PACKING DEVICE FOR CAN-CLOSING MACHINES.

Application filed November 2, 1917.

The invention relates to new and useful improvements in packing devices for can closing-machines, and more particularly to a device associated with the closing machine and operating to overflow the filled cans prior to the closing of the same.

An object of the invention is to provide a device of the above character wherein a series of pads are brought into operative relation to the filled cans in succession, which pads are mounted so as to travel in a vertical plane and maintain their horizontal position throughout their entire path of travel.

In the drawings Figure 1 is a view, partly in verticalsection and partly in side elevation, showing a portion of a filled can closing machine with my improvements applied thereto;

Fig. 2 is a front view of the same;

Fig. 3 is a diagrammatic view, showing the centers about which the devices travel which support and control the position of the operating pads; and

Fig. 4 is a detail, partly in section, showing the position of the pad when overflowing the can.

The invention is directed particularly to a device associated with a closing machine which operates to depress the floating contents in the filled cans and to uniformly overflow the same so that each can will contain an equal amount of liquid contents. This is accomplished by a series of pads, each of which consists of a projecting part adapted to project into the filled can when the pad is seated against the open end thereof, and thus cause an overflowing of the liquid contents of the can to the desired amount. Each of these pads are mounted so as to travel bodily in a vertical plane and they are also connected to a-c01111110l1 rotating device which is so disposed relative to the arrier for the pads that the pads are maintained in horizontal position throughout their ent1re path of travel.

Specification of Letters Patent.

Patented June 1.7, 1919.

Serial 110,199,888.

While my improved device is especiallv adapted for overflowing the filled cans prior to the closing of the same, it will be understood that it may be used for other purposes, such as the seating of the can end in the can body, in which case the seating pads engage the can ends placed on the top of the can bodies and press the same into the open end of the can, thus seating the ends or covers in the cans.

Referring more in detail to the drawingsz- My improved device is shown as applied to a closing machine having a frame 1 on which is mounted a rotating drum 2v having 'a thread 3 for feeding the filled cans along the supporting table 4. In Fig. l of the drawings, the filled can is indicated in sec tion at 5. Located directly above the support 4 is my improved overflowing device, which mcludes a series of pads 6. These pads are pivotally mounted on a carrier 7.

The carrier 7 is in the form of a disk having a hub 8 which is journaled on a pin 9. The

pin 9 is seated in a bracket 10. Each pad 6 1s clamped to a short shaft 11 by means of a clamping bolt 12 which passes through a split sleeve 13 formed integral with the pad 6. Each shaft 11 is formed with a crank arm 14. The free end of each crank arm is 'journaledin a bearing in a rotating plate 15.

beveled gear 17 which meshes with a pinion 18 on the shaft 19. The shaft 19 extends through a bearing in the bracket 10 and also through a bearing 20 in a bracket 21. The brackets 10 and 21 are clamped to the frame 1 by suitable bolts. Secured to the lower end of the shaft 19 is a hub 22 which carries a sprocket wheel 23. A sprocket chain, shown in dotted lines at 24 in Fig. 2, en gages the sprocket wheel 23 and also a sprocket wheel on one of the operating shafts of the closing machine so that the shaft 19 is rotated in time with the parts of the closing machine, and particularly the feeding drum 2. 7

As this shaft 19 rotates, it will cause the plate 15 to rotate, and as the plate 15 rotates it will operate through the cranks 14 to turn the carrier'T. The carrier 7, as above noted, is pivotally mounted on the pin 9 which is eccentrically set relative to the center of rotation of the plate 15. The center of the pin 9 and the center of this plate 15 are so disposed relative to each other and the links of the crank arms 14 that, as the carrier 7 rotates through the action of the rotation of the plate 15, the pads 6 will be maintained in horizontal position. In other words, these pads 6 travel bodily in a vertical plane, but each pad maintains a horizontal position throughout the entire extent of its travel.

Attached to each pad is a projection 25. The projection is secured to the pad 6 by a bolt 26. The projection 25 is adapted to extend into the body of the can, while the pad comes down against the flange of the can body, or very close thereto, and this causes an overflowing of the liquid contents of the can, forcing the solid floating contents, if there be any, down into the body of the liquid. This causes each can to have a uniform amount of liquid contents.

As above noted, my rotating pads may be used for seating a can end in a can body, in

which case the can ends are fed onto the can bodies and the pads are shaped so as to engage the outer face of the can end and crowd the same into the can body. The timing of the pads is such relative to the conveyer that the pads move into the can bodies one after another without retarding the movements of the can bodies as they are fed to the closing machine by the conveyor.

It is obvious that minor changes in the de tails of construction and the arrangement of parts may be made without departing from the spirit of this invention, as set forth in the appended claims.

Having thus described the invention, what is claimed as new is 1. A packing device for can closing machines. including in combination, a support rotating in a vertical plane, a plurality of pads pivotally carried thereby and moving bodily therewith, and a rotating member with which each pad is pivotally connected, said rotating member being so disposed relative to the support as to maintain said pads in horizontal position during their entire travel.

2. The combination of a rotating support mounted to rotate in a vertical plane, a plurality of pads pivotally carried thereby and moving bodily therewith, a crank arm connected to each pad, and a rotating member connected to the crank arms for rotating the carrier, said rotating member being so disposed relative to the rotating carrier as to maintain said pads in horizontal position throughout their entire travel.

8. The combination with a conveyer for conveying filled cans, of a carrier disposed at one side of the path of travel of the cans and adapted to rotate in a vertical plane,

a plurality of pads extending laterally from the carrier and spaced equally about the center of the carrier, means connected with the pads for rotating the carrier and for maintaining said pads in a horizontal position, said carrier being so disposed relative to the cans and timed relative to the conveyer as to cause the pads to engage the cans in succession one after the other.

4. The combination with a conveyer, of a bracket, a carrier mounted to rotate in a vertical plane on said bracket, a series of pads, a supporting shaft for each pad journaled in the carrier, said shafts being angularly spaced about the center of the carrier, a crank arm for each shaft, a rotating plate set eccentrically relative to the carrier and engaging each crank arm for rotating the carrier and maintaining the pads in horizontal position throughout their entire path of travel, and means for rotating said plate.

In testimony whereof I affix my signature in the presence of a witness.
