Nails could be made to look like a screw whereas the nail head tapers like the head of a screw so when a gun is used, a nail applied to a deeper depth would spread the preset bushing at the top as it finds it's depth.
Turning to figures 5, 6 and 7, shown therein is a perspective view of the small preset depth spacer and finger guard 40 of the present invention. Shown are previously disclosed items.
Turning to Figure 8, shown therein is a sectional side view of the small preset depth spacer 40 of the present invention in use. Also shown are stud 16, sheetrύck 18, backing paper 52, face paper 24, screw head 34, and the face paper pulled and tucked into void 54 after installation.
Turning to Figures Φ, 10 and 11, shown therein is a perspective view of the small preset depth spacer 36 for nails. Other previously disclosed items are also shown..
Turning to Figures 12, 13 and 14, shown therein is a perspective view of the large preset depth spacer 38 for nails. Other previously disclosed items are also shown. Note that two pieces of sheetrόck 18 are present.
Turing to Figures 15 and 16, shown therein is a perspective view of the large preset depth spacer 42 and finger guard for screws.
Turning to Figure 17, shown therein is a sectional side view of the sήiall preset depth spacer and finger guard for screws 40 in use when installing a ceiling. Installing sheetrock 18 όή a ceiling can be awkward because the installer is often όή a ladder and has to position the sheetrόck and hold it in place while driving the screws 32. A plurality of screws 32 is typically started into the sheetrock 18 and driven home once the sheetrock is in place. This relieves the installer of the cumbersome task of handling the screw 32 while holding the sheetrock 18. The present invention 40 may be employed with the started screws 32 when installing a ceiling. The screw 32 is driven into the sheetrock 18 until the preset spacer 40 contacts the surface of the sheetrock 18. The increased area and flared plug configuration Of the present invention 40 provide improved grabbing ability as opposed to a screw head. Furthermore, the preset spacer 40 assures that the screw 32 isn't overdriven as often happens when using just a screw which results in an inadequate amount of sheetrock 18 bearing the weight Of the board. Also shown are facing paper 24, backing paper 52, ceiling joist 56 and gap 58 between the sheetrock and joist.
Turning to Figure 18, shown therein is a side view of the prior aft in use. Screw 32 installation in the prior aft often entails holding the screw until it starts to pull. The rotation of the screw head can damage the user's fingers 60, especially when they have been driving screws Over an extended period Of time. Lacerations 62 occur to the front of the thumb and index finger while holding the threaded part of the screw.
Turning to Figure 19, shown therein is a side view of the present invention lO in use as a finger guard. The present invention 10 may also be used as a finger 60 guard wherein thέ user holds the preset screw device as the screw 32 rotates freely therein. turning to Figure 20, shown therein is an illustrative side view of the prior ait and the present invention 10 in use with screws 32 that have fnissed the stud. The present invention 10 saves installers time when they rhiss the stud 16 because they don't have to try to back up the screw 32 or pull it out with their fingernails because the screw in the sheetrock 18 does not have enough drawing power to pull the preset depth spacer into the sheetrύck s6 the user just grasps the present invention and pulls out the screw.
Turning to Figure 21, shown therein is a perspective view of the large preset depth spacer for stick nails 64. The present invention 64 fnay also be designed tangentially flat 66 On one side of the head 46 to provide dense spacing when used with stick nail for use in a gun.
Turning to Figure 22, shown therein is an illustrative view Of the large preset depth spacer for stick nails 64 installed in and ready for use with an air gun 69.
