ROTARY WATER-M ETER.

SPECIFICATION forming part of Letters Patent No. 673,062, dated April 30, 1901.

Application filed May 2,1900. Serial No. 15,212. (No mOdeL).

in Rotary Water-Meters, of which the following is a specification.

My invention relates to a continually-rotating water-meter, and has especially in view to provide means for preventing an underfilling of the compartments and to insure that each compartment is filled exactly to a certain point before it begins to empty.

My invention is represented in the accompanying drawings, in which- Figure l is a vertical section of the apparatus. Fig. 2 is a scheme of the position of the apparatus at the moment when one compartmentis perfectly filled. Fig. 3 is a scheme of the same at the moment when this compartment begins to empty.

The invention relates to that class of watermeters in which a bucket-wheel is employed,

which is caused to rotate by the gravity ofthe water. The buckets are formed by several plates a, fixed between two disks 5, one of which is shown in the drawings, which disks are turnable around the axial inlet-pipe 0, so that a drum is formed which can rotate around the axial inlet-pipe c. The plates at are curved from the periphery of the disks b toward the axle c and are situated in such way that they do not touch each other. The space left between them near the periphery is very small and serves as outlet for each respective compartment. These outlets are arranged in such way that the water of each compartment does not yet flow out when the supply to this compartment is stoppedthat is to say, when the compartment is filledso that after the compartment is perfectly filled the drum must rotate farther before the compartment begins to empty.

In Fig. 2 the compartment is shown perfectly filled, while in Fig. 3 the position is shown in which it begins to empty. During the time the drum rotates from the position shown in Fig. 2 to that shown in Fig. 3 that part 70, Fig. 2, near the periphery lying between the level of the water and the outlet fills with water. Now this quantity of water used for filling this room is smaller than the quantity of water contained in the room Z, Fig. 3, lying between the level of the water of the compartment near the axle at the moment when the compartment is filled and the level of the same when the compartment begins to empty, whereby it is attained that during the time the drum rotates from the position shown in Fig. 2 to that shown in Fig. 3 a certain quantity of water must flow from this compartment into the following one, so that each compartment is at first overfilled, and then the surplus water flows into the next compartment before the first compartment begins to empty. Only by this overfilling of the compartments the exactitude of my wa- 'ter-meter is attained.

The water enters the apparatus through the inlet-pipec, which is provided with a slot d, situated at an angle of substantially forty-five degrees to the vertical diameter. This, as well as the fact that the outlet of each compartmentis situated in such way that the compartment can only begin to empty after the supply thereto has stopped some time before and that the cubic content of that part of the small space left between the plates near the periphery lying between the level of thewater in the moment when the supply to the compartment is stopped and the outlet is smaller than the cubic content of that part of the compartment near the axle lying between the level of the water in the moment when the supply to the compartment is stopped and the level of the water at the moment when the compartment begins to empty, forms the object of my invention.

What I claim as my invention, and desire to secure by Letters Patent of the United States of America, is

A continuously-rotating water-meter in the form of a drum provided with an inlet-pipe at its center, and consisting of several plates fixed between two disks turnable around said inlet-pipe, said plates being curved from the periphery toward the axle, so as to leave only a small space between them near the periphery, the arrangement being such that the eubical contents of that part of the same small space lying between the level of the water at the moment when the supply to the compartment is stopped, and the peripheral outlet is smaller than the cubical content of that part name to this specification in the presence of of the compartment lying between the level two subscribing witnesses.
