HANGRUM AND ROLAND O. TOEVS, 0] LOS ANGELEB, CALIFORNIA. Application filed June 88, 1828. Serial No. 647,219. To all whom it may concern. Be it known that we. RICHARD L. MAN- GRUM and ROLAND 0. Tours. citizens of the United States. residing at Los Angeles. in the county of Los Angeles and State of California. have jointly invented new and useful Improvements in Tanks. of which the following is a specification. Our invention relates to tanks and it is an improvement upon our tank disclosed in our application for United States Letters Patent filed December 21. 1922, Serial No. 608.163. which tank is composed of a plurality of sections welded together and reinforced at their joints. providing a solid structural tank which is strong. durable, fluid tight. fire proof and economical in construction. The main object of our invention is to provide improved reinforcing means at the oints between the sections. thus providing a stronger. more durable and more eflicient tank than our former tank above mentioned, or any other known tank. Other objects and advantages will appear hereinafter. and while we show herewith, and will describe a preferred form of construction. we desire to be understood that we do not limit ourselves to such referred form. but that various changes an adaptations may be made therein without departing from the spirit of our invention as hereinafter claimed. Referrin to the drawing which forms a part of this specification: Fig. 1 is a plan view of our tank. Fig. 2 is a vertical transverse section of our tank taken on line 2-2 of Fig. 1. Fig. 3 is an enlarged fragmentary vertical sectional view of our tank illustratin the joint for securing the cover to the body of the tank. Fig. 4 is a fragmentary sectional view taken on line 4-4 of Fig. 2 showing one of the vertical joints between the body sections. Fig. 5 is a fragmentary sectional view taken on line 55 of Fig. 2 showing the joint between the body and the bottom of the tank. Fig. 6 is a view similar to Fig. 5 of a modified form of joint between the body and bottom of the tank. Fig. 7 is a view similar to Figs. 5 and 6 of another modified form of joint between the bottom and body of the tank. In the drawing 1 indicates the bottom of my tank. 2 the body. and 3 the top thereof. The bottom 1 is composed of a plurality of metal plates 4. 5. 6 and T. the plates 4 and 5. the plates 4 and 6. and the plates 5 and 7 being joined together at their meeting side edges by joints 8 comprising upturned flanges 9 at said edges which flanges are welded together at their upper edges as indicated at 10. The joint 8 uniting the plates 4 and 5 extends diametrically of the bottom 1 and the joints uniting the plates 4 and 6 and the plates 5 and 7 extending parallel to said diametrical joint uniting plates 4 and 5. The adjoining ends of the plates 4. the plates 5. the plates 6 and the plates 7 are also united by joints 8. The construction of the top 3 is the same as the construction of the bottom as above described and a detailed description of said top is therefore not necessary. The body 2 is composed of a plurality of superimposed annular units ll. Each unit 11 comprises a plurality of arcuate plates 12 joined together at their vertical edges by joints 13. each of which joints comprises outturued flanges 14 on adjoining edges of said plates and a T-bar 15, the leg member 16 of said bar extending outwardly between said flanges and the head member 17 of said bar resting against the inside of said plates 12. said leg member 16 of said T-har and the flanges 14 being welded together at their outer edges as at 18. and said head member 17 of said T-har being spot welded to the inside of the plates 12 as at 19. The units 11 have formed at the lower and upper edges of the plates 12 external annular flanges 20 and 21 respectively. The ends of the joints 8 at the periphery of the bottom 1 are cut arm as at 22 to accommodate an annular ange iron 23. the base flange 24 of which an e iron being external of its vertical flange 25 and said base flange resting upon said bottom with its outer peripheral ed e coinciding with the peripheral edge 0 said bottom. The lowermost unit 11 telescopes over the vertical flange 25 of angle iron 23 and the base flange 20 of said unit rests upon the base flange 24 of said angle iron with its outer edge coinciding with the outer edge of said base flange 24 and the bottom 1. The outer edges of the bottom 1, flange 24 and said flange 20 are welded together as indicated at 26 thus forming a most efi'ective reinforced joint 27 