MEASURlNG-FAUCET.

SPECIFICATION forming part of Letters Patent No. 249,134, dated November 1, 1881.

Application filed July 6, 1881.

To all whom it may concern Be it known that I, FREDERIC T. WILLIAMS, of De Wittville, in the county of Chautauqua and State of New York, have invented certain new and useful Improvements in Apparatus for Drawing and Measuring Liquids; and 1 do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanyingdrawings,which form part of this specification.

My invention relates to-an improvement in apparatus for drawing and measuring liquids and it consists ofa transparent graduated meastiring-chamber of peculiar form, attached by a suitable delivery-pipe to the discharging end of a siphon, said pipe being provided with a suitable three-way cock for regulating the tilling and emptying of the chamber.

It further consists of a device for clamping the said chamber in position and giving vent to both the said chamber and the barrel or reservoir to which the apparatus is attached,a device for registering each emptying of the measuring-chamber, and a device for exhausting the air from the siphon.

The object of my invention is to provide an apparatus which will by a simple movement draw, measure, register, and deliver liquids from a barrel or reservoir into any ordinary open or close mouthed vessel.

Figure l is a side elevation of the apparatus attached to a barrel, the sides of the exhaustcylinder and barrel being broken away. Fig. 2 is a front detail view, showing a portion of the registering device. Fig. 3 is a partial plan view of the registering-wheel and operating mechanism. Fig. 4 is an enlarged sectional diagram of the clamping-screw and adjacent parts upon the vertical plane passing centrally through the machine from front to back. Fig. 5 is an enlarged section of the three-way cock and adjacent parts upon the same plane as Fig. 4. p

The measuring-chamber A rests upon a hollow seat, B, and is clamped in position by the hollow thumb-screw O, which thumb-screw (3 turns in the frame F and presses upon the cap (ModeL) J, holding both the cap J and chamber A in position. ,The chamber Ais apertured at the top and bottom, and rubber or other suitable packing is placed between the seat B and chamber A, and between the chamber A and cap J, to prevent leakage.

The frame F is right-angled at the point F, and fastened at the lower end to the spout or termination 1) of the pipe E in front, and the upper end to the siphon-pipe G at the back.

On the top of the frame F, near the siphon G, is placed an upright cylinder or pipe, H, extending upward to the level of the highest part of the siphon G,which pipe H is furnished with a piston, I, and is connected with the pipe E by a small exhaust-tube, K, through an aperture in the frame F.

The filling and emptying of the chamber A is regulated by the use of the three-way cock T at the junction of the hollow in the' seat B with the pipe E. The said three-way cock T is so constructed that when the handle Q is turned to the right to a certain point there will be an open communication between the siphonpipe G and measuring-chamberA through the pipe E, while the passage from the chamber A to the spout D remains closed. Turning the cock T to the left to a certain point cuts off the former or supply passage and opens thelatter, allowing the liquid to discharge from the spout D. When turned midway between the two points mentioned the cock T cuts off both the supply and discharge. Alug or projection upon the plug of the cock T, or an equivalent device, is made to act as a double stop to prevent turning the cock T too far in either direction.

The chamber A is given vent through the vent-tube M, which is joined to the cap J, passes through the hollow thumb-screw G, and termnatesinside of the barrel or reservoirL, through the bung or cover of the same. The siphon G passes also through the bung .or cover N and terminates at or near the bottom of the vessel L.

At some point in the vent-tube M, preferably at O, is made an orifice normally closed by a pivoted pad, P, and spring S. The pad Pis connected with the cock T by a wire, R, and

elbow-lever V or equivalent device in such a manner as to raise the pad P and open the orifice when the cock T is in position for discharging liquid from the chamber A.

The chamber A is preferably constructed of glass, and its form is nearly that of an inverted turnip, that form being advantageous for two reasons: first, its near approach to the spherical form makes a chamber of given capacity require but asmall space as compared with ordinary forms of graduated measures; sec ond, beingofsmall diameter near the top,where small quantities are graduated, such quantities are more accurately measured than would be practicable with a cylindrical chamber. The chamber A is constructed to hold a definite quantity-as one gallon-and fractions of such quantity are marked in a scale, A, upon the side of the chamber A, the quantities indicated by said scale A increasing from the top downward. Graduating the scale A from the top downward enables the operator to alwaysleave the chamber At'ull or filling, and in readiness, when required, to draw oif any desired quantity.

