rrnn STATES PATENT IMPROVEMENT IN LIQUID-MEASURES,

' Specification forming part of Letters Patent No. 188,188, dated March 6, 1877 application filed June 24, 1876.

To all whom it may concern Be it known that I, MARGIUS G. RICHARDS, of Oswego, in the county of Kendall and State of Illinois, have invented a new and useful Improvement in a Liquid-Measuring Device, which is fully described in the following specification, reference being had to the accompanying drawings, in which- Figure 1 represents a side elevation of the apparatus; Fig. 2, a vertical section of the same Fig. 3, a plan View of the device; Fig. 4, a cross-section taken on the line :2: m, Fig. 1; Fig. 5, a cross-section taken on the line y Fig. 1; Fig. 6,'a vertical "section taken on the line 2 2, Fig. 4; Fig. 7 a perspective view of the pump-valve Fig. 8, a perspective view of the plunger and regulating device; Figs.

9 and 10, detail views of the regulating-ring,

and Fig. 11, a detailed view of the bottom of the stand-pipe, the casing being partly broken away to show the valves'in the interior.

My invention relates to a device by means of which the liquid contents of the barrels, casks, and other vessels may be drawn out in measured quantities, so that any given quantity within a certain limit may be drawn from the same without the use of the ordinary measuring-vessels.

The invention consists in an arrangement of chambers and pipes, so that as the liquid is pumped from the vessel it fills the main chamber and the stand-pipe therein, from which the liquid is afterward drawn by forcing a plunger a certain fixed distance below the liquid in said stand-pipe, which produces a siphon-like operation, as hereinafter described, and also in various devices, in details of construction as will be hereinafter fully set forth.

In the drawings, A represents the main vessel or chamber, within which is placed a stand-pipe, B, which passes up through the cover of the vessel, and is open at the top. At the bottom of this stand-pipe are small holes a, which provide a communication between the stand-pipe and chamber A. These apertures are constructed by hinged valves 1) inside the stand-pipe, which are held open by suitable springs, except when sufficient pressure is applied inside of the stand-pipe to close them. Upon the top of the receiving-chamber A is a small supplementary chamber, 0, from which a pipe, D, extends down through the chamber A, and projects below the bot- .tom of the latter, so that it may be inserted in the bung-hole of the barrel or cask. A

screw, (1, is attached to the lower end of this pipe, which is secured into the bottom of the barrel or cask, so that the apparatus is held in place whenever the pump is Worked. The

pipe D is fitted with an ordinary valve piston and rod, (1, by means of which the liquid is raised from the vessel containing it into the chamber (l.' The pump-pipe D extends through a supplementary pipe, M, nearly to the top of the chamber .0, so that the latter may be nearly filled without any return flow into the barrel. The opening into the chamher 0 at its top is closed by a suitable stop per, which is constructed so as to serve also as a drip-cup, through which the pump-piston flowing into the stand-pipe B and chamber A- In the upper part of the stand-pipe B, a little be low the opening 0, and opposite thereto, is V will stand at the same height in both.

another aperture, 0, which opens into awastepipe, E, by means of which the liquid flows back into the barrel when it reaches a heightin the stand-pipe even with the top of the chamber A, so that the latter is filled. At

this point there is also a small opening, a, which establishes communication between the stand-pipe and receiving-chamber at the ex treme top of the latter. The waste-pipe E passes out of the vessel A by the side of the pipe D, so as to be inserted in the bung-hole of the barrel with the latter. It is also provided with supplementary sections E, by means of which its length may be adjusted to suit vessels of different capacity. w

Within the stand-pipe B is another pipe, F,

which extends up within the stand-pipe to a point a little above the opening into the chamber O. The lower end f of this pipe passes Enron through the'bottom of the vessel A, so as to form an outlet-pipe, and is bent outward, as

shown in the drawings, so that the receivingthe stand-pipe the packing will be forced outward to fit the stand-pipetightly. In the top of the piston are a few small holes, as shown in Fig. 8 of the drawings. On one side of this plungerpipe G is attached a small tube, g which communicates with the interior of the pipe G at the extreme top of the latter, and extends down upon the outside thereof to a point just above the piston ,9 inside of the stand-pipe. The plunger Gr passes up through a ring-cap, H, which closes the top of the stand-pipe B, and is secured thereto in any suitable manner. The plunger G is provided with a series ofribs, 9 upon its periphery, arranged spirally, as shown in Fig. 8 of the drawings. In the cap His a series of recesses, 71., of such size that the ribs g may. pass down within them. Just above the cap H is placed a loose ring, I, heldto the cap by lugs on the latter,, as shown in Fig. 8' of the drawings. This ring I has a large recessfl, somewhat widerthan the space occupied by the recesses h in the cap B. It also has another smaller recess, '5, within which'tube g is fitted. The tube g prevents the ringI from turning; but the ca-pH is recessed i here the tube g passes through it, so that whenfreed from the ribs g the cap may be turned back and forth a limited distance. This adjustment. of the cap is efl'ected by pulling up the plunger until the ribs 9 are above the ring, where ,it may be ad usted in relation to the 1 ring I, so as to leave one or more of the recesses in the cap exposed, as may be desired.

