MOTOR SUPPORT Filed Nov. 4, 1929 Patented Apr. 28, 1931 UNED STATES PATENT OFFICE FINN T. IRGENS OF MILWAUKEE, WISCONSIN, ASSIGNOR TO OUTBOARD MOTORS COR- PORATION, OF MILWAUKEE, WISCONSIN, A CORPORATION OF MICHIGAN MOTOR SUPPORT Application filed November 4, 1929. Serial No. 404,570.

This invention relates to improvements in motor supports. i

It is the object of the invention to provide a novel and improved means for carry- 5 ing an outboard motor in a recumbent position (when not in use) without injury to its fuel tank.

When outboard motors are laid down for any purpose, as for transportation, or as an incident to manipulation in positioning or removing the motors. from the boat, the motors are ordinarily laid upon the ground with the tiller handle uppermost. The design of outboard motors has heretofore been such that in the position aforesaid, the fuel tank of the motor has contacted with the ground and has been subject to dents, scratches, and cuts which mar its appearance and tend to loosen the tank from its support and to cause it to leak To overcome these objections I have provided extended cooling fins on the muffler heads which perform the function of feet and project from the mufiler beyond a plane including the surface ofthe fuel tank and the point of support at the lower unit of the motor.

In the drawings:

Figure l is a side elevation of a motor. supported in accordance with this invention.

Figure 2 is a detail in perspective of the mufiier shown in Figure 1 and exemplifying one way in which suitable supporting feet may be economically and inconspicuously formed on theimotor.

Like parts are identified by the same reference characters in both views.

The outboard motor comprises a supporting bracket 5, bearing sleeve 6, tubular support 7, engine 8 and lower unit 9. p The engine is provided with the usual fuel tank 10 and fly wheel magneto 11. The engine crank shaft is not illustrated but it will be understood to be extended through the tubular support 7 in the usual way and connected to drive the propeller 12.

When the motor is in a recumbent position, as illustrated in Figure 1, its lower unit is usually supported by the propeller 12 or the propeller nut 13. In accordance with this invention the engine is provided with a means of support other than fuel tank 10 for keeping the upper end of the motor sufficiently remote fromthe ground so that the fuel tank will not contact therewith.

For this purpose, I provide the usual heads 14 and 15 of the mufiier 16 with feet inder castings of the engine in accordance with usual practice, it will be obvious that the muflier itself, which is usually made of sheet metal, is relieved of load in addition to the relief afforded to the fuel tank. The muffler, however, is entirely adequate to brace the heads against displacement under any load to which they are subjected in performance of their new function of supporting the motor.

I claim: I

1. In an-outboard motor, the combination with an engine having a fuel tank so positioned as to lie therebeneath in the recumbent position of the motor, of a m'ufller for 'said engine provided with vents in its intermediate portions and supports for said engine adjacent the ends of the muflier and projecting beyond said tank and intermediate portions of the muflie'r, whereby to be adapted in the recumbent position of the motor to hold said tank and vented mufiler portions off the ground.

2. In an outboard motor, the combination 4 with an engine and a lower unit connected therewith and provided with means adapted to rest on the ground in the recumbent position of the motor, (if a fuel tank for said engine positioned to lie therebeneath in said motor position, a muffler likewise located to lie beneath said engine in the recumbent position of the motor, and members at the ends of the muffler connected with said engine and provided with supports extending beyond the muffler and fuel tank, whereby to carry the weight of the engine and to relieve the tank and mufiler thereof.

3. In an outboard motor, the combination with an engine and a lower unit connected therewith and provided with means adapted to rest on the ground in the recumbent position of the motor, of a fuel tank for said engine positioned to lie therebeneath in said motor position, a mufiler likewise located to lie beneath said engine in the recumbent position of the motor, and members at the ends of the mufller connected with said engine and provided with supports extending beyond the mufiier and fuel tank, whereby to carry the weight of the en e and to relieve the tank and mufiier t ereof, said members comprising exhaust manifolds for said engine.

, 4. In an outboard motor, the combination with an engine and a lower unit connected therewith and provided with means adapted to rest on the ground in the recumbent position of the motor, of a fuel tank for said engine positioned to lie therebeneath in said motor position, a muflier likewise located to lie beneath said engine in the recumbent position of the motor and members at the ends of the muflier connected with said engine and provided with supports extending beyond the mufiler andfuel tank, whereby to carry the weight of the engine and to reheve the tank and muflier thereof said members comprising exhaust manifolds forv said engine having cooling flanges extended to provide said supports.

5. In an outboard motor having-cylinders at opposite sides of a central axis, the combination with said cylinders, of engine supports connected therewith substantially at the ends of said cylinders and pro'ecting rearwardl at widely spaced points whereby to carry t e weight of the cylinders directly and provide sta le engine support in a recumbent motor position, and exhaust gas mufiler means having lessrearward extent than said supports, whereby to be protected by said supports in said motor position.

6. In an outboard motor having engine cylinders with these ends widely spaced laterally,-the combination with said-cylinders,

. of exhaust manifold castings connected with the cylinders near their ends and provided with rearwardly extendin feet for the directsupport of said cylinders in recumbent motor ositions, and exhaust means less remote om said cylinders than said feet, whereby to be protected in recumbent motor positions.
