TIN-OAN-SEAMING MACHINE.

To all whom it may concern:

Be it known that I, ANDREAS JENssEN, a subject of the King of Norway,residing at Stavanger, Norway, have invented certain new and useful Improvements in Tin-Can- Seaming Machines, of which the following is a specification.

In known tin can seamin machines the seaming rollers are usually cisposed on the free ends of levers and by them connected to guide rollers, which latter are controlled by a vertically movable guide ring and serve for gradually pressing the seaming rollers against the joint of the tin can. A mechanism serves for automatically reciprocating the said guide ring during the seaming of the can. This mechanism however, is comparatively complicated and requires the con stant attention of the attendant.

My invention relates to a new or improved mechanism in such machines, which is essentially simpler and renders the service easy, while the various parts of the machine are readily accessible for repair and replacement.

In the accompanying drawing: Figure 1 is an elevation of the novel tin can seaming machine, parts being shown in section; Fig. 2 is a horizontal section on an enlarged scale through the line I-I in Fig. l, seen from above; Fig. 3 is a horizontal section through the line IIIIII in Fig. 1, seen from below; Fig. 4 is a vertical cross sect-ion on an enlarged scale through the line II-II in Fig. 1, seen from left to right, and Fig. 5 is a vertical longitudinal section on an enlarged scale through an upper part of Fig. 1.

The frame of the machine consists of a pillar 1 with a lower arm 2 (Fig. 1), an upper arm 4, an annular projection 6 between them and a rear bracket 93. In a vertical sleeve 3 made integral with the lower arm 2, a spindle 12 is mounted to move longitudinally. This spindle 12 has a lower bore 12 (Fig. 4) and two opposite slots 17, through which passes a pin 16 fast in sleeve 3, whereby the spindle is prevented from turning. Into bore 12 is tapped a cover 13, through which passes an adjusting screw 14. To this screw is secured one end of a spring 15, the other end of which is connected to pin 16, whereby spindle 12 is pulled upward, so that pin 16 normally bears against the lower ends of slots 17 as shown in Fig. 4. To the upper end of the spindle Specification of Letters Patent, Application filed February 14, 1913., Serial 'N o. 748,274.

12, is fitted an exchangeable support 11 which is recessed for the reception of afilled can 25, the lid 26 of which is to be secured thereto.

In a sleeve 5 coaxial with sleeve Band made integral with arm '4, the upper reduced section of a stem 8 is fastened by means of a nut 7, so that said stem is prevented from turning. The lower end of stem 8 is reduced in diameter and made to taper so as to be received within a corresponding bore of an exchangeable head which is fastened to said stem by means of a wedge 9. The head 10 is adapted to engage in a recess of the lid 26 as shown and the parts 10, 11 serve for holding cover 26 firmly to can 25. On stem 8 is rotatably mounted the sleeve. 28 of a pulley or carrier 27 The latter may be r0- tated by a belt 29 running over idlers 30 that arecarried by spindle 95 and over pulleys 98. This pulley turns loosely on shaft- 94 and is made integral with a driving pulley 31 cooperating with a loose pulley 31 as usual.

The pulley 27 has two diametrically opposed upwardly projecting bearings 32 and 33 (Fig. 4) of different lengths, in which the sleeves 34, 35 of two arms 99, 100 are oscillatively mounted, said sleeves being held against longitudinal displacement by nuts 36, 37. From arms 99, 100 depend spindles 38, 39 carrying upper longitudinally movable guide rollers 42, 43. Below the latter, there are fast on spindles 38, 39, two seaming rollers 40,41. To the lower face of annulus 6 is secured a guide ring 61 (Fig. 3), the inner working edgeof which is concentric with can 25. Within sleeves 34, 35 are longitudinally movable shafts 46, 47 of different lengths. These shafts are 'provided with arms 44, which are apertured at their free ends forthe free passage of pins 38, 39. Arms 44, 45 are adapted to press from above on the guiding rollers 42, 43 and are connected by springs 59, (Fig.3) to pulley :27. In this way, the guiding rollers 42, 43 are held in contact with the rounded inner edgeof ring 61, so as to move the seaming rollers 40, 41 along the edges of can 25 and lid 26. To the upper end of sleeve 28 is fastened a gear wheel 62 which is thus rigidly connected to pulley .27. Between the gear wheel 62 and the web of the pulley 27 there is rotatablymounted on sleeve 28, a tubular member 54 provided with a pair of angular cam grooves 52, 53 and with an upper relatively fixed gear wheel 65. On the upper reduced ends of} shafts 16, 47 are rotat-j ably mounted sleeves 1S, fl9'held against axial movement by screws 57, 58. Sleeves 18, are threaded forengagement with correspondingly threaded disks 50, 51 and jam nuts 55, 56. ' Disks 50, 51 respectively engage with-their sharpened edges grooves ,52, 53 of member so as to vertically regrooves 1 'The'sleeve 5 is provided with a vertically disposed bearing 67, (Fig. 5), in which the hub 66 of a gear wheel 68 is free to rotate, such hub being held=-against-longitudinal ciprocate shafts 4:6, while following. said motion by a nut 68 and a threaded cap 69.

