IMPROVEMENT. IN HOSE-REELS.

Specification forming part of Letters Patent No. 140,784., dated July 15, 1873; application filed June 24, 1873.

To all whom it may concern:

Be it known that I, THOMAS J. MAYALL, of Boston, Suffolk county, Massachusetts, have invented certain new and useful Improvements in Hose-Reels, of which the following is a specification:

The reel in which my invention is com prised is designed with special reference to its use in factories, stores, and other like establishments. It will, however, be found available for many other uses. The characteristic features of the hose-reelin g apparatus in which my inventionis comprised consists in winding the hose, in a volute around a center or axis, in layers or folds, each of which is separately supported without contact with the other layers or folds in order to keep the hosein constant readiness for use, so that even when the hose is wound up water can readily pass through it, the effect of this arran gement being that, without impeding or interfering in any way with the free delivery or discharge of the water through the hose, only so much of the hose as is actually required need be unwound, the remainder being kept wound up and out of the way.

The nature of my invention and the manner in which the same is or maybe carried into effect can best be explained by reference to the accompanying drawings, in which- Figure 1 is a side elevation, and Fig. 2 is a front elevation, of a reel adapted to carry out my invention. In each figure the hose is represented wound upon the reel and connected with the water-supply.

The essential portions of the reel consist of, first, two sets of radial arms, the one the counterpart of the other, placed at a suitable dis tance apart, and connected by a rod or its equivalent, which constitutes the axis of the reel; second, detachable cross-pins or rollers, extending across between the two sets of arms, and resting, at their ends, in slots or open bearings formed in the said radial arms. The two sets of radial arms are represented at A B 5 their axis or connecting center-rod at G; the cross-pins at 1 2 3 4. 5, &c.; the slots or open bearings at a. The axis or center rod 0 has its bearings in a suitable frame or fixed arm, D, its journals or cylindrical ends, which project beyond the arms A B, resting, for this purpose, in open bearings 12 formed in the arms D. .The slots ain the radial arms are formed as shown, those in the one set of arms being counterparts, both as to shape and position, of those in the other set. slanting in the direction represented, so that when the arms hang downwardthe cross pins or rollers, whose ends fit in the slots formed in said arms, will drop out from the said slots unless upheld by the hose. The radial arms A B in each set are represented as four in numing until about one-half of its length has beenso drawn. The roller 1 is then put in, this being opposite to the point where the nozzle-end of the hose passes out from the opening in the center-rod O; and the hose on this side of the opening is carried around or overthis roller,

as indicated in Fig. 1. Roller2 is then put in,

and the said portion of the hose is carried over it also. The point where roller 3 is located is opposite the mouth or end of the center openin g, where the other portion or half of the hose is joined-that is to say, the half of the hose between the reel and the pipe E. As soon, therefore, as roller 3 is put in, not only the hose that has been previously carried around rollers 1 and 2 is carried around this roller 3, but also the other portion of the hose, as indicated by the dotted lines at roller 3 in Fig.1. Roller 4 is then put in, and the two portions of the hose are carried over it; and so on, as respects rollers 4 5 6 7 ,&c., until the whole of the hose has been wound up.

It will be seen that 1 thus wind the hose from the center, and wind its two halves or portions at the same time and in the same direction, as

indicated in Fig. 2. Each coil remains sepa The slots are made' of the hose, and be discharged with full power and efl'ect from thehose-nozzle.

If at any time it be required to unwind the hose to enable distant parts of the room to be reached by it, all that is needed is to draw or pull on the nozzleend. This rotates the reel, and unwinds the hose from both ends; and, in proportion as the hose leaves the cross pins or rollers, and the radial arms, in which said rollers are carried, reach their lowermost position, the rollers thus released will drop, of their own weight, from their slanting slots or open bearings, and thus leave the under coil of hose free. Even if they should not thus readily drop the unwinding of the hose would have the efl'ect of forcing them out, as will b readily understood.

The hoseis attached to the pipe E by a screwcoupling, a. other position is readily efi'ected by unscrewing the coupling 6, securing the ends of the hose, and lifting the reel, by the handles 0, from its resting-place in frame D.

Each set of radial arms may be encircled by a hoop, F, which, while bracing the arms, will also constitute wheels, upon which the reel can be trundled along.

The reel or apparatus above shown and described is what I consider to be, on the whole, the best form in which my invention can be embodied, inasmuch as the apparatus is convenient, easily handled, and so arranged as to wind from the center of the hose toward both ends simultaneously, thus saving time in both winding and unwinding. But the apparatus may be variously modified so long as the char- The removal of the reel to any.

acteristic feature of my invention is preserved, viz., the winding of the hose upon a revolving reel in a volute or scroll, each of the layers or folds of the coil being separately supported without contact with the other, so as to permit the free passage of water through the hose, whether the same be wound up, or wholly or partly unwound, or Whether it is in course of being wound up or unwound.

Having now described my invention, and the manner in which the same is or may be carried into effect, what I claim, and desire to secure by Letters Patent, is

1. The revolving reel for hose, constructed and arranged substantially as herein described, whereby thehose may be wound upon the same in a volute or scroll, each layer or fold of which is supported separately therein without contact with the other layers or folds, substantially as and for the purposes shown and set forth.

2. The combination of the two sets of radial arms, connected by a center-stem constituting the axis of the reel, as described, with detachable rollers or cross pins fitting and held in inclined slots or open hearings in said arms, under the arrangement and for operation substantially as shown and described.

In testimony whereof I have signed my name in the presence of two subscribing witnesses.

THOS. J. MAYALL.
