MACHINE FOR CUTTING GLASS.
Application led November 4, 1919. Serial No. 385,720.
yTo all whom t concern.'
VBe it known that I, CARL A. BROWN, a citizen of the United States, residing at Toledo,
in the county of Lucas, State of Ohio, have invented certain new and useful ImprovementsA in Machines for Cutting Glass, of which the following is a specification.
My invention relates to machines for cutting. glass and more particularly to machines for cracking-olf the surplus neck of incandescent lamp bulbs and similar articles.
Incandescent lamp bulbs made by automatic machines, especially those made from glass tubing, usually have la neck of excess length which must be cut off before the lamp can be used. y Heretofore, removing the excess neck has been accomplished vby scoring the glass 'on a le lor similar instrument and cracking the glass oil on the scored line.
This is a comparatively slow and expensive process as it is done by hand and furthermore the length of neck remaining on the bulb varies through a comparatively large range.
According to the method and apparatus of my invention, the bulbs are inserted in a rotatable carrier which-bringsthe neck of the bulb successively into the several opera'-v tive positions. First, the neck is locally -heated on the line at which it is to be cracked-off and the neck is cut and chilled on this line. The excess neck is thenl knocked off. The bulb is automatically removed from the rotatable carrier and deposited ,in av suitable container. Among the advantages of my invention may be mentioned,
' uniformity of the length of neck, speed of operation, reliability of results and decreased breakage. Y y f In the accompanying drawing, Fig. l1 is a top plan view of a machine made according to my invention; Fig. 2 is a side elevation of the same showing the drivingm'eans; Fig. 3 isa sectional elevation on the section line 3-3 of Fig. 1; Fig. 4 is an elevation of the discharge mechanism partially in section along the line 4-4' of' Fig. 1;-Fig. 5 is a bottom plan view of the upper half of the distributing valve; Fig. 6 is a top plan view of the lower half ofthe distributing valve; and Fig. 7 is an enlarged fragmenta sectional elevation of a bulb holder.
eferring to the drawings, the .bed 10 carries the vertical bearing standard 11 through which passes the vertical shaft 12 fastened to the rotatable carrier frame 13. Near the outer periphery of the carrier frame 13 are disposed a seriesof rotatable holders 14 (eight are shown on the present machine) to which a miniature bulb 15 having a long 60 neck 16 is held by the balls 17 forced against the neck of the bulb bythe springs -18. The. holder 14 is grooved around the upper peripher so that it may be rotated at positions C] and Dby means of the belt 19. On 65 the lower end of the shaft 12 underneath the bed 10 is attached the gear 20 and the in-v dexing plate 21.
A motor 22, through the pulleys 23 and the belt 24, 'drives the pulley 25 on one 70 end of the shaft 26 on theotherend of which is the worm 27 which meshes with theworm y gear 28 on thevertical shaft 29. Above the worm gear 28 is a pulley 30 which, through the belt 31, drives the pulley 32 on the lower 75 end of the vertical shaft 33 on whose upper endv is fastened a pulley 34 to drive the belt 19 which runs over the idler pulley 35 so placed as to cause lthe belt to engage the groove in the holder 14 at positions Q and 80 39 in the plate 21 and causes the plate, and
consequently the gear 20 and the carrier frame 13,- to rotate through a small angle. The disc 38 is cut away at 40 to give clear- 90 ance to the sides of the slot 39 and the'indexing p1ate^21 is cut away at 41 between the slots 39 so as to receive the disc 38.
At position C is 'a gas ltorch 42 havinga liat jet 43 .to give a narrow horizontal flame 95 i mounted on an L-shaped support 44 pivoted at the corner of the L to an arm 45 on the standard 46 mounted on the bed'10. A spring 47, attached to the end 'of the short arm of the L and to the Wrod 48.0n` the arm 49 of 'the standard 46, tends to-keep 4the support 44 forced outward against the neck 'of the bulb. AA gai'lge 50 attached to the top of the jet 43maintains the proper distance between the jet and the neck of the'105 bulb. An adjustable stop 51 on the arm 49 permits the amount of outward movement of the support 44 to be adjusted. Gas and air are supplied through the tubes 52 and 53 to the valve', 54 attached to the jet 43.
