MECHANISM FOR FEEDING CAN-BODIES AND CAN ENDS TO A CAN-MAKING- MACHINE.

Application filed February 24, 1911.

To all whom it may concern Be it known that I, LOUIS C. KRUMMEL, a citizen of the United States, residing at Clinton, in the county of Middlesex, State of Connecticut, have invented certain new and useful Improvements in Mechanism for Feeding Can-Bodies and Can Ends toa Canillaking Machine, of which the following is a description, reference being bad to the accompanying drawing and to the letters and figures of reference marked thereon.

The invention relates to new and useful improvements in mechanism for feeding can bodies or for feeding can ends to a can making machine. and more especially to a can making machine wherein the can end is connected to the can body by a rolled scam.

in object of the invention is to provide means independent of a continuously rotating carrier for feeding can bodies to operating members carried by and moving with the carrier, which means sustains the can body until engaged by the operating members.

A further object of the invention is to provide means for feeding in a similar man nor, an ends, together with the can bodies and for sustaining the same until the can end is clamped to the can body.

A further object of the invention is to provide means of the above character with devices whereby the same maybe readily adapted for can bodies of different sizes.

These and other objects will in part be obvious and will in part be hereinafter more fully described.

in the drawings which show by way of illustration, one embodiment of the inventicn: Figure 1 is a vertical sectional view through a rotary double seaming machine, showing my invention applied thereto; Fig. 2 is a longitudinal sectional view of the same: Fig. 3 a detail sectional view on the line 3, 3, of Fig. 1; Fig. 4t is a detail sectional view on the line t, l of Fig. 1; Fig. 5 is a horizontal sectional view through the post for moving the can bodies and ends on the support; Fig. 6 is a sectional view on the line (3. 6. of Fig. 1; Fig. 7 is a plan view of the can body support; Fig. 8 is a vertical section on line 8-8 of Fig. 7.

In carrying out my invention, I have provided a supporting base 1 from which rises standards 2, carrying an axle 3 on which rotates a sleeve 1. The sleeve is rotated by means of a gear which is connected with Specification of Letters Patent.

Patented Mar. 24, 1914.

Serial No. 610,464.

a gear 6 on the main shaft. Mounted on the sleeve at is a bracket 7, which carries a plurality of bearings 8 in each of which is mounted a rotating chuck 9 carried by a spindle 10 operated by a gear 11, which is connected to a gear 12 carried by a sleeve 13, which is operated by a gear lat meshing with a gear 15 on the main shaft. As all the operating stations are identical, I shall only describe one of them.

Cooperating with each rotating chuck, is a second rotatable member 16. Said rotatable member is formed with a head 17 adapted to fit the open end of the can body, and a collar 18 is normally spring-pressed outwardly against said head by the springs 19. The, rotatable member 16 is carried by a sliding member 20 which is moved in and out of the supporting bracket 21 carried by the sleeve 1, by a cam 22 which is freely mounted on the bracket 21 and held from movement by a pin 23, which extends through one of the standards 2.

Extending through the spindle for the chuck. is a rod 24. which carries a. seating pad The rod 24 is normally held seated within the chuck by a spring 26 (see Fig. 2.) The outer end of the rod 2st is formed with a hardened projection 27 which at times ongages the cam 28, which is carried by the supporting frame of the machine, and this cam causes the seating pad to be moved from the chuck into engagement with the can end. hfounted also on the carrier and r0- tating therewith, are a plurality of seaming toolsor rollers 29. These rollers are mounted on carriages 30 which are swung about their pivots by stationary cams 31 mounted on the rotating sleeve.

The cams 31 may be held from rotating by any suitable means such as an arm which extends outwardly and engages some fixed part of the machine. These cams as clearly shown in dotted lines, in Fig.1, extend only part way throughout the circumference of the supporting sleeve, and will operate therefore, to move the seaming rolls into and out of operative engagement with the can ends during each rotation of the carrier. Two cams are provided, one operating the first curling roll, and the other the flattening roll.

The above described parts form no part of the present invention per se, but have been described as a preferred mechanism for operating upon the can bodies and can ends which are fed thereto by my improved feeding mechanism. The parts herein described are more fully shown, described and claimed in my copending application #535,680, filed December 30th, 1909.

