Stops H2 slidably received on the rods 98, adjacent the outer ends thereof, are adjustable on the rods 98 to limit the sliding movement of the rods 98 relative to the

blocks

6 and 48.

'11; Actuatz'ng means for clutch operating rods Means is provided for actuating the rods as and 98 as the spooling mechanism '36 is moved longitudinally on the shaft 26 and toward the ends ,of the shaft 26. This actuating means includes a pair of end members or circular plates land I I6 having hub portions that are keyed nerasto permit the end plates lid and II 6 to be rotated a quarter of a turn relative to the shaft 26 before the same are keyed to the shaft 26; this may be accomplished by providing a single. lug in the hub of .each ring H4 and H6 and by providing four equally spaced lug receiving recesses in each end of the shaft 26. By such a'construction the end plates i I 4 and H6 may be- -retained ina selected rotated position relative to the shaft 26. g

- Since both of the end plates H4 and I I6 are similar in construction,'hence a description for one will suffice for. both. For the purpose of ekplanatiodfit will be assumed that the end plate" I I6 is divided :into four equal areas by a pair of diametrical lines that'intersect each other at right angles, at the endsof one of the lines there is provided a cam I I8 and an arcuate recess 01 notch I26 and at the ends of the remaining of the lines is provided a cam-I22 and an arcuatenotch I24. '1

The cams-1w and 122 are disposed adjacent eachother and are disposed diametrically from the recesses I26 and I24respectively.

' "Ifhefunc'tion of these cams and notches will b'e described in detail in the operation of the instant invention, but briefly it may be stated that the same. cooperate with the rollers at the endsof the operating rods during sliding movement of the' operating 'rods.

:- 7: .3 Spoolsupport:

n order' fto prevent the entire weight of the sp qoli ng mechanismfrombeing supported on the shaft26g'there is provided a guide bar I26 that is mountedbetween the upper members I 28 of the j Q v Slid'jably mounted on the guide bar I 26, is a bearing 136 that is suitably secured to blocks 46 f'flose guiding means v ecuredtoand depending from the spooling mechanism 36,'by-any suitable means, is a plurality ofrrollers includinga pair of spaced substantiallyyertica1 rollers I92, an uppersubstanti allyjhcriggntal rcller I44 "and arlower substantially horizontal roller I46. The rollers are mounted for rotation and are arranged to provide a substantially rectangular opening through which the hose I48 is extended.

Further means is provided tor guiding the hose and this means consists of an idler drum or roller I50 that is journaled for rotation on the upper members I28. The idler drum I50 is disposed in a substantially horizontal position. opposes the rollers I42 and is disposed above the central portion of the drum I4.

. H ose. coupling means Embracing one end of the shaft I8, is an inner sleeve I52 that is surrounded by an outer sleeve I54. The outer sleeve I54 is provided with a pair of lateral projections I56.

Receivably engaging the internally threaded socket I58 provided in one end of the shaft I8, is a threaded sleeve I60 having an enlarged head portion I62 that is received in a socket member I64. This socket member I64 receivably engages a fluid supply conduit I 68 and an end plate I68 is removably secured to the socket member I64.

A plurality of connecting rods I10 extend between and are removably secured to the plates I56 and I68 and one of these rods forms a guide for a slidable keeper I 12 having an opening or slot I14.

The socket member "54' is externally threaded and receivably engages a packing. nut I16. having a plurality of circumferentially spaced, radially extending arms I18 projecting therefrom for pcsitioning in the opening I14 to hold the nut I'I6 against rotation.

A look nut I80 threaded on the sleeve I60 abuts a washer I82 about the shaft. I8 and urges the same, toward the sleeves I52 and I54 as shown best in Figure 7 of the drawings.

One flange of the drum I4 is provided with an opening I84 that receives one threaded end I86 of the hose I48, and the end I86 is receivably engaged in a threaded socket I88 provided in the shaft I8 and communicates with a longitudinal passage I90 in the shaft I8.

Obviously, the above described hose coupling rotates with the drum I4 and, a fluid from a suitable source passes through the conduit [66, sleeve I60, passage I90 and hence into, the hose I48.

Means is provided for connecting, the shafts I8 and 26 so that the drum I4 and shaft 26 will. be rotated together and in the same direction. This means comprises a pair of pulleys I92 and I94 that are keyed on the shafts I8. and 2,6, respec tively, and which are connected by an endless belt I96. Obviously, other means could be utilized for this purpose such as gears, reduction gearing, multiple-pulleys or the like.

