HYDRAULIC AIR-COMPRESSOR.

SPECIFICATION forming part of Letters Patent No. 415,931, dated November 26, 1889.

Application filed February 21, 1889. Serial No. 300,699. (No model.)

To all whom t may concern.-

Be it known that We, JOSEPH WEYAND, of Guttenburg, in the county of Hudson and State of New Jersey, and WILLIAM LANG, of

the city, county, and State of New York, have invented a new and Improved Hydraulic Air Compressor, of which the following is a Jfull, clear, and exact description.

Ourinvention relates to hydraulic air-com` Io pressors constructed to work automatically, and especially to that class of compressors employed to supply and maintain a predetermined amount of air-pressure upon liquids contained in casks or tanks stored, for in- I 5 stance, in the cellar of a building, to force such liquid through suitable discharge-pipes to the ,tioor above, in order that the liquid thus raised may be conveniently drawn when and as desired through a faucet located upon the said ioors.

The object of the invention is to provide an apparatus which shall possess superior advantages in point of simplicity, durability, and general etficiencyover any similar appa- 2 5 ratus or device now employed for the same purpose.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter more fully set 3o forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters and figures of reference indicate corresponding parts in all the 3 5 views.

Figure 1 is a central vertical section through the apparatus, illustrating the parts as in position to exert pressure. Fig. 2 is asimilar section looking in an opposite direction, illus- 4o trating the parts as in position to relie-ve the pressure. Fig. 3 is a horizontal section on line x of Fig. 1 looking downward, and Fig. 4l is a similar section on line I/ Ii] ot` Fig. 2 looking upward.

In carrying out the invention the base A,

which is cast or otherwise formed of any suitable metal, is preferably shaped to have a circular section 10, provided with a central circular cavity 11, and an essentially rectan- 5o guiar section 12, having elbow-

tubes

13 and 14, integral with the under side, closed atthe inner end. The tubel 13, which is a waterinlet tube, extends horizont-ally parallel with one side edge of the base-section 12, and preferably transversely to an abutment with the longitudinal member of the oppositeparallel tube 14, which latter tube constitutes the water-outlet, and the transverse member of the outlet-tube 14: is preferably locatedbetween the base depression 11 and the corre- 6o sponding member ot the inlet-tube-ordinarily near the latter.

Upon the upper face of the base-section 12 a iiexible washer l5 is secured by a plate 16, bearing thereon, which plate is screwed or otherwise detachably secured to the base, as best illustrated in Fig. 3.

In the washer 15 and the base A a preferably round opening 18 is produced, leading directly into the transverse member 'of the 7o inlet-tube 13, which opening is adapted toreceive a vertically-bored boss 19 upon the under face ot' the plate 16, the bore extending through the plate and the boss being of sufi icient length to project about half-way into the said tube 13, as best shown in Figs. 1 and 2. The wall of the lower end of the bore in the boss 19, which constitutes a valve-opening 20, is concaved, as best shown in at a in Fig. 1, to form a seat for a ball-valve 21. A 8o preferably larger and similar opening 22 is made in the plate, washer, and base, leading into the transverse member of the outlet-tube 14, which opening is capable of being closed at the top by a disk-valve 23. The ball-valve 8 5 21 is provided with a stem 24, loosely carried up through the valve-opening 20, and pivotally secured in any approved manner to a lever 25, fulcrumed at one end upon a post projected upward from the rear end of the 9c plate 16, and the disk-valve 23 is also provided with a stem, which stein is rigidly attached to the said lever. The valve-liever 25 extends longitudinally over the plate 16 between guide-lugs 255L at the inner end of the plate and downward in a curved line within the base-cavity 11, terminating over the center of the latter.

Upon the base A a perpendicular casing or shell B is bolted or Otherwise secured, the Ioo said shell consisting of' an essentially-conical section 26 and a rectangular section 27, the side and end walls whereof are preferably inclined upward. The rectangular section eX- tends over the conical section at the top to a point at or near the center, as shown in Figs.

Y section, as shown in Figs. 1 and 2, in which it will be observed that the greater portion of the rod between the ends is of larger diameter than the said ends, whereby an upper and a

lower shoulder

31 and 32 are formed.

