' LAYOUT APPARATUS Filed June 27, 1968 INVENTOR. f [Rani/(mask United States Patent 3,528,178 LAYOUT APPARATUS Fred E. Kunzler, 9027 149th St., Jamaica, N.Y. 11435 Filed June 27, 1968, Ser. No. 740,685 Int. Cl. G01d /00 US. Cl. 33-169 3 Claims ABSTRACT OF THE DISCLOSURE A measuring gauge having a vertical shaft for receiving a first hollow cylinder which slidably engages the shaft, and a second hollow cylinder disposed below the first cylinder on the shaft and threadably engaged to the first cylinder through a calibrated bolt. The second cylinder includes a vertical slot for receiving one of a plurality of different scriber extension linkages for measuring the dimensional properties of working pieces.

SUMMARY OF THE INVENTION My apparatus includes a vertical shaft having its bottom end secured to a horizontal base plate support. A first hollow cylinder open at both ends slidably engages the shaft and is movable up and down therealong. A second hollow cylinder open at both ends slidably engages the shaft and is also movable up and down therealong. The second cylinder is vertically spaced apart from and is disposed below the second cylinder. Manually adjustable means connected between the cylinders serves to vary the vertical separation therebetween. A scriber extension linkage is detachably securable at one end to the second cylinder.

In use, the cylinders are moved together along the shaft to a position which approximates a desired altitude for the linkage. The first cylinder is then locked in position, and the means is manually set to provide a vernier or exact altitude or elevation setting for the linkage. The second cylinder is then locked in position and the linkage can then be used with a scriber for the purposes previously indicated or indeed for additional purposes as desired.

BRIEF DESCRIPTION THE DRAWINGS In the drawings:

FIG. 1 is a vertical side view of my apparatus;

FIG. 2 is a view through 22 in FIG. 1;

FIG. 3 is a view similar to FIG. 1 but rotated 180 with respect thereto;

FIG. 4 is a detail view of one type of linkage usable in my apparatus; and

FIG. 5 is a detail view of another type of linkage usable in my apparatus.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT Referring now to FIGS. 1-5, there is shown a vertical shaft having opposite parallel fiat vertical sides joined by curved ends. The bottom end of the shaft is secured to (and can be integral with) a horizontal circular base disc or plate 12. Plate 12 can be placed directly upon a suitable horizontal support surface 14 or can be placed upon a first similar plate 16 of larger diameter resting on surface 14 or plates 12 and 16 disposed one below the other can be placed upon a second similar plate 18 of still larger diameter. Plates 12 and 16 can be secured together by means of a vertical hollow screw 20 threadedly engaging aligned vertical bores in both plates. Plate 18 can be secured to plate 16 by a solid screw 22 which extends through a vertical bore in plate 18 into the hollow of screw 20.

A first vertical hollow cylinder 24 open at both ends and having a central bore conforming to the shaft slidably engages the shaft and can be moved up and down to a desired vertical position and locked in position by thumbscrew 26.

A second hollow cylinder 28 having a like bore also slidably engages the shaft 10 and is vertically spaced below the first cylinder. Cylinder 28 can be locked in position by thumbscrew 30.

A vertical bolt 32 extends into threaded engagement with a vertical bore in the wall of cylinder 28 and extends upwardly through a horizontal slot 34 in cylinder 24. A knurled hollow horizontal wheel 36 is disposed in slot 34 and receives the bolt whereby manual rotation of the wheel adjusts the vertical separation between the cylinders as a Vernier adjustment which can be read on scales 38 and 54.

Cylinder 28 has a vertical slot 40 which can receive the vertical end leg 42 of any one of scriber extension linkages 44, 46, 48 or 50. The leg can be locked in any position in the slot by set screw 52 in any well known manner and the bottom horizontal edge of leg 42 can be suitably set on scales 54 and 38.

Linkage 44 has a bottom horizontal leg 56 having a lower horizontal edge aligned with the bottom of leg 42 with a scriber 58 having a fiat bottom surface coincident with this lower edge. Scriber 58 has two spaced apart forward prongs 60 and two side prongs 62.

Linkage 46 has the same general construction as linkage 44 except that a portion of the horizontal leg is downwardly offset as shown at 64. This oifset is necessary for direct reading by measuring under objects in contrast of linkages of 44, 46, 48.

Linkage 48 has a downwardly inclined leg terminating in a scriber 58 having a bottom flat surface to reach lower than ground level than 14. Linkage 50 has a horizontally extending leg terminating in an opening for receiving a bolt 68 which holds a T-shaped linkage 66 to the end of horizontal linkage 50. The surface of T-shaped linkage 66 can be used to measure angles of work pieces by moving the measuring gauge against the work piece so that the surface of linkage 66 can be adjusted by means of bolt 68 to define the angle of the surface of the work piece. The angle of the work piece can then be meas ured directly with a protractor or other conventional angle determining means from the surface of T-shaped linkage 66.

While I have described my invention with particular reference to the drawings, such is not to be considered as limiting its actual scope.

Having thus described this invention, what is asserted as new is:

1. A measuring gauge apparatus comprising:

a vertical shaft,

a fiat base plate extending horizontally and secured to the bottom end of said shaft,

a first hollow cylinder open at both ends and slidably engaging said shaft for upward and downward movement therealong,

a second hollow cylinder disposed below said first cylinder and open at both ends and slidably engaging said shaft for upward and downward movement therealong, said second cylinder including a vertical slot along its circumference parallel to the axis of said shaft,

a vertical bolt threadably engaged to the top of said second cylinder and extending through a portion of said first cylinder,

a positioning nut disposed within said first cylinder and threadably engaged to said vertical bolt for positioning said first cylinder with respect to said second cylinder,

means for locking said first and second cylinders to said vertical shaft,

a pair of scales disposed within said second cylinder for measuring the location of said second cylinder with respect to said vertical shaft,

scribe means demountably engaged to the vertical slot of said second cylinder wherein said scribe means comprises a linkage having a downwardly inclined leg and terminating in a horizontal flat surface having a scribe point on the end thereof and wherein said linkage additionally comprises a pair of side prongs disposed along the vertical sides of said linkage terminating in scribe points, and

means comprising a set screw coupled through said scribe means to said second cylinder for securing said scribe means within said vertical slot to said second cylinder.

2. The measuring apparatus as recited in claim 1 wherein said base plate comprises:

a first circular disc secured at its center to said vertical shaft,

a second circular disc having a diameter slightly larger than said first circular disc, and

a screw threadably securing said second disc to said first disc.

3. The apparatus as recited in claim 2 wherein said base plate additionally comprises:

a third circular disc having a diameter larger than said second disc, and a second screw threadably engaged through said first screw to secure said third plate to said second plate.
