TEMPERATURE-CONTROLLER FOR BOTTLE-WASHING MACHINES.

To all whom it may concern: Be it known that I, GEORGE J. MEYER, citizen of the United States, and resident of Milwaukee, Milwaukee county, Wisconsin,

have invented new and useful Improvements in Temperature-Controllers for Bottleing brushes for cleaning them, and also to the action of sprays of Water for rinsing them, and has for its object to use water of high temperature at that portion of the travel of the bottles in which they are subjected to the action of the brushes to facilitate the cleaning operation and to then subject them to successively cooler treatments of water to radually cool them ofi.

Another 0 ject of the invention is to economize in the use of water in such mechanism by using water over a sin at a more advanced part of the trave of the bottles after it has had its temperature raised by contact with the bottles.

With the above and other objects in view the invention consists in the temperature controller for bottle washing machines as herein claimed and all equivalents.

Referring to the accompanying drawings, 1h which like characters of reference indicate the same parts in difi'erent'views:

Figure 1 is a side view of a portion of a bottle washing machine constructed in accordance with this invention, parts being spread out for convenience to present a diagrammatic representation of the cooling system and,

Fig; 2 is a similar view of the remaining portion of such bottle washing machine, some of the parts of Fig. 1 being duplicated therein.

In these drawin 10 indicates the end of a soaker from which a stream of bottles 11 is conducted b 12. -The bottl verted position in bottle holders 13 on the of hot water 0 means of a chain conveyores are supported in an 1nconveyer and immediately after leaving the soaker 10 are carried beneath a pair of rotary brushes 14 which thoroughly brush and clean the bottoms thereof. As each bottle carrier reaches a position in the intermittent movement of the conveyer midway between the brushes 14, rotating spindles 15 are moved upwardly into engagement with the bottle, necks and force the bottles out of the bottle holders and between the brushes 14 so that the latter serve to thoroughly brush and clean all sides of the bottles rotated by the spindles and particularly the mouth end of the bottles. The downward movement of the spindles 15 returns the bo'ttles to the bottle holdersvand the next forward movement of the conveyor takes place. The cleaning action of the rotary brushes 14.- is igreatly facilitated by sprays approximately 165 F. which are thrown thereon from spray pipes 16.

The bottles are next subjected to a preliminary interior rinsing by nozzles 17, and then to the action of internal cleaning brushes 18 with water sprayed therethrough, and then to a second internal rinsing through nozzles 19. The water supply throughthe'nozzles 17, brushes 18 and nozzles 19 is at a high temperature, in the pres ent case the same as the temperature of water supplied by spray pipes16, approximately 165 F.

The bottles are next subjected to the action of a final internal rinsing water through nozzles 20, and this water is preferably water which has not been used at any other part of the process and in the present instance is approximately 150 F. v

The nozzles 17 and 19 and the bottle sup ports of the spindles 15 and the interior brushes 18 are carried by a vertically reciprocating frame 21 operated in any desirable manner so as to engage the bottles only during the intervals of rest of the conveyer.

An inclined drain sheet 22 conducts the water falling from spraypipes 16 into the soaker 10, while an inclined drain plate 23 conducts the water falling from the brushes 18 and the nozzles 17, 19 and 20 into a screened heating tank 24 containing a steam;

coil 25 and a water coil 26 which contains a water from the heating tank 2% is delivered valve 27 and leads to the nozzles 20. The

by a'rotary pump 28 throu h a pipe 29 containing a valve 30 and supplying spray pipes 16 and. nozzles 17 and 19 and brushes 18. T he valves 27 and 30 have connection with the vertical reciprocating parts which op.- erate the frame 21 so that the flow of water occurs only when the conveyer is at rest.

When the bottles leave the final rinser nozzles 20 they are not again subjected to internal treatment but are permitted to drain and are cooled from the outside by Water sprayed over them first from a spray pan 31 with water at approximately 120 F, then from a spray pan 32 with Water at appoximately 90 F, and finally from spray pan 33 with water received directly from the service pipe 34 at a temperature of approximately l0 to F.

The warm Water from

spray pans

31 and 32 drops from the bottles into a screend heating tank 35 or into an inclined drain plate 36 leading thereto and here it is raised to the desired temperature, preferably l20 F, by a steam heater 3'? controlled by a thermostat 38. wat/er is drawn from this tank 35 by a rotary pump 39 through a valved pipe e0 discharging into the spray pan 31.

Cold Water from the spray pan 83 drops from the bottles into. a screened collecting tank 41 from which it may be drawn by a rotary pump 42 "ogether with a part of the hot water throu h a valved connection (l3 and is forced through a valved pipe lei which discharges into spray pan 82. A thermometer connection 45 in pipe 4A indicates the temperature of the water being supplied to spray pan 32 so that the operator may know Whether to open the valve 43 more or less to maintain the desired temperature.

Each of the tanks 35 and ll is provided with an overflow pipe 1'6 to carry of? surplus .w ater therefrom Thermostatic control of the steam through coil 25 is also provided to maintain the desired temperature of the water in tank 24.

By means or this invention the bottles which are hot when they leave the soaker are notwashed with cold water as usual in order to cool them 0% at once for the filling machine, but they .are washed inside and outside with hot. Water of approximately 165 F. and are rinsed with water of the same temperature and then with cooler water of slightly lower temperature. Throughout the remainder of their travel the bottles are subjected to a cooling operation by which the temperature is reduced gradually in their travel beneath sprays of water becoming cooler as the discharge end of the machine is approached. The long travel of the bottles in their cooling treatment enables them to drain perfectly before they are delivered from the machine for t -e filling operation.

menses It will be understood the the final cold Water is the only new Water used for the cooling of the bottles after they leave the rinsers and that this Water is repeatedly used at the difierent temperatures. Most of the heat required for this purpose is furnished by the bottles themselves and as the pumps have no great resistance to work against very little power is needed. in fact, the entire apparatus requires no more power or steam than is used in the ordinary soaking and washing apparatus. The bottles are kept hot @0111 the time they leave the soaker until the internal rinsing is completed and the washing performed with hot Water is much more eilicient than .washing with cold water. The bottle washing machine of this invention is, therefore, more efiicient than cold water machines and does not involve a greater consumption of Water or a higher cost of operation.

ll desire it to be understood that this invention is not limited to any specific form or arrangement of parts except in so far as such limitations are specified in the claims.

What I claim as new and desire to secure by Letters Patent is:
