CAN-MAKING MAcHmE.

SPECIFICATION forming part'of Letters Patent No. 741,620, dated October 20', 1903. Y Application-filed November 20, 1902'. erial No. 132,128. (No model.)

To a/ZZ whom it may concern: i

Be it known that L'WILLIAM D. BEooKs, a citizen of the United States, residing at Baltimore, Maryland, have invented certain-new andt useful Improvements in Can gMaking" for the can-bodies and to means for locking and soldering the side seam of the saidbodi es.

The inventionis 4illustrated in the accompanying drawings, in'whichl.

Figure 1 is a vertical sectional View from front to rear of the machine with parts in side elevation. Fig. 2 is a view on the line 2 2 of Fig. 1 looking toward the left-hand side of said gure. Fig. 3 is a side view of the horn and bracket. Figs. 4 and 5 are side and end views of the register or gage bar. Fig. 6 shows a side and end view of another gagebar. Fig. 7 is a side view of azpresser-foot. Fig. 7 is a plan view of Fig. 7. Figs. 8 and 9 are side andv plan views of the folding-` wings. Fig. 10 is a view of a lever. Fig. 11 is a View of a iiuX-tank. Fig. 12 is a detail view of a guide-Wheel for the can. Fig. 13 is a Aview of the inner soldering-iron. Figs. 14 and 15 are detail views of a linx-bath.

for receiving the can-bodies from the horn.

Fig. 18 is a sectional view on line 18 18 of Fig. 1..

Fig. 19 is a side view of one of the breakingknives. Figs. Y2O and 21 are detail views of the fixed breaking-knives.

The sheet-metal blank from which the canbody is to be formed is placed by the operator upon the table 1 and just in rear of a detent or detects 2, pivoted to the said 'table and projecting slightlyl above the same. From this position the sheet-metal blank is moved toward the rear by carrier means consisting of sliding plates'or blocks 3, secured by screws 4 to dovetailed slide-bars 5, which move in guideways 6 in opposite sides of a bracket 7, secured to the face or theupright frame 8 of the machine, which frame also supports the table 1, as shown in Fig. '1. The plates 3 each carry a series of pawls 9,

pivoted thereto, to feed the blank step by step rearwardly as said plates are reciprocated through the connections consisting of the links 1'0, a lever 11 carried by a rock-shaft 12 journaled in a bracket 13, the said shaft havingan arm 111 provided with a projection or roller 15 entering a cam-groove in the face of the disk 16 on a shaft 17 journaled in bearings at the top of the frame, said shaft being rotated through beveled gearing 18 from a vertical shaft 19, which is driven through beveled gearing 2O from a main driving-shaft 21, which has the pulleys 22 thereon. The rst rearward movement of the carrier means carries the blank beneath 'the bracket 7 to mechanism designed to break ithe edges of the blank, so that they may be interlocked for forming the side seams. In this position the blank is held by two of the detents 2'. The breaking means consist of presser-feet 23 23', pivotally supported one on each side of the bracket 7. The presserfoot 23 is journaled iu a bracket 24, and it is adapted to hold the blank by downward pressure upon the upper surface of a ixed breaking-knife 25, secured to a suitable bracket 26, suitably supported on the frame. The presser-foot 23' for the opposite edge of the blank is pivoted to a bracket 23X and is adapted to press upwardly against a breaking-knife 25', secured to a suitable bracket 26', secured 'to' the'machine.

With these fixed breakingknives movable breaking-knives cooperate, one of these (marked 27) being carried by a lever or arm 28, pivoted on the same pin 23X y with the presser-foot 23. This breakingknife moves downwardly in the breaking operation, while for the other edge of the blank the breaking knife 27 moves upwardlyf',

Each of these breaking-knives is of curved f;

