T0. all whom t ,may concern:

Be it known thatI, ALBERT W. ENGEL, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois', have invented certain new and useful Improvements in Brushes, of which the following is a specification, reference being had to the accompanying drawings, forminga part thereof. l,

The purpose of` this invention is to provide an improved construction for brushes, and in certain features it is designed especially for l brushes used in bottle-washingand which are `rotated and supplied with water through a l by which` it is driven.

hollow shaft to which the brush is detachably connected, and these `features of` my invention have thefspecific purposelofl rendering the brush proper-#that is', the stem and bristles or equivalent elements-readily disengageable from the device by which it is connected to the shaft, so that worn-out brushes may be discarded and replaced by new ones with .minimum expense.

`It consists in the features of construction which are set out in the claims.

In the drawings, Figure 1., is side elevation of my improved brush and portion of the shaft p Fig. 2 is a section at the line 2 2 on Fig. 1. Fig. 3 is a section at the line 3 3 on Fig. 2. Fig. 4 is a section similar to Fig. 2, showing a modified form. Fig. 5 is a detail section at the line 5 5 on Fig. 4. Fig., 6 is a section similar to Fig. 2, showing a fur-` v ther modification in the structure.

Fig. 7 is a section at the line 7 7 on Fig.` 6. Fig. 8 is a sectional viewsimilar to Fig. 2, showing another modification. Fig. 9 is a section at the line 9 9 on Fig. 8.` Fig. 10 is an elevation of a hand-brush embodying some of the principles of myinvention. of a blank which `is ,employed formforming a clasp to deflect thebristles to one side.` =Fig.

12 is a view of another somewhat similar. clasp, same being shown folded as when clasp- Fig. 11 is a plan view tated. 3 is a sleeve which is screwed onto the threaded end of the hollow shaft 2 and serves to attach the brush to the shaft. 4 is the stem of the brush, `which is made of twisted wire, having bristles involved in the twist of the wire in a manner which is well understood and need not be specifically illustrated or described. 5 5 are two wings or oppositelyprojecting portions of the bristles. 6 represents an axially-protruding bunch' of bristles. The wire forming the stem 4 is folded upon itself preparatory to being twisted to involve the bristles and forms atthe fold an eye 7, which is preferably` oblong, fas illustrated. The sleeve 3 has near the base or end at which it is attached to the shaft 2 oppositely-situated ob ng apertures 8 8, through which a key..r lmay be inserted, taking through the eye 7 of the stem. The position of the key when thus inserted is such that the end of the shaft 2 when screwed into the sleeveI may encounter the key, and by being screwed farther in after such encounter the shaft binds the key tightly in place and causes it to retain the stem of the brush and constitute by its `engagement with the eye of the latter the means of transmitting rotary motion to the brush. To render this result more certain and the attachment of the brush by its stem to its sleeve more securelby preventing the escape of the key 9 even if the clamping-presslight recess or rabbet 10 at each end, forming shoulders 1l 1l, which enter between the opposite walls of the sleeve when the shaft is screwed against the key, thus locking the key in place.

In Figs. 4 and 5 I have shown a modification consisting in shaping the wire at the end of the stein 4 so that there shall be outwardlyj utting projections 12 12, which may take into the apertures 8 8, the wire yielding sufiiciently to permit the stem Withthese projections at the end to be introduced through the sleeve to the point at which the projections may engage the apertures,lthe elastic reaction of the wire being relied upon to effect the engagement. The end of the shaft screwed down against the eye or the projection is then relied upon to render the engage- ICO ythan in the other forms illustrated, and instead of providingr the apertures shown in the other forms a shoulder or seat 13 is left at the foot of the thread by which the sleeve is screwed onto the shaft, and channels 14 14 extend from that shoulder on opposite sides to the other end of the sleeve. The sleeve is `then indented to form slight projections 15 I5 for stops opposite each other and each ninety7 degrees around from the channels 14E. With this construction a stem having projections 12 12 may be entered with these projections following the channels 14 until the shoulder is reached, and then being turned to take the projections away from the channels, the sleeve being screwed onto the shaft, the latter will engage the projections and bind them on the shoulder, carrying them by friction, perhaps, around against the stops 15, formed by theindentations described, and the brush will be securely held in place, as in the other forms. The form shown in the principal figures has the advantage that the brush while securely retained is flexibly connected to the sleeve, the pin being loose in the eye 7, while being tight in the sleeve.

