Abstract: 122,475. Hodgson, Ltd., G., and Lister, C. Jan. 24, 1918. Dobbies.-In a toothed crank-wheel dobby, detector levers pivoted upon the levers carrying the crank-wheels in positions between the fulcra of the levers and the crank-wheels are acted upon by a pattern surface of the peg-lag type on a cylinler situated in the usual position in the dobby and by a cross-bar, which raises the levers acted upon by pegs into their highest positions and retains them in such positions besides retaining the other levers in their lowest positions. The levers 2, Fig. 1, which carry the crank-wheel 3, are preferably formed of sheet-metal sides spaced apart by distance-pieces 5, 6, 7 and secured together by rivets 5<a>, 6<a>, 7<a>. Detector levers 8, formed for either long or short dwell, are pivoted on the pieces 7 and are adapted to co-operate with peglags 10 on a cylinder 11, the pieces 5 acting as stops for the upper ends of the lowered levers 8. When a lever 8 is raised by a peg, it contacts with the piece 6, and a cross-bar 12, carried by arms 12<a> on a rock-shaft 13, engages its under surface and raises it farther, so that the lever 2 is raised to cause its crank-wheel 3 to engage the upper partly-toothed drum 19. The bar 12 serves to retain both the raised and lowered levers 8 in their respective positions while the crank-wheels are being actuated by the drums 19, 15, and then recedes to free the levers 8. The shaft 13 is rocked by a lever 12b, Fig. 2, and a cam 14 on the shaft 15<a> of the drum 15.

Abstract: 157,738. Farr, F. G. Jan. 19, 1918, [Convention date]. Direct liquid-pressure apparatus. - In systems wherein the oil is stored over a displacement liquid, such as water, overfilling and consequent displacement of oil into the drain are prevented by means of a pipe H, which extends into the oil tank A to near the bottom and communicates with a chamber I, so that when the oil reaches its lower limit of level, oil rises in the pipe H and raises a float J, whereby a valve K in the oil inlet pipe C, or a valve L in the water discharge pipe D. or both such valves, are closed by lever and link mechanism M, thus automatically stopping the filling. After the float J has operated, oil is drawn off from the chamber I by means of a cock Q to permit the dropping of the float and the opening of the valves. The Specification as open to inspection under Sect. 91 (3) (a) describes a non-automatic construction, in which the pipe H, which may be led out of the side of the tank, indicates overfilling by a discharge of oil therefrom, and a valve therein is opened by connecting-links &c. when the valve E is operated to connect the pipe D to the drain G, and is closed when the valve E connects the pipe D with the displacement head F. This subject-matter does not appear in the Specification as accepted.
