MECHANICAL MOVEIYIENT AND ELECTRIC-LIGHT SOCKET.

Specification of Letters Patent.

Patented Dec. 3,1912.

Original application filed December 30, 1911, Serial No. 668,632. Divided and this application liledf'llrch To all whom it may concern:

Be it known that I, ToNJEs AUGUST CARL BOTH, a citizen of the United States, and a resident of Malden, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Mechanical Movements and Electric-Light Sockets,- of which the following is a specification, taken in connection with the accompanying drawing, which forms a part of the same, this application being a division lof vmy copendiug' application, Serin No. 668,632.

My invention relates to mechanical movements adapted for' universal application. Further to: electric light sockets and to certain details of construction of both the mechanical movement and the electric light socket, which will be more fully hereinafter described in the specification and pointed out in the claims.

I have shown my mechanical movement as afswitch mechanism in an electric lightsocket, to which it is particularly adapted owing to its simplicity, theI few parts, and the small space occupied by them. lVhen so used it makes a quick make and a quick break of the electric current, Without arcing, upon the operation of the driving member in either direction.

Among' other advantages my mechanical movement permitsthe socket to be formed4 a switch mechanism in anelectric light' socket, but it is vto be understood, ofcourse, that the mechanical movement is not to be limited to this use.

In the accompanying drawing showing illustrative embodiments of my invention and in which thev same reference numerals refer to similar parts in the several iigures,-Figure l is alongitudinal vertical section through my electric light socket, one of the insulating members being shown in side elevation; Fig. 2 isav longitudinal vertical scction through my electric light socket, substantially at right angles to the section shown in Fig. 1: Fig. 3 is a side elevation of the screw shell; Fig. 4 is a plan view of the screw, shell 21 is Serial No. 687,183.

screw shell; Fig. 5 -is a perspective .View of vone form of resilient driven member, the parts being shown disconnected; Fig. 6 is a perspective view of the preferred form of driving member; Fig. 7 is a plan View of a blank from which one form of driven member may be formed; Fig. 8 is a side elevation of the driven member formed by bending the blank illustrated in Fig. o horizontal section substantially on the line 9-9 of Fig. 2; Fig. 10 is a fragmentary sectional view showing a detail. i

In the illustrative embodiments of my invention shown in the drawing, 1 is an electric light socket formed of two complementar)v insulating members 2 and 3 having meeting surfaces 4, l, Fig.

the electric lightsocket, though portionsl of the meeting surfaces are preferably offset as at 5, Fig. 2. These insulating members 2 and 3 are preferably formed from porcelain and without cross holes and each of them is l 2, which coincide. substantially with the longitudinal axis of.

7; Fig. 9 is 'a provided with a recess (3 which togetherf" form an interior recess er chamber T for,y the reception of my mechanical movement 1 when it is used as a switch mechanism in this form of electric light socket. Each of the recesses (3, 6 has an offset or deeper recess S', F ig. 2, which form guides :for the otl'setportions t), 9, Fig. 5, or 10, 10, Fig. 7, of the respective resilient driven members 11 and l2. I also form in theroii'perating faces of each of the insulating members 2 andB, two demi-circular openings 13, 1l to receive the respective cams 15 and 1G carried by the driving member 17. The holes or recesses 1S. 18, Fig. 2 are also molded in the insulating members 2 and 3 for the reception Cf the bearings 19, 19 of the intermediate er movable hill and valley member 20. l attach the insulating membersQl and P to a lamp holding member which is usually, though not necessarily, in the form of a screw shell 21. The upper portion of the provided with a lip 22,' Figs. 1, 3 and 4 which extends up into the interior chamber i' and forms one contact. l also prefe ably provide the head of this screw shell Q1 with a dovetail 23 to ccperate with the dnvetails 24, 2-1 formed in-the relspective insulating members Q and I also preferably provide each cf the insulating members 2 and 3 with another doretail 25, Fig. 1, which takes under the head 26 of the screw shell 21. In this form of' my invention the intermediate or movable hill and valley member is formed of some insulating material andprovided at each end with' :i 'valley 28,-each yalley having a ledge or shoulder 29 and' a boot, kicker or accelcrater 30. The hill l 31 is that portion of Fig. 5. hierin these engaging surfaces and Sllas hook on one member and a slot 2o" the other', the particular forml of engaging surfacesv shown, however, are merely by 'ivay of example. The stamping 131 which fl. will refer,1 to as e' shoe, is preferably,

' `instead .of using a resilient member Yform-ed of .n plurality et parts, I may in seine cases use a resilient member termedl though notA necessarily provided with the Aoffsets 9, '9.' rlhe upper stamping 32 is pro! videdvwith an engaging surface 35 to'eooperate with the Amovable intermediate or hill. and valley member20. On assembling the 'shoe 131 and the member 32,v a very strong resilient member 11 lis termed.

