Abstract: 451,504. Scoring devices for games. PRIEST, H. C., 46, Harrow Road, Rockdale, near Sydney, Australia. Feb. 4, 1935, No. 3548. Convention date, April 4, 1934. [Class 132 (ii)] [See also Group XIX] In a scoring device for bridge and like card games, the trick and premium scores are registered and indicated by two discs or sets of discs on spaced vertical axes, the trick score being automatically added to the premium score by ratchet mechanism on a third vertical axis. The invention is described as applied to a device for scoring Auction Bridge. The mechanism is contained in a casing 30 having a lid 31 the surface of which is divided by vertical and horizontal lines 32 in the usual manner. The mechanism on the left of the vertical line for keeping the score of one partnership is identical to and separate and distinct from that on the right of the line for keeping the score of their opponents. Trick points for each side are scored below the line 32 by the clockwise rotation of a units disc 46 and tens ring 47 by means of a stylus inserted through slots 41 in the casing, and are indicated by numerals on the disc and ring viewed through apertures 42 in the casing. Honours and other premiums are scored above the line 32 by a units disc 54 and tens and hundreds rings 55, 56 rotated by a stylus through slots 39 and viewable through apertures 40. Transfer mechanism is provided between the denominations of both sets of indicating elements. In addition, means is provided to accumulate the trick points on the premium scorer which thus serves to indicate the total score. For this purpose the units discs 46, 54 are connected through a free wheel device comprising a pinion 61 meshing with teeth on the disc 46 and formed rigid with a ratchet wheel 67 co-operating with a pawl 66 on a gear 62 meshing with teeth on the disc 54.

Abstract: 854,810. Valves; hydrants. BOPP & REUTHER G.m.b.H. Feb. 5, 1958 [Nov. 20, 1957], No. 3769/58. Classes 69 (1) and 135. A valve in a water hydrant comprises an upper screw-actuated element 1 fitted with a resilient washer 6 to form a piston-like seal which when the valve is closed sealingly engages the interior of a valve sleeve 7 and on opening of the valve moves out of the sleeve and into frictional engagement with the sides of a recess 3 in a lower valve element 2 to move with and unseat this lower element. The element 2 slides along guide ribs 5 and is formed with channels 16 to allow escape of liquid from the recess 3. On closing the valve the frictional connection between the element 2 and the washer 6 is assisted by the buoyancy of the element 2 which is made of light weight plastic. Both elements move upwardly together until the lower is arrested by its seating. To ensure a more positive seal between the washer 6 and sleeve 7, a tube 12 may be fitted so that when the valve is closed the washer 6 is squeezed between the element 1 and a metal washer 11.
