ABSTRACT:
An improved portable mechanical roller measure device for moving forwardly along a surface and thereby measuring a distance there along. The device comprises a housing which supports a rotatable wheel or roller. The rotation of the roller is transmitted through a simple symmetrical straight-toothed gear arrangement to a counter mechanism, which indicates the distance over which the device has traveled along the surface being measured. The roller measure device may be used in a hand-held fashion or may be connected to an elongated handle. The handle has an attachment section for detachably connecting to exterior attachment sections at either the rear or front of the housing so the device can either be pushed or pulled in its forward measuring direction. The housing and handle, and their respective attachment sections are preferably low cost molded plastic parts which are designed and configured for quick, easy interconnection and disconnection of the handle, high strength at the point of attachment, and added rigidity in the plane of movement of the device. The handle may be comprised of a plurality of releasably interlocked sections.
