Specification of Letters Patent.

Patented Nov. 26, 1907.

To all whom it may concern:

Be it known that I, OTTO S. BEYER, a citizen of the United States of America, and a resident of East Rutherford, county of Bergen, and State of New Jersey, have invented certain new and useful Improvements in Sea'rning-ltiachines, of which the following is a specification.

My invention relates generally to seaming machines and has more particular reference to the gearing used in driving the different I parts of the machine and to the combination of parts and features of construction hereinafter set forth.

'Heretofore, it has been customary to have a plurality of seaming members mounted on the rotating seamer head so as to travel in an orbit around the work to be acted upon, the said seaming members further having a movement toward and away from the work at the proper periods so as to properly engage with or act upon the seam to be formed. In connection with this, it has generally been customary to have, an automatic feeding mechanism for the cans adapted to bring the said-cans successively into and out of position with regard to the chuck and seaming members, at the moment when the seaming members are in a position to admit the passage of the cans. In some cases, however, it is desirable to have a hand-fed machine and in order that the finished can may be removed by the operator, it is necessary that the movement of the seaming members toward and away from the work should cease while the said can is removed and after it is finished. It is obvious that this replacing of the can must be substantially at the moment when the seaming members are in the position farthest away from the work. The seaming members are therefore normally held awayfrom their operating position, and

are only actuated at will by the operator.

The seamer head, carrying the seaming member or members can, however, rotate continuously. In carrying out these objects, I provide the seamer head with a pinion for each seaming member which travels around or rotates with the said seamer head and which furthermore has an individual rotation around its own axis which acts to bring the seaming members into operating position. Means are provided for stoppmg the individual rotation of these pinions at will and substantially at the moment when the seaming members are farthest away from the work. The parts are so arranged that the said pinion or pinions makes one revolution around its own axis to a certain predeter mined number of revolutions of the seamer head. In this instance, the relation is 1 to 12, the pinion making one revolution around its own axis to 12 revolutions of the seamer head. This proportion .can of course be changed at will. To impart the necessary motion to this pinion or pinions, I provide a gear placed concentric with the seamer head and running at a speed slightly greater than the said seamer head, the relation being. in the present instance 12; of the said concentric gear to 12 revolutions of the "seamer head. This concentric gear is driven from a train of gears which preferably connect with a gear mounted on the spindle of the seamer head andrunning at the said speed of the seamer head. A clutch mechanism is interposed in the said train of gears suitably con trolled to throw the clutch in substantially at the same moment the can is clamped between the work supporter and the chuck. In the present instance, a treadle mechanism is used for this purpose.

A suitable locking means is used to maintain the parts in their working osition after they have beernmoved into t 1e same, and means are provided whereby the said locking means is unlatched or freed automatically so as to disengage the clutch with its cooperatlng means after a certain predetermined pe riod. In the resent instance, the arts are so arranged t lat after the seamer ead has made 12 revolutions and the pinion carried by the same has made one revolution around its own axis that the said clutch mechainsln' will be thrown out of engagement with its operating mechanism.

The means for stopping the individual rotation of the pinion around its own axis, consists in the present instance of a cam and a stop for preventing the rotation of the said also part y in section.

' the seaming members.

stop, however, has the effect of preventing the backward rotation of the pinion, the result being that the gear placed concentric with the seamer head and which is rotating at a speed slightly greater. than the said seamer head will be carried around at the same speed as the seamer head when the seaming operation ceases. When the clutch is thrown in again, the stop, cooperating With the cam carried by the pinion, will be withdrawn so as to allow the pinion to be rotated around its own axis and the diilerence in s eed between the scanner head and the gear p aced concentric with the same being relatively very small, there is no jar or shock in starting or stopping the machine at any time. 1

In the drawings 1 have'embodied my invention in a useful and preferred form without, however, wishing to be understood as limiting myself in any way to the construction therein set forth.

In the said drawings: Figure 1 is aside elevation of the machine embodying my in vention, partly in section. Fig. 2 is a lan' view of the under side of the chuck and seamer head showing three seaming members used in the present instance. Fig. 3 is a detail view of the seamer head, showing the cam and-stops for the pinion which actuates Fig. 4 is a sectional view on the line a:zc of Fig. 1. Fig. 5 is an enlarged detail view, partly in section, of the seamer head and adjacent elements. Fig. 5 is a detail view of the seaming member having two opposed conical deflecting rolls.

. Fig. 7 is a sectional detail view of the head and seaming members showing more particularly the means for moving the seeming members toward and away from the work. Fig. 8 is a detail view of one of the seaming members as 7 partly in section. Fig. 9 is another detail view of the seaming member 7 showing more particularly the means for moving the conical deflecting rolls toward and awe "from each other.

