SEECIFICATION forming part of Letters Patent No. 767,935, dated August 16, 1904.,

Application filedJune 8, 1903. Serial No. 160,603.v (No model.)

To all rah/07%. it flea/y concern:

Be itknown that I, ROBERT GOOD, J r. a citizen of the United States, residing at Olarksburg, in the county of Harrison and State of West Virginia, have invented or discovered certain new and useful Improvements in Machinery for the Manufacture of Glassware, of which improvements the following is a specification.

My invention relates to machinery for the manufacture of glassware; and it consists in the construction and arrangement of mechanism hereinafter described and-claimed.

In the accompanying drawings, forming a part of this specification, I have illustrated my invention embodied in a machine for the manufacture of hollow articles of glassware bythe well known pressing and blowing process wherein a mass of molten glass is first pressed to a preliminary shape and the body of the pressed blank then blown to finished form. The machine is practically automatic in its action, is of strong and durable construction,

and has a large productive capacity of articles of superior quality at a very small expense for operation and repairs. I

The general organization and operation of this machine, which I here show and describe vas thepreferable embodiment of my invention,

is, briefly stated, as follows: The pressing-plunger is provided with a passage through it conto' another blowing-point more or less distant] therefrom. The passage of the air through the plunger also materially contributes to keepingthe latter at the proper temperature, and I have in this respect also found it more satisfactory than the water-cooled plungers now' commonly used. The form of plunger employed 1s, however, not an essential part of my inventlon, since a separate blowing member maybe employed, if desired. 1 have illustrated and prefer to use such a plunger as is shown and described in United States Letters Patent No. 585,469.

Below the plunger is mounted the mold-support or table, which in its preferred form, as

herein illustrated, is rectangular and is reciprocated lengthwise. Upon the table are mounted a sectional blank or press mold and a plurality of sectional finishing or blow molds. I prefer to use two blow-molds, and I have herein shown such blow-molds arranged one on each side of the press-mold, so that by the reciprocation of the table first the press-mold and one of the blow-molds and then the pressmold and the other blow-mold may be carried in succession into position under the pressing automatically opened and is carried away by the movement of the mold-support, leaving the pressed blank suspendede'n situ in the neck-mold in the path of the approaching open blow-mold. The blow-mold is then closed about the blank, the blank blown to finished form, the neck-mold opened, and the mold-support moved in the reverse direction to return the press-mold, witha fresh charge of glass, into position under the plunger. The neck mold is again closed, another blank pressed, the mold-support moved another step, and the other blow-mold closed about the second blank. The first blow-mold being then at the outer limit of its travel, it is opened to discharge its finished article, and the second blank having meanwhile been blown and the press-mold closedand charged the machine is ready for a new cycle of operations. The

press-mold is thus employed in the formation of the pressed blank for each article which is made, while the blow-molds are used alternately. 7

Since in the arrangement of molds above described the press-mold is to be alternately charged on opposite sides of the operatingpoint, 1 arrange on each side and immediately above the initial position of the press-mold a cutter, to be hereinafter described, for cutting the molten glass from the gathering-iron as the latter is held over the press-mold.

As the gatherer drops the glass into the press-mold he depresses a treadle, which by its initial movement operates the cutter to cut off the glass and then sets the machine in motion. hen the. pressed blank has been blown and the neck-mold opened, the machine is automatically stopped. The gatherer then charges the press-mold on the other side of the plunger and starts the machine again, and the reverse movement of the mold-support to produce another article takes place.

In the accompanying drawings, in which the same numerals are employed to designate the same parts in each figure, Figure 1, Sheet 1, is a front elevation of the machine with the mold-support at the right-hand limit of its movement. Fig. 2, Sheet 2, isa sectional elevation through the center of the machine, the mold-support being shown standing at the lefthand limit of its movement, a finished article inclosed in the right-hand blow-mold under the pressing and blowing member, the press-mold standing closed under the cutter ready to receive its charge of molten glass, and the left-hand blow-mold open. In this figure the cam-track for moving the moldsupport is shown in elevation. Fig. 3, Sheet 3, is a transverse sectional elevation at right angles to that of Fig. 2, showing the pressmold, with its charge of molten glass, in position .under the plunger. Fig. 3, Sheet 3, is a fragmentary sectional elevation of the treadle and its associated parts, showing the treadle elevated. Fig. 4, Sheet 4, is a side elevation of the machine, showing the pressmold under the plunger, as in Fig. 3, and the plunger depressed. Fig. 5, Sheet 5, is ahorizontal section, partly in plan, on the line a a of Fig. 1. Fig. 6, Sheet 6, is a horizontal section, partly in plan, on the line b b of Fig. 2. Fig. 7, Sheet 6, is a plan View of the mold-bed, partly in section, standing in the same position as in Figs. 2 and 6. Fig. 8, Sheet 7, is a transverse vertical section through. one of the finishing-molds and its associated parts on the line 0 0 of Fig. 2. Fig. 9, Sheet 7, is an elevation, partly in section, showing the treadle mechanism and cams for operating the plunger and opening the pressmold. Fig. 10, Sheet 7, is a detail view showing the plunger-operating cam and lever. Fig. 11, Sheet 7, is an enlarged sectional elevation illustrating the means for holding the neck-mold in its elevated or its lowered position. Fig. 12, Sheet 8, is a sectional ele 'ation, partly broken away, on the line (I of Fig. 2, showing the cam and its connected levers for operating the neck-mold. Figs. 13, 14, 15, 16, 17, 18, 19, and 20, Sheet 8, are detail views of the cutters and their connected mechanism, Fig. 16 being a sectional elevation of one of the cutters on the line wof Fig. 15 and Fig. 19 being a sectional view of one of theknives on theline ff of Fig. 18. Figs. 16, 19, and 20 are on an enlarged scale. Fig.

