1 Olaim. (01. 299-78) The present invention relates to reels and more particularly to hose reels of the type wherein thehose remains attached to the-source of liquid. Some of the objects of the present invention 'are to provide an improved hose reel; to provicle an improved hose reel wherein the overall reel length is maintained a minimum for all conditions of use; to provide a reel assembly wherein piping connections and pipe lengths heretofore projecting beyond the confines of the reeling drum are now located within the area. bounded by such drum; and to provide other improvements as will hereinafter appear. In the accompanying drawings Fig. 1 represents a side elevation of a hose reel embodying one form of the present invention; Fig. 2 represents an end elevation of the same partly broken away; Fig. 3 represents a detail section of the spoke assembly taken on line 33 of Fig. 1: Fig. 4 represents a section on line 4-4 of Fig. 1 but on a larger scale; Fig. 5 represents a section on line 55 of Fig. 1 but on a larger scale; and Fig. 6 represents a side elevation of a portion of the reel showing a modified construction.

Referring to the drawings one form of the present invention consists of a winding drum 10 preferably in the form of a sheet metal cylinder bolted or otherwise made fast at opposite ends respectively to two rings 11 and 12 of equal diameter. The ring 11 forms the rim of a spider in the form of an integral casting including a hub 13 and radial spokes 14. The ring 12 likewise forms the rim of a second spider in the form of an integral casting including a hub 15 and spokes 16. In the case of the first spider,

. the ring 11, hub 13 and spokes 14 all lie substantially in the same plane, but in the case of the second spider, the hub 15 is out of the plane of the ring 12 so that the interconnecting spokes 16 extend radially from the hub 15 and curve laterally or axially to join the ring 12.- By this latter construction the hub 15 is brought well within the drum 10 between the two spiders so that there is an unobstructed space to the interior of the drum from the end thereof where the ring 12 is located. Thus instead of two spiders spaced by the length of a winding drum as in prior devices of the kind, the two spiders in accordance with the present invention are approximately only half the drums length apart and. thereby provide room for certain parts as will hereinafter appear without in any way weak-'- ening the general assembly.

For supporting the spiders for rotation and also providing means for delivering liquid to the hose, 9. fitting is providedin the form of a tubular -L '17 having an extension 18 co-axial with one of its branches while the other branch communicates with a discharge outlet pipe 20. This latter pipe 20 passes through an opening 21 provided in the periphery of the drum, and the arrangement is such that the outlet 22 of pipe 20 is in close proximity to the drum and positioned to discharge in a circumferential direction. The extension 18 mounts the hub 13 and is in turn mounted in a bearing 23 carried by frame members 24. The pipe 1'? mounts the hub 15 and isin turn journalled within one end of a coupling sleeve 25 which is supported and held fast by a split clamp yoke, 26 seating in a circumferential groove 27 of the sleeve 25. The opposite end of the sleeve 25 is preferably of larger bore to receive the flanged end of an intake pipe 28, and is also internally threaded to receive a packing bushing 30. Suitable packing 31 is locatedbetween the flange 32 and the bushing 30 .to prevent leakage along the joint and the constructions is that of the usual stufllng box. The threaded end 33, of the intake pipe 28 can be connected to any suitable source of liquid supply, such for example, as the elbow 34 and pipe 35 which lead to the discharge from a tank or pump as the case may be. The yoke 26 is bolted or otherwise made fast'to a bracket 36 which projects laterally from a supporting frame '85 3'7 and enters the end of the drum 10. toproperly aline the yoke 26 with the bearing sleeve 25.

In order to prevent lateral displacement of the hose and allow uniform build-up of its convolutions, a. series of radially arranged guard rods 38 extend outwardly from the periphery of each of the rings 11 and 12, and serve in the one instance to support a circular felly 40, and in'the other instance to support a like felly 41. As here shown all of the rods 38 are mounted in the same way, namely each has a threaded end 42 screwed into a tapped hole 43 in the corresponding drum ring, while the opposite end seats in a socket 44 in the corresponding felly. When all of the rods 38 are adjusted to properlyposition the two fellies 40 and 41 at the same radial distance from the axis of rotation they are made secure against displacement by tightening the respective nuts 45.

