@My invention relatesto. farm implementsand -mreiparticularly ,to a device for cleaning .eggs. I'Ihelobject of my invention is toprovide, an` egg cleaner adapted to be attached; Ito v -a, ltable Etop orAtheLlike and to support an egg Whilegit is being :cleaned by a belt of slightly abrasivelquality driven by a motor.

:Anotherobject oijmy invention is to provide an egg cleaner of the character indicated above equipped with a springzbiased push rod having -a,;leather disk at its endadaptedto prevent the vgg from slipping out of the operators handLwhile it is moved over the abrasive belt.

A further object of myy invention is to provide an .eggcleaner of the character indicatedfabove adapted `to clean .eggs without wetting'them, wherebyspoilage of eggs caused! by wettinggthem, ris.prevented. r':

'.1 1 Other objects of my invention not specifically mentioned may appear in the' following specii'lca- L vtion rdescribing my inventionl with reference to fth'e accompanying drawing illustrating a prefferredembodiment ofmyH-invention. It is,how ever, to be understood, that my invention is not to be limited or restricted to the exact construction and combination of parts described in the specification and shown in the drawing, but that such changes and modifications may be made which fall within the scope of the claims appended hereto.

In the several figures of the drawing, similar parts are designated by similar reference characters, and

The egg cleaner forming the subject matter of my invention comprises a frame F formed by two brackets B. Each bracket has a plate-like vertically arranged body I0, and on the upper edge of the front end portion of each body a "s olaims. (c1. 51 1 35) laterally extending f 1ange Il is formed. A cen- :trallylocated s lot I2 extends from the front edge oheachrlange rearwardlyinto said flange for a purpose to be described later. Adjacent the rear 4end of `each,flange II, a shallow downwardly extending notch vI3 isprovided in the upper edge of vaelachbody 10 and the upper, edge., portion M of jv each body Alocatedrearw ardly of said notchwis arranged at a somewhat l higherv level than Y the tpnsurfaceof .thefflarlge Il. ,At a dstanbelow therear edgeportion I4 and infront ,of the rear bodies and acrownpulley Il is rotatably mounted i @en said laxlewhich is providedlon eachfo'f its 4 endportions-with a nut I8 to secure it in positi on, An elongated block vI 9 is located between the two bodies I0 somewhat in frontof the front suriace portion `ofthe crown pulley Il, so that theupper edges of; s aid block project a little above theupper edges` of the two bodies. The upper surface of thelolockvv IS is concaved transverselyas .,indicatedat2D- andislinedwith a ylayer of felt 2I'g l ued or otherwise secured onto said 'blok. .Qn each e nd}of the b1ock an end plate 22 is se- ,.cured protecting 'the 'ends of thevfelt layer. An idlerfpul1`ey23 is rotatably mounted on a second axle 124v extending vthrough the two plate-like bodieslgjustrearwardly of the notch I3' a nd somewhat below the top rear edge I4 of "each body.

Two countersunk bolts 25 or the like extend through a table top 26 or the like and project beyond the lower surface thereof. These bolts are located at an equal distance from the rear edge of the table top and at such a distance from each other, that they are adapted to enter slidably into the slots I2 of the brackets B, after these brackets are connected with each other by means of the block I9 secured to and located between the bodies I0. A knurled nut 21 or the like mounted on each bolt 25 secures the assembled frame F to the under surface of the table top.

A motor 28 is mounted in any desired conventional manner under the table top, so that a rubber pulley 29 rigidly mounted on the motor shaft 30 is in alignment with the idler pulley 23 and the crown pulley I1. A slightly abrasive belt 3| is trained over the three pulleys and extends over the concaved surface of the block I9. The tautness of the belt is adapted to be regulated by positioning the brackets IIJ relative to the motor 28 by means of sliding the brackets into the desired position and securing them in this position by tightening the nuts 21.

A U-shaped guide 4bracket 32' is secured to the top surface of the table top 2B by means of screws 33, extending through the web of the guide bracket into the table top. A push rod 34 extends slidably through the flanges of the guide bracket at a distance above the table top 26. A stop pin 35 extends diametrically through said push rod adjacent the inner surface of the rear langeA of the guide bra-cket and the push rod projectsA rearwardly beyond this guide bracket flange and part Way over the block |19. A light helical spring '36 surrounds the push rod between the front flange of the guide rod and the stop pin and urges the push rod into its rear most position. A leatherv Y diskv 31 is secured to the rear end of the push rod. When eggs are to be cleaned, the motor 28 is started and an egg 38 is held lightly against the 1 portion of the moving belt 3| traveling over the concaved block I9, and is turned lengthwise and crosswise so that said belt touches all portions of the egg and cleans it. The concave feltA lined surface of the block I9 serves to support the belt and to curve into a shape adapted to surround a -comparatively large part of the egg to'expedite the cleaning process. The belt 3| travels forwardly over the block IS urging the loosely held vegg against the leather disk 31 on the spring biased .push rod 34 so that the egg cannot slip out ofthe hand of the operator under the light urge of the cleaning belt. The belt is prevented from slip` ping since it is trained over the motor pulley 29 which is made from rubber.

I claim: l 1. An egg cleaner comprising a table, a motor therebeneath and including a shaft and pulley mounted thereon, a pair of long plates disposed with their side faces vertical and 4in horizontally spaced parallel relation with two adjacent ends beneath the table, means securing said ends beneath the table, said pulley being inline with the space between the plates, the plates having adjacent top edge portions lying in a horizontal plane closely approaching the plane of the table top,` a pulley rotatably mounted on'a horizontal axis between the other two adjacent ends of the plates, a cleaning belt encircling'said pulleys and having the top run thereof passing between the plates, a belt'supporting and shaping block secured between the plates between the said topy edge portions thereof and having a transversely conceived top surface` in which the top run of the belt ts and slides, and means supported on the table top and extending longitudinally of and above the; top surface of the spacing block for facilitating manual maintenance of an egg in position on the block supported portion of the belt.

yf 2.L An egg vcleaner of the character described 'in' clair'nr 1, ln which the said means securing said ends of the plates beneath the table comprises oppositely directed lateral anges carried by the plates adjacent to the first mentioned two vadjacent ends and disposed against the underside of the table top, each of said ilanges having a long "slot therein extending longitudinally of the plates and a securing bolt engaging in each of the slots and connected to said table, said slotted flanges and bolts facilitating the tensioning of the belt by movement of the plates longitudinally.

-3. An egg cleaner of the character stated in claim' 1, with a felt liner within the said concaved Vtop ofthe block and protecting plates'for the ends of said liner secured to the ends of the block and projecting above the concaved surface of theblock to the level of the top of the liner, said belt sliding across the top edges of said protector plates. l
