IVAN D. THORNBURGH, OF OAKLAND, CALIFORNIA, ASSIGNOR TO AMERICAN CAN COMPANY, OF SAN FRANCISCO, CALIFORNIA, A CORPORATION OF NEW JERSEY.

ORGANIZED APPARATUS FOR APPLYING AND SEALING LINED CAN ENDS TO CAN BODIES.

Application filed August 17,

To all whom it may concern:

Be itknown that I, IVAN D. THORNBURGH, a citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented certain new and useful Improvements in Organized Apparatus for Applying and Sealing Lined Can Ends to Can-Bodies, of which the following is a specification.

The hereinafter described inventlon relates to an organized apparatus for applylng and sealing lined can ends to can bodies, and the invention is designed for use in the assembling and applying of can ends to that type of cans known in the art as sanitary cans, or those wherein the hermetically sealed joint between the can end flange and the flanged ends of the can body is closed or formed by a gasket liner interposed between the flange of the can end and the flanged end wall of the can body.

Of late it has been proposed to preserve food products in that type of cans wherein the entire bottom of the can is removable for the purpose of withdrawing the contents from the container. The can bodies are supplied to the canners with one end, or what shall hereafter be termed the bottom end applied thereto, the top end being left off of the can in order that the canner may place the food products therein to be preserved. 'With this type of can it hasbeen found heretofore impracticable to automatically assemble the gasket lined bottomto the can body, due to the fact that, contrary to the usual practice of applying can ends to can bodies, it is required that instead of the can end being brought down onto the can body, the body must be brought down onto the gasket lined can end. The reason for this is owing to the fact that-in connection with this type of can body, the gasket lined and is a non-curled end, hence, if the can end be placed in an inverted position, the gasket liner will drop or fall from the can .end flan e.

T e present invention therefore resides in an automatic organized apparatus for placing gasket lined can ends and can bodies in axial alined position and preferably with the can body uppermost and held separate and supported a slight distance above the gasket lined can end, with means for conveying the axial alined can body and end to assembling position onto a horizontally Specification of Letters Patent.

disposed, freely rotatable disk, with means for clamping the can body and end to said disk for free rotation, combined with mechanism for uniting the flange of the can end to the can body, and where utilized for the whereby the sealing strip is securely clamped to said parts for holding the same in locked position.

In brief, the apparatus comprises in its preferred embodiment, a reciprocating feed slide for receiving and delivering the can ends into the initial assembling position, combined with a horizontally reciprocating feedslide working in unison therewith and preferably at right angles to the line of travel of the can end feed slide, for bring-- ing can bodies from the feeding mechanism into axial alinement with the can end at the initial assembling station of the appara tus, and means for transferring the axially alined can body and end from the initial assembling station to the assembling station of the apparatus, during such transfer movement the said can body and end moving in unison and the can body being accurately brought downwardly onto the can end, so that when the initial assembling position has been reached, the flanged end of the can body will rest on the flangedend of the can bottom, with mechanism for clamping the can body and bottom so assembled and holding the same in such assembled position for free rotation, and means for uniting the lined can end with the can body, such means as shown herein applying, during the rotary movement of the clamped can body and end, a sealing strip for securely uniting the flange of the can bottom to the flanged end of the can body.

In the apparatus as hereinafter set forth gasket liners are applied to the flange of the can bottom, the gasket liner being either cut from a disk blank of proper sizeor else out from a traveling web of gasket material; in the present case, however, the ring liners are illustrated as being cut from a disk blank, which blanks are fed successively from a stack of' blanks into the pockets ofa rotatable turret and while 'held in said pockets the gasket liner is cut from bottom ends may he fedwithin the sphere of the can end feed slide from a'stack of gasket lined can ends. It will therefore be understood that the invention.contemplates either the cutting of gasket liners from disks of gasket material or from a web of gasket material, and bringing the same into axial alinementwith an unlined can end and applying the gasket liner to the said unlined can end or bottom prior to the same being delivered to the can end feed mechanism, and equally so,,the delivery of a gasket lined can end within thesphere of a can end feed mechanism.

It will be understood in the carrying out of the invention that the various interconnected or assembled working parts of the apparatus are automatic in their operation and work in timed relation one with the other so as to come into action at the proper moment for the carrying out successively of the various steps incident to the operation just descrifoed.