As a means for feeding can bodies to the operating members on the rotating carrier, I have provided a can body support which is stationary relative to the carrier. Said can body support is mounted on suitable brackets 32, which are adjustably supported by rods 32 The upper rod 32 is carried by vertical arms 32, which are secured to the end standards of the machine. The lower rod 32 is secured to laterally projecting arms 32 which are also attached to the end standards. The ends of the brackets 32 are split and are clamped by suitable nuts to the rods 32 Attached to the brackets by suitable screws, are supporting plates 34. The can body chute, is formed by spaced side rails 33, which are riveted to the supporting plates 34. As herein shown, the spaced guide rails 33 are deflected laterally at their lower ends so that the can bodies as they are leaving the guide rails, will move substantially in a radial direction relative to the carrier. It is obvious however, that the guide rails of the chute may be straight throughout their entire length, or located in other positions, if desired. A plate 34 is attached to the lower end of each set of the guide rails 33 and projects laterally relative to the plate 34, and serves as a means for supporting the guiding rails 35 and 36 for the can bodies. The guide rail 35 is riveted to the plate, while the guide rail 36 is preferably pivoted to the supporting plate 34, as will be hereinafter more fully described.

The guiding rails 33 which form one side of the hute, are also grooved as at 33 (see Fig. 7 to form a guiding channel for the can end, so that the can ends may be fed to he carrier in substantially the same way as the can body is. The guiding rails 35 (as shown in Fig. 3) are curved concentrically tothe axis of the rotating carrier. It will be obvious however, that from certain aspects of the invention, these supporting rails may not necessarily be curved concentrically to this axis, but may be otherwise shaped, or straight, the essential feature being a supporting means on which the can bodies may be given a movement in the general direction of the movement of the carrier, before they are clamped by the chuck of the seaming mechanism. The can bodies and can ends will drop from the vertical chute on to the guiding rails 35 along which they may be moved in a forward direction. The guiding rail 35 at the left hand end of the can body, (as shown in Fig. 3) is provided with an upwardly projecting supportingrib 37 on which the can body rests, and

a flange 38 which projects above the lower portion of the end of the can body to pre vent the same from endwise movement on the rails. The rib 37 is so placed however, as to allow at a proper time, a movement of the can body on the rib without the flange on the can body striking said rib. The upper rail 36 at the left hand endof the can 7 flange 42 which )ro'ects u )WELICll above the lower portion of the end of the can body and also with a second flange 43, similar to the flange 42 but spaced therefrom, to form a channel 44 for the can ends. The upper rail 36 at the right hand end of the can body as viewed in Fig. 3, is formed with spaced flanges 45 and 46, which are similar in construction and operation, to the flanges 42 and 43. These flanges 45 and 46 form a channel for the can ends. At the left'side of the upper right hand rail 36. is a plate 47, which is formed with a retaining rib 47*, similar to the rib 39 on the other rail 36. Each of the rails 36 is pivoted at 48 to its supporting plate 34 Also the plate 47 is pivoted in a similar manner. The guiding rails 36, and the plate 47 are normally spring-pressed downward, by springs 49. A pin 50 carried by the supporting plate 34 and extending through an enlarged opening in the plate 47 and the rail 46, limits the movements of both, under the influence of the springs 49 which bear thereon.

l/Vhen the can body is passing between the rails 35 and 36, the left hand rail 36 and the plate 47 will be pressed against the can body. This forms a slight drag on the can body and holds it properly against the member moving the same against the support which will be hereinafter more fully described. The rail 36 at the right hand end will be spring-pressed against the can end, and serve in a similar manner to retard its movement on the rail 35. WVhile I have shown these upper rails as spring-pressed, it is obvious that from certain aspects of the invention, it may be made stationary and I may depend solely upon the inclined position of the rails and the action of gravity to properly hold the can body and can end against the member moving the same.

The can bodies passing down through the chute by gravity will drop on to the ribs 37 and 41 of the supporting rails 35. The can ends will also pass down through their guiding channels in the chute into the channel in the supporting rail 35 at the right of the can body as viewed in Fig. 3. Inthis position, the can body and can end will rest by gravity against the lower end of the left hand guiding rails 33 as viewed in Fig. 8. As a means for moving the can body and can end along the stationary support, I have provided the rotating carrier with a supporting ring 51 which is mounted on projecting studs 52, carried by the bracket 7. Said ring 51 is formed with a flange 53 and at each seaming station I have formed a post 5% (see Fig. 1) which is clamped to a face on the flange 53, by a bolt 55, as herein shown.

