CAN-CLEAN ER.

SPECIFICATION forming part of Letters Patent No. 563,505, dated July '7, 1896.

Application filed January 27, 1894. Serial No. 498,253. (No model.)

To all whom it may concern.-

Be it known that I, HERBERT MGGORNACK, a citizen of the United States, residing at Elgin, in the county of Kane and State of Illinois, have invented a new and useful Improvement in Milk-Oan-Scouring Machines, of which the following is a specification.

My invention relates to an improvement in the class of machines for scouring and rinsing milk-cans in which is employed a rotary handle provided with a brush at the end inserted into the can.

My primary object is to provide a construction of the brush device on the insertion end of the rotary handle whereby it shall be readily adjustable to make the desired scouring contact with all parts of the interior surface of the can, and particularly the scams or corners, and also the constricted or shoulder and neck and funnel-mouth portions. My object is also to provide a peculiarly simple and desirable construction of brush for use in my improved machine; and it is fur.-

ther my object to provide an especially desirable novel construction of stand for supporting a milk-can while undergoing the washing operation with the brush apparatus, also having its bearing on the stand.

My invention consists in the general construction of my improved can-scouring machine; and it also consists in details of construction and combination of parts, all as hereinafter described, and pointed out in the claims.

Referring to the accompanying drawings, Figure 1 is a view in longitudinal sectional elevation, showing my improved machine as it appears in operation. Fig. 2 is a section taken at the line 2 on Fig. 1 and viewed in the direction of the arrow. Fig. 3 is a view of the end of the brush device which is inserted into the can. Fig. 4 is a section taken at the line 4 on Fig. 3 and viewed in the direction of the arrow. Fig. 5 is a view of one of the brushes, representing the manner of forming it and showing it separate from the holder. Fig. 6 is a sectional view, partly broken, the section being taken at the line 6 6 on Fig. 3 and viewed in the direction of the arrows. Fig. 7 is a view, mainly in longitudinal section through the handle portion of the brush device, showing the internal rotary and lengthwise-reciprocating brush adjust ing and operating stem and the means for reciprocating it. Fig. Sis a section taken at the line 8 on Fig. 7 and viewed in the direction of the arrow.

A is the scouring device, the preferred construction of which is that illustrated and described as follows:

On one end of a bearing, shown as and affording a tubular handle B, is swiveled a nipple 1', having a disk head 0", through the center of which passes the operating-stem O in the handle and which should be mainly cylindrical in shape but rectangular in crosssection, as shown, where it passes through the head 7" in order to cause the latter to rotate with it and permit the stem to be readily reciprocated longitudinally through it. The end of the stem adjacent to the swivel connection with the tubular handle is fastened in the socket q of a spider, the diverging arms 19 of which incline slightly forward and terminate in cross-heads 0. (See, particularly, Fig. 3.)

D represents the brush-holder, of which three are illustrated, though any desired number-thus fewer or more-may be employed without departure from my invention, provided the connection thereof with the stem 0 be such as to adapt it or them to be r0- tated therewith and swing pivotally back and forth in the direction lengthwise of the handle. Each brush-holder comprises a socket 1), shown as substantially rectangular in shape, though of course the shape should be such as to conform to that of the brush m it is provided to hold, whatever that may be. Each socket D is flanked by rearward-extending converging arms Z, between which is pivotally fastened one end of a link Z, hooked at its opposite end into the swiveled nippler,

and the cross-head 0 on each arm 19 extends between the adjacent sides of a pair of the brushsockets and is pivotally fastened thereto.

