Referring to the drawings a device is shown comprising a bracket 5. Said bracket comprises laterally spaced portions |50.. Each portion |5a has an inner-part |5b and an outer part |5c. Parts |511 and |5c are joined attheir upper ends and are spaced to forma recess or opening i6 in which the boat transom or end of the boat 'will be disposed. Each portion i522 has a hub or boss |50 at its lower end which is tapped t-o receive a clamping screw 'I equippedwith a head I8 adapted to engage the inner side of the boat transom. The screws are flattened at their outer ends and disposed between the bifurcated ends of a handle member ylil to which they are pivoted by the pivot rivets 20. The inner portion of the parts |5b are curved in vertical cross section as shown in Fig. 2, and are also curved about substantially horizontal radii at their outer sides as shown in Fig. 1. The portions |5a at their lower ends are provided with grooves |5ce in which is disposed aY plate 2| which extends between portions |5a and secures the same together in fixed relation at their lower ends. Plate 2| is secured at each end by a .pairv of countersunk headed screws 22, one of which ex- I tends into a projection |5cc andboth of which extend. into a lug |5cd in the rear of groove |5ce (see Figs. 13 and 15). The upper partsof portions |5a are horizontally bored to receive a connecting or tie bolt 23 as clearly Ashown in Figs'. 1 and 5. Said portions |5a arefprovi-ded with recesses |5d to receive the head and nut respectively of bolt 23.` Disposedbetween por tions |5a is a member 25 bored adjacent its upper inner end to receivebolt 23 and having lateral faces engaging faces |5e at the inner side of the parts |5a. Member 25 has a hub 25a iat its lower end bored to receive' a portion of the outboard motor and has a hub 25h at its upper end which is likewise bored to receivea portion of said motor. The outboard motor is thus swingingly carried on member 25, which ymember is swingable on bolt 23 and about the axis thereof. The lower-portion of bracket 25 moves between the portions' |5c of member |5 as clearly shown in Figs. l and 2. The portions |55 are provided with grooves or slots |53 at their forward adjacent parts and' a plate 26 extends between members |5a, the same being curved on the same curvature as the front of portions |5b, said plate having tongues 26a disposed in the grooves |5f. The lower end of plate 26 extends beyond slots I5f, the same being disposed between the side portions |5c and curved as shown in Fig. 8. It will be noted that tongues 26a do not extend arch or dome shape.

to the bottom of slots I5f. If it is necessary to move the upper ends of portions I5a together or take up wear between said ends and member 25, this can be done by tightening the nut on boit 23. The grooves |5f will thus accommodate this movement. The curvature of the portion of plate 26 between slots |5f and the curvature at the upper ends of portions |5c give a nice streamlined structure and one giving a pleasing and ornamental effect, The forward side of portion |5c as shown in Fig. 2, extends substantially vertically and this will engage the outer side of the boat transom. Small rounded projections |51; may be provided at said side for engaging the boat or transom. The bore or hole |5m which receives bolt 23 is surrounded by a lug or boss |5n. Lugs I 5k are provided on portions lia arranged to be engaged by lugs 25d on member 25 to limit the upward swinging movement of the latter. Each portion |5a is recessed on its inner side to receive a plate 28. Each portion |5a as clearly shown in Figs, 7 and 8 is provided with spaced lugs or bosses |512 in which the recesses |5pa for plates 28 are formed.

The member |511 also has transversely extending ribs |5q and |511 A rib |5s also extends from boss |511, transversely of the bracket, A rib |5t extends from one of the portions I5p to the side of the bracket. As shown in Fig. '1, the member |5a has its inner side |5u substantially in one plane. The upper side oi lug or hub |50 extends in one plane which is substantially perpendicular to said side or plane of member |5a as shown in Fig. 11. The sides of the rib |5q are also substantially perpendicular to said side or plane as shown in Fig. 11. The sides or ribs I 5s, |5r and I 5t are also substantially perpendicular to said side or plane and the sides of boss |511l are also substantially perpendicular to said side or plane. The sides of the ribs or bosses I5p are also substantially perpendicular to said side or plane as shown in Fig, 13. The inner sides or walls of the portions |5b and 5c of the bracket are also substantially perpendicular to said open side and said plane adjacent said open side. This is clearly shown in Figs. 12, 14 and 15. It will be seen that there are a plurality of recesses formed by the walls of portions |5b and |5c and the ribs |5q, |5s, |51, |5t and the bosses |511 and |512. The inner sides or walls of these recesses are substantially perpendicular to the open side of the bracket and said plane or converge somewhat as they move away from said plane. This structure enables the bracket |5a to be made by a die casting process. The cores oi' the die can be withdrawn toward the open side of the bracket. The sides of ribs |5q, |5s, |5r and |5t converge slightly toward the open side of the bracket and the walls of said recesses as shown in Figs, 11 to 15 converge inwardly so that said cores of the die can be conveniently withdrawn and withdrawn unobstructedly. The open side of the bracket is seen in Figs. 8 and 9. The observer is looking into the open side of the bracket in said figures. The bracket is particularly constructed and arranged therefore, to be made by die casting.

It will also be seen that the top wall of portion |5b adjacent the open side of the bracket is formed on a curve of general semi-cylindrical form, As shown in Fig. 1, the outer surface of the bracket is also formed on a substantially semicylindrical curve as seen from the iront or rear. The upper part of the bracket is thus of hollow This forms a very strong 'of plate .28 and pi 3.