At position D is placed a sharpened chilling wheel 55 rotatably mounted on a support 56 attached to a Z-shaped spring standard 57 on the bed l0 so placed as to press the chilling wheel 55 against the neclr oi the bulb on the line ol the heating previously described. 'lhe wheel 55 is moistened by water from a container 58 mounted lon the standard 61 attached to `he bed l0 through the regulating valve 59 -and spput 60. The bulb neck rotating in this position causes the moistened wheel to rotate thus chilling the neck on the line ot heating and so cracking the glass.
Between the positions D and E is a strilrp ing mechanism 62 (1F ig. 2)- which comprises astriher 63 attached to the end ot a rotatable rod 64: having a spring 65 wound thereabout' tending to turn the rod 6d in a direction opposite to the rotation ot the carrier frame 13. 'lhe projection 66 acts as a .stop for the inner end oit the strilrer 63 causing it normally to assume a position perpendi.
ular to the path ot movement o t' the noch at this point. As the neck ot the bulb passes the strig mechanism, the strilrer 68 hits the excess noch below the line ot cracking Yso A shaft 68 held in the and lmochs it ed' to tall into a suitable receptacle. lf the glass is not sulliciently cracked to permit the strdrer to mock od the excess noch, the striker is torced baclr'- ward against the pressure ot the spring 65 by the noch which is thus permittedto pass unbroken. Such b1 may be run through the mace a second time.
At position F is placed a transfer mechanism to remove the bulb from the holder llt and to deposit it in a slide 67 which conducts the bulb to av suitable container., Thel transiter device comprises a vertical tubular Y earring su port 69 and ha a gear 7(1) attached to its lower end driven by the gear 20 through the gear 76'. Through the tubular shatt68 passes the tubular support 7l which has a bea 72 at the upper end ot the shalt 68. Below the bearing 72 is a hall bearing 78Y against which presses a spring 74 whose other end presses;
. collapsible coeeter `89 around which -is a spring 8l ten to heep the cup separated'` trom ,the trame which permits the transfer Y mech to `he adapted mqdiil'erences in the bulb dimensions. An air pamage 82,`
through the cap 76-, connector 89:,nrm
incasso and nipple 8,3 attached thereto on the top.,
and tube 84: attached to the nipple 83 at one end and to the nipple 85 on the lowerhalt 86 of the distributing valve, communicates with the distributing valve. The lower valve 86 is attached to the trame 77 so as to rotate therewith but tree to move vertically. Springs 87 press the lower valve against the upper valve 88 which is attached to the upper end of the tudnilarv support 7l. 'lhe valve 88 has an are shaped trough 89 on its lower surface which communicates throu h the passage 90 with the lpassage 9l in t e tubular support 71. The-trough 89 extends between the nipple 85 for the position lt and the nipple for the position L, communicating with the passage 82 at position K but just cut od trom the passage tor position la. 'lhe hanne 77 is rotated by the rods 92 pass-- ving through holes in the arras ot the trame and attached to the fork 93 fastened to the upper end of the shaft 68.v The support 7l is raised and lowered 'by-the action ot the am 9d., fastened to the shalt 29previously escribed, on the roller 95 on Vone end oi a cranlr 96, pivoted at 97 whose other end is connected through 98 to a bloclr 99 tastened to the tubular support which is prevented rom rotating by the in 169 alastened in the Ablo'clr 99 and latera y restrained in an 'ope lill in the crank 96.
Air suction is created by av pp 31629.
driven by the motor 22 previously described and, through the tubo 108 connected to the lowerend ofthe tubular support 7l, is communicated to the passage 9i and, through the passage 90, trough 89 and passage 82, to the lamp bulb between positionsK and la. The
pum is cooled by water stored in a container l 4L and vconnected to the pump-by the tubes i65- and 166..
ln operation,l gl ass-halbe with excess neclrs are. 'placed in t e rotatable carrier trame at positions A and B. At position C, while the holder is being rotated the gas dame heats a narrow zone around the noch ot the -Vbulb and at position D while Ythe holder is.
rotated, the moist wheel chills 'thet noch around the heated zone causing the glass to craclr. As the bulb moves from position D to position iE, the excess neclr'hits against the Ystrilrer and is lmoclred odi falling into a convenient container. At lll, the transfer 'mechanism attaches the bulb to it `by suction and raises it, so as to clear theA rotatable can rier trame Vas the latter moves the-holder pty although these positions may he used" .for loading positions.'
