GABPEN-TERS CMBINATION TOOL.

Application led April 29, 1926. Serial No. 105,491.

e This invention relates to combination tools.

of that type employed by carpenters; and has for one of its objects to improve and simplify the general -construction of tools of this character and to provide one that may be convenientlyused as a saw, rule, square, try-square, miter square, sliding T bevel square, plumb, level,depth gage, marker, scriber, screwdriver, wood chisel, and pencil holder. v

With the above and other objects in view, the invention consists of the construction, combination, and arrangement of parts hereinafter 'fully described and claimed, and illustrated in :the accompanying drawings, wherein:

Corresponding and like parts are referred to in the following description `and designated in the several views of the accompanying drawings by similar reference numerals.

Fig. 4 is a view of a fragmentary portionof `the tool illustrating the same 'adapted- The combination tool comprises a saw blade 1, a handle 2, and a square 3.

The saw blade 1 is of the usual construction with the exception that its top or plain edge 4 and front edge '5 are graduated asshown at 6 and 7, respectively.

The handle 2 which may be made of wood,

`metal or other suitable material, is square and may be secured to the saw blade 1 in any suitable manner. The top side 8 of the handle 2 is in longitudinal alinem'ent with the top edge 4 of the saw blade 1. The bottom side 9 of the handle2 is located below the bottom or toothed edge of the saw blade 1. rlhe -front side 10 of the handle 2 is at right angles to'the top edge 4 of the saw blade 1 to provide straight edges adapted to cooperate with said top edge to form a square. To permit it to be readily grasped,

the handle 2 is provided-with an opening 11 and a recess 12, the latter being located in the rear side 13 of the handle. A spirit level 14 adapting the tool for use as a level, anda spirit level 15 adapting the tool for use as a plumb, are arranged at right angles with relation to each other and are suitably n fixed .inopenings 16 and 17, respectively, in the handle 2. The spirit level 1 4 is arranged parallel to the top side 8 and bottom side 9 lof the handle 2, and the spirit level 15 is arranged parallel to the front side 10 and rear side 13 of the handle. The top edge 4 of the saw blade 1 and top side 8 'of the handle 2 may be, as shown in Fig. 3,

held in contact with the work when the tool is beingemployed as a level. It desired any of the other sides of the handle 2 may be held in contact with the work'when the tool is being employed as a level. The top edge 4of the saw blade 1 and the top side 8 of the handle 2 orI any of the other sides of the handle may be held in contact with the work when the tool is being employed as a plumb. The handle 2 is provided at one of its lateral sides with a clip or other suitable holder'18 for a pencil 19, and in said side with a pocket 20 for the reception of a screwdriver 21 and a work chisel 22. The chisel 22 is provided with a socket 23 for thel reception of the shank ofl the screwdriver 21, as shown by dotted lines in Fig. 1, whereby to. permit these parts to be compactly assembled for storage in the comparatively short pocket 20. 1

' The handle 2 is provided with, a vertical screw 26 and which when not in use is lothe st blade 30 is secured at right an cated wholly within the recess 24 with its front side in alinement with the front side 10'of the handle 2. lThe square 3 comprises a graduated stock 27 havi a pocket 28' and slot 29, and a graduated ,b ade 30 having a slot 31 and a beveled end 32x, said end being preferably arranged at an angle of 45. One

side of the stock 27 is solid and in the other side thereof the slot 29 is formed. When the square 3 is not in use, the blade 30 is located wholly within the pocket 28 and is secured therein by a thumb-screw 33 which has threaded enga ement with the solid side of the stock 27 an passes through .the slots i 29 and 31.

The withdrawal of the set-screw 26 from engagement with the handle 2 and the loosening of the thumb-screw 25 rmit the square 3 to be swun on the thum -screw 25 as apivot into di erent angular positions with respect to the top edge 4 of the saw blade l and the top side 8 of the handle. To permit the square 3 to be swunginto and supported in a 45". position with respect to the to side 8 of the handle 2, when it is desire to use the tool as a miter square, the top ed vof the rear wall of the recess 24 is beve ed oif at an angle of 45 as shown at 34. After the square 3 has been swung into this position, as clearl shown in Fig. 4, the thumb-screw 25 is tlghtened to hold it against casual movement. With the uare 3 in this position, the top edge 4 o the saw blade 1 and the adjacent edge of the stock 27, or the top side 8 of the handle a 2 and the adjacent edge of the stock 27,

ma be used in forming the initer. Y

y swinging the part 3 into and securing it in an upwardly extending ri libangular position with respectto the top e ge 4 of the saw blade l and the to side 8 of the handle 2, as clearly shown in ig. 5, the tool will be ,adapted for use as a T bevel square. When the tool is to be used for this purpose the g es with reslpect to the stock 27 and with portions t ereof rojectngbeyond oppositeedges of .v By arranging and securing the stock 27'in an angular positonoi 45 with respect to the top side Softhe handley2yend by arranging vand securin the blades`30 in an upwardly extending right-angular posi.

tion withrespect to the stock 27, as shown .in Fig. 6 the tool will be adapted for use "as a dou le sliding T' bevel square.vr The tool `can also be adapted .for use as a de th gage and whenl it is to be used for t is purpose the stock 27, if not already in such position, is'swunginto and secured in de pendin position within the recess 24 and the bla e x30 is swung into and secured in a position at an angle with respect to Vthe stock 27,as shown in Fig. 7.- v v The thumb-screw 25 is detachably connected to the handlev2, andfdue thereto the eqllilre 3 may be removed fromv the handle w never it is desired.' o use it independ ently of the handle and saw blade 1.

As shown in Figs. 8 and 9 the tool may be provided with markers 35. These parts are of .aU-form to permit them to straddle the graduated to edge 4 ofthe saw blade 1 and are adjustab y secured to the saw blade by set-screws 36. Any number of markers may be used, the number used de' nding solelyr on the nature of thework to 'e done, as for instance in laying out a 17/8" joist with 16" centers two markers would be used. One of the markers would be placed at 1417/8 and 35 the other at 16" from the front edge 5 of the saw blade 1, and after they. have been se cured in place by the set-screws' 36 the first mark would be made at the end of sill. After this has been done the tool is grasped in the right hand and placed nearly flat on sill with front edge 5 of saw blade 1 in alinement with the mark. By imparting a small movement to the tool at right-hand both marks for the joist will be given.

As shown in Figs. 10 and 11 the tool may be provided with a scriber .37 4which is pro vided with a slot 38 to permit it to be a plied to the graduated top edge 4 of t e saw blade 1. The scriberis provided with an adjustable marking screw 39 and a retaining screw 40, the latter removably securing the scriber to thesaw bladervl.'

From the fore oing description, taken in connection with t e accompanying drawings, the advantagesof the tool will be readil apparent to those skilled in the art to whic it appertains. While I have described the manner in Iwhich the invention is adapted to be used, together with the device `which I now consider to be the best embodiment. thereof, I` desire to have it understood that' the device shown is merely illustrative, and 1 'may bemade when de- 1`15 and one lateral si e-ther'eof, the' top edge of mr J the rear wall of the recess being beveled oi at an angle of 45, a aduated stock pivotedat one end within t e recess, andi/a grad, uated blade adjustably secured to the stock. In testimony whereof I aiiix my signature.

THOMAS M. SHEABER.
