-To c/,ZZ 'wzomz't may concern Be it known that l, CHARLES C. STU'm,

residing atv Norwood, in the county of Hanr 2 ilton and 'State of 01110,.. a citizen ol theV United States, have invented or discovered y certain, neuY and useful 'Improvements in Machines foryGathering Glass, of which iinprovements the following is a specification.

As' is Well known ylo those ,skilledv in the art it'isimpracticable to gather glass'by a i' ladle or rod 'from 4a molten mass Without? 'the form-ation of strands extending from the gather to' the mass of glass.' When this l strand is severed a. portion drops back into Athe mass and it requires time for such re- Z- turned portion to become 'incorporatedwith i And further the rod or ladle being colder than vthe glass, portions of the.: glass adjacent to-the vpoint of immersion of"V the mass.

the ladle or rod'r become chille(1 to suclia degree, that if a second gather is made-im? 1 mediately at the saine point as the 'firs-t the glass of the second .gather Will lack uni-f formity andlines, etc.,Will appear inthe article formed therefrom.

objectv the provision in an automatic gath-v ering machine of means insuring the gathering of the desired amount of glass from different points of a molten. glass supply,

employed for shift-ing vthe swinging the ladle 9 iscarried byrodlO having its i rear 'end niovabljy' lmounted in a sleeve 'll which is `provided with trunnions having their journals mount-edili4 notches in the arms 13. These arms are secured to the swinging' member 4 which yis' pivotally mounted on the upper slide 5 .mounted on the slidefl. This slide il, is in turn mounted on a frame G which may be stationaryv or may be reciprocated dependent. on the number and arrangement of molds to b'e'charged as clearl)7 shown and' described in the Let- The upper or toolV slide is reciprocated by screwv S which is .preferably rotated 'by mechanism substantially7 similar to that employed in the patented machine and the lovver or tool tipping slide 4- is moved vforward b v the slide 5 through 'the medium of springsjld, so that the slide 5 mayiuove independent' of slide 4 as, will be hereinafter described. The rearward movement of the slide 4 is also etlectedbj slide 5 by means of a stop 1S on slide engaging a. por-tion of slide 4 or in anyY other suitable manner.

AThe tool carrying sleeve ll is provided with an angularl)Y arranged arm 14 pro .vided atj'its loxveizend with lateral projections, preferabliT in ther form *ofV rollers engaging guide Ways l5, which is carriewi on a slide i9 mounted on a'curved guide 2001i the front end of the loiver sli-de 4, the center of curvature of the ouide coinciding with the center of movement of the swinging member 4: -As will be seen by reference to Figs. l to '-1 the arms 13 on which thelacre is carried 'While being shifted back and forth, extend through slots 2l in the slide 19, thus insuring coincident and equal movements of the slide "i9 and the swinging As fully set. forth in the pan. referred to the slides 5 el move fore/*ard together until t? means ladle oi7erftheglass supply, at'which time the further movement i afield@ abad In the embodiment of my invention which is adapted for supplying molds arranged in tandem as' shownand described in. the patent referred to, the gathering" of glass is eected on opposite lsides, of thel line `on which the molds are arranged and hence provision is made'V for shifting the swinging member 4a and the tool carrying rod to oneside o r the other of the line on which the molds are arranged, as the slides 4 and' 5 move forward, and to bring said parts into alinement with the molds after the for shifting the swinging member "consists of arms 22 so pivotally mounted lat the forward ends of guides 23 that lwhen in midposition the inner edges of these arms will be in alinement with the inner edges of the guides onto which rollers 24 will be directed by the arms as the slides 4 and 5 move back. The arms -are-provided with angular extensions 25 to which are connected rods 26 provided at their rear ends with straps surrounding eccentrics 27 oppositely secured on shaft 28. On this shaft 28 is loosely mountl ed apinion 29, which when rotated in one ldirection will effect theI .rotation of the shaft through the medium of a pawl 30.

Thispawl ismounted ina recess in the inion in such manner as to engage shoulders on the shaft, as shown in Figs. 6 and 7 The reverse movement of the pinion on the shaft is effected by a spring 31. This pinion is operated to shift the eccentrics27 by a rack' 82 which is pushed back by the slide 5 as it approaches the rearward limit of its movement. rIhe relative arrangement of the shoulders on the shaft and th'e movement imparted to the rack by the slide 5 will depend uponpthelateral movement to be imparted to the gathering tool for the succeeding gather. By the shifting of the eccentrics the arms-22 are shifted from one position to the other, while the slide 4 is in its rear position, so that when during the next forward movement of the slide, the rollers 24 move into the arms, the swinging member 4a, the ladle rod, the slide 19, etc. will be shifted to one side of the, median l line of the machine.

While the rotation of the gatherin tool to collect the molten glass may be e ect'ed employ the means set forth in the patent referred to and shown in Figs. 1, 3 land 4. On the rear end of the rod 10 is secured a drum 56 to which are attached two `straps 57 passing in opposite directions to a second drum 5S .loosely mounted on the stud 59 secured to the arm 14.- A disk.60 is secured to the drum and is connected by a universal joint 61 .to one member of a telescopic shaft consisting of a rod 62 and-a sleeve (S3-keyed one 'to the other so as to rotate in unison but to move longitudinally independently one of the other. The sleeve 63 is connected by a universal joint 64 to a short shaft `mounted. .in the rear end -of the upper slide 5. A sprocket .wheel 65 on this shaft is operatively connected by a chain tol a corre-' sponding wheel 66l so mounted on the shaft A6( which extends the full length of the machine, as to be rotated thereby and movable along theA same by the slide A5. A 'It will be readily understood that ifthe intervals of time between successive gathers are sufficiently long to permit of the restoration of the molten glass to normal or workingcondition, only two changes of position ofthe gathering tool will be necessary. But asin most cases the time interval between successive gathersl will be too short for a.

