SPECIFICATION forming part of Letters Patent No. 701,260, dated May 27, 1902.

Application filed June '7, 1901.

To all whom it may concern:

Be it known that I, FRED G. DIOKERSON, a citizen ofthe-United States, residing at Ohicago, in the countyvofOook and State of lilinois, have invented certain new and useful Improvements in Tipping-Machines, of which the following is a full, clear, and exact specification.

This invention relates to that class of cantipping machines designed for closing by solder the small vent in the cap or top of the can or other vessel as the cans file past the os cillating or swinging soldering-iron thereof, which is actuated to sweep across the top of each can as it passes and deposit a drop of solder over the vent; and the invention has for its primary object to cause each can to release the mechanism for imparting the necessary motion or action to the soldering-iron and to thereafter actuate or-drive such mech-. anism by power other than the can, whereby the distances between cans is rendered immaterial, as is also the position of the can upon the traveling conveyor, the mere weight of the can, wherever it be placed, being suffi cient to render the soldering mechanism active and such action being caused by agencies in no wise dependent upon the resistance of the can.

Another object of the invention is to provide improved means for causing the point of the soldering-iron to follow along the top of the can and conform thereto for a sufficient distance to effect the soldering operation and then rise above the levelof the can and return to its initial or starting position.

A further object of the invention is to provide improved means for automatically feeding the solder to the iron as required.

With these ends in View my invention consists in certain features of novelty in the construction, combination, and arrangement of parts ,by which the said objects and certain other objects hereinafter appearing are attained, all as fully described with reference to the accompanying drawings, and more particularly pointed out in the claims.

In the said drawings, Figure 1 is a plan view of my improved tipping-machine. Fig. 2 is a side elevation thereof, the supporting-frame for the conveyor being shown in transverse semi No. 63,498. (No model-i section on the line 2 2, Fig. 3. Fig. 3 is a front view thereof. Fig. 4 is a detail front view of a part of the mechanism for controlling the iron, showing the parts in the position they assume just beforethe iron starts to return to its initial position, the iron proper being shown in dotted lines. Fig. 5 isa. detail plan section of the solder-feeding mechanism. Fig. 6 is a transverse section thereof, taken on the line 6 .6, Fig. 5. Fig. 7 is a detail plan section of the trigger and lock mechanism by which the cans release the mechanism for actuating the soldering-iron and positioning the can with reference thereto, the can being shown in dotted lines in the act of engaging the trigger; and Fig. 8 is a similar view showing the trigger released by the can.

1 is the soldering-iron proper, is hollow, as usual, and provided with openings 2, Whereby it may be supplied with gas or other fuel through a pipe or tube 3, connected to the iron 1 by elbow 4., thus constituting a Bunsen burner for heating the iron and at the same time holding it in a depending position in readiness to swing into contact with the cans as they pass thereunder, as will be hereinafter described, the tube 3 being supplied from a distant source of fuel by flexible hose connection or other suitable means, as usual.

The tube 3 constitutes the supporting-arm for the iron, and it is held by a pair of clips 5, passing through slotted ears 6 and having thumb-screws 7 whereby the height of the ironiwith reference to the ears 6 maybe varied to suitthe requirements. The ears 6 constitute a part of a swinging frame having a web or member 7, which connects the ears together and carries a pair of perfo rated bosses S, in which is supported a shaft or pivot-pin 9,that constitutes a pivotal support for said frame upon a counterbalanced frame having two arms 10, in the ends of which the shaft or pin Sis journaled, and which arms are pivoted upon a bar 11, connected together by a member 12, uponwhich is formed or otherwise secured a counterweight 13, the bar 11 being mounted in standards 14, formed on main frame members 15 16. Thus it will be seen that the soldering-iron frame just described, pivotally sup ported on the rod or shaft 9, will be counterbalanced by weight 13 and permitted to rock on the shaft or rod 11 as may be necessary -to conform to the height of the cans.