The sea ing strip employed in connection with the closingof the can bottom to the can end is formed of such material as to be easily unwound or removed from the container to permit the sealed can bottom to be readily detached or removed from the container, and in connection with the sealing strip feed mechanism there is embodied means for accurately forming'the same into a U-shape or trough-like form so that when the same is brought into position relative to the assembled can body and bottom, the said strip will embrace the upper surface of the flanged portion of the can body and the lower surface of the flange of the can bottom, so that when pressure is applied to the two surfaces of the sealing strip, the same are firmly pressed onto the flanged surfaces of the can body and can end.

In" order to comprehend the invention, reference should be had to the accompanying sheets of drawings, wherein- Figure 1 is a front elevation of the parts in assembled position, disclosing can bodies being fed into the machine, and the sealing strip being fed to the forming rolls, also disclosing the rotatable turret for conveying gasket liners and can ends to the can end feeding mechanism, and illustrating in general the drive mechanism for the various working parts of the' apparatus and the punch or die mechanism for cutting the ring liners from the gasket material and the assembling plunger for applying the gasket liner to the flange of a can end.

In the drawings, the numeral. 1 is used to designate any suitable form of a frame capable of sustaining the various working parts of the apparatus, which frame in the present case comprises a suitable base plate 2 and upwardly extending frame pieces 3 and 3; a horizontally disposed drive shaft 4 is journaled in suitable bearings 4t supported by the upper end portions of the frame pieces 3 and 3' and the central upwardly extended portions of the frame 1, and the said drive shaft 4 at one end carries the belt pulley 5 to which power is applied in any suitable manner and its opposite end has secured thereto a bevel gear 6, which gear meshes with a similar gear 7 secured to the upper end of a vertically disposed shaft 8, which shaft turns in guide bearings 9 carried by the brackets 9 projected from the frame piece 3, and the said shaft 8 at its shaft 12 through the medium of a Geneva wheel 14, secured to the said shaft 13 and which Geneva wheel 14 is actuated bythe Geneva arm 15 secured to the shaft 12, said Geneva arm 15 carrying at its upper end the roll 15 which works in and out of the radial slots of the Geneva wheel 14, Figs. 1 and 10 of the drawings.

On the outer end of the shaft 13 is secured a miter gear 16, which said gear meshes with a miter gear 17 secured to the lower end portion of the vertical shaft 18, journaled in suitable bearings of the machine, and the said shaft 18 at its upper end has secured thereto a horizontally disposed rotatable turret 19 which rests upon a table 20 secured to the frame of the machine, Figs. 1, 3 and 4' of the drawings.

As will be seen by reference to Fig. 3 of the drawings, the pitman 21 operating on a crank 22 formed in the drive shaft 4 is pivotally connected to a vertical movable slide 23 working within the vertical guide ways formed in the frame piece 23 and' at its lower end the said slide 23 carries a cutting l die 24. The die 24 is surrounded by a stripper ring 25, which stripper ring is normally held in a downward position by means of the springs 26 seated within the die head 24'; a pitman 27 similar to the pitman 21 operating on the crank 28 formed in the shaft 12, is pivotally connected at its free end to a slide 29, which works in guideways formed in the frame iece 29. The said slide 29 at itsupper end carries a cutting die ring 30, which said die ring is arranged in axialalinement with the cutting die 24 and cooperates therewith during the action of cutting a gasket liner from the gasket material fromwhich it is formed. Thesaid cutting ring 30 normally rests within a die opening 30. formed in the table 20.

Said. horizontally rotatable turret 19 is provided circumferentially with a plurality of vertically disposed pockets 31 which pockets are adapted to be successively brought into regist with the die opening 30 of the table 20 an in axial alinement with the cutting dies 24 and 30.

Referring to Figs. 2 and 4 of the drawings,

'it will be noted that there is rovided above the horizontally disposed tab e20 a suitably constructed disk blank holder 32, which is adapted to contain a stack of horizontally disposed disk blanks 33 formed of gasket material, and the said blank holder 32 in the present case is upwardly )rojected from a suitable centrally aperture base plate 34 secured to the upper surface of the table 20 and adjacent to the rotatable turret 19. Associated with the said holder 32 is a reciprocating feed slide 35, which operates in ways 36 of the base plate 34.

The said slide- 35 is rovided at its inner end with a cut-out kni e or blade 38 which, during the inward stroke of the said slide, moves between the lowermost disk of the stack of disks and the disk immediately thereabove and cuts out the said lowermost disk and moves the same inwardly through the radial opening 33 of the turret opening 31, and on its backward stroke leaves the disk blank within said opening and seated on the circumferential shoulder 31. The said slide 35 is actuated by a lever 40 connected thereto by a link 39 at its upper end, the said lever 40 being pivoted at 41 to the base plate 2 of the machine, and the said lever 40 has pivoted thereto, adjacent its lower end, a connecting rod 42. This rod at its inner end is connected to a yoke 43 which carries a camfollower roll 44 op rating or working in a cam groove 45 cut in one face of a vertical cam 46 secured to the horizontal shaft 12. The action of the cam 46 on the slide 35 through the medium of the described connection, advances the said slide toward the turret 19, thereby carrying the knife or cut-out,blade 38 between the two owerinost blanks of the stack of blanks contained within the holder 32 for the removal of the lowermost blank and the po sitioning of the same as described on the circumferential ledge or shoulder 31' formed in the pockets 31 of the turret 19.

At another portion of the horizontally disposed table 20, and preferably opposite that at which is situated the holder for the disk blanks, is located a can end holder 47 which. like the holder for the disk blanks, is upwardly projected from a centrally apertured base plate 48, the said holder 47 being adapted to contain a stack of horizontally disposed can ends 50. The said base plate 48 of the holder 47 is secured to a frame piece 49, supported by the table 20 and brackets 49' projected from the frame of the machine. They can ends are successively removed from within the holder by means of the reciprocating slide 51 which slide is connected by a link 52 to the operating lever 53, which lever is pivoted at 54 to cam inclined portions 59 which on the inward stroke of the said slide 51 act upon the rollers 60 carried by the levers 61, which levers are pivoted at 62-to the frame piece 49, the aid rollers 60.being. held inwardly against he cam surfaces 59 by the tension of the spring 63, which is connected to the outer ends of the pivoted levers 61, Figs. 2 and 5 of the drawings.

At their inner ends the levers 61 carry the inwardly projected adjustable cut-out. plates or fingers 64, which operate or move within the opening 65 cut in the base plate 48 of the can end holder, and the said cut-out plates or fingers are provided-with the incline surfaces 66, so that during the inward movement of the inner end portion of the pivoted levers 61 the said blades move between the two lowermost can ends of the stack of retained ends and separate and cut out the lowermost can end from the said stack of ends contained within the .holder 47, the action of the incline faces of the cutout fingers being to lift the entire body of the stack of can ends with the exception of the lowermost 'end of the stack.

It will clearly be seen by reference to Fig. 1

ret immediately beneath and in axial aline ment with the cut ring liner situated therein. It will be understood that the cutting die mechanism heretofore described and illus- 'trated in Fig. 3 of the drawings is located or situated intermediate of the disk feed mechanism and the ldescribed can end feed mechanism, sothat as the turret 19 is rotated to carry a disk of gasket material from the disk feed station toward the can end feed station, the cutting mechanism comes" into action-at a moment of rest of the rotatable. turret for acting on the disk of gasket material situated within one of the openings of the rotatable turretb'rought into alinement with the cutting dies and severs therefrom' a gasket ring of proper size. The next rotation of the turret 19 places the pocket or opening carrying the ring liner into position besi e the can end feed mechanism, for permitting the can end to be delivered from the-stack of can ends into the said pocket beneath and in axial anism 'or reciprocating slide for conveying the same to the primary assembling station, and in Fig. 2 of the drawings the station at which the disk of gasket material is delivered into one of the pockets of the rotatable turret is designated by the reference letter C, and the station at which the ring liner or gasket liner iscut from, said gasket material at a subsequent stage of the turrets rotation, is designated by the reference letter D, and the station at which the unlined can end is conveyed into "the pocket of the turret beneath and in axial alinement with the cut ring liner, is designated by the reference letter E, and the station at which.

the assembling of. the cut gasket liner relative to the flange of the can end as'pere formed at a subsequent step of the turrets potaltion is designated by the reference let- Referring more particularly atthis point to the feed of the sealing strip and the formation of the said strip for applying same to the flanges of the assembled car. body and end, and which mechanism appears in Figs. 1, 2, 14, 15 and 16 of the drawings, the reference numeral 67 designates a horizontally disposed shaft journaled in bearings of the frame of the machine and held in longitudinal alinement with the horizontally disposed shaft 13, more clearly seen in Fig. 1 of the drawings. The said shaft 67 carries at its inner extremity a cone clutch member 68 which is adapted to move into a recessed wall 69 of a disk clutch member 70, which said member 70 is feathered upon the shaft 13.. Normally, the said disk clutch member 70 is held away from the clutch member 68 by the tension of a sprin the shafts 67 and 13, Figs. 1 and 13 of the drawings. The said disk clutch member 70 is-provided on the periphery thereof with an annular groove 72, which isgnormally positioned in line with a cam disk 73, aflixed to the shaft 12, and the 'saidcam disk 73 is formed on its periphery with a cut-Qut portion 74, which cut-out portion during each revolution of the. disk 73 clears the lower edge of the disk 70 andpermits the same to slide inwardly toward or outwardly away from the cone clutch member68. The function of the said disk 73 is to lock the disk 70 forward or backward, as the case may be, relative to the cone clutch member 68. p

