The manner: graduating dial plate 3 and the eonction with the same of the pointer are fractures of soy invention As indicated more particularly in Fig. 8, I prefer to graduate the dial plate adjnrout to its pei-ipl r into degrees hv term, as shown at 1.9, hulivuhng: figures or indieiu 19' preferably being plaeed upon the dial plate adjacent to these division marks. As shown in the drawings, I have two positions marked 'iero, with the degree marks running by tens from zero to 90 degrees in each direction. The pointer memlu-r 9 is triangular in shape, that is, it has striiighr. edges 20 and 21 upon its sides, which edges are radial, or would pass, if? prulnng'ed, through the axis of Y0- tu'tio-n of the pointer at the center of dial 8. The (listener hetween the outer ends of sides 20 and 21 of the ointr is the same as the distance between t e indicating climacters we, and the parts sire. so arranged that when the pointer is positioned with the two the pointer nna Zero nm in nlinemont with its cages 30 and 2], blade 5 is exactly parallel to stock 1. The edges of pointer 9 are preferably beveled as shown, and .mnrks'lt) are rat ial tn the center of rotation of the. pointer. When pointer 9 is moi ed to the left, referring t Figs. 1 and 8, until the left'handedge 20 ,of the pointer comes into nlincmnnt with the thirty degree graduation oftl e dial to the left of the dinl, referring to Fig.8, the edge 22 of blade. 5 makes an angle of thirty degrees with the upper edge of, stnelr] and the edge, .23 of thehlnde makes annngle of thirty degrees with the lower edge of the stock 1. right until the right hand ei'ige 21 of the pointer mun-s into nlimement with, for 'example. the thirty degree. mark, that portion of edge 23 of lglnde :3 which ppenrs as the upper part Ar the blade in Fig. 1, will make an angle of thirty '(lcgre-z-s with the lower edge of the stnzh', and thnt portion 'ufrdge 22 of the blade whirl: is shown below hr slocl; in Fig. i, will make. an angle rat-thirty degrees with the upper edge of the stock, and rurrespondingly, he pointer set in :ilizismem with {my other of the graduation niurlrs l9. 4

The inne in ring; are. also divided by equally spaced mil grnduatious .24, the grndu'ations 0 each ring extending from the inner to'the outer circle thereof and the marks 24 of each circular series being ten degrees apart. The g 'acluntions 24 of each ring are one degr'ee in ndrunre of the corresponding graduatlons of the next smaller ring. That is, the marks of the smallest ring a l'spresent one degrne 11 degrees, 21 degrees, etc., the grnduations of ring 7/ represent 2 degrees, 12 degrees, 22; degrees, etc., the graduatinns of ring c rep#. resent 5' degrees, 13 degrees, 23 degrees, etc., and the same for all of the circles in. both directions frnm the -ro marks.

the figure l lu ing nuu'lged within the. innernmst. ring 1- wrrespz'nuh-ng to the :smallest ring a of the dial. Au'urdmgly, when it s desired to get a. reading of one. degree in either d rection, the edg 10 or ill of tho T pointer member is muved slightly from the zero position until-the edge nriuucnt "the figure l mines into line with the ncnrst graduation upon the dial. ll" it is desired to get :2 reading: of, for example. :23 degrees in either direction, the. corresponding-edge-of the pointer is brought into lin'e' with-the grxulruitinn ndjm ent. the. llglll. 20 upon the. pk' riphery oithe' dial and the pointeristhen moved a slight further distance until .the same edge of tho pointer ndjncntthe figure 3, upon the pointer, isjhruught into :dinement with thefirst mark in the ring 0 of the dial. y

If greater accuracy in reading; the devioe is desired, the construction shown in Fig. 9 may he employed, in which pointer 9 is pmvigled with a. series of small holes 25 there For some uses, a construction such as that:

shown in Fig. might be preferable, this tin-ore illustrating a construction in which the dial member 8 is. of a much more considerable thickness than the dial 8, shown in the previous figures, dial member 8 being graduated upon its eripher in the same manner as has been escribe in connection with the marking upon the face of the dial 9, of Fig. 8. In this case, the ointer memlwr 9 has an extension 28 in t e form of a portion of a hollow cylinder which rests upon and is adapted to rotate around the periphery 29 of member 8. Such construction is of advantage where the reading oi. the angle is more conveniently made from the edge and where the added thickness of the dial member is not objectionable. In this case, of course, the series of holes and it; with the corresponding pin 27 may :also be used if desired.

