EGG 'rssrsn Filed Aug. 31, 1929 INVENTOR B HOWARD A PACKARD ATTORNEY Patented Sept. 30, 1930 UNITED STATES HOWARD A. PACKARD, or PIERCE COUNTY, WASHINGTON} Assrenon To VIACK'ARD' TESTERS, INCORPORATED, A CORPORATION or WASHINGTON EGG TESTER Application filed August 31, 1929. Serial No. 389,719.

This invention relates to improvements in egg testing devices and has reference in particular to devices employing an electrically lighted housing having an opening; against which the egg is placed for testing and which will be interiorly illuminated by the light from within the housing.

It is the principal object of the present invention to providea device that may be made quite small as compared with devices now generally in use, which may be easily handled, and'which is so constructed as to provide an interior dead air space'which prevents excessive heating of the device and renders it easily usable. I

Other objects of the invention reside in the various details of construction and in the combination of parts as will hereinafter be described.

In accomplishing these objects I have provided the improved details of construction, the preferred forms of which are illustrated in the accompanying drawings, wherein Fig. 1 is a View showing, in longitudinal section an egg tester embodying the present invention as connected through a transformer with an electric circuit.

Fig. 2 is a perspective view of the parts of the tester in disconnected relation.

Fig. 3 is a sectional detail lengthwise of the device.

Referring more in detail to the drawings:

The egg tester is designated in its entirety by reference numeral 1, and it haselectrical connection through wires 22' with a transformer 3, and this in turn has connection through wires 44 with an electric circuit; the transformer in this instance being employed to step down the current so as to permit use of a very small lamp with the ordinary 210-volt light circuit. Heretofore large lamps have been employed in suchdevices and because of this the testers were large and cumbersome and got excessively hot while in use.

The present tester comprises a cylindrical outer housing 5 into which the circuit connections 2-2 are extended at one end; the other end being open and is arranged to receive therein and to contain a reflector member 6. This has a rounded base end 2, in which an incandescent electric lamp 7 is mounted, and the lamp has electrical connection, in the usual way, with the circuit wires. The outer end portion of the reflector member has a peripheral flange 8 that seats Within an annular shoulder 9 that is formed at the outer end of housing 5. The arrangement and relationship of the housing 5 and reflector is such. as to leave an air space 10 between them, and this prevents transmission of heat from the lamp to the housing which would render it uncomfortable for handling.

Fitted within an enlarged outer end portion 5 of the housing 5 is a tubular extension 11 that terminates in a somewhat restricted outer end opening 12 about which a rubber cushioning ring 13 is fitted; this latter serving as a seat against which an egg, as designated on dotted lines in Fig. 1, is placed when tested.

In using the device, the egg is placed against the seat and the observer inspects the egg from the side opposite the tester the light from the latter illuminatingthe interior of the'egg to an extent sufiicient that one experienced can determine its condition.

The present device can be easily and quickly taken apart or reassembled. It is small and compact; will not become hot to an extent that would render it uncomfortable to handle. The use of the transformer makes possible the use of a small lamp and thereby cuts down the size of parts and amount of heat given. off.

It is to be understood that the proportion of parts and various details of construction could be changed Without departing from the spirit of the invention, and for this reason it is not desired that the claim belimitedonly to the details herein shown.

Having thus described my invention, what I claim is new therein and desire to secure by Letters Patent, is:

said. socket having an outer end enlargement forming a shoulder against which the reflector seats to limit its inward movement and a tubular extension fitted at one end in said enlargement of the socket and having a restricted outer vend opening. with a cushioning band fitted to said opening.

Signed at Tacoma, Washington, this 21st day of August, 1929.