form and when operated they bend the edge of the blank which projects over the adjacent Xed breaking-knife 25 or 25', the one on the right of Fig. 2 bending the edge downwardly, while that on the left of Fig. 2 bends the edge upwardly. Between the levers 28 or 28', carrying the movable breaking-knives,and the presser-feet springs 29 are interposed, so that as soon as the breaking-knives begin to move the springs will be compressed and i the l presser-feet will be forced with a yielding pressure against the sheet-metal blank to hold it while the breaking operation is being performed. In order to provide means for gaging the position of the blanks in relation to the breaking-knives, I provide bars 30, pivoted to the arms 28 28 and slotted at 3l to receive pins for guiding the arms in their movement. There is a pair of these arms for each breaking device, and the arms of each pair are connected by a cross-bar 32X, which lies with its face at a slight distance from the edge of the fixed breaking-knife, so that the projecting edge of the blank will'bear thereagainst to be properly positioned. It will be noticed that these gage-bars move away from in front ot' the fixed knives as soon as the movable knives begin the breaking operation, so that said operation will not be interfered with. After this breaking operation has been performed the carrier means, through one of the pawls thereonthe intermediate oue in this instance-will cause the blank to be moved rearwardly one step, where it will be retained by one of the detents on the table l, and while in this position iiux will be applied under the broken or upturned edge of the blank, so that when the broken edges are interlocked and hammered down, as will be hereinafterdescribed, the flux will lie well Within the joint, s0 that the solder will-f1nd its way to the innermost parts of the said joint. This flux-applying device consists of a bath 32, suitably supported, and a brush 33, operated through suitable mechanism to dip into the bath and apply the flux under the npturned edge as the blank passes bythe brush. After this fluxing of the edges has taken place the carrier means move the blank another step rearwardly, this action being due to the last of the series of carrier-pawls acting on the blank. The blank now lies beneath a former 3ft of cylindrical form, which projects rearwardly through an opening 35 in the main frame and forms a cylindrical prolongation to the rear of the said bracket 7. At this point the flat blank is bent up into cylindrical form, so that its broken edges will interlock. When the blank has arrived under the cylindrical horn or former, a block or plunger 35 rises and grips the blank against the under side of the horn or plunger. This plunger is carried by a stem 36, operated by an arm 37 on a rockshaft 38, journaled in bearings 39, secured to the frame, the said rock-shaft being operated by an arm 40, having a roller 4l entering a cam-groove in the disk 42 on the shaft 21, before described. Immediately after the blank is gripped by this block or plunger 35 a carriage 43 is moved upwardly in its guides 44, secured to the frame, so as to bring a pair of wings 45, pivoted to the said carriage, into position to fold the blank around the cylindrical former, the said vertical movement of ihe carriage being effected from a cam 46 on the shaft 2l, which has a groove receiving a roller on the lower part 43 of the carriage,

the upper and lower parts of the carriage being connected adjustably, as shown in Fig. l, by the screw-threaded bolt 47 and nuts 48. These wings are operated by links 49, connected with levers 50, fixed on rock-shafts 5l, suitablyjournaled in the frame, the said rocksha'fts being operated from cams 52 on the shaft 2l through blocks 53, arranged to slide in ways 5I on the frame, said blocks having rollers entering the groove in the face of the cam 52 and being connected by links 56 and arms 57 with the rock-shafts 5l. Through this mechanism the wings are folded up around the horn or former and the ends of the blank interlock with each other. One wing may move slight-ly in advance of the other, as in ordinary practice. The horn or former is provided with a spring portion 57', so that the end of the blank on that side will be held slightly away from the horn or former, with its bent flange extending inwardly, so that the other end of the blank maybe passed under the same to interlock therewith. I utilize the

connections

52, 53, 56, and 5l, just described ,for operating the breaking mechanism, and for this purpose the rock-shaft 5l has arms 58 connected by links 59 with the arms 28 28. By this mechanism While the folding operation is being done at the horn or former the breaking operation is being done at the breaking mechanism.

After the blank has been folded and its ends interlock'ed I register the interlocked edges directly over the groove 60 in the top of the horn for the hammering operation, and for this purpose I provide a registering-bar or gage 6l, carried by a slide (52, moving in a bracket 63, secured to the upright frame or plate of the machine, the said slide being operated through a lever-and-link connection lkfrom a slide 65, moving in guideways 66, secured to the face of the said vertical plate or frame, the said block having a roller 66' connected therewith entering a cam-groove in the face of a disk 67 on the shaft 17, before described. The register-bar or gage is normally retracted away from the groove in the former while the folding is being done, and it is advanced after the edges are interlocked, so as to accurately register the interlocked edges with the groove and against the end of the spring 57.