21, Sheet 5, is a plan view showing the cam for closing the press-mold. Fig. 22, Sheet 5, is a section showing the air-valve-operating means on the line g of Fig. looking toward the front of themachine. Fig. 23, Sheet 5, isasection on the line Z: Z of Fig. 22. Fig. 24, Sheet 5, is an enlarged section through the valve. Fig. 25, Sheet 2, is a detached view of the bottom-tilting mechanism.

1 represents the main frame of the machine, which may be of any suitable construction. On the top of the frame are tracks or ways 2 for the mold-support or table 3, the latter being shown as provided with depending flanges 4, the lower edges of which rest upon rollercarriages 5, which run in the ways 2, Figs. 2, 3, 4, 6, and 7. In order to more efl'ectually secure the table against lateral disrflacement, I prefer to provide it also with depending studs 6, carrying rollers which bear against the side walls of a longitudinal opening 7 in the top of the frame, Figs. 3 and 4.

8 represents the press-mold, which in the present machine is mounted substantially centrally of the table, and 9 and 9 respectively represent the two blow1nolds, in this case mounted one on each side of the pressmold 8. Each of the molds is shown as formed of two separate body-sections movable toward and from each other in transverse ways 10 on the table, the mold-sections being fastened to carriages 11, which slide in the ways and are held therein by overhanging plates 11. (See Figs. 2, 3, 7, and 8.)

12 represents a press-frame arranged above the table and molds and supported by brackets or standards 13, rising from the main frame on each side of the table. 14 represents the pressing-plunger, which, as already stated, is in the present machine adapted to also serve as a blowpipe. For that purposel prefer to use such a plunger as is illustrated and described in Letters Patent No. 585,469, dated June 29, 1897, and is herein shown (see Fig. 3) as provided with an interior passage having communication at the top with a source of fluid under pressure and closed at the point of the plunger by a valve 15. The stem 16 of this valve passes upwardly through the passage and is provided at its top with a nut 17. Be-

hold the valve 15 normally closed.

however, fluid underpressure is admitted to the plunger, it easily overcomes the tension of the spring 18 and opens the valve15.

The plunger 14 is carried by a cross-head 19, vertically movable on upright guides or columns 20, rising from the press-frame 12. The plunger is shown as arranged centrally over the main frame and is guided at its lower end in an opening 21 in the press-frame. (See Figs-. 2 and 3.) It' is preferably adjustably secured to the cross-head 19 by any suitable means, and for this purpose I have shown it as provided with an upper screw-threaded shank 22, screwed into a threaded opening in the cross-head and held therein by jam-nuts ends of the main frame. Secured to the camshaft 27, as by a drum '28 or other suitable means, is a continuous cam-track, which I have shown as extending completely around the drum and substantially from end to end thereof. (See Figs. 2,3, and 5.) This camtrack is provided atits opposite ends with short straight portions 29, which are arranged substantially on diametrically opposite sides of the drum and shaft, and substantially midwaybetween these straight end portions and at an angle of about ninety degrees or the distance of a quarter-turn therefrom are arranged two other opposite short straight portions 30. Connecting the. end portions 29 with these intermediate portions 30, so as to form of the whole a single continuous circumferential track, are fouroblique portions 31. Depending from the table, substantially centrally thereof, is a, stud 32, the lower end of which, preferably provided with a roller, engages the cam-track. (See Figs. 2, 3, 5 and 6.) It is thus apparent that in a quarter-revolution of the cam-track the stud 32 on the table will pass from one of the straight portions along one of the oblique portions 31 to the next straight portion, thus causing the table to move one step in its traverse, which is a distance equal to that between the center of one of the blowmolds, and the center of the press-mold. Thus, starting with the table at its left-hand limit, as shown in Fig. 2, the stud 32 will passfrom theeleft-hand straight end portion 29 along the oblique portion 31 on the back of the drum to the next intermediate straight portion 30, thereby carrying the press-mold into position under the plunger and correspondingly moving the two blow-molds. The revolution of the cam-shaft and drum continuing,

