Iments for Boats, of which the followingis a specification. Y

My invention is an improvement in that class of propellers which are adapted to be detachably connected with boats and suspended in the water at the stern.

My invention includes novel and improved features, as hereinafter set forth and claimed, the same being illustrated in the accompanying drawings, in which- Figure 1 is a longitudinal section of my improved apparatus or propeller attachment arranged in the position for use, the outline of the stern of a boat being shown by dotted lines. Fig. 2 is a side view, inreduced proportions, showing the same apparatus in the folded position as when detached from the boat. Fig. 3 is a view illustrating details of construction by which the two hinged portions of the apparatus are rigidly secured to each other when the propeller is in working position. Fig. 4 is a plan view of the apparatus or attachment in working position.

Fig. 5 is a transverse section on the line 5 5 of Fig, 4. Fig. 6 is aperspective View of one of the adjustable bars by which the horizontal portion or platform of the apparatusv is secured upon the deck and stern of a boat. Fig. 7 is a perspective view, including the rear portion of the platform, adapted to be secured upon the stern of a boat, together with the driving-shaft and its bearing.` Fig. 8 is a perspective view of the rigid bracket or frame in which the 4propelling mechanism proper is arranged and supported. Fig. 9 is an renlarged horizontal section on the line 9 9 of Fig. 1. Fig. 10 is a vertical section of the rear steering-wheel, parts for locking the same and the propeller in any desired position being illustrated in side view.

As shown in Figs. 1, 2, and 4, indicates a rectangular metal platform or frame adapted to be placed and supported upon the rear or stern portion of a boat, B a frame carrying the propelling mechanism roperV and having a hinged connection Wit said platform A, but provided with means for securit in vertical positiomas in Figs. l and 4 and as required for` propulslon.

I will now proceed to describe the details of construction, arrangement, and operation of the parts A and B, together with those attached thereto. The platform A rests horizontally u on the stern-deck of a boat or upon the ffameworkvthereof and is secured in place mainly by means of two bars 1, (see Figs. 4, 5, 6,) Which are arranged transversely beneath the platform A in suitable guides or keepers 2, in which they may be clamped by means of screws 3. The outer ends of the bars 1 are curved to form what may be termed goosenecks 4 andprovided with clamp-screws 5.v In practice these bars are drawn out and the goosenecks 4 applied to the gunwales or side ledges of the boat or to other fixed portions of the latter and clamped by the screws 5. Screws 3 being then also tightened, the platform will be secured rigid y in the required position with its sides equidistant from the sides of the boat.

The part B, in which the propelling mechanism is sup orted and has its bearings, comarts, which have a rises the ollowing inged connection wit the platform A at a, 1, by means of a broad bracket or arm 6: The ropeller 7 is mountedl upon a horizontal s aft 8, having a bevel-gear 9, which meshes with a corresponding one, 9a, keyed upon a vertical shaft 10, which is driven from the horizontal shaft 11, having its bearings in a box 12, secured upon the platform A. Thel base of the bearing 12 (see Fig. 7) may be solidly constructed and the upper portion thereof constructed as a cap 12a, the driving-shaft 11 having a series of collars 11, running in suitable grooves in the respective parts 12 12a. -An oil-box 13 is provided in the upper portion of the bearin and communicates with theshaft and col ars by suitable ducts, as shown. shaft 11 is communicated thereto by any suitable means or motor, the same being arranged on the latformAor otherwise, as conditions and 1nd ment may dictate. -The driven shaft 10 as its' upper bearing in a tube 13, which is fixed in the four-armed bracket or frame.. (Illustrated in Fi i. 8.) Such bracket and the tube 13 ,before re erred to, constitutethe main portions'of the hinged part lB. The tube 13 is held in the upper ring 14 of the bracket, and the curved arm 15 of the latter is provrded at its lower end with a smaller ring 16, which is alined with the upy er one, 14. The lower ring 16 constitutes a earin for a hollow rotary shaft 17, the upper en of the same projecting into the lower roo4 IIC.

vss

portion of the fixed tube 13 and provided with antifriction-bearings, as will now be described. Thus the rotatable tube 17 is provided with a horizontal flange 18, which is inclosed in a circular box land arranged between antifriction-balls, as shown in Fig. 1. The said box is formed by enlarging the lower end of the tube 13 and providing it With a pendent internally-threaded flange into which the vertical flan e of a short tube 19 is screwed, as shown. y this arrangement an antifriction-support is obviously grovided for the rotary shaft 17. n antiiction-bearing, whereby it is held in vertical position, is further provided by means of rollers 20, (see Fig. 9,) having their bearings in the sides of theixed tube 13 and the removable short tube 19. In other words, the rollers 20 work in contact with the side of the shaft 17, being held rotatably in recesses provided in the parts 13 and 19. The shaft 17 is connected with a horizontal bearing 21, which constitutes a bearing for the propeller-shaft 8. The latter is provided with a collar21, abutting a sleeve 22, whose inner threaded end is screwed into the adjacent internallythreaded tubular portion of the bearing 21.

