Be-it known that we, ANDREW J. NnLsoN and M1 NELSON; citizens of the Uniteclfitates, residing at St. Paul,' in the county oft Raniseyand Stateof lrlinnesota r have invented certain new and useful-Improvements in .Boatlropelhng Dev1ces,'0f which the following is a specification (Eur invention relates to propelling '0 mechanismsfor-boatsandvessels. Thejob V ject is" to provide power driven boats with Va propelling device that obviates the tendency or" earlier prope-ln g (lG'VlCGS,"l1l-i propellers and paddle wheels, to get en i tangled in weeds 'an'd. elsotoweste nnch power: by pressing downward and upward 1 in the water whichot'course doesnot serve to propel the boat as can readily be understood by looltingat a paddle wheel how, it presses deep' cavities in the water before pulling forward at all, and at ing' must be forced to the surface and raise quantities of water above the surface. As for a regular propeller itisobvious that "it ;*astes inuch power in being rotated and only a portion o'l the power is, by' the incline oi the wings, converted into actual propulsion of the boat.
In the accompanying drawing t Fig. l is a' plan or top view of e power driven boat equipped with our new proe pelling device.
F 2 is an enlarged side elevation of the rear portion of the boat in Fig. l. Fig, 3 is an enlarged top view ot-one of the water devices ot' theappa re'tus. t s r V Fig. 4: a left end view of Fig. 3.
Fig. is a side view of 4o Fig. 6 anedge view of one of the sddles modified. 7 r V Referring to the drawing by rel'erencentt lnerals "T designates a boat orvessel tobe b progelled by motive power which may he or" as any suitablekind but weha-ve illustrated the same by two steam cylinders 8 receiving steam through piping 9 from asteani boiler (not shown). LO-indicates a bed-plete secured at llvupon the boat and having rear-V .vardly directed arms l2,rthe rear end of;
which have journal boxes 13 for a multiple rank shaft 14:, the ends otwhioh are cash provided with crank 15 ,drivenby' acon nectingrod lti' and a, piston rod l Tfin-one of the cylinders 9, the latter being also prefe ablysecured upon llllefiitffle, bedfplates 1O ter some pull-b 'QLSGN, or srrnnn rzrnnnsorn.

c.1922. Serial Ne sparse;
their own. r l g l y t t r I Secured upon thefbed plate 1O are a series I or bearings 18 in wl o'ds' ll) each of which has secured-to its t rear end by a joint 2O a 'barQl having 21 journal box 22 engaged by oneof the cranks v 23 of the shaft 1*. o t m Each bar2l has itsrear end provided witlra paddle plateQd fixed atebout right angles to theibar and preferably curved in 4 horizontal direction and having its upper corners sloping as at 25 in Fig.4to prevent their; catching and; liftingof sea weed or other obstructions in thfe :water. ilWhenJthese paddles are large they may have braces about as 26 in Figs. 3 and send maybe secured tothe paddle bars 21 by transverse angle irons 2? or inany other suitablefnianner. The bars21 may also be 7 off any suitable inaterial and formin cross 7 section, but ordinarily itis believed that I- beains will be preferable and we have there-s fore "indicated them as such in the drawing.
In the operation, when the boat is to travel forward, the crank shaft 18 rotated in the direction of the arrow 28'1nF1g. 2,
whereby the paddlesare in successive als ternete order plunged .edgewise down lnto 5 j in the water when working backward as when pushingrorward5]but they get hold enough torthe purposein question; V
In special cases it it be desired to have the propelling device at the front end of the boat, so, as to break up thin icein front of the moving boatythe paddles are reversedwith the concaveside toward-the boat and their lower edges arechise'l shaped as shown 'st 24* in Fig. 6. a In the latter View it is tiple'jcranlr shaftjjournaled across oneend 11 it of the host,- a series of normally vertically disposed;paddles, a seriesof' paddle bars" I h slide, several parallel 60 also indicated that the paddles maybe fiat each w th one end fixed to one of the paddles and llilVlllQ its bodv journaled to one of the (cranks or" the shaft, a series of rods inded to slide horizontally and hating; each. one end pivotally connected to one of the paddle bars, and means for rotating the crank shaft. v V
' L. The structure specified in claim 1, in
which the paddles are arched in horizontal direction tOfOlID a concave surface on the Si(lQ n11lZ1iy used "for propulsion.
3. The struct re-specified in claim 1, said paddles having their corners slanted so as not to'catch and lift seaweed or like matter.
steainengine having two cylinders each with a piston rod and pitman connecting it with one of the said end cranks.
In testimony whereof We our signatures.
