VDuring storage of outboard motorsv in boat houses, lthelmotors are often 11.191.114teld.4 upon supporting structures Aa'dapte'd to maintain the motors Yin upright position and out of contact with the loor. While in storage, the motors are often used by unauthorized people and without the owner ever learning of such use.
This invention further contemplates the pro- Vision vof a locking device comprising a pair of locking members formed with chambers to snugly receive and engage the wingheads of mounting screws, the locking members being telescopically adjustable for use o-n motors having different' spacings between the mounting screws. The locking members are secured in locked position by a suitable padlock.
This invention embodies other novel features, details of construction and arrangementY of parts which are hereinafter set forth in the specication and claims and illustrated in the accompanying drawing wherein:
Fig. 1 is a side elevational view showing an outboard motor mounted upon the back of a vboat and with the locking device positioned upon the motor mounting screws.
Fig. 2 is a plan View showing the locking device, the motor mounting screws and padlock being shown in dotted outline.

During storage of outboard motors in boat houses, th-e motors 3| are usually supported in upright position, as illustrated in Fig. 1, upon a suitable frame structure (not shown). In order to prevent unauthorized use or theft of outboard motors while same are left unattended upon boats or within boat houses. a locking device of the type thus shown and described may readily be mounted upon the winghead portions 29 of the mounting screws 28 in the manner illustrated in the drawings. After the wing-shaped head portions 29 of the mountfing screws 28 are positioned within the compartments I3 and I4 of the locking members 6 and 1, respectively, the shackle 23 of a padlock 24 is adapted to be inserted through registering apertures 2| and 22 of the tongues I6 and II, respectively. When the locking members 6 and 1 are secured together by means ofthe padlock 24, it will be observed that the mounting screws 28 cannot be rotated to permit removal of the outboard motor 3l from the back of a boat or from a similar type of motor supporting structure provided within a boat house. It has been found that the locking device is also useful in preventtqmeuetins Ascrews ing loosening of the mounting screws 28 due to vibration of the motor during its operation. .By providing means for telescopically engaging the locking members E and 1, it will be noted that the locking device may readily be mounted in locking position by merely moving the locking members toward each other to receive and snugly enclose the winghead portions 29 of the` mounting screws 28 within the compartments i3 and I4. It will further be noted that the members 6 and 'I are telescopically adjustable to permit use of the device with sets of mountin screws of different spacings.
While this invention has been shown in but one form, it is obvious to thoseV skilled in the art.
that it is not so limited but is susceptible of various changes and modications' without de-` parting from the spirit and scope of the claimedA invention.
'I claim as my invention: f
1. In a locking device for securing a pair of outboard motor mounting screws in predetermined position,Y a pair of locking members, each locking member being provided with a housing portion to snugly receive and engagel the head of its respective mounting screw against rotational movement relative thereto, and means for lockingvsaidV locking members together toA prevent disengagement of said members from their respective mounting screws, said locking members being telescopically engaged and movable eil) ment of'said members from their respective mountingscrews, one of said Ylockingm-embers being provided with a tongue, and the other of said locking members being provided with means 4 forming a socket to telescopically receive and engage said tongue.
3. In a locking device for securing a pair of outboard motor mounting screws in predetermined position, a pair of locking members, each locking member being provided with a housing portion having its inner end open to snugly receive and engage against relative rotational movement the head of ,itsV respective mounting screw when the locking members are moved toward each other, and means for locking said locking members together to prevent disengagement of said members from their respective mounting screws, one of said locking members being provided with a tongue, and the other of said locking members being provided with guide means defining opposed grooves to telescopically receive and engage said tongue.
4. In a locking device for securing a pair of outboard motor mounting screws in predetermined position, a pair of locking members, each locking member being provided with a housing portion having its inner end opento snugly re,- ceive and engage' against.V4 relative rotational movement the head `of its respective mounting screw when the locking members are moved to.- ward each other, one of said locking members being provided with Va plain tongue, the other of said locking members being formed with a flanged tongue tofprovide oppositely disposed grooves to telescopically receive andvengage said plain tongue, said plain Itongue and anged tongu-e being formed with registering apertures to receive a padlock. g (l 1' GUSTAVE HARDERVBINZ.