In order that the gage or register bar may advance while the wings are still in their folded position, I cut away the wings at the points 67, Figs. 8 and 9,'s0 that the fingers or projecting portions 69 of the register-bar may pass .through these recesses and get in registering position. Vhile the interlocked edges are thus held properly registered, a hammer 69 descends and presses the interlocked edges together to make the seam. This hammer is carried by a block or carriage 70, sliding vertically in ways 7l on the vertical plate or standard of the machine, the said sliding block or carriage being operated through an adjustable link 72 from a crank 73 of the IOO IIO

shaft 17. The cylindricalbody is now moved from oft the horn or former' by a pawl or A burner-tube 79 extends from the rear end of the horn into this cage, so as to heat the can-'body blank. This tube is supplied with gas from a pipe 80, connected with a passage 81, extending vertically from the bracket 7 and thence horizontally to the rear end of the horn. On this burner-tube and within the cage I support a soldering-iron 82 by means of arms 83, said iron consisting of a plate having a groove 84 extending therein longitudinally and centrally. As the can-body passes through the cage liux is applied to the seam by a brush 84', carried by an arm 85, having a roller 86 moving over a camWay 87 on the receptacle 88, containing the bath of iiux. The arm 85 is reciprocated by a lever 86',

' pivoted at 87' and connected by a link 88 With a lever 89, which is operated by a roller 90 thereon entering a cam-groove in a disk 91 on the shaft 17. After 'passing the iiuxbrush the can-body passes beneath a soldering-iron 92, supported by an arm 93 on the standard 94, the said soldering-iron having an opening 95 extending therethrough for the passage of the solder-wire, which is fed from the reel 96, supported on the standard 94, through feed-rolls 97 98, the former of which is provided With a ratchet-wheel 99, operated by a pawl 100, carried by a lever 101, operated by a link'102 from the lever 1l, before described.

The groove in the internal soldering-iron is tinned, and as the can-body passes over this iron it -is heated, so that it is in proper condition to receive the solder fed through the outer soldering-iron at 95.

The groove in the inner soldering-iron receives the seam and guides the same, the said seam thus remaining uppermost and'being properly directed to the outer iron to receiveV the solder. l

` Below the internal iron a trough 106 is supported on the burner-tube to catch any particles of solder or tin which may drop, the said internal iron having openings in the bottom of its groove, as at 84X.

1 The outer soldering-iron may be hea-ted by a jet 107.

It will be noticed from the above that the main frame of the machine comprises an upright plate or standard, with the horn lprojecting on one side thereon and the bracket 7 on the other side, together with thebreaking mechanism. It Will be noticed also that various connections are'inade to the operating elements from two cam-shafts, one`at the top and the other at the' bottom ofthe ma-A chine, and these various connect-ions are supported on the main frame.

The`iux-bath`32 is supported, as shown in Fig. 14, by a suitable bracket 9 6 from the bracket 7. The flux-brush 33is carried. by an arm 97', pivoted to a lever 98', which is pivoted to a bracket 100', operated from thel lever 89 through a rod 99. This mechanism is representative of any which may be found suitable for the purpose. v

The arm 97l has a roller 101', which Works over a cam projection or track 102l on the tank of the bath to raise and lower the brush into and away from the tank as the arm 97 is reciprocated. This mechanism acts in uni` son with and in a similar manner to that described in connection with the linx-brush 84.

On the rear side ofthe tank 32 a cam or incline 32 is placed. The stem 33 of the brush is jointed at 33X, and-below the joint it isv provided with a roller 33", which as the brush descends engagesl the incline and causes the lower end of the brush-stem to be turned laterally, so that the brush kwill enter beneath the upturned liange ofthe blank.

In Fig. 14 the parts are in the position assumed byv them When the brush 33 is Within the tank, and it consequently appears in dotted lines in said iigure. The position of the brush when applying the flux under the broken edge of the blank is also indicated in this figure, this latter position being the lowermost one that the brush assumes.

After leaving the horn Ythe can-body is engaged by a guide wheel yor roller 103, having a flange or edge 104 to enter the crease'at the seam, and'thus guide the can-body,'so that its side seam will be held uppermost. guide-wheel is arranged at the front end of This IOO

the cage, being supported in a bracket 105.

Before leaving the guide rim or ange of this wheel the seam of the can engages the groove -in the internal iron', to be guided thereby.

Each linx-tank may be provided with a reservoirBS, Fig. 11, adapted to feed the liux automatically, for which purpose it is connected with the tank at 88 and has an airpipe 88" reaching down to the level it is intended to maint-ain the flux. Y

Itv will be noticed that the pivots of the breaking-knives are arranged back from the edge of the fixed knives, so that as the curved knives swing on their pivots they will describe arcs passing close across the edges of the iixed knives, the concave sides of said arcs being toward the edges of the fixed knives.
