A plurality of marking templates are attached to the spaced measuring tapes, at specified intervals. These marking templates can impart a line pattern to a surface above which they are placed by deployment out of the reel case. The line patterns are usable to position construction elements such as wall studs. The measuring tapes and their attached marking templates can be wound back into the reel case of the reel housing after use. | 02-26-2009 |
20090133275 | Chalk Line Marking System - A chalk line is marked by attaching two hooks to a nail, and then extending a string a length from the nail. The hooks are attached to an apparatus that has multiple springs, such that there is a string attached to the rear of the apparatus while the hooks are attached to the front of the apparatus. When the string has been extended the desired length, the user then snaps the line to make a chalk line. Then, the pull on the string is released by the user, causing the two hooks to separate. When the two hooks separate, their connection to the nail is broken. The hooks and the apparatus associated with the hooks then is free to be reeled back to the user. The user does not have to return to the nail to remove the hooks and the associated apparatus. | 05-28-2009 |
