ERNEST HAMILTON HEINKE, OF LONDON, ENGLAND.

BOAT-PROPELLING MECHANISM.

To all whom it may concern:

Be it known that I, ERNEST HAMILTON HEINKE', a citizen of the United Kingdom of Great Britain and Ireland, and resident of 54 South Molton street, London, England, have invented certain new and useful Improvements in Boat-Propelling Mechanism, of which the following is a specification, such as will enable others skilled in the art-to which it appertains to make and use the same.

This invention relates to motors and propellers for attachment to boats and other floating bodies andrefers to that type of machine in which an internal combustion engine or other motor arranged above the waterline is adapted to drive a vertical shaft, the lower end of which is in gear with a propeller below the water line.

, The invention concerns particularly a better arrangement for mounting the appliance upon the boat or other floating body where by it can be entirely raised from the water and placed upon the deck or equivalent of the boat. r

The invention also includes details of construction relating particularly to the arrangement for steering, the brackets emloyed for mounting the motor andaother eatures hereinafter described and claimed.

In the accompanying drawings, Figure 1 the bracket for supporting the motor in operative position, and Fig. 6 is a plan of the same when in the position of Fig. 5.

Referring to Fig. 1, the motor T is attached by means of bracket Rand screw W to the stern or transom N of the boat. The motor drives pinion which is in mesh with pinion P on the vertical shaft B, the said shaft being inclosed in the hollow shaft E and having at its lower end the pinion J in meshwith pinion K on shaft L to which the propeller is fixed. Pinions J and K are contained in the gear case A which has an extension C in line with the hollow shaft E Specification of Letters Patent.

Application filed June so, 1913. Serial No. 776,622.

and is adapted to be turned by means of a cog wheel F which is keyed to the extension C and is in mesh with the wheel G 'on the shaft S, the said shaft being adapted to be turned by any suitable means such as a flexible shaft to which it may be connected.

It will be seen from Fig. 2 that the wheel F is keyed to the sleeve or extension C and .it will be obvious that if the wheel G is turned by shaft S it will rotate wheel F and thereby swing the propeller around and thus enable the boat to be steered, or driven astern.

The wheels F and G are inclosed in the case H to which the V-shaped or angle bracket. N is pivotally fitted, the said bracket being composed of two symmetrically disposed members each consisting of an inner part pivoted at its inner end to the pivot U' and resting, When' in operative position,

with its lower part on the stop V on the stern of the boat. When the'appliance is moved' from operative to inoperative posi. tion, the whole appliance is swung over onto the deck,'the. bracket M pivoting on the pivot U.

In Fig. 3 the steering and reversing gear is arranged close to the motor and the drawing clearly shows how the appliance can rest on the deck Z of the boat.

'-In Fig. 4 links R pivoted at R to the motor and at R to brackets on the deck Z' are used in place of the bracket and screw R, W, shown in Fig. 1."

It will be observed that the peculiar formation of the bracket M permits the appliance being turned well over on to the deck and also that the shape of the bracket allows the propeller to be swung completely around and placed under the bracket for driving astern in addition to which the forward drive of the propeller is conveyed in very direct manner to the boat.

Obviously instead of placing the appliance on the deck it can be received upon any suitable upport.

What I claim and desire to secure by Letters Patent is:

1. In a. boat propelling mechanism, the combination of a motor; a propeller operatively connected thereto; a link pivotally connecting the propeller to the boat; and a loigk piyotally connecting the motor to the 2. In a boat propelling mechanism,-the

combination of a motor; a propeller operatively connected thereto; and a pair of links, one above the other, pivotally connecting the motor and propeller to the boat.

3. An appliance for use with boats comprising an outboard motor and a propeller, a pair of pivoted links supporting the motor and a pivoted bracket of substantially double V shape supporting the propeller, a

shaft between the motor and the propeller, a toothed gear on the motor, a toothed gear on the propeller, a toothed gear on the upper end of the shaft co-acting with the toothed gear on the motor, a toothed gear on the lower end of the shaft co-acting with the toothed gear on the propeller, and means whereby the propeller can be rotated around the axis of the shaft.

4. An appliance for use with boats comprising an outboard motor and a propeller, a pair .of pivoted links supporting the motor and a pivoted bracket of substantially double V shape supporting the propeller, said bracket extending from its supporting point of the propeller to stops fixed to the boat and upwardly therefrom to the pivots whereby it is connected to the boat, a shaft between the motor and the propeller, a toothed gear on the motor, a toothed gear on the propeller, atoothed gear on the upper end of the shaft co-acting with the toothed gear on the motor, a toothed gear on the lower end of the shaft co-acting with the toothed gear on the propeller, and means whereby the propeller can be rotated arour the axisof the shaft.

5. An appliance for usewith boats com prising an outboard motor and apropeller, bracket supporting the motor and a brack pivoted to the boat and the propeller, shaft between the motor and the propelle a toothed gear on the motor, a gear on tl upper end of the shaft co-acting therewit shaft for rotating said toothed gears on tl sleeve. to effect the turning of the propelle 6.. An appliance for propelling boats con prising a motor, combined with and adap' ed to drive a propeller, the said applianc being connected to the boat by means of V-shaped bracket and links pivoted to tl appliance and to the boat whereby the a pliance can be raised and swung over 1 rest upon a support in the boat.

In witness whereof I have hereunto s1 my hand in presence of two witnesses.
