SOCKET-SWITCH.

Specification of Letters Patent.

Patented Sept. 3, 1912.

To all whom it may concern:

Be it known that I, WILBUR G. Pnm, a citizen of the United States, residing at Bridgeport, county of Fairfield, State of Connecticut, have invented an Improvement in Socket-Switches, of which the following is a specification.

This invention relates to electrical socket switches and has for its objects to simplify, cheapen and to generally improve their construction and mode of operation.

With these objects in view I have devised the novel socket switch which I.will now describe, referring to the accompan ing draw ing forming a part of this speci cation and using reference characters to indicate the several parts.

Figure 1 is a view partly in elevat on and partly in vertical section illustrating the construction of my novel switch; F1 2 a plan view of the lower insulating bloc and the switch mechanism, the brackets being in section and the returning spring removed; Fig. 8 a' similar view-with the operating member and the hook removed; Fig. 4 an edge view of the operating member; Fig. 5 an inverted plan view of the operating member; Fig. 6 a pe ective of the contact; Fig. 7 a perspective of the retainer; Fi 8 a plan view of the blade; Fig. 9 an on view corresponding with Fig. 8 Figs. 10, 11 and 12 plan views correspondin -W1l3b Fig. 2, the contact'and retainer and t e returning spring being removed, showing difg airts in the'operation of the switch, and g. 18 is'a section on the line 18-18 in Fig. 8 looking in the direction of the arrows.

28 and 29, each of which ,1 means for'hol rigidly secures both the screw shell and the bracket thereto.

Important features of my novel switch are an insulating operating member 33, an oscillating blade 34 and a blade retainer 35.

86 denotes the center screw with which the center contact of a lamp (not shown) makes electrical connection. In the present instance I have shown the center screw as passing through the shank of the retainer and the several parts as retained 1n place by a nut 37. It is unim ortant, however. how the retainer is secure in place, as it is not in the circuit. The upper end of the center screw is unthreaded and forms a pivot on which the blade and the o erating member oscillate. The blade is s own as resting upon the nut and the insulatin operating member as provided with a s save 38 which rests upon the blade. The operating member is actuated by means of a two-armed hook 39 to which the operating chain is connected and is provided with shoulders 49, for a purpose presently to explained, and with shoulders which enage the brackets (see Figs. 10 and 12) to imit the oscillation of said member in either direction. A s ring 40, one end of which is connected to t e hook and the other to a stud or screw 41, acts to return the hook to its normal position after each actuation. The operatinn member is provided on its upper side with pins 42 (shown in the present instance as connected and forming a yoke) which are adapted -to be engaged by the arms of the hook respectively to actuate the switch (see Figs. 10, 11 and 12). Upon the underside-of the operating member is a two-armed spring 48 which is retained in place by a'screw or stud 44 passing through itheEcoil and-the arms of which lie on oppo- Fsite sides of sleeve 38 and engage the opposite sides of a pin 45 projectin from the 'blade. This pm is also engage by shoul- 1 ders149 upon the operating member to disenggge the blade from the contact' and the retainer, as'will be more fully explained.

ETheablade is'preferably provided inits up- 30 denotes a'contact h ving electricalcon' ;per andlunder sides with coves 46. The preferred form of the con act and'retainer will bereadily understood from Fi 6 and i'h zrsspectlvelv each bein provi ed with ding the bla e. The contact is shapedto secure as much contact. surface aspossibletviththeblade and is provided with a rib 47 which is adapted to engage the groovein the upper sicle of-the blade to hold the blade in engagement with the contact until it is disengaged therefrom by one of the shoulders on the operating member. The retainer is provided with a rib 48 which is adapted to engage the roove in the under side of the blade and ho d the blade in engagement with the retainer until it is disen-' gaged by the other shoulder on the operat mg member.

The operation is briefly as follows: Starting with the parts in the osition shown in Figs. 2 and 10, in which he circuit is open and the blade is held by the retainer throu h the frictional engagement of the rib on t e retainer with a groove in the blade, a pull upon the chain will cause one of the arms of the hook to engage the pin 42 on the operating member toward the left in Fig. 10 and will move the )arts to the position shown in Fig. 11, in which it will be seen that the arms of spring 43 have been separated through movement of the operating member relative to pin 45 on the blade and the power of the .sprin is accumulating to throw the blade to t e closin position as soon as the engagement of a s oulder 49 on the operating member with the in on the blade disen ages the blade from t e retainer and the 111 power of the spring acts to swing the blade to the position shown in Fig. 12 in which it is in engagement with the contact, the contact and retainer, however, being omitted from Figs. 10, 11 and 12 for the sake of clearness of illustration. The first pull upon the chain therefore, closes the circuit. The instant the pull upon the chain is released, spring 40 returns thehook to its normal position, as in Fig. 12. A second ull upon the chain will cause the other arm 0 the j hook to engage the other'pin42 on the operating member and open the circuit again; that is, change the parts from the osition shown in Fig. 12 to that shown in ig.'-10 The operation is precisely the same in; opening or closing the circuit. -.Themovement of the o crating member by'mean's of the two-- armec hook and chain accumulates power in one arm of the spring until theblade is dis-.
