Abstract
542,866. Work-holders ; copying-mechanism. REYNOLDS TUBE CO., Ltd., and REYNOLDS, E. A. Feb. 5, 1941, No. 1519. [Class 83 (iii)] [Also in Group XXIII] Work such as long aircraft spars of thin metal of channel section required to be machined or ground to close limits are clamped on the bed d of the machine by a bar c placed inside the channel and clear of the edges b to be machined. A roller e in proximity to the cutter exerts clamping pressure on the bar from a spring, weight or screw h. When one end of the channel retains the form of the tube from which it has been cut, the end of the bar c within the tubular portion is tapered to coact with a filling wedge i so that the bar can be held to the bed by a clamp j without damaging the work. The bar may extend beyond the tubular portion for clamping. When the spar is to be tapered, or otherwise formed, if the spar and bar c are flexible enough, a shaped packing piece may be interposed between the spar and the bed of the machine. A number of spaced rollers e on a common spindle may act simultaneously on a number of clamping bars in spars side by side.
