is an enlarged vertical section of a portion of the machine, showing the manner of vmountin the head-carrying frame, the means for driving the heads, and gas and air connections with certain of the burners. Fi 4 is a perspective view of the pedestal an portlons of the parts mounted thereon, showing 'the driving belt arrangement. Fig. 5 is a' horizont-al sectional View on line 5 5, Fig. 4

Fig. 8 is a vertical section of the rotary lbulb-holding head of the neck trimming device taken on line 8 8, Fig. 2. Fig. 9 is a horizontal section on line 9 9, Fig. 8. Fig. 10 is a detail sectional view of the burner-supporting frame ot' the neck cut-off'device. Fig. 11 is a detail sectional view of one of the burners.

Similar reference characters are employed I to designate corresponding parts throughout the views.

Referring to the drawings, A designates the standard or supporting column of the machine on which the various parts thereof are mounted, and preferably the said column consists of a suitable length of plpe whlch A has its lower end threaded in a base plate or disk l which is secured'by bolts 2 or the like to the. floor.' On the upper end of the pipe standard is a cylindrical head 3, which, as shown in Fig. 3, has a tubular extenslon 4 that forms a pivot. on which rotates the` head-carrying frame or spider B. The head 3, together with its extension, inay be considered as a part of the standard of the machine, as they are ,rigidly secured to the pipe section of the standard. At the root portion of the extension or pivot 4 1s formed an annular shoulder 5 on which bears a ring 6 having its upper face inclined so that the ring` constitutes a Cain, which, by rotation, causesthe head B to rise or fall for the purpose ofQpositioning the lamp parts 1n the heads C in proper relatlon to the burners. Interposed between the hub 7 of the frame B and cam 6 is a collar 8 which 1s feathered on the extension or pivot 4 and which has its under side inclined to conform to the cam, so' that as the cam is turned,

limited by an adjustable stop 37 disposed' diametrically opposite from the follower to engage the sleeve y34. When a driven wheel 19H is not engaged with either one of the driving..wheels30, the latter are inclined or tilted to the dotted line position, Fig. 3,'and

as soon as the wheels 19- are brought into 0 erator turning engagement with. the driving wheels by the I the head B, the driving w eels',will yiel inwardly against the ten- Sion of the followers 36 until the wheels are frictionally en ged. The rubber tires or coverings of t e driving wheels also compensate for-slight inaccuracies and they cooperate with the spring-pressed followers to insure a firm engagement of the driving with the driven wheels. The means for rotat'ing the driving wheels 30 is clearly shown in Fig. 4, and consists of a hollowrotary shaft 38 which is mounted to rotate on a fixed arm 39 fastened' to the standardby` a two-part collar 40 which is Va-,djustably clamped to the standard, and on the shaft 38 .is a pulley 41 driven from an suitable source of power by a belt 42. A so on the shaft 38 is ,a pulley 43 around which passes 'a belt 44 that extends upwa-rdly'to the pulleys4 33 on the friction drivin wheel shafts. The plane of rotation of the w eels 33 is hori- Vzontal, and hence at ri ht angles to the plane of rotation of the pu ley l43, and therefore The heaters are of the usualblast type and consist of gas 'jet nozzles 46and blowers 47 which are so related to each other as to direct a plurality of ame blasts upon acommon point towhich the lamps are successively brought to be heated. The preliminaryburner'or heater and the outer section Vofthe final burner or heater are supplied wlth gas and air, respectively, through pipes w 48 and. 49 which form supports for the nozzles and blowers. These lpipes radiate from the enlarged yportion or cylinder 3 of the standardfrom which they receive their supplies, and they also form supporting brackets for the bearing blocks 32 on which the latter are adjustable inwardly oroutwardly on the said brackets to bring the friction by a partition 51 into an upper gas chamber 52 and a lower air chamber 53, which latter communicates with the pipe sect-ion of the standard that has its lower end closed by a plug 54. These chambers are connected, respectively, by pipes and 56 with a source of gas and an a1r pump and they serve as pressure equalizin devices so that the flames at the heaters wil be more or less uniform` -air pump to prevent pulsations in the air pressure at the burners. The inner section of the main heater is supported by an arm 57, Figs. l, 2 and 4, on the collar 12 at the upper end of the standard, and the gas and air are supplied4 from the chambers 52 and4 53 through

conduits

58 and 59 extending longitudinally of the pivotal extension 4 of the standard, there 4being hose connection between the upper ends of these passages with the burner nozzles and blowers. The supply of gas and air to the chambers 52 and 53 can beregulated by

valves

60 and 61 in the

pipes

55 and 56, and the ditlerentnozzles 4and blowers can be controlled by regulating iwalves 62, one of which is'clearly shown in ig. 11. y