. out ot one piece of material. l have shown such a. resilient member in Figs.

l and 8.

- ln this toi-m, the blank 36, Fig. 7, is preti' which would lie et' the `#anni erablyprovided wftli the otsets 10, 10- and Aalso with one or more ribs 37 37 which serve to strengthen the resilient member 12 when the blanli is bent backv on itself, Fig. 8. In this form, the surface 38 cooperates with the intermediate hill and valley member 20.

.l have. fou'iid that it is quite desirable to insulate the hey or driving member 17 from the switch mechanism so' that a metal key or a key iorined et other conducting mitte.-l

rial 40 may bev placed upon the end 3l) ot the y driving member,

lt is often quite desirableto have the met:y lie key harmonize 'with the metal et 'the c sing or the cluster "or other insl'nllalion wi'tli'wliieh it isfilsed.

Figs. Il and 10.

Upon the rotation of the key or driving shaft 17 in either direction, the cam 15 or 16, as the ease may be, will coperate withthe insulating intermediate or hill and-valley member 20 and cause the resilient driven member 11 or 12, Whichever one is used, to store up energy by causing the two free ends of the resilient driven memberto. ap; preach each other. When suflicient lenergy has been stored up in the spring or driven member 11or l2, the kicker or accelerator 30, at 'a certain predetermined position on the rocking of the intermediate meinberQ'O,

will crowd the end' of the driven me'mf ber 11 or the end 38 of the driven inenibiqr 12 out of the valley 28 with Which it hns been in engagement sind over its adjacent resilient driven member", Whichever oriiiis used, to fly over with positive'smp "from the position shown in Fig. 1 and atthe'same time, the consuming device, Whatever'it may be, will be 'thrown into circuit bytheend 42 of the d riven member 11, oi-the end 43 `f the driven membery 12,'Wliicheverfform is used,icontacting with lthe arm elli of. the bindingpost 45 ,and with the lip 22 oli the screw' shell 21, 'the eirrentpassingthrough thev re# silient driven memberfll or 12 astheease may be. lTo disconnect the consuming device, it is merely necessary to rotate the driving member 17 ery key shaft, in either direction, when power Will be again storedl up in the ,resilient driven member until such time as! the intermediate orA movable hill and valley 1nember20 has reached sub-y stantially the position shown in Fig. 1 when the resilient driven member Will, witli'- I ouic'lr and veositive snap, tly over ,to .the posi`- tion in which it'isishoyvn in Fig. L1, When the 'current Will be ydisconnected instantaneously 'and yWithout aireing. It Will be further noted lthat the Aintermediate member 20, Vin Apresent invention., serves as ii partA of the mechanical movement and" in addition asan'v insulating "member to insulate abortion of the mechanical movement from another `nor'- tion. in the form"shown,'by Way olifex ample, the' insulating intermediate member 20 serves to insulate the'key shaft or driving member 17 from the drivenfmember'll vor 12 Whiehever is used. f i

'The biiu'ling post 4T is secured `in any, suital'ile .inaiinerto. theI insulating base, preter- This Will thenv cause thev entire' fi 'ably by means of the screw 48. The binding post 47 is provided with the binding screw 49. The other binding post 45 is provided withv a similar binding screw 50. 5 The binding post 45 is secured to the insulating base by the screw 51 which also Serves to hold the two insulating members 2 and 3 together. i To guide t-he resilientmember l1 or l2.l I preferably bring the walls 52, 52 of the recesses 6, 6 up adjacent to the spring member; The offsets 9, 9 or 10, 10 are received in the enlarged or deeper recesses 8, 8,- the shoulders 5B, 53 serve as an additional precaution and act asstops to prevent the driven member 1l or 12, as the case may be from snapping over too far to the right of F ig. 1.v Ordinarily this movement will -be ylimited by the end 35 or l38 contacting .with the elevated valley 28 of the intermediate meinber 20. Should there, however, lbe any tendency to an excessive lateral move- Y ment, the shoulders or stops 53, 53, Fig. 9, will prevent it. lVhile my invention is adapted and is preferably to be used with a socket shell and a socket cap to surround my electric light Socket, the shell and .cap :formv no part of my present invention and are omitted. Such l3o a surrounding shell and cap are well known in the art. A cap andshell are 'illustrated in my' companion application Ser. No. 6168,632'oiwhich this is al division. y'Having thus described this invention in connection with the several illustrative emb odiments lthereof to the details of which I do not desire to be limite d,.what is claimed 'as-v new an'd what it is desired to secure by Letters Patent is set forth inthe appended 40 claims.
