These and other features and advantages of their ends being supported by uprights 22 and 23 which are mounted on the branch tables as shown in Fig. 1. Similar longitudinal banks of shelves 24 and 25 are mounted centrally above the branch tables 2 and 4, the ends of said shelves being table.

In the embodiment illustrated, the branch tables I and 3 are each provided with a bank of outlets 29 for gas, etc., here shown to be three in number, which are arranged in longitudinal alignment beneath the respective shelves 2!] and 2!, centrally of said branch tables I and 3 so as to be equally accessible from either side thereof, and the branch tables 2 and 4 are each provided with a like number of outlets 30 arranged beneath the respective shelves 24 and 25.

If desired, the banks of outlets 29 and 30 may be alike in character, for example one outlet of each bank may be connected to a source of compressed air, while another may be for gas and the third for steam, so that each branch table is provided with the same facilities. On the other hand, theoutlets 30 of branch tables 2 and 4 may be of a difierent character from the outlets 29 of tables I and 3, for example the outlets 30 may be for supplying electric current, vacuum, etc. With this latter arrangement it will be evident that the laboratory workers stationed at all of the working bays A, B, 'C and D will each be within easy reach of both banks of outlets 29 and 30, and all of said outlets may be provided with double taps so that they may be used simultaneously by the workers on both sides of the' respective branch tables.

The lower portions or stands supporting the branch tables I, 2, 3 and 4 may be provided with I be stationed in each angular area of the cross,

with resulting economy of space.

Waste chutes 33 may be provided at the ends of branch tables I and 3 beneath the sink sections, and the backs of the various cupboards are preferably provided with removable panels permitting access to the plumbing. The various fume compartments of hood may be provided with steam bath openings 34 designed to fit standard equipment, and with small drains 35=for dis posing of substances giving oil noxious vapors. A push button, not shown, is provided beneath the edge of each branch table for summoning laboratory helpers.

The foregoing convenient arrangement of all the apparatus and equipment in the cruciform structure, .which insures equal accessibility to the chemists in each working bay, eliminates the traditional inconveniences, time losses and extra steps which are characteristic of straightdine work tables.

Although one particular embodiment of the invention has been shown and described for purposes of illustration, it will be evident to those, skilled in the art that various changes and adaptations may be made therein without departing from the scope and spirit of the invention as defined in the appended claims.

The invention claimed is:

1. A laboratoiy table for chemists comprising a plurality of connected branch tables arranged in the form of a cross providing a plurality of working bays in the angular areas between the respective branch tables, and a fume hood mounted in the center of said table at the intersection of the branches of the cross, said hood having individual access openings facing the respective working bays formed by said branch tables.

2. A laboratory table for chemists comprising four branch tables arranged in the form of'a cross providing four working bays in the angular areas between the respective branch tables, a fume hood mounted in the center of said table at the intersection of the ,cross, and individual fume compartments in said hood having separate access openings facing the respective working bays formed by said branch tables.

3. A laboratory table for chemists comprising four branch tables arranged in the form of aright-angled cross providing four working bays in. the angular areas between the respective branch tables, a fume hood mounted in the center of said table at the intersection of the cross, and individual fume compartments in said hood having separate accessopenings facing the respective working bays formed by said branch tables.

4. A laboratory table for chemists comprising four branch tables arranged in theform of a right-angled cross providing four working bays in the angular areas between the respective branch tables, a fume hood mounted in the center of said table at the intersection of the cross, individual fume compartments in said hood having separate access openings facing the angular junction pointsof the respective branch tables, and banks of outlets mounted centrally on each of said four branch tables in position to be accessible from both sides thereof, the outlets on each branch table being similar to the outlets on the corresponding aligned branchtableand being of a difierent character from the outlets on the inter-
