BOTTLE-WASHING MACHINE.

Patented Oct. 1, 1907.

Application filed August 4, 1906. Serial No- 329,154.

To all whom it may concern:

Be it known that 1, DAVID E. SHAW, residing in Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented new and useful Improvements in Bottle-Washing Machines, of which the following is a description, reference being had to the accompanying drawings, which are a part of this specification.

This invention has for its object to provide a machine for thoroughly cleaning bottles on the interior and the exterior, the bottles being placed on guides and forced upon rotary brushes into a locking position where they receive an injection of cleaning liquid with which the rotating brush cleans the interior and being turned by the frictional contact of the rotating brush to clean the exterior by bearing against the guides in a cleaning solution.

The invention has for an object to provide a novel means for driving a series of rotating brushes from a common source of energy by belting them together by a belt which crosses between the pulleys of the succes sive brushes Another object of this invention is to provide for automatically starting the injection of cleaning liquid into a the bottle as the bottle is forced onto the rotary brush and for automatically stopping the flow of cleaning liquid when the bottle is removed from the brush, the bottle being adapted to be locked on the brush in a position to continue the injection of cleaning liquid and serving to discharge the same into a separate receptacle from that in which the bottle body remains.

With the above and other objects in view the invention consists in the bottle washing machine herein claimed, its parts and combinations of parts and all equivalents.

Referring to the accompanying drawings in which like characters of reference indicate the same parts in the several views; Figure 1 is a plan view of a bottle Washing machine constructed in accordance with this inven tion; Fig. 2 is a sectional elevation thereof taken on the plane of line 2-2 of Fig. 1; Fig. 3 is a transverse sectional view thereof taken on the plane of line 3-3 of Fig. 1; and Fig. 4 is a central sectional view of one of the tubular spindles with its rotary brush.

In these drawings 6 represents a pair of tanks which may be separate as shown or otherwise. A feed pipe 7 extends between the tanks and is rigidly supported in place in any suitable manner with a counter shaft 8 journaled thereon. The counter shaft is provided with a belt pulley 9 to be belted with any suitable driving mechanism and a grooved pulley 10 for driving a series of rotary brushes. The feed pipe 7 connects with any suitable source of supply of cleaning liquid underpressure, preferably with the water mains, and at intervals has T-connections 11 connected by couplings 12 with .i-connections 13 which form journal bearings for tubuend of the series which is carried by a frame 18 slidably i mounted on the feed pipe 7 so as to move toward or away from the series of pulleys 15. This pulley 17 forms a belt tightener and is given a tendency to move in the direction to keep the belt 16 tight by being connected with a weight 19 suspended therefrom by a cord 20 passing over a pulley 21 on the end of the feed pipe 7.

The T-connection 13 for each tubular spindle 14 is more than a mere journal bearing therefor as it serves to establish communication between the interior of the tubular spindle and the supply pipe 7, the tubular spindle being provided with perforations 22 which come into register with the opening leading from the supply pipe and the ends of the bearing being protected by right and left hand packing glands 24 to pre vent the escape of liquid therefrom. The pulley 15 by abutting against a packing gland 23 on one side of the bearing prevents a longitudinal movement of the tubular spindle in one direction and a set collar 24 on the tubular spindle prevents a longitudinal movement in the other direction by abutting against the other packing gland.

The ends of the tubular spindles 14 are reduced in internal diameter to form shoulders or valve seats 25 and a tubular stem 26 fits in each of these reduced end portions with an enlarged head at its end forming a valve 26, there being openings 27 in the stem a short distance from the valve to establish communication between the tubular spindle and the stem when the stem is forced inwardly to move the valve 26 from the valve seat 25. The inward movement of the stem is limited by a set pin 28 thereon riding in a longitudinal slot 29 of the tubular spindle, this arrangement also serving to cause the stem 26 to rotate with the tubular spindle. The "tubular spindle has tufts to constitute a rotary brush 30 and at the forward end there are inclined openings 31 in the stem 26 to discharge cleaning liquid into the bottoms of the bottles when they are placed on the brush and forced against the end of the stem so as to open the valve 26.

The. tanks 6 are divided by partitions 32 near one edge thereof, the main portion of the tank being intended to contain a strong alkaline solution and the narrow space between the partition and the edge of the tank next thereto being adapted to discharge through spouts 33. Within the main portion of the tanks and beneath each rotary brush there is a V-shaped guide 34 connection 16 to cause the rotation of the rotary brushes 30. These brushes dipping into the alkaline cleaning solution in the main portion of the tanks take up some of the cleaning solution so that when a bottle is forced along a guide 34 and onto one of the rotary brushes, the alkaline cleaning solution is carried into the bottle and the brush rotating therewith removes the foreign matter from the interior of the bottle, and as the bottle is pressed against the end of the brush stem to open the valve 26 a supply of water or other cleaning or rinsing liquid is injected into the bottle through the openings 31. The engagement of the head of the bottle with a V-shaped notch 35 of the partition 32 serves to hold the bottle in the position where it will keep the valve op en and allow of the cleaning operation to continue while the operator proceeds to place another bottle on the next rotary brush in a like manner. I

Besides the bottle becoming thoroughly cleansed on the interior, the friction of the brush therewith causes it to turn in the guide, and the guide bearing against the outside of the bottle with the assistance of the alkaline solution in the tank removes the label and all other foreign matter so that the exterior of the bottle is also thoroughly cleaned.

While the liquid injected into the bottles is referred to as a cleaning liquid and may be a chemical preparation for more thoroughly removing foreign matter from the interior of the bottles than would be the case with water, it is obvious that hot or cold water or another rinsing liquid may be employed with the function of rinsing the bottle after the cleaning liquid has been used therein by the rotary brushes.

When the brushes have all been supplied with bottles, the operator then begins to remove the bottles first placed in position and replace them with other bottles to be cleaned, the number of rotary brushes provided for each operator being as many as are required to allow each bottle to remain in place the desired length of time.

With this apparatus the alkaline solution with which the bottles are washed on the interior and also on the exterior is not diluted by the rinsing liquid, for the Water passes from the mouths of the bottles into the smaller compartment of the tank and is discharged through the spouts 33.

What I claim as my invention is 1. A bottle cleaning machine, comprising a tank containing cleaning liquid, a rotary brush dipping in the cleaning liquid and adapted to have a bottle placed thereon, means for injecting a liquid into the bottle when the bottle is forced onto the brush and means for keeping the injected liquid separate from the liquid in the tank.
