| 181 | Timing mechanism | US7590 | 1987-01-28 | US4701056A | 1987-10-20 | Gordon A. Barlow |
| A timing mechanism for use with a board game to indicate by sound and movement the time period allotted for answering a question or performing a turn or function. It includes a sphere such as a marble which rolls on a circular saucer having an upwardly facing conical plastic surface with a central depression. The central depression is sized to receive and hold the marble. An inclined ramp is formed at the periphery of the circular saucer and it has a width and incline sufficient to permit the marble to roll from the ramp onto the upwardly facing concave surface. A starting pad is located at the top of the inclined ramp on which to place the sphere to begin its downwardly roll. The starting pad is inclined so that the sphere and marble will not rest on the starting pad, but will immediately start its downwardly inclination when released. The circular saucer is formed of a thin-walled plastic which produces sound when the marble rolls down the ramp, circles the upwardly facing conical surface and ultimately comes to rest in the central semi-spherical depression. | ||||||
| 182 | Quickly resettable timer | US747857 | 1985-06-24 | US4648721A | 1987-03-10 | Edward Shapiro |
| A quickly resettable timer is claimed which comprises a container having a base end and a reset end; a quantity of a flowing, particulate solid medium; a funnel-like receptacle having a loading orifice nearest the reset end and a metered orifice nearest the base end, the receptacle being mounted to and spaced from the interior wall sections of the container such that the particulate medium in the base end will flow over and around the receptacle and into the reset end upon inversion of the timer by rotation in any direction; and a ring fitted snugly against each interior wall section of the container intermediate the receptacle and the reset end, the ring having an aperture positioned above and sized smaller than the loading orifice of the receptacle. Preferably, the ring has inwardly protruding sides which taper toward each other to define the aperture. Most preferably, the receptacle and at least a portion of the container are made from a substantially transparent material. | ||||||
| 183 | Multiple selectable timer | US366830 | 1982-04-09 | US4408894A | 1983-10-11 | Richard E. Hemperly |
| A multiple selectable timer of the flowing medium type includes a housing including a medium reservoir and a catch chamber with a timing orifice for controlling the flow of the medium from the medium reservoir to the catch chamber and a metering passage for communicating between the catch chamber and the timing reservoir with the passage adapted to selectively meter predetermined portions of the flowing medium to define selected time intervals. The timer is arranged such that selective rotation of the housing in one direction loads the timing reservoir with selected intervals of timing medium and rotation of the housing in the opposite direction selectively removes predetermined portions of the timing medium. | ||||||
| 184 | Hourglass construction | US967298 | 1978-12-07 | US4267588A | 1981-05-12 | Alexander Daniels |
| An hourglass construction comprising a pair of containers arranged with their mouths together and provided with a through passageway for fluent material. | ||||||
| 185 | Timing device | US77561 | 1979-09-21 | US4238846A | 1980-12-09 | Lyndon O. Barton |
| The timing device is one in which two float-type timers, a frame, and an angular base are adapted to measure and control playing time in games such as Scrabble, chess, checkers, and the like. | ||||||
| 186 | Dual timer device | US68460 | 1979-08-21 | US4236242A | 1980-11-25 | Lyndon O. Barton |
| The Dual Timer invented makes use of two fluid-type timers arranged perpendicularly to each other in a simply designed hinged mechanism to measure and control playing time in concentration games such as Scrabble, chess and checkers. The mechanism has no moving mechanical parts and is manually operated. | ||||||
| 187 | Adjustable interval timer | US481140 | 1974-06-20 | US3938315A | 1976-02-17 | Miklos Von Kemenczky |
| Timing apparatus comprising a housing having a fluid-containing conduit and a body movable in the conduit under the influence of gravity includes a valve for controlling circulation of fluid in the conduit and thereby controlling the time elapsed during movement of the body between preselected locations. The housing supports a magnet for sliding movement when the body descends to its lowermost location and a member responsive to such magnet movement initiates audible output indication. | ||||||
| 188 | Device for indicating used parking time | US41954573 | 1973-11-28 | US3874161A | 1975-04-01 | ASLA KRISTOFFER |
| For indicating used parking time a device is provided which comprises a container adapted to be attached behind a car window and sub-divided into two superposed chambers, the upper chamber containing visible flowable material, such as sand. The chambers are interconnected by a throttled passage which is opened for starting non-reversible flow of the material at a rate such that the upper chamber is emptied at the expiry of the parking time.

| A sealed glass cell contains a solution of silver perchlorate in pyridine with other additions as an electrolyte. A hollow platinum cathode attached to an end cap projects through the cell wall at one end and a long silver cathode attached to an end cap projects through the cell wall at the other end. A glass tube surrounds the cathode. A constant current is passed through the cell which dissolves away the cathode. The length of the cathode measured against a scale on the wall of the cell gives a measure of time.

| A gravitational timer consist of elongated body and a weighted object. The elongated body is either a tube or a column. The weighted object is kept in the tube or circle the column, and it is attached to the elongated body. The weighted object is necessarily visible. If a tube, the body is transparent or with a vertical groove. If the body is a column, the object will be totally visible. When the body erect, the object will be effected by gravity and attached to the body with kinetic friction effecting, making the object descends along the body in a constant speed. | ||||||
