MECHANICAL MOVEMENT AND ELECTRIC-LIGHT SOCKET.

Specification of Reissued Letters Patent. Reissued Oct, 5, 1915.

Original No. 1,040,132, dated October 1, 1912, Serial No. 668,632. Application for reissue filed September-1, 1914. Serial No. 859,718.

To all whom 'it may concern Be it known that I, ToNJEs AUGUST CARL BOTH, acitizen of the United States, and a resident of Fairhaven, in the county of Bristol and State of Massachusetts, but formerly of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Mechanical lVIovements and Electric-Light Sockets, of which the following is a specification, taken in connection with the accompanying drawings, which form a part of the same.

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 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 understood, of coulse, 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,-

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 coincide substantially with the longitudinal axis of the electric light` socket thoughportions 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 form 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 offset portions 9, 9, Figs. 2, 5 and 10, of the resilient driven member 10. I also form in the coperating faces of each of the insulating members 2 and 3 two semicircular openings 11`and 12 to receive the respective cams 13 and 14 carried vby the driving member 15. The recesses 16, 16 Fig. 3, are also moldedv in the surfaces of the insulating members 2 and 3 for thepreception 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 av screw shell 19. The upper portion of this screw shell 19 is provided with a lip 20, Figs. 7, 1 and Ll 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 coperate with the I dovetails 22, 22, Fig. 2, formed in the reley member 18 is provided at each end with ledge or shoulder 26 and a boot, kicker or accelerator 27. The hill 17() is that portion of the intermediate member which connects the two valleys, Figs. 1 and 6a.

The preferred form of resilient driven member is formed from a stamping. A blank 28, Fig. 10, is stamped from sheet metal and provided with strengthening ribs 29, 29 which are preferably rolled, stamped or otherwise formed. I also preferably pro* vide the blank with offsets 9, 9, one end 43 of the blank being preferably slotted by the slot `31, Fig. 10. When this blank 28 is bent back upon itself, the resilient driven member 10-is formed, one end being further preferably bent back upon itself to makean in the intermediate or movable hill and val-v ley member 18, and to coperate with the ledge 26 and with the boot, kicker or accelerator 27 in a manner to be hereinafter described.

From 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 1l to operate the intermediate member 18 and through it operate the driven member 10 converting a slow or fast rotary motion into a quick and positive reciprocating motion. -In 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 coperate with the raised end of the intermediate or movable hill and valley member 18 which will cause this 'I `rocking'of this member will cause the two separated ends of the resilient driven member 10 to approachl each other and thereby store up energy inl this member 10. 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 valley25 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 2G will have held the end 32 fromA escapement. lVhen, 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 position shown in dotted lines 1n Fig. 1 when 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. intermedlate hill 170 of the hill and ,valley member 18 until its end 32 engages with the elevated or raised valley 25. In doing this, however, the entire resilient driven member 10 will be instantly moved bodily with a positive sharp snap to the left of the vposition shown in Fig. 1. Upon again rotating the driving member 15, in either direction, the cam 14, whlch will then be'raised, will cause the end of the member 18 with which it coperates 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 the end of the spring 32 will instantly, with a quickand positive snap move up the inclined surface 170 of the A member 18 until the end 32 is caught in the valley 25. At the same time that this surface 32 is moving up the inclined hill 170 of the member 18, the entire resilient member 10 moves or snaps over instantly into its opposite osition, that shown in full lines in Fig. l. (Baontinued rotation of the driving member 15, in either direction, willV cause the driven member 10 to reciprocate with a quick and positive snap.

This mechanical movement may be used wherever it is desirable to employ such a device.

I have illustrated thisv mechanical movement as a switch mechanism in an electric light socket. lrVhen so employed upon the rotation of the driving member 15, which .in the form of the invention shown 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 thatthis driven member 10 reciprocates with' a quick snap. Y

In my improved electric light socket, the lip 20 ofthe screw shell 19 is preferably formed integral with the screw shell and bent up in l the position shown in Fig. 7. In assembling the two insulating members 2 and 3 this lip 20 extends up into the chamber 7 formed between the insulating members 2 and 3 and is one of the contacts as shown in Figs. 1 and l 4. A groove 171, Fig. 5, preferably formed partly in each of the in'sulatingmembers 2 and 3 permits 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 coperates with a locking screw 37, Fig. 4, which passes through the two insulating members v2 and 3 and holds them together. 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 inf sulating members 2 and 3 by reason of their coperating interlocking surfaces. The other binding post 38 is provided with a bent arm 39, Fig. 4, which extends through an opening in the screw shell 19l and becomes the center contact of the electric light socket.

