To all whom it may concern: i

Be it known that I, EDWRD SIMON, a l citizen of the United States, residing atl Shelby, ichland county, State ol? Ohiof have invented certain neuv and uset'ul lmi provementskin Machines :tor 'Forming Incandescent-Lamp,Mcunts, or' which the following is a specification. i

The invention relates toV machines formanufacturing incandescent lamps and has for its object the provision of a machine 1 whereby the production of the mountsj i support the lead and anchor wires is greatly facilitated.

` The invention can be best explained connection with the accompanying drawings, in Which- Figure 1 is an elevation of a machine embodying my invention; Fig. 2 is an enlarged elevation partly in section ot a portion of the apparatus; Fig. 3 is a top plan vie'ivot the machine With certain parts ol' the para-tus removedfor' the salie of clearness'; Fig. et is an enlarged view of the portions which are immediately concerned in the formation of the mount; Fig. 5 is a detail showing a means for operating the appan rat-us shown in Fig'. 4', and ltig. 6 is a plan view of theclamps for holdingthe mount tube.

-Referring to the drawings, A indicates a base upon which is mounted a post B, which These arms are' rigidly secured to the hub an'apparatus lfor forming a mount tube vas'Will be, hereinafter further described. Mounted in the base and separated by a distance equal to that bet-Ween adjacent arms are two rollers 7c and 7.3 which are. adapted to actuate the mount forming apparatus upon successive arms and which may be driven in any suitable manner. Also mountf Located adjacentto the rollers if: and It" and therefore adapted to operate upon the devices carried therefore a description of one will bea description of each, 'Referring especially to Fig. in the hub it upon the arm l is rotatably mounted the hollenv shalt l, which at its lovfer end has secured to it a `wheel 2 adapted to enero with the roller ic., The shaft 1 is shot gain'st the upper end ot the hub'z. se that end vfise movementof the shaft is prevented. 'lilierelthe shaft l emerges lromv the hub 7i, the arm 3 extends laterally and then vertically. To the arm 3 are rpivotcd the clamps l Vi which may be geared together as shown in order that equal movement of the two may be secured. rl`he clamps are normally held closed by means oi a spring but may be `opened by pressure upon the finger pieces G and 7. The centers oli the clamp lie in the axial line of the hollenv in the shaft.; 1. Slidably mounten in the hollow of the shaft 1 is a plunger rod t3 which extends below the lower end oi the sha-tt .1. At the upper end of the plunger rod il' is provided a recess il for the reception of anchor Wires.

Above the shaft l a cross head 10 is con- ,nected with the plunger rod 8. Thisconnection may conveniently consist of a key 24 having a driving fit in the cross head and extending into a slot .25 in the plunger rod as shown clearly in Fig. d. lo this cross head are pivoted the

links

11 and 19. `which are also pivoted to the sealing

clamps

13 and 14. which in turn are pivoted to an'arni 15 projecting laterally from the arm 3. At their upper ends, the

clamps

13 and 14 are provided with faces for forming the mount. Supported by the arm 15 .and in line with vtheplungcr 8 and the clamp grip is a die block 16 above'which the mount is formed. The die block is made tapering at the top so that aeridge is formed upon which the mount tube or flare may rest. The apex of the ridge is of less width than the diameter of heauouut tube so that access to the tubeI at thc bottom may be obtained and the heat which impinges upon the die block may be deflected upward into the interior of the mount tube, lt is further to be observed that thc ridge extends parallel to the mount forming faces. ,If the ridge extended at right angles to the mount torminglaces, the mount tube upon becoming hot might sink down upon the sides of the ridge and the coming together of the faces to loriu the p mount would teiidvto cause it to sink still leave none hanging down about the sides..

The'die block 16 `has a tapering axially f extending hole 1T in line with the recess 9 Aand withothe mount tube, which is adapted to receive the end of an anchor wire placed in the recess 9 and guide the. said wire into its proper position. The die .block is further provided at its` top with

recesses

18 and 19 adapted to receive the ends of lead wires placed within a mount tube held in the

clamps

4 and 5 so that the said lead wires" are held in definite relative positions and their ends may project beyond' the end of the mount.

The apparatus thus described being mounted upon each of the arms, may be rotated by means of the roller f; which engages with the Wheel l2. The support and means for actuating a roller 7e will now be described and a similar apparatus is employed to support and act-nate the roller 71:'. The roller le is fixed to a shaft 20 joiirnaled in the base and secured against axial movement by

collars

21 and 23 ixed'to the shaft 20. To the lower end of the shaft 20 is fixed ra driving pulley 22.

