To all whom it may coacem:

Be it lrnown that 1, Jonas F. TonNoUisT, a citizen of the llnited States, resident of St. Paul, county of ltamsey, State of Minnesota, have invented certain new and useful lmprovements in Capping Machines, of which the following is a specification. A

The object of my invention is to provide a machine of simple,compact construction which will attach and clinch caps, usually of metal, previously formed and positioned, to the necks of cans and other containers, and which will. perform this work rapidly and efiiciently while the containers are traveling continuously through the machine.

My invention consists in certain constructions and combinations, all as hereinafter described and particularly pointed out in the claims, having reference to the accompanying drawinfi forming part of the specification, in whic Figure 1 is a front view of a machine constructed according to my invention, showing the operating parts in position just before the final pressure is applied to the cap in the capping operation.

Figures 11 and show a modification'of the device for operating the cap clinching means,

sprocket 27 Figures 16 and 17 illustrate the methods of clinching or securing the cap to the neck of the container:

in the drawings, 10 represents the main supporting frame of the machine, which;may be of any suitable construction and to which is secured a table or plate 11 upon which the cans or containers to be capped are conveyed from the filling to the capping machine by means of a conveyer chain 12. This chain is provided with horizontal lugs 13, between which the containers are delivered and which convey the containers continua ously over the table 11 to the capping mechanism. The chain 12 may be driven from any suitable source of power, but l have shown'a driving shaft 14: mounted in bear ings in a frame 15 adjustably secured to the main frame 10. A vertical shaft 15 is mounted in bearings 15 and carries a bevel gear 15 slidably splined on the shaft 15 and in mesh with abevel gear 15 on the shaft 141. A sprocket 15 secured on the vertical shaft 15*, carries the feeding chain 12. which runs over another sprocket (not The nuain driving shaft 17 of the ma chine is mounted in bearings 18 on the frame 15 which is adjustaloly secured to the frame 10 by means of screws ut studs 19 and 20 in slots 21 and 22; (Figures 1, 3 and 5.) A threaded rod 23. having collars M and an operating handle 25 is loosely mounted in a boss of the frame 10 and its threaded portion engages an internally threaded lug 26 upon the frame 15. By turning the handle 25. the frame 15 may be either raised or lowered for the purpose of adjusting the machine to different sizes of containers. All the operating parts except the feeding chain 12 are mounted upon the adjustable frame 15, and the shaft 1t, from which the feeding chain 12 derlves motion, is driven from the main shaft 17 by means of a driving uponsaid shaft 17, a chain Ft engaging said sprocket 27 and also a sproclret 29, loosely mounted upon a stud 30 and having an integral pinion 31 meshing with a gear 32 keyed to the shaft 14. As this shaft 14 and the stud 30 are mounted on the adjustable frame 15, their relative position is therefore not effected by the adjustment of this frame relative to the frame 10. The driving shaft 17 carries a driving pulley 33 and also a cam wheel 34 and the entire capping mechanism is operated through the medium of this cam wheel. A plate 35 slides horizontally in V-guideways 36 on the frame 15, (see Figures 2 and 5) and a plate 37 slides vertically in V-guideways 38 in the plate 35. (See Figures 8 and 9.) The horizontal movement of the plate 35 is induced by means of a crank pin 39 secured to the cam wheel 34 and engaging a connecting rod 40, pivotally connected to the plate 35 by a stud 41 (see Figures 1, 3 and 7). This stud is preferably made adjustable in a slot 42 in order to adjust the capping mechanism carried by the plate 35 to the proper position relative to the cans, as they are brought in place for the capping operation by the feeding chain 12.

