Abstract
726,501. Hat stretching apparatus. FAILSWORTH HATS, Ltd., and SYDNEY, E. July 31, 1953, No. 21328/53. Class 63. In hat stretching apparatus, pivoted elements 12 engage within the hat and cam, lever and eccentric mechanism impart successive spreading and contracting movements to the elements 12 in such a way that the extent of each spreading movement is greater than that of the contracting movement, whereby the spreading effect gradually increases. The hat engaging elements 12 are pivoted to the framework at 10 and carry rollers 14 which are engaged by a conical head 9 on a shaft 16 reciprocally mounted in the framework. A lever arm 18 is pivotally mounted on a spindle 17 and carries at one end a pivotally mounted bell crank lever 19, one arm 20 of which is connected by links 22 to the end of the shaft 16, whilst the other arm 26 is linked by a connecting rod 28 to a strap 30 of an eccentric 31. A cam follower roller 33 carried by the lever arm 18 engages a cam 35 on a shaft 36 which carries a pinion 37 engaging the smaller gear wheel 38 of a compound gear wheel, the larger wheel 40 of which engages a small pinion 41, rotatable on the spindle 17 in turn engaging a smaller pinion 42 fixed to the spindle 43 of the eccentric. The gear ratio is such that the cam 35 is rotated at about 11 r.p.m. while the shaft 16 is oscillated at about 230 r.p.m.