Similar characters of reference indicate corresponding parts in the different views.

1 indicates a frameworkof any suitable construction for properly supporting the various parts. p

2 indicates the seamer head which is suitably operated from the shaft 3 through the instrumentality of the miter gears t and 5.

The seamer head carries one or more seaming members as the case may be, but, is in the present instance provided with three seaming members c, 7 and 8 which include in part two opposed conical deflecting roll carried by the member 7. These seaming members may of course be constructed in any suitable way and may be caused to move into and out of seaming position in any suitable manner. Preferably, however. they contour of the said work.

This view is senses are provided with a contour carrier 96 pivoted on the head 2 in the usual manner on the studs 12.

Mounted on the contour carrier is a seaming carrier 13 which in turn carries the seaming tools. This arrangement could of course be reversed and the contour carrier mounted on the seaming carrier, in which instance the seaming tools would be carried by the contour carrier, the only requisite being that the seaming tqols partake o'r the motion of both carriers.

The contour carrier )0 will conveniently take the form of an arm having an extension 91 carrying the roller 9 adapted to travel in the cam 10 carried by the chuck 11. As the bers will be carried around with the same and will be caused to travel in an orbit around i the work to be acted upon parallel to the g in the present instance, where the work is square, the cam 10 will of course have a contour substantially identical with the contour of the can or work to be acted upon. The cam 10 is of course stationary with the work to be acted upon. The seaming carrier .13 will conveniently take the form or' a bell crank lever and is pivoted at 14 on the contourcarrier 90. This seaming carrier carries the seaming tools which in the present instance are in the form of rolls, the second member having two opposed conical deflecting rolls. Any suitable means can of course be provided for moving the seaming carrier toward and away from the work. In the present instance, it is constructed as follows: One end of the lever or seaming carrier 13 is connected with the plunger 92 sliding in the cylinder 93 in which is located the spring 94 for yielding to any unevenness in theseam. This tube is carried by a sliding member 95 provided with an ex 'ansion spring 96 which normally tends to lied the seaming member awayfrom the work. inside the contour carrier; is a spindle 97 carrying the pinion 16 at its upper end and the cam 15 at its lower end. Carried by the sliding member is a roller 98 with which the cam 15 is adapted to engage to move the seaming carrier toward the work. This construction is common to all three members. seaming member carries the crimping or curling roll 99, and the seaming carrier on the third seaming member carries the finishing roll 100, while the second seaming member carries two opposed conical deflecting rolls 101 and 102 respectively. 1

The foregoing describes the construction of the first and third seaming-members. The second seaming member, however, must in addition to the above means, he provided The seaming carrier on the first with a mechanism for moving the conical deflecting rolls toward and away from each other at the proper moment.

svnsee Pivoted on the seaming carrier, 13 is a straddling link 103 which carries the lower deflecting roll 102. 104 indicates a stud also mounted on the seaming carrier carrying the lowerarm 105 adapted to engage with the straddling link 103. .Mounted on the said stud 104 is an upper arm 106 which bears upon a portion of the contour carrier 90. When the seaming carrier moves in toward the work, the arm 106 will engage with the contour carrier 90 thereby causing the arm 165 to move the straddling link 103 and the roll 102 in an upward direction so as to move the said roll 102 up against the conical deflecting roll 101. Upon the return movement of the seaming carrier, the reverse action it ill take place.

As there are three seaming members in the present instance, there will of course be three pinions, one for each seaniin member, but

revolution around its own axis'of the pinion,

the concentric gear making 12%; revolutions during the'same period to impart this one revolution to the said pinion. It will of course be understood that if the concentric gear were drivenat the same speed as the seamer head, the pinion would not rotate inasmuch as'the'said pinion travels in an orbit around with the seamer head and at the same speed as the latter. The, said concentric gear 17 receives its motion in a uitable way from a train of gears including the

gears

18, 19, 20, and 21. The gears 19 and 20 are mounted on a sedarate spindle 22, the gear 19 being mounted fast and the gear 20 being mounted loose on the same. The gear 21 moves at the same speed as the seamer head and is mounted upon the spindle 24 which carries the said seamer head. A suitable clutch mechanism is interposed in the said train of gears consisting in this case of the clutch 25 mounted on the spindle 22 and adapted to engage with the gear 20 to cause the motion of the said gear to be imparted to the spindle 22 and thence to the othergears.

26 is the work supporter adapted to receive the can.