the stud 32 will remain in the intermediate straight portion long enough to permit theoperation of the plunger, (and movements of other mechanism to be hereinafter described,)

after which, passing into the next succeeding oblique portion, it will move along to the straight end portion opposite that from which it started, (the press-mold having been first opened and the pressed glass blank left suspended under the plunger by means to be hereinafter described,) thus mo ving-the pressmold onward to the opposite side of the plunger and the left-hand blow-mold of Fig. 2 into position under the plunger, where it is closed about the blank and the blowing operation performed. The machine is then automatically stopped. When it is again started,

the direction of movement of the table is reversed, the stud 32 traversing the cam-track back to its original starting-point, and thus carrying first the press-mold and then the right-hand blow-mold successively into position under the plunger. of the cam-shaft 27 and drum 28, therefore,

the table is moved from its extreme position at one end of the machine, as shown in Fig. 2, to carry the press-mold into position under the plunger, hold it there for a period,

then in the same direction to carry the left 'handblow-mold to the same operating-point and hold it there until the blank has been blown and the press-mold again charged. The movement of the table is then reversed to carry the press-mold again into position under the plunger, hold it there for a period, and then carry the right-hand blow-mold to the operating-point, the press-mold and the left-hand blow-mold being returned to their initial positions.

Any suitable mechanism may be employed for operating the plunger; but I prefer and have illustrated mechanism substantially like that described in Letters Patent No. 6741,37 8, dated May 21, 1901. Referring first to Figs. 3 and 4E, 33 indicates a bent lever, one arm of which, preferably bifurcated, is-pivoted at its end to the stationary cross-piece 26 at the top of the machine, and to the other arm is attached a rod 34, carrying a weight 35, which is By one revolution 2 Ilb preferably adjustable on the rod by means of in length by a turnbuckle 10) with the end of an arm 11. This arm is secured to one end of a sleeve 42, (see Figs. 5 and 10,) loosely mounted upon a counter-shaft43, which is journaled in the endsof the main frame 1 and which bears on the periphery of a cam 45,

shown as formed on the end of the drum 28. The cam 45, as shown in Fig. 10, is made up of two circumferential flanges 46 and camflanges 47, extending from the front end of each circumferential flange inwardly toward the cam-shaft 27. The rear end of each circumferential flange terminates short of the radial cam-flange of the other circumferential flange, so as to leave a space into which the roller and arm 44 can enter. Supposing the cam to rotate from left to right, as indicated by the arrow in Fig. 10, the roller on the end of the arm 44 will ride on the circumferential flange 46 until the rear end of the latter passes the roller. When the latter occurs, the roller and arm 44 will move inwardly, thereby withdrawing support from the weighted lever 33 at the top of the machine. The lever 33 will therefore drop, as shown in Fig. 4, and the plunger cross-head 19 and plunger be forced down by the straightening of the toggle formed by the lever 33 and links 36. The cam 45, continuing to rotate in the direction stated, will cause one of the radial flanges 47 to engage the roller on the end of the arm 44 and force the same outwardly onto the other advancing circumferential flange, thus elevating the arm 44, depressing the arm 41, and through the described connections, Fig. 3, elevating the weighted lever 33 and withdrawing the plunger from the mold.

In the present machine I provide a cutting mechanism on each side of the plunger over the respective initial positions of the pressmold for severing the charge of molten glass from the gathering-iron. Each such cutting mechanism is provided with two cooperating blades.

48 and 48 represent two cutter-frames, one on each side of the plunger. These cutterframes are carried by rockers 49, which extend through openings in the press-frame 12 and are fixed to horizontal pivot-pins 50, journaled in the press-frame, so as to have a slight vertical movement in reverse of each otherthat is, when one cutter-frame is lowered the other is raised, and vice versa. (See Figs. 2, 3, 14, 15, and 18.) Each cutter-frame is preferably adjustably secured to the rockers by means of screw-threaded stems 51, secured to the cutter-frame and passing through openings in the ends of the rockers, to which they are secured by jam-nuts. (See Figs. 14 and 18.) The rocking movement of the cutterframes is so timed that each is lowered into position immediately over the press-mold and remains in this position until the blow-mold containing the finished vessel has passed from under the cutter-frame on the opposite side, so that such opposite cutter-frame may stand clear of the neck of the finished vessel.