It is the rotation which is transmitted-at proper intervals or in proper timed relation from the shaft 13 to the shaft 67 through the medium of the described clutch mechanism which, in turn, transmits motion to the respective drive means to actuate the feed and forming rolls for the sealing strip,

71, located between the ends ofdrawings, for applying the cut gasket liner to the flange of a positioned unlined can.

end, is situated the assembling mechanism,

and which a pears more clearly in Figs. 1, 7, 8 and-9 of the drawings.

Referring more particularly to Figs. 1 and 9 of the drawings, it will be noted that a cam 75 secured to the up er horizontallywhich is pro-v disposed drive shaft 4, an vided witha cam groove 7 6 in one face thereof,-operates during the rotary movement of the driveshaft 4 upon a cam follower roll 77" secured to the lower extremity of ayoke [78, whichvsaid yoke isconnected .to a rod 79,,the saidrod can'ying at its lower extremity aplunger 80, which is in axial alinement with'one of the pockets 31 of the turret 19 during a rest moment of the said turret,

' the said plunger 80 being held normally above the surface of the rotatable turret 19. This plunger or plunger head is formed with a downwardly'extended annular extremity 80' which, during the downward movement of ,the said plunger, is adaptedto move within the opening 31.0f the turret in axial alinement therewith,iand said plunger head 80 has connected thereto and within the annular projection 80 thereof,-an ejector plate 81 which is held to the plunger head by a stud 82, and the said ejector plate is normally held downwardly away from' pocket 31 of the turret and carries the same downwardly below the said ledge and deposits it onto the flange of the can end contained within said pocket of the turret 19,

" and 8 of the drawings.

Fi s. 1 i '%he moment the gasket liner has been applied to the flange of the can end, the plunger commences its return or upward stroke, but through the action of the springs 83, the ejector or follower 81 by its retarded movement, due to the pressure of the said springs,

holds the lined can end down onto and against the upper face of the horizontally reciprocating slide feed plate 86, which slide plate operates within guide ways 87. formed in the table 20. Inasmuch as the feed slide 86 is provided at its outer end with an upwardly projected shoulder extension 88, the said extension or shoulder will engage the outer circumferential edge of the can end and serve to forcibly push the can end inwardly with the forward stroke of the said feed slide, thereby removing the lined can and from within the sphere of the rotatable turret, and advancing the same to a point a slight distance beyond the said rotatable turret. During this inward stroke of the feed slide the gasket lined can endis moved beneath a retaining spring 88 which exerts a downward pressure on the said lined can end and prevents the same being moved outslide, and on thefull return of the said feed slide, to lower the lined can end onto the face of the table 20 so as to place its outer wall edge in line with the notched'forward end 88 of] the reciprocating feed slide. The gasket dined can. end is thus placed so asto be engaged by the forward notched edge or end 88 of the, feed slide on its next forward stroke to be moved thereby from its position of rest. At this point the gasket lined can end is inaxial alinement with a can body, which has been brought into initial assembling position by means of the hereinafter described mechanism, and it'is held separated from the said can body by asupporting plate on which the said can body rests. It

is from this position that the lined can end and the can body are moved to assembling position by the next forward stroke of the reciprocating feed slide; the notched inner end 88 of the feed slide is at such time engaging the can end and advancing and wardly on the return stroke of the said feed movingthe same onto the lower rotatable in the longitudinally slotted portion 87 of the table 20. The said arm 86 is provided with an angularly disposed overhang exten sion 86 projected inwardly to overlie the reciprocating feed slide 86 and at a height sufliciently above the same to engage with the rear wall surface of a positioned can body 103, a slight distance above the bottom thereof. By means of this construction, as the feed slide 86is moved inwardly to carry a lined can end from the initial assembling station G- to the assembling station H, the overhang extension 86 of the bracket or arm 86 engages the rear wall surface of the can 103, and moving with the slide 86 advances ormoves the can body in unison with the movement of the lined can end, so that the said can end and the can body are brought to a state of rest at the assembling station at one and the same time and in axial al nement.

