momma r012. FILLING AND CLOSING cans. 1 j

To all whom it may come m:

Be it known that I, \VILLIAM E. TAYLOR, a citizen of the United States, residing at East Orange, in the county of Essex and State-of New Jersey, have invented certain new and useful Improvements in Machines for Filling and Closing Cans, of which the following is a specification.

This invention relates to improvements in can filling devices, which are or'may be employed in a machine for applying heads to can bodies, the same being a divisionof my application Serial No. 660,814, filed Nov. 17,

overcoming the difficulties mentioned above,

' has been devised, in which the solder is first fused to the flange of either the cover or the body before the cover is placed on the body,

and then by applying heat, substantially fusing the two flanges together. And in this process it has been found desirable to fuse the two flanges together progressively. point by point in order to allow for the escape of gases produced or the expansion of the air within the can body incident to the heat from the heating or fusing device.

' This latter process has not proven entirely successful, and many cans are produced that develop pin holes and leaks, which are due,

as I have demonstrated by experiment, .to the fact that after the cover and body flanges have been'fused together, and while the solder is setting or cooling, the flanges tend to separate, which separation is caused partly by the contraction of the metal and partly by the inherent springiness of the metal which is not entirely eliminated by the fusing or sweating operation. To prevent this springing or spreading apart of the. flanges, the covers and bodies have been made with one of the flanges wider than that of the other, and the wider flange has been Specification of Letters Patent.

application fl le'd tucked or folded or bent around the nartightly compressed in order to remove all puckers, irregularities and springiness from the metal, and to produce a close contact between each of the folds of the seam, and then the solder is subsequently-fused. On

rower one, the seam thus formed being then account of the mechanical union of the flanges, due to the one being folded over or about the other and firmly compressed together, it becomes almost impossible for the flanges to, warp or spring apart during the.

cooling of the solder, and in this way, a

much better and more perfect can is proautomatically fromthe time thefilled can body is presented to the machine until the can body with its cover applied, tucked and fused thereto, is ejected from themachine- My invention relates more particularly to that class of cans used in packing sardines, wherein the can body is generally of rectangular shape, and wherein the body is filled with the sardines before the same is present- A ed to the oiling and head applying machine. Another object of my invention is to so construct the machine that I automatically supply a definite quantity of oil to each of the cans as they are successively fed along the bed of the machine, and wherein this oil measuring and feeding device is operated only when the can, filled with fish, is presented. By combining this oil measuring and feeding device with the head applying machine, I thereby. greatly reduce the space 1 which has hitherto been necessary in factories where the oil supplying force has been separated from the other; mechanism, and also thereby eliminate one of theoperators necessary tohandle the cans their travel through thefactory. In feeding the cans f.

to the tucking mechanism and during the tucking operation, it is preferable that the cans be fed intermittently, or that they have a period of rest whilethe tucking operation is being performed. During the fusing or sweating operation, it is preferred that the cans be continuously moved, and another object of my invention is to provide means,

of transferring the can with the tucked head the machine or other set of operating mech-- anism is allowed to continue in operation.

My invention consists, therefore, in a machine comprising a suitable bed or frame adapted to support the various mechanisms, and an intermittently operating endless conveyer for feeding the cans to the oil measuring and feeding device, ahead feeding device, a tucking mechanism, means for transferring the can body, with the head tucked thereon and filled with oil, to a continuously operating endless conveyer which feeds the can bodies and the heads thereto to a pressure device for squeezing the tucked seam, and subsequently to a fusing or heating device which fuses the solder. between the flanges.

My invention consists in the improvements of various parts and devices and combinations of parts and devices herein shown, described and claimed.

In the drawings forming a part of this specification, Fig. 1 represents a plan view of the entire machine embodying my improvements.

My machine embodies two sets of operating devices which are arranged in duplicate and operate from the same power shaft, and inasmuch as the various mechanisms in each of the sets are substantially identical, I will only describe the mechanisms of one set or half of the machine.

