UNITED STATES ARTHUR C. IMAYER, F INDIANAPOLIS, INDIANA, ASSIGNOR TO AMERICA N CAN COM- PANY, OF NEW YORK, N. Y., A CORPORATION OF NEW JERSEY.

GASKET-LINING APPARATUS.

Application filed November To all whom it may concern:

Be it known that I, ARTHUR C. MAYER, a citizen of the United States, residing in Indianapolis, in the county of Marion and State of Indiana, have invented a new and useful Improvement in Gasket-Lining Apparatus, of which the following is a specification.

This invention relates in general to apparatus for forming and-applying gaskets to the flanges of can ends, and has more specilic reference to means for preventing the feeding of can ends to be lined into the apparatus in the absence of a gasket in posi- ,tion to be applied.

In the operation of machines of this charf acter it sometimes happens, either because of imperfect operation of the feeding mechat nism or imperfect functioning of the cutting i devices, that a gasket is notpp g nt in the {turret at the point from which it should be applied to a can end, and in this event it is desirable to prevent the feeding of an end, since it must necessarily pass out of the ma- Fliiiibuiiliiet i it is a principal object of the present ini vent-ion to provide means controlled by the 5 presence or absence of a gasket at a certain 5' station in the apparatus for rendering ineffective the operation of the can end feeding mechanism unless am is ready to be 1 applied to an end, the mechanism which I have provided being descriptively termed a no gasket, no end device.

A. further object of the invention is the provision of mechanism for accomplishing the foregoing object which in no way interferes with the normal operation of the machine, and which is entirelynutomat ic in action.

Another object of the invention is the provision in apparatus of this character of means for restoring the operative condition of the feeding mechanism simply by the nornial operation thereof after correction of the condition which caused the stoppage.

Still another object of the invention is the provision of a relatively simple mechanical structure adapted to obstruct the operation of the feeding mechanism in the event mentioned, "-d a sensitive electrical control for said structure with precision and certainty in every instance of failure to provide a gasket at a predetermined point.

Numerous other objects and advantages of the invention will be apparent as it is 13Gb. ter understood from the following description, which, taken in connection with the accompanying drawings, discloses a preferred embodiment thereof.

Referring to the drawings,

Figure 1 is a front elevation of a machine embodying the principles of my invention;

Fig. 2 is a greatly enlarged plan view of a portion of the apparatus, taken substantially on the line 22 of Fig. 1;

Fig. 3 is a vertical section taken substantially on the line 33 in Fig. 2, certain of the parts being broken away for convenience of illustration;

Fig. 4 is an enlarged fragmentary view of a portion of the rear end of the machine, certain parts being shown in section; and

Fig. 5 is a horizontal section taken substantially on the line 55 of Fig. l.

The general organization of the apparatus in which my invention is embodied, in the present instance, may be observed by reference to Fig. 1, which requires only a general description since the greater part of the mechanism there shown is not concerned with this invention and is fully shown and described in an application heretofore filed by Magnus E. lVidell and lVarren A. Smith, bearing Serial No. 448,625.

The function of the structure of this machine is to form gaskets from blanks fed thereto and to apply the same to the flanges of can ends fed into the machine at a station beyond that at which the formative operation upon the gasket blanks takes place. To this end a turret 11 is provided in a frame 12 supported upon a base 13, and extending outwardly from the frame on the plane of the turret are supports 14: and 15) for the gasket blank and can end feeding mechanisms respectively. Stackholders 16 for the gasket blanks are provided above the support M, and feeding mechanism, not shown in detail, is employed to individually feed the blanks into ports 17 spaced about the periphery of the turret. The feeding of these blanks, as well as that of the can ends, which is done by means to be loo hereinafter described, and the various operations of forming and applying the gasket liners are accomplished by power introduced into the apparatus through a pulley 18 which is carried on a drive shaft 19 journaled in upper projections 21 and 22 of the frame 12. The pulley 18 is loose upon the shaft 19 and adapted to be operatively connected therewith by a clutch 23 operable by a hand lever 24E through a connecting rod 25 rotatably secured in the upper projection 22, and ca 'rying a depending fork 26 having connection with said clutch. A hand wheel 27 is provided for manual operation, and the parts just described are assembled nnder the pressure of a coil spring 28 on the end of the shaft 19. Said shaft carries a bevel gear 29 meshing with a bevel gear 81 secured on a vertical shaft 32, which at its lower end is provided with a pinion meshing with a gear 31 secured on a shaft 35 which has also secured thereto an arm 36 carrying a roll 37 adapted to drive the slotted wheel 38 with a Geneva stop movement. The wheel 38 is fixedly secured to a shaft 39 having bearings at 11 in the frame 12 and being operatively connected at its upper end with the turret 11. Through this mechanism an intermittent motion is imparted to said turret to permit performance of the various operations of the machine at predetermined stations. The shaft 32 has secured thereto just above its bearing -12 abevel gear 43 adapted to drive a combined bevel and spur gear 44 secured upon a transverse shaft having bearings in the main frame and having at its opposite end a crank disk &5, having secured thereto a crank pin 46 held in a wrist 17 and connected by a link 18 and a universal oint 19 with an arm 51 rigidly secured at one end to a shaft which is rigid with an arm 52 adjustably secured at 53 with the blank feeding mechanism heretofore referred to.

