To (ZZZ whom it may concern i I e Be'it known that I, WI LIAMS. MEND N,

a citizen of the United States; "residing in the borough of Brooklyn, county of Kings, and State of New Yorlnhave invented cer'- tain new anduseful Improvements in A'ul f,

' spring7, which is interposed between the inner end of therecess '6 and the head 8 of tomatic Switch controlling Means which the following is a full and clear specific'ation. g i i I This invention relates; to automatic switch controlling means and "constitutes a divisional partfot' my co-pending application iiled December 2 nd, 1913, Serial Numberf804 224, in which'the present invention is shown in its adaptation to a system for switching on and off the illuminating lights of a vehicle. i c s.

The primary object of the present'inventi'on isto" provide an improvedconstruction and arrangement. of parts in switch-con},

trolling apparatus for. successively and periodically changing the conditions in an I electric circuit. I v

One of the objects of thislinv'ention is to providev improvedfswitch controlling apparatus which depends upon the cooperativeaction of two independentlyoperated instrumentalities jj.

Other and further objects Will appearin the specification and'be pointed outin the appended claims, reference being had to the accompanyingdrawings, in whichf I Figure 1 is a vertical section otone em 'bodiment of .my invention corresponding to the line 1%1, Fig.2, parts being shown in elevation; Fig. 2 is asection on. the line IIII, Fig. 1, parts beingshownjin elevation; Fig. 3 is a fragmentary detail showingfmeans for releasably locking the contact wheel in predeterminedpositions,parts being broken away and partsshown in section; Fig. 4 is a sideelevationfof a contact vwheel on anenlarged scale parts being shown in section; Fig. 5 'is an axial section of Fig 4; parts being broken away and parts shown in: elevation. i r

Referring more particularly to the draw-v ,ings and for the sake of convenience, con- I fining, the description to the'preferred embocliment shown thereon, a housing 1 is provided with a boss 2 as showngin Fig. 2 which carries a bolt, 3 upon which" is 'journaled the hub 4: of afcontact wheel'to be 'Jpresently described. Integralwith the hub tis a toothed wh'eel 5 adaptedlto with an annular recess 6 at one end extend ing around the bolt 3 to accommodate a the] bolt 3. The outeriend of the recess 6 isenlarged at 9 to accommodate the head Sfof thebolt, 'A sjshown in Fig- 1, a plu- .Specificationof Letters Patent. 'Pgi tgntgd Aug, 16; 1915, Original application filed messag s, SeriaLNo. 804,224. Divided and mammal filedl q'ovember rality of rigid arms 10 project radially from V the hub 1 at regular intervals. diately of said arms 10, thehub 1 is pro} vided I with a plurality of pair-sot spaced bearing lugs, 11 (see Fig. 5),.said lugs being, provided with shoulders, 12 against which the pins 13 carried by the inner ends of-the movable arms 14, abut. The inner end of each of the movable arms 14: I is pivotally mounted between the bearing lugs 11 by means of apin or rivet 15,. As shown in Figs. 2 and Sift-he outer ends of the arms '14 carry contactslti which are suitably rounded, as shown in Fig- 2, which re- .leasably engage in a hollow seat 17 formed in'a fixed contact (see, which is secured by rivets 19 to a block 20, said block being secured by bolts 21 to the wall of the housing 1. J As shown in Fig. 2, the fixed contact 18 is provided with an in- Interm'ei so I tegrally formed post 22, to whichis secured the end of an insulated wire 23, saidwire being introduced into the housing through a bushing 24. The contacts 16 on the outer endsof'the fixed radial arms 10 are suitably insulated from the hub t, so that when said contacts come into engagement with the fixed contact 18, the circuit will be brokenln.

As shown in Fig. 4:, each of the fixed arms 10 carries at its outer extremity an eyelet I 25 to which one end of a spring 26 is sc cured. The other end of said spring is secured to an eyelet 27 carried by the outer."

'100 pose of said spring being to normally and end of each of thefmovable arms 14:, the pur-' yieldably retain the pin. 13 against the shoulder 12.

The resilient action of the; spring '7 during the rotary movement of the {wheel permits the contacts [16 to move into andout of engagement withthe fixed contact l8.- During; those:1novements in which the movable arms 141 are withdrawn tlie increased tension of; theispring,

contacts. s In Fig. 2, oi the drawings is shown a block 28" which is secured to the housing 1 by means of bolts 29. integral with this block is a bracket arm; 30 which constitutes one of a pair of the same as shown in Fig 7 1; TWithin'} these bracketxarm's is reciprocably mounted 'a'bar 31' which is provided witha socket 32"at one end tovreceive the roundedextreinity of a bolt 33 which is reciprocably mounted in a socket 34: which 7 issecur'edfto the outer wall of the housing.

Interposedbetween a collar 85 on theinneri end of said bolt 33 and the end of the socket 3%, ma spring-36which normally retains the bar 31in the position shown in Fig.1; The other end or the bar 31 carries a cam roller 8? which is adapted to ride over acani block 38 carried on the outer end of radialarmf'39 which is keyed to the inner end- .of a bolt 6L0, said bolt being journal'ed inj a bushing 41' mounted inthe wall of the housing 1. A depending lever arm 4:2 is keyed to the outer end of the bolt and isada'pted to be engagedby any suit 'ableinstrumentality'for throwing the cam bloclr88 against thecam roller 37.' Suit able andeiii'cient means for retaining cam I block 88 and lever arm 42 in normal central position, are provided by a deflected arm 43 which is mounted upon a rod 4% and pro-' vided with means for resiliently supporting it against the movement of apin t5 which.

projects laterally from the radial arm 39.

A pawl 16 for transmittinglmotion from the. reciprocatory bar 31 to the rotary toothed wheel 5 .is pivotedon a pin 47 car ried bythe bar Integral lugs48on the pawl 46 serve to limit its moti'o n'in opposite directionss onthe pin &7 Said pawlisj provided with a'spur e9fwhich i'sadapted to V fit into the spaces between'the teeth 5, said teethb'eing rounded as shown-inFig. 1, tosu tably engage the spur 49 when moving. 1n one direction, and to displace said spur,

' The operation of my improved: apparatus will nowbe-readily understood and briefly described is as follows: Suppose the'circuit to .be brokenyin this case one of the fixed arms 10 will be in position 'tobringth'e in-' sulated contact on its 'outerend' against the If, under these conditions,the circuit isto be established,.. some suitable instrumentality effects an upward displacement of the plunger55.
