CLOSURE FASTENER.

Application filed August 25. 1924. Serial No. 733,882.

This invention pertains to closure fasteners and is more,particularly directed to cured by a spring latch of one character or another, usually consisting of a spring secured rod provided'with a finger hold and a projection or a hook adapted to cooper atively engage an opening eye, projection, or the like, in or on the hood, but none of them provide means to guide the latch into engagement with the hood nor means to support the latch in its disengaged position. Common forms of these hood latches are to be seen on the more popular and cheaper makes of cars and serve their purposes, per- 'haps, in full value. However, the more expensive and durable makes of automobiles demand a more convenient, more secure type of hood latch, and one which will have a pleasingappearance to the eye. Veil appointed and distin features on automobiles, lend color an style to them.

It is one of the primary objects of my invention to provide a strong, positively operating latch which may be made in various styles and designs with but relatively small cost of manufacture. Another object is to devise a latch that will positivel engage the hood and will prevent thehood rom pulling or being jarred loose and from rattling.

A further object is to rovide means to guide the latch into locking position with the hood and means to securely position the latch against displacement when unlocked.

' Further objects will become apparent from the description and claims and from the drawing in which:

Fig; 5 is a side sectional viewof a moditied form of "latch,

Fig. 6 is a sectional view of Figure 5 taken along the line 6-6 thereof,

Fig. 7 is a side elevational view of a still further modification, and,

Fig. 8 is a top plan view of the latch of Figure 7 Referring to Figures 1 to 4, inclusive, I have shown a cylindrical barreled latch 2 having hand or finger holds 4 and 6, although any suitable number may be supplied, a projection or tongue 8 and a fulcrum projection 10, all of which may be formed integrally or in any suitable manner or from any desired material. Within the barrel 2, a spring 12 is engaged about a rod 14;, passing longitudinally within the barrel and abuts between the washer 16 and the inwardly flanged end 18 of the barrel to urge the barrel longitud'nally of the rod 14 and into engagement with the hood or with a latch guide to be hereinafter described. The rod 14 is secured in any suitable manner such as is shown at 20, in Figures 1 and 2, to any rigid portion of the car or car frame. In these figures the rod 14 is shown as engaging a bridge portion 20 formed in the latch guide 22. This guide 22, which may be of substantially U-shaped cross section, is provided with ofi'set portions 24, 26

through which bolts, screws, rivets, or other fastening means may be projected to secure the guide to the frame or other ortion of the machine, one or more depresslons 28 to receive the fulcrum projection 10 when the latch is disengaged from the hood and a rear wall 30 which slopes upwardly and outwardly for a purpose to be hereinafter described. To the hood or engine cover 32, a latch engaging member or bracket 34 is adjustably or otherwise secured by means of bolts, screws. rivets, and the like, 36, and this latch engaging member may be provided with a depressed portion 38 to receive the latch finger 8, as will be readily understood. Slots 40 may be provided in the member 34, or in the hood. if desired, for the purpose of adjusting the member 34 with respect to the latch to .rompensate for manufacturing errors.

From the foregoing, it will be seen that the latch may be lifted upwardly and outwardly against the action of the spring 12 to disengage the projection 8 from the latch engaging member 34, and to engage the fulcrum member 10 over and behind one of the serrations or depressions 28 of the latch guide. This will positively secure the latch out of the way and out of engagement with the hood, so that the hood may be raised or manipulated as desired. When the hood is replaced or dropped down to within a reasonable distance from the frame of the car, the projection 10 of the latch is disengaged from behind the serrations 28 of the guide, and the fulcrum projection 10 riding down the inclined face 30 of the uide under the action of the spring 12, forces the latch inwardly toward the hood, where the projecting finger 8 will engage with the latch engaging means 34 on the hood to carry the hood down and securely lock it against displacement. If the hand holds 4 and 6, interfere with any structure such as the fender of the machine when the latch is lifted out of engagement with the hood in one plane, it may be necessar or desirable to turn the latch 90 in either direction to engage the projection 10 with one of the side depressions '28, and when the latch is secured against its cooperating means on the hood, the combined action of the spring and inclined surface serve to press the latch finger 8 firmly into en agement with the member 34- to prevent the hood from loosening or rattling.

In the views of Figures 5 and 6, a cylindrical or other form of barrel 50 is arranged to be soldered, riveted, or fastened in any suitable manner to the automobile frame 52, and a collar 54 may be disposed thereabout to aid in rigidly connecting the same. Interiorly of the barrel is a spring pressed plunger 56 having at its outer end a finger grip 58 and its inner end bifurcated as at 60 to pivot-ally receive at 61 a tongue or other latch member 62 formed for engagement wit-huthe hood latch cooperating member 34.. The spring 64 abuts between the inturned upper ends of the barrel 50 and a ca-p guide and washer 66 adapted to ride hp and down within the barrel andto engage with the surfaces 68 of the tongue members 62 to force said tongue member through a slot 70 formed 'in the sideof the. barrel and into engagement with the member 34.

The tongue 62 is of substantially the same width as the interior of the barrel 50 so that when it is desired to release the latch from the hood, a pull on the handle 50 willcause a shoulder 72 on the tongue to engage with the end of the slot 70 and turn said tongue about its pivot 61 thus throwing the right hand shoulder 68 against, the cap guide 66 to initially slightly compress the spring, whereupon further movement of the rod 56 upwardly will draw the tongue up within the barrel further compressing t e spring until a notch 74 in the rod 56 engages with the inturned upper end of the barrel. This will lock the latch in released position. As an alternative. I have provided a projection 76 on the interior of the barrel for cooperative engagement with the shoulder 78 on the tongue when said tongue is rotated 90 within the barrel handle 58.

In the views of Figures 7 and 8, the latch comprises two link' members 80 and 82, pivoted together at 84, the link 80 being provided with a projection or finger 86 for cooperative limitin engagement with lugs 88 and 90 oppositey disposed on the link 82. The link 80 is bifurcated to receive the end of the link 82 to which it is pivoted and may be provided with an arcuate face 92 for cooperative engagement with a suitable member 35 on the hood. The link 82 is formed in two portions to straddle the eye of a rod 94 secured to or forming part of spring 96, in turn secured at 97 to a bracket 98 which is rovided with an upright portion 100 hi ureated at 102. The link 82 is pivoted to the bracket portion 100 at 104.- and may be provided with a finger grip 106.

\Vhen it is desired to unfasten the latch, a finger is inserted in the grip 106 and the latch pulled upwardly and outwardly against the action of spring 96. When the links are outward to a point where the pivot 84 is beyond the line of pivots 97 and 104, the spring 96 will draw the pivot 84 downwardly and secure the latch in its unlatched position.

While I have shown and described but three modes in which my invention may be utilized, it will be obvious that it is susceptible of numerous modifications and for that reason 'I desire to be limited only by the spirit and scope of the claims appended.
