PACKING DEVICE FOR FILLED-CAN-CLOSING MACHINES.

Application filed November 5, 1928. Serial No. 146,444. I

The invention relates to new and useful improvements in packin devices forfilled can closing machines, and more particularly to a packing device which operates to depress the floating content of the can. I

An object of the-invention is to provide device of the, above'charactcr with means whereby any floating content which overlies the flanged edge of the can body may be 3Q cut off, so as-to permit the floating content be forced downinto the can body without leaving any content in engagement with the flange.

I A further object of the invention is to provide a device of the above character, wherein the pad or head which moves down into "the can body for depressing the floating content thereof, is provided with a recess and perforations or openings leading 2Q therefrom to the face of the pad or head, whereby the liquid content of the can body may pass up into the recess and subsequentiy drain back into the can when the pad or head is removed therefrom.

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

in the drawings which show b i lustration one embodiment of t e 30 tion-- Figure 1 is a view part1 in front elevation and partly in section s owing a portion of a closin machine having theimprovements applied thereto; Fig. 2 is an enlarged sectional view through the packing head, also showing the body which is being entered by the packing head, and Fig. 3 is a lower front view of a portion of the packing head.

The invention is directed to a acking device for a filled can closing mac ine, which is so constructed as to depress the floating content of the can rior to the passing of the can body into the closing machine. It has been found in practice, that often some of 'the floating content, particularly in connection with string beans, is likel to overlie the flange on the can body, an when the packing head comes down to depress the floating content, this overlying portion is clamped against the-flange and is not depressed. The overlying portion of the content wiii then go into the closing machine 51% overlying the flange, and when the cover is way of lnvenwhich surrounds t placed, this content works into the double seam and causes a leak. The present invention is directed particularly to the construction of the packing head, whereb means is provided for severing the over tion of the content, so thatremaining in the can into the can body. This is accomplished .by placing on the packing head, a cutter,

e packing head, and so as to move down ying porthe content is. spaced therefrom over the flange of the can body and thus sever any content lying on the flange and extending beyond the same. This packing head is also provided with a recess or chamber and with perforations leadin from the lower face of the pad or head on t e packing device into said recess or chamber. mits the liquid content of the can to pass up into said recess or chamber without overflowing the can, which is quite an advantage, particularly in the putting up of-string beans or similar food products. Of course, when the head is lifted fromthe can-body, the liquid content or brine will drain back into the can.

Referring more in detail to the drawings, I have shown the invention as applied to a closing machine consisting of a main supportingframe 1 carryin a bracket in which is mounted a rotating dicated the support for the can body, and the raised into proper position for the double seaming of the end on to the body by a double seaming mechanism. A cover feeding mechanism is located above this support 3. In the drawings, the can body is in dicated at C. It is about to be moved on to the drum, and the thread 4 will engage behind the can body and move the same along a suitable supporting rail and guide bar to the support 3. These features are all of well-known construction, and it is not thought necessary to define the closing machine more in detail. Attached to this main frame 1 is a bracket 5, and mounted on the bracket '5 is a pad 6 is carried by a supporting shaft 7, which not only rotates, but travels bodily so that this packing pad 6 remains horizontal, but will move in a counter-clockwise direction as viewed in Fig. 1, and will, therefore, come down into the can, move along with the can for'a short distance, and then rise drum 2. At 3 is inmay. be depressed This percan body when placed on this support, is A packing pad 6.. The packing" away from the can. This packing device is similar to that shown in the patent to Fluck No. 1,307 ,248, granted June 17, 1919. In this prior patent, a plural ty of packing pads are shown and described, while in the drawings, only one is shown. The deta l structure for supporting and operating th1s acking device as shown in the drawings, orms the subject-matter of a pending ap lication of George Flock, Serial No. 45,9 86, flled July 24, 1925. The present invention has to do entirely with the construction of the packing device and not to the manner of mounting and operating the same. The

packing device 6 consists of a disk-she ed body portion, on the under face of whic is mounted a cutting disk 8. This cutting disk 8 has a de ending flange 9, the inner edge 10 of whic tached to the under face of this cutting disk is a pad 11. A bolt 12 secures the pad and disk to the packing device 6. This securing means may be of any desired construction. 7

The pad 11 has an annular recess 13 therein and a series of perforations 14 which lead from the face of the pad into the recess. When-this packing device comes'down on to the cam C, the pad will move into the can body, while the cutter will move down outside of the can body close to the flange at the upper end of the can body. Any floating content in the can body wi 1 be engaged by the cutting edge 10 of the cutting device, and severed. This releases the float-.

ing. content so that the pad 11 will readily force the'same down into the liquid content of the can. It is very desirable in some instances, such as packing string beans, to

depress the floating content without overflowingl the can. In the present-construe tion, t e perforations l4 serve as a means for permitting the brine or liquid content of the can body to pass up into the recess 13. Thus it is that the packin down into the can body wit out causing any overflowing of the same. When the pad is raised from the can body, the brine or liquid 7 content in the recess 13 will quickly drain back into the can body. It will be understood, of course, that the'pad 11 does not make an air-tight contact with the under face of the disk 8, and therefore, the air may I escape from the recess 13 permitting the brine to flow into the same.

From the above it will be apparent that 'Ihave provided a packing device which insures that the floating content will be depressed into the can body and drawn off rom the flange so that the flange is freed from-any content all the Wayaround. Furthermore, it insures that the floating content may be depressed without causing any is a sharp cutting ed e. At-

pad may move undue overflowing of the liquid content of.

the can body.

It is obvious that minor changes in the details of construction and the arran ement of the parts may-be made without eparting from the spirit of the invention as set forth in the appended claims.

Having thus described the invention,

what I claim as new and desire to secure by ing flange with a cutting edge at the inner side thereof adapted to move down along the flan e of the can body for cuttin off any ovei iying content in the can, said packing device having a packing pad located within the cutting edge of said disk and spaced therefrom and adapted to move down into the (an body for depressing the floating content.

3. A packing device for closing machines comprising a packing pad adapted to be moved into the can body for depressing the, floating content thereof, and a cutter sur- 7 rounding and spaced from said packing pad adapted to move down over the can body v and out off an content of the can body overlying the ange of the can body, said pad having a recess therein, and openings leading from the lower face of said pad into said recess, whereby the liquid in the can i may pass out into said recess when the pad moves into the can body, and may be drawn back into the can when the pad is raised.

4. packing device for closing machines comprising a cutting disk having a depending flange with a cutting edge at the inner side thereof adapted to move down along thelflange of the can body for cutting oif' any overlying content in the can, said packing device having a packing pad located within the cutting edge of said disk and spaced therefrom and adapted to move down into the can body for depressing the Heat.

ing content, said pad having a recess therein, and openings leading from the lower face of said pad into said recess, whereby the liquid in the can may pass out intosaid recess when the pad moves into the can body,

and may be drawn back into the can when the pad is raised.

In testimony whereof, I aflix my signature.
