To @ZZ whom it may concern:

Be it known that I, JOSEPH UBERT DUBY, a citizen of the United States, residing at Longbr'anch, in the county ofvMonmouth and State of New Jersey, have invented certain new andv useful Improvements in'Garpenters Tools, of which the following is a full and complete specification, such as will enable those skilled which may be used as a trysquare, pitch-cut' square, hip-cut square, miter-square, and also for the purpose of drawing circles,.gaging lumber, making octagonal cuts, and for many other purposes; and with these and other objects in being the invention consists of a com` bination-tool of the class specified constructed as hereinafter described and claimed. l

In the drawings forming part of this specication, in which similar reference characters designate the saine parts ineach of the views, Figure 1 is a view ot' one side of my improved combination rtool or square; Fig. 2, a view o f the opposite side thereof; Fig. 3,y a vcross-section on the line 3 3 of Fig.A 1; Fig. 4.-, a diagrammatic view showingl the method of operating my improved toolv in forming rafterpitches and hip-cuts; Fig'. 5., a view similar to Fig. 4 showing the methodof operating my improved tool in gaginglumber; and Fig. 6,y

a view similar to Fig. 4 showing the method of operating my improved tool in'drawing circles. c y

In the practice of my invention I provide a tool of the classspeciied which comprises an' elongated base 7,.into which is set a metal plate 8, and jthe base7 is preferably com-v posed of twoparts, 7 a and 7b, and one of said parts-that designated by the reference character 7b-is one-eighth of 'au inch. narrower than the other part Y u 1 1 The front edgeof the'base7,"into which the plate 8 is set, is a straight edge, andone end of said base is formed at a right angle to said edge, as shown at 9, andthe other end is formed at an angle ofvforty-iive degrees'to said edge, as shown at 10, andthe last-named end constitutes the miter end of my improved square or tool.

The edge of the plate 18 opposite the back of the base 7 is cut out to form a :right angle at 11, which point is opposite, or nearly opposite, the longitudinal center of the base 7, and by cutting out the said edge ofthe vplate 8, as above described, the said plate is divided into two arms 8ft and 9, and the outer edge of the 'arm 8a is in line with the straight end9 of the base 7, and the outer edge of the arm 9a of said plate is in line with the miter end 10 of the base 7.

The inner edge 12 ofthe arm 9L of my iinproved tool is provided, on one side with an ordinary scale l13.representing inches andy parts thereof, and inl direct linewith the said edge 'of said arm 9a and adjacent to the base 7 said plate 8 is provided with a hole 14, which 1 to l2,incl'usive, and the spaces ofV which are irregular, as shown in Fig. 2, and the scale 16 is the rafter-pitch scale.. The

`said arm 81 of the tool is also provided with two rows of pencil-holes 17, arranged as shown in Figs. land 2, and on the side adjacent to the wider part 7 of the base 7 the outer row of these holes is provided ywith scalonuinf l bers 75, 1, 1%, 2, die., Aand the other row is provided with scale-numbers i, l, lfdtc.

On the side of thearmS opposite that shown in Fig. 1 the holes 17 inthe-inner'row are provided with scale-numbersV-, Si., 1g, 1g, &c., counting from the base 7 and the holes in the outer row are provided with scale-numbers 3 l 1%, 1%, dac., counting from the base 7.

'heY main object ofproviding the separate rows of holes 17 in the arm 8fv of the tool is to adapt the device for `use gaging timber,

IOC)

, of an inch wide.

and one method of using the device for this purpose is shown in Fig. 5, in which the reterence-numeral 1S designates a piece of lumber, and it' it be desired to gage this lumber into strips, as shown in the drawings, the narrower side 7 of the base 7 ofthe tool is pressed against the edge of the lumber and a pencilpoint passed through the holes 17successively, beginning with the hole adjacent to the base 7, and the tool is moved along the surface of the lumber, and the lumber will be divided into quarter-inch strips, and the result will be the same if either side of the tool be used separately in this manner, except that when the wider side of the base 7 is pressed against the edge of the timber the first division will be only one-eighth of an inch wide. By using the tool as shown at the left of Fig. 5 and then reversing th'e tool and using the opposite side against the same edge of the timber the spaces on the timber will be one-eighth The holes 17 may also be used for drawing circles, as indicated in Fig. G, in which case the tool is placed on a piece of timber 19 and a brad-awl or other device is passed through the hole 14, while a pencilpoint is passed through one of the holes 17, and the tool may then be turned in either direction, so as to form a circle, and the diameter of the circle will depend upon the hole 17 through which the pencil-point is passed.

In Fig. 4 I have shown at 20 a method for determining a rafter-pitch or pitch-cut, and in this operation the base of the tool is pressed against the edge of the timber 2l, the wider side of said base being down and the miter end of the tool being turned from the operator. In this operation the iirst line drawn at 22 will form an angle of forty-tive degrees, and then by turning the end of the tool adjacent to the operatoroutwardly, as indicated in dotted lines, a pitch-angle at 1G of various degrees may be formed, as indicated at 24 and 25, the scale 1G serving to fix the number of inches to the foot in the pitch or pitch-cut of arafteror rafters.

The method of operating the tool to determine a hip-cut is indicated at 26 in Fig. 4, and in this operation the position ofthe tool is reversed, the narrower edge of the base being pressed against the edge of the timber, while the miter end of the tool is turned in the direction of the operator. ln this operation the pitch of a hip-cut is determined at 27, and for this purpose the end of the tool opposite the operator is moved outwardly, as indicated in dotted lines, and thescale at l5, operating in connection with the edge of the timber at 28, serves to give the exact degree of the pitch of a hip-cut, the said cut being indicated by the various lines at 29.

From the foregoing description it will be seen that my improved tool comprises an elongated base or head having a front straight edge and provided with two arms which project from the front straight edge and are separated by an angle of ninety degrees, the inner edges of said arms ranging outwardly from a point adjacent to the middle portion of the front straight edge of the base or head, and said arms may be formed separately, if desired, instead of integrally, and the back of the base or head may be straight or of other form.

In Figs. 4, 5, and 6 I have only illustrated four of the methods of using my improved tool in order to accomplish certain results; but various other results may be obtained, as will be readily understood by any one skilled in the art, and my improved tool may be used for making octagonal cuts, mitercuts, and for many other purposes, the adjacent edges ot the arms 8 and 9 serving particularly for the purpose of making octagonal cuts.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
