Similar characters of reference refer to similar 45 cam 26, upper plunger 21, label holding means 28, yieldable cover 29, rod 30, lever 3I, shaft 32, connecting means 33, guide 34, lever 35, shaft 36, cam rider 3!, under plunger cam 38, countershaft 39, sprocket and chain means 40, bearings 4|, segmental spur gear 42, pinion gear 43, shaft 44, bearing caps 45, label carriers 46, guide member 41, brackets 48, carrier return members 49, segmental bevel gears 50, springs 5 I adhesive supplying rollers 52, adhesive receptacles 53, label support 54, sleeve 55, guide 56, rod 51, tension spring 58, roller 59, lever 60, cam rider 6|, cam 62, return spring 63, carriage frame 64, can gripping member 65, springs 66, arms 61, wheels 68, track 69, levers III and II, push rod I2, and spring 13, constitute the principal parts and portions of my novel can wrapping and labeling machine.

A framework I is provided which may be common to the feeding mechanism used in conjunction with my can wrapping and labeling machine,

such feeding mechanism being omitted from the drawings. The framework I includes side members Ia which support therebetween a table 2. At one side of the table, midway between the side members Ia, there is provided a can receiving frame 3, which may be formed integral with the table 2. The can receiving frame 3 projects above the normal level of the table 2 and is provided with a centrally disposed oval shaped recess 3a, disposed with its longest axis lengthwise with the machine, that is parallel to the side members Ia. One entire longer side of the recess 3a is cut away so as to form a gateway 3b intersecting a side of the can receiving frame 3. The gateway extends below the normal bottom of the recess 3a and is adapted to receive a gate member 4. The gate member 4 is complementary to the oval recess 3a, that is its inner side is semi-oval and when the gate is in its upper position entirely closes the gateway 3b. The gate member 4 shifts from a position below the normal bottom designated 3c of the can receiving recess to a position in which the upper side of the gate is flush with the top of the can receiving frame as shown in Figs. 3 and 5. A centrally disposed operating rod 5 extends downwardly from the gate 4 through a suitable guide 211. depending from the table 2 and terminates in a bearing which supports a cam follower 6. The cam follower operates in a cam channel formed in a gate operating cam I. The cam I is mounted on a cam shaft 8 which is driven by any suitable means not shown and is disposed transversely with the framework so as to extend underneath the can receiving frame 3.

The oval-shaped bottom portion 30 of the can receiving frame is in turn provided with an ovalshaped recess in which is mounted the flat head of a bottom plunger 9, as shown in Figs. 5, 6 and 9. The can receiving frame or the table supports a guide 21) mounted below and in centered relation to the bottom plunger so as to receive a depending operating rod II], which extends downwardly beyond the guide 22) and is provided with a bearing for supporting a cam rider wheel II, adapted to operate in a groove or channel formed in a bottom plunger operating cam I2 mounted on the cam shaft 8.

A bracket 20 extends laterally from the guide 21) and is adapted to hinge a cam ejector lever I3. The lever i3 comprises an outwardly extending portion I30. terminating in an arcuate arm portion I3b having a curvature concentric with the axis of rotation of the lever. The extremity of the curved arm I3b is provided with a cross member I3e which fits in and conforms with a slot 3d formed in the sidewall of the recess 3a opposite from the gateway 3b as shown best in Fig. 9. The ejector lever normally occupies a position in which the cross portion I30 is substantially flush with the sidewall of the recess 3a as shown in Fig. 5. The ejector lever is provided with an arm I3e which extends outwardly and downwardly from the bracket 2c and is provided with a cam rider I4. The cam rider I4 rides upon an ejector operating cam I5 which may be formed integrally with the bottom plunger cam I 2. The ejector operating cam I5 in such a case is formed onthe opposite side of the cam I2 from its channel as shown best in Fig. 5 and is in the form of annular track the surface of which extends radially with respect to the axis of the ejector lever at the portion engaged by the cam rider I4. A substantially axially extending boss I5a acts to shift the ejector lever to the dotted line position shown in Fig. 5. The ejector lever is held against its cam by means of a coil spring I6, which may be associated with the bracket 20, as shown best in Fig. 7.

