SCRIBER Filed May 16, 1962 Fig. '2 2 ,Z4/ 4A F/g. 5 4 25 INVENTOR Char/es A. Leach United States Patent 3,145,473 SCRIBER Charles A. Lea-eh, R0. Box 1155, Tulare, Calif. Filed May 16, 1962, Ser. No. 195,953 Claims. (Cl. 33-153) This invention relates to scribers and more particularly to a scriber specially designed for use by floor covering craftsmen and the like.

For the benefit of those having little or no knowledge of hand tools and the like, let it be said that Websters Dictionary defines the scriber as A sharp pointed tool for marking off materia Although the scriber is more generally associated with the metal working and wood working arts, it has, of course, been adopted by other arts having need for a tool of this type. Unfortunately, there has been little if any real development done on scribes to better improve their use in any of the newer arts such as that followed by floorcovering craftsmen and the like.

Although I personally call this invention of mine a template scriber, I fully realize that the term template as so applied as not too well understood by those outside the art who may come into contact with the same, and I therefore drop the word template in this specification.

It is, therefore, an object of this invention to provide a scriber specially designed to overcome all of the objections the floor covering craftsmen have of the usual scriber now available.

Another object of this invention is to provide a scriber of the character described with a new and novel means of both removing and adjusting its needle points.

Another object of this invention is to provide a scriber of the character described that will stay in its set position once it has been adjusted to the same.

Another object of this invention is to provide a scriber of the character described that is rugged and therefore will have a long useful life even when given hard usage.

Another object of this invention is to provide a scriber of the character described that can readily be manufactured by any company having machinery adapted to the metal working arts.

Another object of this invention is to provide a scriber manufactured from readily obtainable materials of standard shapes and stock size.

Another object of this invention is to provide a scriber of the character described that has a new and novel means of providing its needle points to be affixed in any position within 360 degrees.

Still another object of this invention is to provide a scriber of the character described having spring loaded needle points.

Other and further objects and advantages of this scriber will be hereinafter described, and the novel features thereof defined in the appended claims.

Referring to the drawing:

FIGURE 1 is a side view of this invention, phantom lines show a typical adjusted position;

FIGURE 2 is a top view of this invention;

FIGURE 3 is a sectional view of this invention taken substantially along line 33 of FIGURE 1 as viewed in the position indicated by the arrows;

FIGURE 4 is an enlarged sectional view of one needle point mounting of this invention;

FIGURE 5 is a bottom view, looking upward of FIG- URE 4.

Similar reference characters refer to similar parts throughout the several views of the drawing.

Having reference now to the drawing in detail, there is generally indicated by the character a scriber comprising a star-shaped member 11 having eight equally spaced points 12 that are alternately bent at right angle to one 3,l45,4?8 Patented Aug. 25, 1964 manner as to place the sleeve 17 in the same plane as the' aforesaid sleeve 16.

A circular knurled edged nut 19 screwed on to that end of the headed screw 13 that projects outward from the center of the disk 15 securely holds this novel invention of a scriber together.

Looking again at FIGURES 1 and 2 of the appended drawing, it will be seen that the aforesaid tubular sleeves 16 and 17 are each provided with internal threads for the reception of the legs 2% and 21 each of which is identical in shape and size and which embodies an externally threaded upper end 22 and a lower end 23 having a recess 24 terminating in a circular depression adapted to receive the blunt end 25 of a needle point 26. The aforesaid circular depression is at an angle to the longitudinal axis of the leg in which it is formed as one can well see on examination of FIGURES 3 and 4 of the appended drawing.

Each of the aforesaid legs 20 and 21 is placed in a tube 27 having a compression spring 28 on the upper end thereof when this unique invention is assembled as one can readily see by examination of the appended drawing which also illustrates the fact that each tube 27 is prevented from slipping down off the legs 20 and 21 by reason of the angularly disposed needle point 26.

It is obvious from the above described construction of this invention that the needle sleeve or tube as it is herein called is entirely new and different from the set screw principal that is found in scribers now on the market. The method by which the needle points 26 are removed or their angular position in relation to each other is changed is obvious to anyone experienced in the art, however, for the benefit for those not so experienced let it be said that all that is necessary for one to do is to unscrew the headless set screw 29 that is in the upper end of the tubular sleeves l6 and I7 and which controls the length of the legs of the scriber by the distance in which the legs 20 and 21 are screwed into the aforesaid tubular sleeves.

The construction and method of point adjustment and removal of this novel invention of a scriber has now been described in detail and its method of use is so obvious to anyone ever having any experience with tools and or instruments that nothing more need be said concerning the same.

From the above description of this novel invention one can see that the aforesaid needle point 26 can be rotated in any position within 360 degrees and fully locked in any desired position. It is obvious that the compression spring 28 pressing downward on the tube 27 will bind the needle point 26 in what I call its socket (circular depression in the lower end 23 of the legs 20 and 21). To remove the needle point 26 one has only to grip the tube 27 and compress the spring 28 by moving the tube towards the spring. This action frees the needle point for removal and or replacement as one may desire.

From the foregoing it will now be seen that there is herein provided a scriber which accomplishes all of the objects of this invention, and others, including many advantages of great practical utility and commercial importance. As many embodiments may be made of this inventive concept, and as many modifications may be made in the embodiment hereinbefore shown and described, it will be understood that all matter herein is to be interpreted merely as illustrative, and not in a limiting sense.

What I new claim as my invention is:

I. A scriber of the character described comprising a star-shaped member having a plurality of equally spaced points each one of which is bent at right angle and diametrically opposite another one of the points, and a disk on each side of the said star-shaped member against which its points are in pressure contact, and means of adjustably holding the said star-shaped member and said disk together and a leg having a threaded upper end adapted to engage an internally threaded sleeve secured to each one of the said disks and a tube having a compression spring at the upper end thereof adapted to receive each said leg and extending downward, each leg having a recess in the lower end thereof in which there is an angularly disposed depression in which is placed the blunt end of a needle point which is both removable and adjustable.
