PETER N. BARDO AND THOMAS FORD, OF NEWPORT, KENTUCKY.

SPECIFICATION forming part of Letters Patent N o. 352,288, dated November/9, 1886.

Application filed July 24, 1886.

To all whom t may concern:

Be it known that we, PETER N. BARDO and THoMAs FORD, citizens of the United States, residing at' Newport, in thecounty of Campbell and State of Kentucky, have invented certain new and useful Improvements in Hydrants, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification.

Our 'invention relates to that class of hydrants generally known as fire-plugs"7 or street-washers, and has for its object the improvement in construction and efficiency of operation of this class of hydrants.

The novelty of our invention will be herein set`forth, and distinctly pointed out in the claims.

In the accompanying drawings, Fig-ure l is a longitudinal central section in elevation of a hydrant containing our invention and with the valve opened. Fig. 2 is a corresponding View with the valve closed. Fig. 3 is a plan view of the cap. Fig-4 is a sectional plan through the line x x o f Fig. l. Fig. 5 is a plan view of the cut-off ring for the waste. Fig. 6 is a side elevation ofthe same. Fig. 7 is a bottom plan view ofthe valve-rod guide. Fig. 8 is a plan vicw of the adjusting-ring.

The same letters of reference indicate identical parts in all the figures.

The stock of the hydrant may be said to be composed of the cap A, body B, waste-chainber C, and valve-chamber D. These parts are connected together as follows: The upper end of the valve-chamber'D is provided with a liange, c, onto which is bolted a ring, E, whose inner surface is threaded. The bolts or screws b,which secure this ring tothe flange a, pass through segmental slots c, Fig. 8, in the ring. The waste-chamber C is flanged at its upper end,an'd is bolted by screws d to a correspond- `the stock. As `many vents or nozzles G are Serial No. 208,908, (No model.)

provided as desired, and these may be covered by ordinary screw-caps, H, ,in the usual or any seen in Figs. l and 2, is formed with an annu-y lar recess, which receives any suitable packing and ts over a boss upon the iiange ce. Its interior portion, 7L, enters the valve-chamber, and is beveled, as shown, to form the valveseat.

I is 'the usual inletcoupling opening into the valvechamber.

7 The above constitutes the stock or shell of our improved hydrant, the advantages of which, without reference to the valve-rod and valve mechanism, may be stated as follows:

By connecting the body B and waste-chamber C with flange-j oints, instead of having them integral, as is the general custom, not only is a guide provided for lthe frost-jacket, but in case of raising the grades of streets it enables a new member to be bolted in between the bodyB and waste-chamber C, to give sufficient lengthto the stock and meet the requirements of the new grade; and this can be done with very little trouble, and it prevents the necessity of replacing the entire hydrant with a new one. Of course, in such4 case the valve-rod would have to be lengthened, but this could be easily done by either screwing or welding in a new piece. Again, by means of the slotted ring E and the screw-joint between the valvechamber and waste-chamber, the stock can be adjusted nicely on, its axis to bring the nozzles in proper position over the-gutters, for it is desirable to have the screw-joint as tight as possible, and in screwing it all the way down the nozzles mightnot be in proper position. It would not be desirable to lunscrew. the joint any to get the adjustment; but by loosening the nuts that hold the ring E it could be turned with the stock to effect the desired adjustment and be again bolted down tight.

The valve-rod .I is entirely solid, and is not drilled or perforated at any point. The valve K, of usual construction, is secured to its lower Ico end by a nut, fi. AboveV the valve K, within the waste-chamber, is a ring, L, which snugly fits the bore of` said chamber, and is secured to the valve-rod by a set-screw, j, passed through its hub. This ring has a'chamber on one side, in which is placed any suitable packing, k, arranged to cover a waste-aperture, Z, and the adjustment of' the ring is such that when the valve K is opened the aperture Zwill be closed by the packing 7g of the ring, and when the valve is closed the waste-aperture Z, as seen in Fig. 2, will be opened to permit the escape of water from the stock, and thereby prevent the freezing of the hydrant in winter. To properly guide the valve-rod, and to prevent it from turning, We provide the guide-piece M, Figs. 1, 2, 4, and 7, which has at its upper side a ilange, t, that rests in a recess in the flange f, and is prevented from turning by a detent, m, entering a notch in the flange of the guide, as shown in Fig. 4. The flange of the guide M is clamped between the flanges e and f. The guide has a pendent shank, n, with a square socket, o, into which the valve-rod, also made square in cross'section at this point, fits. The

upper part ofthe guide is chambered out to contain packing and receive astufng-box, p. The valve-rod, after passing through the stuffingbox into the cap A, is threaded at its upper end and screws into a revoluble nut, N, which passes through the head of the cap, and is held from displacement by a collar, o, and nut s, as shown. By turning the vnut N the valve-rod is raised or lowered to close or open the valve. By thus making the valve-rod solid, without perforations, it can be made comparatively light and still have all the strength requisite or necessary.

Having thus fully described our invention, i

we claim- 1. The combination, with the valve-chamber D, having the flange a, of, the ring E, bolted through segmental slots to said flange and threaded on its inner periphery, and the wastechamber threaded at its lower end to engage with said ring, substantially as and for the purpose specified.
