and arei provided:through the. housings errd l walls IA andr l5"ioreapoommodatingtthe uides. The ameanstpmyided fon-movingstheeggsi along the track and cleansing the said eggs, consists in the providing or a pair of revolving spirally coiled cylindrical brushes, 36 and 3|, and mounting the said brushes on suitable shai'ts 3t and 35-, respectively, which shafts are revolvably supported in suitable bearings, 40 and 4|, respectiveiy, which are fixed in the end walls of the housing. The said spirally coiled brushes are positioned straddle the track 28 and in parallelism one with the other as shown to advantage in rigs. l, 2 and 4, whereby the eggs are caused to be moved along the track and thoroughly cleansed during the revolvable movement of the brushes. The outer end portions of the said brushes are preferably tapered as indicated at 36 and 57 to facilitate the admitting and releasing oi the eggs to and from the track 28. The said bearings 40 and 4| are retained in adjustable position by the cap screws 42 extending through the s ots 43, whereby the distance between the brushes can be varied in case of wear.

The means, provided for imparting revolvable movement to the brushes comprises a motor 44 connected to the said brushes in any suitable manner. The speed of the drive pulley 45 is reduced in any suitable manner to cause the brushes to revolve at the desired speed. The numeral 45 designates a housing enclosing a conventional reduction gear mechanism for reducing the speed of the drive shaft 41. Numerals 48 and 4e designate V-shaped pulleys fixed on the outer end portions of the brush shafts 38 and 39, respectively, for accommodating a V-belt 50, as shown to advantage in Figs. 3 and 6. A suitable fan 52 is fixed on the said drive shaft 41 for blowing air through the bottom 5|, of the tray 33, which bottom is preferably formed of a wire screen as illustrated in Figs. 1 and 6. The said motor and fan are supported on a suitable frame 53. A baffle plate 54 is preferably provided for deflecting air to the tray. The dryer fan 52 can be positioned in any desired location to properly dry the eggs in the most efiicient manner. For example, the said fan can be positioned between the gear reduction mechanism in the housing 46 and the motor 44, or the motor can be moved closer to the housing frame and the shaft of the motor extended and the fan positioned on the opposite end of the motor. be placed beneath thecleaner insteadv of below the dryer desired.

The side portions of the track 28 are grooved as indicated at 55 and 56 in Fig. 7 which grooves fit slidably on horizontal flange portions 51 and 58 provided on the track supporting members as shown to advantage in Fig. 2. The vertical flange portions of the track supporting members 29 and 30 are formed with vertically elongated holes 59 for receiving suitable bolts or screws 60, whereby the said supporting members 29 and 30 and track thereon are vertically adjustable. This adjustable feature enables the center of the egg or other object placed on the track to always be slightly below the center of the brush axis, thereby giving a slight downward thrust tothe egg being cleaned on the track and thus preventing the egg from coming out on top.

It will be seen to advantage in Fig. 3 that the brush members are revolved in the same direction and also to advantage in Fig. 4 that both of the brushes are spirally coiled in the same direction. The egg or other'objectpl'aced on the track between the brushes is thus pushed downwardly on one side by one brush and lifted upwardly on the This entire unit can opposite side by the other brush and at the same time conveyed longitudinally along the track. The egg is thus automatically revolved many times causing the entire surface thereof to come into contact with the revolving brushes in its course of travel through the machine. The brushes also keep the eggs aligned, enabling the eggs to travel straight throughout the entire length of the machine regardless of which end of the egg is inserted, thereby preventing the egg from turning end over end which would cause breakage and disturbance of the air cell. All sizes of eggs are readily cleaned. The brushes are self-cleaning, as centrifugal force removes any dirt or foreign substance from the brushes that have been removed from the eggs. An elongated resilient finger 6| extends through the opening 34 in the housing end member [4 and is secured to said member to lightly press the eggs downwardly on the track when starting the eggs through the brushes. Although the said brushes are spiraled in the same direction, the spirals can run in opposite directions if desired.

From the foregoing description taken in conjunction with the accompanying drawings, it will be obvious that when an egg is placed on the front guide 3| and is caught between the tapered end portions 36 and 31 of the revolving brushes as shown in Figs. 1 and 2, the spirally coiled brushes will push the egg along the track 28 to the outlet guide 32. During the movement of the eggs along the said track, water from the overhead pipe 22 will fall through the opening 24 to the eggs, whereby the revolving brushes will thoroughly cleanse the eggs. It will be noted that the said pipe is apertured for only a part of its full length, whereby the flow of water is stopped a short distance from the outlet guide 32, enabling the revolving brushes to wipe the eggs before they are released to the tray 33, where they are thoroughly dried by air blown from the fan 55 through the screened bottom of the tray. The eggs will automatically turn and roll through the said outlet guide 32 as shown to advantage in Fig. 2.

" ing eggs and the like, comprising a frame, a pair of elongated circular brush members revolvably supported thereon and arranged in parallelism and in proximity to each other, a track removably supported on the frame and positioned between the brush members and below the centers thereof for carrying the eggs, the said track being vertically adjustable for enabling eggs of different sizes to be carried in the correct height with respect to the centers of the brush members, means for guiding the eggs to the track, an apertured water supply pipe positioned above the track and in parallelism therewith for enabling water to fall on the eggs and brush members, the said brush members being formed with spirally coiled brushes that are spiraled in the same direction and means for revolving the brushes in" the same direction, whereby the eggs are revolved transversely on the track and moved longitudinally along the track simultaneously.

2. A device of the character described for washing eggs and the like, comprising a frame, a pair of elongated circular brushes revolvably supported thereon and arranged in parallelism and in proximity with each other, means for revolving the brushes, said brushes being revolved in the same direction, whereby the eggs are revolved, an elongated stationary track positioned between the brushes and below the horizontal centers thereof for carrying the eggs, means for guiding the eggs to the front end portions of the brushes, said front end portions of the brushes being tapered for receiving the eggs, the said brushes being spirally coiled in the same direction, whereby the eggs are moved along the stationary track, an apertured water supply pipe positioned above the track and in alignment therewith for providing water on the eggs and causing the eggs to be washed during their move- 6 ment along the track, a tray positioned at the rear end portion of the track for receiving the washed eggs and a fan revolved with the brushes for drying the washed eggs in the tray.