The blanks which are fed by the mechanism just described into the ports of the turret 11 are seated by a seating die 54ccarried by a rod 55 periodically recharocated by means of a bell crank lever 56 pivoted at 56 and carrying on its upper arm a roll 57 following the groove 58 of an offset cam member 59.

Subsequent rotation of the turret brings the blank to a station where it has the core removed therefrom by die members operated through the instrumentality of crosshea-ds 01 and 62 carried respectively on the lower and upper transverse shafts. The next step in the rotation of the turret brings the gasket, indicated in Figs. 2 and a by the reference numeral 03, to an idle station. which is the one immediately preceding the lining station at which a can end is fed into the machine by mechanism to be now described.

Stackholders 612 are provided above the support 15 for holding a supply of can ends which are individually separated and fed into the turret by a feeding slide 65. The stack extends through a guide 66 connected by pivots 67 and ($8 with toggle arms 69 and 71 and beveled stack lifters 70 and 70 respectively. The arms 69 and 71 are joint ed and carry rollers 72 and 73, their rear extensions being secured together by a spring 7 1 secured in notches 7 5 and 7 G. The slide (35 is beveled at 7'7 and is reciprocated by means of an arm 78 connected by a connecting rod 79 with a lower extension 81 of the arm 52. hen this slide is moved out wardly, permitting the rollers 72 and 73 to ride down the beveled faces 77 the spring 74 draws the rear extensions of the arms (59 and 71 together causing the stack lifters 7 O and 7 0 to move inwardly a suliicient distance to raise all but they lowermost end which is thus cut out and fed into the turret upon the subsequent inward movement of saidslide.

T have provided means to prevent operation of the end feeding mechanism just described in the event that a gasket is not po sitioned in the turret so as to be applied to such end in the normal timed operation of the different parts. This mechanism coniprises an arm 82 having at its outer end a finger 83 and normally held at a distance above the arms 69 and 71 by a slidable support 8t and a latch member 85 engaging a pin 86 extending through the upper part of said member 84-. The arm 82 is freely pivoted at 87 and is sustained in its elevated position merely by the support 8 1. Secured to the arms 69 and 71 are inwardly project ing lugs 88 and 89 adapted to engage the finger 83 when the arm 82 drops to its lower or operative position. To effect such movement of the arm 82 I provide a magnet 91 held by a rod 92 secured in a casing 93 by means of nuts 9% and 95. This magnet is positioned near the latch 85 and when energized draws said latch from beneath the pin 86, allowing the support 84 to drop, which in turn permits the finger 83 to be carried between the lugs 88 and 89 to prevent operation of the feeding device to separate a can end from a stack.

To energize the magnet 91 an electric circuit is provided comprising a wire 96 con nected by a post 97 with a wire 98 which is secured to a post 99 in an insulated contact member 101, extending into a groove 102 extending about the under side of the turret 11. A contact pin 103 extends downwardly from a horizontally positioned rod 101 secured in a vertically extending rod 105 adjustably secured in an arm 106 which is slidable on another vertical rod 107 and adapted to be raised and lowered through the in strumentality of a die mounting 111 carrying the die which operates upon the blank at the next preceding station. The current is transmitted from the contact pin 103 through the machine and through a wire 112 secured to the machine by a binding post 113 to a battery or generator (not shown) which is also connected with the' magnet 91 by a wire 113 through a binding post 11 1 and a wire 115. The contact member 101, as has heretofore been stated, extends into the groove 102 and is of such height as to reach practically the level at which the gasket 63 is supported on a ledge 110, being insulated from the machine by a fibre plate 117.

When the pin 103 is moved downwardly into the port 17 it forms a contact with the member 101 if no gasket be present to insulate it therefrom. Upon establishment of such contact the magnet 91 is energized and the latch 85 withdrawn from its supporting position. Upon breaking of this contact the magnet is deenergized and the latch 85 free to be restored to its supporting position. This is accomplished by means of a spring 118 secured in the magnet casing 03 and bearing upon the lower beveled bearing part 119 by which the latch 85 is pivotally secured to a pin 121.

The arm 78 is connected with a rod 122 by-means of a sleeve 123 and a pin 12a and is reciprocated by the feeding mechanism which actuates said arm 78. Upon upward movement of the rod 122, a screw 125 which extends upwardly from a link 126 comes into contact with the lower end of the support 8st and elevates it to position to permit engagement of a shoulder 127 of the latch 85 by the pin 86, the under side of this shoulder being beveled to permit upward move ment of said pin 80. The lower end of the arm 78 carries a roller 128 which rides in the groove 129 of a cam member 131 carried on the outer end of a shaft 132 which has hearings in the frame 12 and is rotated by a pinion 133 mes-hing with the gear 14:, this cam being provided to control the movement of the arm 78 whereby the restorative action just described is accomplished.

If a gasket be present at the detecting station, normal operation of the end feeding mechanism places an end in the turret beneath one of the ports 17 and the gasket is seated thereon at the next station by an upper seating die 131 and 135, these dies being operated through suitable connections by cams 136 and 13? carried respectively upon the upper and lower transverse shafts. An ejecting rod 138 secured in an arm 139 and actuated by the upper seating die operating mechanism is provided to knock out the lined can ends which fall into a suitable holder or conveyer.

It is thought that the invention and many of its attendant advantages will be understood from the foregoing description, and

it will be apparent that various changes may be made in the form, construction and arrangement of the parts without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.