As shownin Figs. 6. 7, 8 and 10 of the 10 of the drawings.

drawings, the actuating plate 89 to which is attached the can end feed slide 86, is provided on one edge thereof with a rack portion 91, which rack portion of the plate 89 meshes with a gear 92, mounted upon a vertical shaft- 93, journaled in suitable bearingsin the frame of the machine, and the said gear 92 in turn meshes with a segment rack 94 secured to a vertical shaft 95, journaled in suitable bearings in the frame of the machine. In its upper end portion the shaft- 95 is provided with a vertical slot and clutch member 96 (Fig. 10) within which normally fits thetooth portion 97 of the sliding block 97 feathered on the shaft 98, projected at its lower end within the upper eXtremit of the clutch member 96, and which sha t is journaled in suitable bearings of frame 1 of the machine. The tension of a spring 97 normally holds the block 97 in locked engagement with the clutch 96. The shaft 95 is a rock shaft and rocking motion is imparted thereto through the medium of the crank arm 99 secured to the upper end portion of the shaft 98, the said crank arm at its outer end portion carrying a follower roll 100, which works within a cam groove 101 out in the periphery of the disk 102 secured to the horizontal drive shaft 4.

The can body 103 to'which the end or bottom is to be applied is fed into the machineand brought to the station designated by the reference latter A in Fig.2 of the drawings, by means of the endless carrier belt 104,

which belt moves over the table 20 and passes over the idler roll 105, journaled in the under surface of the table, Figs. 2, 6, 7 and The said carrier belt is continuously diven by any suitable mechanism, not shown in the drawings, and adjacent to the said carrier belt 104 at the inner extremity thereof, as shown more clearly in Fig. 2 of the drawings, there is located a horizontally reciprocating feed slide 106, which works in guide ways 107, and in the present case its movement is at right angles to the direction of travel of the reciprocating can end feed slide 86. The said slide 106,

like the slide 86, is provided with a rack tooth portion 108, Fig. 6 of the drawings, which meshes with a gear 109 mounted on a fixed stud 110 upwardly projected from the table 20, and the said gear 109 also meshes with a racksegment 111 which, like the rack segment 94, is secured to and works with the vertical shaft 95.

Atthe inner extremity of the runway for the incoming can bodies 103, is located a transverse wall plate 112, which acts as a stop for the inward moving can bodies and to hold the innermost one thereof at rest in line with the reciprocating slide 106..

When a can body is in this position,- the inward stroke ofjthe slide 106 moves the said can body inwardly transversely, carrying the same from off the endless carrier 104 and depositing the same onto the supporting plate 113 under which the gasket lined can end is brought, so that the can body and the casket lined can end stand in axial alinement,

but separated by the plate 113 which, at such time, supports the can body. During the movement of the can bodies by the endless carrier toward the barrier wall 112, the same move beneath the gage plate 114, which serves to prevent the can bodies from moving out of adjusted position so as'to be held porting plate 113 and serving at the same time to hold the can body in its proper position relative to the gasket lined can end as the said can end and the can body are moved to assembled position on the inward stroke of the reciprocating feed slide 86, the gage plate 118 attached to the bracket 117 serving,

.with the plate 115, to properly guide the can body during its movement to assembling position.

By reference I30 Fig. 10'of the drawings, it will be noted that the hinged guide plate 115 is prevented from moving downwardly beyond a given distance by means of the lip extension 119 projected from the bracket 117.

By reference-to Fig. 2 of the drawings, it will be observed that the runway for the infeed of the can bodiesto the station A. is

formed by the parallel bars 120, which are held above the table 20 by' suitable supporting brackets 121.

Referring now to the feed mechanism for the sealing strip, Figs. 1,2, 14, 15 and 16, it will be noted that the strip of sealing metal which consists of a thin pliable strip 122, is wound upon a spool 123 which is mounted upon a stud 124 which is aflixed to the table 20. This is a continuous sealing strip and is delivered by the feed rolls 125 and 126 to the form rolls. These feed rolls are mounted respectively upon the spaced vertical shafts 127 and 128 which are mounted in suitable journals on the table 20 and are geared to turn in unison by means of the gears 129 and 130 respectively, Fig. 14 of the drawings. The gear 131 which is secured to the lower extremity of the shaft 127meshes with the gear 132 secured to the horizontal shaft 1 o to the shaft The feed rolls 125 and 126 feed and deliver the sealing strip to the first unison by the meshing gears 137 and 138 re-' operation forming rolls 133 and 134, Fig. of the drawings, which forming rolls are mounted respectively upon the shafts 135 and 136, which shafts rotate within suitable journals on the table and .are rotated in spectively. The gear 139 is secured to. the

lower extremity of the shaft 135 and meshes with the gear 140 secured to the horizontal shaft 67 and by means of which intermesh ing gears, rotation is transmitted to the shaft 135, and from said shaft transmitted to the shaft 136 through the described meshing gears 137 and 138. The first set of forming rolls only partially form the seallng strip, and from said rolls said strip is delivered to the second set of forming rolls 141 and 142, which'are 'mounted respectively uponv the shafts 143and 144, Fig. 16 of the drawings, and which shafts are rotated in unison through the medium of the gears 145 and 146 mounted respectively on the said shafts.

