1 Claim.

This invention relates to an improved cleaning machine which is more particularly adapted for use for cleaning trays of the type used in hatcheries.

One object of the invention is to provide a cleaning machine employing wire brushes, said brushes having relatively long bristles or spines assuring the effective cleaning of the entire surface of an incubator tray or the like.

Another object of the invention is to provide a machine of this character wherein the brushes employed will reciprocate alternately with respect to each other with the result that a tray to be cleaned may be easily held against the brushes during the cleaning operation.

A further object of the invention is to provide a cleaning machine which is characterized by the utmost simplicity of construction.

Still further objects of the invention, not specifically mentioned hereinbefore, will become apparent during the course of the following description.

In the drawing:

Figure 1 is a side elevation of my improved cleaning machine,

Figure 2 is an end view of said machine,

Figure 3 is a detail perspective view showing the brushes as they would appear in engagement with a tray of the type employed in hatcheries, and

Figure 4 is a detail sectional view showing the connection between the crank shaft and the brush operating levers.

Referring now more particularly to the drawing, wherein like numerals of reference will be seen to designate like parts throughout the various views, the numeral I indicates in general the frame of my improved cleaning machine. The frame I includes corner posts or legs 2, preferably four in number, which are connected at their corresponding upper ends by side bars 3 and end bars 4. The frame I carries a base plate 5 which is horizontally disposed and is mounted near the corresponding lower ends of the corner posts, said base plate having its corners connected to said corner posts. Mounted on the base plate 5 is a motor 6, the purpose for which will be clearly explained hereinafter.

Extending across one end of the frame, between two of the e'nd corner posts 2, is a cross bar 1, said cross bar having connected thereto the corresponding lower ends of supporting

bars

8 and 9, the corresponding upper ends of said

bars

8 and 9 being connectedl to the side bars 3 As seen in Figure 1, the supporting

bars

8 and 9 extend substantially diagonally with respect to the frame I.

The side bars 8 and 9, near their corresponding mid portions, carry horizontally alined bearings I0, said bearings being held in place on the bars by U-bolts II. Extending transversely of the frame and having opposite ends journaled in the bearings Il] is a crank shaft I2, said crank shaft having cranks I3 and I4, each of which is provided with a journal I5. The crank shaft I2 carries a relatively large pulley I6 at one end, and said pulley is operatively connected with a relatively small pulley II on the motor 6 by means of a belt I8.

Medially of the lengths of the side bars 3 are mounted bearings I9, said bearings being held in place on the side bars by U-bolts 20. The bearings I9 support the opposite ends of a rock shaft 2|, said rock shaft, of course, extending transversely of the frame between the bars 3.

Mounted to rock on the rock shaft 2| are operating levers 22, said operating levers having enlarged mid portions defining bearings 23 which bearings receive the rock shaft 2I therethrough. The operating levers have bifurcated lower ends 24 which are connected with bearing sleeves 25, said bearing sleeves being formed on the corresponding outer ends of connecting rods 2S, said connecting rods each having split bearings 2'I which are operatively connected with the journals I5. Carried on the corresponding upper ends of the operating levers are brushes 28, each of said brushes having a base 29 and a plurality of relatively long wire bristles or spines 30.

In order to retain the levers 22 in proper spaced relation on the rock shaft 2|, I provide a spacer sleeve 3|.

'I'he operation of the invention will now be set forth. When it is desired to clean a tray of the type used in hatcheries, a tray of such nature being shown at 32, it is only necessary to start the motor 6, and hold the bottom of the tray against the bristles 30 of the brushes 28 for effectually cleaning said tray bottom. It should be understood that trays vary in size from twelve inches by thirty inches to thirteen inches by thirty-six inches. It should also be understood that my cleaning machine may be employed for cleaning trays of any size, shape or description. It is desired to point out that the crank shaft imparts alternate reciprocating movement to the operating levers so that the brushes will move alternately. The result of this will be that thorough cleaning will be assured without exerting excessive pulling strains on the tray, which strains would make said tray hard to hold. My cleaning machine is characterized by the utmost simplicity of construction and would be capable of use over a long period of time without repair.

Having thus described the invention, what is claimed as new is:

A cleaning machine including a frame having corner posts and side bars, supporting bars extending obliquely between certain of the corner posts and the side bars, a base plate, a motor on the base plate, a rock shaft extending between the side bars, a crank shaft extending between the supporting bars, operating levers shiftably mounted on the rock shaft, brushes on the operating levers, connecting rods operatively connecting the operating levers with the crank shaft, a pulley on the crank shaft, and a belt operatively connecting the pulley with the motor, the crank shaft being rotatable by the motor and being operative for imparting reciprocative movement to the operating levers for reciprocating the brushes for effecting a cleaning operation.
