2 Claims. (c1.1'70 f-f1 e 1 a This invention appertains' tonevv and useful improvements inf-propellers of the screwtype'yi The principal ,object of the present invention.
isto provide a propeller of the screw type having spirally disposed blades mounted on a revolving shell and which can be employed for use on either air or marine vessels.
Another important object of the invention is tov provide a propeller of the spiral blade type, constructed in such manner as to promote smoothness in operation and relief of a considerable amount of the strain which normally exists on the drive shaft and propeller blades of conventional type propulsion mechanisms.
Another important object of the inventiori is to rovide a propeller constructed in such a manner as to permit ready demountability for the purpose of repair or replacement of parts.
These and various other important objects and advantages of the invention will become apparent to the reader of the following spe'ciflca- Figure 3 represents a side elevational view of the shell.
Figure 4 represents a front elevational view of the nose cap.
Figure 5 represents .a fragmentary longitudinal sectional view through the drive and driven shafts mounting. e
Figure. 6 represents an enlarged vertical sectional view taken substantially on the line 65 of Figure 5. I
Figure 7 represents an enlarged fragmentary detailed sectional view taken substantiallyon line 1--1 of Figure 5.
Figure 8 represents an enlarged fragmentary: detailed sectional view transversely through the propeller blade and supporting shell. e
Referring to the drawings wherein like numerals designate like parts, it will be seen in Figure 1 that 5 represents thefuselage of an aircraft of the monoplane type having a forwardly re- (see Figure 5) extends. This tube 1 is fixed axially within the nose 6 by struts 8, each end of the tube 1 being provided with a removable adjacent portion of the v header 9qbetween which and the adjacent roller; bearing mount ID .a; packing, element Ill is; placeds: y
7; The. drive shaft that connected by theluni-j versalij'ointj 2 ,to the;usua1"orankshaft;;of the engine (not shown) is denoted by the numeral I3 and extends throughthe rear header 9 into the tube 1 to terminate withinthe hollow head M of the driven shaft [5.
The last-mentioned end of the drive shaft 13 has a reduced portion 5 extending into the pocket I! where it is supported by the roller bearing mount l8, Adjacent the roller bearings 18 are the roller members I 9 which are interposed between the drive shaft'l3 and the inner side of the enlargement I4 as clearly shown in Figure 'l. A ring 20 isthreaded over apportion ofthe enlarged end M of the driven shaft l5 and is flanged as at 2| circumferentially to hold'the packing 22 in place and preventdisplacement of the aforementioned roller members l9. -As canbe clearly seen in Figure 6, these roller members l9 ride against the periphery of the drive shaft l3 and are'carried'by the cam-shaped pocket 23 at the inner side of the head [4 of the driven shaft [5. In this manner afree [wheeling clutch is afforded which will permit.
the propeller to rotate independently engineand drive shaft [3.
The drive shaft l3 has a thrust collar 24 for engaging the rear roller mount I I3 while the for- Of the ward end portion 'of the driven shaft l5'is pro-' vided with a reduced extension 25 defining a:
driven shaft IS. The shell 29 is provided with spirally-disposed slot-ways 3|, leaving spirally 45, 'f gitudinal edge and an inturned flange G' at its I cap 34 is provided with spirally disposed flanges 36 to. which the forward end'extensions of the blade 32 canbe secured. The cap 34 is provided with a hub S'Iwhich isprovided with a key slot 2 '38 at its inner side which can be meshed with a wardly tapering shell, a conical-shaped cap for key slot on the reduced portion 25 of the driven shaft and keyed to positively connect the driven shaft l5 withthe cap 34, to the end that the cap 34 will rotate the shell 29 which carries the propeller blade 32; 7; Z
Obviously, a" propeller constructed in accordance with the foregoing specification will be more desirable than the elongated outstanding screw siderable vibration to'the craft. ;This;vibrati on is scarcely noticeable in a "craft equipped with the propulsion means herein described.
' Obviously, when two of these propellers 'are' employed in juxtaposition, they are constructed -with the blades disposed in, opposite spiral direction, so that any te'ndencyiof the-craft as regards deviation will be neutralized. r
While the foregoing specification sets forth the I invention'in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from thespirit and scope of the invention as claimed hereinafter.
Whatisclaimed is:-- o
1 A propeller comprising an elongated forthe flanges "on the shell, said-blades'b eing extended forwardly and connected to the flanges on the can.
type propeller which in operation imparts con-, -I f 2. Alpropeller comprising an elongated forwardly tapering shell, a conical-shaped cap for the reduced end of the shell, drive means connected to the cap, spirally disposed flanges-onthe s'helLflan'ges on the said cap aligned with the spiral flanges on the shell,"and blades secured to STEVE KISS; 25
