6 Claims.

my invention to provide an apparatus of the" 10 character described in which the reel may be caused to automatically rewind the hose thereon when such hose or like flexible conduit is no longer needed. It is a further object of my invention to provide a hose reel of the character described 15 in which the retractile effect of the reel may be arrested at points of retraction of the hose so that the hose may be employed without having the reel tension exerted thereon. It i a further object of my invention to provide a structure of 20 the character described which shall beextremely light and yet durable to withstand the rough usage to which apparatus of this character is usually subjected. Other objects of my invention will appear as the description proceeds.

To the accomplishment of the foregoing and related ends, said invention then consists of the means hereinafter fully described and particularly pointed out in the claims.

The annexed drawing and the following description set forth in detail certain mechanism embodying the invention, such disclosed means constituting,however, but one of various mechanical forms in which the principle of the invention may be used.

In said annexed drawing:

' Figure 1 is aside elevational view of a hose reel constructed in accordance with the principles of my invention; Figure 2 is aftransverse, part sectional, part end elevational view of the ap-. paratus illustrated in Figure 1, taken on a plane substantially indicated by the line 2-2; Figure '3 is a fragmentary, part sectional, part side ele- .vational'view of the apparatus, as illustrated in 'Figure 2, taken on a-plane substantially indicated by the line 3-3; and Figure 1 is a fragmentary, part sectional, part elevational view of a portion of the apparatus illustrated in, Figure 1,

, taken on a plane substantially indicated bythe line H. Y y

50 Referring now more specifically to the draw- 1 ing and more especially to Figures 1 and 2 the hosereel comprising my invention includesia base frame, generally indicated at 1, which has upwardly projecting laterally-spaced standards 2 and 3, which are preferablyformed integrally.

(Cl. 242-86) I with the base although any usual method may -be' employed for fabricating this base structure of the reel. 7 The standards 2 and 3, at their upper ends, rotatably support an axle 4, the construction of 5 which will be presently'given in greater detail.

Secured to the axle 4 and'rotatable therewith is a spider 6 and a peripheral hose or flexible conduit receiving flanged portion, generally indicated at 7, which, as most clearly illustrated in Figure 2, is formed of axially spaced flanges 8 and 9.

One end 10 of the axle 4 extending through the supporting bearing on the upper end' of the standard 3 is hollow and incommum'cation with a" conduit 11 to'which the inner end 12 of the hose 13 15 is secured. The outer end 14 of the hose 13 passes through a bracket 15, which provided with a plurality ofrollers 16 which permit the hose to move through such bracket without subjecting the same to undue wear. The end of the hose carries a stop member 1'7 resiliently supported by a spring 18 on a nut 19 threaded onto the nipple 20 on the end of the hose. nguide bar 21 is provided to insure that the hose will properly run into the space between theflanges 8 and 9 01' II the reel as the reel is rotated to wind the hose thereon.

Fluid, either liquid or gaseous, may be continuously supplied under pressure to the hose by means of a swivel coupling, generally indicated 80 at 22,which connects a supply conduit 23 to the hollow terminal 10 of the axle 4. The specific construction of i this swivel coupling forms no part of this invention and hence, has not been illustrated in'detail and accordingly, will not be further described. p

The supporting frame for the reel, more "specifically, the standard 2, carriesv a spring casing, generally indicated at -24, which encloses aclock spring which has its outer end secured to 40 such casing or associated structure and its inner Tend secured to the hub 5 of the reel and is under sufilcient tension so as to, at all times, urge the reel in a counter-clockwise direction, as 'viewed Figure 1 and with sufi'icient force to'wind the hose thereon and maintain the stop 1'7 in engagement with the bracket 15. 5

In order to lock the reel against rotation while the hose is in use and after predetermined lengths of such hose haveibeen withdrawn from the reel,

so that thehose will not be under tension and interfere with its use, I provide a latch construction of unusual simplicity} and extreme durability, the formof construe on of which will now be explained.

