ELLIOTT E. FURNEY, 0F SCI. LOUIS, MISSOURI, ASSIGNOIR OF ONE-HALF TO JOHN F. ONEIL, OF ST. LOUIS, MISSOURI.

PROPELLER.

Specification of Letters Patent. Patented June 21, 1910,.

Application filed October 18, 1909. Serial No.- 523,273.

To all whom it may concern:

Be it known that I, ELLIOTT E. FURNEY, a citizen of the United States of America, residing in the city of St. Louis and State of Missouri, have invented certain new and useful Improvements in Propellers, of which the following is a full, clear, and exact description, reference being had to the accompanying drawing, forming part of this specification.

My invention relates to a propeller more particularly intended for use in airships, or which may be used upon other craft, such, for instance, as marine vessels. Inasmuch, however, as the propeller is especially adaptable for use in airships, it will be herc in Considered as utilized upon a vehicle of this nature.v

The object of my invention is'to produce a propeller in the use of which. a partial vacuum may be created in fiont of the. propeller due to the production of centrifugal force within the propeller, thereby reduc ing atmospheric resistance in front of the propeller; and, further to provide moans within the propeller housing against which the fluid is delivered tangentially to be de fiected therefrom in a backward direction,

and in the striking of which thetluid acts to create force in. a forward direction by v virtue of which the propeller is advanced into the partial vacuum constantly main I tained in front of the propeller.

Figure I is a front elevation of my propeller with the propeller frame in section on line" I-I, Fig. II. Fig. II is a view of the propeller partly in side elevation and partly in section,

In the accompanying drawings: 1 designates the housingof my propeller which is open from end to end, and is-preferably of cylindrical shape. This housing is supported by a: frame 2, preferably of rectumgular shape, as shown-in Fig. II, and which may be connected in any suitable manner to I I mounted in e journalfboxes '3, and which may be driven by' any "suitable motor lo-' cated back of the -5 designates the hub of the propeller ing at an angle to the plane of the body ofthe wing, and which is adapted to cause each. wing to catch the air more efficiently during the rotation, of the propeller wheel.

disk 8 that serves to prevent the passage of air through the propeller whecl throughout the radius of said disk, and which, by its presence, makes it necessary that the air acted upon by the propeller wheel within the housing -1 be thrown outwardly with centrifugal force to strike, tai'igentially, vanes to be next particularly mentioned.

9 designates a plurality of turbinate vanes arranged obliquely iu the housing 1, relative to the axis-of the propeller, which are preferably of less width at the forward end of the propeller than they are atthe rear end "of the propeller.

in back of the disk 8 at the rear of the pro peller wheel, while atmospheric airpressure exerts a forward pressure against the disk, thereby affording additional propelling force,-under the influence of which-the propeller is driven intothepartial vacuum constantly created in front of thepropeller.

It is to be'n'oted that the disk 8 in m'y propelleris capable ofafi'ording shelter for the motor by which the propeller-shaft l is op' erated, and which isintended to be attached directly to the propeller shaft, in order that the'motor may not offer resistance even during themost rapid flight of an airship At'the rear of the propeller wheel is a During the rotation of the propeller or 'What may properly be termed deflecting vanes, counteracts the tendency of the motor to rotate an airship, equipped with 111 propeller, in a; direction the reverse of t. at in which the propeller is being operated. The construction, therefore, permits the use of a. single propeller instead of two propellers that are designed to balance each other with the object in View of preventing the rotation referred to.

' I claim:

1. In a ropeller, e, l'iousing, vanes at the interior 0? said housing, and. a propeller Wheel operable to produce centrifugal force in. said. housing and by which fluid is'delivcred ton entially therefrol'n to the rear sides of sai vanes, the said propeller Wheel havinlg o disk back-of its wi' gs.

e propeller, a. housing turbinetevanes within said housing, and a propeller operable to produce centrifugal force in said housing to deliver fluid tangentially there: from to the rear sides of said turbinate vanes, the pro eller wheel having a disk located back 0'v its Wings.

3. In a propeller, a housing, turbinate tober 1909.
