HYDRANT.

SEEGIFIAION forming part of Letters Patent No. 484,197, dated October 11 1892.

Application filed March 14, 1892.

T all,whom z't may concern- Be it known that I, JOHN A. GREGG, a citizen of the United States, residing at West Bay City, in the county of Bay and State of Michigan, have invented certain new and useful Improvements in Hydrants, of which the following is a specification, reference being had therein to the accompanying drawings.

' This invention relates to improvements in hydrants; and it consiste in the combination, with the vertical hydrant-column, of an outer casing or jacket for inclosing the lower portion of the colnmn, and with the upper end of the jacket fitted to thecolumn and with its sides diverging in a conical form for inclosing an annular chamber between the column andthe jacket, and With the lower end of the chamber open to receve the gases from the earth below; and the invention also consists in the construction, arrangement, and combination of the parts, together with the operation of the saine, as I shall hereinafter explain in detail, and which will also be especially set forth in the claims.

The objects of the invention are to provide means for preserving the lower portion of a hydrant-column and the valve contained therein from the action of cold and frost, whereby the valve is rendered at all tirnes free and easily operated, and the connections and joints are preserved against leakage and breakage.

Another object is to provide a jacket for the lower portion of a hydrant to protect the column and the valve from the action of frost and at the same time to allow the earth inclosing the lower portion of the jacket to heave and expand by the action of frost without lifting the column.

' Another object is to provide a jacket for Serial No. 424,828. (No modal.)

Figure 1 represents my invention in vertical section as attached to a hydrant-column. Fig. 2 is aviewof the same in elevation. Fig. 3 is a horizontal section et Fig. 1, taken atac. Fig. 4 is a transverse section of the lower end ofthe hydrant-colnmn, shown detached. Fig. 5 is a plan view of one of the cap-sections detached.

1 represents a hydrant-column of any desired form and construction, and 2 is a branch from the water-main connected to the lower end of the column by radial lugs 3 on the base of the column and a radial flange 4 on the upwardly-turned portion 5 of the pipe 2,the lugs 3 being each provided With a slot l3, while,the fiange 4 is provided with bolts 6, tapped into the fiange, so that when the lugs 3 are placed upon the flange 4 the column can be turned to pass the slots 13 over the bolts below their head portions, and the bolts are then tightened to draw the parts together in the nsnal manner, and this allows the bolts to be loosened and the column to be turned until the bolts are free from the slots, and the colnmn may then be removed for repairs or replacement, as Will be more fully explained presently.

7 are a series of lugs extending from the outer edge of the flange 4, with a suitable space between, and on the outer portion of these lugs rests the base of a jacket 8, which has a conicalform and surrounds the lower portion of the hydrant-column, its upper end being of a dimension to provide an annular space 14 between the jacket and the column j ust above the surface of the earth, in which the lower part of the colnmn is embedded, while the base of the jacket is of such a dimension as to provide an annular space or chamber 9 between the column and the jacket, and also to leave openings 10 from the earth below to the chamber 9 between the lugs.

20 is a cap or cover for closing the upper end opening of the chamber 9, and this cover 20 is composed 01: two halves or sections 15, as shown in Fig. 5, each having an inner recess 16 for inclosing one-half of the colmn, and is provided on its periphery with a downwardly-extending fiange 17, fitted to pass tightly over the upper end of the jacket, and is also provided on its end portions With radiallyprojecting ear-pieces 18, which When the two sections are in position to cover the upper end of the jacket the parts are firmly clamped together by bolts 1 9, passed throngh the ear-pieccs.

The lower edge of the jacket is provided with a radially-extendingflangell, which rests upon the lngs 7, and bolts 12 are passed through the fiange and the lugs for holding the jacket 1n place. When the jacket is chus firmly fixed in place and secured to the lugs 7, the cap-sections are then placed in position and secured, and. the earth is then filled in around the jacket nearly to its upper end portion, and should it beoome necessary to repair the hydrant the cap-sections are loosened and removed, and then a wrench fitted to the heads of thebolts 6 is passed downward through the opening 14 and the chamber 9 and engaged with the bolt-heads, Which being loosened allows the hydrant-colnmn to be turned t0 d1sengage the bolts from the slot 13, and the column maythen be lifted out and again replaced and the parts adjusted withont digg1ng or otherwise disturbing the earth which 1ncloses the jacket. The branch pipe 2 and the lower portion of the hydrant-colnmn be 1ng placed in the earth below the action of frost and the lower portion of the jacket be- 1ng also below the action of frost and within the influence of the warmth derived from the ear th below the frost-line, the chamber 9, Wh1ch is open below and with a free communication with the heat radiating from the warmer strata of earth below, brings the air contained in the chamber 9, by means of the usnal circulation on account of the greater,

area below and the limited area of air-space at the top to a temperature above the freezlng-point, and as this temperature surrounds the lower portion of the hydrant-column which contains the valve the colnmn is keptfree from frost and is always ready for being quickly opened When required for fire or other purposes, and the jacket being arranged for inclosing a chamber of greater area at the bottom than at the top brings the outside of the jacket to the form of a conc, or so it has an upward taper, and this form When the surface of the earth freezes around the upper portion of the jacket allows the earth to move upwardly by expansion Withont adhering to the periphery of the jacket, so that the hydrant-column romains solidly in position, notwithstanding the 11 ph eaval of the earth arou nd and in proximity thereto, and thus the hability ot straining the joints of the colnmn and branch pipe is obviated, so that leakage and the expense of repairs is prevented. It Will also be noticed that by having the jacket separated from and outside of the hydrant and arranged in the form of a cone, so that the bottom of the jacket is located at a considerable distance from the base of the hydrant-column, all water dripping or leaking from the hose connections is condncted away from contact with the hydrant-column, so that When the earth saturated therebyfreezes the jacket the chamber between the jacket and the column prevents the freezing froxn efiecting the column and provides a means of preserving the hydrant in a condition ready for use at all times.

IIaving described n1y invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combinaton, with a vertical hydrant-column provided on its lower -portion with radially-extending lugs, of a jacket of oonical form around the lowerportion of the column, and with its base resting npon and bolted to said luge, and with its upper end provided with a cover fitted aronnd the column above the earth-line, and wtha conical annnlar chamber between the column and the jacket and having openings between the lugs to the base of the chamber, for the purpose set forth, substantially as described.

2. In a hydrant, the combination of the branch pipe 2, having an upwardly-turned portion 5, provided with radially-extending flange 4, and with lugs 7, projecting from the flange, and with the bolts 6, tapped into and projecting above the fiange, with the hydrant-column 1, with its lowerend restingon said flange 4 and provided with lngs 3, having slots 13, passed over the bolts 6 beneath their head portions, and a jacket 8 around the column and with its lower open end secured to said lugs 7 and havingits upper end covered by a removable cap-piece fitted t0 encircle the body of the column, substantially as set l'orth.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN A. GREGG.
