This invention relates to motor mountings.

It is among the objects of the present invention to provide a novel and improved mounting for outboard motors for motor 7 A further important object of the present invention is to provide an outboard motor mounting whereby conventional type inboard motors maybe 'used as outboard motors for A further object of the present invention is to provide an improved'tiltab'le mounting for outboard motors.

Other objects of the present invention in "'15 clude the combination and interrelation of parts whereby a novel and improved motor mounting is provided which includes suitable supports and adjustable features,ial l of which will be simple, :efiicient and well ad'apt- 90 ed to meet the demands of economic manufeature. V I 1 v Numerous other objects of the present in vention will he apparent froma consideration of the following specification; taken inwhich- 7 Figure l is aside elevation efra boatpartly broken away'ian d' disclosing the present invention;

7 Referring more particularly to the drawings, the numeral 10 indicates :a boat, a sea Shd being of chosen to illustrate the lfl'escnt torr'n of the invention;

s The-boat is cut away in therear toliorm a transom 11, as indicated the top planflview of Figures. Thesides12 of "the transom 111 are provided with centrally positioned motor supporting plates 13,' leachof which" has a vertical 'slot 14 .fromjwhich extend down wardly'iextending recessed slots 15. The platcs13 are adapted tohe secured to the sides of the transom by suitableloolts, screvvs or the like, as indicated at 16in Figure 2; .v The motor generally indicated ati? is herein illustrated. as the conventional parallel vertical cylinder 'motdr; f lt Will be uh; ders-tood that the invention is notfconfined to the specific type of motor used} an important object of the invention being to provide 7 means; however, for using theconventional inboard type of motorasan outboard motor onmotor boats The motor 17 is provided Withoppositely extendinglu-gs 1 8 theends of which 'termi hate in heads 19, the arrangement being such thatthe' lugs are movable in the slot 14; to be sel'ective'ly received in thejrecessed slots. 15, the heads 19 preventing accidental movement of the lugs from the plates. f 7 i It will be understood that the 1 plates 13 are recessed'hehind the slotsto provide for the reception of the head 20. Thus it will be seen that the lugs-may be received Within the slots by vertical downwardmovement so as to have the'lu'gs enterthe selected slot 15:.

Itwillfalso' be seen that by the present er; s

rang'ement the motor may he pivotally moves, using the lugsas a fulcrum so that, as shown in dotted lines in Figure 1,the motor'ma'y be warmed up without the propeller .being in the Water. j

Forbracin-g the,plates 13 and adjusting their distance from the front 2 1 of the transom, a' substantially U-shaped hrace22 is provided secured by'bolts as at23 to the front 21 of the transom. 'The ends of the brae'e' are channeled-toreceive therein pare allel braces 24extending forwardly from the plates 13. The braces 24 are drilled as at 25 to receive therethrougha securing bolt 26 carried by the brace 22.

For securing the motor in proper tilted position as shown in Figure 1 whereby the propeller will be in the water to propel the boat, a pair of vertical brackets 27 are provided on the sides 12 of the transom and rearwardly from the plate 13. The brackets 27 are apertured as at 28 to receive there through a securing bolt 29 which passes through the upper ends 30 of upwardly and downwardly extending tie rods 31, the lower ends of which are secured by a bolt 32 to the extended casing 33 of the propeller shaft 34, as shown most clearly in Figure 4c of the drawings.

From the foregoing it will be readily seen" that the present invention provides an adjustable mounting for outboard motors, the arrangement providing for the pivotahsupport of the motor and being adjustable longitudinally in the transom to accommodate various sizes of motor length. 7

By the use of the present invention-it will be understood that the boltsr29 are 'discon nected, thus permitting tilting movement of the motor. The motor can then be tilted to the position shown in dotted lines in Fig ure 1 and warmed up without movement of the boat. When themotor is in the proper operating position it is tilted to the position shown in'full lines in Figure 1, the bolts 29 are secured in the selected aperture 28, thus maintaining the motor in properly adjusted position. I

Referring more particularly to Figures 5 and 6 of the drawings, it-willbe seen that the invention is adapted for application to boats which are not provided with the inward cut and transom. In this instance a substantially U-shaped bracket 36 is provided, the body of the U being bifurcated to be secured over the end boards 36 of the boat by a suitable securing nut 37. The upper ends of the U are notched as at 38 to receive the studs 18 of the motor 17 Thus the motor is adjustably mounted and is tiltable in its mounting and may be retained in tilted position by a conventional modification of the brackets 27 and the arms 31,- or their equivalents. It will be seen in this form of the invention that the structure is adapted to adjustably support in pivotal position various types of conventional inboard motors for use as outboard motors. j

It will also be readily understood that the invention is not confined to the specific structural details herein illustrated but that numerous changes and modification and the full use of equivalents may be resortedto without departing from the spirit and scope of the invention as outlined in the appended claims.

nssrvae I claim:

1. In combination with a motor boat, means for pivotally mounting the motor, said means being adjustable longitudinally of the boat and including recessed plates adapted to receive extending lugs of the motor, said plates having vertical recesses and a plurality of receiving recesses communicating therewith.

2. In combination with a motor boat,
