[Class 142(iv)] A winding device in a beaming machine comprises bobbins or spool: upon which spare threads are collected during beaming to provide a reserve ir the event of thread breakage A bobbin or collecting spool E rotatably mounted upon a plate C secured to a beaming machine is driven by a belt from a pulley F also mounted on the plate. A further pulley J driven from the drum of the machine drives the pulley F through a pawl and ratchet mechanism H, G the pawl H being forced into engagement with the ratchet plate G secured to the pulley F by a blade spring K and allowing the said pulley F to freely reverse if required. Instead of the blade spring, a spiral spring may be used. For building the thread on the bobbins a traversing device may be used. A slotted traverse arm P carrying a slide R is operated by a lever N through two universal joints 0, O . The lever N carries a roller which engages a uniform motion cam L driven from the drum of the machine through a pulley M.

    • 326,186. Bates, J. Dec. 3, 1928. Hand-trucks.-A tilting appliance for lifting an upended oil-drum or like cylindrical container A having ribs a and bring- ing it to a horizontal position comprises a rectangular frame 1 fitted with transverse members 2 one or more of which engage beneath a rib a of the drum as shown, with means for holding the drum against the frame, and with rockers 9 which have rolling contact with the ground from the position shown substantially to the position at which the drum is horizontal. The device may be constructed as a truck with wheels 18, and struts 19, and with hinged struts, not shown, at the forward end of the frame for support when the drum is horizontal. The drum is held against the frame during tilting by a pivoted hook 22 of adjustable length, or chains may be used. The transverse members 2 are adjustable along the frame. The handles 5 of the frame are pivoted at 7 and bear against lugs 8.
