1 Claim.

My invention relates to bottle washing in dairies `and has forits object to provide a new eflicient and economical bottle washer which washes the bottles with a brush and rinses them afterward to place them in condition for further use. A further object isto provide a bottle washing and rinsing machine in which a plurality of bottles may be placed in la case and washed and rinsed in the same machine. Y f A still further object is to provide a bott washer having `a slidable` bottle casein which the bottles 4are'placed, which case is then closed and moved forward to contact the stationary rotating bottle` washing brushes and which case is then withdrawn and dropped over vertical rinsing tubes where the bottles are rinsed. Y

`A still furtherobjeotis to provide a bottle washer which will clean the bottle inside and outside with a. strong lye solution, and which bottle is held stationary while-the cleaning brush revolves therein "with forced draft of `washing liquid through the `'core of the brush into the bottle, and which' bottle may then be released slightlyrand allowed torevolve by the motion ofthe brush, washing the outside ofv the-bottle on cleaning strips or brushes, carried in the bottlecasalp l f` i e These objects I-'accomplish with thedevice illustratedin the accompanying drawings in which similar numeralsvand letters ,of reference indi- ',catelike parts `throughout the several Views and .asdescribed `in the specication forming a part of' this application and pointed Vvout in the appended claim. e r e i Inthedrawings 1` have shown e s Figure 1 as aside elevation of the device, parts being cut away.` l

`Figure 2 is a` plan View of Figure l with only a` portion of the device shown. A

Figure-.3 is a vertical ysection of Figure 1 showing the bottle holding case.

Figure 4 is a front elevation of the bottle case.

Figure 5 is a Vertical section of a bristle type of washing brush.

Figure 6 is a section of a fabric bag type of washing brush.

Figure '7 is an end view of the driving mechanisrn for driving the rotating brushes.

Figure 8 is a side elevation of a semi-elliptical spring device for driving' the washing solution from the bottles and for lowering the bottle case into the washing tank.

In the drawings I have shown the washing solution tank as A, and the rinsing tank as B.

These tanksare made joined together for cony venience and are provided with guide rails l and 2 on the sides thereof in which I operate my bottle case C. The bottle case C is made of two sections 3 and 4 secured togetherby hinges and each section is provided with a plurality of milk bottle shaped depressions or forms 6, in the shape of half of a Vmilk bottle so that when the two forms are placed together they will completely encompass the milk bottles therebetween. Any number of forms may be made in the case C. In alignment with the outer largest diameter of the milk bottle I provide La hole to receive the open end of outside washing and flushing or rinsing jets.

Onto the back side of each side of the casing 70 C,I provide hand grips 8 by which the operator may hold the two casings solidly together to hold the bottles from rotation therein or the top seotion maybe slightly raised to allow the bottle to rotate within the casing form and each form is provided with either longitudinal brushes 9 `'carried in the casing along each side and across itherbottom ofthe bottle form 6 as shown in Figure 3 orwith a lining of some heavy cloth, said 80 brush :or lining to hold the bottle from rotation vwhen the two forms 3 and 4 are held together.

To wash the exterior of the bottle the upper portion ofthe casing C is slightly raised to allow 'the bottle to rotate therein.

vThe top casing 3 is provided with an overlapping nap 10 along the back side thereof to prevent the washing solution from coming back onto the `operator when the upper half 3 is raised to allow the bottle to rotate in the case C. .The case is provided with suitable rollers 11 on which the case may be moved forward and back over the rails 1 and 2 and the ends of the section 4 of the oase are provided with similar rollers 11` to prevent binding on the sides of the rails when the case is moved.

Along lthe back side of the tank A, I provide two rows of spaced apart aligned bearings 13 and 14 through which bearings, hollow drive shafts 15 are passed. Between the two bearings 13 and 14 on the shafts 15, I provide sheave wheels 15a. Onto the outer ends of the shafts 15, I connect fluid pipes 16 by packing nuts 1'7 being screwed onto the ends of the pipes and carrying the ends of the shafts 15 rotatably therein. The inner ,105 free ends of the shafts 15 are provided with couplings 18 into which couplings the cores 19 of the washing brushes 20 are screwed. The washing brushes 20 may be made of various materials such as bristle, fabric, or any suitable brushing i710 material. The cores 19 of the brushes are hollow to allow the fluid from the pipes 16 to pass therethrough and outlet ports 21 are provided in the cores to allow the solution to be sprayed therefrom into the bottle.

