Abstract: A cross arm unit for supporting wires such as in a grapevine supporting trellis. The cross arm unit has an elongated arm member which is secured to a socket member transversely related to the arm member. The end portions of the arm member are reverse curled with the ends being spaced from the remainder of the arm member to provide wire-passing slots. In one form of the invention the socket member is of square cross section with the arm member bisecting the passageway of the socket member so as to form a stop facilitating frictional mounting of the cross arm unit of the top of a post. When the post is of standard metal construction, the socket member will be arranged so that the arm member crosses its passageway diagonally. When the cross arm unit is intended for mounting on a wooden stake, the socket member will be arranged so that the cross arm member is normal to one set of side faces of the socket member but parallel to the other set.

Abstract: A controlled stop circuitry which frees the operator for carrying out other duties of cycle-interrupt time, by being automatically operable, when once activated, to partially raise the electrodes and to open the transformer switch, but only after the electrode current has decreased to a safe value. More particularly, the circuitry when actuated in a designated manner, interrupts an operating cycle by raising the electrodes, while simultaneously sensing the current supplied to them, and is effective, when the current decreases to a safe level, to automatically open the transformer switch and stop movement of the electrodes in partially raised positions. The circuitry also permits, as an option to the above procedure, the carrying out of the above steps, except that it delays opening of the transformer switch until the electrodes reach the top of their travel.

Abstract: A white cap dipper apparatus for metal fence posts and a method of dipping such posts, wherein the apparatus includes a shuttle car having a tilt frame for removing posts in successive groups from horizontal flow path cables, successively elevating such posts and dipping the same, and then returning the posts to the cables in horizontal position. The car reciprocates back and forth in the dipping zone in such timed relation to the flow path and with such speed that while it creates a gap in the flow path, it does not interrupt the continuity of the flow.
