T 0 all whom may concern.

lie it known that l, lVnnNnn I. STAAF, a resident of Pittsburgh, in the county 0t Allegheny and State of Pennsylvania, hays invented a new and useful Improvement in Liquid-Meters, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part which Figure l is an end elevation, partly broken away, of-a meter embodying my invention; Fig. 2 is a side view, also partially broken away; and Fig. 5 is a sectional view of a portion of the meter.

My invention has relation to liquid ineters, and is designed to provide a meter of simple and eficient character which will measure either the weight or volume of the liquid passing therethrough, and which also has means for recording and indicating the temperature of the water.

The nature of my invention will be best understood by reference to. the accompanying drawings, in which I have shown my preferred embodiment thereof, which will now be described, it being premised, however, that various changes may be made in the details of construction and arrangement of the parts, without departing from the spirit and scope of my invention as defined in the appended claims. y

In these drawings, the numeral 2 designotes a cylinder, having an inlet connection 3 and an outlet connection 4:, tor the liquid to be measured. These connections are at the lower portion of the cylinder at opposite sides; but the inlet orifice 5 is well up toward the horizontal center line of the cylinder, the upper edge of the orifice being preferably at or near such horizontal center line. The outlet orifice 6 also has its upper edge preferably extended up, to the hori- Zontal center line of the cylinder, and its Specification of Letters Patent.

shown at the. right-hand side of Fig. 3, they form relatively deep bucket-s, with upwardly extending, outwardly directed, outer end walls. or flanges. As this flange of each bucket uncovers the upper edge of the inlet orifice 5, a portion of the entering water or a suitable gear Wheel 9, which meshes with another gear wheel 10, the latter driving a flexible shat't 11, which is connected up to and drives a suitable register 12. This register is of any well known form, and may be made to indicate either weight or volume of Rising from the cylinder 2' is a post or column 13, upon which. is mounted a case 14:, containing a recording thermometer 1-5. This thermometer may be off any well known character, and may be driven by clock work, or in any usual way.

' 16 is the thermometric element, which actuates the pencil of the recording thermometer, and which is carried downwardly and into the outlet connection 4 of the meter so as tobe affected y the temperature of the outgoing water;

My invention provides an extremely simple and convenient form of meter, by means of which either the weight or volume of water, or other liquid may be registered, and which will also make a continuous record of the temperature of the water.

What I claim is l-- I 1,. A. liquid meter, comprising a cylinder having an inlet opening at one side and an outlet opening'at the opposite side, a horizontal shalt journaled in said cylinder and extending through one end thereof, blades or buckets carried by the shaft within the cylinder, a vertical column mounted on said cylinder, a meter device supported by said column, gear connections between the movable elements of the meter and the extended end of said shaft, a thermoinetric element extending into the path of flow through said cylinder, and a. recording thermometer 1nstrulnent also mounted on said column, and having an actuating connection with said tllOl'lllOlllGlZl'lC element; substantially as described.

2. A liquid meter, comprising a cylindrical casing, a shaft extending therethrough, a series of bucketshaped blades fixedly connected to said shaft, each of said blades having an outer Wall which extends in an up-- Ward and outward direction when the blade is at the down-going side of the meter, the casing having lateral inlet and outlet openings at opposite sides thereof, at points nearly at the horizontal center line of the shaft, the upper edge of the inlet opening being at a point near the horizontal center line of the shaftand said opening being wider than the adjacent edge of a blade so that liquid will be discharged into the casing above and also below each blade when the latter is adjacent to the center line of the opening; substantially as described.

3. A liquid meter, comprising a cylindrical casing, a shaft extending therethrough, a series of bucket-shaped blades fixedly connected to said shaft, each of said blades having an outer wall which extends in an upward and outward direction when the blade is at the down-going side of the meter, the casing having lateral inlet and outlet openings at opposite sides thereof and at points nearly at the horizontal line of the shaft, the upper edge of the inlet opening being at a point near the horizontal center line of the shaft, said opening being wider than the adjacent edge of a blade so that liquid will be discharged into the casing above and also below each blade when the latter is adjacent to the center line of the opening, and the edges of the blades contacting with the inner wall of the casing throughout their travel between the edges of the inlet and the outlet openings; substantially as described.

In testimony whereof, l have hereunto set my hand.
