The keeper 16 is disposed adjacentthe, forward "end of theraised 'portion 20 of the plate 13 I as'show'ri jin" Fig. 2. The plate 13 is providedwitha longitudinal slot 22 rearwardly of thekeeper and laterally' offset. with respect thereto, the rear endof the] slot 22 being adjacent the flange 23 (Fig. 4) directed downwardly fromthe jraised part 20 of, the plate 13.1} The slot 2 2 (See'Fig. v2) is partially surrounded by-the raised portion of the plate 13 and receives a safety hook 24, which in the position of the latch parts shownin. Fig. 10, engages theflang e.23 to prevent further opens ing movement of the hood liduntil the operating mem 4 her 17 is moved to the position of-Fig. 8.

Fig. 13 is a detail view of the operating member, the

member being shown in side elevation.

In the drawings, the lower or fixed part of the hood is indicated at 10, and the upwardly swingable lid there for. is indicated at 11. A fixed substantially horizontally The: operating member or actuating lever ,17, best shown'in Figs, 12 and 13, is an elongated stamping of, channeled crosssection throughout the greater part of the 5 length thereof, having a transversely. extending-plate por-.. tion 25at one .end thereof whichmay be grasped by the fingers when the latch'is to be released. The safety hool;

24 is formed integrally with the operating member 17 and is suspended therefrom at one side and adjacent the other end of the member 17. The safety hook 24 is formed as an extension of one of the side flanges 26 of the member 17. The disposition and shape of the hook 24 .is best illustrated in Figs. 12 and 13. v k

' Adjacent the last-mentioned end of the operating member 17, the side flanges 26 are provided withlongitudinal slots 27 registering with one another and receiving a pivot pin 28 which mounts the operating member 17 on the upper plate 14. As shown in Figs. 4 and 11, for example, the pivot pin 28 extends through and ,is fixed to the side walls of the U-shaped plate portion only a short distance rearwardly of the slot 18, the pin 28 being disposed adjacent the upper part of the plate 14.

The operating member 17 extends forwardly to a point adjacent the forward margin of the hood lid, as shown in Fig. 1, and the member 17 is provided with a slot'30 through which the pilot or keeper 16 may extend. A substantially vertically disposed helical compression spring 31 is provided to urge the member 17 downwardly, the spring 31 embracing and being supported by a rod member 32 extending upwardly through the bottom of the plate portion 15 forwardly of the slot 18 and closely adjacent the front end of the plate portion 15 The rod member 32 is provided with an enlargement 33 at the lower end thereof to bear against the bottom of the plate portion 15 at the underside thereof and the upper end of the rod member 32 is enlarged as at 34 to overlie the upper end of the spring 31. The operating member 17 is provided with an upwardly directed protuberant portion 35 disposed forwardly of the keeper 16 and approximately midway between the pivot 28 and the forward end of the member 17. The protuberant portion 35 is slotted longitudinally of the member 17 so that the 'rod member 32 may extend therethrough and a washer 36, interposed between the lower end of the compression spring 31 and the protuberant portion 35, exerts a constant downward and rearward pressure on the forward end portion of the operating member.

As shown in Fig. 13, for example, the upper rear end portion 38 of the operating member is substantially horizontally disposed and in parallelism with the slots .27 formed in the flanges 26. At a point substantially coinciding with the plane of the rear wall of the slot 30 and forwardly and adjacent the forward ends of the slots.27, 1

the portion 39 of the member 17 is bent downwardly at an angle of approximately 15 to the horizontal. The transverse plate portion of the member 17 is disposed at the forward end of the portion 39 and is inclined downwardly therefrom to a small extent. As shown in Fig. 13, the portion 39 of the operating member is'bowed upwardly to a small extent.

The trailing edge of the pilot or keeper 16 is toothed throughout the intermediate portion thereof, .as at 40. In the preferred form of the latch mechanism, twenty teeth per inch are portion of the keeper tooth is preferably 90. mesh with ratchet teeth provided on the operating members 17 and indicated at 41. The teeth 41 are formed in a strap 42 extending lengthwise of the member 17 and welded to the portion 38 of the member 17. The strap 42 has a forward end of hook shape having a portion 42 thereof overlying the rear wall of the slot and having a portion 42 underlying the portion.38 of the member 17, as shown in Fig. 6, for example. The ratchet teeth 41 are formed in the portion 42 of the strap which is best shown in Fig. 7.

From the foregoing, it will be understood that the pivot pin 28 mounts the operating member 17 for swinging movement in a vertical plane extending lengthwise of the hood, the connection of the member 17 with the pin 28 16. The included angle of .each

being 'such that the member17 is permitted limited .slid

ingmovement in a direction lengthwise of the hood. In

the latched position of the operating member 17 shown in Fig. 5, the slots 27 formed in the member 17 and receiving the pivot pin 28, are substantially horizontally disposed and the strap part 42 of the member 17 is also substantially horizontally disposed and is engaged with the keeper 16. In this position of the latch parts, the ratchet teeth 41 provided on the member 17 mesh with the teeth provided on the keeper 16, the cooperating faces of the teeth being inclined at approximately to the vertical. In the engaged or latched position of the operating member 17, the forward end of the member 17 is strongly urged downwardly by the spring 31, and the forward wall 44 of the slot 30 provided in the member 17 is strongly engaged with the leading edge of the keeper 16. It will be noted that the forward wall 44 of the slot 30 is disposed in an upwardly extending plane which is inclined with respect to the plane of the strap portion 42 overlying the rear wall of the slot, as shown in Fig. 5, for example. In the position of the member 17 shown in this view, the forward wall 44 of the slot- 30 is inclined with respect to the leading edge of the keeper 16 and the lower edge portion of the wall 44 is engaged with the keeper 16. Hence, it will be underis strongly resistant to both vertical and horizontal vi-' provided throughout said intermediate The teeth 40 on the keeper 16 stood that when the operating member 17 and the keeper are positioned relatively to one another as shown in Fig. 5, movement of the member 17 in a direction lengthwise of the hood relatively to the upper mounting plate 14 is prevented and the hood lid is tightly latched. It willalso be understood that the toothed operating member 17 may have latching engagement with any part of the longitudinally extending toothed portion of the keeper 16. Furthermore, it will be apparent that the latch mechanism bratory forces in the upper and lower hood elements. The last-mentioned feature of the latch mechanism is partially due to the disposition of the keeper-engaging part 42 intermediate the keeper 16 and the pivot 28 and adjacentthe latter. Furthermore, the teeth provided on the part 42 of the member 17 and meshing with the teeth of the keeper 16 further inhibit any tendency of the latch mechanism to creep open when the latter is subjected to vibration. In this connection, .it is important to note that when sufiicient upward force on the forward end of the spring-pressed operating member 17 is exerted to move the member 17 in the releasing direction and to the position thereof shown in Fig. 6, the toothed part 42 of the member 17 pulls the keeper 16 relatively upwardly through the member 17 to thereby effect a downward pull on the hood lid. Thus it will be underthe spring 31 to the extent that the portion 39 of the operating member is swung upwardly approximately 9-. When and as the member mentioned position from the latched position thereof, the wall of the operating member is swung outwardly and forwardly from the leading edge of the keeper 16 and the slots 27 receiving the pivot pin 28 tip to a somewhat more inclined position than the position shown in Fig. 6, thereby permitting the member 17 to clear the teeth of the keeper 16. form of the invention, a rearward sliding movement of the member 17 of only .025 inch or thereabouts, maybe suflicient to clear the teeth of the keeper 16. Further upward swinging movement of the portion 39 of the operating member to the substantially horizontal position of-Fig. 8, a movement of approximately 6 from the drawal of the safety hook 24 from beneath the flange '23 17 is moved toward the lastto slide rearwardly In the illustrated g to a position (see Fig. 8)" in which clearance for the hook 24 is provided so thatthe hood lid may be fully opened.

' The latch mechanism illustrated in the drawings isof the self-latching type. Upon downward swinging movement of the hood lid from the fully open position thereof, the inclined trailing edge 45 of the safety hook strikes the flange 23 of the lower mounting plate 13 and is cammed forwardly by the latter so that the hook 24 may enter the slot 22 in the plate 13. The forward camming movement of the hook 24 effects upward swinging movement of the forward end of the operating member 17 to facilitate entrance of the pilot or keeper 16 through the keeper-receiving slot 30 formed in the operating member. It will be understood that the tapered upper end of the keeper 16 may engage the member 17 to cam the forward end thereof upwardly as the lid is closed, and further facilitate entrance of the keeper 16 through the slot 30 of the member 17. It will also be understood that the lost-motion connection of the operating member longitudinally of the hood as the hood lid is moved to the closed position thereof. As the lid is moved to the closed position, the teeth of the keeper 16 engage the teeth of the operating member 17 and have a camming effect thereon to raise the forward end of the member 17 so that the member 17 may move rearwardly to the extent that teeth of the member 17 may slide by teeth of the keeper 16 until further downward movement of the lid is prevented by engagement of the latter with the' fixed part of the hood. As the teeth provided on the keeper 16 preferably number twenty to the inch or thereabouts, the lid may be latched in a position in which the lid is drawn clown tightly on the fixed part of the hood;

In accordance with the foregoing disclosure, there is provided a hood latch comprising a pilot or keeper and a latching lever having a snubbing effect on the keeper. However, unlike many, if not all, latches of the snubbing type heretofore employed for fastening hood lids, the latch lever of the mechanism illustrated in the drawings having a keeper-receiving aperture intermediate the ends thereof, is provided with a part disposed intermediate the keeper and the pivot mounting the lever and having open the latch are strongly resisted. Another advantage of the latch mechanism resides in the provision of fine teeth on the latch lever cooperating with teeth provided on the keeper to further inhibit creeping of the latch parts to the open position of the same when the latch mechanism is subjected to vibration.

.Still another advantage of the latch compactness of the same. It occupies little space within the hood of a vehicle. Another advantage resides in the provision of a safety hook, actuating lever, and operating handle incorporated in a single stamping employed in the latch mechanism andbiased by a single spring.

While a single embodiment of the invention has been described and illustrated in the drawings, it will be understood that various modifications and changes in details may be made in the latch mechanism without departing from the principles of the invention and the scope of the claims.