In the drawing, the frame of the machine is represented by the reference 20; the oil 95 mechanisms by A-A; the endless, intermittently operating conveyers by D-D; the head feeding devices by 13-15; the tucking mechanisms by CC; the mechanisms for transferring the bodies from the intermittently operating conveyer to the continuously operating conveyer by HH; the pressure rollers by EE; the fusing or heating rollers by F -F and the continuously operating die block, chains or conveyers by The frame 20 is provided with a bed portion 21 at the front end thereof,,upon which the can bodies, filled with sardines, are placed by the operator or are conveyed 110 thereto by a belt from the packing tables. The can bodies are then engaged by the fingers or flights 22 on the endless conveyer,

D, which travels around gears 99, and are pushed thereby to a position beneath the oil measuring and feeding device A. This conveyer D is so arranged that it comes to rest while the can body, engaged by one of the fingers 22, is under the oil measuring and feeding device A. This oil feeding mechanism comprises a casing 23, keyed or pinned to a stationary stud shaft 24 attached to the bed 21 by any suitable means, such as the To the lower part of this casing 23 is attached an annular ring plate 25 by means of screws 26. Rotatably mounted on the shaft 24 is a hub 27, having formed integrally therewith adisk 28 adapted to have a sliding fit between the casing 23 and the annular plate 25. The 0 disk 28 is provided with aplurality of recesses 29 equally spaced therearound and eachadapted to in turn register beneath an inlet opening 30 the casing 23, whichopening 30 is in communication'with a supply tank, not shown, by. means of a pipe 31. The annular ring plate 25 is provided with an opening 32, preferably diametrically disof the can body engages the flange of the can head and pulls; the lowermost edge cof' the can head with it. And in order to prevent the can head from becoming displaced" posed to the inlet opening 130, which openng 32 is above the line of travel of the can odies. Each of the opgnin 28 is preferably somewhat elongated, in order that there may be plenty of time during the rotation of the disk, for the oil to flow therein from the inlet opening 30, and these openings 29 are made of the required size to hold the requisite amount of oil neces ,sary to completelyfill the can bodies as they are presented to the oil device. In order to feed the oil to the cans at the proper time, and to insure that such feeding may take place only when a can body is under'the out let hole 32, I form rigidly with the hub 27 acan bodies are next passed under the fluxing rollers 120121'and then the can head feed chute B. The means for feeding the heads B comprises preferably two upright standards 34 having ribs 35, and plates 36 attached thereto to form grooves for the can heads. Each of the uprights 34 is also preferably providedwith a rearwardly extend ing portion 341 adapted to guide the can head -and can body while the former is being applied to the latter. Thecan heads feed by gravity and the lowermost one rests upon projections 37, which are so located as to allow the lowermostedge'of'the lowest can head toengage with theflange of the can rhody as the latter is passed beneath the head chute. As the can body is advanced by the endless conveyer D, the flange on one end or from dropping out of the lowermost part of the chute. I have arranged spring pressed fingers38 on each side of the chute, which engage the can heads at a point preferably slightly below the center thereof. As the can head is taken forward,-it engages the spring pressed fingers 38' and .pushes them out of the way, and the can head then drops down upon the can body and is pressed 29 in the disk firmly thereon by means of the pressure shoe 39. In orderto prevent the can heads from A falling after they are past the spring pressed fingers 38, I provide a spring arm 40, at tached to one of the uprights and having a curved lower end 41. By using the head feedingmechanism above, described, it will be apparent that the, feeding depends entirely uponthe presence of the can body, as does the feeding of the oil to the cans.

From the. head feeding device, can bodiesare next taken to the tucking or folding or crimping mechanism C. This crimping mechanism may be constructed in variousways, but I have'shown the same as comprising anupper cam member 42, having depending flange portions 43, provided with recesses or grooves 44 within which are adjustably mounted the earns, 45. Each of these ca'ms has therein a diagonally disposed slot 46 and is adjustably mounted in the cam plate 42 by means of the bolts 47 and 48. This-cam plate 42 is oscillated on the hub 50 by means'of an, arm 49 attached to the plate, thehub being rigidly attached to the cross piece 51 of the frame of the machine' Formed rigidly and preferably integrally with this hub 50 is a stationary'plate 510,

having radial slots .52 therein in each of which operates the finger 53 formed integrally with each bending or tucking member 54 which slides in the grooves 55 in theplate 510. Each, of these tucking or bending members 54 is preferably cut away at its upper inner corner, as shown at 56, and is retained in place in the grooves 55 by means of triangular plates 57, attached to the stationary plate 510 by means of screws 58. In order to reduce friction, 1 preferably mount upon the studs or fingers 53 of the bending members, rollers 59 which operate in the slots 46 of' the cam member. Rigidly attached to the lower end of the stationary hub 50 is a plate 60 adapted to fit the can head,'and I also pro vide an ejector 61 for ejecting the can from the tucking or crimping head after the bending members 54 are withdrawn. Each of the bending members 54 is provided with a flange engaging portion 62 which cooperates. with the plate 60 to bend the flange of the cover beneath the flange of the body portion, as

will be best understood from Figs. 12 and 13.

In order to regulate the outward throw of the bending members, I provide the triangular plates 57 with stop shoulders 63 which engage corresponding projections 64 on the bendlng members. I have shown this tucking mechanism as adapted to a rectan gular can in which the bending members are I arranged to operate diagonally upon the work, but it is apparent that this tuc 'ng mechanism may be. adaptedfor other f rms of cans, such as circular or oval cans The cans are fed from the-head feeding chute to a position on top of a plunger 65 POItIOIIS 67 corresponding to the contour of the can body flange, and which raised portions 67 forms a pressure device for the seams while the same are being passed under the pressure roller and the fusing device. The recesses 68 in the links of the chain, which correspond to the shape of the can body being operated upon, preferably have at their inner portion a grid 69 in which is mounted a knockout or ejector 70, which is operated by a stationary cam 71 mounted at the rear end of the machine on a sleeve 72 encasin the shaft 73, which operates the gear w eels 74--74 over which the endless conveyer G, composed of the links 66, passes. The can bodies with the heads thereon and the flanges tucked are first presented by the endless conveyer G to the pressure device E, which preferably consists of a roller 75 mounted in adjustable spring pressed bearings, as shown more clearly in Fig. 17.

From the pressure device the can bodies are next fed or presented to the heating or fusing device F, which preferably consists of a roller 7 6, heated by means of a gas flame on the interior thereof, the gas being supplied bymeans of pipes 77 which enter the roller 76 at each end. The fusing or heating roller 76 is also preferably adj ustably mounted in spring pressed bearings similar to the pressure roller 7 5 and likewise acts as a pressure device during the fusing operation. Each of the rollers 75 and 76 is preferably positively driven by means of gears 78 which are driven from a gear 79 on the shaft 73 by means of a chain 80. I have found by experi ment that it is preferable to rotate the, roller so that the surface speed of the same is slightly different from the speed of travel of the can body, so that a wiping or drawing effect is produced on the seam during the fusing operation, which effect is somewhat analogous to that produced when a soldering iron is drawn or rubbed over a seam.

- In operating upon cans of rectangular cross section, it has been found that the best results are obtained by fusing them diagonally, that is, from one corner to the corner diagonally opposite, in order to allow for the escape of gases formed due to the heat from the fusing or sweating roller, and I I have therefore shown my endless conveyer G with the recess 68, therein so arranged as to present the can bodies as in the manner described;

more particularly shown in Figs. 18 and 19.

