. The wall of the furnace isindicated at 20, I

and its main chamber at 20. This chamber contains glass kept in a state of fusion in any well-known manner, the level of the .molten glass being indicated at A. Ata

suitablepoint on the outside of said main furnace or main chamber is located the auxiliary tank or furnace, which communicates with the interior'of the chamber 20? by a passage 21, the inlet orifice of which I prefer to locate entirely below. the. glasslevel A, so that any impurities floating on top of the molten glass may not enter said passage,. The

but remain in the main chamber 20'. d scharge orifice 21? of the passage 21 may have itsupper limit coincident with the glass leveli k This passage 21 is shown as formed partly in the upper surface of abrick or stone 22 and partly in the lower surface of a superposed; brick or stone 28, both of these being fitted into a suitable opening-of the furnace wall 20. As indicated in Fig. 3, I prefer to have the passage 21' contracted in width from the'main chamber 2Q. outwardly, throughout the length-of said passage, while Fig. 1 shows that the bottom of said passage is inclined upwardly from the-inlet to the outlet, and also that the height of said pas" sage is first decreasing from the inlet toward the outlet, for about half the length of the passageyand then uniform or constant at the discharge portion of the passage. In line with the bottomof the passage 21, lies the inclined surface 24' of a U-shaped member;

24 located in the auxiliary, tank', and said inclined surface leads to the horizontal sur' face 24", which, together with a like surface 25' of a U-shaped trough 25, forms the bottom of a channel through'which the glass from the channel 21 may reach an inlet notch or opening 26' at theupper portion of an upright receptacle or pot 26, preferably cylindrical in itsv main portion and contracted conically at the lower end, at which is located the glass outlet or nozzle 26'' The member 24 is spaced from the pot 26, and each of these parts is formed with an upwardly-open recess in which the trough 25 is seated. The' nozzle 26 preferably projects slightly beyond the bottom of the auxiliary tank or auxiliary furnace. The pot 26 is located centrally within the semi-cylindrical upper portion 27 and the cylindrical lower'portion 28 of a surroundin wall, forming with said pot an annular c amber 29, provided at its lower portion with two diametrically-opposite inlets 29, preferably tapering inwardly, through which a burning mixture of air and fuel (say, gas) may be injected into said chamber 29. Fuel is illtroduced through the outer pipes 30, and air through the inner pipes 31, provided with perforated heads 31, such air being under pressure. The upper end of the pot 26 is held in position partly by the trough 25, which braces said pot against the member 24,

- vand partly by a refractory wedge 32 set between a lip 26* on the pot 26 and a projection 33 on a top member 33, which latter extends above the upper edges of the pot 26, trough 25, and member 24, said upper edges being flush with one another and with that 0t the stone 23. Atits lower end, the pot 26 is fitted into, and held by, an annular bottom member 34. The auxiliary tank is preferably encased in' sheet metal, a bottom plate 35, apertured for the passage of the nozzle 26", co-operating with a vertical wall or shell 36 cylindrical at its lower portion, while its upper portion is semi-cylindrical in front and formed with two parallel plane members at the rear, as shown in Fig. 3. The rear ends of said parallel members are shown secured to the furnace wall 20. The auxiliary tank is further held in position by straps or braces 37 secured at their ends to the furnace wall 20 and converging therefrom forwardly to engage the curved surface at the upper portion of the shell 36v Preferably, this shell is not in contact with the wall 27, 28, but spaced therefrom by an asbestos layer 38. Between the wall 20 and the lower portion of the shell 36, a horizontal supporting member 39 may be placed under the bottom member 27 of the surrounding wall of the auxiliary tank or furnace, I

