  • Patent number: 4229932
    Abstract: A pea harvester incorporates a threshing device and a system, known per se, which maintains the device in a fixed orientation in space irrespective of the ground contours. To feed the threshing device a series of conveyors is pivoted so that these can continue to supply the threshing device without crop loss even if a local ground irregularity deflects a forward pick-up reel which discharges on to a first one of the conveyors. The pick-up reel has a width at least equal to the widest track of the harvester wheels and the first conveyor has substantially the same width. A number of cleaning stages is incorporated and peas are received from the threshing device by two inclined vibratory conveyors the inclination of each of which is adjustable. A hopper assembly for peas is arranged forwardly of the threshing device and includes an auxiliary hopper which automatically takes the place of the main hopper when the latter is moved to its discharge position.

  • Patent number: 4221075
    Abstract: A simplified combination animal call has a casing divided into identical upper and lower half sections held together by a securing elastic band. Symmetrical channels of different widths spaced longitudinally along half sections provide airways through the casing whose openings act interchangeably as mouthpiece openings along one side of the casing and sound-emitting bells on the opposite side. Air blown through any such airway vibrates a second elastic band which spans each airway to produce an animal-like sound. Multiple airways of different widths make available several different pitch ranges at once. Changing either the size or tension of the vibratory elastic band changes the pitch that is available at each slot. Finally, the pitch produced may be dynamically varied either by changing the tension on the vibratory elastic or by compressing the mouthpiece side of the casing while the device is in use.

  • Patent number: 4219992
    Abstract: A row crop attachment adapting a combine for efficient harvesting of soybeans and similar crops, has crop-receiving structure disposed forwardly of the cutter for catching beans prematurely separated from the stalks by action of the combine cutter. Multiple, spaced, crop-receiving divider pans for support on the combine in generally underlying relation to the beans define a number of stalk-receiving throats extending fore-and-aft of the combine ahead of the cutter; respective opposed pairs of crop-catching wings are pivotally mounted on the pans for swinging movement in a generally horizontal plane to and from positions closing the throats. In preferred forms, each pair of wings is yieldably biased toward its throat-closing position to maintain the width of the throats at the minimum dimension required to allow passage of stalks to the cutter, whereby the crop-receiving structure presents a substantially continuous expanse for catching prematurely separated beans.

  • Patent number: 4219619
    Abstract: A vibrator utilizing a disposable bite probe subject to vibrations of the vibrator is used to seat crowns, bridges and the like. After cement has been applied to the underside of the crown and the prepared tooth surface and the crown initially positioned, the bite probe is received between the crown and opposing teeth in the patient's mouth or dentist's finger in the absence of opposing teeth, the patient or dentist applying pressure on the bite probe. When the vibrator is energized, the vibrations express excess cement working the crown down into a proper and secure position on the patient's tooth. Continued pressure on the bite probe by the patient and/or dentist holds the bite probe in position, the vibrator itself being disconnected from the probe and the probe itself being retained in a stationary position for a sufficient length of time to assure proper seating of the crown as the cement hardens.

  • Patent number: 4214422
    Abstract: Gathering conveyors of the forage harvesting header deliver upstanding, severed crop stalks by their lower ends to an outlet toward which all conveyors of the header converge. The upper ends of the crop stalks are guided and gathered laterally inwardly by apparatus above the conveyors, and a transversely disposed knock-down bar just forwardly of the outlet leans the stalks back toward the front end of the header as they approach the outlet so that the stalks tend to enter and pass through the outlet in a butt-first condition. The knock-down bar is mounted so as to yield upwardly under the influence of crops passing therebeneath in the event that the volume of the crops is so great that they could otherwise not pass through the restriction formed by the knock-down bar on the one hand and the conveyors on the other hand.
