Title: Improvements relating to the piecing of yarns or ends in mules and other spinning, twisting and like machines
IPC: D01H3/26
Filed: 1921-03-22
Abstract: 184,829. Wilman, R. A. March 22, 1921. Mules; spinning and twisting machines.-In spinning, twisting, and like machines, means are provided for placing broken ends in contact with spindles, &c. The device is shown applied to a mule. The placer, Fig. 2, which may be of wire or of L-shaped sections 6 joined by brackets 10, and has thread-grooves 11, is carried by a sliding arm 7 which is operated by a shaft 9, lever 8, and spring- controlled lever 12 keyed to the shaft. The placer is released for operation when a segmental lever 23 keyed to the shaft 9 is freed by withdrawal of a catch 27 carried by the lever 26, which in turn is actuated by the movement of a spring-pressed rack 30 pivoted to the carriage. The rack 30 may be freed from the pawl 33 by a cranked hand-lever 37 engaging a bowl 39 on the pivoted arm 29 carrying the rack 30, or by a rod 41 operated by a lever 42 and a collar adjustably mounted on the faller stop rod and having an arm 47 engaging the pivoted rack. The first movement of the carriage releases the placer which moves towards the spindles 19 and places the threads in contact therewith; an adjustable stop 22 carried by the rod 14 fixed to the rod 7 limits the movement. The continued movement of the carriage restores the placer to the position adjacent to the guide and delivery roller by means of a bowl 50 on the arm 48, which engages a bellcrank lever 54 provided with an adjustable stop 54b adapted to engage the lever 51, and thereby operates the link 52, lever 53, and shaft 9 and restores the placer. A placer arm may be provided for each spindle or group of spindles.

Abstract: 792,782. Haymaking machines. MASCHINENFABRIK FAHR AKT.-GES. March 21, 1956 [April 2, 1955], No. 8802/56. Class 6(3). A tractor-drawn agricultural machine comprises a carrier frame 9 mounted upon lifting links 2, 3 carried by a tractor and a sub-frame 17 carrying the working tools 12, the sub-frame being swingable, during normal working, about a longitudinal axis on the carrier frame but being automatically rendered immovable when the latter is lifted. As shown, the device is a hay-tedder having a tedding cylinder 12 carried by a beam 17 which is supported by a roller 22 at the rear and is mounted on an arched carrier 9 by means of front and rear longitudinal bearings 13, 14. The front bearing is a universal joint but the rear bearing includes a slotted member 18 within which the journal 15 on the carrier can rotate freely when at the bottom of the slot 16. When the machine is lifted by the tractor, the weight of the sub-frame causes a tongue 21 on the journal 15 to enter a notch 20 in the member 18 thus locking the carrier and sub-frame together.

Filed: 1974-02-27
Abstract: 1466692 Transferring electrostatic images ADDRESSOGRAPH MULTIGRAPH CORP 27 Feb 1974 [1 March 1973] 9008/74 Heading B6C A method of transferring toner particles of a developed latent electrostatic image to a copy sheet is characterized by the provision of a constant current supply for the source of charge migration, resulting in the transfer voltage automatically compensating for changes in the transferring conditions, e.g. humidity or the material of the copy sheet. Exemplified apparatus includes a conductive backing member 11 and corona discharge device 18 connected to constant-current supply source 20, serving to transfer the developed electrostatic image on a surface 13 to a receiving surface 14. In the absence of a constant-current source, the voltage has to be manually adjusted for consistent copying; the present invention provides for this adjustment to be automatic in view of the fact that optimum transfer takes place at a particular current magnitude for a given system.
