2 Claims.

Yent invention are adapted for extracting samples of various different substances, but `for the purposes of illustration a sampling device constructed in accordance with my invention will be .described as used in connection with the extracting of samples of resin from barrels. It will be understood, however, that devicesV accordance with my invention may be used for extracting .samples of other substances fromcontainers in. general.

Heretofore the practice generally followed in `extracting samples of -rosin from barrels has .been

`to remove the top of the :barrel and to vbreak out va sample from the top of the resin containedV in the barrel. `This practice is objectionable in that vafter 4the rosin at .the top ofthe barrel is .broken for permitting the removal -of a .sample vand the topboards of the .barrel replaced, rain water is .apt to kfind its Way into the barrel and to spoil the resin. Furthermore, kbreaking vof therosin .at the ,topof the barrel followed by replacing the Ybarrel top more or less loosely results in loss Vofsome of the broken rosin when the barrel is moved around.

In .accordance with my invention, I extract a clean, true Vsample'from a barrel or other .container through a small opening in ,thecontainen which opening normally -is covered by a closure which is adapted to be removed and replaced easily.

An object of my invention is to provide an improved device for extracting samples from a barrel or the like in the manner generally set forth above, i. e., in such a way as to dispense with the necessity of removing the top of the barrel. Another object is to provide a device of a character referred to by means of which a clean, smooth, truely representative sample may be extracted without its being subject to the marring action of a cutting tool or to unusual conditions, such as local heating which, if present, would change the properties of the sample so as to render the latter different from the contents of the container. Other objects will become apparent from a reading of the following description, the appended, claims, and the accompanying drawing, in which:

. By way of illustration a preferredembodiment of my improved sampling deviceis illustrated in 2) 9 `connection with a barrel A providedwith atop filler openingv i, and Withan :aperture :2 its side wall.. The sampling .device generally .designated B comprises a' hollow samplereceiving-.part

3 ,of considerably .smaller .c ross .section than .the l2.5 aperture 2 and r`a1 pair fof supporting vparts .or 'v arms ,ii-.t extending laterallyfrom ythe'.. s.,arn ple receiving part 3 and being ladapted to `be I secured to the side wallof the barrel adjacent to, the

`aperture 2 for supporting the sample-rece' Ing i30 part 3 in the .barrel in spaced relation'-tpfthe lperiphery of the `aperturelfand 1 in Vsubeta,ntial axial alignment with the latter. Preferably, the supporting arms 4 include portions 5 adapted to lie against the wall of the aperture 2 and flanges 6 adapted to lie against the outside of the container Wall immediately adjacent the aperture 2.

The sample-receiving part 3 may comprise two separable sections 3a and 3b adapted to be assembled as in the illustrated form by telescoping one within the other. As shown the section 3b is adapted to be set telescopically within the section 3a.

It will be understood that it is desirable that the sampling device be so arranged that the sample .can be removed easily therefrom after the device itself has been removed from the barrel, and to this end the sections 3a and 3b preferably are constructed in such manner that their respective walls may be sprung apart somewhat for releasing the sample. In the illustrated form the section 3a comprises a back Wall 1, twoY side wa1ls`8--8, and anges 9-9 extending along'the forward edges of the side walls, but terminating in spaced relation one from the other.

sides in the provision of an expansible samplereceiving part whose walls may be sprung apart relatively outwards from the sample to release the latter without breaking it.

In use, the sampling device B is inserted through the aperture 2 and positioned as shown best in Figure 2 with the supporting parts II holding the sample-receiving part 3 in the position shown and lthe wall` 1 of the section 3a closing the space between the free edges of the flanges II of the channel-shaped section 3b. In order to close the aperture 2 a spring metal cap closure I2 is inserted in the aperture and nails or other fastening means are driven through the cap and preferably through the supporting parts II and into the barrel wall. The container is then filled through the top opening I, which then is closed by any suitable means. When the molten rosin is poured into the barrel it, of course, will ll the hollow part 3 of the sampling device which is open at both of its ends, thus permitting it to be filled readily.

In order to obtain a true sample of the hardened rosin the nails I3 are withdrawn and the ,closure I2 is removed. The supporting arms 4 are then bent outwardly into parallelism with the axis of the sample-receiving part 3 as shown in Figure 6. Thereafter the rosin surrounding the sample-receiving part 3 is loosened by means of a hollow cutting tool I4 which is of greater diameter than thesample-receiving part 3 and which is of slightly smaller diameter than the aperture 2. This will permit the sampling de- 1 vice to be removed bodily from the barrel after which the sections 3iL and 3b are separated and 'the clean, smooth, true sample is dislodged from the section 3b or the section 3a as the case may be.

jItA is apparent that a sample obtained in this manner will be truly representative of the rosin within the barrel since the sample has not been subjected to any cutting action, heating, or other modifying conditions.

By the use of my device it is unnecessary to remove the top of the barrel and to break the rosin therein in order to secure a sample. I thus eliminate the damage to the rosin caused by rain water seeping through the top head and lying on the broken rosin. Furthermore, by using my device there will be no loss of broken rosin sifting out through cracks in and around the rhead' where barrels are rolled or handled. The timer necessary to obtain a sample and hence the expense of sampling is greatly reduced. Since it is unnecessary to remove the barrel top in order to obtain a sample, it is possible to construct the barrel in such a manner that the top ts into a croze in the same manner as the bottomwhereby the barrel is greatly strengthened. With this construction, if the barrel is stored for any length of time and if the bottom shows a tendency to rot, the barrel may be up-ended so as to position the top wall underneath and in this way the barrel will remain in good condition for a much longer time thanV when the barrels rest on their bottom heads only during the entire time they are in storage. Y

Although av practical and the at present preferred form of my invention has been shown and described for the purposes of illustration, it will be understood that Various modications may be made in the specific construction and arrangement of the parts without departing from the invention as denedin the claims.

I claim:

l. The combination with a container having a wall with an aperture therein; of a sampling device including a hollow part of less cross sectional width than said aperture positioned in said con- :tainer in axial alignment with said aperture for receiving a sample; a supporting arm extending from said hollow part to said wall and being secured thereto for supporting said hollow samplereceiving part in said container in alignment with said aperture in spaced relation with the periphery thereof, said supporting arm being adapted to be bent outwardly into substantial parallelism with the axis of said aperture to permit use of a hollow cutting tool for removing said device from said container; and a closure for said aperture iitting over said device and being detachably secured to said container. A

V2. A combination as set forth in claim-l in which the hollow sample-receiving part comprises two separable sections.
