Serial No. 447,951.

known as aero-mobiles or helico sters in` which rotary horizontal blades are employed, arranged at such an angle that they exert a lifting action upon the machine.

The principal object of theinvention is to provide an improved blade or propeller structure, which is so shaped and braced as not only to preventbreakage or distortion when subjected to abnormal strain, but to hold each blade at all times in proper relative position to the other, and in proper relation to every other part of its own surface.

With the foregoing and other objects in view, the invention consists in the novel construction and arrangements hereinafter described and referred to in the appended claims. i

The invention is illustrated in the accompanying drawings, in which,-

Figure 1 is a side elevation of an aeromobile propeller, constructed in accordance with my invention. Fig. 2 is a trans-verse sectional view ofthe same on `line 2-2 of Fig. 1, the vertical shaft and cross arms being shown in elevation; Fig. 3 is a detail perspective view of a portion of the blade structure, showing the arrangement of one of the braces; Fig. 4 is a detail section through one of the brace-connecting arms; and Fig. 5 is a detail perspective view, showing one of the brace connections with the blade.

The base or main frame of the apparatus, as shown in the drawing, is merely typical. It comprises a. pair of triangular end frames a, connected by tubes 7). The tubes which constitute the flooring and upper structure, are provided with bearings for the reception of a pair of vertically disposed parallel shafts o and Z, which are connected by gearing d. On the sha-ft o is a motor, which may be driven by any suitable power, but is preferably a hydrocarbon motor. This motor as shown conventionally in Fig. 1 mounted'on the shaft c, is rotatable about a vertical axis and carries a small pinion meshing with the gear d.

The vertical shaft 1 carries a sleeve or collar 2, secured in place by a key or the like. From this sleeve extend diametrically opposite socket members 2, in which are seated blade-carrying arms 4, which are preferably of rectangular form in `cross section and gradually taper from their inner to their outer ends. 4 i

On the arms are secured fan blades 5, which preferably are formed of sheet metal, said blades being inclined in opposite directions respectively, `and their active faces being slightly concaved by tension wires 6, which extend vacross the blade surfaces near the outer ends'thereof.

The thin metallicblades have reinforcing strips 7 extending along each edge of their rear surfaces, and extending from side to side of 'the face of each blade are cross strips 8, these being bowed across the arms 4, and being permanently secured to the arms and blades 5 by suitable-rivets, as shown at 9.

' Arranged between the cross strips 8 and the blade, are spacing blocks 10 which are located about midway between the arm 4 and the edges of the blade and secured by bolts or rivets 11.

Secured to the vertical shaft are upper and lower arms 12 and 13, disposed parallel with each other and at right angles to the arms 4. These arms 12 and 13 are in the form of T bars in cross section, and are arranged to hold the ends of a number of brace rods or wires that extend from the fan blades.

The primary brace rod 14 of the blades is in the form of a tension wire that passes through an opening 15 formed in the shaft 1. The ends of this wire pass to the ends of the arm 4 and extend through openings formed in small cross bars 16 that are secured to the extreme outer ends of the arms 4 and pass through openings in the blades (see Fig. 3). The ends of the rod are threaded and receive clamping nuts 17, by which it is properly tensioned and held in place. To the lower ends of the cross bars 16 are secured the outer ends of brace rods 18, that pass to the lower arm 13 and eX- tend through openings 19- forrned in said bar. These rods 18 incline forward in the direction of rotative movement of the blade to which they are attached `and greatly strengthen the blade.

of auxiliary bracing rods is also employed. rl'hese extend from the arrns 12, 13 to the blades, and at the latter pointiare :connected in the manner best shown in Fig. 5.

rlghrough the edge battens 7, the .blades 5,2 and cross strips .8, are drilled vholes for the; Vreception off pins 2d, These vpir-1s project `jbeyond the opposite faces `of the blades, and?y yhave lopenings ,for the passage of the braces, the latter being threaded and theld .in placey by .nuts '25. l

Probably the greatest .stra-in .fon each blade These brace's Vpass through openings 28 formed in .both the upper and :lower arinsl 1213` at the saine side as the forward edge of the blade, and are held in 4place by nuts- 29.` The Jbraces run vin pairs from the upper and vvlower Afaces ofthe blade, their tension .may nbe readily adjusted ,by `turning :the `nutslf? and 29. In addition yto these, four Iauxiliary `braces arranged .in .pairs (eee 30e-31) run from the rear :and `lower edges of the blades Ato `the yarn'ls 12 and 13, andi are confined by nuts 32.

a These serve to i Atraiisinit the strain vJQQBOL bllrd@ et@ iblad, and

make :the whole fabric :taut and .properly braced and 'tensioned for moving at lhigh speed. Lt will be seen that by arranging the moving .-partsof the motor -to rotate horizontally, thatsaid l motor will ac t as a gyroseope to steady .the vessel while the same is in motion.
