T (ZZZ whomizf may concern:

Be it known that l, CARL RUDOLPH linens,

a citizen of the United States, and o resi-v dent of Ozihlnni'l, county of Alameda, and State of California, have invented a new and useful Electrical Switch, of which the following is e specification.

The present invention relates to iniprovo ments in electrical switches and its psrtic r ltl object is to provide at switch particularly adopted or giving direction indicating signals in connection with motor vehicles. While designed for this purpose, it may however, be used in many different ways and would be particularly adapted for z1dvertising signs and the like calling for :1

individual lights. It is proposed in the pres ent invention to use :i planetary SjYStG-Ill for establishing electrical connections between various contacts. Further objects and odtnntng of my invention will appear as the s nciticstion proceeds.

The preferred form of my invcntion is illustrated in the accompanying drawing in h Figure 1 shows a plan View orv my ch, Figu. 2 a plain View with the cover :1, horizontal section through the same taken along line 3-8 oi? Figure 4;; Figure at a side View of my planetary switch; and Figure 5 a vertical section through the same taken along line 5-43 of Figure 1. While Ihove shown only the preferred form 01 the invention, lwish to h 1' so it understood that various changes modifications may, be made Within the I of the clsinishercto attached Without from. the spiritof the invention. i Mancini-y switch coniori. s a (rise :3) preferably cylindrical inrorrn and made of bnliel c or some similar insulating inter or-1y with s coir- 1st to the two segniens i? and (3: one ted to have or lid Q '1 secured the by inczins oi screws 0 H at the 1 lid is subsdri'n 1y flush with the oso. The center of the case is occupied. by :1 drive gem {T} mode of bnkelitc or some similar. insulating material and so cured on 11 control )in adapted to berotated by means oil? :1 handle (9) provided on the on oi" the case.

Section (11) is permanently s cured i means of screws (6") to ring segment (a) and case (2) exteriorly; sections (12), (13),:1nd (Ir-l) are permanently secured to the ring segment 3) and held against rotation by the pin (18) also permanently secured thereto. The

pin (1.8) mounted with freedom of radial motion in the perforation (15) of case (2) and conveys freedom. of parallclmotion to all points it segment (3) and sections {12 (13) and (14). Tlho springs (19) are so arranged that when octing'together upon sections (13} and (let) the force resultant acts in the same plane and parallel to the radial motion of the pin (18}. I have in my planetary-switch provided both factors absolutely necessary, namely, "uniform pressure in uniform direction of application. The section (11) is the largest one and occopies more than onelmlif of the iiolc'internul gear, while the section {12) is the smallest one and is arranged diametrically opposite to the central portion of section (ll). The sections and (1 1-) are interposed between the sections (11) and (12) on opposite sides of "the letter. All four sections sire insulated from one another as shown at (16), preferably by on air The large section (ll) is connected with a source of electrical energy by means of the binding post (17) extending through the case into the said section. This section (11) will be referred to es the live section. The section (12) does not communicate withany port on electrical circuit and may, therefore, be ed es the deed section. The two s ctions (13) and 1%.) here incite]: referred to as the contzictsections, make contact through sgfiiings (19; with. plates (21) which l t ter metallic connection with binding; posts (22), which lattcr form parts of two different light cir cuits.

Between tie crive vol 'ing motion and equidistant from one another. It will be seen that when the drive near (1 i :otatcd by means of the handle (9) the pinions revolve between the two gears and will estoblish elect-r col corn nections betv'een d erent sections of the internal "car due the fact that the three pinions are electrically connected by means of the retaining rings In the position shown in Figure 3, the pinions (25) and engage the live section (11), while the pinion the dead section (12). Since the latter for-ins no part of an electrical circuit, no current flows and the switch may be said to be in neutral. ll' the drive 7) is turned to the right the two pinions and remain in con tact with the live section (11) While the pinion engages with the contact section (13), thereby closing the circuit of one light. it turned to the left the pinion makes similar contact with the section (l-l) and thereby closes the circuit actuating the second ligl'it. If turned slightly further, either to the right or to the left sufliciently to bring; the handle in reversed position one of the pinions or shall occupy its position central as to the live section (11), the other pinions contact both sections 13) and (14;) actuating both circuits and. lighting both. lights. When rotated continuously sequences of no light, one light, both lights, other light, no light result, one sequence to each complete turn of the drive gear ('7 is the rate of the sequences. turn oi? the drive gear corresponds to three complete turns of each pinion and only two of the pinions make two actuating contacts each, reducing the friction contact Wear to a minimum. An evident further advantage is due to the superior, yes almost perfeet balance of movable parts in stable equilibrium, which no outside movement or joltiug disturbs, provided the two arms of the handle (9) and are balanced in length and Weight. T he natural gear trio tion assisted by the uniform, parallel. pres sure of the springs (19) resists all casual and most scc'dcntal rotary impulses applied to the central pin While the intended impulse e15 the lingers of the operator is easily and smoothly obeyedleavin;', at the end. of it, all par s and all contacts just Where the impulse placed them.

For the proton-ml form of my iirvcutii'm the teeth number ll-812* 12 making a dianr eter ration of 1 because the four main points of the compass seem eligible as to a vihiclc direction indicator which demands forward, backward, ri ht and left course signals and therefore four main, true signaling positions of the operating lever.

For other forms such as applied in construction of recording spcedoineters or of flashers in display electric light signs or of automatic controllers where other clcctro-dynzunic currents are to be shunted the above mentioned elements of construo tion n'iay be multiplied Within certain limits. .hor example there may be teeth to the internal gear, 36'

teeth to the drive gear and 12 teeth to each pinion with rrespending changes in the number of nious and of contact sections. In this case there would be a maximum. of five primary positions of the control-lower. It is suiiicient to indicate the possibility Without going too far afield in these speci fications.