The stud 41 is secured in the desired place in the slot 42 by means of a clamping nut 43 and a shoulder 44. The vertical movement of the plate 37 in the plate 35 is induced by the vertical swing of the connecting rod 40, acting through a pin 45, secured in the plate 37 and projecting into a slot 46 in the connecting rod 40. (See Figures 2 and 3.) A bearing block 47 is preferably provided on the pin 45 to reduce its wear in the slot 46 and the slot permits the pin 45 to change position in the rod 40 when the plate 35 is adjusted as above described. As the cam wheel 34 is rotated. the plate 35 is given a horizontal, reciprocating movement and the plate 37 both a horlzontal and vertical reciprocating'movement. The horizontal movement of the plates closely synchronizes in speed and direction with the movement of the feeding chain 12 during the period when the crank pin 39 is at the lower portion of its travel, as shown in Figure 3, and the vertical movement of the plate 37 controls and mainly effects the capping operation during this period. A cylinder or barrel 48 having slots 48* is secured to a flange 49 of theplate 37, in which barrel is located a sleeve 50, having at its lower end a flange 51, upon which is supported a series of depending segmental clincher blocks 52. These blocks are provided with inside beveled edges 53, adapted to move under the flange 54 of the cap 55, and under the shoulder 56 of the neck A of the container B, as shown in Figure 12. The upper part of the neck A above the shoulder-56 is slightly beveled as shown partlcularlv in Figures 16 and 17 and the cap 55 1s placel loosely on the beveled surface. The blocks 52 are loosely supported on the flange 5 and are normally held in a lowered position by the sleeve 50, and separated as shown in Figure 8 by coil springs 57. In this position an inclined shoulder or cam 58 on the periphery of the blocks is positioned just below the lower edge of the barrel 48.- When the barrel 48 is forced downward over the rags 58 the lower edges 53 are moved inward or towards the center of the neck of the container. When the blocks are thus moved inward their beveled inner surfaces form a conical die under the lower or free edge of the cap. A plunger 59, having a slotted head 59, is mounted in the sleeve 50 and its lower threaded end is provided with a hardened steel presser block 60.

pin 61 passes through the slotted head 59 of-the plunger 59 and a toggle link 62, having an upper toggle joint connection at 63 with a toggle block 64, embraces this pin with its lower slotted end. A toggle shaft 66 keyed to the toggle block 64 passes loosely through the sleeve 50 and the lower end of a link 67 and is also keyed to a rocker arm 68. The link 67 extends upwards and is pivotally and adjustably connected to a slotted cam arm 69 by means of a shouldered stud 70 passing through the arm 69 and an eccentric 71 in the link 67.

The eccentric 71 is preferably integral with an adjusting plate 72 having a series of radially arranged holes 73, (see Figure 1) and a pin 74 in the link 67 is adapted to engage any one of these holes and lock the plate in any desired position. By removing a lock nut 75 on the stud 70 the plate 72 may be disengaged from the pin 74, and the cocentric 71 may then be turned around to effect the vertical adjustment of the capping mechanism with respect to the neck A of the container 'B after which the parts will be secured in the adjusted position by the pin 74 and lock nut 75. The cam arm 69 has pivotal connection to theplate 35 at 76 and a pin 77 having a collar 77 projecting from the plate 37 into a slot 78 in the cam arm (Figure 2) by which the vertical movement of the capping sleeve 50 is delayed and controlled. The uniform. vertically reciprocating-motion of the plate 37 and barrel 48 is thereby converted into an irregular intermittent movement of the capping sleeve 50 and plunger 59 to effect the proper timing of the co-operating parts in the capping operation. as willhereinafter be more fully set forth. The rocking of the shaft 66 to cause the toggle action of the capping sleeve and plunger as heretofore described is effected in proper sequence of operation as follows:

Depending arms 79 and 79, integral with a hub 7 (Figure 4). are pivoted at 80 to the frame 15 and the arm 79 is provided with a roller 81 and the arm 79 with an adjusting slot 82. as shown in Figures 1 and 3. The roller 81 is held against the periphery or face of the cam wheel 34 by a ten- Ill) llll) sion spring 88 and a cut-away poition 8A of the face of the cam wheel, terminating in a rather abrupt shoulder 85, imparts intermittent swinging, motion to the arms 79 and 79 as the cam wheel rotates. A cam arm 89 is adjustably pivoted to the arm '79 in the slot 82 and is secured in the adjust/ed position by a shouldered bolt 87 and clamping nut 88 similar in constrnctiongto that shown in Figure 7. A longitudinal slot 89 having a central cam portion 99 (see Figure 13) is provided in the cam arm 89 and a pair of rollers 91, fastened to the rocker arm 68., on the toggle shaft 88, project into the slot 89. As the cam wheel 3t rotates, the weight of the arm 79, aided by the tension of the spring 83, keeps the roller 81 with considerable force against the annular face of the cam wheel, and in this position, as shown in Figures 1, 2 and 13, the toggle block 941 depresses the pin 91 and exerts a downward pressure on the plunger 59. When, however, the roller 81 passes into the cut-away or depressed portion 8t of the wheel, the cam arm 86 and toggle block (it will assume the position shown in Figure 8,

and the toggle pressure is released from the pin 81. This pressure is properly timed, by the location of the shoulder 85 on the cam wheel 34, to occur immediately after the blocks 52 are moved inward under the edge 54 of the cap 55 on the neck of the container B. Y

The reaction of the toggle members also exerts an upward pressure through the shaft 96 (Figures 2 and 8) on the sleeve 59, and the blocks 52 carried by said sleeve, there being suflicient looseness in the parts to permit the straightening out of the toggle members to create an upward pull on the sleeve 59, and the blocks 52*, thereby causing the blocks 52 to exert an upward pressure, opposing the downward pressure of the plunger. 'llhis action tends to balance the pressures on the cap and neck of the container. At the same time the upward pressure of the blocks 52 assists in closely and firmly clamping the lower edge of the cap against the shoulder on the neck of the container (Figure 17). V a

The containers B, being in the present instance preferably of the form shown in Figures and 13, are, as above described, conveyed from a suitable filling machine to the capping machine by the chain 12. ll prefer to have the containers pass under a chute 91 (see Figure 12) through which the caps 55 are delivered in the proper inclined position. The neck A of the container on gages, with this arrangement, the lower protruding portion of the flange 541 of the lower cap, and the cap dropping in place on the neck A, is partially pressed on the container bypassingunder an idler wheel pr roller 92, (Figure 152) p and is carried intliis posi tion under the capping mechanism. llhe caps. are normally held in the chute 91 by a suitable friction device tnot shown) from which they are released when enga ed by the containers. Means are preferab y provided for guiding, grippingg and holding the container firmly in positionmvhile traveling with the chain 18 during the capping operation, as follows:

Referring to Figures, 1, 5, 8 and 19, "converging guide plates 98 and. 93, engaging the top of the containers, are secured to the frame by meansof brackets 94, and are preferably provided with an upward flan mg receiving end 91. A depending gripper arm 95 is pivoted to the plate 37 at 98, and

is connected at 95 to a link arm 97 which in turn is connected at 98 to a gripper arm 98, pivoted to the plate 37 at 99. The link arm 97 is connected to the gripper arms 95 and 98 so that a movement of the link arm to the right will separate the gripping arms and a movement to the left will close the arms, and these movements are effected by means of an upwardly projecting arm 191 integral with the link arm 97 and having a cam slot 192 in which is located a pin 193. This pin is connected to the plate 85. The vertical movement of the plate 87 causes the cam slot in the arm 191 to throw the link arm 97 horizontally, when the pin 193 passes the offset portion 191 in the slot 192, thus either opening or closing the gripper arms 95 and 98. ll prefer to provide a cushion for the container and gripper contact, and for this purpose the pin 198 is not fastened directly to the plate 85 but to 'aswinging angle plate 195 pivoted to the plate at 196 and normally'held against the edge of the plate 85 by a coilspring 197, adjustable upon a rod 198, as to tension, by a threaded nut 199, as shown in Figures 8 and 9. When the gripper arms press against thecontaiiner. the

