Application filed July 2 1995. Serial No. 270,898.

that principle, so as to distinguish it from other inventions.

My invention relates to improvements in machines designed to crimp the ends upon the cylindrical parts of tin cans and so der such ends thereto, the object being to pro vide a machine that will perform. both operations within itself in an expeditious and offective manner.

A further object is to provide a machine that will be readily adjustable, "i. e. that can be quickly adapted to crimp and solder the ends upon any desired size of can within the maximum limit of the particular machine. This last-named object has heretofore been only imperfectly realized although it is quite important, inasmuch as it makes possible the economical reduction of particular'sizes of can's in sma l quantities as the need therefor may arise. I

To the accomplishment of the above ends my invention consists of the combination, arrangement and structure of the various parts hereinafter described and fully set forth. in the claims.

The annexed drawings and the following description set forth in detail certain mechanism embodying the invention, such. disclosed means constituting but one of the various mechanical forms in which the principle of the invention may be used.

In said annexed drawings: Figure 1 represcnts a front elevation of my improved can crimping and soldering machine. plan view of the same. Fig. 3 represents a transverse horizontal cross-section of the machine as cut by a plane passing through the line 3- 3, Figs. 1 and 4. Fig. 4 represents an end view of the machine, as seen from the left of Figs. 1 and 2. Figs. 5 and 6 represent, partly in cross-section and partly in elevation, a can such as the machine is adapted to operate upon; Fig. 5 showing the parts of the can in their assembled condition just previ- 1 ous to passing through the can crimping de- Fig. 2 is a vice, while Fig. 6 shows the can after it has been there operated upon. Figs. 7, S and 9 represent upon an enlarged scale various views of the flexing device forming a feature of the machine; in said Fig. 7 is presented a plan view of such device when in its operative position, the can upon which it is operating being shown in dotted outline; in Fig. 8 the device is presented in similar operative position as viewed from the side, a can with the can-grip ing device beingshown in crosssection, whi e on the opposite side is shown the can-crimping device which, as will later appear, is designed to operate in conjunction with the fluxin device; and in Fig. 9 the same device is s 1own as cut by a plane perpendicular to the plane of the drawing and passing through the line 99, Fig. 8. Fig. 10 represents a vertical longitudinal crosssection of the step and journal block which supports the rotary-carrier spindle. Fig. 11 represents a vertical transverse cross-section of the same. Figs. 12, 13 and 14 are respectively a plan view, a side elevation, and a ver tical longitudinal cross-section of the improved form of soldering tool employed in the machine together with the actuating mechanism therefor. The position of the can being soldered is indicated in each case in dotted lines. Figs. 15, 16 and 17 are detail viewsof the solder feeding rolls with certain of the accessories thereto. Figs. 18 and 19 are detail views of the device designed to actuate such solder feeding rolls.

The principal elements of my machine are a series of devices respectively designed to perform the operations Of crimping thev ends on the can, applying flux to the joint between the can end and body, and then soldering such joint. A carrier advances the cans in succession into position to be operated upon by each of these devices, alternately moving them forward one stage, and then gripping and rotating those stationed before the-above devices. Coincidently with such gripping and rotating of certain of the cans, the several devices are simultaneously advanced to operate upon them, and are then retracted pending the advance of other cans. These various operative parts and devices composing the machine are mounted. in a suitable frame consisting of two upright standards A A resting upon a bed plateA, and two longitudinal arallel members or cross-bars B, B secure. at their ends to said standards; -All"such parts and devices are I actuated by a main drive shaft C, longitudinally disposed across the top of the frame and turning in bearings a (1 on the top of the standards A A respectively. Such main shaft may be connected to be driven by any suitable means as by 'a'drive pulley or gear at either end. Various secondary spindles C C C C andC vertically supported in cross-bars B, B or in arms project mg laterally therefrom are'connectod, as will hereinafter appear, to communicate the motion of maTm-s aft C to thevarious mcchanisms of the machine. As shown, Figs. 1, 2 and .3, .spindleCP- turns in bearings 12'' b and fie operatedby Worm gear wheels c; spindle I oplerated bythe-gear wheel 0 on spindle C4- w 'ich transmits its motion, by means of idlescribed s indies.

jouinaledin a block d which is mounted in an tarched step D and supported laterally at its upper end in bearing 6 oncross .bar B.