To the lower extremity of the shaft 143 is secured the gear 147, which meshes with the gear 148 secured to the horizontal shaft 67. Interposed between the feed rolls 125 and 126 and the first operation forming rolls 133 and 134, is located a reciprocating knife 149, Figs. 2 and 14 of the drawings, which knife works within a guide block 150 secured to the u per surface of the table 20 and the said nife is adapted to cut the sealing strip at redetermined times, as hereinafter describe which knife is normally held outward by the tension of the spring 151 and by means of a bell crank lever 152 pivoted at 153 to the table 20, the said lever being connected at its outer end to a longitudinally movable bar 154, the opposite end of the said bar in turn being connected by a pivoted lever 155 to the table 20 at the point 156, the free end of the said lever 155 being extended inwardly to lie within the path of the arm 86', so that when the said arm is moved longitudinally inwardly with the travel of the operating slide plate 89, the same as it approaches the end of its stroke will engage with the inner end of the said lever 155 to throw the same so as to actuate the rod 154 to force inwardly the knife 149 for severing the web 122 intermediate the feed rolls and the first set of forming rolls.

At a short distance beyond the second set of forming rolls 141 and 142 is located the sealing roll 157 (Fig. 13) which is attached to a shaft 158 journaled in .suitable bearings formed on the under surface of the table 20, Fi 13 of the drawings. To the outer end of said shaft 158 is secured a gear 159 which meshes with a gear 160 on the upper end portion of a vertical shaft 161, journaled in bearing brackets 162, se cured to the frame of the machine and which at its lower end carries, a gear 163, and

which gear 163 is secured to the lower-extremity of the shaft 161 and meshes with a gear 164 mounted upon a shaft 165 jour naled inbrackets 166, secured to the base plate 2 of the machine.

On the shaft 165 is secured abeveled gear 167, which meshes with gear 168 car.- ried by the shaft 12, Fig. 1 of the drawings. Above the sealing roll 157 is located a companion vertically rotatable sealing roller 169 which cotiperates with the' roller 157 for compressing the sealing strip onto the flanges ofthe clamped can body and end, Fig. 13 of the drawings. The roller 169 is carried byv a shaft 170 which is journaled in a hinged bearing bracket 171, which end of the shaft 170 is attached a gear 174, which receives rotation from a gear 175 which is mounted on the shaft 158 and works throu h an opening in the table 20. The hinged racket 171 carrying the shaft 170 is connected with a cap 177 secured to the upper end of a vertical slidable shaft 178 by means of a link 176, the said cap 177 carrying a cam follower 179 operating upon a cam 180 secured to the drive shaft, and is normally held upward by means of a spring 177 secured onthe shaft 178 inter mediate the cap 177 and the u per end of the guide bearing for the sai shaft 178. The shaft 178, which is slidable within the table on a stud 182, which holds the said plunger'to the head of the shaft 178 and which plunger turns freely on the ball'bearings 182 in position between the same and the said head of the shaft 178. Within a seat 183 of the table 20 is'located or seated a circular disk 183, which disk is in axial alinement with the plunger 181 and is held in place relative to the table 20 by means of a supporting stud 184, the said disk turning freely on the anti-frictional balls 183 in position between a bearing plate 183" andthe underface of said disk. The cam 185 secured to the shaft 161 intermediate of its length and provided with a cam groove 186, operates upon a cam follower 187 carried by a yoke 188, which yoke is connected by a rod 189 to the crank lever 190 secured to the lower end of a vertical shaft 191, which shaft carries at its upper extremity a can of the machine and is normally held, out-' wardly pressed or in a backward position, by means of a spring 196 which is attached at one end to the said lever and at its opposite end to the frame of the machine. This lever is provided with an extension 197' which is adapted to press against the sliding clutch disk member 7 for controlling transmission of the rotation from shaft 13 to shaft 67. The upper end of the said lever 194 is in line with a lug 194 formed onthe lower end of the rack 89, Fig. 7 of the drawings, so that the lever 194 is actuated by the slide movement of the said rack 89 which is carried by the slide 86.

