F. WELLER v MOUNTING FOR OUTBOARD MOTORS Filed Oct. 22. 1927 lizf nfor Frank eller Patented Feb. 21, 1928.

FRANK WELLER, 0] SAN DIEGO, CALIIORNIA.

MOUNTING FOB OUTBOARD MOTORS.

Application filed October 22, 1927. Serial Io. 287,964.

In the use of outboard motors of the type now extensively employed in the propulsion of boats, it is the customary practice to clamp the motor to the stern-board of a boat, and entirely outside of and behind the hull, so that in this position, the motor is exposed to the action of the elements and is also exposed to tampering on the part of unauthorized persons. In these circumstances, it is either customary to bodily remove the motor for safe-keeping, or to cover it over with a rubber jacket or other protective covering, but either method of handling the motor is objectionaLe for obvious reasons. 1

Furthermore, the motor in full view at the stern of the boat presents a more or less unsightly appearance which is offensive to the nautical eye, in that it encumbers the stern of the boat with a protuberance which breaks the stern lines and impairs the appearance of the boat as a whole. In the use of o'utboard motors at the present time, it is seldom the practice to construct the boat to afford amounting for the outboard motor which has heretofore been largely treated as an accessory feature to be app ied to row boats or other craft of conventional design.

The object of the present invention is to so construct the stern of a boat as to afford an especially adapted mounting for the outboard motor which, according to the present invention, is in a sense built into or especially fitted to the boat itself, and is so concealed andprotected that it may be treated as a constituent portion of the boat itself in much thesame sense as a motor and ropeller which are permanently built into t e structure of a boat. At the same time, the pres ent invention provides for the ready application of the motor to and itsremoval rom the boat, so that the motor possesses allof.

I p the advantages of a unitary and self-contained power unit without any of the disadvantages which have heretofore accompanied the use of outboard motors.

Further objects and details will appear from a description of the invention in conjunction with the accompanying drawing.

.Figure 1 is a-perspective' sectional view of the stern of a boat showing the motor in propelling position and, indicating in dotted mes the position occupied by the motor 1 when lifted; and

y at

Fig. 2 is a deck plan view of the same. The motor 10 is conventionall illustrated, since it may be of any usual an "well known type now on the market, comprising, as is usual, a fly wheel 11, gasoline tank 12, and propeller 13 with asteerin fin 14, the parts eing carried b a vertical y elongated shaft housing 15,, w ich hassecured' thereto a hook-shaped bracket 16 carrying clamping screws 17 of the usual character. These features of the outboard motor are common in one form or another to .various makes of.

a water tlght bulkhead 20 which traverses the hull of the boat at a point considerably in advance of the-stern-board or transom 21, said bulkhead being located, in the present instance, at a point immediately above' the stern 0st 22. The sup orting board may be loc ed in vertical position by a latch '18 or the like. The stem of the boat overhangs rearwardly from this point and the boat, as

shown, is timbered to afford a rearwardly extending center beam or timber 23 which is provided with a longitudinally extending slot 24 of suitable wi th to permit the tilting of the shaft housing and propeller from the operating position shown in full lines into the housed position indicated in dotted lines.

When the motor is in its operating position, the foot 25 ofthe hook-shaped bracket will abut squarel against the bulkhead 20 so as to afford a firm contact against a rigid structural portion of the hull during operation, and it will be observed that the hinged board 18 need occu y the medial portion only of the bulkhea to afford a suflicient area for the rigid clamping of the hooked bracket in position. This portion only of the structure is hinged or otherwise tiltably mounted to provide the necessary mounting for the motor.

The overhanging stern portion of the hull is provided with a deck 26 which, as shown, is out out at the line 27 slightly to the rear of the bulkhead to afford open access to the when the two doors are lowered to bring their edges together, they will, in unison,

constitute a continuation of the rear deck structure and completely cover over the motor when in the housed position indicated in dotted lines.

The hull of the boat, in advance of the bulkhead 20, as shown, is provided with a flat forwardly extending seat 29 which preferably ext-ends forward to the same degree as the doors 28, and, as shown, abuts on each side against a side bulkhead of segmental formation which is fitted into the boat at this point. It will be understood II that the drawing illustrates but one half of the hull structure and that the same structure is duplicated on each side. As shown, each segmental bulkhead 30 has hinged to its inner edge a door section 31, the two sections being of a size to completely close across the hull and wall off therear portion of the hull in alignment with the side bulkheads, which latter may, if desired, be formed integrally with or as continuaao tions of a forward center bulkhead 32 located beneath the seat 29. Obviously, the structural arrangement of the bulkheads and doors may be varied more or less to conform to the timbering .of the stern of the 30 boat, but in each case the parts will be pro-' portioned and fitted in such a way as to afford the necessary space and clearance to permit the motor to be tilted from the upstanding position to the horizontal position, in which latter case the motor will rest upon and be supported by the seat with the propeller end of the motor lifted upwardly through the slot 24 and housed within the overhang of the boat.

11 The door sections 31 will be of the'proper dimensions to swing rearwardly from the position indicated in full lines to a position at right angles thereto in which latter position they will underlie the hinged edges of the deck door sections 28, so that when thus adjusted and with the deck door sections swung clear back to lie upon the deck, the

motor will be fully exposed, and the seat 29 will be open for occupancy by the operator or navigator of the boat.

When it is desired to house the motor, the door sections 30 will first be swung forward into the osition indicated in the drawing after which the motor will be tilted into horizontal position with its upper end rest ing upon the seat 29, after which the door 28 may be swung down to rest upon the upper edge of the doors 31 to which they may be padlocked, thereby completely housing and enclosin the motor, so that it will not only be in ly protected against the weather, but will also be protected against tampering or removal by unauthorized persons. an Furthermore, the motor when in c ient hanging stern provides deck space and thus affords a hull form particularly desirable in the case of sailing yachts which must be designed to afford adequate deck space for the manipulation of sails and rigging.