When, for an reason, it is desired to r0 tale blade 5 wit tout moving the pointer, the enlarged )ortion 7 of slot 6 of blade 5 may be broug t into position surrounding the boss 11 of the pointer. Preferably blade 5 is provided with a beveled end 30 as shown, which is formed at degrees or at; any de: sired angle with the edge 23 of the blade. Also preferably the blade 5 carries a small graduated scale 31 which is slidably mounted adjarmit one edge as the edge 23 of the blade. This small scale is slidably mounted in any desired manner as b the dove-tail mmstrurtion shown at 32 in ig. 2, and may be extended in either direction beyond the end of blade 5. This small scale maybe ex tended into conical or angular holes of small s-ctiou into which blade 5 could not pass.

Preferably my device is provided with an attachment whereby the straight edge 33 may be adjustably secured to stock I. A s rew 34 having a head 3:) provided with two plus 26, preferably tapered, may be extended through the upper and lower members of stock 1 and a corresponding opening in straight edge 33, the nut 37 being mounted upon the upper screw-threaded periphery of screw 34 to clamp the parts in adjusted position. a bracket 38 upon the face oi stock 1 having a circular tlanue 39 extending above the annular flange 40 upon nut 37 to hold the latter in po ilion. ,lllade or straight I may he graduated as shown at 43, the

inner edgeof blade 33 when the 'sitizimed at right angles to the of calipers, blade 5 and to, said dial'member bein edge 33 may be provided with two pairs of holes 41 atright angles with each other through either pair of which the prongs 30 of head 23.? may be passed, to secure blade 33 in position, either at right angles to stock 1 or parallel thereto. ()r, of course, any number of holes 41 may be provided, spaced in any desired manner, so that blade 33 might be, given any desired angular position with as" ct to stock L vVhen blade 3;} is positioned parallel to stock 1, beveled edge 42 of blade 33 is positioned across stock 1, and either edge of blade 5 may be brought in contact therewith to quickly position the blade at whatever angle is represented by edge 42, without setting the protractor. When straight edge 33 is set at right angles to the stock, the tool becomes a square The lower edge of the upper face of stock graduations beginning at a point in linewith the same is postoclt. By this meansthe'deviee may be used as a pair lade 33 being adjusted into contact with the opposite sides of any object to be measured, and the, distance between the same read on scale 43. If scale 48 is used, dial 8, which is preferably beveled adjacent its lover edge, should be cut back a slight distance from its lower edged permitthe reading of scale 43.

It should be understood that m inven tion is not limited to the exact tletai s of con struction shown, but that my invention is as broad as is indicated by the accompanying claim Having now described my invention what I claim as new and de ire to protect by Letters Patent is:

1. In a device of the character described, the combination with a dial member, of a pointer mounted concentrically with said dial member, to rotate withi'respeet theredivided into tens of degrees along each u. ienconeentric arcs struck from the axis of said pointer as a center by short lines ii'iterseeting said arcs, each of said lines being at an angular ad Vance of one degree beyond the adjurent de g'reo line of the nearest smaller are said dial member also carrying indicia adjacent the degree lines of the outer are, and said pointer carrying: indiria at. radial distances f m its axis (gm-responding to the radial position ofsaid degree lines of the arcs of said dial member other than said outer are, said indicia bein adapted to indicate tho angular position of Stlld pointer when the same is rotated.

2. in a device of the character described, the mmliination with a dial member of a pointer mounted concentrically with said dial m mber to rotate with restart. thereto. said dial member being divided into units
