Abstract: <PICT:0910628/IV (b)/1> <PICT:0910628/IV (b)/2> <PICT:0910628/IV (b)/3> A hosiery-treating machine having a rotatable carriage carrying a plurality of upwardly extending hosiery forms each tiltable from a vertical position to a tilted loading position is provided with actuating mechanism separate from the carriage and comprising a fixed cam surface engageable with the forms to tilt each in turn to the loading position, and a driving cam in the form of a worm engageable successively with each of the forms while in the titled position to effect rotation of the carriage and return the form rapidly to the vertical position.  The machine shown includes frame 11 which supports a pair of tracks 12 on which ride carriages 14. The latter have pivotally mounted thereon a plurality of supports 15 each carrying a stocking form or board 16.  The treating zone of the machine is located within the bell 20 which is movable vertically.  Two carriages 14 are provided, one being within the bell 20 for treatment of the stockings thereon while the other is disposed at one of the ends of tracks 12 for loading or unloading of the stocking forms by the operator. Mechanism 30 for automatically actuating the individual forms is situated within a housing 25 and is raised to its operative position by suitable lift means such as a hydraulic cylinder 27. The form actuating mechanism includes a cam 31 which is in the form of a curved inclined bar which fits within a recess 15a in the form supports 15 such that as the supports 15 ride up the cam 31 the forms are tilted forward to a loading position.  As the form operating mechanism 30 is raised to its upper operative position it is automatically caused to engage the cam 31 with a plurality of form supports.  Each carriage 14 is rotatable on a plate 13 so that the forms can be brought in turn to the loading position. The form operating mechanism also includes a motor-driven rotary cam 38 in the form of a worm which engages pins 37 on the form holders 15 so as to push the latter around so that they ride up the cam 31 in turn to be tilted to the loading position.  The cam 38 is also provided with a lip 38a which co-operates with the pins 37 on the form holders 15 to return the formers to the vertical position after they have passed the loading position.  The cam 38 is arranged to be discontinuous so that it imparts an intermittent motion to the carriage 14 and the latter is provided with detents 48 engageable by a ball member 47 so as to temporarily hold the carriage 14 stationary to allow loading or unloading of the respective form.  Controls are provided to enable the operator to control the length of time the carriage 14 is stationary or it may be automatically arranged so that the dwell period for each form is constant.  When an operator has loaded all the forms 16 with stockings, the hydraulic cylinder 27 is operated to withdraw the mechanism 30 from its operative position, the treating dome 20 is raised and the carriage 14 pushed thereunder and the other carriage removed therefrom to the opposite ends of tracks 12 for removal of the stockings thereon and reloading with untreated stockings.  Specification 826,404 is referred to.
