MACl-IlNE FOR SEAMING SHEET=METAL BOXES.
SPECIFICATION formingpart of Letters Patent No. 733,678, dated July 14, 1903.
Application filed September 9, 1902- Serial No. 122,716. (No model.)
To all whom it may concern:
Be it kn own that I, HENRIK J R-GEN REIN- ERT, engineer, asubject of the King of Sweden and Norway, residing at Ovre Strandgade 105, Stavanger, Norway, have invented certain new and useful Improvements in Machines for Seaming Sheet-Metal Boxes, of which the following is a specification.
This invention relates to a machine for seaming cylindrical and other sheet-metal boxes.
The object of my invention is to provide a simple structure whereby cans of cylindrical as well as cans of irregular shape may be seamed.
In the accompanying drawings, Figure l is a sectional side elevation of the machine, the section being taken through the central plane of the spindle; and Fig 2 is a sectional plan view thereof, the section being taken on the line X Y, Fig. 1.
S is the machine-frame, and A A are the usual clampingdisks, adapted to grip the sheet-metal box during the seaming operation. The spindle B, upon which the upper clamping-disk is secured, is mounted at its upper end in the frame, While its lower end is inclosed by a sleeve 0, carrying two rollerholders D D. These holders are pivoted at their upper ends to pins I I and are held by springs in an inclined position. The seaming-rollers are mounted in the lower ends of the holders D.
E is a steel ring encircling the upper part of the roller-holders, the said ring being of such shape that when the sleeve and the holders are rotated it holds the rollers in cont-act with the edge of the box. I have shown a four-sided box with rounded corners. The ring E can be raised and lowered in the vertical guide G by means of a The ring E is attached to the ring K, and this latter is provided with bracket, which slides in ways E on the frames. The lever F is on a rock-shaft F, journaled in the frame and having an arm F connected to the ring K. By this connection the ring K, with the ring E, may be raised and In the drawings lowered to control the position of the holders D. 1
The sleeve G, with the holders D, is rotated by the pulley H, and as the roller-holders are held by means of the springs against the ring E they are caused to follow the inner periphery of the said ring, and consequently the periphery of the box. When now thering E is moved downward by means of the lever F, the holders D D are actuated in such a manner that the rollers are moved against the edge of the box, and when the sleeve 0 is rotated by means of the pulley H the box is seamed.
By making the outer surface of one of the holders D (in the drawings that shown to the left) inclined at its upper part and then vertical, while the corresponding surface of the other holder is wholly inclined, the work can be divided between the two rollers. Furthermore, more than two holders can be arranged upon the sleeve 0, if desired.
Having now described my invention, what I' claim as new, and desire to secure by Letters Patent, is=
1. In a machine for seaming circular and other sheet-metal boxes of the kind, wherein the movement of the seaming-rollers is regulated by holding the said rollers always in contact with the joint of the box during rotation, the combination of a rotary pulleydriven sleeve, a number of holders pivotally suspended in said sleeve and carrying at their lower ends seaming-rollers, and a slidable guide-ring, the inner edge of which being formed in accordance with the shape of the boX and bearing on the suspended holders in order to press the rollers inward against the edge of the box, said guide-ring being held from rotation with the holders and contacting directly with the holders so that they in rotation will follow the inner contour of the said ring.
2. In combination a sleeve with means for rotating the same, seaming-rollers, holders for the said rollers pivotally suspended from the sleeve, a ring surrounding the sleeve and holders of an internal shape corresponding to the exterior shape of the can to be seamed, a holders so that they in rotation will follow the IO sliding bracket connected to the said ring, inner contour of the said ring, substantially means for sliding the bracket with the ring as described.
vertically to cause the same to control the In witness whereof I have hereunto set my seaming-roller holders and springs interposed hand in presence of two witnesses.
between the holders and the sleeve for press- HENRIK J GRGEN REINERT. ing the holders outwardly against the ring, Witnesses:
said guide-ring being held from rotation with ALFRED N. ALFSEN,
the holders and contacting directly with the NIKOLAY SAWETEN.
