Referring to the drawing, the electric switch embodying the present Vinvention as applied to a'pull socket 'fixture preferably comprises a two art base block, the parts of which are. suit-ab y, connected. One part ofI the base block is indicated at' 10 and the other part of the base block is indicated at 11. These base block membersas will rbe understoody may be made of porcelain or any other suitable insulating ,material.- As illustrated, these base block members-are connectedin spaced positions by a bracket 12.' One arm 13 of this bracket 12 is connected by screws or otherwise tol the base block member 11` and the other arm 14 of thc bracket is connected to the base block member 10 in the same manner.

In the arm 14 and preferably in the central portion thereof there` is a pin or bolt 15 which extends outwardly therefrom toward the base block member 11. Mounted so as to turn freely on the bolt 15 there is a collar 16 withv which the movable members of t-he switch are associated. One of these members is a driven member indicated at 16 and carries the movable contacts of the switch mechanism. This driven member 16 is provided centrally with an aperture 17 adapted to fit over and to be received upon the reduced inner end of the collar 16 as is clearly indicated in Fig. 19. and this driven member 16 is also provided with a recess 18 which is substantially concentric with the aperture 17. The driven member 16 also includes an angular portion 19 adapted to extend into the recessed part 20 of the base bloc-k member 10. and at the extremity of the angular extension a plate 21 of suitable insulating material is secured by means of rivets 22 or otherwise. The outer edge of the plate of insulating material is preferably made on the arc of a circle and is provided with spring contacts 23 and 24. As illustrated, these spring contacts are formed of loops of conducting material which at the turned portion is fitted into slots 25 and 26 extending radiall v into the plate of insulating material with a portion of each strip extending along the opposite surfaces of the plate of insulating material and then turned outwardly to form the movable contacts of the switch. The driven member 16 is also provided with a lug 27 in which theV corresponding ends of springs 28 and 29 are connected, these springs being a continuous piece of resilient wire as illustrated in Fig; 9. if found desirable. Furthermore, the driven member 16 includes a projection 30, which, as hereinafter described.` is adapted to cont-act with the stops 31 and 32 connected to or forming part of the transverseportions of the bracket 12 to limit and determine `the extent of the movement of the driven member 16 and the movable contact carried thereby. Also in the driven member 16 there is a small hole 33. the purpose of which will be hereinafter indicated.

Together with the driven member and the parts associated therewith as hereinbefore described, I employ a main driving member 34 which is illustrated in detail in Figs. 11 and 12. The main driving member 34 is preferably made of thin metal and centrally is provided with an aperture 35 adapted to fit over the reduced outer end of the collar 16. and the main driving member is preferably connected securely to this collar 16 in any suitable manner soas to turn therewith. In suitable positions this main driving member 34 is provided with arms 36 and 37, in the edges of which there are' respectively the recesses 38 and 39. The main driving member 34 is also provided witl1 an angular extension 40, the extremity of which lies parallel to and spaced from the body of the main driving member and is provided With a small hole 41. Associated With and connecting the driven member and the main Adriving member 34, I employ al spring 42, 7 preferably having a loop coil 43. One end of the spring 42 is lixed in the small hole 33 in the driven member 16 and the opposite end of the spring 42 is fixed in the small hole 41 in the main driving member 34 so that the spring is made to oscillate on an axis which is perpemlicular to the movement of the driven member 16 and the main driving member 34, the action being such that when the main driving member 34 is oscillated through a predetermined portion of a revolution in one direction, sufficient. tension is applied to the spring 42 to cause a quick snap oscillating movement of the driven member through a corresponding portion of a revolution, the movements being such that when the main driving member is oscillated clock-wise, the driven member carrying the movablel switch contacts is oscillated counter clock-wise and vice versa.

In the structure as shown 4and described, I also employ an auxiliary driving member 44 illustrated in detail in Figs. 7 and 8. This auxiliary driving member 44 is also made of thin metal and is provided adjacent one end with an aperture 45 of substantially the same diameter as the aperture 35 in the main driving member 34 so as to bereceived on the reduced outer end of the collar 16 and to lie against the outer face of the main driving I member and to turn freely on the collar.

At the end opposite that in which it is pivotally connected, the auxiliary driving member' is provided with a bracket 46 which is notched as indicated at 47 to receive the end 110 'of a pull chain or cord 48 by which, as hereinafter described, the movable parts of the switch are operated by pulling and releasing the chain or cord. 'Ihis auxiliary driving member is also provided with a tongue 49 115 extending from t-he reverse face thereof and provided with slots 50 and 51 as Well as a ,f notch 51. The slot 51 is adapted to receive the free end of the spring 28 and the. slot 50 to receive 'the free end of the spring 29, in 120 order `that through the action of these springs, the auxiliary driving member is returned and normally maintained in its operative position. y

The movable parts of the switch mechanism also include an actuating member 52 which is shown in detail in Figs. 5 and 6. This actuating member is also preferably made of thin metal and is provided in the required position with an aperture 53 of the 130 h collar.

