SEALING MACHINE.

Application filed, July 25,

Y '0 all whom it may concern:

Be it known that I, JULIUS A. SOHWANTES, a citizen of the United States, and resident of Milwaukee, in the county ofMil-. waukee and State of Wisconsin, have invented new and useful Improvements in Sea-ling Machines, of which the following is a description, reference being had to the accompanying drawings, which are apart of this specification. v I

This invention relates to improvements in sealing machines, more particularly adapted to applying labels or seals to small packages such as cakes of soap and the like.

It is one of the objects of the present in vention to provide a sealing machine which will apply seals to cakes of soap or the like after they have been wrapped.

A further object of'the invention is to provide a sealing machine which will moisten the glue on the seals or labels applied to the packages.

A' further object of the invention isto provide a sealing machine which will press and secure a label onto each package as it is fed into the machine. I

A further object of the invention is to provide a device of the class described which will automatically feed the seals, indivldually, into package applying position.

A further object of the invention is to provide a device of the class described having means thereon for automatically notifying the operator when the barrels containing the seals have become exhausted.

A further object of the invention is to provide. a device of the class described having means to permit the refilling of barrels when one is in feeding position. v

A further object of the invention is to provide a sealing machine which is of simple construction, is strong and durable, and is well adapted for the purpose described.

IVith the above and other objects in view, the invention consists of the improved sealing machine and its parts and combinationsas set forth in the claims and all equivalents thereof.

In the accompanying drawing, in whlch the same reference characters indicate the same parts in all of the views:

Referringto the drawings, it will be seen that the numeral 12' indicatesthe frame of a sealing machine. The power for actuating the movable parts in: the machine is trans mitted from a source of power (not shown) by means of a chain13 running over an idler pulley 14 revoluble on a shaft 15 to awheel 16 which is mounted'fast on a shaft17 Adjacent the wheel 16 is .a second wheel 18 which is revolved by means of said shaft 17, and by means of achain drive 19, a wheel 20, mounted fast on shaft 15, is rotated, said last mentioned shaft being also rotated thereby. The inner end portion of said shaft carries a revoluble member 21 .pro-

vided with an arm 22 which is engageable with a Geneva cam 23"mounted on a shaft 2 1 thereabove. A seal applying'member 25 is also mounted onshaft 24 and its hub portion 26 is bolted to said'Geneva cam so as to be operated thereby. v

Said sea'l'applying member 25 is shaped as shown in Figs. 4 and 5, and is provided with four-,spaced, radially extending cylindrical sleeves 27 which are movable between the outer casing 28 of member 25 and inner sleeves 29. Intermittent motion is transmitted tomember 25 by'said Geneva cam and when member 21 revolves in one direction the Geneva cam and seal applying member 25 will be rotated one-quarter of a revolution to every revolution of member 21. As shown in Figs. 1 and 2, the Geneva movement has just been completed and the seal applying member 25 is idle. In this position, one of the cylindricalsleeves 27 is juxtaposed theopening of a barrel 30 and at this point it is adapted to move into and then out of the mouth of the barrel as shown in Fig. 4. The mechanism for operating said sleeves will be explained hereinafter. Due to a suction applied at the end 31 of the shaft 24 by means of a pump (not shown) or other convenient means, in connection with a tube or hose 32, there being communicating openings between said sleeves, and the tubular shaft 24, one of the labels or seals 32 contained in the barrel will be sucked against the end portion of the sleeve and will be held thereagainst. The sleeve then moves .out of the barrel and the inoven'ients of the parts are timed so that at this instance member will again be moved 90. At this point, the lnucilage side of the label held by the sleeve will contact with a roller 33 which is kept wet by means which will hereinatfter be ex plained. Then, member 25 will again be moved 90 so that the sleevereferred to is adjacent the under side of a movable carrier 34 which is mounted above the frame 12 and receives wrapped bars of soap or other packages from a'wrapping machine (not shown) and moves the same slowly in the direction indicated by the arrow in Fig. 2. The suction which holds the seal to the cylinder sleeve, as was mentioned, is at this point released, and the seal or label is secured to a cake of soap or package on the carrier. Inthis connection, it should be noted that the tubular shaft 24 has an oscillating motion. This motion is derived from the shaft 17 by means of a cam 35 carried thereby. Shaft 24carries a crank 36 from which extends a series of pivotally connected together links 37, 38 and 39. The free end of link 39 hasth'ereon a roller 40 as shown in'Fig. 2, and saidfroller is adapted to ride in the eccentric groove 41 of cam 35. Thus, as said cam revolves, a timed oscillating motion will be transmitted by means of said links and crank :36. to thev tubular shaft24. The end portion 42 of shaft 24 is solid, butis provided with a longitudinally extending aperture 43, and a communicating port 44 which are adapted to register with ports 45. The parts are so arranged and timed that ports 44 and 45 will register when a sleeve is adjacent the carrier. Hence, when the ports register, air will be admitted through the exterior opening 46 of the aperture 43, destroying the suction and blowing the label from the end portion of the sleeve 27. The above described cycle repeats itself and, of course, each of the sleeves 27 is performing the same cycle.

