MACHINE FOR REBENDING CROWN CAPS OR SEALS FOR BOTTLES.

SPECIFICATION 'forming part of Letters Patent No. 631,785, dated August 29, 1899.

Application tiled December Z0, 1898. Serial No. 699,825. (No model.) i

To @ZZ whom t may concern: v

Be it known that I, WILLIAM GEBHARDT, a citizen of the United States, residing at San Antonio, in the county of Bexar and State of Texas, have invented a new and useful Machine for Rebending Crown Caps or Seals for Bottles, of which the following is a specification.

The invention relates to improvements in machines for rebending crown caps or sealsl bending or flaring to be quickly effected without bending the center of the cap inward and without loosening the cork.

A further object of the invention is to provide a simple and automatic device for freeing the cap or seal from the female die after lit has been operated on.

The invention consists in the construction and novel combination and arrangement of parts hereinafter vfully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure lis an elevation of a rebending-machine constructed in accordance with this invention. Fig. 2 is a vertical longitudinal sectional view. Fig. 3 is a horizontal sectional view. Fig. 4 is an enlarged detail sectional view showing the dies in engagement with a'seal or cap. Fig. 5 isan elevation of a seal or cap, showing the same after use.

Like numerals of reference designate corresponding'parts in all the iigures'of the drawings.

l designates a frame provided at its lower end with a base 2 and having a tubular portion 3 at its upper'end to form a guide for a vertically-reciprocating plunger 1:,whichcar-v ries an upper male die 5. The base is designed to be mounted upon a suitable bench or support, and it is provided with perforations for the reception of fastening devices Afor securing the frame in position.

vouter end of the gear.

The vertically-reciprocatin g plunger is pro-4 vided at. its inner side with teeth 6, which mesh with a gear 7, j ournaled in suitable bearings of the upper portion of the frame, such bearings S being horizontal and intersecting the tubular portion 3 at a point'between the ends thereof. The gear 7 has one end, 9, ex-

',tended beyond the bearing and perforated Yforrthe recept-ion of Aa handle or lever 10, 4which is secured in place by a set-screw ll,

mounted in ay threaded perforation of the The other end, 12, of the gear is slightly reduced, and the adjacent bearing forms a partial cap for the same.

The frame is provided at the front end of the base with a tubular seat or socket 13, in which is arranged a removable'female die 14, which cooperates with the upper male die 5, and the latter has a threaded stem l5, which fits in a corresponding socket of the plunger. The dies areremovable, in order'that different sizes may be employed. 'The' upper die is provided with a rounded lower end 16, and the central portion thereof is adapted to engage the cork of ,a crown-sealV before the crimped edge thereof is operated on, whereby the central portion of the seal is prevented from being bent inward and loosening the cork. vided with an exterior shoulder 17 to engage a shoulder of the socket or seat 13, and within .the lower or female die is arranged a vertifcally-movable core 18, forming a bottom for the die and normally projecting upward, so as to receive the crown-seal before the same engages the body portion of the lower die,

and this movable inner core, which is yield- .ingly mounted, is 'adapted to compensate for crown-seals of different thicknesses, and its upper end, which forms a bottom for the vfemale die, is slightly concaved or dished to The lower die, which is tubular, is pro- IOO the frame, is provided at its lower end with a return bend.22,its lower terminal being threaded and engaging the socket of the core, and

the nut 23 is disposed on the threaded lower end of the rod to support a disk or washer 24 and to serve as a jam-nutto lock ythe core against rotation. The disk or washer forms a seat for a spiral spring 25, which is coiled around the stem of the core and interposed between the lower disk or washer 24 and an upper ring or washer 26.

y The upper end 27 of ythe rod is vcurved to form a partial hook, which engages a cam 28 of the gear 7. The cam is formed by annularly grooving the gear at a point between the 'ends of the teeth, the groove varying in depth to form an eccentric or cam, as clearly illustrated ,in Fig. 2 of the accompanying drawings. When the plunger moves upward, the cam lifts the rod and the core, and thereby releases the cap or seal and prevents the latter from remaining in the femaledie. As the plunger moves downward the spring causes a positive downward movement of the rod, and the latter has sufficient resiliency at the bend to allow for any variation in the thickness Vof a seal or cap. y

By arranging the upper-curved end of the rod in the groove voi the gear the latter is detachably retained in its bearings, as clearly illustrated in Fig. 3 of the accompanying drawings.A c

By making the Ycentral portion of the male die Yof greater length, the device will be adapted for operating on the crown seals or caps after the cork-disks have been removed, the central portion when extended in this maf-nner being adapted to engage and prevent the latter and prevent it from sticking therethe central portion of 'the 'cap from bending inward.

` y The invention has the followin g advantages:

The machine, which is simple and comparatively inexpensive in construction, is adapted for rebending or flaring crown seals or caps after they have been used and are "of the lshape illustrated in Fig. 5 of the accompanying drawings, and it iscapable of engaging the 4central portion of lthe cap or seal before .operatingy on thecrimpededge, so that there is no liability of bending the said `central portion inward and loosening the cork. The flaring action 'of the lmachine does not injure the crimped edge of a seal'or 'cap,`and it will enable the same to be reused a rconsiderable number of times. The vertically-movable core which forms the bottom of the vfemale die engages `the Ycap or seal before the edges thereof strike the body portion Vof the lower die, and it is also adapted to lift the cap from The dies are removable, so that different sizes may be employed to adapt the machine for operating on caps or seals of various sizes.

Changes in the form, proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of this invention.
