FLUID CONDUCTOR AND TAKE-OFF 3 SheetsSheet Filed Dec. 28, 1955 INVENTORIS fidkezz ATTORNEYS.

United States Patent This invention relates to fluid conductors or supply lines and fluid take-01f means therefor, and more particularly to a conductor and take-off assembly for supplying pressure fluid to operate mobile and stationary machines of various kinds in factories, machine shops and the like.

One of the prime objects of the invention is to design a fluid pressure conductor and take-01f means connected thereto which is movable along the conductor without losing contact with the supply of fluid in the conductor so that pressure-operated machines such as hoists, cranes and the like may be continuously supplied, at various desired locations in the factory without necessitating the provision of a plurality of fluid reservoirs or air compressors, or the employment of long lengths of hose which would obstruct floor space. i

A further object of the invention is to provide an assembly of. the type described which eliminates the time-consuming and costly necessity of tapping into an existing supply line or conductor at a plurality of points when pressure fluid supplied machines are moved from one location to another in the factory.

Another object of the invention is to design a conductor and fluid take-off assembly of simple and practical construction which is leak-proof, and will not permit the escape and consequent loss of the pressure fluid.

A still further object of the invention is to design a pressure fluid conductor and take-off unit assembly which can be economically manufactured, and readily assembled and installed with a minimum of difliculty and expense.

Briefly, the invention comprises a normally sealed, longitudinally split conductor line formed of a resilient, deformable material in combination with a radially ported, revolvable fluid take-01f wheel which is supported so as to be movable along the line, and extends into the line to spread the splitwall thereof and provide an outlet opening at any desired point intermediate the length of said line. Certain of the ports in the wheel are in communication with the outlet opening and a passage leading to a delivery line is provided in the stationary hub of the wheel in communication with only these designated ports.

With the above and other objects in view, the present invention consists in the combination and arrangement of parts, hereinafter more fully described, illustrated in the accompanying drawings, and more particularly pointed out in the appended claims, it being understood that changes may be made in the form, size, proportion, and minor details of construction, without departing from the spirit, or sacrificing any of the advantages of the invention.

In the drawings:

Fig. 1 is a side elevational view of our novel fluid con ductor and take-01f assembly.

Fig. 2 is a transverse, sectional view taken on the line 22 of Fig. 1.

Fig. 3 is a transverse, sectional View taken on the line 3-3 of Fig. 1.

Fig. 4 is a fragmentary, sectional, plan view of our conductor, showing also the ported wheel, the wheel supporting hanger members, track and wheel being omitted.

Fig. 5 is a transverse sectional view illustrating a modified embodiment of our invention.

Fig. 6 is a side elevational view of the take-01f wheel only, a portion thereof being broken away to show the novel arrangement of the radially extending passages in the take-elf wheel.

Referring now more particularly to the accompanying drawings wherein we have shown the preferred embodiments of our invention, a letter C generally indicates our conductor which can be employed to supply any liquid or gaseous pressure medium as desired and includes an inverted, U-shaped, metallic conduit or casing 10, the free edges of which are turned inwardly as at 11 and thence terminate in spaced-apart, upwardly angled portions as at 12.

A resilient, deformable,extruded rubber liner 13 is fitted in the conduit 10 in any suitable manner, the liner having a longitudinally split lower wall including upwardly disposed, angled, converging portions 14, which extend beyond the free edges of the conduit 10 and are provided with normally abutting, enlarged sections 15 (see Fig. 2 of the drawings). Integral partitioning ribs 16 join the outer wall of the liner 13 and the outer corners of the substantially rectangular-shaped portions 15 to define a main air conducting passage 17 and side pressure equalizing chambers 18, the chambers 18 communicating with the passage 17 through ports 19 provided at longitudinally spaced intervals in the ribs 15. When the liner 13 is extruded, the sections 15 may be separated by the extrusion die or may, of course, be formed as one-piece and thence are later split to form the separable sealing sections. It is to be observed that a split depending bead 20 is provided as shown to increase the area of the sealing surfaces, and longitudinal openings 21 are provided in .the sections 15. Plugs 22 are provided for the ends of the conduit 10 and an air intake line I leads from a source of compressed air or other pressure fluid supply through the conduit into the chamber 17 asshown.

Provided at longitudinally spaced intervals on the con- Lduit 10 are reinforcing plates or brackets B which prevent .the conduit from spreading under the pressure of the fluid carried thereby and which may be employed to support the conductor 10 in a building in any suitable manner. Mounted on the sides of the brackets 22 are tracks 23, the angularly disposed legs 23a of which are slightly inclined as clearly shown in Fig. 3 of the draw- ,ings. Hanger members 24 provided with rollers 25 on their upper ends, ride on the tracks 23, and support a take-off wheel 26 as will now be further described.

As clearly shown in Fig. 3 of the drawings, the wheel 26, which is preferably of metallic construction, is removably mounted on a hub 27 formed with reduced ends 28 to which the lower end of the hangers 24 are connected, and nuts 29 are threaded on the ends of the hub 27 as shown, an outlet hose 30 leading from one end of the hub 27, all as shown in Figs. 1 and 3 of the drawings.

