CAN -HA1\TDLING MECHANISM.

Specification of Letters Patent.

Application filed October 21, 1919. Serial No. 332,269.

T 0 all cc ham 2t may concern Be it knownthat I, SYLvns'rnR EBERLY, a citizen of the United States of America, residing at- Toledo,'Lucascounty, Ohio, have invented new and useful Can-Handling Mechanisms,- of which the following is a specification.

This inventionrelates to mechanism for arranging similar or identical articles.

This invention has utility when incorporated in mechanism for grouping cans havingone filling end in a common classification as to such filling end, as for condensed milk plants.

Referring to the drawings:

Figure 1 is a fragmentary plan view of an embodiment of the invention in a machine for handling the talls or long cylindrical cans or containers such as are used for 1 lb. cans of condensed milk and approximating 3 inches in diameter and 1% inches high, with a inch hexagonal hole in one end only thereof as a filling openingcentral of such end;

1F ig. 2 is a detail View of some of the driving'connections for the machine of Fig. 1;

Fig. 3 is a partial view ofthe supply conveyer and up-ending' device for the machine; 1 I

Fig. 4c is a view of the conducting means effecting spaced seating of the cans of the Lip-ended supply;

Fig.- 5 is a view of the sorter as coacting with the seated cans; I

Fig. '6 is a section on the line VI-VI,

Fi J 5" Fig is a view of the take-offcoacting means for the cans left in the seats by the.

sortergand Fig. 8 is a view of the take-off chute and Lip-ending way for sorter-selected cans.

Cylindrical cansl having imperforate bottoms 2, tops3 with central hexagonal filling openings 4 may be in storage bin or box car 5, in ricks ortumbled about. rapid removal of such from such bulk groupings, a workman may have a fork to insert between or under the cans as resting together, andby lifting such fork, a conslderable number of the light empty cans 1 may be removed at a time for deposit inhopper 6 above b'eltconveyer'? to be moved by the conveyerj '7 to slide down supply chute 8 into receiver 9. About a bushel or say fifty.

ofthese cans may be forked at one time.

For the on connected by belt 23 to pulley 24:011 shaft 25 operating the conveyer belt Eccentric 26 on the slow speed motor shaft 12 may, through link 27, rock or shake the receiver 9 on its bearing 28, for continually shifting the cans 1 sliding bv chute 8 into the receiver 9. These cans l as thus rolled and tumbled about into the receiver 9 are readily L p-ended by sliding downward into throats 29 in the bottom of the recelver 9. Such outlet means or throats 29 are concentrically above guides having upper portions 30 tapered outside the taper of the throats 29 to receive cans 1 therefrom. A rigid frame 31 carries the group of guides 30, which have lower semi-cylindrical portions 32 for steadying the cans 1 as sliding downward thereinto to be sustained on the table 10. The direction of rotation of the table 10 is such as to withdraw from the guides 32 through the open sides 33 thereof, the cans 1 as lip-ended therein. The. arrangement of the throats 29 is such that in the table rotation, theup-ended cans as drawn from the guides 32 may clear each other. Theex'tent ofthe'guides 32, 30, is such that as long as a can on the table 10 holds a can thereover invthe tapered portion 30, shaking of the receiver not jam or wedge other cans in the throat 29:

As the tableblO moves continuously in carrying up-ended' cans away from the up endin'gshaker device, such cansare directed to a single file traveling series. Central shaft 34 carries a stationary directing frame 35 for urging the cans in a single row adjacent outer stationary frame 36," as the table 10 rotates.

After the directing frame 35 with its yieldable section 37 has effected the single row grouping of the cans 1, Lip-ended but unclassified as to the filling openings l, conducting means comprising chute 38 with Patented Apr. 5, 1921.1

bearings 13, 14:."

. tion of the frame 35, has outer side 40 as a continuation of the frame 36. This side 40 has yieldable section 41, fordirecting the up ended cans as actuated down the chute, 38 by the cans on the table 10, into spaced seats embodying partitions 42' above an annular ledge 43 concentric with the table 10 and as a drop rim thereof. 1 V

The cans 1 are thus arranged in definitely spaced relation in the annular series of seats about the table 10 as a way surrounding andsomewhat below the table top. A stationary holding frame 44 as a continuation of the .-side guideframe 40, retains the cans 1 in the seats, which are soshallow that side portions of the cans project radially out of these seats. r

Concentric with the can when in full seated position, each seat has therebelow a plunger or pin 45 (Figs. 5, 6,), normally held down by a helical spring 46. As the table 10 rotates, the lower ends of these p1ns 45 ride upward on a stationary cam 47.i

This cam 47 is located beyond the end of the frame 44. If the can 1 over the pin45 hasits end 3 down, the pin 45 merely moves upwardinto the hole 4 and does not disturb such can. However, if the can 1 has its bottom end 2 down, there being no opening therein,the pin 45, in rising, lifts such can 1. Asthe can is lifted, inclined headless pin 48, just below the top of the table 10, directs the upper end of the lifted can 1 outward, so that such can is thrown out of the seat onto its side. 'Withthe upward movement of the pin 45, spacing arm 49 rises through opening 50 in ledge 51 as the third or outermost of the annular series of ways carried by the table 10. All of these cans 1 ejected from the seats 42, 48, had their bottom'or imperforate ends 2 down. Thus the configuration of the cans 1 as contacted by the pin 45 of the throw-out device has brought about a selection and classification of certain of. the cans 1. V

There is likewise, left in the seats 42, 43, definitely classified cans 1 all of. those which have the filling opening 4, down. As the table 10 continues its rotation, stationary controlling means embodying a finger 52 below the partitions 42, slides in back of eachof the cans 1 left in the seats on the ledge 43, to urge such cans 1, off upon chute ward, may now pass through cage 55 for bringing the filling openlngs 4 up, and be thence conducted on conveyer cable 56 between stationary guide frames 57, 58,.to a

can filling machine. In practice this conveyer would receive approximately 50% of the cans thrown upon the conveyer belt 7 Thus this machine or can handling mechanlsni may be an automatic adaptation for supplying a plurality of can filling ma chines.

The cans which have been rolled or rocked upon the ledge 51, may have their closed or inner ends engaged by a stationary finger 59, to move these cans 1 radially outward, as the table 10 rotates, for urging along chute 60 as outwardly limited by a guide frame member 61. The cam 4? extends to just short of the linger 59 so that the spacing arms 49 are effective. This means that there .is a positive crowding of these laid-sidewise cans from the ledge 51 into the chute 60. To bring these cans 1 into position to have their fill--' ing openings 4 up, a cage 62 of 90 throw, instead of 180 as is cage 55, swirls these cans for delivery to conveyer cable 63 between stationary guide members 64, 65,:in travel to; a can filling machine. i

i There is accordingly accomplished by the device of this disclosure, an arranged delivery of cans. ,With a six foot diameter table 10 rotating six times per minute, four 1111111 dred one-pound cans per minute are automatically supplied and classified directly to a filling machine by asingle man in the car being unloaded, or in the storage room. The cans are gently handled speedily 'No' harrnis thus done to the containers. The device does not occupy as much space as" would be required by manual sorting, saves such labor, and requires but little power to nlsm for mov ng cans of one end identification structure away. from cans having a different identification structure as to such end.