' This binding post 38 is secured to,v the insulating member 3 in any suitable manner seated in the opening 41.- With the particular arrangement shown, the screw 40 is caused to engage with the binding post 38 before the two insulating members 2 and 3 are assembled. This binding post is also provided with a binding screw 42. Upon the rotation of the key or driving shaft 15 in either direction, the cam 13 or 14, as the case may be, will coperate with the intermediate or hill and valley member 18 and cause-the resilient driven member 10, which is formed of some conducting material, such as metal, to store u-p energy in the manner previously described. l/Yhen suiificient energy has been stored up in the spring or driven member 10, which will be about Vwhen the driven member reaches the position shown in dotted lines in Fig. 1, the kicker or accelerator 27 will crowdf the end 32 of the resilient driven member out of the valley 25 and lover its ledge 26. This will then cause the entire resilient driven member 10 to fly over with a positive snap from the position shown in Fig. 1, and at the same time, the consuming device, whatever it may be, will be thrown into circuit by the end 43 of the resilient member 10 contacting with the arm 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 member 10 are received -i'n the enlarged or,l

deeper recesses 8, 8, the shoulders 45, 45,

- lateral movement, the stops 45, 45, Fig. 3,

will prevent it.

The end of the driving `member 15 is supported between the insulating members 2 and 3 in any suitable manner, such as by `means of the bearing 46, Figs. 1 and 3.

The intermediate member 18 which I have for purposes of description termed a the cap and insulation together.

movable hill and valley member, is preferably formed from a. stamping and preferably in one integral piece as shown in Fig. 6a. It is, of course, t'o be understood, however, that it may be otherwise made.

I have found in practice that the ribs 29,

29 greatly strengthen the resilient driven.

member 10v and permit me to use a much cheaper and thinner metal than I would otherwise use if the strengthening ribs 29 were not employed. l They prevent the metal, under excessive use, losingits resiliency.

The insulating members 2 and 3 andthe 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 provided with 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. rllhis is a very cheap and serviceable manner of assembling and attaching 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 fiber insulation 56, Fig. 6.

The driving member may be formed in various ways. .Preferably I form it from a Vstamping 156, Fig. 12, having the. arms 57,

57 which are bent back upon themselves forming the cranks 13 and 14, Figs. 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. Other various ways of providing the driving member with cams may be employed such as for example, having the driving member 60 provided with two disks 61, 62 eccentrically mounted on the shaft or driving member, Fig. 14.

In some cases I may employ a resilient driven member 63, Fig. 17, without using thestrengthening ribs 29, 29, the resilient member shown in this figure being substantially the same as that illustrated in Fig. l1 with the vexception that these strengthening ribs are not employed. I have also found in practice that a very desirable refrom 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 provided with the offsets 65, 65 and with a hook 66 which its in an opening 67 in the arm 68 of the upper member 69 which is provided with an engaging surface 70 to coperate 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.

In many instances I have found that it is quite desirable to insulate the key or driving member 15 from the switch mechanism so that the metal key or a key formed of other vconducting 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 driving 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 any particular color scheme. Ihave 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 ywith valleys 75, 75, kickers or accelerators 76, 76,

' and with ledges 77, 77` in all respects subfurther rotating the driving member 15 in.

either direction in the same manner as previously described 1n 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 electriclight socket in whichvtwo push buttons are located adjacent to each other and on the same side of the socket. In Figs-19, 20 and 21, I have shown such a construction.V Here the' insulating member is formed also of two complementary parts 7 Sand 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 members 78 is provided with two openings 82, 82 to receive the push buttons 83 and 84. These buttons are provided with shoulders 85, 85 which coperate with the shoulders 86, 86 in the insulating' member 78 to limit the outward movement of the respective push buttons. In this form I may use any one of my driven members such for example as 10, which will be caused to reciprocate with a quick snap within the chamber 87 formed by the two openings 80, 81 in the members 78, 79. While I may use any form of inter mediate movable, or hill and valley member, I preferably use such a member formed out of insulating material such as 88 which is pivoted on the pin 89 and is connected,

` at 1ts respective ends, to the push buttons 83, 84 by the pins 90, 90. By pushing in the push button 83 the intermediate movable hill and valley member 88 will be caused to rock, in the manner previously described for the other intermediate members, and will store up the power in the driven resilient member 10, in the same manner as inthe 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 valley 133 and over the ledge 92 when the entire resilient member 10 will snap over with a quick snap and make a connection between the screw shell contact 93, Fig. 20, carried by the screw shell 94 and the contact 95 of the binding post 96 carrying the binding screw 97. To disconnect the consuming device, it is merely necessary'to depress the push button 84 which will have then been elevated. Alternate pressure upon the push buttons, which are for the moment extended, will .cause the spring member 10 to alternately snap into and out of contact with the contacts 93 and 95. In this form the binding post 98 is provided with an arm 99 which is the center contact for the consuming device. -This binding post 98 is provided with a binding screw 199 and is held to the insulating member 78 by means of the locking screw 100. The binding post 96 is secured to the insulating member 79 by the locking screw 101 which is passed through the insulating members in the opposite direction from the locking screw 100. In this manner the insulating members are secured together at the same time that these screws secure the binding post to the insulating members. The same operation will also secure the screw shell 94 to the insulating members 78, 79 by holding the dovetail surfaces 175 on the insulating members in contact with the dovetail 176 on the screw shell 94.

