METHOD oF AND APPARATUS FOR LINING CLOSURE ELEMENTS.

' Application filed November 28, 1924. Serial No. 752,728

The present invention relates to a method of and apparatus for lining closure elements for containers.

One object of the invention is to provide an improved method, by which the production of large numbers of insulated closures for containers and the like may be rapidly efiected in an economical and eflicientmanner. More particularly, the present method embodies the intermittent feeding of a series of closure elements to a predetermined point of operation, the feeding of suitable lining material in proximity to sa-idpoint, the severing of blanks of the proper size from said material, and the application of the blanks to the. closure elements. 7

Another object of the invention is to provide an improved machine in which the coordination of the operations necessary to assemble the closure elements and to form and apply the insulating blanks thereto is carried out in an efiicient and economical manner. I

Still another object of the invention is to provide a simple, efiicient and dependable machine which will intermittently feed a series of closure elements toa predetermined point upon a support and which will automatically and intermittently feed a strip of sheet material into registry with the closure elements at said point and sever blanks from the strip and apply the same to the closure elements the several operatingmechanisms being coordinated to perform the different operations in proper timed relation.

To these and other ends the invention resides in certain improvements and combinations of parts, all as will be hereinafter nore fully described, the novel features being pointed out in the claims at the end of the specification. v

In the drawings:

Figure 1 is a side elevation of a machine illustrating one embodiment of the invention; v

Figure 2 is a transverse sectional eleva tion taken on the line 2' a of Figurel;

Figure 3 is an enlarged sectional elevation taken on line 3 3- of Figure 1, and illustrating the means for severing and applying the blanks of insulating material to the closures; I

Figure 4 1s an enlarged-fragmentary. sectional elevation through the closure and the crimping die with the latter shown in its lowermost position upon the former;

a Figure 5 is a top plan of a portion of the Figure 7 is a diagrammatic View in ele-- vation showing one of the closures upon the feed bar with the blank in position to be applied to the closure by the crimping die.

Similar reference numerals throughout the several views indicate the same parts.

i The present invention embodies an improved machine for effecting automatic advancement of a series of closure elements preferably of the flanged or curled edge type to a predetermined blank applying position and includes means for intermittently feeding lining material to a point in proximity to the blank applying position, together with automatic means for successively severing blanks from said material and means operated in timed relation thereto for applying the severed blanks to the closure elements, either by crimping the blank upon the 010- sure element or by forcing its peripheral edge'portion behind or under an inwardly inclined or curled flange thereof, or' both as may be desired.

The closures or covers thus produced are adapted preferably to constitute the end walls of a well known type of paper container now in use, but may be employed in connection with any type of container requiring a lined or insulated cover or wall, said closures being suitably applied to the body of the container, as by crimping, or in any manner desired. The containers are preferably both air and liquid tight and are sanitary and extremely light in construction and of a durable nature.

In the drawings I have shown a frame 1 having a table 2 thereon and upright extensions3 at one side thereof. An anvil or bed plate is superimposed upon the table and preferably comprises the spaced plate members 4 and 5, shownin Figures 2 and 3, and are adapted to support the closures 6 while the blanks of insulating material 7 are being applied thereto by the inserting and crimpcomprises a reciprocably mounted head 11 I manner shown in Figure l,

blanks are cut from a sheet or stripof paper 9, or any otherlmaterial suitable for insulat ing the contents of the containers from the metal end closures thereof. The paper strip, which is of a width sligh lygreater than the diameter of the blank ,7, is intermittentlyj i fed from a roll 10 into registry with the inserting or crimpingdie a nd the closure thereunder by a suitable feed mechanism Which Will be hereinafter ClGSGllbQd.

