DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Turning now to the drawings, the preferred embodiment of the sliding gauge for making measured markings is shown in FIGS. 1-10. The gauge 10 generally comprises an elongated body 20, a telescoping member 30, a threaded fastener 40 securing the telescoping member 30 to the body 20 by a knob 50, a pair of butt legs 60 for sliding against an edge of a work piece, and a plurality of guiding wells 70.

The elongated body or frame 20 as shown through out the Figures is preferably made of rigid plastic and is rectangular in shape having a width of about 2 inches, a length of about 5 inches, and a thickness of about ¼ inch. These dimensions were chosen by Applicant so as to provide an easily used and stored gauge. However, it is contemplated as being within the scope of invention that the device can be made on a larger or smaller scale and still achieve the same results. The elongated body 20 has a centrally located elongated slot type aperture 80 through the body 20 so that the telescoping member 30 can be adjustably tightened against the body 20. The elongated slot 80 is preferably ¼ inch in width and preferably about 4½ inches long.

The butt legs 60 as shown in FIGS. 1, 3, 4, and 6 are preferably ¾ inch in height, 1 inch in width and ⅜ inch in thickness. Each of the butt legs 60 have a flat front face 90 for placement against an edge of a work piece. During use, the butt legs are butted against the edge of a work piece 100 as shown in FIGS. 8 and 9. This allows the measurements made by the gauge 10 to be made with reference to the edge of the work piece 100. The guide wells 70 and measurement marking 110 are made in reference to the front face 90 of the butt legs 60. Therefore, when the butt legs 60 are placed against the edge of a work piece 100 the measurements are being made with reference to the edge of the work piece 100.

The telescoping or moveable member 30 as shown in FIGS. 4-7 is preferably T shaped and made of rigid plastic having a minor width 120 of 1¼ inches, a major width 130 of 2 inches, and a length of 5 inches. An aperture 140, preferably having a diameter of ¼ inch is used to receive the threaded fastener. The back side 150 of the telescoping member 30 has a six sided retaining wall 160 about the aperture 140 designed to retain the head 170 of the fastener 40. The telescoping member 30 has a plurality of reference or measurement markings 110 on the top surface referencing the distance from the front face 90 of the butting legs 60 to the top edge 180 of the telescoping member 30 so that a user of the device 10 can adjust the relationship between the telescoping member 30 and the body 20 to measure a predetermined distance form the edge of a work piece to the top edge 180 where a marking can be placed.

The threaded fastener 40 as shown in FIGS. 4 and 7 is preferably a 1 inch long slotted bolt with ¼×20 threads and a ⅜ inch six sided head. The shaft of the threaded fastener fits through the aperture 140 within the telescoping member 30 and the elongated slot 80 of the body 20 where the knob 50 is fastened onto the end of the fastener 40. The head 170 of the fastener 40 is retained within the retention wall 160 allowing the fastener 40 to remain stationary as the knob 50 is turned about the threads of the fastener 40.

The knob 50 as shown in FIGS. 1-3 is preferably hexagon shaped to provide gripping surfaces 190, measures 1 inch across and is preferably made of a rigid plastic. The knob 50 may be loosened about the threaded fastener 40 to allow repositioning of the telescoping member 30 with relation to the body 20. The slot 80 in the body 20 allows the shaft of the threaded fastener 40 extending through the slot 80 to move within the slot 80 when telescoping member 30 is extended or retracted with relation to the body 20. When a user positions the telescoping member 30 to a desired position, the knob 50 can be tightened about the threaded fastener 40 thereby tightening the top face 190 of the telescoping member 30 to the bottom face 200 of the body 20 fixing the relationship between the telescoping member 30 and the body 20.

The instrument stops or guiding wells 70 as shown in FIGS. 1, 3, 4, and 6-8 are preferably ⅛ inch wide and are spaced {fraction (5/16)} inch on center apart. The guiding wells 70, also referred to as measurement locating teeth, allow a user of the gauge 10 to place the tip 210 of a marking instrument 220 such as a pencil or pen into a well 70 at a measured distance from the front face 90 of the butt legs 60 as shown in FIG. 8. The user of the device 10 may then slide the device 10 along the edge of a work piece with the tip of the marking instrument 220 being guided by the guiding wells 70 making a mark 230 parallel to the edge of the work piece 100 as shown in FIG. 8. In the preferred embodiment shown through out the drawings, the guiding wells 70 are spaced such that placement of the tip 210 of a marking instrument 220 against the proximal wall 240 of a guiding well 70 will place the tip 210 of the marking instrument 220 at ¼ inch increments from the face 90 of the butt legs 60. Placement of the tip 210 of a marking instrument 220 against the distal wall 250 of a guiding well 70 will place the tip 210 of the marking instrument 220 at 118 inch increments from the face 90 of the butt legs 60.

The gauge 10 can be used in a plurality of applications where making measured markings are needed such as in the installation of building siding as shown in FIG. 10. The butting legs 60 can be place against the lip of a course of siding 260 so that the measurements made with the device will be made making reference to the lip of the course. This is helpful in that the user can simultaneously measure and mark where the next course of siding has to be placed in relation to the previous course 260 of siding installed.

FIGS. 8 and 9 show how a marking instrument 220 is used with the gauge 10. FIG. 8 shows how the guiding wells 70 guide the tip 210 of the marking instrument 220 as the gauge 10 is slid along the edge 270 of the work piece 100. FIG. 9 show how the top edge 180 of the telescoping member 30 can be used as a guiding member for distance from the edge 270 of a work piece 100 that extend beyond the length of the body 20.
