MECHANICAL MOVEMENT AND ELECTRIC-LIGHT SOCKET.

Patented 0a. 1,1912.

Application filed December to, 1911. Serial no. 668,632.

tain 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 a switch mechanism in an electric light socket, to which it is particularly adapted owing to its simplicity, the few parts, and the small space occupied by them. When 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, whether this driving member be a rotary or a reciprocating one.

Among other advantages my mechanical movement permits the socket to be formed smaller and stronger for the opening in which the mechanical movement is mounted need not be so large as for other switch mechanism. In illustrating my invention I have, therefore, by way of example, shown it as a switch mechanism in an electric light socket, but it is to be understood, of course, that the mechanical movement is not to be limited to this use.

In the accompanying drawings showing illustrative embodiments of my invention and in which the same: reference numerals refer to similar parts in the several figures,- Figure 1 is a central vertical section through myelectric light socketequipped with my mechanical movement as a switch mechanism; Fig. 2 is a side elevation, partly broken away, of the electric light socket shown in Fig. 1, the cap and easing being, omitted forthe purpose of clearer illustra- 1 looking down in the direction of the arrows; Fig. 4 is a longitudinal vertical section substantially on the line 4-4 of Fig. 1 looking in the direction of the arrows; Fig. 5 is a horizontal section substantially on the line 5--5 of Fig. 4;.

Fig. 28 is a plan view of the intermediate or hill and valley member. of Fig. 24; and Fig. 29 is a side elevation of the inm termediate or hill and valley member shown in Fig. 28.

In the illustrative embodiments of my invention shown in the drawings, 1 is an electric light socket formed of two complementary

insulating members

2 and 3 having

meeting surfaces

4, 4, Fig. 2 which coincidesubstantially with the longitudinal axis of 7 the electric light socket though portions of the meeting surfaces are preferably offset as at 5 in Fig. 4. These insulating members 2 .and 3 are preferably formed from porcelain and without cross holes, and each of them is provided with a recess 6 which together orm an interior recess or chamber 7 for the reception of my mechanical movement when it is used as a switch mechanism in this'form of electric light socket. Each of the recesses 6, 6 has an offset or deeper recess 8, Figs. 2, 3 and 4,.which form guides for the

offsetportions

9, 9, Figs. 2, 5 and 10, of the resilient driven member 10. I also form in'the 006perating faces of each of the

insulating members

2 and 3 two

semi-circular openings

11 and 12 to receive the

respective cams

13 and 14 carried by the driving member 15. The recesses 16, 16', Fig. 3, are also molded in the surfaces of the

insulating members

2 and 3 for the reception of the

trunnions

17, 17, Fig. 6 of the intermediate or movable hill and valley member 18. I attach the insulating

members

2 and 3 to a lamp holding member, which is usually, though not necessarily, in the form of a screw shell 19. The upper portion of this screw shell 19' is provided with a lip 20, Figs. 7, 1 and 4 which extends up into the interior chamber 7 and forms one contact. I also preferably provide the head of this screw shell 19 with a dovetail 21, Figs. 8, 7 and '9 to cooperate with the

dovetails

22, 22, Fig. 2, formed in the respect1ve insulating

members

2 and 3. I also preferably provide each of the insulating

members

2 and 3 with another dovetail 23, Fig. 1, which takes under the head 24 of the screw shell 19.

The intermediate or movable hill and valley member 18 is provided at each end with a valley 25, each valley having a ledge or shoulder 26 and a boot, kicker or accelerator 27. The hill 17 0 is that portion of the intermediate member which connects the two valleys, Figs. 1 and6.

The preferred form of resilient driven member is formed from a stamping. A

metal and provided with strengthening

ribs

29, 29, which are preferably rolled, stamped or otherwise formed. I also preferabl provide the blank with

offsets

9, 9, one en 43 of the blank being preferably slotted by the slot 31, Fig. 10. 'When this blank 28 is bent back upon itself, the resilent driven member 10 is formed, one end being further prefer-,

ably bent back upon itself to make an engaging arm 32, Figs. 1 and 11, which is adapted to be received in 'the

valleys

25, 25 in the intermediate or movable hill and valley member 18,'and to cofiperate with the ledge 26 and with the boot, kicker or accelerator 27 in a manner to be hereinafter described Front the mechanism so far described, dealing more particularly with the mechanical movement, the rotation of the driving member 15 in either direction will cause the