The blank severing means preferably having a ri ng shaped cutter 12 adapted to cooperate with the annular cutting edge 13 of a die 14 having an opening 15 in registry .with the anvil, the latter being adapted to support the closure centrally beneath the plunger 8 during the crimping or blank applying operation. The. paper is fed across the upper face of the cutting die 1% beneath a cover 16] supported by strips 1'? which form guides for the paper and which are suitably connected with the die 14%, the cover l6'hav1ng an opening 18 large enough to accommodate the cutting ring '12 or'mov-v able partiof the severing die. The cutting ring 12 is shown in its lowermost position in Figure 3, with the severed blanks if in position to be moved down and applied to the closures by the blank applying die 8, in the The head 11 whichcarries the cutting ring 12is suitably ings carried by 'the forwarr connected with the depending portions 19 of across head 20 by means of the upper and lower rings 21 and 22 and the screws 23 and 24 as shown in Figure 3. The cross head 20 is guided in ways 25 on the arms 26 pro jecting fronithe upright frame members 3, and 1s provided with extenslons 27 carrying rollers28 which engage cams 29 'upon a crank shaft 30, Journaled in suitable'b a w r arms 31 at the top ofthe frame nie nbers The crank shaft is provided with a flywheel 32 which may be driven by'a belt not shown, or by any meanssuitable for operating the Shaftl 'Thecr ank shaft is provided with a 39 which is centrally" disposer upon the crimping die 8 asshownflin Figure 3. A springi-ZS, is interposed between the connec tion 37 and the bottom wall- 39 of the die, whereby to form a yieldable connection between the crank shaft and the die, to avoid rupturing of any part of the mechanism.

The crimping or blank applying die is mounted to slide within the head 11 carrying the cutting ring 12 and is reciprocated thei eby the crank shaft, while the cu'ttingring is reciprocated by the action of the cams 29 and the springs 40 which constantly exert an upward pull onthe rods 4-1, the'latter being connected with the rearwardly' projecting arms 42 of the crosshead. The springs therefore serve to lift the cross head and the cutter ring to theiri-highest position when the cams are in the position shown in Figure 1'. 111 this position of thecams the offset portion of the crank shaft is at itshighest point "and consequently the crimping or blank inserting die is elevated the maximum amount," to the position'indicated by the dotted lines in Figure 2', Rotationof the crankshaft from the position indicated in Figure 2 in the direction indicated by the arrow will result in a downward movement of the cross head which will carry the cutting ring through the paper to sever'the blanks as shown in igure 3. Following closely after the blanksevering operationthe 'crank' shaft will "move the die 8 downw'ardly to carry the blank into engagement" with the closure and will both crimp it thereon and force its peripheral edge portion behind the inclined flange 43 of the closure, it being understood that the blank is out large enough to allow for the amount of material required to cover the beveled portionst i and 45 of the closure, as indicated in Figure 6.. The blank applying portion 'of' the die is so shaped as to'e'ffectively draw the paper downwardly upon the inclined portions 44 and l5 to crimp it thereon and at the same time is adapted to force the peripheral edge portionf lfi of the blank "be-- hind the inturned flange '43 and-into engagement with an'a-nnu'lar portion 47 of the closure, .as shownon an enlarged'scale in Figure 6. The crimping action gives a permanent set to the blank, corresponding to the shape of the closure so that the blank will remain in proper position upon the latter after it has been secured to the'botton'r of thecontaineror to the "movable end cap therefor, as theca'se. may her The exter nal appearance ofth'eblank when-crimped upon'the closure is substantially as indicated by the finished closure shown at the right of Figure 5,'which is at a point upon the anvil corresponding to'th'at shown in Figure 3, or in other words, in position to register. with the crimping die. V I

Although I have shown a dished form of closurc,it will be understood that my improved methodcontemplates the application of the lining blanks to closures, either of the dished or substantially flat type or of the flanged or nonflanged type, and. embodies the forcing'of the peripheral edges of theblanks behind the flanges of the closures, re

gardless of whether or not the shape of the.

closure is such I as to require a crimping action of the blank in applying it' to the closure. The J closure when completed, shown in Figure 6,are applied to the con thereon by a crnnping or seaming operation or in any well known manner.