Should there come a time during the operation of the feeding of a can end 50 or of a can body 103 when there is no end in position for its associated can body, or when there is no body in position for its associated can end, it is necessary to hold the said end, or the said body, as the case may be, and prevent the same' from moving toward the sealing mechanism until there is an associated body for an end and vice versa. The following mechanism is for such a purpose and comprlses, broadly, a can body detecting apparatus, a can end detecting apparatus, and mechanism associated therewith whereby should either the can body or the can end detecting apparatus be operated by reason of there belng no body or end in position, the sliding feed parts of the machine will cease to o crate until the deficiency has been supp ied.

As seen in Figs. 1 and 11, a cam 198 provided with a cam groove 198 is secured to the upper shaft 4, and said groove 198 operates upon a cam follower 199 secured to a yoke 199. A sliding spindle 200 fastened to the yoke 199 slides within a bearing 200' formed in the frame 1 and is provided at its lower extremity with a collar 201, and provided intermediate its length with a collar 201, both-collars being rigidly fixed to said spindle. A spring 202 surrounds spindle 200 and is interposed between the upper surface of collar 201 and the lower surface of a forked portion 203" of a lever 203, which is pivoted at 204 to the frame 1. Pivotally connected at 204 to the opposite end of lever 203 is rod 205 which slides'vertically within a guideway 206' formed in the frame 1, and said rod carries at its lower extremity a can body detecting shoe 205'.

A spring 206 surrounds spindle 290 and is interposed between the upper surface of the collar 201 and the lower surface of a bushing 207 surrounding the Spindle 200' and sliding within a chamber 207' formed in the frame 1 below the bearing 200C vious that a lifting of the spindle 200 by the action of cam 198 as aforedescribed, tendsto lower the shoe 205 and also tends to raise the bushing 207. If, however, the shoe 205' is prevented from moving downward by reason of a can body 103 being below in its path of travel, the spring 202 is compressed during 208 formed in the frame 1.

It is obing the full upward movement of the spindle 200. In like manner, if the bushing 207 is prevented from moving upward, by a reason hereafter to be described, the spring 206 is compressed during the full upward stroke of the spindle 200.

Back teeth 205 formed on one side of the rod 205, as shown in Figs. 11 and 12, mesh Wlth teeth 208' out in one side of a horizontal shaft 208 which rocks within a bear- As seen in Figs. and 12, a cam 209 is secured to the opposite end of the shaft 208 and said cam lies directly beneath an extension 96 of the clutch member 97 If there is no can 103 in position beneath the shoe 205 (Fig. .11) to stop the downward travel of the rod 205, the shaft 208 is partially rotated through the toothed connections 205 and 208' and the cam 209 carried by said shaft lifts the clutch member 97,0ut of engagement with the mating clutch member 96 and no rotation is imparted to the shaft 95.

As seen in Figs. 11 and 12, rack teeth 210 formed on one side of the bushing 207 mesh with teeth'210' cut in one side of a horizontal shaft 211 which works within a hearing 211 formed in the frame 1. Said shaft 211 (see Figs. 9 and 12) -is provided at its opposite extremity with an eccentric portion 212, which is encircled by a crank arm 213 connected with one end of a bell crank 214 which is pivoted at 215 to the frame 1. Said bell crank 214 is provided with a tapered finger portion 216 which is adapted to enter a channel 217, formed within the turret 19 adjacent to each pocket 31, as seen in Fig. 9. A sliding pin 218 seated within the channel 217 is normally held outward by means of the spring 219, as seen in Figs. 2 and 9. Secured to the shaft 211 intermediate its length, as seen in Figs. 10 and 12, is a cam 220 and said cam lies directly beneath an extension 221 of the clutch member 97. If there is no end in the pocket 31, Fig. 9, to stop the inward travel of the pin 21 the shaft 211 is permitted to partially rotate and the cam 220 lifts the clutch member 97, Figs. .10 and 12, out of engagement with its mating clutch member 96 and the shaft 95 remains stationary.

It is necessary in case a gasket lined can end is contained within one of the seats of the rotatable turret and there is no can body in position to be fed to the initial assembling position or station of the apparatus,

that the said lined can end be prevented from being delivered to the said initial assembling station and for this purpose it is required that the same be held or maintained within its seat of the rotatable turret 19. This is accomplished through the medium of a yoked lever 223 which is pivoted at 224 to the table 20 and which is normally held in an upward position with its upper surface flush with the under face of the turret 19 by means of springs 225, Figs. 6, 7 and 9, of the drawings, the said spring held yoke lever 223 being interposed between the reciprocating feed slide 86 and the under surface of the rotatable turret 19.

