GEORGE R. BABBITT, OF PROVIDENCE, RHODE ISLAND.

BARRELeFlLLER.

SPECIFICATION forming part of Letters Patent No. 517,136, dated March 27, 1891i. Application led September 4, 1893. Serial No. 484,747- (NO model-l .To a/ZZ whom t may concern:

Be it known that I, GEORGE R. BABBITT, a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Barrel-Fillers; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part ofthis specification.

The device forming the subject of my present invention relates to improvements in barrel fillers, so-called, provided with automatically closing valves; and it consists essentially in the vnovel construction and arrangement of the valve-actuating mechanism combined with a protected float, &c., all as will be morefullyhereinafterset forth and claimed.

Hitherto, in barrel-fillers of the class re# ferred to it hasbeen usual to employ a comparatively small oat working in a chamber formed at one side of the interior of the charging pipe. Moreover, the valves controlled by said oat were closed by the pressure of springs. There are objections to such former devices; for example, the float is not sufficiently sensitive in its action owing to its small area, thereby requiring considerable vertical movementv to trip the valve. The oat chamber is easily clogged, thus rendering the device inoperative for the time being. It cannot be used for comparatively slowflowing materials, such as heavy oils, coal tar, molasses, &c. Since the float-controlled valve is closed by means of a spring its action is uncertain, as it is well-known that springs are liable to becomeinoperative at any time.

The object I have in view is to provide a Y barrel-filler devoid of the objections before referred to. In myimproved device the passage way for the liow of the liquid is practically free and unobstructed throughout, a full area being maintained at all points; the ioat is comparatively large in area, a short vertical movement being sufcient to trip the valve; the oat and its rod or stem are completely protected from the action of the flowing liquid; the valve is so located with 'respect tothe tripping or releasing mechanism that its own weight and leverage operate to quickly close it whenever the tripping arm is freed, and finally the device as a whole mayk be readily adj usted'so as to fill the barrel or vessel to any pre-determined height.

In the accompanying sheet of drawings, Figure l represents a side elevation of my improved barrel-filler in its normal position. Fig. 2 is a vertical sectional view taken through the center, showing the apparatus as in use, the valve having just been tripped and the supply cut off through the medium of the elevated iioat. Fig. 3 is a partial end or side elevation, viewed from the right of Fig. l. Fig. 4 is a partial sectional view, showing the position of the valve, &c., while the liquid is passing through it, as in use, and Fig. 5 is a transverse sectional view, taken on line :n

l municating with the supply tank or reservoir in any well known manner. The charging or outlet nozzle c2 is arranged at substantially right angles with the nozzle c/its lower end being open and forming the float chamberf. Within the said chamber is mounted a central float f secured to a small stem or rod d extending upwardly through the casing, its upper end being attached to the float lever h fulcrumed at h to and between brackets a3 integral with the casing. The ioat is protected from the action of the flowing material or liquid by means of the fixed coneshaped partition f2 located at the top of the Iioat-chamber. The walls of the outlet nozzle or tube are provided with peripheral openings e having a combined area equal to or exceeding that of the inlet nozzle; these openings it will be seen are located just above the top of the lioat chamber.

In order to guard the Iioat-rodfrom injury, che., I provide the apparatus with a tube c which isxed to the partition f2 and passes through the top of the casing; the rod is adapted to play freely within this tube, the latter at the same time forming avent to the IOO chamber. As drawn, the upper end of the tube c forms a stop for the lioat lever to arrest the latter in its downward movement.

A drop-valve i; is mounted within the casing chamber, its seat c' being located at the base of the inlet nozzle. A cap a4 is screwed into the top of the casing and is bored out to receive the upper portion of the valve; a light spring s being interposed between the lo Valve and cap.

The valve tripping device includes the horizontal shaft b mounted in the upper-portion of the casing; said shaft being located at one side of the center of the valve and i 5 tube c. The shaft is bent to form a crank h', adapted to receive the lower or forked end of the connection m; the upper end being inserted into and supporting the valve. The shaft extends outwardly through a plug d2 zo screwed into the side of the casing and carries at its free end a tripping-arm or lever g, an end of the latter being adapted to contact with the float-lever 7L. As thus arranged, see Figs. l and 5, it will be seen that when the valve is lifted or open the leverage is such that it acts to automatically drop or close the valve upon tripping the arm g, since there are no dead centers.

In filling barrels with oil, the., it is usual to 3o leave more or less of an airspace or chamber in order to allow the fluid to expand` the volume of such space being determined by the nature of the material iilling the barrel, at the same time taking into consideration the section of country to which itis to be shipped. In order to so adapt the apparatus that it may be adjusted to the varying oonditionsjust referred to I provide the charging tube a2 with a screw-thread on which are mounted a nut 4o n and check-nut n; the nutnhaving a series of downwardly bent lugs u2 arranged to rest upon the barrel and support the filler. It is obvious that the air space is controlled by changing the relation of the float to the nuts.

From the foregoing description it will be apparent that upon introducing the [ioat-end of the previously adjusted fillerinto the barrel B, say through the bung-hole p, Fig. 2, connecting the nozzle a with the supply 5o system and finally opening the valve 0, the arm g then resting against the lever h, the liquid will flow freely past the valve and be discharged through the several openings e.

The flowing liquid does not touch the float in its passage, but as the filling operation nears completion the rising liquid enters the float chamber and gradually lifts the float, thereby at the same time elevating the lever h from the position shown in Fig. l until it rises past the end of the arm g, at which instant the 6o weight of the valve, dac., automatically rotates the shaft b and closes the valve, thus shutting off the supply to the barrel. Fig. 2 shows the corresponding relation of the several parts. The filler is next withdrawn from the barrel and another barrel substituted; the operation of filling being repeated upon again placing the filler in position and lifting the valve.

By means of my improvement the float is fully protected; it has a comparatively large 7o area, and it is very sensitive in action, owing to the fact that it cannot become clogged because there are no small ducts or passages communicating with the charging tube. The flow of the liquid into the barrel may be fast or slow, the action of the float being unaffected. The tube c forms a vent for the iioat chamber, is unobstructed throughout and pcrmits a free movement of the float rod therein.

l claim as my invention- 8o lu a barrel-liller, the combination with the discharge or outlet tube 0,2 having its lower portion provided interiorly with a partition extending entirely across the tube to form a float-chamber beneath and having the walls of the tube above said partition perforated for the free passage ot' the liquid being barreled, of an inlet nozzle arranged to communicate with a reservoir or source of supply, a fixed guide-tube c extending upwardly from 9o the float-chamber and through the casing of the filler, a self-closing inlet valve, a suspended float located in said float-chamber and practically non-movable laterally, and tripping mechanism connected with said valve and float, whereby the latter in moving upwardly releases the tripping mechanism automatically, substantially as hereinbefore described.

1n testimony whereof l have affixed mysig- 10o nature in presence of two witnesses.
