Patent number: 4175737Abstract: An improved stop mechanism for use with machinery wherein a workpiece is advanced through one or more tooling stations comprises an arm supported for limited pivotal movement about orthogonal axes. The arm is constrained for movement within a grooved block and mounted on a pin extending through coaxial conical bores formed in opposite sides of the arm. The arm is biased in a direction opposite to travel of the workpiece to a ready position in sliding contact with the workpiece until the forward end of the arm engages a predetermined notch or locating surface on the workpiece and pivotally moves therewith to a stop position. The rear end of the arm simultaneously actuates a valve, switch or other control device to initiate the desired operation on the workpiece. After completion of the desired operation, the arm is disengaged from the notch or locating surface to release the workpiece and returned to the ready position.Type: GrantFiled: June 23, 1978Date of Patent: November 27, 1979Assignee: Krestmark Industries, Inc.Inventor: Steven K.

Patent number: 4174584Abstract: A fish lure is formed of an elongated strip. A central section of the strip is twisted so that the flat leading and trailing end portions are rotated 90.degree. with respect to each other. The combined spinning and zig-zag action of the lure is both obtained and controlled by the location of the twisted portions in the strip, the relative sizing of the twisted and flat portions, and the size of the end portions with respect to each other. The length of the twisted section which provides the action, approximates that of the trailing end portion, which acts as a stabilizing rudder. The length of the leading end portion is about one fourth that of the trailing end portion to improve the balance between the end portions and the twisted central portion.Type: GrantFiled: December 8, 1977Date of Patent: November 20, 1979Inventor: Charles R.

Patent number: 4173238Abstract: An improved trimmer section is provided for use in a sawmill, together with method and means for automatically selecting timbers and the like to be trimmed, and for automatically routing trimmed timbers to a preselected one of a plurality of different storage and loading points in the sawmill. In particular, the operator is required to select which of several stations is to receive each timber after it has been cut to a designated length. Thereupon, the timber is automatically transferred through several stages of mechanical manipulation to the designated station while, simultaneously therewith, another un-trimmed timber is promptly conducted to the trimming saws. Actuation of the entire operation is effected by merely selecting the station to receive the trimmed timber, since the cycle will repeat as long as there are timbers to be trimmed.Type: GrantFiled: December 6, 1976Date of Patent: November 6, 1979Inventors: Roy R.
