To all whom it may concern:

zen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a, certain new and useful Improvement in Propelling Engines or Motors, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawforming a part of this specication.

ny' invention relates to boat propelling equipment and finds its preferred embodiment in connect-ion with motors that are in the form of hydro-carbon engines, though the features thereofma be embodied in ass o ciation. with other orins of motors as will beapparent from the description to be given.

One `feature of my invention resi es in the provision of improved means whereb a motorV driven propeller may be bo ily shiftedthrough an an le of 180 to reverse the direction' of trave of the boat without reversing the4 direction of rotation of che propeller. The means for shifting the propeller is preferably so constructed that the propeller may be bodily swun to the right or to the left through en4 ang e of 180 in each swinging movement. Where it is desired merel to swerve the boat, the extent towhich t e propeller is bodily swung is suited: tothe degree to which the boat is to be swerved. In practising this feature of m invention a pinion is in fixed relation with the bearing for the` propeller and a handle operated segmental gear is in mesh with the pinion, the areal reach of the gear being of such extent that the pinion may be turned a half revolution in either direction for the purpose specified, the radius ofthe segmental gear being'suiiiciently'large so that the swinging of the handle, where grasped, is suiicientlyl small to make the `operation of the andle convenient. The segmental gear and pinion in mesh therewith constitute one form of mechanism for increasing the angular motion of the propeller in its bodily movement with respect' to the angular ino-y tion of the handle so as conveniently to reduce the swing of the handle as compared with the bodily swing: of the propeller.

I am aware that it is old bodily to swing motor driven propellers throughthe agency iof pinions and segmental gears and also Be it known that I, J Amis H. Ponen, citithrough the agency of two meshing segmental gears butthe constructions of the yprior art havin these characteristics were i of such nature t at the bodily movement efi fected for the propellers was limited so that lit' was possible only to swerve theboat in lits forward movement whereas with the equipment of my invention the boat may not only be swerved in its forward movement but may also be caused to move backwardly and swerved in its backward movement.

My invention has other features and will 5 be fully explainedl by reference to the accompanying drawings .showing the preferred i embodiment thereof and in which drawing- Figure 1 is a sectional elevation of an engine or motor driven propeller mechanism lequipped in accordance with the invention; Fig. 2 is a rear view of the structure shown in Fig. 1, a tubing portion being broken away to reveal some characteristics of construction; Fig. 3 is a plan view of the mechanism illustrated in Figs. 1 and 2; Fig. 4 is a sectional view on line 4 4 of Fig. 1; and Fig. 5 is a sectional view on line 5 5 of Fig. 1.

Like parts are indicated by similar characters of reference throughout the different figures.

The motor which I preferably employ is in the form of a hydro-carbon engine of any suitable internal construction. The engine is equipped with the usual cylinder 1, reciprocating piston 2 Working within the cylinder, a pitman 3 connecting the piston with the crank pin of the crank 4 upon the propeller shaft 5. The ily wheel 6 is fixed upon the upper end of the shaft 5 and a suitable fuel reservoir 7 intervenes between the iy wheel and the engine casing. The engine casing is provided with a downwardly extending sleeve 8 which is preferably formed in the saine integral casting with the portion of the engine casing with which the sleeve is directly connected. A similar but upwardly extending sleeve 9 is provided at the upper portion of the engine casin the sleeves 8 and 9 being co-axial and alining the portions of the shaft 5 that are upon opposite sides of the crank 4, these sleeves thus constituting bearings. The use of inserted bearing metal within the sleeves 8 and 9 is preferably avoided by forming these sleeves and the portions of the engine casing inte al therewith of bearing metal. The prope ler 10 has its hub portion fixed with respect to a shaft 11 and this shaft is provided with bearings at its ends in a gear housing 12. A miter gear 13 is fixed with respect to the shaft 11, and a miter gear 14 that is in mesh with the miter gear 13 is in fixed relation with a shaft 15 that is co-axial with and is driven by the shaft 5. 'the driving connection between the shafts 15 and 5 includes a sleeve 16' surrounding the lower reduced end of the shaft 5 and connected therewith by a pin 17. The sleeve 16 is provided with a s line 18 engagin a splined slot in the s aft 15. The sp ine 18 is preferably wedge-shaped in cross section and the sphned slot receiving the same is correspondingly shaped, this construction being superiorto one in which the spline and splined slot are rectangular in that lost motion between the parts is taken up. The sleeve 8 is downwardly elongated and has apertures 19 (Figs. 1 and 2) to permit of the insertion of the pin 17.

