2-Claims. 1

This invention is concerned with a 'fluiddistributor and it is a general object of the invention to provide a simple, practical, and easily operated structure'that'can'be'used to advantage in the handling or distribution of fluids.

There are numerous "situations where fluids are delivered from a supply, as for "instance by means of a "supply pipe, and require delivery through a nozzle "or spout at various points remote from the said supply 'pipe. An example of such a situation is in the case of an oil or gasoline depot where "the liquid "to be handled is suppliedthrough apipe and is 'to'be delivered into containers or tanks on either trucks or trailers. In such a 'casethe .t'anks vary as to the height of their filling openings and the openings vary in distance 'fr'omthe supply pipe, making it advantageous to employ a delivery spout coupled to .the pipe so that it'isuniversally movable.

Structures "heretofore provided for the type of mentioned work have been more 'or less complicated "and, consequently; cumbersome, .and unless they "are accurately counterbalanced they are difficult and hazardous to operate.

'It'is ageneral object "ofthis invention to -provide a structure applicable to a supply line or fluid delivering pipe and involving an arm universallycoupled to the pipeand a 'sp'out universally ccupled 'to the arm, "the entire structure being counterbalance'dso that it issimp'le, convenient, and easy 'to operate.

Another "object of this invention is *to provide apparatus of the general character referred to wherein the parts are of simple form and are so arranged that the structure is compact and convenient to use. In the structure provided by'the present invention the-counterbalanbe employed in the construction is so con'str'aicted and located as to be most effective and it operates without materially complicating or adding to the bulk of the structure.

The various iob'jects and lieatures of my invention will be fu1-1y understood ifro'm the Rfollowing detailed description of a typical preferred *form and application :of the invention, throughout which descriptionreference. is made to theaccompanyi ng drawings, in which:

disposed pipe having fluid delivered to-it in :such

manner as to discharge -'from its upper end. :In

practice the supply pipe Afnot only forms the conductor for the fluidhandled by the apparatus of the present invention, but it forms the sole support for such apparatus.

The fluid distributing arm B of the structure provided by the present invention may, in practice, vary widely in size, form and character. In the preferred form of the invention the-arrn is a straight, rigid, tubular element-of suitable length and its ends are finished or adapted for :connection with the means C and E. In practice the-arm B may 'be "forine'd'of a simple length -of tubing or pipe and in most cases it is .most fadvantageous to make the arm straight {as shown in the drawings.

The means C couples the "arm B with the pipe A for universal movement of the arm relative to the pipe. In the preferred form of theinvention the means C involves "three tubu'l'ar -sectldns joined end to end by anti-friction means permitting the sections to rotate relative to each other. As shown in the drawings, 'the m'ea'ns C involves a base section ll] applied to the upper end of the supply pipe A, a headsection I l =applied to the inner end of the arm IB, and a heck sec- 'tion I 2 joining or extending between the secticns i0 and H.

The base section it of the means C is shown as a simple or straight tubular i-part internally threaded at its lower end "to i-receive the'threaded upper end of thesupply pipeA so that the means 3 C is joined to the pipe A by a threaded connection 13.

The neck section of the means C is an L-shaped tubular part having an inner end portion l4 forming a socket receiving the pin-like upper end portion l5 of section It. The outer end portion I6 of section I2 is at right angles to the inner end portion 14 and is shown as a socket receiving a part of the head section H.

The head section is an L-shaped tubular part the inner end portion ll of which is in the nature of a pin or male part entering the socket 16. The outer end portion [8 of the head section 2 is at right angles to the part 16 and is internally threaded to receive the threaded inner end of arm B so that the means C is joined to the arms B by a threaded connection [9.

The means C includes anti-friction coupling means 20 joining sections l0 and I2 and antifriction coupling means 2| joining sections II and I2.

The means 2!! coupling sections I6 and I2 includes rows of balls 23 in registering grooves 24 in the parts l4 and 5. The balls are introduced into position through a suitable opening 25 normally closed by a plug 26. Through the construction just described the balls couple the neck section 12 with the base section [ii for free relative rotation between the sections and yet the sections are effectively held together against separation. In practice it is desirable to provide sealing means or packing 21 between the sections ID and 12 to prevent leakage of fiuid between them. The means 2| involves rows of balls 28 in registering grooves 29 in the parts 16 and ii. The balls are introduced into place through an opening normally closed by a plug 3!. A suitable packing ring 32 is preferably provided to prevent leakage between the parts 16 and i1.

