Abstract
A multi-blade drywall cutter (MBDC) for making multiple simultaneous cuts to a piece of drywall. The MBDC has a first member pivotally connected to a second member, and first and second handles are attached to aid in use. The first member contains rollers to aid in using the cutting device and also a track that can be adjusted to vary the width to receive a board of various thicknesses. The second member has a plurality of cutting elements that may be located at various positions along the second member and secured for cutting.
Claims
1. (canceled)
2. I claim as being the inventor of a MULTI-BLADE-DRYWALL-CUTTER which is designed to cut mass production of drywall rippers (upon a 48 and or 410 sheet of drywall board. It's designed to reduce labor time in hanging drywall in the commercial home industry. Also, it's light weight and when in its retractable closed position, it makes it very practical to carry to a job site
3. Unique drywall-ripper-number-system (1-6 inch) scale system allow as many as ten razor blade housings to be set within seconds.
4. Retractable (T-configuration) becomes a (linear-configuration) comparative to a 248 STUD being transported to a job site.
5. Removable Handle and Knife-Blade-Insert-Housings makes its simple for storage.
6. Weight of MULTI-BLADE-DRYWALL-CUTTER is less than five pounds.
7. Match cuts or (scorings) are precise to allow the drywall-rippers to have uniform widths. After scoring the front side of a drywall board, simply by turning the drywall board around, the M.B.D.C. machine will make an exact match cuts.
8. Adjustable Gauge can provide various dimensional widths for , & drywall boards. The Horizonal Track that houses the series of spinning rollers, can slide (in & out) to make these adjustments. There are two slots located at the lateral ends of the M.B.D.C. machine which are locked by an Adjustable Screw.

DETAILED DESCRIPTION OF THE SEVERAL VIEWS OF THE PRESENT INVENTION
[0023] FIG. 1 is an illustration of the multi blade drywall cutter (MBDC) (1) which provides a pulling direction (2) of the MBDC (1) across a piece of drywall (3).
[0024] FIG. 2 is a plan view of the MBDC which has a general T-shape configuration (8) and has a first member (4) with a stationary handle (9) attached. The MBDC further has a second member (5) attached to the first member (4). The second member (5) has a plurality of cutting blades (6) spaced along the second member (5). The second member (5) further has a removable handle (7) attached and is configured to aid in pulling the MBDC by a user across a piece of drywall.
[0025] FIG. 3 shows the MBDC in a closed position (10), where the first member (4) is connected to the second member (5) by a pivot pin (11).
[0026] FIG. 4 is another view of the present invention of the MBDC with stationary handle (9) and removable handle (7). The first member (4) has a first track (13) with a retractable feature which will be explained in greater detail below. The first member (4) further has a second track (14). Further, the plurality of cutting blades (6) are spaced along the second member.
[0027] FIGS. 5-7 are more detailed views of the cutting blade (6) of the MBDC. The cutting blade (6) has a razor blade (12) contained within a knife housing (15). The knife housing (15) is further received in an insert housing (13). Further, a locking paddle screw (14) is received in the insert housing (13). FIG. 6 is an exploded view of the cutting blade. In addition to what is shown in FIG. 5, three screws (16) are used for locking the knife housing (15) within the insert housing (13). As shown in FIG. 7, the locking paddle screw (14) is received in a tapped out hole (16) of the insert housing (13).
[0028] FIG. 8a provides an end view of the second member (5) of the MBDC. As shown, the locking paddle screws (14) and (17) are received in guide blocks (18) which are received in a slide track (21) for the insert housing (13) or in the slide track (20) for the removable handle (7). The back side of the slide track is represented by arrow (22). FIG. 8b is an end view of the second member (5) without the guide blocks (18) installed.
[0029] FIGS. 9 and 10 are more detailed views of the first member (4) of the MBDC. A series of rollers (26) as provided in the second track (14) and are held in place by assembly bolts (25). As shown in FIG. 10, the stationary handle (9) is mounted to the first member (4).
[0030] As shown in FIG. 11, paddle screws (17) as used to attach the removable handle (7) to the slide track (20). Guide block (18) is received in the slide track (20).
[0031] FIGS. 12 and 13 are more detailed views of the pivot connection between the first member (4) and second member (5) of the MBDC. The pivot pin (27) connects the first member (4) to the second member (5) and permits pivoting of the first member (4) with respect to the second member (5).
[0032] FIGS. 14a-14c provides a more detailed view of the adjustment gage of the first member. The first track (13) is moveable with respect to the second track (14) via screw (28) and slot (29) to vary the width (30) as needed.
[0033] FIG. 15 provides a gage with markings (32). As shown the gage begins at point (31) and the cutting device (6) is able to move and be locked in place via the paddle screw (14).
