ROBERT F. JUNGNIGKEL, OF MINNEAPQLIS, MINNESOTA.

MACHINE FOR APPLYING CROWNS T0 BOTTLES.

Application filed. November 28, 1913.

To all whom it may concern Be it known that 1, ROBERT F. JUNG- NICKEL, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Machines for Applying Crowns to Bottles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to machines for applying metallic stoppers or so-called crowns to bottles, and has for its object to provide an extremely simple and highly efficient device for accurately positioning the crowns in the operation of applying the same to the bottles. I

Particularly, this invention relates to automatic crown machines of the kind wherein the metallic bottle crowns are automatically fed from a hopper through a supply chute, to so-called crowning heads that are mounted on a rotary bottle carrying cage.

My invention provides a positioning arm or spring which serves to accurately position the bottle crowns in alinement with clenching recesses provided in the crowning heads for the reception of the crowns and necks of the bottles, in the act of applying the crowns to the bottles.

The invention is illustrated in the accompanying drawings, wherein like characters indicate like parts throughout the several views.

Referring to the drawings, Figure 1 is a view in side elevation with some parts broken away and with some parts sectioned, showing portions of an automatic crown machine of the type above referred to, having my invention applied thereto; Fig. 2 is a diagrammatic plan view with some parts broken away showing parts of the machine found in the vicinity of the line marked 00 00 on Fig. 1; Fig. 3 is a section taken approximately on the line x m on Fig. 1 and showing the parts on an enlarged scale; and Fig. 4: is a section taken on the line w 00 on Fig. 3.

Of the parts of the automatic crowning machine, it is only desirable for the purposes of this case to briefly note the following elements, to-wit, the numeral 1 indicates a fixed upright column around which a heavy column sleeve 2 is arranged to rotate, with its lower end list above a fixed cam plate 3 hav Specification of Letters Patent.

ing raised plunger actuating cam surfaces 4. The sleeve 2 carries plunger guiding disks 5 and 6 and an upper disk 7. This upper disk 7 carries upright circumferentially spaced crowning heads 8 having axial bores that extend downward through the said disk 7. The disk 7 is provided with a peripheral groove that leads to the bores of the several crowning heads 8. Within the crowning heads are clenching devices, not shown.

The crowns indicated by the character y are placed in the hopper secured on the upper end of the column 1. In Fig. 1, the base 9 only of this hopper is shown. The crowns are fed from the hopper through a crown chute 10, the lower end of which terminates within the peripheral channel 7 of the disk 7 so that under rotation of the said disk, the crowns will be delivered one after another into the lower extremities 11 of the bores of the crowning heads. As shown in Figs. 2, 3 and 4, these lower extremities 11 of the bores of the crowning heads 8, open into the said peripheral channel 7*.

The sleeve 2 and disks 5, 6 and 7 consti tute what in the trade has been designated as the cage of the machine. The heads 5 and 6 have vertically movable plungers 12 axially alined with the crowning heads 8 and adapted to support the bottles 2 on their upper ends. The lower ends of the said plungers rest on the cam plate 3, and, at the proper time, are passed over the cam 4: and the said cam thus operated in succession to raise the bottles and force the necks against the alined crown and up into the overlying crowning head 8.

This much of the construction and operation of the machine is well known to all persons familiar with the operation of bottling machine of the so-called automatic crowning machine type. In the operation of these machines, it was found that bottles will be frequently broken simply because the crowns g which were forced into the open lower ends 11 of the crowning heads, would jar or rattle slightly out of axial alinement therewith. This I prevent by the use of a spring arm, against which the outer edges of the crowns will be pressed, at the time the bottle is forced upward into the crowning head. This spring arm lightly presses the crown into the open lower end 11 of the crowning head at such time and keeps the same in true axial alinement both with the bottle and With the crowning head. Preferably, this spring positioning arm is in the form of a leaf spring 13 secured to a metal bar 14, which, in turn, is secured to a post. 15 on a fixed table 16 that surrounds the disk 6.

As already indicated, the improved crown alining device prevents breaking of bottles. In running machines of this kind, the fingers of a good many operators have been crushed or cut off in an attempt to properly ahne the crowns at the. time the bottles are moved upward to force the crowns into the crowning heads. My automatic ali'ni'rig device, as is obvious, entirely removes the cause for such accidents.

heefiicien'v of cct wn p s tio ng evice described has been demonstrated, in practice, and hasbeetli mll dthat, by the use ereof, b ea'k 9 b s dug a ad annement bit the crowns, is done away'with.

What I claim is: j

In a mach ne or app y g crew to bottles, the combination with a rotary caria ertic ly n bve bet l fsl pi or s p u s r an l ip ra n cr wn n hea s; n s id ar ia e Sai r wn n 'h a s being providedwithmeans for rebiving the crowns of a yielding crown-positioning arm bottles into said crowning heads, a crown delivery chute for delivering crowns to said crowningv heads in succession, and a relatively fixed spring arm arranged to engage the projecting edges of the crowns in succession and at the same time that the corresponding plungers are raised to force the necks of the bottles against said crowns and" into said crowning heads.

In testlmony whereof I affix my signature in presence of two w tnesses.