plate 105 will swing more or less on its pivot, according to any irregularities there may be in the size or forms of the containers and by depressing the spring 197 will tension the containers firmly between the s P v n the operation of the machine, the arrival under the capping mechanism of a container B with a capon the neck thereof, as above described, is timed to coincide with a diagonally downward movement of the plate 37, the horizontal movement of the plate 35 together. with the downward vertical movement of the plate 37-, giving this resultant diagonal movement to said plate '37 and the parts carried thereby. At this time, and slightly before the parts resume the position shown in Figure 1,,the gripper arms 95 and 98 are in the open and elevated position .shown inFig-ure 8, and as the plate 37 descends the grippers 95, 98, close down over the sides of the container, and, by the clamping action of the link arm 97, the containeris made to travel horizontally with the plate 37, preferably, at certain points, a little faster than the chain 12. The cap has now passed under the sleeve 50 carrying the blocks 52, and as the plate 37 descends these blocks move downward and inward towards the neck of the container and under the free edge of the cap 55, (Figures 16 and 17). During the downward movement of the plate 37, as shown in Figures 2, 3 and 12,

. the blocks 52 are, as already stated, brought downward and inward and under the flange of the cap 55. and these blocks are held in that position by the cam arm 69 as shown in Figure 8 of the drawings. By a further downward motion of the plate 37 the barrel 48 is brought down to close the blocks 52 around the neck of the container. At this point the plunger 59 is forced down onto the cap by the toggle joint 64, which forces the cap downward, causing its free edge to ride over the conical die seat formed by the inner surfaces of the blocks 52. At the same time the straightening out of the toggle members causes the sleeve 50 to be pulled upward slightly thereby pressing the jaws or blocks 52 upward counteracting the downward pressure of the plunger, thereby balancing the pressure upon the upper and lower sides of the shoulder around the neck of the container, and at the same time aiding in closely pressing the flange of the cap into a snug and permanent position beneath the shoulder of the container. The upward pressure exerted by the jaws or blocks 52, therefore,counteracts and balances the downward pressure exerted by the plunger, while at the same time these two opposite pressures squeeze the edge of the cap and its flange so as to make a very efi'ective seal around the neck of the container. The edge of the cap is thereby turned inward close to the neck of the container, which firmly secures or clinches the cap in place thereon, making a smooth joint between the edge of the cap and the neck of the container around which I said cap is closed (see Figure 17).

As shown in Figures 1 and 8, the toggle members have again been released after the clinching of the cap is completed. On further rotation of the cam wheel 34 the plate 37. still moving horizontally, is gradually raised. first to release the clinching blocks from the container while the pin 77 traverses the slot 78 in the cam arm 69'. When thereafter the pin strikes the curve of the cam in the arm 69, the clinchers parts, operating in the barrel 48, will be raised away from the container, thereby permitting the container to continue its travel onthe table 10. While the crank pin 39 of the cam wheel 34 completes the upper arc of its travel, another container is brought in position by the traveling chain 12 to be grasped by the grlpper arms 95 and 98 and the operation will be repeated.

In Figures 14 and 15 I have shown a modification in which I substitute the straight bar 120 for cam bar 86, and dispense ovith the toggle arrangement located at the upper end of the plunger 59. As here shown the bar 120 is substituted for the bar 86 having cam slots therein. This bar passes between the stud 61 and the shaft 66, as shown in Figures 14 and 15 of the drawing. The bar 120 is provided with the shoulders 121 so that when the bar is moved horizontally the plunger 59 is caused to descend and the sleeve 50 to which the jaws or blocks 52 are connected is moved upward slightly, the action being similar to that obtained with the toggle joint already described. This device accomplishes the same result as the toggle joint device, but is somewhat simpler in construction, and may in some instances be preferable in use.

I do not limit myself to the use of this mechanism for the application of caps to the form of containers shown in the drawings, The containers here shown are formed of sheet metal and are particularly adapted for holding syrup, and the machine has been designed particularly for applying caps to these containers. It is obvious, however, that without any material modifications the machine may be adapted for applying caps to other forms of containers or to containers formed of other materials.

The details of the construction may be modified in many particulars without departing from my invention.
