RULE.
Application filed June 14, 1912. Serial Nol 703,602
To all whom it may concern:
Be it known that 1, Louis Vooounnnrrnn, a subject of the Emperor of Germany, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Rules, of which the following is a specification.
My present invention relates to an improved foldin rule, having an adjustable graduated slide for giving measurements which are not conveniently obtainable by the use alone of the folding sections of the rule. Tits constructive features and advantages will be understood by those skilled in the art from the following description, in connection with the "drawings which show only one of the specific forms which my invention may 1L; ":e. In them Figure 1 is a plan View of my improved rule; Fig. 2 is a section on the line 22 of Fig. lon a larger scale; Fig. 8
i "a section on the line 3-3 of Fig. 1 on larger scale; Fig. 4 is a section on the line .l.4: of Fig. 1 on larger scale; Fig. 5 is a view of the inner end closure piece, and Fig. 6 is'a view of the outer end closure piece.
I will now describe the devices of the drawings, reserving it to the claims to point out the novel features and to define the scope of the invention, it being understood that the claims will be given the due range of equivalents to which they may be entitled in view of the art.
In the drawings A is a folding rule consisting of sections 1- 1 pivotally connected at 2 in any well known or preferred manner, so that the fraction of a unit by which their ends extend beyond said pivots is uniform.
3 is an adjustable graduated slide on the first unit section of the folding rule. The
first unit on. this slide is located at a dis tance from the distal end thereof which is the complement of the aforesaid uniform distance that the pivoted ends of the fold ing sections extend beyond their pivots. Then the graduations on the slide continue upwardly, 1, 2, 3, etc, as on the first foldin section.
ig. 1 shows the rule in operation to determine the distance between two points. The reading is obtained by adding together the highest unit, namely 6, shown on the main rule, and the highest unit, namely 3, shown on the slide, and then adding to this again the fraction of the reading shown between the last named unit of the slide and the end of the main rule.
The slide 3 has over-cut sides coiipcrntmg with the under-cut sides of a longitudinal groove in the folding section of the rule. The slide is located so as to partake of the graduation marks of said folding section, but so as not to interfere with the numerals that designate the units.
l is a leaf-spring having a free portion 4 on the under side of, the slide 3 to bear Wieldingly against the bottom of the groove, and thereby frictionally hold the slide in any given extended position. The fixed end of this spring projects up through a slot or hole in the slide and thence is bent downwardly again and driven or anchored in the top of the slide. In this way a projection 4* is conveniently formed on the top of the slide for adjusting it endwise.
5 is a piece of sheet metal acting as a closure for the one end of the groove in the folding section and as a stop for the slide. Fig. 5 shows this piece flat before it is clamped on the end of the folding section. The prongs 5 project down into the wood above and below and secure the piece 5 in place. Fig. 6 shows in flat condition another piece 6 for the other end of the rule section having prongs 6. This piece is applied in the same way as the other piece 5, except that it does not act as a stop because it has a properly shaped opening 6" through it, permitting the slide to pass unobstructed.
Such changes and modifitmtions as can be made in any of the foregoing without departing from the spirit and. scope of my improvements are assumed to be covered hereby.
Vhat I claim is:
1. In combination, a folding rule in pivotally connected sections having consecutively numbered graduatit/ns, an ad ustable graduated slide on the first unit section of said rule, the fraction of a unit by which the pivoted ends of the sections extend beyond their pivots being uniform and a predetermined portion of a scale unit, unit graduations on the adj ustable slide beginning at a distance from the distal end thereof, that is a complement of the portion of the unit distance of the pivot end extensions of the rule sections, said lattergraduations corresponding to and being consecutively numbered like those on the adjoining section of the rule.
2. In combination, a folding rule in pivotally connected sections, an adjustable I thereon, 2L spring, interposed 'between the side of the 'li end sectioii of said .rulegand a. spring having zen outer end anchored in the outer side of the slide where it forms a finger-engaging projection 130 said spring t ence projecting through the a free portion onthe inner in presence the operation of the slide,
slideand hav'ng e which bears against the groove.-
Y 3. A rule comprising a main portion and an adjustable portion slidebly mounted main portion "and slide and projecting through the latter, forming a finger-engaging projection, and means located in the path of said rojeotion for limiting the move- 5 ment of t e slide in one direction.
In testimony whereof I afix my signature of two witnesses. LOUIS VOGGENREITER. Witnesses: I
