I Application filed March M1905. Serial No. 251.727-

To all it may concern:

Be it known that I, Orro 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 seaming-Machines, of which the following is a specification.

The present invention relates generally to seaming machines for joinin the ends or heads of cans to the bodies 0% the same,

and has more particular reference to the driving mechanism for operating the parts.

The object of the invention isto simplify the partsv as much'as possible and to reduce the number of driving gears and members necessary to properly effect the operation of the machine.

In machines of this character, it should be understood, that the seamer head or disk carrying the seaming members and the chuck or clamp for the work have a rotary motion one with reference to the other, and further that the seaming members should be given a movement toward and away from the work or can during a certain period of the seaming operation. In the present instance, the seamer head is rotated while the chuck or clamp for holding the work stands still. This arrangement could of course be reversed.

The work tobeacted upon will generally be round, thoughthe invention is susceptible of being modified to act on square or irregular shaped cans, and a modification showing this is depicted in the drawings and described liereinaiter.

- form a part 0 Preferably the machine is automatic throughout, an automatic feed being provided and the machine being continuously running, 'althou h this does not necessarily the broad scope of the invention. i

In carrying out the invention, the main improvement e'liected is in. dispensing with the extra shaft and gears carried by the same which are generally used in machines of this character to impart a diiierential speed to the seamer head with relation to the. seaming members. This is accomplished by mounting the transmission mechanism and driving means on a plurality of shafts, one within the other..

Another feature resides in the manner in which the Geneva stop and the means for lifting the work supporters as they successively come into upper clamp or chuck are operated from the driving means, the especial feature used being a shaft having universal joints. By this means the number of gears are also reduced and less care is necessary in centering the Geneva stop with relation to the driving means. The seaming members in themselves also embody new and useful improvements, relating especially to the adjustment of the different sizes of cans to be acted upon.

binations of parts will appear as the specification proceeds.

In the accompanying drawings these several improvements have in a suitable construction. It is obvious, however, that the particular means used to effect the various improvements may be varied without departing from the true nature and scope of the invention.

W 2 is the seamer head and 3 the seaming members.

4 is the chuck or clamp.

5 indicates a plurality of work supporters mounted on the rotatable dial 6 in a well known manner. The framework carries a bracket 7 supporting a hollow shaft 8 provided with suitable driving means such as the hollow pulley 9 to which motion is imparted by means of the belt 10 passing over the idlers 11 and receiving its motion from the shaft 12 carrying the pulley 13. The shaft 8 is provided with suitable means, in the'present instance the

cams

14 and 15, for causing the seaming members to move in and out in the usual manner. Mounted on the hollow pulley'9 is a'coneentrically disposed internal gear 16 with which meshes the eccentrically disposed external gear 17.

18 is a shaft located inside of the shaft 8 and carrying the seamer head 2. Mounted on this shaft'18 is a concentric member 19 in the present instance in the form of a disk, and means are provided whereby this disk or member 19 is driven from the eccentrically disposed external gear 17 preferably taking the form of a link 20 attached to the gear 17 and member 19 by means of the bolts or studs'21 aiid22. Located inside the shaft 18 is a spindle 23 carrying the chuck or clamp '4, the said spindle being supported in the bracket 24 of the framework.

Moving with. the pulley 9 is an upwardly extending hollow shaft 25 carrying the worm 26 meshing with the worm gear 27 mounted on the shaft 28 extending at right angles to the said shaft 25 and having at its outer end the bevel gear 29 meshing with another bevel gear 30 mounted on. the stud or shaft 31 car 1 ing the cam 32 with which the roller 33 of t e pivoted lever 34'engages. This pivoted lever engages at its other end the stem 35 which extends down through the. spindle 23 and has attached at its lower end the ,versal joints 40 and4l. the shaft 38 is mounted a cam 42 with which ejector 36. i

The rotatable dial 6 which rarrics the work supporters in the usual way is operated by means of a Geneva stop 37 mounted on the shaft 38 which receives its motion from the shaft 31 by means of the'rod 311 having uni- At the lower end of engages the roller 43 mounted on the pivoted arm 44 whose other end engages therod 45 ing members in the-present instance consist of the curling roll 48 and the finishing roll 49. The curling roll 48 is carried by bushing 50 having the bifurcated arm .51.

which engage a worm 54 carried by the socket 55 on the bushing 50.

On the end opposite to that'of the screw 56, there projects outside the socket 55 a portion of the spindle 57 on which the worm is mounted. I

' It will be understood that by this means the saiil bushing 50 and the roll 48 are locked to the spindle 52 so as to move with the same. When it is desired, however, to adjust the position of the said roll '48 so as to correspond The spindle i '52 has teeth 53 cut in said spindle with This socket 55. is provided with a screw 56 at one end WhlCl'i serves to tighten the worm 54 in position.

with different sizes of cans, the screw 56 is loosened and the portion 57 of the spindle carrying the worm 54 is turned thereby adjusting the position of the roll 48 with reference to the work to be acted upon. When thedesired adjustment has been obtained,

the screw 56 is tightened whereby the. roll 48 and bushing 50 are held locked to the said spindle 52. The said spindle 52 is turned or given a motion so as to cause the roll 48 to move toward and away from the work by any suitable means such' as theroller 58 fast on the said spindle 52 and adapted to engage withthe cam 14 on the shaft 8, and held up against the same by some suitable means as the spring 59. The finishing .roll 49 is constructed in substantially the same way and is operated from the cam 15, but is, in addition to the foregoing elements, provided with a yielding member which takes the form of a spring seated arm 60 attached with one end to the bifurcated arm 51 and extendin with its other end into the sleeve 61 carried y the socket 64 which in this instance is mounted on the spindle 70 independently ofthe bushing 65. The sleeve 61 is provided with a spring 62 which presses a ainst the said member 60 and against the bo lt 63 closing the end of the sleeve 61. This spring seated member is for the purpose of compensating for the unevenness of the can due to the longitudinal seam of the body of the-same so that when the finishing roll presses the Hammer seam home, it is enabled to recede a slight distance when passing over the longitudinal seam of the body.

In this instance the shaft 8 is provided with a pinion 89 meshing with two '-.1dlers 90, and 91 which, in turn, engage the pinions 67- and 68 mounted fast on the spindles 92. ,IAli the lower end of one of the spindies 92 there is. mounted a cam 71. Surrounding the spindle 92 is an eccentric bush- Ling 72 on which ismounted the arm 7 8 carry- 'ing" the roller 74 running in the stationary 5o cam 75 mounted on ,the chuck 4.. Pivotcd on this arm 73 is a bell crank 7 6 carrying the roll, in this instance'the curling roll, 77 at one end and connected at its other end to the rod "78 adjustably attached to the sliding block 79 carrying the roller 80 engaging with the cam 71 and rovidcd with a slot 81 into whichthe, em of the spindle 92 extends and normally tendingto hold the'roller 77 away K from the work by reason ofthe spring 82 so. .located'in said slot 81. It will be noted that the roller 74, engaging with the cam 75 is mounted eccentrically with relation to the :spindle 92. -j By this means a more steady 1 and even motion is efiected and less jarring B5 of the'parts takes place.

The construction of the" finishing roll 85 and the. parts-carrying the same is substantially identical with the construction of the roll 77 except-that in this instance the. rod 86 connecting" with the bell crank supporting the finishing roll is provided with a yielding connection with the sliding block operated by the cam on the lower end of the spindle 92. In this instance the rod 86 is provided with a lunger- 87 acting against the spring 88. his construction is to allow the finishing rollto'recede while passing over the side seam of the body of the can.