The device for cutting ofi" or trimmin the neck extensions of the bulbs is mounte as shown in Fig 1,I on the standard Arat a point adjacent the middle thereof and is supported on the.outer end of a horizontal arm,63 secured to the standard by a clamping collar 64.' The outer end of the arm 63 1s provided with a bearing ring 65 which has its axis vert-ical to receive the stem or spindle 66 of a rotary head 67 in which the bulb is supported, the head being constructed somewhat after the fashion of the heads C to hold the bulb in inverted position, so that the flames from the heaters H2 'can be directed on the neck and cause 'head 67 to insure free rotation of the latter.

65 is'castor otherwise formed with The ring y-disposed horizontal arms 72 each opposite driving wheels into proper relation with the of which has

separate chambersy

73 and 74 driven wheels of the lamp-holding heads C. and are connected byy hseorothercondults wardly and 4are connected by a tie bar 50 so The pipes have their outer ends turned upt 75 and. 76 with branches'ofthe gas andair late the supply of gas and air to the heat-'- ers H2.' The gas jet nozzles and blowers of the heaters. are screwed into or otherwise secured to the

chambers

73 and 74 so as to' receive gas and air therefrom.

The machine, as herein illustrated and described, requires two operators seated at opposite sides -of the 'machine,' the principal operator being adjacent the final heater to attend to t-he sealing of the lamps and vthe assistant adjacent the cut-off or trimming device. Assuming that the heaters are burning and that the belt and pulley transmission is operating, the assistant places a bulb to be trimmed in the continuously rotating holder 67 to cause the neck of the bulb-to be meltedv off. In this operation, the neck of the bulb closes and must be blown open by the assistant blowing a puff of air through the tubulature after removing the trimmed bulb and before it is placed in that head C which is in front of her. Before the trimmed and blown bulb is placed in' the head C, a filament-supporting stem is applied to thel upper end of the rod 23 of such head, the bulb being slipped 25 downwardly over the filament until it comes to rest in the seats or

openings

21 and 22 of the head. The carrier or frame B is then given a quarter turn to .bring the head with the lamp part assembled therein opposite the preliminary heater where it remains during the time required for the assistant to prepare and position vthe parts for the second lamp in the succeeding head. Thereafter the carrier or frame Bis given another quarter turn to throw' the first lamp opposite the final heater and the second lamp opposite the preliminary heater, and at this point, the main operator gives her attention to the sealing of the first lamp. She notices the position ofthe assembled parts of the first lamp with respect to the l ame of the final heater, andv if not in proper relative position, she `turns the handle 9 of the cam-6 to raise orflower. the carrier or frame B, and hence the lamp withrespect tothe flame of the `inal'heater which is stationary. The glass of the bulb and stem areV thus melted and as soon as the fusion of the parts'fiscompleted to form a '.50 seal, the lamp is removed 'from` the heater by the principal operator turning the-head carryingframe B to thus bringthe second `lamp tothe final-heater andthe third lamp, yvvlaichg-fhas. been assembled in the meantime 55. bythe assistant operator, k,to the preliminary heater-*.3 ",Thenished lamp is then` removed byv the' principal operator .who straightens or draws out the filament-supporting stem if she nds-it necessary, and in the'empty. head shei supplies v afilament-supporting stem which is carried to the assistant as the empty Head moves to a position in front of' her. These operations g'o on in proper sequence very expeditiously so that a large number of lamps ,canv be turned out without From the foregoing description, taken in` connection with the accompanying drawings, the advantages of the construction 70 and of the method of operation will be readily apparent to those skilled in the art to which the invention appertains, and while I have described' the principle of operation of theinvention, together with the appa- 75 ratus which I now consider to be the best embodiment thereof, I desireto have it un` derstood that the apparatus shown is merely illustrative, and that such changes may. be made when desired as are within the scope of the claims appended hereto, .and many features of the present invention are Well adapted for stem making machines.