cams

13 and 14 to operate the intermediate member 18 and through it operate the driven member 10 converting a slow or fast rotary motion into a uick and positive reciprocating motion. n the position of the parts shown in Fig. 1; the rotation of the driving member 15 in either direction will cause the cam 13 to coiiperate with the raised end of the intermediate or movable hill and valley member 18 which will cause thismember to rock upon its trunnions 17," 17 held within the

openings

16, 16 in the respective insulat-' ing'

members

2 and 3. The rockin of this member will cause the two separate ends of the resilient driven member 10 to approach each other and thereby store up energy in this member 10. I I preferably so form the

valleys

25, 25 in the member 18, and more particularly the relative' locations of the ledges 26 and accelerators 27, that at the first portion of the rocking movement of the member 18 the ledge 26, Fig. 1, will prevent the end 32 of the resilient member 10 from escaping from the valley 25 within which it is then engaged. Further downward movement of the cam 13, upon the rotation of the driving member 15 in either direction, will store up additional. power in the resilient member 10 which will have its end 32 held within the valley 25 until such time as the maximum energy shall have been imparted to the spring 10 up to which point the ledge 26 will have held the end 32 from escapement. When, however, the predetermined amount of power in the spring has been reached the rotation of the intermediate member 18, upon its own axis, will have brought it into substantially the osition shown in dotted lines in Fig.1 w en the accelerator or kicker 27 will crowd or kick it out of the valley 25 and over the ledge 26. The resilient driven member 10 will then instantly with a quick sharp snap, slide up the inclined intermediate hill of the hill and valley member 18 until its end 32 engages with the elevated. or raised valley 25.. In

direction, I raised, will causethe end of the member 18 clined surface with which it coiiperates to be depressed and this will store up energy in the resilient 'member 10 until such time. as/ the end 32 is pushed, kicked or crowded by the accelerator- 27 out of the valley 25 at that end of the member 18 and over its ledge 26 when theend of the spring 32 will instantly, with a? quick and positive snap move up the in 170 of the member 18 until the end 32 is caught in the valley 25'. At the same time that this surface 32 is moving up the snaps over instantly into its opposite position, that shown in full lines in Fig. Continued rotation of thedriving member 15, in either direction, will cause the driven member 10 to reciprocate with a quick and positive snap.

This mechanical movement may be used wherever itis desirable to employ such a device. V J I have illustrated this mechanical, move-' ment as a switch mechanism in an electric light socket. When so employed upon the rotation of the driving member 15, which 1 in the form of the invention shown and holds them together.

in Fig. 1 is .a key shaft, in either direction, the resilient driven member 10 will make a quick make or a quick break of the electric current without arcing, due to the fact that this driven member 10 reciprocates with a quicksnap. In my improved electric light socket, the lip 20 of the screw shell 19 is preferably formed integral with the screw shell and bent up in the POSI- tion shown in Fig. 7. In assemblin the two insulating members2 and '3 this 'ip 20 extends up into the chamber 7 formed between the insulating

members

2 and 3 and is one of the contacts as shownin Figs. land 4. A groove 171, Fig. 5, preferably formed partly in each of the insulating

members

2 and 3 ermits the parts to be more readily assembled. I also employ a binding post 34 having a bent arm 35 which extends within the chamber 7 and adjacent, but separated from, the lip 20 of the screw shell 19, Figs. 4 and 5. This binding post 34 is provided with a binding screw 36 and cooperates with a lockingiscrew 37, Fig. 4, which passes through the two insulating

members

2 and 3 This single locking screw 37 not. only holds the binding post 34

tothe insulating members

2 and 3 and holds the two insulating members together,

but also holds the screw shell 19 to the ind other bin mg post inclined hill 1700f the member 18, the entire resilient member 10 moves orstantaneously and without arcing.

bent arm,39, Fig; 4, which extends through .an opening in the screwshell 19 and becomes the center contact ;of the electric light socket. This bindingpost :38 is secured to r 3 in'- any suitable the insulating mem manner such as by means of the screw 40 which seated in.the opening 41. With the particular arrangement shown, h screw 40 is caused to engage with the binding' 'post 38 before the two insulat' r member2 and 3 are assembled. This binding post is also provided with a binding screw Upon the rotation of the-keyv or driv- 42.. ing shaft 15 in either direction, the

cam

13 or 14, as the case may be, will cooperate with the intermediate or bill and valley member 18 andlcause the resilient driven member 10, which is formed of some con-. ducting material, such asv metal, to'sto're up 38 isprovid'ed with a energy in the manner previouslydescribed.

