P. T. EDGAR BOTTLE CLEANING BRUSH 2' Sheets-Sheet 2 Filed April 9, 1931 Patented Oct. 13, 193i UNITED STATES PAUL 'r. EDGAR, or ABCOI-A, 'nmmo'xs BOTTLE CLEANING BRUSH Application filed April 9, 1931. :ise'rial 10.188392.

, This invention relates to improvements in brushes, and the primary object of this invention is to provide a brush especially adapted for cleaning the interior of a milk bottle or like receptacle.

A still further object of the invention is to provide an expansible brush that is normally collapsed, and which in a collapsed condition is inserted in the milk bottle, and may be subsequently expanded for forcing the bristles of the brush into engagement with the inner face of the bottle to facilitate cleaning the same when the brush is rotated.

, Other objects and advantages of the invention will become apparent from a study of the following description, taken in connection with the accompanying drawings wherein:

' Figure 1 is a side elevational view of the brush embodying the features of the present invention, the same being inserted in a milk bottle and shown in an expanded position for engagement with the inner face of the bottle.

Figure 2 is a side elevational view of the brush per se, the same being in a collapsed or retracted position.

Figure 3 is a transverse sectional view taken substantially on the line 3-3 of Figure 1.

Figure 4 is a similar view taken substantially on the line 4-4 of Figure 2.

Figure 5 is a bottom plan view of the brush.

Figure 6 is a perspective view of a U- 35 shaped clamping element forming a part of the present invention.

With reference more in detail to the drawings, it will be seen that 5 designates a sub stantially inverted U-shaped rectangular frame preferably formed of two strands of wire twisted one about the other and providing for the frame a crown or connecting portion 6, parallel side portions 7 with the latter portions 7 at their free ends provided with bent portions 8 disposed inwardly of the frame and laterally of each other as shown in Figures 1 to 3 inclusive, and preferably with the bent portions 8 terminating in upwardly extending terminals. Thus the mem- 50 bers 7 provide substantially the L-shaped legs for the'frame andare connectedatztheir. .upper ends by the .bight or bridge-portionfi. The bristles of the brush unit Qaresecured in the twist of. the leg. members. in thensual and well known manner. The brush-units extend from. substantially the topsofthe leg, members '7 to the ends of the .term-inalszofthe lowerbent portions .8.

The wiresfforming the frameorbrush-core 5 at the 'bight or. bridge .6. haveaadgiacent por- 1 00 tions bent outwardly from one another. to provide therebet ween suitable guide means for an operating bar 10 :that extends centrallyand'longitudinally of the frame'asslgges'ted in Figures .1 and. 2.

Longitudinally spacedg pairsr'of oppositely disposed arms 11 are pivoted at their respective inner .endsto .the bar 10 as. at .12, rand U-shape'd .members13 are pivotallyxsecured to the outer ends of the armasiat. 14: andfixedly embrace adjacentportions oftthe side or leg members '7. a a

."For' the .upper. end of the actuatingban-IO there isprovided'a suitable handle-l5.

The resiliency ofthewireframe .or core .5 has a tendency to normally :maintain the parts in the position ashown in'IFigure .2, whereby the brush units 9..will..loe disposed closely together, and when in this position, the brush is readily inserted downwardly into a'bottle 'B -such:as1a milk bottle and when the end portions 8 of the legs or sides 7 engage the bottom of the bottle, a downward pressure upon the handle 15 will cause the actuating bar 10 to move downwardly relative to the frame 5 causing the arms 11 to be forced outwardly, and as a result, the legs or sides 7 of the brush will be brought into engagement with the inner Wall of the bottle and at the same time, the bottom of the brush will be extended to entirely engage with the inner face of the bottle bottom as shown in Figure 1.

It will be also noted that during the ex pansion of the frame or core 5, the upper portion of the latter is drawn into the bottle by the flexing of the upper portion of the leg or side members 7 against the sides of the bottle 'to conform to the shape of the inclined inner surfaces of the sloping shoulders of the bottle.

(See Figure 1).

'By holding the handle 15in its lowered po- I sition, and by turning the same, with the arts in the position shownin Figure 1, it will be apparent that the interior of the bottle along thesides and at the bottom thereof can be thoroughly cleansed in a very short period of time.

By pulling upwardly on the handle'15, the I sides or 'legs'7 willbe moved to the position shown in Figure 2 and the frame or core 5 willassume its original shape whereuponit may be withdrawn through the neck of the bottle.

vention, it 'isto be understood that the same is susceptible of changes, modifications and improvements coming scope of the appended; claim'.. y

Having thus described my'invention, what I claim as new is:

connected at their upper ends by a A-bottle cleaning-brush comprising an inverted substantially U-shaped frame formed of spring wire and consisting of a pair of spaced oppositely disposed L-shaped leg membridge portion and having a respectivelower bent-portion disposed inwardly of the frame and laterally'of each other, an operating bar extending centrally and longitudinally of I "the frame with its upper end disposed slidablythrough the bridge portion of the frame, longitudinally spaced pairs of oppositely disposed arms pivoted at their respective inner ends to said bar for relatively opening andclosing movement inwardly of the frame,

U-shaped members pivotall secured to the outerends of said armsand xedly embracing adjacent portions of said leg. members, said frame being'tensioned to normally hold the legmembers close together, and the said arms in relatively closed relation, said' bar being i shift-able; relative to the frame for opening the said arms and separating the said leg members. v r In testimony whereof I aflix my signature.

I PAUL T. EDGAR.
