DIAGRAM OF THE FLOATS AND MACHINERY FOR 

 LOBSTER CULTURE. 



1. Barrels for support of float. Three barrels on the near side, and all on the far side, are 



omitted. 



2. Longitudinal beams, 6x6 inches x 39 feet. 



3. Transverse beams, 6x6 inches x 19 feet. 



3. Upper transverse beams, 4x6 inches x 13>*<> feet, 



4. Upper longitudinal beams, 4x6 inches x 39 feet. 



5. Mooring chain ; two others do not show in drawing. 



6. Mooring iron and buffer ; three others do not show in drawing. 



7. Corner brace of float. 



8. Wooden blocks supporting shafts. 



9. Shaft hangers. All unbabbited, save those supporting transverse shafts. 



10. Longitudinal shaft of float ; 1 inch in diameter, 26 feet long. 



11. Match gear wheels fixed to shafts by set screws. 



12. Vertical or paddle shaft supported by longitudinal beam (4). This shaft is 6% feet long 



and is made of two pieces (6 feet and \ l / 2 feet long) of %-inch galvanized gas pipe. 



13. Movable transverse beam which forms lower bearing of shaft. The beam of the middle, 



and the greater portion of the beam of the forward compartment are not represented. 



14. Paddle. Blades 4 feet long and from 5 to 7 inches broad are fastened by bolts to pipes 



screwed into the tee at the lower end of the shaft. 



15. Transverse shaft of float, 10 feet long. This shaft makes 108 revolutions per minute, and 



by means of a worm and wheel transmits power to the longitudinal shafts which re- 

 volve 9 times per minute. 



15. Transverse shaft of house-boat, 16 feet long. This shaft receives power from the engine 

 by means of a 2-inch belt running on an 18-inch pulley, and transmits the power to the 

 longitudinal shaft (22) of the house-boat, and the transverse shafts (15 and 26) of the 

 floats. 



16: 17. Universal joints and sliding joints which connect the transverse shafts of the house- 

 boat and float, and allow motion in all directions so that the swell and wave motions 

 do not disturb the operation of the machinery. 



18. Belt from engine. 



19. Gasoline engine 2J^ horse-power, speed 329 revolutions per minute. 



20. House on bow of boat. 



21. House on stern of boat. 



22. Longitudinal shaft of house-boat 19 feet long. The vertical shafts and the lower match 



gear wheels are omitted. 



23. Longitudinal beam across the middle of the well of the house-boat. This supports the 



longitudinal shaft (22). 



24. Well of house-boat containing three bags 6x6 feet x 5 feet. 



25. Transverse beam across well of house-boat for support of transverse shaft, 15 feet. 



26. Shaft and block of starboard float. 



27. Forward compartment of float. 



28. Middle compartment of float. 



29. Rear compartment of float. Each compartment holds a canvas bag (page 80) 12 feet 



square and 5 feet deep. 



30. Worm and worm wheel to reduce speed twelve times.
