ROTARY PUMP R MOTOR APPLICABLE ALSO AS A FLUID-METER.
SPECIFICATION formingpart ornate Patent-No. 726,907, dated May 5, 1903.
Application filed May 5, 1 902.. .Serial No. 105,997. (No modeL) To all whom it may concern..- 1' 7 Be it known that I, EDWARD NICHOLAS GU- LIOH, a subject of the King of Great Britain and Ireland, and a resident of 94Lyncroft Gardens, West Hampstead, in the county of London, England, have invented an Improved Rotary Pump or Motor Applicable .also as a Fluid-Meter, ofwhich the following is a specification.
This invention relates to a rotary pump or motor, also applicable for use as a meter for measuring fluids, of the type in which a drum or disk carrying hinged vanes turns within a casing against which the vanes bear. My construction provides an apparatus of this kind which can be made in a very inexpensive manner, iseasily repaired, and possesses great efficiency.
In order that this invention may be more readily understood, reference is had to the accompanying sheet of drawings, in -which Figure l is an elevation of the apparatus with one side of the casing removed. Fig. 2 is a cross-section with part of thedrum removed, and Fig. 3 shows a modified arrange ment of the wings or vanes.
The rotatingidrum A is concentric withthecasing B, both being cylindrical, and in order to close the vanes 0 upon the drum at one point of their travel I provide a metal strip D, curved to form a cresent-shaped division in the chamber and fixed to a projecting block or abutment 19 between the inlet and outlet ports I). This strip D is formed with holes or openings (1, extending toward each end, so that the water flows into or out. of the cylinder through a considerable portion of the circumference, the curved strip forming chambers d at each side of the central division, into which the ports I) open. As the casing anddrum are concentric, the compartments between the hinged blades or vanes remain the same size through a considerable portion of the revolution, .contracting or expanding only while the water is passing in or out. As the vanes pass the central division or block they are completely closed down upon the drum, so that no liquid can pass from one side to the other across the division. I also provide the drum or disk A with a shallow annular groove or channel a, so that a space is left behind each vane when closed, this channel preventing any dirt or grit which may enter the apparatus interfering with the complete closingofthe vanes. A small body of wateris also carried along by each vane when closed,- owing'to this channel, and this assists in providing a water-tight joint for the vanes, more especially serviceable in starting the pump, as this pump canjbe started without difficulty when empty, there being no nocessity for priming. f
The vanes O arehinge'd by solid beads c, at their ends dropping into correspondinglyformed channels in; the periphery of the drum. r
In order to make the apparatusreversible, so that it will act in both directions, alternate vanes may-be placedin a reverse manner, as shown in Fig. 3. This also provides a brake action, as any slip of the water past the rotating drum would act to raise the normally inoperative vanes and bring them into action. A i
If used as a meter, it is to be understood that-the usual counting mechanism is to be attached to the shaft carrying the drum A;
but the apparatus is more especially intende as a pump or water-motor.
What I claim as my invention, and desire to secure by Letters Patent, is-
1. In a rotary pump, motor or meter having a rotating drum within a casing carrying hinged vanes expanding against the casing, a shallow groove at extending completely around the periphery of the drum behind the hinged vanes, substantially as and for the purposes specified.
2. A rotary pump, motor or meter, having a rotating drum within a casing, hinged vanes upon the rotating drum expanding against the casing and arranged to open al't'ernately in the opposite directions, and meansfo'r cl'osing the vanes against the drum,substantially as herein described and shown.
In witness whereof I have hereunto set my hand in the presence of two witnesses.
EDWARD NICHOLAS GULIUH.
