LIQUID-MEASURING APPARATUS.

4 SPECIFICATION forming part of Letters Patent No. 753,283, dated. Marbh 1, 1904.

To all whom it may concern:

Be it known that I, THOMAS EVERETT MATHER, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Liquid- Measuring Apparatus; and I do hereby declare the following to be a full, clear, and exact description of theinvention, such as will I enable others skilled in the art to which it ap.

pertainsto make and use the same.

My present invention has for its object to provide a simple, cheap, and eflicient device for rapidly'measuring liquids; and to this end it consists of the novel devices and combinations of devices hereinafter' described, and defined in the claims. 7

The invention is illustrated in the accompanying drawings, wherein like characters in- 29 dicate like parts throughout the several views.

tank, which communicates through a supplypipe 6 with the receiving end of the pipe 4 outward of the valve 4.

The delivery end of the delivery or discharge ing pipe 4: terminates in a valve-seat 7 in 5 5 which is swiveled an elbow-like'valve 8. An oscillating delivery pipe or tube 9 communicates with and is carried by the elbow portions of said valve 8. A valve-actuating rod or arm 10, shown as oftubular form, is also carried by the elbow portion ofthe valve 8 and projects in a diametrically opposite directio'nfrom a tube 9. A valve-actuating dog 11 is loosely pivoted on the rod or arm 10, as best shown in Figs. 4 and 5. Said dog is provided 5 with a weighted arm 12, which yieldingly holds the same in a horizontal position. T (Best shown in Fig. 4.) The dog 11 is free to move in one direction, but is held against movement in the other direction by cooperating stops 13 and '14; respectively, on the said dog and on said rod 10. The purpose of this dog will pres- The valves l and 1' are provided with reversely curve'd cam-arms 15, with which the dog 11 cooperates .in, a manner to be set forth in the description of the operation. The valve 4 is provided with an arm 16, towhich the lower end of a link 17 is pivotally connected, as best shown in Fig. 1. Valve- seats 18 and 19 communicate, respec- 8 tively, with the tops of the compartments 1 and 1, and the three compartments 1, 1", and

1 are in communication at. their tops through an air-tube 20, which opens at its intermediate portion into said compartment 1 and 5 at its ends into the lower ends of the valveseats 18 and 19. The valve-seats 18 and'19 are provided, respectively, with rotary valves "or stop- cocks 21 and 22, one of which stands in an open position while the other is closed, 9 and vice versa. Air- venting pipes 23 and 24,

respectively, lead upward from the valve- cases 18 and 19. The upper end of the ventingpipe 24 opens into an enlarged head 25, provided at its upper portion with air-holes 26. The bottom of the head 25 is preferably inclined, as shown in'Fig. 1, and the pipe 24 is provided just above said bot-tom with perforations 27, through which the water may run back from said head and said tube. For I9 9 by a chain or other flexible connection 30.

dog 33. the dog 33 is gravity-held against a stop-pin racy ofthe measuring device.

The said tube 9 is also provided with a projecting cam-pin 31, which acts upon the free end of the arm 28, as will be hereinafter described. The link 17 which is connected to the valve-arm 16, is pivotally connected to the valve-arm 29. The said arm 29 is provided with a projection 32, towhich is pivoted a In the normal positions of the parts 34 on the projection 32, as shown in Fig. 1. The oscillating delivery-tube is further provided with a second cam-pin 35, which acts upon the arm 29 andupon the dog 33 thereof to oscillate the valve 22 in a manner presently to be described. Stops 36 and 37 on the side of the tank 1 limit the return movements of the valve- arms 28 and 29, respectively.