For the purpose of rewinding a hose upon the 105 reel, the extension 18 has a sprocket wheel 46 keyed or otherwise fast thereon for receiving motion by way of a driving chain 4'1 from a second sprocket wheel 48 keyed to an operating shaft 50. Suitable bearings 51 journal the shaft 110 and are respectively attached in an adjustable manner to the base members 52. In the present instance this adjustment consists of forming each of the bearings 51 integral with a plate flange 53 having slots 54 therein and also having one face provided with a row of teeth 55. A rack plate 56 is located between each flange 53 and the corresponding side frame member in position so that its teeth 57 mesh with the teeth 55. Bolts 58. pass through the respective slots 54 and transverse both the plate,

56 and the corresponding frame member to anchor the bearing in any selected position. Washers 59 coact with the flange 53 to permit the desired positive clamping of the parts'together. This construction forms means whereby the two bearings 51 can be alined and adjusted to tighten or loosen the chain 4'7 whenever necessary. A clutch part 60 and cooperating clutch handle 61 provide means for rotating the shaft 50 to produce a winding operation.

As a means for maintaining a suflicient friction or braking action upon the drum 10 whereby there is no over-running of the hose,a band 62 passes about drum 10 in contact therewith and has one end made fast to a bracket 63 attached to the frame 37 while the opposite end passes through a bracket 64 and.- is maintained in taut condition by a coil spring 65 compressed between the bracket 64 and a follower 66 which is held adjusted by a nut 6'7 on the threaded end of the band 62. The bracket 64 is fast to one of the frame members 37 at a convenient location. The base members 52 are interconnected by cross brace bars 69 in order to form a complete unitary supporting frame for the reel and its parts.

In the form of the invention shown in Fig. 6

, provision is made for using a drum 70 of larger diameter than one which would normally seat upon the rings Hand 12 while still using the same general assembly as heretofore described. This is accomplished by threading an additional nut '71 upon each of the rods 38 and slipping a bushing 72 over each rod 38 between the anchor nut 45 and the drum 70. These bushings '72 are all of the same length, but that length is such as will conform to the spacing necessary to properly mount the larger diameter drum in concentric relation to the rings 11 and 12. In

this modified form a drum 70 of larger diameter new forms the-winding element for the hose while the diameter of the two'fellies 40 and 41 remain the same as'heretofore described. Fellies of larger or smaller diameter can also be substituted. by merely providing rods 38 of the required length or where this is unnecessary they can be screwed into or out of the rings to correspond with the selected felly diameter.

It will now be apparent that a complete unitary assembly for reeling a hose has been devised wherein a wide'range of hose lengths can be handled by the same main parts, thus making it unnecessary to manufacture and carryin stock individual reels for each differing hose characteristic or hose length. Also by the present invention the over-all length of the reel structure is maintained at a minimum thereby making it possible to mount a reel having a maximum length of hose in a space not heretofore possible in a reel of the same capacity. Furthermore the liquid delivery conduits and associated parts are adapted for use with winding drums of diilerent diameter, so that it becomes a constant factor in a large number of possible reel combinations.

While-the reel of the present invention is a general purpose one it has also-a specific use as an assembled part of a vehicle for transporting oil in tanks for delivery to various points of use. In such vehicles the major element is the oil tank and all accessories must give way to the proper locating of such tank so that'in the case ofthe hose reel there is always a minimum of space available. More particularly this space is limited as to width so that an essential property of any reel is that it be of such a limited lengthas to fit this relatively narrow space. The reel of the present invention with its constant limited length feature for substantially all drum diameters fulfills all the requirements of such oil tank vehicle use.

While only two forms are shown in which this invention may be embodied, it is to be understood that the invention-is not limited to any specific construction, but might be applied to various forms without departing from the spirit hub surrounding and engaging the discharge pipe extension, 9. bowed spider at the other edge of the drum with an inset hub surrounding andengaging the co-axial portion of the discharge pipeat a point approximately midway of the drum, said hubs forming spaced bearings in -which the discharge pipe is rotatably mounted,

a stationary supply pipe having an extension coaxially entering. the drum, and a packed pipe coupling positioned in the drum between the inset hub'and the adjacent edge of the drum connecting the supply pipe and discharge pipe.
