Abstract
225,087. Linen Industry Research Association, and New, G. F. Jan. 15, 1924. Yarns and threads, testing. - Comprises a machine whereby a plurality of specimens may be simultaneously subjected to a rubbing or rubbing and bending test and whereby a predetermined number of rubs or rubs and bends may in a given time be given to the specimens under a given tension. The machine comprises a panel 1 on which the threads 2 to be testea are arranged vertically their upper ends being clamped to an adjustable bar 3<a> while the lower ends are connected to and tensioned by lengths 4 ot squared rod guided in square holes in a plate 5, thus preventing the threads from untwisting. The rubbing device comprises three rows 8<a>, 8b, 8<c> of hardened steel pegs bolted to a metal plate 8. The middle row of pegs are shown in alignment with the outer rows, but if desired they may be set out of alignment to increase or decrease the rubbing. The plate 8 is reciprocated by a balanced crank 9 and a counter 10 indicates the number of reciprocations of the rubbing plate. This number may bd recorded by the device shown in Fig. 4. A ratchet wheel 12 is moved step-bystep through pawls 13, 14 from a cam 15 and advances a drum 11 on which rest markers 17 which when the weights 4 drop due to a thread breaking take the position shown in dotted lines. Instead of the clamps 3 shown, the thread may be passed from the weight 4 over top guide rollers to a counterweight. A spring clamp grips the thread at the top and is held closed by a catch which is released when the thread breaks, the thread being pulled away by the counterweight. The motor circuit is provided with a mercury switch and when any of the weights 4 drop on to a bar 27 the switch breaks contact.