Another feature of my improved brush consists in a device for gathering the bristles in two fiat vanes instead of being left protruding in all directions, as when merely arranged first in a sheet between the two wires, and then engaged by the twisting of the wires, so that they protrude really-in a spiral, but a spiral so closely twisted that the effect is substantially a cylindrical brush. This device for gathering bristles into Hat vanes consists of a clip or clamping element 16, cut outof sheet metal with serpentine orserrated edges, the protruding teeth of which are at opposite edges out of line, so that when the device is folded into approximately cylindrical form each tooth juts toward a recess in the opposite edge. This clip is applied to the brush after it is otherwise formed by parting the bristlesat any longitudinal line and gathering them from the parting-line both ways toward the opposite side, applying the clip partly folded, as shown in Fig. 9, to complete the gathering of the bristles toward the side toward which they are being folded, and then further closing up the clip on the bristles and about the stem until it is securely held and securely holds the bristles gathered to one side, as seen in Fig. 1 Preferably two such clips are employed, each being used to gather the bristles along part only of the length of the brush, one part of the bristles being folded and held by the clip projecting from one side and the other part from the opposite side. The advantage of this construction of the brush is that thereby the bristles, massed together instead of protrudf ing in all directions, reinforce each other and make a stiffer and more effective brush and also afford better access for water, which when the brush is cylindrical, having the bristles projecting in all directions, nds its way obstructed at every point, whereas when the bristles project in a vane or blade at one side only at any particular part of the brush the remainder of the space is open for discharge of the water, while the rapid rotation of the device as thoroughly distributes it as if the brush were cylindrical. The offsetting of the two vanes of bristles so that each revolves in a different path not only balances the brush and makes it revolve more steadily, but also fnrthers t-he distribution of the water to all parts. This method of gathering the bristles to one side after they have been secured in the stem by twisting the wire so as to make a cylindrical brush may be ernployed in brushes of other forms and with the bristles gathered toward one side throughout the entire length. In Fig. 10 I have shown a hand-brush of this form, the clip 17, used for gathering and securing the bristles to one side and holding them securely, being extended to embrace the entire body of' the bristles.

I claimi l. In a bottle-washing brush in combination with a hollow shaft for rotating and supplying water to the brush a sleeve interiorly threaded at one end for screwing it onto the shaft, the brush having its stem adapted to be inserted in the sleeve from the other end; a means for engaging the stem with the sleeve to prevent its withdrawal, said means being encountered and bound in place by the end of the shaft when the sleeve is screwed onto the latter.

2. In a bottle-washing brush in combination with a hollow shaft for rotating and supplying water to the brush a sleeve interiorly threaded at one end for screwing onto the shaft, the brush having its stem adapted to be inserted into the sleeve from the other end and having an eye in the inserted end, the sleeve having apertures with which the eye may be alined transversely; a key inserted through the apertures and the eye and bound in position by the end of the shaft when the latter is screwed into the sleeve.

3. In a bottle-washing brush in combination with a hollow shaft for rotating and supplying water to the brush a sleeve interiorly threaded at one end for screwing onto the shaft, the brush having its stem adapted to be inserted into the sleeve through the other end and having an eye in the inserted end, the sleeve having apertures with which the eye may be alined transversely 5 a key inserted through the apertures and the eye, such key being recessed at the edge toward the brush for engagement with the edges of the apertures in the sleeve, the shaft when screwed IOO IIO

Ant' y'the sleeve reaching the key and forcing it into suchengagement.

4:. A brush comprising a stem and bristles engagedtherewith and protruding transaxially therefrom and a-clip having serpentine or serrated lateral edges folded about the stem and gathering the bristles from both directions toward one side of the stem to form them into a radial vane or sectoral body.

5. A brush comprising a combination -with a stem and bristles engaged therewith, and protruding therefrom clips for gathering the bristles into radial vanes of sectoral bodies, one clip being secured about the stem to form such radial or sectoral body,of bristles extend-I ing part of the length of the stem in one direction therefrom, the other clip being similarly applied to gather the bristles on a dif- `ferent portion of the length to the opposite Fside.

i 6. In a brush a clip for gathering and re' `lstraining the bristles toward one side, having opposite lateral edges indented forming progjecting teeth alternating with recesses, the `teeth at each edge being arranged to project toward the recesses at the opposite edge when u the clip is folded to clasp the brush.

In testimony whereof I have hereunto set my hand, at Chicago, Illinois, in the presence of two witnesses,.this 26th day of August, A. D. 1901. 4