The post 5-1 projects laterally and upwardly, and is formed with an enlarged head 55, at its upper end, which carries spaced ribs 56 (see Fig. 5). This post as the carrier rotates will engage the can bodies and can ends resting on the supporting rails 35, and will move the same along the rails at the same speed of travel as the carrier. The spaced ribs 56 will hold the can body concentric with the can end as shown in Fig. 5, so that the can end is in proper position to be seated in the can body.

The flanges 38 and 40 on the guide rails 35 and 36, are cut away near the delivery ends of the rails. so as to allow the head 17 and the collar 18 to be moved inward between the rails 35 and 3(3 and the head 17 to be seated in the open end of the can body. The flanges 42 and 15 are also cut away as shown in Fig. 1, so as to allow the can body to be moved against the can end and the can end seated in the can body (see Fig. 1). The flanges 43 and 16 are also cut away so as to allow the seating pad 25 to be moved against the can end and to seat the can end in the can body, as the can body is moved on to the can end by the movement of the head 17 through the action of the stationary cam 22.

In the operation of my device the can body and can end resting on the supporting rails 35, are picked up by the enlarged head on the post 51 and are rolled or slid along the supporting rails in unison with the travel of the carrier. The (rain 22 moves the head 17 and collar 18 against the open end of the an body, and a continued movement through the action of the cam 22 will move the can body longitudinally on the supporting rails, and carry the same into position to engage the can end. The seating pad 25 is moved up against the can end. A continued movement of the head 17 will cause the end to enter the open end of the can body, and the collar 18 will compress the springs 15) and move back against the member 16. The cooperation of the seating pad 25 and the head 17, together with the collar 18, will cause the can end to be seated in the can body and the can body and can end to be clamped between these parts and moved along with the carrier.

As the carrier continues its movement, the

can body and can end clamped between the seating pad and the head 17, will be carried from between the rails 35 and 36. The head 17 and the seating pad 25 will now be moved longitudinally of the can body, carrying the can body and can end clamped between the same on to the rotating chuck 9, and after the can body is clamped between the head 1'7 and rotating chuck, the seating pad 25 will be released from pressing the can end through the action of the spring 26, and the can body and can end may be rotated together. The seaming rolls are moved into engagement with the rotating can-end first one roll and then the other contacting with the can end to form the usual double seam.

Vhen it is desired to operate upon can bodies of difi'erent sizes, the supporting bracket 21 for the rotating head 17, is moved longitudinally of the sleeve 4. so as to prop erly space the rotating head from the rotating chuck. The seaming rollers are also properly positioned for operating upon the proper size cans. I prefer to form the guiding rails and supporting plates in units wherein the rails are fixed on the plates for the different size cans, and the plate together with the rails are removed and another plate having the rails differently spaced is substituted therefor. It is obvious however, that the rails may be adjusted on the supporting plate if desired. The post 54 will also be properly adjusted relative to the center of rotation of the seaming station for the dif ferent size cans. Mounted on the head 55 of the post 54, is an arm 37 which is pivoted at 58 in a recess in the head 55. This arm projects laterally and is formed with a shoulder 59. A spring 60 holds the arm 57 in position so that the shoulder 59 is in line with the rib 56, and will engage the outer end of the can body as shown in Fig. 5. The arm 57 is yielding so as not to interfere with the proper clamping of the can body and the seaming of the same. For smaller size cans, the arm 57 is removed.

\Vhile I have shown my device as applied to a double seaming machine, it will be apparent from certain aspects of the invention, the means for feeding the can bodies may be used independently of the means for feeding the can ends, as for example in feeding can bodies to a Hanging machine, in which case the can bodies would be held on the stationary support until engaged by the flanging tool.

It will also be obvious that a can end may be fed by my improved means at each end of the can body, as for example, in heading cans.

Various other uses and adaptations of my device will be apparent to those skilled in the art to which my invention relates, and it will be understood that I do not wish to limit myself either to the details of constationary support for the can bodies ex-.

tending from said feeding chute in a direction concentric to the axis of the carrier on which the can bodies may rest and move, and means for moving the can bodies on the support in unison with the movement of the carrier.
