This invention relates to improved medical apparatus, and more particularly to an apparatus designed for testing urine or for any other purpose in which test tubes are employ-ed.

The primary object of the invention is to provide an apparatus of this character, composed of several parts which can be conveniently nested and house test tubes and other apparatus and containers in a relatively small space, so that the apparatus as a whole may be conveniently carried from place to place and will occupy but a minimum of space either in the package, satchel, bag or other container.

A further object is to provide an apparatus of this character which can be manufactured and sold at an extremely low price, which will greatly facilitate the testing of urine and the like, and permit convenient means for supporting test tubes during the heating or boiling, during the cooling action, and during the drying and draining action of the test tubes.

With these and other objects in view, the

invention consists in certain novel features of construction and combinations and arrangements of parts, which will be more fully hereinafter described and pointed out in the claim.

In the accompanying drawings- Figure 1 is a plan view illustrating my improved apparatus as a whole, with the parts nested and containing a number of test tubes althoughit is to be understood of course that apparatus bottles and other articles may be carried within the apparatus as well as test tubes; 1

Figure 2 is a view in vertical transverse section through the center of Figure 1;

Figure 3 is a perspective view, partly broken away, illustrating the employment of the container member of my apparatus during the heating or boiling of the contents of the test tubes;

Figure 4 is a perspective view, showing the rack member of my improved apparatus supporting the test tubes while the latter are cooling;

Figure 5 is a perspective View, showing the 1927. Serial No. 199,014.

:rack member supporting the test tubeswhile draining and drying, and in this View I have omitted the top plate of the rack member for the purpose of clearness although it is to be understood that the test tubes may be supported on the rack member without removing the top plate; V

Figure 6 is a fragmentary view on an enlarged scale of one corner ofthe removable top plate of the rack member.

My improved apparatus comprises three separate parts, namely, a container member A, a rack member B and a removable top plate C for the rack member B. The container member A has a cylindrical perforated wall 1, with a plate 2 fixed to one end of the wall and having openings 3 therein for the accommodation of test tubes 4 to support the test tubes in upright position with F their lower portions submerged in water 5 in any suitable receptacle 6 for boiling or heatingthe test tubes, as clearly shown in Figure 3. i

The rack member B comprises a perforated base plate 7 of cylindrical form and of h slightly smaller diameter than the diameter of member A so as to fit within the latter.

This base plate A is provided with a number of posts 8. I have shown three of these posts 8 although of course I may employ any desired number. Theupper ends of the post 8 are made with upwardly projecting tongues 9, narrower than the posts, providing shoulders 10 at opposite sides of the tongues.

The top plate G above referred to is made F with slots 11 to receive the tongues 9 and rest upon the upper ends of the posts 8, and this plate C is also provided with openings 12 for the accommodation of the test tubes 4: while 0 out removing the plate C from the posts 8,

I but for clearness of illustration I have shown this plate removed in Figure 5.

In utilizing the apparatus, the member A is positioned in the container 6, as shown in Figure 3, with the test tubes 4: in place and the contents of the test tubes boiled or heated as desired. Thesetubes are then removed and placed in-the rack member B for cooling,

as shown in Figure 4, and afterfthe tubes are washed they can be inverted and placed on the pins 13 for draining. and drying. -When the operation is ended, the top plate C'is removed from rack B, the casing member A is inverted, as shown in Figure 2 and the plate C is then disposed inside of member A and the rack B located inside of member A, above the plate C, the test tubes and other containers and articles used can be then placed in side of the rack member, so that the entire apparatus will be nested and assembled in small space for packaging, storage and shipment.

My improved apparatus provides a small,

compact, complete means for testing and it supplies a great need because heretofore apparatus for this purpose has been cumbersome and occupied considerable space.

While I refer to the member A as cylindrical and the base plate 7 and the rack B as circular and have so illustrated these parts f as I believe this to be the preferred shape, it is obvious that other shapes may be employed and various changes might be made in the general form and arrangement of the parts described Without departing from the invention. I therefore do not limit myself to the precise details set forth but consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of the appende-dclaim. v

I claim:

A rack of the character described, comprising a perforated baseplate, upstanding posts on the baseplate, removable plates supported on the upper endsofthe posts and having test tubereceiving openings. therein, and upwardly projecting pins on the baseplate adapted to receive test tubes in an inverted position.
