Application filed September 25, 1922. Serial n teaaso.

To (ZZZ whom it may concern Be it known that I, ANTON A. ANDERSON,

a citizen of the United States, residing at l/Vilder, in the county of Jackson and State of Minnesota, have invented certain new and useful Improvements in Sampling Dippers, of which the following is a specification, ref erence being had to the accompanying drawings.

This invention relates to for its object to provide a dipper particularly adapted for sampling purposes.

It is another object of the invention to provide a device of this character which permits all of the contents of the device to be discharged without requiring the device to be inverted.

It is also an object of the invention to provide a device of this character wherein the 20 bowl portion is constructed to substantially form an opening in the matter so as to elimi= nate resistance to the insertion of the dipper as far as possible and thus prevent adhering of the matter to the bowl.

It is still a further object of the invention to provide a dipper of this character having an outlet, and a strainer inthe outlet, the body portion of the bowl adjacent the strainer being disposed in angular relation to the strainer to prevent misdirection of the matter when the device is being emptied.

With these and other objects in view, the invention consists in the improved construction and arrangement of parts to be hereinafter more particularly described, fully claimed and illustrated in the accompanying drawings, in which Figure 1 is a perspective view of a sampling dipper constructed in accordance with an embodiment of the invention;

Figure 2 is a longitudinal sectional view of the dipper; and

Figure 3 is a top plan view, the handle being shown in section.

In weighing and sampling cream, in order to ascertain the amount of butter fat con tained therein it is desirable that the testing operation be accomplished as rapidly as possible. With an ordinary form of dipper or receptacle there is a possibility of a portion of the cream remaining in the dipper aftei the sampling operation, unless the operator clippers, and has dipper, which It is essential that Y be emptied so that placed in another will be no cream takes the trouble to invert the of course requires time. the contents of the dipper when the dipper is again container of cream there in the dipper to interfere with the'testing operation about to be accomplished.v It is also desirable that the cream to be tested be free from partially churned lumps of cream.v In order to-comply with the above-re quirements, and at the sametime obtain the desired results-in the sampling or testing operation, there is provided a novel form of sampling dipper comprisin a body memher or .bowl 5. This bowl is substantially a distorted cone as the side 5 of the bowl extends ,at. a greater inclination than the remaining side portions 6 of the bowl, so as to position the upper edge '7 of the wall portion 5" a greater distance from the axis a of the bowl than the remaining corresponding pointsof the bowl. The advantage of the distorted shaped bowl is that the bottom of the bowl istapered so as to eliminate resistance as far as possible and also prevent to a large extent adhering of the cream to the bottom of the dipper.

' The wall'p'ortion 5" and adjacent portions of the wall portions 6 of the bowl are provided with an Ushaped outlet extension 9,

said extension being longitudinally tapered and laterally curved to provide a spout 10.

The upper edgesll of the spout are inclined outwardly and downwardly with respect to the wall of the bowl. The bottom 12 of the spout is also disposed at an outward and downward inclination to the adjacent wall portion 5 of the bowl. The

longitudinally tapered features of the spout permits the formation of a mouth 13 of a size to permit the cream to be discharged into a receptacle having a restricted opening. It will benoted that the inclination ofthe wall portion 5 is considerably greater than the inclination of the remaining portions of the wall of the bowl. It will also be noted that the bottom 12 of the spout inclines or div'erges with respect to the wall portion 5. The advantage of this is that the wall portion 5 serves to direct all ofthe: cream. to the spout with only a slight lateral tilting of the bowl required, the inclined position of the spout facilitating the discharge of cream therefrom.