On the top member 33 are supported three arched transverse members 40 and 41 respectively, bridging a horizontal channel 29 which extends rearwardly from the upper portion of the chamber 29 and communicates with the interior 20' of the main furnace chamber by means of a duct 42. The member 40, adjacent to the wall 20,-is preferably in position permanently, but the two outer members 41 areremovable, being set loosely on the top member 33' and provided with handles or eyes 41' for lifting them more readily. The member 40 is provided with an opening or notch 40 through which extends thevertically-movable gate 43, lifted and lowered by any suitable mechanism (not shown). This gate does not fill or block the channel 29", so that combustion gases may flow through said channel even" when the gate is lowered; but in its lowered position the gate rests on the surface 24" of the member 24, forming a glasstight joint therewith, and is also borne by the pressure of the glass in the main chamher 20, against the rear surface of the U- shaped trough 25, thereby preventing the glass from the chamber 20 passing into the trough 25 and pot 26. On the outer portion of the top member 33 further rests a transverse or bridging member 44 provided with openings 44 in line with the chamber 29 and with the pot 26 (see Fig. 2), these openings being normally closed by bricks such as 45 which are set on the bridging member loosely, so that they may be moved aside readily to uncover any one of the openings 44?, for the purpose of inspecting the chamber 29 and the pot 26, or of cleaning said parts. By removing the arched members ill for the passage of the trough 25, so that a new trough may be substituted readily when desired. Similarly, if 'in addition to the members 41 I remove the member 44, the resulting opening is large enough to allow ready access to, and the insertion and removal of, the pot 26 together with the trough 25. In order to obtain a tight joint between the trough 25 and the member 24 on one hand, and the pot 26 on the other side, I prefer to provide a strip 46 of clay or other luting substance at each of the four vertical edges of said trough, see Fig. 3.

Against the outlet of the nozzle 26 is fitted a stationary nozzle plate or nozzle guard 47,provided with a perforation in its center to register with the nozzle outlet when the pot 26- is in position, it being understood that the nozzle is set loosely on said guard. The latter may be secured to a' stationary plate 48, fastened to the bottom plate 35, as by screws 49, and formed with parallel guides 48', between which is adapted to reciprocate horizontally the carrier 50 of the knife 51 moving across the perforation or outlet of the nozzle plate 47. The

hereinafter.

In orderthatany glass which enters the chamber 29 through cracks or leaks, may not aciumulate in said chamber and clog it, I have provided a glass-outlet at; the bottom of chamber 29, said outlet consistmg of an nooacoa through which the screws 49 pass, elongated in one. direction.

The rod 54, which is guided in a sleeve or bearing 48 on the plate 48, carries at oneend a longitudinally-adjustable sleeve with a transverse pivot pin 55' for links 56 the other ends of which are connected pivotv ally at 56' with an arm 57 mounted loosely on' a shaft 58 journaled in stationary bearings,-such as 59, 59, and 59". The arm 57 has, a segmental guide plate 57 with an opening 57 adapted to receive the end of a coupling pin 60 mounted to slide in a sleeve 61 formed on an arm 61 securedto the shaft 58 rigidly. The pin .60 has a head 60 for "pulling it out of the opening 57 ",a coiled spring 62 normally keeping said pin in said opening, so as to couple the arms 57, 61. When the pin has been withdrawn from the coupling position, it maybe held in this uncoupled position by giving it aslight turn; this will bring against the outer end of the sleeve 61', a transverse pin 60'. carried by the pin 60 and normally extending through slots 61" extending lengthwise of the sleeve 61. Atanother point, say between the bearings 59' and 59", the shaft 58 carries rigidly a crank arm 63, formed with a projection 63' adapted for sliding contact with a stationary' guidc 64 on a base 64. The arm 63, near its free end, carries a roller 65 adapted to be engaged and operated by cam portions (more fully described hereinafter) o'n'two cam disks 66 and 67 concentric with 'a shaft 68 journaled in stationary bearings 69, 69'. The cam disk 66 is rigidly secured to the shaft 68, as by means of a nut 70 screwing, on a threaded portion of the shaft and pressing a toothed surface of the disk into engagement with a correspondinglytoothed surface of a holding member 71 keyed to the shaft. Likewise. rigid upon the shaft 68 is apinion 72, in mesh with a spur gear 73 mounted to turn about an axis 7 3 on two arms '74, 75 which are normally stationary, but mounted I loosely on the shaft 68, andlcapable of adjustment about the axis of said shaft, as will be set'forth presently. The two arms 74,75 are connected rigidly. as'by a bolt 75, so'as to compel them'to move in unison, although the pin or pivot 73 might suffice for making this connec-- tion. Rigidly connected with the spur, gear 73 is a spur pinion 76, in mesh with a spur ar 77 mounted loosely on the shaft 68. l'le gear 77 is further in mesh with a spur pinion 78 secured rigidly to a shaft 79 journaled in a-bracket 80 extending from the base 64. On this shaft 79 is also secured rigidly a spur gear 8l, meshing with a spur pinion 82 which ismounted loosely on the shaft 68, and is rigidly connected with the cam-disk 67. On an extension 80 of the bracket. 80 is mounted pivotally, at 83, a sleeve 83' in which a shaft S L-is mounted in such amanner as to allovv rthe shaft to turn, while preventing its longitudinal movement. At one end, said shaft is connected with any suitable mechanism for operating it, and for the sake of simplicity, a handwheel 84; has been shown as secured rigidly to said end of the shaft 84. The other end of the shaft is screw-threaded, and extends through an internally-"threaded sleeve 85, mounted .to

swing about the axis 7 3, that is to say, said sleeve is loose both with respect to the gears 73, 76 and with respect to the arms 74, 7 5. The ratio between the diameters of the gears is such that, normally, the two disks 66, 67,

whileone of them is not secured to the'shaft.