It will be understood that the reciprocating feed slide 86 is held at rest at such time as rotation is not being imparted to the shaft 95, for controlling the actlon of the feed mechanism for the can bodies and the reciprocating movement of the slide 86, as set forth hereinbefore. Inasmuch as rotation is not imparted to the said shaft 96 when a can body is not in position for feeding to the initial assembling station, the said slide 86 will remain stationary or inactive at such times.

As the plunger operates to apply the gasket liner onto the flange of the can end and depress the lined can end from within its seat, the pressure thereof acting against the yoked lever 223 depresses the same to place the gasket lined can end within the sphere of the projection 88 of the feed slide 86, but as no movement at such time is imparted to the said slide the can end is not engaged by the projection thereof. As the plunger 80 moves upwardly to normal posi-- tion, the action of the spring pressed lever 223 raises or carries the gasket lined can end within the seatof the rotatable turret 19, from which it was removed by the downward action of the pluger 80. As the rotation of the turret 19 is an intermittent one, motion or rotation is imparted, thereto the moment the plunger 80 moves from within the seat thereof and the gasket lined end is moved therein, and the gasket lined end is moved with the rotatable turret and carried toward a discharge opening 227. The spring held yoked lever 223 thus acts as a resilient support for the can end during the time that the gasket liner is being applied onto the flanged portion of the said end and for the lined end as depressed from within its seat. To the table 20 below'the turret 19 is secured a circular guide bar 226, Fig. 6 of the drawings, and the said turret is cut away on its under surface as shown at 226' to clear the bar 226, Fig. 4 of the drawings, the purpose of which bar 226 is to hold the nondischarged can end within the pocket of the turret 19. The discharge opening 227 within the table 20 is located within the path of travel of a non-ejected gasket lined can end carried by the rotatable turret, so that when the seat or pocket of the turret containing said non-discharged gasket lined can end is brought into registry with the said pocket 22?, the said gasket lined can end will drop therethrough, Figs. 4 and 6 of the drawings.

As illustrated in Figs. 2, 6 and 17 of the drawings, there is rovided, adjacent the assembling station a downwardly extended inclined chute 228, into whichchute the sealed cans 103 are discharged by the ejector arm 193, and by means 'of which chute the sealed cans are conveyed to any suitable position or place of deposit.

From the foregoing, the operation of the machine will be readily understood, the same in brief consisting of the following steps, viz

A lined can end and a can body to which the end or bottom is to be applied are first brought, by means of the reciprocating feed slides, into axial alinement at the initial assembling station Gr, at such time the can body being held in superimposed relation to E the lined can end or bottom and held separated therefrom by means of the plate 113, Fig. 10 0f the drawings. WVhen the parts stand in this relation, the second inward stroke or movement of the feed slide 86 and 8 the actuating plate 89 carrying the bracket or arm 86 transfers the lined can end or, bottom and the lined can body from the station G to the assembling station H, during which movement or transfer of the parts the 9 can body is gradually placed onto the lined can end or bottom as the same is placed onto the rotatable support 183. With the parts thus positioned, the plunger 181 descends to clamp the can body and lined can 9 bottom to. the disk or plate 183, the. parts when thus clamped being held between the freely rotatable members 181 and 183. i It will be understood that as the can body 1s being brought into superimposed position 1 relative to the lined can end or bottom and the parts conveyed in axial alinem nt from the initial assembling station G to the assembling station H, that the sealing strip 102 is fed by the feed rolls and 126 1 and the forming rolls 134-435 and 141-14=2 to and between the sealing rolls 157 and 169, Fig. 13 of the drawings, so that by the time the can body and lined can end 'are clamped between the members 181 and 183, 1 the sealing rolls begin the compressing of the U-shaped sealing strip onto the flanges 1 of the held can body and lined end, and

that during the compressing operation the said sealing rolls serve to impart rotary l movement to the held can body and lined end, rotating. therewith the members 181 and 183, whlch rotary motion is continued until the cut length or section of thesealing strip has been completely compressed circumferentially relative to the flanged end of the. can body and the flange of the lined can end or bottom, when the upper sealing roll is raised or lifted, the action of the spring 177", the tension of which is released 11 at such time by reason of the cam 180, having moved from within the sphere of the roll 179. When the upper sealing roll 169 is thus raised out of contact withthe cornpressed sealing strip, rotation of the sealed 1i
