This invention relates to a machine for taking bottles from a crowning or other sealing machine, subjecting them to a series that process. In the manufacture and putting up of such commodities as ketchup the bottles are heated to a high degree at the time when they are crowned. -With this machine they can be taken automatically from the crowning machine and subjected to three baths of water for cooling purposes, each bath being a little cooler than the one 1 before and at the same time the bottles can be rotated and tilted along their axes so that the contents will be thoroughly mixed while they'are being cooled. They can be discharged from the machine in a cool enough condition so that they can be packed in cases and shipped immediately, if desired.

The invention also involves an improved mechanism for conveying the bottles back and forth through the tanks, an improved relationship of the tanks, means for keeping them at different temperatures, and mechanism for operating the endless chain conveyors, as well as the'details of the con- 80 veyors and sprockets for driving the same and means for controlling the admission of the bottles into the machine.

Additional objects and advantages of the. invention will appear hereinafter.

Fig. 10 15 a sectional view on the line ketc up bottles which have been crowned in a highly heated state in a'crowning machine, introducing them in a vertical state, resting on their bottoms, into a tankof water somewhat cooler than the contents of the bottles so as to reduce the temperature thereof but not cool enough to crack the glass, tilting them over on their sides in this water. and conveying them along therein in such a wayas to roll them and thereby mix the contents thoroughly while they are traversing the bath. Then I provide means for tiltingthe bottles into vertical position and shifting them from this'bath into a second one at the end of theirtravel. This secondbath is heated to a lower temperature so as to reduce the temperature of the goods still further and yet not present any danger of breaking the bottles. The bottles are rolled alongin this bath and then brought to u right position again which, it will be 0 served further, assists in mixing the contents, and then carried on into a third bath at a still lower temperature to cool them down to normal and further mix the contents in the same way. These three baths are. arranged parallel with each other and the bottles are conveyed through them by three endless chains, the two on the outside taking them in the same direction and the center one taking them back so that they are received at one end of the machine and discharged at the other. This will indicate the general nature of the machine.

- We have provided a general large tank 10 divided into three compartments 11, .12 and 13 longitudinally. These compartments .by water or steam entering the several tanks separately through pipes 14, 15 and 16. The tanks are heated to different temperatures for the purpose above described and the heat is distributed to the water in the tanks by arranging pipes or coils in the bottom of each tank communicating with the several supply pipes as indicated more especially in Fig. 5 or in any other desired way.

The machine can be run in any desired way but we have shown a motor 20 which by pinion, not shown, on its shaft operates a gear 21 fixed on a shaft 22 provided with a pinion 23 for driving a gear 24 runnlng loose on a bushing 90 which is keyed to a shaft 25. Keyed to bushing 90 is a friction disc 91 having a leather disc 92 fixed to 1t. By meansof springs 93 mounted on studs 94 and the friction device the gear 24 drives the shaft 25. On this shaft 25 there is a pinion 26 driving a gear 27 keyed on the main shaft 28 of the machine which is located at the .discharge end thereof. On this main shaft 28 there are three sprocket wheels 33, 40 and 41.

The first sprocket wheel has a hub 29 provided with a disc 30. On this disc are arranged three bolts 31 which pass through arcuate slots 32 in an-annular plate 33. Therefore it will be seen that this annular plate can be adjusted circumferential ly on the hub of the sprocket wheel. On this hub are lugs 34 provided with screws 35 entering lugs 36 projecting from the inner side of the annular plate 33 so that by turning one in and the other out this plate can be adjusted and then the bolts 31 tightened up to hold it in adjusted position. On this annular plate 33 are sprocket teeth 37 so that the plate with the other parts just described constitutes the 'first sprocket wheel. It will be seen that the teeth of this sprocket wheel are adjustable around the shaft to a certain degree.

At the other end of the shaft is another sprocket wheel designated 40 of the same character as the sprocket wheel just de scribed. Intermediate between these two sprocket wheels is a third sprocket wheel 41 j which is of the ordinary kind and not having any adjustment preferably but free on the shaft. 4

Over each' of these sprocket wheels passes a chain.

' only one of themwill be described Each one The three chains are just alike and tegral pairof hooks 46 at one end and with a transverse projecting stud 47 at the other entering the next hooks. Under the plates 44 are spaces 48 that receive the teeth 37 of the sprocket wheel and each link has a transverse wall 49; It will be seen therefore that the three chains 50, 51 and 52 in the three tanks 11, 12 and 13 are operated by three sprocket wheels. The two outer chains and 52 are operated in thesame direction to bring the bottles toward the shaft 28 on the upper strand of the chain. The central chain 51 is moved in the opposite direction to carry the bottles back as will appear.

