- The present invention relates to can feeding devices for accelerating the travel of cans and the like, such as are filled with or have a liquid content so that a greater speed of travel or a greaterflspacing is obtained between cans with out spilling their contents, and the invention has as the principal object the simplification and the more accurate manipulation of such feeding devices.

The invention. contemplates the use 01' three movements or controls for can propelling levers .by means of which the levers are bodily carried in a general circular path of travel, are moved in and out and are also rocked back and forth to effect an accurate control of the travel of the cans being propelled by the levers. v

The inventionhas for a further object the provision of simplified can propelling members which engage a can, filled with a liquid or content like-- ly to be spilled, without sudden jar or shaking of the can and which then gently sweep the can over a path of travel while gradually accelerating its movement or increasing the intervals between adjacent cans engaged byadja'cent lever devices to the end that the transposition from a relatively slow rate of travel into the higher speed will take place in a smooth, uninterrupted and accurately controlled manner.

Numerous other objects and advantages of the invention will be apparent as it is better understood from the following description, which, taken in connection with the accompanying drawings,-discloses a preferred embodiment thereof.

Referring to the drawings:

Figure 1 is a plan view, partially broken away. of a' can feeding device embodying the present invention, this .view illustrating the transfer of cans from a turret member having closely spaced pockets into one having pockets spaced consid-' erably further apart, which requires a greater can travel a Fig. 2 is a transverse sectional viewv taken substantially along the'broken line in Fig. 1;

Fig. 3-is a perspective view of one of the can I propelling levers with its associated mounting;

Fig. 4 is a sectional detail taken substantially along the line M in Fig. l and v I Fig-5 is a plan sectional view taken substantial-'- ly along the broken line 5--5 in Fig. 2.

Movable andstationary parts of the apparatus are carried in a housing 2!! (Figs. 2 and 5) which is mounted upon or formed with a base 22. The housing M is closed at its upper end by a table section 23.

This table may be a part of other machines which deliver cans into and receive cans from the feeding devices and is here shown as supporting a turretmember 25 (Fig. 1) having can receivlngpockets 25 which are relatively close together, this turret member being mounted 5 upon and turned by a vertical shaft ii in any suitable manner. Such turret member illustrates by way oi example the delivering of cans 23 to the feeding devices.

c The cans 28 coming from the member 25 are closely spaced and the feeding devices herein considered advance these cans 28 while separating them and at the Same time accelerate their travel without interrupting or in any way shaking or jolting the cans, such non-spilling i'eal5 ture being particularly desirable where they are substantially filled with liquid or other spillabie material.

In Fig. i there is also disclosed by way of example a can receiving turret member 3: which is here shown as being supported upon the table 23 at its other end, this turret being formed with can pockets 32 which are spaced a considerable distance between adjacent pockets. This turret member 3i may be, mounted upon and rotated 35 by a vertical shaft 33 in any suitable manner.

A track or runway between the members 25,

ll is'provided as a path for the cans being conveyed by the feeding devices and in the embodiment disclosed in the drawings this pathway is w Q 'formed by a horizontal plate (Figs. 1 and 2) which rests upon a raised extension of the table 28. This plate has generally the form oi a widely spread letter v and extends from a position beneaththe turret pockets 26 of the 35 member 25 to aposition beneath the turret pocket 32 of the member it A guide rail 36 is-preferably mounted upon the plate 3t adjacent the turret member It and its inner edge cooperates with the turret pockets 28 to hold the cans within the turret as t latter rotates with its shaft 2?, as illustrated on the right hand side of Fig. l.

A curved guide rail 31! is also carried by the plate 35 and its inner edge cooperates with the peripheral edge of a $5 stationary member 39 which is a part of the can feeding device proper.

As best illustrated in Fig. 2 this plate 39 is mounted upon the upper end of a central post ill which is formed with a base it mounted upon the frame base zt'and secured in fixed position by bolts 63. The periphery one side and the spaced inner edge of the guide rail 37 is of such shape as to direct the cans fill from the turret'member 25 in a path of travel M of the plate 89 along have delivered these cans at the greater rate of travel and at the greater spacing.

