. To all whom it may concern:

Be it known that I, HARRY E. Rosie, a citizen of the United States, and a resident of Spokane, in the county of Spokane and State of Washington, have invented a certain new and useful Improvement in Propelling Devices, of which the following is a specification.

My invention relates to lIIIPIOXGmGIIlJS in propelling devices, more particularly to propelllng devices for aeroplanes, and it consists in the combinations, constructions, and arrangements herein described and claimed.

An object ofmy invention is to provide a propelling device in which a plurality of movable blades or Wings is so mounted that, when the blades move toward the rear of the device, a greater surface area ispresented than when they move toward the front, thereby propelling the deviceforwardly.

A further object of my invention is to provide a device of the type described in which the blades or wings are mounted on said blades passing through the interior of a. casing in substantially folded condition and spreading out on emerging from the casing so as to present a greater surface area.

A further object of my invention is to provide a propeller of the type described 7 which may be used for other devices, such as boats. u

Other objects and advantages will appear,

in the followin specification, and the novel features of the 1nvention will be particularly pointed out in the appended claims.

My invention is illustrated in the accompanying drawings forming part of this application, and in which Figure'l is a perspective view of an aeroplane provided wit my improved propelling device. v

Fig.- 2 is a longitudinal sectional view through the device.

Fig. 3 is a transverse section along the line 33 of Fig. 2.

Fig. 4 is. an enlarged sectional view through one of the wings or vanes.

Fig. 5 is a perspective view of a modified form of link for the endless chain.

Fig.6 is a section along the line 66 of Fig. 4;

Referring now-particularly to Figs. 1 and 2, have shown therein a main frame 1 which supports one of the sustaining planes 2. This frame carries at its bottom the car 3 or basket, the engine 4, and has arearwardly extending portion 5 beneath which is disposed the lower of the main sustaining planes 6. The usual rudder 7 is attached at the rear of the device. The machine is cle signed to be supplied with ailerons and elevating planes, not shown.

The frame 1 supports a casing which I have denoted in general by C. As will be seen from the drawings, this casing consists of an inner cylinder 8 and an outer wall 9 which is tapered but which is cylindrical in cross section. These inner and outer walls are held in spaced relation by means of radially extending partitions or brace members 10, see Fig. 3. At the ends of the device between the brace members are disposed sprocket wheels 11. It will benoted that these sprocket wheels 11 are at the larger end of the device. At the other end are similar sprocket Wheels 12. These sprocket wheels bear endless chains 13, dike that shown in Fig. 2, or of any suitable form, as, for instance, having links like that shown in Fig. 5 at 14.

Secured to each of these endless chains is a series of wings or vanes, like that shown at 15 in Fig. 4. These wings are provided with suitable brace members 16, in. order to withstand the Wind pressure. Fig. 1 shows the preferred arrangement of these wings. From this .figure it will be seen that the wings of adjacent sets are not disposed in the same plane but are slightly offset, being arranged like the ribs of a fan, one slightly behind the other, so that when they are brought into folded position they will lie one behind the other. In the drawings I have shown only a few sets of wings, but

obviously a greater or less number may be the sprocket wheels 11, the axle of one Wheel outside, said vanes being connected to the aXle of its adjacent wheel by means of a universal joint 20.

Now it will be obvious that, as the endless chains travel around the sprockets 11 and 12, the vanes or wings 15 will be carried with them. These vanes or wings are arranged so that they will enter the large end of the casing C and diverge from the small end. Owing to the shape of the casing the wings will be virtually in alinement, that is to say, behind one another, just as the ribs of a fan are behind one. anothenwhen the fan is closed. The effective surface area of the line of wings which are advancing toward the small end of the casing, is, therefore, not much greater than that of one of the wings, while on emerging from the small end of the casing, the wings spread out into the form shown in Fig. 1, whereby the full surface area is available for .propellingthe device.

In order to reduce the back pressure due tothe forward movement of the device, I provide a conical shield 21 which is carried by the frame 1, and which is spaced from. the casing C just far enough to permitthe. exit of the wings or vanes,

The same principle might be applied to the propelling of boats or other water craft.

I claim 4 1, In a propelling device a hollow cylinder, a series of wings or vanes movably mounted on said cylinder and arranged to travel from one end of the cylinder to the other on the inside-thereof and back on the being one behind the other when on the inside of the cylinder, and being spread out when on the outside of the cylinder.

2. A propelling device comprising a 1101- low cylinder, a series'of endless chains carried by the cylinder, means for driving said chains, and a series of wings or vanes projecting laterally from the chains, said wings being carried by the chains out of one end of the cylinder and into the other end of the cylinder by the movement of. the endless chains- 3. A propelling device comprising a hollow cylinder,.a series of endless chains eX- tending longitudinally of the cylinder, each of said endless chains havlng .a portion inportion outside the side the cylinder and a cylinder and portions encircling the end of the cylinder, a series of wingsor vanes carried by each endless chain, causing the travel of the chains.

4. A propelling device for aeroplanes comprising a hollow cylinder, .a series of endless chains disposed longitudinally of the cylinder, a portion of each chainbeing on the inside of the cylinder and a portion on the outside, a series of wings or vanes carried by eachendless chain, the wings of one chain being slightly out of alinement with and means for menace 5. Ina propelling device I01 aeroplanes,

a'cylinder, a plurality of endless chains carried by the cylinder, said endless chains being disposed longitudinally with respect to the cylinder and having portions on the inside and outside of the cylinder, a series of wings or. vanes carried by each of said longitudinally extending chains, the wings of one chain being out of alinement with the wings of the adjacent chains on either side thereof, and means forxca'using the movement of the chains-I from one end of the cylinder to the other at a uniform speed for allthe chains.

6. In a propelling device for aeroplanes, a casing having a double wall, one of said walls being an inner cylindrical wall and the other wall being an outer tapered wall of cylindrical cross section, an endless chain disposed longitudinally of the casing and arranged to travelthrough the inner portion of the casing in one direction and in the opposite direction on the outside of the casing, a plurality of wings or vanes carried by said endless chain, endless chains disposed in'parallel arrange ment with said first named endless chain around the casing, each of said endless a plurality of similar a casing having double walls, the inner wall being cylindrical, the outer wall surrounding the inner wall and being tapered, said outer wall being cylindrical in cross'section, a plurality of endless chains disposed longit' portion of each chain being on the interior of the casing unda portion being on the exterior, means simultaneously so as to travel toward the for moving the said chains udinally with respect to the casing, a

larger end ofthe outer wall on the exterior thereof, and in the opposite direction within the cylindrical interior wall, a plurality of wings or vanes carried by each of the endless chains, said wings or vanes being arranged in groups with the'wings of adjacent endless chains, the wings of any one group being arranged to move one behind the other when the wings are on the-inside of the casing.

8. In a propelling device for aeroplanes, a casing having double'walls, the inner w all being cylindrical. the outer wall surrounding the inner wall and being tapered, said outer wall being cylindrical in cross section, a plurality of endless chains disposed longitudinally with respect to the casing, a portion of each chain being on the interior of mew the casing and a portion being on the exterior, means for moving said chains simultaneously so as to travel toward the larger end of the outer wall on the exterior thereof and in the opposite direction within the cylindrical interim Wall, a plurality of wings or vanes envied by each of the endless chains. wings or vanes being arranged in groups with the wings of adjacent endlesschains. the wings of any one group 10 spaced therefronito permit theexit of the 5 vanes or wings.