When sufiicient energy hasbeenstored 11p vin -the sprlng or driven member -10, which wlll be about when the driven -member reaches the position shown in dotted lines in Fig. 1, the kicker or accelerator 27 will crowd the end 32 of the resilient driven member out of the valley 25 and over its ledge 26. This will then cause the entire resilient driven member- 10 to fly over with a positive Fig. 1, and at the same time, the consuming into circuit by. the end 43 of the resilient member 10 contacting with thearm 35 of the binding post 34 and with the lip 20 of the screw shell 19, the current passing through the resilient driven member 10. :To disconnect the consuming device, it is merely necessary .to rotate the driving member 15 or key shaft, in either direction, when power will be again stored up in the-resilient driven member until such time as the intermediate or movable hill and valley. member 18 has reached substantially the position shown in full lines in Fig. 1, when the resilient driven member 10 will, with a "quick and positive snap fly over to the po sition shown in full lines in Fig. 1 when the current will be disconnected or broken in- To guide the resilient member 10 I preferably bring the

walls

44, 44 of the recesses snap from the position shown in device, whatever it may be, will be thrown 6, 6 up adjacent to the spring member 10, Figs. 2 and 4. The

oifsets

9, 9 of the spring member 10 are received in the enlarged or

deeper recesses

8, 8, the

shoulders

45, 45, Fig. 5, serve as an additional precaution and act as stops to prevent the driven member 10 from snapping over too far to the right ofv Fig. 1. Ordinarily this movement will be limited by the end 32 contacting with the elevated valley 25 of the intermediate mem- .I have found in 1 8, as shown in Fig. 1. Should there however, be any tendency to an excessive lateral movement, the

stops

45, 45,'Fig. 3,

'will prevent it.

The end of the driving member 15is supported betweenthe insulating

members

2 and 3 in any suitable manner, such as by means of the bearing 46, Figs. 1 and 3.

v ""The' intermediate member 18 which I have not employed. They prevent the metal, un-

der excessive use, losing its resiliency.

The insulating

members

2 and 3 and the screw shell 19 are surrounded with a. casing 47 having an interior insulation such as the fiber lining 48, Fig. 1. The cap 49. is preferably providedwith one or more punched or

other openings

50, 50, Fig. 1, the insulation 51 having one or more punched

teeth

52, 52 to snap into the openings 50 in the cap 49. This is a very cheap and serviceable manner of assembling and attaching the cap and insulation together. Instead of forming openings in the cap I may form in the cap'53 one or more indentations 54 for the reception of the punched up finger 55 in the ber insulation 56, Fig. 6. v

The driving member may be formed in various ways. Preferably I form it from a stamping 156, Fig. 12, having the

arms

57, 57 which are bent back upon themselves forming the

cranks

13 and 14, Fig. 13. Instead of this form, however, I may form the driving member 157 from wire or similar material, Fig. 18,-and bend it to form the

cams

58, 59. ther various ways of providing the driving member with cams may be employed such as for example having the driving member60 provided with two disks 61, 62 ecc'entrically mounted on the shaft or driving member, Fig. 14.

In some cases I may employ a resilient driven member 63, Fig. 17, without using the strengthening ribs member shown in this figure being substantially the same as that illustrated in Fig. 11 with the exception that these strengthening ribs are not employed. I have also found in practice that a very .desirable resilient member is one which can be formed from a plurality of stampings. I have shown such a member disassembled in Fig. 16 in which the shoe 64 is formed from one stamping and providedwith the

offsets

65, 65 and with a hook 66 which fits in an opening 67 in 29, 29, the resilient the arm 68 of the upper member 69 which is provided withan engaging surface 70 to cotiperate with a movable intermediate or hill and valley member such for example as 18 in Fig. 1. On' assembling these two spring members a strong two-part resilient driven member 71 is formed such as illustrated in Fig. 15. v

n many instances I have found thatit is Finite desirable to insulate the key or driving *cmlier 15 from the switch mechanism so that a metal key or a key formed of other conducting material may be placed upon the end 72 of the driving member. It is often quite desirable to have the metallic key harmonize with the metal of the casing or the cluster or other installation with which it is used. With such a device a key may be placed upon the end 72 of the driven member which would be of the same material and ornamented in the same way, if desired, as the metallic casing or installation, or some other metal may be used to make the key which would blend with color scheme. I have shown such a construction in Fig. 15 in which the intermediate or hill and valley member 73 is formed of porcelain .or other suitable insulating material and rocks upon the pivot 74 held Within the two-part insulating base. This insulating member is provided with

