MELVIN G. BAKER, OF CHICAGO, ILLINOIS, ASSIGNOR TO CHICAGO FO-RQrINGgr & MANU- FACTURING COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS vHOOD LATCH Application ledeNovember 7, l1927. Serial No. 231,478.

My invention relates to a latching device and particularly to a device intended for use as an automobile hood latch. One object of the invention is to provide a hood latch,which, while serving to hold the hood down and closed, will Valso force the hood inwardly against its abutment and will thus hold it against rattling. Another object is the provision of a latch of the type above mentioned, which will be cheap and easy to manufacture, simple and durable in construction and streng and sturdy in use.

Other objects will appear from time to time in the course of the specification and claims.

I illustrate my .invention more or less diagram-matically in the accompanying ,drawings, wherein 4Figure l is a vertical section through `an automobile hood-showing my hood latch .in locking position;

Lilie part-s are indicated by like symbols throughout the specilication and drawings.

A is a. portion of an automobile frame, to which may be secured an upstandingrib or abutment member A1, against which abuts the lower edge B1 ot the hood B when the hood is closed. Fastened to the hood B is a member generally designated as B2, which includes a downwardly and outwardly inclined cam portion B3, upwardly and outwardly inclined prongs BAk separated, lfor example,

spherical flange surrrounding the laperture f C8, through which passes the pin C.

The latch body proper consists of the cylindrical member D, herein shown as rolledirom aeSngle blank and with -the single axial-seam D1. `Th e bottom of the cylindermay be formed in any suitable manner to retain the abutment'below described. I Yillustrate the cylndras' being inwardly ,crimped awt D3 to securethe Washer D4 willi ch is loose on the shaft'lC. 'isa washersecured to the-upper end of the pin C and l)G indicates a coil S ring -emnsesed .between the :two washers'.

The intermediate portion Gtis lprovided with :a .downwardly ,projecting .cylindrical .flange G? centrally apertured as at 2G to, reeeive theupper ,end ofthe tube. D. Prior the portion G5 is provided with outwardly projecting lugs or extensions of material overlying or aligned with the apertures E El. In assembling the latch any suitable arbor G7 may be introduced within the tube and, when the handle member G is in position the lugs or extensions G5 are' placed between squeezing jaws G7 and are subjected to pressure suiicient to flow the metal of the handle into the opposed indentations or apertures of the tube. The result is a peculiarly complete and permanent attachment of handle toitube, the connection being only severable by the destruction of the handle member or the collapse of the tube. The collapse of the tube is particularly diiicult, and in practice is not likely to take place, since the end of the tube is both protected and -reinforced by the sturdy surrounding portion G5 of the handle. G1o indicates any suitable lugs or lug member opposed to the cam B2 on the hood. Y

In the operation of the latch it will be understood that when the T lug is between the m-embers B4 in the notch B5, the outward movement ofthe latch away from the hood is prevented. As the spring D5 draws the cylinder D downwardly along the pin C the lugs G10 are opposed to the cam B2 and .to thev downward locking movement of the latch is added the resultant lateral thrust against the hood.

In Figure 11 I have shown the cylinder D having the indentation H, instead of slots.

In particular it willbe realizedthat where in the claims I employ the term aperture I wish to be understood as meaning not merely an aperture completely through the tube, but any indentation or olf-setting of the tube or the tube surface which will provide an equivalent spacey into which the metal of the vhandle may flow.

` lVhereas I haveillustrated means for forcing cold metal into the indentations or apertures of the member D it will be realized that I may obtain an equivalent result by vpositioning the tube B in a mold `and pouring hot metal about it, thereby causing the metal toflow into the apertures and thus to form a permanent engagement with the tube equivalent to that formedH byr the flowing of cold metalinto the tube.V i

IVhereas I have describedand shown invention as employed in the application of a handle to the tube or stem of a hood latch, it

per end of said tubular body and overlying sheet metal stock, an aoerture in the upper i end of said body, a hanc le member surrounding the upper end of said body and overlying said aperture, the metal of said handle member penetrating said aperture, the metal of said handle member being of substantially greater thickness than the latch body.

l e. In a hood latch, a hollow cylindrical latch body having an aperture in the upper portion of the cylindrical side thereof, a handle member overlying the top of said cylinder and an extension thereof. depending about and surrounding the upper end of the tubular bodyand overlying said aperture, the metal of said extension of the handle memberv penetrating said aperture.

5. In a hood latch, a hollow cylindrical latch body having a plurality of apertures in the upper portion of the cylindrical side thereof, a handle member overlying the top of said cylinder and an extension thereof depending about and surrounding the upper end of the tubular body and overlying said apertures, the metal of said extension of the handle member penetrating said apertures.

6. In a hood latch, a hollow cylindrical latch body having a plurality of diametrically opposed apertures in the upper portion of the cylindrical side thereof, a handle mem-v ber overlying the top of said cylinder and an extension thereof depending about and sui'- rounding the upper end of the tubular body and overlying said apertures, the metal of said extension of the handle member penetrating saidk apertures.
