LIQUm-MEASURING VESSEL.

SPECIFICATION forming part Of Letters Patent N0. 450,383, dated April. 14, 1891.

Application filed August 25, 1890. Serial No. 363,021- (No model.)

To all whom, t may concern.-

Beit known that I, DAVID E. WOLFF, a citizen of the United States, residing at Hagerstown, 1n the county of Washington and State of Maryland, have invented certain new and useful Improvements in Graduated Measuring Devices; and I 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 appertains to make and use the same.

My invention consists in a new and improved combined pumping, lling, and measuring apparatus, which will be hereinafter fully described and claimed.

Referring to the accompanying drawings, Figure 1 is a side view, partly in section, of the complete apparatus. Fig. 2 is afront View of the upper part of the apparatus. Fig. 3 is a detail view on an enlarged scale, hereinafter referred to. Fig. .5a is a sectional view taken on line a d of Fig. 3. Fig. 4is a similar view of a slightly-varied form, hereinafter described.-

The same numerals of reference indicate correspondingl parts in all the figures.

Referring to the several parts by their designating numerals, 1 indicates an upright supporting-frame, which is secured upon the platform or iiooring 2. Upon a bracket 3 at the upper end of this supporting-frame is mounted -a reservoir 4. The reservoir is provided with the usual gage 4t.

To the rear of the frame 1 is arranged a pump 5, the spout of which is connected by a pipe 6 with the upper part of. the elevated reservoir. To the lower part of the pump is secured the upper end of a tube 7, the lower end of which communicates with the lower reservoir or source of supply, usually a barrel, as 8, arranged belowthe platform 2. The bottom of the reservoir 4 communicates through a neck 9 with the top of a vertical.

measuring-cup 10, the passage of liquid from the elevated reservoir to the cup being controlled by a valve 11 in the neck 9. The inclinedbottom of the cup 10 in like manner communicates with the top of a smaller measuringcup 12,beneath which is arranged a smaller cup 13, and beneath that a still smaller cup 14. A valve 11 is arranged at the bottom of each vertical measuring-cup in the neck 9 at the lower end thereof, and the end of each valve-stem 11L is extended and has secured upon it an eccentric-disk 11b. A separate air vent or tube 15 leads from each neck 9below the valve arranged in said neck and extends out and then up until its open upper end is on a level With the upper end of the elevated reservoir 4. Each air-tube 15 is provided with a valve 16, and the upper end of this valveshaft has a ring 17 secured to it, in which the eccentric-disk 11b on the extended end of the valvefstem 11L tits and turns. These valves 11 and 16 are so arranged with relation to each other that when the valve 11 is turned shut the valve 16 in the air-tube 15 will, through the connecting-link 17, be opened.

When it is desired to measure off the quant-ity of liquid which the smallest and lowermost measure 14 will contain, the valve at the bottom oi' this cup is closed and the valves in the necks of the other measuring-cups are opened, allowing the liquor to run down from the elevated reservoir into the lower measure. When this measure is full, the valve 11 above it is closed and the valve at the bottom of the cup 14 opened. As the valve 11 at the top of the cup 14 is turned to close it, thus shutting off the ilow of further liquor into this cup, the valve 16 in the lower air-tube 15 is opened through the connecting-link 17, thus opening the air-vent and allowing the air to enter into the lower measure 14 as the liquid runs out of the same.

In Fig. 4 I have shown waA slightly-varied form of valve construction in which the top of each measuring-cup is provided with a short air tube or vent 18, and the end of the valverod 11n is extended, passes through this short tube, and has a valve 16 mounted on it within the air-tube, the two valves 11 and 16 being so arranged with reference to each other that when one is closed the otherpis opened, and vice versa.

- To the top of the reservoir is connected the upper end of an air and overflow pipe 19, the lower end of which communicates with the lower reservoir 8. By this arrangement this pipe acts as an air-vent while the liquid is being pumped into the reservoir, and if too much liquid is pumped up into the reservoir IOO it will run over through this pipe and be conducted by it back into the lower reservoir, as will be readily seen.

2O indicates an adjustable bracket sliding vertically on the recessed lower part of the supporting-frame l. This bracket is raised and lowered through a lever 21 and connecting-link 22, and upon its upper face, around which an annular iiange 23 is secured, is seated the vessel 24, into which the liquid is to be measured. This bracket is provided with a flexible drip-tube 25, which runs down and connects with the pipe 19, so that if the vessel 24is overrun or any drippings fall from the lower measuring-cup they will run down through this tube back into the lower reservoir S-and will thus be saved.

From the foregoing description, taken in connection with the accompanying drawings, the construction, operation, and advantages of my invention will be clearly understood.

It will be seen that my new and improved combined apparatus is comparatively simple in construction and very eflicient in its operation and will effectually prevent all leakage and waste whatever.

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

of valves operating simultaneously, one clos-V ing when the other opens, substantially as and for the purpose set forth.

2. In a liquid elevating and measuring apparatus, the combination of a pump connected with the source of supply or lower reservoir and with the place of delivery or upper reservoir by pipes, the upper reservoir for receiving the elevated liquid', a series of meas-V uring-cups connected with the bottom of the upper reservoir, each provided with a vent and valves, as described, and an overflow and waste-preventing apparatus having pipe-connection with the lower and upper reservoirs, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

DAVID E. WOLFF.
