Title: Chain-stitch sewing machine
IPC: D05B73/12
Filed: 1921-04-27
Abstract: 183,586. Fairweather, W., (Singer Manufacturing Co.). April 27, 1921. Sewing-machines; thread end-holders and thread cutters; governing needle thread.-A sewing-machine of the kind producing groups of stitches as employed in button-attaching, tacking, &c., and of the type employing a rotary looper for a single-thread chain-stitch is provided with a thread nipper on the supply side of the needle and with a second thread nipper weaker than the first arranged beneath the work rest which is inactive while the needle performs the first reciprocation of a set, the free end of the thread being at the same time drawn beneath the work by the looper, but is then moved automatically to retain the free end during the second reciprocation of the needle. The nipperarm 23, shown as mounted below the work-plate 19 of a machine for button-attaching provided with means for jogging the work-support, is actuated by a link 38 connected to an arm 37 mounted on a rock-shaft 33 rocked by a doublearmed lever 34 engaging cam-plates 29 on the periphery of the cam-wheel 16. The nipper is in contact with an adjustable spring 26 and nips the thread against the plate at the side of the needle-throat. The cam-plates are so arranged that the arm 36 of the lever 34 is in contact with the part e of a cam-plate at the commencement of a group of stitches and as the needle descends the arm is moved by the cam to ensure the retention out of action of the nipper until the needle has made the first stitch. The loose end of thread is at the same time drawn through the work by the looper. As the needle is half-way down on its second stroke the arm 36 rides down the surface d of the cam and the arm 35 rides up the surface b. The nipper is moved into nipping position and yieldingly retains the thread until the commencement of the third stroke, whereupon the arm 35 rides down the surface a and the arm 36 up the surface c and the nipper is moved out of action and withheld during the rest of the stitch-forming cycle. A thread-nipper 18, opened by a cam 18' on the needle-shaft s, and stronger than the nipper 23 nips the thread from just before the entry of the needle into the work on the down-stroke until it has lifted three quarters of its distance above the work on the up-stroke. The effect is that in the second needlestroke the looper draws sufficient thread from the free end for part of the loop against the tension of the nipper 23, but obtains the remainder from the thread supply after the release of the nipper 18 on the up-stroke. A thread-cutter 51 pivoted to the work plate and operated by the overthrow action of the stop mechanism cuts the last loop of a series close to the work.

Abstract: 699,371. Machine tool details. SIEMENSSCHUCKERTWERKE AKT.-GES. May 30, 1951 [Nov. 7, 1950], No. 12797/51. Class 83 (iii). [Also in Group XXIV] Control apparatus for the main and feed drives of machine tools with a member adjustable for different machine operations (e.g. a tool turret) comprises selectively operable control means for each of the drives, a control device having a movable member, switch means responsive to the different positions of the adjustable member, a jack panel having two groups of selectively closable contact pairs, and electrical connections whereby selectively correlated speeds of the main and feed drives may be obtained for each position of the adjustable member. As applied to a turret lathe, twelve speed changes are provided for the main drive 13, Fig. 1, and four speed changes (not shown) for the feed drive. The main drive motor 10 is a two-speed pole-change motor and the further speed changes for the main drive are obtained from gearing and magnetic clutches I-V. A disc 14, Fig. 1, is coupled to move with the turret and carries switches E<SP>1</SP>-E<SP>6</SP>, representing the turret stations, which co-operate with a fixed cam N to close the switches in turn. The switches are wired to a jack panel, Fig. 3, divided into groups G 1 , G 2 , G 3  for main drive, feed drive, and pole-change of the motor, respectively. The required contact path on the panel is previously set up for the speed and feed required at each limit position, by introducing plugs 15, 18, 20, etc., or throwing over jack switches at these points. This pre-setting operation may be assisted by the use of templates. Current paths are thus established to the magnetic clutches and pole-switches, a single impulse from the switches such as E 1  being transferred by the jack panel to the three variable groups.

IPC: H03F1/54
Filed: 1941-10-03
Abstract: 552,438. Thermionic valve circuits. PHILIPS LAMPS, Ltd. (Naamlooze Vennootschap Philips' Gloeilampenfabrieken). Oct. 3, 1941, No. 12825. [Class 40 (v)] A variation in the operating conditions or circuit constants of an oscillator or amplifier is arranged to cause replacement by a reserve unit, the arrangement being such that each of the oscillators or amplifiers controls the maintenance of its own operation. The Figure shows an oscillator 1 and a second oscillator 11 the latter being normally biased to cut-off. A relay 20 is provided to change over the load at contacts 16 if the oscillator 1 is inoperative through relay 22 while an alarm A is operated by auxiliary relay contacts and an urgent alarm B if both oscillators fail. In this condition relay 21 closes contacts 9, 91, to reduce the grid bias so that at least one oscillator delivers energy to the load on the re-establishment of the supply voltage. The circuit constants of the oscillators are so chosen that oscillation is only started if contacts 9 or 91 are closed but are maintained with these contacts open. In an amplifier for a signal containing a constant component, control is effected by rectifying part of the output otherwise an auxiliary oscillation outside the signal frequency range is fed to the input through a series connected transformer and the rectified output reduces the bias on the amplifier from cut-off to the normal operating voltage.