At the other end of the machine there is a shaft 54 parallel with the shaft 28 and having upon it two sprocket wheels 55 and 56 in line with the sprocket wheels 33 and 40 and receiving the same chains by which they are rotated positively. They are fixed on this shaft 54 and turn it.

gear 58 on a shaft 59 on which is a sprocket wheel 60 like the sprocket wheels 33 and 40 and opposite the sprocket wheel 41 which is loose on its shaft. On account of this gearing the sprocket wheel 60 rotates in the opposite direction to the sprocket wheels 55 and 56 and this is the wheel which positively rotates the endless chain 51 and moves it in a direction opposite to that in which shaft 62. Also on the end of the shaft 54' there is a gear which operates a longitudinal shaft 66 having a sprocket wheel 67 for operating a feed belt 68. The relation between the gears 61, 65 and the number of cam projections on the cam 63 is such that for each bottle fed out of the crowning machine on the endless feed belt 68 the lever 64 willbe operated back and forth. The end of this lever engages a roll 70 mounted on a lever 71. This latter lever has a spring 72 for moving it back and a latch 73 on the end for preventing the discharge of a bottle Also fixed on thls shaft 54 is a gear 57 meshing with a from the conveyor' 68 except when it is drawn back, which is accomplished periodically by the operation of the cam 63. This permits the bottles to be fed from the conveyor 68.

The latch 7 3 is pivoted on the end of the lever 71. One end of the latch 73 projects into the conveyor in front of the bottles. The other end is held .n a groove 74 in a stationary casting 95 by means of an adjustable spring 98 mounted on the lever 71. This looks the lever 71 against moving back. The bottle hits the projecting latch 73 throwing the other end out of the groove 74 in the casting 95 and releasing the lever 71 so it can be moved back by the spring 72 whenever the cam 63 turns toa position to allow that motion. Ordinarily the lever 71 does not move if there are no bottles on the conveyor 68 because it remains locked by the latch 73.

The conveyor 68 is higher than the conveyor 50 and the bottles are tipped over by gravity and fall on their sides on rubber pads 96 between two of the plates of the conveyor 50.

The partof this conveyor which is in position to receive the bottles from the conveyor 68 is elevated as shown in Fig. 4. The bottles are moved along horizontally on the conveyor 50 for a sli ht distance and then the conveyor is allowed to descend by a guide below which supports it so that the bottles are brought down into the water of the first tank 11. As the conveyor, 50 continues to move forward they are rolled along for mixing the contents, as above explained.

,The bottles having passed on down in the tank 11 which is filled with hot water, but considerably cooler than the contents of the bottles, they will roll along inthis tank for a considerable period of time while the contents are being mixed and cooled.

As they come to the other end of the tank the chain is brought up to an elevated posi- -tion and then the bottles continue ,to roll along with their necks resting on a horizontal' ledge or guide plate 77 and their butts against a vertical wall 78. The former gradually rises and forces them up as shown in Fig. 10, to a slightly inclined position. This guide plate continues to pro'ect further into the path of the bottles until it tips them up into the vertical position as shown in Fig.' 9 at the left.

Then there is a slanting deflecting wall 79 located across the conveyor and over the tops of the plates 45 which slides the bottles over to the side as shown in Fig. 2. They are then taken up by a rotating gateor turn-stile 80 fixed on a vertical shaft 81 and driven y from one of the two adjacent chains by the plates 45 thereon engaging teeth 82 on the shaft 81.

. This gate necessarily operates exactly in synchronism with the chains 50 and 51 and its projecting points register with the spacing plates 45 thereof on both sides so that'it moves the bottles around from one chain conveyor to the other, takes them from between slightly inclined position as shown in detail in Fig. 11.

This guide plate continues toproject further until the bottles are tipped over into horizontal position. They are then rolled along in the second tank 12, which is filled with cooler water, until they come to a deflector 79 just as before and are carried by another gate 80 over to the third conveyor- 52 in the same way as described above. Here the bottles have been righted to vertical position and have been deposited on the conthird deflector 79 forces them out of the machine into a receiver 89 from which they can betaken by hand or conveyor, as may be'desired. Y

The bottles are cooled down to normal by this time and their contents thoroughly mixed. It will be seen therefore that in this way the machine provides for automatically feeding the bottles from the crowning machine to the point of discharge, cooling them gradual but constantly and thoroughly mixing t 1e contents practically all the time. The mixing is done not only by rolling the bottles along but by tilting the bottles up to vertical position three times during the process and tipping them down from vertical to nearly horizontal osition three times also.

Although we ave illustrated and described only a single form of the invention we are aware of the fact that modifications. can be made therein by any person skilled in veyorin each tank, means for operating the.

conveyors in theadjacent tanks in opposite directions, whereby the bottles or the like can be conveyed along one tank to the end thereof, and movable mechanical means 210-.
