EGG-TESTER.

Specification of Letters Patent.

Patented Mar. 29, 1921.

Application filed December 8, 1919. Serial No. 343,199.

fl yo all 107mm 'it may concern.'

lle it known that I, WM/ran ll. Tuivsrinn, a citizen of the United States, residing at Gordonsville, in the county of Logan and State of lentuclry, have invented a new and useful Egg-Tester, of which the following is a specification rThis invention relates to improvements in testing devices, and it is the primary object of the invention to provide a device of this character' having novel means to permit the same to be operated in the daylight.

A further object of the invention is to provide electrical means in circuit with an electric lamp for supplying1 the light to the device, the electrical means being controlled automatically by the application. of an to the egg supporting table, forming a part of the device.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawing1 Figure 1 illustrates a longitudinal sec` tional view of an egg tester constructed in accordance with the present invention;

Fig. 2 illustrates a diagrammatical view of the electric circuit, forming a part of the invention Fig. 3 illustrates a plan view partly in section showing the egg supporting table,

together with the means for supporting the same; and

Fig. 4: illustrates a side elevational view of the egg tester, the hood 'thereof being shown as moved to its inoperative position.

Referring to the drawings in detail, the device .is shown as including a body portion 5, and a hood section G hingedly connected to the body portion 5 by means of the hinges 7. y

This body portion comprises side walls 8, a bottom wall 9 and an end wall 10, the upper wall thereof being indicated at 11 and including a hinged section 12 connected to the portion 11 through the medium of the hinges 13, whereby the hinged section l? may be moved to open the body portion to permit of easy access to the interior thereof.

A partitioningr wall 14 divides the interior of the body portion 5, substantially intermediate the length thereof, to provide a lamp compartment v15 and a battery compartment 1G, the battery being shown as at 17, and supported by bracket members 18, the battery 17 being Vin circuit with the lamp 19 through the wires V2O and 21, and through the switch member 20', the lamp 19 being supported by the` partition 111 at an angle with relation thereto, so that the light rays from the lamp 19 will be directed to a point directly in line with the opening 28 fornfied in the egg supporting table 23.

lt might be found practical. to connect the device with auxiliary batteries, such as the batteries of a telephone, and to this end the connecting posts 21 are provided, the same being supported on the body of the tester, and in circuit with the lamp 19.

This egg supporting table 23 closes the forward end of the lamp compartment 15, the screws 24k passing through the side walls of the body portion, the ends thereof being positioned within the supporting table i3 to permit the table to hinge iiujiwardly to open the lamp compartment 15 in the event that it becomes necessary to replace the lamp 19, or make other repairs to the interior thereof.

A relatively large opening 25 is provided in the table 23, which opening aceommodates the pivoted switch actuating member 26, which is hinged adjacent its lower end as at 2T, the hinge being of the type which will normally hold the upper end of the switch actuating member in spaced relation with the walls of the opening 25 for pur poses to be hereinafter more fully described.

Formed substantially centrally of the switch actuating member 26, is the circular opening 28, which is olf a diameter less than the diameter of the usual egg, to be tested by the device, the opening 28 being padded by the felt 29, which has its ends inturned to conform to the curvature of the walls of the opening' 28, so that an egg inserted in the opening will contact with only the padding material thus eliminating any possibility of breaking an egg while in the act oftesting the same.

Switch members 3() and 31 are secured to the egg supporting table 23 by means of the bolts 32, the nuts 33 operating on the ends ot the bolts 32 acting as means for securing the terminals 34 of the wires forming a part ot the circuit, to the switch members 3() and 31, the switch members being shown as eX- tending across the upper end of the opening 25, the ends et the

switch members

30 and 31 overlying each other, the material oi' which the

switch members

30 and 31 are formed having certain flexible qualities which will permit the same to normally lie in spaced relation with each other.

An adjusting screw 35 is disposed in the upper extremity of the switch actuating member 26, one extremity ot said screw 35 extending beyond the plane of the rear wall of the switch actuating member, so that the same will, when the switch actuating member is moved to a predetermined position, cause the

switch members

30 and 31 to be moved into engagement with each other to complete 4an electrical circuit through the

wires

20 and 21, with the result that the lamp 19 is lighted, the rays from said lamp being directed through the opening 2S of the switch actuating member 26.

It follows that an egg positioned in the opening 2S lies between the light rays ot the lamp 19 and the eye of the operator, so that the egg is made practically transparent; la person operating the device may readily determine the condition of the egg under operation.

K In order that the device may be etliciently employed tor testing eggs, in the daylight, l have provided a hood 6 which includes a main portion 36 and a right angled tapering portion 37, the same being box-like in formation and hingedly connected to the body 5, as before stated so that the same may be moved to its inoperative position, when not in use, but when in use the device is moved to a position as indicated by Fig. 1 of the drawings, in which position the tapering portion 37 is in a line with the lightrays from the lamp 19 to permit the operator to readily observe an egg supported by theegg supporting table 23.

Supported on the lower extremity of the hood 6, is a cloth-like attachment 38 provided with a hand opening 39 so that the opera-tor may insert an egg through the opening 39, the walls of said opening closely engaging the wrist or" the operator to exclude light from the 'interior of the hood 6, thus giving the operator the full advantage of the light rays of the lamp 19.

To further insure against light enteringthe hood 6, while in operation, a removable eye shade 40 is provided, which shade einbodies the arms L l1 secured to the base l2 of the shade, the arms l1 being supported in such relation with each other, that the same will closely engage the inner side walls of the hood G. whereupon the shade 40 is secured against displacement.

From the foregoing it is obvious that in operation it is only necessary tor the operator to insert an egg through the opening 21,9 ot the attachment 38, that is, when the device is used in daylight, whereupon the is positioned within the opening 2S ot the switch actuating member 2G. vIt Vfollows that slight pressure on the egg causes the switch actuating member to move` bringing the adjusting screw 35 into contact with one of the switch members 30 3l. with the result that the switch members 30 31 are moved into engagement with each other, to coinplete the electrical circuit, and cause the lighting of the lamp 19.

It is of course obvious that when the device is used in a darkened room, the hood 6 may be dispensed with, the tester being used in a position as indicated by Fig. Al ot the drawings.

Having thus described the invention, what is claimed is:

n an egg tester, a body portion, a partition dividing the body portion into a lamp compartment, and a battery compartment` the lamp compartment having` inclined .torward walls, a hinged egg supporting table iaving `a central opening and carrying a switch member. a switch actuating member adapted to Close the opening in the egg supporting table, said switch actuating member having an egg receiving openingand carrying an adjusting' screw providing a switch member to complete a circuit, a lamp in the lamp compartment controlled by the switch. a hood section pivotally connected to one end of the body portion, an eye shade disposed in one end of the hood. and said switch adapted to be actuated by an egg placed in the egg opening.

In testimony that I claim the foregoing as my own, I have hereto atlixed my signature in the presence of two 'itnesses TALTER E. TUNSTILL.