valleys

75, 75, kickers or accelerators76, 76 and ,with

ledges

77, 77 in all respects substantially similar to the corresponding element of the intermediate member 18, Fig. 1; its operation, upon the rotation of the driven member 15 in either direction, being the same causing the electric current to be made or broken with a quick snap and without arcing by having the shoe 64 connect the contact (not shown) with the lip 20 of the screw shell 19. The current is disconnected and the entire resilient member 71 forcedto the right with a quick and positive snap and without arcing the current by further rotating the driving member 15 in either di-' rection in the same manner as previously described in the other construction.

. My mechanical movement is also adapted to be used with a push button switch. My invention comprises such a device and, further, an electric light socket in which two push buttons are located adjacent to each other and on the same side of the socket. In 19, 20 and 21, I have shown such a construction. Here the insulating member is formed also of two

complementary parts

78 and 79 each of them being provided with recesses 80 and 81 to form an interior chamber within which my mechanical movement is mounted. The recess '81 in the member 78 is provided with two

openings

82, 82 to

receivethe push buttons

83 and 84. These buttons are provided with

shoulders

85, 85, which cotiperate with the any

particular shoulders

86, 86 in the insulating member 78 to limit the outward movement of the re-' spective push buttons. In this form I 'may use any one of my driven members such for example as 10, which will be caused to recip- By pushing in the push utton 83 the intermediate movable hill and valley member 88 will be caused to rock, in the manner reviously described for the other interm 1ate members, and will store upthe power in the driven resilient member 10, in the same manner as in the other forms, until such time as the kicker or accelerator 91 crowds or pushes the end 32 of the resilient driven member 10 out of the va1ley133 and over the ledge 92 when the entire resilient member 10 will snap over with a (puck snap and make a connection between t e screw shell contact 93, Fig. 20, carried by the screw shell 94 and the contact 95 of the bindin plost 0 1s connect the consuming device, .it is merely necessary to depress"-the push button 84:

My invention also comprises an electric light -through button extending on either si e of the socket. I have shown such a construction in Figs; 22 and socket. actuated by a us 23. In this form of my invention the driving member 102, Fig. 23, is provided with the

opposed buttons

135, 136 are provided with

137, 137 within which slide the

125, 125. By rotating the drivin member 122 in either direction, the

cran

123, 124 will reciprocate the links 125, within their grooves 137, carrying with them the intermediate or mov-.

- able hill and valley member 131. If the driving 'member 122 is rotated in either direction from the position shown in Fig. 24, the-elevated link 125 will cause the end of the plate 131 with which it cotiperates, to move down and cause the two ends of the resilient driven member 10 to approach, each other until such timeas the accelerator or kicker 133 will crowd or force the end 32 out of the. valley 150 and over the ledge 138 a of the member 131 when the spring or resilient driven member will instantly snap over with a quick and positive snap from the position shown in Fig. 24 to the left until I the entire driven resilient member has been moved to the left and its end 32 has been received in the other valley 150 of the intermediate member 131. This movement is instantaneous once the end 32 is released from the particular valley 150 with which it happensto be in engagement. The end of the member 131 which is now shown depressed will then be elevated. By then rotating the driving member 122, in either direction, the resilient driven member will be'caused to snan back into the position shown in Fig. 24.

I have shown this mechanical movement as a switch mechanism in an electric light socket in which the screw shell 140 has a contact 141, Fig. 25,. which extends within the center contact 146, WlllGh' is the opening 142 between the insulating

members

135, 136 and spaced from the contact 143 carried by the binding post,144. The electric current will be made or broken with a qluick-and positive snap without arcing so t at both a quick maKe and a quick break willbe made upon the rotation of the driving member 122 in' either direction. The screw shell 140 is cut awa at 145 so that an arm of the binding plate 14 may be inserted. This bindin plate 147 is secured to the insulating mem er 135 by means of the screw 148. The binding screw 149. is carried by the binding late 147. The binding. post 144, carrying t e binding screw 151, is secured to the insulating member 136 by 1 means of the locking screw 180 which serves preferably at the'same time to secure the two insulating