68 rigidly, will both rotatein unison with gears 77 and 85 will have the same angularvelocity, thus causing the gear 85, under normal conditions, to rotate as if it were rigidly secured to the shaft 68. connections might be devised for causing the two cam disks 66, 67 to rotate in unison normally while allowing one of these disks (in this case the disk 67) to be adjusted circumferenti'ally in relation to the other disk,

Of course, other without interrupting the driving connection.

' In the particular example illustrated, the loose disk 67 is held against movement lengthwise of the shaft 68, by being fitted between the pinion 82 and a collar 86, held to turn with said shaft, as by screwing said collar on the shaft, and locking it against rotation by a screw 87 threaded into the collar and pressing inwardly against a clamping member 88, preferably threaded to fit said shaft. I

The shaft 68 is driven in any suitable manner, say by means of-a pinion 89 secured to said shaft rigidly and meshing with a crown gear 90 on. a rotary member 91, which maybe a permanently-rotating part of this bottle-making machine'the molds of which receive the 'molten material discharged from the nozzle 26" and cut off by theknife 51. v

The disk 66 has a cam 66" which by acting on the roller 65 swings the arm 68 and the shaft 58 in such a direction as to carry the knife 51'ito the position in which on the other side and thus rockthe shaft 58 in the opposite directionto' bring the knife 51 to they-position in which it clears the nozzle outlet and allowsthe molten glass .be varied to issue therefrom. The action of the two cams 66, 67 "is not immediately consecutive,

so that after the-cam 67- has acted, and before the cam tifi shifts ,the knife to the closing position, -there is a. certain interval. of time during which; the knife remains stationary in the position in which glass may flow from the -outlet:26";.-.=Obviously, the length of this -='or interval may turning the cam 67" to a different position, circumferentially, relatively to the cam 66.. This, is accomplished,

even while the machine is'in'operation, by turning the shaft 84 in one direction or the other, so as to increase ordiminish the angular interval between the cams 66, 67, and thus cause the nozzle/outlet 26" to remain open a greater or smaller length of time. During such adjustment, the axis 73 of the gears '73, 76 moves in the arc of a circle having its center upon the axis of the shaft 68, that is to'say, the axis of the gears 72 and 77 which are in mesh with said gears 73 and 76 respectively. Thus the adjustment mentioned does not affect the proper meshing of these gears, and the drive of the cam disk 67 is uninterrupted while the adjustment is being. made.

In order to prevent any accidental tuming of the adjusting shaft 84, I may connect rigidly with the sleeve 83. as by means of a bar 92, a split collar 93, which by means of a clamping screw 94 and nut 95 may be caused to grasp the shaft 84 so tightly as to prevent its rotation. This is the normal condition of the parts. When it is desiredito turn the shaft 84 for adjusting the cam disk 67, the nut 95 is loosened, and after the adjustment has been made, the nut is tightened again to guard against accidental disturbance of the adjustment. This safety or locking device is preferably placed in the nei hborhood of the device (such as the hand wheel 84') which serves for operating the adjusting shaft 84; thus both the locking device orsafety device will be .ieadily accessible to the operator from the same point. o

On the shaft 58 is mounted loosely an arm 96'provided with a handle 96' to enable the attendant to swing it to one side or the other. 'With this arm is connected pivotally at 96". a connecting rod 97, preferably made with joints 97 enabling it to be lengthened or shortened. The arm 96 is held against movement lengthwise of the shaft 58, on one the actuating device and In practice I nected pivotally at 101' with an arm 101" on a carrier 101, mounted to rock about avertical axis 1-02;' for instance, this-earner mayfrock on a stud-or axle, securedto the bottom of the auxiliary'furnace. The carrier 101 is made-with two parallelsleeves 101* side by a collar 98 securedto said shaft, and i in which are set, adjustable longitudinally,

