Specification of Letters Patent.

Patented July JUL, 1916.

Application filed December 27, 1915. Serial No. 68,641.

To all whom it may concern Be it known that I, EDWARD COURT, a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of lVisconsin, have invented certain new and useful Improvements in Gap- Scrub'bing Elements for CroWn-Corking Machines; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention refers to crown corklng machines and has for its object to providea simple, economical and effective means in connection with the feed throat of such machines forcleansing the inner surfaces of the crown caps as they travel from the hopper in uniform order to the crlmplng head.

In practice it has been found that the crown corks as supplied from manufacturers are more or less coated with fine metallic particles and other foreign matter which accumulate due to the abrasive contact of the caps as they shift about in bulk within the hopper. Hence the foreign particles will accumulate upon the cork disk filler, which filler is thereafter exposed to the fluid contents of the corked bottle, whereby serious contamination of the product results. My invention is designed to overcome these objectionable features, whereby the crown corks are thoroughly dry scoured to render them sanitary by subjecting said caps to an abrasive or scrubbing element.

lVith the above objects in view the invention consists in certain peculiarities of construction and combination of parts as set forth hereinafter with reference to the accompanying drawings and subsequently claimed.

In the drawings Figure 1 represents a fragmentary elevation of a crown-corking machine of a well known type having attached thereto an abrasive element embodying the features of my invention, which element, in this exemplification, is shown in the form of a rotary brush; Fig. 2, an enlarged detail cross-section of the brush mechanism, the section being indicated by line 22 of Fig. 3, and Fig. 3, a cross-section of the same, the section being indicated by line 33 of Fig. 1.

Referring by characters to the drawings, 1 represents the hopper of a crown corking machine having a revoluble crimping head 2 thereunder, which crimping head comprises a centering disk 3 and a series of crimping barrels 4 positioned thereover.

'The hopper is provided with a discharge travel by'gravity to the crimping head. The

crown caps are of the usual type having some form of pliable disk B fitted therein, which is preferably composed of cork. The crimping machine and crown corks form no part of my invention and therefore are not described in detail. The throat 5 is, as best shown in Figs. 1 and 2, provided with an intermediate outwardly bowed section A with the open portion facing outwardly, whereby the caps as they travel downwardly present a clear field for access to their in ner faces which contain the cork disks. The hopper neck has projecting therefrom a revoluble' shaft 8 carrying a drive-pulley 8, whereby motion is transmitted to the scrubbing or abrading element. In this exemplification of my invention the bowed portion C of the skeleton trough 5 has secured thereto a bracket 9 having legs projecting outwardly that terminate with journal boxes 9 in which are mounted a brush spindle 10. One end of the brush spindle carries a comparatively small pulley 8", which is adapted to be revolved at a right angle to the drive pulley 8 and is connected thereto by a twisted belt 11. The brush spindle carries a brush head 10' having projecting therefrom a series of brushing tufts 12, which tufts, when rotated are adapted to enter the juxtaposed bowed portion of the throat 5 and engage the inner surfaces of the crown caps as they travel past a vertical line intersecting the axis of the brush and the axis of the bowed portion C of said throat, the brush being revolved in the opposite direction from that of travel of the crown caps.

From the foregoing description it will be manifest that when motion is imparted to the crown corking machine, this motion is transmitted to the rotatory scrubbing brush, which brush develops comparatively highrspeed and its tufts revolving over the inner surfaces of the caps will'thus thoroughly scrub or cleanse the same from any foreign particles that may adhere to the inner surface of the caps. These particles or refuse which are removed from the caps i not shown.

by scrubbing are :preferably trapped in a collecting hopper '13, which is positioned under the brush, as shown, and the said refuse may be then delivered from the collecting hopper into any desiredreceptacle,

It ispbViousthat, whilelhave shown a scrubbing element vin the form of a tufted ibrush,i"any' suitable scrubbing device other than that -'illustrated may be employed with- .outdeparting from the spirit of my invention. 7

I claim:

1. The combinationof a crown-corking machine comprising a hopper,a crimping head, and a throat leading from the hopper in communication with the head through which 'crowncorks are adapted to travel with their inner surfaces uniformly exposed, and ascrubbing element juxtaposing the feed throat adapted to successively engage the inner surfaces of said caps.

2. The combination of a crown-corking machlnecomprlsmg a hopper, a crlmping in communication with the head through which crown corks are adapted to travel 1.

the feedthroat adapted to successively cngage the inner surfaces of said caps.

3. The comb1nat1on of a crown corklng machine comprising a hopper, a crimping head and a skeleton feed throat 1n communication with the head and hopper, the throat being bowed outwardly-in the direction of its skeleton surface, the said throat being adapted 'to receive crown corks witli their inner surfaces projecting toward the skeleton face of the throat, and a rotatory scrubbing brush uxtaposing the aforesaid skeleton face of the throat for successive engagement with the inner surfaces of the crown j caps as they travel past said brush.

4. The combination of a crown corking ,machine having a hopper, a revoluble shaft projecting therethrough, a crimping head positioned under the hopper, a throat in ..communication with the hopper head having a portion thereof apertured, a revoluble -brush adapted to enter the throat at the apertured portion thereof, a pulley carried by the brush, a pulley carried by the crown corking machine shaft, and a belt connection {between the pulleys.

In testimony that I claim the foregoing I have hereunto set my hand at Milwaukee in the county of Milwaukee and State of Wis- Yconsinin the presence of two witnesses.
