Specification formingpart of -Letters'PatentNd 174,551, dated March 7', i876 g" application filedv A l February 19, 1876. l
To allwhom it mag/concern Be it known that I, DAVID McKENZHm J r.,
ot' Washington, in the county of Washington and'in the District ofColumbia, have invented certain new and useful Improvements iniGlobe 1' or Compression Valves; and do hereby declare that the-following is a full, clear,-and. exact description thereof, reference .being had to the accompanying drawings, making apart of this specificatlon, in which- Figure l represents the parts of an ordinaryv section of an ordinary compression faucet or' spigot, provided with my improvement; and Fig. 7 is a vertical central section of an ordinary conical-seat globe-valve provided with my improvement, and with the valve open.
Letters of like name and kind refer to like parts in each ot' the figures.
The object of my invention is to provide 'means whereby globe and compression valves and spigots having flaty or conical seats, whether used for steam, water, or any other liquid, may be rendered self-packing; and it consists, principally, in a ring or washer prol vided with a V-shaped annular groove upon its upper side, and placed at the lower end -of the cylindrical chamber of' a globe or compression valve, in such a manner as thatl the said V-shaped annular groove shall furnish a seat for and confine the lower end of an elastic tube, for the purpose substantially as is hereinafter shown and described. It consists, further, in the means provided for opening and closing the waste-pipe of a globe or compression valve automatically, in the m-anner and for the purpose substantially as is hereinafter shown and described.
In the annexed drawings, A represents a cyliudricalchamb'er, the 'side walls of which areformed bythe Aupper part'otl the globe.y 'casting A. rlhe lower end of said chamber' A is rformedby a washer or ring, B, that is provided with la V-shaped groove upon its upper side. The upper end is formed by a cap, B', that is fastened to and secured upon the globe-casting by means oiscrew-threads, in the usual manner. The lower-end of the inner, portion ot' said cap B' is made conical,asl showny in the drawings, for the purposes. that will beimore -fullyexplained hereinafter. vA hole is-boredv through lthe cap B', longitudinally, and centrall with the valve-seat C, and said hole is kprovided with an internal screw, to and `within which Athe valve stem D isfitted, by means o f which arrangement the valve E is enabled to be opened and closed. The valve E is secured to and upon the lower end of the valvestem D, either rigidly or loosely, as desired, in the usual manner, and, as thus secured, furnishes a bearing or support for the washer or ring B, the latter resting upon the former. The stem D is fitted to pass through the washer or ring B loosely, so that when said stem is screwed outward or inward, the washer will not necessarily revolve with the stem. An elastic cylindrical tube, F, composed oi' india-rubber or any other suitable substance or material, is caused to encircle the stem D within the cylindrical chamber A,
and isv made of sufficient length to ll said Y.
chamber longitudinally, but is somewhat smaller in diameter than said chamber. The lower end of the elastic tube F rests upon the washerB within the annular V-shaped groove, and the upper end of said elastic tube projects into and fills the conical portion ot' the cap B.
By reference to the drawings, it will be seen that when the valve E is upon its seat there will be an annular space between the outside of' the cylindrical elastic tube and the inside of the cylindrical chamber A.
As thus constructed, the chamber A and the attachments directly pertaining to the same are complete, and its operation is as follows: When the valveE is closed, as shown in Figs. 2, 4, and 6, the cylindrical elastic tube F fills the space between the valve'E and the lower end or conical portion of the cap B', leaving an annular space between the said elastic tube and the side walls of the cylindrical chamber A, At the instant the valve E is raised oft' its seat, the elastic tube F begins to. compress longitudinally, increasing at the same time in diameter suficiently to fill the chamber A, as shown in Figs. 5 and 7 and, by means of the conical p0rtion of the cap B" forming the upper end of the chamber A, the elastic tube F (as the valve E continues to rise) is compressed so tightly around the valve-stem D as to effectually prevent steam, water, or other liquid from escaping outward through the hole provided in the cap B for the valve-stem D.
Figs. 4 and 5 show the application of this improvement to hydrants for re and do mestic purposes1 shower-cocks, water-cranes for railroads, &c. Y
By reference to the drawings, Fig. 4, it will be seen that when the valve is closed upon its seat the annular space between the elastic tube F and cylindrical chamber EA affords ample space for water or other liquids that remain above the valve E to pass out through the waste-pipe G. -y I Fig.5 shows the valve open, and by the compression of the elastic tube F, which is increased in diameter bv the opening of the vvalve, the wastepipe G isclosed.
This improvement is equally applicable to all descriptions of globe and compression valves, shower-cocks, hydrants, watercranes &e., whether used for steam or water, and
from the fact that it enables waste-valves to be dispensed with, and furnishes a complete and reliable selfacting packing for the stem of the valve, it is believed to possess advantage superior to any in use.
Having thus merits of my invention, what I claim as new 1. In combination with the valve-stem D and elastic tube F, the washer B,provided with the V-shaped annular groove upon its upper side, the'ottice of which is to provide a seat for the elastic tube F, and confine the lower end ot' the same in position, so that said elastic tube cannot spread or become enlarged at its lower end, in the manner substantially'as shown and described. l
2. The combination of the -valve-stemD, elastic tube F, and waste-pipe G, by means of which combination the latteris enabled to be opened and closed automatically, in the man-f ner and for the purpose substantially as shown and described. l e v In testimony that I claim-the foregoing I have hereunto set my hand -this 19th day of February, 1876.
