ASSIGNOR TO CHICAGO FORGING & MANU- OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS HOOD LATCH Application filed July 5,
My invention relates to a securing member which is particularly adaptable for use as a hood latch whereby an automobile hood or similar closure may be held in position. One object of my invention is to provide such a latch which shall urge such a closure not only downwardly but laterally. Another objectis the provision of such a latch which shall compensate for and conform to changes in relation of the closure to the abutment against which it is thrust and which shall compensate for changes in the position of the latch engaging member on the closure. Another object is the provision of a device of the type herein described which shall be cheaply manufactured and eiiicient in use. Other objects will appear from time to time in the course of the specification and claims.

cation. In case of necessity, however, the apertures 13 do permit of a change of location. B indicates an outwardly projecting lip or flange along the bottom of the member B. The member B is herein shown, as in Figure 1, as arcuate or rounded in cross-section both in a plane parallel with the face of the hood and in a plane perpendicular to it.
Referring particularly to Figures 1 and 2 C indicates a base member secured to the frame member A as by the bolts 0 and nuts C It includes the upwardly extending collar C which receives and holds the tube C Such a tube is inwardly upset at the top as at C to leave an aperture conforming generally in shape and diameter to the pin D. The pin is provided at its bottom with a head D and passes through a washer or abutment member D The spring D is compressed between such washer and the head D and tends normally to draw the pin D downwardly towards the frame A in the dotted line position shown in Figure 2.
Pivoted to the upper end of the pin D is the combined handle and latch member gen erally indicated as E which includes the latch or toggle member E the lower end of which, rounded as at E is adapted to engage the abutment member B on the hood A Associated with the toggle or latch member E and herein shown as integral with it is the handle or finger ring E The lower portion of the member E, more or less squared as at E is adapted to engage the top of the tube C when the latch is released and takes the dotted line position shown in Figure 2.
Referring to Figures 3, 4 and 5 a variant form of the device is shown, the pin D being provided with the handle member generally indicated as G which includes the shroud G surrounding the upper end of the tube, the handle portion proper G and the laterally projecting lug G Pivoted to said lug is the toggle or lever Gr with the rounded end G adapted to engage the abutment member B G indicates a coil spring adapted 11ormally to yieldingly move the member G toward the side of the hood A and away from the shroud G when it is released from the abutment B A variation of the end Gr of the member G is shown, which is also applicable to the member E shown in Figures 1 and 2. It is provided with a central notch or channel H adapted to seat upon a ridge or projection H formed in the abutment member B Referring to Figures 6 and 7 I illustrate a variant form of my device in which the handle member J is secured to the top of the pin D and is provided with a lug or plurality of lugs J through which passes the pivot pin J to which are pivoted the arms J 3 which join to form the latch or toggle member J 4 the lip or end J of which is adapted to engage the abutment member B J indicates a spring or similar yielding means tending normally to hold the latch in the position shown in Figure 6.
Figure 8 indicates a further variant'form in which in the place of the fixed cylindrical guide C of the other forms the pin K is fixed in the base member K and is therefore normally rigid in relation to the frame A. The pin K is provided at its upper end with an enlargement K adapted to act as abutment for the spring L. r
L indicates a cylinder surrounding said pin and spring and provided at the bottom with the inturned portion L which serves to hold the washer or spring abutment L The normal effect of the spring L is to move the cylinder L downwardly along the pin K. Secured to the upper end of the cylinder L is the head portion L herein shown as sur rounding the end of the tube or cylinder. It includes the upwardly extending lugs L to which is pivoted the toggle member L to which is associated the handle or finger ring L. L is a fiat spring opposed to the por tion L of the handle member and is adapted normally to urge it into the dotted line position shown in Figure 8, when it is withdrawn from the abutment B It will be realized that whereas I have described and shown a practical and operative device, nevertheless many changes might be made in the size, shape, number and disposition of parts. I therefore wish my description and drawings to be taken as in a broad sense illustrative and diagrammatic rather than as limiting me to my specific showing.
The'use and operation of my invention are as follows: i
Stated generally the general characteristic of my invention is the employment of a guide, the tube C or the pin K, which projects upwardly in generally fixed position on the frame A. It may be parallel with the face of the hood A or it may be inclined thereto, but it is preferable that whatever its relation, it be a constant relation, the tube or pin serving as a fixed guide. Upon such fixed guide I position a movable element, the pin D of Figures 1 to 7 or the cylinder or tube L of Figure 8. Upon this movable member I position a lever or latch or toggle which is in flexible or pivotal relation with the moving member. The length of such latch member must exceed the distance between the movable member .and guide and the opposed abutment B on the hood. Since the spring D or L tends to urge the movable tube or pin downwardly along the fixed guide and since the pivot of the latch is positioned substantially above the point of engagement between the inside end of the latch and the abutment on the hood, the downward movement of the movable member tends not only to exert a downward thrust against the member 13 but also to direct a lateral thrust. When, in response to such downward thrust the hood is moved as far downwardly as itcan, further downward movement of the movable member tends to clamp the hood inwardly against the abutment A and when this movement is effected, no further downward movement is possible. Rattle and displacement isprevented and the lower edge of the hood is firmly but yieldingly locked against the abutment A There are many variations possible without departing from the spirit of my invention and I have illustrated a fixed tube as a guide for a movable pin and a fixed pin as a guide for a movable tube. I have also shown, as in Figures 1, 2 and 8, a combined handle and latch member pivoted to a movable pin or tube, whereas in Figures 3, 5, 6 and 7 I have illustrated handle members fixed in relation to the movable member, the latch member being pivoted to the handle member or to the movable member. In all cases the general principle of operation is identical, the downward movement of the movable member causing both downward and inward pres sure against the hood.
I find it under some circumstances preferable to provide yielding means for withdrawing the latch from alignment with the abutment B when the latch is released. In the form of Figure 2 the spring D has this effect, drawing the portion E of the handle member down against the top of the tube 0*. In Figures 3, 5, 6, 7 and 8 I employ separate spring means tending to withdraw the latch member when released. I may, if I wish, dispense with such means, particularly in the forms wherein the latch and handle are united. In such case when the handle is upwardly drawn to release the latch the handle and latch may be rotated out of alignment with the abutment B the fixed member and the movable member being preferablynot held against rotation.
