STREET FIRE-HYDRANT.
Specification of Letters Patent.
Patentedduly 6, 1915..
Application filed May 1, 1912. Serial No. 694,323.
T0 all whom it may concern:
Be it known that I, CLAUDE L. Howns, a citizen of the United States, and resident of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Street Fire-Hydrants, of which the following 1s a specification.
This invention relates to street ire hydrants, and its chief object is to embodyin a hydrant a construction adapted to facilitate the emission of water from the hydrant casing so that there will be less loss of pressure incidental to passing through the hydrant casing than there is in hydrants which have hitherto been devised.
Of the accompanying drawings which illustrate the invention,-Figure l represents a vertical section through a hydrant partly broken away and shortened. Fig. 2 represents a horizontal section viewed I lpwardly from the plane indicated by line 2 2 of Fig. 1. Fig. 3 is a vertical sectlon of a modiication.
The same reference characters indicate` the same parts Wherever they occur. y
The barrel or casing of the,y hydrant is made in two sections, in accordance with the usual practice, said sections comprlslng an upper or exposed section 10, and the lower or concealed section 11, the upper section being disposed above the ground level, and the lower usection being below the ground level. The meeting ends of the two sections are secured together at 12. A pot 13 below' the section 1l is formed to provide a chamber 14 for the main valve 16 and to provide an inlet sleeve or hub 15 to receive a water main (not shown). The seat for the mainl valve is indicated at 17.
The valve stem comprises two coperative screw-threaded sections indicated respectively at 18 and 19 of which the former is tubular and is internally threaded for connection with the screw-threaded portion 20 of the section 19. The section 19 is journaled in the head 22 of the barrel and may be rotated but is prevented from moving vertically.
The hydrant barrel is provided with one or more, in the present instance a plurality of, outlet passages into Whose inner ends water flows upwardly. These passages are curved so that their outer ends emit water horizontally, the Walls of the outlet passages being curved in such manner as to tion 19.
gradually change the direction of the water, and being graduated in form to divide the main stream into smaller streams and to gradually change the cross-sectional shape of the latter without subjecting the water to any abutment which will materially reduce its velocity or progress. The outlet passages are indicated at- 2l and they are formed in the head 22 at the upper end of the barrel. Outlet valves 23 are secured by bolts 24 to the barrel. The curvature of the Walls of the outlet passages 21 is such that, when the outlet valves Vare open, the Water will issue horizontally from the hydrant casing without being churned. or otherwise seriously impeded. The inner ends .l0 of the'webs or division Walls Which separate the outlet passages 21 are made as sharp as 'possible in order to cleave the water without offering any undue resistance to the same.
As shown by Fig. 2, the sharp edges 40 which cleave the water'to form the separate streams are disposed radially with reference to the axis of the barrel. "Ihe water, upon being divided by these edges, first takes the form of sectoral streams, and while the direction of the streams is being gradually changed, theshape of the streams is 4also gradually changed to circular. The gradual changing of the surfaces of the passageways 21, whereby the shape of the streams is gradually changed, offers the least possible resistance to ghe flow of the water.
The head 22 is provided with a stuiiing box, the gland of which is indicated at 26, to prevent leakage of Water through the opening occupied by the section 19 of the valve stem. A collar 25 on the section 19 bears against the under surface of the head 22 `to resist upward pressure uponthe Valve stem. A collar 27, secured on the section 19 by a set screw 28, rests upon the gland 26. A false nut is journaled ina cover or cap 31 and has an angular socket (not shown) coacting with the angular end 29 of the sec- This nut has exterior angular faces'32 adapted to be engaged by 'a wrench for operating the main valve. l The rim of the cap or cover 31 has a flange 33 which is seated upon the upper surface 34 of the head 22, and is attached by bolts 35 Whose heads are countersunk in sockets 36 formed in the iange 33.
In the modification shown by Fig. 3, the head comprises a removable plug 22x in which the Waterways :21X are formed substantially as hereinbefore described. The plug rests upon a shoulder 37 formed on the Section l0, and is held in the latter yby the cap 3l. A gasket 89 is arranged to prevent leakage through the annular crevice be'- tween the plug 22* and section '10. The section l() has outlet ports 38 which register with the delivery ends of the Waterways 2l".
