4 Claims.

This invention relates to cutting machines for sheet material, and more particularly to a cutting machine for imitation brick siding sheets.

A main object of the invention is to provide a novel and improved cutting machine for brick Siding sheet material or the like, of very simple construction which is inexpensive to build and very easy to operate.

A further object of the invention is to provide an improved cutting machine for sheet material of the type employed for imitation brick siding and the like, wherein the exterior surface of the sheet material is substantially rigid or semirigid and the bottom surface of the material is more or less porous, fibrous Or deformable in nature, such as a bottom surface of Celotex or the like, the machine being adapted to provide a flat steady support for the material being cut and being provided with means for accurately perforating the rigid exterior surface of the sheet along a desired line of cut.

Further objects and advantages of the invention will become apparent from the following description and claims, and from the accompanying drawings, wherein:

Figure 1 is a plan view, partly in cross-section, of a cutting machine constructed in accordance with the present invention.

Figure 2 is a detail cross-sectional View taken on line 2-2 of Figure 1.

Figure 3 is a side elevational View, partly in cross-section, of the cutting machine of Figure 1.

Figure 4 is a detail cross-sectional view taken on line 44 of Figure 3.

Figure 5 is a detail view of the cutting wheel and its support as employed in the cutting machine of Figure 1.

Referring to the drawings, II designates a table of suitable size and generally rectangular in shape adapted to receive and support a slab of imitation brick siding or similar sheet material during the cutting thereof. Secured to table II adjacent one corner thereof is a bracket member I2 formed with a pair of spaced parallel lugs I3, I 3 receiving a bolt Id. Pivotally mounted on bolt It between lugs I3, I3 is an arm I5 extending toward the opposite side of table I I and inclined with respect thereto at an angle of about 45, although other angles may be employed within the spirit of this invention. Arm I5 is formed with a vertical rib I 6 to increase its rigidity. The end of arm I5 is recessed to form a pair of horizontal, spaced lugs I1, I! and adjustably secured therein is a bifurcated bolt member I8.

Rotatably secured between the depending fingers of member I8 is a cutter wheel I9. I I

Secured below the surface of the table adjacent bracket I2 is a vertical bolt member 2| which projects upwardly through the table surface and through arm I5. Pivotally secured to thetop end of bolt member 2I is a lever member 22 formed with a cam portion 23 adapted to cooperate with the upper horizontal surface of the'main body portion of arm I5. Lever member 22 is further formed with a laterally offset handle portion 24. A coil spring 25 encircles bolt member 2| and bears between a pin 26 extending through the lower portion of said bolt member and the under surface of arm I5, biasing said arm to a raised position. When arm I5 is in its depressed posi-. tion, as shown in Figures 1, 2 and 3, cutter wheel I9 is disposed closely adjacent the surface of table II. When lever 22 is rotated to a substantially vertical position, spring 25 raises arm I5 so that cutter wheel I9 is spaced a substantial distance above table II, providing clearance for the rapid insertion or removal of sheet material.

Rotatably supported below the surface of table II in a transverse vertical plane which includes cutter wheel I9 is a shaft 21 provided at the end thereof adjacent cutter wheel I9 with a pair of

circular saw blades

28, 28 parallel to and spaced a short distance on either side from the plane of cutter wheel Ill. The upper peripheral portions of

saw blades

28, 28 project through slots 29 provided therefor in the surface of table II and said peripheral portions project a slight distance above the plane of the table. The teeth of the saw blades are arranged to engage the bottom fibrous or deformable surface of a sheet of siding material and to move said sheet into cutting engagement with cutter wheel I9 responsive to rotation of shaft 21.

The other end of shaft 21 has mounted thereon a bevel gear 30 which is in mesh with and is adapted to be driven by a bevel pinion gear 3| carried on a shaft 32 journalled in table II and provided with an external crank handle 33. When crank handle 33 is rotated, torque is transmitted through the bevel gears to shaft 21, causing

toothed blades

28, 28 to rotate. If a sheet of siding material is placed on table II with its porous or fibrous side down, the toothed blades will engage said fibrous or porous side and feed the sheet against cutter wheel I9, assuming arm I5 to be in its depressed position. Cutter wheel I9 will indent or shear the rigid or semirigid upper face of the siding material along the desired line of feed and upon removal of the sheet the partly severed portions thereof may be readily separated.

An access door 24 is provided in the side panel of table II

adjacent blades

28, 28 to permit con- .venient removal and replacement of the blades when required.

While a specific embodiment of a cutting machine for imitation brick siding material or the like has been disclosed in the foregoing description, it will be understood that svarious :modifi cations within the spirit of the invention may occur to those skilled in the art. Therefore it is intended that no limitations be placed on the invention other than as defined by theiscopefiof the appended claims.
