"To all whom it may concern:

Be it known that we, THEODOEE Jr., and JOHN T. FAGAN, citizens of rthe United States,t residing at Cleveland, county of Cuyahoga, State of Ohio, have invented certain new and useful Improvements` in FilamentSupport-Wire-InsertingMachines, of which the following is a specication'.

Our invention relates to machines used in the manufacture of incandescent lamps and,- more particularly, to machines forV insertingl hooked wiresin glass rods so as to produce the filament supports commonly used in con- `nection with metallic filament incandescent lamps. The object of ourrinvention is to produce a machine 'of the aforesaid character by means of which thenecessary `oper ations may be quickly and accurately per formed.,

According to our invention, means are provided Ifor holdinga glass rod which commonly has buttons formed lthereon into which the support Wires are to be inserted, so that it may be turned by the operator to receive as many support Wires as desired. The machine is provided With Wire holding `means and with a. wire feedingmeans comprising a guide having a located so that the Wire may e firmly seized and inserted into'the glass button upon the proper ,action by the operator. Moreover,` means are provided for fusing that portion of the button which is to receive a wire, and

i a cooling means is rovided which is brought into action-imme iately after the insertion of the Wire'to cause" the rapid solidification .of the glass around the end of the saidiwire.

Thefglass fusing means comprises means for directing a flame against a portion of the edge of the button on the glass rod-andthe said means is angularly disposed relative to the plane of the said button so that there is no danger of injurin Wires previously inserted in the button.

ur machine comprises also a wire cutting and hookformin inearls which are brought into 'operation a ter the' withdrawal "of theffwire gripping means.

This means practically simultaneouslv Vcuts ofi the wire and yforms the hook "at y end l' thereof. They cutting -means fisk made 'ad`` justable so that sharp edges may be readily substituted for those dulled by thefwire.

Thisr is of decided advantage,because the Vthin tungsten. or other wire ofthe resilient W. FRECII,

ipping means.I

supports, for the insertion of ivhich our machine is particularlyadapted, very quickly dulls the ordinary cutter. To this end, the cutters are disk-shaped'and have serrated edges. This structure has? the additional advantage that thc wire is alined accurately by the 'cutterteeth at each cutting operation. y .The parts of our machine are adjustable so-that various sizes of glass rods and Wire may be handled thereby. `Moreover,

the support for the glass rod is such that the support wires may be inserted at any 4Patented Mar. 27, i917.

desired angle therewith. The parts 'of the i machine are so arranged and connected that theyare actuated by manipulating a han dle or similar device to automaticallyk per- `form the afforestated operations lin proper se quence. Various other advantages ofj our machine Willappear from the more detailed description `,which follows. y

Our inventionlwill be more clearly understood by referring to theaccompanying drawing in which Figure 1 is a front elevation of the machine; Fig. 2 is a plan Fig.`

'and '9 are detail elevations showing the wire inserting mechanism in advanced and retracted position respectively.

Referring to Figs. 1 andQ, itwvill be seen may 'be secured in any 'suitable manner to 4the top vof a Work bench. At one endf, as