The closures are advanced upon the bed plates or anvil bars 4 and 5 between suitable guide bars 48 and 49, the former being fixed upon the bed plate 4 and the latter yieldably mounted upon the bed plate 5, by means of springs 50, havingtheir inner ends seated upon the guide bars 49 and their outer ends upon a plate 51, the springs being carried by the stems 52 guided by the plate 51. Studs 53 project into slots 54 of the bars 49 and limit the movement of the." latter with respect to the closures. Both guide bars 48 and 49 are beveled as indicated at 55 to receive the inturned flanges 43 of the closures, whereby to hold the closures properly seated upon theanvil bars during their advancement to blank applying position. i v

The feeding mechanismfor the covers or closure elements 6 preferably comprises a 'reciprocably mounted bar 56 movable between the bed plates oranvil bars 4 and 5. The feed bar is provided with a series o-f fingers or projections 57 adapted to engage the closures as shown in Figure 5 to advance them step by step int-o registry with the crimping die where they remain long enough to have the lining applied thereto, the fingers being disposed in recesses formed in the bar and yieldably pressed upwardly by springs, not shown.

-An extension frame 58 is carried by the main frame 1 to support a holder for a series of flanged or curled closure elements as shown in Figure 1. The holder may be constructed in any desired manner, but preferably comprises a plate 59 having upstanding guides 60 for the closures and is provided'with an opening 61 slida-bly larger than the diameter of the closure elements to permit them to descend by gravity upon a pair of spaced plates 62, only one of which is shown, and between which the feed bar operates to successively engage and advance the lowermost closure of the stack through engagement of the outermost finger 57 of the bar with said closure when the bar begins to advance toward the crimping die from its extreme outer position, as shown in Figure 1. The feed bar may be provided with any desired number of the fingers 57 preferably 5, each of which advances a closure one step for every forward stroke of the bar. On the return stroke of the bar the'yieldably mounted fingers ride under the closures and thenmove back to normal position ready to advance the closure elements when the bar is again moved forwardlv. Upon advancement of the bar from the position shown in Figure 1, the front closure, upon which a blank has been applied, will be pushed forward and the second closure brought into ting rin and the die for applying the bla registry with the crimping die, while at'the same time each succeeding closure overlying the bar will be advanced one step. The

closures to which the blanks have been applied will be pushed forward by the advancement of the succeeding closures and carried to the desired point of discharge, preferably to a chute, not shown. However, if desired, additional fingers may be disposed upon the front end of the feed bar to successively engage and advance the completed closures to the desired point of discharge from the machine. I

In order to insure the proper feeding of the closures between the'rear ends of the guides 48 and 49 when the closures are passing thereto from the guide plates 62, I have pro vided between the guide bars a pair of shoes 63 connected with upwardly extending rods (54 and 65 which project through and are guided by a plate 66 supported by posts 67 on the frame 58, the receiving ends of the shoes being inclined upwardly so that the closures will more readily pass beneath the shoes, which are yieldably held in engagement with the closures by suitable springs 68 as shown in Figure 1.

Reciprocation of the feed bar in proper timed relation to the movements of the out to the closures may be effected by any suitable means, but preferably by means actuated by the crank shaft. This is done in the present instance by a pitman 69 having its upper end connected with a crank disk 70 on the fly wheel end of the crank shaft and its lower end connected with an arm 71 on a rock shaft 72 journaled in the side members 73 of the frame 1. The rock shaft carries an upstanding arm or lever 74 which is pivotally connected with the front end of a link 75, therear end of which is connected with an arm 76 depending from the feed bar as indicated in Figure 1. It will be readily seen that'upon each revolution of the crank shaft the feed bar will be advanced from and returned to the position shown in Figure 1, or in other words, a complete operation of the same will be effected,

The paper feed mechanism, as before stated, may be of any well known type, but preferably comprises a pair of feed rolls 77 and 78 mounted one above the other upon suitable brackets 79 as shown in Figure 2.

The upper roll is yieldably held in engage-.

ment with the paper by springsSO and is provided at one end with a driving gear 81 having an overrunning clutch, not shown, the gear being preferably operated by a rack 82 actuated by a pitman 83 driven by a crank disc 84 on the crank shaft 30 as shown in Figure 2. By this mechanism the paper riod of Withdrawal of the crimping die from blank applying position. 7

It will be understood that the present drawing are of a more or less conventional nature, but are sufiicient to clearly illustrate the principles of the invention and the method employed in the practice of the same, as well as to illustrate one type of machine suitable for a rapid production of the closure elements.
