Y Be `it known .that I, SAM-DEL T.,KURTZ, .a

-citizenoif the United States, residingat San iego', in :thelcounty'of San Diego and State 5 fof Oalifornia, 'have 'invented .a .certain new and :useful Gnrapp'lingfApparatus, of which the ollowingisa specification.

Mylinventionl relates to axgrappling ap- Imore particularly adapted vfor luse K lin removing 1articlesfrom .the bottoms ot rivers or bodies of water, `or :trom holes,

paratus,

wells or the like, and-the'nobjects of =my invvention are: First, to provide a grappling apparatus ofthis class in `which the .article or object which it is `attempted vto grapple trips the apparatus V'and causes the apparatusto seize or grab flsaidvarticlc or =ob]ect;

second, to provide an .apparatus `of this class which is spring actuated and in which the..` supporting :means is -soconnected with vthe.

grappling apparatus that the raising of the load causes the grappling apparatustofeny'gage the article raised r:more tightly; third, to -providean apparatus of this class in which the tripping member, as soon las the apparatus is tripped, is thrown out of engagei `ment with thearticle 4and-upwardly out ofO the way.; fourth, .to provide anv apparatus-of this class which may be extended and operated at :a long distance Jfrom the operator; lilith, to provide an Lapparatus .of this class which is applicable for :use in water or. in any yplace that is ordinarily inaccessible; sixth, fto provide anovelly constructed grapipling device, and'seventh, to provide' an apparatus .of this class which is very simple and' economical yof construction, durable, ef-

ficient, automatic in lits action and which will not readily deteriorate or -get Vout of'- lVidednearl its lower end with lugs 13 lto 40 order. I 1

VWith these and fother objects in yiew,.as

will appear hereinafter, my invention consists of certain novel `features of construction, Vcombination fand arrangement :of parts and portions,

I in detail and appended claims, reference accompanying vdrawings and to the characters of reference thereon, which form a part of this applicatiomin which:

The, grappling members vand 2,: ltrip`rI member 13, linksl 4, vsprings- 5, Y main spring a6,

Vcables .7 'and Y8,-and Acable 4guide memberQQ, yconstitute the principal partsand portions ofmy grappling apparatus. The grap. .ling members il and `2 `are preferably made .ot

metal in the form ofa bar. They .are .each

provided Ion .their normally lower endswith inwardly extending'engaging `points l? and 2a..; They are. alsoprovided with flugs f1? and?? .with whichwtheends ofthe links 4 are piyotally connected. They are ,alsogpro- Videdfwith .lugs v 1 fandQc .With which the v one ends of vthe'cablesareconnected.k fllhey are' also lprovidedfwith lugs ldand 21.,1yvith which the opposite entdswof .the springe-are connected, .and they rare .provided intermediate their Vends withy 'large double gbifucated lugs le .and ,2e ,by .meansof which theyare pivotally. connected together by means of a vbolt 10. Thisbolt alsov lsupports the member 9 which is :provided withholes 9b therein adapted Vfor guides for the cables 7 and 8 which pass through saidhole', supported l. by .these cables? .and v8. Recifprocally mounted in the member f9'is the trip member '3 by l means of a hole positioned centrally Vlinjvsaid member 9.v .Thisitrip--member-3 .is .pro-

which are piVota-llyl connected the inner y. j

ends of. the link members 4. AThisA trip 'memyber is valso provided with lugs `binwhich 10, as vshown lbest in Fig. 2 of kthe dr aw'ings.`

rThe .upper .end of 'the` member 35S "bifurcated,

which .is `preferably al'p'late spring,- an'd it and in the'space between the-.bifurcated portion is mounted the main spring 6, f

`is secured'at its opposite ends to the ille-i113,`

bers 1 and 2 by means of the lugs ld and 2d. This member 3 is provided with a pair of ianged lugs 30, the flanges of which are adapted to engage the upper ends of the members l and 2 and form a latch for holding them in close relation at their upper ends and therefore their lower oi' grappling ends spread apart, as shown best in Fig. l of the drawings. This member 3 ishollow and extends upwardly some distance, and in the hollow portion are'positioned the cables -7 and 8 which serve as supports for.' the grappling device. Y* I VThe operation of the grappling apparatus is' as* follows: The apparatus is lowered on thec'ables 7 and 8 so that the lower ends 'la and'2t1 are on'the opposite sides of the object which it is desired to raise andthe extended end of the -tripping Vmember 3 engages the object` and raises the vtripping memberrelatively to themembers l and 2,

which causes the portions 3 to be disen# gagedfrom the upper ends of the members l and 2, whereuponl the spring 6 thrusts the upper ends of said memberslapart and the lower 'endsof said members together. 'At

the same time Vthe spring 5 thrusts the tripping member upwardly so that the grappling members engage the object to be raised at the lower end, as shown best in Fig. 3 ofn the drawings. v y

It will be ynoted that when the object is gripped in this manner, the cables 7 and 8 tend to' draw the lower ends of the members 1 and 2 together because they are connected below the'pivotal mountinglof said members, therefore the lo-ad tends tofdraw the ,Y grappling members together at the lower rangement substantially as v ends against the object to beV raised. 4o

Though I have shown and described a particular construction, combination and ar- A appended claims.

Having thus described my invention, what I claim las new and desire to secure by LettersPatent, is: y I