The apparatus may be attached to a barrel by a rod, Z, with right and left screws turning in two blocks or heads,UW, and forcing them apart between the chines ot' the barrel. The siphon-pipe G, passing through an arm or projection upon each of the heads U YV, holds the apparatus in position, as shown.

Having entered the apparatus into and attached the same to a barrel or reservoir containin g liquid, substantially as shown, the cock T is turned to the left to close the passage from the siphon G through the pipe E. The piston I is then somewhat forcibly drawn to the top of the pipe H, thereby exhausting the air from the siphon G through the exhausttube K. The siphon G will then fill with liquid from the vessel L. A stopper may be inserted in the top of the pipe H, to prevent evaporation, or the piston I may be left in instead. The cock T is then turned to the right, opening communication from the siphon G to chamber A, closing the outlet passage to spout D and slackening the wire R. The pad P then closes the aperture 0 by the action of the spring S. The liquid then flows from the vessel L through the siphon G and fills the chamber A, the air in the same passing at the same time through the vent-tube M into the vessel L. The chamber A having filled, the apparatus is ready for drawing 011 the liquid, and is designed to be left in that condition when not in operation.

To draw off any desired quantity of liquid the cock T is turned to the left, cutting off the supply to and permitting the liquid to discharge from the chamber A through the spout I), giving vent to the chamber A at the same time through the tube M and orifice O, the pad P being raised by the wire B. When the desired quantity has been discharged, if less than the full capacity of the chamber A, it will be shown by the height of the surface of the liquid upon the graduated scale A when the cock T should be turned back to its former position, and the chamber A will fill as before.

If more liquid is desired to be drawn than the full capacity of the chamber A, the operation is repeated until the required quantity is obtained or the. contents of the vessel L exhausted.

Each discharge of the chamber A is registered by the wheel a revolving in a horizontal plane upon the seat B as a pivot, having aseries of figures upon its periphery, each of which figures is brought to view in succession at the opening I) in the frame F, the wheel a being moved forward one figure at each discharge by the sliding bar or frame 0, having a dog or wedge at either end, which work alternately in a series of slots through the rim of the wheel a, each dog or wedge turning the wheel onehalf the distance between the figures upon its periphery at each forward and backward movement of the cock T, the bar 0 being actuated by a spur or segmental gear, (1, upon the plug of the cock T, engaging the teeth of a rack, 0, upon the sliding bar 0.

The head W may be made solid with the frame F, extending back of the siphon G, and, if preferred, the chamberA maybe constructed wholly or only in part transparent, and equivalent devices may be substituted for several parts of the apparatus without departing from my invention.

Having thus described my invention, I claim- 1. The combination of the barrel L with a drawing and measuring apparatus provided with the siphon G and vent-tube M, both of which pipes pass into the barrel through the bung-hole, and a clamping device which secures the apparatus to the end of the barrel, substantially as shown.

2. The combination of the pipe E, seat B, cock T, and wheel (I with a slide which. operates a registering mechanism, substantially as described.

3. The combination, with the siphon G, of a measuring chamber, A, receiving and discharging liquids through the same aperture, and the pipe E, constituting the supplyingpipe for the said chamber A, substantially as shown and described.

4. The combination, with a siphon, G, and measuring-chamber, A, of the pipe H, furnished with a solid-head piston, I, and connected with the pipe E by the exhaust-tube K, substantially as shown.

5. In combination with a measuring-chamher, A, the vent-tube M, connecting the interior of the chamber A with the interior of the barrel or reservoir L, the aperture 0, pad P, and spring S, the pad being connected with the cock T by suitable mechanism in such a manner as to open and close the orifice O by the movements of the handle Q, substantially as and for the purpose set forth.

6. The hollow thumb-screw O, in combination with the cap J, chamber A, pipe M, and frame F, substantially as shown and described.

7. In combination with a measure, A, the registering-wheel at, having a series of figures upon it, each of which figures is brought into view in turn at a given point by the action of two sliding wedges acting upon said wheel substantially" as shown.
