Abstract:
A combination tool includes a surveyor's rod having a tubular body and a hammer that is slidable within the tubular body using an external handle. The tubular body defines an opening to insert a nail to be hammered into a surface below the tubular body. A nail-loading device may be affixed adjacent to the tubular body. The nail-loading device has a tube for receiving a nail and a lever arm that can be pivoted away from the tube to receive a nail and then pivoted back to its resting position to force the nail into the tubular body through the opening in the tubular body. A hammer-stop may be affixed to the tubular body to form a physical stop to the downward movement of the hammer. A handle lock may be employed along with a rod-tip point.
Abstract:
A geodetic device is described, especially on a theodolite or a tachymeter which is provided with an arrangement for adjustment over a ground point or base point. It comprises a leveling base in which a bushing provided with a continuous center bore hole can be fastened and an upper part or alidade with a telescope which is pivotable about a horizontal tilting axis. Further, a first apparatus is provided for leveling the device in a horizontal plane and for displaying this plane, and a second apparatus is provided which comprise an objective imaging the ground point on a sensor arrangement. The arrangement for adjustment over a ground point is arranged between the leveling base and the upper part and is fixedly connected with the leveling base. It comprises a vertical spindle bushing with a hollow vertical spindle which is mounted therein and carries the upper part. This vertical spindle bushing is adjustable together with the vertical spindle in the coordinates of the horizontal plane relative to the leveling base.
Abstract:
A device for holding a surveyor's range pole in a vertical position. The pole is held rigid relative to a tripod base by a single bracket. The bracket is seated on the apex of the tripod and includes a collar member attached to an underlying three channel frame. Three horizontally disposed screws thread through the three channeled frame to mutually engage a range pole at the center of the collar.Additionally, an extension arm may be secured to the top of the collar by means of an overlying pressure plate. The extension arm lies between two upright screws which pass through the pressure plate, and pressure is exerted on the extension arm by tightening wing nuts over the screws. The range pole is secured beyond the rim of the collar by passing it through a teardrop shaped aperture in the extension arm and pressing the pole against the edges of the teardrop shaped aperture by an adjustable screw threaded through the extension arm. A ring member similar to the collar member can be used in place of the teardrop shaped aperture as an alternate means of securing the range pole to the end of the extension arm.
Abstract:
A surveyor's rod apparatus including a plurality of sections which may be selectively connected together in end-to-end relationship to provide an elongated surveyor's rod that is visible over relatively long distances regardless of obstructions including vegetation and terrain between the rod and a sighting or surveying instrument. At least one section of the rod includes a leveling device to make certain that the rod is disposed along a vertical axis in the plane of the sighting instrument. The lower section of the rod is selectively connected to a base in a manner such that the base may be used for providing a flat area on which the base is subsequently located, or the lower section of the rod may be connected to the base in a manner that the base may be driven into the ground at a fixed location.
Abstract:
The present invention relates to a scale for use in measuring and straightening damaged vehicles in a so-called vehicle alignment apparatus, especially when the measuring is made by using a laser beam, said scale including a fastening means for freely depending fastening of the scale at certain locations on the vehicle, a scale body having a graduated scale, and a line cross that is adjustable to selected position in relation to the fastening means, the graduated scale indicating the distance of the line cross from a predetermined reference point, preferably the joint between the fastening means and the vehicle.
Abstract:
A system and method for determining a position and orientation (e.g., pose) of a rigid body. The rigid body may be a position enabled projector, a surveying rod, a power tool, a drill robot, etc., in a given space. The position of the rigid body is specified by a set of three coordinates and the orientation is specified by a set of three angles. As such, based on these six values, the position and orientation of the rigid body can be determined.
Abstract:
A graphics-aided geodesic device is provided. The device may include a display, camera, distance meter, GNSS (Global Navigation Satellite System, including GPS, GLONASS, and Galileo) receiver and antenna, and horizon sensors. Data from the camera and horizon sensors may be displayed to assist the user in positioning the device over a point of interest. In one example, the distance meter may be used to determine the position of the point of interest. In another example, images of the point of interest taken from multiple locations may be used to determine the position of the point of interest.
Abstract:
A combination target reflector, light emitter and bracket assembly is disclosed for use in marking points during the taking of a land survey. The combination is pivotally connected to a central rod of a target tripod or a tripod that supports a target reflector. The disclosed combination includes first and second arms and a light emitter that is held in axial alignment with the target reflector. The first arm is pivotally and perpendicularly connected to the central rod of the tripod. The second arm is perpendicularly connected to the target reflector and the light emitter. The tripod can be moved close to a point to be marked, the tripod can be adjusted to plumb the target reflector and then the second arms, light emitter and target reflector can be moved out of axial alignment with the rod to mark the point without moving the tripod. As a result, the conventional trial and error procedure currently employed can be avoided.
Abstract:
A measuring instrument is described for application to the end of a circular member, such as a pipe, to locate the precise center of such circular member, and project it to a distant surface.
Abstract:
A laser scanner 50 includes a laser 76 affixed to a pendulum 66 with a damper 80 for damping the movement of the pendulum 66. The laser scanner 50 is controllable through a remote control 62 for positioning the laser beam as desired. Both horizontal and vertical laser beams can be projected in order to orient the laser scanner 50 with respect to gravity and simultaneously elevation.
