Abstract: The RAZOR TIP is a carpenter's pencil sharpening guide. It is designed to be used with a utility knife. Carpenter's pencils are traditionally flat, and wide in shape, making them difficult to sharpen by hand. The RAZOR TIP solves this problem. At the time of this patent application filing there was only one other similar type product available on the market. However, this pencil sharpener was only good for creating a round point on a carpenter's pencil. This defeats the purpose behind the design of the carpenter's pencil. It is designed to provide the user with a flat, and wide lead point which is less susceptible to damage when used on unfinished, and rough surfaces. The RAZOR TIP maintains the original shape of the lead point.

A ring gage which has a first and second scribe line thereon is used to establish a male timed rotary connection of a first tool. The angular distance between the first and second scribe lines is the advance timing correction (ATC), i.e., the angular distance between hand tight face-up and full torque make-up of a rotary connection comprising the male timed rotary connection of the first tool and a female timed rotary connection of a second tool.

The third scribe line on the pin gage corresponds to the first scribe line on the ring gage. The third scribe line is transferred onto the second tool. When the first and second tools are rotatively connected at full torque, the transferred lines on the tools are in general angular alignment.

Abstract: Drills (35), vertically oriented in a row/column array in a drill block (31), are moved in the column direction across a slot (49) located at a loading station (41). As the drills in each partially or fully occupied row reach the slot and drop, drill block movement halts. Thereafter a vertically oriented turn-over tube (51) is moved in the row direction beneath the slot (49). When an occupied drill position is reached, the drill drops into the turn-over tube, tube row movement temporarily halts, and the tube is rotated. The drill slides out of the turn-over tube (51) and down the channel (59) of a measuring station (43) until it hits a movable stop (61). After drill diameter is measured by a pneumatically positioned LVDT (87) and overall drill length is measured by a pneumatically positioned linear potentiometer (69)/proximity detector (PX3) combination, the stop (61) is withdrawn and the drill enters a clamp (95), which grips the adapter shank of the drill.