My invention also comprises an electric light socket actuated by a push-through button extending on either sidev of the socket.

i 108 of the accelerator or kicker 109. This accelerator or kicker is mounted upon the intermediate rocking or hill and valley member 110 pivoted by the pins 111, 111. The engagement of the edges of the accelerator 108 with the openings 107, 107 in the enlarged portion 105 of the driving member 102 forms a pivoting connection between the rocking intermediate member 110 and the laterally reciprocating driving member 102. Whichever way the driving member 102 is reciprocated the intermediate member 110 is therefore caused to rock upon the pins 111, 111. I n this form of my invention by pressing for example upon the push button 104 the driving member 102 is caused to move to the left from the position shown in Fig. 22, this motion being transmitted to the rockino coperating with the accelerator 108, and power is stored up within the resilient driven member 10 until such time as the accelerator or kicker 108 crowds the end 32 of the spring or driven member 10 out of the valley 113- over the ledge 112 when this end 32 will be caused to move down the hill 177 of the plate or intermediate member 110 until the end 32 snaps into the similar valley 113 in the other end of the intermediate or hill and valley member 110. In doing this, however, the entire resilient member 10 is caused to move with a quick and positive snap through the opening 10G in the driving member 102 and make or break the electrical connections not shown) in this form of the electric light socket. The binding post 115 is held to the insulating portion 116 by the screw 117. The two insulating portions 116, 118 are heldtogether by means of the locking screw 119 which coperates with the binding post 120 on which is mounted the binding screw 121.

Another form of my invention is a mechanical movement in which the intermediate or rocking .hill and valley member is carried by separate members coperating with the driving member. This form. of my inventionis illustrated in Figs. 24 to 29 inclusive. My invention also includes the electric light socket therein disclosed. The driving member 122 in this 'orm of my invention is provided with cranks 123, 124

upon which are mounted links 125, 125, one link being mounted upon each crank. These links `are preferably formed out of stamped metal, and, as sho-wn in Fig. 27, comprise a for the reception the case may be,

head 120 having a slot 127 of the cranks 123 or-124, as

vmember 110 through the walls of the slot 107 and are further provided with legs 129, 129 having bent in portions 130, 130, Fig. 27.

Upon the legs 129 I mount my intermediateV or movable hill and valley member 131 which is preferably formed out of a single stamping its `ends being cut at 132, 132 to form the kickers or accelerators 133, 133, the valleys 150, 150 and the arms 134, 134. By way of example I have shown the kickers or accelerators bent up in one direction, and the arms 134 in the opposite direction, Fig. 29. These arms 134, 134 coperate with the bent in portions 130 of the links, leaving the bent up portions or accelerators 133 free to cooperate with the end 32 of the resilient driven member 10. The two cooperating insulating members 135, 13G are provided with guide grooves 137, 137 within which slide the links 125, 125. By rotating the driving member 122 in either direction, the cranks 123, 124 will reciprocate the links 125,'within their grooves 137, carrying with them the intermediate or movable hill and valley mem ber 131. If the driving member 122 is rotated in either direction from the position shown in Fig. 2,4, the elevated link 125 will cause the end of the plate 131 with which it coperates, to move down and cause the two ends of the resilient driven member 10 to approach each other until such time as the accelerator or kicker 133 will crowd or force the end 32 out of the valley 150 and over the ledge 138 of the member 131 when the spring or resilient driven member will instantly snap over with a quickand positive snap from the position shown in Fig. 24 to the left until the entire driven resilient member has been moved to the left and its end 32 has been received in the other valle)T 15() of the intermediate member 131. This movement is instantaneous once the end 32 is released from the particular valley 150 with which it happens to 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 snap back into the position shown in Fig. 24. y

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 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 quick and positive snap without arcing so that both a quick make and a quick break will be made upon the rotation of the driving melnber 122 in either direction.l The screw shell 140 is cut away at 145 so that the center contact 146 which is preferably an arm of the binding plate 147, may be inserted. This binding plate 147 is secured to the insulating member 135 by means of the screw 148. The binding screw 149 is carried by the binding plate 147. The binding post 144, carrying the binding screw 151, is secured to the insulating member 13G by means of the locking screw 180 which serves at the same time to secure the two insulating members 135, 136 together.

It is, of course, to be understood that while I preferably use one kicker or accelerator with each groove or valley I may in all forms of my invention omit such accelerators or use only one even if two grooves or valleys are used.
