There is disclosed an internal sizing apparatus comprising a pneumatically activated probe that moves axially within a shoe and non-destructively measures the interior dimensions of the shoe. A linear pneumatic actuator is mounted between a heel piece and a probe. A linear potentiometer is mounted above the actuator and also connects to the probe. The apparatus is inserted into a shoe with the heel piece seated against the interior heel portion of the shoe. A computer system controlling the actuator extends the probe linearly into the shoe until the probe contacts the toe portion of the shoe. The potentiometer then measures the linear distance traveled by the probe and thus determines the internal linear dimension of the shoe. Depending on the type of probe, three-dimensional internal measurements of the shoe can also be quantified.

For a better understanding of the invention, its operating advantage is in the specific objects attained by its uses, reference should be had to the accompanying drawings and descriptive matter in which there is illustrated at least one preferred embodiment of the invention.

An improvement on the structure of a measuring tape device is that a magnetic mechanism is secured at the distal end of a measuring tape. The magnetic mechanism is not placed onto the leg piece of the hook member and thus is not formed as part of the body of the hook member of the measuring tape. The front end of the magnetic mechanism is placed in alignment with the “0” cm mark on the measuring tape. During measuring process of an object of measurement and a designated point, the magnetic mechanism allows the measuring tape to be magnetically attached to the surface of the object and anchored at the exact starting point of measurement, and therefore, the measuring precision will not be skewed because of thickness of the hook member or because of the gap caused by the movable mechanics of the hook member.

An apparatus can be conveniently and temporarily attached to a tape measure to aid in measuring a workpiece. The apparatus has a means of engaging a workpiece at one end of a length to be measured, and has a means of removably attaching to the tape measure. The attachment mechanism consists of a rigid, substantially flat member which is designed to rest under the tape, with two tabs protruding upwards from said rigid member. Each tab has at least one kerf formed in the side of that tab which is adjacent to the tape when the rigid member rests under the tape, so that the curving edges of the tape fit into those kerfs, holding the apparatus in place. In this manner, the apparatus is conveniently attachable to and removable from the tape. Furthermore, while the apparatus is attached to the tape, the apparatus adds stability to the tape, by reinforcing the position of the curving edges of the tape. Also, the apparatus can be conveniently slid along the tape to whatever position is appropriate for engaging a workpiece to be measured. The engagement mechanism of the apparatus consists of a rigid, substantially flat member which is attached to the attachment mechanism at a substantially ninety degree angle, so that the rigid engagement member is substantially perpendicular to the tape. One surface of the engagement member is designed to rest against and engage a workpiece to be measured, in a manner which does not harm or mar the workpiece. The surface engaging the workpiece can be tacky, or can have a protrusion designed to insert into a hollow workpiece, such as a pipe.

A multi-purpose measuring tool has an elongate base and arm pivotally connected at rounded ends thereof in an angularly variable relation to perform multiple functions, including measuring inclines, measuring corner angles, measuring distances, use as a square, use as a bevel gauge and use as a torpedo level. A retractable measuring tape housed within the arm has a terminal finger gripping end adapted to be pulled away from the arm and removably attached to a distal end of the base. The measuring tape is dual purpose in that one side of the tape is used for determining the angle of the arm relative to the base to perform some of the above functions, and the other side of the tape is used for traditional linear distance measurements. The tool's base includes a "vertical" bubble level and the arm includes a "horizontal" bubble level to perform some of the above functions.

A measuring device includes a square ruler body provided with a plurality of scales, a plurality of marking lines, and a plurality of counting numbers. Each of the counting numbers has a corresponding numeral which is located under the respective the counting number for measurement of different directions. Thus, the measuring device is used to measure the size of the workpiece at any direction and any start point, thereby greatly saving the measuring time and the manual work. In addition, the counting numbers have a two-dimensional corresponding manner so that the measuring device can obtain the size of the workpiece instantaneously from left to right or from right to left without having to rotate or change the direction of the ruler body.
