UNITED STATES PATENT OFFICE.

WILLIAM M. HOLLOWAY, OF CHICAGO, ILLINOIS.

SOLDERING-MACI-IINE.

To all whom it may concern:

Be it known that I, l/VILLIAM M. HoLLowar, a. citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Soldering-Machines; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in soldering machines and is shown more particularly as adapted for soldering bail ears or lugs on pail blanks.

In the construction of sheet metal or tin pails such as are used extensively for lard pails and for many other purposes, a bail ear or lug is soldered on opposite sides of the pail near the top to receive the bent wire bail of the pail. I-Ieretofore the securing of said lugs upon the pailor upon the blank has been a comparatively slow operation and necessarily more expensive than is desirable.

The object of this invention is to aiford an exceedingly cheap, simple and positively operating machine whereby the pail blanks of suitable size are fed flat into the machine, and the bail lugs secured in place by the use of heat applied from below or the opposite side of the blank, the blank at the point opposite the lug or ear being subjected to a cold blast after the lug is attached and before delivery from the machine.

It is also an object of the invention to afford means for adjusting the machine for blanks for different sizes of pails and also for different heights or sizes of bail lugs and to so construct the machine that the parts thereof in any manner subjected to heat, are open to the atmosphere to permit of rapid radiation.

The invent-ion embraces many novel features and consists in the matters hereinafter described and more fully pointed out and defined in the appended claims.

In the drawings: Figure 1 is an end elevation partly broken of a machine embodying my invention. Fig. 2 is a top plan View thereof. Fig. 3 is a central vertical section of the machine taken longitudinally of the shaft and showing the shaft in elevation. Fig. 4 is a section on line 4% of Fig. 2.

Specification of Letters Patent.

Application filed June 15, 1908.

Patented Nov. 23, 1909. Serial No. 438,461.

Fig. 5 is an enlarged fragmentary detail taken in section, and illustrating the construction of the heating plates and burner. Fig. 6 is a similar fragmentary view taken in elevation and showing the cold blast pipes. Fig. 7 is an enlarged fragmentary section of the cam and ring. Fig. 8 is a detailed face view of the driving gear for the Geneva gear.

As shown in the drawings: Said machine comprises a frame consisting of end members A, which may be of cast metal or constructed of any suitable material, and are rigidly connected on opposite sides longitudinally thereof by side bars aa, which serve to stiffen the frame and afford a table upon which at each end are bolted uprights a a a upon which the main shaft B, is journaled. As shown, said frame members may also be constructed of cast metal of suitable shape to afford a support for the driving gears as Well as said shaft, as shown in Fig. 1, each of said end frame members o a*, on the driving end of the machine being extended rearwardly and approximately horizontally from the shaft B, for that purpose.

As shown, a shaft B, is journaled at the top of the frame members a a parallel with the shaft B, and secured in the outer end of the shaft is a driving pulley Z), adapted to be engaged by a belt driven from any source of power. Also secured on said shaft, is a pinion b, which meshes with a gear 6 on a shaft B parallel with and at the rear of the shaft B. Also secured on said shaft B is a pinion b which meshes with a gear 6*, rotative on the shaft B, and provided, as shown in Figs. 2 and 5, on its inner face with a pin 6 adapted to engage in the radial slots of a Geneva gear 6, secured on the main shaft B. Said Geneva gear, as shown, is provided with a number of radial slots corresponding with the number of intermittent movements of the shaft B, in each revolution thereof and integrally secured 011 said gear o is a segment 6 adapted to engage in the concave seats in the periphery of the Geneva gear between the slots to hold the shaft B, rigidly between the intervals of movement thereof.

Feathered on the shaft B, are carrying wheels CG, of equal size, and, as shown, provided on the periphery with a number of flat faces corresponding with the number of slots in the Geneva gear. In the present machine, ten of such flat faces are provided, which, as shown, are directed obliquely with the radius of the wheel passing through the center thereof, thus providing at the rear side of each of said flat faces, a radial, outwardly directed, ratchet-like shoulder 0. The rim or face of each wheel, as shown, is comparatively broad, and at the inner edge said rim is integrally connected with the web on which is secured an integral hub 0 adapted to be held from rotation on the shaft by means of a feather c and held from longitudinal movement in adjusted position on the shaft by means of a set screw 0 or any other suitable equivalent therefor.