52 and 52 represent two shafts (see Figs. 3, 4, 13, and 14) which are journaled parallel with each other between the upper separated sides of the press-frame 12. One of these shafts, as 52, is provided at its outer end with abell-crank lever 53, one arm of which is connected by a link 54 to an arm on the adjacent shaft 52, while the other arm of this bellcrank lever (see Fig. 13) is connecl'ed by a link 56 to one arm of a bell-crank lever 57, pivoted on a bracket on the press-frame 12. The other arm of this bell-crank lever 57 hangs beside the table 3 in the path of two studs or projections 58 on the edge of the latter, (see Figs. 4 and 7,) one at or near each end. \Vhen in the movement of the table 3 either of said projections 58 is brought into engagement with the free end of bell-crank lever 57, the latter is oscillated, and through the described connections the

shafts

52 and 52 are correspondingly oscillated.

The

shafts

52 and 52 each carry on their inner ends spurs 59, and between these spurs projects an arm 60, secured to one of the pivotpins of the rockers of the cutter-frames. (See Figs. 3, 14, and 20.) \Vhen the

shafts

52 and 52 are oscillated in one direction by the projection 58 on one end of the table 3, the spurs 59 will act on the arm 60 to rotate the pivot-pins to lower one of the cutterframes and raise the other, in which position they will remain until the corresponding projection 58 on the other end of the table causes their reverse movement.

Each cutter-frame carries a pair of superposed

blades

61 and 61. movable toward and from each other longitudimtlly of the cutterframe. These blades are caused to move simultaneously and are provided with cooperating notched cutting edges, which are substantially \!-shaped, as shown in Fig. 17. l have found this construction of the blades to be of material advantage, since the cut is made evenly and cleanly, the glass falling properly into the mold without any tendency to throw the end of the gather to one side, as is caused by the dragging action of the pivoted shearlike cutters which have been generally employed in manually cutting off the gather. Immediately above the diamond-shaped opening between the blades is an opening 62 in the cutter-frame, through which the gather falls from the gathering-iron.

The blades are carried by slide-

bars

63 and 63, which slide in grooves or ways on the under side of the cutter-frame. (See Figs. 16 and 19.) The blade 61 is loosely carried by its slide-bar 63 by means of depending headed pins 64, secured to the slide-bar and passing through holes in the blade. 'lhis upper blade 61 is held down yieldingly upon the lower blade 61 by means of leaf-springs 65, located between said upper blade and the cutter-frame and secured to the latter. The simultaneous movement of the two blades in opposite directions toward and from each other maybe accomplished by any suitable means, for instance, as shown by a .rod 66, secured rigidlyto one blade, extending longitudinally in guides at one side of the cutter-frame and loosely connected at its free end to one end of a lever 67, pivoted on the'cutter-frame, the opposite end of said lever 67 being. loosely connected to the slide-bar of the other blade.

For operating the blades to cut off the gather any suitable mechanism may be employed, and I have shown herein such mechanism operated by the gatherer by meansof atreadle 68, Figs. 3, 3, 4, and 5. The treadle 68 is arranged at the front of the main frame and is secured to a rock-shaft 69, Figs. 3 and 5. The shaft 69 is provided with an arm 70, carrying a weight 71, Figs. L and 5, which tends to hold the treadle in elevated position. On the treadle is mounted an upwardly-extending arm 7 2, arranged beneath a weighted bell-crank lever 7 3, pivoted on the front ofthe main frame. with a depending arm 74, pivoted at its upper end to the lever, so as to stand in the path of movement-of the arm 7 2 of the treadle, as shown in Fig. 3. The depending arm 74 is provided with a shoulder 75, by which when swung forwardly and upwardly by the treadlecomposed of two pieces arranged side'by sideand carrying between their lower ends a roller 76 for engagement with the treadle-arm. The weighted arm of the lever 73 is connected by links 7 7 Fig. 1, to the forwardly-projecting arms of two bell-crank levers 78, pivoted on opposite sides of the front supporting-bracket 13 of the press-frame. The other arms of the bell-crank levers 78 are connected to two inwardly-extendingoperating-bars 7 9, suspended by links 80, respectively, from studs 81.011 opposite sides of the press-frame 12. The inner end of each of the operating-bars 79 is-provided with a vertically-elongated slot or eye 82,flying adjacent to the rod 66 of the adjacent cutter-frame. Secured to each rod 66 is alaterally-projecting finger 83. (See Fig. 18.) Whenone of the cutter-frames is down in operative position, the finger 83 ofv rod 66 and so operate the blades of the cutter.

When either cutter-frame is elevated out of its operative position, the finger83 of itsrod 66 is withdrawn from the slot 82, as shown at the left-hand side of Fig. 18, and conse- This lever 73 is provided .adapted to roll vertically thereon.

ed arm of lever 73 drops, thereby openingthe knives. When the treadle i's'rel'eased, its arm 7 2 will swing back and pass the depending pivoted arm 7 4:, which will then drop back into place. A cushion 8 1, of rawhide or like material, is preferably mounted on the front of the main frame (see Fig. 3) to deaden theimpact of the inner arm of lever 73.

