This inventionrelates to egg candling apparatus, and particularly to novel means whereby a; dark room may: be lighted-intermittently for the: purpose of displaying crates ofi eggs, or their contents, and whereby the lighting apparatus may be operated to: interrupt; the passage -of light tothe dark room while eggs selected from the cratesare being candled, novel means being provided for operating the light" controlling means and the candling mask, the said in- Y vention including novel means whereby the light shutter and the candling mask are operated in unison.

It is a further object of this invention to provide a candling apparatus which can be expeditiously manipulated for the purposes intended and which has advantages in points of simplicity and efiiciency, the same being comparatively inexpensive to manufacture.

With the foregoing and other objects n view, the invention consists in the details of construction, and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, reference will be had to the accompanying drawings forming part of this application, wherein like characters denote corresponding parts in the several views, and in which- Figure 1 illustrates a view in elevation of an egg candler embodying the invention;

Figure 2 illustrates a sectional view on the line 22 of Fig. 1; and

V Figure 3 illustrates a view in elevation of the device with the parts in diflerent positions from that in which they appear in Fig. 1.

In these drawings 5 denotes a hollow bracket which may be suspended or supported in any appropriate way, and the bracket terminates in a hood or casing 6. It is intended that electric conductors shall be extended through the bracket to the interior of the casing where electric lamps may be employed for lighting the interior of the hood, although, of course, under certain conditions, other illuminating means may be supplied within the hood. The lower end of the hood or casing is provided with a door or shutter 7 having one of its edges hinged, as at 8, to the hood in order that the said shutter may swing down- 1927. senar No. 204,815.

wardly and "upwardly, as h indicated by the arrow in Figml.

A bracket 9 extends from the hood or casingf'and a bearing 10 is formed on its outer end, the said bearing constituting a support for a pin or shaft 11 which may rotatein the bearinguAn alrm.12 carries oris attached to. thepin or shaft 11 andthe end of the arm remote from the bearing is provided with a connection 13 which is attached to the shutter ,.as1shown in Fig. 2,

so that asthe arm oscillates, the shutter is moved to a closed or open position, according to the direction of movement of the arm.

The arm is provided with an angularly disposed extension 14 to which a flexible or other element 15 is attached and this element 15 is connected to an arm 16 of a mask 17 which is oscillatably mounted on a pivot 18 on the side of the casing. The mask is shown as having apertures such as 19 to which eggs may be applied during the candling process, and the apertures of the mask are in alinement with an aperture 20 in the casing so that light in the casing may be observed through the apertures of the mask and the aperture 20 of the casing.

From an inspection of the drawing and the foregoing description, it will be apparent that in operation, the room in which the candler is installed and which may contain eggs in crates or containers, may be provided with light when the shutter 7 is opened in order that the contents of the container may be observed, and that when eggs are selected from the containers which are to be candled, they will be applied to the apertures of the mask and pressure exerted on the mask to move the mask into position concentric with the external surface of the casing, which movement will impart movement to the shutter through the arm and its connection so that light will not issue from the bottom of the casing. When this condition exists, there will be no light in the room, and hence, eggs which are applied to the apertures of the mask may be observed and, of course, if they are unimpaired, the light that is within the casing may be distinctly observed, whereas if the eggs are not fresh, the light would be obscured or obstructed, so that by this means, the operator during the candling process may be provided with intermittent illumination in the room and it will be intermittently interrupted in order that it will not interfere with the candling operation.

I claim:

1. In a candling device, a casing adapted to have a source of light, the said casing having an openin in its wall, a shutter hinged to the casing at its lower end for opening and closin the said casing, an apertured mask movab mounted with relation to the aperture of t e casing and adapted to guard and ungniard the aperture, and means for communicating the motion of the mask to the shutter.

2. In a candling device, a casing adapted to have a source of light, the said casing having an opening in its wall, a shutter hinged to the casing at its lower end for opening and closing the said casing, an apertured mask movably mounted with relation to the aperture of the casing and adapted to guard and unguard the aperture, an arm on the said mask, an arm pivotally mounted with relation to the shutter, means for connecting the second mentioned arm to the 25 shutter, and means for communicating the motion of the first mentioned arm to the second mentioned arm.

3; In a candlin device, a casing ada ted to have a source 0 light and having a s ut- 30 ter for opening and closing the casing, a device through which light may be admitted to eggs being candied, and means for impartlng the motion of said means to the prevent light from emanating from the casing, an illuminating means associated 40 with the casing, and means for imparting motion of the egg illuminating means to the means for closing the opening in the casing. 1 1
