' F. D, BozARTH HOOD LOCK Filed April 1o, 1937 l* Patented Feb." 7, 1939 `orrffler.

` .-,A'well known rtype of `motor `car `is fprovided with av. hood, :including ra lid, .mounted to n yswing .upwardly and backwardly. 'In'ffsuch akpconstrucation, .-accessj'is had readily :to thelinside ofzthe hood, *which is :desirable "for :many purposes, 'f but f f. ,is undesirable iin lView .of `other considerations. "'Forfinstance, la batteryiis located in theshood and .itis a common ,y practice .to raise the'lidz and v:steal fthe battery."

` ;In view l'of ,thelforegoing one object of thein vention .fis v`to 'provide a novel mechanism fj'for locking the klid of i the ,hood rin closedjfposition;` it vbeinggpossible 'to ,unlock the lid onlyffrom. vapint within the car. Another objectoffthe 'invention `.i315 :iis to supply :a vlocking mechanism of "the :"kind mentioned `which :can: be installed in fthey standardjform -of :'car, #without working vany changes .inthatliorm.v l

Anotherxobject lof lthe invention is kto vfurnish r120 a locking "mechanism which vcannot readily -rbe .tampered with `by*,anznnauthorized person.

' It isl withinthe province of the disclosure -to :improve generally and 'to enhanceV the .utility vof Ldevijces of that typ'etorwhichthe presentfinven- 25 1 tionxappertains.

"With the above and* other objects in -view, which willappear as th'edescriptionproceeds, vtheinvention vresides in the coxnbinf'itionv and arrangement of parts and ,in the details of Icon- 30 struction fhereinafter'des'cribed and claimed, it

. Abeing understood rthat changes in the preciser emv45 'I'henumeral I marks the body of thehood of azmotorvcar. Atthe forward end ofthe .body l is located a horizontal table 2, provided at itsrear .zend with a `depending ange 3. The hood Viricludes aflid .4, `hingedly mountedat 5,.,to swing '.50v upwardly and ybackwardly. AAt the forward end of the lidill is secured a bottom plates provided atits rearendwith a dependingfiange 1. Intermediate itsends, the bottom/plate has a `depending sleeve8, forming an opening 48 through '66 lthev bottom plate '6.

"'.The numeral .9 :marks an upstanding shoul- :deredkeeper having -,a-,notch or seatv I0 in its rearaedge,-thelkeeperincluding a ,depending stem IlheldbyaLnut i2 onthe table 2 of the body I lo'fzthefhood. LA shaft |14 isijournaledintheupper 5 wallfoixthelid 4::andis supplied with aniexposed ,handlel .Alfoot1l6 isfsecuredfto the lower end f of'theishaft vMandis of disk-like form, the foot iheinggcircular throughout the major portion 'of .itsjperiphery ythe foot, however, beingsupplied 10 with-'a straight `.edge l1. n l'When rthezshait 'I4is rotatedfby means of the handle 1115,*'thezcircular edge portion .of the foot .-lfmaybeiengaged in the'notch I0 of the keeper 19, :asxshown kin Fig. 1, to hold the lid closed.

Whenthestraight*edge Il is brought around to thekeepenthe footili is freed from the keeper 9 .and .theilid 4 may .be opened. Because the shaft l'4 can ,be operated byy meansv of the' handle i5, any oneonthe outside of thecar can open the; iid.

VA lradiator is shown at i8 and hasaforwardly .zextended upper `part :I9 cdening `a horizontal .shoulder @$20. LTheinstrument :board is 1 shown .at

"The parts ,above described :are of standard -constructionv `One object of this invention is to .'providea locking'devicefor` the lid 4, whichfmay be .assembled with the standard construction of a hood and lid, kwithout working changes' therein. '30 Having thatlconsideration in mind, there is provided ,a .bracketincluding a horizontal forward end portion`22'- and a horizontal rear end portion V[23,"connected'by a'depending U-shaped part 24, 'includingzaforward wall `25 and a rear :wall v26. ,35 Therrear lwallll :is not so` high as theforward .wall yand' the rear end portionv23 ofthe vbrack- I=etis disposed a little ,lower than the forward .end Aportion k22. lThe generalfform of the bracketis rectangular. At the rear end of the `part..23 of 40 `the-bracket there is an Vupstanding rectangularly shaped-member `2'! .having a forwardly extended l'arm v2B, karranged Aparallel to the part 23, thearm 128 being.,provided at its forward end with anr upstanding lip `29. 45

