Type-case machines; hammer impression arrangements.-A print hammer mechanism, for a printer having a horizontal type bar 11 consisting of a flexible sheet metal comb with a plurality of types mounted in the distal end of each tooth of the comb, comprises a plurality of hammers 12, each having an armature portion held in engagement with a magnet 13 by energization of a winding 48 thereon, against the action of a cantilever leaf spring 21, whose leaf 26 overlaps a portion 19 of the hammer to urge the hammer into printing position when the magnet is de-energized. After a hammer has been fired, the leaf 26 comes to rest against a stop bail 32 and the hammer is restored to its rest position by a return spring 14 whereby the portion 19 of the hammer is arrested by a stop finger 31 provided on the distal end of leaf 27. When all the hammers have been fired, a shaft 39 carrying cams 37, 38 engaging rollers 42, 44 of a spring mounting bail 22 and a hammer drive mechanism 15, respectively, is rotated through one revolution to thereby move the mounting bail 22 and stop bail 32, on the drive mechanism 15, in an arcuate path to reset the leaf spring 21, so that the leaves 26 engage the portions 19 of the hammers once more (Fig. 2, not shown), the resetting movement being completed when the stop bail reaches the position indicated in Fig. 1.

Abstract: 560,267. Winding cops. MACKIE & SONS, Ltd., J., and MACKIE, J. P. Oct. 30, 1942, No. 15310. [Class 120 (ii)] In a cop-winding machine the yarn is traversed over the tapered nose of the cop by a grooved roller which is driven by the drag of the yarn in the groove and which is mounted so that it can be retracted when required to facilitate starting of the winding or for piecing, and to be returned to its correct positions for winding purposes. As shown the roller is formed of two parts 16, 17 fitted together to provide the helical groove 18 and is rotatably mounted on a spigot 20 having a stub axle 22 mounted in a bracket 21 at the bottom of an arm 23 fixed to the machine frame. The axle 22 carries a hand-lever 26 by which it can be turned to retract the roller from the cop and the roller is held in its operative position by a spring-pressed plunger 29 mounted on the lever 26 and engaging a notch 28 in a sectorshaped flange 25 in the bracket 21 ; a stop 35 on the flange 25 supports the hand-lever 26 and roller in the retracted position. The cop may be formed between tapered rollers 10 and a buttress 15 and the roller may engage the cop to brake its rotation or the nose of the cop may be formed in a fixed conical cup having a slot for the yarn or for the grooved roller. The part 17 of the roller may be mounted on a reduced part of the part 16 and fixed thereon by a screw 36, the part 16 being fixed to a spindle journalled in spaced ball-bearings in the hollow interior of the spigot 20 which also forms a receptacle for lubricant and may have a thimble secured to the upper ball-bearing to ensure the supply of lubricant thereto.

Title: Improvements in and relating to means for drawing sheet glass especially with fourcault machines
IPC: G03B21/602
Filed: 1939-05-25
Abstract: 529,221. Electric heating. DEUTSCHE TAFELGLAS AKT.-GES. (DETAG.). May 25, 1939, No. 15532. Convention date, June 13, 1938. [Class 39 (iii)] [Also in Group XXIII] Relates to a method of maintaining the temperature of the molten glass, and also preventing devitrification, in an apparatus for drawing sheet glass, particularly of the Fourcault type, by passing a current of electricity between electrodes inserted in the glass. According to the invention, alternating current, preferably three-phase, is used and the top of at least one of the electrodes lies approximately vertically below the edge of the sheet at each end of the drawing-slot. The electrodes 13, 14 preferably are composed of Siemens-Martin steel of low carbon content in order to prevent discolouration of the glass, and they are inserted through the side walls of the drawing-chamber so that their tips are below the ends of the slot in the debiteuse 2, or below the edge of the sheet when any other device for holding the meniscus of the sheet in place is used. The electrodes are pointed to obtain a higher current density and to enable them to be pushed easily through the stiffer glass at the sides of the chamber. When three-phase current is used, a third electrode 25 may be inserted in any part of the glass, and it may be surrounded by a floating pan 16 to collect any scale that falls from the exposed part. Additional groups of associated electrodes 19, 20, 21 may be used in the parts of the glass where devitrification is likely to occur. Groups of three electrodes may be arranged, also, beneath the ends of the debiteuse 2.

Electrodynamic reinforcement of contact pressure under high-current conditions is provided by the looped parts 47. The arms 29 are recessed to receive a U-shaped plate 40 which fits over insulation 37 surrounding the rigid metallic core 35 of bar 33, and projections on each side of the recess pass through holes in a plate 39 and are riveted over to clamp the arm 29 to the bar 33. The handle 75 is carried on an inverted U-shaped bracket 59 pivoted at 61 and two springs 73 couple it to the junction of toggle links 63, 65 which are respectively pivoted at 71 and 69 to an arm 29 and a fixed frame plate 57.