It should be noted that the shaft I8 or the shaft 26 may be suitably connected to a motor or other source of power whereby the same will be driven. It is preferred that a reversible motor be employed so that the shaft 26 may rotate in either a clockwise direction or counter-clockwise direction depending on whether the hose is to be wound upon the drum I4- or unwound from the drum I4.

Winding operation Reference is now directed more particularly to Figure for the operationof the spooling mechanism.. It will be understood that the shaft. 26. in rotating in a counter-clockwise direction and: spooling mechanism. 30. is moving longitudinally upon the shaft 26, iromright to; left asshowniin this figure since the clutch pins 64 are received in the recesses 38 in. the end plate 38, and that the roller 92 is in its outermost position, the roller 94 is in its innermost position. the roller I08 is in its innermost position, and the roller I I0 is in its outermost position.

.As the spooling mechanism 30, including the

clutch members

32 and 34, moves toward the end plate I I6, the roller 92 will come to the edge of the notch I20.

The shaft 26 and end, members I I4 and I I6 are stillturning counter-clockwise and roller 92 bears against. the inner face of end members H6 and starts. rolling imparting a rightward movement of the rod 86 and disengaging the clutch plate 62 from the end plate 38 and moving the rod 98 and roller I88 leftward until the. roller I08 also engages and rolls on the inner face of the end member I I6. When in this latest. position, the mechanism 90. is arrested and inv a neutral position for quarter pause.

Shaft 26 and the end members I I4 and I I6 still rotating in a counter-clockwise direction, cam I22 engages the roller 62' and urges the rod 86 to the right to engage clutch plate 62 with end plate 38 while rod 98 moves leftward and the roller I08 is received in notch I24.

It will be noted that the same rod that disengages the clutch plate 62 from end plate 98 also engages the clutch plate 02 with the end plate 36.

The above operation is repeated with rod 86 and rod 98 with end member II4 still turning counter-clockwise with roller 94 missing notch I20 and engaging, cam I22 and roller H9 being received in notch I24 as the mechanism moves from left to right on the screw 26.

When shaft 26 and end members II4 and H6 are rotating in a clockwise. direction, rod 98 now accomplishes the indexing with roller I08 missing the edge of notch I24 and cam I I8 comes around to engage the roller I98. Roller 92 is received in notch I20 of end member II6 and rod 98 and roller IIO are now in position for return to end member II4, roller IIO to notch I24 and cam II8 comes around to engage same and roller 94 goes in notch I20 of end member II4.

' Unwindind operation Now since the mechanism 30 may be situated uponthe shaft 20 for movement toward one of the end members with the roller or one of the rods 86 inwardly so that the same could not engage the end member that the mechanism 30 is approaching, it is evident that one of the rollers on one of the rods 96 will then engage the cam II8 on the end member that the mechanism is approaching to move the

rods

86 and 98 in opposite directions whereupon the rollers on the rods 98 will always engage the cam II8 on the end members to move the rods 86 and in such instances the rollers on the rods 86 will enter the notches I20 in the end members.

To further emphasize the operation of the present invention, it is noted that when the roller 92 is in its outer position the roller H0 is also in its outer position and that the rollers 94 and I08 will be in their innermost positions, so that regardless" of the longitudinal directional movement of the mechanism 30, one roller will always engage a cam on the end members thus permitting automatic operation of the spooling mechanism for both winding and unwinding hose or such other material on the'drum I4.

it is. further noted that. when one ofthe rollers 7 of one'of the operating rods, for example, 'roller 92, is engaged with a cam of one of the end members, one of the rollers of the remaining of the operating rods, for example roller I08, is entering the notch in the one of said end members.

It is noted, that when the shaft 26 is turning counterclockwise and the driving means is stopped and the mechanism 30 is arrested at substantially the center of shaft 26 and the shaft 26' is then rotated clockwise, the mechanism 30 will return to the same end member from which it left prior to the stopping of the machine and the same rod and roller that engaged the end member previously, will then disengage the end memher and the other rod will ngage the end member.

When mechanism 30 is at either end and in pausing position, machine can be stopped and started counterclockwise, and rod 86 and earn 122 will engage and when starter clockwise rod 98 and cam H8 will perform the engaging with the end member.

When the mechanism 30 is in pausing position,

rollers

92, 94, I08 and H are extended toward the end members equal amounts. r
