Aug. 30, 1932. J. w. HARVEY MOTOR INSTALLATION 2 Sheets-Sheet 2 Filed July 13, 1931 Patented mi. 3a 1932 waste moron msrnna'rron Application filed July 13, 1931. Serial No. 550,303.

My invention relates particularly to means for installing what is commonly termed an outboard motor inside of a boat.

One object is to provide a simple and in- 55 expensive construction" involving improvements on the invention of my Patent 1,786,997.

A special object is to provide a simplifiedmounting for the motor in the casing. Another object is to provide means of construction such that the motor can be readily removed or installed in the casing.

Another object is to provide an improved automatic drain. I Another object is to provide means for draining the boat as well as the casing when the boat is in motion.

Fig. 1 is a longitudinal sectional view of a casing and side elevation of a motor and showing the propeller and its carrying frame retracted in dot and dash lines.

Fig. 2 is a transverse section of a boat on a very small scale showing an installation em- 'bodying my invention. Fig. 3 is an enlarged cross section of the casing showing the drains and engine exhaust.

Fig. 4 is a transverse section of the pro- 4 peller housing.

Fig. 5 is a plan view of the casing and Showing the propeller housing and frame in section.

Fig. 6 is a diagrammatic .plan of a modification.

The casin may be formed of suitable material such or instance as cast metal having a side wall 7, a bottom wall or floor 8 and .a projectin flange 9 for attachment to the bottom of a %oat or the walls mightbe parts of f the boat structure. The bottom of the casing has an opening 10 in its rear end which is preierably circular, and which is normally closed by bottom plate 11. A resilient asket 12 to instance, of rubber, serves as g g I a yielding s pport for the bottom plate and attached parts. I

The motor 14 may be of any suitable type usually provided witha control handle such as 15, and with-the cylinders and fly wheel at the top. The-vertical housing 16 contains the shaft and gear connection to the propeller 17 and supports the motor cylinders and associated parts. The motor may be supplied with coolin water for instance, through a pump 18. he propeller shaft housing may also carry the exhaust passages and have an outlet such as 19. The guard 20 serves to protect the pump and propeller. Features of the housing 16 and its various passages are more fully shown and claimed in my appliso cation 582,980, filed December 24, 1931.

The motor is supported by a frame of which the bottom plate 11 is a art. The sleeve 21 in which the propeller ousing 16 is supported and preferably rotates is secured to the bottom plate in any suitable manner,

for instance by a flange 22, which may be riveted, bolted, welded or integral with the bottom plate preferably at its front ed e. A bracket or arm 23 has upper and ower branches at its rear end secured for instance by cap screws 24, to the front side of the a sleeve 21 at its upper and lower ends respec-v tively. The front end of this bracket is piv otally' supported by lugs 25, which may be, 7 cat integrally with the bottom and front wall of the casing. The pivots are formed by pins such as 26, which are detachably mounted in the lugs 25 so that they may be readily retracted for disconnecting the arm from the casing. These pins may have finger pieces 27,

to facilitate retraction and they ma be supported by sprin strips 28 for holding them yieldingly and etachably in position. The

upper part of the sleeve 21 is preferabl split and provided withflanges 3O adapte to be drawn toward each other bya screw 31, so

as to vary the frictional resistance of the shaft housing inside the sleeve and thus control the resistance to rotation of the engine and propeller on a vertical axis. The propeller housing has a collar 32, which rests 'on the upper end of the sleeve 21 to support the welght of the motor and'propeller. The length of the. bracket 23 is referably less than'the height of the casin i so that the motorand tliepropeller may e tilted about'the single axle of. the hinge pins 26 in such a manner that the propeller and the lower end of the housing can be retracted within a space. 10o

1 drain outlets is' preferably -connected by means of a ipe 37, to the inside of the boatv outside of t e casing where a screened inlet 38, is provided. This pipe 37 maybe a flexible rubber hose secured on to the end of a nipple 39;, projecting upwardly from the suc-' tion outlet 36.

i The motormountmg is so constructedthat it maybe readily tilted into the dot and dash line of Fig. I for the purpose ofinspection,

' Q repair, or replacement of the propeller. The

.7 motor will also automatically be thrown into this position in case the propeller housing or guard. strikes an obstacle. When the obstacle strikes the guard 20, the tendency is to swing the propeller housing and motor about the pivot 26, and as soon as the arm 23 is raised at all, the forward inertia of the motor and the upper end of the propeller housing tends to move these parts forwardl so that the retracting action is facilitate by the check- I in of the movement of the boat.

is in motion. In this construction the casing 7 is preferably. open at the to so that any leakage of or oil from t e motor, or its supply- 4 tank, can-fall directly into the casing and not "into the boat. When the boat is moving the water in the easing as well as the water outside of the casing, but inside of the boat, is drawn out through the suction outlets and 36 so as to maintain buoyancy and dryness of the boat and casing. I

For transportation purposes it is a very simple and quick matter to detach the entire 'motor and its supporting frame by simply retracting the pins 26 b one hand.

By locating both oft e drains in the bottom of the movable plate, it will be seen that they are both automatically lifted clear of the bottom of the boat when the-motor is lifted and the bottom of the boat is thusleft clear and free from obstructions.

In the form shown the casing is provided with downwardly projecting longitudinal ribs 40 extending substantially the length of the casing from front to rear on each side.

These ribs serve several functions, i. e.,- reinforcement to the casing per se, guards to rotect -the' drain-outlets, and stabilizing eel sectlons- These ribs may be cast integral 'ly' with the casing and while they add very "bottom of said casing to en the motor is dropped down into place the gasket 12 serves as a cushion to prevent shock. This also makes it possible to main- 35 mm a nearly water-tight seat when the boat neveesa little to the amount of'metal required they materially strengthen the bottom of the easmg. a Y In smaller boats the casing might 'fill the entire width of the boat, or the rear or other portion of the boat might constitute the casing. In such a case transverse bulkheads d1,

42 might constitute the front and rear walls v of the casing, and the sides &3 of the*boat or longitudinal bulkheads might constitute the side walls. The motor frame,the supporting plates, the drainage and the tiltin action would be the same as above describe I claim: 4