The toe d of the shaft D that fits into ournal blocktl is reduced in diameter, Figs. and 11, and turns upon a lenticular bearing d of hardened steel. The journal block d is vertically movable in a bore in the step D being yieldingly supported on a spring (1 held in a cup d similarly movablein the same bore. A lighter bar E, Fig. 1,'pivotally secured at one end E to bed plate A lies transwers'cly -'across such bed plate and passes end of the bar to a lever arm E on rock shaft "of said cup.

A. Rock slraftA",Figs. Land 3, turns in bearings a a and is actuated to raise and lower rod E by cam 0 on spindle C bearing against a roller c" mounted on one end of a sliding bar A", the other end of which is COD:

nected with shaft A by lever arm A. The :qr'ock shaft A" also serves to reci rocate one .of the soldering devices as wil be shown later; A turn-buckles, adapted to be secured by a lock-nut e affords a ready means of lengthcmngor shortening rod E whereby the height to which spindle l) is raised may be adjusted.

tjof the above de-v same? A spider, Figs. 2 and 3, secured to shaft D ata suitable distance above bed-plate supports a circular carrier f ame D on which the cans are borne 1nto p s t ion to be operated -mountedupon short vertical spindles 0" dis posed at equal distances around the circumference of the carrier frame D The number of such spindles and disks may be varied according to the size of the machine and the maximum; size of can to be operated upon. A set of disks is provided for each size of can, ofsuitable diameter and such length of boss (I as will raise the can high enough to be gripped bythe can-gripping device described later. To change from one size of can to another, differing only in height and not in diameter, the disks employed for the lower can may be raised for use with the shorter can by inserting suitable washers beween ofl'set d on the spindle and boss (i of the disk.

The shaft D with carrier frame D is adapted'to be intermittently rotated by means of a ratchetdevice, Figs. 1 and 2. This device comprises a ratchet wheel F feathered upon the'upper end of the shaft D and supported in a hanger F depending from cross bar B, and a pawl f pivotally mounted in a frame F held by two radial arms F F at a fixed distance from the ratchet wheel. Pawl f is 'held agamt the'ratchet wheel by a spring 2 se as to successively engage .notches f which are equal in number to the can supporting disks upon carrier frame I), and is actuated to rotate such ratchet wheel and connected carrier a distance equal tothe distance between successive notches and disks by means of rod F one end of which is attached to frame F, and the other eccentrically pivoted on the face of disk 0 secured to the lower end of vertical shaft C In order to avoid vibration of the carrier frame as well as to prevent it from being rotated too far under the impulse of the ratchet device, a suitable brake is provided. A preferable form of such brake is shown in Figs. 1 and 2 and consists of a broad strap or band D, attached. at one end. to a hired arm A projecting from a standard A and at the other to a lever' arm A mounted on a rock shaft A. Intehnediately of those points of attachment it bears against a portion of the periphery of the carrier 1). A second lever arm A", mounted on rock shaft A", and oper ated by the cam edge of disk 0 bearing against a roller (1. at such lever arms extremity, actuates lever arm A to alternately tighten and loosen the band D against carrier D Such loosening of the band is. timed to occur at the beginning of the intermittent rotation of the spider, and such tightening just as such rotation should cease.

