' 981,861. Specification of Letters Patent.

Application filed September 23,1908.

To all whom it may concern:

Be it known that I, AXEL JOHNSON, a citizen of the United States, residing at Oak land, in the county of Alameda and State of California, have invented certain new and useful Improvements in Can End Feed Mechanism, of which the following is a specification.

The hereinafter described invention relates to an improved apparatus for feeding and delivering can ends to the mechanism for applying ends to can bodies, preferably to the machinery carrying filled cans to which an end is to be loosely applied prior to such filled cans being conveyed to the crimping mechanism for securing the end to the filled can, the working of the can end feeding apparatus being proportioned to themovement of the carrier mechanism to which radial seats 7 of the carrier disk 6, the end to indicate a suitable supporting structure carrying a spaced bearing thimble 2, through which extends a vertically disposed drive shaft 3. The bearing thimble 2 supports a fixed table or disk 4, from which upwardly springs an inclined curved deflecting wall 5.

To the upper end of the drive shaft 3, extended a slight distance above the table or disk 4, is secured a horizontally disposed I carrier disk 6, which is cut out gt intervals to provide a series of radial can head seats 7, into which the can heads or ends 8 rest as propelled or conveyed toward'the can 9 contained on the carrier mechanism.

The can heads or ends 8 are delivered to the rotatable carrier disk 6 by means of the vertically disposed feed runway or chute 10, the .ends being fed into the runway or chute preferably by hand. The can heads or ends are held positioned within the feed runway or chute 10, by means of the downwardly extended guide plate 11. However, any

suitable form of feed means may be em-' ployed for delivering the can heads or ends 8 within the sphere of thecarrier disk 6, The lowermost or bottom can head or end 8 of the series of heads or ends within the feed runway or chute 10, rests in a vertical position on the upper surface of the fixed table or disk 4, and is engaged by one of the extended portions 12 of the rotatable carrier disk 6 during its rotary movement, which engaging projection as carried past the run way or chute 10 gradually forces the lower can head or end from within the said runway or chute 10 and against the surface of the inclined curved deflecting wall 5. As the can head or end 8 is moved over the surface of the said deflecting wall 5, it is gradually thrown from a vertical position into a horizontal one and within one of the or head. vhen so positioned restingon the surface'of the stationary table or disk 4, which supports the same as gradually conveyed by the movement ofithe carrier disk 6 toward the discharge outlet portion 13 of the table or disk 4,"which, in the present casefis formed by removing a section of the said table 4, Fig. 1 of the,drawings. However, the can head or end 8 is confined within its seat 7 of the carrier ('5, after being conveyed beyond the deflecting wall 5, by means 'of the curved guard plate or flange 14, which upholds or supports the can head or end 8 until properly positioned for discharge.

The drive shaft 3 of the apparatus has secured to itslower end a gear 16, which meshes with a drive gear 17, actuated by.

any suitable form of mechanism, not shown.

In the present case the can head or end feeder is illustrated in connection with a carrier mechanism for conveying filled cans 9 to have an end or head loosely applied to the open end thereof, prior to having the same crimped or permanently secured there-' to. A simple form of such carrier for the filled cans 9, comprises two spaced carrier disks 19-19, separated by a spacing thimble 20, the said carrier disks being secured to a vertically disposed drive shaft 20, which shaft is driven by any' suitable form of drive mechanism connected with the drive means ,for the can head or end feeding apparatus. file drive shaft 20 is extended through a stationary supporting table or platform 21,

onto which the filled cans are placed, the same resting within the alined'can seats 22 of the carrier disks 19-49, beingheld therein as conveyed toward the feeding apparatus for the can heads or ends by means of the curved guard flange or rail 22, secured to and projecting above the surface of the supporting table or platform 21. The can carrier is arranged adjacent to the feeding apparatus for the can heads or ends,

and so disposed that the open end of the filled can 9 passes immediately beneath the dischargeopening or outlet 1350f the supporting table or disk 4, as propelled over the surface of the supporting table or platform the carrier disks 19-l9, the can as thus carried beneath the outlet or discharge opening 13 receiving the can head or end as it falls or drops therethrough in a horizontal position. After the head or end S has been loosely applied to the filled can 9, the said can with its loosely applied head or end is removed from the can carrier and delivered on to a crimping machine, not shown, in order to have the head or end permanently secured thereto.

While the can head or end feeder has been described and illustrated in connection with carrier mechanism for filled cans, it is obvious that its use is not so confined, inas-,

much as the carrier mechanism for the filled cans may be considered as representing any form of rotatable mechanism or device for receiving'the can heads or ends from the feeding apparatus, as for instance rotating means for applying a layer of liquid cement or paste to the flange of the head or end to be applied to cans or can bodies.

Having thus described the invention, what is claimed as new and. desired to be secured by Letters Patent isv 1. In an apparatus for delivering can ends to a rotatable carrier for filled cans, the combination with a stationary table having an outlet or discharge portion for the can ends, of a rotatable carrier for conveying filled cans beneath the discharge portion of 'the stationary table, a carrier disk provided with radial seats rotatably mountedon the stationary table, a vertically disposed runway for delivering can ends onto the said table in vertical position, an inclined deflecting wall secured to the table for gradually throwing the can end into a horizontal position as removed from its runway by the action of the carrier disk, and a curved guard plate secured to the stationary table for confining and guiding the can end'to ward the discharge portion of the table as propelled by the carrier disk..
