Abstract: A height-measuring device in which there is provided a vertically-mounted ruler element and associated slide-mount in which slides a slide having a lower surface for resting on the head of a person to be measured. The slide has a pair of rearwardly extending flanges that act as runners for sliding in channels formed in the slide-mount. The slide has a bracket extending from the flanges, which bracket has a pair of side surfaces which mounts a hexagonal-head screw, the head of which is nonrotatably mounted in one side surface. A locking nut is mounted at the end of the screw and is rotatable in a first direction to urge the pair of side surfaces, which are made of hard plastic, toward each other, and, therefore, also the flanges, to cause the flanges into clamping relationship with the inner surface walls of the pair of channels. The lower surface of the slide is coplanar with a surface which indicates on the ruler element directly adjacent thereto the correct height measurement.
Abstract: The invention comprises a blood lancet device for puncturing the fleshy part on the inner side of a finger tip, or an ear lobe, in order to draw blood for a hemoglobin test, or other type of blood test and which is completely sanitary to avoid any possibility of contamination of the blood drawn for testing. The device includes a finger grip element to be held by a user, with a surface adapted to be engaged with the fleshy finger tip pad, or ear lobe, and a hinged striker element pivotally mounted on the device and spring actuated to drive a sharp puncturing element secured on the striker, into such pad, with a thumb piece on the striker for drawing it back to a cocked position and having a twist-off or tear away protective element for maintaining the sanitary condition of the puncturing element until it is to be used.
Abstract: The invention relates to a flashlight that is adapted to be hand held and wherein the circuit to the bulb is completed by merely a squeezing action on the outer tubular shell of the container, which pressure causes a series of lengthwise metal fingers on a clip mounting the bulb, to be brought into contact with the metal can housing the battery and thus energize the bulb.
Abstract: This invention relates to a pill box comprised of three parts including a shell bottom, a shell top and a slip ring so interrelated that the slip ring holds the top and bottom parts assembled with the slip ring rotatable relative to the assembled parts. The top and bottom parts are nonrotative relative to each other and are formed to cooperate to form a pill discharge opening normally closed by the slip ring with the ring formed with an opening adapted to be aligned with the discharge opening for discharge of a pill from the assembled box.
Abstract: A key holder is provided consisting of an open-ended housing, a tray slidably disposed within the housing and a resilient wire bail, slidably disposed on the housing and attached to the tray so as to move in unison with the tray as the tray is moved into and out of the housing. The bail is detached from the housing and tray and is threaded through the holes of a number of keys. The bail, with the keys mounted thereon, is then attached to the tray and housing by spreading the legs of the resilient bail and inserting dogs formed at the ends of the legs through slots in the sides of the housing and into sockets in the tray. As the tray is slipped into the housing, the bits of the keys are inserted into the housing as well. When the use of a key is desired, the keys, bail and tray are partially pulled from the housing. The key to be used is then rotated away from the housing and the remaining keys may then be reinserted.
Abstract: This invention relates to an ear syringe having a built-in pressure regulator valve to control the discharge velocity of fluid issuing from the nozzle of the syringe, regardless of the amount of pressure applied on the bulb of the syringe, to prevent pain in the ear of a user, or possible damage to the ear as a result of squeezing the bulb too hard, or applying a sudden excessive pressure to the bulb.
Abstract: This invention relates to a light reflecting magnifier primarily for reading and which consists of a magnifying lense mounted in a frame which spaces the lense in properly focused relation to a reading surface and which is circular and having a circular interior reflective wall that tapers from a maximum diameter adjacent the underside of the lense to a smaller diameter opening at the bottom of the mounting frame.
Abstract: A pill cutter of a relatively simple construction, including an upper and a lower member which are hingedly or otherwise affixed together at one end thereof so that one member may be pivotally rotated with respect to the other. On the inner facing surfaces of the upper and lower members of the pill cutter are disposed a pair of resilient pads which are positioned to engage one another when the upper and lower members are pressed together. One of the resilient members is of a split construction, and a wedge is disposed between the split halves thereof. This wedge preferably is of a height which is less than the thickness of the resilient pad so that the apex of the wedge is disposed below the surface of the resilient pad.
Abstract: A fluid dispenser including a container, or alternatively, one which is adapted to receive a bottle or the like for storing a supply of fluid, a push button valve, and a flexible tube connecting the container to the push button valve. The fluid flows by gravity from the container, through the flexible tubing, to the push button valve. The push button valve is spring-loaded, and has a pair of aligned openings through which the flexible tubing extends. In the inoperative or normal position of the push button valve, the flexible tubing is pinned shut at the point where it extends through the openings, thus cutting off the flow of fluid from the container to the push button valve. To operate the fluid dispenser, the push button valve is simply pressed downwardly to align the pair of openings, which reaction releases the crimping or pinching of the flexible tubing, allowing the fluid to flow through the flexible tubing.
Abstract: A paper dispenser which provides a receptacle for holding a supply of paper or memo sheets and having an overlying retainer hingedly mounted on the receptacle with a depending member pivotally mounted on the retainer adapted to engage a topmost sheet on the supply of sheets and advance one sheet at a time.
