CAN-HEADING MACHINE.

To all whom it may concern:

lie it known that l, Fnnn WEGNER, of l airport,-in the county of Monroe and State of New York, have invented certain new and useful Improvements in Can-Heading Machines; and l do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the reference-numerals marked thereon.

The present invention relates to can heading machines of the type in which the cans are fed automatically to a seaming mechanism and it has for an object to provide a construction which shall be inexpensive to mai'uifacl ure, simple in its operation, and so constructed that destruction of the cans cannot occur.

view of a can before its head has been seamed thereon.

One of the present methods of canning fruits, vegetables and the like is to scam one of the can [heads directly to the body after the can has been filled, the can being of course presented to the seaming mechanism in an upright position to prevent the spilling of the. goods, and my present invention has been embodied in a'machine for operating on this type of cans; it being of course understood that it may be also embodied in any machine wherein the feeding of cans is desirable.

In the present embodiment the cans are rotated while being operated upon by a seaming mechanism which, in this instance, comprises a. pair of rollers l mounted on slides 2 that are moved away from the can by springs 8, and are moved toward the can by cam bars 4- swung on links 5 and operated by cams 6 on a cam shaft 8, the latter being dIlVG1l in any desirable manner.

The mechanism for rotating and holding the cans comprises a can rotating. member 9 and a rotary can support 10 arranged to turn about coincident and preferably vertical axes and one being movable toward the other. In the present instance the can rotating member 9 is carried by a. spindle 11 journaled on the frame 12 thatsup xn'ts the seaming'mechanism and this spindle may be driven by a belt 13 which after passing about pulleys 14 surrounds pulley 15 arranged on the'spindle.

The rotary can support 10 may be movable toward tl-e can rotating member and journaled on a vertically movable. support 16 that. is guided in bracket 17 on the frame 12. The lower end of the supoort may be provided with a roller 17 with which enga'gesa cam 1con a horizmital. shaft l9 jour naled in bearingsQO on frame 12, the cam being so formed that it elevates the vertically mov'able support 16 with the can support 10 a short time before the-seau'iing rollers 1 are moved toward the can, and" holds the rotary support in this 'lositidn until the seaming operation is completed. The cam shaft 19 may be driven from cam shaft 8 by a shaft 21. that has bevel gear connection with each of them.

The cans are fed automatically between the can rotatingmember and the rotary can support by a suitable feeding mechanism which preferably embodies a guide, supported by brackets 24 from frame 12, said guide comprising a supporting surface 22 and strips 23 or other means arranged above the surface on opposite sides thereof to overhang the heads on the lower end of the the guide, and preferably works between the strips 23 in a slot 25 formed in the bottom of the guide. The feeding device may: comprise a reciprocatory bar 26 guided in the slot and carrying a plurality of'dogs 27 yielding to pass the cans when the bar is moved in one direction and engaging the cans when the bar is moved in the other direction. Inthe present instance the bar is reduced at lntervals and the dogs are made of sheet metal bent to straddle the bar at the reduced portions, one end of each dog being pivoted at 28 and the other end being curved at 29 to conform to the outer wall of the can, the end of the curved portion being depressed to provide beveled portion 30, so that the dogs cannot engage within the rim at the bottom of the can.-

The feeding device maybe reciprocated in any suitablemanner but it is preferred to secure the bar to a slide 31 guided on the outer edges of the can guide and having a pitman 32 pivoted thereto at 33, the other end of the pitman being pivotally connected at 34 to a crank disk 35 that is carried on the upper end of a vertical shaft 36. Vertical shaft 36 is supported in bearings 37 and is geared to horizontal shaft 19 to re ceive motion therefrom.

In order to prevent the cans being fed too fast to the feeding device I employ stop deviceswhich project into the path of the cans and permit the feeding of only one after each complete reciprocation of the feeding device. 0110 of the devices s arrangcdm advance ofthe feeding device-and comprises a dog 38 which may be mounted on an oscillatory shaft 39 having an arm 40 extending therefrom and provided with a pin 41 that is engaged by an extension 42 on the feeding device, when the feeding device reaches each limit of its movement, thus causing the dog to swing to and from the path of the cans. A retarding device in the form of a shoe 39 moved in bracket 39* by a screw 39 holds the dog in either position. The other stop mechanism is arranged to engage each can after the latter has been moved to the path of the feeding device. This step mocha nism comprises two stops 42arranged on opposite sides of the can guide above the latter and prefer-ably 'in the form of horizontally swinging arms carried by rotary posts 43 which at their lower ends carry short arms 44 extending in opposite directionsandconnected by a link 45. The arms 42 are'normally held in stop positions by a spring 46, the link 45 serving to cause their simultaneous movement, and'a cam surface 47 on the crank disk '35 aco'tiperates with a long arm 48 on one of the posts 43 to move the arms 42 to a position permitting the movement of the can under the action of the feeding device, The arms 42 move from stop positions a short time prior to the feeding movement cf; the feeding device and move to stop position immediately after a can has passed them. Kn'order that the cans will die snugly 'againstthe stop 'I may provide two yielding stri s 49 secured at 50 at their outer ends "an converging toward their inner ends which are deflected at 51 to engage behind the cans after the latter have passed them.

