LATCH FOR HEADLIGHTS AND THE LIKE Filed Nov. '7, 1927 Patented Au 5, 1930 b ES W. DARE, OF CHICAGO, ILLINOIS, ASSIGNOR T THE PYLE-NATIONAL COM- PANY, OF CHICAGQILLINOIS, A CQBJPORATION OE hl'EW JERSEY Larisa non. nnanmamrs Arm THE Ema application filed November 7', 1927. Serial. Fe. 231,586.

My invention relates to improvements in latches for headlights and the like and has for one object to provide a new and improved form of latch or closure which will look-the I headlight door so as to make a tight snugject is to provide a latch which has a kick out or opening eflect. Other objects will appear from time to time throughout the specification and claims.

My invention is illustrated more or less diagrammatically in the accompanying drawings, wherein-- Figure 1 is-a detail side elevation showing the latch in the closed position;

Figure 2 is a front vlew; Figure 3 is a plan view; Figure 4: is a side elevation showing the latch in the open position with the door about to raise the latch to ermit engagement;

Figure 5 is a si e elevation showing the latch about to open the door;

Figure 6 1s a perspective view of the adj usting sleeve Fi ure 7 is a detail perspective of a modified orm of latch.

A is a housing, A a door suitably pivoted on the housing in any suitable manner not here shown. It will be noted that the housin and the door make a snug fit one with the ot er. A is a bracket mounted on the housing. It has an arm Aextending forwardly lug A to assist in positioning the door with respect to the housing. A

B is the latch. It has a hub B rotatable on the pin A held in place thereon by a washer B and castellated nut B with cotter pin B.

46 Extending forwardly from the sleeve B is the hook element B having a generally cylindrical pin engaging surface B, an outwardly inclined cramping surface B" and. an upwardly inclined handle B. B is a kick out foot projecting downwardly from the sleeve VB and adapted when the parts are in the position shown in Figure 5 to engage the front face of the lug A to open the door.

Cis a latch pin on the cover; C is an eccentric adjustable latch sleeve rotatable on the pin C. This latch sleeve has a plurality of spaced apertures C therein. C is a locking screw which may pass through diametrically opposed apertures C and through an aperture in the pin C to hold the eccentric sleeve rigidly in adjusted position on the pin C, the screw being on the lower side or the side where the head will not come incontact with the latch. It will be noted from the arrangement shown in Figure 4 that as the doorcloses with the latch in its closed position the latch handle will be engaged by the in so that the door will tend to open the latc camming the latch up as shown 1n Figure 4 until the surface B comes into engagfment with the eccentric adusting sleeve w en the operator ma rotate tge handle downwardly and cam t e door s ut.

It will beunderstood'of course that while I have shown my latch as applied to a headlight or lantern door, the latch may be equally aswell applied to any door where it is possible for the door to close in a direction parallel with the latch and where it is possible to have the latch and holding pin project laterally beyond the edge of the door and it will also be understood that this latch might be used for any type of closure such as boxes and the like and while I have shown the eccentric adjustment as associated with the holding pin and not with the latch it will be ObVlOllS that any arrangement of parts whereb the efi'ective distance between the ivote screw and that part of the pin where it engages may be adjusted, will accomplish the pur ose as is accomplished in the preferred orm shown. Such an arrangement might take the form of an eccentric bearing for the hook quite as well as the eccentric bearing for. the sleeve.

F is a stop associated with the latch pivot and F is a limit member on the latch ada ted to engagethe stop to limit the motion 0' the latch downward through the locking position whereby the latch can never fall appre' ciably below the position shown in Figure 1 so as to insure that movement of the door toward the latch will always find the latch in such position that it can be cammed open for engagement by I claim:

1. In combination with a latch for doors and the like, a holding member adapted to be engaged by the latch and means for adjusting the distance between the latch engaging portion of the holding member and the latch support, said means comprising a pin, an eccentric sleeve rotatable thereon, means for locking the sleeve in adjusted position.

2. The combination with two movable elements of means 'for locking them together comprising a latch pivoted on one and a holding member carried by the other, means carried by the latch for engaging the holding member and locking the two elements together, a plurality of cams carried by the latch, one of them adapted when thelatch is rotated away from the locking position to force the two elements apart, another adapted when the latch is rotated toward the locking position to draw the two elements together, a third adapted when the two elements move toward one another to raise the iatch to permit it to engage the holding memer.

3. The combination with two movable elements of means for locking them together comprising a latch pivoted on one and a holding member carried by the other, stops associated with the latch to-limit its motion toward and from the locking position, a cam carried by the latch adapted to be engaged by the holding member to rotate the latch into the open position upon movement of one of p the elements toward the other, this cam being located on and made a part of the latch handle.

Signed at Chicago, county of Cook and State of Illinois, this 20th dayof October CHARLES W. 1mm.