Each of the flat rim faces of the wheel is cut, as shown in Figs. 1, 3 and 5, to afiord a comparatively large opening therethrough adapted to be covered by a relatively thin plate of sheet steel or other suitable metal 0, adapted to quickly radiate heat, and provided with a circular aperture therethrough.

Pivotally secured on each of the shoulders c, is a clamping arm D, which extends centrally over said plate 0 and is provided on its under side with a seat adapted to receive the ear or lug therein, as shown in dotted lines in Fig. 2, and as shown, a lever arm (Z, rigidly secured on said clamping arm at the end thereof depends from the pivot pin d, and is provided at its lower end with a roller (Z adapted to engage the actuating cams whereby said clamping jaws are actuated. As shown, said cams indicated by DD are adj ustably secured upon a ring (Z concentric with the shaft B. Said ring is held from rotation on the shaft by means of a bar (1*, bolted to the ring (Z and also adjustably secured at its lower end on a longitudinal bar (Z bolted. to the frame. The cams, as shown, are provided with parallel, longitudinal slots adapted to receive therein bolts (Z which rigidly engage the cam to the ring but which permit the same to be adjusted outwardly or inwardly by releasing the bolts. As shown, the cam D, projects forwardly from the shaft B, into position to be engaged by the rolls 6Z on the end of the clamping levers (Z, to throw the clamping jaw outwardly from clamping position and to hold the same outwardly while inserting the blank and the ear lugs in place. The cam D extends obliquely downwardly and rearwardly from the shaft in position for engagement by the rolls (P, on the clamping levers to throw the clamping jaw outwardly from clamping position to release the blank after the operation is completed. As shown also, the Web of each of said carrying wheels is provided in advance of each of the clamping levers with a lug (Z through which extends a push pin (Z which bears on the forward side of the clamping lever and a spring 0Z is provided on said push pin, which acts normally to hold said clamping jaw in clamping relation, as shown in Fig. 4. As shown, the two carrying wheels are identical in construction in. all respects and arranged with the webs on the inner sides thereof and are entirely open on the outer sides or ends of the machine.

Extending upwardly at the front of the machine is the fuel supply pipe E, which extends through a suitable adjustable clamp on the frame bar a, and extends into the open end of the carrying wheel C,'and curving upwardly over the shaft is provided, as shown, with three branch pipes e-e -e each provided with a suitable burner nozzle 6 inclosed in a somewhat conical tube 6 adapted to direct the frame through the aperture in the plate 0 when the carrying wheels are at rest, said branches being so arranged that the burners act upon three of the adjacent apertures in the carrying wheel at the same time whenever said wheel is at rest. As shown, the pipe E, is also provided with a laterally directed branch 6, which is connected by means of a hose pipe 6 with a pipe 6 which extends upwardly into the carrying wheel C, and is provided likewise with branch pipes c-e -c such as before described, the arrangement and construction of which, and the burners therefor are each as before described with reference to the carrying wheel C. Also extending upwardly at the end of the frame is a pipe F, connected with a suitable blower or source of air pressure, said pipe also extending through the adjustable clamp e, and thence upwardly and inwardly of the carrying wheel and be neath the shaft B, and provided, as shown in Fig. 6, with branches j, two in number, and positioned to direct a cold blast through two adjacent apertures in the plates 0, and next adjacent to those acted upon by the burners. In a similar manner a branch f extends from said pipe F, and is connected by means of a hose pipe F, with a corresponding pipe f which extends into the carrying wheel C, and is likewise provided with branches as before described, and for the same purpose. As shown also, the pipes f and a are secured on the frame bar a, by means of an adjustable clamp e.

