CAN-SEAMING MACHINE.

SPECIFICATION forming part of Letters Patent No. 380,212, dated March 27I 1888.

Application filed August 30, 1887. Serial No. 248,266. (No model.)

To ZZ whom it may concern: y

3e it known that I, GEORGE W. LoRE, a cltlzen of the United States, and a resident of Dexter, in the county of Washtenaw and State 0f Michigan, have invented certain new and useful Improvements in Machines for Crimping and Double-Seaming Can Ends; and I do hereby declare that the following is afull, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, refer-V ence being had to the accompanying drawings, which form a part of this specification, and in which- Figure l is a central longitudinal vertical sectional View of my new and improved vmachine forcrimping and double-seeming the ends of sheet-metal cans, Snc. Fig. 2 is a perspective view taken from the lower end of the same. Fig. 3 is a longitudinal vertical central sectional view of a slightly-different form of my new and improved machine. Fig. 4 is a bottom plan view of the construction shown in Fig. 3, the rolls being shown in dotted lines. Fig. 5 is a vertical sectional view taken on line Y, :rw of Fig. 4.

View showinga slight modicatiomwhich will be hereinafter described; and Fig. 7 is an enlarged view in elevation of the machine, taken midway between rolls of two different kinds, and showing the means for rotating the sleeve.-

The same numerals of reference indicate corresponding parts in all the gures.

My invention consists in a new. and improved machine for crimping and doubleseaming the ends of sheetfmetal cans and other similar bodies; and my invention will be hereinafter fully described and claimed.

The great advantage of my invention is that it holds the sheet-metal can perfectly still, while the crimper or double seaming rolls The advantages of having the cans stand still are these. If the can is whirling around when the solderingiflux is put on, two-thirdsof this flux will fly or be thrown off by the centrifugal action, which to this extent defeats the object of putting on the soldering-ux, besides making'it more difficult to solder the caps on the cans. It also increases greatly the expense and the amount of soldering material or flux required. Where acid or soldering-salts are used they fly all over the clothes of the operator,as well as over the machine itself,and in closing paintcans ,and cans containing, other liquids the whirling can will discharge a part of its contents, making it very disagreeable for the op-` erator, besides wasting the material.

In my new and improved machine the cans stand still; hence the soldering-flux put on will stay where it is placed, and in sealing cans containing liquids none of their contents will escape and ily out, as the can is standing l perfectlystilhthe vcrimping or double-seaming rolls revolving around the can. A considerable amount of time is saved in placing the cans Referring to the several parts by their desig-f nating-numerals, 1 indicates the stationaryvertical shaft of my new and improved machine, as shown in Figs. l and 2, this stationary shaft being secured at its upper end in a frame, 2, of ordinary or usual construe'- tion, so that it can be readily raised or lowered vertically in order'to place-the can beneath its lower end or vto remove it when finished, and thus be retained in its adjusted position bymeans of a set-screw, l. end lof this shaft lis rigidly secured the centering-chuck 3, which rests upon thev topy of the can and holds it stationary in position. This stationary shaftl can be adj usted vertically bya suitable hand-lever of ordinary con- Upon the lowers struction; orthe-drive mechanism maybe arranged to raise it automatically as soon asv each can is nished.

drawings, for convenience of illustration. This sleeve lits and revolves upon the stationary shaft 1, and carries at its lower end the head in which the adjustable levers are secured which carry the crimping and double seaming rollers. This sleeve is rapidly revolved by means of any ordinary drive mechanism or belting from a source of power, a pulley and bolt, 4' and 4", respectively, for convenience, being shown. Upon the lower end of this re volving Isleeve is rigidly secured the head 5, which in Figs. 1 and 2 of the drawings is shown of a conical shape, with its concave side downward. This head is formed with the four radiating slots, 6, formed equidistant from each other, as shown, and in these radiating slots are adj ustably secured the levers 7 7, which carry on their lower ends the crimping or double-seaming rolls. These rolls are removably secured upon the lower ends of the adjustable levers 7 by the pivot-pins 8, and can be removed and changed, using rolls of different forms, according to the work to be performed, the shape of the can end, &c. In Figs. 1 and 2 these four levers are shown pivoted centrally upon the transverse pivots 9, the ends of which are held firmly against the lower side of the head 5 by the arms 10 10 of the bifurcated outer ends of adjusting-plates 11, each of which is lirmly held in its adj usted position against the lower side of the head 5, over that particular radial slot 6,by a screw, 12, which passes through the said slot and has a nut, 13, on its upper threaded end. It will be seen that by this construction and arrangement of parts, by looseningthe nuts 13, the levers can be adj usted in or out inthe slots 6 to suit the size of the cans to be operated upon.

Upon the revolving sleeve 4, above the head 5, are mounted two collars, 14 and 15, which can be slid up or down upon the said sleeve, but which revolve with the same, being formed in their bores with the grooves 16, in which fits arib or feather, 17, formed on the said sleeve, which serves to carry the said collars around with the sleeve, while at the same time permitting of their being adjusted up or down on the sleeve. Each ot' the said collars is formed with an exterior annular groove, 18, in which ft the ends of suitable levers, 19 20, of ordinary construction, for shifting the collars up and down on the revolving sleeve.

The projecting upper end ot' each of the four levers 7 has a longitudinal slot, 21, formed in it, and in each of the said slots is pivoted the depending lower end, 22, of a yoke, 23, in which is clamped the outer end of an arm, 24. The inner ends of the arm 24 of two opposite levers, 7, are pivoted between jaws 25 25, which are formed on the lower end of the lower adj usting-collar, 14, whilethe inner ends of the other two arms 24 24 of the other pair of opposite levers, 7' 7, are pivoted between jaws 26 26, which are formed on the lower ends of arms 27 27, which project downward from the lower end of the upper collar, 15,

passing through recesses 28 28 in the lower collar, 14, as shown more-clearlyin Figs. 6 and 7.

