SCALE.

Application filed June 11,

To all whom it may concern.

Be it known that I, SAnoHIRo MIHARA, a subject of the Emperor of Japan, residing at lrardena, in the county of Los Angeles and State-of California, have invented a new and useful Scale, of which the following is aspecification.

This invention relates to devices for weighing articles, and more particularly for weighing eggs and thereby grading the eggs. One of the objects of the invention is to provide a device by which articles can be graded quickly and accurately.

' Another ob yec-tis to provide a device by which articles can be graded quickly as to weight and size.

Another object is to provide scales with means for receiving eggs of different sizes and having indicating means showing or indicating certain eggs to be of minimum grade in certain sizes.

Other objects will appear from the follow ingdescription and appended claims as well as from the accompanying drawing, in

-' which Fig; 1 is a side elevation of the device. Fig. 2 is a top plan View of the device. The scale beam 3 is pivotally mounted at- 4 in the uprights 5, as illustrated in the figures in the drawing. The uprights are right'7 serves to guide and limit the beam 3 in its movement. Two extension ends 8 project upwardly from the upright 7 sidewise of the end 9 of the beam 3 for guiding the beam in its vertical swinging movement,

fon'ning a shoulder 8 which serves as a rest or stop in the downwardmovement of end 9 of the beam. A pin 11 is disposed through the extension ends 8 near the top ends or a forming the stop'in the upwardmovement of the end 9 of, the beam 3. Near the end 12 of the beam, being the opposite end, a suitable number of openings of difierent sizes are provided to receive different sized eggs. Three

openings

13, 14 and 15 being shown in the drawing, but it will easily be understood that any other number of so differently sized openings can be provided that eggs can be placed in many different grades.

A weight 16 is provided on the underside of the beam to properly balance the device. An adjusting weight 17 is pIOVldGd on a 1920. Serial No. 388,243.

screw stem 18 for adjusting the balance of the device. A rocker arm 19 is provided at one end of the rocking shatt' t (forming the. pivot support of the beam). The rocker. arm 19 is provided with a geared member 20 disposed so as to engage with a pinion 21. An indicating member 22 is provided on the pinion 21 so as to extend. over the front face of a suitably graduated scale 23. In operating this device, an egg isplaced in one of the openings in the end 12 of the beam so that this end 12 will naturally tilt in a downwardly movement thereby causing a lifting movement of the end 9 of the beam 3, as will easily be understood. Normally, an egg is placed in the largest opening, that is in this case as illustrated in the drawing the opening 15. It the egg is of a size and grade as to be consideied of the best it will tilt the beam 3 so that the end 9 comes to a position indicated in dotted lines at 25 touching and bumping against the pin 11. If the beam does not tilt enough so as to bring the end 9 against the pin 11, the is not of the grade to which such an belongs when so tested in one of the holes or openings in the beam.

If not causing a touching of the end 9 against the pin 11 in the largest opening 15,

but. when placedin opening 14, it causes a 3 touching of the end 9 against the pinll in the second opening 14, then such egg belongs to the second grade.

If still not causing a touching of the beam with the pin 11, the egg does not even belong to the second grade and has to be'tested in the third opening 13; and so forth according to the number of openings in the beam. Three openings, however provide for the normal three grades of eggs.

The indicating member or hand 22 projects normally to the directioniudicated at 24 on the scale 23. that is the resting position of the device. The position indicated at 26 e indicated in dotted lines at 25, to eventually bring the indicating hand to a position near a point as indicated at 27;

Normally, however, can satisfactorily be graded by having the pin T1 in the position shown, and the eggs can quickly be disposed in one or two of the openings to establish the proper grade, as Will easily be understood.

Having thus described my invention, 1 claim:

in egggrading scales, a rocking beam having several holding means for each receiving and holding an of a dili'erent grade or size at points located at various distances from the rocking axis in one of its extremities and having means forthe counterpoise or weights in the other extremity.

2. ln egg-grading scales, a rocking beam. having its counterpoise or Weights adjus't ably embodied in one of its extremities and having several holding means for receiving and holding eggs at points locates at various distances from the rocking axis in the other extremity for establishing and ascertaining the grade of such eggs from the place taken in one of the holding and receiving means in relation to the predetermined balancing counter-poise.

3. In egg-grading scales, a rocking beam having several holding means for receiving and holding eggs of different grades at different points in relation to the rocking axis and having predetermined balancing means for holding the beam balanced when certain grade eggs are in their corresponding receiving and holding points in the beam.

4. In egg-grading scales, a rocking beam iaving a pendulous Weight, several holding means for receiving and holding eggs of different grades at diflerent points in relation to the rocking axis and having predetermined balancing means for holding the beam balanced When certain grade cans are in their corresponding receiving and holding positions in the beam, and stopping means removabl 1 disposed in relation to the beam for indicating the proper balancing point when certain eggs are in the proper receiving and holding position adapted to be removed for allowing an indication of the full and correct Weight of such eggs,

5. In egg-grading scales, a rocking beam having apendulous Weight, several holding means for receiving and holding eggs of difierent grades at dilierent points in re lation to the rocking axis and having pre determined balancing means for holding the beam in grade-indicating position when certain eggs are in the proper receiving and holding position in the beam, removable stopping means disposed in the path of: the rocking beam for indicating the margin of the grade, and scale indicating means for indicating the full and correct Weight of any eggs.

6. In egg-grading scales, a rocking beam, a pendulous Weight thereon, balancing means in the rocking beam, balance adjusting means in the beam, a removable stop for the movement of the beam for indicating the margin of the grade of certain eggs when disposed in the beam, and scale indicating means for indicating the full and correct Weight of such articles.

7. In egg-grading scales, a rocking beam, a pendulous Weight thereon, balancing means in the rocking beam, balance adjusting means in the beam, a stop removably dis posee in the path of the rocking beam for indicating the margin of the grade of eggs when disposed on the beam in proper position on the beam in relation to the rocking axis, the stop being removably disposed adapted to be removed for allowing a further free movement of the beam, and scale indicatingmeans for indicating the full and correct Weight of such eggs.

8. In egg-grading scales, a rocking beam, a pendulous Weight thereon, several holding means for receiving and holding eggs of different grades at different points spaced from the rocking axis at different distances according to the number of points, balancing means in the rocking beam, balance adjusting means in the beam, a stop removably disposed in the path of the rocking beam for indicating the margin of the grade of eggs Wien disposed in the beam in the proper receiving and holding position for such certain the stop being removably disposed adapted to be removed for allowing a further movement of the beam, and scale indicating means having means for indicating the grade of certain eggs in the different receiving and holding positions in the beam and having means for indicating the full and correct weight of such eggs.

In testimony that I claim the foregoing as. my invention I have signed my name in th presence oftvvo subscribing Witnesses,
