Witnesses: Innen tor,

delivery end of vintermittently turned shown in Fig. 3, and these trays orcrates are placed one after another on the rails b/ next to the feed door y' over the tank a..

To return empty trays or crates from the delivery end to the receiving end of the apparatus, track rails g and guides h ai'e provided above the hood or cover, as shown in Figs. 1, 3 and, 4, the ends of these return rails and guides being preferably inclined downwardly as shown in Fig. 1. The track rails are provided at intervals with rollers p to facilitate the movement of the bottle trays or crates thereon.

To automatically feed the loaded trays or crates into the apparatus, to transfer them from one carrier to the next, and to discharge them from thelast carrier at the proper times, a reciprocating feed bar g passes lengthwise through the a paratus b'e-` tween, parallel with and a littllej below the track rails g. This bar is provided at intervals with lpivoted dogs r, which foldfor swing from an upright position toward the the apparatus, and are held normally in an upright position against their lateral tail pieces r by springs s. At the delivery end of the machine the bar g is bent downwardly and provided at its lower end with roller guides t, which run on a horizontal guide rail u parallel with said bar, as shown in detail in Fig. 9. For intermittently moving the bar g back and forth..the distance required to carry the bottleotrays or crates into the apparatus, transferv them from one carrier to another, and finally discharge them at the delivery end of the apparatus, alink belt v provided with a tooth w, is mounted on sprocket wheels parallel with said bar,which is provided with lugs y and 2 in the path of the tooth w.

The rotary bottle carriers are intermittently turned a distance corresponding with the distance between adjacent rows of racks, by a mutilated gear 2, which meshes with a pinion 3 on the shaft n,and the link belt v is the distance of one complete circuit While the rotary carriers are at rest by a similar mutilated gear 4, which meshes with a pinion 5 on a shaft connected by bevel gears 6 and 7, as shown in Figs. 2,

.3, and/with the shaft of one of the sprocket wheelsiiie The gears 2 and 4 are fixed on a shaft parallel with the shaft n and provided with a worm gear 8 meshing wit;l a worm 9 on a transverse shaft which is Vpi'ifvided with a pulley 10, as shown in Figs. 3v and 5. As shown in Figs. 2, 3, 5, 6, 7 and 8, each of the piiiions and 5 is associated with a shoe 11, having a fixed relation thereto and adapted after each complete revolution to engage with the periphery of a flange 12 on the driving gear and to prevent the pinion from V'turning when it is not engaged by the teeth of the driving gear. The toothed portions of the two driving gears 2 and 4 are so arranged thatl while one pinion is being turned, the other is held stationary.

The pulley 1() on the worin shaft may be driven iiom an)T convenient source of power. As shown in Figs. 3 and 5, it is belted to a pulley 13 on a shaft 14, extending across the delivery end of the apparatus, and )rovided with a driving pulley 1.5 and a chitc i 16, operated by a lever 17, for starting and stopping the mechanism.

A`water supply pi )e 18, provided with a valve 19, is connected with the several tanks a, and c at the bottom by branches which are provided with valves 20. A drain pipe 21 provided with a valve 22, as shown in iig. 1, connects with one of the branches in such a way that either the tanks a and c or the tank b can be drained when the valve 19 is closed, by opening t'he proper valves 2() and the valve 22.

The tank c is provided with an overflow pipe 23, which prevents the water from rising above the desired level in any of the tanks, the tanks a and c being connected with each other as hereinafter explained, and the middle tank b having an overflow connection 24 into the tank a., as shown in Figs. 2, 4, and 7,

Each of the tanks a and c is partially divided by a central vertical partition 25, arallel with the axis of the rotary bottle carriers, into two subdivisions, in which the water may be maintained at different teinperatures. The subdivisions on the descending side of the carriers are connected by circulating ipes 26 and 27. The pipe 26 opens direct y into the bottom of the tank a, but hasan extension 28 leading upwardly into the tank c and terminating therein above the lower edge of the partition 25. The pi ie 27 opens at its ends into the ii per parts of said tanks. A constant circu ation of water through the subdivisions of the tanks a. and c with which the pipes 26 and 27 directlycommunicate, is maintained while the apparatus is in operation, by a small propeller wheel 29 in the ipe 27. This wheel may be driven from t ie main shaft 14 by connections substantially as shown in Figs. 2, 3, and 8. By this means substantially the saine temperature is maintained in these subdivisions of the tanks a and c. The middle tank I is provided as shown in Figs. 1, 2, 7 and 8, with steam pipes or coils 30, for heating the water therein, and the water is agitated so as to keep it at approximately the same temperature throughout the tank by a pro ieller wheel 31, which may be connected with and driven from the main shaft 14, as shown in Figs. 2 and 8.

To prevent the ivotally suspended racks from swin ing, an to hold their track rails g in line wit i the stationary track rails g, vertically movable shoes or plates 32 are connected with the hood or cover, as shown in Figs. 1, 4 and 5, and are pressed downwardly by springs 33 against the horizontal facesvon The tooth fw passing back on the under side the up er sides of the yokes f at one or both of the belt v, engao'es with the lug a and ends o said racks as they are broughtv into line with the doors y' and j.