As the can bodies are fed forward along the table 21 by the fingers 22 on the conveyer D, they engage a track 81 which deflects the can from its line of travel to a position so arranged that it will readily drop into the holes or recesses 68 of the endless conveyer. This track 81 preferably has a lip 82 thereon adapted to engage the under side of the seam on the can body. Cooperating with thistrack 81 is a similar track 83 having a corresponding ledge 84. The can bodies are pushed along these two tracks 81 and 83 until they engage a spring 85 at a time when the chain or endless conveyer D is at rest, and this spring 85 prevents the can from being carried too far forward by its own momentum. The track 81 at this point is provided with an oscillatory arm 86, having a lower lip .87 in alignment with thelip 82 and on which the seam of the can body is adapted to rest. While the can body is at rest, and while one of the links of the endless conveyer G is approaching a position beneath the can body, the can body is dropped or released by means of the arm 86 being swung outwardly by means of a finger 88 bya cam 89 on the link engaging the roller 90 on theend of the arm 88, and which arm 88 is immediately returned to position bvmeans of a spring 91 attached thereto att one end, and to a stationary part of the frame at its other end. As the arm 86 is swung or operated outwardly, it will be apparent that the can body drops down into the recess 68 through a hole 92 in the bed 21 and that upon the next movement of the chain or conveyer D, another can will be placed upon the ledge 84 and the lip 87 and the process of feeding or transferring the can bodies from the intermittently operate 7 97 keyed thereto andslidable' thereon and adapted to engage a clutch face formed rigid with a gear 98 loosely mounted on the shaft 93. It will be obvious that with the mechanism described, the shaft 93 is continuously rotated and that either of the gears 96 or 98 may be thrown into opera tion, independently of the other, by slid-- forms.

r ing the ulley with its clutch face or the clutch 9'? to engagement with the clutch faces of the gears 96 or 98 as by means of clutch operating levers 196-.

'Each of the endless conveyers G is operated from either the gear 96 or 98 by means of an interposed gear 100, fixed to a shaft 101, and having thereon a sprocket 102 operating the chain 103, which in turn rotates the gear 104, on the shaft 105upon which are mounted two of thesaid conveyer gears 74. Each of these shafts 101 and 105 extends to the middle of the machine but they are formed independently of each other,

5 as are all of the other cross shafts of the machine, except --the 'power shaft :93. Mountedon the shaft 101 is another gear or sprocket 106 over which passes a sprocket chain 107 for rotating the sprocket 108 on the shaft 109. Upon this shaft 109 is mounted a cam 110 which operates the rod 111, which is preferably made adjustable and which is pivotally attached to the plunger 65, as shown in Fig. 3. Mounted on the outer end of each of the shafts 105 are cams 112 engaging .rollers at the lower ends of members 113, pivoted to the frame at 114, the ,upper ends of which members 113 are pivotally connected, preferably by means of an adjustable link to the arm 49' of the cam- 42. Each of the chains or endless conveyers D is operated from a ver-' tical shaft .115 by means of a bevel gear 116 thereon at its lower end which engages a corresponding bevel gear 117 on the cross ,shaft 118, The cross shaft 118 is given an intermittent rotationfrom the shaft 109 by meansof the well known Geneva construction 119. Located between the oil feeding and measuring device and the head or cover feeding device and above the path of travel of the cans, is a fluxing roller 120, preferably mounted in the base members of the feed chute. This roller is preferably a composition roller or one that is'more or less flexible and contacts the upper face of the solder coated flange of the body to flux the same with the .oil used in packing the fish. This oil is fed to the roller by means of over filled cans that pass through the. oiler, the superfluous oil being absorbed by the roller, thereby keeping the same wet.

, Preferably I employ a second roller 121,

located above the flu'xing .roller, the roller 121 being of steel and knurled, wherebythc oil is picked upfrom the flux] roller and spread again, more evenly on the flux .roller.

Although I have described my fnachine as 160 adapted to operate on rectangular c'anbodies and covers, it is apparent that the same may be easily adapted to operate on cans'of other I" have also shown, the machine as adaptedto tuck or clinch or fold the flange '65 of the cover around that of 'the bodybut changes well within the scope of my inven- I tion may be made adapting the same for use with bodies andcovers, in which the body flange is wider than that of thecover, and operating to fold the body flange over that of the cover. -A great many changes may also be made in the different parts and details of my machine, and more particularly in the s ec'ific forms of the tucking mecha-.

nism, th location and form of the intermittently operating conveyer, Elie details of the can body transferring mec anism, the form and type of the seam pressure means and fusing devices and in the form and arrangement of the various driving means for the different parts of the machine, without in any way departing from the spirit of the invention. And-all such changes are contemplated as fairlycome within the scope of the appended claims. 1