The marginal portions of the can receiving frame 3 surrounding the recess 3a, as well as the top of the gate 4, is covered by wrapper margin folding plates I! and I8, and I9. The plates I1 and I8 are positioned adjacent the can receiving frame 3 and are hinged together at their one ends by means of a swivel bracket 2|. These plates are similar in form and are adapted to extend from their connected ends around opposite sides of the recess 3a, their inner edges designated Ma and I8a. being curved to approximate the form of the recess 3a. The extremities of the plates I1 and I8 are provided with angularly disposed slots Nb and I8b, through which extend guide pins 20, fastened into the can receiving frame 3. The slots I11) and l8b are so arranged that when the secured ends of the plates I1 and I8 are shifted toward the recess 30., the extended ends of said plates move toward each other so that the curved inner margins Fla and 18a of the plates overlap the margins of the. recess 3a as shown in Figs.

1, 5 and 6.

The plate I9 fits on top of the plates I1 and I8 and is substantially co-extensive with the top of the can receiving frame 3. The plate I9 is provided with an oval-shaped aperture I9a which is somewhat larger than the recess 3a, so that when the plate I9 is centered with respect to the recess, the margins thereof are exposed as shown in Fig. 2. The plate I9 is provided with slots I9b at one end and a slot I at its opposite end disposed parallel with the longer axis of the recess 3a. The slots I 9b receive the guide pins 20 while the slot I90 receives the shank of the swivel bracket 2|. The latter slot is of sufficient length to permit the relative movements of the several plates. The end of the plate I9 having the pair of slots I9b is provided with a depending bracket 22, corresponding to the swivel bracket 2|. The two brackets are connected to corresponding ends of a pair of levers 23, as shown best in Fig. 6. The levers 23 are L-shaped and are journaled intermediate their ends from lugs 3e, extending outwardly and downwardly from the can receiving frame 3. The remaining legs, designated 23a, of the levers 23 extend toward each other and are joined to a connecting bar. 24a of an operating member 24. The connecting bar 24a passes around the guide 2b and one end thereof is provided with a depending rod 24b, which extends downwardly through a guide 2d supported from the side of the guide 2b.

ward each other by action of the levers 23,.they

together delineate an oval-shaped aperture which is centered with respect to the depression or recess 3a but which is less in diameter.

Mounted above the recess 3a and in centered relation therewith is an upper plunger 2'I, which conforms in shape to but is slightly smaller than said recess. A longitudinal slot 21a is formed in the plunger 21 which receives a bar 28a forming a part of a label retaining means 28. Guide pins 28b extend upwardly from thebar thru the plunger, and are secured to a cross plate 280 which is provided with a centered opening. boss 21b of the plunger extends upwardly through the cross plate 280. A guide rod 30 is secured in the boss and secures a collar 30a to the upper end of the boss, said collar is provided with a pair of diagrammatically disposed journal lugs 30b, one of which isengageable by a catch lug 28d pivotally supported from the plate 280. A spring 28c tends to force the catch into engagement with its pin, such connection being made when the bar is in its retracted position. Another spring 28 extending between the collar 30a and'cross plate 280 tends to force the bar to an extended position. A yieldable cover 29, preferably formed of rubber covers the bottom face of the plunger 21 and bar 28a.

The rod 30 extends upwardly and through a guide Ib which is supported on a cross member to forming a part of the framework I. The guide lb carries a lug Id. The catch 28d has an arm 28g. The lug and arm engage when the plunger reaches its extreme upper portion to release the catch 28d. 7 p

The journal pins 2'Ie fit in slots provided in a yoke 3 Ia mounted at the extremity of a lever 3|. The lever 3| extends upwardly and away from the rod 30 and is journaled on a shaft 32 supported from the framework I. The other or remaining arm 3Ib of the lever 3| continues from the shaft 32 and is connected to the upper end of a connecting means 33.

The connecting means includes a rod 33a which extends downwardly through a' guide 34 supported from the framework I. The rod 33a terminates in a socket 332) into which fits a secnd rod 33c. The rod 330 and socket 331) are limited in their relative axial movement by means of a slot and pin arrangement 33d. Shoulders are provided on the rods 33a and 33e, between which is disposed a stiff spring 33e of greater strength than the spring 28f between the retaining means 28 and the upper plunger 21. The lower end of the rod 330 is connected to one arm of a lever 35 which is journaled intermediate its ends upon a shaft 36 also supported from the framework I in any suitable manner not shown. The remaining arm of the lever 35 is provided at its extremities with a cam rider 31 which is adapted to fit in a'suitably formed channel provided in the side of a cam 38 mounted on the shaft 8. The arm 3Ia of the lever 3| is preferably offset laterally with respect to the other arm of said lever in as much as the cam28 is offset laterally with respect to the axis of the upper plunger.

