JLIUSJOHN MOJONNIER, OF OAK PARK, ILLINOIS, ASSIGNOB, TO MOJONNIER BROS. CO., OF PORTL, MAINE, A CORPORATION 'OF MAINE.

FLASH-HOLDER.

To all whom t may concern:

Be it known that I, JULIUs JOHN MOJON- Nmn, a citizen of the United States, residing at Oak Park, in the county of CookA and State of Illinois, have invented certain new and useful Improvements in Flask-Holders,

of which the following is a specification.

In the `co-pending application Serial No. 20,633, filed April 12, 1915, is described an apparatus and method of testing milk, in connection with which is illustrated and dei scribed an extraction flask. In carrying out the method described in this application, it is necessary to first shake the flask and 'afterward centrifuge it, or, in other words, subject the flask and its contents to the action of centrifugal force, in order to sharpl separate, -one from the other, the immisci le liquids within the iask.l

The present invention is designed as a holder for a plurality of the flasks during both the'shaking and centrifuging steps of the method described in the said co-pending application supra, thus making it possible to not only simultaneously carry out the process with a number of specimens in lieu of one but to also eliminate all undue handling of the iasks.

With the above and other objects in view, as will be apparent, this inventionconsists in the construction, combination and arrangement of parts all as hereinafter more fully` described, vclaimed and villustrated in the accompanying drawings, wherein Figure 1 is a front elevation of a holder constructed in accordance with the present invention, illustrating several {iasks therein;

Fig 2 is an end elevation thereof;

Fig. 3 is a vertical section taken along line 3 3 of Fig. 1, to illustrate the details of construction of one of the iask-receivingl 4 Specication of Letters Patent. P-tQmtgQd Jun@ im, 1913, Application med may 2o, 191e. serial No. 98,759. l I

sockets 15.' These pockets or sockets 15 are each to receive the lower chamber or end 11 ofan extraction flask F, the capacity and size of each holder being determined by the number of sockets or pockets. The formatlon of the base 14 and the arrangement of the sockets or pockets 15 therein is such that the latter are independent one from the other,

and if desired extend entirely through the former. A plate 16, of metal or other adaptable material, forms the bottoms for the sockets or pockets 15, as it is of the same di-4 mensions as the' base 14 and is secured to the under side thereof by a number of screws 17 piercing the plate 16 and threaded into the base 14. A. pad 18 of shock-absorbing material, such as rubber, is placed in the bottom of each pocket orsocket 15 to protect the iiash F to be located therein, from damage.

For retaining the flasks F in their'respective sockets or pockets 15, a cover or lid 19 is hinged to oneI longitudinal side of the base 14 and is of a width equal to approximately one-half of the width of said base. This cover or retaining member 19 is hinged to swing to a position where it will rest flush upon the upper face of the base 14, when in its operative 'posi-tion, and to swing away from the base when it is desired to release the flasks (see dotted line position in Fig. 3).

The free edge of the cover or retaining member 19 is provided with the approximately semi-circular recesses 20, one recess corresponding to and coperatin with each pocket or socket 15 for embracmg the upper portion of the lower chamber-11 of a flask F within the pocket. As the recesses 20 are spaced one from the other, a projection or tongue 21 is created between each pair of ladjoining recesses and at the ends of the 19 to a position where it rests flush upon the .base 14 and grasping both the base and the cover, the holder andthe flasks therein may be shaken, the flasks F being held in place by the cover. After this shaking, the holder with all of its asks F may-be placed in a centrifuge,V the action of the centrifugal force being sufficient to maintain the flasks in their respective sockets or pockets 15 andthe cover or lid 19 in its operative position. When the centrifuging is complete, the contents of the upper chambers 10 of the asks F may be Withdrawn Without removing them from the holder. rI`hus it will be seen that by the use of the present holder, of the size illustrated, thoughcf course the same may be made to accommodate a greater or lesser number of flasks, four tests may be conducted simultaneously, Without any chance of confusing or interchange of samples.

j Compared to the depth of each socket or pocket 15, the vheight of the flasks F' would cause them to be top heavy unless some means were provided to support .the project-p ing portions of the asks and also to prevent them from turning in the sockets, thereby maintaining the faucets or stop cocks 13 in fixed correlative positions. To accomplish this, la wire support is provided for each socket or pocket 15 and comprises a single strand of Wire bent annularly upon itself to create the loop 22, through which passes the upper chamber 10 of the cooperating fiask F. The ends of the wire are bent Aat right angles `to the loop 22 to form the spaced, parallel uprights 23, which support the loop 22 in a superposed position parallel to the base 14 and in registration with the cooperating socket or pocket 15. At their terj minals, the uprights 23 are embedded in the base 14 whereby they are permanently held fixed in any suitable manner, such as by riveting. In practice, it is desirable to keep all of the loops 22 within the connes lof the vertical planes of the ends of the base 14, so that no portions thereof project beyond the base. To this end, the uprights 23 of the medial supports are embedded inthe base 14 equidistantly upon each side of one end of the diameter of the adjoining socket or pocket 15, at right angles to the longitudinal side of the said base; while the uprights 23 of the end supports are both at one side of such diameter, so that the loops of these supports are positioned inwardly toward and in close proximity tothe `loops of the next adjacent supports. To prevent damage to messe? the flasks F and the stop cocksor faucets 13 thereof, the loops 22and the uprights 23 are covered with the rubber or other resilient tubing 24, which contacts directly with the flasks and their faucets or stop cocks.

In se,the flasks F are .placed in the sockets or pockets 15 and are held therein by the cover or retaining member 19, in the manner heretofore described. When so located, the upper chambers 10 of the Vflasks rest in the loops 22,while thesto'p cocks or faucets 13 thereof project through the'spaces between uprights 23 and terminate beyond the plane of the longitudinal edge of the base 14. By having the supports each constructed of a single strand ofy wire, it is possible to place a flask Within the holder by inserting it through the loop 22 with the faucet or stop cock 13 thereof alined with the space between the uprights 23; and vreversely, the flasks may be similarly removed. After the iasksF have been filled with the necessary samples, ingredients, etc., and

placed within the holder, all of the dasks in said holder may be shaken and centrifuged, and the faucets or stop cocks 13 opened to allow thecontents to escape, without removing them from the said holder. Thus it is seen that a number of flasks F may be handled as a unit, and in the time normally consumed, heretofore, by the same operations in connection with one flask. By the spacing and arrangement of the uprights 23, the faucets or stop cocks 13 of the flasks F are held fixed, and the contents of the flasks may be allowed to escape therethrough into dishes without changing the positions of the asks or their faucets orstop cocks.

In order to provide for the tiltin of the holder so that the contents of the asks F may readily flow therefrom when the faucets lates the angle of said base to the horizontal' plane, which angle may be adjusted at will by means of said set screws.

vIt is to be understood that the present holder may be used in any connection Where itis desired to provide a container for a number 0f flasks ortest tubes, it being ,possible to change the details of construction without departing from the spirit and'scope hereof.
