Application filed February 2, 1927. Serial No. mazes.

This-invention relates to compound apfplying or lining machines for can ends, and has more particular'reference to the promsion of a compound applying or lining ma-' 5 chine adapted interc angeably to successively and commercially apply llmng compound to'fianged'can ends of both circularv offset from the flange of the end by a' shoulder which fits within the tan body and the outer edge of the flange is curled; This construction of the end provides a channel at the flange, in'which a gasket, or lining materialis customarily provided. In the seaming operation, the flange of the body isinserted past the shoulder on the end and within the curl. The parts are then rolled together into tight relation. The lining material provided upon the flange of the end is thus rolled into the seam as it is tightly compressed to provide \a hermetic closure. The lining material is H frequently applied in liquid or semi-liquid form as a compound which not infrequently contains rubber. This compound is dried by air or in a suitable apparatus to solid form. The

double seaming operation isadelicate pne, and it is desirable that exactly the right amount of compound be ap lied evenly 5 throughout the entire can end ange length. My invention contemplates the provision of an apparatus for accurately applying lining compound to a can end flan'ge, whatever the contour or shape of the end may be,

ssm-aand this through the provision of simple in- ,strumentalities and devices adapted for certain accurate operation, and which are un likely to require constant attention and/or frequent repair, replacement or readjust-' ment of the parts.

Another lmportant' object of the invention isthe' provision of an apparatus of this character which may be'readily converted from an arrangement accurately lining a can end into an arran ement to line an end of .a

wholly different s ape.

Another important object of the invention is the provision of a can end compound liner which will be 'fully automatic in its action 5 and adapted with equal facility to be emtion of the no can no -structlon; and:j

ployed for the lining of circular, rectangular, and other non-circular ends through simple substitution of parts.

Another important object hi the invention is the-provision of a can end compound lining apparatus wherein no compound will be applied or will be. delivered from the linin nozzle unless a can end be present to recelve'the compound.

Another important object of the invention is the provision of an apparatus for applying compound lining material to can ends wherein the lining material may be maintained at even predetermined temperature until it is delivered from the nozzle, thus permitting the employment of compounds which will congeal or thicken in ordinary room temperatures.

Numerous other objects and advantages of the invention will be apparent as it is better understood from the following description, which, taken in connection with the accompanying drawings, discloses a preferred I embodiment thereof.

Referring to the drawings: Figure 1 is a top plan view of'an ,app'aratus embodying my present invention;

Fig. 2 is a partial enlarged plan detail thereof, the parts being shown in section;

Fig. 3 is an enlarged side elevation of the same showing an end feed;

Fig. 4 is a vertical section taken transversely of the apparatus atthe lining sta- C tion, and taken substantially on line 4-4; of Fig. 1; v

Fig.5 is a vertical section taken through the nozzle sup ort and showing the nozzle organization ta en substantially on the line. 5-5 of Fig. 1;

through a portion of the driving mecha- 7is a section taken substantially on the line 7-7 of- Fig. 4; V Fig. 8 is an enlarged detail showing a por- I compound feed con- Figs. 9 to 12 are details of the Geneva movement for controlling the rotation of the presented can end.

The embodiment of m invention shown on the drawings contemp ates thefeeding of can ends either automatically or by hand to: a lining station, where the end is lifted b a support to enter clamping engagement wit 1-10- a clamp arranged thereabove. After the end is lifted, it is rotated throughout more than a complete rotation, and preferably throughwhich is arranged above the flange of the out a rotation and a half, this being for the purpose. of giving time'to accurately start and stop the delivery of the compound.

The compound is delivered by a nozzle end, A' valve is opened after the end has started to rotate and is closed before it finishes. Preferably, this valve remains open merely long enough to give the smallest possible overlap to the applied compound on the flange. The nozzle is mounted 'uponan arm that swings about an axis remote from the nozzle, the nozzle being capable, therefore,

of moving froni and toward the axis of the rotation of the end. i

A cam is mounted in the present embodiment of the invention beneath the can end,

and this cam is provided with a groove of exactly the shape of the end. A cam roller engages in the groove and is arranged upon the end of anarm adapted to move with the nozzle; i. e. to cause the movement of the nozzle in accordance with theshape of the flange on the end.

A tank for the compound is provided, and

the delivery conduits between the tank andthe nozzle are all heat-jacketed; or at any rate, provided with jackets adapted to contain a heating medium, so that when desired the compound-ma be delivered to the flange at predetermine temperature. The construction and arrangementof the parts is such that merely by changing the construction and period of nozzle opening, the appa- ,ratusmay be arranged to accurately deliver compound lining material to the flanged can ends of different configuration.

Referring to the drawings: Reference character 21 indicates a suitable bed or table construction supported in any usual or preferred manner by a base framework 22; v 1

Reference character 23 indicates the can end support located at the lining station.

' Two can end guides 24 are arranged to lead connected by a connecting rod 32 with a crank pin 33 on a crank disc 34 fixed upon a shaft 35 mounted in bearings 36 (Fig. 6)

in the base frame of the apparatus and con-- tinuously rotating, as will hereinafter be 'described.

