CHARLES L. HART, or BROOKLYN, NEW YORK.
CAN SEAMING AND CRIMPINGI MACHINE.
SPECIFICATION forming part of Letters Patent No. 324,318, dated August 11, 1885.
Application filed April 8, 1885.
To aZZ whom it may con/eerie:
Be it known that 1, CHARLES L. HART, of Brooklyn, Kings county, New York, have invented a new and useful Improvement in Can Seaming and Crimping Machines, of which the following is a specification.
My improvement applies more especially to that class of can crimping or seaming machines such as shown in the Patents N os'. 245,392 and 247,816, of August 9 and October 4,1881; and the object of my inventionis to construct a machine in which the operations of seaming the bottom of a sheet-metal article and curling or turning over the metal at the mouth thereof, termed wire-edging, may be carried on simultaneously; and to this end my invention consists in combining, with the face-plate, block, or table of a seamingmachine a means or mechanism for curling or turning over the metal at the mouth of such article, as hereinafter set forth.-
In the accompanying drawings, forming part of this specification, Figure 1 represents a front elevation of a double-seaming machine embodying my invention. Fig. 2 is a crosssection thereof on line 00 0c of Fig. 1. Figs. 3 and 4 represent an article in the different stages of manufacture, showing the operation of the seaming and curling or turning mechanisms on the said article. Fig. 5 shows the application of my invention to a horizontal single seamingmachine.
Referring to the drawings, A represents the article-supporting table or face-platc,rendered vertically adjustable by means of the stationary rack B, with which the pinion C, mounted in the table-supporting bracket D, engages, said pinion being operated by a hand-wheel, E, as shown. The said table is raised or low ered in its bracket by means'of the foot-lever E, pivoted to the base and connected to the lever F, mounted in the said bracket, the latter acting on the stem-shaft or projection G of said table.
The power for driving the machine is applied to pulley H on shaft I, which carries the chuck or disk K for engaging the bottom of the can or article to be completed. The bifurcated lever L, carrying the two grooved rolls M and N, for successively turning over and pressing down or flattening the double (No model.)
seam, is pivoted to the adjustable support 0, as indicated in Figs. 1 and 2.
The parts so far referred to are old, and the operation of seaming a can or other article by the mechanism shown is well-known and need not be herein specifically described.
As a means for curling or turning over the metal at the mouth of the can or other article, so as to give it the appearance of being wired, I mount in bearings on the tableA a series of suitably grooved rollers, 2, on which the article is placed and supported, and these rollers are so arrangedi. e., at such a distance from the center of the tablethat the said article will lie close to the inner flanges of said rollers. To adapt this means to cans of different diameters, I mount said rollers in radiallyadjustable supports or bearing-blocks 3, arranged to slide in undercut or equivalent grooves 4, formed in the table and held in place by means of headed screws 5 and clamp ing-nuts 6, or by any other suitable means. If desired, the journals of said rollers may be supported in spring-pressed bearings arranged in said bearing-blocks. (See Fig. 5.)
The operation of the machine is as follows: The mouth of the can or article is placed on the grooved rollers and the tableelevated to press the bottom of the can against the chuck or disk of the revolving shaft I. Power is now applied to pulley H to revolve said shaft and with it the can held by its chuck. The table, however, will not revolve, as it is prevented from turning'by a key or feather, d, on the bracket D, and hence as the mouth of the can rests on the grooved rollers 2, and is revolved over the same. by the rotation of the chuck K, the rollers are also caused to revolve against the edge of the can, and thus operate on or travel over all points of the mouth edge of the can. Any upward movement now of the table caused by depressing the foot-lever will exercise a pressure on the can and cause the rolls to act on the metal at the mouth thereof, to curl or turn it over outwardly onto itself, as indicated in Fig. 3. This pressure upward by the table is continued, the said table being gradually elevated more and more as the metal at the mouth of the can is curled over until the metal has returned upon itself and presents in crossscction the form illustrated in Fig. 4. \Vhile this operation at the mouth of the can is taking place the double seam is formed at the bottom of the can by the operation of the rolls M and N through manipulaticn of the lever L in the usual way, the roll M being first pressed up to the seam, as seen in Fig. 8, to curve in the metal, after which the roll N is pressed up to flatten down and complete the seam, as seen in Fig. 4..
In Fig. 5, which represents a horizontal singleseaming apparatus, the head or block A, which is also prevented from turning, is formed with dovetailed grooves 7 on its periphery, in which the blocks 3 slide, the latter being provided with journals 9, on which the grooved curling-rolls 2 are mounted. The said roll-carrying blocks are pressed forward by springs 11, so as to exert a yielding press are on the article, to preventthe latter from buckling, which might occur when thin sheet metal is employed, and to insure the even overturning of the edge. The can or other article is held between the chuck H of the mandrel and the curling-rolls of head A, the
arrows showing the direction of rotation of the mandrel and the direction of movement ot' head It, and the operation and result are substantially the same as in the case of Fig. 1. The seam is flattened by the roll, carried by lever T in the ordinary manner. It will therefore be seen that by this improvement in seaming'maehines I am enabled to produce the overturned curled or wire edge on the mouth of the can simultaneously with the formation of the bottom seam, and without requiring any appreciable additional thought or attention 011 the part of the operator from what is required to form the usual seam, and this result is accomplished by a very slight and inexpensive addition to the regular seaming-machine, which in no way interferes with its seaming functions, thus combining a sean1- ing and a wire-edge machine in one, and performing both actions at the same time, which greatly conduees to economy and ease of manipulation.
XVhat I claim as myinvention, and desire to secure by Letters Patent, is-
1. The combination, with the rotary chuck of a can-seaming machine, of a non-rotating face-plate, block, or table, and a series of rolls mounted on said face-plate, block, or table, substantially as described.
2. The combination, with the rotary chuel; of a caxrseamingmachine, of a non-rotating face plate, block, or table, and a series of grooved rolls mounted on said faceplate, block, or table, substantially as described.
3. The combination, with the non-rotating face-plate, block, or table oi. a can-seaming machine, of a series of rolls journaled in adjustable bearing blocks or supports mounted on said face-plate, substantially as described.
4. The combination, with the face-plate, block, or table of a can'seaming machine, of a series of rolls carried by movable bearings mounted on said face-plate, substantially as described.
5. The combination, with the lace-plate, block. or table provided with a series of 1a dial under cut grooves, of bearingblocks an ranged to slide in said grooves, eurlingrolls mounted in said blocks, and clani iiing means for holding said blocks stationary, substantially as described.
6. The combination, in a canseaming machine, of the mandrel and its chuck, with mechanism for seaming a can, and a face-plate or block provided with a series of curlingrolls for curling or turning over the metal at the mouth thereof, substantially as described.
7. The combination, in a canseaming machine, with the rotary chuck for revolving the can, and mechanism for seaming the bottom joints thereof, of a face-plate or table provided with a series of rolls on which the mouth-edge of the can rests, and means for pressing the rolls against the edge of the can, whereby the formation of the bottom seam and the curling over or wire-edging of the can may be performed sinniltaneously, substantially as herein set forth.
