Patented Mar. 21, 1944 UNITED STATES FATENT OFFICE HOOD LATCH FOR HORIZONTALLY HINGED HOOD CLOSURES Application April 11, 1941, Serial No. 388,059

My invention relates to an improvement in 10 Claims.

automobile hood latches and has for one purpose the provision of an improved hood latch or latches for an automobile hood closure in which a pair of closure members is hinged along a generally horizontal axis extending along the length of the car.

Another purpose is the provision of closure means which shall be secure and efficient and which will prevent rattling.

Another purpose is the provision of improved. hood latches which may be actuated from within the driver's compartment and which cannot be actuated from outside the drivers compartment.

Another purpose is the provision of such hood latches in which means are provided for preventing actuation of the hood latches by the insertion of tools, screw drivers, or the like, beneath the edge of the hood closure or closures.

Another purpose is the provision of multiple and unitarily operated hood latches, and rattle preventing means therefor, for the so-called hutterfly type hood closures.

Other purposes 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 where- 1n:

Fig. 1 is a side elevation with parts broken away;

Fig. 2 is a plan View;

Fig. 3 is a section on the line 3-3 of Fig. 1;

Fig. 4 is a section on the line 4-4 of Fig. 2, on an enlarged scale;

Fig. 5 is a section on the line 5--5 of Fig.

Fig. 6 is a section on the line 6E of Fig.

Fig. 7 is a section on the line 'I--| of Fig. and

Fig. 8 is a view similar to Fig. 4 on an enlarged scale, illustrating the parts in open position.

Like parts are indicated by like symbols throughout the specification and drawings.-

Referring to the drawings, I generally indicates an automobile hood having a plurality of be welded or otherwise secured to. the hood. ,Upper flanges 1 may be secured to a flange 8 extending inwardly from the top of the hood wall I. V,

The plates 4 have lower flanges.

It will be understood that the members 4 constitute base plates, which may be varied in detail, shape and proportion to suit any particular size or shape of hood, depending upon the car to which the hood latches are applied. it) indi cates a pivot pin passing freely through each plate 4, which may for example be mounted on a plate II, adjustable on each plate The pin is headed, as at I2. Rotatable on the pin It is a bell crank lever I3, one arm of which is secured to an actuating rod I4, as shown for example in Fig. 5.

It will be understood that the rod I4 extends between the two bell crank levers I3. It may have an offset portion or eye I 6, to which is pivoted any suitable actuating rod I1, which may extend to the dash board, where it is provided with a manually operating knob or handle I8. I9 is a bearing mounted on the inner face of the hood wall I, in which the rod 24 is guided. 20 is a tension spring extending from the hearing l9 to the eye I6. This spring tends to hold the rod I4 in forward or closed position. The efiect of a pull on the handle I8 is to move both the bell crank levers to release position.

Each hell crank lever I3 has an upper arm 25, which abuts against a lug 22, on the plate which also has an outwardly extending locking lug 24. The plate 23 is also pivoted on the pin I0 so that a pull of the operating rod I? to the left, referring to the position of the parts in Fig. 4, will, by rotation of the bell crank levers, move each of the plates 23 to the right. This clears the locking lugs 24 from the latches 3B, which are normally upwardly urged by the compression spring 3|. The latch 3b, with its notch 32, which is engaged by the lug 24, is herein shown as unitary with the plate 33, mounted on the 'hood closure 2. The spring 3| is compressed between the upper bend 34 of the latch and the washer 35, mounted in any suitable way on the shank of the latch. The latch 30 passes downwardly through the aperture 9 in the flanges l and 8, and the washer 35 engages the upper flange 8 of the closure wall I so that when the lugs 24 of the plates 23 are moved to the right, referring to the position of the parts in Fig. 4, the springs 3| are effective to raise the closure 2 upwardly a slight distance. Thereafter the closure may be lifted manually to fully open position.

In closing the closure the operator merely thrusts down in such fashion that the nose of the latch 39, which is inclined, as at 38, overrides the edge of the lug 24 and snaps it into closed position. The plates 23 are normally held in looking position, for example, by the tension springs 46, one end of which is secured to an ear 4| on the plate ii, and the other end of which is secured to the arm 52 on the plate 23. In its downward movement the latch 33 is also guided by the inclined oiiset 45 on the plate M. This inclined offset 45 terminates in a vertical portion 46, which abuts against the edge of the latch 30 opposite to the locking lug 24. It will be observed that, when the latch 38 is moved to locking position, it will thereafter cam the plate 23 in a clockwise direction, without, however, rotating the bell crank lever l3. It will be noted that there is no clearance or space through which an instrument can be inserted to move the plate 23 or the lug 24, so that the latch is tamper proof and can be actuated only by drawing inwardly from the interior of the vehicle on the rod ll, by the employment of the handle 58.

It will be observed that the plate H is bodily adjustable and secured in position by the bolts Ha. It is shown as a vertical adjustment, it being realized, of course, that a slight horizontal adjustment may be provided if desired. Since the plate i I carries the guide 65, 46 and the pivot pin iii, the locking means can be bodily and simply adjusted in relation to the keepers 3!).

It will be realized that, whereas I have described and illustrated a practical and operative device, nevertheless many changes may be made in the size, shape, number and disposition of parts without departing from the spirit of my invention. I therefore Wish my description and drawings to be taken as in a broad sense illustrative or diagrammatic, rather than as limiting me to my precise showing.

The use and operation of my invention are as follows:

I provide a simple and efficient latch structure which is adaptable, for example, to automobile hood closures in which a pair of closures is hinged along a generally horizontal longitudinal axis. I provide a hood latch closure which may be locked by simply slamming or urging the 010- sure downwardly to closed position, without affecting the actuating means within the drivers compartment.

I provide a keeper, including the shank Bil, which is in effect unitary with the closure, which may be made as a single piece, including the base portion 33, the upper bend 35, the. shank 30, and the enlargement which receives the washer 35. The shank serves also as a guide for the spring 3i, the washer or thrust member 35 being urged by the spring against the upper flange 8 of the hood when the closure is in closed position. The plate H is vertically adjustable for variations in size and proportion of parts, and also if necessary to take up wear.

The member 2! provides a lost motion which permits the lug 2 5 to rece'de when the portion 38 of the keeper cams over it, without affecting the position of the actuating rods or the manual handle 58 within the vehicle. The latch and keeper assembly can be appliedto the hood and closure without any special design of hood and closure, and are advantageously supported in whole or in part upon the vertically superposed flanges of hood and closure, as will be clear, for example, from Fig. 7.
