June 7, 1960 P. ROEMER OUTBOARD MOTOR MOUNT Filed Jan. 9, 1959 INVENTOR. PETER ROEMER ATTORNEY United States Patent() ice OUTBOARD MOTOR MOUNT Peter Roenier, 1822 W. Lombard, Davenport, Iowa Filed Jan. 9, 1959, Ser. No. 785,836 7 Claims. (31. 248-4) This invention relates to a mount for supporting a typical outboard motor on the back or transom of a boat and more specifically aims to provide anovel, improved and relatively inexpensive mount having many advantages over known types of mounts.

Ordinarily, an outboard motor is removably clamped to the boat transom, but more recently several types of mounts have become available, having as their purpose the provision of an intervening support enabling swinging of the motor between an upright or normal operating position and a transport or generally horizontal position clear of the water. 1 Mounts of this type are desirable for many reasons, such as to elevate the motor in shallows or in weedy conditions, to transport the motor when rowing, etc., to afford access to the motor propeller and so forth.

Although these purposes have been served generallyby the prior art, these former mounts leave much to be desired in the way ofsimplicity, initial cost, ease of operation and installation. Accordingly, the present invention has for its principal objects the provision of a simplified low-cost design providing for easy installation, the use of pin and slot means. for. not only pivoting the motor but for enabling bodily shifting thereof as incidents to locking and unlocking same from operating and transport positions, plus provision for readily adapting the structure to: difierent types of boats.

The foregoing and other important objects and desirable features inherent in and encompassed by the invention will become apparent as a preferred embodiment thereof is disclosed, by way of example, in the following description and accompanying sheet of drawings, the several figures of which are described below.

. Figure l is a fragmentary elevation of the mount in use as carrying an outboard motor in operating position on the transom of a boat.

Figure 2 illustrates-the same'structure but shows the transport position.

Figure 3 is an enlarged plan of the mount, absent the motors v Figure 4 is a section on the line 44 of Figure 3 and shows in full lines an upwardly shifted position of the motor-carrying element and in dotted lines another position of said element.

Figure 5 is similar to Figure 4 but shows in full and dotted lines two other positions of the motor-carrying element in its change between operating and transport positions.

'Those familiar with the art will recognize the rear part or. transom ofa boatat and a typical outboard motor at 12. Since this much of the disclosure is or maybe regarded as conventional, details will be omitted and the ensuing description will proceed with descriptive terminology based on the rearward location of the motor and the further recognition that the transom is transverse to the fore-and-aft length of the boat. The detailsof the improved mount, designated as a whole by the numeral 14, will be related location-wise to the r 2,939,658 Patented June- 7, 1960 it should be understood that this is for clarity and brevityand not for the purpose of unduly limiting the scope of invention.

The mount 14 is made up of a forward support or bracket 16 of U shape as seen from above, having a transverse bight 18, including means such as bolts 20 for aifixation to the transom 10, and a pair of transversely'spaced apart rearwardly extending legs 22. The support is preferably a one-piece sheet steel structure, the bight 18 being suitably apertured for the bolts 20 and the legs-22 assuming a rectangular upright platelike character. The heads of the bolts 20 may be countersunk if desired. However, any form of affixation may be used. 7 1

The legs 22 have a pair of transversely alined upper apertures, 24'which carry an "upper rod or pintle 26,

which maybe removably retained as by cotters 28. These legs further have a plurality of pairs of lower apertures 30','any selected alined pair of which may carry areniovable lowerrod or pintle .32, retained as '.48,,and thesejslots receive the upperrod or pintle 26..

by cotters 34. As will become clear later, the plurality of vlowerapertures 'afltord several fOI'e-filld-flft settings or adjustable meansfor the lower rod 32.