Secured at the rear side of the frame is a' chute G, which inclines inwardly and down wardly to direct released blanks upon the lower inclined chute g, which is directed rearwardly and downwardly toward any The operation is as follows: The carrying wheels are adjusted on the shaft B, by loosening the set screws and sliding the same to a position corresponding with the length of the blank it is desired to operate upon, this, of course, depending upon the size of the pail to be made, said adjustment being such that the blanks when laid upon the flat faces of the carrying wheels shall be so positioned that the point at which it is desired to attach the lugs lies centrally over the apertures in the plate 0 Having so adjusted the carrying wheels, the same are rigidly engaged upon the shaft by means of the set screws 0 and if necessary, the cam rings (Z may be also adjusted by loosening the nuts in the lower end of the bar (P, and sliding the same to whatever extent may be necessary to insure said bars at all times clearing the clamping levers. Of course, the fuel and air pipes are likewise adjusted to insure that the delivery thereof is at the center of the ear lug attached to the blank. For this purpose, the clamps e-e may be adjusted longitudinally of the frame bar a, to exactly position said pipes as desired. The flexible hose sections 6 -f permit of any desired adjustment thereof. Having adjusted the machine, the blanks are fed into place beneath the clamping jaw at the station indicated by X, on Fig. l and Fig. L, at which point the clamping lever is elevated on the cam D, affording space to insert the blank and to drop the ear lug indicated by 00, in place, one near each end of the blank, as shown in Fig. 2. This is accomplished during the interval of rest of the carrying wheels. The continuous rotation of the gears, however, almost immediately brings the pin Z), into one of the notches in the Geneva gear, with the effect of rotating the carrying wheels another station and closing the clamping jaws upon the ear lug and blank partly under action of gravity owing to the weight of the clamping levers, but mainly, because of the action of the spring d", which forces said lever downwardly bringing the clamping aw firmly into clamping relation. The carrying wheels coming to rest at the next station position the blank and the ear lug directly in alinement with the first burner e, heating the blank beneath the ear lug, and (inasmuch as the ear lug before insertion into the machine had been coated on the under side its flange with solder) fusing the solder, and also the thin coating of tin on the blank. Inasmuch as the interval of rest is exceedingly brief, several of such burners are desirable, though the number, of course, will depend upon the rapidity of motion of the carrying wheels and the length of the period or interval of rest. In practice, it has been found that three of such burners permit of rapid movement of the wheel and very brief intervals of rest, in fact, the briefest possible interval consistent with the insertion of the blanks and the ear lugs into place manually. Having passed the last burner 0 at which the solder was completely fused, at the next interval of rest the hot spot on the blank is positioned directly opposite one of the cold blast branches f, rapidly cooling the same and also cooling the thin plate 0, upon which the blank rests. Such cooling operation may also be continued for one or more intervals, any desired number of such branches being connected in the cooling pipe. The cooling, however, having sufficiently progressed to solidify the solder, the depending end of the cam lever next engages the inclined face of the cam D throwing the clamping jaw outwardly, as shown in Fig. 4., and permitting the blank to fall upon the inclined chutes Gg and into the receptacle g.

Owing to the peculiar construction of the flat faces of the carrying wheels the width of the blank is quite immaterial, inasmuch as the edges of each blank indicated by Y, may project over the clamping jaw for the next preceding blank, in this manner enabling the machine to receive and to operate successfully upon blanks of any desired width.

Of course, I am aware that instead of ten clamping jaws on each carrying wheel the number of flat faces and corresponding clamping jaws may vary depending upon the size of the wheel, its rate of movement and whether the blanks and ear lugs be fed manually into position or automatically, which may, of course, be very easily accomplished. I am also aware that for any blank or article which may be more or less curved or present a non-fiat surface, the face of the wheel should desirably be shaped to lit thereto, and of course, the clamping jaws desirably shaped on the under face to con form somewhat to the article to be engaged upon the blank. Furthermore, the intermittent motion is not indispensable, inasmuch as a. slower rate of continuous rotation per mits of the feeding of the blanks or the lugs or articles to be attached thereto into position very readily, and when automatically feeding, continuous rotation may be preferable, with, of course, the consequent variation in the number of burners and cooling nozzles.

Obviously, many features of construction and operation may be varied and I therefore do not purpose limiting this application for patent otherwise than necessitated by the prior art.