To cooperate with the press-mold and form the neck of the article as well as to support the pressed blank when the press-mold is opened and until the blowing has been accomplished, I provide a neck-mold 85, which in the present machine is supported independently of both the plunger and the table, be-

ing opened and closed at the operating-point immediately under the plunger. This neckmold comprises two sections, which I have shown as slidably mounted on the under side of a frame 86 and movable toward and from each other. The frame 86 is providedwith a central opening containing the plunger-ring 87, which is of any suitable construction and serves to complete'the mold between the neckmold and the plunger, as shown in Figs. 2 and 3.

7 The frame 86 is given aslight vertical move ment. into and out of oper'ative position and for that purpose, as well as for opening and closing the neck-mold, I preferably make use of mechanism arranged and operating as follows: 88 represents levers arranged at oppo site ends of the frame 86 and each pivoted between a pair of posts 89, mounted on said frame atits opposite ends, Figs. 3 and 11. The inner depending arms of thelevers 88 extend down through openings in the frame and are loosely connected to the neck-mold sectionsas by extending into openings in the latter. The other arm of each lever 88 projectsoutwardly between two plates90, Fig. 11, se cured to the adjacent pivot-posts 89.andextending upwardly between the sides of the press-frame 12. Each of the plates 90 is provided with a roller, which bears against the adjacent inner face of the press-frame and is per ends'of the plates'90 are reduced, so as to form spring-shanks 91, and are connected together. The action of the spring-shanks is to hold the plates 90 -outwardly and cause their rollers to bear with considerable friction against the inner faces of the sides of the press-frame, soas to hold the neck-mold frame 86 in the position to which it is moved. The pressure of the spring-shanks 91 is preferably made adjustable by means of a block 92 located between the converging shanks and adjustable by a set-screw 93. The neckmold frame 86 is provided with vertical guiderods 94, extending upwardly through guidebearings on the walls of the press-frame. When the outer ends of the levers 88 are moved downwardly, they first act to slide the sections of the neck-mold 85 together, and then by their continued downward movement cause the neck-mold frame 86 to movebodily downward into operative position. hen the levers 88 are moved upwardly, they act to first separate the neck-mold sections and then i move the neck-mold frame bodily upward, the latter being then held in elevated position by means of the friction devices described.

The outer ends of thelevers 88 are connected by links 95 (preferably made adjustable in length by turnbuckles, so as to make the neck-mold adjustable to the height of the article to be made) to arms 96 of the horizontal rock-shafts 97, (see Fig. 3,) mounted on opposite sides of the main frame. On the end face of the drum 28, opposite to that shown in Figs. 9 and 10, (see Fig. 12,) is a cam-track tions 99.

made up of diametrically opposite salient cam portions 98, connected'by concentric por- To the rock-shafts 97, adjacent to this end of the drum, are secured the arms 100,-connected by links 101 to levers 102, arranged beside the cam-track on opposite sides of its center and pivoted at their lower ends to studs on the end wall of the main frame, Figs. 2 and 12. Each of thelevers 102 is providedwvith a roller 103, engaging the camtrack.

When the rotation of the drum 28 causes 4 the rollers 103 to move inwardly into the portions 99 of the cam-track, the levers 102 are drawn toward one another, thereby rocking the shafts 97 and drawing the levers 88 downwardly, thereby first closing the neck-mold sections and then moving the neck-mold frame and the neck-mold bodily downward onto the press-mold.

. As has been hereinbefore stated, I employ the neck-mold to support the pressed blank after the press-mold has been opened and until the blowing has been accomplished. The rollers 103 Will then enter the portions 98 of the cam-track, thereby moving the levers 102 away from each other and through the described connections first open the neck-mold and then lift it bodily from the blow-mold. The machine is then automatically stopped by mechanismto be hereinafter described.

Any suitable means may be employed for opening the press mold to disengage the pressed blank, and I have shown in the accompanying drawings one arrangement of mechanism Well adapted for that purpose.