With the means C constructed of sections pivotally connected in the manner just described it serves to join the arm B with the pipe A so that the arm is free to turn about the vertical axis of the pipe and is also free to swing about a horizontal axis which is normal to the vertical axis of the pipe. Through these pivotal axes the arm can be swung to face in any desired direction from the pipe A and can be tilted to extend at any desired angle from the pipe relative to a horizontal plane.

The means E universally couples the spout D with the arm B. The spout D may, in practice, vary widely in form and construction. However, ordinarily it is desirab-e that it be a simple straight rigid element such as is shown in the drawings and in the particular case illustrated the spout is open at its outer or discharge end 35 and has its inner end coupled to the means E.

The means E preferably involves four tubular sections and anti-friction means couplin the sections for relative rotation. The particular form of the invention illustrated involves a base section 36 applied to the outer end of arm B, a head section 31, a spout section 38 joined to the spout D and coupled to the section 31, and a neck section 39 connecting sections 31 and 36.

The base section 36 is shown as a simple straight tubular part internally threaded at its inner end to receive the threaded outer end of arm 13 so that the means C is coupled to the arm by a threaded connection 43.

The neck section 39 of means E is an L-shaped tubular element with an inner end part G2 in the form of a socket receiving the outer end portion 43 of section 36. The outer end portion 44 of neck section 39 is at right angles to part 42 and is in the nature of a socket receiving the pin-like inner end portion of section 31. The head section 31 in this form of the invention is an L-shaped tubular part with its inner end in the form of the pin entered in the socket portion 44 of section 39. The outer end part 46 of section 31 is at right angles to part 45 and is in the nature of a socket receiving the inner end portion $1 of the spout section 38.

The spout section 38 is preferably a simple, tubular part with its inner end portion 41 received in the socket part 46 of section 31 while its outer end portion 48 is internally threaded receiving the threaded inner end of spout D so that the spout and means E are joined by a threaded connection 49.

Anti-friction coupling means 50 joins sections 36 and 39 of means E while anti-friction coupling means 51 joins sections 31 and 39 of means E while anti-friction means 52 joins sections 3'! and 38 of means E.

The several anti-friction coupling means just referred to may be alike in form and construction, in which case each involves rows of balls 63 in registering grooves 6| in the connected parts and the outermost part has an opening 62 through which the balls are arranged in place and the opening 62 is normally closed by a plug 63. Further, it is to be understood that adjoining sections of the means E may be packed or sealed against leakage by means of packing or sealing rings 65.

The counterbalancing means E provided by the present invention involves, generally, a stem 13 coupled to the means C by a suitably connecting means 1|, a weight W and means 12 adjustably setting the weight on the stem 1!].

The stem 10 is preferably a straight, rigid rod or bar having a shank portion 15 and an extension 16 on which the weight W is carried. The means 1| coupling the stem and means C involves a threaded end 11 on the shank 15 engaged in a socket 18 provided in a boss 19 formed on the head section 1! of means C. In accordance with the preferred arrangement the boss 19 is integrally formed on the exterior of head section I so that the socket 18 is concentric with the arm B carried by the head section I l From Figs. 1 and 3 of the drawings it will be observed that the means 11 coupled the stem 16 with the head section II so that the stem projects from the head in a direction opposite to that in which the arm B projects from the head section.

The extension 16 of the stem is preferably polygonal in cross sectional configuration and, in practice, may be an integral continuation of the shank part 15.

moved to any desired position along the stem section or portion 16. The means 12 adjustably setting the weight on the stem preferably involves collars B2 on the stem extension 16 and set screws 83 carried by the collars and engaging the stem to set the collars against axial movement thereon. In the preferred arrangement there are two collars, one at the inner end of 7 the weight and the other at the outer end of the weight. When the weight sections have been located at the desired point along the stem section 16 the collars 82 are arranged immediately adjacent the end Weight sections and the set screws 83 are made tight thus setting the weight in fixed position on the stem.

From the foregoing description it will be apparent that the present invention provides a spout D universally coupled to the supply pipe A so that it can be moved in any desired direction throughout a very wide range. It is to be observed that through the construction provided by the present invention the desired movement of the spout is gained with a minimum number of parts and the parts provided by the present invention are simple, compact, freely working parts which make the structure highly desirable in practice.

It is to be observed that through the present invention the weight of the arm, the means E and the spout D may be accurately counterbalanced by suitable location of the weight W on the stem "NJ and when the structure is properly adjusted the spout D, even though the arm may be long and the parts heavy or of sturdy construction, may be easily moved to any position throughout its range of movement.

Having described only a typical preferred form and application of my invention, I do not wish to be limited or restricted to the specific details herein set forth, but wish to reserve to myself any variations or modifications that may appear to those skilled in the art and fall within the scope of the following claims:
