EGG-CANDLING- APPARATUS.

Specification of Letters Patent.

Application filed April 15, 1911. Serial No. 621,410.

Patented Dec. 5, 1911.

To all whom it may concern:

Be it known that we, Enos MrroHELL and JOSEPH I-I. KEERAN, citizens of the United States of America, and residents of Osceola, Clarke county, Iowa,have invented a new and useful Egg- Candling Apparatus, of which the following is a specification.

The object of this invention is to provide improved means for receiving, holding and applying light to eggs in order to test said eggs as to their age and condition.

A further object of this invention is to provide improved means for receiving and testing eggs intended for table use and also to facilitate packing of the eggs for transportation and storage.

Our invention consists in the construction, arrangement and combination of elements hereinafter set forth, pointed out in our claims and illustrated by the accompanying drawing, in which- 1 Figure 1 is a front view showing the device in open position. Fig. 2 is a vertical section of the device at right angles to Fig. 1. Fig. 3 is a plan of the device in closed position.

In the construction of the device as shown a housing is provided which housing preferably embodies a rear wall 10, side walls 11, 12, a front wall 13 and a cover 14. The rear wall 10 and side walls 11, 12 preferably are formed with base flanges 15 provided with holes adapted to receive screws for attaching the housing in upright position to a suitable support such as a floor (not shown). The side walls 11, 12 are formed with vertical flanges 16 on their forward margins adapted to receive and slidingly engage hook flanges 17 on side margins of the front wall 13. The front wall 13 also may be provided with a base flange 18 adapted to come in contact with the support. It is the function of the base flange 18 to stiffen the lower portion of the front wall 13 and also provide means for engaging by a foot of the user to depress the front wall to the support. All of the walls of the housing preferably are formed with draft and ventilating ports 19.

The side walls 11, 12 are connected adjacent to the front wall .13 by cross-bars or stays 20. Angle bars 21 are fixed to the side walls 11, 12 adjacent to the upper margin of the front wall 13 and a transparent plate 22, preferably of glass, is mounted on said bars and extends across and forms a horizontal position within the housing. Angle bars 23 are fixed to the walls 10, 11, 12 of the housing above the plate 22 and a transparent plate 24, preferably of glass, is removably and replaceably and slidingly mounted on said bars. The plate 24 is spaced from the upper margins of the walls 10, 11, 12 sufli with a plurality of openings 27, preferably corresponding in number with the cells of the section25 ofthe egg-case-filler and registering therewith when the cover is closed.

It will be observed that the upper margin of the front wall 13 is below and spaced from the plate 22, but it may be made flush with said plate if desired.

It will be observed that ventilating ports 19 are provided between the plates 22, 24 in the walls 11, 12 supplementary to the open space in the front of the housing between said plates. Illuminating means, such as a lamp 28, are mounted within the housing. Any desired illuminating means may be employed.

In practical use of the device, after illuminating means is supplied to the housing a cell section 25 is mounted on the plate 24, the cover 14 is in open position, and eggs 29 are placed in the cells of the section 25 and rest on the plate 24. This can be done very rapidly by using both hands of the operator to lift the eggs from receptacles located on opposite sides of the housing, the operator facing the front wall of the housing. When the cell section 25 is filled with eggs the cover is closed, thus causing the illumination from the interior of the housing to be diffused through the eggs and enabling the operator to detect visually any defects, addling, staleness or incubation of the eggs by glancing at them rapidly and successively as they are revealed through the holes 27 Any egg below the standard of excellence adopted by the operator may be removed readily and conveniently from the cell section by opening the cover 14 and when all such have been removed and substituted by eggs of passing quality the operator opens the cover and removes the plate 24, cell section 25 and eggs thereon and deposits said cell section and the eggs therein in any desired place such as in a shipping case (not shown) by sliding the section and eggs off from the plate 24 to and upon a plate placed to receive them. The latter plate may be a table or horizontal partition of an egg-case-filler and in the event an eggcase-filler is used to receive the eggs, the egg-case containing the same should be of the side or end opening variety or type. Then the plate 24: is replaced and another cell section 25 is mounted thereon to receive a further supply of eggs to be tested.

Access is had to the interior of the housing by moving the front wall 13 vertically.

It is the function of the plate 22 to protect the plate 24 and eggs thereon from the heat of the illuminating means, and said plate 22 may be omitted when it is not needed for such purpose.

We claim as our invention- 1. An egg-candling apparatus, comprising a housing, illuminating means in said housing, a transparent horizontal partition in said housing, a cell section on said partition and adapted to receive eggs, and an apertured cover on said housing, the apertures of said cover registering with the cells of said section.

2. An egg-candling apparatus, comprising a housing, one wall of said housing being slidingly mounted, illuminating means in the lower portion of said housing, parallel transparent spaced plates in the upper portion of said housing, the uppermost plate adapted to receive a cell section and eggs therein, and an apertured cover on said housing, the apertures of said cover registering with the cells of said section.

3. An egg-candling apparatus, comprising rear and side walls, a front wall slidingly mounted on the side walls, angle bars on the rear and side walls, transparent plates mounted on said angle bars in spaced relations, a cell section mounted on the uppermost transparent plate and adapted to receive eggs, illuminating means beneath the lowermost transparent plate, and an apertured cover hinged to said rear wall and adapted to be closed upon said side Walls.

Signed by us at Osceola, Iowa, this 16th day of March, 1911.