-A perforated pipe 34 is arranged acrossv the upper part of the tank c in position to direct a spray or stream of Water against the bottles on the ascending side of the carrier in said tank, asA indicated in Fig. 8 and is connected by a pipe 35 with a branch of the supply )ipe 18, said pipe 35 being provided witli a valve 36.

The greater portion of thetanks a, b and c may be located below the operating floor, which is indicated in F igs. 1, 3 and 4 by the lines 37. j

In the operation of the apparatus the water in the middle tank or compartment b is heated to and maintained at a pasteurizing temperature of about 140 F. by the steam pipes or coils 30. The water in the'subdivisions of the tanks or com artments a and c on the descending side o the carriers (indicated by arrows) is maintained at about4 110 F., whilel the .water in the remaining subdivision of thetank a ris maintained at about 140 F., and the Water in the remaining subdivision of the tank c is maintained at about 88 F. Although thev temperatures in the different parts of the apparatus may be varied somewhat without materially affecting the results attained, those above stated have been found in practice suitable for the purpose. The driving mechanism being set 1n motion, the rotary carriers are intermittently turned together in Vthe direction indicated by arrows, bringing` one row of racks after another into line with the doors and j. The bottles containing the beverage to be asteurized are taken from the filling mac 'ne and placedl in trays or crates o on the stationary track rails g next to the receiving tank a, the first tray or crate being placed so that the dog r at the adjacent end of the feed bar g will standy u i behind. it, as indicated in Fig. 1, when said bar is in its normal position. While the rotary carriers stand at rest with a row of racks in line with the doors and j', the feed bar g is advanced b the engagement of the tooth w on the lin belt v with the lug y on feed bar q, said belt being driven intermittently by the `mutilated gear 4 hereinbefore described, so that the tooth w makes a complete circuit at each movement, starting from about the point where it is shown in Fig. 1, clearing said lug` ly at the limit of the advance movement of said bar and leavin the lug z, as shown in Fig. 0, in the path o the return movement of said tooth on the under side of the belt. By this advance movement of the bar g, the first tray or crate is carried into the uppermost rack of the carrier the tank a, opening vthe door j, which closes behind it.

moves the bar g back to its original position,

lthe dog 7' at its opposite endvbeing turned back against the tension of its spring s so as to pass under the tray or crate just deposited in the adjacent carrier. Trays or crates filled with` bottles are placed one after another in position to be fed into the apparatus, as .he foregoing operations are repeated. After making 'a complete circuit through the receiving and warming tank a, each tray or crate of bottles which has been gradually raised to or approximately to a pasteurizing temperature, is transferred automatically by the feed bar q into the second carrier, wherein it makes a complete circuit through the pasteurizing tank b and is held for a certain eriod at the pasteurizing temperature. rom this carrier each tray or crate of bottles is transferred in like manner by the action of the feed bar q into the last carrier, wherein it makes a complete circuit through the tank c, its temperature beinggradually lowered till it isy in proper condition for delivery from the apparatus. From the last carrier each tray or crate of bottles is discharged upon the stationary track rails g, opening the door y" which closes behind it at that end of the ap aratus. Here the bottles are removed from t e trays or crates, and may be conveniently assed directly to a labeling machine, t ereby avoiding, as in the feeding of the pasteurizing apparatus directly from the bottling inac lne, unnecessary handling. The empty trays or crates are returned to the feeding operator upon the elevated track rails g. As the trays or crates are transferred from one carrier to another, and discharged from the last carrier, their laces are taken by other trays or crates, w ich are fed into the apparatus, advanced from one carrier to the next, and finally discharged from the last carrier by the action of the feed bar g and its dogs r during every stop of the carriers. If 'crates or trays of freshly filled bottles are supplied by the feeding operator so that a tray or crate will be fed into the apparatus every time the carriers stop,` the apparatus will be kept filled, and a tray or crate will be delivered from tho apparatus at each stop of the carriers. As the heated bottles received into the last carrier from the pasteurizing tank b descend in the tank c, they are gradually cooled, imparting` their heat to the water in that subdivision of the tank. Water thus heated and tending-to lrise, is forced by the. propeller 29 through the pipe 27 into the upper part of lthe corresponding subdivision m tank a, where it is utilized to gradually warm the cool bottles and their contents as they descend in that tank. The water being thus cooled and tending to descend in this subdivision 4of the apparatus, is conveyed back through the pipe 26 and its extension 28 into the corresponding subdivision of tank c, where it agam serves to cool the bottles and their contents as they descend therein.

By extending the return pipe 26 upward in the tank c above the lower edge of the partition 25 on the side next to that with which the pipe 27 is connected, the water in the subdivision on the opposite side of said partition is kept cooler. As the bottles ascend in tank c, they are subjected to sprays or jets of fresh cool Water from the ipe 34, the su ply of such walter being regu ated by the va ve 36, so that the bottles and4 their contents as they are delivered from the apparatus, will have the desired temperature.

The apparatus as herein shown and described may be used to advantage for soaking,

cleansing and sterilizing bottles or the like and sterilizing the contents of bottles, or

the like, as Well as for pasteurizing. Various modifications in the details of construction and arrangementof parts of the apparatus may be made without materially affecting its Y mode of operation and without departing from the principle and scope of the/invention.