4that the machine comprises a base 1() which i tally extending rod 15 and. has angularly disposed bearing surfaces 1 6 at its end.` The y other member 17 isslidably fastened to the A rear 'of the` member' 14s,v being heldv thereto by the bolt and nut 18 passing through slot 19 in*said`memberg17. The member 17,'is provided at the end\thereof with hooks'20 which are adapted 'to conform to the surface of thev glass rod 11 and to hold the same firmly against the surfaces 16, being acted upon by a spring 21 which extends from pin 22 therein to the pin 23 extending from rod 15. :By means of the vertical rod 24 pivotally mounted .in theholding member 13 and carrying a lug 25 which extends through a slot in member 17, and the handle 26, the said member 17 may be advanced to allow the insertion or removal of the glass rod 11. To allow the. position of the holding clamp to be readily adjusted, the rod 15 is adjustably held in the sleeve 27 and the said sleeve is pivotally supported by standard 28 carrying sleeve 29 having ears 30 through which extend the adjusting screws 31. The standard 28 is`mounted to allow adjustment in a sleeve 32 carrying clamps 33. To allow the accurate positioning of glass rods in the clamping device, a stop 34 may be adjustably mounted on the stationary member '14 of the spring clamp, and in inserting the glass rod into the clamp the top surface of the button 12 should be -forced against the said stop. In order that the operatorvmay know accurately how far l to turn the glass rod after. the insertion of a support, an indicating pointer. 35 adjustably held by a standard 36 may be provided. At the other end of the base 10 is provided a. holder for the wire holding means or reel 37 carrying the support wire 38. The said holder consists of a. horizontally extending rod 39 carrying the stationary bearing 40 and 'the lmovable bearing 41 which is acted upon by spring 42 adjustably held by bushing 43. The Wire 38 extends from the reel i 37 through the .channel 44 in a reciprocating guide'45 which slides in the uppermost slot 46 in a carrier 47 which is supported by the hollow vertical frame member 48. As shown in Figs. 5, 8 and 9, the. forward end of the guide is transversely channeled at 49 to receive the end of the gripper which is pivoted thereto at' 51. The said gripper is o'fl'set somewhat back of its forward end at 52 (see Fig. 2) and has an oblique shoulder 53 in line with its gripping end. Arranged i and adapted to engage the said shoulderis the end of an oblique arm` 54 which is parallelto the shoulder 53. The arm 54 is attached by a vertical arm 55 to the bar 56 which is reciprocatably mounted `in a slot '57 in the carrier 47. A spring58 normally holds the gripper against the wire in the channel. The bar 56 extends through the carrier somewhat beyond the rear end of bar 45 and is attached to a vertically extendingl member 59. This member has an upper shoulder 59 in line with bar 45. Also attached to the member 59 is the horizontally extending bar 60 which is slidably mounted in the lowermost slot 61,y in/ the carrier 47, and extends to about the middle of the hollow frame support 48. Pivotally attached to the forward end-*thereof slotted to receive the same-is the crank .62 attached to the `operating shaft 63 whichis providedwith handle 64.v i A spring 65 extends from the lower end-of themember 59 to anv adating shaft' is turned to the left by means of handle 64 the member 59 is moved forward with its connected parts against the action of springl 65. The forward'reciprocation of bar 56 causes the end of arm 54 to bear againstthe shoulder 53 thus forcingy the ygripper 50 down upon the wire. The continuation of the reciprocation causes the shoulder 59 to" engage the end of the upper bar'45 and the wire is advanced with the parts in the position shown in Fi 8 to insert the end ythereofinto the glass button 12. Just prior to the insertion of the wires, as hereinafter described, a gas blow flame is played upon the part of the button which is to recelve the support wire and immediately following the insertion, as hereinafter described, a cooling vair blast is' played upon the said button part to solidify the same. Upon the release of pressure upon the Ihandle. 64 theaction 0f the spring 65 causes the bar 56' to be retracted thus releasing the pressure upon the gripper 50 and further causes the arm 55 to engage the shoulder 45 on bar 45 and to carry that bar l with the gripper50 back to its original position. At the same time the operating handle -wire is directed from the air and gas burner 67. This is of the character disclosed in Fagan Patent No. 1,031,842, issued JulyI 9, 1912, and comprises the trough-shaped head 68 covered by gauze 69 and communicating with a gas supply pipe'70. The air blow pipe 71 is arranged to direct a blast of air longitudinally of the trough and to direct a pointed blue gas flame against the button- 12. The blow pipe is connected as by the goose neck 72 to the air supply pi e 73. As shown in Fig. 3', the gas pipe 7)() `is connected to a passage 74 in a member 75 and said passage communicates with a valve chamber 76, the assage 77 of which is controlled by the ad" 79 communicates with the passage 77 and serves as a support for the-burner as a whole, being, as shown in Figs. 1 and 2, held by the clamp 80 which is held between grooved clamping members 81 bythe screw clamp Justable valve 78. A pipe` y. 82. connection the universal adjustment of the burner; the air pipe 73 and the inlet passage SI5-connecting thereto being controlled by adjustable valve 85.* The I pipe 86 communicating with the* inlet passage 84 is connected to a rubber Vor other.`

exible supply tube 87. Means are rovlded for checking the air supply to the b ow pipe l 71 after the glass button hasI been softened suiciently to allow the insertion of the support wire.y As shown, this means comprises a clamp 88,` 'between the short stationary part 89,and the-longer movable part 90 o'f which, the flexible tube 87 asses. The part 90 is pivoted at 91 to the rame member 48` a'nd Works between the guide pins 92. Projecting from the same face thereof which engages the tube 87 and at the opposite end thereof is a lu l93^which bears against the cam 94 upon te operating shaft 63. The said cam has an indentation 95 therein which corres onds to the position at which the blow ame is to be directed against the button 12. When this reaches the lug v93 the pressure is released upon the tube 87. At all other positions of' the Voperating handle the -tube 87 is firmly compressed between i 95" on shaft 63with the top 102 which, as shown in with an air reservoir 103. Tothe opposite i the members of the clamp and the air blast is shut off. The movement of the operating hanidle to the left is limited by the engagement of a pin `projecting from collar of the clamp-` member 90. y

