Abstract: 556,210. Hose-reels. WAYNE PUMP CO. Nov. 5, 1941, No. 14294. Convention date, Nov. 18, 1940. [Class 99 (ii)] [Also in Group XVIII] Liquid-dispensing apparatus comprises a hose-reel mounted to rotate with respect to a casing with resilient means automatically to retract the hose on to the reel after supply. A supply manifold 108 is rotatably mounted on an extension 114 of a flow pipe 50, Fig. 1, and carries a spider 107 with enclosing plates 98, 100 to form a hose reel to hold the turns of a hose 132, and a retracting spring 68 is interposed between the hose reel and a fixed plate 64 which carries a cover plate 70 provided with an opening defined by guide rollers such as 88 through which the hose is drawn. The inner end of the hose is attached to a radial flow arm 106 while the outer end is provided with a nozzle 134, Fig. 2, which normally rests in a boot 136. In a modification, Fig. 4, a hose reel 196, 198 is rotatably disposed about the lower portion of a manifold 166 which is fixed at its lower end to the motor casing. Pivotally mounted on the manifold is a table 246 carrying a shoe 252 which normally receives the nozzle of the hose which is wrapped around the hose reel 196, 198 ; in this position a pawl 260, Fig. 7, is adapted to be engaged by a projection 258 on a lever 214 rotatably mounted on the manifold and a lock may be applied between the nozzle and the lever 214, the nozzle being also locked by a pin 266 pressed upwardly by a cam 263 on the lever 214, Fig. 7a, to engage the trigger guard. A rotatable casing 238, 240 surrounds the hose reel 196, 198, and a retracting spring is interposed between the plate 238 and the manifold radial supply arm 188 to which the inner end of the hose is attached. In a further modification the tension of the hose reel spring is adjustable. A hose casing 434, Fig. 13, surrounds the hose reel 468, 470 and is provided with a rotatably adjustable latch plate 436 which carries a rotatable ring 454 to which one end of the retracting spring 458 is attached, the other end being attached to a stud 462 fixed to the reel hub 464. A pivoted latch 440 is provided on the plate to engage notches 456 in the ring, so that rotation of the ring relatively to the plate 436 regulates the tension of the spring. Rotatably mounted on the reel hub is a lever 512 the outer end of which is notched and provided with catch points 522, 524 and 520, Fig. 17, in different planes adapted to be engaged by ratchet plates 488, 490, Fig. 15, disposed in different planes on a pin 478 carried by the hose reel, a shoulder on the pin being adapted to engage the notch in the end of the lever 512. The pin also carries a rotatable locking member 484 shaped like a diamond the two extreme portions of which are adapted to coact with notches in a channel section plate 504 fixed to the casing plate 450. Rotation of the hose reel and interaction between the catch points on the lever 512 and the ratchets 488, 490 cause unlocking and locking of the plate 484 with the member 504.