Operation: Normally the parts stand as shown by full lines in Figs. 1, 2, and 3. Directing attention to Fig. 3, it Will be noted that the valves 4, 4, 4, and 22 are open,

while the valves 8 and 21 are closed. It is evident that in these positions of the valves the liquid from the supply-tank 5 will freely flow into the several compartments 1 1 1 of the measuring-tank 1 and will fill the same,

since'the air is freely exhausted therefrom through theopen valve 22 and vent-pipe 24. It is also evident that the liquid will risewithin the said tube 24 iii-seeking its level Within the supply-tank 5. If five gallonsto wit, the entire contents of the several compartments of the measuring-tank 1are to be measured out, the valves 4 and 4 are left standing open, with their arms 15 positioned as shown in Fig. 1, and the delivering-tube 9 is simply oscillated-from its normal position (indicated by full lines in Fig. 1) into the position indicated by .dotted lines in said view and by full lines in Fig. 4. This movement of the said delivery-tube, it will be noted by reference to Fig. 4, opens up the valve 8, so

that the liquid will freely runout through the said delivery-tube. It will, however, be noted that the said same movement of the deliverytube causes the cam-pin 35 thereof to engage vthe dog 33, and thereby force the valve-arms 16 and 29 into the positions indicated by dotted lines in Fig. .1, in which positions the two valves 4 and 22 are closed. The closing of the supply-valve 4 cuts ofi the supply of liquid whilethe measured liquid is being discharged, and the closing of the valve 22 prevents the downflow of the liquid contained in the vent-pipe 24, and thus insures the accu- Again, the latter part of the downward movement of the delivery-tube 9 after it has closed the two valves 4 and 24 draws upon the chain 30 and moves the valve-arm 28 into the position indicated by dotted lines in Fig. 1, and thereby opens the vent-valve 21. Thus it will be seen that the liquid will not begin to run from the delivery-tube 9 until said tube has reached approximately its extreme lowered position. After the measuring-tank has been emptied or the predetermined amount of liquid drawn therefrom the delivery-tube 9 is turned back to its normal position, under which movement its cam-pins 31 and 35 .acting, respectively, on the valve- levers 28 and 29, close the ventvalve 21 and again open the vent-valve 22. It will of course be seen that the supply-valve 4" will be opened simultaneously with the opening of the vent-valve 22, since the arms of the said two valves are connected by the link 17 It will also be understood that the dog 33 will freely swing under the return movement of the delivery-spout to permit the cam-pin 35 to pass by the same and into engagement with the valve-arm 29,. If but one gallon of the liquid is to be measured and drawn 013?, the valve 4 should be closed before turning down the delivery-spout 9, while if two gallons are to be drawn OK the valve 4 'should be left open and the valve 4 should be closed. The said valves are closed by hand or by operating the levers 15. When one of the said valves is closedfor instance, the valve 4?its lever 15 will stand as indicated by dotted lines in Fig. 1. in which position it stands in the path of movement of the dog 11. This being the case, when the delivery-tube 9 is turned downward the said dog swings freely to clear the same; but as said dog cannot swing in an opposite direction it will when the said tube 9 is turned back to normal position engage the said valve-lever 15 and cam the same back to normal position and close the valve. In this way the valves 4 and 4 are always automatically restored to their normal open positions by the return movement of the deliverytube.

As is clear from the above description, the valve 22 in the vent-pipe 24 is opened up to permit air to be exhausted from the measuring-tank and the said tank to be filled with the liquid, while thevalve 21 in the vent-pipe 23 is opened up to permit air to flow into the said tank and the said tank or certain'compartments thereof to be emptied. When air is forced upward through the pipe 24 while the said pipe is filled or partially filled with liquid, the liquid therein will be caused to bubble up and overflow the upperend ofthe said pipe, but will be caught by the expanded head 25 and will flow back into the pipe 24 when the valve 22 is opened.

A liquid-measuring apparatus of this character is capable of a great many diflerent uses, but will be found especially serviceable-by grocerymen and other merchants for measuring and dispensing various oils, such as kerosene and gasolene, table liquids, such as vinegar, and even the heavier liquids, such as molasses and syrup.

It will of course be understood that the device is capable of considerable modification as to its details of construction within the scope of my invention, as herein set forth and claimed.
