Abstract: Two cylinders telescopingly receive a third between them, one of the two is on a quadripod mount. Handles pull said two cylinders together and put air pressure on a soil engaging instrument. The greater the downward pull on the handles, the greater the air pressure and the greater the torque, through a helical cam, on the instrument. The top cylinder carries a recorder which marks a strip chart on a drum with the soil shear strength (torque) as a function of the vertical load (air pressure) on the instrument. The chart is carried on supply and take-up spools mounted on the underside of the recorder drum, slotted to permit chart movement.

Abstract: A wheel in which the load bearing portion adapted to engage the ground is essentially in the form of a multiplicity of spring convolutions. In a preferred form these convolutions form parts of a continuous helically coiled spring bent to extend around the periphery of the central portion of the wheel.

Abstract: A sign assembly for use on a vehicle having at least one generally vertically adjustable window for mounting a clamp portion of the sign thereto. The clamp portion supports a standard and frame section of the sign assembly generally upwards and above the roof of the vehicle in order for the sign to be visible from all directions. Adjustment and locking means are provided on the standard to provide substantially vertical positioning of the sign regardless of the configuration of the window edge. In a first embodiment the sign has a flag portion mounted to the frame section which is rotatable in order to attract attention. The sign frame section is adapted to easily mount and dismount different flag portions to the assembly and at the same time to hold the flag portions taut and securely mounted. In a second embodiment, the sign is securely fastened to the standard and adjustment means are provided not only to vertically position the sign but also to adjust and lock the sign in any axial rotational position.

Abstract translation: 一种在车辆上使用的标志组件，其具有至少一个大致垂直可调的窗口，用于将标志的夹具部分安装在其上。 夹具部分通常在车辆顶部上方和上方支撑标牌组件的标准和框架部分，以便从各个方向看到标志。 在标准上提供了调整和锁定装置，以提供符号的基本上垂直的定位，而与窗口边缘的配置无关。 在第一实施例中，符号具有安装到框架部分的标记部分，其可旋转以引起注意。 符号框架部分适于容易地安装和拆卸组件的不同的标志部分，并且同时保持标记部分被拉紧并牢固地安装。 在第二实施例中，符号被牢固地固定到标准上，并且不仅设置垂直定位符号而且提供调节装置，而且还可以将符号调整和锁定在任何轴向旋转位置。
