To'all whom it may concern: 7 I

Be it known that I, GEORGE J OHNWHELAN, a citizen of the United States, residing-at Minneapolis, in the county of Hennepin and have invented certain new and useful Improvements in Egg-Washing Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has for its object to provide a machine by means of which eggs may be washed in large quantities and to this end it consists of the novel devices and combinations of devices hereinafter described and de- 'lined in the claims.

The improved washing machine is illustrated in the accompanying drawings, wherein like characters indicate like parts throughout the several views.

Referring to the drawings, Figure 1 is a plan view of the im roved machine. Fig. 2 is a side elevation o the machine,.'some parts being broken away and some parts sectioned. Fig. 3 is a transverse section taken on the line a m of Fig. 2. Fig. 4 is a detail in section taken through one of the screens 0r perforate decks on the line at w of Fig. 1; and Fig. 5 is a detail in section taken through one of the iicreens or perforate decks on the line a m of All parts of the machine are mounted on a frame-work 1 of suitable construction, from the upper portion of which a vibratory shoe or bottomless box 2 is sup orted, as shown, by means of yielding meta straps 3 secured at their upper ends to the upper portion of said frame, and at their lower ends to the lower front and rear portions of the said shoe 2. t its sides, the shoe 2 is' connected by it r 4 to crank disks 6 and 7 carried by a tr: erse crank shaft 8 mounted in suitable lH .igs in the frame 1. The crank disk 6 is in re form of a spur pinion that meshes with a spur gear 9 mounted on one side of the frame-work 1 and providedwith an operating crank 10, by means of which it may be rotated to-impart a vibratory movement to the shoe 2. As shown, supporting bars 11 extend transversely of the shoe 2 and are secured to the the bottom portion thereof, These mpporting bars 11 support a stack of separ le rectangular sieve frames 12, each of which is provided with a screen or perforate deck 13. These screens 13 constitute bottoms to the sieve frames 12, and at their front and rear portions they are curved upward, as best shown in Figs. 2 and 5, and are secured to the upper edge portions of the said frames. At

their side edges, the screens 13 underlie cleats 14 secured to the sides of the said frames 12, as best shown in Fi s. 1 and 4. i Secured to the frame 1, below the shoe 2 is a hopper'15 having an inclined bottom that terminates in a discharge spout 16. Overlying the shoe 2 and the bank of screens is a perforated spraying pipe 17 which, as shown, issupported at its ends by vertical projections 18 onthe frame 1. This spraying pipe 17 is preferably triangular in cross*sect1on,.as best shown in Fig. 3, and water is supplied thereto from a pipe 19 that leads from any suitable source'of su ly.

The eggs to be washed are'placed on the screens 13, as shown in Figs. 1 and 2, and water'is sprayedover the upper layer of eggs from the spraying pipe 17, while the shoe 2 is given vibrator l otion b rotation of the crank-equipped gear 9. be water will, of course, percolate through the several screens and come into contact with Under vibratory movements of the shoe and the screens, the eggs will be rolled back and forth and will continually change their relative positions with a slow and irregular rotary action, so that they are caused to grind against each other and against the screens, while at all times subject to the. spra of water, and under this action they wi e thoroughly cleaned. In fact, they will be not only thoroughly cleaned, but actually polished. The water dripping from the eggs will be caught by the hopper 15 and directed by the spout 16 into any suitable receptacle (not shown). The rollin or shifting movements of the eggs under t e vibratory movement of the shoe andscreens is due to the inclined upper and rear extremities of the screens which permit slight traveling movements of the layers of eggs on the screen and at the same time hold the eggs closely pressed to ether.

it will, of course be understood that any desired number of the egg supportin screens or erforate decks ma be em loye and it wil also be understoo that vibratory movements may be imparted to the screen supporting shoe, and that water ma be supplied to the eggs by any suitab e means.

all of the eggs.

\cagable of use for washing fruit and various er round, oblong or approximately round bodies.

What I claim is: '1, In a washing machine of the kind de- 1 scribed, a screen mounted 'for vibratory movements and provided with end or marginal portions that are gradual 1y upturned, the main'body portion of said screen being approximately smooth, flat and freeirom 15 structions, and the said screen being exposed. I

2, Ida washing Ina-chine of the kind described, a screen mounted ginal portions that are gradually upturned, the body of said screen being approximately smooth, flat and free from obstructions, in combination with a spraying device located above said screen, and the said screen being ex osed. V

J n testimony whereof I aifix my'ignature in presence of two witnesses.
