REEL.

SPECIFIGATION forming part of Letters Patent N0. 492,024, dated February 21, 1893. Application filed August 5, 1892. fierial No, 442,264. (No model.)

illustrated in the following specification-and the accompanying drawings,the novel features thereof being specified in the claims annexed to the said specification.

In the accompanying drawings representing a hose-reel embodying my improvements, Figure 1 is a side elevation. Fig. 2 is an end View. Fig. 3 is a section through the valve on the line 3-3, Fig. 4:, showing some of the parts to the left hand of said line in elevation. Fig. 4 is a longitudinal vertical section on the line 4-4, Fig. 3,-showing the valve lever and roller in elevation. Fig. 5 represents the hub of the reel and one of the reelsegments detached.

In the accompanying drawings, A represents the reel, B, the hose wound t-hereon,and C the water supply-pipe. When the hose is unwound from the reel, the reel revolves and opens a valve by which water is admitted from the supply-pipe to the hose, so that the water may be thrown onto the fire instantly. The first revolution of the reel opens the valve, so that the hose is filled with water by the time nozzle M on the end of the hose has been carried a few feet from the reel. The valve is operated by a spiral cam which revolves with the reel, being permanently attached thereto, so that there is nothing to be done in case of an alarm of fire, except to draw the hose from the reel and open the cock e in the nozzle M. The construction is such that the valve may be closed by hand and the motion of the reel in rewinding the hose thereon does not affect the valve.

Q, represents a suitable base or bed-plate, on which the reelAis supported by the standards G t, in such manner that it may revolve freely.

. The reel may be constructed in any ordinary or suitable manner, being provided with the spiders H H, and the slats N N, about which the hose B is wound. I prefer however to make the spiders of the cast segments represented in Fig. 5,each segment comprising one or two spokes and a portion of the rim, and to arrange the slats N so that they may yield inward slightly on springs or, in order to permit the expansion of the hose when the water is admitted into it. nor ends of the spokes I are clamped between the head J and the fiangerof the cam E, (see Fig. 4) suitable radial recesses being formed in the head or the flange, which are secured together by bolts. The outer end of the spokes and the ends of the curved segments are halved onto each other, as represented at d g, and secured by bolts or rivets. An enlargement, f, on the spokes I, prevents the slats from being forced too far outward by the springs s. The ends of the slats are slot ted to fit the spokes, so that the slats can move lengthwise of the spokes.

The valve D is attached to the supply-pipe O by the elbowl and nipple 70, Fig. 4, or other suitable connection. The valve is preferably of the straightway type, being arranged to be opened and closed by the lever F. The disks 0 are arranged to close against inclined seats in the valve-shell-,the position when closed being indicated by the full lines in Fig. 3, and when opened, by the dotted lines 0'. m is a flanged cap through which access is had to the disks and seats. The valve stem 1 passes through a suitable stuffing box and is attached to the lower end of the lever F. The disks are provided with projecting arms, j, Fig. 3, so that as the lever swings from F to F, the disks are shifted from c to o, and the valve opened. An arm a, pivoted to the lever F, by means of the pin 1) and extension piece K, carries at its lower end the roller L, which bears against the outer surface of the spiral cam E. The arm a rests against the lever F, so that, as the cam revolves in the direction represented by the arrow in Figs. 2 and 3,'the lever is shifted from Fto F, thereby opening the valve and admit-ting water to the hose on the reel. The axis of the valve and its operating lever, as shown in Fig. 3, is cocentric to the axis of the cam and real and The inits position is such that when the valve. is I closed the roller Lwill bear against {hntPor tion of tl "am n ar. at the cam center, but when the valve is open and the lever at the extreme of its valve opening movement, the roller will be farthest from the cam center. The end of the lever serves as a handle for opening or closing the valve, and, when the cam is revolved backward, the arm ct and roller L swing outward to the position indicated at a L. By this construction the roller is prevented from interfering with the reverse motion of the cam. It will also be understood that the first revolution of the reel and cam, opens the valve fully by swinging the lover and roller to F L, and that, after these parts have arrived at this position, the cam can revolve as the hose is unwound further, without affecting the valve.

The pipe 7t, Fig. 4, is screwed into the inner end of: the valve shell, and the head revolves on it-,being supported by the standard G and cap 0. The head is provided with a circular flange, '0, Fig. 4, which surrounds the pipe 71, and has at its outer end a flange 20, which turns in a growe in the cap and in the standard (1- The interior surfaces of the cap and standard are made hexagonal, to fit. the inner end, as, Fig. 4, of the valve D, and inside the end of the valve a circular recess is formed, which is filled with any suitable packing, 3 preferably a packing containing plumbago,which packing extends the full .ength of the pipe 71, as indicated at y, Fig. t,-the inner surface of the circular part c Jeing formed of a Babbitt-metal sleeve, it desired. The inner side of the head is provided with the bend or elbow, e, to which the hose .3 is attached by the screw-connection o.

p is a boss on the elbow c, which receives he shaft 1, which extends to the opposite .pider I1, and serves to hold the reel together. .he cap 0 is provided with flanges and bolts iy which it is secured to the standard, and he packing compressed so as to make the oint tight. By this construction, the metalto surfaces which revolve are kept out of ontactwith each other, so that they are preented from sticking t gether from rust.

The cap J is referably provided with a rojection or flange 0', Fig. 4, which engages ver the hexagonal end of the valve shell and ssists in holding the parts together. The 1p and standard prevent the valve from lrning on the nipple 76.