By means of the mechanism above described, it is evident that a can upon the car-. rier frame successively occupies a number of positions of rest equal to the number of disks on such carrier. The devices designed to crimp the ends on the can, to a ply flux thereto, and then to solder themff accordingly dispose so to operate upon the can as it occupies certain of these positions. I have found it advantageous, for reasons that will appear, to position the crimping and fiuxing devicesto operate upon a can-at the same station, and to employ two separate soldering devices each adapted to solder one end only of a can at a time, that end being the lower one, and the distance between the two devices being sufiicient to allow an operative to invert the can after one end hasbeen soldered and before the second device is reached in the course of the carriers rota tion. The advantage gained by soldering both ends on the can in the" downward position, is that a tight joint is thereby more generallyassured since when molten solder is applied to the upper end of a can, the tendency is for it to flow, not into the joint as it should, but away. Accordingly can-gripping means are provided at three stations, or positions of rest, of a can in its regress through the machine, where the t ree different steps just described are performed, viz. crimping and fiuxing, soldering one end and soldering the other end. Such can-gripping means, Figs. 1 and 8, comprise simply disks, d removably secured to the lower ends of vertical spindles C, C" and C. These upper disks,

* just as the lower disks d on which the cans rest, are adapted to be readily removed and exchanged tosuit the size of can being operated upon. Upon the carrier being rotated to one of its ositions of rest, and then raised by means of ighter bar E,'- the three cans occupying stations beneath spindles C, C and C will be firmly clamped between lower disks d and u per disks al and at the same time rotated ii the spindles which, before indicated, are continuously driven by shaft C. While thus held and rotated the crimping, fluxing and soldering devices are actuated to perform their proper operations.

The crimping device comprises two disks p p Fig. 8, ad justably mounted upon a vertical s indle P which is rotatably held in frame 1 between set screws p 1). Frame P is secured to the end of a reciprocating bar P, Figs. 1 and 3, adapted to be actuated inwardly, toward the carrier frame by lever arm 3" mounted on rock shaft A and outwardly by a spring P Rock shaft A turns in bearings a" a" and is actuated by means of cam c' bearing against roller a mounted at one end of sliding bar A7, the other end of 'which is connected with such shaft A by being operated upon.

secured to the sleeves m m in such a poslmeans of a second lever arm A". A third lever arm S disposed similarly to lever arm P serves to reciprocate one of the soldering devices, as will be described later. The bar P may be lengthened and shortened to accommodate the crimping disks to cans of dif-v fercnt diameters by means of a hand wheel P, the manner in which such hand wheel opcrates being fully shown elsewhere in connection with the description of the soldering de vices. Nhile the use of such crimping disks in machines of this character isold, applicant desires to point out certain structural fea. tures of his disks whereby he obtains a more effective joint. It will be observed, Fig. 6, that a distinct outward flare has been given the end edges of the cylindrical portion of the can K, and that this flared portion is firmly 'clamped between the bent over edges 761 of the can ends. This obviously superior joint is produced by forming the can ends with the bent over edge 76 higher than the central portion K, Fig. 5, and providing the can-gripping disks with a groove around their outer edge into which such raised portion just fits, the can-crimping disks being provided with a projecting ridge conformingiwlth such groove. The application of the crimping disks, therefore,"not merely turns the bent over edge of the can, end against the side of the can, but, Fig. 8, presses together such bent over edge so as to firmly clamp the edge of the can side, which latter is given an outward flare.

The fiux applying device M is disposed so as to operate upon a can at the same time that the crimpin device is operating thereon. It consists, igs. 7, 8 and 9, of two rolls, m m, of felt or similar fibrous material, each secured to a suitable hub whereby it is rotatably mounted in the bifurcated end in of rock shaft m The rock shaft m is mounted in the sleeve m which in turn is adjustably secured on a vertical rod M. A lever arm m attached to the'end of shaft m that projects beyond the sleeve is actuated by a reciprocating bar M to rock such shaft m, the reciprocations of such bar being effected by means of a lever M, Fig. 1, pivoted at m and provided atone end with a roller m bearing against the lower cam face of disk 0 mounted on shaft C, and attached at the other end to bar M through the medium of a short chain M, The bifurcated end m" of the rock'shaf't m eccentrically mounted on the latter, so that upon the shaft being partially rotated, assuming the rolls to be in the vertical position shown in Fig. 1, such rolls will not only be turned to occupy a horizontal position, but will be simultaneously raised and thrust forward toward the can Acid cups 'mk" m are.

