a pair of dry-plate rectifiers G1, G2, in parallel, Fig. 1, gives a response curve A when plotted against the applied voltage U, while the combined resistance Rs, Fig. 2 (not shown), of the two rectifiers in series is inverse to Rp. If the rectifiers are biassed by means of oppositely directed batteries the curve A is broadened, Fig. 3 (not shown) ; and a similarly broadened inverse curve D, Fig. 4, can be obtained by connecting the rectifiers G1, G2, in series and arranging a bias battery Uo in conjunction with ordinary resistances W as shown. The non-linear resistances thus obtained are built up to form an amplitude filter of the lattice type, Fig. 5, or of the bridged-T type, Fig. 6 (not shown) ; and by the use of inverse resistances the characteristic impedance is rendered independent of amplitude while the transmission is of the high-pass or low-pass type ; currents of low amplitude or high amplitude, as the case may be, are suppressed. The inductance arms may be coupled or not, or may be replaced by resistance arms. Echo-suppressors. Instead of being derived from a battery the bias voltage may be derived from one path of a four-line telephone transmission system so as to act as an echo suppressor in the other path.

Abstract: 607,415. Wringers. SUMMERSCALES, W. H. G., HOLMES, W., and HOLGATE, B. R., (trading as SUMMERSCALES' SONS, W. & S.). Feb. 2, 1946, No. 3379. [Class 138((ii)] The detachable top bar 5 of a wring- ing machine carries the spring 6 for applying pressure to the upper roller 2 and is hooked or otherwise detachably secured at one end 10 to one side shoe 4, the other end being provided with a pivoted side member 12 having an abutment or projection 13 adapted to engage and traverse a pivoted locking cam 14 until a position is reached in which the abutment or projection passes the vertical or dead centre of the pivot 14* of the cam. In this position, spring loading is applied to the top roller. In order to release this pressure, it is necessary to depress towards the rollers either of two bars 7 which are pivoted on opposite sides of the top bar 5 and have depending aprons 9. This movement of the bar 7, which occurs against the action of springs 8, causes fingers 16 on the bar to depress projections 15 on the cam 14, whereby the latter turns on its pivot until the abutment 13 is freed and the member 12 and top bar 5 fly upward under the action of the spring 6. The upward movement of the bar 5 at this time is limited either by a shackle 19 which is secured to each end bearing 20 of the upper roller 2 and normally passes loosely over each end of the spring 6, or by abutments 18 on the member 12 engaging ridges 17 on the cam 14; in the latter case, a gap 17x is provided in the ridges 17 to permit the member 12 to be completely detached from the cam.
