摘要： The invention relates to a seed planter having furrow forming means in association with a pair of furrow closing wheels each of which is independently mounted relative to the suspension of the other so that each spring biased suspension arm is pivotable to enable each closing wheel to be raised, or lowered, independently of the other wheel in response to ground conditions encountered in the operation of the planter. The closing wheel mounting also includes means for adjustment of each wheel whereby the angle of attack of each wheel may be varied and importantly enable adjustment of the wheel spacing so that the distance between the wheels can be adjusted and enabling the wheels to be set to run straight with the direction of travel of the planter and at any desired seed planting depth.

摘要： A coulter disc assembly is pulled by a tractor or other motorized vehicle to create a trench in the ground into which seeds are dispensed. This mounting arrangement of the present invention allows a farmer to inject agricultural additives, such as either liquid or dry fertilizer, into the ground so as to come into contact with the seed immediately after the trench is created and before it is covered over. The mounting arrangement consists of an elastomeric mounting block adapted to connect to a coulter disc frame. A rigid guide rod extends from the mounting block downwardly toward the ground. One end of a tube is connected to a supply of agricultural additives and the other end to the lower end of the guide rod. As the coulter disc passes through the ground to create a trench, the lower end of the guide rod is carried in the trench. As the guide rod engages the side walls of the trench, the rubber mounting block allows the guide rod to pivot rearwardly in the direction opposite the travel of the disc. Unlike prior art spring mount arrangements, the rubber mounting block allows the guide rod and connected tube to also move from side to side, eliminating the need for frequent adjustment and/or replacement of the spring mount. Thus, the guide rod can move laterally, vertically or rearwardly with the contour of the trench while at the same time always directing the treating additives into the trench.
摘要翻译： 绞车盘组件由拖拉机或其他机动车辆拉动以在地面中产生在其中分配种子的沟槽。 本发明的这种安装装置允许农民将诸如液体或干肥料之类的农业添加剂注入到地面中，以便在产生沟槽之后立即与种子接触并在其被覆盖之前。 该安装装置包括适于连接到仓库盘架的弹性体安装块。 刚性导杆从安装块向下延伸到地面。 管的一端连接到农业添加剂的供应物，另一端连接到导杆的下端。 随着砂轮盘通过地面以形成沟槽，导杆的下端承载在沟槽中。 当导向杆接合沟槽的侧壁时，橡胶安装块允许导杆在与盘的行进相反的方向上向后枢转。 与现有技术的弹簧安装装置不同，橡胶安装块允许导杆和连接的管也从一侧移动到另一侧，消除了对弹簧座的频繁调节和/或更换的需要。 因此，导杆可以随着沟槽的轮廓横向，垂直或向后移动，同时总是将处理添加剂引导到沟槽中。

摘要： A portable fireplace for burning combustible materials including a base member defining a fire chamber adapted to receive and contain the materials to be burned. One or more screen members are adapted to extend upwardly from the base member and to protect against burning embers being expelled from the fireplace. A cover member is supported above the screen members and is removable to provide access to the fire chamber when desired. A support structure is associated with the base member to support the base member at a sufficient height above a support surface to prevent the burning or scorching of the support surface. One or more of the screen members is selectively removable to provide access to the fire for enhanced viewing or cooking.

摘要： A multiple rotary hoe including individual hoe wheels mounted in front and rear rows with an individual support arm for each wheel and all of the support arms having a common axis mounted on a single pivot shaft for independent pivoting action in response to upward and downward movements of the hoe wheels with such movements counteracted by spring means exerting downward pressure on each support arm independently of all of the remaining arms.