After leaving the -last mentioned stop I mechanism, the cans successively pass a -series of return .stops on the guide to prevent the feeding device affecting the cans on its return movement. These return stops are in the form of dogs-52 arranged in pairs, the

members of each pair being positioned on opposite sides of the guides. 'The dogs are pivoted at- 53 beneath strips 23 and are pressed inwardly by springs 54, their inward movement being limited by shoulders 54fzwhich engage the outer edges of strips. The cans engage the inner edge of the dogs and move -'the latter outwardly out of the path of the former, on the forward movement of the feeding devices. The springs then move the dogs inwardly behind the cans.

While traveling along the guide the cans may pass beneath a yielding pressure device comprising a suitably supported plate 55 through which works a spring pressed presser bar 56. This pressure device serves to force the heads 0f the cans within the can bodies and hold them during the movement of the cans.

From the guide the cans are carried to the can rotating mechanism. This is effect ed by a feeding device preferably comprising a pair of can engaging jaws 57 mounted on opposite sides of the guide and movable toward and from the cans thereon. In this instance these jaws swing about yertiral axes and for this purpose are carried by arms 58 which are secured to posts 5!) turning on the slide 31, the lower ends of the posts being provided with arms (30 moved toward each other by a coil spring (ll. This spring causes the jaws to separate, and in llll) when the end of the feeding movement is movement of the order thatthey may be moved toward each other, I provide each arm with an upwardly extending pin or shoulder 62. These shoulders work throughslots 63 in slide '31 and each cotiperates with a pair of parallel guides 64 arranged on the bottom of the can guide and connected at one end by a fixed switch 65 and at its other end by a movable switch 66 pivoted at 67 and moved inwardly by a spring 68. As the jaws 57 with their operating parts are carried by the slide 31 and the guides 64 are carried by the can guide, it is apparent that the reciprocation of the slide causes the pins 62 to travel onv the guides 64, first on one and then on the other, the switches at the ends causing the shifting. This effects the movement of the jaws toward and from each other. The jaws move toward each other as the feeding bar begins the first part of the feeding movement, and are located slightly in advance of the last dog on the reciprocatory member so that when a can is engaged by the'jaws it will be moved away from the dog as shown in Fig. 4, thus preventing the engagement of the do with the bead on the bottom of the can, e ecting the release of the latter. The jaws release the can quickly reached this being effected by the spring acting on them. I

In order that the tops or heads of the cans will be in proper position when the can reaches the seaming mechanism I provide one of the jaws 57 with top positioning devices comprising two upwardly projecting fingers 69 which with a top positioning de vice 70 rigidly supported relatively to the feeding devices, causes the centering of the tops, the yielding pressure device causing them to enter the can bodies. The top positioning device 70 is preferably in the form of a flange or guide depending from the plate and having its forward end inclined at 70 in order to shift the tops during the feeding mechanism. Should the can top be displaced after it leaves the presser bar 56, it will, be again centered by a top positioning device 71- which is arranged in proximity to the can rotating mechanism, the arrangement of this positioning device being such that it is the same distance from the axis of the can rotating mechanism as the stops 69 when the jaws reach the end of their feeding move ment. I

It willnow be necessary general description of the operation of the machine as the operation of the several parts has been given. When the parts are m the position shown in Fig. 3, the reciprocating feeding member h s started on its feeding movement, the st ps42 have been moved out of the path of the cans and are about to move to stop position, the jaws 57 to give only a 'tion is simple,

are moving toward each other, and the stop 38 has been moved into the path of the can. As the end of the feeding movement is reached, stop 38 isdepressed to permit a can tov reach stop 42 and a can is presented to the seaming mechanism, the jaws moving to separate and release the can. On the return movement the stops 42 again move out of the path of the cans whilethe stop 38 moves into stop position. The seaming operation and the discharge of the finished can take place while the feeding mechanism is away from the seaming mechanism.

A. machine constructed in accordance with this invention is inexpensive to manufacture; its parts are constructed and arranged so that there is little liability that they will become broken or deranged; and the operanot requiring the attention of skilled labor.
