TRY-SQUARE.
Specification of Letters Patent.
Patented Apr. 13,1215.
Application filed March 21, 1914. Serial 1T 0. 826,230.
To all whom it may concern:
Be it known that I, ELL/[ER W. CoKELY, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Try-Square, of which the following is a specification.
This invention relates to try square so constructed that it is available for a great many more uses than the ordinary try square, one object of which is to enable the square to be laid upon the surface of the ma terial and against either edge thereof, and lines may then be drawn on the face of the material and on the edge of the material which will exactly intersect each other without moving the square.
Another object is to provide a back blade on the main blade which will furnish a broad bearing surface to rest against the material and hold the try square from falling over sidewise, and to hold the plane of the tongue of the try square perpendicular to the surface against which the back blade rests and thereby obtain a greater ease and accuracy in the use of the tool, this feature also enabling the try square to be used on materials having an edge of irregular cross section such, for example, as molding, the wide back blade being adapted to extend sufficiently over the edge of the molding to lie with a line of contact with the outermost edge of the material, even though such outermost edge be in a different plane from the surface against which the tongue of the try square rests.
Another object is to enable the tool to be laid on a substantially horizontal surface in a position for marking or measuring thereon, without requiring the tool to be held by hand in such position, means being provided on the tool for holding it in such position when at either side of the material, that is to say, with either side of the tongue up.
A further object is to so construct the tool that it may be used in marking a long miter. The tool is also adapted to lay out a Dutch miter and straight or angular marks.
A further object is to enable the tool to be used as a gage for drawing a line parallel with the edge of the material, the tool operating from either edge of the material for this purpose.
While I have mentioned some of the uses of the invention, others will suggest themselves to those skilled in the art.
Referring to the drawings: Figure 1 is a perspective of the tool. Fig. 2 is a side elevation. Fig. 3 is a front elevation. Fig. 4 is a plan View of what is shown inFigs. 2 or 3. Fig. 5 is a perspective view of the corner portion of the try square, showing a modified form. Fig. 6 is a perspective view of the corner portion of the try square, showing a modified form.
The tool comprises a main blade 1 with a tongue 2, formed preferably integral therewith and projecting at right angles thereto and inthe same plane therewith. Secured to the back edge of the main blade is a back blade 3 which projects from either side of the main blade and is preferably slightly offset such that the width of one side, as indicated at 4, Fig. 1, is slightly wider than the other side, as indicated at 5. For eX- ample, the width of the side 4 may be t11s inches and the width of the side 5 may be gths inches, these proportions being suitable for the sizes of lumber usually employed in inside finishing or cabinet work. The plane of the main blade 1 and tongue 2 is at right angles to the plane of the back blade 3. The upper edge 6 of the back blade 3 is at right angles to the side edges 7 and 8 of the back blade and the edge 6 may be flush with the edge 9 of the tongue, as shown in Fig. 1, or it may extend above the tongue 9, as shown in Fig. 5, or it may lie at the lower point as indicated in Fig. 6. The lower end of the back blade 3 is beveled at 10 and 11, which two edges are at right angles to each other and each edge 10 and 11 is respectively at an angle of 45 degrees to its adjacent edge 7 or 8, while the lower end of the main blade 1 is beveled at 12 on an angle at 45 degrees to the inner edge 18 of the main blade. The tongue 2 has a short bevel 14 which is at 45 degrees to the inner edge 15 of the tongue, the edges 12 and 14 being in direct line with each other as indicated by dot and dash line designated 16 in Fig. 2.
The tongue 2 is provided with a series of inclined openings 17, the upper edge of each of which is provided with deep notches 18 and the shallower notches 19 which respectively coincide with graduations 20 and 21 on the tongue 2, which graduations represent inches each inch being spaced separately, and the notches 18 and 19 being alternately deep and shallow make it easy to distinguish between the graduation and V edge of'the material by laying a straight edge,
not shown, againstithe beveled edges 12 and 1 permit the ready insertion of the point of a pencil or other marking device therein to hold the same at-the" desired distance from the edge of the material Whichis to be marked. The back blade 3 of the square having been rested against the edge of the material, the square may then be moved along on the material so that a markwill be drawn parallel with the edge of the mate rial. Thisoperat'ion may be performed at either edge of the material by resting either face of the main blade and tongue upon the material, as in either case the hack blade 3 phjhhlhlhhhtheet e in such a manner as to rest against the edge of the material. With the toolthus rested V uponthe material, a line may bedrawn at right angles to the material along the edge 9 of the tongue, or along theedge 15 of the tongue, or at'an angle of 4-5 degrees to the 14, anda line then drawn as indicated by dot and dash line 16 in F ig. 2. VVhenthetool is in thisj position it" isv self-supporting, as the inain blade 1 forms aledge, which rests upomthe upper 'face of the materialand prevents theback blade 3 from falling down. It isto benoted that with the tool in this be. irregular in'cross section, as in the case (if-molding, it only. being essential that the I Width ofthe back blade 3 be wide enough to have a line of contact with that portion 'of1the edge which is to be used as one side of the angle being measured.
In laying out, frames the square may be laid against the material with the back blade 3against the edge ofthe material and 'the tongue and main blade against the face of the material, and with the edge 9 at the desired point, a line may be drawn on the face ofthematerial and then without chang ing the position of the square other than by sliding it down the required distance, a line may-be marked on the edge of the material V by using the edge 6 of the back blade 3. In
this partioularkind of Work the modified Copies of this patent may be obtainedfor form of construction indicatedin Figs. 5
and 6 may be employed with advantage.
Ifdesired, the tool may be laid with the back surface of the back blade 3 in contact graduations 22 an the inner edge thereof? which represent inehee lnehhljl'hl h'hlh tilt till! i, hlhi little the try allele to he Heel "I l l in laying out work obviating the use at a rule or steel square.
The inner edges 8 and 13 of the tongue and main blade may be used as a try square for external angles of the material, while the back face of the main blade 3 and edge 9 of the tongue may be used for trying inside angles. Other uses of the tool will present themselves to those skilled in the art.
What I claim is:
A try square comprising a main blade, a tongue in the same plane with the main bladeand projected-at right-angles to said main blade from one end thereof, the tongue being provided with a series of inclined openings, an edge of each opening having a series of deep and shallow notches for the reception of a marking instrument, a back blade secured directly to and extending along the back edge of the main blade beyond both sides thereof, and the plane of theback blade being at right angles to the plane ofthe main blade and tongue, the end of the back blade being beveled at each side of the main blade, the end-of the main blade adjacent the beveled end of the back blade being beveled and .the nearest corner of. the tongue being beveled in line with the .bevelof the main blade, said blades being thin and fiat with the faces of the main blade and tongue and the back face of the back blade unobstructed.
In testimony whereof, I have hereunto set my hand at Los Angeles, California this 14th day of March, 1914.
