vIt isi-.title object ofthe invention to obtain Y a construction of hood latch which, with the exception of the operating handle, is con- I eealedwithin the hood. It is a further bject to holdv the hood covertightagainst its frame so as to eliminate ossibility of rattles. Still further it is an ob)ect to obtain a simple and. durable construction as hereinafter set forth. Y l. In the drawings: AFigure 1 is, a yvertical central section through the latch showing the same in position for locking the hood cover;

Figure 2 is a cross section on line 2-4-2 'of I Figure 1;

Figures 3, 4 and 5 are perspective views of various arts `of the construction designated by re erence letters.- Y

A desi nates the hood cover-and closes. On the inner side of the cover A is attached abearing member C for receiv` ing va slidable hook latch member D. The lower or hook end ofthis member D is adapt- A ed-to-engage with. akkeeper Amember E secured to the sill andthe engagin faces D E of these members are soinc ined that drawing upward on'the hook-Will pull the coverA both downward and inward.

`v:so l The member D is referably-struck up of.

sheet metal so as to ave a. hollow shank D2 with a. closed end formed by the-flange D3 bent from the back portion of the shank and l the reinforcing flanges Dbent from the side portions thereof. vTogethertheseA flanges form arigid abutmentfor a sprin FV which is 'housed within the hollow shan There' will be hereinafter explained.

B the 'Y 20 sill or ot 1er part against which the coverv formed by the vflange D3. At the opposite end ofthe member G a portion of the web thereof is struck inward to form a iiange G2, leaving an opening G3. H is anv operating lever which ispivoted at I in the bifurcated upper'end of the member G. `This lever is provided with a hooked nose portion I which in the swinging of the lever forms. a cam for lifting the members D and G as The member C has a plate portion C which is bolted, riveted or otherwise secured f to the cover member A and a rectangular portion C2 which surrounds the member G r. There is also a. flange portion C3 struck i'n- Y ward from the plate portion C over the end of the rectangular portion C2 but of a width limited so as to fit between the furcatons of the member G.` In assembling the parts ,the spring F is first placed within the hol- The member G is then enlow .shank D?.v gaged with said shank so that the ,fiange or tongue ortion G extends within the` hollow of tl e shank D2 and engages the end of the spring F. Also the flange G2 will form an` abutment which limits the movement of the shank member Dunder .the actuation of the spring. Thus byselecting al spring'of proper size it will be tensioned by the. kasfV sembly of the parts just mentioned rvsoy as to yieldably hold the members D and G lfrom l telescopic expansion. vTo engage the 'assernbled membersD. and G withv the bearing: member C the flange Csfis originally left in a position to clear the end of the-member G so as to permit the-'latter to be-slilfl through the bearing. TheV flange C3 is then bent downward tolextendthrough the aperture i Grs inthe member .G andtofrestfu-pon the; end of the rectangular'bearing portion C2. Theflange C3 is also formed with a depression or notch C4 for engaging the end of the nose .,I. v -Y .In use, when` the bearingl memberv C is properly lsecured to the cover member A, the handle or lever H will project through lan aperture A in said cover member `so as to be on'the outside thereof while the restof the assembly is'on the inside. When lthe parts are in the position indicated in dotted lines,

Figure 1, the hook D will be 'in a position for latehing engagement with the keeper E when the coverA is closed. The lever ll then can be depressed into the position shown in full lines, Figure l, which will cause the nose or cam portion I to slide over the flange C3, thereby lifting the member and sliding the same in its bearing .2. .l'he movement of the member G will be eonnnunieated through Vthe spring l to the member l) which will also be lifted, but on account of the engagement of the hook 1) with the keeper l the upward movement. of the member l.) is limited. Further upward movenient of the member will then compress the spring l", the tension olE which will draw the inclined face D ol' the hook dpposite the. engaging inclined face lil oi' the keeper ll therehvuot only drawing the cover A downward but also inward into tirm contact with itsI supporting trame. 'l`he movement of the handle-ll is sullieient to earr the nose portion vl beyond thi-center oiI its pivot l and into engagement with the notch (l'l ill the member t into which position the handle. will be locked 'from accidental disengagement.

'l`he construction above. describe-d is one which can he cheaply manufactured, as the various parts can be struck up from sheet metal. assembled, is t'ree from loosel or rattling parts and which. when in locking position, iirmly holds the hood coverfrom rattling.

What we elaimas our invention is:

1. A hoodlateh comprising a hook mems lber having a hollow shank. a member telescopieally engaging said shank, a spring within said hollow shank engaging .abutments on the same and said telescopic member to 'vieldably resist. relativev extension of said members` a bearing in which the telescopically engaged members are slidably mounted on the inside of the hood cover. a keeper :for engaging the hook, a lever pivotally eonneeted'to said telescopic extension and projecting through an aperture in the hood cover to the. outside thereof, and a cam portion on said lever for engaging saidlbearing whereby the operation of the lever will lift said telescopic extension and place a tension on the hook for drawing the same into its keeper.

2. A hood latch comprising a hook member having a hollow shank closed at its end and open on one side, a spring member in said hollow shank, a member ot' U-shaped cross section telescopicallyy engaging said hollow shank 'and having a tlax'igmpro-jeeting inward therein to engage one end of said sprine', the opposite en-d of which abuts against said closed end, a bearing secured to the inner side of the hood cover in which said `telescopically engaged members are, slidably mount-- ed, a keeper for engaging the hook` a lever pivotally connected to said U-shaped member lt is also a construction which.` when yand extending outward through an aperture in the hood cover, a cam portion on said leve and a portion on said bearing for engaging said cam whereby the operation of said lever will lift said telescopically engaged member and yieldably draw said hook into engagement with its keeper.

3. A hood latch comprising a hook member struck up from sheet metal and formed with a hollow shank closed at one end and open on one side, a spring within said hollow shank abutting against said closed end, a ymember of U-shaped cross section telescopicall)v engaging said shank and having an inwardly projecting flange for engaging the oplmsite end ot said spring, a bearing member mounted on the inner side ot the hood cover in which said telescopically engaged members are slidably secured, said bearing member being provided with al portion projecting inwardly over the end ofthe shank otl said hook membe' and through an aperture in the web ot' said U-shaped member, a keeper for engaging said hook member. a lever pivoted between the furcations ot' said U-shaped member and extending outward through an aperture in said hood cover, and a cam portion on said lever for engaging the inwardl)v 'projecting portion of said bearing whereby the manipulation of said lever will raise said U-shaped member andthrough the spring will yieldably draw said hook member into engagement with its keeper.

4. A hood latch comprising a hook member having a hollow shank close-d at its end and open on one side, a member ot' U-shaped cross section telescopically engaging said hollow shank and provided with a tongue eX- tending'inward into the hollow of the shank, a. spring within said hollow shank Vbetween said tongue and the closed end of the shank, a bearing member in which said telescopically engaged members are slidable, said bearing member having a tongue portion projecting inward over the end of said shank between the furcations of said U-shaped member, and a lever pivoted to said U-shaped member and having a-cam portion for engaging the inwardly projecting tongue portion of said bearing whereby the, movement of said lever will litt said U-shaped portion in said bearing.