The ribs 9 on the plunger operate as a kind of graduated scale, for by the construction and arrangement of devices above described it will be seen that if but one notch in the cap H is left exposed only the lower rib of the series can pass through the cap H,'the next Ilb above acting as a stop .to prevent the further depression of the plunger; but the plunger being free to turn within'the cap, and carrying the ring I around with it, if it is turned so as to expose two notches in the cap H, then the plunger may be forced down within the stand-pipe a distance represented by the two lower ribs 9 and so on, until, if the entire series of notchesis exposed, the lunger may be depressed within. the standipe to its utmost extent.

The pump-valves which I use are of peculiar construction, as shown in Fig. 7 of the drawings. A perforated disk, J, is provided upon its lower face with a yoke or loop, j.

tion heretofore described will permit.

The valve-disk K, which may be of leather or any other suitable material, is placed just above the disk J, and a holding-rod, L, passed down through both disks and the yoke j. The lower end of the rod is threaded, and the valve is secured thereon by a. nut turned up tightly against'the yoke. When this construction is used for the piston-valve the attachment is made directly to the piston-rod, as shown in Fig. 2 of the drawings; but for the stationary valve at the lower end of the pump-stock a separate bolt, L, must be used, the lower end of which is extended some distance below the yoke, and, being threaded,

forms the means of attaching the pump to the bottom of the barrel, as heretofore described. The pump-pipe D is held in place by means of a set-screw, 70,011 the vessel A, which engages with a projection, l, on the pipe, as

shown in Figs. 1 and 2 of the drawings.

The pump-pipe may be entirely removed, if desired, by withdrawing it through the opening on the top of thechamber O.

. Upon the outside of the vessel A, near the spout of the outlet-pipe F, is fastened a series of books, N, for the support of vessels underneath the spout, if desired.

The operation of my invention is as follows:

' The liquid. ispumped from. the cask or barrel until the vessel-A is full, and as the standpipe B communicates with the vessel the liquid willlstandlatthe same height within the latter. 1 The plunger G is drawn up until the piston is above the liquid within the stand pipe. When it is desired to draw from the vessel A the plunger is depressed within the stand-pipe to such a distance as the gradua- This movement closes thevalves at the bottom of the stand-pipe, and forces the liquid within said pipe up the small annularspace between the plunger G and the outlet-pipe F until it reaches the top of the latter, whenit flows over. into the pipe Fand out at the spout. At'the same time a small portion of fluid will be forced up in the stand-pipe, above the piston g, through the holes in the top of the latter, and. by this means the lower end of the air-tube g is closed, so that no air can reach the upper portion of the plunger'pipe, and the air having been nearly all forced out in advance of the fluid by the depression of the plunger, it is obvious that a siphon is obtained, the lower end of the outlet-pipe being below the lower end of the stand-pipe.

The operation will. continue so long as liquid stands above the piston in the stand-pipe, the flow being in the direction of the arrows from the vessel A into the stand-pipe, through holes at the bottom of the latter, up through the plunger-pipe G into thepipe F, from which it is emptied at. the spout. The liquid in the stand-pipe will be at the same height as it is-in the vessel A, so that as it is drawn from the latter it will also settle in the former, until finally the lower end of the air-tube g is exposed, through which air is immediately admitted to the top of the pipe G, when the operation of the siphon is immediately stopped, and the outflow of the liquid ceases.

The ribs 9 onthe plunger are arranged so that the latter is graduated for pints, quarts, gallons, or any desired measure, and if the graduation is accurate, only the quantity indicated by the number of ribs passing through the cup in the depression of the plunger will be drawn out from the vessel A.

If the vessel A is not emptied by the first draft a second one may be made at any time thereafter by simply pulling up and turning the plunger, so that an additional gage rib or ribs will pass down through the cup.

I have shown and described my invention in connection with a pump but it is evident that the measuring device may be used in any other connection, without a pump, if desired, the liquid being introduced into the vessel A by any suitable means.

It is evident that the construction and arrangement of pipes for producing a siphonic action may be changed without departing fromthe principle of my invention for instance, the stand-pipe may be enlarged so as to serve as the receiving-vessel, the piston on the plunger being correspondingly increased in size, and the plunger-pipe maybe prolonged and bent to form a regular siphon-pipe, in which case an independent outlet-pipe would be unnecessary. These modifications, however, would not be so convenient to operate as theconstruction and arrangement heretofore shown.

The air-tube g at the side of the plunger,

may also be dispensed with, if desired, for it is evident that when the liquid in the standpipe falls below the piston on the plunger air will be admitted at the top and sides of the piston, and thus the action of thesiphon suspended.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