In operation a full can with its top placed in position is now inserted beneath the lower end of the stationary shaft 1, which is raised, and the said shaft being lowered, so that the centering-chuck 3 rests upon the cap of the can, by means of the lever 20 the collar 14 can be in a moment slid down on the sleeve 4, so as to swing the crimping-rolls 29 29 of the pair of opposite levers 7 7 into'operative position, so that as the can is held stationary by the stationary rod and the sleeve revolves and carries the said levers and rollers around with it, the rolls 29 29, which are formed with the narrow grooves 30 30, will roll up `the double seams or flanges of the cap and can end. These rolls are then drawn back by drawing up their collar 14 by its lever, and the other collar, 15, is then pushed down on the sleeve 4, so as to throw the other pair of opposite rolls, 7 7, in. These rolls are formed with a shallow wide groove, so as to flatten down the double seam, making a joint which is thoroughly water, oil, and air tight. These wide shallow grooves may be dispensed with in the rolls 7 and the rolls left plain, asshown in Fig. 7 of the drawings.

One sliding collar 14, with its levers, collars, and pair of rolls, can be dispensed with for double-seaming by using on the remaining pair of levers, 7, rolls with a narrow annular groove, like those shown at 29 29, but with a longer body below the said grooves. When only these two rollers are used, the shape of which is shown in Fig. 3 of the drawings, the rolls rst operate, like the'rolls 29, to roll up the double seams, when by raising the rolls the iiat body part 3l of these rolls will strike the rolled-up seam and flatten it down against the chuck 3 on the stationary shaft, which has been dropped for the last operation. These adjustments or movements can be performed automatically by employing suitable mechanism.

IIO

In Figs. 3, 4, 5, and 6 of the drawings I have shown the head 5 made dat and formed with the four radial slots 6. Through two of these slots pass the levers 7 7, which carry on their lower ends the crimping-rolls, and which are centrally pivoted on the pivot-pins 32, which are formed on the sides of slide-blocks 33, each of which blocks is formed with a longitudinal screw-threaded aperture, 34. Through these apertures pass the adjusting screws 35 35, which support these blocks, and which are swiveled at their inner ends to the hub 35 of the head 5, and by means of which thel said 1evers, with their rolls, can be adjusted in or out to suit the size of the cans to be operated upon. In this form the rolls themselves are removable and changeable, as in al1 forms of the machine.

36 indicates the sliding collar upon the revolving sleeve,which corresponds to the col lars shown in Figs. 1 and 2. It has arms 24,

Apitch or angle of the rolls can be adj ustedA Yare pivoted in the upper ends of the levers 7 7, and are held adj ustably therein by means of the set-screws 38 38. It will be seen that the by adjusting the angle of the levers .7 7 by means of these setfscrews 38, and the same obro ject is effected in the construction shown in Figs. l and 2 by means of the screws 39,which pass through the ends of the yokes 23 and have the nuts on their threaded ends.

Instead of the levers 7 7 being centrally pivoted, as shown in Figs. 3, 4, and 5, Ythey may be pivoted on the lower sideof the head 5on pivots 4l 4l, which are secured in the outer ends of adjustable plates 42, which are held adjustably in position by the bolts or screws 43,which pass entirely through the radial slots 6, and have their threaded lower ends screwed into threaded apertures 44 in the plates 42, as shown, their heads resting upon the upper side of the slotted head 5.

Through two opposite slots, 6, in the flat head 5 (shown in Figs.k 3, 4, and 5) pass the screws 45 45, which hold adj ustably in position the stems 46 46, to the lower ends of which are pivoted the rolls 47 47, which are set at an angle orinclination for the purpose of turning down the burr of the can 'ends before the other pair of rolls on the levers 7 7 `are brought down and in by the collar 14 and its operating-lever 2() to finish the seam.

I From the foregoing description, taken in connection with the accompanying drawings, the construction, operation, and advantages of my invention will be readily understood. It will be seen that my new andimproved machine is strong and comparatively simple in construction and exceedingly rapid and efcient in its operation. It can be run at a higher rate of speed than any other machine of its class, even up to one thousandnrevolutions. It is adjustableto the different sies of `4 5 cans, and an indefinite number of differentshaped rolls can be used, giving it a greater variation than any other machine made. vThe can being operatedV upon stands still, as before clearly described, thus giving themachine thegreat advantages heretofore set forth, over those in which the can is whirled around.

Havingthus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is

1. Ina machine for crimping and doubleseaming-can ends, the combination ofthe vertically-adjustable and non-rotatable rod having thecentering-plate secured upon its lower end, the revolving sleeve having the radiallyslotted head securedupon its lower end, the pivoted levers adjustable in said slots, a roll removably j ournaled upon the lower end of each of said levers, the sliding collar formed with the annular groove, the pivoted arms,andpiv oted adjustable yoke, and alever engaging the said groove for operating the collar. c

2. In a machine for crimping and doubleseaming can ends, the combination of the verticallyadjustable and non-rotatable rod having the centering-plate secured uponits lower end, the revolving sleeve having the radiallyslotted head secured upon its lower end, the bifurcatedadjustable plates, levers, each having a roll removably journaled upon its lower end, the sliding collar formed with the annular groove, the pivoted arms, and pivoted adj ustable yokes, and a lever for engaging said groovev for operating the collar.

In testimony that I claim the foregoing as my own I have hereunto aftixedvmy signature in presence of two witnesses.