The gear wheel"68 meshes with the gear wheel 62 above mentioned, so that gear wheel 63 is continuously rotated from pulley 27. Within hub 66 is rotatably mounted the longitudinally movable hub 70 of another gear wheel 64:. The latter meshes I with the wheel 65 and has two diametrically opposed pins 71 adapted to engage corresponding sockets 63 of wheel 63 for coupling the wheels. In hub 70 is free to rotate a shaft 7 2 provided at the lower end with a head that supports the gear wheel 64-. At its upper end, there is tapped into shaft 72, a screw 74 which loosely passes through .a corresponding aperture of cap 69. The

'' hub 7 0 is shorter than hub 66 to accommodate a spring 75 that tends to lower wheel 64 out of engagement with wheel 68.

The sleeve 5 is provided with abracket 79 (Fig. 4e) in' which a shaft 78 is mounted to'rock. To the inner end of this shaft is fastened an arm 77 (Figs. 1 and 5), the free forkedend of which straddles an eye formed on screw 74: to which it is secured by a pintle'76. The outer end of shaft 78 carries a fast arm 81 and a loose hand lever 80. In

a boss 96 formed on the lower arm 2, a shaft 97 is mounted to rock, said shaft having a pair of relatively fixed arms 21, 22 (Fig. 4). These arms carry at their free'ends, a hori 'zontal shaft 20, which is pivotally connected i path of a tappet 88. -The latter is formed on a lever87 mounted to reckon a pin 86 carried by pulley 27. Lever 87 is by means of a spring 90 pressed-against the periphery of tubular member 5e: andis adapted to be engaged by'a lug" 85 provided on said member; r r

The four wheels 62, 63, G4, 65 form a differential gear for normally causing member 5a to rotate with a slow speed relatively to pulley 27 Assuming the two upper wheels 62, 63 to be alike in diameter and the lower wheels 64, 65 to be in the proportion of 10: 9, in other words assuming the wheels 62, 63 to have 45 teeth each and the wheels 64, 65 to have 50 and 15 teeth respectively, then the member 54 will make revolution on every revolution of pulley 27, that is revolution in advance of the pulley, so that after nine revolutions of the pulley, the operating member 5% will have made 1 revolutionrelatively to the pulley.

The machine operates as follows: Assume ing the seaming operation of a can to be completed and the parts to occupy the position shown in Fig. 5 in which wheel 64; is out of engagement with wheel 63. The operating member 54 is thus taken along by pulley 27 owing to the frictional contact therebetween and as the pulley 27 takes along with it the seaming rollers 40, 41, which now occupy their highest position, the attendant will be enabled to remove the seamed can. For this purpose, he grasps handle 18 and turns the hand lever back in the direction of arrow 19 (Fig. 1), so that the arms 21, 22 are swung downward in the direction of arrow 99. During this movement, the hand lever 80 slides on latch S 1 (Fig. 2) and thus releases the same, the latch now falling in behind the hand lever, whereby the arm 81 is coupled to the same. Spindle 12 is thus moved downward by link 24, thereby placing spring 15 under tension and lowering support 11, so that the seamed can may be removed and replaced by a can to be seamed. The attendant now releases handle 18 to cause spindle 12 to be raised by spring 15, so that the fresh can 25 and its lid 26 are forced against head 10. At the same time, the collar 23 of spindle 12 will by means of link 24 have swung arms 21, 22 upward, so that by means of shaft 20 and handle 18, thehand lever 80 is returned to the position shown in Fig. 1. During the forward movement of the hand lever 80, it has taken along arm 81 by latch 8-1,'so that arm 77 will raise lower wheel 61 until its pins 71 engage the sockets 63 of the upper gear wheel 63. In this way, these wheels are coupled, so that the operating member 54: commences to turn in the direction of the arrow 92 (Fig. 2) in advance of pulley 2. During this movement of member 54:, the conical guide rollers 12, 43 are, by disks 50, 51 gradually lowered while traveling along the inner edge of guidering 61, whereby the seaming rollers 10, 41 are gradually swung toward the can cover to properly perform the work. It is obvious that duringoperation the seaming rollers l0, :1 are independently moved inward for a certain distance, and that with the example stated, they are returned to their initial position after nine revolutions of pulley 27. Shortly before the end of this period, the lug 85 will encounter lever 87 (Fig. 2) and swing the latter outward, so that tappet 88 will swing the arm 89 of latch S t outward. Thus arm 81 will be re leased, so that spring is free to return arm 81 to the position shown in Fig. 1, while upon the subsequent disengagement of lug and lever 87, spring 90 will return said arm to its original position. At the same time, the spring 75 will lower gear wheel 64 to disconnect it from gear wheel 63, so that the rotation of the operating member 54: relatively to pulley 27 will cease and both of said parts will rotate in unison. The attendant thus ascertains that the seaming operation is completed, whereupon the can is removed by him in the manner previously described.

It is obvious that the attendant is enabled to stop the device for automatically pressing the seaming rollers 40, ll against the can at any moment without stopping the machine by properly manipulating hand lever 80.