The preferred construction of the brushm is that illustrated in Fig. 5, comprising an originally straight bunch of the brush material, (bristles, broom-corn, or the like,) bent upon it elf at the center and stitched and the bend, into the socket D and ed. The end of the brush on is cut to the V shape illustrated to present expanded surfaces, at opposite sides of the apex, to the can'surface when they are brought to bear against the latter, while, when ex tended to enter the scams or corners of the can, the wedge shape of the brush end adapts the latter to be compressed the better into the seams, thus enabling the brush to be applied the more thoroughly. On one side of each socket 1), I furthermore provide, for a purpose hereinafter explained, a smaller supplemental brush, comprising a socket D in the form of a longitudinally-slotted tube, into which, from one end, the brush on, formed like the brush m, but smaller, is inserted and fastened, as by driving a nail a between the folds near the bend, to spread them apart and thus wed go the brush in its socket, which should be pivotally fastened to its holder D.

The stem C extends through the outer end of the tubular handle 13, where it is provided with an operating crank-handle E, if the ma chine is to be operated by hand, or with any other suitable operating means. Near its outer end the tube B has a longitudinal slot 7:, coincident with which is a rack 2', Fig. 7, on the stem confined endwise between collars 1", whereby it may be rotated without interference from the rack, and a pinion h is supported to engage the rack (and bears against the latter to hold it in place) in a bearing h on the handle B and is provided with an operating-handle h. The rack 2' projects through the slot from a tubular body 7L3, surrounding the stem Cinside the hollow handle B, and the collars i, which are fast upon the stem, bear against the tubular body of the rack at its opposite ends to confine it against independent sliding movement.

As a convenient medium for the applica tion of my improved can-scouring implement, (though it maybe differently applied without departure from my invention,) I provide a stand F, having a top F inclined to a degree that will support a milk-can G, imposed thereon (with its rear portion resting on a concave seat g, its upper band tresting on a bearingstrip g and one of thehandles o confined between a pair of lateral stops g in position to extend its longitudinal center in about a horizontal plane, in line with which, on the higher end of the top, is a bearing f for the handle B. About at the point of the top F, to which the mouth 6 of the can reaches, I provide a basin F to prevent slopping over of the cleansing-water and having an outlet-pipe 61 extendin g downward from it to direct the water into any suitable receptacle (not shown) placed in position below the stand. At the dish is also sh own a vertical annular stationary band F to receive the flaring mouth of the can, which is held in place at its base end by a spring-catch c on the bearing g.

YVith a milk-can placed to be scoured in the position indicated in Fig. 1 and the scouring implement adjusted loosely in its bearing f, the securing operation is performed as follows, with water introduced into the can: The radial limit of extent of the brushes 011, when at right angles with the stem 0, is such as to cause them to bear against the inner side of the cylindrical portion of the can, and to bring them to that position the stem 0 is .moved longitudinallyin the proper direction by turning the pinion h, whereby the pivotal spider or hinge connections of the stem with the brush-holders I) work them on the pivotal connections of the arms '1 with the links 1.). These connections, as will be seen, enable the rotation of the stem C to freely rotate the brush device while the tubular handle B may be moved longitudinally back and forth, and thus the brushes thoroughly scour the interior of the milk-can, and they also enable, by longitudinal reciprocation of the stem, while rotating it, the radial direction of extension of the brushes m with relation to the stem as their center, to be varied to any desired point within the nearly one hundred and eighty degrees of their capacity of adjustment, as indicated by the dotted lines in Fig. 1. Thus the brushes may all be caused to extend inward with relation to the can parallel with the stem, when they would all be bunched together for securing the can-bottom. Then they may be caused to flare toward the canbottom at such an angle as to introduce them into the seam or annular corner junction between the base and cylindrical body of the can. By causing them to flare in the opposite direction they may be extended into the corner forming the junction between the cylindrical body and conical shoulder portion 2), and by still further contracting them and withdrawing the handle, so as to bring them against the surface of the conical shoulder portion, it may be thoroughly scoured. To scour the interior of the neck portion Z) of the can, the handle B is withdrawn to bring the brushes m into that part; but they are then adjusted to extend parallel with the handle in the backward or outward direction, in which position the scouring is performed by the supplemental brushes m, the pivotal fastening of which adapts them the better for the work.