In order that churned lumps or like semisolids in the cream may not pass through the spout in the testing or sampling operation, there is provided a novel form of strainer 1a. This strainer may be made either of wire mesh fabric or perforated plate. For the purpose of illustration the strainer is shown as formed of wire mesh fabric. form to the opening in the side of the bowl at the inner end of the spout 10, the strainerbeing substantially fiat, or in other words, does not conform entirely to the curvature of the conical. forn'iation of the bowl. The'upper edge 15 of the strainer, however, forms a continuation of the upper end of the bowl. The strainer is also inclined downu' ardly and outwardly so that the lower end portion 16 of the strainer extends into the spout, thereby disposing the strainer in an inclined position and at the same efficiently covering the inner open end of the spout. By this arrangement it will be noted that the strainer is disposed substantially parallel to the opposite wall portion of the. bowl so that when the dipper is tilted to discharge the contents thereof the strainer will be normally disposed in a horizontal plane, regardless of the conical formation of the bowl. This prevents the cream from flowing over the upper edge 15 of the strainer. As the spout 10 of the bowl is inclined downwardly with respect to the strainer and the bowl. there is no possibility of cream remaining in the spout after thebowl has been emptied. The inclination of the wall portion 5 as previously stated serves to direct all portions of the cream to' the strainer.

To facilitate handling of the bowl a handle member 1? is provided, said handle member extending in the same general direction as the rear wall portion of the bowl and being formed from a length of substantial wire return-bent to provide parallel members substantially parallel with the axis a. The ends 18 of the wire are secured to the back of the bowl at points adjacent to a plane intersecting the axis a and the axis of the handle 17. The bight portion 1.9 of the length of wire is extended outwardly and formed into a hook by means of which the dipper may be conveniently supported.

In the actual use of the device it is to be noted that it is a. very simple matter to pour the sample into the bottle without spilling the cream on the outside thereof. while the strainer prevents any lumps or churned cream from entering the bottle. This latter feature is important. inasmuch as the presence of lumps in the sample would preclude making a fair test. An other distinct feature of importance is the Thestrainer is constructed to con-' fact that the device is very easily rinsed out by dipping it into the next batch to be tested and throwing the first dipper full back into the can so as to wash off the slight quantity of cream in the first batch that might be adhering to the dipper. This simple operation prevents any cream of the first batch from mixing with the sample taken from the next batch, it being well known that any such mixing would defeat the purpose of the test inasmuch as different batches seldom, if ever, contain the same quantity of butterfa t. Another advantage is that the dipper is easy to hang on the can as it terminates in a hook like handle, t being intended that the dipper be filled immediately upon filling the can and beforea richer cream is able to rise to the top, the dipper being then hung on the can while weighing is effected, the sample remaining in the dipper until weighing is accomplished. After the weighing is over with, the gate of the weigh can may be opened to permit the cream to run out while, at the same time, the sample in the dipper may be poured out into the composite sample bottle, thereby saving a good deal of time.

A very important feature is the downward and outward inclination of the outlet spout 10. The advantage of this downward inclination lies in the fact that the spout will not retain lumps of coagulated cream or any foreign matter when raising the dipper from the liquid. It is obvious that if the dipper be inserted within a vol umn of liquid from which the sample is to be taken, any lumps settling on the spout will be washed off when the dipper is brought up through the liquid owing to the fact that the inclination of the spout will cause a strong current of liquid to pass over it in a downward and outward direction.

From the foregoing it will be readily seen that this invention provides a. novel dipper particularly adapted for use in connection with testing cream and arranged so that the testing operation may be accomplished with rapidity and accuracy. All of these features are possessed by a device which is compact in form and which'in view of its simplicity can be manufactured in large quantities from a small amount of material.

That is claimed is i 1. A sampling dipper comprising an inverted conical shell having a portion of its side cut away downwardly from its upper edge, a downwardly and outwardly inclined discharge spout on the shell at the edge of the cut away portion, and an elongated handle secured to the shell, the downward in clination of the spout preventing the remaining thereon of any lumps when the device is withdrawn from a volumn of liquid into which it has been previously dipped.

2. A sampling dipper comprisin a retacle is withdrawn from a volume of liquid ceptacle having a portion of its side out into which it has been previously dipped, 10 away downwardly from its upper edge, a said current operating to wash off any lumps handle on the receptacle, and a downwardly tending to adhere to the spout.
