Abstract: A gravity feed dispensing holder which is adapted to receive and dispense cans directly from the open end of a multi-can carton. The open end of the multi-can carton fits into the holder which supports the carton on its side so the long axes of the cans are horizontal and at right angles to the direction of movement of the cans toward the open end of the carton. The holder tilts the carton towards its open end to cause gravity flow of the cans toward the open end of the carton into an outer extension of the holder. The holder substantially surrounds the bottom side, the open end and the lower front portion of the top and bottom of the carton. The outer extension of the holder has an upwardly facing opening from which the cans are successively removed. Gravity feed of the cans confined in the carton causes them to roll towards the opening for dispensing.

The base comprises a tubular T-joint having two 45 degree elbows in a common plane with the T-joint, and a right angle elbow extending out from the intermediate, right angle opening of the T-joint. Removable leg sections fit into the outer ends of the 45 degree elbows to orient the base so that the outer end of the right angle elbow opens vertically upward to receive the lower end of the two-part tubular pole section. The support stand is held in place by the volleyball net and a pair of guy lines which attach to the top of the pole section and are anchored to the ground.

Abstract: An improved slow down system in sheet handling equipment which makes possible high speed handling of paper and plastic materials, including limp-bodied paper and plastic stocks, such as lightweight and recycled paper and plastic bags. In the prior high speed sheet handling systems, the slow down sections tend to jam because the limp-bodied sheets are easily deformed at higher speeds. A conventional snubber and a laydown device just following the high speed section of the sheet handling equipment lays down the trailing portion and edges of the first and successive incoming sheets, so that the lead edge of each successive sheet will clear all parts of the previous sheet. The sheets are squared by a tape slow down section, which comprises sets of adjustable slow down tapes with idler rollers and lower slow speed tapes with idler rollers, all running at the same speed. The idler rollers are adjustable so that the optimum stream can be obtained for any limp-bodied or lightweight sheets.

Abstract: A cutting tool and clamp for cutting a fishing rig or lure from the end of a fishing line and holding the line threaded through the line guides on the fishing rod in a ready condition for the next use. Removing the hooks from the end of the line prevents tangles and injuries.

Abstract: A duplex safety outlet which may be controlled from a wall switch, or remain energized, depending how the male plug is inserted into the outlet. A slidable circuit selection plate is disposed over the contacts of each outlet. The non-conducting selection plate is normally biased to a central position in which all of the electrical contacts of the outlet are covered. When the selection plate is pushed to the left, the prongs of a male plug can be inserted into the circuit which is connected to a wall switch. When the selection plate is moved to the right, the male plug can be inserted in a second circuit which remains energized at all times. Thus, the way the male plug is inserted in the outlet determines whether the outlet will be controlled from a wall switch, or whether it remains energized at all times. Each outlet can be operated separately, so one can be operated from the wall switch while the other is constantly energized, the reverse, or both the same.

Abstract: A folding boom side-ditcher which has a two-stage chain (or belt) drive from the power take-off (PTO) of a tractor. A laterally movable counterweight is provided so the folding boom has maximum side reach without danger of upset. Hydraulic actuating cylinders are provided for moving and positioning the boom and the counterweight, which are connected to the hydraulic system of the tractor in the conventional manner. The two-stage chain (or belt) drive for operating the digger head transfers more power through a two-stage reduction sprocket system, and the digging capacity at the digger head is increased substantially. This side-ditcher is more versatile because of the flexible boom, and it is considerably less expensive than the prior hydraulic drive systems of conventional side-ditchers.

Abstract: A gap cutting sheeter having controls to adjust the cutting position of the first and second flying shears relative to each other to set the gap size to a particular printed sheet. The downstream flying shear can be set up to cut the leading edge or the following edge of while the web is moving. When cutting the leading edge, a flexible flipper is provided just ahead of the flying shear to contact and push successive cut chips toward a vacuum chip removal system. Alternating vacuum removes the chips, and pulsing positive air pressure against the underside of a leading, trimmed edge guides it over the chip removal vacuum chamber to the downstream conveyor. A knockdown vane is provided just after the flying shear to press the leading edge of a cut signature against the downstream deck plate to prevent wrinkling of the cut signatures.
