  • Patent number: 4155181
    Abstract: An excavating and loading system is disclosed which includes a vehicle with an excavating wheel assembly at the front and plurality of conveyors toward the rear. The excavating wheel assembly comprises individual excavating wheels including a plurality of digging buckets. Each bucket comprises a wall supported for pivotal movement between a material receiving position and a material dumping position. A predetermined cam track is disposed around the axis of rotation of the buckets and is engaged by a plurality of cam followers each connected to one of the movable walls to thereby positively pivot the movable wall of each digging bucket between the material receiving and the material dumping positions.

  • Patent number: 4144808
    Abstract: An electrophotographic print marking apparatus for printing markings on rolled steel plates while the steel plates are being fed in a heated condition. A part of an image transfer belt which is brought to a transfer section where the powder image carried by the belt is transferred to the steel plate is made movable up and down by means of a pair of lower rollers. The rollers are moved up and down to bring the part of the belt in the transfer section close the steel plates when the powder image is transferred to the steel plates and to separate the belt far apart from the steel plates when the powder image is not transferred. A tension roller is provided to absorb the change in tension of the transfer belt accompanying the up and down movement of the lower rollers.

  • Patent number: 4100687
    Abstract: A vertical augered snow removal device in which the augers rotate, in unison, toward the fan opening, at the center, back of the augers; which lift and throw the snow through the fan opening to the ejection device or rotor fan mounted behind the augers.The augers are arranged in side by side, relation to each other; two pairs of twin augers mounted at each half of the frontal area, rotating in unison toward the fan opening, at the center; the outer augers feeding the snow to the inner augers which actually throw the snow, rearwardly, in a common tangent, through the fan opening, into the rotor fan.The open sides or ends, permit maneuveribility into the snow banks at the sides when the device is moved parallel to the highway in snow removal operations on snow banks, which can readily be removed with a rotary, which breaks up the snow sufficiently, in order to feed the snow to the fan.The augers on one side of the rotary have a helical pitch or slope opposite from the augers on the other side.
