'Ihe' )resent invention relates to a framin g V measurement may be taken for a bra'ce l-n a tool, and bevel protractor; and has for its principal object to provide a structure of. corner, e 7 this nature which is eiilcientqm enabling one Figure 7 18 a transverse section taken sub! to obtain the angle of bevel for each end and at the same time obtain the length'of any brace, rafter purline, beam, strut, or the like, by adjusting the tool to the actual position of the proposed brace, etc. then trans 19 ferring the tool to the stick from. which the brace, etc. is to be cut by placing the tool on the stick and scribing, orjmarking-acrossthe ends. 7 Another important object of 'tlieinvention is to provide protractor headsrwhich may be adjusted'inone plane for plain work or may be adjusted in twio planes, 'orboth directions', for the purpose of marking jack rafters, hip and valley. rafters, oblique braces,,or braces which are to fit inbetween timbers that are warped, crooked, or twisted. Another object of the invention is to provide a special attachment with adjustable wings to replace one of the protractors for the purpose o'f marking braces to fit in corners, of any angle, acute or obtuse.

. Another important object of the invention is to provide a tool of this nature which is exceedingly simple in construction, easy to manipulate and adjust, reliable and efficient in use, not likely-to easily become out of .order, and otherwise well adapted to the purpose for which it is designed.

With the above and numerous other ob jects in view as will appear as the 'description proceeds, the invention resides in certain novel features of construction, and in the combination and arrangement of parts as will be'hereinafter more fully described and claimed. In the drawing:- a Figure'l is an elevation of the tool show ing the same used to take the measurementsfor a proposed brace between two angularly disposed members, 4

. Referring totlie drawing in detail it-will be seen that the shank of the tool includes a I pair-of rods "5' and6, one of which has a bolt 7 projected therethrough which extends through an elongated slot 8 provided in the other member. nut (not shown) associated therewith whereby the members 5 and 6 may be held in different adjusted positions in respect to each other so as to vary the length of the shank as may be desired. 'Itis preferable to'con struct the member -6 with longitudinally extending rectangularly disposed edge-flanges i0 in'between which received the-memer. 5. ijrnprotractor headll ispivoted on :the end ofthe member '6 by means ofa bolt 12 which'm-ay be tightened forholding the head 11 at different angles in respect to'the-shank. Another protractor'head 13 is pivoted on the end of the member 5 by means o'fa bolt 14: which mavbe tightened bymeans of the nut 15'. The protractor head 13is provided with pin extensions l5 disposed in opposite directions which rotatably'receive thesleeves 16*of a. astraiiglrt eclgegplate 1 7.1 Thus the plate 17 may be rotated in differenta ngljes;

in respect'to the head 13. A bolt 18 passes transversely through one of the sleeves 16" as is clearly shown in Figure 5, and the head thereof is rested in a seat 19 so as to frictionally engage the adjacentpin 15, so that by tightening'up on the nut 20, the bolt head 18 will bind into engagement with the pin-15, and hold the plate 17 at any desired adjusted angle.

y removing the bolt 14, the head 13 may be removed from the shank, and a protractor indicated generally by the letter A may be substituted therefor as is indicated in Figure (3. Referring particularly to this protractor A, itwill be seen that the numeral 22 indicates a shank which is provided with right angularly disposed flanges 23 at its longitudinal edges for straddling the shank, and particularly the member 5 thereof as is This bolt 7 hasa suitable clearly indicated in Figure 7', so that when the bolt 14 is placed through the opening in the member 5, and through the shank 22, said shank 22 is held in fixed alignment with the member 5. The shank 22 is provided with an elongated slot 24- cxtending longitudinally thereof. A pair of straight edge wings 25 are pivoted to the end of the shank 22as at 26. Links 27 are pivoted adjacent the'ends of the wings 25, and are provided with elongated slots 28 so that a bolt 29 may be passed therethrough and through the slot 24, so that when the nut thereof is loosened, the Wings 25 may be adjusted to different angles in respect to each other, depending upon the angle of the corner, such as is indi cated in Figure 6, and then the nut tightened, and thus the wings are held in this angle.

It is thought that'one example of the use of the tool will be sufficient to set forth its utility to those skilled in the carpenter art. As shown in Figure 1. the tool is placed in the exact position of the proposed brace or strut. The tool is then taken away and placed on the stick as is shown in Figure 2, so

i that by scribing along the straight edges of the protractors 11 and 13, the stick may be cut so as to form the brace or strut fortitting in the position of the tool as it is shown in Figure 1. 7 The adjustability of the plate 17 in relation to the protractor head 13 takes care of any bevel whichmay be provided in one of the members, and thus by placing the tool on both sides of the stick, this bevel may be cut on the brace or strut. The device is used in the same manner in connec tion with a corner as shown in Figure 6, eX- cept that the protractor 13 is taken off, and the protractor A substituted therefor.

With reference particularly to the straight edge 30 shown in Figures 8 and 9, it is desired to point out that the lower end of a jackrafter fits on the wall plate of a building, while the upper end of a jack rafter fits in the hip rafters. Also, the lower end of a jack rafter is at right angles to the wall plate, while the upper end of a jack rafter is at an angle with the hip rafter, both vertically and horizontally; therefore, while the.

able fastening device which may be passed through one of the slots 32'.

It 1s thought that the construction, utility, operatlon, and advantages of the invention wil now be clearly understood by those skilled in this art. The present embodi ments of the invention havebeen disclosed merely by way of example, and in practice attains the various features 7 of advantage enumerated as desirable in the statement of the invention, and the above description. It will be apparent, however, that numerous changes in the details of construction, and in the combination and arrangement of parts may be resorted to without departing from the spirit or scope of the invention as herein after claimed or sacrificing any of its advantages.

Having thus described the invention, what I claim'as new and desire to secure by Letters Patent is w A tool of the class described including an adjustable shanks, heads pivoted on the shank, means for holding the heads at different angles to said shank, a plate, means for rotatably mounting the plate on one of said heads, and means for holding the pl-ate'at different angles in relation to said last mentioned head, the axis of rotation of the platebeing in a plane at a right angle to the axis of rotation of the head on which said plate is mounted.

In testimony whereof I affix my signature.
