Abstract

168,043. Williams, M. F., and Plaisted, H. M. Aug. 19, 1920, [Convention date]. Pulleys.-In order to promote adhesion and to expel air between belts and high-speed pulleys, the face of the pulley is provided with transverse grcoves, which are deepest and widest in the middle and taper to each edge. To reduce the humming noise due to the serrated surface, the trailing flank of each groove is rearwardly inclined at a considerable angle to the radius. Figs. 1 and 2 show a crowned pulley in which the grooves are formed with a straight bottom C by a slotting-tool &c. acting parallel to the shaft, the grooves vanishing at the sides of the pulley. The leading faces A of the grooves may be radial, the other faces B being inclined. Air is discharged from the ends of the grooves, which are not covered by the belt. In flat-faced pulleys, the bottom of the groove is made concave, to produce the desired form. In the Specification as open to inspection under Sect. 91 (3) (a) the pitch and width of the grooves corresponded approximately to those of the wrinkles produced in a belt when it passes round a small pulley. This subject-matter does not appear in the Specification as accepted.
