2 Claim.

This invention relates to a reel for water carrying hose in which; substantially as soon as the hose is started in its unwinding from the reel with a simultaneous rotation of the reel, a valve is automatically opened by operation of the reel so that water is instantly available and will continue to flow until it is-shut off manually, irrespective of how much of the hose is unwound from the reel.

The hose at its outer end; will preferably be equipped with a well-known type of nozzle which, by manual operation, may be moved to prevent flow of water from the hose, irrespective of the pressure of water that, there may be in such hose, and may be opened for greater or less flow of water at any time during orafter the unwinding of the hose. In this manner there is always a supply of water when needed, and at any length of the hose from the reel and the water may be closed on" at the end of the hose before the valve is manually closed, which manual closing of the valve, automatically opened by rotation of the reel when the hose is unwound, cantake place either before orafter the hose is rewound.

An understanding of the invention, and cf the novel structure which embodies it, may be had from the following description, taken in com nection with the accompanyingdrawings, in which.

Fig. l is an end elevation of the reel made m accordance with my invention.

Fig. 2 is an enlarged longitudinal section through the union between the fixed water sup ply pipe and the hollow tubular" axis of the reel, rotatable with the reel, and near, one end of which, the hose is connected.

Fig. 3 is a transverse vertical section and elevation substantially onthe plane of line 3.3' of Fig. 4, looking in the direction indicated, the hose being partly unwound and,

Fig. 4 is a longitudinal vertical section substantially on the plane. of line. i -4. of Fig. 1.

Like reference characters refer to like parts in the different figures of the drawings.

In the structure disclosed, a supporting frame structure is provided, including an end plate I of flat metal, of a generally triangular form, which at the apex of the, triangle is equipped; with a bearing 2. Spaced from the end I is a second generally triangular end 3 also of flat metal and of less height. Both of said ends i and 2 are suitably flanged for strength and reinforcement and, between the bottom flanges, spaced connecting bars 3a, preferably of angle form, are located and welded to the bottom flanges of the ends.

the reel plates ll (Fig. 1) but extend outwardly beyond them. And the couelbow couplings and 2. The end 3 carries abraek-et 4' of flat bar stock welded centrally of the end and extending substantially its full height, then bent to extend upwardly and inwardly toward the other end 3. terminatin in a vertical bearing section 4a (Fig. 4);

The reel includes a hollow tubular axis 5 one end portion of which is rotatably mounted in and extends through the bearing 2 and is closed at its adjacent end by a; screw plug 6. The tube 5 passes through an opening in the section 4a of bracket 4- and is rotatable therein. A short distance outwardly from said bracket section- 4a one end of a coupling '1 is screw connected. The coupling l, at itsend where it is screw connected with the tube 5, has a cup-like enlargement, and at its other end has a cup-like enlargement of greater diameter, both bein interiorly threaded. A fixed tube or pipe 8 having a disc-like enlarged head 8d at one end is inserted in the larger end of the coupling 7', into which a packing nut or gland 9 is threaded, compressing between it and such head to suitable packing I B to prevent water leakage. The pipe 8 is with a source of water supply so that from it, when the pipe 8 is unobstructed, water flows freely into the tubular axis 5 of the reel. Such tube 5 is rotatable about its longitudinal axis.

On the tubular axis member 5 of the reel, two spaced apart plates H- are mounted and are welded or otherwise secured to the tube 5 turning therewith. Such plates are of circular form At, preferably, equally spaced distances around the outer edges of the plates H, cross bars l2, terminating at each end in out- Wardly extending legs: l3, are permanently secured by weldin or equivalent permanent con.- nection; and around the outer ends of the legs l2 circular rims 4 made from metal rods are adjacent the" at the other end pling 1 located adjacent the section 4a of bracket 4- is within the adjacent end of the reel as shown in Fig. 4.

In the length of the tube 5-, a T-coupling f5 is interposed near the bearing 2", to which suitable a short length of pipe be tween them, indicated at I6, are secured, to the outer elbow of which one end of a water carryinghose I! is connected. Such hose may be Wound upon the reel by rotating it in the proper direction until its outer end of the hose is brought close to the reel. At the outer end of the hose (Fig. 1) a suitable nozzle 18 is connected which, preferably, will be of the manually closable wellknown type, and which when turned in one direction will close ofi all flow of water, and when rotated in the other direction will open so that water may freely flow to a greater or less extent, in accordance with the extent that the nozzle is opened.

In the supply pipe 8, a short distance beyond the coupling 1 and the packing nut 9, a valve housing containing a shut-off valve is located. When the valve is opened there is a free flow of water through the pipe 8 to the tubular reel axis 5, through the parts I6 and to the hose, but when it is closed the flow of water from the pipe 8 is stopped. The control valve within the valve housing 20 is off-set from the axis of the pipe 8 and is actuated by turning or rocking a shaft 20a, extending from valve housing 20. At the end of the shaft 2011. an arm 2| is secured. Such arm is located adjacent an end of the reel, on one leg l3 of which at such end of the reel, a projection I9 is mounted in the form of an L-shaped bracket preferably, the end of the arm 2|, when the valve in the housing 20 is closed, extending into the rotary path of movement of such projection 19.

With the hose fully wound upon the reel, as in Fig. 1, upon unwinding the hose by grasping its outer end and pulling thereon the reel turns and the projection 19 comes to the arm 2| to move it from its full line position in Fig. l to the dash line position shown therein. The axis of turning of the arm 20, not being coincident with the axis of the pipe 8, the projection 19, when the arm 2| has been moved to valve opening position, passes beyond the outer end of said arm 2| and the reel may then continue to be rotated in the same direction to unwind the hose to any desired extent. It is apparent, therefore, that substantially in the beginning of the hose unwinding,

and in any event as soon as the projection 19 actuates the arm 2 I, which will occur in practice during the early part of the first complete rotation of the reel, the shut-off valve is opened and water is supplied under pressure to the hose.

Therefore, by operating the nozzle l8, if it should be closed, water may be available substantially at once, and there is no necessity of unwinding the hose the desired length and thereafter operating a valve to supply the hose with water.

After the hose has been used for watering purposes and is to be rewound, the nozzle I8 is preferably closed and the arm 2| manually returned to its valve shut-01f position after the hose has been rewound to the position shown in Fig. 1. In rewinding the projection 19 will pass beyond the outer end or the arm 2|, when in its dash line position shown in Fig. 1.

While the supporting frame for the reel in the drawing is shown as mounted upon a. horizontal base, such reel may be mounted upon a vertical wall, as it frequently is mounted, the operation of the reel being the same in either position.

The structure described is very practical and useful. It is particularly useful in the case of fires where all that is required is to grasp the end of the hose and pull it out toward the fire as much or as little as may be needed, turning projecting and releasing the outlet nozzle I8, with an assurance that a supply of water under pressure will flow from the hose as soon as the nozzle is released. There will be no loss of time pulling the hose out the required amount and then returning to the reel mounting and operating the lever 2i as it is automatically operated to open the shut-off valve substantially at the beginning of unwinding the hose.

The invention is defined in the appended claims and is to be considered comprehensive of all forms of structure coming within their scope.

I claim:
