R w 2 o mn. mun \1 T. a L W M E m l n of the Wall 35, including the thickness of wall 36 will permit the cover to be received within the casing, as shown in Fig 2. The length of the back wall is such that its edges 4I and 42 lie closely adjacent the inner edge of the bottom Wall bounding the slots 29 and 3l, see Fig. 2. When Ythe cover is conned within the casing the members 31 and 38 close entrance within slots 28 and 38, the ends 43 and 44 of said members 31 and 38 extending above the top surface of member 36 so as to receive therebetween thetop wall I5 of the casing. The ends 45 and 46, of said members 31 and 38 respectively, rest upon theishoulder portions 340i the curved ends IGI-sand.4 I1 respectively. The screw 21 of the lock 23 may then be turned by the key '1ftoca'user co 1' threaded bore 40, and thusdraw the cover 1I I claim:

1. In a device for locking wing type clamp screws for an outboard motor against movement when said clamp screws engage the stern of a boat, comprising a easing provided with spaced apart aligned grooves adapted to receive the wings of said clamp screws therebetween, and a cover for said casing adapted to rest between said clamp screws for conning the wings within the slots of "said'casin' 'aidlockin'gfmeans for securing the cover to the casing. f

2. A device for locking a pair of spaced wing 'ftype clamp screws for an outboard motor, including a casing having a front wall, top, bottom and end walls, said top and bottom walls providedwithtpairs of aligned transverse slots, said ...wing clamp.screws lspanning and being received irr'said slots; a cover for the casing adapted to into engagement with the casing I2, asl illus-.l

trated in Fig. 3. The key may then be removed.

= The operation, uses and advantages of the -invention just described are as follows:

- In the present form of the invention a definite distance between the clamp screws is conteme plated. This distance is uniform for certain types of motors. After both clamp screwsVV have been rotated within the threaded opening'yoi the stern bracket 3 to tighten the clamp screwsagainst the stern 5 of the boat, the wings of each clamp screw are turned so as to :be substantiallyin parallel vertical relationship. The `wings are. positioned so as to span and lie within the parallel slots of the casing, that is, the aligned slots 28 and 29 in one instance, 30 and 3I in the yseooz;1d .-in stance, as shown in Fig. 2. The cover member I I is then placed upon the shank portions ofrlthe clamp screws, said Shanks being conned within the curved portions 41 and 48; these curved portions are bounded by the curved inner edges of members 31 and 38, and the ends 4I and 420i the back 35. When the key .is within the lock and turned, the screw 21 is rotated, which screw upon engagement with the threaded bore 4U in the stud 39 draws the cover into tight engagement with the casing. The top member 36 of the cover lies within the casing adjacent the 'inner surface of top wall I5, see Fig. 2. The membrs 31 and 38 so cooperate with the casing', and'parfticularly the shoulders 34, as to prevent relative tipping movement between the cover and the casing. Y,

I may in certain embodiments of the invention slot the curved ends I6 and I1 in a manners imilar to the slots 29 and `SI, as for instance l i1-lustrated by 49. in Fig. 6, whereby onebf they/ing ends of the, clamp screws may beconned in said slot, the other iwing end lying, ,withinthe confines of the casing. In suchlan instance@ `would not of necessity provide the winlgreceiving slots in the top and bottom walls of theA casing.. In such a construction difficulty would be fexjperienced by any unauthorized person incon- ,tacting the wings for the purposeof rotatingj'the clamp screws. This construction would permit use of clamp screws having unequal length wings,

and would likewise accommodate varyingly spaced 1 clamp screws carried by a stern bracket,v as is self-evident.