The bearing member associated with the standard 3 or more specifically, the upper end of such standard, has secured thereto a cam block 25 which, as most clearly illustrated in Figura 1 and 3, is substantially circular in form and provided with a cut-away portion so as to provide a shoulder 26 lying substantially on a horizontal plane on the right side of such cam block as viewed in these figures. w

The spider or reel proper and more specifically, one of the spokes 6 thereof, has rotatably mounted thereon a latch member 2'7. In order to reinforce the spoke carrying the latch 27 and in addition, to provide a rigid abutment for the latch when in its engaged position, a brace member 28 extends chordal-wise between the spoke 6 carrying-the latch and the inner periphery of the reel body. This brace member is provided with a laterally projecting abutment 29, as most clearly illustrated in Figure 4, on which the rear face 30 of the latch 27 is adapted to seat.

The operation of this latch may be briefly described by having reference' to Figures 1, 3 and 4.-

Assuming that the latch occupies the position illustrated in Figure land it is desiredto withdraw the hose 13 for a distance sufiicient to reach the point of use, as the hose is withdrawn, the reel will be rotated in a clockwise direction and the latch 27 carried therewith. After the reel has rotated through a central angle of approximately 90, the latch will have dropped to the position illustrated in Figure 3. A further withdrawal of the hose effecting a further clockwise rotation of the reel will cause the latch 2'7 to be also rotated about the axis of the reel. As the latch 27 moves to the position which may be termed ten oclock on Figure 3, the rear face 30 of the latch will ride on the outer periphery of the cam 25 and will continue to ride on the cam until the spoke carrying the latch moves to the three oclock position illustrated in Figure'3,

whereupon, the latch will drop behind theprojection 26 and occupy the position illustrated in Figure l. The tension on the hose can then be relieved and the latch will prevent the clockspring from tending to wind up the reel' so that the hose may be used without having any tension exerted thereon. It is to be noted, of course, that the reel might be rotated for a further complete revolution, whereuopn the operation of the latch would be, as above described, to hold the reel in this further rotated position.

After the reel has become latched in the above defined manner, in order to unlatch the same and permit the spring to again wind up the hose,

it is only necessary that the hose be further with drawn to efiect a clockwise rotation of the spoke carryingthe latch from the three o'clock to approximately the six oclock position, as viewed in Figures 1 and 3, whereupon, the latch will drop to the position illustrated in Figure 3 so that the tension on the hose may be relieved and the spring permitted to rotate the reelin a counter-clockwise direction and during such rotation, the latch will not interfere with the winding of the reel.

From the above description of the construction and operation of the latch, it will be apparent that the same is very simple and effective in its operation and constructed in'a manner so that the latch may carry the stress to which it is subjected withoutthe possibility of failure of itselI or any of the associated parts.

The above described form of reel construction will preferably have incorporated therein a common form or centrifugal brake which has not been illustrated in the drawing but which'will prevent the spring from rewinding the hose at a too rapid rate which might result in the destruction or excessive wear of the hose or parts of the reel.

As most clearly illustrated in Figure 2, the cam block 25 is held against rotation by a bolt 25a which passes through the standard 3 and terminally thereadably engages .a threaded aperture in the cam block. As most clearly illustrated in Figure l, the cam block 25 is provided with two other circumferentially spaced threaded apertures 25' and 25", so that by means of the bolt 25a the cam bloclpmay be secured to the stand in any one of three selected positions. This provision is made so that the cam block may be supported in proper position with the notch 26 on a horizontal plane whether the stand 1 be secured to a flat horizontal plane, a vertical plane or the under side of the horizontal plane such as a ceiling.

Other modes of applying the principle of my invention may be employed instead of the one exv plained, changebeingmade as regards the mecha nism herein disclosed, provided the means stated by any of the following claims or the equivalent of such stated means be employed.

1 therefore particularly point out and distinctly claim as my invention:
