- AppIcation ledFebruary 9,191.4. Serial No. 817,472.

To all whom. it may concern.:

Be it known that I, RALPH mouth and State of vNew Jersey, have invented new and useful Means for Operating Switch Mechanisms, of whichthe following is a specification.

My invention relates to means for operating switch mechanisms and vparticularly when suoli mechanisms are placed in sockets or other receptacles especially when adapted for carrying electric light lamps or attachment plugs.

In t-lie case of sockets or other ieceptacles it is highly desirable todo away with the unsightliness caused by protruding actua'- tors, such as keys, chains and push-buttons. These actuators are a distinct drawback asa rotary lamp, however, hasy many'objections and the main object ofmy invention is to do away withsuch protruding actuators and also to eliminate the rotation ofthe sup porting member for zthe lamp,` attachment plug or other device. v

My invention consists mainly in providing means at the end'of the receptac e moving longitudinally to actuate the switch mecha# nism and this longitudinal movement is in ai direction substantially parallel to the. wall of the socket or other receptacle no matter in what direction the lamp or other device may point, that is, whetheriit'is vferticalor horizontal or atan angle with the horizontal. A feature of my invention consists in pro. viding a quick make and quick'break brid-g ing member moving longitudinally.-

Another feature ofl my invention is that in the case of lamps I` avoid the necessity of ya. protracted grasp ofthe lamp with the'convsequent likelihood of burning the hand as is the case with a rotary lamp for operating the` switch.

Another feature of my invention is that I Specification of Letters Patent.A

avoid all `arcin-g which will be present in turned .in the reverse direction, this likelithe case of a rotary lamp whenptlie latter is hood ofarcing-being present especially in high wattage lamps.

Another' feature is that 'an attachment plug can be placed in the socket and operated by. a pull on a cord attached to the plug where the plug is not within reach orwhere a quick method of'breaking'the-currentisV desired.

A further advantageis that" there is-fno likelihood of'breaking the'lainp as might be the case if a rotary lamp were used-for the reason thatthereare now many standard keyless sockets now in' use and the operator wouldy try to rotate the lampnot knowing whether the device were operable by rotation ofthe lamp or `not `and if itwere not the lamp would undoubtedly break in the hand of the user;

A further Ifeature of my invention is thatv in case the lamp or other device vis out of con# 'i venient reach a chain or' other member attached tov the supporting member may be used to move the supporting member and this could not be done with a. rotary lamp.

In one embodiment of my invention whichl I. disclose herein,fthis being for some vpurl.poses the preferred form, I provide a socket which carries switchmechanism and mov ably mounted on the socket is a lamp support carrying alamp, longitudinal movement of the lampsupport acting to make andvhreak a circuit through theswitch to' light they lamp or extinguish the light and a.

special feature of the preferred'forrn is that movement of the lamp to operate the switch is always toward the socket, that is, pushing the unlighted ylamp will light it'and'pushing the lighted lamp will extinguish thelight.

Other features of my invention will he pointed routbelow.

Having reference.particularly vto Figs.`1 to `4 inclusive, 1 represents. a porcelain block formed with a central vertical hole 2 which at its lower end con-nects with a recess' Vpro-.-

vided at thelower end of block 1. v"' ZVithin the hole 2 is a. bushing 4 provided at'itsf` lower end with .a flange or head andh'aving its upper end threaded to receiverupon'f ita nut-5by means of which the-bus yngiss'ecurely held within-the block w1?.,"if 1 totatably'.

mounted upon the lower end offbushing 4is a movable contact 6, Fig.14,l provided with downwardly projectingratchet teeth-,7 vto cooperate' with upwardly projecting ratchet teeth l8 provided on a disk 9 mounted upon a screw stem 10.v Disk 9 is made upon 'its inner" periphery with alug 11` occupying'a spiralI groove 12provided on the eXteriorjof-stem' 10, and is yieldingly held against'movable contact member 6 by. a spring 13,;f`Stem 10 near its lower end is provided :witha head providedwith -two diametricallyl opposite wings 19 and 20 which coperate witha sta-l ff nuancer..