between the bottom 1 and the lowermost unit 11. The an le iron 23 is spot welded at its upper e ge to the inside of the lowermost unit 11 as at 28. The superimposed units 11 are united together by joints 30, each of which comprises the flange 21 of one unit, the flange 20 of the unit above, and an annular T-iron 31, the leg flange 32 of said T-iron being external of the vertical head flange 33 and extending between said flanges 20 and 21, with said unit telescoped over said head flange. The outer edges of said flan es 20, 21 and 32 coincide and are we] ed together as indicated at 34, while the edges of the head flange 33 are spot welded to the inside of said units 11. as at 35. The joints 8 between the bottom plates 4 and 5 are cut away at the center of the bottom 1 to receive a disk 36, which is welded to the inside of said bottom centrally thereof. A post 37 extends centrally longitudinally of the tank and rests on and is welded at its lower end to the disk 36. A disk 38 is welded on the upper end 'of post 37. The upper end of the post 37 is centrally secured in position by radial angle bars 39. the inner and outer ends of the vertical flanges 40 of which bars being cut away a short distance as at 41 and 42 respectively. so that the end portions of the upper horizontal flanges 43 of said angle irons rest respectively upon the disk 38 and the upper flange 21 of the uppermost unit 11, and are welded to said disk and said flange. Arcu'ate angle irons 44 are placed between the outer ends of the angle irons 39 with their horizontal flanges 45. which. are external of their vertical flanges 46, resting upon said flange 21 of said uppermost unit 11 and with their vertical flanges 46 resting against the inside of said uppermost unit. the outer edge of said flanges and 21 coinciding. The cover 3 rests upon the flanges 45 of angle irons 44 and the flanges 43 of angle bars 40 with the edge of said cover coinciding with the outer edges of flanges 45 and 21 and the outer ends of angle bars 39 and said outer edge of said cover is welded to the outer edges of the flanges 45 and 21 and to the outer ends of said angle bars and the outer edges 9f said flange 21 as indicated at 47, thus forming an etl'ective joint 48 between said cover and the upper edge of the uppermost unit 11. The angle irons 44 are spot welded at their lower edges to the inside of said unit 11 as at 49 and at their corners to the under side of rover 3 as at 50. manhole 51 may be located in the side of the tank at the bottom thereof. Said manhole may consist of a box-shaped member 5:2 open at its inner end and fitted at said end within an opening 53 in the wall of the lowermost unit 11 and detachably closed at its outer end by a plate 54. which is bolted by bolts 55 to an external flange 56 on said outer end. An inturned flange 57 may be formed around the inside of the opening .33 and the inner ends of the upper and side walls of the member 52 welded to said flange 57. while the lower wall of said member may be welded to the bottom 1. A vertical ladder 60 may be located atone side of the tank. which ladder may be welded at its lower end to joint 27 and at its upper end to joint 48. and braced intermediate its ends by braces 61 welded at their inner ends to joints 30 and at their outer ends to the ladder. In the modified form of joint 27 the flange 20 rests directly upon the bottom 1 and an annular angle iron 62 fits within the unit 11 with its vertical flange 63 against the wall of said unit and its lower horizontal flange 64. which extends internally from said vertical flange. resting upon the bottom 1. The outer edges of the flange 20 and the bottom 1 are welded together as indirated at 65. The edges of the flanges 63 and 64 of the angle. iron 62 are welded to the unit 11 and the bottom 1 as at 66 and 67. In the modified form of joint 27 shown in Fig. 7 an annular T-iron T0 is substituted for the angle iron 23. the head member 71 of said angle iron resting upon the bottom 1 with its outer edge flush with the outer edge of said bottom. and the unit 11 being telescoped over the vertical flange 72 of said T-iron with the flange 20 of said unit resting upon the outer arm of the head member 71. with the outer edge of said flange coinciding with the outer edge of said arm and the bottom 1. which outer edges are welded together as indicated at 73. The upper edge of the member 72 of the T-iron is spot welded at 74 to the inside of the unit 11, while the inner edge of the head'member 71 of said T-iron is spot welded to the bottom 1 as at 75.
