SPECIFICATION forming part Aof Letters Patent NO. 7 34,015, dated July 21, 1903.

Y Y, Application filed August 22, 1902. Serial No. 120,617. (No model.)

To all whom lign/ty concern..- l

Beit known that I, THEoDoRE LVALERIUS, acitizen of the United States, residing at Fort Atkinson, Jefferson county, Wisconsin, have invented certain new and useful Improvementsin Milk-Can Washers, of which the following is a specification.

This invention relates to machines for washing and scouring cylindrical receptacles, and particularly milk-cans and the like.

The object of the invention is to provide a machine by means ofA which milk-cans and the like may be very thoroughly and quickly mechanism forvwashing the interior of the can and whichmechanism is adapted to be; expanded to such an extent as to clutch the washed and scoured.

The particular object of myinvention is to provide a simple, compact, and easily-opererated can-washin g machine.

My invention is chieiiy characterized by a rotary shaft carrying a plurality of brushes and means whereby said brushes may be distended after the can has been placed over the end of the shaft thatbears the brushes.

My invention `also consists in a washing- 'machine comprising a hot-water Vat containing and having attached to it brushes for washing the exterior of the can. l

My invention consists, further, in a brus can, so that it will rotate with the brush-shaft for its washing by the exterior brushes; and 4' the invention consists, further, in various details of construction adapting the machine for easy operation and for quick adaptationV to various sizes of cans and in novel combinations of parts, all as hereinafter described, and particularly pointed out in the claims.

The invention will be more readily underl stood by reference to the accompanying drawings, forming a part of this specification, and in which- Figure 1 is a.longitudinal-vertical section of the can-washing machine embodying my invention. Fig.v2.is a similar View showing the canin place with the interior brushes expanded to their full extent, in which position they clutch the can onto the shaft, so that it will rotate therewith. Fig. 3 is a vertical transverse section on the line w of Fig. 2. Fig. 4 is a view of the brush-shaft and inteof the rotating shaft and head. Fig. 5 is an enlarged sectional detail on the line y y of Fig. 4. Fig. 6 is an enlarged section on the line z .e of Fig. 1, showing the square brushshaft.

As shown in the drawings, 2 represents a long vat supported on legs 3 and having a bottom 4 extending beyond the end 5. The length of the vat considerably exceeds twice the length of the cans to be washed, so that there is plenty of room for rinsing the cans after each is freed from the brushes. On the iioor 4 at the end of the vat is a standard 6, and this andthe end 5 are provided with bearings 7 and 8 for the shaft 9. 10 and 11 are the loose andxed pulleys on said shaft for the driving-belt. The inner end of the shaft 9 is enlarged toconstitute the head 12, which fits the neck of the can 13. The shaft 9 and the inner end of the head 12 contain the square hole 14 for the square brush-shaft 15, which is thus guided for reciprocation. The shaft has a slot 16, and the head has a pin 17, extending therethrough and serving as the stopvwhichlimits the vplay of the shaft 15. The shaft 15 is provided with another slot 1S jatright angles to the slot 16 and which accommodates theend of the link 19, which is pivoted on the pin 17. The link does not move .in and out with the shaft, as its inner end is pivoted onthe pin 17 in the head 12.

20 is a brush secured on the end of the shaft 15 for washing .the can-bottom. This brush is of less length than the diameter ofthe neck of the can.

21 is a corner-brush in the form of a right Vangle for washing the corner and side of the can, andrthis brush is secured on the' bar 22, that is connected to the shaft 15 by the

parallel links

23 and 24. The inner end of the bar 22 is pivotally connected to the link 19 by the pin 25.

26 is the shoulder-brush, having the forni of an obtuse angle and connected to the shaft 15 by the extensionvof the link 24 and bythe parallel link 27. The long link or, as it might better be termed, the lever 24, being pivoted on the shaft 15, connects the

brushes

21 and 26, and thus the brush 26 is connected with the link 19, and thereby to the head 12.

ICO

On the outer end of the shaft 15 I provide a grooved collar 28, through the medium of which the lever 31 is connected to the shaft. This collaris secured to the shaft by a pin 29 and has journaled upon it the collar 30, which is provided with trunnions 30', (see dotted lines,) by which the attachment to the lever 3l is made. This lever 31 is connected to the lug 32 on the bottom 4 by a short link 33 and is operated by means of the treadle 34, working through the medium of the link 35, the bell-crank 36, suspended from the vat, and the connecting-rod 37.

