MILK-CAN WASHER.

Specification of Letters Patent.

Application filed October 1, 1918. Serial N o'. 256,464.

To all whom 'it may concern.'

Be it known that I, CHARLES A. CHRIST, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Milk-Can Washers, of which the following is a speciiication.

My invention relates to a washing machine for milk cans and the like.

It is an object of this invention to provide a washing machine which will wash the interior and exterior of the milk can in one operation while the milk can is held stationary.

My invention consists inthe construction, combinationand arrangement of parts here.- inafter described and claimed.

In the accompanying drawings, which form a part of this speci c L trated a preferred embodiment of my invention, and in which- Figure 1 is a vertical longitudinal section takenV on line 1-1 of Fig. 2.

Fig. 2 is a vertical section taken on line 2-2 of Fig. 1.v

Fig. 3 is a rear elevation of my apparatus.

Fig. 4 is a lan view of the can carriage and guide rai s. A Y

Fig. 5 is a sectional detail 'on line 5 5 of Fi 4. v

Fig. 6 is a sectional detail of the bumper mechanism on line 6-6t0f Fig. 4. g

Fig. 7 is a plan of the steam coil used in heating the water in washing.

- Fig. 8 is a side elevation ofthe apparatus showing the cover washing com artment looking in the direction indica arrow in Fig. 1.

Referring to the drawings, 10 is a tank, preferably constructed of sheet metal, whose rear portion is providedwith a hood 11 having a vapor outlet 12. The top of the front portion of tank 10 is open, the bottom 10 of the front portion of the tankbeing inclined upwardly toward the front, as clearl shown in Fig. V2. A vertical partition wa 113 divides the tank 10 into a washing compartment 14 and a rinsing compartment 15. The

partition 13 isprovided with an overow' orifice 16 which will keep the water level constant at that height in the rinsing compartment, and an overiiow pipe 17 in the washing compartment 14 located at atrie lower level than aperture 16 affords an outlet for the washing water. A valved steam coil 18 disposed at the bottom of washingy compartment 14 heats the water therein, the

ation, I have illus.

-30 to the by the outer end of the steam coil being open and extending through partition 13 into Icompartment 15.

The guide rails, can carriage and revolving paddle mechanism are identical in both compartments, it will therefore be necessary to describe only those in the washing com- 22 are supports for the guide rails spacingthem. from the bottom of the tank. y A can carriage 23 is slidably4 mounted on the guide rails 19 andcomprises a pair of axles 24 having a curvature tov conform to. the shape of the milk can. The ends of the axles passthrough longitudinal slots 25 provided on the adjacent sides of the tubular 'guide rails 19 and are provided with rollers or wheels .26 which travel inthe interior of the tubular guide rails 19. 27 are a pair of crossbars connectin the axles 24. 28 are braces connecting t e crossbars 27 to the front axle 24. The front axle 24 has bolted -thereon on opposite ends a curved bracket handle 31 is rigidly secured to the middle of 4the U-shaped ro'd 30. '32-are a air of braces connectin the corners of the -shaped rod andle 31. A semicircular bail 33 is rigidly secured -about midway of the leg portions of the U-shaped rod 30 for holding 'the can stationary during the washing operation. Each end of the guide rails 19 is rovided with a bumper mechanism 34. his

bumper consists of a screw cap 35 fitting on the extreme end of the guide rail -19 and having a cylindrical tube 36 secured therein for the reception of a helicalA compression ring 37, the outer end of whichl encircles t e stem 38 of a lunger 39. The bumpers 34 act as shock a sorbers for the can carriage 23. f

` 40 is a bearing mounted on the rear wall of tank 1'0 in which a shaft 41 is journaled. 42 are pulleys mounted on the shaft 41 for the transmission of power. In axial alinement to tlie shaft 41 is a paddle 42'. Fast to the shaft 41 are a plurality of arms 43 extending at 'right angles thereto carrying paddles 44,1;he outer ends of the puddles 44 VPatented May 20, 1919. I

rinsing pocket 49 is provided on the side of the rinsing compartment 15. Hooks 50 on the Wall of the tank 10 serves to suspend cover supportingv rods 51.

In the operation the

compartments

14 and 15 are iilled With Water anda detergent compound is added to the Water in Washing compartment 14. The Water is heated by means of steam coil 18. The can 52 to be Washed is placed horizontally upon the can carriage 23 which is held on the inclined portion 20 of the guide rails 19 by means of hook 46. The handle 31 is lowered from the upright position shown in Fig. 1 to the horizontal position shown in Fig. 2, so that the can engaging bail 33 firmly clamps the canin position on the carriage. The hook 46 is released and the carriage slides dovvn to the outer end of the guide rails, the bumpers34 engaging the front Wheels 26 of the carriage and acting as shock absorbers as will be understood. The disposition of the guide rails and the paddles is such that the Acentral paddle 42 Will enter through the open neck of the can and be disposed along its central longitudinal axis. The outer paddles 44 Will surround the can, the carriage 23,` and the free end of the guide rail 19, being spaced therefrom a suitable distance. i

The agitation produced `by the revolving paddles Will quickly Wash the interior and exterior sides of the milk can. The carriage is then Withdrawn and the can is transferred to the rinsing compartment 15 Where it is rinsed in hot clear water by a similar operation. The' water level, it should be noted, is such that when the can isbeing Washed it does not extend clear u of the neck of the can, thus leaving an air space in the can. When the carriage is With- J, drawn onto the inclinedV portion 20 of the guide rails 19, the Wash Water will iow out throuh the open end of the milk can 53. T he o ject of having the Waterlevel below the roof of the mouth of the can 53 when thellatter is in position to be Washed is to affordfree ingress and egress ofthe Water to the can.

The can cover 53 is placed in the Washing pocket 47 and washed by the' agitation lcan stationary thereon, an agitatin to the upper end of the Water produced by the revolving paddles. When Washed the same is transferred to the rinsing pocket 49.

Various changes in the construction, com bination and arrangement/of parts may be made by those skilled in the art Without departing from the spirit of my invention as claimed.

A Washing machine for milk cans and the like, comprising, a tank, a pair of parallel guide rails consisting of a downwardlyinclined front portion and a horizontal rear portion; a 'can carriage slidingly mounted on the guide rails, said carriage comprising a curved can supporting bed and Wheels rotatably mounted in said guide rail, a carriage shock absorber means arranged at the end of the horizontal portion of the guide rails, a U-shaped rod pivoted on opposite sides of the can carriage; a semicircular can holding bail rigidly mounted on the U- shapedrod, a handle for operating said U- shaped rod, a plurality of revolving paddles -agitating the Water Within and Without the can to be washed, and means for operating said paddles.
