Specification of Letters Patent.
Patented Nov. 25, 1919.
Application filed October 8, 1917. Serial No. 195,279.
To all whom it may concern:
Be it known that I, CHARLES NUHRING, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Hose-Reels,'of which the following is a specification.
This invention relates to improvements in hose reels for supporting fire-extinguishing and similar hose in convenient position for instant use in the event of the outburst of a fire, or other occasion for employment of the hose'arising.
In. reeling hose it is customary to place the same upon the reel so that it may be wound in double folds thereon. This requires the looping of the innermost portion of the hose upon the reel, and usually it is a fixed'pin or spacer about which the looping is done.
Therefore, 1n unreeling the hose, particu-- larly if the speed of rotation of the reel is rapid, the hose is likely to become fouled, and 'difliculty experienced inreleasing the hose completely from the reel. The present invention aims to avoid this by the provisiofi of novel and eflicient means which will afiord secure anchorage for the folds but which will readily and expeditiously shed the folds when the hose is removed. I
A further object of the invention is to provide a hose reel involving in its structure novel and efficient means for choking the hose against passage of the water, notwithstanding the controlling valve may be opened before the removal of the hose from the reel, thereby permitting the flow of thewater to be turned on lmmediately on discovery of a fire or when other occasion for use of the hose may arise, and thus be available for use as soon as the choking action is relieved.
With these general objects in view, and others which will appear as. the nature of the improvements is better understood, the invention consists construction, combination and arrangement i lustrated in the accompanying drawings, and
finally pointed out in the appended claims.
In the drawings, wherein a preferred embodiment of the invention is disclosed;
Figure 1 is a vertical longitudinal seethe looped part.
substantially in the novel tional view of a hose reel constructed in accordance with the present invention, the hose being illustrated as coiled thereon;
Fig. 2 is a top plan view thereof; and
Fig. 3 is a fragmentary transverse sectional view on the line 3'3 of Fig. 1.
Referring now in detail to the accompanying drawings, the numeral 10 designates a supporting bracket designed to be clamped about a water supply pipe 11 provided with the usual controlling valve 12. A head 13 is pivotally mounted in said bracket 10 as by means of a bolt 14 or its equivalent, and to said head 13 a pair of adjustable curved supporting arms 15 are connected, as by screws 16, or their equivalent. By this connection, it is possible for the arms 15 to be adjusted relatively to each other to accommodate variations in widths of reel.
Pivotally supported between the arms 15, as by a shaft 17, is a reel 18, and arranged at the central portion or hub of the reel 18 is a plurality of spacers or pins 19 about which the hose may be coiled.
It has been stated that one of the objects of the present invention is the provision of novel means for anchoring the folds of the hose at'the central portion of the reel, which means shall permit instant shedding of the hose when the latter has been unreeled to a suflicient point to require the shedding of Tothis end a lug 20 is suitably connected to one of the flanges of the reel, and a swinging pin 21 is pivotally connected to said lug 20, as at 22 so that it may be swung across the space between the flanges ofthe reel, or moved into a position which is parallel with the flange to which it is connected, thus permitting the hose to be readily displaced from the pin 21 when sufficient pressure isexerted thereon. The position in which the hose is shed from said pin is that which the pin occupies at right angles to what is disclosed in Fig. 3, the manner of looping the hose being illustrated in Fig. 1, in which view it will be seen that the hose is wound-about the pin 21 so that double coils of the hose will be built up from the hub portion of the reel to the peripheral portion thereof as the hose is placed on the reel. The free end of the about the pin 21 is reached, whereupon pull on. the hose will swing the pin 2l to a position at right angles to that illustrated 1n Fig. 3, and the folds of the hose will thereby be shed. This precludes fouling of the hose, and enables the entire length of the hose to be displaced from the reel when occasion for use of the hose arises.