The wheel 26 is of suflicient diameter to extend into the conduit 10 and spread the sections 15 of the liner 13 as shown in Figs. 3 and 4 of the drawings, so that certain of the radially extending passages 31, provided in the wheel 26, are in communication with the supply chamber 17. The hub 27 of the wheel 26 is ported as at 32 to permit the passage of air from only those passages 31 which are in communication with the chamber 17 to the bore 33 which leads out the one end of the hub to the outlet line 30.

In operation, it will be seen (see Fig. 4) that a limited section of the peripheral outer rim of the wheel 26 extends into the casing 10 so that a limited number of passages 31 are open to the passage 17 in the conduit 10,

the lips of the conduit yieldingly and tightly engaging the outer periphery of the wheel to form a leak-proof joint therewith, permitting air to freely flow through the continuous passages formed by these passages 31, the port 32, and the bore33 to the outlet hose 30 without leaking to atmosphere. The pressure equalizing chambers 18 permit the remainder of the lining 13 to remain closed even under pressures of over 150 p. s. i. The ports 19 through the ribs 16 are virtually closed at the point where the lining is deformed by the wheel 26 as will be seen from an inspection of Fig. 3 of the drawings.

It is to be understood that a plurality of the take -off units, which we have described, may be employed on a given conductor line 10 and as various pressure fluid powered machines are moved to various locations, the take-off units are moved on the line 10 to supply them. Further, of course, it may be desirable in some instances to provide a T or other multiple connector fitting in place of the fitting 30a which is connected to the hub 27 to supply several machines from a single take-off unit. In Figs. 5 and 6 we have shown a modified embodiment of my invention in which the construction of the take-01f wheel is different from that of the Wheel illustrated in Figs. 14. The longitudinally extending conduit 10 as before includes portions 11 and 12' and the liner 13 includes portions 14, 15, and 16' to again form a main air conducting passage 17' and side pressure equalizing chambers 18'. Ports 19' connect the chambers 17' and 18 and plugs (not shown), of course, are provided for the ends of the conduit and a pressure fluid supply line (not shown) similarly leads into the chamber 17'. V Reinforcing plates B on the conduit 10 support tracks 23' which support the hangers 24', the latter members including rollers 25' which ride on the tracks 23'. The lower ends of the hangers 24 are formed with hearing housings 34 in which are roller bearings 35 for rotatably supporting the reduced ends 36 of the hub shaft 37 of the take-off wheel 26. Nuts 38 secure the bearings 35 in position and as will be seen, the hub 37 rotates with the wheel 26' and delivers the pressure medium through a bored passage 39 to a stationary fitting 40 which is connected toa supply hose (not shown). The wheel 26', of course, is of sufficient diameter to extend into the conduit 10 and spread the sections 15 of the liner 13 so that certain of the radially extending passages 41 provided in the wheel 26' are in communication with the supply chamber 17. The passages 41 are drilled in sufficient proximity one to the other that they intersect as shown at 4112 and at spaced intervals a passage 41 extends beyond the point of intersection as at 41b into communication with an enlarged annular header chamber 42 provided in the wheel. From the chamber 42 ports 43 extend through the hub 37 into the bored passage 39. As will be seen, check valve fittings 44 are provided in the outer end of each plassage 41 and these fittings include ball chambers 45 with balls 46 therein adapted to close the valve ports 47.

In operation, only a limited portion of the peripheral outer rim of the wheel 26' extends into the casing 10 so that only a limited number of passages 41 communicate with the supply passage 17 in the casing. The pressure of the fluid in the passage 17 forces the balls 46 in the fittings 44 in these passages off their seats to permit the passage of the fluid through the valve ports 47 into these passages, while the remaining passages 41 not in communication with the passage 17' remain tightly sealed. Since all of the passages 41 intersect the pressure fluid proceeding in through the piassages 41 which are in contact with the passage 17, forces the balls 46 in the check valves 44 in the other passages against their seats. Thus, there is no possibility of the pressure fluid leaking to atmosphere, the pressure fluid finding its way "through the annular passage 41a formed by the intersection of the passages 41 to the portions 41b of certain passages 41, thence to the chamber 42, the ports 43, and

the passage 39 to the joint or fitting 40. The one end of the hub shaft 37 extends into the fitting 40 and is rotatable therein so that the fitting may remain stationary when the wheel rotates as it is moved to a new location on the conduit 10'.

It will thus be applarent that we have perfected a pressure fluid conductor and take-01f unit assembly of novel and practical character which permits a pressure fluid powered machine to be moved to various locations in a factory or other building without losing contact with its supply source.

It is to be understood that the instant descriptive matter is intended las illustrative of the principles of the invention rather than limiting, and that various equivalent changes may be made in the various component elements of the device without departing from the spirit of the invention or the scope of the appended claims.

For example, when the term split or longitudinally split is employed in the claims the term does not necessarily mean a line which is split from one end thereof to the other, but may also mean a line which has one or more splits therein at any location or locations in its length. Further, the term fluid has reference to any liquid, gas, or material in a fluid state.
