hoe l5 can be swung outwardly to operative position extending longitudinally from the member 10,Y which forms a handle therefor, to the positionv as indicated by dotted lines ,in Fig;

The handle groove 10c carries aventing rod y16 "mounted on afpin 16a at the outer end,

of the groove 10c, in the manner vdescribed `with respect to the scoop 14.y In inoperative position the rod 16 extends longitudinally along and against the handle 10, and is swingable outwardly on pins 16a to operative position extending longitudinally from the bodyl portion 10-which forms ahandletherefor.V In each instance the tools 14, 15', and 16 at .their Youter` ends engage and bear upon theV springs 12, respectively-which springs maintainthe tools'in their foldedorinoperal tive, and in their outwardly swung operative 1 Y A combined Y which extends thereacross (see Figs. 2 and 3) The -pin y18 isy slidably confined inthe handle position. l y screwdriver andrdraw pin 17 having Iits/body portion square'` lor rectangular in cross section', is slidably mounted andV confinedl in the longitudinal or axial bore 11 of the handle member 10.

and-the bore117cl being disposedyintermediate thefaforesaid'b'ores. These bores 17e-,17d ande are adaptedforfselectiveregistration ,with Vthe sliding pin 18 in order to position the tool 17 in itsinoperative position, its position'functioningas a-screw drive-r,`1or its positioning functioning as a draw pin.` l YFor example, in F ig. 3 the tool 17 is shown in position with the end 17 6 thereof extended from the handleV 10 and the pin 1'8 extending through bore 17o of the tool toholdthe same in its extended position to provide the draw pin 17 6 with the body portion 10 providing an operating handle therefor. Thetool 17 in itsinoperativepositionis withdrawn into the handle 10" until the intermediate bore 17d registers with pin 18, which pin extends therethrough and releasably 'secures the tool in its inoperative position. Tov function as a screw driver, the tool 17 is extended from the opposite endof handle 10 with the pin 18 registered with andextending through' bore 117e. The pin-18.isoperated to'withdraw the same from theboresof tool 17, by swinging the hoe'` 15 outwardlyfromaerossrecess 186 'y i in thehandle, whereupon the head 18a of the pin is grasped: andthe pin slid orwithdrawn l outwardly :from positionacross passage 11.

The tool'17 isthenk moved through passage 1-1 untilthe-:desiredbore ofthis tool isin vregistry .with the pin, which iis then pushed inwardlythrough the bore andfholding: the tool inthe desired adjusted position. Y

u The scoop 14 provides an efficient and vuseful tool or instrument fo-r handling sand, as

does thehoe or L-sha Jed tool 15, while the venting rod16 provides an implementwhieh can be pushed downwardly vthrough thesand andagainstthe pattern to forma small passages forthe releaseand discharge of. gas