'tionary contact member' 21 fastened to the porcelain lblock 1 and adapted to be con- 'nected through binding -post 24 with one of the line wires' 25 of the circuit. The other line wire 26 of the circuit is connected with a binding post 27 which is electrically connected with a spring contact linger 22 mounted on porcelain block 1 and engaging a. metal contactmernber 23 fastened by means of one of the bolts 17 to the movable lporcelain block 16. The bolt 17 which holds contact member" 23 in place electrically connects the contact'member'with the threaded shell 18. kWhen the circuit is closed through my improved switch device it extends from one linewireto the stationary contact 21 thence through the movable contact member 6 to stem. 10 which leads to the center contact 15.' From the center contact 15 the circuit passes through the lamp or other instrument connected with the shell 18, back to said shell and thence through bolt17 to contact member 23 from whence it passes 'through Contact nger 22 which isfcoim'ected -with .the other line wire. By referring to Fig. 1 it 'will be yseenqthat'the contact-member 6 is electrically connected with stem'lO noty only through the bushing 4 but also` through the toothed washer 9 which amply provides for .the passage of the current. The exterior of the stem 10 is made with a longitudinal key-wayjl- 28 .into which projects a lug 2,9.' from sleeve 4 which serves by its f engagement with'said key-way tolock said stemaga-in'st rotating within said sleeve; the

The wingsi19 and20 ofkrrfnovable contact-member 6 also y copera'te with a pair of spring jaws 30 and lsecured'to block 1' inthe path of said wings andlocated 'ninety degrees away from the stationary contact 21. These 'stirring jawsj30'and 31 form no part of the circuit.. `When the screw shell 18, block 16 and stem 10- areushovedfupwardly the spiral groove 12 acts uponlug 11 to rotate disk 9 whose teeth' 'engaging with the'teeth on contact member 6 act tomove sai-d contact member .with said stem: The limit' of inward movement of screw shell 18, block 16'and` stem 1() isartent of ninetyfdegrees.

Inthe form of my invention shown in Figs. 6 to 13 inclusive the stationary porcelain block is made up of twocounterpart pieces of porcelain 1, Fig. 13, and is provided with a contact finger 22 like the contact 22 of Fig. 1, which coperates with'a s )rin contact iin er 23 like the s rino' conl g g p :a

tact finger 23 of Fig. 1. The two pieces of porcelain 1b which make up thestationary porcelain block vare provided upon their inner faces with registering recesses 40- within which the springs 39 are pocketed. Also in 'this form of my invention the movable porcelain block 16 has'V the screw shell 18 fastened to it by means of`bolts 17v and the center contact 15 is screwed onto the lower end of a post 10b so'as to fasten said post totsaid block as in Fig. 1. The two pieces of porcelain 1b are made upon their .inner faces with registering recesses 53- which pocket and support a metal contact ring 51 that is' provided with two `downwardly extendingy HeXible contact fingers 55 coperating with an= enlargement 6 provided on the post 10". The contact ring 54' is made with an extension 56 that is fastened to the porcelain block 1P by means of a bolt 57 which serves also to hold the two'parts of the porcelain block together and has a binding post for a line wire 58. The other line wire 59 is connected with another binding post boltv 60 whichfastens the contact' quick make and quick break between the enlargement 6 and contact fingers 55 by an endwise or longitudinalmovenient of the post 10b and screw shell 18.

In the form of mypinvention shown in Figs. 15 to 19 inclusive 1 indicates the stationary porcelain block, 16b the movable porcelain block, 18 the screw shell, 34 the lining of insulating material inclosing said parts, 35 the metal shell surrounding the lining 34, 36 the cap of

shell

35 and 25 and 26 the line wires. The stationary prcelain block 1 is made with a recess 61 within which is arranged a ratchet wheel 62 provided uponone face with a series of studs -63 coperating with a spring pawl '64 fastened by a screw 65 to the movable por celain block 16". The porcelain block 16b is said ratchet wheel.

moved toward and from the stationary porcelain block 1 to open and close the circuit as before and as the spring pawl 64 moves with it it acts to rotate ratchet wheel 62 step by step. The ratchet wheel62 is made with four laterally projecting lugs 66 adapted by the rotation of said wheel to be brought successively into engagement with a stationary contact 67 fastened by a screw 68 to the stationary porcelain block 1. The contact 67 is made with a downwardly extending finger 69 whichis in permanent engagement with a Contact finger 70 riveted or otherwise secured to the screw shell 18. A spring detent 71 bears against ratchet wheel 62 and coperates with the studs 63 to prevent reverse movement of said ratchet wheel on the .down strokes of pawl 64. This detent 71 is fastened to the stationary porcelain block 1c by means of a screw 72 which servesalso as a binding post with which the line wire 25 is connected.' Detent 71 not only'prevents reverse movement of ratchet wheel 62 but` also serves as an electric connection between binding post screw 72 and The studs 63 are provided and arranged so that each upward 4movement of pawl 61 rotates ratchet wheel 62 4a distance equal `to the angular distance between two of the studs so that every other up stroke of pawl 64 shifts one of the lugs 66 into engagement with contact 67 while the alternate up strokes of the pawl 64 disconnect ratchet wheel 62 and contact 67. The center contact 15 is made with a threaded hole to receive the lower threaded extremity of a post 10 provided at its upper Aend with a. head 73 beneath which is .ar-

ranged a spring 74, said .spring serving to normally hold the block 16b against the porcelain block 1.. On its under side the porcelain block 1c is made with a recess7 5 within which is 4arranged a contact 76 that is fastened to the porcelain block 1 by means of a screw 77. The screw 77 serves` as a `binding'postto which theother line wire 26 is connected, and the contact 75 is in perving plug to the heater or other instrument.