The main or cam shaft 8 drives a countershaft 39 by means of a chainand sprocket means 40.

The countershaft 39 is hung from the table 2 by means of bracket bearing 4|, and supports a centrally positioned segmental spur gear 42.

Above the segmental spur gear 42, the table 2 is raised forming a platform 2e which is centered with respect to the can receiving frame and extends outwardly'at one end thereof. The

platform 2e is provided with a slot 2f which continues to the can receiving frame 3 so that the bracket 22 and its lever may extend downwardly therethrough as shown in Fig. 6.

The slot 2f is adapted to receive a pinion gear 43 which is adapted to engage the teeth of the segmental spur gear 42. The pinion gear 43 is keyed on a shaft 44 which extends across the platform 26 in bearings 2g formed therein over which are the bearing caps 45. The extremities of the shaft 44 protrude slightly beyond the platform 2e at both ends and are joined at the opposite ends by hinges 460. to arms 46b of label carriers 46 of which there are two oppositely disposed. Each label carrier 46 is provided at the extremity of its arm 46b with a pair of oppositely disposed label carrying plates 466, shown best in Fig. l of the drawings, one extending laterally from the top side of the arm 46b and the other extending laterally from the bottom side of said arm 46b. Therefore, there is provided one label carrying plate 460 on each arm 46b which cooperate for carrying a label, and the other plate 460 cooperates in the opposite direction for carrying a label to the other can. Each label carrying plate is arcuate in form and of such a size as to fit within and adjacent the margins of the wrapper margin folding plates, when said plates are in their contracted or inner positions. The upper plates of the two carriers are complementary and work together to place a label on each side of the can at the left side of Fig. 1, as do also the lower plates place a label on each side of the can at the right side of Fig. 1. During their carrying movement, the arms 46b extend at right angles to the shaft 44 and thereby rotate about a horizontal axis from. a position at the side of the platform 2e, remote from the can receiving frame to a position in which the co-acting pair of plates 46c register with the aperture 3a. On return movement, the carriers rotate about a vertical axis; that is in a horizontal plane. In order to guide the arms 46b in such movement, the bearing caps 45 are provided at their extremities with upwardly extending guide walls 4511, which coact with guide walls 41a of guide members 41. The guide members .4! are supported from the side members Ia and extend inwardly therefrom over the table 2 in spaced relation thereto so that the guide walls 41a form with .the guide walls 450 a pair of slots as shown best in Figs. 1 and 10. These slots designated A guide the arms while they rotate about a horizontal axis. The table 2 at either side of the platform 2c is provided with semi-circular slightly elevated guide portions 2h, which coact with corresponding guide portions 411; provided on the under side and. at the extremities of the guide members 41, thus the guide portions 2k and 41b form horizontal guide slots B.

Secured to the under side of the platform 2e on either side of the pinion gear 43 are a pair of brackets 48 which extend downwardly and outwardly and terminate in upwardly directed spindles 48a, having their axes in approximate alinement with the center of movement of the hinge members 46a. Journaled upon each spindle 48a is a carrier return member 49 which comprises an arm 49a terminating in an upwardly directed pin 4% which projects through an arcuate slot 29' on the raised guide portion 2h and terminates in a roller 490. The rollers 49c are adapted to engage the sides of the arms 46b and shift them laterally away from the can receiving frame in the direction, of the arrows shown in Fig. 1. The carrier return members 49 are provided with segmental gear portions 4911 which are adapted to engage segmental bevel gears 59 mounted on the countershaft 39. Springs 5| are provided which connect with the carrier return members in such a manner as to return said members to their starting position as. soon as the segmental gear portions 49d are disengaged by the segmental bevel gears 50.

The lowermost label carrying plates 460 of the label carriers engage adhesive supplying rollers 52 during their return movement. The rollers 52 are mounted in receptacles 53 which are set into the table 2 shown best in Fig. 5.

