  • Patent number: 4498576
    Abstract: A product conveyor lane divider for dividing cartons, tubs, jars, boxes and various products from a single infeed product lane into two product discharge lanes. The product infeed lane feeds products onto a work or separator conveyor in single file and a driven divider wheel having lugs or separating members disposed thereon engages every other product or group of products and moves it laterally on the separator conveyor for discharge onto a product discharge conveyor which discharges the two lanes of products formed by displacement caused by the divider wheel. Apparatus is included that adjusts the divider wheel to selected various heights and an angle drive mechanism is provided for driving the wheel. The speed, angle and spacing of the lugs may be adjusted to satisfy installation requirements.

  • Patent number: 4054288
    Abstract: An archery target having a backstop provided with markings representing a game animal, and the like, for forming a target area on the backstop. By constructing the backstop as a rectangular parallelepiped, markings can be provided on a pair of parallel faces in order to afford a choice of targets and to reduce wear on the backstop. The latter is enhanced by including in the markings designation of areas which are the primary target area in the animal, and by offsetting these designated areas from one another. The backstop is anchored at a desired location by a pair of rods extending through holes provided in the backstop and inserted into the ground or other support surface. An elastic element stretched between the rods above the backstop holds the backstop firmly in place relative to the internal frame formed by the rods.