The feeding devices proper are carried in a spider 5| (Figs. 1 and 2) which surrounds the post 8| and revolves about it. This spiderlis bolted to the circular head 52 of sleeve 53 which is rotatably mounted on the stationary post. The spider 5| and parts carried thereby are supported upon the table 23 and upon the stationary post, the head .52 bearing upon a circular boss 55 formed in and projecting upwardly from the table and the lower end of the sleeve 53 resting upon a shoulder 56 formed in the base 42 of the post.

,The spider 5| is continually rotated during the operation of the apparatus and for this purpose the lower end of the sleeve 53 is provided with a ring worm gear 51 which is keyed to the sleeve and which meshes with and receives rotation from a worm 58 secured to a drive shaft 59. The drive shaft 59 is journaled in any suitable manner as in a bearing 6| formed in a bracket 62 projecting upwardly and formed as an integral part of the base 82 of the stationary post. and may also be journaled in otherbearings not shown. This drive shaft 59 may be rotated in any suitable manner toreffect rotation of the sleeve58 and the spider 5|.

The spider 5|,is formed with a plurality of radial slots '65 (Figs. 1, 2 and -.4) and slide blocks 88 are carried in these slots. Top. protecting plates 61 are mounted upon the upper surface of the spider 5| and are secured in fixed position by screws 68 so that their side edges extend over the edges of the slots in the spider. This prevents vertical displacement of the slide blocks 86 within the spider and allows for unrestricted radial movement.

Each slide block 66 (Figs. 2, 3 and 4) is formed with an upper boss 1| and a lower boss 2 which are in direct alignment with one anothe and a vertical bore "passes entirely through the upper and lower bosses of the slide block. A can propelling lever'll, illustrated as an angle lever, is carried in each block 66, being formed with a 1 depending stem 15 which is loosely positioned in the bore 18. The weight ofthe lever is supported on the top of the upper boss-1|. Each lever 14 .isformed with two arms,- one having an upwardly extending can engaging finger 16, the

other being a cam roller arm 11. The arm 11 carries a pin 18 on which cam roller 13 is rotatably mounted. A cam grove 8| 2 (Figs. 1 and 2) is formed in a depending cam ridge 82 projecting downwardly from the under surface of the plate 88 and the roller 19 of each lever 18 operates'wlthin the cam groove asthe spider 5| carries'it and its slide block 86 around with it. The stem 15 of the lever 14 projects below the lower end of the boss .12 where it carries a cam As the slide blocks 88 arecarried around by the spiderj'l, as previously described, each cam roller 85 itraverses a cam groove 86 formed ina cam ring 81. This cam ring is formed with a circular flange 88 that rests upon and is bolted to the table 23.

By means of the spider and cam controls of the levers 14 their can engaging fingers 16 are .mountings, as the case may be, to cooperate with brought into engagement with and behind the cans 28 while they are still within the turret pockets 26 of the member 25 and as the spider 5| continues its rotation the cam 81 working through the rollers 85 on the pivotal centers of the levers, slide the blocks 66 of the levers within their radial slots 65. At thesame time the cam" groove 8| operating upon the cam rollers 19 of the levers 14 holds or oscillates them on their pivotal the slide block position so that the fingers 16 re: main against the walls of the cans until the'latter are delivered with the resulting accelerated speed of travel into the pockets 82 of the turret member 3|.

This combination of controls of the pivotal part of the lever and the rocking of the lever effects the desired movement of the engaging fingers 16 of the levers sothat as soon as a turret pocket 26 releases a can 28 the engaged lever finger 16 picks up and gradually accelerates it as it moves between the guide rail 81 and the peripheral edge of the movement is of. such a nature as to uniformly increase the speed of travel of the can without permitting any spilling of the liquid contents and this increasing acceleration also spaces adiacent cans further apa "t so that they are brought into proper spaced position and properly delivered within the pockets 32 of the turret member 8| without any spill of the can contents.

It is thought that the invention and many of its attendant advantages will be understood from the foregoing description, and it will be apparent that various changes may be made in the form, construction and arrangement of the parts without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.