l periphery of the sleeve 35` whic same diameter as the apertures in the main and auxiliary driving members so as to also be received on the reduced outer end of the collar 16 with the inner face of the actuating member lying against the outer face of the auxiliary driving member sothat the actuating member is also free to turn on the Furthermore, as indicated in Fig. 19, the outer reduced end of the collar 16 may be upset against the outer surface of the actuating member 52 so as to maintain the same and the auxiliary driving member 44 in position on the collar. The actuating member 52 also includes shoulders 54 and 55 in oppositely 4disposed positions .as well as a shoulder 56 at the end of the member opposite the shoulders 54 and 55. erating parts of the switch, as hereinbefore described, are in their `assembled positions, the driven member (is appreciably spaced from the main drivin member by a portion acts as a spacer and the reverse side of the auxiliary driving member lies against the obverse fac-e ofthe main driving member with the tongue 49, the auxiliary driving member extending over the main driving member, a` portion of the 0f the latter lying within thelnotch 51 of the former so as to maintain the parts in their associated relationship. The reverse side of the actuating member 52 also preferably lies against the obverse face of the auxiliary driving member with the shoulders 54 and 55 spanning the auxiliary driving member and lying against the obverse face of the main driving member, while the shoulder 56 extends beyond the edge of the main driving member and its opposite ends, that is the opposite ends of the-shoulder 56 are adapted to engage alternately in the notches or recesses 38 and 39.

Suitably fixed in .the base block member 10, there is a stationary contact 57. This is preferably secured in position by a screw or bolt 58 passing through the reduced section of this base block member and connected electrically with a screw socket 59. Also connected to the base block member 10 within the screwv socket 59 and at the base thereof as is customary, I employ a central contact member 60. This central contact member 60 is electrically connected to a stationary contact 61 which also passes through the re duced part of the base block member 10 and secured a terminal 63 fitted with a screw binding post 64 and the terminal 63 is electrically connected to a stationary contact `65 by means of a contact bar 66 or otherwise.

e stationary contact 65 is disposed oppo- Th sitely to the stationary contact 57 so that in When the opone position the movable contact 24 simultaneously engages both the stationary contacts 57 and 65. Also mounted in a recess provided therefor in the periphery of the base block member l() is a terminal 67. This terminal 67 is fitted with a screw binder post 68 and is electrically connected to a stationary contact 70 by means 4 of a contact bar 69 or otherwise. The stationary contact 70 is oppositely disposed to the stationary contact 61 so that in one position the movable' contact 23 is adapted to simultaneously engage both the stationary contact 61 and the stationary contact 70. The longitudinal recess inwhich the terminal 63 is mounted is indicated at 71, and the longitudinal recess in which'the terminal 67 is mounted is indicated at 72, and as will be understood, these recesses are sufficiently deep to receive the terminals and their screw binding posts so as to connect the lead wires thereto and set the binding post in-position without interfering with the shell or cover which may be employed with the switch when used in a socket or other apparatus.

Also. as illustrated in the drawing, the switch mechanism as employed in a socket may be fitted with a shell or cover 73 which is provided with a chain guide 0r conduit74 through which the pull chain 48 passes and is available for use.

Assuming the parts of the switch mechanism as hereinbefore described to be in the position shown in Figs. 1 and 2, it will be observed that the contact carrying member, that is to say, the driven member 16 is in theposition with the movable contacts and 23 therein respectively against the stationary contacts 57 and 65 and 61 and 70. In this position the projection 30 bears against the stop 32 carried by the right hand postof the bracket as viewed in Fig. 1. It will also be observed that the main driving member is in that position in which the arm 37 bears against the same post 12, and that the outer end of the auxiliary driving member lies at the left of the central axis as shown in this figure and contacts with the shoulder 54 of the actuating member 52. Now by pulling on the chain 48, the auxiliary driving member is caused to oscillate in a counter clock-wise direction carrying with it the actuating member 52. The continued movement of these members by pulling on the chain brings the end of the shoulder 56 into engagement with the notch 39 in the main driving member so 'that by the further movement of the auxiliary driving member and the actuating member, the main driving member is caused to oscillate in a counter clockwise direction against the action of the spring 29, `and when this movement has been continued suficiently far, the tension applied to the spring 42 is increased until.

it becomes sufficient to actuate the driven member and the contacts carried thereby in a vclock-wise direction and with a quick snap action so as to remove the movable contacts` from the fixed contact. lVhen this movement has been completed and the chain released, the spring 29 returns the auxiliary driving member and thel actuatmg member to a position on the other side of the central axis as shown lin Fig. 1 so that the parts are adapted` by pulling on the chain, to be moved in the opposite direction to cause the driven member with the contacts carried thereby to be moved againwlth a quick snap action into contact with the stationary contacts, or in other words, to be returned to a position of the parts as shown in Figl, it being understood that the stops 31 and 32 limit the respective movements ofthe driven member by the projection 3() coming in contact therewith, while the posts forming part of the bracket limit the movement of the main driving member by the arms 36 and 37 coming into contact therewith, and also that the return movement of the auxiliary driving member to the position shown in Fig. l is caused by the action of the spring 28.

By reference to Figs. 13 and 14, it will be seen that the upper or outer block 11 of the base block is provided with a recess 75 which is so placed as to lie centrally over the outer end of the auxiliary driving member 44, that is, when the auxiliary driv' ing member is in its Central position, the notch 47 therein lies immediately under this recess and as the auxiliary driving meniber is never normally stopped in this position, that is normally it is always at one side or the other of this central position, and as the bracket 46 lies in close proximity to the under surface of the base block member 11, the pull chain member 48 may be placed in position in the notch 47 by holding the auxiliary driving member in its centrali position, and in the same position it may be as readily moved from the notch. In view of this structure as will be apparent, the base block member 11 coacts with the bracket 46 to maintain the pull chain in position in the notch in the bracket.
