MEASURINGDEVICE.

SPECIFICATION forming part of Letters Patent No. 559,386, dated May 5, 1896. Application filed April 1, 1895. Serial No. 543,970- (No model.)

To all whom it may concern:

Be it known that I, SAMUEL OTIS J ONES, of Stillwater, Washington county, Minnesota, have invented certain Improvements in Measuring Devices, of which the following is a specification.

My invention relates to improvements in measuring devices for liquids and like substances which flow freely, adapted to be connected to a source of continuously-flowing supply and to be operated to receive and discharge a predetermined quantity; and it consists in the construction and combination here inafter particularly described and claimed.

In the accompanying drawings, forming part of this specification, Figure 1 is a longitudinal central cross-section of my device provided with two measuring-passages, and Fig. 2 is a vertical cross-section taken on line a a of Fig. 1. Fig. 3 is a longitudinal central crosssection of a modified form, showing the measuring-passage provided with a movable piston, the full-line position showing the passage in registering position with one pair of inlet and outlet ports, and the dotted-line position showing the passage in registering position with the other pair of ports; and Fig. 4 is a vertical cross-section of the same on line 0 c of Fig. 3.

In the drawings, A, Figs. 1 and 2, represents the outer inclosing cylindrical case, in which is arranged the reciprocating plug or core 2. This core is provided with the transverse cylindrical measuring openings or passages 3 and 4. The top of the case A is fitted with the inlet-conduit 5 and the bottom with the outlet ports or vents 6 and 7. Connected with the core and passing through one end of the inclosing case is the piston-rod 8, having connection with a suitable source of power, (not shown,) by means of which the core is reciprocated to bring its measuring-passages 3 and 4 into alternately-registeringposition with the inlet and outlet ports. Extending longitudinally of the inclosing case, on the inside thereof, is the spline 9, engaging the groove 10 in the core, so as to keep the same from turning when reciprocated in the case. In the operation of this form of my device as soon as the passage registering with the inlet-port is filled the core is reciprocated to bring that passage into registering position with one of the outlet-openings and the other passage into position to register with the inlet-opening, each passage being alternately brought into registering position with the inlet and one of the outlet ports in the operation of the device. It will be evident that each passage at all times during the operation of the device, except when the core is being moved, is being either filled oremptied, thus furnishing an almost continuous discharge.

In Figs. 3 and 4 I show a modified form of my device. In this construction the core 18 is provided with the transverse cylindrical passage or opening 19, in which works the piston 20, serving as a movable or reversible bottom therefor. The sides of the inc-losing case 0 are provided with inlet-ports 21 and 22 and outlet ports or vents 23 and 24, with which the passage alternately registers in the operation of the device so as to be filled and emptied. This form is operated in the same manner as the other form, and is also similarly provided with a spline 25 and groove 26 to prevent the turning of the core. In the operation of this form, with the parts in. the position shown in Fig. 3, the fluid or other matter being measured flows in through the inlet-port 21, forcing the piston to the opposite end of the passage and the matter contained in the passage out through the outletport 23. The core is then reciprocated to bring the passage into registering position with the outlet-port 24, through which it empties and is filled at the same time through the opposite inlet-port 22. The passage thus alternately fills and discharges through the respective inlet and outlet ports as the core is moved in its case.

I claim- 1. In a liquid-measuring device, the combination with the tight inclosing case having fixed and oppositely-arranged inlet and outlet ports, of the measuring device fitted to said case and adjustable longitudinally thereof, and adapted each time it is reciprocated to register with said ports to receive a predetermined quantity through an inlet-port and simultaneously discharge another and similar quantity through an outlet-port.

2. In a liquid-measuring device, the combination with the tight inclosing case provided With oppositely-arranged inlet and outlet ports, of the reciprocating plug or core fitted to said case, and being so chambered and partitioned as to receive apredetermined quantity through an inlet-port and simultaneously discharge a similar quantity through an outlet-port as reciprocated in said case.

3. In a device of the class described, the combination with the inclosing case provided with inlet and outlet ports, of the plug movable in said case, the passage through said plug and the movable partition in said passage constituting ofthe same a pair of similar measuring-chambers adapted to register with the ports in the reciprocating of the core so that one chamber will receive a predetermined measure through an inlet-port and the other chamber simultaneously discharge its contents through an outlet-port.

4. In a measuring device, the combination With the cylindrical iuclosing case provided with inlet and outlet ports, of the plug or core movable in said case, the passage therethrough adapted to be brought into alternately-registering position with said ports, and the partition Working in said passage.

5. In a measuring device, the combination with the cylindrical inclosing case provided with the series of oppositely-arranged inlet and outlet ports of the reciprocating plug or core arranged in said case, the passage therethrough adapted in each reciprocation of said core to register with an inlet and outlet port, and the piston Working in said passage allowing the passage to be filled through an inletport and simultaneously emptied through an opposite outlet-port.

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

SAMUEL ()TIS JONES.
