MULTIANGULAR MITER ATTACHMENT Filed Jue 14, 1948 MPe y Zes www5 .Patented May 29, 1951 UNITED STATES PATENT OFFICE 7 1 Claim.

This invention relates to hand saws.

An object of this invention is to provide a combined saw and miter means so that a carpenter may mark and cut the wood witha single tool on a full set of angles normally used by a carpenter.

Another object is to provide a hand saw with a multi-angular marking or angle gauge and square on the opposite sides of the saw blade adjacent the handle for marking and cutting material at different angles, and a rule or linear scale along the top or back edge of the blade, all calibrated to indicate said angles and linear measure for right or left handed use.

A further object of this invention is to provide a combined saw, square and miter which is useable by a right or left handed person, and which will permit the marking of oppositely extending angles by merely flipping the saw over, rather than turning the board over.

To the foregoing objects, and others which may hereinafter more fully appear, the invention consists of the novel construction, combination and arrangement of parts, as will be more specifically referred to and illustrated in the accompanying drawings, but it is to be understood that changes, variations, and modifications may be resorted to which fall within the scope of the invention as claimed.

In the drawing, Y

Figure 1 is a fragmentary elevation of a hand saw having a miter means secured thereto embodying this invention; t

Figure 2 is a sectional view taken on the line 2 2 of Figure 1;

Figure 3 is a sectional view taken on the line 3-3 of Figure 1.

Referring to the drawing, the numeral I desgnates generally an elongated saw blade formed of a body II having saw teeth I3 along one lengthwise edge thereof and formed with a straight back edge I2. The body Il has secured thereto a handle I4 having a forward body I5 provided with a slot ISIa within which the rear end of the blade I9 is adapted to be secured. The handle I4 is secured to the blade I9 by means of bolts I6 having countersunk heads I'I and countersunk nuts I8. The blade I0 has fastened to the opposite sides thereof a pair of miter or gauge plates generally designated as I9. These plates i9 are formed with a straight rear edge 20 disposed at right angles to the back edge I2 of the blade I@ and each plate I9 is formed with a right angular rib 2| which provides a right angular shoulder 22 disposed at right angles to the back edge I2. The plate I9 is also formed with an angled shoulder 23 which in the present instance is disposed on an angle of substantially 20 and extends from the upper or back edge of the plate I9 on a downward and rearward inclination. The plate I9 is also formed with a second shoulder 24 disposed forwardly of the shoulder 23 and in the present instance the shoulder 24 is disposed at an angle of substantially 32 being inclined downwardly and rearwardly from the back edge I2. The plate I9 at its forward edge is formed on an angle of substantially 45 as indicated at 25 with the angle 25 extending downwardly and rearwardly from the back edge I2. The two plates I9 are of like construction and are secured to the opposite faces of the blade I0 by means of rivets or fastening members 26 which are countersunk as indicated at 21 at their opposite ends in the plates I 9. The upper edges of each plate I9 are formed with graduations 28 which are continuations of graduations 29 formed on the upper or back edge of the blade l0.

In the use of this saw, the saw may be used in the conventional manner for cutting through wood and when it is desired to out the wood on an angle the saw is laid on the wood with one of the shoulders of plate I9 abutting against an edge or end of the board. The board is then marked along the back edge I2 of the saw blade and the board may then be cut along the marked and angled line. With a saw as hereinbefore described, the carpenter will be able to quickly and accurately mark angled lines on the board at either or both ends and it is only necessary to turn the saw over to form oppositely angled lines at each end of the board thereby eliminating the previous practice of turning the board over to form the oppositely angled lines. This saw will provide as a single element a tool which will eliminate the use of both the saw and miter forming means and by providing the mitering means on the rear portion of the saw blade with the mitering means angled downwardly and rearwardly the mitering means will not interfere with the normal use of the saw. Furthermore, this saw will effect a substantial saving in cost of tools for a carpenter in addition to effecting a substantial saving in time in the marking and cutting of angled lines.

What is claimed is:

In a tool having an elongated blade having a front end and a rear end and formed with one straight edge, a pair of triangular stepped gauge plates disposed adjacent the rear end of said 2,554,749 3 4 blade with one right angular edge of each plate REFERENCES CITED parallel with said straight edge and another edge Th f of each plate disposed at right angles to said me of; tllilsvnferens are of record m the straight edge, the hypotenuse of each plate eX- tending downwardly and rearwardly from' said 5 UNITED STATES PATENTS straight edge, the steps of each plate being ar- Number Name Date ranged at varying angles relative to said straight 1,136,790 Funk Apr. 20, 1915 edge with the lowest step foremost, means rig- 1,455,564 Biddle May 15, 1923 idly and permanently securing said plates to said 1,754,035 Morren Apr. 8, 1930 blade, a vhandle projecting from said rear one of l0A said blade -and abutting against said right angularly disposed edges of said plates, and means removably securing said handle to said blade.