3Sisa strong spring extending between the bell-crank 3o' and the leg of the vat and which tends to force the brush-shaft 15 out of the shaft 14, whereby its end brush is moved away from the head 12 and the corner and shoulder brushes are collapsed against thc shaft 15, as shown in Figs. 1 and 4.

The bottom of the vat contains the two long brushes 39 for scrubbing the exterior of lthe can. These are normally immersed in the water with which the vat is partially filled, asindicated. Topermittheadjustmentof the brushes 39 for different-sized cans or to take up the wearin the brushes, I place the brushes upon the metal strips 40, the lower ends of which are fastened to the bottom of the vat, while the upper ends are made adjustable by means of the inclined bolts 41 and the nuts thereon. The rotation of the brushes inside of the can expels most of the water therefrom, and when the interior brushes are only partially expanded the can tends to float upward away from the brushes 39. I therefore provide a top brush 42, arranged on the levers 43, which are pivoted on the side of the vat. This brush 42 has a handle 44, by which the brush maybe forced down onto the can to scrub the body thereof. In addition to this function of the brush it is provided with an end section of long bristles, which reach the small neck of the can to thoroughly wash the same.

4 5 45 are springs extendingT from the treadleshaft 34' to the levers 43 .and which lift the brush 42 when the operator removes his hand.

46 and 47 are respectively steam and water pipes, having valves 43 49 for governing the admission of steam or water. The open ends of these pipes extend downward nearly to the bottom ofthe vat. At points below the valves 4S 49 the pipes are connected by the crosspipe 50, and the steam-pipe contains a nozzle or jet 51, (see dotted lines, Fig. 3,) which terminates opposite the adjoining end ot' the pipe 50.

The operation of my washing-machine is as follows: The tank is filled with water by turning on the valve 49, after which the valve is closed. The steam-valve is then opened, and

the jet of steam, descending in the pipe 4G and creating a strong suction at the end of the pipe 50, soon sets up a rapid circulation of the water through the pipe 47, pipe 50, and pipe 4G and rapidly raises the temperature of the water in the tank, which temperature may be maintained by regulating the steam-jet at valve 4S; This simple contrivance eectually accomplishes the circulation and heating of the water in the tank. The normal position of the parts is as shown in Fig. 1- that is, with the shaft 15 forced inward to collapse the interior brushes. The shaft being set in motion by the belt on the tight pulley, the machine is ready for washing the cans. A milk-can is placed in the free end. of the vat and is partly submerged in water. It is then pushed forward along the side rails or bars 4' and over the collapsed and r0- tating brushes, which effectually clean the neck of the can. After the neck has been thus cleaned, the can being in the meantime held in the hands of the operator, it is then pushed farther over the brushes until the neck of the can passes over the centeringhead 12. Thereupon the operator steps on the treadle 34, and thus through the operation of the lever throws out the brush-shaft 15 and expands the brushes, as shown in Fig. 2. This being done, the can will rotate with the sha ft 15 and head 12. The operator then presses down the top brush 42, and as the can rotates the exterior' thereof will be quickly washed and scrubbed by the

brushes

42 and 39. This operation being completed, the operator will either press down lnore firmly on the brush 42 to stop rotation of the can or will stop the machine and grasp the can by its end and handle, so that he may thereafter hold it against rotation. Then by slightly relieving the pressure on the'treadle 34 he may hold the can whilc the interior brushes,

rotate and rapidly scrub the inside of the can. These operations may take place in reverse order. When the can has been thoroughly cleansed, the operator removes his foot from the treadle 34, whereupon the spring 3S acts to push the shaft 15 inward, thereby throwing or kicking the can off from the collapsing brushes, and the can will float off into the free end ofthe vat, from which it is taken and thoroughly rinsed in any suitable manner.

I prefer to provide two or more shafts 15 of different lengths with different sets of collapsing brushes, and each set Will fit two or more sizes of cans. If the supply of cansof a certain size has been exhausted, the operator will knock out the pin 29 in the shiftinglever collar 30 and also the pin 17, remove the shaft 15, with its brushes, and insert another shaft with a set of brushes suitable for the new size of cans. It is distinctly advantageous to thus adapt the machine for a quick change of brushes. It is obvious that the shaft 9, the pulleys thereon, and the head 12 are in no wise disturbed by the changing of the brushes. It is also obvious that numerous modifications of my invention will readily suggest themselves to one skilled in the art, and I therefore do not confine the invention to the specific constructions herein shown and described.

Having thus described my invention, I
