摘要： A mobile camper arrangement is disclosed wherein two camper bodies of different shapes are mounted on the same towable trailer. One of the bodies is shaped to fit into outer recesses of the other body in order to effect maximum utilization of space on the trailer. Accordingly, a second camper body can be shaped to fit together with one that was previously purchased and which was specially shaped to fit snugly into the walled bed of a pickup truck. A useful combination is thus provided whereby the previously purchased camper body for a pickup truck does not have to lie unused or be disposed of when a larger mobile camper is needed.
摘要翻译：公开了一种移动式露营装置，其中两个不同形状的露营器主体安装在同一拖车上。其中一个主体被成形为适合于另一个主体的外部凹槽，以便最大限度地利用拖车上的空间。因此，第二露营器主体可以被成形为与先前购买的那个配合在一起，并且被特别地成形为紧贴地装配在皮卡车的围墙床中。因此，提供了一种有用的组合，由此，当需要较大的移动式露营者时，先前购买的用于皮卡车的露营车体不必置于未使用或被处置。

摘要： A latching yoke is pivotally attached to the main brace of an earth working implement having a wing frame which is rearwardly foldable. Elongated, flexible cables extend rearwardly and outwardly from the main frame to the outer ends of the wing frame and arm members, pivotally attached to the main frame, receive one end of the cables for preventing slackening thereof when the wing frame is folded from an operating configuration to a transporting configuration, or vice versa. A wing frame lifting tower is on the main frame and has a lever operating an actuator rod. When the wing frame is in the operating configuration, the arm members are folded forwardly and inwardly and the outer ends thereof are latched by the yoke which has an opening through which the rod extends and is freely movable. Adjustable yoke engaging members are spaced along the rod to determine the positions of the wing frame when the arms are latched for operation and unlatched for transport configuration.

摘要： An improved chain lifter for foldable soil conditioner apparatus of the general type characterized by an elongated, foldable wing frame for soil conditioning members which is hingably mounted transversally on the rear of a main frame, is liftable from the ground by means of a lifting tower on the main frame, and is stabilized by reinforcing chains which extend rearwardly and outwardly from the main frame to the outer ends of the wing frame. Arm members which lift the chains have one end pivotally attached to the main frame whereas the other ends of the members are secured to the reinforcing chains intermediate to the ends thereof. Resilient biasing links interconnect the arm members with the upright lever of the lifting tower. Accordingly, the arms are pivoted upwardly and forwardly by means of the resilient biasing links when the wing frame is folded to a transport position, hence lifting the slackened reinforcing chains off the ground.
摘要翻译：一种用于可折叠土壤调节装置的改进的链条升降机，其特征在于一种用于土壤调节构件的细长的，可折叠的翼框架，其横向地安装在主框架的后部，可通过提升塔从地面上提升主框架，并且通过加强从主框架向后并向外延伸到机翼框架的外端的链条来稳定。提升链条的臂部件具有一端可枢转地附接到主框架，而这些构件的另一端固定到中间到其端部的加强链条。弹性偏置连杆将臂构件与升降塔的直立杆相互连接。因此，当翼架被折叠到运输位置时，臂通过弹性偏置连杆向上和向前枢转，从而将松弛的加强链提离地面。

摘要： An attachment for an earth working apparatus having a mobile frame with central and wing sections, each with forward and rear frame members and a plurality of earth working members thereon. The attachment includes a plurality of reach arms for each section and having a forward end portion thereof connected to the forward and rear frame members of the respective frame section. A vertically adjustable hanger unit is swingably mounted on each reach arm and has a tool bar carrying support member swingably mounted thereon. Each hanger unit is constructed so as to permit an elongated, adjustable drag tension spring to have unusually great length such as by allowing a lower end portion to be connected to the respective support member rearwardly of the hanger unit and an upper end portion to be connected to the respective reach arm forwardly of the hanger unit.

摘要： An improved subsoil plow assembly to be attached to an implement frame employs a soil-splitting leading edge of arcuate cuspate shape, breaking the earth but inhibiting the mixing of the subsoil with the topsoil. That portion below the cuspal apex tends to split away and sidewardly while the portions above the apex are directed upwardly. The plow is preferably comprised of laminate construction providing strength and particular suitability for forming a channel therein directing passage of gaseous or liquid fertilizer into the soil. An alternate embodiment includes a pocket on the leading edge accepting removable and replaceable cuspal inserts useful in differing soil conditions.

摘要： An earth tillage apparatus has a hydraulically liftable, foldable carriage with sections which extend laterally from a tongue to a wide field working position and are foldable to a narrow transport or storage position. Rigid structural arms are hingedly mounted on the tongue and have free ends extending laterally a substantial distance therefrom. In a preferred embodiment, cables respectively have one end secured to the tongue and the other end secured to the wings and extend through a pulley mounted on each of the arm free ends for the purpose of positioning the point of pull a substantial distance laterally of the tongue thereby reducing the tendency for inwardly buckling the carriage. The arms are locked in their laterally extending position when the wings are in the wide field position and are selectively released to hingedly move to a second or transport position when the wings are folded. The arms and cables are arranged relative to the tongue and carriage to maintain cable tension and prevent dragging thereof.

摘要： A wing folding or lift kit adapted to be easily installed on the central frame members of foldable, multi-sectioned earthworking implements to selectively move pivotally mounted side sections or wings. A centrally mounted floating hydraulic cylinder has linkage arms hinged on the ends thereof, with the outer ends of said arms attached, by lost-motion links, to cross members of the wings. In cylinder-extended position, the wings are free to follow ground contour without "working" the cylinder. Upon contraction of the cylinder, the wings are rotated or folded.