One of the bosses 8 is carried downwardly in the form of an arm 17, as better shown in Fig. 2, and to one side of this arm is secured the upper end of a U-shaped spring 18, Whose lower end is secured to a crank-pin 19, carried by acrank or disk 20, which is mounted upon shaft 21, journaled in a bearing 22, formed on the main frame 23. This crankdisk is provided with a peripheral groove 24, as shown in Fig. 2, so as to better adapt the disk for winding a band or cable 25, which is permanently attached by screwclamp 26 to the disk and passes downwardly around an idler 27, journaled on stud-shaft 28, suitably secured to main frame member 29, and from the under side of idler 27 the band or cable passes around a horizontal drum or pulley 30, mounted on shaft 31, projecting upwardly from base 32 of the main frame, the cable being also rigidly secured to pulley or drum by screw-clamp 33, and from the drum 30 the cable passes under a second idler 34, mounted on stud-shaft 35, suitably secured to an arm 36 of the main frame, and thence passes upwardly over crank-disk 20. The purpose of this system of pulleys or idlers is merely to impart the motion of the horizontal drum or pulley 30 to the upright crank-disk 20, so that when the drum or pulley 30 is given a partial turn the crank-pin 19 will rock the soldering-iron frame 6 7 17 upon its pivotal support 9 and at the same time pull the frame downwardly bodily by teetering the counterbalanced frame 10 12 upon its pivotal support 11, it being observed from Fig. 3 that as the crank-pin 19 moves toward the right from the position illustrated in said figure it must pull downwardly as well as laterally upon the soldering-iron frame, and since the point of the soldering-iron is arranged permanently in a line passing through the centers of the pivot 9 and crank-pin 19 such point will be capable of moving up and down or lengthwise of said line as the counterbalanced frame 10 12 oscillates upon its pivot 11. Consequently it will be seen that should a can be placed below the point of the soldering-iron as this oscillatory motion begins the point would be pulled downwardlyinto contact with the can, and if the can be at the same time moved in unison with the iron the iron may be caused to remain in contact with the can a sufficient length of time to solder the vent while the can is moving past. To this end, therefore, the apparatus is provided with a traveling conveyer comprising a number of slats- 37 or other suitable supports for the cans, (shown at 38 in dotted lines,) and which slats are secured at their mid-lengths to a sprocket-chain 39, which derives motion from any suitable source and passes over and drives a sprocket-wheel 40, the ends of the slats being supported by guideways 41, and the conveyer thus constituted by the slats and chain being continuous, as usual in machines of this character. The sprocket-wheel 40 is mounted loosely upon the shaft 42, but is provided with permanent frictional connection therewith, so that when the shaft is not restrained by a superior force it will be revolved by the sprocket-wheel. This frictional action may consist of any of the wellknown devices for such purpose. The form of such device shown in the drawings consists of a pair of clamping-jaws 43 44, partially embracing a hub 45, fixed to the shaft 42, and being clamped with proper tension upon said hub by means of bolts 46. The

motion of the sprocket is imparted to the.

clamping-jaws by laterally-projecting lugs 47, formed on two of the spokes of the sprocket. On one end of the shaft 42 is secured a bevelgear 48, which meshes with a companion gear 49, journaled on the lower end of a vertical shaft 50, which is mounted in base 32 of the main frame and has secured to its upper end a turnstile 51, having the form of a star, as better shown in Figs. 7 and 8, whose points are a sufficient distance apart to admit between them a single can. If this turnstile 51 be not restrained, it will revolve continuously with the sprocket-wheel 40 and would engage the cans haphazard as they arrived on the conveyer-slats 37; but in order that the turnstile 51 may be held inactive until the can has arrived at the proper position with reference thereto and with reference to the soldering-iron and at the same time be in readiness to instantly advance the can in unison with the movement'of the iron with out depending upon the motion of the can induced by the conveyer, the turnstile is looked after each can passes through and it is unlocked as each can approaches it. This is accomplished by means of a pivoted dog 52, pivotally secured by pivot 53 to an intermediate point on a trigger 54, whose free end is curved partially across the conveyer 37 39 into the path of so as to be struck by the cans, as shown in Figs. 1, 7, and 8. The other end of the trigger 54 is connected to any suitable spring-actuated mechanism which will effect the release of the dog 52 from the points of the turnstile 51, which engage therewith when the trigger is thus deflected by the can. In the example of the invention shown in the drawings this is accomplished by pivoting the inner end of the trigger 54 to'one corner of a bell-crank 55, which is pivotally secured by a pivot 56 to a bracket 62, projecting overone of the guide-rails 57 58, which guide the can as it passes the soldering mechanism. The other corner of bell-crank is secured to one end of a delicate spring 59,

whose other end is attached to one end of an arm 60, and the other end of this arm is secured to the back of dog 52, which latter has a stationary pivot 61, securing it to some suitable support, the support shownin the drawings consisting of the bracket 62, which is socured to base By this means it will be TIC seen thatwhen trigger 54 is deflected inwardly by the can the effect will be to oscillate its opposite end outwardly on its fulcrum 53, stretching spring 59 and causing bell-crank 55 to pull lengthwise on the. trigger, which will be thereby induced to back away from that point of the turnstile in engagement therewith and permit such point to pass. As soon as the can passes the end of the trigger the spring 59 returns bell-crank 55 to its former position and at the same time forces dog 52 back again into a position across the circle described by the points of the turnstile, the returning movement of trigger 54 being limited by stop-pin 63, secured to dog 52 and adapted to come against one edge of trigger 54:. This construction of locking mechanism is resorted to merely for the sake of providing what might be termed a hair-trigger of sufficient durability to withstand the shock induced by the points of the turnstile striking thereagainst and at the same time be sufficiently'delicate to enable the cans resting upon the conveyer and having no connection with the latter other thanthat afforded by the mere weight of the can thereon to release the trigger with the requisite degree of certainty.