As stated heretofore, means are provided,4

whereby a blast of cooling air is directed against that portion of the button 12 which receivesthe support Wire immediately upon the insertion of the said wire. The cooling blast is directed by means of the blow pipe 96 whichV is connected to the union 97 secured to the standard 48. As shown in Fig.t5, the

endof the cylinder 100 an outlet pipe 104 communicates. -This pipev connects with a pressure accumulating device not shown, the purpose of whichis to permit the blast to be quicklyturned on. The inlet to the pipe 104 yis controlled by valve 105 mounted upon the same stem 106 as the valve 99. The said valves are'so disposed that when one is in open position the other is closed. The stem 106 extends somewhat `beyond the.` end of to be engaged at the proper'time by the'end of" a pin 107 -adjustably mounted on an offset arm 108 extending from the member 59.

The arrangement is such that as the member 59 completes its forward movement and as Fig. 1, communicates extending from the head 47.

the rest of the wire." This hook former cutter-is illustrated. in detail in Figs.`6 and 7. 'It comprises upper and lower members mounted on shafts 109 and 110 respectively. Y The upper member comprises the cutter 111 and the male die member 112. The cutter 111 is :preferably disk-shaped, has a serrated edge and is rotatably mountedon an'arm 113' 'l extending from the journal 114 mounted on the shaft 109. The die member 112 is removably held to the iarm 113 by the clamp 115. The lower member of the device consists-.ofthe arm y116 journaled 'loosely on shaft 110, the female member 1,17 of the die.. being clamped removably thereto and the serrated Vcutting disk 117 vbeing mounted thereon. so that it may be adjusted by rotation thereof. One advantage of the rotatably-mounted serrated-edged disk cutters is that when one pair of edges becomes dull, a sharp pair may be brought into operation. Moreover, the teethjof the cutters act t hold 'the wire in proper position whenl cut.. `One of the shafts, as shown, shaft 109, has attachedthereto a means for turning the same. The journals of the yarms 113 and 116 are providedwith intermeshing teeth 118 so th'at the rotation of the shaft 109 4in one direction causes the cutter and die members to ap- Y proach each other and in the other direction to separate a proper distance to allow the passage of the gripper in the next operation of the machine. The vshaft 109 extends through and is journaled near one end in a supporting bracket'119, which is slidably` mounted `on an arm 120 extending from the frame 48, being held in any desired position by the setscrew 121. `The other, end of the shaft is journaled in stationary bracket 122 i Anadjusting screw-threadedpin l123 extends throu h correspondingly screw-threaded holes 1n the stationary bracket, and in the lug-124 extending from the movable bracket 119. By loosening the set screw 121 and turning'the screw pin 123 in the proper direction, the position of the cutter and die may be accurately adjusted. The shaft 109. is square in section at the end thereof remote from the cutter and'die andpasses through a squarevv hole in a `crank125 which vis'pivotally attached to a vertically extending pin '126.

The latter extends loosely'through a hole in a guide bracket127 which extends from the journal of the operating shaft 63. A lug 128 projecting from a sleeve fast to the shaft 63 is adapted to engage' the end off the `3.0 of the machine at the one end and to an.

v apertured arm 130 extending from the outer vend-of crank 125 serves to return the'shaft 109 and connected karts to their original-positions as the han e 65 is turned to the right. The spring'131 acting against the collar 132 on lshaft 109 serves to hold the same yieldingly against lateral displacement relative to bracket 119.v

It. will be apparent from the above de-A 20scription that the operations of heating the button, inserting'the end of the wire into the button, cooling the button and withdrawingthe wire gripper are successively performed during the movement of the op- 26 erating lever from vertical position to the left until the stop pin J95 engages the top of clam 90 and then back to vertical position. the ri ht then causes the lu'g'128 to engage 80 end of rod 126 which by'4 turning shaft 109 causesthe cutter and hook forming ymembers =to come together. This results in the severyance ofthe inserted support wire and the formation of a hook at the end thereof. Upon subsequent movement of the operating lever to the left the cutter and die members are automatically separated through the action of spring 129. The operator may then turn the lass rod until it is in position for.

40 the insertion of another support wire. Upon the insertion of the proper number of support wires in the button of one rod, the rod lmay be readily removed'by a lateral 'movement.y thereof after .release of the 4spring clam 13.
