PACKING- DEVICE FOR FILLED-CAN-CLOSING MACHINES.

Application filed July at, 1925. Serial No. 45,886.

The in vontion relates to new and useful improvementsin packing devices for filled can closing machines and more particularly to a packing device which is positively operated and which cooperates with the filled can while the filled can is moving into the closing machine.

An object of the invention is to provide a packing device wherein the overflowing pad is positively moved into cooperative relation with the moving can and is positively maintained in horizontal position throughout the entire movement thereof.

A further object of the invention is to provide a packing device of the above type wherein the overflowing pad is mounted on a positively rotated support and is maintained in horizontal position by a similar positively rotated support set eccentrically to the firstnamed support and carrying a pin cooperating with a crank arm mounted on the shaft carrying the pad so that as the two supports are rotated one support positively rotates the pad into cooperative relation with the can while the other support maintains the pad in horizontal position. 1

These and other objects will in part be obvious, and will in part be hereinafter more fully disclosed. v

In the drawings which show by way of illustration one embodiment of the invention Figure 1 is a view partly in front elevation and partly in section, showing a portion of a filled can closing machine having my improvement applied thereto, I r

Fig. 2 is a sectional view on the line 22 of Fig. 1.

Fig. 3 is a sectional view through the casing for the rotating members and showing the manner of positively rotating one member from the other.

Fig. 4 is a sectional view on the line -ld of Fig. 2.

The invention is directed broadly to a packing device for a filled can closing machine, that is, a machine wherein open ended cans after they are filled are closed by the seaming of the top end to the body portion of the can.

Prior to my invention it has been common to provide a closing machine with a rotating drum having a thread wound thereon, which drum becomes a feeding mechanism for feeding the filled cans to the machine where they are closed. The thread on this drum slides the cans one after another along a horizontal stationary support. Located above this sup? port for the Cans is a packing device which includes a pad adapted to move down onto the filled can for the purpose of depressing any floating fruit or vegetables down into the can, and thus properly overflowing the can so that it is in condition to be closed with a minimum amount of spill. y

The present invention is directed particularly to the means of supporting and operating this overflowing pad.

This means includes a rotating disk or traveling member in'which the supporting shaft for the pad is mounted and on .the rear end of said shaft is a depending arm. Located in the rear of the supporting disk is another traveling disk having a stud adapted to engage the free end of the crank arm. This last-named disk is positively rotated and becomes the driving disk for actuating the pad. There is a counter-shaft which connects the two disks together so that one rotates the other.

Referring more in detail to the drawings, the machine includes a main frame 1 on which is adjustably mounted a table or bracket 2. Carried by this table 2 is a shaft 3, which is mounted in suitable bearings supported on the table. Mounted on this shaft 3 is a drum 4, having a spirally wound thread 5. Associated with the drum 4 is horizontal support 6, and the can which is indicated at C in the drawings rests in part upon this horizontal support 6 and in part on the drum 4: and is moved along continuously by the thread on the drum. Thus it is the cans are delivered one after the other onto a support 7 which cooperates with the closing mechanism, wherein the end is seamed onto the can body. As the cans are moved along the sup port therefor, an overflowing pad 8 is moved down into cooperative relation with the filled. can so that any floating contents in the can is pressed down into the liquid content of the can, thus causing an overflowing if the can is too full.

The pad works in a well known way and the invention is directed more particularly to a means for actuating the pad. There is only one pad in the machine. This pad is secured to a short shaft 9 by means of clamping screws 10-10 which clamp the sleeve of the pad onto the end of the shaft. The mechavi, r

nism for supporting and operating the pad is carried by a casing. 11. which is formed a part. of the bracket 12 secured to the machine by'suitable means 13-13, see Fig. 1.

Located in'this: casing 1:1; is arotated sup-V, port 1.4 Which as shown in. the. drawings is in the form of a gear Wheel. This gear or support is mounted on short stub shaft I5 which is in turn mounted in the casing 11. Secured to the, rear side of the support or gear-l4 is a V sprocket Wheel 16. This sprocket Wheel is driven by a sprocket chain 17wl1ich runs over .a sprocket heel 18 on a short shaft 19 car ried in a housing 20', wh ch is securedto the table Qsupporting thedruin; This shaft 19' also carries asprocket wheel 21 and asproeket 7 chain 22 runs over this sprocket Wheel 21 and also over a sprocket wheel on the cross shaft 23. The cross shaft 23 carries a beveled gear 24 which meshes with a beveled gear 25 on thee'nd of" the shaft The cross shaft 23 therefore becomes a common driving means for the drum lz'and for the pad actuating mechanism. It is by this means that the pad is driven in proper" t'iming with the drum.

The gear 14 meshes with a gear 26 carried by a cross shaft 27 I mounted in suitable bearings in the casing 11. This cross shaft carries a gear 28' which is of'the same diameter as the gear 26; V I

The shaft 9 carrying the packing pad is 'mounted in a rotatable disk or support 30' as the same timing. and have a'one-to-one mo ti on; r l

On the end of" the shaft- 9 there is a de pending crank 321' This depending crank is rigidly connectedto the shaft 9; Mounted on the gear'or support 145 is a stud 33. This stud carries a' rectangular block 3 lrwliich is free to urn on the stud. There'ctangular block 34 is lo cated inthegforked end 35 of the crank 3211 his the-support 30 r(- -tates, t-he shaft 9' will bodily travel about the center of the support and this \villlfgive the pad a bodily iZl'TEl'VGl in air upright circular path. The timing ofthis p ad issuch that the pad will move down into proper cooperative relation with the can.

her on the under face thereof which is'o f substantially the same diameter as the can, and this pro ecting portion mov ng intothe can will depress the floating contents of the can 7 and: if the can is too full will bri about a slight overflowing of; the same. The pad avels in a counter-clockwise direction as edin Fig.1, and the can moves from left to right. Therefore, the pad will come down into the can for a moment and move along with it and then he lifted from the can.

In order to maintain the pad in ahorizontalpositiomi havev provided the crank arm 32 which has been referred to above. The rotating support 30 is eccentrically set relatively to the gear wheellft'. The stud 38 engaging the crank arm and moving in the same timing as thesupporting shaft 9 for the pad will keep the pad in horizontal position. The

stud maintains the crank 32in a vertical posi-.

tion throughout the entire rotation of the sup port tor the pad, and this, of course, keeps thepad in horizontal position. I

From the above it Will be apparent that I have provided a device wherein the means for moving the pad is a positively operating means, operating intiming with the means which cause the bodily travel of the which the pad cooperates.

' It will also'be apparent that I haveprocans with.

vided a positively operating membermovin-g tion, becomes the driving'ineans for the support for the pad, and the only additional means for drivingand maintaining the pad in horizontal position is the cross shaft, which transmits the motion of' the disk or gear wheel which maintains the pad horizontal to the traveling support which moves the pad bodily in its circular path'of travel;

It is obvious that minor changes in the details of construction may be-made without departing from tlie'spirit of the inventionas set forth. in the appended claims. 7

Having thus described my invention, What I desire to cover by'United States Letters Patent, is: r r
