Abstract

103,367. Smith, A., and Perks, T. Feb. 15, 1916. Smallware looms. - The usual shuttle-actuating bar is reciprocated by link-work from a crank actuated by continuously rotating wheels of eccentric and elliptical character in such a manner that the bar is caused to dwell at each end of its path of motion for equal or approximately equal periods of the desired length. The bar 2, Fig. 1, is reciprocated on the lay B by a lever 3, an adjustable connecting-rod 7, a bell-crank lever 8, and a connecting-rod 9 from a lever 10 pivoted at 10<a>. This lever is connected by a pin 11<a> and a rod 11 to a crank-pin 11<b> on an eccentric toothed wheel 12 gearing with a similar wheel 15 on a shaft 16, which is driven from a motor shaft 19 by an eccentric wheel 18 and an elliptical wheel 17 twice the size of the wheel 18. The lever 10 is caused to dwell when the crank-pin 11<b> is passing top centre, by reason of the approximate coincidence of the arc c, which is the path of motion of the pin 11<b>, with the portion between the radii a, b of the are d struck with the top or dotted position of the pin 11<a> as centre. An approximately equal dwell at the bottom centre is obtained by arranging the wheels 12, 15, 17, 18 so that the slowest motion of the wheel 12 occurs at this time. The shuttle-actuating bar may act on the shuttles through pins raised and lowered by cam-grooves; or the pins 20, 20<a>, Fig. 4, may be actuated, as the bar 2 moves, by levers 25 engaging crank-pins 26<a> on partly toothed wheels 26 actuated by stationary racks 27. The crank-pins on the wheels may, alternatively, engage slots in the supports for the pins. The parts are adjustable as regards the distance between the pins 20, 20<a>. According to the Provisional Specification, the equal wheels may be dispensed with, and the shuttle-operating lever actuated from a crank-pin on the large elliptical wheel through lever devices suitably arranged to give the requisite dwells.