By the construction thus far described the shaft sections 5 and 15 are relativelyadjustable longitudinally of their common axis in order properly vertically to position the propeller with respect to the boat. In order that this adjustment may be determined and may be secured when determined I preferably provide a sleeve 20 which is in telescoping relation with and receives the lower end of the bearing sleeve 8, another sleeve 21 receiving the upper end of the sleeve 20 and having a slot 22 at its lower end to constitute the lower ortion of the sleeve 21 a clamping member, t is portion of the sleeve 2l being contractible by means of a clampin wing nut 23 engaging lugs upon opposite s1des of the slot 22. When the bolt 23 is tightened the sleeves 20 and 21 are brought in fixed relation whereby the propeller is held properly vertically spaced from the engine. The sleeve 21 engages a lower or step sleeve bearing 24 fixed by means of a suitable mounting, whose referred form will later be described, witi respect to the stern 25 of the boat. The support 24 holds the sleeve 21 and owing to the clamping engagement between the sleeves 2l and 20 effected at 23 the shaft sections 15 and 8 are held in the relative positions that are determined by the longitudinal movement of the shaft 15 within the sleeve 16, the lower end of the shaft 15 being in fixed relation with the hub of the spur ear 14. The shaft 15 is prevented from dropping owing to the engagement of the spur gear 14 with the spur gear 13 and the fact that the bearing for the spur gear 13 is in fixed relation with respect to the sleeve 20, this bearing being an inwardly extending projection of the housing 12 that is fixed with res ect to the shaft 20. The housing 12 may ave an upwardly extending projection 26 which may constitute a bearing sleeve for the lower end of the shaft 15 and which may or may not have its bore faced with special bearing metal as desired. The step bearing sleeve 24 desirably carries radiall projecting bolts 27 which extend throug areal slots 28 in bracket arms 29 that project from a bracket frame 30 clamped to the stern or other suitable portion of .the boat by means of clamping wing nuts 31. The engine casing has swinging connection at 32 with the bracket frame 30 and the slots 28 are upon circles whose centers are located at the mounting shaft 32. By this constructionfthe propeller 10 and the engine drivin the same may together be swung bodily 1n a vertical plane to determine lthe proximity of the pro eller, whose vertical position has been adjusted, with respect to the boat. After this adjustment has been determined it is secured by means of wing clamping nuts 33.

I will now describe the feature of my invention that enables me to swing the propeller as desired and suiciently to reverse the travel of the boat, and while this feature of my invention is preferably practised in connection with the construction above specifically described, the present feature of my invention is not to be limited to association with the foregoing construction.

The upper end of the sleeve 21 turns upon the upper portion of the bearing sleeve 8 and is there provided with a pinion 34 fixed with respect thereto. This pinion 34 is in mesh with a segmental gear 35, the center of which is coincident with the mounting for the segmental gear 35 located at 36, this mounting pivotally supporting the segmental gear upon and beneath the casing of the engine. The arcal reach of the pitch curve of the segmental gear is so proportioned with respect to the pitch circle of the inion that the segmental gear, when swung rom its middle position in either direction, is adapted to turn the pinion through an angle of 180. The segmental gear 35 is provided with a handle 37 the mounting 36 being interposed between the segmental gear and the handle. The radius of the segmental gear and the radius of the pinion are so selected that a given angular movement of the handle 37 will be accompanied by a materially increased angular movement of the pinion 34 and a bodily movement of the propeller 10 similar to the movement of the pimon 34 whereby the range of operation lof the handle may be confined to the space between the sides of the boat for the purpose of turning the pinion throughout its maximum movement of 180 in either direction. The pinion 34 being fixed with respect 'same will be accompanied by a corresponding bodily movement of the propeller 10 so that the direction of the boat may be swerved when the pinion is turned through angles less than 180 and may be completely reversed when the pinion 1s turned completelyI through an angle of 180, and after having been reversed the boat may be swerved in its backward movement but in one general direction consequent upon the turn of the pinion 34 in one direction 180 by suitably swinging the handle. In Fig. 1 a completely reversed position of the propeller is indicated by dotted lines. By mounting the handle at 36 upon the engine or motor casing the handle and segmental gear 35 keep their relative positions with respect to the-engine casing as the said casing is adjusted about the bolt at 32 so that t e gear 35 and the pinion 34 are Vmaintained properly in mesh. The tube or sleeve that is turned by the operation of the handle for the urpose of turning the propeller shaft housing is contracted at its upper end so as to have limited engagement with the sleeve that constitutes a downward extension of the motor casing so as to improve the operation of the steering and reversing mechanism.

The handle 37 is desirably formed in two sections as illustrated most clearly in Fig. 1, one section being integrally formed with the segmental ear 35 while the other section includes an o set portion 38 that is insertible through an aperture in the companion portion of the handle, this companion por- `tion of the handle thus being interposed between the offset portion 38 and the shank of the handle which extends to the grip 39. The grip section of the handle carries a bolt 40 upon which a wing nut 41 turns, the elements 40 and 41 serving to maintain the two sections of the handle together when these sections are assembled.

While I have herein shown and particularly described the preferred embodiment of my invention I do not wish to be limited to the precise details of construction shown as changes may readily be made without departing from the spirit of the invention, but