the ends of. rods 103, held in position by set screws 104. The other endsv of-said rods .are secured rigidly toa discharge member '105, say by fitting them tightly into sleeves 105 on saidmember. The discharge memher is provided with an inclined channel or trough 105", and to one side thereof is secured rigidly "a transfer channel or funnel 106, preferably with a downwardly-contraded-passage, I have .represented the transfer funnel with a jacket 106 towhich a cooling medium, say water, is supplied through an inlet 107. The outlet of the water jacket 106' is connected with a pipe 108 extending across the upper portion of the trough and perforated to discharge water into said trough. In one position, as

shown in-Figs. 2 and 1 5, the funnel passage is in verticalalignment with the axis B of the nozzle 26", so that (when the-knife 51 is retracted) the glass issuing from the nozzle may flow through the funnel passage, say into a mold (not shown) registering at that time with the funnel and located below it. In the other position, see Fig. 14, the funnel 106 is out of registry with the nozzle 26", and the axis B of the latter will be in alignment with the trough 105", so that any glass discharged from the nozzle26" at this time will flow into the trough and be de flected or conveyed thereby to any suitable place, say into a water pan (not shown).

The operation will be-readily w der-stood.v Theglass in the main chamber 20 iskept in a state of fusion by any well-known or approved means, and always extends into the channel 21, whether the gate 43 be open or closed. When the gate is open, the glass passes on through the trough 25 and notch 26 into the not 26, filling the same at the time the knife 51 closes the outlet of the nozzle 26". The portion of glass thus retained in the auxiliary tank is strongly heated by the combustion of fuel in the chamber 29. prefer to use a higher temper" ature in the auxiliary tank than in the main furnace so that the molten mass will have a higher degree of fluidity in the auxiliary tank, thereby facilitating the subsequent from the chamber 29 return into the main chamber of the furnace, through the channel 29, 42. If any combustion gases should blow out at the openin 40 or at leaky points, no serious harm will result; as a matter of fact, however, there is little likelihood of any material escape of combustion gases, for the reason that a strong draft is maintained in the chamber 20, which tends to draw in outside air throu h any leaks, rather than to allow the com usti on gases to escape at such points. When the knife 51 is retracted to clear. the nozzle'outlet, the glass will flow through the funnel 106 into the mold. or other receptacle in position at that time. 'In its passage through I:

the funnel, the glass will be cooled slight but this is incidental, that is, the purpose is to cool the funnel rather than the glass, as a protection against injury to the funnel by the excessive heat.' After'a suitable interval of time, the knife 51 moves in the opposite direction and cooperates with the stationaryplate 47 to cut off the stream of molten glass issuing from the nozzle 26", and in this position the knife forms a valve or shutter closing the nozzle outlet. In the construction indicated, the movements of the knife occur at regular intervals, being timed by the operation of themachine carrying the molds to which the glass is delivered. The time interval between the moment when the knife is retracted to clear the nozzle,

. and the moment when the knife, in its advancin movement, again closes the outlet, determines the amount of glass delivered at each individual operation, so as to properly fill the individual molds as they are brou ht successively to the filling position. y means of the adjusting shaft 84, the time of opening the nozzle outlet can be set to occur sooner or later, while the time of closing the outlet remains unaltered. The time interval between these two moments is therefore variable, to adjust the amount of glass delivered at each filling operation, as may be desirable when molds of different capacity are used at different times, or to compensate for greater or smaller viscosity of the glass resulting from differences in its composition.

Preferably, a stationary guard or deflector 109 is provided on one side of the nozzle outlet, to catch and direct into the funnel 106 any glass which the knife 51. in its advancing movement may force aside instead of-cutting it off, as intended. It will be understood that the adjustment of the time interval during which the nozzle remains open, ma be effected while the machine is in operation, and without stopping the rotation of the shaft 58.

,It will be understood that during the normal operation of the machine, the transfer funnel 106 remains in registry with the nozzle outlet, to receive the glass therefrom whenever the knife 51 clears such outlet.

.Under certain special circumstances, however, it may not be desirable to have the glass flow into the molds or like receptacles, say if the operation is-to he stopped temporarily. In such a case, the arm 96 is actuated by the attendant to swing the funnel 106 away from the nozzle axis B, and to bring the trough 105" beneath the outlet of the nozzle, and. therefore in position to catch any glass issuing from the outlet. Such glass will be deflected by said trough to a place of disposal, say a water pan (not shown), and the water issuing from the perforations of the pipe 108 will not only preserve the trough from being injured by the heat of the glass, but will also cool'the hot glass by direct contact.

Certain features shown in the present application are also disclosed and claimed in Patent No. 1,388,654, granted to me August 23, 1921.
