I di ivingz di unif B ftm thereelytafixibie n'i'ember or wim'iin hose fIhereI A'ma be a simple or-plain-reel shaped flfld 'profiortibnedte roperly aecomm'ouatethe hose H being handled by the apparatus. In the drawings I have shown a reel A characterized by a hub with radially projecting flanges H at the ends of the hub. In the particular construction shown in the drawings the flange at the inner end of the reel projects radially inward to have a mounting flange l2 by which the reel is secured to the drum B, as shown in Fig. 3 of the drawings.

When the reel A is employed to carry a hose, or the like, means is provided for supplying a suitable fluid to the hose. In the case illustrated the supply means for the hose involves a fixed central fitting l3 mounted as hereinafter described to be concentric with the reel A, a delivery pipe having a section l4 entering the fitting line is wound in opposite directions onto the two drum sections, and since the drum sections are of equal or substantially equal diameter where their inner ends adjoin, the structure operates so that the loo X of the drive line does not change in length or size when the drive drum is rotating and the end portions of the drive line are 'both at or adjacent the point at which the drum sections join, as shown in Fig. 8. When the end sections of the drive line are at or near the outer ends of the two drum sections, as shown in Fig. 9, there is a maximum change in the size of the loop X for 13, and a section l5 connected to the hose H, and 1 packing means l6 establishing a fluid tight connection between the fitting l3 and pipe section M. The driving drum B is a differential drum on which are wound the end portions of a length of cable or the like. The cable which I refer to as a drive line C has both ends secured to the driving drum and is related to the driving drum so that its two end portions wind onto the drum in opposite directions. related to or carried by the driving drum so that it has the loop portion X which in the arrangement illustrated depends from or is below the drum where it extends around the pulley D. The driving drum B is made to have a differential action by forming it so that it has two end sections land 2| of different sizes or diameters, the end section 20 being considerably smaller in diameter than the section 2 l. The two sections of the drum are preferabl concentric with each other and are i joined together end to end, as shown in Fig. 3. In practice the cable carrying surfaces or periphcries of the drum sections may be plain -or they may, as I have shown in the drawings, be grooved to aid in guiding the drive line as it wraps onto the drum. Furthermore, the two

sections

20 and 2| 0f the driving drum may be varied considerably in form or shape. For instance, they may be straight cylindrical drum parts or they may be varied in diameter :at different points along their lengths. In the particular case illustrated both drum sections are shown somewhat tapered and they are related so that the large end of the small section 20 is innermost while the large end of the large section 2| is outermost.

. A feature of the present invention is the formation of the drum at the inner or adjoining ends of the sections so that the cable carrying parts of the two drum sections are equal in size or substantially equal in size where the drum sections adjoin. It is to be understood that I may vary or even reverse the pulling action, or the relative sizes of the cable carrying parts to break or counteract the overtravel that might otherwise result from the action of inertia. In the particular form of the invention illustrated I gain substantial equality in size between the'inner or adjoining ends of the drum sections by providing the large drum section 2i with a steeply tapered inner end portion 22 which corresponds in diameter with the inner end of the drum section 20 where the two drum sections are joined. Through this formation of the large drum section the last few turns of the drive cable around the drum section 2| decrease in size as they approach the inner end of the small drum section so that the innermost or last turn of the line on the large drum section is of the same diameter as the innermost turn at the inner end of the small section of the drum. It will be observed that since the drive Further, the drive line is k a given amount of movement or rotation of the drive drum, this being due to the fact that under this condition as shown in Fig. 9, one end of the line is on a rather small diameter at the outer end of the drum section 20 while the other end of the line is on a larg diameter at the outer end of the large drum section 2|.

The drive drum B that I have hereinabove described may, in practice, be mounted in any suitable manner although I prefer to mount it immediately adjacent and concentric to the reel A as shown throughout the drawings. In the case illustrated in the drawings the fi ange part [2 of the reel A is secured directly to the outer or foremost end of the small drum section 20 by bolts 24 or other suitable fastening means, so that the reel A and drum B form a rigid or continuous unit. In the preferred construction the drum B has a central hub 25 rotatably mounted on a spindle 2'6 projecting from a frame element 21. In the case illustrated the spindle 26 is a hollow or tubular spindle which is in effect integral with the frame element 21 and the fitting I3 hereinabove referred to is threaded or otherwise attached to the end of the spindle on which the drum B is rotatably mounted. The reel A may have a central hub portion 25' secured to the dense part II of the reel by bolts 24', and the hub 25' may be rotatably mounted in a bearing 26' carried by a frame element 21'. The

frame elements

21 and 21 are shown as integral parts of the frame structure 50 as will be seen in Fig. 1 of the drawings.

The cross head E carries the pulley D and serves as a connecting link betwen the drive line C and the means G. In the arrangement illustrated the cross head E is located below the drive drum B and the drive cable loops down from the drum B to extend around the pulley D carried by the cross head. The bearing or mounting means F supports the pulley D on or from the cross head E so that the pulley revolves about an axis located in a horizontal plane and is bodily rotatable within limits about a vertical axis. The cross head E moves bodily in a vertical direction and it is maintained so that it extends in a substantially horizontal direction transverse of the axis of the driving drum B. The cross head has a central or intermediate neck portion 30 which serves to offset the two side portions 3| of the head in the manner clearly shown in Fig. 5 of the drawings.

The bearing or mounting means F that I have shown in the drawings involves, generally, a split bearing block 33 that surrounds the neck portion 30 of the cross head and has its sections assembled so that it is supported for limited rotation on the ends of a vertically disposed pivot pin 34 carried by the neck 30 of the cross head. A ring 35 surrounds the sections of the bearing block 33 and a retainer plate 36 is secured to a radially projecting flange portion 31 of the bearing block so that the several parts just referred having its end portions wound in opposite directions on said portions of the drum, and means applying force to the line to rotate the drum the inner end of the largest portion of the drum having a reduced part of substantially the same diameter as the smallest portion of the drum.