In the type of brush shown in Figure 6 of the drawings a fabric bag 22 is provided with one end closed around the core 23, by a clamp 24. 'Ihe end of the core is enlarged and hollow with ports therethrough to allow for flow of uid therefrom and to prevent puncturing the bag when it is being inserted into the milk bottle.

The fluid pipes 16 are connected together by a pipe 28 and with a iiuid pump 25, which pump is in open connection with the fluid in the tank A. The brushes and fluid pump are driven by a motor M, which motor is mountedadjacent the tank A and has a driving pulley on each end thereof to drive the pump from one pulley and to drive the sheave wheels or pulleys of the drive shafts of the brushes from the other pulley. A belt 26 drives the sheave wheels 15a.

rIhe drive belt 26 encircles the pulley on the motor and is engaged down under the first two sheave wheels, up over the top of the next two, down under the next and up to the motor pulley, rIhis is continued in sets of two where there are more shafts in larger machines. This makes the second set of wheels driven in the opposite direction to the rst set.

A pipe 29 connects the pipe 28 from the pump 25 with outside washing jets 30, which jets are adapted to rit into the holes l in the case C to force fluid into the case around the perimeter of the bottles. When the case is moved forward a valve 31 is operated to open the flow of fluid into the pipes 16 and into the jets 30. The case actuates a bell crank lever 32 which in turn opens the valve, and the valve is provided with a spring to close the ow of fluid when the case is moved back.

The rinsing portion of the device is as follows:

The side rails 1 and 2 are cut at 35 with a false portion 36 set thereinto, said false section being spring supported with the springs 37 adjustable andv of sufcient power to hold the section in place, with the weight of the bottles and case in place, until forced down by the operator.

In the bottom of the tank B, I provide a series of internal and external rinsing jets 40 and 41 respectively, said jets to be turned on when the lease is pressed down until the valve lever 38 -opens the valve 39, turning the rinsing medium into the jets. This rinsing medium may be clear water, steam or a solution used for rinsing.

To rinse the bottles the case C is raised onto its front edge onto the false rail section 26.

In Figure 8 I have shown a spring suspension of the bottle case and this is accomplished by securing two elliptical springs 45 to the rails 1 and 2, and on the ends of the springs 45 I provide depending rods 46 to which a cross foot treadle 47 is secured so that with downward pressure of the foot on the treadle the springs will be flexed downward. I then provide spaced apart rollers 48 and 49 on each end of the case C, said rollers to engage the top side of the springs 45 when the case is withdrawn from the washing brushes. The incline of the springs tips the case forward, and all liquid in the bottles is drained out in the washing solution tank. The rollers raise the vcase C from the tracks 1 and 2 onto the springs, and notches 50 are provided in the top of the springs to engage the front rollers 49 when the case has been drawn back thereto, and when the rollers 49 engage the notches the operator raises the handles 8 of the case, tilting the case to a vertical position as shown in the dotted lines in Figure 8. 'Ihe operator then depresses the foot treadle flexing the springs and lowering the case 6 into the rinsing tank where the bottles are rinsed, by the jets 40 and 41.

The operation of my machine is as follows:

The case C is opened and bottles placed in each form. The case is then closed and moved forward over the tracks until the brushes are in the ends of the bottles. on the fluid and it is forced into the bottles through the brushes and around the bottles through the jets. To Wash the outside of the bottles the top portion 3 is slightly raised until the force of the brushes revolving in the bottles imparts the rotating motion to the bottles and the fabric or brushes 9 in the case C cleans the outside of the bottles.

When the bottles are Washed inside and out,

the case is drawn back until it is over the false f section 36 in the rails 1 and 2 and the case is then turned onto the front edge and pressed down. This compresses the springs and engages the lever 38, turning the rinsing solution into the jets 40 and 41, rinsing the outside and inside of the bottles. The pressure is then released from the case and the springs raise the case again to the level of the rails and the case is set down horizontally on the rails again where it is then opened and another batch of bottles set therein.

Having thus described my invention I desire to secure by Letters Patent and claim:

In a bottle washing device a plurality of rotary brushes vhaving hollow cores with ports through the side wall thereof to spray liquid into the interior of the bottles; a case in which said bottles are carried formed of like forms hingedly connected to receive and engage the bottles therebetween, said case to carry the bottles onto or away from said brushes; means whereby one of said forms may be swung away from the other form to allow the bottles to rotate therein; and means carried in said case to clean the exterior of the bottles.
