Abstract: A distance measuring device is provided consisting of a frame, a wheel mounted to the frame for rotation about an axis and having a peripheral surface to be rolled against a surface to be measured, a distance counter, a lever arm mounted to the counter for pivoting movement between a first position and a second position, a structure on the counter for indicating a predetermined increment of distance as an incident of the lower arm moving from its first position to its second position, structure for normally biasing the lever arm into its first position, structure on the wheel for engaging the lever arm and moving the lever arm from its first position to its second position as an incident of the wheel rotating about its pivot axis in a first direction, and structure on the lever arm for both (1) intercepting the arm-engaging structure on the wheel and (2) deflecting as the arm-engaging structure moves against the intercepting structure with the wheel rotating oppositely to the first direction to thereby allow

Abstract: A tape measure having sidewalls spaced apart a distance slightly greater than the width of the tape to define a small clearance at opposite edges of the tape with the sidewalls. The sidewalls define midway therebetween a center plane. A peripheral portion of the sidewalls adjacent the peripheral wall of the housing defines guide means adjacent the tape-passing opening for causing the centerline of the tape, as it is passed through the opening, to be accurately at the center plane, thereby effectively minimizing edge wear of the tape in the use of the tape measure.

Abstract: A wheeled measuring device having selectively usable and positionable hub elements for use with a plurality of different measuring wheels and corresponding gearing for utilization of a counter to provide different readouts in effecting desired measurements. The hub elements are received in a recess in the housing of the measuring device and retained therein as a result of securing together of separate portions of the housing of the measuring device in the manufacture thereof.

Abstract: A method of and apparatus for measuring distance selectively along any one or more of an outwardly facing subjacent surface, such as a floor surface, a horizontally facing surface, such as a wall surface, and a downwardly facing surface, such as a sealing surface. The measurement is effected by utilizing an extensible mounting member carrying, at one end, a measurement wheel and an associated counter/indicator adapted to be viewed by a person utilizing the device and grasping the opposite end of the mounting member in effecting a rolling movement of the wheel along the surface to be measured. Locking structure is provided for selectively locking sections of the extensible mounting member in an infinite number of different extended dispositions. The mounting member permits the user to effect the different measurements with a single adjusted arrangement of the mounting member or a plurality of different adjusting arrangements as desired.

Abstract: A wheel is provided for a measuring device of the type having a frame, a distance counter having an actuating lever thereon and mounted on the frame, and structure for mounting the wheel on the frame for rotation about an axis. The wheel has an annular surface for engaging and rolling against a surface along which a distance is to be measured, first and second annular side walls spaced axially with respect to the wheel axis and connected to the annular rolling surface with each side wall having a thickness in an axial direction, a hit pin, and structure for securing the hit pin to the wheel so that a part of the hit pin projects axially from one of the side walls to engage and operate the actuating lever on the counter as an incident of the wheel rotating relative to the frame.

Abstract: An actuator for use with an aerosol container including a depressor bar having opposite hooks at the ends thereof embracing oppositely projecting annular walls of the container. The upper hook includes a retainer at the distal end of a spring finger portion thereof configured to retain the depressor bar in spaced relationship to the container while permitting inward urging of the depressor bar to urge the distal end of the retainer against the spray nozzle for actuation thereof.
