CAN UP-END ING MECHANISM.

Specification of Letters latent.

Patented Feb; 1, 1921.

Application filed June 11, 1919. Serial No. 303,411.

To all whom it may concern:

Be it known that I, FRANK PILLEY, a citizen of the United States, residing at Kansas City, in the county of 'Jackson and State of Missouri, have invented certain new and useful Improvements in Can Up-Ending Mechanism; and I do 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, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to up-endingmechanism for containers andit is particularly applicable for use in connection with milk can cleaning apparatus.

Milk cans are generally cleaned by being passed in inverted position along a way so that the interior may be sub ected to' the action of'hot water, steam or some suitable sterilizing means. They are then discharged to be deposited upon a runway down which they may gravitate to a collecting platform or base.

I have provided means whereby the inverted cans maybe up-ended between .the point of discharge from the can cleaning apparatus or machine and the runway and I have arranged the up-ending mechanism so that it may be actuated in synchronism with certain elements of the can cleaning mechanism so that the movement of the up-end ing element will be timed with the discharge of the can from the can washing machine.

The invention contemplates the provision of means for receiving an inverted can and for positively up-endin'g it sothat its bottom will rest upon an inclined way or receiving platform and it is the purpose of the invention to accomplish this without dentingthe can.

Other objects and advantages of the invention will be apparent hereinafter by reference to the description in connection with the accompanying drawings, in which-- Figure I is a perspective view of an upending device constructed in' accordance with m invention.

Fig. I is a side' elevational view of the same showing the basket in can-receiving position.

Fig. III is a side elevational view of my invention showing the basket in can-dischargm position.

F 1g. V is a fragmentary view of a rest bar, and

Fig. V is a cross sectional view through the basket showing a buffer roller in elevation.

Referring now to the drawings by numerals of reference:

1 designates a can cleaning machine of approved construction, here shown as being provided with a can guideway 2 and a can top guldeway 3, the tops 4; being shown as secured to the cans 5 by coupling wires 6. In the side of the can cleaning machine is a slot 7 in which is mounted an oscillatory bar 8 pivoted atone end and engaged at the other end'9 by a reciprocatory pitman 10,

' which may be driven by any suitable power.

. way 11 provided with the rollers 12 down which the cans may gravitate.

By reference to ig. I it will be observed that interposed between the runway 11 and the can washing machine is a can up-ending mechanism including a supporting frame 13 at the rear of which is journaled a rock shaft 14 carrying a swinging cradle or basket 15. The basket is shown as consisting of

side bars

16 and 17 "in the form of cranks rigidly secured upon the shaft 14. and the side bars are connectedby a web 18 of metal having a concave portion 19 and a flat portion 20. Extending forwardly of 'the basket and integral with the

side bars

16 and 17 is a substantially V-shaped can tilting member 21, the forward part of which, when the basket is in receiving position, is inclined downwardly, there being a transverse can lip engaging bar or rib 22 at the intersection of the .angles so that when the can is discharged from the can washing machine, the lip of the can will strike against the bar 21 and throw it over into the concave ortion 19, as best seen in Figs. I and II, xtending across the basket is a rod Q3 which carries a relatively soft rubber bufl'er roller 2-1 positioned at the forward end of the corn cave portion 19 so that when the cans are thrown from a vertical to a horizontal osition, they will strike against the r01 er 24 which will receive the impact of the blow and thereby prevent denting of the cans. The. rod 23 is vertically adjustable with

end slots

25 and 26 carried by the forward portions ofthe arms 16' and 17, and said rod may be held in its adjusted position through the medium of the

nuts

27 and 28 on the.

rod 23. The forward end of the swingin member, which includes the basket and the can-receiving portion, is adapted to rest upon a bar or yoke 29 adjustably secured to the top bars of the frame 13 by the fastening devices 30 and 31. The bar 29 is adjustable to provide for different size cans, as is also the rod 23.

have provided mechanism for swinging the cradle 15 in synchronism with the discharging mechanism of the can washing mac ine and this operating mechanism is shown in Figs. I, II and III as including a crank 32, normally depending from the shaft 14 and connected to a sectionally adjustable operating link 33, one end of which is pivoted to the crank 32 intermediate its ends and the other end of which is provided with a latch head 34 extending ad acent to the can advancing or discharging lever 8. The lever 8 is provided with an upstanding lug or projection 35 adapted to engage a notch or projection 36 on the head 34 supported upon the rail 37 by the roller 38 but the head is adapted to be thrown out of engagement with .the lug 35 when the camface 39 of the head contacts with the inclined face 40 of the release cam 41, as will be presently explained.

The end 42 of the crank 32 is connected to a piston rod 43 on one end of which is a piston 44 in a-pivoted dash pot cylinder 45, the piston being free to move from left to right on account of the orts 46rbut the movement in an opposite irection being resisted by the pressure between the piston and the head 47, which can only be relieved through the pet cock 48,the resistance to the piston 44 being controllable through said pet cock.

When the parts are assembled as illustrated in the drawings and the bar 8 moves from right to left to advance or eject a can, the can will be thrown upon the V-shaped can-receiving portion of the cradle so that the lip will contact with the rib 22 whereby the inertia of the can will cause it to tilt over into the concave portion 19 of the basket. By this timethe lug 35 will have ridden over the cam face 39 to engage the notch 36 and as the pitman 1Q moves from left to right under the action of a crank or other appropriate device, the link 33 will move wit it, swingin the arm 32 on shaft 14 so that an upwar rearward swinging movement will be imparted to the cradle, as

.shaft,

indicated in Figs. II and III, so that the can will be carried to a verticaliposition and deposited upon the gravity runway ll top side up. This movement will cause the end 39 of the link 33 to contact with the inclined face 40 of the release cam 41 so as to raise the head 34 out of engagement with the projection 35 and thereby permit the cradle to swing forward to the position shown in Fig. I. The forward swinging movement of the cradle will be resisted, however, by the piston 44 in the cylinder 45 so that the cradle will come to rest upon the bar 29 gradually Without liability of jarring the mechanism.

The cycle of operation just described will be repeated as often as the cans are ejected from the can recleaning machine the can up-ending movement of the cradle being relatively rapid and positively actuated through the bar 8 but the recovery being relatively slow near the final position of rest on account of the dash pot consisting of the piston 44 and the cylinder 45.

From the foregoing description it will be apparent that the mechanism may be readily operated from the power of a washing machine so as to operate in unison therewith and so that the cradle will be in position to receive the cans at each ejecting operation.