The trigger 54;, like the sides of the turnstile, between its points iscurved so as to ap proximately conform to the can and permit the can to come fairly within the embrace of turnstile-points before the turnstile is released, and in order that this relation of the can and the turnstile may be more effectually brought about and all variation in the position of the can with relation to the iron and the turnstile at the instant of the release of the latter may be prevented a curved spring 64 is provided on the opposite guidebar 58 in such a position as to detain the can after the trigger has been released until the point of the turnstile immediately behind it can come in contact with it and force it past the spring. By reference to Fig. 1 it will be seen that this spring 64:, as well as guide-bar 58, is made adjustable, so as to provide for cans of various diameters. As shown, the spring 64 is secured by a clip 65 to the bar 58, and the latter is provided with brackets 66, whose lower ends are secured by set-screws or bolts 67 to frame members 68, which have slots 69, through which said bolts pass, and these slots are substantially parallel and arranged at an oblique angle to the line of travel of the cans, so that when the bar 58 is carried outwardly for widening the path of the cans the spring 64 will also be'carried longitudinally of the line of movement of the cans, thus bringing its inner end to the point where it will engage the can after the latter comes up against the trigger 54, it being understood that should the spring 64: be fixed with relation to the line of movement of the can its time of contact against the can with relation to the time the can engages the trigger would gradually grow later as the distance between the guides 57 58 is increased. It is of course understood that the vent to be closed in the can by this machineis usually formed in the center of the cap or top of the can, and conseq'uently as the guide 58 is adjusted the iron would be adjusted accordingly by loosening the clips 5.

Motion is imparted to the pulley 30 for giving the iron the desired oscillation, as before described, from the turnstile 51 as each can passes through the turnstile, so that the iron in its movement will bear a definite relation to the movement of cans regardless of the position of the can on the conveyer or of the distances between the cans before they reach the turnstile. This motion of the pulley or drum 30is an oscillatory motion or partial rotation and is effected by the points of the turnstile engaging a wing 7 0, formed along one of the spokes of the pulley 30 on the under side thereof, and thus imparting to said pulley a partialturn as soon as the trigger 54: releases the dog 52 from the point of the turnstile in engagement with the latter, and the cable or belt 25 being positively secured to crank-disk 20a like oscillation or partial rotation will also be imparted to the latter, causing the crank-arm 19 to move from the position shown in Fig. 3 toward the right to about the position shown in Fig. 4, the point of the iron being thereby carried along with the can and yieldinglyin contact with the part to be soldered by the yielding action of the spring 18, which as the crank-pin moves downwardly is caused to pull the iron downwardly also if the weight of the iron and its pivotal frame be insufficient to accomplish that result. As soon as the can passes the turnstile and is free to be conducted away by the conveyer the iron swings back to its former position. (Shown in Fig. 1 and in dotted lines in Fig. 3.) This returningmovement of the iron is induced by a spring 31 on the shaft 31. The spring 18 is first expanded by the fore part and downward movement of the crank-pin 19 as the latter moves toward the right; but during the latter half of such movement the spring is compressed, as shown in Fig. 4, and consequently as soon as the wing 70') on pulley 30 is released by thepoint of the turnstile the tendency of spring 31 to recoil will throw crank-pin 19 toward the left and return it to its former position, (shown at Fig. 3,) at the same time returning the pulley 30 to its former position through the intermediary of the cable or belt 25, the dog 52 being always in readiness to arrest the rotation of the turnstile as soon as the can passes trigger 54B, and the cans are prevented from crowding against said trigger out of their regular turn by the points of the turnstile, which by embracing the cans in the described manner engage between them and hold the can immediately following that one which is in engagement with the trigger from crowding against the trigger before its regular turn or crowding the forward can against the trigger too rapidly, so as to get it out of time with the movement of the iron.

