SU2783A1 - Electric filament lamp with several filaments, as an additional patent to patent No. 1073 - Google Patents

Description

The present invention is a modification of a multi-filament incandescent electric lamp proposed in the main patent no. 1073. Their common feature is switching by means of a rod, an axially displaced base, while the latter is screwed into the cartridge.

FIG. 1-7 depict the proposed modification of la.mpy.

FIG. Figure 1 shows a lamp in which the ends of the filaments 7 and 2 are attached to two plates 8 and 8, insulating plates 9 and 9 that are separated from the base 5 and passing into contact plates 70 and / O. The threading of one or the other thread (7 or 2) is made by the chip 77, which touches either the plates 70 or 70, depending on how deep the lamp is screwed into the cartridge.

In the lamp according to FIG. 2, contact

organs are arranged as follows. In the insulating mass 6, the tubes 74 and 141 are terminated, terminating in contact (plates) 73 and 73 (in Fig. 3, the contact organ is shown separately). The tube 14 and the contact plate 73 may not be one whole, but consist of two parts connected in one way or another. The ends of the strands 7 and 2 are passed through the tubes 74 and 74 and soldered to them. FIG. 1 and 2 piston 77, moving up, touches either one contact spring or the other. Thus, either one or another thread is included.

If the KOHTaiKTHbie springs are so close to each other that the piston 7-7 can touch both of them at the same time, then it becomes possible to connect both threads in parallel.

If the design of FIG. 2 apply only one contact point

13-14, t: o it is possible to burn either one of the threads, or both in parallel.

In the lamp according to FIG. 4, either one thread is hot, or both are parallel. The ends of the threads are soldered to the piston 7 / and to the sleeve 7. The inclusion of the second thread occurs when the base enters so much into the cartridge that the sleeve 7 touches the contact / 5 located at the bottom of the cartridge. The piston 11 is separated from the sleeve 7 by an insulating sleeve 16.

Another construction of the plinth is shown in FIG. 5. The construction is depicted in three forms: at the bottom of the section, in the middle - a top view, at the top - a bottom view. Here, the contact bodies have the form of a special form of metal plates 17 and 18. These plates pass through the slots 20 and 21 made in the insulating mass 6. strengthened by bending down the projecting end (see bottom view). The slots 20 and 21 are made so large that the threads 7 and 2 pass through them and are soldered to the plates 77 and 18 from the outside (you can, of course, make for the threads and separate holes). The piston 77 constantly touches the plate 77. When the piston 77 is raised when the lamp is screwed into the cartridge, the plate 18 is also attached to it. At the same time, the plate 77 plays two roles at the same time: the contact member and the spring that pushes the piston 77 downwards. It can be seen from the above that in the construction of FIG. 5 hot t or one thread, or both in parallel. FIG. 6 This structure is modified so that it can burn either one or the other thread (switching). Here three sickle plates 77, 18 and 79 are used. Of these, the latter constantly touches the piston 77 and serves as a spring that pushes it downwards. The ends of the strands 7 and 2 are soldered to the plates 77 and 18. When the piston 77 is in its lowest position, the plate 79 touches the plate 17 and the thread 7 is inserted in the chain. When the piston 77 rises, the plate 79 moves away from the plate 77 and touches plate 18. Thus, the thread 7 is turned off, and the thread 2 is turned on. In the structures of FIG. 5 and 6 is absent - a sleeve 7, having in FIG. 1 and 2, in which the piston 77 runs. The presence or absence of this sleeve is not essential for these structures (except for FIG. 4) and depends only on the properties of the insulating material b.

The construction according to FIG. 7 differs from that shown in FIG. 6, the plate 18 is replaced by a metal ring 23 fixed in the insulating mass 6 to which the end of the thread 2 is attached. When the piston 7 is in its lower position, the plates 77 and 79 touch each other and thus the thread 7 | included in the chain. When the piston 77 moves upward, the plates 77 and 79 move away from each other, and the thread 7 is turned off. When, finally, piston 77 abuts ring 23, thread 2 is turned on.

SUBJECT OF THE PATENT.

1. Variation of the electric lamp described in patent No. 1073, characterized by the use of curved contact plates 70 and 70. Separately mounted on the inner surface of the base and connected to the free ends of the threads 7 and 2, which plates electrically replace the contacts 70 and 70 of the main application (Fig. 1).

2.B described in p. 1 electric lamp using contacts 73 and 75, fitted at the ends with tubes 14 and 14 fixed in an insulating mass of the base tube b, cut along a generator and connected to the free ends of the strands 7 and 2 (Fig. 2 and 3).

3. Variations of an electrical la.mpa characterized in patent No. 1073, characterized in that the thread 7 is connected to the piston 77 insulated by the sleeve 76, and the thread 7 to the sleeve 7 fixed in the insulating mass of the base (Fig. 4).

4. Variation of the electric lamp described in patent No. 1073, characterized by the use of 6 caps fixed in an insulating mass by means of slots 20, 27 and 22 and bent by the lower ends of the contact sickle plates 17, 7S and / 9 brought into contact by the piston 11 when it is moved when screwed lamp (Fig. 5 and 6). 5. In the incandescent lamp described in paragraph 4, use, instead of the plate 7S, fastened in the insulating mass 6 and ending with the contact ring 23, to which ring the end of the thread 2 is attached (Fig. 7).
