Doffing - arrangements; thread-severing arrangements; spindle and lifting rails. - In spinning, twisting, and like machines, more particularly those of the flyer type, two bars 1 are arranged and adapted to engage within bobbin carriers 2 and to be moved by a horizontal rack bar 8 to remove the full bobbins and replace them by empty bobbins. During spinning the bar 1 to receive the full bobbins is supported by the spindle rail 5, as shown in Fig. 1, so that when the spindle, rail is lowered after completion of the set it is received in a recess in the rack bar, as shown in Fig. 2, which is then advanced so that the bar 1 enters the bobbin carriers 2, which are of bifurcated construction as shown, and carries them with the full bobbins beyond dead spindles 6. The other bar 1, with the empty bobbins mounted thereon, is then raised by the spindles 6 beyond the rack bar and lowered again so that it passes a hinged member 11 on the rack bar and is then seated thereon. The dead spindles 6 and the lifter rail 7 are lowered, the rack bar 3 being withdrawn so that the parts are in the position shown in Fig. 4. and are then raised simultaneously so as to support the full and empty bobbins and thereby to allow further withdrawal of the rack bar 3 to a position wherein the bar 1 which supported the empty bobbins is received in the recess of the rack bar when the lifter rail 7 is lowered. The rack bar is still further withdrawn so that when the spindle rail 5 is raised to its normal operative position the bar 1 is also carried thereby into the position shown in Fig. 1. During these operations the spindles are locked by a transverse bars 17 carried horizontally by a movable member 16. The spindle rail 5 is supported by spindles 18, Fig. 7, carrying arms 22 connected by chains to a differential pulley 24 loose on a shaft 25 and is balanced by a weight 28; it may be raised and lowered by a pinion 29 on a shaft 15 and a rack, or the pulley 24 may be fast on the shaft 25 and operated by suitable gearing.

Title: Improvements in or relating to fountain pens
IPC: B43K5/02
Filed: 1949-11-16
Abstract: 666,830. Reservoir pens. GEHA-WERKE GES. Nov. 16, 1949 [June 13, 1949], No. 29370/49. Class 146 (iii). A fountain pen comprises a main ink chamber and a communicating reserve ink chamber disposed adjacent the nib in front of the main ink chamber, and a manually operated valve, which after the supply of ink in the main ink chamber has been exhausted is adapted, when opened, to connect the reserve ink chamber with an ink duct in the feed bar, such that the contents of the reserve ink chamber flow under substantially atmospheric pressure directly to the ink duct. The reserve ink chamber a is filled with ink from the main ink chamber d through holes c formed in the cover b. A piston f normally closes a flow aperture g which connects the chamber a with an ink duct i in the feed bar. During the filling operation of the ink chambers d and a, effected by a piston k, ink is drawn into the duct i, through bores provided in the piston f and through a passage m into the chamber d. The fountain pen body enclosing the ink chamber d may be of transparent material, so that the level of ink therein may be observed. When the ink level is lowered to the level of the cover b the reserve ink chamber a is connected to the duct i by moving the piston k downwards. A control rod h secured to the piston carries the piston f downwardly, thus opening the aperture g and making ink in the chamber a available for use. In a modification, the body and nib section are moulded in one piece while the chamber a is provided with a conical aperture normally closed by a tube having holes at its upper end for the supply of ink from the chamber d to the ink duct i. The supply of ink in the ink chamber a is made available in this case by lowering the tube by downward movement of a piston. In a further modification, the flow aperture from a reserve ink chamber is closed by a flexible tubular slide valve which may be pushed upwardly to open the aperture by a slide member and downwardly to close the aperture by the piston used for filling the main ink chamber.
