CAN-SEALING APPARATUS.

Specification of Letters Patent. Patented Sept. 1'7,

Application filed March 21, 1918. Serial No. 223,735.

To all whom it may concern:

Be it known that I, RUPERT R. SmLnY, a citizen of the United States, residing at Atlanta, in the county of Fulton and State of Georgia, have invented certain new and useful Improvements in Can-Sealing 'Apparatus, of which the following is a specification.

This invention relates to a machine or an apparatus adapted for use in sealing cans and more particularly of the small portable type suitable for home use.

One of the objects of the present invention is to provide a simple and practical can sealing machine 01 apparatus of light portable construction which may be easily operated for sealing cans of a certain typenot requiring the use of solder. A further object is to provide an apparatus of the above general character suitable for home use and capable of various adjustments and having interchangeable parts whereby cans of different sizesmay be operated upon. A further object is to provide a machine of the above general character, having relatively few parts whichma-y be inexpensively manufacand assembled and which will not be likely to get out oforder when in use.

provide a machine of the ciently operating upon the cans of that type having interlocking flange features.

Other objects will be in part obvious from the annexed drawings and in part indicated in connection therewith by the following analysis of this invention. A This invention accordingly consists in the features of construction, parts and in combination of the unique relations of the members and in the relative proportioning and disposition thereof, all as more completely outlined herein.

M to comprehend r "the numerous modifications in structure and To enable others skilled in the art so fully the underlying features thereof that they may embody the same by relation contemplated by this invention, drawings depicting a preferred form have been annexed as a part of this disclosure, and in such drawings like characters of reference denote corresponding parts throughout all the views, in which Figure 1 is a side elevational view of the complete machine;

'Fig. 2 is a detall plan view showing the be understood The present invention is. designed more particularly as. an improvement over that form of device shown in my co-pending application, Serial Number 195,378, filed October 8, 1917, for'can seaming machines.

Referring now to the drawings in detail,

5 denotes any suitable form of base member means whereby it may be securely anchored or fixed in relative position'as upon a table, for example, and from which base project two uprights 6 and 7 having a fitting 8 at the upper end secured thereto by meansof set screws 10 for" holding the same in fixed and adjusted position. This fitting is proadapted ,to be provided with fastening' vided wlth a laterally extending arm 11 in which is mounted a shaft 12 adapted to be rotated in any desired manner by means of handle 13. V

Interposed between the base and fitting 8 is a second fitting or member 14 embracing both rods or supports 6 and 7 and split at one side whereby the same may be clamped in adjusted position by means of set screws or clamping means 15 which when tightened will gripthe rod6 and hold the part in any desired vertically adjusted position.

Thisfitting 1 1 carries a laterally extending arm 16 similar to the arm 11 and is provided at its outer end with a shaft 17 carry ing a table 18 for supporting the can while being sealed or seamed. It is, of course, to

that this table 18 is interchangeably connected with the shaft 17 in any desired manner for supporting cans of different; size. Mounted upon the'shaft 17 is a leverl 20 having a cam member2l adapted to coact with afixed cam member 22 upon the arm 16in such a manner that as the handle or lever 20 is given a quarter turn -the cam surfaces 21 will rideupwardly upon the cam surface 22 thereby moving the table 18 relatively upwardly to bringthe can into sealingfposition as will hereinafterfully be explainedff q V I The lower part of the shaft 12 is provided with a disk 23 which may be easily and quickly separated from the shaft 12 in any desired manner as will appear obvious to those skilled in the art and the disks of larger or smaller size substituted therefor according to the size of the can to be operated upon. The cans and their covers are preferably of that type illustrated in my above referred to pending application in which the cover member is provided with a depressed central portion adapted to be engaged by the disk 23 and forced clownwardly into position within the container when the table is raised. Both the container and cover are provided with registering flanges which are engaged by the seaming or sealing mechanism now about to be describedandto be folded over one upon the other and pressed down into firm interlocking engagement.

This seaming orsealing mechanism is preferably carried by a fitting 25 mounted upon the fixed supports 6 and 7 and connected by means of an adjusting device 26 whereby it may be adjusted vertically upon the supports to any desired degree to pernnt proper alinement of the coacting sealing rollers with disk 23. This member 25 is provided with a laterally extending arm 27 having at its end a guide 28 upon which is adjustably mounted a block 30 adapted to be held in any desired adjusted position by means of bolts or fastening devices 31. The block 31 has a central pivot 32 supporting a segment 33 having gear teeth 34: upon one side thereof adapted to be engaged by a worm gear 35 rotatable in any suitable way as by means of hand wheel 36 extending to one side of the block 31. It will thus be seen that as the wheel 36 is turned, the segment 35 will be rotated either in one direction or the other about the pivot 32 to bring rollers 37 and 38 into or out of'engagement with the disk 23. These rollers and disk are substantially the same as illustrated and described in my above referred to application and are provided with coacting flanges and recesses whereby as the handle 13 is turned the can carried by the disk 23 will also be rotated and the flanges of the cover and can will first be crimped or rolled one upon the other by the roller 38 after which the rolled portion will be firmly pressed down by means of the roller 37.

It is believed from the above description that the operation of this machine will be clearly understood. It may be stated, however, that in operation the disk 23 and table 18 are selected according to the size of the can to be operated upon and put in can is then placed upon the table 18, assuming the necessary vertical adjustments to havebeen made, and the cover applied after place 7 upon the respective shafts l2. and '17. The

which the lever 20 is given a quarter turn to cause a relative upward movement of the table 18, thus pressing the cover firmly into place. The hand wheel 36 is then turned to bring the roller 38 into engagement with or tangential to the disk 23. With the parts in this position, the operator then turns the crank 13 one or more times as may be necessary to insure the engaging flanges of the cover and body member to be rolled into position after which the hand wheel 36is then turned in the opposite direction to bring the roller 37 into engagement with the rolled or turned over flanges, whereupon the crank 13 is given another turn thereby to firmly press down the rolled over flanges of the cover and body portion of the can. After this operation the lever 20 is moved in the opposite direction which causes a relative downward movement of the table and permits the removal of the can therefrom and the insertion of the next can to be operated upon.

It is, of course, to be understood that different size tables ordisks 23 are substituted as may be necessary according to different sizes of cans and when this occurs, it'is frequently necessary to make proper adjustments in the relative distance between the table 20 and disk 23. This is most easily accomplished by loosening the single adjusting device 15 which permits the table 18 and associated parts to be moved the desireddistance.

It will be seen from the above description that the present invention comprises a simple and practical can seaming or sealingapparatus of'light portable construction which renders it particularly adapted for home use. The parts composing the apparatus are relatively few in number and may be easily and inexpensively manufactured and assembled. In short, the invention is believed to accomplish, among others, all of the objects and advantages herein set forth.

I realize that considerable variatibnispossible in the details of construction and arrangement of parts without departing from the spirit of'my invention, and I therefore do not intend to limit myself to the specific form shown and described.

Having thus described my invention what I claim as new and desire to secure-by Letand hand mechanism for bringing one or the other of said seaming rollers into operation at will.
