1 Claim. 1
This invention relates to wood-working tools and, more particularly, to tools adapted for cuttin grooves in boards and to slice thin boards and shingles. The tool in question is also used to cut straight strips, squares, triangles or circles out of shingles or boards.
One object of this invention is to provide a manually operated wood-working tool which is equipped with a replaceable cutting knife, a guiding bar under said tool and a pair of holding handles.
Another object of this invention is to provide a manually operated wood-working tool which is equipped with a cuttin knife, a guiding edge under said tool, a handle for operating said tool and a slot running lengthwise of said tool, and an adjustable centering bar to facilitate the cutting of small circles in shingles, boards, etc.
Still another object of this invention is to provide a wood-working tool which is equipped in the front portion thereof with a replaceable cutting knife and an opening to permit the insertion of an extra long centering rod to facilitate the cutting of extra large circles in shingles, boards, etc.
Other objects will be seen as the description of this invention will proceed.
Referring briefly to the drawing:
Fig. 1 is a perspective view of the wood-working tool showing the cutting knife, the knob and handle for operating said tool and the elongated slot facilitating the adjustment of the centering rod.
Fig. 2 is a side view of the wood-working tool showin its front portion in partial cross-section.
Fig. 3 is a top elevation of the tool shown in Fig. 2.
Fig. 4 is a front elevation of the tool shown in Fig. 2.
Fig. 5 is a section on the line 5-5 of Fig. 2.
Fig. 6 is a section taken on the line 6-6 of Fig. 2 showing the position of the centering rod when cutting small circles in shingles or boards.
Fig. 7 is a plan view of the tool applied to a fragment of a shingle or board, illustrating the manner in which the tool is used to cut a straight out in a shingle or board.
Fig. 8 is a cross-section taken on the line 8-8 of Fig. 2 showing the manner in which the guiding edge fits within the cut of a shingle or board.
Fig. 9 is a view similar to Fig. 7, illustrating the manner in which the tool is used to cut small circles in shingles or boards.
Fig. 10 shows the manner in which the tool shown in Figs. 1 to 9 inclusive is used to out large circles in shingles or boards.
Fig. 11 is a perspective view of the cutting knife used in connection with the tool shown in Figs. 1 to 10 inclusive.
Referring more particularly to Fig. 1, numeral l0 indicates the body of the woodworking tool. The latter consists of an elongated base H having an elongated slot l2 which is located within the sunk-in portion l3 of the tool Ill. The front portion F of the tool [0 has a vertical square aperture l4 made to receive a square tool bit I5 which terminates in a sharp cutting knife l6. The bit I5 is held to the tool 10 and within the square aperture M by means of the set screw ll. A left hand holding knob I8 is secured upon the front portion F, and a right hand holding handle 19 is secured to the rear portion R of the tool Ill. The handle [9 is secured to the tool Ill by means of the fastening screws 20.
A centering tool or bar 2| consisting of an angle-shaped member 22 is secured to the side of the tool 10 by means of an adjustable wingnut 23. The horizontal portion of the angle 22 has a hole 24 which receives a nail N when it is required to cut a small circle in a shingle or a thin board. The nail N in this case serves as a center point around which the circle is described when cutting a round opening.
The tool 10 is equipped with a wedge-shaped guiding edge G, located under the tool and which is used as a guide in cutting operations.
The front portion F of the tool 10 has a hole 25 to receive a long centering tool or rod 26, when it is necessary to out large circles in shingles or boards. The centerin rod 26 consists of an elongated bar 2! which has at one end thereof a centering hole 28 and at the other end a threaded portion 29 having a wing-nut 30. The threaded portion 29 is inserted into the opening 25 and is made fast by means of the wing-nut 30, while a nail N is driven into the hole 28 in the other end of the rod 26. The nail N serves as a center around which a circle is described when cutting large round openings in shingles or boards.
Having described my invention, what I claim is:
A cutting tool comprising an elongated body having a handle at the front end thereof and a handle at the rear end thereof, said handles extending upward from the body, said body havin a sharp-ended cutter bit projecting from the underside of said body forward of said front handle, an arm extending at right angles from said body and having means for securing the 3 same to the body, the free end of said arm having hole therethrough, said tool being adapted to cut a circle in a fiat article by driving a nail through said hole at the center of the desired circle with said cutter bit positioned in the cir- 5 cumference of the desired circle and then depressing the front end of the tool and swinging the same about said nail as a center, said means comprising an arm extending upward at right angles to said first arm, said body having a 1ongitudinal horizontal slot therethrough, a screw bolt passing through said slot, said upright arm having an opening therethrough, said bolt passing through said opening, and a nut on said bolt releasably clamping said upright arm against 15 said side of the body.
