EGG-WASHER.

Specification of Letters Patent. 7 Patented Sept; 192(1 Application filed March 27, 1920. Serial No. 369,405.

To all whom it may concern Improvements in- Egg-VVashers, of which Be it known that I, GUILronD' MoCRAY, a citizen of the United States, residin in Tomales, in the county of Marin and tate'of California, have invented new and useful the following is'a specification.

This invention relates to an egg washerv which is designed to enable eggs to be washed quickly and easily so as to render the samemore salable and also more appe tizing. a i

It is the object of this invention to produce a machine of this character which will permit of thoroughly. cleaning any dirt which may be on the eggs by the use of comparatively little efiort and power and enable this to be accomplished without materially. increasing the cost of the eggs.

4 In the'accompanyi ng drawings:

Figure 1 is a top plan view ofone form of machine embodying my invention. Fig. 2 is a fragmentary vertical section of the same taken on line 22, Fig. 1. Fig. 3 is a horizontal section taken on line 3-3, Fig. 4. Fig. 4 is a fragmentary vertical section, on an enlarged scale, taken on line' H, Fig. l.

Similar characters of reference refer to like parts throughout the several views.

Although this machine may be organized in various ways so as to permit one or more operators to, work at'the same time, thatshown in the drawings is so constructed as to permit two operators to work on oppo-' site sides of the table and each operator" is capable of cleaning two eggs at a time, so

as to utilize both hands to-the best advanout of engagement with the cleaning 'orwashing devices which are arranged below thetable top. Theupper side of the table top is preferably covered with a sheet 14 of metal forthe purpose of protecting the same against undue wear 'and' also enable the same to be cleaned more easily.

-Below each'of the openings 12 in the table top is arranged one of the washing or cleaning devices or units, which is constructed in accordance with my invention, and as the several cleaning or washing devices are alike in construction and operation, the following description of onejof them will applyto all of them:

15 represents a bowl or hollow head which is mounted to rotate about a vertical axis,

below. one of the openings 12 in the .table .top, which bowl-may be of any suitable shape but, as shown in Figs. 2 and/l, may

an-upright hollow shaft 19,'which is socured at its upper end to the outlet nipple 18 by means of acoupling sleeve 20 so that the .shaft is'axially in line with the axis of the bowl. This shaft is journaled in a pair of bearings 21 arranged one above the other and formed on a depending bracket 22 which is secured to the'underside of the adjacent part of the main frame 10. The downward motion of this shaft in these bearings is limited by engagement ofthe coupling sleeve 20 with the washer 23 resting on the upper one'of the bearings;21.

The shaft 19 is provided with a pulley 24; f

I 9Ov which is driven by a belt 25..

The companion bowls on the same side of the table are driven by the same belt 25' which passes' around the pulleys 24 associated with these bowls and also around a oneabove the'other and connected with a.

main driving pulley.27, this main driving pulley and-the two "intermediate driving pulleys 26 being mounted on a depending arbor 28 secureduto the underside of the main frame about midwaybetween the two pairs ofbowls.- I 1 if Although any suitable means may be em ployed for driving thev main pulley,,that shown in the'i drawing's is preferred and consists of an electric motor 29 mounted on the floor and providedwith a-driving pulley' 80, Y

and 'a' drivingfbelt 31 passing-around the pulleys 30 and 27 and-also around intermediate guide pulleys 32 which are mounted on themainrframe. I i a Across the upper end of each bowl is arranged a cleaning cloth 83 which is of coarse or open mesh, such for instance as ordinary burlap, which Wlll permit a cleaning fluid,

such as water or a mixture of water and grit or sand together with any. dirt removed from the eggs to pass from the inner or upper side of the washing cloth to the inner side of the bowl. In the preferred organization, this washing cloth is preferably mounted on the upper end of the bowl so as to form aidownwardly hanging sack or bag within the bowl as shown in Fig. 4. In order to permit of readily: renewing this washingcloth when the same becomes worn,

- means are provided for'detachably securing -the same to the bowl. A suitable means for fastening the wash cloth to the bowl is shown in Fig. 4 andthe same consists in providing the marginal portion or edge of the wash cloth with a downwardly projecting-flange or flap 34*which is clamped between an external screw thread v35 formed onthe upper edge of the bowl and an internal'screw threaded clamping ring 3,6 engaging with the outer side of this flap. In or- L= der to limit the downward motion of this clamping ring and increase the clamping effect of the same with reference to the cloth, the upper edge of'thi's ring is pro vided with an inwardly projecting annular flange 37 which engages with the wash cloth 7 above the upper edge of they bowl, as shown in Fig. 4. Y V

38 represents a. delivery pipe which is arranged below a table top and terminates at its outer end adjacentto the upper side of the bowl and washingcloth. The two delivery pipes 38 on the same side of the ma-,. chinepreferably form branches ofa main delivery pipef39 whichcontains a valve 40 v for controlling the'supply of cleansing mate-;

rial and these two'delivery pipes are in turn connected with the 'main supply pipe 41 which receivesits supply from any suitable source.- 3 1 I 7 Although any suitable'cleansing fluid may i be employed for this purpose, it is'prefere of soapi able to employ water towhich hasbeen added a suitable quantity of sand or other gritty} material and-also a suitable quantity At the lower end of each hollow shaft is arranged a valve 42 which permits of regulating the discharge of the waste cleansingliquid-0r materialfrom the bowl. IThe material discharged through the several hollow waste pipes 19 is caught by a pan 43 whichis supported on the underside of the table top and is provided in its bottom with V a waste pipe 44 leading to'the sewer orother place designed to receive the liquid which has been spent'in washing the eggs.

V 5 When the'machme'ls inoperation acleans i ing fluid is supplied by each of the'delivery pipes 38 into the upper end of each washing cloth, while thelatter together with its bowl and associated parts are rotating about a vertical axis. The eggs to be cleaned are taken one at a time by the operator and passed by one hand downwardly through the opening 12in the table top and engaged which not only aids in removing the dirt from the egg but also causes the dirt to be carried through the openings or mesh of the cloth and into the interior of the bowl from which latter the liquid escapes through.

the hollow shaft 19, valve 42, pan 43 and waste pipe 44 to the sewer.

By closing the valve42 more or less thees cape of the wash water. orliquid fromthe bowl can be regulated so as to maintain the level of the liquid in the bowl at such a height that the lowermost part of the cloth-- wash bag therein will be submerged in the cleansing liquid and thus facilitate the sof-y tening of the dirt on the eggs andpromote and expedite the cleaning of the same, this being particularly desirable when the eggs" are very dirty. e-

If city water pressure isv available the supply pipe 41. may bevconnected directly, therewith, but where such water supply is not available an overhead supply tank45 be provided, the bottom of which is connected withithe supply pipe 41 and thus causes'the cleansing water to flow by gravity from the tankto the several wash bowls, as shown in Fig. 2. 1 v f The machine is very simple in construction, it can be produced at comparatively low cost and Op rated with a minimum expenditure of power and effect its cleaning with a moderateamount ofj,water, and it.

permits of cleaning eggs easily, conveniently and ex editiously, so thata comparatively large number of eggs can be cleaned in a comparatively short time.
