' 19 Claims; (Green-s6) *Onepart of the invention relates to an improvedarrangement -for hose-filling, that is to sayenclosed filling of truck tanks, In this connectionyobjects of the invention are to provide a fire-walled "device adapted to receive a hose and to conduct a solid streamof liquid from the fillinghoseto'apoint-near the bottom of the tank, andtoqsupportthis,devicein the'rnanhole in such mannerthatgit. can be lifted'out, and that it does 1 not require, modification of the manhole cover or ,interferetherewith=or, with its locking mechanism or other partscarried bythe cover. The invention employs a fire-wall reducer-or inner closure, andin the lower part of this re- 1 "5 ducer; ,which'is preferablyof a-truncated conical form or of other dished shaped extending downward in the upper part of the'tank,-a fill-tube is fixed, the top ofr this tube projecting upward for a distance in the depression formed bythe reducer and being'provi'ded with'means forooupling-a hose when the manhole cover is open. Byireason of the manner in which this tube is supported, its .hose coupling end is, accommodated belowthe'cover, in thespace between the 5 cover andthe reducein,

we The lower :end of the fill-tube is guarded by, a

and vapor while the tank is being filled, and the lower fire-screened opening .also' 'provides for draining into the tank any liquid which would otherwise be caught :the basin" of the reducer aroundithe upper endof the filling-tube. c i "Other .featurestoi the invention-will become apparent 'asithe specification proceeds. .In' the accompanying. drawings forming. part hereof I T 4 Fig. 1 is a fragmentary view in verticalzsecftion'showing the invention applied to fa"tank,,

a portionof thetank and the filling structure between .the top "and bottom being broken out;

- and "J'Fig. 2 is a sectionalplan taken on the line 2'2 The tank 2 has a'flanged'I-up manhole opening a 3 in its top; and welded to 'the-tank-shell around theopening' there is a ring orframe 4,1to which amanhole cover 5 is ,appli'ed This cover maybe of'the connection collar; These openingsvent air hinged as shown or it may be entirely removable to afford entrance by a person into the tank. The cover is shown as provided with looking d e. vices 6 below its under side to engage an S-shaped lip 7 bent inward from the top of the frame 4, and at its center the cover carries a vent device 8, which may be rotatableandconnected with the locking bars 6 so that by turning the vent device the bars can be projected or retracted. Similar features are disclosed in the application of 651 Paul S. Shield, Serial No..201,059, filed June 24, 1927, and do not require special illustration since they form no part of this invention and since other means for securing the manholecover in closed position may be employed. v

' As'in theShield application, a ring 9 of angular section is welded to the frame 4 to afford an inwardly projecting ledge 10' intermediate the height of the frame, andas in said application this ledge serves as a support on which rests the out- 7 turned periphery 11 of an inverted truncated coni ical reducer 12, but this reducer, insteadof'serving as a'funnel entrance to a broad tube for open, gravity'filling as in the said application,

here becomes a dropped support for a narrow fill- 8D:

tube l3, which is designed toconduct a solid stream of liquidfrom a filling hose, whichcan be connected with this tube when the coveris opened.

A ring 14 of channel section is preferably welded into an opening in the lower end ofthe re- 35 ducer, to constitute a part thereof,v and within this ring the fill-tube is welded. The top of the fill-tube projects for a substantial distance above the low part of the reducer and includes a'heavywalled collar 15 which is welded to the tube and is go formed with an external screwthread, onwhich j is-screwed the fixed element 16 of. a quick-acting" hose coupling; The provision thus made for the connection of a filling hose lies within'the chamber between thereducer 12 and the cover 5-'when the latter'isclosed. Any standard or suitable form of hose coupling may be employed, The

parts

9, 12 and 14 form a fire-wall extending across the manhole, from the frame 4 to the fill-tube 13, and the latter is a tubular fire-wall extending practically to the bottom of thetank, I x f As in the Shield application, one or. more vent openings 17 are formed inYtheringJQ at thee-top o'fthe reducer 12, these openings being guarded by fire screen's 181 The ring 14 is also provided withone or! more vent openings-l9, likewise cov- 'ered by fire-screens 20. This ring couldbe made i in one piece with the; reducer, but the provision of-a ,ring made of a separate piece isadvanta geous since it enables the same reducers to be carried in stock by the manufacturer to take either the narrow-fill-tube for hose filling as in the present application or a broad tube for gravity filling as in the Shield application, and the ring is also a strong part in which to locate the screened openings 19. These openings will drain into the tank any gasolene which may get into the basin of the reducer.

The lowerportion of the tube 13 enters and passes downward within a cylindrical cage 21 of much larger diameter, the upper head 22 of this cage having a flanged opening in which the tube fits frictionally, forming a slip joint. Large openings 23 are cut in the side of this cage and are covered by a fire-screen 24, which in turn is covered by a heavy protective metal mesh 25. Another opening 26 in the bottom of the cage, guarded by a fire screen 27, allows the cage to be entirely drained when the tank or a compartment thereof is emptied.

The cage is preferably secured in the lower part of the tank by bolted connections 28 between lugs welded to the sides of the cage and to the bottom of the tank, respectively. The fill-tube can therefore be withdrawn without disturbing the cage, but the latter can also be removed by taking out the bolts.

Fastenings 29 on the ledge 10 engage over the periphery of the reducer 12, so as to hold the filling structure firmly in place but in a removable manner. When the cover 5 is opened and these fastenings are released, the reducer and fill-tube can be lifted out, leaving th'e manhole unobstructed.

An indicator may be provided in the following manner:

An opening is made in the reducer at a distance from the fill-tube,and in this opening a small indicator tube 31 is welded sothat the up- 1 per end of the tube'projects into the chamber above the reducer and below the cover, while the major part of the tube extends downward a foot or so into the interior of the tank. The lower end of thisindicator tube is covered by a firescreen 32, which allows the gasolene to rise up ward in the tube as the filling of the tank proceeds but prevents flame from striking into the tank through the indicator opening.

A fioat33 in the indicator tube ascends with the liquid and causes an indicator rod 34 connected to the heat to rise upwardly above the reducer, giving ample warning to the attendant before it is necessary to cut off the supply of gasolene to" avoid overfilling. The indicator rod is guided in a hole in a cross-piece 37 at the top of the indicator tube, and this piece has an overhanging lug 35 beneath which the laterally bent end 36 of the rod can be turned to hold the rod various changes are permissible withoutdeparting from the invention as set forth in the claims.
