1 Claim. (Cl. 33-170) This invent-ion relates to a marker and more specifically provides a height gauge.

An object of this invention is to provide a marker used on a height gauge wherein the height may be accurately and easily set.

Another object of this invention is to provide a marker used in a height gauge wherein the height may be adjusted accurately by the use of a vernier ad ustment.

A further object of this invention 1s to prov1d e a marker which is simple in construction, easy in manipulat-ion and inexpensive to manufacture.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, where n like numerals refer to like parts throughout, and in which:

Figure 1 is a side view of the marker of this invention;

Figure 2 is an end view of the structure of Figure 1;

Figure 3 is a longitudinal, vertical section taken substantially along section line 3-3 of Figure 2 showing details of the vernier adjustment;

Figure 4 is an exploded detail view showing the differt parts of the vernier adjustment;

Figure 5 is a transverse, top plan section taken substantially along section line 5-5 of Figure 3 showing details of the height gauge; and

Figure 6 is a transverse, vertical section taken substantially along section line 6-6 of Figure 3 showing details of the pointed marker.

Referring now more specifically to Figures 1 and 2 of the drawings, it will be seen that the numeral 10 generally designates a base having an upstanding standard 12 projecting upwardly therefrom wherein the standard 12 is provided with graduated markings 14 representing inches and fractions of inches of measurement.

A carriage 16 is slidably received on and surrounds the standard 12 and a carriage adjustment member 18 is slidably received on the standard 12 at a point spaced vertically from the carriage 16. A set screw 20 is threadedly inserted through one side of the carriage 16 for abutting the edge of the standard 12 and locking the carriage 16 in place. An upstanding threaded member 22 projects upwardly from the upper edge of the carriage 16 and projects through bifurcations 24 on one edge of the carriage moving means 18. A knurled nut 26 threadedly engages the threaded portion of the member 22 and is held captive between the bifurcated members 24, thereby moving the threaded member 22 upon rotation of the nut 26. A set screw 28 having a suitable knurled head is threaded through the side of the member 18 into engagement with the standard 12 whereby the carriage 16 may be moved in relation to the member 18 when the member 18 is secured to the standard 12 by use of the set screw 28. It will be understood that by rotation of the nut 26 with the carriage set screw loosened, the carriage 16 will move vertically in relation to the member 18 thereby providing a fine adjustment for the carriage 16. Obviously, by loosening both set screws 28 and 20, the member 18 and the carriage 16 may be moved along the standard 12 for a rapid and rough adjustment of the carriage along the standard.

Referring now specifically to Figure 3, it will be seen that the carriage 16 has a projecting portion 30 at one edge thereof and a strap 32 surrounds the projecting 2 portion and a sliding pointer 34. A set screw 36 is threaded in the strap32 and engages the projecting, member 30 for clamping the slida-ble pointer 34. in adjustable relation to the carriage 16.

As best seen in Figure 3, the carriage 16 is provided with a vertical bore 38 extending upwardly froman elongated notch 40 provided in one edge of the carriage'16. A shaft member 42 having a knurled gripping portion 44 at one end and a threaded portion 46 adjacent. its midpoint for engaging suitable threads in the bore 38. is positioned throughout the entire length of the bore 38 and extending across the notch 40. A vernier member 48 and a bushing 50 are rigidly secured to the shaft 42 below the threaded portion 46. by the use of a suitable pin 52. A suitable vernier scale 54 is positioned along the lower periphery of the vernier member 48 for a purpose described hereinafter. A vertically movable member 56 is non-rotatably secured to the carriage 16 and vertically .slidable in the notch 40 about the shaft 42, and a coil compression spring 58 is positioned between the slidable member 56 and the upper surface of the notch 40, thereby urging the movable member 56 upwardly towards its extreme upper position against the nndersurface of the vernier member 48.

As best seen in Figure 4, the movable member 56 has a vertical index line 60 to be selectively aligned with the vernier scale 54, and a horizontal index line 62 to be selectively aligned with the graduated markings 14 on the standard 12. It will be noted that the movable member 56 is provided with projecting lugs 64 which accommodate the index line 62 and project inwardly from the notch 40 into sliding engagement with the periphery of the standard 12 and project into the viewing window 66 of the carriage 16.

The operation of the device will be readily understood. With the base 10 setting on a suitable surface, the pointer 34 and carriage 16 are adjusted vertically of the standard 12 by loosening the set screws 28, and the members 16 and 18 are moved to the desired height and the set screw 28 is tightened. The index line 62 is then brought into alignment with the desired graduated marking on the standard 12 by manipulating the knurled nut 26, thereby giving a fine adjustment to the carriage 16. The pointer 34 may be extended by loosening the set screw 36 and moving the pointer 34 in an obvious manner, thereby giving the pointer 34 a great degree of horizontal adjustability. As shown in the drawings, the upright is graduated in .025 in., which is found on all conventional height gauges. The vernier member 48 is graduated so that one complete revolution of the knurled knob 44 causes the movable member 56 to move exactly .025 in., or from one graduated line on the standard to the next graduated line. The graduations 54 on the vernier scale are each .001 in., thereby providing an adjustment of the pointer 34 to the nearest .001 in. If it is desired to set the gauge at a height of 4.068 in., the knurled knob 44 is turned until the .018 in. graduation is in line with the index line 60, and the index line 62 is then brought into alignment with the 4.050 in. on the standard 12 by manipulation of the knurled nut 26. Adding the 4.050 in. and the 0.18 in., the height of the pointer 34 may be set or determined.

The various elements of the device may be made of any suitable material, and the threaded portions 22 and 46 must be accurately formed for ease of operation, and in the case of threads 46, for accuracy of operation. This vernier adjustment for the height gauge provides a quick and accurate method for setting the gauge at a predetermined height or measuring the height of some article as desired.

From the foregoing, the construction and operation of the device will be readily understood and further explanation is believed to be unnecessary. However, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the appended claim.

What is claimed as new is as follows: Y A marker comprising a base member, a standard on said base, graduated markings on said standard, a carr-iage vertically slidable onsaid standard, means on said carriage forming a pointer, means to secure said carriage in adjusted position on said standard, said carriage having a recess therein a movable member in said recess, an index line on said movable member, means to adjust Isaid movable member on said carriage, said carriage having a bore opening into said recess, said means to adjust said movable member including a rotatable shaft, a vernier member having a Vernier scale thereon secured to said shaft, said shaft being threaded in said -bore in said carirage, said index line being in alignment with said Vernier scale, a spring continuously urging said movable member toa raised position, said spring yieldingly engaging said movable member and said carriage, said movable member being vertically moved against said spring by the rotation of said shaft wherein 'the length of movement may be determined by viewing the relationship of the index line and- Vernier scale, and an index line on said movable member in alignment With said graduated markings, said movable member being movable a distance equal to the distance between the graduated markings.
