Abstract: A pointer for an indicating instrument is constructed of material transparent to light, the pointer having an elongated shape and a cross section having two inclined sides directed towards an apex, and a lower side opposite the apex and facing a face of the indicating instrument. The lower surface is provided with a layer of coloring, substantially opaque to the light, and giving a colored appearance to the pointer upon viewing the pointer by looking straight down upon the indicator face or at an angle thereto. The inclination of the pointer sides provides for respective refraction and total internal reflection to viewing rays of light which make visible the coloring.

Abstract: A support (2) which serves for fastening a pointer (1) on a pointer shaft has, towards the top, a holding part (12) which is developed as an expansion rivet. The pointer (1) has a central passage (13) through which the holding part (12) engages. A cap (3) is provided with an expansion pin (14) which is adapted to be pushed from above into the holding part (12) when the cap (3) is mounted. In this way, the expansion rivet is expanded and the pointer (1) is thereby attached firmly to the support (2). A projection (16) on the holding part (12) which engages into a recess (17) in the pointer (1) determines the exact angular position of the pointer (1) with respect to the holding part (12).

Abstract: An improved pointer and shaft adapter assembly for use in instruments such as the speedometer of a vehicle including an elongated pointer portion and shaft forming portion connected together by engagement between spaced tabs which project from the pointer lying alongside side wall surfaces of an end connector of the shaft adapter. Cooperative nibs and apertures of the pointer and shaft forming portions secure the parts together and prevent any substantial tilting movement therebetween.

Abstract: An improved liquid filled gauge for measuring the temperature or pressure of a fluid. Gauge temperature or pressure readings are indicated by a pointer configured to produce substantial resistance to motion during pointer rotation. The preferred embodiment employs an elongated flat sheet pointer having three 90.degree. twists; two in the indication end of the pointer to bound a first resistive surface, and a third in the tail of the pointer to bound a second resistive surface.

Abstract: In a pointer sliding mechanism intended for use in a pushbutton tuner, there is fixed on the base plate of the tuner a pair of pivots, right and left, on which right and left links are pivotably mounted at the front ends thereof; a pointer mount-plate is pivotably mounted to the right and left links at the rear ends thereof so as to couple these links together. On the other hand, there is provided on the base plate of the pushbutton tuner a memory slide which is movable in the direction of the width of the tuner, and a V-shaped link is mounted between the memory slide and one of the links supporting the pointer mount-plate, which V-shaped link is freely openable and closable; the arm of this V-shaped link on the side of the memory slide is pivotably mounted at the central portion thereof to a pivot fixed to the base plate.

Abstract: A register pointer for an electric utility meter is described as having a weakened section at which fracture can occur to break away the pointer when an attempt is made to tamper with the pointer, such as by manually resetting the pointer's position on the register to show a lower reading of energy consumption. Various forms of breakaway means are described which will permit separation of the pointer portion of the device from its shaft portion when a torque is applied to the pointer end.