'On the drum 28 at diametrically opposite points are arranged two projections 101, and in the path of said projections and on opposite sides of the drum are the ends of two levers 105, pivoted on brackets on the main frame, the upper endsof which normally restagainst the sides of the main frame. (See Fig. 3.) Journalcd in suitable bearings depending from the ends of the table 3 and at opposite sides thereof are horizontal shafts 106, and loosely mounted on said shafts on opposite sides of the press-mold are the bell-crank levers 107, the lower arms 108 of which hang doumwardly. The other inwardly-extending arms 109 of these levers are connected by links 110, which .extend upwardly through suitable slots in the table, with rock-arms 111 loosely mounted upon horizontal shafts 112, journaled at the front and rear ends of the table in upwardlyprojecting bearing-brackets. The rock-arn'is 111 project toward the adjacent press-mold sections and are respectively connected to such opposite sections by links 118. The links 113 and rock arms 111 constitute toggles and serve when extended to firmly hold the pressmold sections in closed relation. \Vhen the table 3 isat the center of its range of movement, with the press-mold under the plunger. the ends of depending arms 108 of lovers 107 will lie respectively inside and in the line of movement of the upper ends of the levers 105. Immediately after the plunger has been retracted from the press-mold the opposite projections 101 on the drum28 will strike the lower ends of levers 105, throwing the lower ends of said levers outwardly and their upper ends inwardly against the depending arms 108 of levers 107, and thereby through the described connections draw the press-mold sections apart to disengage the pressed blank. The levers 105 return by gravity to their normal position, and with the next movement of the table the press-mold is again closed by mechanism preferably constructed and operated as follows: 11 1, Figs. 3 and 21, represents a pair of camplates suitably secured to the opposite sides of the main frame below the table and longitudinally thereof. Each camplate is of concave form, being curved in an arc concentric with the of the adjacent lever 107, and is provided with a central slot 115, extending from the outer toward the inner side thereof, in which works the upper end of the adjacent lever 105. The upper curved face of each cam-plate is provided with a curved camgroove 116, the ends of which coincide with the limits of movement of the press-mold and the levers 107, and a straight groove 117 connects the ends of the curved groove. The end of the depending arm 108 of the adjacent bell-crank lever 107, which is preferably provided with an antifriction-roller, rests in said grooves and travels therein with the movement of the table. hen the press-mold is in position under the plunger, the end of de- IIO ' 116. Immediately after the presssmold has been thus opened ,the movement of the table commences, and the ends of the arms 108 arecaused to move in the curved grooves116 gradually back to the ends of the straight grooves, thereby effecting the closure of the press-mold when the table has again come to a stop with the press-mold under one of the cutters. Then when themovement of the table is reversed to bring the press-mold again under the plunger the ends of thearms 108 travel in the straight grooves 117 until the press-mold is in position and they again rest in the slots immediately in front of the ends of levers105. I

For closing the blow-mold about the pressed blank any suitable mechanism arranged tobe operated at the proper time may be employed,-

that which I believeto be best adapted to thebevel-pinions 119 at the ends of said transverse shafts meshing with bevel-pinions 120, secured to said longitudinal shafts, Fig. 6. The lower longitudinal shafts 106 are respectively connected by rock-arms 121 and links 122with rock-arms upon the upper longitudinal shafts 112. Each of the shafts 112 is provided with two rock-arms 123 and 124:, the armsel23 on each shaft being adjacent and connected to the opposite sectionsof the blowmold 9, and the arms 12 1 on each shaft being adjacent and connected to the opposite sections of the blow-mold 9*, such connections being made by links 125, so that, as in the case of the press-mold, said rock-arms and links form toggles for firmly closing the molds. (SeeFigs. 7 and 8.) The rock-

arms

123 and 124 on each shaft 112 are arranged at angles to each other, so that when the shafts 112 are rocked to close one of the blow-molds the other blow-mold will be opened by the same movement-that is, the blow-molds are opened and closed in reverse.

Eachof the transverse shafts-118 and 118 is provided with a depending tappet-arm 126,

and at the opposite ends of the machine are bent levers 127, pivoted to the'main frame, the

upper ends of whiclnpreferably provided with a roller, lie in line with the respective tappetarms 126. (See Figs. 1 and 2.) The opposite ends of said levers127 arealso provided with rollers which rest upon cam-disks 128, mounted on opposite ends of the shaft 27. Each of these disks has a cam projection adapted to pass under and oscillate its lever 127 when the table reaches the limit of its travel in that direction, thereby causing the upper end of said lever 127 to engage and tip its tappet-arm 126,

and thus rock the transverse shaft to which i the same is secured. This movement operates, through the described connections, to rock the

longitudinal shafts

106 and 112, and thereby open one of the blow-molds and close the other, the arrangement being such that the blowmold at the outer end of the machine is opened and the inner mold, which then stands at the center of the machine, is closed about the blank under the plunger.

Each of the blow-molds is preferably provided with a tilting bottom 129, Figs. 2 and 25, pivoted. in anopening in the table. To the forward or outer side of'the bottom are pivoted two hook-shaped links 130, extending rearwardly at opposite sides of the tappet-arm 126. The inner ends of these links are suitably supported, as by chains 131; When the end of lever 127 has tilted the tappe't-arm 126, it continues its inward movement far enough to engage and pull upon the hook-shaped links 130, thereby operating to tilt the bottom 129 of the open blow-mold and eject the finished article.

