HOSE-REEL.

SPECIFICATION forming part of Letters Patent NO. 613,515, dated November 1, 1898.

Application filed January 8, 1898. Serial No. 666,055. (No model.)

To all whom, it may concern:

Be it known that I, HENRY J. M. HOWARD, a citizen of the United States, residing at Washington, in the District of Columbia, have invented a new and useful Hose-Reel, of which the following is a specification.

My invention relates to hose-reels, and more particularly to that class of hose-reels which are adapted to be secured in fixed po sitions in buildings in connection with watersupply pipes.

In hose-reels of this class as heretofore constructed numerous difficulties have been encountered which I have endeavored to overcome in the reel herein described and claimed.

One of the greatest difficulties encountered in hose-reels of this class is the liability of leakage at the stuffing-boxes considered necessary in such constructions. Usually any attempt to screw up the stuffing-box sufficiently tight to prevent leakage under extra heavy pressure of water has resulted in too great friction in the operation of the reel. As is well known, the pressure of water from mains of cities or other supply varies to a considerable extent and a stuffing-box made sufficiently tight for ordinary pressure will leak when the pressure is increased.

A special object of my invention is to overcome this difficulty by constructing a hosereel with a compensating hub and stuffingbox so arranged that any increase of pressure of water in the'main will cause the pressure of the gland on the packing in the stuffing-box to be increased, and vice versa,

so that the tightness of the packing will al-' ways be regulated by the pressure of the water.

Further objects of my invention are to provide improved protection for the hose when wound on the reel, to provide for the easy after fully described and afterward specifically pointed out in the appended claims.

In order to enable others skilled in the art to which my invention mostnearly appertains to make and use the same, I will now proceed to describe its construction and operation, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 is a perspective view illustrating a hose-reel constructed in accordance with my invention connected with a stand-pipe. Fig. 2 is a central vertical sectional view through the same on the line 2 2 of Fig. 5, the stand pipe and branch being shown in side elevation. Fig. 3 is a detail perspective view illustrating the unreeling-guide. Fig. 4 is a detail perspective view of the hub. Fig. 5 is a horizontal sectional view through the hub, showing the hose attached and coiled on the lower plate of the reel. Fig. 6 is a view in side elevation illustrating another application of my improved form of reel. Fig. 7 is a similar view illustrating another application of my improved compensating stuffingbox.

Like numerals of reference mark the same parts wherever they occur in the various figures of the drawings. 1

Referring to the drawings by numerals, 10 indicates a stand pipe, in which may be placed a T-coupling 11, from which extends a lateral branch 12, with a valve 13 therein and an elbow 14 at its outer end, forming a connection with a vertical branch 15, which is provided with a ring-flange 16, vertical slots 17 for the passage of the water, and a closed upper end 18.

19 indicates the reel=hub, the central portion of which is substantially globular in form,

while exteriorly-threaded

tubular extensions

20 and 21 are provided at the top and bottom thereof. One side of the central globular portion is flattened, as at 22, and from this flattened portion projects a nozzle 23, upon which the inner end of the hose 24. is permanently threaded. The upper tubular extension 20 has an interior diameter to fit upon the upper portion of the supporting-pipe 15, while the lower tubular extension '21 is of a diameter to fit the ring-flange 16, a shoulder being formed to rest upon the ring-flange, which serves as the support of the whole reel. An annular space is thus formed below the ring-flange between the pipe 15 and the lower extension 21 of the hub, in which is placed a packing-ring 26, below which is a gland 27, inelosed in a cap 28, fitted around pipe 15, and threaded upon the outside of the extension 21 of the hub. Around the upper end of the hub, at the point of junction of the main body thereof with its upper extension 20, is formed a shoulder 29, and upon the threaded exterior of said extension is fitted a cap 30. The hub is also provided with annular downwardly and outwardly extending flanges 31 and 32, and to these flanges are bolted, respectively, the upper and lower i11verted-conical-

shaped plates

33 and 34 of the reel, the plate 33 being bolted to the under side of flange 31 and the plate 34 to the upper side of the flange 32. The plate 33 covers the hose coiled in the reel, and the plate 34 supports it, the latter being perforated or of skeleton formation to lighten the reel. A spirally-arranged row of pins connects the two plates at a short distance from the hub, beginning with pin 35, Which is located at a proper point to permit the hose 24 to be bent around it without kinking it, and the last pin 37 being located a distance greater from the hub than the first pin by about the thickness of the hose when coiled, as is clearly shown in Fig. 5.