tion that the rolls dip therein in their vortical posltion and swing entirely free thereof when in the horizontal position. By sliding at some? the sleeves m m vertically along the rod M the rolls may be positioned to operate upon any height of can, while lateral adjustment to accommodate them to cans of different diameters is secured by swinging such sleeves on the same rod, M. A series of holes mlin bar M 'permits the vertical adjust ment of the lever arms m to correspond to different positions of the sleeves m on red M- 7 The cam e is adjusted. to actuate the acid ,/r,olls to approach the can. just after the crin1p ing action of the crimping disk has begun, and they are withdrawn at the same time as the crimping disks. The purpose of the chain M is to give )erfect flexibility to the connection between ar M and lever M, also to permit the acid rolls to be returned to their normal vertical position by the weight of bar M and lever arms or", slowly and without disturbing the contents of the acid cups.

The soldering devices S, Figs. 1 and 3, as has been indicated, are two in number, comprising practically independent, yet conjointly operated soldering tools and sets of soldering wire feed rolls. As these parts are the same in both devices, it is not necessary that I describe the structure 01 more than one e. g. the. one shown on the riglit in Figs. 1 and The soldering tool comprises a combustion chamber or fire box S attached to the end of a slidin bar S lying in a slideway formed by plates S and adapted to be actuated inwardly toward the carrier by a lever arm S, Fig. 1, mounted on rock shaft A already described, and outwardly by a spring S". Lever arm S is not )ivoted directly to bar S but to sleeve S, *igs. 12, 13 and 14, fitted on the end thereof. This sleeve is secured to the bar'by means of bolt S, the

outer end of which projects through the end of the sleeve and has mounted upon it a hand wheel S while the, other end is externally screw-threaded to fit the internally screwthreaded bore 8 in the end of the bar. A helical spring 8 lying between the sleeve and an ofiset s on the bolt makes the connection a yielding one. By rotating the hand-wheel, the reciprocating apparatus is shortened or lengthened as desired in order to properly position the soldering tool for different diameters of cans. As was stated in connection with the description of the vertical shaft 1) the rock-shaft A also serves to reciprocate this shaft and the carrier-frame thereto attached. An important functionof the helical spring (1", which forms an element of the step in which such shaft D is mounted, appears in connection with this double operation performed by rock-shaft A; for by means of such spring the can beneath the gripping disk corresponding to this particular soldering device, is raised sufficiently in ad vance of the forward movement of such soldering device to avoid the displacement of the can thereby. I am thus enabled to dispense with the extra cam, slide bar, and levers, or similar mechanism, that would be required to give a slightly retarded motion to the soldering device. l 7 The fire-box S is preferably composed of two readily separable portions, 5* s, forming a hollow box of substantially the shape shown'in the figures last referred to above. Removably secured between these two por- 5 tions is the soldering iron s which projects in front of the box and has a concave'outer, edge, the curvature of the edge in any par ticular iron being designed to fit the convex I curvature of the can with which the tool is 89 to be used. By having the members 8 s readily separable, one soldering iron is easily changed for another upon changing from one size of can to another. A pipe, 8 fitted into the bore s in the rear of the fire 5 box admits a properly proportioned mixture of gas and air which is ignited within the box, the productsof the combustion escaping in front by openings 8'' above and below I the soldering iron, which is thus easily main- 90 tained at the necessary temperature.

