Title: Improvements in game apparatus particularly adapted for practising purposes
IPC: G07F17/38
Filed: 1927-11-21
Abstract: 282,361. Lange, C. H., and Vollert, E. W. Dec. 17, 1926, [Convention date]. Golf-practising appliances.-A device for use particularly in practising golf strokes comprises a platform upon which the player stauds, the platform having associated therewith a positioning member for holding the golf ball in a position to be struck by the club, the platform further including a playing field and a target towards which the ball is driven and means for returning the ball to the playing position, these means including a feeding member for engaging the ball, moving it to a predetermined definite position relatively to the platform and maintaining it in this position until it is propelled therefrom by the player. When adapted for use at fairs &c. the device includes automatically - actuated means for delivering a predetermined number of balls, one after the other, to the player after a coin-controlled or a manuallyoperated device is actuated. The player stands on a platform 10 and endeavours to drive the ball 23 into a hole 14 leading to a return trough 17. The ball in passing down the hole closes an electric contact and an audible or visible signal is given. Balls driven beyond the hole enter a transverse channel 13 and pass down the trough 17 at the lower end of which the balls accumulate. In order to use the device a coin is inserted in a slot 60 and is retained by a spring 62, Fig. 3, so as to close an electric contact 61 thereby starting a motor 47 and causing the rotation of gear wheels 37, 51. A lever 31 descends and lowers a cylinder 20 within a vertical tube 19 so as to allow the foremost ball in the trough 17 to roll on to a plate 21. The weight of the ball on the plate 21 depresses a rod 24 and opens a switch 28 in the motor circuit. The switch 61 is also opened by the liberation of the coin caused by a rocking movement of a lever 63. The rotation of the motor is however maintained by the closure of switches 54, 57 liberated by pins on the gear wheels 37, 51, and the cylinder 20 is raised so as to bring the ball on the plate 21 into the striking position shown, in which position the gear wheel 37 opens the switch 54 and stops the motor. When the ball has been driven from the plate 21, the switch 28 closes under the action of a spring 25 and the motor is restarted to bring a second ball into the striking position. When a third ball has likewise been brought into the striking position the gear wheel 51 completes a revolution and opens the switch 57 thus stopping the motor which can then only be restarted by the insertion of another coin. The platform 10 may have a hinged section 10<1>, Fig. 1, supported on cams 87 which may be manually rotated, or automatically rotated from the ball-feeding mechanism, so as to tilt the section 10<1> in order to clear the field of the ball.

Filed: 1965-07-22
Abstract: 1,110,019. Container closures. A. B. HOLMES. 22 July, 1965, No. 31274/65. Heading B8T. [Also in Divisions F2, F4 and G1] A device functioning as a combined pressurerelief valve, liquid viewer and closure member for an aperture in a wall 302 of a container, includes a transparent or translucent viewing member 110 which extends into the container from above to below the required liquid level. The device may be contained in the removable filler cap of an I.C. engine liquid coolant system and may include means whereby the pressure at which the valve operates may be varied, and a further valve which permits the entry of ambient air to enter the container when the pressure therein falls to an excessively low value. As shown, a flange 310 is secured to the container wall around the aperture which is sealed by a gasket 170. The sealing pressure is applied by a rotational movement of the cap 150 which in known manner (e.g. through cams 316, Fig. 2, and a spring bearing plate 140 on the cap) compresses a spring 128. The spring pressure acts through serrated-edge ring members 132, 134 and a flange 114 to apply a sealing pressure to the gasket 170, and by relative rotation of the rings 132, 134 the effective spring length and hence the operating pressure at which the seal 170 is broken by the internal pressure in the container may be selected. The excess pressure is relieved through a vent 314. The spring pressure may alternatively be varied by arranging that the spring bearing plate (242, Fig. 7) on the cap be adjustable away from the cap (Fig. 7). The flange 114 is formed on a transparent viewing device 110 which enables the liquid level in the container to be seen from above the cap, this being suitably apertured for that purpose. An inwardly-opening spring-actuated valve 191 is provided in the viewing device 110 and opens when the pressure in the container falls below a predetermined value.
