A. DE WITT. MEASURING VESSEL.

Patented Aug. 13, 1889.

UNITED STATES PATENT OFFICE.

ABRAHAM DE IVITT, OF BLUFFTON, INDIANA.

MEASURlNG-VESSEL.

SPECIFICATION forming part of Letters Patent No. 409,023, dated August 13, 1889.

Application filed April 9, 1889. Serial No. 806,541. (No model.)

.To aZZ whom. t may concern.-

Be it known that I, ABRAHAu DE WITT, a citizen of the United States of America, residing at Bluffton, in the county of Wells and State of Indiana, have invented new and use ful Improvements in Measuring-Vessels, of which the following is a specification.

My invention has relation to improvements in metallic measuring-vessels of that class or style used for holding a quantity of liquid and adapted to discharge a desired measure of its contents, andthe object is to simplify and improve existing devices of the kind.

I have clearly and fully illustrated my invention in the accompanying drawings, forming a part hereof, wherein-- Figure 1 is a view of the complete vessel. Fig. 2 is acentral vertical section of the same with the delivery-spout turned to discharge the contents. Fig. 3 is a view of the valved plunger or piston. Fig. 4 is a plan view of the lid or cover of the vessel.

A designates the body of the vessel, formed into a true cylinder 1 and provided with a flat bottom 2, and a handle or bail 3 attached to the shell of the vessel, as usual. On the side of the shell is secured a vertically-ar# ranged tube et, which consists of a semicircu* lar shell having its edges sealed by solder to the face of the vessel, so that the shell of the vessel at that part constitutes a part of the interior of the tube. This construction secures the tube rmly to the can and prevents it from being disturbed or displaced by eX- terior influences. I The ends of the tube at the top and bottom are closed exteriorly; but openings 5 6 are formed in the shell at the respective ends, the former of which serves as an exit-port from the vessel to the tube through which the iiuid is forced, and to the latter opening 6 is rigidly connected a pipe 7, the upper end of which projects a short distance above the rim of the vessel, as shown, in order that the end may enter and connect with the swiveled nozzle or discharge-pipe. The fluid on the pressure of the piston or plunger is forced through the opening 5, thence up through the tube on the outside of the shell, through the interior pipe 7, and through the swiveled nozzle into the receiving-utensil.

B designates the lid or cover, which fits snugly in place on the vessel and is provided with a filling-port 8, having a threaded cap 9 fitted thereto. The nozzle 10 consists of an arched or curved pipe, having its one end 1l attached to the cover, so as to turn outward, as seen in Fig. 2 of the drawings, andwhen not in use that it may be swung or turned baclgwith its free end in the drip-well or seat- 12, as seen in Fig. 1 of the drawings. This drip-well consists of a screw-cap fitted in the cover and formed with a hole 13, over which the free end of the nozzle rests when it is turned to that position, yas shown. The hole 1S not only serves to permit the drip to find its way back into the vessel, but also serves as an air-hole to facilitate the filling of the vessel through the iillingwhole. In the center of the cover is a piston-rod aperture let, through which rod l5 of the piston is passed and slides. On the lower end of the piston-rod is secured the piston 16, which has its rim provided with suitable packing 17 to make it fit fluid-tight in the shell of the vessel. The piston is formed with ports 18, and on the under sides are secured valves 19 20, arranged to open and permit the piston to be drawn up and leave the fluid escape below the piston, and to close and seal the ports of the piston when a downward movement takes place. On the piston-rod are marked graduations 2l, which indicate the height to which the piston must be lifted from the bottom of the vessel to discharge a certain quantity of fluid when pushed down again to the bottom.

The functions of the several parts have been stated in connection with their description; but the operation may be rehearsed as follows: W hen it is desired to discharge liquid from the vessel, the nozzle is turned from its position on the cover to an outward position. The piston is then lifted until the measure desired is indicated by the graduation, when the piston is forced down, and the result is the discharge of the required quantity of the contents.

Having thus described my improvements, so as to distinguish them from .other inventions, I proceed to particularly point out and distinctly claim the parts, improvement-s, and combinations.

I claim as my invention as follows:

IOO

I. The combination, with the cylindrical vessel A, provided with the ports :Lt its top and bottom, the tube 4, openinginto the said ports, and the interior pipe 7 on the upper port, of the cover B,provided with a drip-hole and nozzle-sent, the swiveled nozzle in the cover,m1d the valved piston, substmltizilly als described.

2. The combination of the cylindrical vessel A, provided with the pipe 7 at its upper end, and the seinicircular shell or tube secu red on the outer face of the vessel and opening into the Vessel at its bottom and into the pipe at its top,the coverprovided with a d rip-hole and nozzle-seat, the swivelcd nozzle on the Cover, and :L vnlved piston provided with L piston-rod having graduations of measures marked thereon, substantially as described, and for the purpose specified.

In Witness whereof I hereunto set myhand 3o in the presence of two attesting witnesses.
