The referred embodiment of our invention is lllustrated in conjunction with a 1'0- tary type bottle blowing machine 15 including partible finishing molds 16 each comprising a pair of mold sections 17 pivoted to a vertical hinge pin 18 and movable toward and from each other at regular time intervals. A bottom plate 19 cooperates with each finishing mold in final sha ing of the articles of glassware and as will apparent presently may su port the articles for ashort er the finishing mold opens so that a combined takeout and transfer device may be positively engaged with the upper portions of said articles.

glassware annealing leer 20 may he arranged with blowing machine 15. This leer includes a leer conveyor ill extending lengthwise of the leer tunnel to convey glassware through the latter. Transversely aligned openings 22 are formed in the side walls of the leer, permitting movement of the transfer devices over the leer conveyor. I

Means to remove the finished articles of. glassware from the finishing molds 16 and transfer ,them to the leer conveyor 21 includes a series of takeout and transfer devices whose movements are synchronized with those of the finishing molds so that when a finishing mold reachesthe ware eject-. ing station one of the takeout and transfer devices immediately moves into position to its receiving end adjacent the.

engage the neck of an article while the latter is su ported on the bottom plate. These trans er devices (Fig. 1) are supported on an endless chain 23 running over sprockets 24 and through the openings 22 in the side walls of the leer20. This chain 23 is subject to continuous movement in order to bring the takeout and transfer devices in succession to positions for removing glass articles from the finishing molds and placing them in rows extending across the leer conveyor 21.

Each takeout and transfer device first grips the upper end or neck of a bottle while the latter is supported on a finishing'mold p and neck gr bottom plate 19 and a moment later replaces said bottom plate with a su porting arm 28 which prevents the bottle om sagglng or becomin otherwise distorted. Each of these devices Figs. 3 to 10 inclusive) comprises a horizontal base 25 carrying at one end an extensible upright 26 or standard, the latter connected through an arm 27 (Fig. 4) to the sprocket chain 23. The upright 26 includes two bars bolted together and capable of lengthwise adjustment to vary the spaced relation between a bottom supporting arm 28 ifping device 29 or jaws atthe upper end 0 the upright.

The neck engaging device 29 (Figs. 3, 4, 9, 11 and 12) mounted upon the upper end of the upright 26 includes a stationary jaw 30 and movable jaw 31, the latter pivoted to a, horizontal hinge pin 32st the outer end of a.

horizontal arm 33' which is formed on the upper section of the upright. The movable jaw 31 islformed with a notch 34 in which the" neck of the bottle B is arranged during the takeout and transfer operation. This movable jaw 31 is normally held in a plane above the upper-ends of the articles of glass were as shown in Figs. 11 and 12. This positioning of the jaw 31 is obtained by an expansion spring 35 which encircles a push rod 36 extendin through a horizontal opening in the uprigit and connected through a link 37 to an arm 38 formed on the jaw. The other end of this push rod 36 carries a cam roll 39 which engages a cam 40 (Figs. 4 and 1) during movement between the ware ejecting station E andthe point at which the devices enter the annealing leer.

The bottom supporting arm 28 (Figs. 3, 4, and 6 to 10 inclusive) which supportingly contacts with the bottoms of the articles, is arranged in a horizontal guideway in the base 25, said am being secured to a slide block 46 in a slideway 47. The slide block 46 is adapted for reciprocation in the slideway 47 in order to alternately project and retract the bottom supporting arm 28. A pair of coil springs 48 (Fi 6 and 10) may beem loyed to movethesli eblocktowardthe uprig t 26 (Fig. 7) and thereby position the arm 28 beneath the bottle or similar-article I of glassware. Movement of the block in the formed opposite direction is obtained by a cam roll 49 .carried by the slide block 46 and adapted to be engaged by a trip device at regular time intervals as will be described presently. The slide block 46 and arm 28 may be locked in their retracted position. This is obtained by arranging a spring pressed detent 50 in a recess formed in the lower side of the slide block 46 (Figs. 6, 7 and 8). When the slide block is fully retracted (Fig. 6) the detent 50 is vertically aligned with and positioned in an upwardl opening recess 51 in the base 25 so that acc1- dental relative movement between the arm and base is avoided. Release of the slide block and arm for movement under influence of the coil springs 48 is obtained b upward movement of a push rod 52 whose lbwer end projects below the base 25 and is adapted to engage a stationary cam 53 (Figs. 1, 2, 7 and 8) arranged a short distance beyond the station E at which the jaws engage the articles being removed from the machine.