Two

hemispherical iioats

33 and 34 are held to slide upon the rod E30., The lower lioat is limited in its'upward movement by the lower shoulder 32, which it cannot pass. The upper float, however, is free to rise upward until it contacts with the inner upper surface of the conical surface of the shell, as shown in Fig.l 2. The contour of the shell at this point is such as to neatly receive the upper float.

A nipple 35, having an eXteriorly-threaded fianged base, is formed integral with the up- .per surface of' the cover-plate at or near the outer end, which nipple is covered by a flexible jacket 36, provided with a slit at the top over the bore of' the nipple, as best shown in Fig. 1. The jacket 36 is surrounded by a cap 37, having' an integral outlet-tube 38, which cap is held in position by a lock-nut 39, swiveled upon the nipple and screwed upon the fiange of the same. A channel 40 intersects thebore of the nipple, which channel extends longitudinally rearward and downward through the bottom of the cover-plate 2S. A second channel 4l is produced in the front end of the cover-plate, affording direct communication with the interior of the shell B and the atmosphere surrounding the same.

The inner mouths of the

channels

40 and 41 are controlled by disk-

valves

42 and 43, secured to an arm 44, fulcrumed near the outer end beneath the cover-plate, the inner end of said arm being` slotted to receive the upper end of' the .float-rod capable of being acted upon by the shoulder 31 of said rod. The

valves

42 and 43 are located one at each side of the fulcrum-point of the arm 44, whereby when one channel-40, for instanceisclosed the other channel 41 will be open.

the water entering through the inlet-tube 13 passes up through the valve-opening 20 into the interior of the shell, whereupon the two

floats

33 and 34 are elevated, thereby creating an air-pressure within the shell, which, bearing downward upon the disk-valve 23, suffices to retain the same in a closed position. The lower tioat 34 rises only until it strikes the shoulder 32 of the rod 30, but the upper float 33 continues to rise with the incoming water, and the air forced out from the shell by the entrance of the water finds an escape through thechannel 40, which is open, as shown in Fig. 1; from thence through the nipple and out through the slit iu the jacket into the cap 37, and from the cap the compressed air finds an exit through the outlet-tube 38,

lwhich tube is in communication with a barrel or cask containing the beer or other iiuid. lVhen the upper iioat 34 is carried bythe water to the position illustrated in Fig. 2- namely in contact with the upper inner surface of the conical section of the shell-the inner end of the arm 44, carrying the

valves

42 and 33, is elevated sufficiently to close the mouth of the channel 40 and open the inner mouth of the outer channel 41. Through this channel the compressed air not needed in the manipulation of the fluid escapes, and as the air escapes pressure is removed from the disk-valve 23, and the lower iioat, bearing upward against the shoulder 32, raises the rod 30, thereby causing the ball-valve` 21 to close the inlet-opening 20, which movement also raises the disk-valve 23, whereupon the water finds a speedy and free exit through the outlet-tube 14. As the level of the water nears the base of the shell the upper float finds a seat upon the lower float, and as the water leaves the said upper float the weight of the latter causes the lower iioat to bear down a slight distance in the direction of the Valvelever, the length o of the lower reduction of the iioat-rod being so calculated that when the lower fioat is in this position the upper surface will be removed some distance from the lower rod-shoulder 32. In the further op` eration, when the level of the water practically reaches the level of the base, the combined weight of the floats is such that they will drop heavily downward and force the free end of the lever instantly deep in the cavity 11, whereby the outlet-valve is closed and the inlet-valve opened. The movement of the lever is so precipitated by the action of the incoming water as soon as the ball-valve is unseated in the slightest degree that the sudden violent downward movement of the iioats and lever creates quite a loud report.

The cavity 11 is always more or less filled with water, consequently the floats rebound somewhat after striking the same, but the distance between the lower float and the shoulder is such that even at the greatest rebound the two will notcontact; thus the lever remains passive. Any well-known or approved forrn of regulator may be employed in TOO IIO

connection with the compressor above described.

Having thus described our invention, we claim as new and desire to secure by Letters Patentl. The combination, with a shell having water inlet and outlet openings, a lever pivoted within the shell, two valves controlling said openings and connected with said lever, and a vertical rod connected at its lower end with the said lever and provided with vertically-sliding` floats, the lower float having a limited upward movement on the rod to raise it, of air delivery and waste channels in the upper end of the shell, alever provided with valves for both channels and extendinginto the path of the upper float, substantially as set forth.
