BOTTLE-CROWN REMOVEB.

- Application fled January 3, 1927. Serial no. 158,604

and which are held by an annular flange tha is crimped into locking engagement with a shoulder on the outer si e of the bottle neck.

The internal pressure against the under side of the crown makes it morediflicult to remove because that pressure keeps the crimped-in locking flange of the crown close around the locking shoulder and when the prying ofi' operation takes place it is necessary to exert quite an u ward pull to strip the crown from the sho der and frequently this pull is .siificient to break the neck of the bottle.

I have noted during the crown removal operation, that-after the crown has been disturbed sufficiently to vent the internal pressure the balance of the removal operation is exceedingly easy and I have therefore provided a crown remover which will first operate to e-'ect a vent for the internal pressure and wi then operate to remove the crown.

- With these, and other ob'ects in view, the invention is illustrated in e accompanying drawing, wherein,

Fi 1 shows the-improved crown-remover insi eview. z

Fig. 2 illustrates the same'in front elevation.

Fi 3 shows the improved remover in position againstthe crown in readiness for the preliminary operation of venting the crown.

Fig. 4 illustrates the position of the remover with respect to the crown while puncturing the latter to vent the mternal pressure and v larged scale through a, portion of the crown to illustrate the vent Opening made in the latter just bottle-neck.

prior to its removal from the Referring to the drawing the numeral 7 designates the, hand-hold or bodyart of the remover which may be of any orm or eliabilit of breaking theneck during the prying o shape desired, but which in the present instance is formed from a flat blank of metal sufliciently stiff to meet the strains to which it will be subjected.

In the resent instance one end. of the body-part has a projection, 8 whose opposite edges are-beveled, as at 9, to produce a screwration, 10 is also provided in the same end in order that the tool may be hung on a hook or nail. These features, however, are not essential, and in fact, are immaterial tothe present invention.

At the forward end, the remover tool has.

ing-arm 13, to project over the top ofacrown and this arm has a bottom ed e 14, in a horizontal plane above the hook 1 which edge 14, forms a fulcrum point by seating on top of the crown I during the removal operation.

At the bearing or fulcrum edge 14, I provide a dependin pin, prong or piercing projection 15, W-lllCh latter may be of a variety of shapes, but I have found in practice that if I form this rojection with a straight rear edge 16, w ich preferably inclines forwardly as it extendsdownwardly, and a beveled and reversely-inclined" forward cutting-edge 17, that Igain advantages ,in operation which will presently be e lained.

It is also to be noted that the width of the depending projection 15, immediatel beneath the bearing or fulcrum edge 14 is narrower at 18 than at a point below it, and this alsois done with deliberation because of an advantage gained thereby, as will also presently be pointed out.

In Figs. 3 and 4 of the drawing I show a bottle-neck-19, with a conventional crown 20 thereon 'and in Fig. 5, I show a ortion ofthe under side thereof as is. usually provided in these metal crowns. Fig. 5 shows a sectional detail on an en-' In; the operation of the improved reriver tool, and an'opening or perfoon. its under-side a recessll with a formover tool I first engage the hook 12 beneath the crimped or corrugated flange 22 of the metal crown and then swing the forward 'end of the tool down over the topof the crown to present the point of the cutting edge of the projection15, to the to of-the crown, as shown in Fig. 3 of the rawing.

Then, as the body-part 7 of the tool is raised the tool will rock on the hook 12, and the cutting edge 17 of the projection 15 will pierce the top of the crown and cut its way through the crown and also through the sealing disk 21. While the downward motion of the projection 15 throu h the crown is takin place, the strai t edge 16 at the rear side of the lug, whic edge ,is blunt, keeps the tool drawn forward and holds the hook 12, under the flange 22 of the crown,the cutting being accomplished by the forward inclined cutting edge 17 of the piercing projection.

As the rocking of the tool is continued the narrow portion 18 of the piercing projection will occupy the longer slit 23 that has been made through the crown and its sealing disk by the broader part of the lug that has passed to the underside of the crown and thus leave suflicient free opening in the crown and seal about the projection for the escape of the gas in the bottle, thereby relieving the crown of the internal pressure wardly-inclined cutting-edge in front of the said rear blunt-edge whereby the straight blunt edge will draw the tool forward and keep the hook engaged with the crownflange as the front inclined cuttingedge of the projection enters the crown.

In testimony whereof I afiix my signature JOSEPH H. MILLER.
