CAN-END-LINING MACHINE.

Specification of Letters Patent.

Patented Sept. 6, 1921.

To all whom it may 00mm.-

Be it known that 1, CHARLES lV. GRAHAM,

tainer for facility in handling and transporting.

This invention comprises a continuously moving conveyer, built up of a series of members adapted to pass successively under a can end feed chute or stack, where a single can end is deposited into an orifice in the conveyer member, and then to pass directly under a chute or stack of previously out can end liners, and receive a single can end liner in the same orifice but superposed in spaced alinement with the previously placed can end, to then pass under or adjacent second continuously moving member carrying assembling devices that aline with the aforesaidorifices and enter the same, and thereby move the can end liner'toward the can end and cause it to be deposited on the flange of the can end, to then pass to a point of discharge where the lined can end is ejected fromthe machine.

A principal object of the invention lies in the production of a full automatic machine having continuous uninterrupted motion of the lining mechanism, whereby all of ca movement of the mechanism is utilized in useful work, in contradistmction to intermittently operated machines where the mechanism is interrupted and some time thereby lost, thereby giving a greatly increased output with a normal speed of operation. I have illustrated in the drawings attached hereto the invention applied to a multiple machine, which arrangement conduees to a high capacity output with a very slow speed of operation, and thereby greatly enhances the facility 01" operation and inspection.

Another principal object of the invention resides in so designing and constructing a continuous can end lining machine that practically all of the operating mechanism is accessible, thereby enabling an operator to easily see and observe the operation of the machine.

Another object of the invention resides in the manner of depositing the can ends and liners in a recess and holding them in separated assembling relation while bringing them into the zone of assembling mechanism where the liner is deposited on the flange of the can end the two being held in positive alinement during this operation.

I The drawings illustrate a multiple machine but it is readily seen that a single unit embodying one third of the machine would constitute a machine having every facility for automatically applying liners to can ends, having a somewhat lower capacity but none the less efficient.

A framework 1 carries the entire operating mechanism; a drive shaft 2 is mounted sprockets 3 which in turn carry one each of the continuous conveyers 4; the'outer endsv of the shaft 2 carry the drive pulley 5 and gear 6, which'gear'meshes with and drives a gear 7 mounted on a'shaft 8, carrying sprockets 9 which in turn support and drive the assembling conveyer 10. The opposite end of the conveyer4 is supported bya shaft 11 and sprockets12, and the opposite end of:

the assembling conveyer 10 is carried by a shaft 13 and sprockets 14.

Located over the conveyers 4, is a plate'15 carry ng can. end feed stack holders 16 having automatic separating and discharging :mechanism, and also carrying can end liner feed stack holders 17'. The conveyer 4 is made 11 a of orificed link-blocks 18' shown in detail. in Figs. 17 to 22 and shown in plan, section and side views in Figs. 12, 13 and 14 and in open and closed'plan views in Fig.

6 and in linked relation in Fig. 4.

Each member 18 has an orifice 19 in its top flat face, partly covered by shouldered slidable jaws 20 and 21. These jaws are opened and closedjatpredetermined intervals by 1 means of rollers 22 carried by the. jaws, ridare closed laterally against each other and move along underneath a can end'liner stack, and there, automatically receive in their up- .per part above said can end a liner from the stack and hold it in spaced relation to the can end, to move whileboth'are so held to assembling means where the liner and end are assembled as a complete unit.

The oppositely sliding jaws 20 and 21 are provided with shouldered recesses 24 of a diameter and depth just sufficient to admit one can end liner as they pass under the liner stack, the topsare flat and smooth so as to offer no obstruction to the proper feeding of a single liner as they pass under the liner stack. The link members18 are guided in a direct linear path by means of the guides 18 riding in suitable grooves 25in thebed of the machine. These elements hold every link member 18 in perfect alinement with the various cooperating parts as theymove along. j f1 7 The assembling means consists of a con tinuously moving block conveyer running parallel with the aforementioned .conveyer 4, andat the same linear speed and so timed and adjusted that the assembling elements enter the orifices ofthe'conveyer'members 1'8 1 and assemblethe liner with the canend while both conveyors are moving continuously and uniformly.

The can end feed arrangement is illustrated in Figs. 7, 8, 9, 10 and 11 and isoperated by the movement of the conveyer 4. The

rollers 22 in. riding through the cam track 28 contact with a roller 26 on a feed lever 27, moving it outward as shown in Fig. 7, against. the pull of the spring 28. 7 7

There are four rocker members, 29, 30, 31 and 32, arranged in equidistant; relation ped slightly around the can end stack; they are all connected together with combined link and separating members 33, 34, 35 and 36, each carrying knife edge projections 33, 34, 35 and 36, adapted to move alternately, in pairs, into and out of engagement with the can ends during their movement. The rocker lever 29 is connected to the feed lever 27 by a link 37.

In the operation of this automatic feed, the stack of can ends is always supported by one pair or the. other of the pairs of separating members, and by their alternate movement and stepped relation, feed or discharge a single can end from the bottom of the stack at each completed alternation. The two members 34 and 36 form a pairand the members 33 and 35 form the alternate pair. The knife edge projections 34 and 36 are stepped above the projections 38' and 35 the thickness of one can end and by their alternate movement into and out of the vertical zone of the stack operate to separate and discharge a single can end at each cycle. The timing is such that the can end is dropin advance of the approach of the orificed member 18 into vertical alinement with the stack of can ends, so that the discharged can end will be released and ready to drop into the orifice as it reaches the proper position.