The takeout and transfer devices and supporting chain 23 therefor are held against sagging or tilting by upper and lower rails 55 and 56 respectively. A grooved roller 57 carried by the upright 26 rides upon the upper rail 55 and prevents downward movement or sagging of the chain and devices carried thereby. A grooved roller 58 carried by the base 25 rides on the rail 56 and prevents tilting of the takeout and transfer devices. Thus these devices are securely held against assuming abnormal positions which might result in distortion or dropping of the articles of glassware removed from the forming machine.

The takeout and transfer devices move in successlon transversely of the annealing leer through the opening 22 (Figs. 1, 11 and 12) preparatory to placmg the articles of glassware upri ht upon and in transverse rows across the eer conveyor 21. Just before one of the transfer devices enters the leer, the ]awv 31 (Figs. 3, ll'and 12) releases the neck portion of the bottle or other article being transferred so that the latter is entirelv supported upon the arm 28 as shown in Figs. 7 and 11. This operation is due to termination of the cam 40 at a point adjacent the entrance opening. 22. Immediately after the transfer device moves beyond the end of the 'cam 40, the spring 35 swings the j aw 31 to the position shown in Figs. 11 and 12.

The transfer devices are actuated one at a time while moving over the leer conveyor 21 to set the articles upright and in s aced relation upon the leer conveyor. This is obtained by removing the supporting plate 28 from its position beneath the article of glassware. The structureby which this is accom lished comprises a cam 60 arranged within t e leer tunnel and adapted to be red rocated transversely thereof. This cam igs. 1, 11 and 12) engages the cam rolls 49 one at a time and accuses thereby moves the bottom su' porting Iplate Modificationsmayberesorted to within the or arm 28 from the position shown in 1g. 7 spirit and scope of the appended claims.

to that shown in Fig. 6. In the latter position the detent 50 automatically locks the arm against premature outward movement.

The cam (Figs. 1, 11 and12) is mounted on the outer.end of an arm 61 suitably con'- nected to a threaded shaft 62, the latter 10H!- naled in bearings 63 at opposite sides of the leer and continuously rotated by means (not shown) operating through a sprocket chain 64 and s rocket 65. Movement of the forming mac ine, takeout and transfer devices, and the cam 60 are so synchronized that said devices arrive at the ware ejecting station at proper time intervals and the cam 60 effects release of the articles from said vdevices in a fashion to arrange the articles spaced apart and in transverse rows across the conve or 21.

In operation, the takeout and trans er devices are continuously moved .in the direc tion indicated by the arrows in Fig. 1 so that they are brought in succession to the were ejecting station E. When one of the devices arrives at the ware ejecting station, a finishing mold 16 opens leaving an article of glassware supported on the bottom plate 19. The cam 40 now en the cam roll 39 and thereby causes movement of the jaw 31 (Figs. 3 and 9) into engagement with the neck 0 the bottle or other article of glassware.- This neck gripping o ration may take place prior to openin o the finishing mold, if, desired. Continued movement of the forming machine 15 causes removal of the bottom plate 19 from beneath the bottle B and leaves the latter suspended from the neck 'pping device 29. Almost immediately the ttom suspporting arm sition own in Fi 4 wherein it contacts with the bottom of e bottle. Such projection of this arm 28 is obtained bi upward movement of the detent 50 who permits the coil spring 48 to project said am 28 as shown in Figs. 4 and 7. Thus the bottle is held against sagging. Just before the device enters the leer, the movable jaw 81 is swung upwardly to the position shown in Figs. 11 and 12 so that the bottle is free to move in the direction of travel of and with the leer conveyor 21. At a predetermined point in its travel acres the leer, the bottom supporting plate 28 is retracted so that abottle stands upright upon the leer conveyor 21. As previously pointed out, retraction of the arm or plate 28 is obtained by means of the camBO which moves back and forth across the leer and during movement in one direction successively engages the cam rolls 49 on the takeout and transfer devices and thereby causes positioning of the arms as shown in Figs. 6 and 12. In this manner the articles of glassware are placed upright and in transverse rows upon the leer conveyor.