In practical operation, so'far as the-mounting vof thev bracketis concerned, the forward end wall 25 ofthebracketis placedagainst the depending flange-3 ofthe table .-2 and the forward end porrtion22 voffthezbraclret abuts against the lower v5() surface of the table '12. The stern Il of the ykeeper :i9 is extended vdownwardly through an opening42in the forward end portion 22 of the ybracket,..and the ynut l2is threaded on the stem I9, tobindtheparts togethenfas shown in Fig. 1. f

y the radiator.

The upstanding member 21 of the bracket abuts against the forward surface of the radiator I8,y below the shoulder in the radiaton The arm 28 of the bracket engages beneath the shoulder 20 of the radiator. The lip 29v on the bracket engages the forward surface of the part |9 of The general construction is such that the rear part of the bracket is interchanged with the vradiator I8 in such a way that the rear end of the bracket is securely mounted,- and cannot be pulled upwardly.

The rear end portion 23 of the bracket has upstanding side walls 30. In front of the lip 29, the box-like casing formed by the parts'23,

21 and 28 is open, but is bridged over by a cover 3| having depending wings 32 secured to the side walls 30. At its forward end, the cover 3| has a depending flange 33, there being an opening 34 in the casing, below the flange 33.

Disposed in parallel relation to the flange 33 is a keeper 35 provided`at tstop with a forwardly projecting flange 36 which overlaps v'the rear end of the Abottom plate 6 of the lid 4. See` curing elements 31 connect the flange 36 with the bottom plate l(i. The keeperv 35 is curved forwardly, as shown at 80y in Fig.'2. There is an opening 38 inthe keeper 35. At its lowrend, the keeper 35 is provided With an upwardly extended and Aforwardly inclined guardA and stop 39.

An elongated bolt housing 40 is located with-V in the casing hereinbefore defined and is secured to the part 23. In the topof thel bolt housing 40 there is an elongated slot 4|. The slot v4| receives an upstanding lug 43 on` av latch bolt 44 mounted for. reciprocation inthe housingy 40; The Abolt vI4 has a beveled forward end 45. A compression `spring 46 is located Iwithin the bolt housing 40 and abuts at its rear end against the rear end of the housing, the vforward end ofthe spring abutting against the rear end of the bolt. A tubular sheath 41 extends backwardly. from the part 21 of the bracket. An actuating member 49,` preferably Aa wire, extends through .the

1 sheath 41, through the rear end wall of the bolt van operating member 5|, preferably a plunger,

provided at its rear end with a handle 52. The plunger 5l slides in a tubular guide53 secured tothe instrument board 2|, the handle 52 being accessible vfrom behind they instrument board.

- The plunger 5| hask a laterally extended finger f latch bolt The operation of the device is simple. When the boltV 44 is in the position shown in Fig. 1, the lid 4 may be closed, and the keeper 35 will engage automatically with the bolt. Thema per-` 5| is relieved, the latch bolt 44 assumes the position of Fig. `1, under the impulse vof the spring 46. It may happen that it is desired to hold the stances, the handle52 of the plunger5| .isgiven a slight turn, and the finger 54'on the plunger 44 retracted. Under such circum- 5| is engaged in the seat 56 of the bayonet slot the lid 4 in' closed position, it being possible to unlock thelid from within thecar, another end accomplished being that the device forming the y subject matter of this application may be assem- Y bled readily with known hood and lid parts, without working any changes in them.v y

- Having thus described the invention, what is claimed is:`

In a locking device for use in connection with an"automobile structure embodying a hoodcomr prising a .body having a rearwardly#extendedV table anda hinged vlid supplied with a bottom piece, the automobile structure embodying a raend portions of the bracket, means for securingv the forward end portion of the bracket to Y,the table, the bracket beingofsuch length that it will engage beneath the said shoulder, the U- shaped part of the bracket being adapted to receive a' keeper secured tothe bottom piece ofthe lid, and a keeper-engaging lockingmemberfunderI the'control of an operator rand movably mounted on the rear portion of the bracket.v