27 indicates a treadle, the motion of which is imparted throu h the rod 28 to the bell crank 29 connected to the loose collar 60 on the work supporter by means of link 61. The work supporter further carries the fixed sleeve 62 between which and the loose sleeve is interposed the spring 63. The bell crank 29 carries an arm 64 which is attached to the link '30 provided with the slot 65 at its free end in which plays the pin 66 of the bell crank 31. Mounted on this pin 66 is a latch 67 provided with a hook 68 engaging the pin 69 on the link 30. This latch is further provided with a projection 70 having a slot 71 in which the pin 72, stationaryon the frame work engages. Connectin with the bell crank 31 is a rod 32 exten in upward and mounted on the pin 73. carried by the forked member 35. This member 35 is pivoted on the stud 74 attached to'the bracket 75 on the framework, and is provided with two pro- .jections 76 and 77 betweeri which extends the arm 78 of the clutch lever 33 enga ing in the sleeve 34 of the clutch. This clutc lever 33 is likewise mounted loosely on the stud 74.

Mounted on the pivot 79 of the member 35 is a hook 36 which is adapted to en age with the ledge 80 on the bracket 75 to dock the parts when the treadle is depressed. A spring seated plun er 81 tends to push the lower end of the hook 36 outward at all times. Mounted on the pivot 82 of the bracket 75 is a bell crank 43 adapted to move the sleeve 42 downward by means of the lever 44 pivoted on the bell crank 43 and resting on the top of the hook 36. The pin ion 16 is provided with the cam 37 with which engages the stop 38 in the-notch 39 of the said cam after it has made one revolution around its own axis. This stop releases the cam and thereby the pinion by.

connections from the sleeve42 consisting of the rod 41 attached to the said sleeve 42 by means of the screws 84. Rod 41 engages at its lower end a lever 40 which in turn engages with the stop 38. The back stop 45 is also provided to engage with the notch 46 of the cam 37 to prevent the pinion from turning backwards as otherwise might be the case.

When itis desired to seam a can, the said can is placed upon the work supporter and the treadl depressed, thereby lifting the work supporter and clamping the can. Throu h the instrumcntality of the link 30, the rod 3 and lifting the hook 36 up on the ledge 80 at the same time throwing the stop 38 out of en agement with the notch 39 of the cam 37.

wing to the construction of the link 30 with the slot 65, the can is caused to be clamped sli htly in advance of the throwing in of the cTutch and the beginning of the seaming operation. The movement of this link 30 causes the latch 67 to turnaround the pin 66 by reason of the pin 72 in the slot the member 35 pushes against the arm 78 of the clutch lever 34 moving the clutch in.

2 is lifted throwing the clutch 25 in en the rod is thus elevated, the projection? 7 on &

As the member 35 swings around the pivot 74, the hook 36 is lifted up and the spring seated pin 81 normally pressing the lower end of the hook outward, will cause the said hook to engage properly with the ledge 80 on the bracket locking the parts. The projection 77 is provided with a' spring seated plunger 85 so as to take up any discrepancy in the movement of the parts between the clutch 25 and hook 36. The throwing out of the stop 38 releases the pinion 16 and the clutch 25 through the train of gears imparts to it an individual rotation around its own axis whereby the seaming members successively move in toward the can. and scam the same. After the said pinion 16 has made one revolution, the stop 38 automatically acts through the lever 40, rod 41, sleeve 42, bell crank 43, and lever 44, pushing the hook 36 off the ledge 80, the downward movement of the parts connected thereto beingfacilitated by means of the spring seated plunger 86 on the bracket 75 acting against a portion of the member 35 so that the release is instantaneous. The member 35 being thus turned around the pivot 74, the projection 76 engages with the arm 78 throwing the clutch 25 out and pressing or pushing the rod 32 downward, thereby causing the work supporter to be released by reason of the latch 67 turnin around the pin 66 unhooking the hook 68 from engagement with the pin 69 and allowing the link 30 to move back.

The weight of the work su porter will generally be suificient to cause t e return movement when released but the spring 63 also assists in moving it back or down. This release is accomplished substantially at the moment when the seaming members are farand in the same direction.

thest away from the work. The back stop prevents the rotation of the pinion in the opposite direction as it travels in an orbit around with the seamer head and at the same speed with the same, and the concentric gear from which it receives its motion no longer being driven from its train of gears will rotate at the same speed as the seamer head If several seaming members are used, each of the said seaming members will be provided with a pinion, but it is only necessary to have a cam, a stop, and back stop on one of the said pinions.

The specific construction of the seaming members is not claimed in this application, as it has been made the subject matter of other applications by me Ser. No. 186,602,