To operate the sleeves 27, a cam 47 is freely mounted on shaft 24 adjacent member 25. A timed, oscillating motion is transmitted to said cam by a grooved cam 48 mounted on shaft 17 and revolved thereby. Said cam 48 has an eccentric groove 49 formed in its face in which a roller 50 Geneva cam 79. The are as shown in lilig.

rides. Said roller in turn is carried by the end of a link 51 which is pivotally connected with links 52 and 53, the last of which is connected with cam 47, as at 54, to oscillate it.

Said sleeves 27 are formed with ratchet portions 55 engageable with cog wheels 56 which are carried within the member 25 on shafts 57 extending transversely through the member 25, as shown. The outer ends of said shafts adjacent the cam 47 are pro vided with arms 58 and rollers 59 which are adapted to ride on said cam 47. Springs 60 are coiled about the opposite end portions of said shafts between the heads 61 and the surface of member 25, being secured as shown in F ig. 5. Thus, the action of said springs will tend to keep the rollers on the cam 47 at all times. Said cam 47 is so shaped and moved that the shafts 57 which are rotated by the rollers will rotate the cog wheels to raise and lower the sleeves 27 at the desired time. Thus, when a sleeve 27 reaches a barrel 30, the cog wheel 56 will be moved to first slide thesleeve into the barrel and then out of the barrel to normal position. The coiled springs 61within the inner sleeves 29 assist in returning the sleeves to normal position.

As was mentioned heretofore, when mem ber 25 moves so that oneof said sleeves is rotated a quarter of a revolution away, from a barrel, by the sleeve will be moistened. To accomplish this, a pan of water 62;is provided having a wheel 63 rotating therein. wheel is secured on the end of a shaft 64 the mucilage side of a label held l Said which is driven from shaft 17 by means of a chaln connection 66 between a gear 65 on a said shaft and a double gear 67 onsh aft 68.]

The other portion of the double gearfhas a chain connection 69 with a gear wheel 700s. said shaft 64. To transferwater from the wheel 63 to a label when a sleeve is in posi tion, the small roller -33,'before mentioned, is mounted on a shaft bearings 72. The bearings are connectedby links 73 and 74 with link 52 and are given a timed back and forth movement thereby to enable the rollerto contact with one of the labels. roller to its position against wheel 63 It will be seen that the label holding and feeding mechanism comprises four elongated barrels 30 held by supporting arms v7 6 mounted on a central shaft 77 which in turn 15 mounted in a bearing 78 and carries a 6 provided with inverted tubular members 80 to form variable false bottoms for the labels ,or seals 32. The outer portions of the members 80 are notched. as at 81, to engage with dogs 82 pivotally carried by the lower end portions of rods 83. Said rods are sl'idably mounted bores of the barrelsbetween a pair of 1157 A spring 75 assists in returning the in bearings 84 and are so positioned that when rollers 59 and arms 58 are forced downwardly by cam 47, one of the rollers will be forced downwardly on one of the heads 85' thereby moving one of the rods 83 longitudinally and the pivot dog 82 carried thereby. One of the coiled springs 86 will then raise the rodto normal position again moving the dog which is in engagement with the notches 81 on the barrel and the member 80 will be raised one notch so that the top label in thebarrel may be reached by the sleeve there adjacent. This action takes place on every revolution of the member and in that manner a label is always in position to be fed to the cylinder sleeve. Springs 87, coiled within the confines'of members 80, assist in raising said members.

In order that another ofthe barrels 3 may be swung into position when one has become empty, the bottoms of the portions 88 have elongated shafts 89 hung therefrom,

the lower end portions of which are hooked,

as at 90. It is evident that the hooked portion will be raised as portion 88 israised,

and said hook rides within a slotted member 91 which is formed integral with a short rod 92 projecting through an aperture 93 in the bottom of the barrel. The rod 92 of the barrel which is feeding the labels is normally engaged by a clutch arm 94. However, when the barrel is feeding the last label, the hook will have reached the top of the member 91. Then, when member 80 is again raised, member 91 will also be lifted by the hook and rod 92 will move above the clutch arm 94. This Will permit the clutch arm to be moved to the left by the spring 95 engaging a clutch 96 with a male Geneva cam member 97. Power is transmitted to cam member 97 from shaft 15 by means of a shaft 98 having a bevel gear 99 which is in engagement with a bevel gear 100 on shaft 15. When the clutch is thus in engagement with member 97, the same will be rotated thereby and the arm 101 will engage and move a female Geneva cam member 102 a quarter of a revolution thereby revolving shaft 77. This will bring another barrel 30 into position and its shaft 92 will strike the clutch arm 94 and carry it back to normal position, as shown in Fig. 9, disengaging the clutch. In the manner described, said barrel will stay in position until it has been exhausted of labels and then the next barrel will be moved into feeding position.

In order that the barrels may be removed from the brackets 7 6 so that theymay be filled, spring clips 103, as shown in Fig. 8, are provided. .Tongues 104C, normally held in slots 105 in said brackets are actuated by said clips against the tension of a spring 106.

When all of the barrels 30 have become exhausted of labels, it is desirable that the operator of the machine be notified. For

hold a switch lever 112, as shown in Fig. l,

Obviousl when the barrels are filled thereby keeping the circuit open. However, 7

when the barrels are empty, all of the shafts 92 will be raised so as to clear said switch lever. Hence said lever will pivot to a position to close the switch, closing the circuit and lighting the bulb 107. In this manner the operator of the machine will be notified that the barrels are empty.

From the foregoing description, it will be seen that the improved sealing machine is well adapted for the purposes described.
