yTANK STRUCTURE AND LUG THEREFOR.

. Application med June 24, 1924. serial No. 722,024.

To @ZZ whom t may concern Be it known that I, VVrLLiAM WV. Fono, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia `and State of Pennsylvania, have'invented `new and useful Improvements in a Tank Structure and Lug Tlierefor, as set forth in the annexed specificationA My invention relates to new and useful improvements in a tank structure and lug therefor, and has for its primary object to provide means Aof different characters all acting to strengthen the tank structure. Y

Another object of the invention is to provide a sister tank lug as a connection for the ends Vof the hoop whereby `a straight double pull may be exerted onv said'hoop to facilitate the tightening thereof and assist in properly maintaining the hoop in position;

further object of this invention is to i' provide a tank lug of open or skeleton conatmospheric conditions as well as to protect it against attacks by acid or gases which may be floating in the surrounding atmosphere thereby greatly increasing the life of the hoops.

With these ends in View, this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated'by' the' claims.

Inl order that those skilled in the art to which this invention appertains, may understand how to make and use the same, I will describe its construction in detail, referring by numerals to the accompanying drawings forming a part of this application, in which Fig. l, is a fragmentary sectional side elevation of aV tank having my improvements applied thereto.

Fig. 2', is an enlarged plan view of one of the tank rafter brackets.

Fig. 3, is a section at the line 3 3 of Fig.

Fig. 4, is a perspective view of the same.

Fig. 5, is an enlarged plan view of one of the tank lugs.

Fig. 6, is a side elevation thereof.-

Fig. 7, is an end View ofthe same` Fig. 8, is a section at the line 8-8 of FigL.

In carrying out my invention as here ern'-V Vbodied, 2 represents a tank of any usual or well known construction such as are used for storing water and the like in large quantities on tops or buildings and towers. The walls of such a tank are held together, supported or braced by a number 'of hoops 3 formed from metal rods and having their ends threaded as at4 to receive the nuts 5:

In order to fasten the ends of a hoop in place and permit tightening of the same with a straight pull Ain opposite directions, I pro` vide a'tank lug 6 the structural details of which are illustrated in F igs.V 5 to 8 inclusive.

This tank lug is of VsisterWcO-nstru'ction including a body 7 the' inner surface fof which is arcuate longitudinally as indicated at 8 so as to approximately correspond to the curvature of the tank walls. At each end of the bodyy but offset relative to each' other is a bearing surface 9 having an opening l0 therethrough for the passage of an end ofr a hoop. In alignment with each opening l() but at the opposite end ofthe body is a recess 1l in which the hoop is seated so that one of these recesses is rectly beside each bearing surface.

Intermediate each bearing surface and its associated recess the body is apertured as indicated at 12 thereby providing two side walls 13 and an intermediate partition 14.

After the hoop has been placed about'the tank one end is inserted in 'a recess ll and then passed through the opening 10 in endwise alignment therewith while the opposite end of the hoop is inserted in the other recess l1 and passed through the other open#v ing 10. Next the nuts 5-are screwed on the threaded projecting ends of the hoop until they engage the bearing surfaces 9 after which the screwing of the nuts on the ends of the hoop will draw the latter taut fromtwo opposite directions so that a greater andV the strain on the hoop to twist orturn thev lug in one direction is counteracted.` by a As this ranking is of the f t the elements.V 1

In order to strengthen the upper edge of the tank and also provide means for holding the rafters of the tank top, I provide a tank y rafter bracket l5 the construction of which is shown in detail in Figs. 2 to 4 inclusive,

wherein the lnumeral 16 denotes a stirrup con'iprising a bottom Wall l?, an end Wall ISand a pair of spaced side Walls l9,`the latter having holes 2O therethrough. From the bottom Wall 17 of the stirrup projects a trunnion 2l which passes through a hole 22 in the step 23 of the hanger 2li. Said hanger in addition to the step 23 includes a riser 25 from the upper end vof which projects a plate 26 adapted to overlie the upper edge of the tank Wa-ll, the latter preferably being notched toreceive the plate 26 so that the upper surface of said plate will lie Hush With the extreme top `edge of the tank Wall.

' At .the outer end ofthe plate is formed a depending flange 2? adapted to engage the outer surface of the V tank wall.

As will be readily noted the construction of thisrrafter bracket is such that when placed on the edge of a tank Wall it requires no fastening means Vto hold it in position. Any desirable number of these brackets may be used, the same being placed in alignment on opposite sides of the tank so that the ends of a rafter 28 may be set in the stirrups,

these being swung to any angle on' their respective hangers to compensate for the curvature of the tank, and When a rafter is in place bolts 29 are inserted in the holes 2G and passed through the ends of said rafter Which .Will preventany tendency of the tank Walls to bulge or flare outward. These bolts are held in place by nuts 30 screwed on their threaded ends. Y

The stirrup is held on the hanger by a Cotter pin 3l, or its equivalent, passing through the trunnion 2l beneath the stop 23.

After the -desired lnumber of rafters are in place the tank top 32 is laid thereon With its edges projecting over or on to the upper edge of the tank. Generall in tanks of this character a peaked cover is placed thereon to shed rain Water or otherwise `protect the tank against damage by the elements.v

Of course I do not Wish to be limited to the exactdetails construction as herein shown as these may be varied Within the limits of the appended claims Without departing from the spirit of my invention.

Having thus fully described my invent-ion, What I claim as new and useful is l. A structure comprising, in combina-v tion, a tank, hoops surrounding said tank and having threaded meeting ends, a sister lug for each hoop into which the threaded ends are inserted, nuts screwed on said threaded ends and engaging opposite ends of the sister lug, brackets including hangers to engage the upper edge of the tank, stir rups adjustably mounted on vthe hangers and positioned Within the tankka rafter having its ends seated inthe stirrups, and means to fasten the ends of the rafter in the stirrups.

2. A tank lug` comprising a body having an arcuate face for coaction with a tank, a bearing surface with an opening there- 'through at opposite ends ofthe body and out of alignment with each other,said body furtherv having recesses in alignment With the opening in each bearing surface and at the end of the body opposite the bearing surface with Whose opening it is in alignment and said body further having apertures between the bearing surfaces and their respective recesses to permit easv access to the inf terior of the lug. l

In testimony whereof, I have hereunto af fixed my signature.

yW'ILLIAM WV. FORD.