It has also been pointed out that a further novel feature of the present invention is the provision of means for choking the hose to prevent flow of the water therethrough notwithstanding the. fact that the controllmg valve 12 may be opened; The use of such choking means is also desirable to prevent passage of the water induced by the tendency of the reel to rotate when the pressure of the water'is present in the hose. To the attainment of the end mentioned, it is contemplated that the arms 15 shall be provided with forwardly extending projections 2a, to
the outer ends of which projections-a connecting bridge 25 is suitably attached. Pivotally mounted on one of said projections 24, as by means of a lug 26, is a clamping lever 27, the free end of said lever being provided with a finger 28 which fits on tothe rabbeted end 29 of the other projection 24, and is held thereon by a leaf spring detent, 30 arranged above said rabbeted end 29.
bridge 25 and the clamping lever 27 the 'outerlayers of the hose are held, and by the engagement er the spring detent 30 with the finger 28 of said lever 27 the latter exerts sufficient compressive strain on the hose or layers of the hose to preclude passage of the water therethrough. As illustrated in Fig. 1, the layers of the hose'whioh are connected to the nozzle and of that portion coupled'to the controlling valve 12 are positioned between the spring 25 and the clamping lever 27. The pressure of the spring 30, of course, is only sufficient to maintain this clamped relation, and upon pressure being applied to the nozzle to pull the same from the reel it will be seen that the lever 27 will be freed from engagement with the detent, 30, by being swung outwardly onits pivotal lug 26, whereuponthe hose may be readily unreeled and the nozzle. taken to thepointof discharge of the" water where the same may be'required.
In using the hereindescribed invention the middle; portion of the hose is looped about the -swingingpin and the pin 21 is then moved to the position shown in 'Fig. 3, or
transversely of- -the space between the-flanges Between the bridge as to exert bridge interposed between theof the reel 18. By now rotating the reel the hose will be coiled thereon until the full length thereof has been. taken up, whereupon the outermost layers which are trained over the bridge 25 may be compressed together by swinging the clamping lever 27 to the position shown in Fig. 2, in which position the finger 28 of said lever is engaged by the detent 30, thereby choking [the hose. against passage of the water. Should occasion now arise for use of. the hose the nozzle is grasped and a pull exerted thereon, this being eifective to swing the clamping lever 27 from under the spring detent 30, and'now by continuing the pull on the nozzlev the: hosewill readily unreel to. its. full length, beingasbridge interposed therebetween, a reel journaled between said arms and adapted to. receive the hose, a clamping lever associated with said connecting bridge and cooperating therewith to compress the layers of the hose when the same are. placed between said leverand said bridge, and means coacting with said clamping lever to hold the. same in locked relation to said conneotingbridge.
2. In a hose reel, the combination with a pair of supporting arms, and the reel, of aiconnecting bridge interposed between said arms, a clamping lever pivotally connected in uxtaposition to said connecting bridge, said clamping lever cooperating'with said bridge toclamp layers of the hose therebe-. tween, and means for locking said clamping lever in such relation to said connecting choking action on. the hose.
3. In a hose reel, the combination with a 1 arms, a clampinglever-pivotally connected 1 to one of said arms and adapted to swing in relation to said connecting bridge, said clamping lever cooperating withsaid' bridge to compress layers of the hose therebetween and exert a choking action thereon, and a detent carried by the other of said arms and cooperating withsaid clamping lever to hold the same in clampinlg relation to said connecting bridge.
4. In a hose rack, the combination with apair ofsu-pporting arms, and a hose reel journaled' therebetween, of a connecting fn e ends of said arms, a pivoted clamping lever mounted on one of said arms and capable of swinging movement With respect to said connecting bridge, the free end of said clamping lever being provided With a finger, the other of said supporting arms having a rabbeted portion with which said finger cooperates and interfits, and a spring detent arranged adjacent to said rabbeted portion and co operating With the finger of said clamping 10 lever to hold the latter in clamping relation to the connecting bridge.
