Patented Dec. 25, 1945 MANH OIiD SUPPORT FOR GAS ANALYSIS APPARATUS George W. Carlson, Bridgeville, Pa., assignor to Burrell Technical Supply Company, Pittsburgh, Pa., a corporation of Pennsylvania Application September 17, 1943, Serial No. 502,839

2 Claims.

This invention relates to portable cases and manifold supports for gas analysis apparatus, and it is among the objects thereof to provide a portable case for mounting the buretteabsorption pipettes and leveling bottle in a convenient and accessible manner.

The invention has for a further object the provision of a portable case construction 'proportioned to minimize interference with light and improve visibility of the pipettes and burettes, and which further provides sliding panels as side and partial top covers to expose the manifold support.

These and other objects of the invention will become more apparent from a consideration of the accompanying drawings constituting a part hereof in which like reference characters designate like parts, and in which:

Fig. 1 is a, view in perspective of a portable case embodying the principles of this invention;

Fig. 2 a front elevational view thereof with the cover removed;

Fig. 3 a view in perspective of the case illustrating the construction of the uprights and manifold; and

Fig. 4 a cross-sectional view partially in elevation of the manifold support.

With reference to Fig. 3 of the drawings, the structure therein illustrated comprises a base I, and a pair of uprights 2 and 2a having a, top 3 cut out at 4 and at 5 to receive extended top portions 4a and 5a, Fig. 1, of sliding panel or cover members 6 and 1, respectively.

As shown in Fig. 3, the uprights are provided with slots 8 and 8a for receiving tongues of the sliding panels 6 and I which in the closed position rests on the base I, and on the shoulders 4b and 5b of the uprights.

A manifold support generally designated by the numeral 9 is provided with cut-out portions In for receiving the necks ll of absorption pipettes l2 and the neck I3 of the burette M, Fig. 2.

The support is further provided with drilled holes l5 for receiving the glass cocks l6, Figs. 2 and 4, which have the manifold tubing 11 formed integrally with the wall thereof. Because of the cut-out portions 5 in the uprights, the manifold support 9 is fully accessible and entirely visible, which is necessary at times to follow the flow of the liquids through certain types of manifold.

By this construction there is no interference from above or from the sides of the case. A cross-piece I8 is secured to the uprights at some convenient portion between the base and the top, to which is attached the pipette supports l9, as shown in Fig. 2. The cross-piece [8 may termithe burette I4, a base 2| being shown in Fig. 3

for the burette.

When assembled with the gas analysis equipment as shown in Fig. 2, the sliding panels 6 and.

l are disposed in the grooves 8- to enclose and protect the equipment and a handle 22 is provided for' carrying the case.

This construction effectively closes the case and protects the glass equipment from damage.

The narrow upright members 2 and 2a cause less obstruction to the passage of light to the pipettes and other vessels, including the burette. The fact that the burette is less obstructed is important not alone from the standpoint of better accuracy of reading but it also permits the operator to hold the leveling bottle 23 closer to the water jacket in establishing the correct gas pressure in the burette prior to reading.

The manifold construction described in connection with Fig. 3 eliminates the conventional pipe hanger supports and may be employed in portable laboratory models where a clear view of the horizontal member of the manifold is desired.

alignment with said cut-out portions mounted in a manner to be exposed at the top and front of said case, and panels slidingly mounted in said uprights and having extending tops interacting with said cut-out portions to completely clos the container in assembled position.

2. A container for gas analysis equipment consisting of a base, side walls and top, the side walls being cut-out at the top, a manifold support extending across the top mounted to be entirely exposed to the front and sides and at the top of the container, and panels at the front and rear of the container having extending top portions fitted into the cut-out portions of the side walls to be contiguous with the outer faces of the top and side walls of the container.
