Bottles 11, which are carried in upright position by an endless conveyer 12, are transferred by mechanism 48 to a conveyer 16 and deposited in horizontal position in cradles 14 mounted thereon. The mechanism 48 comprises an endless chain having pairs of rollers 47 mounted on its side at intervals. These rollers form a support for the neck of the bottle during lowering. The platform 21, on to which the bottles are deflected by a guide 19, has a series of slots 22 through which pass a series of plates forming a rotary transfer member 23. The plates extend from a common hub 24 fast on a shaft 26 and each is formed with four operative surfaces ending in an abutment 44.

Abstract: 796,553. Textile spindles. UNIVERSAL WINDING CO. Dec. 6, 1955 [July 7, 1955], No. 35028/55. Class 120(2) A textile spindle and mounting comprising a spindle supporting member pivoted to a fixed bracket and a spring normally urging the supporting member to a position in which the spindle contacts a driving belt is characterized by having an operating linkage for pivoting the supporting member, the linkage comprising an actuating lever pivoted at one end to the bracket and a link pivoted at one end to the lever and at the other end to the supporting member such that movement of the actuating lever pivots the supporting member and spindle away from the operative position and moves the link through a central position to lock the supporting member and spindle in an inoperative position. As shown, the invention is applied to a false twist spindle comprising a blade 49 journalled in a pivoted mounting 50. The blade 49 is provided with a cylindrical head 54 and a sleeve 56 carrying a wear resistant bushing 57. A wheel or sheave 60 is rotatably mounted in the head 54. The mounting 50 comprises a fixed bracket 63 secured to a spindle mounting bed 48. The bracket 63 is provided with two lugs 69, 70 in which is fixed a hinge pin 73 which supports the spindle blade carrying section 74 in a pivotal manner. This section 74 is open at its rear side so as to expose the mid portion of the blade 49 which functions as a whorl to be engaged by a spindle driving belt 77. Guides 37 and 100 are mounted at either end of the device. A spring 78 functions to pivot the spindle blade carrying section 74 so as to press the whorl against the driving belt. An over centre linkage is provided for moving the spindle blade carrying section to and from the driving belt and comprises a lever 85 pivoted at one end 86 and a arcuate link 87 pivoted at one end to a pin 88 intermediate the ends of lever 85 and at the other end to a boss 89 formed on the blade carrying section 74. A brake block 95 is housed within the section 74 and is caused, when the whorl is moved away from the driving belt, to engage the whorl and bring the spindle to rest.

Apparatus (Fig. 2) for manufacturing the device consists of a hopper 25 feeding fluid sponge forming mass of viscose 26 on to an endless belt 22 and a roller 30 for guiding fibrous web 27 on to the upper surface of the sponge forming layer which it penetrates to a depth governed by the viscosity of the sponge fluid and the height of fluid.  The belt 22 carries the combination through a sponge generating coagulation and regeneration tank 32.  Coagulation is effected by passing an electric current through the mass and regeneration by then immersing the coagulated mass in a hot aqueous liquid above the cellulose regenerating temperature.  Other suitable sponge materials include polyurethane, plasticized polystyrene, and gelled polyvinyl alcohol. Before use the sponge member may be impregnated with a detergent-containing gel, e.g. comprising 5-6% water, 15-40% polyhydric alcohol, 20-55% water soluble soap and optionally 5-30% emulsifying agent.