Each feed slide 26 is provided with a feed shoulder 37 adapted to engage behind a prefarm 53 beneath the table.

sented can end 38 to advance it on to the support 23.= The can end support 23 .is

mounted upon the upper end' of an axially j movable and rotatable shaft 39, which is-po- I sitioned through asleeve'4l having bearing.

in'a bushing42 extending throughthemain frame at 43;

- Preparatory. to each ,lining operation, the

can end support is adapted to be lifted by mechanism to be presently described into engagement with an upper clamping mem;

ber 44 idly and freely rotatable about a shaft or sleeve45 threadedly engaged at 46 in an arbor 47 extending up from the table 21 to which it is secured by a bolt'48,ba ll bearings 49 being provided if desired.

pivoted at 52 in a downwardly extending One arm of this The upward movement of the can sup- I .port withthe can end carried by it is accomplished by. a bellcrank lever 51 (Fig. 3).

bellcrank is bifurcated at 54 and is provided I with pins 55 engaging ina slot 56 formed in a collar 57 secured on .the lower end of 'the shaft '39. The other arm of this bell-' crank extends up into engagement with a I end of the'slide and an adju'stablebolt 63 arranged through an upright 64 from the guideway 61. The purpose of the slide bar 59 is to lock certain parts against move 'ment, except when suchflmovement 1s de sired. The bellcrank 51 is provided with'a roller-65 which engages a cam 66 having a lifting dwell 67 for maintaining the can end support in lifting and clampin tion throughout the predetermined desired period. A desired and predetermined rota tion is imparted to the supported can end and clamp after the parts are in clamping relation, and this is accomplished by a Geneva movement to be now described, reference being had to Figs. 3, 6, and'9 to 12.

A shaft 71 is mounted in bearing 7 2 alongside shaft 35, and this shaft is provided with posi-.

' pin 58 fast in a slide. bar 59 mounted'upon a slideway 61 beneath the bed. The bar 59' and the bellcrank 51 are pushed to lowered position by a spring 62 hearing against an a beveled gear 73. which meshes with a beveled gear 74 on a shaft 75 arranged vertically in bearings 7 6 beneath the bed. The shaft 75 carries a gear 77 which meshes with a gear 7 8 keyed to shaft 39. The shaft 71 also is provided with a Geneva pinion 79 adapted for engagement with a Geneva seg;' ;ment 81 on shaft 35, or rather upon a sleeve 82 fixed on said shaft. This sleeve also has fast to it the Geneva disc 83, circular in form except that it is cut away throughout the are of the segment 81. .A rider 84 is mounted upon the hub 85 of-the Geneva gear 79, and is adapted to ride upon the outer face of the Geneva disc to prevent rota tion of the shaft 71, except when the Geneva segment is'rotating the Geneya gear.

At each end of the arcuate-portion of the disc 83, the corners 86 are cut away to facilitate the engagement of the grooved face 87,

to permit the arcuate face of the rider 84 to readily engage and disengage the circumferential face of the Geneva disc.

- In order to insure positive engagement pf the tooth of the gear segment in accurate meshed relation, and also to insure accurate engagement of the gear of the Geneva rider, with the Geneva disc, I fix a member 88 on the shaft 79, this member having arms 89 and 91. A companion member 92 is fixed i an upon the shaft and atappropriate points two rollers 93 and'94 are arranged 1n the path of travel of the arms 89 and 91.

Fig. 11 shows the varrangement of the parts of the Geneva movement during. the feeding of a can end on the can end support, and continued rotation of the shaft 35 causes the roller 93 to engage the arm 91 as the segment approaches the gear. The

circumferential face of the Geneva 'disc is v cut away slightly at 95 to permit this.

Fig. 9. shows'the-segment and gear in engagement, during which time a revolution and a halfis imparted to the can end sup port.

Fig. parts. at

12 shows the arrangement of the the end of the Geneva action, the

' roller 94 engagingrback of the arm 89 and swinging the r1der 84positively into engageflange of -the can end throughout a full complete revolution of the end. Construction of this nozzle and attendantsparts is perhaps best shown in Figs. 1, 4, and 5.

A tank 101is'mounted on the bed 21, and is provided with an outwardly extended hollow deliver arm 102 formed at its end remote from t e tank into a bearing sleeve 103. A shaft 104 extends through this bearing and upon it is fixed a sleeve 105 of a nozzle support and conduit 106. The nozzle proper 107 is mounted 'in the outer end of the support 106. All of the parts are preferably arranged so that heat may be continuously applied to the compound material, and to this end the compound is contained within an inner chamber 108 in the tank and the passageway 109 through the arm 102 is jacketed at 111. A steam jacket 112 is or may be provided through the nozzle support 106 and about the passage 113. Communication between the passages 109 and 113 is formed by a simple bore 114 extending vertically through the shaft 104, en

larged openings 115 and 116 being provided in which it also has bearing.

end, this rod is provided wlth a can end de to establish communications with the passageways 109 and 113.