4p'roperrestorat-i'on of the glass,provision is made for other changesv ofthe position of the tool in gathering.- As for example the depth of movement of the tool into the furnace' or its forward movement over the glass supply may be changed for,l the second, gather following a lateral change of position as above described. This change in thev extent of movement of .the tool is effected by varying the forward movement of the slides 4 and 5. In the construction 'shown herein, the movement'of the slides is effected vby the screw 8, as hereinbeforestated. The

construction for' rotating the vscrew 8 is preferably as set forth in the patent referred to, zi'. e. a pinion on the screw is driven through a sprocket chain 150 by a pinion on the lshaft 151, ywhich is operated through suitable gearing by the motor driven shaft The stopping, starting and direction of movement of the shaft 151 and consequently of thel slides 4 and 5 is controlled by cam grooves on the drum 169, and connections fromsaid 'grooves to starting and reversing'clutches as fully shown and vdescribed in said patent. In theembodiment of the invention set forth herein a dipping or gathering cycle will involvetwo long and two short strokes or movements ofthe slidesv 5 and 4 and consequently the grooves in the drum 169 are constructed for four- 'periods'.

But when using my' improved gathering.

mechanism in connection with a three unit shaping machine as shown and described in the patent referred to, the frame 6 will `be vshift'edonly two times during a dipping cyele. as said frame is not moved when the first mold of the. series is charged. As in the patent, this slide is ieciprocated preferably by a threaded shaft-.145, driven 4from shaft SiL which has jkeyed thereon 'a pinion HG intermeshing Vwith a pinion 147 looselyvniounted on shaftl ll'fbut adapted to be operatively connected thereto by -a Clutch 14:8.' This clutch is shifted by cam 169?.- This cam is loosely mounted-'on a stud'aiid is adapted to bev rotated through a sprocket chain by a vsprooket. wheel 3 4 on the shaft'e'arrying the drum .169. The ineclia-. nism operating the threaded shaft- M5 is sooonsti'iioted and driven, that tlie'p'fra'me 6 will shifted. during two dipping or gathering' movements, but will be stationary during the third gathering and mold charging movements V i The movement of tlietool down to gather glass is effected by checking-the movement ot' tlieloiver slide Ll' While the upper slide continues itsforward movement, The stop ping of the forward Amovement of the 'lovver-V oi'- tipping slide is etieeted. bysuitahle stops,l

the position of one of ivhich must be ol-ianged to correspond with vthe change "inthe foi'- vward-movement of the slides lieieiiibefore described. and also to jvary .the ldovvnimi'tl movement of the tool, as'the level ofthe glass in the supply changes. struction shown, I which is preferred altho'u gli other forms may beused, the niecl-'ianisni for 'arresting slide feat-the endsjof the shorter tool movements is carried in part by said slide and in p art'byl the frame (3. The elements'earried by the slidel .consist ofpa nutprovided with a lateral extension and -inonnted on a threaded .sleeve'BG through v portedin bearings 3S secured to the frame which passes a rod 3.7 having its ends sup of the machine. The, ends of the sleeve are so held iii lugs 3S?, on the slide'las to move v the sleeve along the rod 3T but permitting the sleeve to be rotated by the rod, to which dit is splined, foradjusting vthe position of the nut.V The other elements ofthe stop Iiiechanisin` consists of a vertically movable slide l() .provided with a pi'.tijetti n -ll eX.,- teiiding vinto a cam groove in'the disli 42 loosely mounted on the stud 43.' The rotation of the dish to move the slide into and ont ofthe ,path of movement' of the-nut or Y stop member 33 is elfected by the shaft 2S .throngh suitable sprocket Wheels' lie and chain l5. as shown iii Fig. G. Thefgroove in disk l2 is lso constructed, and the' disk is so rotated that the slide -lO' will extend into the path of movement of Athe stop l5 during two sucrev e forward moveinc ts of the slides l and 3 and will he ivi'thdraivn during the -next tvvoior longer forward movements of the slide -..l-, which is then stopped to dip the tool by tile fixed Stop lli.

it is characteristic of my iniprovementl va ryiii g the that the point. tif-gather an be'varied 'either by .sliifthigthe tool carrying devices laterally or by vary-'nig the length of .sti'okeof sueh devices, andy that by suitably combiningy such change producing means of position a' plurality of pointsof gathering -iiiay vbeobf'l vtaiiiethaiid in that "any rendering it. possible between suoto reduce the intervals of time cessive gathers.4

[t will be iiiiderstoodvthat suitable means are to be employed 'for removing the glass' from the gathering tool andtraiisterring'it to the molds. is for example ivhe'n using my improvements in connection ivith the apvparatjus shoivii' and described 'lii the patent referred to the glass-may be charged into the molds 'iii the manner therein set forth. 'l`he'movenient" necessary to gather the glass is imparted to the tool in any suitable inaniier after the' latter Ahas beenv brought into operative relation to the glass supply.'
