BRUSH FOR BOTTLE-WASHING MACHINES.

Application filed November 20, 1913.

'To all whom t may concern:

Be it known that I, JOHN M. JUNG, a citin zen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and use= ful Improvements in Brushes for Bottle- Vashing Machines, of which the following is a description.

My invention relates to an improved brush and spindle therefor for washing bottles. In machines of this type, ordinarily from one to twenty or more spindles and brushes are employed upon each washing machine, so that a number of bottles may be Washed at the same time. For economy of space the brushes and spindles are ordinarily set quite close together, so that the brushes should be attached to the spindles in such a Way that they may be easily reached and quickly removed, and in a multiple spindle machine it is desirable that they be removed with as little loss of time as possible. Owing to the wear on the brushes, it is also necessary to frequently renew them.

The present invention resides particularly in an improved spindle and brush therefor, which brush may be easily attached or detached in an instant without requiring any special tools for the purpose.

The invention has among its further objects the production of a device of the kind described that is simple, convenient, durable, efficient, and satisfactory, that is economical in price, as well as economical in use.

To this end my invention consists in the novel construction, arrangement and combination of parts herein shown and described, and more particularly pointed out in the claim.

In the drawings, wherein like reference characters indicate like or corresponding parts, Figure 1 isa side elevation of a portion Of a spindle and brush carried thereby; Fig. 2 is substantially a sectional view on line 2, 2 of Fig. l; Fig. 3 is a perspective view of the lower end of the spindle; Fig. 4 is 'a perspective view of a cooperating brush part; Fig. 5 is a perspective view of a portion of the end of the brush.

Referring to the drawings, and particularly Figs. 1 to 5, 1 represents a suitable brush, or rather the bristles part of the brush, which are secured to a shank 2, ar-

serial no. soaosaj ranged to be carried by aspindle 8 ofthe washing machine. It may be mentioned that while in the drawings the spindles are shown with the brushes apparently on the lower ends thereof, in operation it is iinmaterial whether the brush is at the upper end of a spindle, which spindle is supported v from below, or at the lower end of a spindle carried from its upper end. Usually, however, the spindle is suitably carried by the washing machine at its lower' end, and the brushes arranged upon theupper ends of the various spindles, or oppositeto the ar'- rangement shown in the drawings. In the brush construction shown, the shank 2 is of twisted wire and formed with the ends 4, 4

preferably extending 4transversely to the shank, so as to detachably engage the spindle. As shown, the spindle is preferably tubular and slotted lengthwise as 'at 5, 5, and transversely as at 6, and preferably notched as at 7. The slots 5, 5 are of a size to admit the ends 4, 4 of the shank 2, the brush being positioned by a longitudinal or lengthwise movement of the shank, and then turned so as to engage the ends `4, 4 in the notches 7, 7 The brush is maintained in position by a spring 8, or its equivalent, which preferably bears against In order to center the shank of the brush in the spindle, I preferably provide a member l0, which may be flanged at 1l, and is slotted as at 12, the same having an opening 13 of suitable size, so that the member normally closely fits the shank of the brush. This member may be positioned on the brush with the ends'4, 4 projecting through the slots 12, 12, and the brush and member then positioned or inserted in the spindle. When so positioned the spring 8 bears upon the end of member l0, and firmly maintains the brush in position in the spindle. The spindle may be connected to the washing machine in any desired manner. Asshown, it is slotted as at 14, and formed as at 15, arranged to engage a suitable cooperating rotating part of the machine. The machine itself may be of any desired type and contain any desired number of spindles. With the device constructed substantially as shown, any brush may be inserted or removed in an instant without requiring any special tools. There is nothing to stick or bind as in a screw threaded construction for example. It will also be noted that the brush part, consisting of the bristles l and shank 2, when worn out, may be easily renewed or replaced, and with a minimum of cost, since only the worn-out parts are required t-o be replaced.

It will be noted that with the constructions shown, the brush may be snapped on or olf in an instants time. The matter of time saving in removing or replacing brushes is of no small importance when it is considered that a machine may have from 16 to 20 spindles, or more, usually arranged very close together, so that it is ordinarily difiicult to reach any with a wrench, screw driver or the like, to release the parts, particularly where the brushes are attached directly to the spindle by athreaded or similar engagement. Likewise with a threaded engagement of the brush and spindle it may oftentimes stick and bind, and it would be no uncommon occurrence to require ten to twenty minutes time to remove one brush. With my constructions all may be removed or replaced in a very short time. lVith the present construction, should the machine be accidentally reversed, as is sometimes the case, there would be no unscrewing or dropping out of the brushes. Of course where the brushes are at the top of the spindle there is no tendency for the brush to drop out. Another important feature is the economy in manufacture and use. With the device not only is time saved, but the brushes need not have a tip permanently secured thereto, and may be purchased without tips at a considerably lower price, and operate in exactly the same manner. This cost is not a small item when it is to be considered that with hard usage, for instance in a brewery, the life of a brush may be limited to a days use or less, and there may be in use from one to half a dozen or more machines, each provided with a plurality of spindles.

VHaving thus described my invention, it is obvious that various immaterial modifications may be made in the same without departing from the spirit'of my invention; hence I do not wish to be understood as limiting myself to the exact form, construction, arrangement or combination of parts herein shown and described, or uses men- What I claim as new and desire to secure by Letters Patent is A device of the kind described, comprising a tubular spindle, slotted lengthwise at one end for a portion of its length, and slotted circumferentially at the inner end of said lengthwise slots, and slightly slotted at the closed end of said second mentioned slots toward the said end of the spindle, a brush provided with a twisted wire shank formed with the ends of the wires projecting on opposite sides thereof, and of a length to engage the spindle in said last mentioned slots from the interior of the spindle, a bushing detachably arranged on said shank, comprising a tubular member' JOHN M.
