Application filed December 7, 1906. Serial No. 346,73 L

To rzZZ whom it may concern:

Be it known that I, IIARRY BROWN, a citizen of the United States, residing at Buffalo,

in the county of Erie and State of New Y ork,

. character whichcan be compactly folded, if

desired.

In the accompanying drawings: Figure 1 is a side elevation of one form of the tool, showing it open; Fig. 2 is a similar view of the tool as it appears when folded. Fig. 3 is a top plan or edge view of the folded tool. Fig. 4 is a cross section in line 44:, Fig. 2. Fig. 5 is a perspective view of the protecting cap or shield of the foldable rule extension. Fig. 6 is an enlarged longitudinal section of the jointed portion of the tool. Figs. 7 and 8 are side elevations of a modified construction of the tool viewed from opposite sides. Fig. 9 is a top plan or edge view of the same. Fig. 10 is a front view-thereof.

Similar letters of reference indicate corresponding parts throughout the several views.

The tool shown in Figs. 1 to 6 inclusive comprises a pair of jaws or limbs A, A forming the jaws of the tweezers and composed of steel or similar elastic material. These jaws are suitably spaced and secured together at their rear ends and normally di,

verge toward their front ends, as is customary in tweezers, so that when closed and released they spring to their open position. The front portions of the jaws are preferably tapered forwardly and scored or roughened on their inner sides, as usual.

In the construction shown in the drawings,

the rear ends of the jaws are separated by a space-block b arranged near one edge thereof, as seen in Fig. 6. One of the jaws, say the jaw A is provided on its face with suitable graduations c forming part of a rule or The other part of the rule is carried by a foldable limb or' extension D preferably pivoted between the rear ends of the jaws by a transverse pin d, so that it can be folded between the jaws, as shown in Figs. 2 and 3,

or unfolded as shown in Figs. 1 and 6. On the face of this extension are arranged graduations d which form continuations of those on the jaw A, when the extension is un- The rule illustrated in the drawings is graduated in accordance with the ordinary compositors rule, but the graduations may obviously be changed, as desired, without departing from the invention. The space block b also serves as a stop or shoulder for limiting the unfolding movement of the extension D beyond a position in line with the graduated jaw A In order to retain the jaws in their closed position whencarried in the pocket and also prevent injury to the fingers by the pointed ends of the tweezers, the extension D may be provided at its free end with a cap, shield or hood F adapted to cover or inclose said points. The cap shown in the drawings consists of a U-shaped strip of metal or other suitable material which extends around theends and sides of the tweezer-jaws and is secured at its ends to the free end of the extension D which latter when folded terminates somewhat short of the ends of the jaws, as shown in Fig. 3. The cap extends laterally beyond the sides of the extension so as to receive the tweezer-jaws when pressed together, as shown in the last mentioned figure, and its contracted inner portion is provided withnotches or recesses f which receive the front ends of the jaws and allow them to enter the cap when the tool is folded.

Suitable locking means may be employed for retaining the cap upon the jaws, the lock shown in the drawings consisting of a pair of teats or projections g formed .on the inner sides of the cap by indenting its side walls. These projections are so arranged that the edges of the tweezer-jaws engage behind them as shown in Figs. 8 and 4, the jaws being pressed together sufficiently for this purpose in passing the cap over them.

The jaw A is preferably provided on its face at'the first or zero graduation of the rule with a gage-stop h against which a card or other article may be placed in measuring the printed matter thereon. The members A, A not only form the jaws of the tweezers but also serve as a case or sheath for the rule-extension D when folded, while the cap carried by the extension forms a protector for the pointed ends of the tweezers and also a holder for keeping the jaws contracted when the tool is carried in the pocket or used as a short rule. Aside from its function as a protector, the cap serves as a locking or retaining device for reliably holding the rule extension in its folded. position. if desired, this cap or protector may be omitted, as shown in Figs. 7, 8 and E). In this case, the rule extension D is pivoted to fold between the jaws of the tweezers, as in the construction first described, and is provided at its free end with a hook or spring clasp i adapted to engage over the edge of one of the jaws, to hold the extension against the same. This construction, while retaining the extension in its folded position, permits the tool to be used as a pair of tweezers in that position of the extension. In the drawings, the extension 1) is indicated by dotted lines and it will be understood that the same is to be graduated like the extension 1) of the tool shown in Fig. 1. This modified tool also has a gage stop 71, similar to the stop it of the construction first described. If desired, the ungraduated jaw A of the tool may be scored, as shown at 7', to form a file.

I claim as my invention. I

l. A combination tool, comprising a pair of tweezer-jaws, one of which is graduated to form a rule, an extension pivoted to the rear ends of said jaws to fold between the same and having graduations forming a continua tion ofthose on said jaw and a retaining de vice carried by the free end of the extension and adapted to en age with the tweezers, substantially as set forth.

2. A combination tool, comprising a pair of elastic tweezenjaws, one of which is graduated to form a rule, a foldable extension pivoted to the rear ends of said jaws to fold between them and graduated to form a continuation of the graduated jaw, and a pro-- tector carried by said extension and arranged to cover the front ends of the tweezer-jaws when the extension is folded, substantially set forth.

3. A combination tool, comprising a pair of tweezer-jaws, one of which is graduated to form a rule, a graduated extension pivoted to the rear ends of said jaws to fold between the same, and a cap carried by said extension. and extending laterally beyond the sides thereof to receive the front ends of the jaws located on opposite sides of the extension when the latter is folded, substantially as set forth.

4. A combination tool, comprising a pair of tweezerjaws, one of which is graduated to form a rule, a graduated extension pivoted to the rear ends of said jaws to fold betweenthe same, and a cap carried by said extension and adapted to inclose the front ends of the t'weezer-jaws, the body of the cap being wider than the thickness of the extension and its contracted inner portion being provided with notches which receive said jaws, substantially as set forth.

5. A combination tool, comprising a pair of tweezer-jaws, one of which is graduated to form a rule, a graduated extension pivoted to the rear ends of said jaws to fold between the same, and a cap carried by said extension and provided on its inner sides with locking projections behind which the tweezerjaws are adapted to engage, substantially as set forth.