Underneath the position occupied by the lower pair of label carrying plates when the label carriers are in their extreme return position, there is mounted a label support 54, which comprises a platform 54a with upwardly directed guide walls 541) suitably spaced so as to retain a stack of labels designated L, as shown in Fig. 3. The support is mounted on a sleeve 55 which extends downwardly through a guide 56 supported from the framework I. A rod 51 extends upwardly into the sleeve 55 and is provided at its lower or protruding end with a roller 59. Between the inner extremity of the rod 51 and the inner end of the sleeve 55, there is mounted a tension spring 58. The roller 59 engages one end of the lever 60 which is fulcrumed intermediate its end upon the shaft 36. The remaining arm of the lever 69 is provided with a cam rider 6| which engages the periphery of a cam 62 mounted on the cam shaft 8, as shown best in Fig. 4. A spring 63 is disposed between the extremity of the rod 51 and the guide 56 and tends to maintain the roller 59 upon the lever 60, and consequently holds the rider 6| against the cam 62.

The can and wrapper is delivered to the wrapping and labeling machine by means of a carriage or the like such as illustrated in Fig. 8. The carriage comprises an oval shaped frame 64, the underside of which is adapted to be coated with an adhesive or to be moistened so as to adhere to adhesive provided around the margins of an oval shaped wrapper W, the adhesive indicated by the character WI. The frame 64 supports a pair of gripping members 65 which are adapted to engage opposite sides of an oval shaped can designated C; such gripping members being held securely against the sides of the can by means of springs 66. These springs surround shafts extending outwardly from the fingers through suitable guides 64a provided in the frame 64. The frame 64 is provided with arms 61 which terminate in wheels 68 or the like adapted to ride upon tracks 69 shown fragmentarily in Fig. 1. This construction may be similar to the feeding arrangement illustrated in my former patent for can wrapping and key placing machine, Patent No. 1,843,458. Of course any other suitable mechanism capable of supplying the can and wrapper in superposed centered relation may be used in conjunction with the present machine.

Operation of my machine is as follows: A suitable carriage member delivers the wrapper with the can thereabove into centered relation with the recess 3a.the lower plunger 9 and upper plunger 21 are then shifted toward the can and wrapper and engage the same. Whereupon the two plungers move downwardly together pulling the adhesive coated marginal portion WI of the wrapper away -from the carriage. Downward movement of the plungers into the recess 3a causes the margins of the wrapper to be folded upwardly as shown in Fig. 12; the upper plunger 21 then moves upwardly until it is clear of the label carriers 46 as shown in Fig. 13. These two members are rotated in a horizontal axis with a pair of the label carrying plates in complementary relation and carrying a label designated L. During this movement, the margin folding plates I], I8 and I9, move toward each other so that their inner curved edges engage the protruding portions of the wrapper and force them inwardly over the top of the can C as shown in Fig. 13, and also indicated in Figs. 5 and 6. The label carriers bring the label into superposed relation with the can, the label being sufiiciently small in area to fit within the aperture delineated by the plates I'I, I8 and I9 when in their inner positions. The upper plunger then returns to its lower position shown by dotted lines in Fig. 3, which is similar to the position shown by solid lines in Fig. 5, whereupon the bar 28a presses the central portion of the label firmly against the can. This movement of the upper plunger is such that its marginal portion 21b does not bear against the label carrying plate. It should be noted here that the movable bar 28a fits within the oval shaped space formed by the complementary pairs of label carrying plates. While the label is held by the tension of the bar 28a against the can, the carriers are started out on their return movement and therefore pull under the label. As soon as this is accomplished, a slight additional movement of the upper plunger causes the marginal portion 2'") thereof to press firmly against the can, and causing the catch to lock the bar with retracted position until the plunger is again raised to its extreme upper position. Thereupon the upper plunger again raises part way, as shown in Fig. 14, and at the same time the gate 4 moves downwardly. The end of the ejector lever I3 moves inwardly, as shown in Fig. 15 so as to push the can out of the gateway 3b and on to a suitable chute 2k supported from the table 2.

As soon as the ejector lever l3 returns to its position, the bottom plunger 9 is on upward movement and another can and its wrapper is delivered between the upper and lower plungers.

During the period following the return movement of the label carrier, and before they again start on their operating movement, the label support 54 is shifted upwardly by action of the lever 60 and can 62 until the uppermost label engages the lower pair of these plates, being the ones in complementary relation. This pair of plates has received adhesive, when said plates passed over the adhesive applying roller 52 during the return movement of the label carriers. The tension spring 58 enables the label support 54 to stop whenever the labels engage the label carrying plates. In order to retain these plates in position against the action of the tension spring pressing upwardly thereon, there is provided a pair of levers l0 and H, suitably supported from the frame I in such a manner as to be engaged zy a push rod 12 supported from the lower end of the rod 51 as shown best in Fig. 3. The lever 10 is normally held out of the road by means of a spring I3.