The means D for securing the arms in given position may consist of a hollow post 27- in which is mounted a spring pressed,

plunger 28 adapted to engage with a pin 29 extendingofrom each of the hubs at thev outer extremities of the arms a' b 'c d. A rod 30 secured to the plunger 28 and extending downwardly through the base A provides a means whereby the plunger may be moved downwardly against its spring and out of engagement with the pin when the arms may be advanced as desired. The rod 30 may be connected by any suitable means as a cord 31 with a pedal pivoted to the floor so that its operation may be effected by the foot of the operator.

To cause the plunger 8V to be moved upwardly and thereby to bring the mount. forming faces of the

clamps

13 and 14 to gether about the base of the mount tube and also to feed the anchor wire upwardly into position, a vertical rod is slidably mounted in the base A and is adapted to engage at its upper end with the lower end of the plunger 8 and at its lower end 4is adapted to be engaged. with one end of the lever 3st pivoted to the base 'and operated by 4a handle 35. i

1n order that the mount forming faces of the clamps A13 and 11 may be properly spaced the clamps is provided, which means is preferably carried upon the clamps and may consist in screws 36 mounted upon the forming faces. y

Having described the variousl parts of a machine embodying my invention, I will. now outline its operation.

An operator seated between the, arms L and b when the machine is in the position chine illustrated, provision isma'de for but one anchor wire, but it Will be obvious that any desired number may be employed. In the position shown, the pin 29 upon the hub z, upon the arm d is in engagement with the lplunger 28 and the rollers c and 7c bear upon the wheels 2 upon the arms c andai, so that the shafts 1 upon those arms andltlie apparatus carried thereby are rotated'. A downward pull upon the rod 30 by means of the pedal as before described operates to release the pin 29 fromV the plunger 28 when the arms may be moved into the next osi tion, that is, where the plunger 28 is in engagement with the pin 29 upon the arm c. The rollers 7c and :l will then be .in engagement with the wheels 2 carried by the arms b and c. The flame proceeding from the.

heating device E which is now adjacent to the arm b will play upon the lower portion of the mount tube, m, that tubev being maintained in rotation so that all sides are heated, by means of the engagement of the roller c iio with the wheel 2 upon the arm b. The hub 'i and arms are maintained in this position while the operation of forming the mount upon the arm c is being completed and dur` ing this operation the mount tube upon the arm. b will receive a preliminary heating. This heating preliminary to bringing the mount into forming position and heating it the required amount for fusing the glass, very greatly reduces the liability to breakizo age of the mount tube and thereby'greatly increases the efficiency of .the apparatus.

Upon the'completion of the mount uponthe arm c, the plunger 28 is again depressed and the armsl are moved another step forward until the succeeding pin 29 comes against Athelplunger?28 when the rollers Ic and lc 7ov apart so that uniform mounts will be pro duced, means'for limiting the movement ofk .45 be carried on continuously.

will be in engagement with the Wheels -2 lupon the arms a and b. The mount tube upon the armb has now been heated preliminarily and has been moved into forming` 5 Aposition in which it is rotated in precisely the same manner as was the'case in the next )receding positiomand When thetube ai has been sufficiently softened by the flame of apparatus F playingl u on its lower end,

'1u the rod 33 is forced upwar ly by an outward pull exerted by the operator upon the handle kThe upperend of the rod 'coming against the lower end of' the plunger. 8, that plunger is forced upwardly and, by 'reason l of the key 24 coming` against the lower end i l l l -l 'of the slot 25, the cross head l0 is carried 4upward With it. The result of thus actuating the plunger 8 is tocarry upwardly the anchor Wire supported by the upper end of the plunger, the upper end' of the anchor Wire entering the' recessvl? and being guided to the inside of the mount tube. The raising of the cross head '10 operates-to bring the forming faces of the

clampsv

13, 14, togetherabout the base of the mount tube so thatthe tube is pressed together about the lead and anchor Wires which are thus .sealed into the mount, lthe approach of the forming clamps being limited by the screws mounted in their faces as before described.

The formation of the mount having` been completed, the arms may be released and advanced another step in the manner as before described when the arm L will occupy the position originally'occupied bythe arm a. .'n this position, it will be removed from the heat andmay cool while -the mountis being formed upon a succeeding arm. The completed mount may then be removed and 40 a fresh'mount tube, lead Wires and anchor wire Vmay be placed in position as before described and the-operation which has been traced may be repeated, each arm succeeding ,another in the cycle of operations which may According;l to the patent statutes, the invention has been described in connection .with an apparatus which is considered to be itsbest embodiment, but it is to be under- "stood that the invention may have other embodiments and it should not be limited to the construction shown in the drawings.

What I claim is v l. A machine` for forming incandescent lamp mounts comprising a heater, a rotatable support for the mount tube, means for forming the mount, yand ananchor ftvire support, said anchor Wire supportand said forming means being-rotatable with the mount tube support., substantially as described. 2.