As has heretofore been stated, in the present -machine the combined plunger and blowpipe is suitablyconnected with a supply ofcompressed air. For that purpose I provide a pipe 132, connected at one end to the source of supply and at the other end, by means of a flexible hose or pipe 133, with a suitable passagein the movable cross-head 19. The pipe 132 is provided with acock or valve 13 1, of any suitable construction, Figs. 3, 5, and 23, for admitting and shutting off the air, such valve being operated at the proper times by mechanism preferably constructed and arranged as follows: The valve 134 is provided with opposite actuating-

arms

135 and 136. Adjacent to the valve is a -shaft 137, rotated by suitable means, such as by a chain 138, connecting a sprocket-wheel 139 on shaft 137 with a sprocket-whee-l-140 on the cam-shaft 27, said sprocket-wheels being of equal size, so that the shaft 137 may rotate at the-same speed as the cam-shaft. The shaft 137 is provided with'two trip-arms arranged on opposite sides of the valve-stem and at right angles to each other, (see Fig. 23,) so that with each quarter-revolution of the shaft 137 one of its trip-arms will strike one ofthe valve-actuating arms and move the valve in one direction and then wipe past the valve-actuatingarm. (See Fig. 22.)

, Such movement throws the other valve-actuat- 1 144, mounted on the main frame.

ing arm in the path of the other trip-arm, so as to be engaged and moved by the latter to return the valve to its former position. It will thus be seen that with each complete revolution of the cam-shaft 27 the valve is opened and closed twice.

The drivingmechanism for the present machine is preferably constructed and arranged as follows: 141 represents a main drivingshaft (see Figs. 3, 4, and 5) arranged parallel with the cam-shaft 27 and counter-shaft 43 at the rear of the machine and provided with a driving-pulley 142. The shaft 141 is mounted eceentrically in a cylindrical bearing-block 143, the latter being journaled' in a bearing (See Figs. 5 and 9.) By a small rotative movement of the block 143 the shaft 141 is moved toward or away from the counter-shaft 43. The shaft 141 carries a friction-wheel 145, adapted to make contact with a friction-wheel 146 on the counter-shaft 43 when the shaft 141.is moved toward said counter-shaft. The block 143 is provided with an arm 147. preferably integral therewith, the end of which is pivotally secured to the end of a rod 148. The opposite end of the rod 148 is pivotally secured to an arm 149 on the treadle-shaft 69. hen the treadle is depressed by the operator, the rod 148 is drawn forward, and thereby causes a slight rotative movement of the block 143 in its bearing, which serves to throw the shaft 141 toward the counter-shaft 43, bringing the friction-

wheels

145 and 146 into contact with each other and revolving the counter-shaft. The counter-shaft carries on its opposite end a pinion 150, meshing with a pinion 151 on the. cam-shaft 27, whereby the latter is driven. The driving-shaft is supported at its other end in a bearing 142, Fig. 5, which afl'ords sutlicient play to permit the movement above de scribed.

152, Figs. 5 and 9, represents a disk secured to the cam-shaft 27 adjacent to the rod 148 and provided with two diametrically opposite notches 153 in its periphery. 154 representsa dog pivotally attached to the rod 148, the free end of which, preferably provided with a roller, is adapted to enter either of the notches 153. The dog is held yieldingly against the periphery of the disk 152 by means of a spring 155, arranged between the dog and the rod 148. When the machine has been set in motion by the depression of the treadle, as above described, the weight 71 tends to drop to elevate the treadle, and thus effect the separation of the friction-

wheels

145 and 146, but cannot do so as long as the end of the dog 154 is riding on the unbroken periphery of the disk 152. When, however, .one of the notches 153 on the periphery of the disk comes opposite the end of the dog, the latter enters the notch, permitting the weight to drop, the treadle to rise, and the driving-shaft 141 to be thereby retracted, thus automatically stopping the machine. \Vhen the treadle is again depressed, the rod 148 is drawn 'lorwardly,

whereby the end of the dog 154 is moved out of the notch 153, the friction-

wheels

145 and 146 are brought in to contact, and the lnachine again set in motion, which continues until the. disk 152 has made another half-turn, bringing the other notch 153 opposite the free end of the dog.

As has already appeared from the description hereinbefore given, the plunger of the present machine is depressed by gravity, and the extent of its downward stroke is regulated by the amount of glass in the press-mold. In the use of such pressing mechanism it is practicable and of advantage to indicate to the operator the amount of glass which has been dropped into the press-mold in each case, so as to guide him in charging the press-mold for the next article. I have illustrated in Figs. 1, 3, and 4 a suitable gage mechanism and indicator for this purpose. 156 represents a dialplate fixed to a stationary part of the machine, such as the cross-piece 26, and provided with a scale or graduation arranged in an are on its face. 157 represents a. pointer pivoted to the dial-plate concentrically with the scale or graduation. This pointer normally held raised by a spring 158 of any suitable construction. A link 159 is pivoted at its upper end to the pointer and extends downwardly adjacent to the movable crosshead 19 of the plunger, where it terminates in a hook 160, extending beneath and in the path of a projection 161 on the said movable cross-head. When the plunger and crosshead descend, the projection 161 engages the hook 160, pulling the link and pointer downwardly during the latter portion of such downward movement, and the pointer therefore indicates on the graduated dial the extent of the downward movement of the plunger in each case.

