H. E. KLEFFEL APPARATUS FOR DELIVERING AIR TANGENTIALLY TO AN AIR REGISTER Filed Sept. 24, 1923 INVENTOR HARRISON E. KLEFFEL HIS ATTORNEY Patented Dec. 16, 1924 UNITED STATES [PATENT OFFICE.

HARRISON KLEFFEL, NEW YORK, N. Y.

I Application filed September 24, 1923, Serial No. 664,518. L

i To all whom it may concern:

Be it known that I, HARRISON E. KLEFFEL,

.a citizen of the United States, residing on Manhattan Island, in the city, county, and

State of New York, have invented-certain new and useful Improvements in Apparatus for Delivering Air Tangentially to an Air Register; and I do hereby declare the following to bea. full, clear, and exact description of the "invention, such'as will'enable others skilled in the art to which it appertains to make and use the same.

The invention relates to air control registers for fuel burners, and has for its object to provide a scientifically proportionedscroll casing Surrounding an air control register that will convert the pressure difference existing between the furnace and the draft pressure into the highest velocity so that the -maximum quantity of air can enter the register uniformly with equal distribution.

A further object is to provide a register casing that will deliver air uniformly to.

the register with less drop in draft pressure,

and greater wdischarging capacity.

A further object is to provide a casing to fitv on any standard air control register and provide an inlet duct that may point in any direction. i

The foregoing and other features of my invention will now be described in connecmore particularl tures which I be ieve to be new and of my own invention.

tion with the accompanying drawing forming part of this specification, in which I have represented my air register in its preferred form, after which I shall point out in the claims those fea- In the drawings'fa Figure 1 is a diagrammatic sectional view of my register and easing.

Figure 2 is a front view thereof.

In the carrying out of my invention the refractory wall 1 of anyosuitable furnace is provided with an opening 2, standard air re 'ster 3, atomizer 4. The register 3 is provi ed with means 5 shown as shutters or doors, to regulate the air entering the furnace, all of which is common to fuel burners 51d requires no further detailed description herein.

Surrounding the air register 3 I provide a casing 6 shaped like a volute scroll not unlike the oasing used in hydraulic turbines of the volute type and provided with a tangential inlet 7. .This is mounted to a plate 8in the furance front and adapted to V .be rotated about the axis of the burner and To effect this, the

held in any position. plate 8 may have a flange 8' provided with a grooved edge, in which groove the edge of the casing 6 fits. The friction between the two parts is normally sufiicient to hold th casing in any adjusted position.

By referring specifically to Figure 2 it will be readily understood that as the air enters the inlet 7 the shape of the volute air] passage changes the draft pressure into increasing velocity, thereby equalizing the amount of air entering the airregister between the regulating means 5.

The volute chamber 6 gradually contracts as the air moves into the register which maintains the velocity of air.

I wish it distinctly undersood that my apparatus herein described and illustrated is in the form inwhich I desire to construct it and that changes or variations may be made as may be convenient or desirable without departing from the salient features of myinvention andI therefore intend the following claims to cover such modifications as naturally fall within the lines of invention.

I claim:

1. An air; register, a casing surrounding the same and provided with a tangential air inlet and means for mounting said casing to permit the air inlet to be pointed in any directionin one plane 2. air register, a casing surrounding the same and provided with a tangential air inlet, and a mounting for said casing which permits its rotation to point the air inlet in any direction' in the plane of rotation.

3. An air register, a casing surrounding the same and provided with an air inlet, the

space between the casing and the register being in the form of a single volute scroll 5. An air register fitting in an opening in a furnace front and adapted to regulate the amount of air passing to the furnace and a casingsurrounding-the register'and provided with an air inlet, the air "passage between the casing and register having the form of a single volute scroll.

6. An air registena casing surrounding the same and provided with an air inlet, the space between the casin and the register decreasin as the distance roin the inlet increases, and means for mounting the casing to permit the air inlet to be pointed in varying directions.-- g An air register, a casing surrounding the same and provided with a tangential air inlet, the space between the casing and the register being in the form of a volute scroll, and means for mounting the casing to permit it to be moved to point the air inlet in all directions in one plane.

8. An air register, a casing surrounding the same and having a tangential air inlet, means for regulating the amount of air passing through the register, the passage between thecasing and the register being in "9. An air register fitting in an opening in a furnace front, and a casing surrounding the-air register and provided with, a single tangential inlet, said casing being formed to deliver air tangentially in substantially uniform amounts to all portions of the air re 'ster. Y

' testimony whereof I afix my signature in the presence of two witnesses,

- HARRISON E. KLEFFEL.