The operation of the machine is as follows: The stack chutes 16 are filled with can ends and the stack chutes 17 are filled with previously formed can end liners. By reference to Figs. 17 to 22 it is readily seen just how the sequence of operations takes place and by reference to Fig. 4 the general location of the different stations are easily comprehended. As the machine starts, a conveyer member approaches the can end stack and as the rollers 22 enter the cam grooves 23 they aredeflected outward from their normal linear direction (Figs. 6 and 17), contacting with the rollers 26 on the feed levers 27 causing a movement of the can end feed mechanism that separates and drops a single can end into the orifice of the member 18; this outward movement of the rollers 22 also opens the jaws 20 and 21, thereby permitting the can end to pass down into the orifice 19. It is necessary to open 1 the jaws 20 and 21 at this point, since the recessed opening of the aws, when they are closed, would not permit a can end to pass through. This recessed opening has the said shoulder 24 to support the liner until it is assembled with the can end and the diameter of the opening through the shouldered portion is substantially the same as the diameter of the opening in the flange of the can end produced by the curled edge of the flange. This shoulder 24 acts as a guide for the liner and as a guard over the edge of the curl on the can end, and forms a positive guiding channel that leads the liner over the shoulder of the can end and onto the flange thereof during the assembling operation.

In Fig. 17 a link member is just passing under a can end feed chute, a roller 22 has contacted with a roller 26 on a lever 27 of the can end feed mechanism, operating the same to separate and drop a single can end (the can end as released being shown by dotted lines) so it will pass into the orifice 19. During the continued movement of the link members 18 the jaws 20 and 21 are closed over the deposited can end; this position is well shown in Fig. 18. This view also shows very clearly the recess and shoulder 24 and the can end resting in the orifice with the curled edge covered by the shoulder 24. The member 18 now moves along underneath the liner stack holder 17 and a liner falls into the recess, as shown by Fig. 19, and rests on the shoulder 24 in axial alinement and spaced relation with the can end in the orifice. The liner in the recess 24 is separated from the stack simply by sliding therefrom in being carried along by the member 18. From now on until the lined ends are discharged the jaws 20 and 21 remain closed and during the assembling of the can end and liner are held locked in closed position by the cam grooves 23. The assembling conveyer 10 is composed of link blocks shown in detail in Figs. 15 and 16. Each link block carries an orifice 38 extending into a ring or annular assembling member 37, the orifice 38 being or a diameter to freely pass over the shoulder of the can end,

and the assembling member 37 having an outer diameter to freely pass through the opening formed by the shoulder 24 of the jaws 20 and 21. By reference to Fig. 4 will be seen a fixed cam rail 39, under which the assembling conveyer 10 passes as it moves in unison with the conveyer 4, having a deflecting face 40 against which rollers on the links ride and thereby carry the assembling members 37 down into the orifices of the members 18. Fig. 20 is taken at a point where the assembling member 37 is just approaching the orifice 19 and is just contacting with the liner resting in the recess 24 on the shoulder 24. A further movement for ward of the two conveyors movin flin unison, causes the assembling member 31 to gradually pass down into the orifice 19 and thereby force the liner past the shoulder 24 as shown in Fig. 21 and deposit it around the shoulder of the can end into the recess, channel, annular groove or space formed by the shoulder and the curled edge of the can end as shown by Fig. 22.

The assembling operation being completed, further movement ofthe conveyers 4 and 10 causes the member 37 to gradually rise out of the orifice 19 while the conveyer orifice 19 down around the sprocket 3 to a lcarries-the lined can end confined in the discharge station provided by the frame member 40', Fig. 4, where camways 41, F 1g.

23, engage the rollers 22 of the jaws 20 and 21 and cause the jaws to open thereby releasing the lined can end and permitting it to drop onto the discharge belt 42, which carries it to a receiving boX or receptacle, not shown. The conveyor 4:2 is operated from a gear wheel l on a shaft 2. 7

It is easily seen that a continuous and uni formmovementoi' the conveyers 4 and 10 at a very comfortable speed will give a very high capacity and produce a practically noiseless assembling operation.

It is believed this is the first, instance in the operation of an automatic can end lining machine wherein a continuously movable conveyer memberreccives a can end from a supply of previously formed can ends, then receives a can end liner-from a. supply of previously formed can 'end liners, holding them in spaced relation and axial alinement and carries them so positioned to continuously moving assembling mechanism where the liner and can end are assembled as a complete unit, while the parts have continuous transportingmovement.

' While I have preferred to show my invention as applied, toa multiple machine, I do not wish to confine it to such construction as itis equally well adapted to be applied to asimple construction embodying a, single.

conveyor, continuously moving, for receiving can ends and liners, and holding them in assembling position while passing into the zone ofassembling mechanism that automatically assembles them into a single unit. The can end feed mechanism shown and described is not apart of this invention but is being covered in a separate application.