The operation of the complete machine hereinbefore shown and described is as follows: Assuming the table to be standing at the lefthand limit of its movement, as shown in Fig. 2, with the press-mold closed ben ath the lefthand cutter, the left-hand blow-mold open, a finished article in the righthand blow-mold still under the plunger, the neck-mold open and elevated, and the machine at rest with the treadle in its elevated position, the gatherer drops a charge of molten glass through the opening in the cutter-fran'ie into the pressmold and depresses thetrcadle with his foot. As the treadle descends its arm 72 strikes the depending arm 74 of lever 73, elevating the latter and through the described conne ,-.tions moving the blades of the cutter inwardly to cut off the gather. The weight on the lever 73 immediately thereafter serves to return the latter and the cutter-blades to their nor mal position. The downward movement of the treadle being continued, the shaft 69 is rocked and the rod 148-drawn forwardly, thus disengaging the .dog 154 from the notch in the disk 152 and throwing the friction-wheel on driving-shaft 141 into contact with the friction-wheel 146 on counter-shaft: 43. Motion is then transmitted to the. counter-shaft and therefrom by the pinions and 151 to traversing the intermediate straight track 30.

As soon as the press-mold has arrived inposition under the plunger the neck-mold cam, Fig. 12, draws the levers 102 toward each other, andthese levers through the described connections operate to first close the neckmold sections and then lower the same bodily upon the press-mold. Just asthis has been accomplished the rear end of one of the circumferential portions 46 of the cam 45, Fig. 10, passes the end of the arm 44, and thereby permits the weighted arm of lever 33 to drop, whereby the plunger is impelled into the glass in the press mold and the blank pressed. After a sufficient dwell one of the radial portions 47 ofcam 45 engages the end of arm 44, forcing the same outwardly upon the other circumferential flange, and thereby elevating the weighted arm and the plunger. The drum 28 continuing to revolve and the end of the intermediate straight portion 30 of the camtrack having almost reached the stud 32, the opposite projections 104 on the drum, Fig. 3, engage the lower ends of levers105, rocking the bell-crank levers 107 and through the described connections drawing the press-mold sections apart, the pressed blank being left suspended from the neck-mold under the plunger and in the path of the blow-mold, which is now advanced. The end of the intermediate straight portion of the cam-track has now passed the stud 32, and-the revolution of the drum 28 still continuing the said stud traverses the next oblique portion until it reaches reached the right-hand limit of its movement,

and the right-hand cam-disk 128 operates its lever 127 to throwthe upper end of the same inwardly against the tappet-arm,126 of transverse shaft 118;

The consequent oscillation of shaft 118 operates through the described connections to oscillate the upper longitudinal shafts 112, so as to close the left-hand blow-mold about the pressed blank under the plunger and to open the right hand blowmold at the end of the machine to discharge its finished article, the pivoted bottom of said mold being tilted for that purpose, as already described.- As soon as the left-hand blow-mold. has been closed about the blank one of the triparms on the shaft 137 operates one of the actuand air is forced through the supply pipe,fleXible hose, cross-head, and plunger into the suspended blank and the body of the latter blown out to the form defined by the inner walls of the blow-mold. The portions 98 of the neck-mold cam, Fig. 12, then engage the rollers on the levers 102 to draw the same apart, whereby the neck-mold sections are first opened and then lifted bodily from off the neck-mold. One of the notches 153 in the periphery of disk 152 has now come oppositethe end of dog 154 and the weight 71 has operated to throw the dog into the notch, thereby automatically stopping the machine with the air being'still blown through the plunger into the finished article in the blow-mold. The passage of the air into the article is continued until the machine is started again, since I have found this to be of advantage in propprojection 58 on its edge at its left-hand end had engaged the depending arm of bell-crank lever 57 and through the described connections with the rock-

shafts

52 and 52 had oscillated the latter to raise the left-hand cutter-frame and to simultaneously lower the right-hand cutter-frame to its operative position immediately over the press-mold. The machine having now stopped, the gatherer drops a charge of molten glass into the press-mold standing at the right of the plunger and then depresses the treadle to first operate the right-hand cutter and then again starts the machine. As the machine starts the air-valve is immediately closed and the table is then moved in the reverse direction to carry first the press-mold and then the right-hand blow-mold into position under the plunger, the same series of operations being performed as before.

As stated at the outset of this specification, I have herein illustrated anddescribed a com plete machine in the form which'l regard as the preferable embodiment of my invention in all its features. It is, however, obvious that the specific mechanism of this machine may be altered in many respects without materially changing its general organization and operation, and it is also obvious that certain features of my invention may beemployed in machines of other types.
