Gas preparation and lighting.

The self-igniting device forming the subject of the present invention and extinguishing of street lights and other gas lamps are characterized by that curved discs turned by a clockwork at a certain time prevent the entry and shut-off of the gas after the Brenner convey that at a certain time they have a weight or a weight Spring allow the valve plug (or valve) to be adjusted so that when gas is admitted to the Burner can be done by an auxiliary burner ignition. The curved disks can by means of a weight lever and a switch hook, which is attached to the gas tap or other Shut-off elements protruding pins or approaches to regulate the gas admission. The same can can also be set so that the lighting respectively. Extinguishing the gas lamps at different predetermined times takes place.

Fig. 1 of the accompanying drawings shows the front view of the device, Fig. 2 the Grundrifs, Fig. 3 the side view; 4 and 5 show the application of the device an ordinary street lamp in view and section; Figures 6, 7 and 8 illustrate various ones Sections of a variant of the device suitable for street lamps.

With the housing a, which contains the clockwork , the plate b is connected by means of the connecting pieces c, Fig. 3, through which the axis d of the hour wheel passes, which is mounted in a bearing piece e attached to the plate b.

The gas supply pipe f is provided with the usual burner g and the auxiliary burner h for maintaining a pilot flame. A cock i with a cock cone / on which a disc k provided with pins / is attached is used to regulate the gas line. The weight lever m is used to adjust the cock cone j , which is rotatably connected to the plate b at m ^l and carries the switch hook η acting on the pins /.

On the axis d sits the dial 0, which is divided into 24 parts according to the hours of the day, and on the axis d there are curved disks ρ p ¹ , which independently of one another according to the time at which the lighting was respectively. Extinguishing of the gas is to take place, can be set, and for this purpose a screw q that is screwed into the dial 0 leads by archers of these curved disks.

According to Fig. Ι is the time to ignite the gas at 6 o'clock in the afternoon and that to extinguish it set at 4:15 a.m. in the morning.

Now, if the axis d extending in the direction of the arrow Fig. 1 rotates, the curve disc acts ρ a pin r at the outward end of the lower arm r ¹ of the lever m. After hereby lever is lifted in and the switch hook η a pin has comprehended, As soon as the highest part of the cam has acted on the pin r , the lever m falls due to the weight attached to it, and the switch hook η adjusts the cock cone of the cock i in such a way that gas flows to the burner g and through the ignition flame of the burner h is ignited.

Claims (1)

As the axis d continues its movement, the other cam plate p ^l gradually rises and, by means of lever m, brings the switch hook η on another pin / to attack. After a certain time, following the movement of the cam, the lever m falls, so that the main flame of the burner g is extinguished and only the pilot flame is kept burning. With every downward movement of the lever m , the cock cone of the cock i always makes a quarter turn in the same direction. The loaded arm s, which is connected to the switch hook η , holds it on the pins /, and the locking spring t, Fig. 1, prevents the cock cone j from being rotated backwards. In order to prevent the cock cone j of the cock i from turning too far when the lever m falls, the head of the switch hook η is designed in such a way that, when it has turned the cock cone j by attacking a pin /, the next following pin is on strikes the head of the hook and prevents further rotation, Fig. i. 4 and 5 show the device with a penalty lantern in the horizontal direction working parts. Instead of loading the lever m as before, a spring u is connected to it, and the weight acting on the switch box η is replaced by the spring ν . The device is enclosed in a housing, the cover of which can be removed in order to be able to adjust the cam disks. In the variant for street lamps shown in FIGS. 6, 7 and 8, the overall arrangement is essentially the same as in FIGS. 4 and 5, but the cam disks and the drive mechanism are arranged in a vertical position. The cam disks ρ p ^l sit on the hub p ^{2 of} the hour wheel and are held on this by the nut p ^{3 so that they} can be adjusted. The screw p * screwed into the end of axis d holds the hour wheel 0 in place on the axis. The housing w is provided with a detachable part w ¹ , Figs. 7 and 8, which is secured on one side by the hook n> ² , Fig. 8, which engages behind the nose w , which is arranged on the fixed part of the housing, and on the other Side is held by the spring hook w ^%, which grips behind the nose W ^ which is seated on the detachable part w ^{1 '.} The clockwork is wound by means of a key inserted through the opening jp ⁶ , Fig. 7, and this opening can be closed by a lid with a button. In cloudy weather it can happen that the penalty lights have to be lit or extinguished independently of the automatic device. For this purpose, around the cock i, through which the gas flows after the burner g , a secondary pipe χ with a cock j, the cock cone of which can be opened and closed by the lever \ in the usual way of the lighter, Fig. 4, 5, 6 and 7. To regulate the gas supply to the pilot flame, a screw ^ ^{1 is} expediently screwed into the gas pipe. The adjustable cam disks can also be set up in such a way that they trigger the cock cone j , which can then be adjusted by a weight or a spring. Patenτ claim: A device for automatic lighting and extinguishing of gas lamps BEZW. for opening and closing the gas inlet to the burner (g) at certain times, characterized in that two cam disks fp p ¹ ) rotated by a clockwork act on a lever fm) in such a way that the valves with the cock cone (j) resp. Valve connected disc (k) is rotated by means of a switch hook (n ) seated on the lever (m) , whereby the device can be made so that when the cock is opened, respectively. Valve the gas is automatically ignited. For this purpose 2 sheets of drawings.