By this means the gear 9 of the propellershaft 8 is held duly engaged with the gear 9@l of the driving-shaft 10. It is obvious that this means provides for taking up wear at any time, so that the ears are held duly in mesh. To further provide for a nice adjustment of the propeller-shaft, I arrange a set-screw 23 in the inner solid portion of the bearing 21, the same abutting the inner end of the said shaft. The outer bearing of the shaft is rovided by a collar 24 and a cap 25, whic is threaded internally to adapt it to be screwed on the tubular nut '22 and also incloses the said collar 24. By this means I provide for such adjustment of the bearing as may be required from time to time. Beneath the propeller7 I arrange a guard-plate 26, whose inner end is kprovi ed with a screw-stem 27, by which it 1s secured in the lower pendent tubular portion of the bearing 21.

It is apparent that by applying power to the driving-shaft 11 the vertical shaft 10 will be driven correspondingly and the propeller 7 thereby rotated with like speed, provided the meshing gears be of like size as in this case. justed in line with the axis of the boat, the propulsive effect will obviously be applied in the same direction; but by means of the rotatable shaft 17 and the bearings therefor lic-- vfore described the propeller may be shifted around the axis 10 at any required angle for guidin the boat in different directions, so that w en desired the function of a rudder is performed by the propeller in addition to its ordinary function. For adjusting such shaft 17and thereby placing the propeller at dil'- ferent angles, as may be required, l employ Assumln that the bearing 21 be ad-v the following means:` A vertical shaft 28 is arranged in bearings 29 (see Fig. 8) of the curved portion or yoke 15 of frame B and provided at the top with a steering-wheel 30 and near its lower end with a gear 31, that meshes with a correspondin gear 32, keyed upon the hollow shaft 17 an arranged above the lower ring 16 of the frame B. It is apparent that by rotating the shaft 28 through the medium of the steering-wheel 30 the shaft 17 may be rotated while the propeller 7 is at rest or in motion for setting the propeller at any angle to the axis of the boat as may be required for steering the latter in any direction. A foot-platform 33 (see Figs. 1 and 4) .is provided for the steersman, the same being rigidly attached to and supported by the tube 13. In other words, said foot-platform 33 forms a rigid attachment of the hinged portion B of the apparatus.` In connection with the steering-wheel and the shaft 28 I provide means for locking them in any required position, so that the propeller 7 may be set at any required position and then locked in said position. As a rule. the lock will be applied for lholding the pro eller with its shaft in line with the axis of t e boat, in which case supplemental steering mechanism will be utilized. The locking means are as follows: Aratchet-collar 34 is secured upon a fixed support of the platform 33, and a lever 35 is pivoted to an arm pendent from the steering-wheel 30. A spiral spring 36 presses the inner end of said lever into engagement with the ratchet 34, and a push-bar having a head 37 is attached to the other end of tlie lever, so that by depressing it the steeringwheel and shaft 28 are unlocked.

I provide a supplemental and manuallyoperated steering mechanism, the same consisting of a rudder 38, (see Fig. 1,) having a vertical shaft 39, which -is pivotally attached at 40 to the yoke 15 of frame B and' provided at its upper end with a cross-bar 41, from which cords or wires 42 extend forward through guides 43 on the platform A to the shaft 44 of a hand steering-wheel 45, the said shaft having its bearing in a suitable bracket 46, forming an attachment of the front end of the platform. It is apparent that by rotating the wheel 45 a boat may be steered by means of the rudder 38 without recourse to the propelleradjusting mechanism before described, and, on the other hand, if the rudder be left free-the boat may be steered by means of the propeller, as described.

position, 'as shown in Figs. 1, 3, coincidin with holes in vertical lugs 47, forming rigi portions or attachments of the rear end of the platform A. Clamp-screws 48. passing through the coincident openings of the parts 15a and 47, serve to secure the frame B and its attachments in the vertical working position. (Indicated in Figs. 1 and 4.) By removing such fastenings 48 the whole hinged portion of the apparatus may be swung on the hinge a in the position beneath the platform and practically parallel thereto. words, the part B and all its attachments may be folded together with the platform A when detached from a boat, so that the same will occupy a minimum space, as required for transportation or storage. For securing the parts in the folded position a strap 49 may be passed under the hollow shaft 17 and through slots provided in lugs 50, that are pendent from the side edges and front portion of the platform A. When the part B and its attachments are thus folded, the transverse bars 1, by which the platform is vsecured to the boat, are drawn out of the keepers 2 and inserted in keepers 2, (see Fig. 1,) so that they are held longitudinally parallel to the platform instead of being transverse thereto.
