FREDK..H. BARTHOLOMEVILOF NEWYORK, ,N. Y.

HYDRANT.

Specification of.-Lette1s Patent No. 4.41.0, .dated Marchi?, 1846.

To all/whom it may concern.'

Be it knownthat I, FREDERICK I-I. BAR- THoLoMEw, of the city, county, and State of New. York, have invented'a new and useful improvement in the construction of stop.

cocks or valves anditheir applicationoi and combination with hydrants for the purposeof' introducing water ory other'fluids from 1 aqueducts or otherwise; and I do hereby de clare Vthat. the ollowingis a full,.clear, and exact description of the construction and application of the same, reference being had to the annexed'specication and drawings7 making a part of this specification..

The nature of my invention consists in an improvement in the construction of pistonsfor valves or stop cocks which by the action of the water and atmosphere shall close so gradually and gently as not to destroy lead pipe by concussion and by which also when applied in combination with a plunger for hydrants shall form a chamber into which a portion of water in the hydrant may recede below the action of frost and not waste into and saturate the earth.

Figure 1, is a sectional view by which A A represents the stock of a hydrant which may be of wood or metal say 5 or 6 feet long having a hole straight through it of say 4 inches diameter.

B is a plunger of wood or other material of proportionate length to the stock and about one eighth of an inch sinaller than the bore through the stock, the t-op end beveled and inclined toward the spout G having a handle C, of sufficient strength extending up through the cap F and on which is fitted and secured an iron handle or knob E. D D, a hollow plug inserted into the top of the stock about 5 in. long for the purpose of preventing the waste from dashingl against and wetting the part of the handle exposed to the weather when the hydrant is closed and so prevent the handle from being frozen fast. This object may also be eiected by constructing the cap F with a hollow hubl cast with the cap (if made of metal) extending from the lower side downward about four or five inches-and also the same object may be effected by attaching a dasher or collar onto the handle between the cap F and the top of plunger or piston B.

F is a cap of iron or wood secured by screws or otherwise and having a square hole or other shaped hole in the center with on the bottom. This will require more 'the handle E working. through it yand; so

fittedto itasnotto admit of being twisted `around by a ,groove-and'tooth or bybeing square. v`

H, II, is a wood; plug driven up tight v'intothe bottomzo-f the stock :about five inches long, .hav-ing a' hole inits. :center of suitable size -to admitthe valvefore stop cockI I.v

I, I, is a metallic tube or cylinderofaabout Ysix inches length androne and a half; inches diameter: inside, being-A closed at the top except an aperture of about three fourthsof an inch. The-bottom being closed by. a screw cap M.

N is an arm or elbow to which is attached by a coupling or otherwise the pipe or tube conducting the water, land of same capacity as the pipe or conductor.

K, K is a metallic turned piston or plunger about nine inches long including the shank R, having a shoulder or flange fitting the bottom end of plunger B. A part of this flange Y is square for the purpose of its being screwed into the plunger B. Below the shoulder or flange and extending about 1% inches is a stem about in size, thence extending downward about one' inch the size is increased to about a2 inch, extending downward of same size about 3 inches the size of this last 3 inches being adapted to and just filling the aperture 'I in the top of the tube or box I, I, so as to work through the aperture easily. Below this part of the piston is a stem or screw about in. thick and one in. long, onto which is put the leather or india rubber washer V which is fastened and secured by nut W.

Fig. 2, is a sectional view of another mode of constructing a value or stop cock. A A the barrel or tube. B the piston. E nut securing the washers D, Gr. C, cap screw to open it than that in Fig. l. A

The hydrant as shown in Fig. l, is in an open position (to discharge) the water being received in through elbow or joint N, passing up through box I, I, through aper# ture T, thence up through the space between the plunger B and the hole in the stock A A out of spout G.

The hydrant is made lto discharge by pressing down upon the handle E, which forcel with the plunger B and the piston or plunger K K must be depressed about four inches to produce a full discharge and which upon removing the pressure will rise upward and close by means of the oating of the plunger B (if light enough) and thepressure of the water against the bottom of the piston K, K, and when the plunger B and piston K, K, have risen up until at the point X Fig. 4, the piston then cutting ofi' the communication of water by closing or iilling up the aperture T, and still rising move together with the plunger above (the communication being closed) form at the bottom of the plunger and above the Cylinder I I, a chamber or space into which the water contained in the space between the stock and plunger B, falls below the action of the frost while at the same timeit is retained within the stock of the hydrant and not permitted to Waste into and saturate the ground at its base.

What I claim as my invention and improvement and desire to secure by Letters Patent is y 1. The combination of the plunger B with the piston or valveJ cock K K in the manner and for the purpose described.

2. Also I claim the combination of the plunger and piston with the hydrant substantially as described said combination effecting the double purpose of checking the concussion from the water and of furnishing a variable chamber in which the waste water may descend away from the iniiuence of frost, and not waste away into the` ground.

3. I also claim the construction ofthe pis ton K K by which the aperture `T is `closed before the -i'ull closing of the valve and which when combined with the plunger shall furnish a variable chamber for the `purpose herein set forth.
