f The present invention relates too. can andcover assembling machine and has particular reference to associated devices insuch a machine forapplying an adhesive to a fibre can'a'nd thenmoving it past a positioned. fibre cover withwhichit is then assembled and, attached in a glued joint.

,The principal object of the present invention is theprovision of a machine for automatically rolling or conveying a can body alongside of, adhesive applying devices which 1 apply and evenly; 'distribute; a liquid, adhesive material on an edge andon a small section of itsadjacentbody wall,

provisionof a control device for a can'and cover assembling machine which isoperated by the ,presence of a can body to insurethe properpositiming of a can cover tor an assemblingoperation. An important object of the invention is thepro vision oi a cover feeding device for carrying covers in an arcuate pathof travel and a can bodyfeeding device which presents parts of the to, adhesive applying rollers and then" carriesthe can bodiestangentto the positioned can covers. thus effecting assembly of the two.

A still furtherand important object of the invention isthe provision of an apparatus of the character described whichis adapted to position fibrerflanged covers having pouring spouts onto fibre .bodies by providing an adhesive union bewith the accompanying drawings, discloses a pre? ferred embodiment thereof.

. The apparatus disclosed in the drawings for the purpose of exemplifying the invention, comprises a series of interconnected devices for feeding fibre can bodies in a continuous, 'trave1,.first,separating and ,spacing, the vindividual? bodies as they come from a supply chute and then rolling them along adhesive applying rollers so that one edge and the outside wall part adjacent is supplied with anadhesive material, the rolling can'body being yieldingly held downwardly and i endwise s h mllers-wl Further travel-pf the can body is effected by a rotating feedturret which receives' it in a pocket of the turret and moves it through an assemblin station where itreceivesa. "cover. l At the same time .fibre covers areffed into the machine in processional order and-are placed sojthat one of the covers may be positively positioned for engagement with one end of the can body while still l-within the turret pocket, A cover is not so positioneduntil a tripdevice has been actuated by a preceding can that has already received its cover. This will bemore fully explained.

As the canbody in the turret is about to engage the positioned coverit is sprung out of, its cylindrical shapeinto an oval shape, so that its ,forward edge will be sure to pass to the inside wallloffthe cover cane When engaged the movingcan forces thecover outof its seat. The canfwith its engaged, cover then. passes between closing plates at" the assembling station which force thecover hornenpon the openend of the Y rounded up and brought to true form by a mating turret cooperating with the feed turret, this being attheassembling stat ion. .j

The can with its glued cover is thenirelease'd,

from the turrets v and is dropped into a discharge runway mange-which itrolls' out of the machine. The trip device previously referred to i's-a' no-canjbody no-cover njiechanisrn and a part of this mechanism is arrangedinthe discharge runway and is actuated by the can as it is being carried into the runway by 'the two mating turf This trip-device actuates th"e"cover feeding mechanism which places another coverinto posi tion for engagement by the next succeeding-can body.

As can and cover approach the assembling sta-- tion, the'cover spout 233 moves into engagement With-a curved plate 296 which'is secured'tothe block'292 with'its upper end extending into the slot 293 of the block. This curved plate hinges the-spout'into closed position on its cover so that Whenthe cover is fully assembled with the can body the cover end is fully closed.

A roundingup turret 297 (Figs. 2 and co operates with-'and'islocated adjacent to the turret--178,' being keyed to a horiz'ontal shaft 298 journaled in'bearings' 299formed'in the frame 22. This shaft 298- is parallel to-the other turret shaft 52 and rotates atjthe same 'speed but ina reverseddirection of travel: A gear300 is keyed to the shaft 298 intermediate its bearings and meshes with and receives rotation from the gear'f 51 (Fig. 1)'. In this way the turret 297 =is retate'd in a counter clockwise direction, asviewed in I The turret 297 is provided with pockets-"301 and one of these pockets cooperates with the-pocket- 177 containing the newly engagedcan and cover." The cooperatingturret pockets form half-molds forthe can body and round-it up and hold itto itscyli'ndrical shape, this being immediately after the can-body has passed by the blocks 291, the complete rounding up taking place at the assem-- bling station.

-*From'rthe assembling station the can body with itsfullyaLpplied c'over passesinto a runway where it operates a trip lever connected with thecan cover feed andthenrolls out of the machine. This runway is formed by a'-'single right angle side and top railand by three right angled-side and bottom rails The legs of thesefirails" are joined by curved sections as illustrated-in the drawings. The former, a guide rail 305 (Figs. 1 and 2), is located in a vertical plane passing centrallyof the can bodies in the'turrets 178, 297.

' This rail is supported upon'horizontal stationary posts 307 which project from-bosses 308 formed in thefront'wall of the housing 22. The vertical legof the rail 305 'form s'an outer side guide for thecans and its horizontal leg provides the top guide.

The {opposite side of the runway formed by an inner short rail 309, an outside rail 310 and a central rail 311. The vertical legsjof'these three rails provide the inner part of the runway while their horizontal leg sections form the bottom or supporting part. Rails'309 and 310 are also formed with vertical side flanges312, 313 between which the can bodies are retained laterally during their passage along the runway. The rails 309,310, 311 are carried on posts-314, 315 which project forward from bosses 316formed in the housing 22. f The continued rotation of the turrets 178, 297 forces thecan and cover downwardly into the upper part of the runway andas the pockets 177, 301 of the respective'turrets separate, the can is freed and falls by. gravity,",passing'first through thevertical section of the runway, thence'around the curved partand finally along the horizontal section-and out of themachine. v

It is while the can body is being'positivelyloW- mea re and will 'now be described.

This trip device comprises a rocking lever arm 317 (Figs. 2,10 and 13) having a contact head 318 which projects into the upper end of the run-f Way and into the path of travel of the can body. As the'can body passes between the vertical legs":

of therunway the lever arm is actuated.

The lever arm 317 is secured to one end of -a horizontal rock shaft 321 which is'mounted ina' bearing 322 formed in the bracket 222'and in'a: bearing 323 formed in a bracket 324 mounted upon and bolted to the housing 23.

The opposite end of the rock shaft 321 carriesan arm 327 (Figs. 4, 9 and 10), the upper end of which is pivotally connected at 328 to a 1ink'329 pivoted at 331 to the rear;endof the rod'286.

The arm 327-is formed with an extension 335 which projects downwardly' below the shaft 321" and engages a spring pin 336 which is slidingly mounted in a tubular boss 337 formed in the bracket 324. This spring pin 336 is backed up by a spring 338 which urgesthe pin 336 toward the i right, as viewed in Fig. 4;- and this normally" causes the arm 327 to move the pin 286into its lever locking position. "The 'shaft"-321' is alsomoved by the spring-338-and this normally'holdsf the trip lever 317 into thepath of travel of'the capped can bodies.

The engagement of the upper end or head 318 of the trip lever 317 by a can body andgthe resulting oscillation of the shaft 321 effects the a movement of the arm 327 against the action of the spring 338 and this withdraws the pin2 86 from locking-position and allows the cooperation of am roller 271 and cam 274 to project the'pins 282' i'nto'cover feeding position as scribed.