As the iron swings back to its initial or starting position it takes a higher path, so as to avoid striking the can which it has just soldered or striking the next approaching can. As the crank-pin moves upwardly at the final end of the soldering stroke toward the right it tends to lift the pivoted soldering-iron frame 6 7 17 on the pivotal point 11, and as it does so alaterally-projecting lug 71, formed on a depending arm 72 of the frame member 17, engages with a shoulder 73, formed on a sling 74:, which is pivoted at 7 5 concentrically with shaft 9 in its elevated position between two arms 75 76, formed on a projection 77 of the arm 16. To one side of the shoulder 73 in the sling 74 is formed a notch 78, into which the lug 71 descends during the fore part of the movement-of crank-pin 19 toward the right, so that the iron may be free to descend the requisite distances for contact with the can, and as it moves toward the right it causes sling 74 to move with it, and as crank-pin 19 approaches the end of its movement, lifting upwardly on the spring, it gradually raises lug 71 out of the notch 78 until the sling gravitates toward a perpendicular position, and in doing so carries its shoulder 73 under lug 71. At this period the movement of pin 19 toward the right is completed, the point of the turnstile having released wing on pulley 30, and spring 31 immediately forces crank-pin 19 back to its former position, as shown in Fig. 3; but in making the return movement lug 71 remains in contact with shoulder 73, and hence supports the iron at a greater elevation during its return movement and prevents it from accidentally engaging the cans. By the time the iron arrives at its initial or starting position again the sling 7 4 gravitates to the perpendicular and the lug 71 will be over the notch 78 and free to descend as far as may be necessary for permitting the iron to contact with the can when the next soldering motion begins.

In order that the soldering-iron may not through any accident or false movement be caused to descend prematurely into the path of the can, the lower end of the projection 72 is provided with a stop 79, which is so arranged as to be immediately above crank-pin 19 when the latter is at its normal or starting position, as shown in Fig. 3; but inasmuch as the crank-pin moves downwardly as the stop 79 moves horizontally with the iron the stop cannot interfere with the adaptation of the iron to the level of the can after the soldering movement begins.

80 is a tube or canal through which the sol der is automatically fed to the iron, the point or end of the tube being located contiguous to the pointof the iron when the latter is in its normal or starting position, as shown in Figs. 2 and 3. The solder is in the form of a corrugated bar 81, this form of solder being preferred in order that the corrugations may be utilized not only for carrying the requisite quantity of flux within each drop of solder in a well-known manner, but for enabling a feed-dog 82 to engage and feed the bar a drop or corrugation at a time to the iron. This feed-dog 82 is in the form of a spring, whose end projects through a slot 83 in the side of a tube 80 when the dog is pushed in one direction, and thus feeds the solder forward, the solder being prevented from returning as dog 82 moves backwardly by a holding-dog 84:, projecting through a slot 85 in a bracket 89, through which the solder passes, and which also constitutes the support for dog 84. The dog 82 is given a reciprocating motion for thus feeding the bar of solder by the rotation of the t'urnstile 51, whose points are adapted to engage a crank-arm 86, secured to the lower end of a vertical shaft 87, which is journaled at one end in a suitable bearing 88 on the main frame and at its other end in the bracket 88 secured by bolts 90 to frame member 16. (See Fig. 2.) The upper end of shaft 87 is provided with a crankarm 91, carrying a pin 92, engaging in a socket 93 in the lower end of a lug 94:, which is secured to tube 80 by set-screw 95, so that as the shaft 87 is oscillated the tube 8O will be reciprocated, and dog 82 being secured to tube 80 by lug 96, as shown in Fig. 5,-it will be given the necessary reciprocating movement for feeding the solder to the iron. Tube 80 is guided by bracket 89 and an arm 98, and the solder passes through and is supported and guided by an arm 96 on the frame.

In order that the feeding movement may be regulated, a set-screw 97 is provided and so arranged as to strike set-screw in the lug 94 when it makes its return movement for causing dog 82 to again engage the solder. This set-screw 97 is threaded in the arm 98, constitutinga part of the bracket 89 and bearing 88, as better shown in Fig. 2. This return movement of dog 82 is induced by a'spring 99, coiled on the upper end of shaft 87 and having one end secured thereto and the other end affixed to the bearing 88, so that when the crank-arm 86 is released by the point of the turnstile the feeding-dog 82 will be immediately returned into position for advancing the solder prior to the forward or soldering movement of the iron, it'being understood that the points of the tnrnstile engage crankarm 86 in advance of engaging wing 70 on pulley 30.

100 isa friction blade arranged to be brushed by the points of turnstile 51 before the latter engage the dog 52, so as to lessen the shock and perform the more important function of preventing retrograde movement of the turnstile, said blade 100 consisting of a flat spring secured to part 23 of the main frame.

102 represents two parallel shields or screens (shown in full lines in Fig. 1 and in dotted lines in Fig. 3) secured at a short distance apart to frame member 75 for the purromeo pose of shieldingthe mechanism from the heat of the iron.

It will of course be understood that the invention is equally applicable for tipping any receptacle or object other than a can, which is a term used herein for the sake of convenience and brevity, meaning any object to be tipped, and with the tipping implement or soldering-iron maybe employed any suitable form of sealing substance other than solder.

Having thus described my invention, what I claim as new therein, and desire to secure by Letters Patent, is
