Description

l .@niteh tatesatent @ffice ZEBULON E. OOFFiN, OF BOSTON, MASSAOHUSTTS, ASSIGNOR TO BOSTON MACHINE COMPANY.
IMPROVEMENT IN HYDRANTS.
tite Stimuli tefttnlr tu in that Enters @that anointing ntttqqntttganr.
Be it known that I, ZEBULON'EOOFFIN, of Boston, in the county of Suolk, and State of mliIassaehusetts, have invented a new and useful Improvement in Fire-Plugs or Hydrants; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to th'e'annexed drawings, making a part of this specification, in which- Figure 1 is a sectional elevation.
Figure 2 is a sectional view on line Y Z.
Figure 3 is a sectional view online W X.
Figure 4 is a'pla'n of the cover. l
Figure 5 is a sectional elevation of the upper 'part of a flush-top hydrant, which maybe used instead of the post-hydrant. y
The part C is the base or bottom; o being Va tie or strengthening-piece in the water-way, and one of several guides for the valve H. i v v Upon the top of the part C, and above the joint, between the base and the stand-pipe or body of the hydrant,
, is an enlargement or bowl, C', Awhich has upon its upper edge an annular projection for the hook-bolts L L to take hold of to secure the body of the hydrant to its base. This bowl receives the waste water discharged through the pipes M M, and discharges it through the holes n n n. This bowl should be made just large enough .to receive thelower end of the stand-pipe, andl leave suilcient room forthe necks of the hook-bolts, which are flattened opposite the projection, that they may not occupy more room than is necessary to proper strength, so that when all the parts are in their proper place, the hook-bolts are prevented from 4getting out of place, the lower end ofthe stand-pipe occupying the space between the hoch-bolts.
n n 'tt are holes, for.tl1e waste water to pass through. a is an annular projection on the top of the hase, for tho hook-bolts LL to take hold of to secure the body to the base. This 4projection is madeall the way round the base, that the hydrant-pipe may bc conveniently placed at any equired angle to the main, as it' cannot be when Ithe common lugs or bolts in usc are used.
, I-I isthe valve for closing the water-way. M M are waste-pipes, to free the hydrant from'water when not in use. I I, the valves, to close the waste-pipes, when the 'hydrant is in use. K is the valve-stem.V A is the body or'stand-pipe ofthe hydrant. B is the hydrant-case. D is the frost-jacket. I is the hose-nozzle. U, the cap to hosenozzle. S, gland to smiling-box. y G, the nut by which the valve is worked through the rod or stem K. The lower end of this nut, which has its bearing upon the body ofthe hydrant, is so enlarged as to make a cap or cover for the stalling-'box and gland S, and by removing the` small screw at the top,.the screw upon the rod K may be oiled without removing the cover F; also, by removing the cover F the nut G may be conveniently removed, und the stuihng-box around the rod K b'c-repaeked. It also has a pocket or enlargement above the femalethread, and between it and the top, which serves as an cil-cup to the screw on the top ofthe rod K. 1*', the cover, which is held in its place by inclined lugs or bolts, and answers two purposes, viz, to hold the nut G in its place, and cover the top ofthe hydrant. E, a ring, that forms a part ofthe case.
' Advantages Gained by this Inventoni I .l
First. The valve closes the water-way at a point on a level with the top ofthe pipe, so that the water may be drawn, when the hydrant is not in use, much lower than when I the'com'mon hydrant-bend is used, thereby i rendering the hydrant less liable to injury byv frost.
Second. The hydrant'being firmly set in the ground, and the earth filled in to the ground-level, the ring E may be raised, and the nuts on the hook-bolts L L loosened, and the hydrant removed, the ease remaining in the ground, and another put in its place, or repairs made, and replaced without diggingup' the ground, thereby saving the expense of wood or brickbcxes, such as are usually used.
Third. The frost-jacket D, having a space between it and the case, prevents the earth from freezing to thecase, and the case being lifted by the frost, and is also a protection to the hydrant from freezing.
Fourth. The waste-pipesfoy this ar1engen1'ent, can be made with direct, clean openings, and the valves being opened by it' positive movement, end .notvhy springs or gravitation, are sure to free the hydrant of witter at the right time, and are not likely to choke up as in other devices in use for this purpose. I
Claims. 1. I claim the combination of the baseer bottom ofthe hydrant with the body of the hydrant, hook-bolts, Waste-pipe or pipes, and Weste-valves,hydrant-valves, and outside ce'sefall constructed in the manner end for the purpose set forth. v
2. I claim the hook-bolts L L, in combination with the body'A and bowl'C, having an annulzil projetion, a, when the parte are constructed substantially in the manner and for the purpose set forth. v 8. I claim the n'n-t Gr, in connection with the rod or valve-Stem K and bodylA, when the parts tre colistructed and arralnged to operate substantially as described.
