It is to be'unuistooa, of course, that many of these prqectmns may be provided as the use to which the switchin member is to be put requires A series or 3am like contacts is also provided on each. "face of each of these disks 13. These can tacts be formed by slotting a: portion mo of said disks on three sides and punching the tongue shaped, portion Wliicli. thus tiolly severed from the piste outwardly to form vcam which will occupy plane F57 yoncl the surface of the disk. In practice, one of these series may be provided mime ciiately adjacent the circumference of the" disk "by merely cutting L-shnpe l slots in the disk new! the circumference and punching i the metal thus partly severed outWardIy aS I10 nest clearly it in oi these tmay he produces hy n'ierely punclr outwardly Witi'iout forming ercntial cut shown at .Ja.

This is acconuilished as to the outer series of contacts teaninating each of said contacts in a radially extending edge and, to the two inner of contacts, by providing radial cuts, the metal, preceding "which is projected to for the contacts. 'lhis combines with the tan ential arrangement of the brushes to produce the desired result. whereby the circuit connections may be terminated precisely the desired instant. A switch 01'? this character Will have plurality of to tary positions, in the embodiment herein shown eighteen being provided, and the contacts of the several disks should he so arranged that they will be definitely positioned under their respective brushes when the device occupies some certain rotary posithin. ObilOHSly, contacts will not in gen eral be provided in any one series tor each of the positions of the switch but only such contacts will he provided are necessary to effect the circuit changes desired. "in certain instances contacts extending over two or more rotary positions of the switch may he found desirable. This may be accomplished h forming certain of the contact segments of greater extent, as shown at 4-8 or by male certain of the "punched out contacts lon r, as shown at 4:9.

Mounted on the ledge 4 and projecting tangentially to disk position to cooperate with these series of contacts, are the Wipers or brushes 18. one for each series of contacts. These brushes are secured to an angle clip 19 by being clamped between one leg of said clip and the plate 20 by the screws 21. The clips t9 may be secured to the ledge l in any desired manner but in the embodiment herein. disclosed this is accomplished by the screws 22 which pass through openings in the ledge i and are threaded into one leg of the clip 19. Each clip is arranged to support two sets ct brushes of three each, that is the brushes adapted for engagement with the contacts formed on. two adjacent disks 13. it is to he understood, however that additional se ries of contacts on the disks l3 and corresponding hrushes may he provided, desired. The brushes provided for engagecontacts 16. 17, rcsp I u: "11x1 one or the aisle m s dixerent radial distances 5. The uppermost brush is arranged for engagement With the segmental projections at the circumference or the disks. The other two brushes of the set are so positioned that they will be adjacent to and out of engagement with the opposite side surfaces of said dislr but in such proio incity thereto that they will he engaged iyely upon rotation of the switch shaft. To more definitely position these brushes in igironiinity to the disk 13, plurality of sp' ng inenihcrs may he provided. These- )acing members may be supported in any do .ed manner but J in the present embodiment are carried by arms .4 formed integral with the plate 20.

the end of the shaft adjacent to the this member 2 a dish :15 having a cylindrical flange 526 is provide This lange may carry a scale used to indicate the Various positions assumed by the switching device during one revolution thereof. Mounted near the other end of the shaft is the positioning device shown in Fig. 3. The disk 27 non-rotatably secured to said shaft provided near the circun'rtercnce thereol. with a series of apertures 28. Arranged to coilperate Witl. the iinperforate central portion of the disk 27 is a brush and corre spondingly arranged to cooperate with the apertures 28 and the contact portions intermediate thereof is ahrush 30. This con-- struction may heused to complete the circuit for a controlling magnet by means of which the rotation. of the switch shaft is controlled and its function is to assure the complete passage of the switch from one position of rest to the neat. The disk 27 is fluted near the circumference thereof, and arranged to cooperate with this tinted portion is a roller 31 held in forcible engagement with said tinted portion by the spring arm brushes 29 and 80 and the spring arm are supported by an angle clip 33 secured to the flange at on the frame member 3 by means c the screws 85. This roller and the depressions in the edge-of the disk with which it cotipcrat/es act to bring the switch memher to its exact position of rest in case the energizing current for the controlling mag net should he cut oil'- too soon, thus exactly positioning the contacts under the brushes. it also operates to prevent accidental displacement of the switch member Mounted adjacent to the positioning device just described and the end of the shaft. is a disk as having; a plurality of sub-- stantially radially extending flexible arms 3?. Each of these arms 37 is provided at the end thereof Wi1l1' an otl'sct portion 38 to which is secured the annular disk 39 of magnetic material. Arranged with its edge acent to said disk 39 near the circumference angles thereto is a fricto the rotatable power controlling magnet -12 is lot to the isk 39 and is so arergization said disk the resiliency of its into iorcible engage dist: it) and the shaft CiLSES lo electrically be accomplished by r coilar as between these vother desired manner. Each .il disks which are mounted on are separated from each other by united placing disks or sponding; to these positions may be omitted,

thus holding the clutch magnet energized until next position of rest or interruption is cached. In drder to prevent und" e LlOn by thebrush in passing ttc'in'terruptions 28 and the conducting portions rebetween, a disk 46 of insulatt is seen ed to. one side of the byrivets or in any other desired As it o vious that many changes can be made in. the details of this invention without departing from the spirit thereof, it is to bo understood ti". at I contemplate all such diiicatious end that the invention is to be ed merely by the scope of the appended sgeevcs it, as previously de-' shaped portions formed thereby, said portions being projected beyond the surface of said disk whereby a series of contacts are formed and a brush arranged for successively engaging said contacts upon rotation of said shaft.

2. In an electrical switching device, a shaft, 3 metal disk secured thereto, a series of contact portions orojecting from the circumference of said disk, :1 second series of contact, portions projecting from the surface of said disk within the circumference thereof, and brushes, one for each series, arranged for electrical engagement with said contacts upon rotation of said shaft.

8. In an electrical. switching device, a shaft, :1 metal disk secured thereto, a series of contact portions projecting from the circumference of said disk, a second series of contact portions projecting from the surface of said disk within said circumference a third series of contact portions projecting from the .opposite surface of said dis: within the circumference, andbrushes, one for each series, arranged for electrical engagement with said contacts upon rotation of said shaf i L11: an electrical switching device, a-