When the circuit through the heater. or other instrument connected with the wires 80 and 81 `is open and it is desired to close the same the operator may accomplish this merely by pulling upon said wires and then releasing them. The pull upon the 4wires draws the connecting plug 79, screw shell 18, porcelain block 16b and post 10C outwardly against the pressure of spring 74 which latter returns said parts to their innermost positions whenthe pull upon wires 80 and 81 is relaxed. Pawl 64 moves with the porcelain block 16b and through its engagement with the ratchet wheel 62 turns the latter one step carrying one of the lugs 66 into engagement with the contact 67 thereby closing the circuit through the heater or other instrument. When it is desired to open the circuit through the heater or other instrument the operator will again pull upon the wires 80 and 81 which results in another in and out movement of the connecting plug 79 and parts connected therewith. lV-hen block 16" is thus moved with the connecting plug' 79 its pawl 64 again moves ratchet wheel 62 one step carrying the lug 66 resting against contact 67 away from and out of engagement with the latter thus opening the-circuit through the heater or other instrument. It will thus be seen that with this form ofmy invention an important advantage residesgin 'the construction which permits -ofits being operated from a distant point to open and close the circuit through thevmedium of the wires 80 and 81.

lVhen my improved switch device is used to hold a lamp and is to be placed in an elel vated position where it cannot be conveniently reached I may provide an attachment 911 shown in Fig. 20 consisting of an annular flexible strap 95a whose ends are fastened together by means of a screw 82 so that the strap is confined between two

shoulders

83 and 84 that are provided upon the exterior of shell 35. This strap 95a is made with a depending arm 85 extending downwardly alongside of the lamp bulb 32l and at the lower end of this arm there is provided aI bell-shaped cord guiding aperture 86. One end of a cord 87 is tied around the shank of4 the bulb 32 and said cord eX- tends therefrom downwardly throughthe guide 86 with its lower end arranged in a convenientposition. This attachment is applicable to the switch device shown in Fig. 15. i

When my improved switch device is used to hold aA lamp and is arranged in a more or less elevated position with the lamp uppermost as shown in Fig. 22 l prefer to provide the lamp with the attachment shown in Figs. 21 and 22. This attachment comprises two metal strips one of which 88 is bent near its middle to tend half way around the shank of the bulb 32 with the ends 90 of said part bent upwardly and outwardly and having their eX- tremities hooked as at 91. The other part of this attachment comprises a metal strip 92 bent-to form a loop to extend around the form a loop 89 adapted to eX other half of the bulb and having its extremities fastened to the part 88 by means of two screws 93. This form of attachment may be used with any one of the switch devices herein shown and by grasping either or both of the arms 90 the operator may conveniently move the lamp to operate the switch device.

The stationary porcelain block 1c ofFig. 15 is made at 'its lower end with two diametrically opposite lugs 91 occupying two notches 95 provided in the movable porcelain block 16. These lugs and sockets connect the two porcelain blocks so that they can be moved relatively toward and from each other but are held against relative rotative movement.

In FiO'. 23 I have shown my invention embodied in a switch connector or union adapted to be used for instance, to connect an ordinarylalnp or cord plug with an ordinary socket. This form of my invention comprises a screw shell 18 secured to a movable porcelain block 16 carrying a spring contact -the threaded end of the shank of another center contact 97. The stem 10b is, like the stem 10b of Fig. 6, made with an enlargement 38 cooperating with a pair ofk springs '39 pocketed within a stationary porcelain body 97a. At its lower,- end the body 97a is made with a skirt 98 inclosing screw shell 18, and at its upper end with a plug 99 upon the outsidek of which isarranged a second screw shell 100. This screw shell 100 is held in place on plug 99 by lugs 101 which are bent inwardly into recesses 102, and carries the contact 22b which may be integral therewith or soldered thereto. The porcelain body 97a may be made in two counterpart sections fastened together by bolts 103. The shell 100 and center contact 97 constitute engaging means provided upon this form to attach to the terminals in the mouth of an ordinary socket.

anism with longitudinally moving means for operating the same and engaging means to attach to the terminals in the mouth ot another socket as I intend to make those features the subject of another application or applications.