The motor-carrying part of the mount 14 comprises a rearward bracket or element 36 having a' transverse bight 38- and a pair of forwardly extending legs 40. Thiseleinent, like the element 16, is preferably of sheet vsteel and the bight 38. may be appropriately apertured tosupport ablock 42 to which the motor 12 is'clamped by .itsconventional clamp means. The legs 40 are generally rectangular-and plate-like and are transversely spaced apart-so that they he respectively laterally inwardly of a'ndalongsidethe support legs 22. T 1 I Thefbracket legs40 respectively. have upper trans:

versely alined L-shapedw slots 44, each having an upright or firstlpart.46 and a second rearwardly extending part The legs 40 further have transversely alined lower notches '50 which open downwardly to' receive the lower rod 32 in operatingposition (Figure 1), at which time the upper rod is at the upper ends of the upright slot parts 46 and thelower rod is at the upper ends of the notches 50; Thus, the bracket 36 is releasably locked inits 'operatingjposition and the motor and boat may be operated just as if the motor were carried directly on the transom without the intervention of the mount 14.

However, this mount serves many useful purposes, as will be, brought out presently.

Whenflthe bracket 36, carrying the motor 12, is shi fted upwardly (full lines, Figure 4) via the upright slot parts '46, the lower notches 50 become freed from the lower rod 32 and the bracket may be swung rearwardly so that the lower front ramp-like corners 52 of the bracket legs 40clear the rod 32, after which the lifting eflort onthe bracket and motor may be relaxed, and

" the bracket will; drop to the dotted-line position of Figapproximately 90 away from that of Figure 1.

ure 4, wherein the bracket is now supported exclusively by the upper rod 26 and the upper ends of the slot part s 46. This efiects a pivotal connection between the support 16 and bracket 36 and the latter may be swung upwardly and rea'rwardly to ultimately assume its trans on the rod 26 still occurs at' the upper (now forward) ends of the slot parts 46, shifted bodi-ly forwardly until the rod 26 now registers with the second (now generally upright) slot parts 48, whereupon the bracket will drop to the transport position of Figure 2, the rod 26 no'w occupying theclosed ends of the slot parts 48'.- When this occurs the upper front corner portions of the legs 40,- as at 54'; abut rear face portions of the bight 18 in areas below the axis of the rod 26 and these portions 158 and 54 thus constitute eng'ageable portions cooperative upon downward shifting of the bracket 36 from the full-line positionof- Fig ure to the transport position (Figure 2) to lock the bracket against tipping out of a transport position; It should be observed atthis point that: there is a sl-ight rearward and upward angle to the now generally upright slot parts 48, and this accentuates the. locking phase of the mechanism as will be obvious.

after which the bracket is When it is desired t'o returnthe bracket 3 6'and'motor to operating position, the bracket is lifted via the slot parts 48 to release the portions 18 -54 and to, attain'first the full-line position and then the dotted-line position of Figure 5, the bracket shifting rearwardly and downwardly so that the rod 26, seats in theclosed (now' forward) ends of the slot parts 46. The bracket then swings downwardly and forwardly to the dotted-line position of Figure 4 and at thispoint the ramp portions 52 at the lower front corners of the legs 40 become effective to ride up over the rod 32 so as to facilitate re-engagement of this rod by the notches 5t}, and there upon the bracket will drop from the full-line position of Figure 4 to the operating position of Figure 1. Thus, the notches Strand rod 32 function as lock means engageable to retain the operating position of the bracket 36 and disengageable to enable swingingof the bracket and motor out of operating'position. This lock means is engageable when the bracket 36 shiftsdownwardly to operating position and is releasable when the bracket is lifted from said operating position. The other lock means, made up of the leg p'ortions54 and rear face portions of the bight 18, is engageable when the bracket 36, after being pivoted upwardly and rearwardly, is moved downwardly and is releasable when the bracket is lifted preparatory to being returned to operating position. These lock means are incorporated in the structure and need not be furnished as additional movable components. Also, the pin andslot means 32-44 enables not only pivoting of the bracket 36 but also bidirectional shifting in two angularly related paths.

Since transoms in various boats vary as to angle relative to their bottoms, the motor may not occupy the proper status in operating position if its status were dependent entirely on one location of the rod 32. Hence, adjustment is provided here by means of selectively relocating the rod 32 among the several pairs of lower apertures 30. This avoids the need for complicated adjustable means between the support 16 and transom 10.

The mount may be manufactured in a variety of sizes to accommodate motors of different sizes. Likewise," on the basis of the present disclosure and present and subsequent knowledge of the art, other alterations may be made in the preferred embodiment of the invention without departure. from the spirit and scope of the invention.