The nozzle is adapted to be swung about the center of the shaft 104 to follow the. contour of the flange ofcan end. It is fast on the ing 103. The movement of the nozzle with the flange of the can end is accomplished by a cam 11'? mounted beneath'the can support and fixed to the sleeve 41 at 118 thereof. The sleeve 41 turnswith shaft 39 and the cam with it. This cam is provided with a groove 119 within which is engaged a cam roller 120 upon the end of an arm-121. The arm 121 is fast upon the lower end of the shaft 104, so that the shaft isi.rocked-'by the cam in accordance with the departures of the flange contour from a true circle. The open shaft 104, which is free to turn in the bearing 115 is s'uflicient to permit freecommunication between thepassage 109 and the passage 114 throughout the range of rocking movement.

,A manually operable alve 122 is provided in the bracket 102 and an automatic valve 123 is provided to open and close the nozzle 107 at the desired instants in the cycle of operation. Thevalve 123 consists of a valve rod adapted to open and close the passage 113, this passage when open communicating with the vertical delivery passage. 124 to the nozzle. The valve rod 123 extends out through a sleeve housing 125 having bearing in a cap 126 at the top thereof, and is provided at its upper end with a head weight 130, which engages upon the top of an arm 127, the rod passing through an opening 128 therein. This weight and the weight of the rod normally hold the valve 123 in closed position, and this arrangement maintains until the can end support has received a can end and has started its rotation.- If no can and ispresent upon the-lifting of the can end support, the valve remains closed.

"The mechanism for thus controlling the nozzle 123 will now be described: A vertically'reciprocating rod 131 is mounted in a bearing 132 and passes through a sleeve 45, At the lower tector head 133 located just above the can end support when in lower position. A re cess 134 is provided in the top of the can end support and if no can end be present When the support is raised, the head 123 engages the bottom of the recess and is lifted with the support. If, however, acan end bepresent, the presented face of the can end engages with the rod. 131 at 140. I

- A bracket 135 is fixed to the rod'by pins 136 and carriesa lifter ledge 137 adapted to engage under a roll 138 provided on the end The ledge 137 (Fig. 8) is fast upon the upper end of a Vertical slide rod 141 mounted'in bearings 142 and 143 in the bracket 135, the ledge member normally resting against thefllower bearing 143. ,The slide rod is looselypivoted at 144 to a lever 145 pivoted in turn at 146, to the bracket.

shaft 35.-

The lever 145 is in turn engaged at 147 with a link 148 to a bellcrank 149 pivoted at 151 adjacent the The bellcrank 149(Fig. 7) is provided with a roller 152 adapted to engage a continuously rotating cam 153' on sh ft' 35, which cam has a nozzle opening dwel 154 adapted to engage the roller 152 and swing the bellcrank in a clockwise'direction (view ing Figr7 This pulls downwardly on the link 148, swinging the lever 145 to further raise the lifter ledge 137 and open the valve throughout the time that the dwell 154 is engaging the roller 152.

In order that the can support, and more particularly the cam 117 shall be in accurate position to starta can lining operation, means are provided for locking the gear7 8 against movement while the can end support is lowered. A collar 161is fixed on the shaft 39 and this collar' is provided with a recess gFig. 3) into-which the slide bar 59,

alrea cribed,-engages atthe end of each rotation of the can end support, and from which it is onlywithdrawn wheh'the dwell 67 of cam 66 positively withdraws it pre-f .paratory tothe startin of the next rotation. Power is introduced into themachine from a power pulley 171 "mounted upon a shaft 172 having bearingfias at 17 3 inv the frame. This power shaft-172 is provided with a pinion 174 engaging a gear 175:on shaft 35. Shaft 172 also carries a beveled pinion 176 which meshes with a companion-pinion 177 on a cross-shaft extending, through bearing 17 8 in the frame and carrying at its opposite end a sprocket wheel 179, which sprocket Wheel is employed to drivean agitatorof any suitable type of construction in tank.101.-

The gear 175 is yieldingly secured on shaft 35 (.Fig. 6) in orderihat should the appw ratus become jammed from any cause,"the power maybe disconnected fromthe operating andmovingparts. A clutch collar 181 is slidable longitudinally of the shaft35 and ispressed toward the gear by a spring 182w.

bearing against a spring holding collar 183 fast onone end of the shaft. The hub 184 of the gear 175' is provided with a clutch tooth 185 which normally engages in a com.-

panion recess 186 in the sliding collar 181. After the can end has been lined and're-- turned to lower position, it is removed by the same feed bars 26 that positioned it upon the support. Tothis end forward lugs 191 are arranged .on the feed bars and'in position' to engage behind the end and advance it in the direction of feed after a lining op, eration. The timing of the apparatus is While the can end previously fedis'lifted out-of its r eturnpath oftravel.

In delivering the can end from'the can end support, it is carried by the feed bars on to a belt 192 which is trained over a drum 193 fixed on a shaft- 194 having bearings'at 195 in the frame" The shaft 194 is provided with a sprocket 196 connected by a sprocket chain 197 with thesprocket wheel 198. on
