REVOLVING BOTTLE-CLEANIN G MACHINE.

T 0 aZZ whom z' may concern.'

Be it known that ANDERS ANDERSEN PIND- s'rorrn, manufacturer, subject of the Kingdom of Denmark, residing at No. 62 Frederiksberg Alle, Frederiksberg, near Copenhagen, Denmark, has invented certain new and useful Improvements in Revolving Bottie-Cleaning Machines, of which the following is a specification.

The present invention yhas for its object an improved revolving bottle cleaning machine of that class or type in which the interiors of the bottles are cleaned by means of brushspindles, mounted radially, independently of one another, in removable bearings around a vertical shaft; the brush-spindles are rotated by said shaft and moved around the` same, so that the attendant, from the positionat which he is stationed relative to the machine, can both insert the bottles on and remove them from said brush-spindles. A machine of this type is shown and described in my prior Patent, No. 9i4,986, granted December :28, 1909, upon which the present invention is an improvement. In such machines, the outer faces of the bottle bottoms are cleaned by means of 4bottomg brushes vpivotally mounted on the brushspindle bearings, while the outsides and necks of the bottles are cleaned by means of one or more revolving brush-rollers mounted above the brush-spindles.

Hitherto, in such machines, the removable bearings of the brush-spindles have been pivotally mounted in a frame which is rotated by friction from the constantly-revolvino,` vertical shaft, while the brushspindles are caused to rotate in their bearings by means of frictionv rollers fixed to the rear of the spindles; these friction rollers, when a bottleis inserted on a brush-spindle, owing to the weight of the bottle vand to the mounting of the bearing, are pressed against a friction. disk fixed to the vertical Vshaft above the bearings.- Such arrangement has, however, the drawback that the brush-spindles, as the friction rollers and the friction disk become worn, will assume a more and more. outwardlyand downwardly inclined position when the bottles are'insert'ed upon them, with the result that the interiors of the bottles will not be equally cleaned throughout, unless the machine-parts exposed to wear are correspondingly adjusted.

According to the present invention, this Specification of Letters Patent.

drawback is avoided by Ymounting the bear ings of the brush-spindles freely and loosely 1n guides carried by the frame, which latter is rotated by friction fromthe vertical driveV shaft. rI`he front end of each of 'the bearings is adj ustably supported upon said frame by means of 'a screw :carried thereby, so that by adjusting said screws, the bearings may be moved up and down, and thereby the positions of the brushspindles may be varied tocorrespond with the dimensions of i -the bottles. In accordance kwith the inven- Vtionthe vfriction rollers of the brush-spindles rest upon the friction disk fixed to the vertical drive shaft, so that wearof the friction rollers and of the friction disk can i ever, several drawbacks, which in the pres` ent invention are avoided by mounting these bottom-brushes and guide-funnels on aspeeial ring carried by brackets fixed tothe l above-mentioned rotatable frame which'supports the front endsof the bearings of the brush-spindlesv and carries the guides for said bearings, so that said 'ring rotatesrwith the bearings. Y Y l 'Ihe annexed drawing illustrates an embodiment `of the invention.

Fig. 2 is a fragmental side elevation; Fig. 3 is a vertical section, vshowing a detail;

The machine consists of a frame a, pro vided at its top with a vbearing for a vertical shaft c, which is constantly rotated, in any suitable manner, as for rinstance by means of the `pulley b, from a main shaft or other source of power, (not shown). The'shaft o carries a frictiondisk (Z, and its lower por- Fig. i is a `fragmental plan view; and Fig. v

tightened together by means of screws and wing-nuts L, these disks z' clamping between them a. toothed ring j which meshes with a pinion Z fixed to a shafty le. The latter, is constantly rotated by means of a pulley le from the main shaft, sorthat the frame g is rotated around the shaft c owing to the friction between the toothed ring j and the friction disks z'.

The brush-spindles m, which serve to clean the interiors of the bottles, are arranged ra- Adially around the shaft c in bearings n, the

front ends of which are adjustably support- -ed with relation to the frame g by means of screws `0 threaded into said frame. The rear .portions of the bearings are freely and loosely mounted in guides p fix-ed to the carries, adjacent to each of the brush-spindles, a pivotally-niounted bottoni-brush t and Ya pivotally-mounted, guide-funnel u; which latter is of the type shown and described in my said patent and acts in the manner therein set forth. The bottoni-brushes are pressed against the bottoms of the bottles and maintained in this position by a 'guide-rail c, (Fig. 4). v

During working, the bottles inserted on the brush-spindles are supported by a ring e, which does not revolve.

The operation of the machine is as follows:-

Before the operation begins, the bearings -ii are adjusted by means of the screws 0 to give the brush-spindles m such a position that the bottles subsequently inserted thereon will be supported upon the above-nientioned ring s. Then the machine is started, and the bottles are successively inserted on During the movement of the frame g, the bottom-brushes z are successively pressed against the bottoms of the bottle by the guide-rail c. The bottle rolls along the rail s; and the brush spindle m is rotated by its friction-roller g, which latter rests upon the friction disk d fixed to the constantly rotating shaft c.

nical effects are obtained:
