OIL-VALVE.

SPECIFICATION forming part of Letters Patent No. 519,306, dated May 1, 1894.

Application filed December 9,1893 $erial No. 493.228- (No modeli) I To all whom it may concern- Be it known thatI, GEORGE H. PERKINS, a citizen of theUnited States, residing in the city and county of Philadelphiaand State of Pennsylvania, have invented certain new and useful Improvements in Oil-Valves, of which the following is a specification.

In filling cans with petroleum it' is desirable that the inflowing stream of 'oil should be of large size so that the filling may be ex peditiously accomplished, and it is customary to provide the can with an inlet opening of diameter greater than that of the stream so as to afiord an outlet for the air displaced by the oil. In practice, however, it is found that the foaming occasioned within the can by the volume and impetus of a large enterlug stream results in the splashing or overflow of a portion of the liquid through the said air outlet when the level of the oil a proaches the topof the can, and renders it difficult to fill the can exactly full. It has been attempted to remedy the difficulty by charging a stream ofa given size into a can until the latter is nearlyfull, and by then, by means gt a valve, partially closing the pipe or conduit through which the stream flows, so that thereafter, the siz of the stream of oil flowing into the can being diminished, the amount of foaming within the can will be correspondingly decreased. Such smaller stream of oil, however, in descending through and issuing from the relatively large vertical pipe through which it flows, does not follow a directly vertical course, but flows over different portions of the inner face of the pipe, and, crawling outwardly across its lower edge, tends to discharge eccentrically and irregularly in different directions, with the result, the pipe notentering the can but terminating a short distance above it, that a quantity of the oil lodges upon the exterior'of the can.

It is the object of my invention to provide an apparatus by which a large volume of oil may be rapidly charged to a can or kindred receptacle until the latter is nearly full, and

by which a small stream of oil may there upon be steadily and accurately and in such manner as not to occasion foaming, charged to the can until the latter is precisely full.

In the accompanying drawings Ishow and herein I describe a good form of a convenient embodiment of my invention, the particular subject-matter claimed as novelbeing hereinafter definitely specified. I

In the accompanying drawings, Figure 1 is a viewin side elevation, and Fig. 2 a central, vertical, partly sectional, elevation, of an oil reservoir equipped with a good form of my invention. Figs. 3 and 4 are vertical, partly sectional, elevational views of my improved oil valve as mounted within the reservoir,

rior of which tapers from the vertical wall of I the reservoir, to a diameter, at its mouth a,

corresponding to that of a conduit B, the upper extremity of which is permanently fitted within said mouth. The lower portion or throat of the tapering interior of the funnel bottom a I term the reducer seat o The conduit B is of any appropriate length, and beneath it the cans to be filled are successively placed with their receiving apertures in alignment with its bore.

0 is what I term an annular reducer, the same being externally conical, so that it accurately corresponds to the conical form of the interior of the reducer seat a in which it is adapted to rest. The bore of the reducer is, as shown, as to its lower portion, straightwalled or cylindric, and within its mouth, which is conveniently slightly enlarged for the purpose, is entered and secured a pipe D. of inferior diameter to the conduit B and disposed concentrically with respect to it. The upper portion of the bore of the reducer is conical to form a valve seat at. p

In the embodiment of my invention illus- I trated, the reducer is shown as provided with p I a skeletonframe, composite, in the form shown, of armslt which extend radially away? from the reducer and have an inclination corresponding to that of the upper portion of the funnel bottom upon which they are adapted to rest when the reducer is inits scat, of a lower annular rim mounted upon the upper extremities of said arms 70, and of a diameter somewhat less than that of the interior of the reservoir,of vertical posts k the lower extremities of which are attached to the lower rim k',of an upper annular rim 70 mounted upon and secured to the upper extremities of the posts lei-and of a spider d mounted upon and secured to the rim 70 tosupport in axial alignment over the mouth of the funnel bottom, an annular head plate (i E is a valve head of such form as to accurately fit within the seat d and having by preference an extension e adapted to project into and fit within the straight portion of the bore of the reducer.

F is a valve stem extending upward from the valve head and passing through the bore of the head plate (i F is a boss formed upon the valve stem a short distance above the valve head.

The operation of the device is as follows: The reducer being in the position illustrated in Fig. 2, and it being assumed that the reservoir is full of oil and that a can to be filled and adapted to contain a quantity of oil equal to the quantity contained in the reservoir, has been placed in posit-ion beneath the reservoir, it will be understood that the elevation of the valve stem F will withdraw the valve head from its seat, and, by the encounter of its bossF with the head plate 01 will also lift the reducer from its seat, so that the parts occupy the position shown in Fig. 3, whereupon a full head of the liquid contents of the reservoir will be discharged through the conduit B, the liquid passing into said conduit both through the space exterior to the pipe D and through the bore of said pipe D The full discharge is permitted to continue until the liquid in the receiving can has reached a predetermined level,-*Whereupon, to avoid splashing and overflowing of the liquid in the filling of the remaining or unfilled portion of the can,-the valve stem F is lowered sufficiently to effect the seating of the reducer as shown in Fig. 4, the result of which is to reduce the diameter of the liquid outlet to the diameter of the bore of the reducer and of the pipe D", and, thereupon, the remaining oilcontained in the reservoir is discharged through said reducer bore and the pipe D in a stream which, though small, is of the full size of the pipe D and will therefore be discharged directly and accurately through the center of the can opening. I

The Valve stem may be operated in any desired manner. The arrangement illustrated in Figs. 1 and 2 of the drawings is, however, adapted to the-purpose and one which'I employ.

G is a Windlass wheel having a crank handb 9, and mounted in such position within the reservoir that its periphery is in line above the valve stem, and G is a fiexlble connection between said stem and Windlass. By the throw of the handle g in one or the other direction, the elevation or depression of the valve stem will be occasioned.

In the drawingsl have shown the reservoir as provided with an enlargement H to receive the wheel G.

From an examination of the construction described and illustrated it will be understood that the reducer may be regarded as an auxiliary funnel adapted to be seated within the funnel bottom of the reservoir, and adapted to reduce the size of the outlet of the funnelbottom without altering its character or operation.

The skeleton frame serves both as a device to be engaged by the valve stem for the elevation of the reducer,and as a device to guide the reducer, in its descent, accurately to its seat.

Having thus described my invention, I
