Padworth, Reading, Berkshire (England) Provision for marking building locations.

The invention relates to devices for use in marking out or defining building locations.

When marking building locations, it is customary to Use optical straightening techniques to ensure that corners of a designated area are rectangular Recently, a device has been proposed for use in optical straightening with two straightening paths, the Are arranged at an exact right angle to each other · These directional paths can be created by two telescopes be whose axes are at right angles to each other · Sin · such a straightening device is adjustable on an cantilevered support attached by a tripod or tripod and si · has a vertical axis, which the axes the telescope intersects and with the axis of a

warts extending tube coincides, in which a Rod is slidably guided. The rod can be in any position relative to the tube by means of a thumb screw and it has a pointed or cup-shaped lower end.

The lower end of the sliding rod creates the actual reference point after the device is properly set up, and this reference point can be identified by means of a marker which is placed in the ground in alignment with the said lower end of the rod or. τ * sized so that after digging through Einwärtsprojizleren the original conceptual marking position can again be received · This Project is a compli- P tends to process and leads to an increase in the costs of pricing or putting up a building location.

The invention consists in a device for use in marking out a building site by broadcasting of coordinates of a corner reference point of two arbitrary points «those of the corner reference point in at a distance are a recovery of the corner reference

Point after. Enable desire. The device includes two arms pivotally connected at one end and means for engaging at their other ends with fastening parts or position determination parts that can be driven into the ground, the Arrangement is such that when the pivot point of the two arms is in alignment with the corner reference point is located and the engagement means are at the other ends of the arms with position determination parts in engagement and the latter are driven into the ground, the device can be removed from the orientation parts can and the corner reference point through said pivot point is recovered, the device wsnn again is brought into engagement with the orientation parts

The invention is explained below with reference to the drawing, for example:

Fig. 1 is a perspective view of a labeling device according to the invention

Fig. 2 is a perspective view of an i

Position determining device which is in engagement with one end of an arm of the device according to Fig. 1 is shown · Flg. 3 is a view of the location determining device

according to FIG. 2 on an enlarged scale. Figure 4 is a top plan view of the labeling device according to the invention in its position of use

The recording device has two arms 1 and 2 attached at one end by a rivet or bolt 3 are pivotally connected, which has a tip 4, which conveniently in a position in alignment with the vertical • Achae of the known optical straightening device according to the above Description can be brought · At the other end of each arm 1 and 2 has a hole 5 »that of a stop 6 and a shoulder 7 which carries a thumb screw 8 is flanked.

* Fastening parts or positioning parts 9 are

provided that can be driven into the ground. The position determining parts 9 have shafts 10 via which the arms 1 and 2 are brought into engagement by means of the holes 5 The shaft 10 of each position determining part 9 is attached by a plate 11, the tips 12 to Setting the position determining part 9 in. Has the ground. The thumb screws 8 enable a secure ■ Attachment of arms 1 and 2 to shafts 10.

If a corner reference point for a building layer is through

w using optical alignment apparatus, or obtained by any other known device is brought the tip 4 of the device according to the invention in alignment with the corner point of reference and the arms 1 and 2 are auseinandergespreitzt so that a reasonably broad base between the holes 5 created is, it is not necessary that the arms 1 and 2

909884/0328

lie at right angles to each other 9 are driven into the ground at points determined by the holes 5, whereby the two Arms 1, 2 of the device are held by the two position determining parts 9, so that the tip 4 is stationary is held. After the position determination parts 9 have been driven into the ground, the device can are removed from them, leaving the orientation parts 9 in the ground If.it is desired, To regain the corner reference point, it is only necessary to re-attach the device to the position determining parts 9, after which the tip 4 is again brought into alignment with the corner reference point

Since the position determining parts 9 are arranged at a certain distance (for example half a meter) from the corner reference point, the Au; chachten the building location conveniently be carried out after the device has been removed from the position determining parts 9 · If desired, the orientation of parts can advertising driven 9 to such an extent into the soil i to that it is located below the level of the ground, so that an excavation machine or the like can run over them without moving them out of their position