To provide an adjustable means of secur ing thefire box S to the reciprocating bar, the end of the latter is pro'videdwith 'a' downwardly projecting face- 8 provided with a vertical recessed slot 8 in which slides a block 8 adapted-to be positioned therein by means of ahand wheel 8. "A threaded bolt 8 passes through such block and a transverse slot in the back ,of the fire box S and screws into a cylindrical plug 8. fitted into the bottom of bore 8 in such fire box. The fire box is thus in eflect pivotedon the plug 8 being held laterally in any desired position on its pivotal axis by means. 05 of set screws. 8 3 while by means of hand wheel a any vertical position necessary to bring the soldering iron s exactly into proper position on the can is attainable.

Two sets of solder feeding devicesili, R, corresponding to the two solderingstations, are provided, Figs. 1 and 3, whereby solder wire 7 is fed to the soldering ironswhenthe latter are in contact witlr, the cans. The

' reels from which the wire is unwound are not indicated; theymay be secured in brackets or hangers about the machine where most convenient. From such reels the wire-is led between grooved rolls 1" 11' mounted in a bracket it on cross bar B Figs. 1.5, 16 and 1'7, and thence downwardly into close prox imity to the outer curved edge of the soldering iron by the adjustable guiding tube W.

A helical spring r positionedas shown is adapted to compress the wire bctweenflthe rolls suliiciently to cause it to be readily fed forward without slipping even though itxbe H of varying diameter as is frequently theea'se.

Rotation of the rolls is effected b'y'n cans of a horizontal shaft it, mounted alongside cross bar B on which one of the rolls, 1, is

mounted, and a vertical shaft R mounted in the end standard A and. connected with 'wheel. A spring 1 tends to hold such pawl 1-" in engagement with the ratchet wheel, the point at which the engagement takes place and the consequent amount. of rotation imparted to the ratchet wheel being a matter of regulation. by means of the throwotl' r. This thrmv-o'll' is adapted to he held in diiferent positions by means of a series of holes r in the top of bracket a, and a pin 1"" in. such throw-oil designed to engage the holes. Thus by means of this ratchet device and shafts, it it, the rolls may be rotated to feed the exact amount of solder wire rcqnircd to solder the end of the particular can. in process of manufacture, and this, 'moreover, coincidently with the contact of the heated soldering iron with the can.

Having thus described. in detail the various mechanisms entering into my machine and the separate processes performed by each, it only remains to point out how these 'n'ocesses are correlated in the operation of the machine as a whole. An operative assembles the parts of the cans, viz. the cylindrical portion and the two end portions, as shown in Fig. 5 and places such. assembled can on one of the disks on the carrier frame in the front of the machine, Fig. 1. The intermittent rotation. of such carrier hears the cans to the crimping and fluxing station and in succession. thereafter to the first and second soldering stations. Intcrmediately of the two soldering stations, which are on the rear side of the machine as viewed in Fig. 1, another 0 erative inverts the cans pre )aratory to tleir passing the second soldering station, for the reason already explained. During the periods of cessation from'rotation of the carrier frame, the lighter bar E is actuated to raise it so that the three cans occupy ing the three stations referred to are pressed against the upper rotating disks d. While thus held, the crimping disks, the flux rolls,- and the two soldering irons are simultaneously advanced, the solder wire feeding rolls providing in connection with the latter the requisite amount of solder. As the completed cans again pass forward to the front of the machine, a tirowotf of any approved design shown simply as a projecting arm, T, Figs. 1 and 2, discharges the cans into a conveyor or receptacle as desired. The operation of the machine is thus seen to be quite simple, but more noteworthy is the high degree of adjustability realized in its various parts. Thus to change the machine for operation upon a different size of can it is merely necessary to mount the proper size of disks on the various disk carrying spindles, fit the corresponding soldering irons in the soldering devices, adjust vertically the crimping disks and acid rolls and regulate by means of the convenient hand wheels the extent of the reciprocating movement of such soldering and crimping devices.