38 indicates a ring which fits loosely around the tubular extension 20 of the hub, resting upon the shoulder 29 and between it and the cap 30. From this ring extends an arm 39, lying above the surface of the plate 33 and supported to move thereon by means of a roller 40, journaled in arms 41, projecting laterally from the arm 39. The arm 39 at the edge of the plate 33 is bent downward and forked, the

prongs

42 and 43 thereof standing vertically across the space between the outer edges of the

plates

33 and 34 and provided with

rollers

44 and 45. The hose 24 passes between these rollers and is provided at its outer end with the usual hose pipe or nozzle 46.

From the foregoing description the construction of my invention will be apparent, and its operation maybe described as follows: The hose being coiled upon the reel with its end projecting from the side thereof between the

rollers

44 and 45, it may be unwound from the reel in any direction by simply pulling the hose in the desired direction. The pull 011 the hose will carry the

rollers

44 and 45 around until they are in the direction in which the hose is to be carried, when the reel will turn freely and permit its coils to be unwound, the hose passing between the rollers, which do not revolve with the reel, but simply rotate on their own axes, the ring at the inner end of their supporting-arm rotating freely on the hub of the reel. The valve 13 having been opened prior to beginning to unwind the hose, the water will pass freely from the stand-pipe through the lateral and vertical branches and the hub and its nozzle into and through the hose and may be thrown upon the fire when the whole or any portion of the hose has been unwound by simply opening the valve in the hose-pipe.

The normal tendency of the water-pressure when admitted into the hub will be to raise it 01f. its support on the ringflange 16, and this tendency of the hub to raise will exert an upward pressure on the packing ring 26 through the medium of the gland 27, which rests upon the cap 28, threaded to the hub 19. By this arrangement any excess of pressure of water will give a corresponding increase in the pressure of the gland 27 against the pack ing-ring, thus accommodating the spread of the packing-ring and the tightness of the stuffing-box to the increased pressure. This feature of my invention is shown in Figs. 6 and 7 as applied to reels mounted upon the outer end of the lateral branch pipe 12. In the application illustrated in Fig. 6 the

plates

47 and 48, which form the body of the reel, are shaped substantially the same as the

plates

33 and 34 hereinbefore described, and are arranged on a horizontal instead of a vertical axis. In Fig. 7 the

plates

49 and 50 are mounted on a horizontal axis, as in Fig. 6, but are flat. These two figures are merely to show that the compensating stuffing-box can be applied otherwise than in Figs. 1 and 2.

By arranging the

plates

33 and 34 in the form shown in Figs. 1 and 2 the hose will pass on and oil the reel with much less tendency to kink than would be the case if these plates were in horizontal planes, the natural direction which the hose will take from the floor to the reel being almost a straight line in continuation of the direction of any radius of these plates.

By arranging the flanges 31 and 32 in the manner shown and bolting the plates to the inside thereof I provide a smooth interior surface whereby any tendency to tear the hose or interrupt it from reeling or nnreeling is obviated.

The furtheradvantage of the conical shape of the plates is that when the hose is entirely wound upon the reel there will be a continuous passage through the hose from its inner end to its nozzle, such passage having a slight downward inclination, so that the water will drip from the inside of the hose, leaving it entirely dry.

The advantage attending the operation of my guard arm and fingers has been fully described hereinbefore, as has also the advantage attending the use of the pins between the plates upon which to wind the hose, and while I have illustrated and described what I consider to be the best means for applying my invention I do not wish to be understood as restricting myself to the exact forms and arrangements shown.

Many changes and variations therefrom might be made without departing from the spirit of my invention. For instance, my improved reel might be attached to the lower end of the vertical branch pipe depending downward from the lateral branch 12 instead of rising therefrom, the necessary changes to make this application of the invention being obvious.

Having thus fully described myinvention,

what I claim as new, and desire to secure by Letters Patent of the United States, is-

1. The combination in'a hose-reel, of a hub, plates extending laterally therefrom between which the hose is wound, a ring upon the upper end of the hub, an arm projecting radially therefrom and provided with downwardly-extending, forked arms, crossing the outer space between the plates, and rollers on said forked arms, substantially as described.

2. The combination in a hose-reel, of a-vertical axis, a hub mounted thereon, and a pair of parallel, conical-shaped plates extending laterally and downwardly from said hub, between which plates the hose is to be coiled, substantially as described.
