Specification of Letters Patent.,

Application filed `'."Iovemflier 30, 1908. `Serial'Nio. 465,122. `i

To all whom/it mag/lconcern:

Beit. known that I, VILLIAA'I' Po'r'rian', a citizen of the United States of America, an'd residing at New York city, in the county of 'Xen `Yorkand State of New ,York, have invented. certain new and useful Ilinprovements in Scribers, ofwvliicli the `following is a speciicat'onisuch 'as will enable those skilled in the art towhich .it a'ppcrtains to make and use the same. l 1

This invention relates-to tools andi the obect thereof is to provide an limproved scriber adapted for use bymechanics geiler-4 ally, but' particularly by carpenters andwood-workers; fa further obje'ct being to provide a device'of this classjwlich may also be used as aleompqass; a fu'rtherobject being to proiiide inein's whereby lead pen-U cilsof different shapes and sizes maybe rigidly held in the saidtool; a ,further 0bject being to provide means for adjusting.

one lg`-of. said tool longitudinally of the pencil heltl\`t'heein;, a further object being to provide the usual seriber leg, provided with a round, blunt end, as 'w'ell as, a supplemental leg contained therein anda Ypro- .vided with a pointed end, adapted. for use as a compass point or for guiding thc `tool moldings and otheij places prac-u in quirks, tieally inaccessible to the blunt end leg; a still further object being to so constructtlic said blifint end leg as to protect the pencil poiiit"`wlien not in use and a sti'll further object being to provide a tool of this cla'ssf which is simple in construction;jvhich cannot readily get out of order andrequirc repair, which is applicable to 'niany differ- ,ent uses Fand which is comparatively' inox? pensive ,I f

My invention is fully described in'the following specification, of which'the accompanying drawings forni u part, in which the'separatc parts are designated 'by the saine reference characters in each of tho views, and in which Figure l is a view of my scril'iei-in a closedposition; Fig. 2-is a. similar view thereof in a partially extended position, ready for use as a scribed; Fig. 3 Iis a vertical section taken centrally through the scriber and showing the parts 1n positionfor' useas a compass or as a sci'ibor, and Fig. t is a section taken onthe line/1 4 of Fig. 1. In the drawings forming a part of this application I have shown a scriber comprising a body` niember'a of metal bent to form a lead pencil recess a2 and th ends of the said metal plate be# ing continued outwardly to forni a supporting member a? for the adjustable lefrs b and c, the latter of which is contained within the foriner'in the ordinary use -ot' the tool.4

- The legs 'b and c have a threaded bolt d passing therethrough ,-and provided with a thumb-nut (Z2, s aid bolt'passingthrougha tool, and it will c seen that by rotation of the thumb nut d?, in either direction, the legs bfand'c are'lockedt, or released from the member a3. i

- Adjacent the pencil casing a2 is a slo4 e, in 'the' member athrough which passes a `pin or equivalent e-lconnecte'd with :if-.plate e3 which is forked as shown inFig. 4 to form a gripper for`the lead pencil, said plate e, pin e2 and forks being preferably .madeA integral and, because of the inclina- Ition of tlie'slot pressure upon the pointed end of the lead pencil f serves to force the., .forks of tho plate e2 into the, said pencil,

thereby locking the same securely within the recess z, but slight pressure upon the opposite end ofthe pencil releases it from the said plate a.

By reference to Fig. 3 it will be seen that :Patented Auf. 15,1911."

composed of a sheet 6.5 slot a* inthe supporting-member (L3-of .the j the leg c has "a pointed end c2 whereas the l leg has a blunt rounded end b2; said logs being also provided at the backs thereof f* with slots b and cifi'espectively, tliegfornicr of which is much loiigci than the latter, the

"object thcrcofbcing that, when, from the position of thc parts shown in Fig. 1, it is I -dcsired t'o employ the leg'c, all that is neecssary' is to loosen the tliumh nut cl2 and move the leg b upwardly into thc position shown,in Fig. 3, the elongated 'slot' b3 pcrmittiug this movement, andthe leg c is also carried4 upwardly in this movement into the position im'lieated in dotted lines in Fig. 3, at, which point it is stopped because of the shorter slot. c, the ond thereof coming int/o contact with the member a and thus the legs b and n are quickly-and easily separated.

By means of the slot. a* the legs b and c. are adjustable longitudinally of the pencil f whereby a grcatorangc of useof my tool results than if the said legs were pivotally as well to tho blunt end 'leg b as to the pointed end leg c and this adjustment also lxed,this range of use applying protection of-the 'pointe permits, Without movinvr the pencil f, the l end thereofgas is clearly shown -inIFign'L f While I have shown one form of ,locking device for the pencil, it will be obvious that many other forms thereof will su gest themselves in order to accomplish ti e desiredresult, and many changes in and modiliea- -tions of the form of construction shown,

with respect to thescriber proper, maybe made, Without'departing from thejspirlt'of this invention or sacrificing its advantages.

Having fully described my invention what I claim as new and desireto obtain'by Let- 4ters Patent, is

1. A device ofthe class described,colm-y pris'ing a body member, having a pencil therein, a Vpivot in-said body member, a leg mounted on said pivotfa supplemental leg 'on said 'pivot within said'yfirstv named leg,`

and clamping means' for Vholding said first named leg out of operative position and said supplemental leg in operative position.

2'. A device of the class described, comprising a` body member, .havingvapencil' therein, a 'leg pivotally mounted, on ,said body member and Aa plate provided with forks, adapted toengage said encil,fslidl Y ablv mounted on said bodymem er. ,n
