My invention relates to improvements in tampering therewith as to resist normal athose reel for fire extinguisher purposes. One tempts to tamper therewith, and at the same of its objects is to provide improved means time leave the hose and reel in condition to to reel up and store hose for fire eXtinbe readily released and unwound by a vigguisher purposes in condition to be reliably orous pull upon the hose when required for available when required, and not liable to befire purposes. My improved apparatus atcome unwound through unauthorized tampertains these and other desirable results. ing therewith. Another, object is to provide The accompanying drawing illustrates one "7, improved means to detachably attach the embodiment of my invention, in which hose to the spool or hub of the reel for the represents a metal water supply pipe, and purpose of winding the hose thereon, and at 16 a valve to control the water flow therethe same time insure the hose being readily from. A pipe section 17 leading from the detached from the reel and available for fire Valve serves as a means for attaching one purposes when required. Another object is end of the hose to the water supply pipe, and to provide an improved hose reel and means also provides a convenient means for pivotalfor locking it against rotation until required 1y mounting the hose reel 20 with reference for use, and which is readily unlocked and 0 the pipe 15 and to the building in which rendered available for use by grasping the the pipe 15 is located.

My reel 20 may be pivotally mounted relative to invention also comprises'certain details of the wall of the building in which the pipe form, and arrangement, and combination of 15 is located, but independently of the pipe components, all of which will be fully set 15, by means of an independent hose reel supforth in the description of the accompanyporting bracket attached to the wall of the ing drawing, in which; building adjacent to the valve 16. As shown, Fig. 1 is a side elevation of a reel with the the hose reel is provided with a split sleeve fire hose wound thereon ready for use. 22 which is assembled and held in place by Fig. 2 is an enlarged sectional view, taken screws 23 to encircle the pipe section 17 and on line 2+2 of Fig. 1. form a pivotal joint or journal for the hose Fig. 8 is a side elevation of the hub of the reel to rotate about the axis of the pipe secreel detached. tion' 17. q 30 Fig. 4 is a side elevation of the hub of the The hosereel comprises a skeleton metal reel detached, from the opposite side to that frame 24: pivotally attached to the pipe secshown in Fig. 3. tion' 17, or to the wall, and having a project- I In the provision of and use of hose and ing bracket 25 with yielding spring fingers hose reels for fire extinguisher purposes, it 26 between which the hose nozzle 27 is adaptis important to so wind the hose upon the ed to be forced to support the hose nozzle in reel as to make certain that when required place when not in use, and in a position to be the hose may be grasped and entirely unreadily grasped and released when required wound and detached from the reel so as to for use, and also a hose reel hub 30, which is 1 40 be available for fire extinguishing purposes, rotatably supported with reference to the and its object would be defeated if the hose metal frame 24. As shown the hub comprises became entangled with the reel and failed a substantially cylindrical hub member of to become entirely separated therefrom when wood fiber, or similar material having a rerequired for use. It frequently happens that cess or depression 31 in the face thereof, and

31 in the periphery of the hub member 30. The end plate 32 is also provided with an axial projection 38, which preferably has a cylindrical section close to the face of plate 32 to engage and journal the hub in a cylindrical perforation in one side of the frame member 24, and a polygonal section 41 outside of the frame 24 adapted to be engaged by a crank or wrench to rotate the hub 30 with reference to the frame 24 to wind the hose upon the hub 30 and within the frame member 24 as shown in Fig. 1. The hub plate 34 is attached to the hub member 30 for instance by.,screws 42, and opposite the recess 31 of the hub member 30 is provided with two cam faced projections 44, between which is located one end of a cross-bar 45. The cross-bar is pivotally attached to the projections 44 by means of a pivot pin 46. The cross-bar 45 normally occupies a position shown in full line in Fig. 2, substantially parallel with the face of the recess of hub member 30, in which position the middle portion 47 of the hose is looped over said cross-bar and affords a means by which the hose 48 may be wound upon the hub 30 and within the frame member 24. In this position, the recess 31 provides for housing the crossbar 45 and the hose loop 47 below the face of the balance of the hub member 80. In its other position the cross-bar 45 is turned upon its pivot pin 46 to a nearly right angle position to the face of the hub member 30, so as to project nearly in a radial position outwardly from the hub member 30, and in this position the cross-bar 45 is adapted to release the hose loop 47 and allow the hose loop 47 to slip freely off the free end of the crossbar 45, or preparatory to rewinding the hose upon the hub member 30, the cross-bar 45 may be turned to its radial position to insert said crossbar within the hose loop 47. The end plate 84 is preferably provided with a short inwardly projecting hub 50. The end plate 34 whether provided with a hub 50 or not is perforated and threaded to receive the threaded shank of a bolt or cap-screw 52, which is passed through a perforation 53 in the frame 24 to thereby form one of the j ournals supporting the hub 30 with reference to the frame 24, and also after the hose 48 has been wound upon the hub 30, to be further tightened by means of a wrench applied to the head 54 of the bolt 52, until the side of frame 24 is clamped and locked against rotation between the inner face of the bolt head 54 and the outer face of the end plate 34 with suflicient tension to prevent unauthorized tampering with the hose and hose reel tending to unwind the same, but not with sufiicient tension to prevent the hose being unwound from the hose reel by a vigorous pull upon the hose when required for fire pur- The direction in which the thread is spiraled upon the bolt 52 is such with reference to the direction of rotation of the hub 30 relative to the frame 24 in the act of unwinding the hose, as will tend to unscrew the bolt 52 from its threaded engagement with the end plate 84 a sufficient amount to release the tension and locking action of the bolt 52 upon the frame 24 when the hose is drawn out or unwound for fire purposes, to immediately unscrew the bolt a fraction of a turn and thereby permit the hub 30 to freely pivot and rotate relative to the frame 24 until the hose is entirely unwound from the hub 30, whereupon the loop 47 is automatically released from the bar 45, and the hose is available for use.

The apparatus herein shown and described is capable of considerable modification with in the scope of the claims without departing from the spirit of my invention.
