EGG-TESTER.

SPECIFECATION forming part of Letters Patent No. 326,763, dated September 22, 1885.

Application filrd November '25, 1884. (Modeh) To all whom it may concern.-

Be it known that I, Casrnn MARTI, of Minneapolis, in the county of Hennepin and State of Minnesota, have invented a new and Improved Egg Register and Tester, of which the following is a full, clear, and exact description.

The object of my invention is to provide a new and improved device for testing eggs to ascertain whether they are fresh or not, and at the same time automatically counting the eggs and registering the number tested.

The invention consists in the combination, with a box, of a pivoted platform provided with one or more apertures for holding eggs, a mirror below one end of the platform, a registering device at one side of the box, and a pawl-rod connected with the platform and adapted to operate the registering device, all as will be fully described and set forth hereinafter.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a plan View ofmy improved egg register and tester, showingit held on an eggcase. Fig. 2 is alongitudinal sectional elevation of the egg register and tester on the line mm, Fig. 1. Fig. 3 is a cross-sectional elevation of the same on the line 3 3 Fig. 2.

In the top of the box A a cover or platform, B, provided with three apertures, O, at one end, is pivoted in such a manner that the one end swings down until it rests upon a pin, a, projecting from one side of the box, and the end provided with the aperture 0 is raised above the top edge of the box. The apertures O are of such size as to adapt them each to receive an ordinary egg. Below that end of the pivoted cover B,opposite the one provided with the aperture 0, a mirror, D, is held at an inclination in the box in such a manner that the eggs placed in the apertures O are reflected in the said mirror, and can be distinctly seen by a person looking upon the said mirror. On the outside of one end of the box a candleholder, E, is held, which is provided for holding a candle, F, which can be raised or lowered, so that its flame will throw the proper light upon the eggs held in the openings 0 in the pivoted cover B.

In a casing or box, G, on the outside of the box A, a wheel, H, is pivoted, which has a certain number of teeth, J, on the inner edge of its rim,and has the corresponding numbers produced on its outer edge. The numbers can run consecutively from 1 to 100, (more or less,) or the numbers can indicate dozens and quarters of dozens. This should correspond to the number of apertures 0 provided in the pivoted plate 13. The wheel H is provided with a tooth, K, projecting from the outer side, and adapted to engage with teeth L on a. wheel, M, parallel with and adjacent to the wheel H. There are ten teeth L on the wheel M, andfor each revolution of the wheel H the wheel Mis revolved one tooth by the tooth K. As many numbers are produced on the rim of the wheel M as there are teeth L on the said wheel. A pawl-rod, N, is pix oted to the apertured end of the swinging top or cover B, and engages with the teeth J of the ratchet-wheel H. A knob, O, is attached to the swinging piece P, pivoted on the inner surface of one of the sides of the box A, the stem 1) of the said knob passing through a slot, Q. The cover R of the box G is provided with a transverse slot at the middle, through which the numbers on the wheels H and M can be seen. The box A is provided with hooks T, for holding it on the upper edge of an egg-case, U, which may be of any desired construction, and may be divided into separate compartments for receiving the eggs,or may contain the eggs packed in chopped straw, or in any other suitable manner.

The device is used in the following manner: The wheels H and M are set at 0, and three eggsthat is, a quarter dozen-are placed in the apertures O of the pivoted top B and swing the same down into the horizontal position, thus causing the pawl rod or arm N to move the wheel H the distance of one tooth. The candle F illuminates the eggs, the figures of which are reflected in the mirror D, and can be seen distinctly. The good eggs have a light rosy color, whereas bad eggs look dark and bluish. The bad eggs can be detected in an instant, and thus a large number of eggs can be examined in a very short time by means of my improved apparatus. WVhen the wheel H has made one revolution, the wheel M is moved one tooth, and so on. The number of eggs taken from the egg-box can thus be counted very easily and rapidly. The device can also ICO be used as a counter alone, if it is not desired to examine the eggs. In case the counter is not to operate,the piece P is swung in the direc tion of the arrow to, so that the pawl-rod N rests upon the pin or stem 1) of the knob 0, whereby the lower end of the pawl-rod islifted when the top Bis swung down, thus preventing the said rod from revolving the wheel H. When the counting mechanism is to be operated again,the knob O is moved in the reverse direction of the arrow c.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In an egg register and tester, the combination, with a pivoted platform provided with one or more apertures for receiving and holding eggs, of an inclined mirror below one end of the platform, and a registering device operated from the said platform, substantially as herein shown and described.

2. In an egg register and tester, the combination, with a pivoted platform provided with one or more apertures for receiving egg of a device for holdingalight at the aperturcd end of the platform, an inclined mirror below the opposite end of the platform, and a registering device operated by the platform, substantially as herein shown and described.

3. In an egg register and tester, the combination, with apivoted plat-form having one or more apertures at one end, of an inclined mirror below the opposite end, substantially as herein shown and described.

4. In an egg register and tester, the combination, with the box A, of the pivoted eggholding platform B, the mirror D, the registering device, the pawl-rod N, pivoted on the platform 13 and serving to operate the registering device, the pivoted piece P on one side of the box, and the knob 0, connected with the said piece,and having a pin passing through a slot, Q, in the side of the box, substantially as herein shown and described.

5. In an egg register and tester, the combination, with the box A. of the pivoted eggholding platform B and the mirrorD, the box G, containing a registering device, the pawlrod N, connected with the platform B and adapted to operate the registering device, and the hooks T, for holding the box A on an eggcase, substantially as herein shown and de scribed.
