Abstract

Arbor 1 carries weight 2 which is free to rotate so that pointers 11 and 12 remain vertical such that wherever the framework carrying arbor 1 and dials 19 and 20 is placed, a true angle will be apparent on both dials 19 and 20. Grub screws 13,14 allow adjustment. <IMAGE>

Description

SPECIFICATION Precision level This invention relates to a precision level.

Levels are well known instruments, consisting of resin or rubber protected vials of liquid encased in wood or metal of varied lengths, when in use they help to obtain said levels, and in required instances, left or right angles.

Levels as such are limited to these three planes.

The invention presented herewith, although similar in appearance is quite different in effect.

Gravitational pull brings rapid inertia to weighted needles revolving on an arbor, giving accurate readings of any given angle on enclosed dials.

Specifics of this invention will now be described by way of example, with reference to accompanying drawings.

Figure 1 shows arbor in perspective, on which the weight will rotate.

Figure 2 illustrates front and end view of weight.

Figure 3 indicates shape of needles.

Figure 4 grub-screws.

Figure 5 depicts spacing pieces.

Figure 6 shows twin inner dials.

Figure 7 illustrates prepared weight.

Figure 8 gives end view of unit.

Referring to drawings, this level is comprised of an arbor, Figure 1, centrally circular 10, Figure 1, to width of weight, Figure 2, remainder being squared to outer limits.

Weight, Figure 2, would be drilled just above centre of balance, as seen in end view, Figure 2, and be fitted with twin needles, 11. 12, Figure 3, plus grub-screws, 13. 14., Figure 4, one on each shoulder, flush with shoulder.

Centrally squared spacing pieces, Figure 5, would be allocated one each side of weight 2, 15, 16, and again 17, 18, outside each inner dial, 19, 20, Figure 6.

Figure 7, illustrates front and end views of a prepared weight 2, affixed needles 11. 12, Figure 3, are angled as shown, for the purpose of rotating freely round perimeters of inner dials, 19. 20, Figure 6, offering clear readings, grub-screws, 13. 14, Figure 4, are shown flush with shoulders of weight 2, for necessary adjustment in the event of mishap.

Finally, Figure 8, depicts an end view of components in perspective.

1. A precision level comprising an arbor, enabling a drilled weight to rotate freely round its circumference, weight being fitted with twin grubscrews and twin angled needles, twin dials are employed, and spacing pieces are utilised.

2. A precision level as claimed in claim 1, employing a centrally circular arbor, allowing freedom of movement to said weight, (only moving part), remainder of arbor being squared to outer limits.

3. A precision level as claimed in claim 1 or claim 2, wherein aforesaid grub-screws are fitted flush into shoulders of weight, permitting counterbalance adjustments.

4. A precision level as claimed in claim 2 or claim 3, employing said angled needles affixed to said weight, to rotate through 360 degrees.

5. A precision level as claimed in claim 3 or claim 4, displaying aforesaid dials, facing outward from centre of unit, suitably engraved, enabling said angled needles points to indicate given angles.

6. A precision level as claimed in claim 4 or claim 5, having situate on either side of weight, spacing pieces for guidance purpose, plus again, one outside each inner dial, being both supportive and practicable, i.e. needle space.

7. A precision level substantially described in detail herein, with reference to Figures 1 - 8 of accompanying drawing.
