AERIAL rRorELLER,

To-all whom it maywe'nccmr 'Be'it known that I, THOMAS Fanny, a

nected up w h theai-r-craft that it will be capable-of a yustment at any point from the horizontal to the perpendicular, 'orto a position any where w1th1n 90-degreesof a-circle.

In the drawings, Figure 1, isfan enlarged elevation of the propeller together with the Fig. '2, is a side elevation of two of the pro-.

mechanism operatingimmediately therewith,

pellers and the mechanism immediately connected therewith, together with arr'outline of an air craft frame Work, showingthe adaptability of the propellers -to thejart, and Fig. 3, is a plan viewof the propellers and the parts operating immediately therewith,

and an, outline ofan air craft illustrating the applicationof the propeller-to the art. It is proposed-that for practical purposes two of these propellers would be used upon a craft, one kztat the front thereof and one.

7256 near the rear thereof. We have shown the propellers' in a perpendicular sition but'by means of the construction an the -use of cables operating over sheaves and {manipulated by drums or other mechanism, the

'- same can be thrown forward to the'hofizontal as shown by the dotted lines k2? and lay;

Of course the propellers maybe thrown to any intermediate position. If it'isdesired -the, r'1oSfitionshown in the drawings, while that the graft shall be elevated perpendicularly' the propellers would befused'in might be'desirable to throw them in'f'the tionof the dotted lines as indicatedfia a forward and upward movement' iiffthe craft, some position intermediate; offlietwo' extremes would be chosen for. .the pi'opeller and future adjustment thereof be governs by the needs from time time as to whether 1 it. is desired to move upward, fforward" or;

both A specially constructed base A is provided for the wings b and b of the propeller, the base A. being-0f greater diameter "shaft' 'M extends through the Specification of Letters. Patent. Patented Jan, 10, 1911. Application am June 29, 1910. "Serial No. 569,519.

fidiameter at the inner ends, there being a gradual rtaper from one extreme tc'the other and are wrapped'about the base A. from the outer end thereofto a position near the hub L,each wing extending about half Way around-the base A.- Strengthening webs c extendfrom the dome 'bh'of the base A to points'on the wings-b and 7) near their diameter, while braees' e, f and g hold the wings b and b in position. The-propellers ha and by are adapted to rotate with the shaft m and base A. -lhe hxili-L ref-the base provided with a sheave-k imaeable, and sheaves t, a, 'v and "w are monntedropon the shafts. An endless cable as reaching from the source of power passes over the sheaves w, o, u and t thence around the sheave k, thence over the sheaves- 't, u, 'v' and w and back to the source of power,'by means of whichthe propellers Ice and lay are rotated. To the frame 01 are connected the standards means of the rods an to the lower ends ,of which standards are secured the sheaves To the frame va1 are also secured sheaves ab, ac, ad, ac and ab; To the bottom of the shafts m are secured the sheaves -2. To the frame al also are securedthe sheaves am. By means of the cable of operating over sheaves ab and 2 "the propeller k2 is tipped to theposition of the \dotted lines 102' or any intermediate position, the cable aLg serving as an assistant in holding the same steady and to a final restposition. B means of the cable 00 operatmg over the eaves ab and z the propeller ky-is ti ped to the position of the dotted lines kg or to any intermediate position, the cable ak operating over sheaves Y and Z and serving to steady the same and help hold'the same in final osition. The shaft sand the boxing n and is connected with the base A -r-so thatthe wingsib andb'the base A and shaft m rotate'together. The shaft m has a beefing in-theboxingmP. r Having thus descri d my invention what 3?]: claim asn'ew and useful and desire to seieure by Letters Patent 1. anaerial propeller, a base connected to, the end of a' shaft,"such base being frusto conical in form,the greatest diameter being then ear end, and the end',of largest diameat the far end and the smallest diameter at.

wings with their greatest diameter secured to the outer end of the base and their smallest diameter to the'inner end thereof, each.

wing encircling such base in diagonal form and practically half way around the same, strengthening webs extending from the dome of the base along the outer edges of the wings acrosstheir greatest diameter, braces supportingthewings in their positions, the

hub of the base provided with a sheave, and the shaft to which the base is secured adapted to rotate in a boxing secured to the frame work of the air craft, substantially as described.

2. In an aerial propeller, a base connected to the-end of a shaft, such base being frusto conical in form, the greatest diameter being at the far end and the smallest diameter at the near end, and the end of largest diameter being capped by a dome fixed thereto 'and such base being encircled by two taperin wings with their greatest diameter secure to the outer end of the base and their smallest diameter to the inner end thereof, each wing'encircling such base in diagonal form and practically half .Way around the same, strengthening Webs extending from the dome of the base along the outer edges of the wings across their greatest diameter, braces supporting the wings in their positions, the hub of the base provided with a sheave, a shaft transversely arranged con- 'nected at its center to a boxing and at its ends to the frame Work of an air craft, standards reaching from such transverse shaft and secured to the frame .work of an air craft, and'extending substantially vertically and perpendicular to the shaft to which the propeller base is secured, both such standards-and the last named shaft be-' ing provided with sheaves at their lower ends, sheaves secured to the outer ends of the transverse shafts, the sheaves adapted to receive cables connected with a moving mechanism radiating from a source of power, substantially as described.

In testimony whereof I afiix my signature, in presence of two witnesses.
